SPEGIFICATION forming part of Letters Patent No. 651,442, dated as 12, 1906. Application filed March 20, 1899. Serial No. 709,729. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE D. LEEDLE, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Wringers, of which the following is a specification.

My invention relates to improvements in wringers, and it especially relates to that class of wringers which are formed with metal frames.

The object of my invention is to construct a wringer in which the operating parts are readily adjustable to the different work to be performed, while the construction of the wringer is such that it may be readily assembled with a minimum of machine-work and when constructed and assembled shall be strong and durable. I attain this object by theconstruction shown in the accompanying drawings, in which Figure 1 is a front elevation of a device em- Figs. 2 and 3 are detail views of some of the various parts shown in perspective Fig. dis a detail view,

partly broken away, showing portions of the upper arch or brace-rods and the housing for the springs. Fig. 5 is a detail view in perspective of one of the side frames, showing the position of the upper-roll bearings. Figs. 6, 7, and 8 are detail views in perspective of the spring-levers, the connecting-links, and the bearings supported thereby, respectively. Fig. 9 is a sectional view of a portion of the frame, showing the connections for the lower brace rod or bar. Fig. 10 is a detail view of one of the rolls and its bearings, partly in section. Figs. 11 and 12 are detail views of the brace 71. with its hook h. Fig. 13 is a detail View of the opening 71, in one of the side pieces.

Like parts are represented by similar let: ters of reference in the several views.

The frame of my improved wringer is formed of side pieces a a, which are connected together at the top with the arch or upper brace-rods b and at the bottom by a lower brace rod or apron h, which extends across the frame adjacent to the lower roll and serves as a guide for the materials operated on thereby in the usual way. The upper and lower rolls are each supported in loose bearings 6, Wl ll(3h have trunnions c with V-shaped edges on which they are supported, the bearings for the upper roll resting in contact with the lugs of the side frame and the bearings for the lower roll being supported in links f, which are connected at the top to levers d, which extend into a housing 0, forming part of the upper arch, and in which are springs c, which contact with the inner ends of the said levers d. Said links have slotted openings, as shown in Fig. 7, and have the upper ends bent inwardly for the purpose of engaging the levers.

The upper brace-rods b b are formed with studs 12 b at their outer ends, extending from each side of said brace-rods. There is further formed integral with each of said rods a projection 12 extending downwardly, with a hole 6 in its lower end. The sides of the frame a a are formed with notches a the top of each of said sides a a are formed shoulders at", which shoulders are adapted to bear against the projections b b. A bolt 5 passing through the hole 5 rests in the bearing surfaces or notches a of the side pieces a a. The levers d d are formed with studs cl d, projecting upwardly at one end and from each side of said lever. The opposite end of said lever is formed to extend into the housing a, as shown in Fig. 1, and. by means of the prongs c in Fig. 2 connects with the spring 0. Said levers d d are further formed with an opening (1 to fit over the projection 12 and with bearing-surfaces (i which bear against the bolt d which forms a fulcrum for each of the said levers and a connection to retain them in position. The links f are formed with openings f at each end and central openings f for the bearings for the upper roller. Said links are supported by the lovers d d by reason of the upper openings of each link fitting over the studs cl d, and thus the levers yieldingly support the bearings for the rollers, as hereinafter more fully described. The lower openings of said links receive the bearings for the lower roller.

Each side piece a is formed near the bottom on one side with a hook-shaped flange a with an opening a and a wedge-shaped projection a Said side piece is further formed with an offset portion a The lower brace-rod or. apron h is formed with arms h,

.in 71,4 in the side iece.

