LASTING MACHINES Filed Nov. 1, 1952 4 Sheets-Sheet 4 films]: for John Tlancaszer By his fzor w United States Patent LASTING MACHINES John T. Lancaster, Newton, Mass, assignor to United Shoe Machinery Corporation, Flemington, N. J., a corporation of New Jersey Application November 1, 1952, Serial No. 318,230 35 Claims. (Cl. 12-1) This invention relates to lasting machines, and is herein illustrated as embodied in a machine especially adapted for use in lasting the covers of platform shoes. It will be understood, however, that features of this invention are not limited in utility to use in a lasting machine of that particular type or to embodiment in a machine of the exact mechanical construction herein disclosed.

One of the operations involved in the manufacture of platform shoes of the slip-lasted type consists in tensioning the platform cover, in a direction extending heightwise of the platform, drawing, or wiping, the marginal portion of the tensioned cover inwardly over the bottom face of the platform and pressing this marginal portion of the cover against the bottom face of the platform to cause it to adhere thereto by means of adhesive previously applied to the platform and/or platform cover. Because of the similarity between these steps and the steps involved in the lasting of the upper materials of certain types of conventional shoes, this operation has become known throughout the trade as platform cover lasting or cover lasting. Thus, in this specification as well as in the claims appended thereto, unless otherwise indicated by the wording or by necessary implication, the term lasting is used in a broadened sense and is intended to embrace not only the lasting of conventional shoes but also the analogous cover lasting and platform cover lasting operation.

It is a principal object of this invention to provide a novel and improved lasting machine which is not only especially adapted for use in the lasting of the covers of platform shoes but also for use in the lasting of conventional shoes. Accordingly, the herein illustrated machine is provided With novel means for tensioning the stock to be lasted and for wiping its lasting margin inwardly over and for pressing it against the bottom of the shoe in dilferent locations progressively along the marginal edge of the bottom of the shoe as the shoe is fed along relatively thereto. More particularly, this tensioning and wiping means comprises a rotary disk member preferably having a roughened peripheral operating surface which is mounted for rotation in a plane substantially perpendicular to the plane of the bottom of the shoe and for reciprocation in a plane substantially parallel to the bottom of the shoe and, co-operating with this disk member, is a tensioning finger which is mounted for oscillation about the axis of the disk member and is adapted to hold the lasting margin of the stock intermittently against the operating surface of the disk member in predetermined time relation to the reciprocating movements of the disk member. With this arrangement, successive portions of the stock to be lasted are tensioned by the combined actions of the rotating disk member and oscillating tensioning finger and the lasting margin of the stock is wiped in over and pressed against the bottom of the shoe by the rotating disk member, during each reciprocating movement thereof.

For feeding the shoe along to present successive portions of the cover to the tensioning and wiping action of the disk member and tensioning finger, a presserfeedfoot is provided and this presserfeed-foot is associated with the tensioning finger. In addition to its oscillating movement, the tensioning finger, together with the presser-feed-foot which is associated therewith, are mounted for reciprocation in a direction extending laterally of the disk member and means are provided for reciprocating these members in predetermined time relation to the reciprocating movements of the disk member thereby to elfect a step-by-step feeding of the shoe. Preferably, and in the herein illustrated machine, the resser-teedfoot is arranged to engage the lasted margin of the stock and apply additional pressure thereon for augmenting the pressing action of the tensioning and wiping disk.

In order to position the shoe relatively to the wiping and tensioning disk, the tensioning finger and the presserfeed-foot, the herein illustrated machine is provided with rotary means for engaging the stock to be lasted adjacent to the marginal edge of the shoe bottom. Preferably, and in the herein illustrated machine, this positioning means comprises a pair of disks which are mounted for rotation in a plane parallel to that of the wiping and tensioning disk and means are provided for rotating these disks in a direction such that, in addition to their positioning action, they tend to upwipe the stock to be lasted during the operation of the machine, and thereby facilitate the tensioning of the stock by the tensioning and wiping disk and its co-operating tensioning finger.

