Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed September 22, 1914. Serial No. 862,949.

To all whom it may concern:

Be it known that I, VVAn'rER SHAW, a citizen of the United States, residing at Dedham, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements inmachines for inserting in sheet material, fasteners such as eyelets, lacing hooks or the like. The invention is herein shown as embodied in a machine of the type disclosed in Letters Patent of the United States No. 934,066, granted September 14, 1909, on an application of George Goddu, although it is not limited in its application to this or to any particular type of machine.

In certain fastener setting machines, of which that above mentioned is one example, the feeding movement of the work is effected between the insertion of successive fasteners by swinging a work engaging member, such as a punch or setting die, about the axis of a pivoted head or carrying member. Various expedients have been tried for controlling the path of the work feeding tool and making it straighter than it would be if it followed an arc having the axis of the head as a center. This is very desirable or necessary, because in setting large eyelets which are commonly spaced a considerable distance apart, a curved feeding path is objectionable for obvious reasons, With these conditions in view, an important feature of the invention consists in the provision of means for guiding the work engaging tool in a path extending in a substantially straight line across the front of the machine. said means being constructed and arranged to confine the feeding and returning movements of the feeding tool to parallel paths. In the illustrated embodiment of the invention this is effected by providing a guideway extending substantially tangentially with respect to an arc having as a center the axis of the carrier head.

Another feature of the invention relates to an improved organization for handling and punching the two quarters of an upper preliminarily to their presentation to the setting devices. In the machine of the patent above referred to the two quarters of the upper are punched by separate tubular punches cooperating with hardened cutting blocks. the present invention, however, it is proposed to punch both quarters of the upper while they are arranged in contact with each other and by the employment of a single pair of cooperating punching members. As herein shown, the setting devices are so mounted as to leave a free space into which move from opposite sides a solid punch and a tubular punching die. After the two quarters of the upper have been perforated the punching elements are withdrawn and a beveled work separating plate is moved between them to separate the parts of the upper and carry the upsetting die into alinement with the previously punched holes.

This construction has been found advantageous in that it insures the formation of a clean cut hole through each quarter including not only the leather part but also the textile lining or stiffening strip which has heretofore been a troublesome material to punch cleanly. Moreover, it has been found that considerably less power is required to operate a punching combination of this kind and consequently the operation of the machine at high speed is facilitated.

In this connection another feature of the invention consists in a die plate of novel characteristics. In the machine as now organized, it is desirable to locate the upsetting die in advance of the point Where the work is to be punched and it is also desirable to support this die at a point in the rear of the punching position. Inorder to com ply with these conditions, the present invention contemplates the provision of a bowed or sickle-shaped die plate disposed so that the punching tools may operate in the free space at the bend.

The machine herein shown is so organized that the punching and setting tools are moved rearwardlv after the punching operation in order to bring the setting tools into line with the hole previously formed by the punch. Heretofore this movement has not been entirely perpendicular to the feeding m vement. In accordance with one feature of the present invention a perpendicular movement is brought about and all tendency In accordance with one feature of is eliminated of displacing the work in the direction of its feeding movement.

As herein shown the mechanism for imparting the feeding movement to the work is arranged to lose control of the tool carrier during its rearward movement so that its path may be accurately determined by a guideway or similar mechanism.

Another feature of the invention consists broadly in a plurality of guideways for controlling different portions of the path of the feeding tool and separate cams for moving the tool carrier along the respective guideways, each cam being arranged to lose control of the carrier while the other cam is moving it.

Another feature of the invention relates to novel means for presenting corsets or similar goods to the action of the punching and setting tools. As herein shown this means comprises an elongated troughshaped support leading toward the setting tools and having provision for adjustment so that corsets having stiffened edges of different widths may be handled conveniently and the fasteners inserted uniformly and accurately.

Still another feature of the invention relates to the mechanism for actuating the punching and setting tools. As herein shown, these tools are mounted side by side in apivoted head and are successively actuated by a. lever carrying hammers for operating the respective tools. In order to enable the path of movement of each tool to be separately adjusted and controlled, means are provided for separately clamping and adjusting each of the hammers. As herein shown, the clamping means comprise a pair of concentrically arranged bolts so disposed that either one can be clamped or loosened independently of the other.

