ALBERT G. GOWAN, OF CORSICANA, TEXAS.
BALING-PRESS.
SPECIFICATION forming part of Letters Patent No. 615,159, dated November 29, 1898.
Application filed June 30, 1897, Serial No. 642,937. (No model.)To all whom it imaq concern:
Be it known that I, ALBERT G. GOWAN, a
citizen of the United States, residing at Cor-
sicana, in the county of Navarro and State
5 of Texas, have invented a new and useful
Baling-Press, of which the following is a speci-
fication.
My invention relates to baling-presses, and
particularly to that class wherein the plun-
ro ger-beam is actuated by cam-pressure, the
cam receiving its motion from a sweep oper-
ated by horse-power or its equivalent; and
the object in view is to provide cooperating
main and auxiliary cam-faces adapted for
15 successive application of pressure to the
plunger-beam, whereby the maximum speed
of movement is communicated to the plun-
ger-beam during the first operation of the
stroke and whereby the speed is decreased
20 and the power proportionately increased as
the plunger approaches the limit of its move-
ment.
Further objects and advantages of this in-
vention will appear in the following descrip-
25 tion, and the novel features thereof will be
particularly pointed out in the appended
claims.
In the drawings, Figure 1 is a perspective
view of a baling-press constructed in accord-
30 ance with my invention. Fig. 2 is a plan
view of the operating mechanism, showing
in full lines the positions which the parts oc-
cupy during the first or preparatory portion
of a stroke and in dotted lines the positions
35 which the parts occupy during the succeed-
ing portion of the stroke when the speed of
movement is secondary to the power.
Similar numerals of reference indicate cor-
responding parts in both figures of the draw-
40 ings.
1 designates a base, upon one end of which
is arranged a baling-chamber 2, and 3 repre-
sents a plunger operating in the baling-cham-
ber and having a plunger-beam 4. The plun-
45 ger-beam operates between upper and lower
parallel guide-plates5 and G and also between
axially-vertical guide-rolls 7, and to the beam
is attached a rebounding springS, which, how-
ever, may be omitted when it is desired to de-
50 spend upon the elasticity of the material baledto return the plunger to its initial position.
The sweep 9 is attached to a cam-head 10,
fulcrumed at 11 upon the base and adapted
to bear at its face against a terminal contact-
point consistinm in the construction illus- 5
rated of an antifriction-roll 12, mounted on
the end of the plunger-beam. In connection
with this main cam, however, I also prefer-
ably employ an auxiliary cam 13, which is
arranged on the sweep 9 in advance of the 6o
initial portion of the curve of the main can
and is at a still more abrupt curve than the
same to cooperate with a bearing-point con-
sisting of an antifriction-roller 14, located on
the plunger-beam in advance of the bearing- 65
point 12 and in a different horizontal plane
therefrom. The object in arranging the bear-
ing-point 14 and the auxiliary cam 13 in a
different plane from the bearing-point 12 and
the cam 10 is to enable the auxiliary cam to 70
actuate the plunger-beam initially and then
transfer the operation to the main cam by
bringing the face of the main cam into con-
tact with the main bearing-point 12 before
the auxiliary cam releases the auxiliary bear- 75
ing-point 14. This produces a continuous
operation and avoids jar and at the same time
gives a rapid initial motion to the plunger
during that portion of the stroke when the
material being baled is loose. The rapidity 8o
of motion imparted by the main-cam face to
the plunger-beam gradually decreases from
the initial point toward the terminal point.
Various changes in the form, proportion,
and the minor details of construction may be 85
resorted to without departing from the spirit
or sacrificing any of the advantages of this
invention.
Having described my invention, what I
claim is- 90
1. In a baling-press, a plunger-operating
mechanism including a rebounding plunger-
beam, a main cam having a face for cooper-
ation with a main bearing-point on the plun-
ger-beam, and an auxiliary cam arranged in 95
advance of the initial point of the main cam
for cooperation with an auxiliary bearing-
point on the plunger-beam in a different plane
from the main bearing-point, the face of the
auxiliary cam receding from the fulcrum- Too
