RIVET AND CAP SETTING MACHINE.

Specification of Letters Patent.

Patented Aug. 20, 1918.

Application filed March 4:, 1918. Serial No. 220,193.

To all whom it may concern: 1

Be it known that I, ARTHUR R. HAVENER, a citizen of the United States, residing at Wayland, in the county of. Middlesex and State of Massachusetts, have invented new and useful Improvements in Rivet and Cap Setting Machines, of which the following is a specification.

This invention relates to a machine for attaching articles to sheet material by means of rivets clenched in rivet caps. The machine is particularly adapted for use in riveting the clasps and hasps of buckles to raincoats, overshoes and other garments.

The object of the invention is to provide a light, simple and easily operated machine which can be moved around from one place to another in a shop with very little difiiculty and which will combine certainty and speed of operation with durability and strength.

The invention consists in the combinations of mechanisms hereinafter set forthand particularly pointed out in the claims whereby the rivet. feeding and setting instrumentalities and the cap feeding and setting instrumentalities are all operated from a single crank, eliminating all rotary cams and thus very much simplifying the machine as well as providing a machine which runs easily and noiselessly and with comparatively little wear on the difi'erentparts thereof.

The improved means whereby the rivet caps are separated one by one from a column of rivet caps on an inclined portion of the raceway and forced-onto and along a horizontal portion of said raceway and subsequently fed to the anvil is made the subject matter of a divisional application, filed by me on June 17, 1918, Serial No. 240,403. The clutch and rivet cap hopper, while being shown in the drawings and described in the specification, are each made the subject matter of a separate application for Letters Patent filed by me of even date herewith.

The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Flg. 13 is a sectional elevation taken on llne 13-13, Fig. 4.

14: is a plan view of a buckle hasp.

Llke numerals refer to like parts throughout the several views of the drawings.

In the drawings, 15 is the frame of the machine. 16 is the anvil, 17 the work-support, 18 the rivet driver and 19 the rivet carrier. 20 and 21 are the two parts constituting the rivet raceway which leads to the rivet carrier 19 from the rivet hopper 22. 23 and 24 are the horizontal and inclined portions of the raceway 25 which feeds the rlvet caps from a rivet cap hopper 26 to the anvil.

27 is the main driving shaft of the machine which is rotated by means of a pulley 28 to which is fastened a pinion 29 which meshes into a gear 30 rotatably mounted on the crank-shaft 31. The gear 30 constitutes vented from moving longitudinally upon the crank-shaft 31 by a collar 33 fast to the shaft 31 at one side of said driving member 30 and by thedriven member 32 on the opposite side of said driving member. The driving member 30 is provided with pins 3 1 which engage a dog 35 pivoted at 36 to the driven member 32 and thus rotate the crankshaft 31, (see Figs. 5 and 6).

When it is desired to rotate the crankshaft 31 to operate the machine, a slide 37 (Fig. 5) is moved toward the right in said figure to disengage the same from the dog in "l 85 by means of a bell crank lever 133 (Fig. 5) which engages a pin 13: fast to the slide 87 and is operated by means of a treadle rod 135 which leads to a treadle (not shown in the drawings). As soon as this occurs a spring follower 38 moves the dog out into the path of one of the pins 34-. The driving and driven members of the clutch are then looked together to rotate the crank-shaft 31.

A reciprocatory motion is imparted to the driver 18 by a' driver slide 39 which is connected by a pin all to a lever l1, (Fig. l). The lever 4-1 is pivoted on a pin is which is supported in an arm 43 which, in turn, is pivoted to an eccentric stud ll. The eccentric stud 44 has an arm 45 fast thereto by which it can be rotated and said arm has a spring actuated pin d6 slidably mounted in its outer end and adapted to project into any one of the holes at? in the segmental plate 49:, which segmental plate is fastened to the frame of the machine, so that by rotating the eccentric stud a l to different positions by means of the arm 45 the arm 4-8 is raised and lowered and consequently the pivot d2 of the lever ll is raised and lowered. (See l igs. d, 5 and 13).

The lever il is connected at its rear end by a pin ll) to a member 50 which, at its lower end, is mounted upon the crank 51 of the shaft 31.

