To all whom it may concern: Be it known that 1, JAMES E. Amusing a I citizen of the United States, residing tat Chico, in the county of Butte and State pf California, have invented certain new and useful Improvements in Apparatus for Riveting Cloth, Leather, and Similar Material, of whi h the following is a spdcification. i

The hereinafter described invention relates to an apparatus for the securingjof rivets in cloth, belting, and other 'pliagble materiahbut more particularly in the se curing of rivets in connection with the wink of manufacturing riveted overallsand liarness. work; the object of the invention being to dispose of the hand work at present employed for puncturing the cloth or inaterial to be riveted, placing the rivets therethrough, and securing the-same by upsetrivet stem after the placing of a washer work of riveting, materially reducing the costincident to such riveting and facilitating the work there'f, and increasing the factory output of riveted material of the character described.

To comprehend the invention reference should be had to the accompanying sheets of drawings, wherein- Figure'l is a sectional side elev'ationof the improved apparatus. Fig. 2 is a broken top plan view of the mechanism disclosed by Fig. 1 of the drawings.

Fig. 11 is an enlarged broken detail sectional view disclosing the 'mechanism for feeding forwardly the washers for the riv ets. Fig l2 is a broken detail plan view of the devices illustrated by Fig. 11 of the drawings. Fig. 13 is an enlarged broken detail view illustrating the material in position to receive a rivet a rivet placed there through, a washer fitted to the stem thereof, and the actuating parts in position for upsetting the stem of the rivet. Figs. i l, 15, and 16 are detail views of two of the actuating cams and the rolls working in theirregular grooves thereof.

In the drawings, the numeral 1 is used to designate any suitable form of a hollow supporting base. casting for the apparatus, from which springs an upwardly ex tended forwardly pro ected bracket arm 2. Through the base casting is extended an operating shaft 3, which is. driven by a 5 working over a drive pulleyA, loosely mounted on the projecting end ofthe operating shaft 3, Fig; 1 of the drawings This drive pulley is placed into and out of locked engagement-with the op- .erating shaft 3 by means of the cam clutch 'shoe' 5, pivot end of the arm 5,

d at its inner end to the upper which arm is keyed to the operating-shaft 3. This shoe is located to frictionally engage the under face of the rim of the drive pulley 4, and the outer end thereof is held normall against the face of the pulleys rim by the spring held plunger 5 which works throu h an ear 5 project- I a l mg from the arm 5, and 1s held outwardly by the pressure of the spring 5, Fig. 8 of the drawings. On a downward movement of the foot treadle 6, which is connected to a crank arm 7, projecting from a rock shalft t 1e held clutch rod'9, Figs, 1 and 3 of the drawings. As this plunger rod is retracted,

the free end of which normally lies within the pathof the clutch cam shoe 5, the shoe 5 is released and forced into frictional engagement with the drive pulley 4, for transmitting its rotation to the operating shaft manner mentioned, the cloth or material will be described in the order named,

While these erate successively and in the action of each is so.

various parts 0 the order name, I quickly accomplished that to all intent and purpose they' seemingly operate simultaneously.

For a clear understanding of the Working of the various parts of the apparatus, each presuming the operating shaft to be held locked to the drive pulley, for the various mentioned parts perform successively the work required thereof during one, complete reVo-' lution of the said drive pulley."

To, a post 2 upwardly projected from the overhang portion of the bracket arm 2 is fulcrumed an operating lever, comprising a an independently; fulcrumed extension member 12, fulcrumed respectively at the points 2 and 2 The withinthe forked or bifurcated outerend ll of the member 11 by means of. a securing pin 12, which extends through a slotted portion of slldably mounted in the slotted portions of Figs. 3 and f 55.

