FRANK S. CLARK AND JOSEPH A. BACHMAN, OF AUSTIN, TEXAS.
LOCKING DEVICE FOR BALING-PRESS DOORS.
SP-CIFICATICN forming part of Letters Patent No. 336,293, dated February 16, 1866.
Application filed December 18, 1885. Serial 1o. 18,104. (No model.)To al zwhont, it noay conce7; ,:
Be it known that we, FRANK S. CLARKniand
JOSEPH- A. BACHM AN, both of Austin, in the
county of Travis and State of Texas, have in-
5 vented a new and Improved Locking Device
for Baling-Press Doors, of which the follow-
ing is a full, clear, and exact description.
The object of our invention is to provide a
new and improved locking device for the doors
io of thebaling-chamber of a baling press, which
locking device is so constructed that all the
doors can be locked in a single operation and
by means of the same device, and may be
loosened simultaneously.
j5 The invention consists in the construction
and combination of parts and details, as will
be fully described and set forth hereinafter,
and then pointed out in the claims.
Reference is to be had to the accompanying
20 drawings, forming a part of this specification,
in which similar letters of reference indicate
corresponding parts in all the figures.
Figure 1 is an end view of a baling-box pro-
vided with our improved locking device, parts
25 being broken out and others being in section.
Fig. 2 is a front view of the same. Fig. 3 is a
detail view of the catch, parts being broken
out and others being in section.
The baling-chamber A is provided with the
30 two end doors, B, and the side doors, C, all
pivoted at their bottom edges to swing out-
ward-that is, from the baling-chamber. The
side doors, C, are provided with the battens E
at the swinging edges on the outer surfaces,
35 and the end doors, B, are provided with the
battens D. On the ends of the battens E the
catches Faresecured on the inner surfaces, so
that they can catch on the ends of the battens
D on the end doors, B. The platen-bars G
40 are held on the cross-pieces 1H, and two of said
bars G are provided with slots or with grooves
in their under sides for receiving the sliding
bars J, which project from both side edges of
the platen, and are held in their grooves or
45 slots by the clips K, secured to the under side
of the platen. To the ends of the bars J the
V-shaped locking-frames L are pivoted, and
on the battens E of the side doors the plates 3M
are secured, against which the said locking-
So bars can rest, and which serve to protect the
battens from mutilation. The apex of one ofthe locking-frames L is engaged with a hook,
N, on one door C and with the apex of the
other frame L the pulley-block O is connect-
ed, over which the rope P is passed, which 55
also passes over the pulley R on a batten on
the bottom of the said door.
The operation is as follows: The baling-
chamber is filled with cotton or other material
to be baled, and the doors are closed. By 6o
pulling on the ropeP the frames L are pressed
against the upper parts of the side doors,
whereby the doors are pressed firmly against
the sides of the chamber, and the catches F
on the battens of the said doors catch on the 65
ends of the battens of the end doors, B, and
thus hold the same locked. As the two lock-
ing-frames L are connected by the bars J, they
both have the same relative movement, and
operating one operates both. The follower 70
then compresses the material in the baling-
chamber, and when the desired degree of com-
pression has been reached the rope P is slack-
ened, thus permitting the material in the
chamber to force the upper ends of the side 75
doors, C, outward, whereby the catches F are
moved from the ends of the battens D on the
end doors, which are thus also released, and
when the rope P is loosened still more all the
doors can be swung down and the bale re- 80
moved. All the doors of the-baling-chamber
can thus be locked by means of the rope and
pulleys, and all the doors can be unlocked at
once.
Where the locking device is used on presses 85
having swinging tops, clamps are used to hold
the doors up when the box is being filled.
When full, the bagging is spread over the top
and the press-top is swung into place. Then
the locking-frames are swung down and fast- 90
ened and the light clamps removed.
Having thus fully described our invention,
we claim as new and desire to secure by Let-
ters Patent--
1. The combination, with a baling- chamber 95
having side doors, of sliding bars in the platen
and of locking-frames pivoted to said sliding
bars, substantially as herein shown and de-
scribed.
2. The combination, with a baling-chamber ioo
having two side doors, of sliding bars in the
platen, locking-frames pivoted to both ends of