The member 50 consists of two parts 52 and 53 having screw-threaded engagement with each other, whereby the length of said member 50 may be increased or diminished as desired. The part 52 is slotted at 5% to receive the circular shaped end 55 of a bell crank lever 56 which is pivoted at 5'? to the frame of the machine and the vertical arm 58 of which engages an ear 59 on a slide 60.

The slide 60 is provided with an inclined lower edge 61 which engages a roll 62 journaled upon a lever 63 which is pivoted at 64 to the frame of the machine, and ternii nates in a circular shaped end 65 which projects into a slot 66 extending transversely of the anvil 16. Said anvil is arranged to slide vertically in a sleeve 67 fast to the frame of the machine.

The ear 59 is held against the vertical arm 58 of the bell crank lever 56 by a spring 68 which is connected to an arm 69 fast to the slide 60, so that the slide 60 is carried forward by the spring 68 and backward by the arm 58. The distance to which the slide 60 can be moved forward is limited by a screw 70 which, when the slide has arrived at its extreme forward movement, engages the frame of the machine.

The rivet caps are deposited in mass in a hopper 26 and are fed from said hopper down the inclined portion 2a of the raceway 25 until the lowermost rivet cap 72 on said inclined portion 2% rests against the upper edge of the slide 6, as illustrated in Fig. 10.

A rivet cap detent and feed finger 73 consists of an arm it which is pivoted at 75 to the frame of the machine and terminates in an inclined portion 7 6 at its forward end, said inclined portion 76 being adapted to be engaged by the front edge of the slide 60 as said slide is moved forward.

A plate 77 is fastened to the arm n and said plate has a lateral wedge-shaped pro jection 78 thereon which is adapted to enter between the lowermost rivet cap 72 on the raceway 25 and the neat to the lowermost rivet cap 79 on said raceway, so that said projection 3'8 acts as a wedge to force the cap 72 from the inclined portion of the raceway along the horizontal portion thereof after the slide 60 has retreated sufficiently to allow this to be done, as hereinafter more fully described, and at the same time the to the lowermost rivet cap 79 is held against movement downwardly on the inclined portion of the raceway by the projection 78 on the plate 77.

A spring 80 is connected at one end thereof to a pin 81 and at the other end thereof to a pin 82 bearing against the frame of the machine. Said pin 81 constitutes a stop pin to limit the distance to which the arm '73 can be moved by the spring 80 and when the parts are in the relative positions illustrated in 10 the free end of the arm 74 rests against the side of the slide 60.

The raceway 25 consists of an inclined portion 2%, and a horizontally disposed portion 23 formed by two parallelly disposed members 83 and 84- which have a space 85 therebetween. These members 83 and 8% are each grooved at 86 and 87, respectively, upon their inner adjacent faces to receive the opposits sides of the rivet caps as they are fed along the raceway. The raceway 25 terminates at its front end in two fingers 88 and 89 pivoted at90 and 91, respectively, to the frame of the machine, and terminating at their front ends in segmental circular shaped recesses 92 and 93 into which the rivet cap is fed when in its forward position by the slide 60. V 4

The work-support 1'? has a projection 94: thereon, constituting a stop, against which the fingers 88 and 89 abut when in the position illustrated in Fig. 10. Said lingers are moved toward each other by springs 95 and 96, respectively.

The rivet carrier 19 consists of two jaws 97 and 98 supported by springs 99 and 100 from a slide 101. The jaws 97 and 98 are recessed to form a pocket 102 adapted to receive a rivet and hold it suspended by the head thereof in a manner well known to those skilled in this art. The slide 101 has a reciprocatory motion imparted thereto by a lever 103 pivoted at lO-lto the frame of the machine. The front end of the lever has a pin 105 fast thereto and connected by till lllll navaeea a roll 112 (see Fig. which is journaled to rotate upon a pin 113 fast to a downwardly depending arm 114, said arm being clamped to the part 53 of the member 50.

