T at who'ntitntay concern:

Be it known that I; WALTER J. OOOMBS, of Wollaston, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Lacing Hook or Stud Setting Machines, of which the following is a specification.

My invention relates'to machines for setting lacing hooks or studs,.and more espe: cially to.a machine in which the studs are separated from a mass and fed automatically to the devices which insert and set them in the material to which they are to be applied.

q One object ofthe invention is to provide for a constant supply of studs to the setting devices, and this is accomplished by driving the device which separates the studs from the mass of studs in such a manner that it is con- 1 tinuously operated during the intermittent operation of the setting devices.

A further object of the invention is to provide simple and efficient devices for receiving the individual studs and setting them in the material which will allow the material to be Fig. 2

readily and conveniently fed by the operator without any great degree of skill or care on his part. The features bywhich this object is accomplished, as well as those other features of the invention which contribute to the simplicity and efficiency of the machine, will be set forth in the claimsy The features of invention will be best understood from a detailed description of the machine in which I have embodied them,

"which machinel have shown in the accomt a detail plan view of the setting-plate.

I have embodied the. features of my invention in a machine having in many respects the same general construction as the machine shown in Patent No. 277,985, dated May 22, 1883. In this machine the studs are placed in a hopper and are separated from the mass and directed onto a guideway by a verticallyreciprocating plate, which is operated from the cam-shaft which operates the setting devices. This shaft makes a single revolution to feed and set each stud and then stops and remains at rest until the operator steps upon a treadle and again starts the shaft. If the operator keeps his foot upon the treadle, a a number of studs may be set in succession without stopping the shaft. The shaft remains at rest, however, when the setting of the studs is interrupted for the purpose of placing a new piece of material in position or to enable the piece to be properly fed. The

operation of the reciprocating plate is inter rupted whenever the operation of the setting devices ceases, since the plate is driven from the same cam-shaft. It sometimes happens,

therefore, that the supply of studs in the guideway becomes exhausted, necessitating the running of the setting devices idly until the guideway is supplied, thus reducing the capacity and eificiency of the machine. This objection I have overcome by operating the reciprocating plate by a mechanism which may be run without interruption independently of the mechanism for operating the setting devices. V

The hopper in which the hooks are placed is indicated at A, and in this'hopper is located the vertically-reciprocating plate B for separating the studs from the mass and direeling them onto the inclined guideway O. The plate B is carried by a rock-shaft b and is operated by a cam b, which engages a roll carried bya lever b the upper end of which is connected, by means of a link b with the end of an arm 17 secured to shaft 1). The cam-groove b is formed in a disk b to which is secured a gear I), engaged and driven by a gear 11 secured to a shaft 11 The shaft 1) may be continuously driven during the operation of the machine by means of a friction-disk b Figs. 1 and 8, secured thereto and arranged to engage a friction-disk b on the continuously-rotating driving-pulleyD.

The disk 12* is held, in engagement with the disk 17 by a spring I), and so long as the disks are in engagement the cam-disk b is continuously rotated, thereby operating the 5 reciprocating plate B continuously. The operation of the plate B may be stopped at any time by means of a cam-lever 5 the lower end of whichis wedgeshaped and is arranged to engage a collar b on the shaft b and move the shaft longitudinally, thereby disengaging the disks 5 19 In order to avoid breaking or injuring the mechanism in case a stud becomes jammed between the plate B and wallet the hopper so as to interfere with the movement of the plate B, the link 19 is made in two parts with a spring interposed between them, which yields to allow the movement of lever b when the plate B is stopped. One of these parts 20 consists of a tube I), connected with the arm I), and the other part consists of a rod b sliding in said tube and connected with the lever 12 The spring I) is interposed between the end of the tube and a pin b", which extends through the rod Z7 and a slot in the tube.

The studs pass from the plate B onto a guide-plate O, and individual studs are separated from the series of studs on the guide and directed into a guide F, which leads to the setting devices, by a separator G. The stud slides down the guide F, with the front or open side of the hook in advance, into position in front of a reciprocating feedingslide F, by which it is advanced to the setting' devices as in the patent referred to. The separator G is operated by a pin g on a disk D, secured to the cam-shaft D which is arranged to strike the end of a lever 9 40 connected with the separator G by a springarm g The lever g is held in normal position bya leaf-spring g, which bears on a pin g The feeding-slide F is operated by a cam-groove f, formed in the disk D and en- 5 gaged by a roll on the end of the leverf, which is connected with the slide by a link f and a rodf which fits in a recess in the end of the slide and bears against a spring).

