Taylor, Jack son, Mich., assî'gnors to Tomkins-Johnson Com pany, Jackson, Mich., a corporation of Michi gan Original application February 28, 1938, Serial No. 192,946, now Patent No. 2,360,991, dated Octo ber 24, 1944. Divided and this application March 6, 1944, Serial No. 525,170 1 Claim. (Cl. 'X8-48) 2 l This application is a division of our application Serial No. 192,946, ñled February 28, 1938, now Patent No. 2,360,991, granted October 24, 1944, and relates to riveting machines and the like, and more particularly to such a machine having a movable anvil. , In riveting it is often desirable to dispose a rivet or other upsettable member in supported relation to an anvil so that the work may be dis posed over the upsettable member and the up settable member headed up. Numerous struc tures have been developed for automatically pre senting an upsettable member in such a manner that the Work may be placed over the same and the upsettable member immediately upset. Var ious difficulties have been met, such as the use of too many moving parts for economic manufac ture or operation or the use of structures which do not lrigidly support an upsettable member for receiving the work and being acted upon by the set. ’I'he present invention contemplates the use of a movable anvil which may be alternately moved from a position in alignment with the up settable member feedingr means to a position in receive an upsettable member 63. The upsettable member 63 is supported in position on the top of the anvil 6I by jaws 64. The jaws 64 are pro vided with shank portions 65, which are secured by screws 66 to blocks 61 secured to the anvil'by screws 68. The spring metal Shanks 65 are pro vided with Va set, which urges the jaws 64 against the sides of the anvil 60 and at the same time against the upsettable member 63, which is dis posed between the jaws 64. Leaf springs 69 are also secured by the screws 66 to the blocks 61 to reinforce the action of the Shanks 65. The anvil 60 is reciprocated by a rod 14, which is operated by a suitable power source but pref erably by a piston and cylinder provided with con trols such as disclosed in the patent issued to Rob ert C. Hoyt, No. 2,176,008, granted October 10, 1939. LeftWard movement of the anvil 60, as viewed in Fig. 1, is limited by a shoulder 15 engag 20 ing with a plate 16 secured to the base 6l. Upsettable members are fed from a suitable hopper similar to the hopper I8 disclosed in our aforesaid application, Serial No. 192,946, to an in clined chute 11. Upsettable members in the chute co-operating relation With the set and back again. 11 are held near the lower` end thereof by a nose An object of the invention is to provide a riv eting machine or the like having an anvil which 18 comprising a portion of selector mechanism 19. The selector mechanism 19 comprises, in ad dition to the nose 18, a stop 80, and is slidable in a horizontal channel 8l in the inclined face of the is laterally movable with respect to the set. Another object of the invention is to provide a riveting machine or the 1ike having a movable an vil arranged to clamp therein an upsettable mem ber which presents the same beneath the set for being acted upon thereby. A still further object of the invention is to pro vide a riveting machine or the like having an an supporting block 82. It will be observed from Fig. 2 that the nose 18 and the stop 80 of the selector 19 overlie the chute 11, the latter being secured to the supporting block 82, while it is the lower portion of the se lector 19 which is disposed in the channel 8|. vil moving from a station for presenting an up settable member to the anvil, to a second station The selector 19 is normally urged to the right, the following specification When taken from the accompanying drawing,I in which in the path of the stop 86 for engagement thereby Fig. 1 is a partial vertical section of the pres ent invention, Fig. 2 is a partial plan view of the invention the leaf spring 83 against the opposite side of as viewed in Figs. 1 and 2, by a cantilever leaf in operative relation with the rivet set, together spring 83 secured to a frame portion 84 and dis with means controlled by the anvil moving means posed in a slot 85 in the selector 19, Movement for controlling the feeding of the upsettable mem 40 of the selector 19 to the left is provided by a stop 36 secured to and projecting upwardly from the bers to the anvil. These and other objects will be apparent from rod 14. The free end of the spring 83 is disposed when the anvil 69 is moved to the left to move the slot 85 and thus to move the selector 19 to the left. disclosed in Fig. 1, and As shown in Figs. 1 and 2, there is an upset table member 63 on the anvil 60 in co-operating Fig. 3 is a section on line III-III of Fig. 2. In the form of the invention illustrated in the 50 relation with the set 81 and another upsettable drawing, a laterally movable anvil 60 is slidably member at the extreme bottom of the chute 11, disposed on the base 6I and guided by overhang supported there by a stop 88 and by an extension 89 secured to the anvil 60 by screws 90. The an ing members 62 secured to sides of the base l. The anvil 60, as shown in Fig. 3, tapers upwardly vil extension 89 in the form of a cantilever bar to provide at the top a seat just wide enough to 55 provides a seat for the upsettable member against 2,413,270 3 the stop 88. In this position the upsettable mem ber is in the path of the clamping jaws '84. After the work has been disposed over the up settable member83 on the anvil 60 land the set 81 has upset the upsettable mem-ber 63, the afore said control is manually actuated to move the anvil 60 to the right. As the anvil 50 moves to'the right, the anvil extension 89 moves with it, 4 to it. The nose 18 thus acts to stop downward movement of all the upsettable members in the chute 11 except the one that was immediately next the stop 80. As the nose 18 moves to the left, the stop 8U also moves to the left and per mits the upsettable member which was next to it to slide down the chute 11 into position against . Ythe stop 88 and resting on the anvil extension 89 in position to be transferred to the top of the the upsettable member at the bottom of the chute 11, sliding on-its surface. The clamping 10 anvil 50 between the jaws S4 the next time the anvil 80 moves to the right. jaws 64 are provided with guiding edges 9| and As an example of a change that may be made, curved active portions 92, which engage the head the selector 19 disclosed in Figs. 1 and 2 may be of the upsettable member. Thus, as the anvil 60 reversed so that an upsettable member is selected is moved to the right, the upsettable member heldv by the stop 88 is guided by the edges 9| into po 15 from the chute 11 upon the movement of the anvil away from co-operating relation with the sition between the active portions 92 of the clamp set rather than upon the movement of the anvil ing jaws 64. When the anvil 6D has moved to its toward co-operating relation with the set, as is extreme right position and has received between disclosed. the jaws E4 an upsettable member from theA bot- Having thus described our invention, what we tom of the chute 11, it is automatically returned 20 desire to secure by Letters Patent and claim is: by mechanism, such as disclosed in the aforesaid A machine of the character described, com Hoyt patent, into co-operating relation with the prising a laterally movable anvil having rivet set 81, carrying with it the upsettable member be clamping means associated therewith, said rivet tween the jaws 64. When the anvil 68 is in its extreme right posi 25 clamping means being movable with said anvil, a set, an extension from said anvil for upsettable tion, the stop 89 has moved away from the leaf members, means to dispose an upsettable mem spring 83, which in turn, due to its initial set, ber on said anvil extension, means including said has moved the selector 19 to the right, moving anvil extension to support upsettable members the nose 18 away from the lowest upsettable mem ber in the chute 11 and permitting the upset 30 in the path of movement of said anvil and rivet clamping means, said rivet clamping means hav table members to drop down the chute 11 against ing means to guide an upsettable member dis the stop V8i), which has moved across the path posed as aforesaid into clamping relation with of movement of the upsettable members in the said clamping means as said anvil and rivet chute 11. When the stop 86 again engages the free end of the leaf spring 83 on the return move 35 clamping means move laterally away from said set, and means to move said anvil and upsettable ment of the anvil 60 into co-operating relation with the set 81, the selector 19 is moved toward the left, projecting the nose 18 between the rivet 'immediately against the stop 80 and the one next member into co-operating relation with said set.
