Application filed April 7, 1909. Serial No. 488,436.

To all whom it may concern:

Be it known that l, EDWIN F inrit, a citi zen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Clothes-Wringcr, of which the following is a specification.

This invention relates to a clothes wringer of'that type in which the rollers are driven by inter-meshing gears which do not niaterially vary their position with the rollers as they spread apart or move together under the varying thickness of the articles passed between the rollers.

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character' so as to be comparatively simple and inexpensive to manufacture, reliable and eilicient in use,

`and of durable and substantial design.

With this and other objects in view, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a central vertical section taken longitudinally through the wringer. Fig. 2 is an end view thereof. Fig. 3 1s a vertical transverse section of the wringer. Fig. 4f is a perspective'view of one of the bearing plates :tor the rollers.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawing, A designates the frame of the wringer which consists of end uprights 1 and 2 which are held apart in spaced relation by a top cross piece 3 and front and rear horizontally-disposed vertical plates Z.1c-and 5 adjacent the bottom of the standards. The lower ends of these standards are recessed at 6, and are provided with vertical members 7 fastened to the standards with. their lower ends projecting over the recessed portions of the latter'so as to cooperate with the standards to support the wringer on a tub or other support, there .being clamping devices 8 disposed in the rescrews 9 for clampcesses 6 and operated by The upper ends ing the wringcr in position.

of the standards are provided with vertical f spaced parallel members recesses 10 forming 11 between the upper ends of which the cross bar 3 is disposed, the parts being secured together by bolts 12. Mounted on the frame thus formed, are the upper and lower rollers B and C disposed in parallel relation and yielding with respect to eachother to accommodate themselves to the varying thickness ot the articles to be wrung. The upper roller B consists of a metal tube 1Q of such length that the ends thereof will engage in the lower ends of the guideways formed by the slots 1() in the standards, and the portion of the tube or body '12 oi the roller disposed between the standards, is provided with a rubber or other compressible covering 13. The slots or guideways 10 are closed by bearing plates 111 and 15 secured to the standards 1 and Q, respectively, to thereby form retainers for preventing longitudinal movement of the roller B. 'lhe roller C is also constructed of a metal tubular .body 16 shorter than the tubular body of the upper roller so as to be accommodated between the standards of the frame, and on this body 16 is a rubber or-l other yielding covering 17 which contacts with the covering of the upper roller.

Fitted in the ends of the tube 16 are heads 18 and 19 having peripheral tlanges 20 engaging the ends ot' the tube 16, and which are prevented from rotating independently of the tube by screws 20 or equivalent fastenings passing through the ends of the tube 16 and engaging in the heads, the heads being of thimble form. The heads are provided with gudgeons 2l. centrally disposed and extending through bearing openings Q3 in the standards and reduced at their outer ends 22 to engage in bearings 9A 1n the torni of bosses on the inner faces of the plates 14 and 15, which bosses are set into the adjacent standards of the frame. The head 19.01 the roller C has its gudgeon 21 provided with an extension or stun Q5 for receiving the gear wheel 26 that is fastened thereto by a pin or equivalent means 9.7. The plate 15 has an opening 28 for the stud 25 to pass through, and at one side and above y-pin 32. rihe the upper roller, and this gear wheel 33 meshes with and drives the pinion 26 for the lower roller. The shaft 34, as shown 1n Fig. 1, extends through the roller B from one end -to the other, and is so connected therewith that the roller is free to move up and. down while the gear wheels 26 and 33 are maintained in mesh, the shaft having what may be ltermed a floating movement to provide for this relative movement of the parts. rlhe out/er end of the shaft to which the gear wheel 33 is secured, is reduced to form a shoulder 35 which bears against the inner face of the bearing plate l5, the reduced end of the shaft extending through an opening 36 in the bearing plate. rllhis shoulder 35 cooperates with the gear wheel 33 to prevent longitudinal movement of the floating shaft 34. The inner end of the shaft 34 is formed into ,a bifurcated head 37 to straddle a transverse pin 38 riveted or otherwise secured"V in the extremity of the tubular body 12a."

