Application filed September 7,1889. Serial No. 323,237. (No model.)

To all whom it may concern:

Be it known that I, Albert A. Gehrt, of Quincy, in the county of Adams and State of' Illinois, have invented a certain new and useful Improvement in Baling-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in presses for baling hay, cotton, excelsior, straw, and the like; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figures I and II are sections taken on line III, Fig. Ill, of the operating devices of my improved baling-press. Fig. III is a vertical section taken on line HI III, Fig. II, of the same. Fig. IV is a detail top view of the jointed spring and adjacent parts. Fig. Vis a detail section taken on line V V, Fig. I, showing the pivotal block. Fig. VI is a top view of the press. Fig. VII is an enlarged detail view taken on line VII VII, Fig. VIII, showing the collapsible portion of the wall. Fig. VIII is an enlarged vertical section taken on line VIIIVIII, Fig. VI, of the same.

Referring to the drawings, 1 represents the traverser of the press.

represents the inner section of the pitman, and 3 the outer section.

represents the sweep.

represents a cross-head loosely mounted on a vertical shaft 6, on which the operatingsweep 4 is also loosely mounted, a rigid connection being made between the sweep and the cross-head, or the sweep-casting and crosshead can be made in one piece. The crosshead is provided near each of its ends with a recess 7.

represents an arm loosely mounted on the shaft 6 and provided with a slot 9, receiving a pin 10, by which the outer end of the section 3 of the pitman is connected to the arm. The inner end of the section 3 of the pitman is pivoted at 11 to the outer end of the section 2 of the pitman.

represents a block fitting in a slot 13 in the arm 8 and pivoted to the arm, as shown at 14. On the upper end of this block is secured an anti-friction roller 15. The normal position of this block 12 is vertical, which position it may assume by gravity, and it will be seen that as the sweep and cross-head 5 turn on the shaft 6 the notched end 7 of the 55 cross-head will engage the anti-friction roller 15 on the upper end of the block 12. As the sweep continues to move around, the arm 8 and pitman 2 3 will be forced from the position shown in Fig. I to the position shown in 60 Fig. II, the traverser moving forward and the pin 10 moving from the outer end of the slot 9 to the inner end, thus decreasing the speed and increasing the power. As the parts reach the position shown in Fig. II, the lower end of 65 the block 12 comes against a cam 17, secured to the frame of the press, which causes it to tilt or turn on its pivot 14, which disengages its upper end or the friction-roller 15 from the end 7 of the cross-head 5, thus dis- 70 connecting the cross-head 5 from the arm 8, and the latter, with the traverser and the pitman 2 3, recedes to the position shown in Fig.

I. The sweep and cross-head 5 continuing around, the other end of the cross-head 5 comes 7 5 against the block 12 again and the operation just described is repeated.

I thus produce a continuous press with a very cheap and effective construction which is not liable to get out of order. The arm 8, 80 with the pitman 2 3, is caused to recede (after the cross-head 5 leaves the block 12) under the expansion of the compressed material, and this may be accelerated or assisted by means of a jointed spring 20, secured at one 85 end to the frame of the press and at the other end to the joint of the pitman 2 3.

To prevent a sudden stop to the backward movement of the traverser, I make one or more walls of the baling-chamber collapsible 90 or capable of being pressed inward into the path of the traverser, which comes against this wall of the press or baling-chamber and its movement is resisted by frictional pressure. This device is shown in Figs. VII and VIII. 95 21 is the wall of the baling-chamber, which preferably consists of a thin sheet of metal.

represents cams secured to the frame of the press by pivots 23 and provided with levers 24, connected by a link 25, the upper end 100 of which is threaded at 26 to receive a screw 27, passing through a threaded box 28, se2

438,540 cured to the frame of the press and provided with a handle 29, by which it is turned. It will thus be seen that by turning the handle 29 the xvall 21 of the baling-chamber may be 5 forced inward, as shown in Fig. VIII, by the cams 22, for the purpose stated.