Thu a reciprocatory motion is imparted to the slide 101 and the rivet carrier 19. The distance to which the slide 101 can be moved 1 downwardly by the lever 103 is regulated by a stop screw 124 which is arranged to a u t against the frame of the machine when .the slide 101 isin its lowermost position,

it being understood that the lower edges of the jaws 97 and 98 of the carrier 19 are intended to stop when in their lowermost position very slightly above the upper surface of the buckle hasp which is being riveted to the sheet material. The extent to which said slide 101 can be moved upwardly is Y regulated by a stop pin 129 fastened to the slide 101 and adapted to engage a stop screw 130 (Figs. 1 and 2) when the slide 101 is in its uppermost position. The lever 103 at its rear end is provided with an upwardly extending arm 131 which is connected by a spring 132 to the pin 113 upon which the roll 112 is journaled, so that after the pin 129 in the slidelOl engages the stop 130, if there is any further downward movement of the roll 112 and the pin 113 the spring 132 will yield, and on the other hand at the end of the downward movement of the slide 101, if there is any further downward movement of the lever 103 at its forward end the spring 106 will yield.

Referring, now, to Figs. 1, 2 and 3, the hopper 22 has a rotary member 115 to which a rotary motion is imparted by a pulley 116, a belt 117 and a pulley 1l8 formed by a groove in the hub of the driven member '32 of the clutch 'and the rivets are separated and fed one by one from the part 20 of the raceway to the part 21 by a slide 119 which I i operated by a lever 120 pivoted at 142 to the frame of the machine, said lever having a pin 143 extending laterally therefrom to which one end of a spring 121 is attached, the other end of said spring, which is shown broken in Fig. 3, being attached to the slide 119. The pin 143 abuts against the right hand end of the slide 119 (Fig. 3) and a spring 144 is connected at one end to the lever 120 and at the other end to the frame of the machine (Fig. 2). I

The lever 120 is rocked b said spring 144 in one direction and is roc ed in the opposite direction by a pin 123 which is fastened to the lever 103 and engages a cam plate (Fig. 3) to feed a rivet from I It will thus be seen that should any obstruction to the movement of the slide 119 occur the slide will stop as it is moved yield- 1ngly in one direction through the spring iii and n the other direction by the spring The rivets pass down the part 21 of the rivet raceway and into the pocket 102 in the rivet carrier 19 ready to be ,insertedin the goods. The rivet caps are fed from the hopper 26 to the raceway 25 by mechanism forming the subject matter of one of the applications hereinbefore referred to, and said mechanism is operated by a shaft 125 draw? pg7adpulleyb126 which is rotated by a e riven a ulle 128 fast 0 the shaft 27. y p y t The general operation of the machine hereinbefore specifically described is as follows: The rivets are placed in mass in the hopper 22, the rivets caps are placed in mass in the hopper 26 and assuming the different parts of the machine to be in the relative positions illustrated in the general views of the drawingsand in Fig. 10 and that a rivet 130 has been fed into the rivet carrier 19 and a rivet cap 140 has been fed over the anvil 16, as illustrated in Fig. 4 in a manner hereinafter more fully described, the operator places the material 137 on the work-support 17 and holds the buckle hasp 138 up against the lower end of rivet carrier 19,

with the in said buckle hasp. He then throws the clutch into operation by operating the treadle to move the rod 135 (Fig. 5) downwardly, thus rocking the bell crank lever 133 and, through the pin 134, moving the clutch slide 37 toward the right, thus disengaging the left hand end of the clutch slide 37 from the dog 35. The spring follower 38 then causes the dog 35 to be moved to the position illustrated in Fig. 6 and said dog is then engaged by one of the pins 34 on the driving member 30, and the driving member moving in the direction of the arrow at (Fig. 6) causes the driven member 32 to be driven in the same direction and to thusrotate the crank shaft 31. v