By means of this connection with the roller B, the same can be rotated by the shaft 34 in all positions of the roller, The shaft 34 is not secured rigidly to the gear wheel 33, but has a slight play about the pin connecting it to the said gear wheel, so that as the roller moves up and down, the shaft may rock upon its bearing 36 so as to follow the movement of the roller without materially changing or aecting the relative position of the gears 26 and 33. The opposite end of the oating shaft 34 is bifurcated, as shown and as hereinbefore stated, and the bifurcation is,

somewhat wider than the diameter of the transversemember or pin 38 so that while the rotation of the floating shaft will necessarily cause a rotation of the roller through the engagement of the flatsides of the bifurcation or open-ended slot with the' said pin, the roller will be free to rock without tending to bend or wear the said pin whether the pin be in ay vertical or other position at the time the rising or falling movement of the roller, occurs. Furthermore, the floating shaft. is inclosed by the roller and its gear so that the wringer is not any wider than wrlngers now 1n ycommon use and there are no projecting elongated hubs or shafts adjacent the driving gearing which will :recessitate the carrying of the o erating crank handle to a point appreciabiy distant from the side of the frame. loatin shaft,l furthermore, facilitates the assemb ing and disassembling ofthe parts, inasmuch as after the side plate 15 has been removed a longitudinal movement of the gitudinal movement of the bar 39.

The construction of the shaft will separate the roller from the shaft,

as the open extremity of the bifurcated end of the s aft will move readilyipast thediametrical pin 38. Obviously the parts can be as readily reassembled.

A tensioning device is employed for main-4 70 taining the rollers in cooperative relation, and this device comprises, inthe present instance, a movable cross-bar 39 having its v ends freely movable in the guideways or slots 10 of the standards, and the endsy of 75 this cross-bar are recessed at 40 for accommodatin the anti-friction wheels 4l mounted on ax es 42 in the said bar, with the lower portions of the wheels bearing on the ends of the roller B that project beyond the ends 80 of the rubber covering 13 thereof. 4The opposed faces ofthe fixed and movable cross bars 3 and 39 are provided with alining recesses 43 forming seats for the ends of compression springs 44 which, by the combined 85 eect, produce a great tension on the wringer rollers. Each spring 44 is inclosed in aj tubular housing or sleeve 45, the ends of Y which extend into the recesses 43 so as to thereby form guides for the springs, the 9o sleeves being of suc-h length as to permit of unrestricted umovement of the cross bary 39 toward the fixed cross bar 3.

'llhe sleeves 45, by engaging in the sockets of both cross bars, prevent the niovabl'e- 95 cross bar from longitudinal displacement. In the present instance, the bearing plates 14 and l5 extend upwardlyv far enough to form additional means for preventing lon-V springs 44 are so placed as to exert a substantially equal pressure at both ends of the upper roller by means of the wheels 41 ,which bear directly on the upper roller.

lln ractice, the crank 30 isl operated for 105 simultaneously turning the rollers to wring thearticles in the usual manner. As the rollers are turned, they canl freely move apart or togeher to accommodate the thickness of the articles passing between them,

and at the same time exert a substantiallyl uniform pressure on the article. As the upper roller moves away from the lower roller, the shaft 34 will tilt and the springs 44 will be compressed, because of themovement of the cross bar 39 with the roller,I but the movement of the shaft 34 does not, in any way, v-affect the intermeshing of the gear wheels 26 and 33, and the same is true when the upper roller moves downwardly to its 12o normal positionl From the foregoing description, ltaken 1n connection with the accompanying drawlng,

the advantages of the construction and of the method of operation will be readily ap- 133 parent to those skilled in the art to which the invention appertains, and while I `have described the principle of operation of the The 100 invention, together with the apparatus which and that such changes may be made when, desired, as are within the scope of the claims appended hereto.
