Patented Feb. 1, 1910.

Application filed February 6, 1909. Serial No. 476,393.

To all whom it may concern:-

Be it known that I, FERN L. CHENEY, a

citizen of the United States, residin at the city of Pawtucket, in the county Fromdence and State of Rhode Island, have invented certain new and useful Improve- 'ments in Machines for Setting Lacing- Hooks, of which the following is a specification, reference being had therein to the action is to provide a machine for this purpose that performs its work rapidly and accurately, feeds the hooks positively to the die or holder, and is simple and practical in construction. 7

In carrying out my invention I provide a positive means for feeding the quarters or work to be operatedupon, also simple and effective means for regulating'this' feed to vary the spacing in setting thehooks into the work.

Another feature of the invention is that} the table is fixed and that the riveter or anvil, as well as the holder or die, are both arranged to reciprocate vertically, said holder being carried down into alinement with the raceway to receive a hook at each stroke, which hook is positively fed to the said holder. I

The invention consists of other novel features and parts and combinations ofthe same as will .be fully described hereinafter and then pointed out in the appended claims.

A practical embodiment of the inveritibn is represented in the accompanying drawings, forming a art of this specification, in which similar 0 aracters of reference indicate coresponding parts in all the views.

In the accompanying drawings: Figure 1,.is a plan view of my improved machine showing a quarter dotted in position therein. Fig. 2.is a side elevation showing the frame partly. in section and illustrating the cam for imparting a forward and back reci rocating motion to the hook. feeding p ate. Fig. a 7 Ian view of the mechanism ilhistrated in ig."2, also showing the cam and connection for imparting longitudinal reciprocating motion to the hook feedin plate. Fig. 4.is a perspective view taken from the rearof the machine illustrating the hook feeding plate as withdrawn from the raceway,- which latter is shown as retaining the hooks preparatory to being fed one at a time to the holder, also showing the relative position of the holder when in its receiving position, the end of the anvil or'riveter 'showlng above. it. Fig. 5-sh0ws .a portion of the raceway with the adjustable stop spring in position to retain the hooks until they are en 'aged and moved positively along by the sai plate. Fig. 61s a cross section taken on line 66 of Fig. 4 of the raceway showing one of the hooks retained in the desired position by the friction of the thin spring plate. Fig. 7is a detail showing one of these thin spring plates. Fig. 8-is a top view of the hook holder or die. Fig. 9is a section on" line 9-9 of Fig. 8 showing the spring actuated hook retaining finger. Fig.'.10is a section on line 1010 of Fig. 8 illustrating the action of the spring on the pivoted hook retaining finger. F1g.-11 is a side elevation showing *the reciprocating riveting anvil and holder or die, and the cam and levers for operating the same. Fig. 12is a side elevation of the adjustable feed or spacing mechanism. Fig.

F i 14-'is a side elevation showing the feeding block and the levers which impart to the same the downward and longitudinal motions. Fig. 15is a detail illustrating the action of the main clutch member.v Fig. 16is a section on line 1.c 1 c of Fig. 14.

Referring to the drawings, 1 designates the frame of the machine which may be made in the shape of a yoke, or any other convenient form, and supported on suitable standards, not shgwn. The main driving shaft 2 is journaled'at 3-3 in this frame and receives its motion throu h the driving pulley 4, the hub of which pul ey is provided with teeth 5 forming a clutch to engage the corresponding teeth 6 in the slidable clutch member 7 when it is desired to connect said pulley to said shaft. This clutch member 7 is held in engagement with the opposite clutch member 5 by the pressure of a spring 8, see Fig. 15, and may be withdrawn from engagement with said clutch 5 by means of a lever 9 which may be released by a foot treadle, not shown, or any other suitable means to engagethe side bearing cam 10 on the clutch member to withdraw the same from engagement with the rotating pulley 4 to stop said shaft. In order to effect a positive and quick stopping of this shaft I have provided a brake bar 11 which is pivoted at 12, and has a roller 13 at one end which engages the cam 14, whereby the rotation of said cam causes the shoe 15 at the .opposite end of the lever to be set firmly against the periphery of the main cam disk 16 and prevent the mechanism from further action. This main cam disk 16 is fixed to the main shaft 2 and is provided with a groove 17, see Fig. 11, in one of its side faces for the purpose of imparting a vertically reciprocating motion to the hook holder or die 18, the shank 18 of which works in its bearing 23, said motion being imparted through the lever 19, which is pivoted to the frame at 20, one end of said lever engaging said cam at 21 and the opposite end engaging the lower end ofthe die shank at 22.

The anvil or riveter 25, which cotiperates and works in unison with the hook holder, is held to reciprocate vertically in its hearing 26, the same being ressed downward by means of the cam 24, on the periphery of the disk 16, through the lever 27, which is pivoted at 28, the riveter and the lever both being returned by means of the spring 29. The lower limit of the stroke of theanvil may be nicely regulated by means of the screw 27 which is threaded into the end of the lever 27 the collar of which is adapted to act upon the end of the shank 28 of the roll bearing 29*. 'After the same has been adjusted to the desired position in the lever 27 it is firmly gripped and retained by the set screw 30.

The hook holder or die 18, which is supported in the upper end of its shank 18 is provided with a flange portion 30 which is undercut at 31 for the purpose of receiving the head of the hook. This flange portion is rovided with a small hole 32' through which the point '33 of the riveting anvil 25 passes when the'riveter and the holder come together to fasten or rivet the hook into the work. This flange portion 30 is also pro vided with a small notch 34 which has a tendency to center or locate the hook in the proper position on the flange. In order to bind and secure thehook to this flange a movable finger 35 is pivoted at 36 to the face of the holder and is pressed with a flexible tension against the flange 30 by means of the coil spring 37.