The crank shaft 31, rotating in the direction of the arrow 6 (Fig. 4) causes the bell crank lever 58 to move the slide 60 rearwardly until the front end of said slide disengages the free end of the arm 74 (see Fig. 10) and said arm will then be moved by the at as? K spring 80 to the position illustrated in Fig, 11, with the wedge-shaped projection Y 8 projecting between and pressing against the lowermost rivet cap '12 on the inclined portion 2% of the raceway and against the next to the lowermost cap 7 9 on said race way. The lower edge of the lowermost rivet cap 72 is now bearing against the upper edge of the slide 60. Upon a further movement of said slide 60 toward the rear the upper edge of said slide will become disengaged from the rivet cap 72 and the spring 80 will then cause the arm 7 1 to spring forwardly into the position illustrated in Fig. 12 and thus drive the rivet cap 72 forward onto and along the horizontal portion 23 of the rivet cap raceway, while at the same time the projection 78 holds the rivet cap 79and the column of rivet caps above the same against movement on the rivet cap raceway.

During this rearward movement of the slide 60 the incline 61 on the lower edge of said slide engages the roll 62 and rocks the lever 63 to raise the anvil 16 from the position illustrated in Figs. 1- and 7 to that illustrated in Fig. 8, and at thesame time the member rocks the lever 1-1 to move the driver slide 89 and driver 18 downwardly and simultaneously the arm 11: with the roll 112 rocks the lever 108 to move the carrier slide 101 and the carrier 19 downwardly until the stop screw 1A engages the frame 15, whereupon further downward movement of the carrier will cease, and the driver will continue its downward movement. The anvil has now been moving upwardly from the position illustrated in Fig. 7 to the position illustrated in Fig. 8 and has forced the ingers 88 and 89 apart and carried the rivet cap 140 with it upwardly and against the lower surface of the material 18'? to which the buckle hasp 138 is to be attached. The parts are nowin the position illustrated in l l 8.

l lpon further downward movement of the driver 18, the rivet is driven through the buckle hasp 138 and through the material 187 and its points entered inthe rivet cap 1&0 and clenched therein, as illustrated in Fig. 9. At this point in the series of operations the crank 51 is in its uppermost position and upon further rotation of the shaft 31 it will commence to move downwardly and the motions of the different parts hereinbefore described will be reversed, that is, the rivet carrier and rivet driver will move upwardly, the anvil will move downwardly, the fingers 88 and 89 will be brought toward each other by their respective springs until they engage the stop or and the bell crank lever 58 will be rocked to allow the slide 60 to be moved forward by the spring 68 until the front end of said slide 60 engages the inclined end 76 of the arm '14 and pushes said arm out the raceway slot, whereupon the projection 778 will be removed from engagement with the rivet cap 79 and said rivet cap will then slide down the inclined portlon of the rivet cap raceway until its lower edge engages the upper edge of the slide 60. Meantime, the rivet cap 72 which has been forced onto and along the horizontal portion 258 or the raceway 25, will be engaged by the front end of the slide 60 and fed forward .cetween the fingers 88 and 89 until it lodges in the se mental circular recesses 9:2 and 93 on the front end of the fingers 88 and 89 and in almement with and between the anvil 16 the driver 18 and the rivet carrier 19. a

The slide 80 will then be moved back to the position illustrated in Fig. 1 and the operator having released the treadle. the dog 3o will engage the slide 87 and be thrown out of engagement with the driving member of the clutch, whereupon the machine will come to a stop. The buckle hasp is then moved, by the operator, together with the material, to insert a rivet in the other hole 141 thereof in the same manner as hereinberore described in relation to the insertion of a rivet in the hole 1-10.

desired, instead of placing the material 13; on the work-support 17 and holding the puclrle haSp 188 up against the lower end of LhB rivet carrier 19, with the rivet 136 projecting into one of the holes 189 in said.

buckle hasp at the beginning of the operation of the machine, the operator may place the buckle hasp 188 against the material 187 and hold them up together against the lower end ofthc rivet carrier, with the rivet 186 projecting into one of the holes 189 in said buckle hasp. Then, when the machine is operated as hereinbefore described, the carrier 19 will move downwardly until the stopscrew 12% engages the frame 15 and the parts, together with the buckle hasp and material, assume the relative positions illustrated in Fig. 8, whereupon further downward movement of the carrier will cease and the driver will continue its downward movement to drive the rivet through the buckle hasp and material and clench it in the rivet cap, as illustrated in Fig. 9.
