BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 485,072, dated October 25, 1892.

Application filed April 22, 1892. Serial No. 430,258- (No model.)

To aZZ whom it may concern: 1

Be it known that 1, CHARLES E. WHITMAN, of the city of St. Louis, in the State of Missouri, 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 partof this specification.

My invention relates to certain improve ments in presses of the continuous type for baling hay, straw, 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 top view of the power end of my improved press. Fig. II is a side elevation of same. Fig. III is a section taken on line III III, Fig. IV. Fig. IV is a section taken on line IV IV, Fig. III. Fig. V represents a modification of the construction shown in Figs. III and IV. Fig. VI is an enlarged top view of the power-head. Fig. VII is a top view of the central portion of the press, and Fig. VIII is an elevation of same.

Referring to the drawings, 1 represents a beam connecting the baling-chamber 2 to the power portion of the press.

3 is the sweep, and at the power-head, mounted on a shaft or heavy rod 5. The sweep and head are connected in any suitable manner,

so as to turn together on the shaft or rod 5.

6 is the pitman, secured to the plunger 7, as usual, and its outer end is formed with an inner shoulder 8 and an outer shoulder 9.

The power-head 4 is peculiar in its construction. (See Fig. VI.) It has two outer bearing-points 10, preferably armed with rollers 11, and two inner bearing-points 12, preferably armed with rollers 13. In the operation of the press as the power-head is moved by the sweep one of the points 10 comes against the shoulder 8 of the pitman, forcing the pitman and plunger forward with a rapid movement. Just before the point 10 leaves the shoulder 8 one of the points 12 comes against the shoulder 9 of the pitman and completes the movement of the plunger with a slow and powerful pressure, and just before the pitman is brought into line with the center of motion of the power-head its extreme end 15 comes in contact with the power-head at about the point marked a, which causes the pitman to be disengaged from the powerhead, permitting the plunger to recede under the back expansion of the compressed material, which may be assisted by a spring 17, the pitman returning on the same side of the press, and in its backward movement all danger of its striking the points 10 is prevented by projections or corners 18 on the powerhead, which will ward the pitman 06 from the bearing-points 10. The further movement in the same direction of the sweep and cross-head will bring the next points 10 and 12 into engagement with their shoulders 8 and 9 on the pitman, and the action described is repeated, one revolution of thesweep effecting two forward movements of the plunger.

The device is an exceedingly strong, cheap, and durable one, as well as very effective, as has been found by practical tests.

Should the plunger and pitman fail to return to the limit of their backward movement there might be danger of the bearing-points 1O engaging the shoulder 9 of the pitman, and to avoid any danger of this kind I put a cam 19 on the end of the pitman, (this cam is out of the path of the bearing-points 12,) against which the parts I) of the power-head will strike, and by forcing the pitman laterally will prevent the bearing-points 10 from engaging the shoulder 9. To permit this lateral movement, of the pitman at such times, I employ a device Which in its preferred form consists of an arm 21, pivoted to the pitman at 22 and connected at its other end (see Figs. I, III, and IV) to a block 23, mounted on a rod 24:, one end of which is secured by a bracket 25 to the beam 1. The other end of the rod fits in aslot 26 of a casting 27, secured to the beam 1, the casting having a socket 28, in which fits a spring 29, that tends to hold the rod 24: away from the pitman G. The block 23 is held against the casting 27 (or against a washer 30, which bears against the casting 27) by means of a spiral spring 31, surrounding the rod 24, this spring permitting a slight movement of the block on the rod when necessary. It will thus be seen that should the part Z2 come against the cam 29 the outer end of the pitman will be forced laterally and will then be drawn back to its normal position by the spring 29, acting through the rod 24, block 23, and arm 21.

In Fig. V, I have shown a modification of the spring 29, which consists in forming the arm 21 in two parts, oneof the parts having a socket 32 to receive the end of the other part and a spring 33, the part ofthe arm fitting in the socket having a head 34, between which and a nut 35 on the socket part of the arm the spring 33 bears. In this construction the spring 38 will yield to the lateral movement of the pitman and will draw the pitman back to its normal position.

The plunger 7 of the press is provided with a stop extension 40, to which a leaf 41 is hinged at 42. The extension 40 is pivoted to the plunger, as shown at 43, so that it will move freely'in the frame of the press and so that any twisting of the plunger will not be transmitted to the extension or to the leaf 41, The leaf 41 has cam-shaped sides 44, which as-the plunger is forced into the press come against cleats 45, secured to the inner wall of the baling-chamber, as shown in Fig. VIII and by dotted lines in Fig. VII. It will thus be seen that as the plunger is forced inwardly the leaf 41 will be raised up into a horizontal position and will close the mouth of the hopper 46 while the plunger is in its forward po-v sition, thus avoiding the possibility of mate-. rial entering the baling-chamber behind the plunger.' Then as the plunger recedes the leaf 41 will drop down into the position shown in Fig. VIII, thus shortening up the press and. permitting the draft-animals to step over the beam and pitman close up to the baling-cham- I ber of the press.

47 represents a roller, upon which the Outer end of the pitman rides and is supported from vertical movement.

I claim as my invention- 1. In a full-circle baling-press, the combi: nation of a baling-chamber, a plunger, a pitman having a cam and a plurality of shoulders on its outer end, a sweep, and a powerhead having means to engage said earn and having a plurality of bearing-points on each side of its center, which are arranged to. suecessively engage the shoulders of the pitman, said cam being out of the line of movement of said bearing-points, substantially as and for the purpose set forth.

2. In a full-circle baling-press, the combi nation of a paling-chamber, a plunger, a pitman having an inner and an outer shoulder and a point 15, a sweep, and a power-head,

man having an inner andan outer shoulder,

a cam secured to the pitman at the outer shoulder, a sweep, and a power-head, said power-head having an inner and outer bearing-point on each side of its center and having a part b for engaging said cam of the pitman, substantially as and for the purpose set forth.

4. In a full-circle baling-press, the combination of the baling-chamber, a plunger, a pitman having an inner and outer shoulder, and a camon the pitman secured thereto at the outer shoulder, a' spring-actuated arm connecting the pitman to the frame of the press, a sweep, and a power-head, said pewerrhead having an inner and outer bearing-point on each side of its center and having a part b for engaging said cam, substantially as and for the purpose set forth. I

5 In a fullrcircle baling-press, the combination of a balingwchamber, a plunger, a pitman having an inner and outer shoulder, and a cam located at the outer shoulder, an arm pivoted to the pitman, a spring-actuated rod to which the arm is connected, a sweep, and a power-head having inner and outer hearing points on each side of its center, and a part b for engaging said cam, substantially as and for the purpose set forth.

6, In a full-circle balingrpress, the combination of a baling-chamber, a plunger, a pitman having an inner and an outer shoulder, an arin'pivoted to the pitman at one end, a rod upon which the other end of said arm is mounted, a spring 31, located on said rod, a sweep, and a power-head having inner and outer bearing-points for engaging the, shoulders on the pitman, substantially as and for the purpose set forth.

Z. In a haling-press, the combination of a baling-chamber, a plunger, means for moving the plunger, an extension pivoted to the plunger, a leaf hinged to the extension and provided with cannshaped sides, and cleats against which the cams of the leaf impinge, substantially as and for the purpose set forth.
