WRINGER.

Application filed July 21,

To all whom it may concern:

Be it known that I, BYRON A. WALKER, a citizen of the United States, residing at Erie, .in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Wringers, of which the following is a specification.

Clothes wringers have been formed of wood frames and with metal frames. In some respects the wood frames are more desirable than the metal frames as screws hold in the wood much better than in metal, the slight elasticity of the wood adding to this efiect. It is also much simpler to attach the wood frame Wringer to the various wringer supports as they are found on modern washing machines as practically every washing machine has a variation in the support which variation must be met by the wringer structure. On the other hand the metal wringer corresponds more nearly in appearance and structure to the general structure of the power washing machines particularly and is stronger and more resistant to certain features of use than the all wood frame wringer. In the present invention it have combined the two materials retaining the desirable features of both. It also permits of the forming of the wooden portion of the wringer in a very much simpler and efficient manner.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a front elevation of the wringer.

Fig. 2 a side elevation.

Fig. 3 a top view of one of the stiles with a bearing in place.

Fi 4: a longitudinal vertical section on the lines 4-4 in Figs. 2 and 3 through the center of the wringer.

Fig. 5 a cross section on the lines 5-5 in Figs. 1 and 3.

ig. 6 a cross section on the lines 6-6 in Figs. 2 and 4.. I

1-1 mark the stiles. These stiles are formed with wooden insides formed with'a block 2 at the bottom which is nearly the full width of the stile and the uprights 3 projecting in a line with the outer faces of the block 2 and forming between them the vertical guide groove t. This simplifies the construction materially from that commonly used in woodwringers in which the part 2 must be made integral with the parts 3, and

1921. Serial No. 486.362.

Pressure springs 9 rest on plates 10, the

glates resting on the upper bearings 6. crew plates 11 rest on the upper ends of the spring and tension screws 12 operate on these plates, the tension screws being carried by the top bar 13. A bracket 14 bridges the space across the top of the slot 4 and is secured to the side walls of the stiles by screws 15 which extend into the wooden insides.

The bracket has a lip 16 on its upper edge under which the top bar 13 extends. The top bar is formed of two parts 17 hinged at 18- and having the abutting ends 19. A shoulder 20 is caught by the latch 21 holding the bar normally in its rigid position but upon the release of the latch releases the top bar so as to release the rolls in the manner described in the patent to N. B. Hutton. #1,13a,122, May 11. 1915. The structure so far described is similar to wringers already made.

I provide a sheathing 22 for the stiles. The sheathing is preferably in the form of channels, one channel at the front and one at the back of each stile, the. flanges of the channel overlapping the inside and outside edges of the stiles. This sheathing is secured to the stiles by screws 23 at the top and by the screws 24 at the bottom, the screws-24 overlappii-g so as to prevent the splitting of the block 3 between the slot 4 eneral and the slot 25 and the slot 25 in place thereof adapts the bottom of the stile to a wrin er support as 26. I prefer to carry the c annels across the top at 27 so as to house the top of the stiles as well as the sides. splice the guide strips 3 and the block 2 It will be noted that these channels holding the guide strips rigidly in relation 'a closer and smoother rately so that the guide wooden stile 1n which'the'two strips are-integral with the bottom block. It will be noted that the'screws of the bracket 14 not only extend through the bracket but also through the metal sheath into the wooden inside. In this way the brackets may be very economically and very securely mounted.

Connecting plates 28 extend from stile to stile, the screws 29 extending through these connecting lates, throu h the sheathing or metal re-enibrcements o thewooden inside into the wooden inside itself. the resilience of the wood yielding under'pressure of the screw thus assuring a spring-pressed clampin en agement between the plates and the en d sti es.

Guide plates 30 are arranged opposite the rolls and are secured to the end stiles by screws 31 which extend through the plates and the sheathing or re-enforcing channel plates of the stiles into the wooden insides thus making a secure union of these parts.

A guard plate 32 is arranged over the gears 7 secured to the end stiles by the screws 33 which extend through the sheathing into the wooden insides and the screw 3 which extends through the guardplate directly into the wooden inside.

A screw extends through the wooden inside between the sheathing plates and has a projecting end 36 which extends into a slot 37 of the drain board.

The end stiles are clamped by a bolt 39 on a wringer support the wood inside permitting of a convenient forming of the 'wringer and adapted to the support and also springing slightly to assure a perfect engagement of the Wringer with the suport. p With this structure the wringer in appearance is a complete metal wringer. The connecting parts are united by wood screws with the superior holding quality over metal to metal holding. The guide ways for the bearings are formed in wood and thus in a. convenient manner house the springs and bearings. The guide-ways are more accurate and uniform than? s practical where the slots are cut out from an integral piece of wood and there is a considerable saving of material. The metal sheathing splices the wood parts and thus makes possible the formation of the guide strips and bottom block in separate pieces and at the same time protects that part of the wood which is most exposed from the direct action of water and thus prolongs the life of the wringer. Further the shapes of the guide ways may be varied as the bearings vary or spring constructions vary so that in a very simple way thest-ructure lends itself to the varying connecting .parts of the wringer.

It will also be noted that the sheathing forms a facing for the ends of the securing bolt 39. In the operatidn'of the wriuger this bolt 'is under considerable strain. and the facing on the wood helps in sustaining this strain and at the same time the elasticity of the wood assists in maintaining a firm engagement.

\Vha-t I claim as new is 1. A wringer stile formed with a wooden inside having a bearing slot therein, and

- bearing slots extending from the top thereof and metal sheaths forming housings for the insides: brackets bridging the tops of the slots; and means extending through the brackets and the sheaths into the wooden insides for securing the brackets to the stiles.

4. A wringer stile formed with a wooden.

inside comprising a. bottom block and. upwardly extending guide strips to-rined separately from the wooden block; and rigid metal plates splicing the block and strips.

5. A wring-er stile formed of a wooden inside com'prising guide strips projecting upwa'rdly from'a supporting block forming a guide slot between the strips; and a metal sheath comprising channels placed over the front and rear walls of the wooden inside. said channels splicing the block and strips. In testimony whereof I have hereuntoset my hanil. 7