The setting devices consist of a spreading and clenching stud oranvil for-engaging the tubular shank of the stud after it has been forced through the material and spreading and clenching the same against the material and a setting-plate which engages and sup- 5 ports the head of the shank While it is being forced through the material and clenched. The spreading and clenching anvil H is secured in fixed position in the overhanging arm H, and the setting-plate l is carried on 6 a plunger J, which holds the plate in position to receive the stud from the guide F and then advances toward the anvil H to force the shank of the stud through the material and against the anvil. After the stud has been set in the material the setting-plate is moved back on the plunger to disengage it from the stud, so that the material may be fed into position to receive the next stud, and the plate is returned to position to receive the next stud as the plunger is retracted. These movements are given to the anvil-plate I by securing it upon a slide t', which is'moved in guides formed in a block 1 carried by the plunger J. A recess 1 is formed in the front of the setting-plate to receive the neck of the stud, and a pocket is formed in the front end of the slide below the plate I to receive the head of the stud. The plate and pocket form a carrier which holds the stud during the setting. When the plunger J is in its lower retracted position, the recess 1 and pocket register with the end of the guide F, so that the hook may be carried forward out of the end of the guide and onto the setting-plate, the head being inclosed by the pocket in the slide t except at the back. By thus forming the pocket in the front of the carrying-slide and feeding the studs forward to the POCkBl'w-i. 6., with the open side of the hook in advance and the neck in the rearihe setting-plate is rigidly supported by the carrying-slide on both sides and at the rear of the pocket, and therefore rigidly and properly supports the end of the stud-shank during the setting.

In order to free the stud from the plate I and the pocket, the slide t' is moved back in its guides after the setting operation is completed. This movement is given to the slide by a spring t", Figs. 5 and 6, which is mounted in a recess in the block I and engages a pin 1?, secured to the slide and working in a slot 11 in the block. The slide is advanced against the tension of the spring by means of a lever 11", pivoted to the block 1 the upper end of which engages the slide and the lower end of which is arranged to ride against a fixed pin as the plunger J is retracted, and thus rock the lever. advanced position by means of a spring-catch pawl i secured to the slide and arranged to engage a shoulder 17 on the block, Figs. 3 and 7. As the plunger J is retracted the lever t rides against pin i advancing the slide i, so that the pawl 6 rides over and engages the shoulder i The slide is in this advanced position when it receives the stud and remains in this position during the advance of the plunger to set the stud in the material. When the stud is forced against the anvil H, the pawl i is disengaged from the shouldert by means of a pin 2' carried in the block I and arranged to lift the pawl from the shoulder. The pin 2' is operated by the movement of the plunger relatively to the block I when the stud engages anvil H. This movement is provided for by fixing the block I on a stud 1 mounted in a hole in the plunger and supported on a stiff spring I The stud 1 is held in position by a pin 1 extending through the plunger and through a slot 1 in the stud. When the stud is forced against the anvil H with suificient pressure to set the stud, the spring 1 yields to allow the plunger to advance relatively to the block 1 The slide is held in its' with the roll L on the bar L which carries the guard. The guard is then moved to dismaterial and stud held between anvil H and plate I holds the slide 2' in position until the pressure is relieved, when the spring t quickly moves the slide 7 back, thus freeing the anvil-plate from the stud, Fig. 4. The material may now be fed while the plunger is being retracted to bring the setting-plate into position to receive the next stud. The stud is retained in position on the anvil-plate as the plunger J advances bya springpressed retaining-plunger K, mounted in the block I and having its end shaped to conform to the shape of the head of the stud. The plunger is held in the block and its upward movement limited by a screw it, the end of which plays in slot formed in the side of the pin.

When the stud is fed to the anvil-plate by the slide F, .the head of the stud rides onto the end of the pin K and the stud is held in position on the plate until it is properly set in the material. The pin K is of smaller diameter for a part of its length, so that a shoulder is formed thereon which engages a shoulder inthe recess in which the pin is mounted when the stud is in setting position. The head of the stud is therefore supported rigidly against movement during the setting, and all danger of bending the stud out of shape during the setting is avoided.

The plunger J is mounted for vertical movement in the frame of the machine and is prevented from rotation byapin J, which enters a'groove J in the plunger. 7 The lower end of the plunger rests on a bearing-block J on the end of a lever J and is held against said block by a spring J". The lever J is operated to raise and lower the plunger by the disk D, which is eccentrically mounted on the shaft D and forms a cam for engaging a roll J on the end of the lever. The shaft D is operated from the driving-shaft D through gears D, connecting said shafts (Shown broken awayin Fig. l.) TheshaftD isdriven from the driving-pulley D through clutch mechanism similar to that shown in the patent referred to. When the operator presses the treadle L, the guard L is operated to release the clutch-pawl L so that it engages one of the teeth on the hub of pulley D and connectssaid pulley to the shaft D The shaft D is now rotated, and the guard is held in position by the annular rib L on the disk D until the shaft D has a made a revolution, when the notch in said rib registers engage the clutch-pawl, and roll Lenters the notchin rib L and holds the shaft D stationary until the operator again presses the treadle.

What I claim, and desire to secure by Lettors Patent, is-- therein, setting devices, means for transferring the studs from the plate to the setting devices, mechanism for operating the setting devices, a driving-pulley, means for connecting said mechanism with said pulley and automatically disconnecting it therefrom, a cam for operating said separating-plate, a frictiondisk connected with said cam to drive the same, and a friction-disk on the driving-pulley for driving said friction -disk, substantially as described.
