Referring now more particularly to the char

cially designed» for use in power forging presses.
A further object of this invention is to pro

secured to the bed 2 of the forging press by means

ment from said upstanding position to a position
of bolts 3. An upstanding die holder 4 is nor
mally seated on the base I adjacent one end
opening laterally, whereby to permit the ready
thereof; said die holder surrounding and sup
porting an upstanding cavity die 5 which includes
insertion of the work in the die, or the removal
of the forging therefrom, particularly when the

the forging P has been formed by the press in
the upstanding die 5, the hand lever 20 of bell
means are found desirable, the same may be in~
corporated in this embodiment of the invention
and can be of the manually actuated type shown
in Figs. 1 and 2, or the power actuated type,
shown in Fig. 3.
From the foregoing description it will be read
the operator strikes the head E5 of rod l2 with a
sledge hammer, which causes said rod to project
substantially ful?lls the objects of the invention
at the other end through die port Mr and force,
as set forth‘ herein.
crank H is swung upward, which causes the die
holder to tip over to the laterally opening posi

driving the latter out of the die. The spring I6
serves as a shock absorber tor the blow imparted ;
to head 15.
After the forging has thus been removed from»
the die the hand lever .28 is returned to normal 15
horizontal position, which causes the die holder
and die to likewise be returned to upstanding
position for the next forging operation.
