STEEL-WIRE BRUSH.

SPECIFICATION forming part of Letters Patent No. 511,356, dated December 26, 1893. Application filed October 18, 1893. Serial No. 488,497. (No model.)

To all whom it may concern.-

Be it known that I, FRANK PAQUET, a citizenof the United States, and a resident of Hamilton, in the county of Butler and State 5 of Ohio, have invented certain new and useto object is to prevent the end tufts of wire from breaking off near the brush back.

In use, the brush is held in the hand and the operator strikes it endwise back and forth over the rough castings to free them from [5 sand and scales that adhere after they leave the mold, and the end bristles being unsupported, by the constant vibration in use, causes the metal to crystallize and the flat steel wires to break off, rendering the brush useless in a short time; whereas,-the central tufts being supported by each other, last much longer.

Theinvention will be fully understood from the following description of the accompany- 2 ing drawings, in which- Figure 1 is a side elevation of a brush constructed according to my invention. Fig. 2 is an end view of the same with the bristles omitted. Fig. 3 is an inside edge elevation of c the preferred form of end support shown at the right hand sideof Fig. 1. Fig. 4 is a vertieal section of the same, taken through line a w of Fig. 3. Fig. 5 is a similar section of the modified form shown on the left hand side 3 5 of the brush, Fig. 1. Fig. 6 is the blank on which the end supports are formed.

The brush block A, with its back A, and the wire bristles B, are of the usual construction and need not, therefore, be specifically described. The preferred form of support 0 is formed up of the sheet metal blank, Fig. 6, the sides a and the back 0', together forming the open box into which the end of the brush body A is inserted after the wires have been properly put in place. The sides 0 have inturned ends 0 which lap under the back of the brush, and the back portion 0' has an outwardly turned portion 0 which extends down to the end of the brush bodyA and has an inturned end 0 which passes under the brush body and over the inturned ends 0 After the box or support 0 is placed in position over the end of the brush body A, the cap A is secured to the brush body A in the usual manner.

The form of support 0, shown at the left hand side of Fig. 1, and in vertical section in adapted for application to brushes Fig. 5, differs from the usual form in that the inturned portions 0' and c are omitted, and the support 0 secured on the brush by screws or rivets d. This form is not so strong and durable as that shown in Figs. 2, 3 and 4, and the right hand side of Fig. 1, but it is better already manufactured, and accomplishes the same result.

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

1. The combination of the brush body A, wire bristles secured therein, and the sheet metal box 0 fitting over the end of the body and having its ends turned in between the body and back of the brush, substantially as shown and described.

2. A new article of manufacture, a sheet metal box adapted to fit over the end of the brush and bear against the end tufts of bristles, and having its rear and side walls extending down over the ends and sides of the brush, to be secured thereto,substantially as hereinbefore set forth.