v above and parallel with the said member 11, Figs. land 2 of the drawings. This adjustable operating lever,

operates respectively the plunger rod 13, carrying at its lower end the puncturing awl 13, and the each of which extend through and are held .Within'thehead -14, slidably mounted with in the outer enlarged end :the drawings. The said slide head is m'oved'outwardly' and inwardly for alining the puncturing awl l3 and the rivet jaw plunger rod 13 with the awl opening'l5 in the anvil block15, F i 1 of'the drawings,'fitte d in the bed 'sur ace 16 of the base casting 1, by means of'the rock shaft 16,'- which shaft is'arranged the operating-shaft 3. From the outer end'of said rock shaft 16f projects a slotted crank arm 17, within which arm works a stud 1 7 projecting from .raise and lower the link connection 18 extenslon member 12 is held.

the member 12 and blocks 12" Fig. 9 of the drawings,

'rivet jaw plunger rod13'li' one face of the slide head 14, so as to move the said slide head in accordance with the in one face of the 'cam l( and which roll asit travels within said groove 20. serves to lever arm 19 and its to the rock shaft 16, for actuating the same to throw the crank arm 17 for imparting an outward and inward movement to the slide head 14.

From the inner end of the adjustable operating lever fulcrumed to the overhang of the bracket 2, depends the drawings, lever arm 22, hinged to the base of the machine at'an opposite side to that at which the lever arm '19 is pivoted, and, like said arm 19 thelever arm 22 carries a roll 22,

which works within an irregular groove 23,

out in the opposite face of the cam 10 to that in which the groove 20 is formed. The said irregular grooves 20 and 23 cut in the opposite faces of the cam 10 are so disposed relative to each other as to properly time the actions of the respective lever arms 19 and 22, for transmitting motion to the describedparts con trolled thereby, it being understood that as the roll 22 works within the irregular groove 23 it acts to raise and lower the inner end of the fulcrumed op erating lever for timing and regulating the movement of the puncturing consistin of twmsegm'enta'l clamp plates 23 and 23, which, when brought together, form a mutilated clamp ring, the section removed from the clamp plates-providing an opening 24, said clamp jaw straddling the lower in ,wardly curved extension 24 of the rivet runway 25 for the rivets 25, Figs. 5 and 6 of the drawing From the respective sections of the clamp jaw curvedjarms 26 and 26, which are united roll- 19, which roll a link 21, Fig. l of which link is pivoted to a I awl and the rivet receiving and placing mechanism.

. The rivet receivingand placing mechanism comprises a clamp jaw which permits of the i project the crossed by the pivotal pin 27,the free ends thereof.

being connected and normally held together -by means ofth'e spring connection 27: The

pivotal pin 27 extends through a vertical slot 2-8'formed in the .lower reduced'end portion of the rivet jaw plunger rod 13', which rod is straddled by These arms are forced apart during the inwardinovement of the slide head 14, to open the clamp jaw for receiving the rivets 25',

the arms 26 and 26. A

by meansof the cam lingers 28" and 28 secured to the under face of the portion 29- of the overhang portion of the bracket 2, the free ends of said cam'fingers passing respectively between the inner. faces of the arms 26 and 26 and the adjustable screw studs 30 and 30 projecting from the-outer faces of the slide head 14, the outer-crossed extensions 30 and 30 being pivoted at 28 and united by the springconnection 30, Figs. 3, G and 10 of the drawings.

The connection between' the clamp aw and the plunger rod 13 is a loose one, so

that when the clamp jaw bears onto or against the material into the punctured opening of which the rivet is to be inserted, the plunger rod 13 which bears against the head of the held rivet, may continue its downward movement to the extent of th length of the slot 28 therein, Fig. 9 of the drawings, so as to force the rivet 25' from within the cup seat of the clamp jaw and positively force the stem thereof through the perforated material to be riveted. Norsure thereon to permit of its ready removal from within the curved extension of the slotted rivet runway 25, such pressureis a slight one andisreadily. overcome by the downward pressure exerted on the head of the rivet by the plunger rod 13, which forces the rivet from within the clamp, the same giving to such pressure and allowing the held rivet'to be forced from within the clamp.

