SPECIFICATION forming part of Letters Patent No. 725,727, dated April 21, 1903.

Application led December 26.1901. Serial No. 87.190. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE I). 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 the object of my invention is to construct a device of this kind in which the bearings for the rolls ymay readily adjust themselves to compensate for the varying positions of said rolls when in use or by reason of any inaccuracies in the frame of the machine.

A further object of my invention is -to provide means for more easily and readily assembling the frame of the machine.

A further object of my invention is to improve in the construction of the rolls to reduce the power required for their operation and also to overcome certain objections.

My invention consists in the constructions and combinations of parts hereinafter vdescribed, and set forth in the claims.

In the accompanying drawings, Figure lis a front elevation of a device embodying my invention shown in position on a tub. Fig. 2 is a perspective view of one of the side frames of themachine with the upper p0rtion thereof broken away. Fig. 3 isa side elevation of one of the side frames with the rolls and their bearings shown in position therein. Fig. 4 is a detail View of a portion of one of the clamps. Fig. 5 is a bottom lview of one end of the apron. Fig. 6 is a perspective view of one of the bearings for the upper-roll shaft. Fig. 7 is a perspective view of an intermediate bearing block for the spring. Fig. 8 is afront View of the upper-roll bearing with the intermediate bearing-block shown thereon. Fig. 9 is a perspective View of the bearing for the lower-roll shaft.

Like parts are represented by similarletters of reference in the several views. j

In the said drawings, a a represent the side frames of the Wringer, which are connected together at the top bythe arch ct and at the bottornby the apron a2, which forms the guide for the clothes in the usual manner, all of these parts being preferably constructed of metal. The side frames a ct are each formed with an opening a?, which opening extends to the top of the frame and terminates near the bottom in a rounded depression a4. On each side of the opening a3, adjacent to the points where the depression begins,are formed supporting-faces a5, these faces being formed on the outer side of each of said side frames. Fitted in this depression 0.4 is the bearing c for the shaft bzof the lower roll b', which bearing is provided on either side of one end thereof with projections c', formed half-rounded on their under sides and adapted to rest on the supporting-faces a5 of the side frames. The other end of said bearing c is provided on each side with a projection c2, 'the respective projections c and c2 forming between them recesses Within which extend the guides ai on the side frame to ,prevent lateral displacement of the bearing.

c3 represent grooves for the reception of oil for lubricating the bearing.

The upper roll b rests upon the lower roll b and is driven thereby byfriction, a spring d being employed to exert pressure upon said rolls in the usual way. The ends of this spring are extended through the respective openings a3 and rest upon supporting-blocks d', each block being formed on either side with a depressionfor groove cl2, within which extend the guides a6 of the side frames to hold said blocksfrom lat-eral displacement. The under side of each of these blocks is formed with rounded bearing-faces d3, and

these bearing-faces d3 rest on the supporting- `faces e of a bearing e for the shaft of the upper roll. The bearing e is provided on either side of the inner end thereof with a projection e2 to engage the guides as ofthe side frame, and thus hold said bearings in proper position in said frame. The bearing e is shown provided with an opening e3 for lubricating purposes.

It will be seen that by providing the block d with the rounded bearing-faces, as described, I provide, in effect, a rocker-bearing for the upper roll, which construction permits the bearings for said roll to assume the constantly-varying positions into which theyare forced by the roll in performing its work-as, for instance, whenvthe upper roll rises atone end owing to the uneven thickness of the material passing between the rolls or to the fact IOO ` bling the frame of the machine, I have constructed said frame so that the lower parts of the side frames may be secured together with- `out the aid of bolts, rivets, or other fastenings of this character. rlo accomplish this, I provide the forward edge of each side frame with a lugj', formed with a depression f', and beneath this lug is a curved projection f2, and beneath this projection the frame is formed with a recess f3. The clamps g are each provided with a rounded end g' and ripper and lower projecting studs g2 g3, the stud g2 being adapted lo i'it in the recessed lugf, the stud g3 extending into therecessf, and the rounded portion g' of the clamp resting against the projection f2. Each end of the apron ct2 is perforated, as shown at a7, and adjacent to each perforation on the under side of the apron is formed a rounded rib d8. In assembIinLr the parts the projection or stud g3 of one of the clamps is inserted through one of the perforations a7 of the apron, and the respective si uds g2 and g3 are then placed in position in the recesses f and f3 of the side frame, the apron being turned at right angles toits norinal position to permit of this. After the studs have been properly inserted in the recesses theapronisswung around toits proper position with relation to the frame, the rib cts thereon engaging with the rounded portion et of the side frame, thus locking the parts together. kBy repeating the operation with respect to the other side of the machine it Will be seen that the respective side frames will be iirmlylocked together at the bottom in amanner which can be readily and easily accomplished Without the aid of bolts, rivets, or other fastenings of this kind. The upper parts of the side frames are then secured to the arch in any suitable manner, preferably by bolting, as shown.

In regard to the feature of the bearing for the upper roll it is obvious that the parts might be modied by forming the bearing e with the rounded bearing-faces and the block Cl with straight faces to rest thereon, although the construction described is-the preferable one. Y

Having thus described my invention, I claim- A p l. In a wringer, upper and lower rolls and their shafts, loose bearings for the upper-roll shaft carried by the side frames of said wringer and having dat bearing-faces formed on its upper surface, a spring to exert pressure on said bearings, and interposed blocks between said spring and bearings, said blocks being provided with recesses to engage the sideframes and with rounded bearing-faces 'at the points of contact with dat bearing-faces ot' said bearings, substantially as specified.

2. In a wringer, the combination with an apron with perforated ends, clamps having oppositely-extending studs, side frames with open bearings to receive said studs, said studs on one side of said clamps also engaging the perforations of said apron, projections on said frames to engage said clamps, and ribs on said apron to engage said frames, said projections and ribs forming the sole means to lock the lower end of the frames together and hold the studs of said clamps in said open bearings, substantially as specified.

3. In a Wringer, the combination with the side frames having oppositely-disposed recesses forming open bearings, and an apron to connect said side frames having perforations in its respective ends, of clamps having oppositely-disposed studs to be received in said bearings and engage the perforations of said apron,`a projection on said frames between said bearings adapted to hold the studs of said clam ps in said open bearings, and ribs near the respective ends of said apron to engage said side frames, substantially as specified.

In testimony whereof I have hereunto set my hand this 19th day of December, A. D. 1901.

GEORGE D. LEEDLE.
