To all whom it may concern: 1

Beit known that I, ARTHUR R. HAVENER,

a. citizenof the United States, residing at Wayland, inthe county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Feeding Mechanisms for Rivet and Cap Setting Machines, of whichthe following is a specification.

This invention relates to machines for feeding disk-shaped'articles such as the caps for rivets.

The object of the invention is to provide a rivet-cap feeding mechanism which is simpleand eflicient in action. j

The application is a division from the'app'lication of Arthur R. Havener, rivet and cap setting machine, Serial No. 220,193, filedMarch 4, 1918. c

.The' invention consists in a cap feeding mechanism hereinafter described in the specification and particularly pointed out in the claims. j "Referring to'thedrawingsgr V Figure 1 is a; left hand side elevation of a rivet cap setting machine with my 'improved cap feeding instrumentalities embodied, therein. 1

Fig. 2" is a longitudinal central section of said machine.

"Fig. 3 is a detail plan view of the rivet:

cap feeding instrumentalities. igs. 4.- and 5 are detail .plan views 'simllar to Fig.v 3 illustrating the cap feeding in strumentalities in differentpositions. a

Like numerals refer to like' parts' throughout the several views of the draWingS. In the drawings, 6 is the frame'of the machine, 7 is the anvil, 'Sthe work-support, 9

the rivet driver and 10 the rivet carrier.

11 and 12 are the horizontal and- "inclined portions, respectively, of a raceway 'l3 which feeds the rivet caps from a rivet cap hopper 14 to the'anvil 7.

'The' rivet caps are deposited in mass in' the hopper 14 and are fed from said hopper down the inclined portion 12 of the raceway 13 untilthe lowermost rivet'cap115 on said inclined portion 12 of the raceway rests against the upper edge of a slide as illustratedin Fig.3.

Arivet cap detent and feed finger 17 consists of an arm 18 which is pivoted at '19 to V the'frame of the-machine and terminate in as said slide is'moving anvinclined portion 20' at its forward end, said-inclinedportion'20 being adapted to be engaged'by the front edge of the slide 16 forward in a manner hereinafter described; A plate21 is fastened to the arm 18 and said plate hasalateral wedge-shaped proection 22 thereon which is adapted to enter between'the lowermost rivet cap 15 on the against' movement downwardly on the 'inclined portion of the raceway by the projection 22 on the plate 21.

oflto a pin 25 and at the other'end thereof to apin 26 bearing against the frame of the machine. Said pin 25 is fast to the arm 18 and constitutes a stop pin to limit the dis-- tanceto which the arm 18; can be 'moved by the spring 24, and when the parts are in the relative positions illustrated in-Fig. 3

the free end of the arm 18v rests against-the 'The raceway 13, consisting of the inclined portion 12 and the "horizontal pOrtionll, is

. A spring 24 is connected at one end there formedby two parallelly disposed members 27 a'nd 28 whichhave a space 29 therebetween. These

members

27 and 28 are each grooved at 30 and 31, respectively, upon their inner adjacent faces to receive the opposite sides' of the rivet caps as they are fed along the raceway. The raceway 13 terminates at'jlits front end in two.

fingers

32 and 33 pivoted zit-34c and 35, respectively, to

.the frame of the machine'and terminating'at their 5 front =ends' in segmental circularshaped recesses 36 and 37 into which" the rivet cap is fed when in its forward position by the slide-.16. j 'Thes'work-support 8 has aproject'ion 38 thereon-constituting a stop against which the finge'rs 32 and 33 abut-when in the position illustrated-in Fig. 3. Said fingers and 40,-. respectively.

[are moved tow'ard each other by springs 39 reciprocatory motion is imparted to the slide 16 by a bell-crank lever 41 which is pivoted at -12 to the frame of the machine and the vertical arm 1?) of which-engages anear d4: on the slide 16. The horizontal arm" of said bell-crank lever has a circular sha 36d end 15 which enters a slot 16 in a mein er 17. The member 47 constitutes a link, the upper end of which is connected by a pin 18 to a lever 49 and the lower end of which is mounted. upon a crank 50 formed on a shaft 51 journaled to rotate in the frame of the machine.

