WILLIAM R. COLMAN, OF QUINCY, ILLINOIS, ASSIGNOR OF ONE-HALF TO i FREDERICK C. ANDREWS, OF SAME PLACE.
BALING-PRESS'.
SPECIFICATION forming part of Letters Patent No. 678,941, dated July 23, 1901i Application filed November 28, 1900. Serial No. 37,972- (NO modem To all whom it may concern,.-
Be it known that I, WILLIAM R. COLMAN, a citizen of the United States, residing in Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication.
My invention relates to certain improvements in presses that may be used for baling hay, straw, cotton, excelsior, and the like; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a detail View illustrative of my invention and being part in plan and part in horizontal section. Fig. II is a detail side view. Fig. III is an enlarged perspective View of the brake mechanism and retractingspring. Fig. IV is a vertical section of the same. Fig. V is a horizontal section of the cross-head or lever-arm. Fig. VI is a top or plan view of the power mechanism, showing the parts in a different position from that shown in Fig. I.
Referring to the drawings, 1 represents part of the baling-chamber of 'a press, and 2 the plunger or traverser.
3 represents the pitman, the outer end of which carries a rigid head 4.
5 represents a sweep mounted on and rig-` idly secured to the upper end of a shaft 6, that passes through a hub 7 of a cross-head or lever-arm 8, that is rigidly secured to and turns with the shaft. The shaft is suitably journaled in a bed-plate 9, that is supported by a reach l0, that connects it to the balingchamber of the press. The outer ends of the cross-head 8 are provided with friction-rollers 11, (see Fig. V,) and in the operation of the press, as will hereinafter appear, these friction-rollers come against the outer end 12 of the head 4 of the pitman to force the plunger forward in the act of pressing the material.
13 designates a carrier-arm, upon which the pitman 3 rests and slides with frictional contact. As shown in Fig. III, the carrierarm projects horizontally from the lower washer 14 of a brake, 15 representing the upper washer of the brake. The washer 14 fits loosely on a round stud 16, projecting upwardly from the bed-plate 9, and the lower side of the washer 15 has a non-circular recess to receive a non-circular upper end 17 of the stud 16. The lower washer is thus free to turn on the stud, while the upper washer is held from rotation. The two washers are held to the bed-plate by a bolt 18, (see Fig. IV,) and between the washer 15 and a nut 19 on the bolt is a coil-spring 20. The adjacent faces of the washers 14 and 15 are provided with one or more inclines 21, as seen in Fig. III, so that when the carrier-arm is moved in the direction of the arrow the turning of the washer 14 against the washer 15 will cause the spring 2O to act as a brake to retard the movement of the washer 14, and this braking eifect acts to retard the rebound kmovement of the plunger by a projection 22 on the pitman coming against a projection 23 on the outer end of the carrier-arm before the plunger reaches the limit of its backward movement. To avoid a severe shock to the press on the rebound of the plunger, the bedplate is provided with a spring-bumper 24, a
.rubber bumper being shown against which a projection 24a.. on the carrier-arm contacts, as shown in Figs. II and III, the projection coming against the bumper as the carrier-arm reaches the extreme limit of its backward throw.
It is important to provide means to start the backward movement of the plunger in case there should be any tendency of the plunger to stick after the pressure is released, and to do this in a cheap and effective manner I secure a U-shaped spring 25 to the bed-plate 9, as shown in Figs. I and III. The free end of this spring is adapted to be engaged by a lug 26 on the washer 14 when the outer end of the carrier-arm is moved forward. To cause this forward movement of the carrier-arm, the head 12 of the pitman is provided with a projection 27, that comes against the back of the lug or ear 23 on the carrier arm shortly before the plunger reaches the limit of its forward movement, and when the carrier-arm is thus moved it compresses' the spring 25, so that when the IOO yIo
force is removed from the outer end of the-pitfriction of the pitman on the carrierarm,).
and as the carrier-arm is moved by the projection 22 coming against the projection 23 the inclines 21 on the adjacent faces of the disksl or washers 14 and 15 cause the washer 15y to be elevated against the pressure of the spring 20, and the spring thus acts as a brake to retard the rearward movement of the carrier-arm and the pitman that rests therein.
30 represents a spring connected by one end to the bolt 18 and at the other end to the pitman at a suitable pointand which acts to pull the plunger backwardly.
3l represents an arm connected to the washer 15 at one end and the other end of which is curved inwardly, as shown in the drawings. The curved end of the arm is connected by links 32 to the head 4 of the pitman, there preferably being a slot-and-pin connection between the links and the head 4, so that when the plunger is receiving the last part of its forward movement the pin will slide in the slot and avoid danger of break ing the parts. As the cross-head 8 is turned by the sweep the rollers 11 come against the armv 3l, andby moving the arm from the position shown in Fig. I to the position shown in Fig. VI acts to draw the pitman forwardly, thus effecting the iirst part of the advance movement of the plunger. This movement of the arm 31 also draws the outer end of the pitman inwardly, so that the next roller 11 will engage the outer curved end of the head 4 of the pitman, and the parts are so formed and disposed that one of the rollers 1l d oes not leave the curved end of the arm 31 until the other roller 1l is well seated against the end of the head 4. This is illustratedin Fig. VI, where one of the rollers 11 has still .to travel the distance of the inward curve on the arm 31, While the other roller 1l is moving from the advance corner of the head 4 to a central position against the head. The position assumed by the pitman and the arm 31 and links 32, when the plunger is forward and just before the cross-head leaves the outer end of the pitman, is indicated by dotted lines in Fig. I. To prevent the curved end of the arrn3l from contacting with the cross-head whena roller 11 rst comes against the arm, I form recesses 33 in the cross-head, as shown in Fig. V. e
In the operation of the press` one` of the; rollers 11: comes against the arm 31 anddraws the pitman 3 inwardly and forwardly'to bring the head of the pitman in front of the next roller 11. As this latter roller engages the head of the pitman it forces the same forward, giving the nal pressure to the plunger. Shortly before the pitman reaches the limit of its forward movement the projection 27 comes aga-inst theprojeciion 23 on the carrierarm and moves the latter forwardly, thus j storing up pressure in the spring 25, that acts to start the pitman and plunger in their rear- --ward movement when the roller 11 leaves the end of the pitman. In the rebound of the plunger and pitman the projection 22 engages the projection 23 on the carrier-arm and moves the arm back to its normal position, the spring 2O acting as a cushion to check the backward movement of the carrier-arm and the pitman.
