T at whom it may concern.-

Be it known that 1, JOHN J. HE'YS, of Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Sole-Cuttin g Machines, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

In said drawings, Figure 1 is a front elevation of so much of my machine as is requisite to show my present improvements and their mode of operation. Fig. 2 is an elevation taken at the right-hand side of Fig. 1. Fig. 3 is a top plan view of Fig. 1. Fig. 4: is a sectional elevation, the section being taken as on line Z Z, Fig. 3, and the view as from the righthand side of Figs. 1 and 3. Fig. 5 is a detached vertical section taken as on line Y Y, Fig. 3, and viewed as from the right in that figure. Fig. 6 is a detached perspective view of the cutting-die as prepared for use in my improved machine. Fig. 7 is a detached perspective View of the follower and attached parts that coact with the cuttingdie. Fig. Sis a detached elevation of the dieplate, the follower, and coacting parts. Fig. 9 is a rear side elevation of the finger-guard plate, the guide rod, and attached parts. Fig. 10 is an elevation of the die-plate and die when said plate is turned out to the front as for adjustment of the die. Fig. 11 is a side elevation showing the devices by which the treadle is locked when the die-plate is turned out to the front for adjustment, as in Fig. 10, so that the machine cannot then be started. Fig. 12 is a top plan View of the treadle shown in Fig. 11.

The object of my invention is to furnish divers additions to and improvements upon the sole-cutting machine patented to me by United States Letters Patent No. 521,793, dated June 26, 1894; and the invention consists in the various improvements and the combinations thereof that will be next here in described and then pointed out in the claims.

Referring again to said drawings, A A represent the side frames of the machine, which are substantially the same as shown in my said former patent.

B B are reinforcing-rods inserted in the front portion of frames A, extended above said frames and supporting the top eross-girt D, held in place by nuts C threaded on said rods in a well-known manner.

A rotarycutting-block His mounted in the machine, and it can be both rotated and vertically reciprocated, to come in contact with the cutting-die 0, either by the means shown in my said former patent or by other means, as desired, the rotation and reciprocation of a cutting-block being both old need be no further alluded to at this stage of the case.

E represents a lever driven as in my said former patent, or by other means, to actuate connector F, which is pivoted to and moves clearer G back and forth on block H for removal of the sole and trimmings therefrom after being cut thereon.

Girt D is formed with two downward projections a a, in which are inserted the pins 1 5,whieh pass through bosses formed upon dieplate b, so as to aid in supporting the same, the rear edge of said plate when in position for use being supported by the catch-lever12, pivoted at 13 upon a bracket secured to girt D, said lever engaging the lower side of b, as shown in Fig. 4, and said lever being pressed into engagement with b by the spring 14, as shown. A small spindle 1 passes centrally through girt D, and a spring 2 seated in an enlarged chamber in the girt acts expansively upon the enlarged head 3 of said spindle at its lower end, while the lock-nuts secured to the upper end of the spindle limit the down ward action of the spring, as in said patent. In said head 3 of said spindle is inserted a small plunger 4 upon which is arranged a spring 5 seated in head 3 to force at down constantly upon saddle q, as shown in Fig. '7, and for purpose to be explained.

