SPEGIFIGATION forming part of Letters Patent No. 494,915, dated April 4:, 1893.

Application filed June 26,1891.

To all whom it 11mg concern.-

Be it known that we, J OHN 1V. BROWN and ALBERT A. Gnnnr, both of Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Improvement in Bailing-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This improvement relates to improved means for working the feeder by a connection with the pitman. Also to the described means for the insertion of the partition block.

The novel features of the invention are set forth in the claims.

Figure I is a side elevation of the feeder and part of the body of the press. Fig. II is a side elevation of a part of the press showing the mechanism for insertion of the partition blocks. Fig. III is a perspective view of the sliding door to the entrance opening for the partition-block. Fig. IV is a perspective view of the dog which is located upon the cog sector for engagement with the rack. Fig. V is a perspective view of the slide to throw the dog out of the path of the rack. Figs. VI and VII are horizontal sections, taken at VI-VII, Fig. II, showing the plunger and other parts in different positions. Fig. VIII is a detailed view of the stop 40 on the quadrant 28.

l and 2 are the lower and upper main sills.

3 is the bottom, a the top and 5 the sides of the press-box.

6 are the upright girts connecting the upper and lower sills.

7 is the crank wheel driven by any suitable means. The wheel 7 has bearing in a metal frame or plate 8 firmly bolted to the sills.

9 is awrist-pin or crank pin passing through the wheel 7. To the pin 9 is connected one end of the straight pitmau 10, the other end being connected by a hinge joint 10 to the plunger 11. The pitmau is a rigid bar which reciprocates and oscillates between the main sills. Upon the sides of the pitman are campins 12 armed with anti-friction rollers 12.

13 is a lever pivoted to the main frame at 14. The lever is preferably forked so as to embrace the pitman and has cam or doubly curved slots 15 to receive the roller-armed Serial No. 397,627. (No model.)

pins 12 so that as the pitman moves forward and backward the lever 13 is made to oscillate on the pivot 14..

16 is a feeder firmlyfixed to the upper end of the lever 13, and provided with a head 18, strengthened by a brace 19.

17 is a brace extending from lever 13 to the feeder 16. The head 18 descends into the feed opening of the press box as the plunger recedes to its rear position, forcing the bunch of hay or other material down into the box. The plunger is shown in its rear position by full lines in Fig. VII, and broken lines in Fig. I. The frame composed of the lever 13, and feeder 16, 18, is shown in its upper position by f ulllines in Fig. I and in its lower position by broken lines in the same figure. The descent of the head 18 takes place when the pin 9 is in the lower half of its revolution, so that it moves at a slower speed and greater force when descending than when ascending, as the pins 12 are at a greater distance from the fnl crum or pivot 14 when the head is on its descent, and the purchase, consequently, greater than on the upward movement of the head 18, when the pins 12 are nearer the folcrum 14.

20 is a longitudinal bar fixed to the plunger and having upon it a rack 21 and at the bottom of the rack ahorizontal flange 22 that extends flush with or somewhat in advance of the ends of the teeth, at the front end. This flange at the rear end extends only to the rear side of the rear tooth 21.

25 is a cam wheel fixed to a vertical shaft 26 having bearings at 27 in the main sills. The wheel25 has a spur quadrant 28 adapted to engage the rack at 21 at certain times. Upon the cam-wheel is a dog 29 pivoted at 30 to the side of the wheel 25 and having a projection 31 adapted to engage the first tooth 21 of the rack when the projection is thrown out by the outward turning of the dog on its pivot.

32 is a spring adapted to throw the dog in position to engage the tooth 21.