.A table 38 is fixed tothe framework of the machine on a plane above the hook sup ply raceway, on which table the quarters, as shown in section at 39, are supported and manipulated while the hooks are being set i therein.

The bracket 40 secured to the frame at 41 supports a slidable plate 42 which is secured in the desired position therein by means of the thumb screw 48. This plate serves as a gage against which the edge of t the quarter is set when positioning the same in the machine.

A feed block 44, is provided to feed the quarters automatically forward at each withdrawing stroke of the rivet-er, said block being provided with teeth or corrugations 45 on its lower face, and is also provided with a dove-tailed groove 46 in its rear face to receive a correspondingly shaped portion on a supporting member 47 whereby said block may slide endwise there on. This said supporting member is provided with a square stem 48 extending upward and receiving a bearing in the framework, and a. spring 48 is arranged to hold said feed block normally out of engagement with the work. This supporting member 47 is also provided with a central hole 47 through which the riveting plunger 25 reciprocates. This feed block is arranged to be pressed downward at the proper time onto the work by means ofthe cam 49, see Fig. 1, through the lever 50, which is piv oted at 51 to the frame, the forward end of said lever being provided with an adjusting screw 52 adapted to engage the projection 53 on the supporting member whereby the pressure of said feed block upon the work may be nicely re ulatedQ In order to move this block 44 longitudinally to feed the quar ter forward toward the riveter at the proper time, a connecting rod 54 fulcrumed at 55 is forked at one end 56 to engage the pin 57 on the feed block. The opposite end of said connecting rod is moved back and forth in the guide-way 58, see Fig. 1, by means of the crank pin 59 through the connection 60. This crank pin is. fixed in the face of the gear 61 and is caused to rotate continuously and at the desired speed from the main shaft 2 through the gears 62, 63 and 64.

The number ofhooks, as well as the distance they are set apart in the uppers varies with the styles and sizes of the shoes, and therefore it is necessary to provide means for regulating the spacing of the hooks in the work. To accomplish this I have mounted the fulcrum 55 and connected the same to the lower end of the lever 65, which lever is pivoted at 66, the upper end being provided with a handle 67 for manipulating the same, and also with anoutwardly extending pointer 68, which when moved over the graduated are 69 indicates and controls the exact spacing of the hooks.

'In order to lock the lever and its fulcrum in' the desired. position a bolt 70 is passed through ablock 71 in a grooved plate 72 and a nut 73 is secured therein whereby a movement of the handle 74 will bind and hold the lever and fulcrum.

vide sufficient room for easy-.manipulation' of the quarter, I have provided a plate 75 fixed to the frame and having an upwardly projecting end iece 7 6 adapted to form the continuation o the raceway forthe reception of the hooks therefrom, as illustrated at 77 in Fig. 1. This plate is adapted to extend longitudinally along the front of the machine on a plane below that of the table 38, see Figs. 2 and 11. The underside of this plate is provided at intervals with thin fiat springs 78 78, see Figs. 4, 5 and 6, which are for the purpose of engaging the hooks 84 as they are fed along and retain them in position by friction when released by the feed plate to take another stroke. One end of these springs is set on an an 1e into the plate where they are secured y solder, rivets, or other suitable means, the free end pointing downward at a slight angle in the direction of travel of the hooks.

A spring finger 79, mounted on the frame 80, is secured by means of asorew 81 which extends through a slotted portion 82 therein, whereby this finger may be adjusted longitudinally. The free end of this finger is bent back as at 83 and is for the purpose of engaging the hooks as they descend from the raceway to retain them in the proper position 'to be engaged by the feed plate.

The hook feed plate 85 is provided on its front edge with a plurality of forwardly extending fingers 8683 which are adapted to engage the hooks and feed them along on the .plate 75 to the holder or die. This plate is fixed, by means ofscrews, to the movable bed 88, which bed is held. to slide longitudinally' on it's dove-tailed tongue 89 through the block 90, which block in turn'is adapted to be reciprocated forward and back in a similar groove inthe bed '91 guided by its dove-tailed tongue 92, said reci rocating-motion being imparted to the bloc by means of the cam 93, see Fig. 2, through the connec- -tion 9t. A cam 95 is provided to impart a longitudinally reciprocating motion to said hook feed plate through the lever 96 pivoted at 97, one end of which 98 engages said cam while the opposite end, which is forked at 99, engages a pin 100 in thebed 88.

The operation of my improved hook settin machine may be further described as folfows: The hooks are fed to the machine from any suitable hopper, not shown, down the usual raceway on which they are retained by the guard strip. In order to positively transfer these hooks from this raceway to the die or holder a reciprocating hook feed plate 85 is provided with a plu rality of fingers, each of which is adapted to engage one of the hooks that are held by the frictional springs on the hook supporting plate 75. At each forward stroke of the feed plate 85 the first finger thereon engages a fresh hook on the raceway, while the last finger, as the plate is fed longitudinally along, carries a hook into position on the hook holder 30, the under friction s rings 78 preventing the hooks from being ed too far at each rap-id stroke of the feed plate.

After the hook has been fed onto the holder both the die and the anvil are operated, bringing them both to ether on a line with the table 38 on which 1s held the quarter or work into which the hook is to be set, these two members meeting at this point forces the shank of the hook through the material and rivet it firmly on the upper side. The die and anvil are then at once removed and the stock is fed forward by means of the feed block 44, which block is brought down in contact with the oods by the action of the cam 49, and then ed forward longitudinally by the mechanism and crank m0tion-illus-- trated in Figs. 1 and 12. A presser foot 101 operated from the cam 102 through the lever 103 now engages the work, pressing and holding it securely against the table, while.

means of the crank motion, above described, .to take another bite to again feed the work forward.
