causes the element 9 to be oscillated to re-
ciprocate the plunger twice, thus enabling
a double charge of hay to be compressed.
The construction of the press is simple, dura-
5 ble and comparativelyy inexpensive and the
parts are so proportioned as to obtain an in-
creased leverage, so that a powerful com-
pression of the materials is obtainable.
I have described the principle of opera-
tion of the invention, together with the ap-
paratus which I now consider to be the best
embodiment thereof, but I desire to have it
understood that the apparatus shown is
merely illustrative and that such changes'
may be made when desired as are within the
scope of the claim.
Having.thus described the invention, what
I claim is:-
In a press, the combination of a support-
ing frame, a compressing chamber at the for-
ward end thereof, a plunger movable in the
chamber, a rod pivotally connected with the
plunger, a sweep pivoted* on the frame, a
.member rigidly connected with the sweep and
formed at its ends into cams, and horizontal 2
terminal flanges projecting beyond the cams,
an oscillatory element pivotally mounted on
the frame between the chamber and sweep
and having a portion arranged in the path of
the cams and over which the said. flanges 30
move, a hinge connecting the plunger rod.'
with the element, and means connected with
the element for returning the sane and the
parts attached thereto to normal position.
In testimony whereof, I affix my signa- 35
ture in presence of two witnesses.
