When the parts are assembled as described
and as shown in Fig. 1 of the drawing a
draft animal is hitched to the sweep 4 in the
usual manner and the arbor 3 is rotated. As
5 the master wheel 5 rotates upon the axis of
the arbor the teeth 6 are carried around and
when the said teeth engage a beveled pinion
11 at one side of the frame 1 a space 7 is
moved over the bevel pinion at the other side
10 of the said frame. Thus as the pinion 11 is
engaged by the teeth to rotate one of the
stub shafts 9 and gear wheel 10 to cause one
of the plunger rods to make an active stroke
the stub shaft 9 at the other side of the frame
15 is free and may be rotated in a directions
opposite to that in which it rotates when
causing its attached plunger rod to make an
active stroke and presuming that the last
said plunger rod has just completed an
20 active stroke the tension of the spring 15
attached thereto will cause the plunger rod
to retract. Thus it will be seen that by rea-
son of the fact that the stub shafts 9 are in
alinement with each other and the teeth 6
25 and spaces 7 are alternately arranged uponI
the master wheel 5 and the teeth are dia-
metrically opposite the spaces and vice versa
throughout the entire series that but ne
plunger rod at a time is making an active
30 stroke, and during such active stroke the
other plunger rod is retracting. During the
longitudinal movement of the plunger rods
17 the racks 19 carried thereby are held in
engagement with the gear wheels 10 by the
35 rollers 18 and during the operation of the
press sweep the edges of the master wheel 5
are braced in a downward direction toward
the beveled pinions 11 by the rollers 8 which
are journaled in the frame 1.
40 Having described my invention what I
claim as new and desire to secure by Let-
ters Patent is:
1. A power mechanism for presses con-prising an approximately rectangular frame,
uprights mounted upon the frame and 45
spaced from the ends thereof, stub shafts
journaled for rotation in the frame and said
uprights, gear wheels fixed to the stub shafts
and located between the ends of the frame
and the uprights, beveled pinions fixed to the 50
inner ends of the stub shafts, an arbor jour-
naled for rotation in the frame, a sweep at-
tached thereto, and a master wheel carried
by the arbor and having means adapted to
engage the beveled pinion. 55
2. A power mechanism for presses com-
prising an approximately rectangular frame,
uprights mounted upon the frame and
spaced from the ends thereof, means for at-
taching press plunger rods guide troughs to 60
the ends of the frame and said uprights,
stub shafts journaled for rotation in the ends
of the frame and in said uprights, gear
wheels carried by the stub shafts and located
between the ends of the frame and the up- 65
rights, beveled pinions fixed to the inner ends
of the stub shafts, an arbor journaled for
1 rotation at the middle of the frame, a sweep
attached to the arbor, a master wheel fixed
to the arbor and located between the upper 70
and lower sides of the frame, said master
wheel having upon its under side several sets
of gear teeth separated by spaces and adapt-
ed to engage the beveled pinions upon the
stub shafts, and rollers journaled in the 75
frame and bearing upon the upper side of
the master wheel in the vicinity of its pe-
riphery and above the beveled pinion.
In testimony that I claim the foregoing as
my own, I have hereto affixed my signature 80
in the presence of two witnesses.
