BRUSH-BRIDLE.

Application filed November 30, 1914. Serial no. 874,837.

To all whom it may concern Be it known that T, GILBERT 0. Burns, a citizen of the United States, residing at VVorcest'er, in the county of Worcester and State of Massachusetts, have invented a new and useful Brush-Bridle, of which the following is a specification.

This invention relates to a bridle for a brush and although capable of general use is particularly adapted for a stiff bristled brush having a relatively large area over which the bristles are distributed, and especially for brushes having metal bristles.

The principal objects of the invention are to provide a bridle entirely surrounding the body of bristles and especially to provide a construction in which the bridle can be formed of two wires secured to the body of the brush at the ends thereof instead of at the sides, and to provide a simple, convenient and inexpensive means for securely holding them in position at the ends of the brush.

Reference is to be had to the accompanying drawings in which Figure 1 is a side elevation of a brush constructed in accordance with this invention; Fig. 2 is an end elevation thereof Fig. 3 is a sectional view on the line of Fig. 2; and Fig. 4.- is a bottom plan.

The invention is shown as applied to a brush for use in cleaning meat-blocks. This brush comprises a solid back 10 and a plurality of rows of flat wire bristles 11. Ordinarily in the manufacture of brushes of this and similar kinds, the bristles are arranged.

as near as possible to the sides of the brushback so that there is no convenient place in which to secure a bridle, and for this reason I have provided for-securing it at the ends but it is to be remembered that the end bristles are the ones which are most fully protected by the bridle, and consequently the bridle should extend along all the end bristles and have its full strength and efiiciency clear across the end of the brush.

The bridle preferably is made mainly of wire. Two wires 13 are shown alike in all respects, each having a horizontal main part, a transverse member or arm 14 at both ends and a vertical sharpened end or leg 15 transverse thereto adapted to be driven into the body of the brush just at the ends thereof. These horizontal bends 14 of the two wires are in the same place at each end and also in Patented Sept.

direct alinement with each other. i F or the purpose of securing them together, although they are located at a distance apart, astrip' of sheet metal 16 is provided having two notches 17 along of the long edges. The unnotched long edge is bent inwardly over the two horizontal members 141 until it engages the inner surfaces of the vertical ends 15. The opposite notched edge is bent downwardly around these members 14L and comes into contact with the unnotched edge mentioned. The two notches are spaced just farenough apart to receive the tops of the fastening ends 15. *When this is secured.

force the wire members to the same positions on all the brushes, and at eachend of each brush, so as to insure that all the bridles shall be uniform in shape and size. In this way the bridle is caused to surround the entire body of bristles and present a strong, smooth surface at the ends, a d furthermore the joint'between the two edges" of the member 16 is entirely hidden by being located on the inner side neXt the bristles, and it is firmly and securely fixed without the necessity of employing skilled workmen to place it properly in position.

Another feature of importance lies in the fact that the cylindrical member 16 is larger in diameter than the wire of which the rest of the bridle is made. Consequently the end bristles engage a wider surface and there is little danger of their being bent over at an acute angle. This tends to keep them straighter than in those cases in which only a small wire is used to resist the bending of the bristles.

. Although I have illustrated and described only a single form of the invention and shown it as applied only to a single style of brush, I am aware of the fact that many modifications can be made therein by any person skilled in the art, and that it can be applied to other types of brushes without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described,

nor to the particular kind of brush illustrated, but Q What I do claim is 2-"- 1. As an article of manufacture, a brush bridle comprising two wire members each having a main body portion adapted to extend along the body ofbristles of the brush at the side thereof, and arms bent inwardly at both'ends in the sameplane, and means in the plane of said arms for fastening the I said arms together.

52; As an, article of manufacture, a brush bridle comprising two wire members each havin a main body portion adapted to extend along the body of bristles of the brush at the sidethereof, and arms bent inwardly back-for fastening the said arms together.

I 3. As an article of manufacture, a brush bridle having a air of, legs spaced apart at .each end of the 'ody of bristles, secured in the'brush back, and extending I normally j from the plane. thereof, said legs being bent outwardly in oppo'site directions at their extreme ends to form arms in alinement with each other and then being bent again at right angles in the plane of said arms to form main body portions parallel to each other, '.anda tubular member surrounding said arms and connecting said legs together. 4. As an article of manufacture, a brush bridle comprising two wire members each having arms bent inwardly, the ends of said arms being bent at right angles to form legs to permit of fastening the same to the brush back, and means for fastening the said arms together, said means consisting of a hollow sheet metal member surrounding said arms separated along one side and having apertures at the edges for receiving the tops of said legs.

5. As an article of manufacture, a brush bridle having a hollow cylindrical sheet metal member at the end for engaging the bristles and holding the parts of the bridle in position, said member throughout part of its length substantially surroundinga part of the bridle.

6. As an article of manufacture, a brush bridle comprising two wire members each having a main body portion adapted to extend along the body of bristles of the brush at the side thereof, and arms bent inwardly at both ends in the same plane, the ends of said arms being bent at right angles to that plane to form legs to permit of fastening the same to the. brush back, and means at both extremities for fastening the said arms together, said means consisting of a hollow sheet metal tube surrounding said arms and having apertures for receiving the tops of said legs.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