The features of 'nvention above discussed improve the operation of fastener setting machines upon the uppers of boots and shoes, but they also greatly improve their operation upon textile work, such for example, as corsets, in which it is desirable to set at high speed a large number of eyelets. In fact, these improvements particularly adapt a Duplex eyeleting machine for this class of work.

The features above enumerated and others incident to the invention, will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which Figure 1 is a plan view of the operative parts of the machine;

Fig. 2 is a view in perspective of the front portion of the machine;

Fig. 3 is a view in perspective of the die plate and associated parts;

Figs. 4 and 5 are fragmentary views partly in section of the punching tools;

Figs. 9 and 10 are views of details of the work guiding means.

In the accompanying drawings, the frame of the machine and other parts, unnecessary to the understanding of the present invention, have been omitted for the sake of clearness, and for further disclosure of these parts reference may be had to the patent above identified.

The machine frame is of suitable shape for supporting the moving parts of the machine, a portion 2 being shown in Fig. 6. In the frame is journaled the main shaft 4 which may be driven from any suitable source of power and which carries a number of cams for operating the various instrumentalities. A forked head or carrier 6 is pivotally mounted by means of a pin 8, as shown in Fig. 1, at one end of a bell crank cam lever 9 which is mounted on the machine frame and oscillated by a cam 10 on the main shaft 4. Each branch of the head 6 is provided with two parallel bores, in the outer of which are mounted setting dies 28 and in the inner of which are mounted the cooperating punching elements 32 and 33. Each of the setting dies 28 is connected at its upper end to the forward end of a lever 30, which levers at their inner ends are connected by a tension spring 38 and normally held in such position as to maintain the setting dies in retracted position. Each of the punching members is connected to the forward end of similar lever 34 and these levers in turn are connected by a second tension spring 36 which serves to maintain the punching members in retracted position.

Secured to the head 6 and disposed between its upper and lower branches is a sickle-shaped die plate 52 which carries at its forward end the double faced upsetting die 54. The upsetting die is maintained permanently in alinement with the setting dies 28, the die plate 52 being rigidly secured to the head 6 which carries these members.

The construction of the die plate is shown in detail in Fig. 3, from which it will be seen that the die plate is beveled on that edge which faces the oncoming work and is provided with a square shoulder and stud at its inner end. The head 6 is formed with a socket piece 50 having a squared recess for receiving the shoulder of the dieplate and preventing the latter from twisting, and also with a bore to receive the stud on the die plate. A transverse bore in the socket piece 50 intersects the opening for the stud on the die plate, and a recessed draw pin 56 is arranged in the latter bore and provided with a nut by which the stud and conselquently the die plate may be clamped in p ace.

Pivotally mounted upon the machine frame above and below the head 6 are a pair of actuating levers 20, 22. The lever 22 is provided with a rearwardly extending arm 24 carrying a cam roller which runs in the track of the cam disk 26, by which the lever 26 is oscillated at the proper time. Each of the levers has an arm extending toward the other and these arms carry intermeshing gear teeth so that the oscillation of the lever 22 is imparted to the lever 20 in an opposite sense and equal extent. Each of the actuating levers 20, 22 carries a pair of hammers. of which the longer hammer 72 is arranged to depress its associated punching member while the shorter hammer is arranged to depress its associated setting die.

Each of the levers 20, 22 is slotted at its outer end to receive the body part of one of the hammers upon each of its sides. The body part of each hammer is provided with. a groove disposed in parallel relation with the walls of the slot in the lever, as shown in Figs. 6 and 7, through which extends clamping means. At its edge the body part of each hammer is provided with worm teeth, with which mesh the teeth of a worm screw 81. By turning these screws in the appropriate direction, after loosening the clamping means, either one of the hammers may be adjusted upwardly or downwardly in its carrying lever and consequently the range of movement of the corresponding tool may be adjusted.