In the manufacture of slip-lasted platform shoes, the platform cover, upper and sock-lining are first stitched together along their marginal edges. Then, after a last has been inserted into the upper and a platform spotted on the sock lining, the cover is turned down over the edge face of the platform, prior to the lasting operation. It frequently happens that irregularities or bunches remain in the cover, in a location adjacent to where it is attached to the upper and, these irregularities or bunches may not be removed in the subsequent cover lasting operation. With the view of overcoming this difiiculty and especially to adapt the machine for use in cover lasting, the herein illustrated machine is provided with means for applying yielding pressure to successive portions of the cover, adjacent to the location where it is joined to the upper, during the operation of the machine. More particularly, this means comprises a yieldably mounted rotatable member having a stepped peripheral operating surface for engaging the cover where it is folded over on itself and joined to the upper, this member being arranged to smooth out all irregularities or bunches, in the cover at that location, as the lasting operation proceeds. By thus smoothing out these irregularities or bunches, a superior cover lasting operation is assured.

The above and other objects and features of the invention will appear in the following detailed description of the preferred embodiment thereof, illustrated in the accompanying drawings, and will be pointed out in the claims.

Fig. 7 is a timing chart.

Referring to these drawings, the operating elements of the machine illustrated therein comprise a wiping and tensioning disk 10, a pair of upwiping disks 12, an oscillating tensioning finger 14 which co-operates with the disk 10, a resser-feed foot 16 and an auxiliary tensioning and guiding disk 18. These several operating elements are associated with a hollow head casting 20 and are operated by mechanism contained within this head casting. It will be understood that this head casting is intended to be mounted on a support of suitable height such, for example, as a column or bench, not shown.

The Wiping and tensioning disk 16 is secured to a cross shaft 22 which is journaled at its opposite ends in a pair of arms 24, 24 extending downwardly and forwardly Figs. 1 and 2. This bracket member is pinned to one end of a rod 28 which is mounted for sliding movement in a bore 30 formed in a centrally disposed upstanding portion 32 of a cross member 34, associated with the head casting. At its opposite end the shaft 28 is provided with a vertically disposed groove 36 in which there is received a roller 38, Fig. 2. This roller is carried by one arm of a bell-crank lever 40 which is pivotally mounted on a cross shaft 42, sup ported in the head casting. Carried by the other arm of this bell-crank lever is a cam roll 44 which is received in a cam track 46, formed in one side of a cam block 48, Figs. 1 and 2. This cam block is secured to a main power shaft which is journaled at its opposite ends in the head casting 20 and is adapted to be connected to a drive pulley.52 by means of a pin clutch, described below. The cam track 46 is so shaped that the rod 28 and the wiping and tensioning disk 10 are reciprocat ed through a stroke of predetermined linear extent, see Fig. 4, each time the power shaft 58 makes a complete revolution.

During its reciprocating movements, the disk 10 is continuously rotated in the following manner. Secured to one end of the cross shaft 22 is a spiral gear 60 which is in mesh with another spiral gear 62. The gear 62 1s pinned to one end of a shaft 64 which is journaled in a bearing boss 66, formed integrally with the bracket member 26, a collar 68, pinned to this shaft, acting with the gear 62 to prevent axial movement of the shaft 64 in the bearing boss 66. This shaft also passes through a bore in the upstanding portion 32 of the bracket member 34 and, at the end opposite to that on which the gear 62 is secured, is provided with a plurality of splined teeth 72. This end of the shaft passes through a spiral gear 74 and through a laterally extending hub portion 76, formed integrally with this gear, both the gear and the hub portion being formed with splined teeth complementary to the teeth 72 on the shaft 64. The hub portion 76 of the gear 74 is journaled in a bearing boss 78, formed integrally with the head casting 20, Fig. 1, and secured to this hub portion is a collar 80 which, together with the gear 74, prevents axial movement of the hub portion and gear relatively to the boss 78. The gear 74 is in mesh with a spiral gear 82 which is secured to the power shaft 50. With this arrangement, when the power shaft 50 is connected to the drive pulley 52, the wiping and tensioning disk 10 would be rotated continuously, in the direction of the arrow Fig. l, and at the same time reciprocated back and forth between the two positions shown in Fig. 4.