The cutting-die c is adjusted and secured to the under side of plate Z) in the following manner: Two small pins ff, united by bar 1 are inserted in holes in plate I) so as to be forced in and drawn out by slight pressure, and when latch-lever 12 is released from plate Z) the latter is swung forward on pins so that pins f extend horizontally to the front and the straighter or outer side of die 0 is then placed upon them, as shown in Fig. 10, and the notch or recess d in the top edge of the die being seated upon rib a, formed upon plate I), the die is then looked to plate I) by pins g that eXtend from brackets 7, secured by screws 8 to plate I). It is thus shown that die 0 is always secured to plate I) in exactly the same position in relation to its side and end cutting-edges, as the pins f and rib c constitute three bearings, said pins governing the sidewise position of the die, while rib e entering notch d governs its lengthwise position, and hence the pins 9 should fit loosely in the die, their only office being to force it against plate b. More than this, by properly positioning pins f, as shown, at the proper distance from the toe and heel part of die 0 all sizes of dies can be by the same means adjusted upon the same pins f without change of position of said pins or notch cl and rib e. A spring (shown at 9, Fig. 8) bears at top against dieplate I) and its lower end bears against bar i that unites pins ff, and serves to force said pins outward, as shown in Fig. 8, when die 0 is removed. Two rods n it pass loosely through plate Z) and have nuts 19 p threaded upon their upper ends, said nuts being interlocked in saddle q seated upon die-plate Z). Said rods at their lower ends are secured in plate Z, which at or near its lineal center is formed with ears through which pin m passes, and a follower j arranged in die 0 and below plate I is by its ear 7c loosely held upon said pin m. A pin t secured in the end of plate Zpasses loosely through follower j, so that when the latter is level said pin does not project from it, and a coiled spring w interposed between l and j on the opposite side of pin m tends to force j downward and so cause pin 25 to project below follower j, the object being that said pin will force the cut sole away from follower j and so cause it to fall away from said follower in case it should stick thereto.

Another important advantage of the pivoted follower j consists in the fact that when so arranged to rock upon pin 'm in all directions it will always hear equally upon all parts of the sole that is being cut, and hence if, as often occurs, the sole is thicker at one end or side than the other the follower will bear with equal force upon all parts of it, which is of great importance in frictioning the sole when feeding it beneath the cuttingdie.

Saddle q is constantly pressed down upon plate I) by a small plunger 4 in the enlarged end of spindle y by spring 5 arranged above it, as shown in Fig. 4, and when the cuttingblock is forced upward till saddle q bears against spindle y then the force of spring 2 will resist the further upward movement of the moving parts, and it will force the sole out of die 0 when block ll decends.

The object of plunger 4, actuated by spring 5, is to hold the sole by friction upon block 11 while being fed beneath follower j upon said block, and it prevents the movement of the sole beyond the distance required by the fingers 58, against which it bears, the force of spring 5 being exerted upon buffers 20, secured upon rod 19, which buffers bear directly upon the sole when it is being fed beneath the die.

Brackets 1.5 are secured to plate I), as shown in Fig. 4, and the guide-rod 19 is carried by curved links 13, connected with said brackets 15 and said plate, (see Figs. 1 and 4,) and on said rods 19 are arranged the cushions 20, which prevent the operator from inserting his fingers beneath said rod so as to be between the cutting-die c and the cutting-block II when the machine is in operation. A guardplate 21 is secured at its lower edge to guiderod 19 by the short fingers 10, while at its up per edge a U-shaped piece 23 is united to it and has a screw 22 threaded in it at top, as shown in Fig. 9. The arms of said piece 23 stand away from plate 21 and pass upon each side of bolt 24 and are held by the head of said bolt, as shown in Fig. 10, where said arms are shown in section, said screw 22 passing down to and being seated on the head of said bolt 24, as shown in Fig. 4. When it is desired to swing die-plate b to the front, as shown by dotted lines in Fig. 4, the handle of latch-lever 12 is drawn to the front till the catch on the lower end of said lever is released from the die-plate, when by actuating arm 26, Figs. 2 and 11, rigidly mounted 011 shaft 25, a rigid arm 27 will thereby be depressed, and the rod 29, which at one end is pivoted to arm 27 at 28, while its opposite end is pivoted at J to dieplate b, will by said means force said die-plate to swing on its pivots 45 to the front, as shown in Fig. 4;

and by the same motion rod 31 that is pivoted at 30 to arm 36, that is pivoted at 28, is swung forward upon its lower pivot 32, thereby causing its rigid lower arm 31 to swing rearward, thus forcing its hook 33 into contact with catch 34, secured to treadle 35, thereby positively locking the same till the die-plate Z1 is returned to position with guardplate 21 and the guide-rod 19 is in position to protect the fingers of the operator, and the treadle is unlocked and liberated by the reverse action of the parts with which it is connected, as just explained.

For the purpose of feeding the pieces of leather upon block H to be cut by die 0, I arrange a table, (shown at 37,) secured in place by bolts 61, as shown in Figs. 2 and 3.

