RIVET-SETTING MACHINE.
Application filed August 10, 1925. Serial No. 49,289.
This invention relates generally to the construction of rivet setting machines of a wellknown type which has gone into universal use and which has given satisfactory results. It has been found in practice, however, that certain details of the apparatus were unduly subject to wear or breakage and that there was a need for improvement in the operation of a rivet holding device which cooperated with the setting plunger. general ob'ect of the present invention is accordingly to provide an improved machine of the type referred to which will be free from the objectionable features pointed out and which, in general, will include features in the nature of improvements on the machine described in the prior application referred to.
The invention includes the provision of a replaceable wear and breakage-proof terminal member for a rivet supplying feedway with which the rivet setting plunger has close cooperative relation in operation.
Another feature of the invention resides in the mounting and method of operation of a rivet feeding spring member which operates to deliver rivets one at a time from the supply chute and to deposit the individual rivets in a rivet positioning and holding member for direct engagement by the rivet setting plunger.
Another feature of the invention resides in the mounting of a plunger stem for the rivet holding member referred to in a slideway located closely adjacent the path of travel of the rivet setting plunger so that a minimum amount of strain is placed on the connected parts in the operation of the rivet setting mechanism.
Still another feature of the invention resides in the provision of a clearing or guard member so arranged as to remove from a rivet feeding wheel such rivets as have remained in place in the wheel after passing the discharge point thereby preventing the jamming or clogging of the parts by misplaced rivet members.
Other features of the invention will be hereinafter referred to. 1

Figure 2 is a view in front elevation of the parts shown in Fi re 1.
Figure 3 is a view in side elevation of a port on of the device shown in Figure 1 look ng from the opposite side.
Figure 4 is a sectional view on an enlarged scale of a detail taken on the line 14 of Figure 2.
Figure 5 is a plan view on an enlar ed scale of a portion of a rivet feeding mec an1 sm forming part of the device shown in F1gures 1 and 2.
Figure 6 is a plan view of a rivet supply hopper and dehvery wheel forming part of the invention and shown on an enlarged scale.
Figure 7 is a view in vertical section of the parts shown in Figure 6.
Figure 8 is a view in front elevation of a rivet clearing device forming part of the structure shown in Figure 6.
lieferring to the drawings for a more detailed description of the invention, in Figure 1 is shown the head portion of a rivet setting mechanism which includes the upper aw member 10 on which the rivet setting parts are directly supported and a lower fixed aw member 11 which supports an adustable anvil member 12 against which the rivets are upset or clinched in the operation of the device.
One of the operating parts supported by the upper jaw member 10 consists of a rivet supply hopper 13 having a bracket member 14 formed integrally therewith for attachment to the forward extremity of the mem ber 10 by means of the screws 15. The supply hopper 13 directs rivets through a channel 16 into the interior of a cup-shaped rivet sorting and arranging member 17 which is mounted for rotation with a shaft 18 journaled in a bearing member 19 formed integrally with the hopper member 13. The rivet arranging member 17 is provided at its open edge with a series of rivet receiving slots 20 into which the rivets supplied from the passageway 16 find their way in the rotation of the member 17 and are arranged with their head portions occup ing a groove or channel 21 formed in the amework of the hopper at the junction thereof with the contiguous slotted edge of the cupshaped member 17.
In the operation of the device the cupshaped ember 17 is rotated and rrie h arranged rivets into a position to drop into a chute or feeding channel 22 which leads to rivet setting mechanism adjacent to the lower end of the chute. The rotation of the rivet sorting member 17 is brought about through the action of a pawl member 23 with a ratchet wheel 24 carried by the end of the shaft 18. The pawl 23 is carried at the end of an arm 24 and pivoted at 25 on the front bracket member 31. In order to oscillate the arm 24 and thereby actuate the pawl 23 an operating arm 26 is pivoted at 27 on an upstanding lug 28 and carries a forked member 29 which is oscillated about the pivotal point 27 to operatively engage a pin, 30 carried by the arm 24. The forward extremity of the bracket member 31 is provided with a guideway groove in which the operating lunger or arbor 32 is mounted for vertica ly reciprocating movement. The arbor is operated by a double link connection 33 between the upper extremity of the arbor and a forwardly projecting extension 34 of the operating arm 26. The lower end of the arbor 32 is arranged to receive and su port a rivet clinching or upsetting tool 35.
he rivet clinching tool 35 reciprocates in substantial contact with the lower extremity of the rivet feeding chute 22 already referred to. By this arrangement the clinch ing tool is located to immediately engage a rivet as it emerges from the lower end of the feedway.
