FREDERIC L. CLARKE, OF GLENS FALLS, NEW YORK, ASSIGNOR TO THE CLARKE MANUFACTURING COMPANY, OF SAME PLACE.

BRUSH-WIPER.

SEEGFICATION forming part of Letters Patent No. 541,224, dated June 18, 1895. f

Application tiled January 18, 1895. Serial No. 535,350. (No model.)

To all whom -zit may concern.:

Be it known that I, FREDERIC L. CLARKE, a citizen of the United States, residing at Glens Falls, county of'Warren, and State of New York, have invented certain new and useful Improvements in Brush-lVipers,V of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a central vertical section of a mucilage-bottle, showing a brush, partly in section and partly in elevation, supported by the handled cover, and the brush-wiper mechanism, shown in vertical section, taken on the broken line l 1 in Fig. 2. Fig. 2 is a bottom plan View of the wiper mechanism detached. Fig. 3 is a vertical section of the wiper mechanism, taken on the broken line 3 3 in Fig. 2. Fig. 4 is a side elevation of one of the wiper-plates. Fig. 5 isa plan view of the partly-formed wiper-frame.

A represents a mucilage bottle; A-, a brush; A2-, a cover for the bottle and asupport for the brush, and A3- a handle for the cover and brush, all made in the usual well known manner.

The brush-wiper mechanism comprises a supporting frame 13.- which may be of sheetmetal, out and swaged by suitable dies to form the annular depending peripheral flange B- adapted to inclose the top of the bottle and secure the frame thereon.

The peripheral depending ange may be integral with the frame or a separate ring soldered or otherwise secured to the frame body.

The frame-bodyhas the general form of a disk, the middle portion being cut away, as shown in Fig. 5, to form a rectangular opening B2- and the slits B3 and B4 projected from the middle opening toward the peripheral edge of the disk and terminating at points in the lines of another rectangular gure represented by the dotted lines B5- and BG- in Fig. 5, the lines B4- being approximately radial to the disk and extending to the corners of the dotted rectangular figure.

By bending at the dotted lines B--and B6- the four triangular portions B7- of the disk,

formed by the slits, down approximately at right angles to the plane of the disk, as shown in Figs. l and 3, I form the hangers for the wiper-plates C- and C-.each of which is provided at'each end at or near its upper edge, with a trunnion C2 adapted to enter and have its bearing in the aperture B8- formed in the adjacent triangular hanger 137-.

The lower edges of the wiper-plates are parallel with each other and oscillatory to and from each other. The oscillatory movement of each wiper-plate is controlled by a spring S- one end of which is secured to the diskbody or frame as by solder S- and the other end SL- bears upon the wiper-plate. The springs tend to force the lower edges of the wiper-plates into engagement with the brush inserted between them as shown in Fig. l.

When the brush is withdrawn, the normal position of the lower edges of the wiper-plates is in engagement with each other, as shown in Fig. 2. As a means for maintaining such normal position in the middle vertical plane of the apparatus and midway offthe 'vertical planes cutting the trunnion-bearings of the respective wiper-plates, I bend along the dotted lines B5 the rectangular shaped parts B9- down to the position shown in Fig. 3, to form stops for the wiper-plates, to limit their oscillating movements toward each other, whereby they are each prevented from passing the middle vertical plane. The parts B10- may also each be slightly bent along the dotted lines B6- to incline downwardly and overhang the upper edges of the wiper-plates, whereby any drippings from the brush, as it is withdrawn from the wiper-plates, are prevented from coming in contact with the springs to impair their action.

The operation of the apparatus is as follows: The brush is inserted in the bottle by pushing it down between the yielding wiper-plates which are forced apart as shown in Fig. 1. After the brush has filled with mucilage or other contents of the bottle,.it is withdrawn,

IOO

and the wiper-plates being forced by the springs against the brush at their lower edges, Wipe off the superiiuous mucilage adhering to the outer surface of the brush, and permit it to drop back into the supply beneath.

The .tension of the springs can be varied for varying uses, whereby more orlessof the fluid deposit on the brush can be'removed as desired.

My improved apparatus is adapted for use with paint brushes, whitewash brushes or other brushes supplied by dipping, and can be applied to bottles, cans, pails or other Huid receptacles.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a brush-wiper, the combination with a supporting frame, and means for sustaining the frame upon the mouth of a fluid receptacle, of a pair of movable spring-actuated wiper-plates, and a stop for limiting the movement of the plates, substantially as described.

2. In a brush-wiper, the combination with a supporting frame, and means for sustaining the frame upon the mouth of a Huid re- 25 v ceptacle,of a pair of movable spring-actuated wiper-plates, and an overhangingguard-plate above each wiperplate, for protectiugits actuating spring, substantially as described.

3. In a brush-wiper, the combination with 3o l a pair of oscillatory, downwardly-converging spring-actuated wiper-plates, of a plate-supporting frame formed from an integral plate of sheet-metal with depending hangers containy ing bearings for the Wiper-plates, and a stop for 3 5 FREDERIC L.