The shorter or set operating hammer 70 and the lever 20 are perforated to receive the tubular clamping bolt 74, the latter being flattened upon its opposite sides to pre vent twisting. On one side of the lever 20 the tubular clamping bolt 74 is provided with a head, while at the outer side of the hammer 70 it is provided with a nut 78. A narrow nut or spacing piece is disposed between the hammer and the face of the lever 20 and it will be apparent that by merely loosening the nut 78 the hammer 70 will be released without disturbing the position of the tubular clamping bolt 74 in its relation to the lever20.

The longer or punch operating hammer 72 is recessed in its body portion to receive the head of the clamping bolt 74 and is slotted to permit the passage of a second clamping bolt 80 of such diameter as to fit in the bore of the tubular clamping bolt 74. The bolt 80 carries a'short pin 84'beneath its head which fits into a corresponding slot in the head of the tubular bolt 74 and thus prevents twisting of the bolt 80. The head of the bolt 80 bears against the outer side of the body part of the hammer 72 while its other end extends beyond the end of the tubular bolt 74 and is provided with a nut 82. By loosening this nut, it will be seen that the hammer 72 may be released for adjusting purposes without in any way disturbing the hammer 7 O or any of its clamping parts.

When the machine is at rest, its parts occupy the positions shown in Fig. 6 and the punching members 32 and 33 stand in the path of the longer hammers 7 2. When the machine is started, the punching members are forced toward each other for perforating the work and are then retracted. Subsequently, the cam 10 oscillates the lever 9 in such manner as to move the frame or head 6 rearwardly, carrying the setting dies 28 and the upsetting die 54 into alinement with the previously punched holes. In this movement, the beveled edge of the die plate 52 is advanced between the two layers of the work and these are separated, one passing above and the other below the upsetting die. The setting dies 28, by this movement of the head 6, are brought into operative relation with the shorter hammers 70 and on the next actuation of the levers 20, 22 the setting dies operate to insert an eyelet through each side of the work and clenoh its barrel agalnst the upsetting die 54. l/Vhile the work is held by the engagement of the setting dies with the :lenched eyelets, the head 6 is moved toward the left, as viewed in Fig. l, for feeding the work.

Transverse movement of the head 6 in the feeding operation is effected by the cam 14 which operates upon the head 6 through the pivoted cam lever 13 and the intermediate links 11 and 12. The extent of the feeding movement is controlled by a spacing lever 15 which swings over a graduated plate 16 but this spacing mechanism constitutes no part of the present invention. The head 6 is provided on its lower branch with a forwardly extending projection 40, in which is rigidly set a spindle 42 having at its lower end a roller or runner 44. Mounted beneath the head on the machine frame is a block 46 having its upper face disposed in a plane parallel to the plane of movement of the roller 44. A flanged plate is secured to the block 46 and the flange of this plate, together with the rear edge of a second plate rigidly secured thereto, constitute a guideway 48 in which the roller 44 may move when the head is pushed transversely toward the left by the action of the cam 14'. It will be seen that the guideway 48 is substantially rectangular in shape and is disposed at right angles to the head 6 and tangentially with respect to an are having the axis 8 of the head as a center. The feeding movement of the setting tools is consequently substantially in a straight line. In order to enable the part of the head 6 which carries the roller 44 to move in a straight path, it is necessary to leave the head free for movement slightly from front to rear and this is accomplished by forming a wide portion 11 in the cam 10. WVhen the cam, therefore, has been turned to such a point that the cam roller on the lever 9 enters the wide portion 11 the position of the head 6 from front to rear is controlled only by the action of the guideway 48 on the roller 44.

Preliminarily to the feeding movement the head or carrier 6 is moved rearwardly to bring the setting and feeding tools into line with the previously punched holes. This rearward movement is controlled by a second guidewayformed in the flanged plate on the block 46, which second guideway eX- tends at right angles to the guideway 48, that is from front to rear of the machine. Movement of the carrier along this guideway is effected by the cam 10 acting through the bell crank lever 9. The feed lever 13 is connected at all times to the carrier through the links 11 and 12 but in order to insure that the guideway shall have complete control of the carrier in this part of its movement a wide portion 17 is formed in the cam 14 so that the lever 13 loses control of the carrier while the latter is moving rearwardly. A second wide portion is formed in the cam at a point suitable to free the lever 13 during the forward movement of the carrier.