extending rearwardly, with hooks h extending downwardly and adapted to fit an open- The said bracerod h is further formed with an opening at each end, through which passes the bolt a which also passes through the flanges a and offset portion a and thus said apron assists in holding the end pieces of said frame firmly together. The projecting lugs a and a as shown in Figs. 3 and 5, are slotted in opposite directions, so that the bolt (0 can be slipped through said openings and will bear against the web-shaped projection a near its center, so that said bolt will be held rigidly in position. The clamping ends h of said wringer swing about said bolt a". The bearings e are formed cylindrical or of a barrel shape, with the V-shaped lugs 6' extending from the sides of the same and an oil-opening e in the top thereof. The V-shaped lugs of the upper cylindrical bearing are adapted to extend through the central openings of said links and to fit'against the shoulders a", formed in the sides a a, the sharp edges of said lugs contacting with the shoulders. The lower cylindrical bearing e fits into the lower openings of the links ff, the sharp edges of the lugs e contacting and bearing against the lower ends of said links. The bearings e e by reason of their construction incase the shafts or journals of the rollers and by the constructions shown are adapted to reduce the friction and will permit an alinement to every position to which the rollers may be forced. The shafts g are formed of tubes 9 into which the journal-rods g are fitted and riveted at g with shoulders at 9 thus dispensing with washers, and thus forming a cheap and very durable shafting.

It will be seen from the above description that I form a wringer the parts of which may be readily assembled with but little machinework. The construction of the side frames and the arch in connection with the lower brace-bar orapron is such that the parts when hooked together and brought into their normal positions and the lower end secured by the bolts a will be held without other means of fastening. The arrangement of the slotted openings for this bolt in connection with the wedge-shaped lug of permits the casting of these parts without the aid of cores and avoids the necessity of drilling or otherwise providing the holes for such bolts.

It will be noticed that the side frames are open at the bottom, this opening being closed and the parts held together firmly by the arms h on the lower brace-rod or apron. This arrangement permits the ready assembling of the rolls in the frame before the parts of the frame are finally locked together, the parts being securely locked by hooking the lower ends of the side frames together in the manner described. It will also be noted that the trunnions on the journal-bearings are so constructed that the V-shaped or knife edge on which the trunnion bears is in a line with the center of the bearing-that is, if extended this line would cross the axis of the journal at right angles, so that the journal is substantially pivoted on a line with its center.

Having thus described my invention, I claim- 1. In a frame for wringers, the combination of an upper brace-rod, independent bifurcated side pieces supporting each end of said rod, a lower brace-bar fastened at each end to one side of said side pieces and formed at each end with a hook-shaped arm adapted to fit into an opening in the opposite side of each side piece, and means for locking said side pieces at their upper ends to said upper brace-rod.

2. In a frame for a wringer, the combination of an upper brace-rod, independent side pieces supporting said rod, and levers pivotally held by said upper brace-rod for supporting the bearings for said wringer, a lower brace-rod fastened at each end to one side of the side pieces and formed with hookshaped arms at each end adapted to fit into openings in the opposite sides of the side pieces, and means for forming locking-joints at the top'and bottom of said frame.

3. In a frame of a wringer, the combination of an upper brace-rod with studs projecting at each end therefrom, and supportingarms formed integral therewith and extending downwardly, independent side pieces formed with shoulders at the tops thereof adapted to bear against said studs with bearing-surfaces at the sides, levers supported by said arms, and means for locking said side pieces against said levers and supportingarms for the purpose of forming a lock-joint at the upper ends of said side pieces.

4:. In the frame of a wringer, the combination of an upper brace-rod with studs at each end and supporting-arms extending down wardly at each end thereof, levers with bearing-surfaces pivotally held by said supporting-arms, independent'side pieces adapted to be locked rigidly together against said levers by locking-joints, a lower brace-rod connectin g said side pieces,and meansfor locking said lower brace-rod to the opposite side pieces.-

5. In a wringer, a rigid frame, supporting levers with upwardly-projecting studs at one end of same adapted to support independent links, independent swiveled bearings supported in said links to incase the roller-journals and adapted to adjust themselves to the positions assumed by said rollers.

6. In a wringer, a rigid frame formed with lock-joints, levers with upwardly-projecting studs at one end of same, independent links with slotted openings the upper ends of same being bent inwardly and adapted to'be'supported on said levers, independent barrelshaped swiveled bearings supported in openings in said links incasing the roller-journals and adapted to adjust themselves to the varying positions assumed by said rollers.

7. A wringer consisting of upper and lower each of which is provided with projecting trunnions having V-shaped or knife edges for supporting the same, said V-shaped or knife edges being formed in line with the axis of said journal, substantially as specified.

In testimony whereof I have hereunto set my hand this 17th day of February, A. D.