The rivets are placed within a cylindrical container 31, mounted for rotation on a stud 32. upwardly projecting from a fixed late 32, secured at an inclinatiomto the Jase of the apparatus, being supported by a bracket 33, Figs. 3, 5 and 6 of the drawings. This supporting plate or disk 32 is formed with a discharged opening 33,-;- situated 'im: mediately over the slot of the rivet runway 25, and'through which the rivets 25 pass. The bottom of the rivet container 31 is formed with a series of peripheral T-shaped outlets 3 1, through which the rivets escape lnto'the discharge opening 33 of the stationary plate or disk.32' when eithero-f the container outlets. 34 register therewith.

prises two spaced strips, the-stem of. the

rivets extended through the slot of the runway and the head thereof riding or resting on the upper surface of the said runway, the rivets moving downwardly by gravity until seated on the curved extension 24. The diameter of the rivet head is. slightly greater than the width of the runway and the head projects beyond 'the side edges thereof, so the same is readily clamped be:

tween the jaws of the rivet clamp when closed thereon.'

Rotation is imparted to the container 31 by the, drive belt 35, which works over the face of the wall of the said container and i the pulley 35 on theoperating shaft, the said belt passing over the tension rolls 36, Fig. 3 of the drawings. 7

The washers. for the rivets are held within the feed'tube 3 6,- -which extends through the bed plate ofthe machine and'communicates'with the slotted guide way 37 immediately beneaththe bed plate, Figs. 6, 11 and 12 of the drawings. Within this guide way -works a longitudinally reciprocating feed slide 37, the forward end of which is formed with a semi-circular seat 38 which embraces the lowermost rivet washer '38 of i the stack .of rivet washers held within the feed tube 36, which rivet washers rests in .rivet washers in depth is. substantially that of the thickness of a washer, so that a single washer fills the same.

From the slide 37" depends a stud which extends and works below'the slotted portion 39" of the guide-way-37, and the said stud is connected by a link 40 to the endof the lever 40, the opposite end of which is secured to a vertical shaft 4.1, to the lower end of which is secured ashort arm 12, which, in turn is connected to one end of a horizontal lever 42', the opposite end, of which is pivoted to the vertical lever 12*, carrying roller 42, working within an irregular groove 43 cut in the outer face of the cam 10', the upper end of lever 4 a be- .ing pivoted to'a bearing under the face of slide 37 which, on its outward movement removes the lowermost rivet washer 38;

from the stack of washers and carries the' same forwardly t0 the end of the slides v lifted by the rod 44:, after which the slide 37' begins its return stroke. However, on the forward stroke ofthe said slide 37 it is required that the washers be held in the feed tube 36' or in other wordsthatthe same. On the inward movement of the said 1 tube 36 on the return or inward stroke slide, the follower 44 is forced inwardly, compressing the spring 45 so as to act thereon for forcing the same outwardly on the next forward stroke of the slide 37. The moment the forward end of-the slide has passed beyond the discharge end ofthe feed thereof, the stack of retained rivet washers lower by gravity to place a washer within the guide-way 37 in advance of the slide 37.

The rivet washer is forced upwardly into the awl opening 15 of the anvil block 15 and onto the stem of the' rivet extended therein by means of the tubular rod 44, which by a yoke connect-ion 45 is connected to the free end of .a pivoted lever arm 46, Figs. 11 and 13 of the drawings. This lever arm carries a roll 46 which works within an irregular shaped groove 47 cut 'in the inner face of the cam 10 so that as the-said cam is rotated the lever arm 46 is swung up and down. As thrown upwardly, it

raises the washer holding rod 44 to place the washer held thereby onto the stem of the rivet, inwhich position it is maintained until the projecting end of the rivet has been upset or headed.

The upsetting of the rivet stem is accomplished by a series of impact blows givenunto the loosely held hammer stem 47, which works through the tubular rod 44, the lower end thereof. resting upon the hammer head .47" secured to and carried by thefree end of acoiled spring 48, Fig, 6 of the drawings.

