LOCKING DEVICE FOR BALlNG-PRESS DOORS.

SPECIFICATION forming part of Letters Patent No. 336,293, dated February 16,1886.

Application tiled December 18, 1885. Serial No.186,104. (X0 model.)

To all whom it may concern.-

Be it known that we, FRANK S. CLARK and JOSEPH A. BAOIUIAN, both of Austin, in the county of Travis and State of Texas, have invented a new and Improved Locking Device for Baling-Press Doors, of which the following isa full, clear, and exact description.

The object of our invention is to provide a new and improved locking device for the doors of the balingchamber of a balingpress, 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.

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 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 abaling-box pr0- vided with our improved locking device, parts 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 two end doors, B, and the side doors, 0, all pivoted at their bottom edges to swing outward-that is, from the baling-chamber. The side doors, 0, are provided with the battens E at the swinging edges on the outer surfaces, and the end doors, B, are provided with the battens D. On the ends of the battens E the catches Fare secured 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 are held on the cross-pieces H, 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 slots by the clips K, secured to the under side of the platen. To the ends of the bars J the V-shaped locking-frai'nes L are pivoted, and on the battens E of the side doors the plates M are secured, against which the said lockingbars can rest, and which serve to protect the battens from mutilation. The apex of one of the locking-frames L is engaged with a hook, N, on one door 0 and with the apex of the other frame L the pulley-block O is connected, over which the rope P is passed, which also passes over the pulley R on a batten on the bottom of the said door.

The operation is as follows: The balingchamber is filled with cotton or other material to be baled, and the doors are closed. By pulling on the rope]? 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 ends of the battens of the end doors, B, and thus hold the same locked. As the two locking-frames L are connected by the bars J, they both have the same relative movement, and operating one operates both. The follower then compresses the material in the balingchamber, and when the desired degree of compression has been reached the rope l is slackened, thus permitting the material in the chamber to force the upper ends of the side doors, 0, outward, whereby the catches Fare 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 removed. 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.

WVhcro the locking device is used on presses having swinging tops, clamps are used to hold the doors up when the box is being filled. \Vhen full, the bagging is spread over the top and the press-top is swung into place. Then the locking-frames are swung down and fastened and the light clamps removed.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent-- 1. The combination, with a baling-chamber having side doors, ofsliding bars in the platen and of locking-frames pivoted to said sliding bars, substantially as herein shown and dc scribed.

2. The combination, with a baling-chamber having two side doors, of sliding bars in the platen, looking-frames pivoted to both ends of the said bars, and a rope and pulleys secured to one door and its locking-frame, substantially as herein shown and described.

3. The combination, with a baling-chamber having side and end doors, of sliding bars in the platen, locking-frames pivoted to the ends of the sliding bars, battens on the end doors, and catches on the ends of the battens on the side doors, substantially as herein shown and described.

4. The combination, with a baling-chamber provided with two side doors, of sliding bars in the platen, locking-frames pivoted to the ends of the sliding bars, the hook N on one door for holding the locking-frame of said 15 door, and a rope and pulleys connected with the other door and with its looking-frame, substantially .as herein shown and described.

5. The combination,with a baling-chamber, ofsliding bars above the same, and of locking- 20 frames pivoted to the ends of said sliding bars and serving to lock the doors, substantially as herein shown and described.