The two upwiping disks 12, 12 are joined together by an intermediate hub portion which is keyed to a cross from a bracket member 26,

shaft 92, Fig. 3. This cross shaft is journalcd in two forwardly projecting portions 94, 96 of the cross member 34 and secured to one end of this shaft is a pinion gear 98. This gear is in mesh with a second pinion gear 100 which is formed integrally with a belt pulley 102 and journaled on a stud 104, mounted in the forwardly projecting portion 96. A round belt 106 connects this pulley to a second pulley 108 which is secured to the power shaft 50, Pig. 2. Thus, when the power shaft is connected to the drive pulley 52, the two upwiping disks 12, 12 will be rotated continuously in the direction of the arrow in Fig. 1.

The tensioning finger 14 is pinned to one end of a shaft 110 which is rotatable in a bore 112, formed in a carrier member 114, and is received within a cutaway portion 116 of this carrier, Fig. 5. A compression spring 118 which is offset from the axis of the shaft 110, tends to rotate the finger in a clockwise direction relatively to the presser-feed-foot 16, Fig. l, the limit of movement of the finger in this direction being determined by the engagement of its upper end with carrier member 114, in the cutaway portion 116. The presser-feed-foot 16 is secured to the carrier member 114 by means of a screw 120, Fig. 5. The carrier member 114 has two extending portions 122, 124 in which there is secured a square rod 126. This rod is slidable in a square hole 128, Fig. 5, formed in one end of an arcuately shaped actuating member 130, Fig. 1, which is pivotally mounted on the cross shaft 22 by means of two radially extending arms 132, 132, Fig. 2. In its other end, the actuating member is provided with a plurality of gear teeth 134 which are in mesh with rack teeth 136 out in a rack block 138, Fig. 1. This rack block is secured to one end of a rod 140 which is slidably supported in two bearing bosses 142, 142, formed integrally with the portion 32 of the cross member 34. On its opposite end, this rod is provided with a vertically extending groove 144 and fitted in this groove is a roller 146 which is secured to one arm of a bell-crank lever 148. This bell-crank lever is pivotally mounted on the cross shaft 42 and carries, on its other arm, a cam roll 150 which is received in a cam track 152, cut in the cam block 48, Fig. 1. This cam track is so shaped that the rod 140 and rack block 138 are reciprocated in predetermined timed relation to the reciprocating movements of the wiping and tensioning disk 10 and, as a result of the reciprocating movements of the rack block 138, the actuating member 130, carrier 114 and tensioning finger 14 and presser-feed-foot 16 which are mounted on the carrier are oscillated about the axis of the cross shaft 22 for a purpose which will presently appear.

In addition to the oscillating movements just referred to, the tensioning finger 14 and the presser-feed-foot 16 are reciprocated, laterally of the wiping and tensioning disk 10, in the following manner. The upstanding portion 124 of the carrier 114 is formed with an arcuately curved open-sided groove 158, Figs. 2 and 5, in which there is fitted a roll 160. This roll is carried on an arm 162 which is pinned to, and extends downwardly from, one end of a shaft 164. This shaft is journaled in a bearing boss 166, formed integrally with the bracket member 26, and extends through bores in two ears 168, 168 which extend outwardly from the portion 32 of the cross member 34. A collar 170 cooperates with the arm 162 to prevent axial movement of this shaft in the bearing boss 166. The right-hand end of this shaft, beyond the collar 170, is formed with a plurality of spline teeth 172, Figs. 1 and 2, which fit into a splined bore 174 in the hub portion of an arm 176. Pivotally mounted on the lower end of this arm is a block 178 which carries a pin 181) that is slidably received in a bore 182 formed in one end of an arm 184. This arm is slidably mounted on the cross shaft 42 and, adjacent thereto, carries a cam roll 186 which is received in a cam track 188, out in the peripheral surface of the cam block 48, Fig. 2. This cam track is so shaped that the carrier 114, and also the tensioning finger 14 and presser-feed-foot 16, are recip-, rocated back and forth, laterally of the actuating member 130 and relatively to the disk 10, once during each rotation of the shaft 50 and in predetermined timed re lation to the oscillating and reciprocating movements of these members and the reciprocating movements of the wiping and tensioning disk.

The auxiliary tensioning disk 18 is rotatably mounted on the outer end of a stud 198 which is secured to a bracket member 192, Figs. 1 and 3. This bracket member is entered for vertical movement in guideways formed in the cross member 34 and is provided with a series of rack teeth 196 which are in mesh with pinion teeth 198 out in a gear quadrant 290. This gear quadrant is journaled on a stud 202, Fig. 3, and associated with this stud and the gear quadrant is a coil spring 204 which tends to rotate the quadrant in a clockwise direction, Fig. 1, and thereby elevate the auxiliary tensioning disk 18 to the position shown in Fig. l. The disk 18 is provided with a stepped peripheral surface 206, for a purpose that will presently appear.

