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

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

block 82, while it is the lower portion of the se
lector 19 which is disposed in the channel 8|.

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

when the anvil 69 is moved to the left to move
the slot 85 and thus to move the selector 19 to the
left.

As shown in Figs. 1 and 2, there is an upset

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

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,

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