The opposite end of this spring is attached to acrock shaft 48, from which shaft projects an arm 49 carrying a roll 49. :This roll workswvithin a groove 50 in the face of the cam 10 opposite to that containing the irregulargroove 47 Fig. 10f the drawings, and the said groove 50 is formed with the angle sections a, b, 0, Fig. 7 of the drawings, [as the roll rides outward on angle portion a thearm 49 is' thrown to actuate the rockshaft 48 to wind the spring 48 and place the same in tension, the outer end of said spring being held against movement by the pivoted dog 50- which bears thereon, the upper end of the dog being drawn inwardly by the spring 51, but held in proper position by the pawl 52, the position of which may be varied by the adjusting screw 53, Figs. 6 and 7 of the drawings. As the rock-shaft 48 is turned, the outer end portion of the spring 48 is radually curved or bowed by restraining influence of the dog 50 to hold the same against upward movement, so that by the time the roll 49 has passed the apex of the angle section a of the grooves 50, the

'innerfree end 53 of the spring 48 will have been depressed by the bowing or arching thereof to clear the dog 50, Fig. 6 ofthe drawings, when the torsional strain of the spring 48 will exert itself and the free inner end thereof be suddenly thrown upwardly under heavy pressure, which, carrying the hammer stem 47 .therewith causes the upper end thereof to strike against the lower end has cleared the lower end of the dog 50,

the same springs inwardlyto bear onto'the upper surface thereof. The described operation takes place as the roll 49 works over the sections b and c, of the cam groove 50, thus imparting three successive impact blows onto the hammer stemfor upsetting or heading of the projecting end of the rivets stem, the rivet 25 being held down during such action by the plunger rod 13.-

The heading or upsetting of the rivets stem completes the operation of riveting, when the described parts are again thrown successively into action for the puncturing of the material to be riveted, applying a rivet thereto, av washer on the stem. of the rivet and upsetting or heading the stem thereof. l

Inasmuch as considerable force is required to extract the awl 13 from within the mate- .rail 52 resting on the anvil block 15' after puncturing the same, the upper end of the plunger rod '13 for the awl 13 is cutaway as shown at 13", Fig. 6 of the drawings, so

that as the member 12 is thrown upwardly, the same engages the under surface of the end 13" and forcibly lifts the said plunger rod 13 to withdraw the awl 13 carried thereby from within the material 52".

The operation of the apparatus may briefly described as follows :'As the foot treadle is depressed the clutch or stop rod 9 is withdrawn from engagement with the hinged cam shoe 5, when the pressure of the spring 5" forces the same upwardly and into frictional engagement with the drive pulley 4, thereby imparting the rotation of said pulley to the operating shaft 3. During the rotation of the operating shaft, the cam disk 10 first acts to actuate therock shaft 16 to throw the slide-head 14 for positionin-g'the awl 13 in alinement with the opening. 15 of the drive-pulley.

may be made in' the construction of the dethe anvil 15, when the operating lever, com-' prising the members 11 and 12, is thrown to" act against the plunger rod 13 to'lower theand 13 and cause the same to puncture-the material 52 to be riveted. The said plunger rod 13 being then raised to withdraw the awl 13. when the rock shaft'lG operates to throw the slide-head 14 to place ,the 'r ivet clamp in alinement with the openin 15 of the anvil block 15', which clamp as received a-rivet 25 from th runway25i. A second strokei'sthen givento the mentioned operating lever, which lowersthe plunger rod 13' to place the stemof the rivet 25 through the punctured material 52, .after which 'the'jcam disk 10'. acts to throw the washer, feed slide 37 'to place a rivet washer operating shaft 3 will have made one com-- plete revolution, when, pressure having been released on the. treadle 6, the cam shoe 5 will. be engaged by the projecting end of the rod 9' and swung downwardly, and out of frictional engagement with the drive 'pu1ley,-'thus releasing the operating shaft and bringing-the various wor ing parts to a state of rest. The material 52is then ads 'vanccd on the anvi-lblock-15, to position the b same-t0 receive another rivet, when the foot mechanism placed intooperation, the parts treadle 6 is depressed and the described acting successively during one revolution of It is obvious that-various minor changes scribed working parts without departing from the spirit-of the invention, whlch consists in the providing of means forautomatically puncturing the material to be riv eted, inserting a rivet therethrough, applying a washer to the projecting ste'm of-the rivet, and finally upsetting the said stem;