As suggested above, the drive pulley 52 is adapted to be operatively connected to the main power shaft 50, to which the cam block 48, spiral gear 82 and belt pulley 108 are secured, by means of a pin clutch. Referring to Fig. 2, this clutch, which is of conventional construction, comprises a hub portion 210 which is formed integrally with an axial extension 212 of smaller diameter and secured in any suitable manner to the shaft 50. Mounted in the hub portion 219, which is journaled in a bearing boss 214 formed in the head casting 20, is a plunger 216. This plunger is urged yieldingly, by means of a spring, not shown, in a direction to project beyond the hub portion 211) and into a hole 218 formed in a hub 228 on the pulley 32, thus connecting this pulley to the shaft 50. For withdrawing this pin from the hole 218, to disconnect the power shaft 50 from the drive pulley 52, which is driven from a suitable source of power, not shown, by means of a belt 222, the following arrangement is provided.

Formed integrally with the pin 216 is a head 230 having an inclined operating surface 232. Pivotally mount-ed on a stud 234 is an actuating lever 236 one arm of which is provided with an inclined operating surface 238 which is complemental to the surface 232 on the head 230. Connected to the other arm of this lever is a link 240, which in turn, is connected to one arm of another lever 242 that is pivotally mounted on a cross shaft 244. Also connected to this arm of the lever 242 is a coil spring 246 which yieldingly holds the levers 236, 242 in the positions shown in Fig. 1 of the drawings as determined by a stop pin 248. A treadle rod 250, which is connected to the other arm of the lever 242, extends downwardly to a foot treadle not shown. As will be apparent, when the foot treadle is released, the lever 236 will assume the position in which it is shown in Fig. 1 and the pin 216 will be projected into the hole 218, thereby connecting the shaft 50 to the pulley 52. When the treadle is depressed, the lever 236 will be swung in a clockwise direction, Fig. 1, so that its right-hand arm, which is provided with the operating surface 238 and is arcuately curved as shown, is brought into engagement with the cylindrical surface of the axial extension 212 of the hub 21! alongside of the bearing boss 214. Now, when the inclined surface 232 on the head 230 comes into engagement with the inclined surface 238 on the lever 236, as the hub 210 rotates in the direction of the arrow Fig. 1, the pin 216 will be forced out of the hole 218, thereby disconnecting the shaft 50 from the pulley 52. Immediately after this pin has thus been withdrawn from the hole 218, the hub 210 and shaft 50 will be brought to a stop by the frictional action of the inclined surfaces 232, 238 and the resistance of the spring pressed plunger 216 to further movement in that direction. Thus, the shaft 59 and the various operating elements which are driven therefrom are brought to a stop in predetermined positions, for a purpose which will presently appear. Upon release of the foot treadle, the lever 236 is returned to the position in which it is shown in Fig. l by the spring 246 and the shaft 50 is again connected to the pulley 52.

The depression of the foot treadle also serves to move the auxiliary tensioning wheel 18 downwardly, against the resistance of the coil spring 204, to the position in which it is shown in Fig. 4. For this purpose, the bracket member 192 extends downwardly beyond the cross member 34 and is provided with an elongated slot 260. Extending through this slot is a pin 262 which is carried on the upper end of a link 264 that is pivotally connected, at its lower end, to the lever 242. When the treadle is released and the lever 242 swung to the position shown in Fig. 1, this pin will be located approximately in the central portion of the slot 269 so that the bracket member 292 and the auxiliary tensioning disk 18 are free to float vertically under the action of the spring 204.

