BALINGjPRESS.

SPECIFICTION forming part of Letters Patent No. 472,838, dated April 12, 1892.

Application tiled July 25 1891- Serial No. 400,743. (No model.)

drawings, forming part of this specification.

vMy invention relates to certain improvements in baling-presses; and it consists in features of novelty hereinafter fully de scribed, and pointed out in the claims.

Figure I is a top or plan view of my improved press. `Fig. II is a side elevation. Fig.

III is an enlarged top view of the power end of the press. Fig. IV is a similar View showing the parts in a different position. Fig. V is an elevation of the same parts. Fig. VI is a top view of the part of the press located centrally between the baling end and power end of the press. Fig. VII is an elevation of the same. taken on line VIII VIII, Fig. VII. Fig. IX is a vertical section taken on line IX IX, Fig. X. Fig. X is a detail elevation showing the Fig. xI

XI XI, Fig. II; and Fig. XII is a side elevation of the part shown in Fig. XI.

Referring to the drawings, 1 represents the baling-chamber of the press, connected to the power endof the press by means of a sill or bridge-tree 2.

3 represents the plunger, movedthrough means of a pitman consisting of an inner section 4 and an outer section 5, pivoted together at 6. The outer end of the outer section is pivoted .at 7 to the outer end of the link S, pivoted at its inner end at 9 to the outer end of the sill or bridge-tree 2. A link similar in its operation to the link 8 is shown in my patent, No. 446,311, of February 10, 1S91.

10 represents the central shaft, to which the power Inay be applied as in my patent referred to.

11 represents the cross-head, and 12 the outer arm, and 12a the inner arm, the crosshead and arms of this specification being the Fig. VIII is a vertical section same in their arrangement and use as in the 5o patent referred to, in which they are marked, respectively, 23, 25, and- 25, except in the.. present instance the arm l2 has a straight bearing portion leading to a curved bearing portion 12b near its inner end, which rolls around the end of the pitman as the plunger reaches the limit of its forward movement,

thus effecting a great power as the final pressure is being made.

13 representsa block pivoted to the outer 6o end of the arm 12a and having at its inner enda slot-and-pin connection 14 with the arm, this block having its counterpart in my patent mentioned, wherein it is indicated by the numeral 27. In that patent the free end of the block is forced to its inner position by means of a short spring 32, acting on the block between its pivot and the slot-and-pin connection of the block with the arm. To provide amore durable and effective spring arrangement, I now form an extension 15` on the inner end of the pivoted block, which projects beyond the slot-and-pin connection and to which one end of a spring 16 is connected, the other end of the spring being connected at 17 to the arm 12a. (See Figs. III and V.) With this arrangement the spring exerts a greater power on the block, as well as having greater elasticity and freedom of movement. In the patent referred to 4there was a loose contact between the outer end of the arm 25 (which corresponds to the arm 12 of this speci- Iication) and its point of contact between the end of the pitman andthe link, which at times was objectionable, as it is desirable to havethe arm always bear against the end of the pitman. To avoid this difficulty, I now form a lug or shoulder 18 on the link 8,which bears against the bac-k of the arm 12 or against the iiange 19, formed upon the under side of the arm. There is sufficient room between this lug or shoulder and the pitman 7 for the arm 12 to iit and work, asshown clearly in Fig. III, and it will be readily seen that this shoulder or lug 4will always keep the front face of the arm 12 in contact with the end of theV pitman, whatever` the position of the parts may be.

2O represents a friction-roller located on the under vside of the llink 8 and which travels upon a track 2l, secured to the sill or bridgetree 2. These features have their counterparts in my patent referred to.

'Secured to the sill vor bridge-tree about.v midway between the 'baling-chalnber"and the power end of the press is a bridge frame or casting 22, (see Figs. I, II, IX, and X,) towhich. bridge-frame is journaled a horizontal friction-roller 23, against which the side of ther section l4 of theipitman bears, `,the rolglergb'eing placed on the side of the 4pitlnan in which the latter hasv a tendency'to 'move as it is forced inv and outin the operation of the f press.