33 is a stud upon the dog armed with an anti-friction roller 38 that bears against an incline 34, when the incline is in its normal position, as seen in Figs. 11 and VI. The incline is guided in its endwise movement by its extension suitably supported in an opening in one of the girts 6 and by connection at 36 to the lower end of a hand-lever 37. The lever 37 is fulcrnmed at 38 to the body of the press. The projection 31 of the dog has a down-turned tooth 39, whose purpose is to prevent the engagement of the projection 31 with any tooth of the rack 21, except the first tooth 21, for it will be seen that the pro jection 39 would slip along the flange 22 and the projection 31 could not come into engagement with the teeth of the rack, even when the incline 34 is in its forward position. When, however, the incline 34 is in its forward position, as seen in Fig. VII, and the forward movement of the plunger has carried the tooth 21 past the end of the projection 31, the projection swings into position behind the tooth 21 and on the return or backward movement of the plunger the tooth 21 comes in contact with the projection 31 and turns the cam wheel so that the quadrant 28 is engaged by the rack 21, and the cam wheel 25 is swung about one-fourth of a turn from the position seen in Fig. VI to that seen in Fig. VII. I/Vhen the dog 29 is'engaged by the tooth 21 it bearsagainst the stop 40 upon the quadrant 28. This movement of the camwheel takes place as the plunger is moving backward after the incline 34 has been thrown forward by the movement of the lever 37. The movement of the cam-wheel only takes place on the insertion of a partitionblock, at other times the plunger moves backward and forward in packing and pressing the hay or other material Without moving the cam-wheel as the dog is kept out of engagement with the tooth 21 by the incline 34 acting on the stud 33. The press box has in the side an opening 41 for the entrance of a partition-block 42.

43 is an open topped guide-way for the partition-block secured to theside of the pressbox. The partition-block is placed in the guide-way and is forced into the press-box by means that will now be described. 44 is a lever swinging on a pivot or hinge 45 and having a stud 46 armed with an anti-friction roller 46 that enters a cam slot 47 of the cam-wheel.

The construction is such that the described movement of the cam-wheel from the position seen in Fig. VI to that seen in Fig. VII will move the free end of the lever 44 toward the body of the press. To the free end of the lever 44 is hinged an arm 48, whose end 49 plays in the guide-way 43, the shank of the arm working in a horizontal slot 50 in the side of the guideway. The movement of the lever 44 is such as to carry the partition-block into the press. In order to prevent the block falling toward the plunger an arm 51 bears against the side of the partition block, said arm being hinged to the lever 44 near its free end and engaged and held by the beveled cross bar 51 when thrust into its extreme inner or holding position. The two extreme positions of the arm 51 are seen in Figs. VI and VII, the arm being withdrawn before the hay, as the plunger moves forward.

52 is a sliding door that closes the opening 41 except when a partition block is entering. This door has a stud 53 pivoted in the lever 37, at 54 so that when the upper end of the lever is moved backward, the door 52 is opened.

55 isa dog in the form of a bell-crank, its lower arm engaging the cam-wheel and preventing its movement until the dog is lifted. The upper arm of the dog is connected by a rod 56 with the lever 37. It will be seen from the foregoing that the sliding door is closed in its normal position, and that the lever 37 is normally in the position shown in Fig. II. When the lever 37 is moved backward into the position seen in Fig. II, shown in dotted lines, the sliding door is opened, the dog 55 lifted, and the incline 34- moved forward, allowing the spring 32 to throw the tooth 39 of the dog 29 against the rack 20. As the movement of the plunger brings the gap 23 to the tooth 39 the tooth enters the recess and the tooth 21 engages the dog and moves the camwheel until the other teeth of the rack 21 engage the quadrant 28, and the cam-wheel is swung around forcing the partition-block, (which had been previously dropped into the guide way 43) into the press. The lever 37 can be then moved forward and the dog 29 is retracted as soon as the backward movement of the oam-wheel brings the stud 33 against the incline 34. In case the door has not been closed before the plunger makes its forward movement, it is closed automatically by the pressure of a projection 60 upon the rack bar 20, said projection coming in contact with the projection 62 upon the sliding door 52. It will be seen that the projection is above the level of the rack 21 and quadrant 28.

61 is a lug or projection on the upper side of the cam wheel, and extending beyond the periphery of said wheel, its position being such as the rackbar is moving forward the projection 60 comes in contact with it, and carries the cam wheel into its normal position, in case it may be slightly out of such position from any cause.