The machine which has just been described operates in the following manner. Before presenting a shoe to be lasted to the machine, the operator depresses the foot treadle and thereby brings the several operating elements to a stop and moves the auxiliary tensioning disk 18 downwardly to the position in which it is shown in Fig. 4 of the drawings. Referring to the timing chart, Fig. 7, the angular disposition of the hub 210 of the clutch on the shaft 50 is such that these parts come to a stop with the wiping and and tensioning disk in the extreme righthand position, Figs. l and 4, and with the tensioning finger 14 and presser-feed-foot 16 in the angular positions shown in solid lines in Fig. 4 and in the lateral positions, relatively to the disk shown in Fig. 6, these positions corresponding to the zero position of the shaft 50 as indicated on the timing chart. The operator now takes the shoe, herein illustrated as a slip-lasted shoe comprising an upper U, assembled on a last L together with a sock-lining S, a platform P and a platform cover C, in his hands and, after placing it substantially in the position shown in Fig. 4, he releases the foot treadle thereby permitting the disk 18 to be elevated to the position shown in Fig. l and starting the rotation of the shaft 50. Following the timing chart, Fig. 7, from left to right, while the disk 10 which is now rotated in the direction of the arrows Figs. 1 and 4 remains in its extreme right-hand position for the first 120 of rotation of the shaft 50 the following actions of the tensioning finger 24 and presser-feed-foot 16 occur.

First, the rack block 138 is moved to the left by cam track 152, thereby swinging the tensioning finger and presser-feed-foot in a counterclockwise direction to the angular positions, relatively to the disk 10, illustrated in Fig. 1, in which positions the tensioning finger 14 is inserted beneath the lasting margin of the platform cover, adjacent to one side of the disk 10, and the presserfeed-foot 16 is pressed against the upper surface of the cover, beneath the disk 10, as shown in Fig. 6, these movements being completed at 60 of rotation of the shaft 50. To facilitate the insertion of the tensioning finger 14 beneath the lasting margin of the cover C, the operator may elevate that portion of the lasting margin which is located just to the right of the disk 10, Fig. 6, before releasing the foot treadle. Next, the tensioning finger 14 and presser-feed-foot 16 are moved over to the left, relatively to the disk 10, from the positions illustrated in Fig. 6 to the position shown in Fig. 5, by the action of the cam track 188, these lateral movements being completed at of rotation of the shaft 50. As a result of this lateral movement of the presser-feed-foot 16 which is provided on its operating face with serrations, or teeth 300, which frictionally engage the lasting margin of the cover, a feeding movement is imparted to the shoe. Now, the cam track 46 effects movement of the rotating disk 10, together with the tensioning finger 14 and presser-feed-foot 16, to the left until the disk 10 reaches the broken line position shown in Fig. 4. During this movement of the disk 10, the tensioning finger and presser-feed-foot are swung to the angular positions in which they are shown in Fig. 4, inasmuch as the rack block 138 is now held stationary by the cam 152. As a result of these movements of the disk 10 and the tensioning finger 14, which are completed at 210 of rotation of the shaft 50, that portion of the lasting margin of the cover, which is gripped between the periphery of the disk 10, which is provided with serrations, or teeth 302, and the operating surface of the finger 14, which is provided with serrations, or teeth 304, is tensioned and drawn inwardly over the bottom of the platform P by the combined actions of the disk 10 and the finger 14. Also, as the lasting margin of the cover C is thus drawn inwardly, it is wiped over, and pressed firmly against the bottom face of the platform P as the tensioning finger 14 retreats from a position directly beneath the disk 10 to the angular position shown in Fig. 4.

Now, the rotating disk 10 is moved to the right by the cam track 46 and, inasmuch as the rack block 138 is simultaneously moved to the right by the cam track 152, the parts are returned to the positions shown in solid lines in Fig. 4, at 300 of rotation of the shaft 50. During this return movement of the disk 10, it continues to have a wiping action which is directed inwardly from the marginal edge of the platform P because the peripheral speed of its operating surface is greater than the linear speed of its reciprocating movements. Next, the tensioning finger 14 and presser-feed-foot 16 are moved laterally of the disk 10, to the right as viewed in Fig. 5, to the position shown in Fig. 6, by the cam track 188 as the shaft 50 completes a revolution. Thus, during each revolution of the shaft 50, or operating cycle of the machine, the shoe is first fed along and then successive portions of the lasting margin of the cover C are tensioned and drawn inwardly over the bottom of the platform P, by the combined actions of the disk 10 and finger 14, and this portion of the lasting margin of the cover is wiped inwardly over, and pressed against the bottom face of the platform by the disk 10. Subsequently, during the next operating cycle, the portion of the lasting margin previously wiped in over, and pressed against the bottom of the platform by the disk 10, will be subjected to additional pressure by the presser-feed-foot 16, as illustrated in Fig. 6. It will be understood that, prior to the lasting operation, the bottom face and/ or the inner surface of the lasting margin of the cover will have been coated with a suitable adhesive so that it is secured to the platform in lasted position by the pressure applied thereon by the wiping and tensioning disk 10 and presser-feed-foot 16.

