Specification of Letters Patent.

Patented J une 13, 1916.

Application filed September 28, 1915. Serial No. 53,003.

To all whom t may concern:

Be it known that I, WILLIBALD TRINKS, a citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Tashing-Machines, of which the following is a specification.

My invention consists in certain new and useful improvements in rotary washing machines, more especially relating to means for preventing the garments or other washing from becoming wrapped or twisted about the backing roll which serves to hold the garments against the rotary brush during the washing operation.

More particularly, my invention comprises a stripper blade resiliently held against the face of the backing roll and carried by the mounting of said roll, so as to move in unison with and bear constantly against said roll.

Other novel features of construction and arrangement of parts will appear from the following description. A

In the accompanying drawings, Figure l is a side elevation of a washing machine embodying my invention; Fig. 2 is a broken partial plan view of the same, Fig. 3 is a broken elevation showing the stripper lblade dismounted, and Fig. 4 is an end elevation of the same with the mounting thereof shown in dotted lines.

The following is a detailed of the drawings.

A represents one of the ends of the washing machine frame, the two ends being similar in design, and having journaled between them the rotary washing brush B provided with radial bristles l. Said brush is powerdriven, but as the method of applying rotary movement to the brush is not ya part of the present invention, the same is not shown.

C is the backing roll held resiliently against the brush B, the ends of said roll being. supported from the frame in the following manner. As both ends of the roll are supported in the same manner, Ilwill describe the mounting of one end as characteristic.

2 is a depending link whose upper end is pivotally secured to the upper portion description of the frame A and whose lower end is pivotally secured to the outer end of a rod 3. which extends through a hole in the vertical tlange et of the frame and has its inner end threaded to receive a washer and nut 5. A helical spring G is mounted on the rod 3 between said iange and said washer, the tension of which spring may be adjusted by means of the nut.

The axle ends 7 of the roll C are journaled 1n sockets or boxes 8 on the inner faces of the links 2 intermediate of the ends of the latter. It is evident that by this means the backing roll is held resilientlyl against the rotary brush with a force which may be adjusted by regulating the nuts on the inner ends of the rods 3. The backing roll may be forced away from said brush to permit varying thicknesses of garments to pass through the machine, the two ends of the roll being enabled to move independently, owing to their individual mountings.

D is the stripper blade, having an upper beveled edge which fits fiat against the face of the roll C below its line' of contact with the rotary brush. The ends of said blade are riveted or otherwise secured to the upper arms of angle brackets E which are pivotally'connected at their angles, as by means of bolts 9 to brackets l0 on the lower ends of links 2. The lower arms of the angle brackets E are provided with seats to receive and contain the lower ends of helical springs ll whose upper ends bear against the projections 12 on the inner faces of the links 2. Y

It is thus evident that the beveled edge of the blade D is held resiliently against the face of the roll C at all times, as the blade is mounted in unison with said roll and moves therewith at all times. of the roll is of hard unyielding material, so that it does not become grooved by contact with the brush bristles, so that no circumferential depressions appear which might catch the garments, nor can buttons or other hard articles carried by the garments sink into the surface of the roll and' thus enter under the stripper blade.

Should, however, a garment gain entrance between the roll and the stripper, no injury to the garment will result, as the mounting of the stripper is outside of the ends of the The surface Iresiliently against roll, out of the way of the garments, and a smooth, regular surface kis presented. The stripper is heldin constant contact with the roll throughouty its length, so that as the stripper in time wears down, its` edgey will always be kept in close contact with the roll.

As the washer yis intended to be powerdriven at considerable speed, it is evident that my improved stripper is of ,great value in preventing accidental stoppage of the machinery and destruction ofY garments. i

What I desire to claim is- 1. In a washing machine the combination of a frame, a rotary brush roll journaled in said frame, a swinging support mounted on said frame, a backing roll journaled in said support" and held resiliently against said brush roll, a stripper blade having itsk ends journaled `in said swinging support, Vand springsv connecting said blade "7 with vsaid swinging support where-by said blade is held the surface of the said backing roll,y as and for the purpose set Y forth.

Y 2. In a washing machine the combination of a'frame, ,av rotary brush roll journaled in saidy frame, a pair of links pivotally atvsaid links, whereby is held resiliently against the surface of said f springs interposed tached at their one ends to said frame, a backing roll having its ends journaled in said links and held resiliently against said brush roll, a stripper blade having its ends journaled in said links, anda spring connecting each end of said blade with Vone .of the edge of said blade backing roll, as and for the purpose vset forth. f Y

3. In a washing machine the combination of a frame, a brush roll journal'ed in said frame, a pair of links pivotally attached at their one ends to said frame, a backing roll having its ends journaled'in said links intermediate of the'ends ofthe latter and held resiliently against said brush roll, a strip- Yper blade having its ends journaled in said links Vadjacent to the free ends of the latter, angular brackets on said stripper blade, and between said brackets and said links Whereby'said'blade is pressed resiliently against the surface of Vsa'idbacking roll, as and for the purpose set forth.

Signed at Pittsburgh, Pa.this 24th day of September, 1915. WILLIBALD TRINKS. i