A rotary motion. is imparted tothe shaft 51 by a clutch 52 which is drivenfrom the main driving shaft of the machine. The ear 4A is held againstihe vertical arm 43 of the bell-crank lever 41 by a spring 54;

connected to the vertical arm i3 of the bellcrank lever 41 at one end thereof and at its opposite end 18 connected to anarm 55 wvhich is fastened tothe slide 16, so that the slide16=is carried forward by the spring 54: V

V motion imparted theretoby arlever 57- pivotedat 58 to the frame' of the machine and having a rocking movement imparted thereto bythe inclined lower edge 59 of the slide 16 which, in. its forward. .and backward movement, engages airoll .60 journaled on the rear end of the lever ,57.

The general operationof the cap. feeding mechanism hereinbefore described is as fol lows: Assumingthe shaft 51 to be. rotating in the direction of ithe arrow. a, Fig. 2, the bellcrank levers]. *will be-operated-to move the slide 16 rearwardly until thefront end of said slide disengages the free endof thearm'18 (see-Fig.3) and said arm will then be moved bythespring 24 to the position ill'ustratedin 'Fig. 4, withthewedga shaped projection22 projecting between and pressing against the lowermost-rivet cap 15 on the inclined portion 12 ofthe raceway 18 and against the next to-the lowermost rivet cap.'23'on saidracew-ay. The lower edge'of thelon' ermost rivet cap is now bearing against the upper edge of the slide 16.

Upon a further movementof'saidslideto ward the rear the upper edge ofsaid slide will become disengaged from the -rivet cap 15 and the spring 2 1 will then cause the arm18 tospring forwardly into theposition illustrated in Fig." 5 andthns drive the rivet cap 15 forward onto and along thehorizontal portion 11 of therivetcap raceway,

while at the same time the projection 22 holds the rivet cap 23 and the column of rivet capsabove the same against movement onthe rivet cap raceway. 7

During this rearward movement of the slide 16 the incline 59"o1rthe lower edge of said slide engages the roll 60 and rocks the lever 57 to raise the anvil 7 and at thesame time the lever 49. is: rockedto move the driver 9 downwardly and the rivet is set in the rivet cap in a manner'well known to those skilled in the art, but forming no part of this invention.

During the settingiofthe rivet in the rivet cap the anvil 7, during its upward and carries the rivet vcap, which at that time is held between said'fingers in the segmental recesses 36 and 37, upwardly and against the lower surface of the material to which the rivet and rivet cap: areto beattached.

After the rivet has been set the motions of the different parts hereinbefore.described will be reversech .that is, the rivet carrier and rivet driver. will be moved. upwardly, the anvil will move downwardl g the fingers 32. and 33will. be brought toward each other by their. respective springs until .they; engage" the stop; 38, .and the bellecrank lever 41 will be rocked to allow thesli'de 16 to be moved forward. by the spring 5 1 until j the front. end ofsaid slide 16 engages the i11- clined end 20015 the arm18 and pushessaid arm out ofthe raceway slot, whereupon the projection 22 willnbe removed from engage ment with..therivet cap 23 and said rivet .cap will then .sli'de.downthe inclined portion of the :.r.ivet cap raceway until its lower edge engages the upper edgexof the. slide 16. Meantime-the rivet-zcap ll'i which has been forced onto and along theihorizontal portion 11 of the raceway l 'will be engaged by the front end of the slidelG and fed for- WELFClZlJGtWGGlLthG: fingers 32Tand 33 .until it lodges in the segmental. circular recesses 36 and 87 on the frontend of saidjfingers anvil and therivet carrier 10. The slide 16 will then .be moved (back to the position. illustratedin. Fig. .2' and the operator will '80 movement, forces the vfingers82 and 33 apart.