In order to obviate the wear and possible breakage of the extremity of the chute o1 feedway 22 with which the riveting tool 35 enga es, provision is made for using a re inova 1e and replaceable wear piece 36 formed of suitably hardened steel or the like and which is held in place on the end of the fcedway in an suitable manner. The use of the replacea le wear piece as de scribed obviates the ossibility of injury or wear to the rivet feeding chute which would render necessary the discarding of the entire chute structure.
Another feature of the invention resides in the construction of a rivet holding device which su ports the rivet in the proper position for tie application thereto of the rivet clinching plun er 35. This structure includes a rivet ho lding member formed of two jaw-like members 37 supported on spring members 38 in order to permit the members 37 to spread apart to permit the passage therethrough of the rivet and the rivet setting tool 35. The spring members 38 which support the jaw portions 37 are held in position in grooves 39 formed in the opposite faces of a plunger 40 by means of a bolt and wing nut construction 41. The plunger 40 is mounted for reciprocation in a way located closely adjacent to the path of travel of. the arbor 32 in a forward portion of the bracket member 31. The
In order to bring about a direct application of the force of the spring to the plunger the spring is housed in a slot 48 in a face plate 49 so that the spring 45 lies in contiguous engagement with the side of the plunger 40 and thereby is effective to act on the plunger along its own length. A bridging member 50 connects the two sides of the face plate 49 and strengthens the parts.
Referring to Figures 6 and 7 of the drawing a rivet clearing member 51 is mounted on the face of the hopper 13 in a cutout por' tion 52 in close adjacency to the notched edge portion of the rivet sorting member 17. The rivet clearing member 51 is provided with an angularly extending wing member 53 which in the rotation of the member 17 engages such rivets as may have remained in the slots 20 after passing the entrance to the rivet feedway 22. The relative movement of the rivet with relation to the win" member 53 serves to force the rivets so engaged axially with relation to the member 17 and toward the outer ends of the slots. The other side of the member 51 has a downwardly projecting portion 54 which in turn engages the rivets which have been moved to the open edges of the slots 20 by the action of the wing member 53 and forces the rivets so engaged radially inward so that they drop clear from the slots and into the cupshaped member whereby they may be acted upon for a rearrangement in the slots 30.
In order to cause the cup-shaped member 17 to yield under a. jammin tion of the rivets, the cupfiaped member is held to its seat against the flange 55 on the shaft 18 by means of a spring member 56 which is engaged on its outer surface by a wing nut 57. It will be seen that the yield ing pressure of the spring 56 against the base of the cup member provides for slippage or yielding of the cup member under a jam that would otherwise tend to break parts of the mechanism. The wing nut 57 has a screw-threaded relation with the end ofthe shaft 18 at the end 58 as will be seen.
Another feature of the invention resides or clogging ac- I in the mounting and mode of operation of a rivet feeding spring member 60 which is formed in a laminated or leaf construction and engages at its lower or free end a slot 61 in a slide member 62 arranged to move rivets one at a time from the feed slideway 22 into a discharge slideway 63 from which they pass directly underneath the rivet settin plunger 35. a The spring 60 has an elongate formation and comprises a laminated or leaf structure as is clearly shown in Figure 1 of the drawing. The lower end of the spring is forked and enters the slot 61 in the slide or cut-off piece 62 in order to operate the same. The upper end of the spring 60 is held in a forked arm 64 forming a downward projection from the lever or arm 24 already referred to as mounted for pivotal movement about the center 25. With this construction it will be seen that movement of the arm 24 to correspond with the oscillations of the forked member 29 produces a corresponding movement of the spring member 60 to thereby move the slide or cut-off member 62 to and from its rivet delivering position.
What I claim is 1. In a rivet setting machine, a laterally extending jaw member, a reciprocable arbor mounted in said jaw member, rivet feeding mechanism mounted on said jaw member, a pivoted lever for moving said arbor, a forked member carried by said lever, a rocker arm for. operating said rivet feeding mechanism, said rocker arm carrying a part extending within said forked member.
,2. In a rivet setting machine having a laterally extending jaw member, a vertically reoiprocable arbor mounted for operation on the free end of the jaw member, a vertically extending chute along which rivets move to a position adjacent the operating position of the rivet setting member, a cut-off slide mounted for horizontal reciprocation in the lower portion of the chute, an elongated vertically-extending laminated spring member having its lower end in actuating engagement with the cut-off slide, a horizontally arranged lever mounted on the jaw member for rocking movement about a transverse axis, one end of said lever having a link connection with the upper end of the arbor to thereby operate the same, a vertically extending lever mounted for oscillation about a horizontal axis, the lower arm of said lever being longitudinally slotted to provide a seat for the upper end of the spring, a roller carried by the upper arm of said lever and a forked member carried by the horizontal lever for engaging said roller whereby the horizontal lever Wlll. serve to actuate the vertical lever.
In testimony whereof I aifix mfiasignature.
