IMPROVEMENT IN FLOORSCRUBBERS.

Specilieation forming part ol' Leiters Patent No. 206,?2E2, dated .luly Q3, 1878; application filed April 5,1878.

To all whom it may concern:

Beit known that I, FREDERICK A. BALCH, of Hingham, in the county of Sheboygan and State of Visconsin, have invented a new and useful Improvement in Floor-Scrubbers; and that the following is a full and clear description of the same, having reference to the accompanying drawing, wherein- Figure l is a perspective ot' my improved scrubber with the brush in action. Fig. 2-'is a perspective view ot' the same, showing the rubber in action. Fig. 3 is a transverse section, showing the action of gathering' the water from the door.

In scrubbing iioors, ciiiciency requires the use of. both brush and rubber and means for ready removal 0i the free water t'rom thc licor.

My implementv is designed to obviate the necessity of kneeling upon the licor and the employment of the traditional soap and sand with the haiul-brush, and also the tedious process of removing the free wa ter with the mop-cloth; and to that end I have, in the same implement, (mounted upon the end of a suitable handle,) combined a scrub-brush and a rubber, of india-rubber or other suitable material, with a waterpan, within which nearly or quite all the free water maybe gathered from the tloor.

I am aware that scrub-brushes have `heretofore been mounted upon handles, and also that rubbers of india-rubber have also been so mounted; but I am not aware ot' a brush, rubber, and water-pan combined in one structure and mounted upon the same handle. I believe, also, that the structure ot the several part-s is new.

That others may fully understand my improvement, l will particularly describe it.

A is the brush, with-the tutts of bristles set therein iu the usual way. One edge ot the back ot' A is wider than the other, to facilitate the attachment of the scrubber-back C, which is secured to the brush-back by screws. One edge of the back of the brush A extends down over a portion of the rubber strip, securely holding it in place.

A rabbet is made in the scrubber-back C, on one side, for the reception of the scrubber l), which consists ot' a strip ot' vulcanized india-rubber, or other suitable material, and a rib, d, is made longitudinally along the eentra-l part of the opposite side of said back C. This rib is for the purpose ot strengthening the back and offering a strong abutment for the pivot-pins c c, whereby the backs bA and C are attached to the water-pan F and block G, into which the handle l1 is inserted.

`The water-pan F is constructed of galvanized sheet-iron, or other suitable material, folded and bent so as to form two sides and two ends of the water-pan, as shown. The front edge is made straight and close a gainst the side of the rubber strip or scrubber I), and thereby forms a. tight joint.

The end parts of the back are nailed to the block Gr, which gives it strength and stittl ness, and is provided with a socket for the end of the handle Il.

Two strong spiral springs, I l', placed between the back edge ot' the block G and the edge ot' the back C, keep the whole structure iirm and the front edge of the waterpan F tight-ly closed against the rubber strip l); but said springs may be caused to yield by a backward movement of the implement with the edge ot' the scrubber pressed hard down upon the floor. The pan F is thereby opened, so that the water accumulated behind the rubber, bythc movement described, will be caused to flow over into the pan, as shown in Fig. il.

rlhe cessation ot' the pressure described will cause the pan to close, and the water will be retained.

The hole serves i'or the discharge otl the inclosed water in the bucket or other reccp tacle.

lhe ordinary use of the scrubber or rubber is by pushing, and that movement tends to close the pan more tightly against the rubber l); but a pulling backward, together with. a. downward pressure, has the effect of opening the pan and causing the water to ilow in, as above described.

Havingdescribed my invention, whatl claim as new is- 1. The brush A, with one edge of its back ext-ended, as described, and the rabbeted back provided with :1 rib, d, and rubber D, comproieetng from another side, wml Smtwle bined with the pvoted winter-pan F, subsprings to close the edge of said pan against stantially as set; forth.. the rubber, es set forth.