From the foregoing description it will be seen that the cam 10 moves the carrier from front to rear while the lever 13 is free and one of the two guideways controls, while the cam 14 moves the carrier transversely toward the left (Fig. 1) while the lever 9 is free and the other guideway 48 controls. At the conclusion of the feeding movement the cam 14 moves the carrier toward the right and then the cam 10 moves it forwardly to initial position, these movements being controlled successively as before by the two guideways.

The construction of the punching mem bers is best shown in Figs. 4 and 5. The lowermember 33 is tubular, being of small diameter at its upper end 35' and of enlarged diameter a short distance below its upper end. The upper member 32 comprises a solid punch having its lower end shaped to fit exactly withinthe reduced end portion of the tubular punch 33. The initial position ofthe punching members is shown in Fig. 4. there being sufficient space between them for the introduction of the two pieces of work to be punched. In the punching operation both members are moved toward the work finally perforating it with a punch and die action. The position of the punching members at the conclusion of the punching operation is shown in Fig. 5. The location of the punching members in the machine is such that they operate upon the work at a point located immediately at the rear of the upsetting die 54 and in the free space left by the bend of the die plate.

At one side of the die plate 52 are disposed a pair of work holding and guiding presser feet 60 which assist in directing the work to the tools but these presser feet are not claimed herein, as they constitute a part of the subject-matter of a co-pending application of Fred A. Rumney, SeriLl No. 857 ,7 60 filed August 20, 1914.

In operating upon corsets and similar bulky goods it is important to support the work and guide it to the setting tools in such manner that there shall be no tendency to misplace the work; To prevent the weight of the part of a corset which is not operated upon from pulling the edges where the eyelets are to be set out of place there is provided a trough-shaped support 64 secured to the machine frame and leading toward the setting tools. The trough 64 is intended to receive and guide the stiffened edges of a corset and to this end it is provided at its inner side with an adjustable rib 68 adapted to position the free edges of the corset and at its outer edge with a corresponding adjustable rib over which the body of the work is bent. This lower rib therefore takes under the stifiened edge and so supports the weight of the corset.

In eyeleting corsets two standard widths of stiffened edge are encountered. To meet this condition the inner rib 68 is made adjustable by a predetermined amount equal to the difference in width of the standard edges. To this end a spring pressed stud 67 is set in the rib 68 as shown in Fig. 9. The stud 67 passes through a slot in the base plate of the trough 64 and isprovided at its lower end with a cross-piece 69. The base plate, as shown in Fig. 10, is provided on 1ts lower surface with two recesses shaped to accommodate the cross-piece 69 and con nected by a slot for the stem of the stud 67. The rib 68 is maintained in one position or the other by the engagement of the cross piece 69 in one of the slots of the base plate. lVhen it is desired to shift the rib into its other position the stud 67 may be depressed whereupon the cross-piece 69 is moved out of its recess and the rib may be shifted until the cross-piece seats itself in the second recess.

In operating the machine above described the two edges of a corset are superposed and placed against the face of the rib 68. They are then moved toward the left in Fig. 1 and pass between the presser feet 60 until the point at which the first eyelets are to be set comes in line with the punching members. The machine is then started and the punching members at once perforate both pieces of the work as indicated in Fig. 5. The feeding members are then retracted and the carrier is moved rearwardly by the action of the cam 11 while the cam 14 is inoperative by reason of one of the wide por tions in its track and while the carrier is controlled in its movement by the guideway which extends from front to rear. When this movement has been completed the setting dies are operated to insert and clench an eyelet in each piece of the work. The carrier is then moved transversely by the action of the cam 14 while the cam 10 is inoperative for the reason explained above. At the end of the feeding movement the setting dies are retracted and the carrier is returned to its initial position.

While the operation of the machine has been described with special reference to operating upon corsets or similar articles it will be understood that many of its features may be embodied to good advantage in eyeleting machines intended for general use or in other machines for setting lacing hooks or fasteners of a similar character.