A toothed rack 38 is arranged to slide on.

table 37, and it is engaged by the correspondin gly-toothed arc of a circle 39, secured upon shaft 40, that is arranged and secured beneath table 37. Said arc is vibrated back and forth by means of a reciprocating lever 6, that may be driven as in my said former patent, or by any suitable means, and to this lever is pivoted rod 41, that at its respective ends is right and left hand screw-threaded to fit in hubs that are pivoted to said lever and to arms 44, secured upon shaft 40, a handwheel 42 being secured 011 said shaft-rod for IIO the purpose of adjusting the length so that the feeding devices driven by shaft 40 can be moved to the exact positions required at each end of their stroke, a lever-nut 43 being arranged to be turned against the socketed end of rod 41 to lock the rod when properly adjusted. A feed-slide 46 is secured upon and carried by rack 38, and at its outer end abolt 47 is interlocked in said slide, and upon said bolt are secured by lever-nut 65 the converging ends of connectors 48, the outer ends of which are engaged by pivots 51, which are seated in bushing 50 of fingers 52, arranged in oblique slots 4:9. (Shown in Fig. 3.) Said fingers 52 are thus at their rear ends pivoted to connectors 48, and they are also pivoted to block 55, that moves in slot 56 of table 37 by screws 62, that pass through blocks 54:, seated in the outer arm of angle-levers 53.

Two angle-levers 53 are pivoted at 64 to feed-slide 46,and their longer arms are toothed and interlock, as shown in Fig. 3, while their outer arms embrace blocks 54: and are by screws 62 attached to fingers 52. A coiled spring 56, having its ends attached to the outer arms of levers 53, tends constantly to draw said arms and fingers 52 inward, and hence, with slot 49, formed in table 37 to guide the left-hand finger 52, Fig. 3, by means of block 55 sliding therein, both fingers 52 are governed by the curvatures of said slot, and hence both of said fingers approach toward and rccede from sole-blank 59 with equal rapidity.

Slot 57 upon its outer side is formed straight, while the inner side curves inward, and hence if sole-blank 59 is of a length to barely be admitted between said fingers then the block 55 will follow the outer line of slot 57, while if said blanks are shorter and require said fingers to move toward each other, in order to grip the end of the blank, said blocks follow the inner line of said slot till the sole is so gripped.

The office of adjustable fingers 58, mounted on feed-plate 46, is to serve as the means for movingblanks 5 9 into proper position on block II for cutting by the die 0, the endwise position of said blank being obtained by the action of fingers 52, as already explained.

The gibs 60 are for the purpose of securing feed-slide 46 in place and to yet allow it a free reciprocating back-and-forth motion on table 37.

In practice the sides of the sole-leather are first cut into strips the width of which is practically the length of blank 59, then said strips are cut into pieces or blanks, as shown at 59, and in this form are sold by leather-cutters to makers of shoes who then moisten the blanks and then pass them back and forth through a rolling-machine to consolidate the leather; and in this operation some are stretched more and some less, so that in the same bundle, of one size, there will be a variation of half an inch in length in some of the soles, and there will be a corresponding difference in the width of the soles from the same cause, and in order to utilize all that is possible of the larger soles the smaller ones must be cut as close as possiblehence the object obtained in having studs f arranged on the outer or straight side of the die 0 and at alimited distance on each side of the widest part of the sole respectively, for positioning the die, and then arranging fingers 58 in a corresponding position to govern the sole when adjusting it on block II preparatory to being cut as shown in Fig. 3; and for the same reason it is requisite that fingers 52 have a self-adjustability in order to accommodate themselves to the varying length of soles which they are to grasp and hold while being moved beneath the die.

The ends of fingers 52 and 58 are formed with a groove or recess 67 in which the ends of blank 59 are received and held when said fingers move against it.

It will be observed that slots 49 are formed oblique to each other, their inner ends being farther to the rear than their outer ends, so that when the free or inner ends of fingers 52 move toward blank 59 they will by the same act move bodily to the front and when they move outward they will move bodily to the rear, and by this means the inner ends of the fingers will be practically at the center of the width of blank 59 at all times.
