MARION D. GUTITRIE, OF HOUSTON, TEXAS
HAY-PREss.Specification of Letters Patent.
-Patented 3an. 26, 1909.
Application mied March 80, 1907. Serial No. 365,667.
To all whom it may concern:
Be it known that I, MARION D. GUTHRIE, a
citizen of the United States, residing at Hous-
ton, in the county of Harris and State of
STexas, have invented new and useful Im-
provements in Hay-Presses, of which the fol-
Iowing is a specification.
This invention relates to a hay or other
press of that type In which two compression
10 strokes are imparted to the plunger by one
continuous rotation of the sweep.
The invention has for one of its objects to
improve and simplify the construction and
operation of machines of this character so as
15 to be comparatively easy and inexpensive to
manufacture, composed of few parts and ef-
ficient and reliable in use.
A further object of the invention is the
provision of a hay press of comparatively
20 large capacity and adapted to operate with
little friction and with a light draft, which
includes a rotatable beam or element con-
nected with the sweep and provided wish
cams a4 its extremities for imparting motion
25 to the plunger through an oscillating frame
or triangle arranged in the path of the cams.
With these objects in view and others, as
will appear as the description proceeds, the
invention comprises the- various novel fea-
30 tures of construction and. arrangement of
parts which will be more fully described here-
inafter and set fox'th with.particularity in the
claims appended hereto.
In the accompanying drawing, which illus-
35 trates one of the embodiments of the inven-
tion, Figure 1 is a plan view of the hay press
with intermediate portions broken away.
Fig. 2 is a side elevation thereof. Fig. 3 is a
bottom plan view of the cam-carrying inem-
40 her or cross - piece. Fig. 4 is a side view
thereof.
Similar reference characters are employed
to designate corresponding parts throughout
the several views.
4s Referring to the drawing, A designates the
bed or base frame of the preis which~ is of any
approved construction and is provided at one I
end with a compressing chamber B of- any
approved form in which reciprocates a plun-
5o ger C. At the end of the frame or bed A op-
posite from the compressing chamber is piv-
oted a sweep D, the pivot 1 thereof passing
through the sweep and cross-beam 2 of the
hrame. Disposed between the sweep and
55 cross piece 2 is a horizontal member 3 rigidlysecured to the sweep by means of diagonal
braces 4 that hold the member rigidly at right
angles to the sweep. The member 3, which
is preferably a beam of wood, has its ends cut
away to form oppositely disposed cams 5 60
that are faced by metal fittings 6 that take
the wear. These cams areformed by under-
cutting the ends of the member 3; as shown
and they are adapted to alternately operate.
on the mechanism connected with the plun- 66
ger to impart two strokes to the latter by one
rotationl of the sweep. The usual lead pole 7
is employed that is bolted or otherwise se-
cured to the sweep and the braces 4.
The plunger C is hingedly connectedl with 70
a rod 8 which, in turn, is hingedly connected-
with a triangular frame or element 9. This
elemejit is mounted for oscillation on a ver-
tical pivot 10 mounted on the bed A adjacent
the 'rear end .thereof and constitutes a bell 75
crank lever. The element 9 is in the form of
a right angle triangle and the plunger rod 8 is
connected with one of its acute angles, while
the other acute angle or corner is disposed in
the path of the cams 5 so as to receive move- 80
ment by the cams wiping on the same, the
pivot 10 being located at the right angular
corner of the element 9. The elemsmit 9 is
adapted to be oscillated in one direction so as
to move the plunger on its compression 85
stroke and after the cain 5 disengages from
the. element, the latter, together with the
plunger, may be returned in any suitable
manner, as for instance, by an extension
spring 11. The portion of the element 9 oo
that is engaged by the cams is provided with
*a metal cap 12 so as to receive the wear.-
By undercutting the ends of the member
3, horizontal terminal flanges. - are formed
which are adapted to extend over the rear 95
extremity of the arm of the bell crank lever 9
and hold the latter down against the base
frame or bed -when the lever is tilted by the
cam so as to thereby prevent too great a
strain on the pivot 10. In other Words, the 100
element 9 is maintained in a horizontal plane
during its movement not only by the pivot
10 but by the terminal flanges on the mem-
her 3 engaging over the rear end of the said
element.15
In practice, the compressing chamber is
supplied with hay or other material to be
compressed and the sweep D is rotated in
any suitable manner, as for instance, by.
horse power, and one rotation of the sweep 11oNo. 910,667.