Before each successive portion of the lasting margin of the cover C is acted on by the wiping and tensioning disk 10 and tensioning finger 14, it is tensioned in a direction extending heightwise of the shoe by the frictional drag which is applied thereto by the continuously rotating upwiping disks, 12, 12. In order to augment their upwiping, or tensioning actions the operating surfaces of these disks may be provided with serrations, or teeth 306, see Fig. 3. The serrations or teeth 306, however, should not be sharp enough to abrade or otherwise mark the stock being lasted, e. g., cover or upper material, and, if

desired, the disks 12, 12 may be provided with entirely smooth peripheral operating surfaces. The heightwise tensioning action of the disks 12, 12 is facilitated and augmented by the auxiliary tensioning disk 18. As already explained, this disk is provided with a stepped peripheral surface 206 and, during the operation of the machine, this surface is yieldingly urged into engagement with the folded over portion of the platform cover C, adjacent to the location where it is stitched to the sockinglining S and, upper U, see Fig. l, by the action of the coil spring 204. The yielding pressure thus applied to this portion of the cover effectively smooths out all irregularities or bunches which may have formed in the cover at this location and which might not otherwise be removed by the heightwise tensioning action of the upwiping disks 12, 12. In addition, the disk 18 serves as an edge guide roll for locating the shoe laterally in the machine and supports the shoe yieldingly against the wiping action of the disk 10.

Thus after the operator machine in proper position and started the machine in operation, by releasing the foot treadle, all he has to do is to guide the shoe, as it is fed along by the resser-feedfoot, and exert thereon a slight pressure directed inwardly of the machine to hold the cover C, on the vertical edge of the platform, against the upwiping disks 12, 12. Because of the yielding action of the spring 204, the auxiliary tensioning disk 18 is free to assume various heightwise positions to accommodate variations in the thickness of the platform P or platforms of different thicknesses. When the lasting operation has proceeded to the desired extent, either along a selected portion of the periphery of the bottom of the shoe, or entirely around the bottom of the shoe, the operator terminates the lasting operation by depressing the foot treadle, thereby bringing the machine to a stop with the parts in the positions shown in solid lines Fig. 4, as already explained.

Referring to Fig. 4, it will be noted that, in its movement to the right, the disk reaches a position slightly beyond the marginal edge of the bottom of the platform P. Hence, when the tensioning finger 14 and presserfeed-foot 16 are swung in a counterclockwise direction, from the angular positions in which they are shown in Fig. 4 to the positions in which they are shown in Fig. l, the end of the finger will project somewhat beyond the marginal edge of the platform, and will tend to separate the cover from the vertical edge face of the platform if it had become adhered thereto during the previous handling of the shoe. it will be recalled that the finger 14 is constantly urged to swing in a clockwise direction, Figs. 1 and 4, about the axis of the shaft 110 by the spring 118. Accordingly, when this finger and the presser-feed-foot are in the angular positions shown in Fig. 4, the finger 14 will be swung to the full extent of its movement in this direction, as determined by the engagement of its upper end with the cutaway portion 116 of the carrier member 114. However, during the next stage in the operating cycle of the machine, as the finger 14 and presser-feed-foot 16 are swung toward the position shown in Fig. l, the end of the finger 14 will engage the bottom face of the platform P and will be swung reversely into the position, relatively to the presser-feed-foot, shown in Fig. 1. Thus, when the finger and presser-feed-foot are shifted to the left, during the succeeding stage of the operating cycle, the operating surface of the finger 14 will be forced beneath the operating surface of the disk 16 so that the lasting margin of the cover C is gripped between these operating surfaces. Immediately thereafter, as the disk 10 moves to the left and the finger 14 is oscillated toward the position shown in Fig. 4, a strong tensioning pull will be exerted on the cover C. Eventually, as the swinging movement of the finger 14 continues, this finger is swung away from the disk, by the spring 118, thus releasing the lasting margin of the cover to the wiping action of the disk 10.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1.
