SPECIFICATION arming part offntters Patent No. 724,063, dated March 31, 1903. y Application iilcdAugust 2dyl902.4 Serial No. 120,793. (No model.)

To all whom vit may concern:- r Be it known that we, LUTHER TRABUE, residing at Girard, in the county of Macoupin and State of Illinois, and CHARLES E. PUR- CELL, residing at Bellevue, in the county of Huron and State of Ohio,citizens ofthe United States, 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 Specification.

Our invention relates to a press for baling hay, straw, excelsior, and the like; and our invention consists in features of novelty hereinafter fully described, and pointed out in the' claims. l

Figure I iS a side view ofour improved press, part in section, part ofthe connection between the powerend of the press and the body or baling-chamber being broken away..

Fig. II is an enlarged longitudinal sectin taken on line II II, Fig. I. Fig. III is a per'- spective view of the cam-leven' Fig. IV is adetail vertical section of the body or balingchamber portion of the press` Fig. V is -a detail horizontal vsection ofthe same. Fig; VI vis a detail View showingrthe cam ofthev plunger-retracting mechanism. s

Referring to the drawings, 1 represents the body of the press, which may be of any desired construction. p

2 represents the plunger or traverser, and 3 4 represent the toggle formed in two parts, hinged together at 5, the inner end of the part 3 of the toggle being connected to the traverser at 6 and the part 4 of the toggle bei ing pivoted to the frame of the pressfby al shaft 7. On'the inner end of the part 4 of the toggle there is formed a cam 8, uponwhich bears a cable-9, that is attached tothe toggle at its joint by means of alink 10. Theother end of the cable 9 is connected toa turnbuckle 11, as shown in Fig. I, and the buckle is connected by Ineansof a link 12 to one end of a cam-lever 13, this lever being -pivotedat 14 to the outer end of a reach 15, that connects the power end of the press with the body portion of the press. The end of the lever 13 to which the link 12 is pivoted is provided with 1 et its joint ian inwardly-extending projection 16,1having an upper andalower rib 17, as seen in Fig. III. The other end of this lever is provided with a cam 1S, adapted to receivethe impact of friction-rollers 19, located onv the under side of the outer ends of a cross-head 20. The cross-head is pivoted to the reach 15 at 21, and to-it is secured the sweep 22.

In the operation ofthe press one of the rollers 19 comesagainstthe cam 18 of the lever as the sweep is turned and moves the lever from theposition shown in full lines, Fig. II, to the position shown in dotted lines, Fig. II. As it thus moves the lever the cable 9 is drawn around a fixed pulley 23, which moves the pitman from the position shown in full lines,'-Fig. IV, to the position shown in dotted lines, Fig. IV, thus causing the forward movement of the traverser. During the first part "ofthis movement the cable jbearsupon the cam 8 of the toggle and causes `theforward-"movement lof the traverser by the pressure of the cable against thecam,so `that`tlie tendency of the cable to pull against or in line with Athe pivot 7 of the Ontermein- -ber of'the'togg'le is overcome. As Ythe plunger advances the cam 8 leaves'the cable and the latter then hasv'a direct pullon the toggle During the ir'st part of the ad- Vance movement of' the `plunger the link 12 has a'directpull On the cable and during the latter part ofthe movement' the link is transformed into a leverV by coming against the ribs 17 -'so that the pull-point of connection between thecable and the cam-lever is at the commen'cementof the stroke at the point where the link is pivoted to the cam-lever, whereas at the final or last movement of the plunger the pulling-point between the cable and the cam-lever is at the outer end of the link 12, which is further removed. from .the pivot of the cam-lever.

As a means for retracting -thejt'raverser when onefof the rollers 19fleaves the outer Aend of the cam 18 we employ a ycam V.24', se-

cured by an arm 25 to the non-circular end of the pivot-shaft 7, that connects the outer section 4 of the toggle to the frame of the press. As the plunger advances the cam 24 is moved toward the power end of the press,

IDO

and as it does so it distends a coil-spring 27, that is connected at one end to the cam and at the other end to the frame of the press. When the cross-head leaves the cam 18 of the lever 18 the parts are free to be returned to their normal position, and this is effected by the contraction of the spring 27.

We claim as our invention- 1. In a baling-press, the combination of a baling-chamber, a traverser, a toggle pivoted at one end to the traverser, and-at the other end to the body ofthe press, a cam on the end of the toggle that is pivoted to the body of the press, a cable connected to the toggle at its joint, bearing against, but not connected with, the cam during the iirst part of the forward movement of the traverser, and means for exerting pressure on the cable to advance the traverser, substantially as set forth.

2. In a baling-press, the combination of a traverser, a toggle, a cable connected at one end to the toggle, a cam-lever, a sweep and cross-head for imparting movement to said cam-lever, a link secured to the other end of the cable and to the cam -lever, and ribs against which said link bears as the traverser advances so that during the first part of the movement of the cam-lever there is a direct pull on the cable and during the latter part of the movement the link is transformed into a lever by coming into contact with the ribs.

3. In a baling-press, the combination of a traverser, a toggle, a cable connected at one end to said toggle, a lever,a link connected to the other end of the cable and to the lever, a projection on said lever, ribs on the projec tion against which said link bears as the traverser advances, so that during the rst part of the movement of the cam-lever there is a direct pull on the cable and during the latter part of the movement the link is transformed into a lever by coming into contact withthe ribs, a sweep and cross-.head a cam on said lever, and friction-ro1lers carried by said cross-head, and adapted to engage the cam, substantially as set forth.

4.- In a baling-press, the combi-nation of a traverser, a toggle, a cam connected to the toggle, a cable connected to said toggle at its joint, bearing against, but not connected with, the cam during the first part of the movement of said traverser, a pulley around which said cable passes, a lever to which the other end of said cable is connected, a sweep and cross-head; a cam on the lever, and friction-rollers carried by said cross-head and adapted to engage the cam, substantially as set forth.

5. In a baling-press, the combination of a traverser, means forimparting forward movement to the traverser, and means for retract'- in g the traverser, consisting of a cam adapted to be moved by the means that advances the traverser, and a coil-spring connecting said cam to a fixed part of the press, substantially as set forth.

6. In a baling-press, the combination 0f a traverser, a jointed toggle, connected at one -end to the traverser and at the other end to the body of the press by means of a shaft, means for effecting the forward movement of the traverser, and means for retracting the traverser, consisting of a cam provided with an arm connected to said shaft, and a spring connected at one end to said cam and at the other end to a xed part of the press, substantially as set forth.
