BRUSH CONSTRUCTION.

Application filed February This invention relates to improvements in brushes of the ordinary cleaning type, and particularly to the mounting of the bristles in their holders or supports.

The principal object of my invention s to secure the bristles so that they are positively and firmly held in place in the holders without the use of glue or cementitious material of any kind being necessary. Each set or row of bristles is mounted in an individual holder, an arrangement which of course provides a very narrow brush area.

A further object of the invention therefore is to provide means for readily connecting as many holders together as may be necessary to form a brush of any desired width, in such a manner that the complete brush structure will be very light compared with the area covered by the bristles so that the brush will be very easy to handle.

A further object of the invention is to produce a simple'and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a perspective elevation of a brush formed with a single bristle holder.

Fig. 2 is an enlarged cross section on the 0 line 22 of Fig. 1.

Fig. 3 is a perspective elevation of a brush bu lt up of a number of holders spaced transversely relative to the plane of the handle.

Fig. 4 is a fragmentary enlarged cross section on the line lt of Fig. 3.

Fig. 5 is a perspective elevation of a brush built up of a number of handles, spaced longitudinally of each other relative to the plane of the handle.

Fig. 6 is a perspective view of a griddle greaser utilizing my improved bristle mounting means.

Referring now more particularly to the characters of reference on the drawings, the bristle holding feature of all the brushes is the same and comprises a metal plate 1 of deep Ushaped cross section. The bristles 2 are disposed between the sides of the plate from end to end thereof to form a row,

each bristle being also bent double in U-shaped form and of course projecting outwardly of the plate a certain distance, depending on the type of the brush. The bristles are held in place by a wire 3 which is inserted between the two le s of each bristle member at the bend thereof, and after this is done the sides of the plate are pressed firmly together beyond the wire, as indicated in Fig. 2. This of course prevents movement of the wire from its location in the plate, and prevents the bristles from dropping out. Since this pressure when thus applied to the plate also clamps the bristles between the wire and plate said bristles cannot pull out. A brush thus constructed should therefore last indefinitely, since the bristle holding means is of such a nature that there is no tendency for it to rot or disintegrate, as is the tendency with the brushes in which the bristles are glued or similarly secured in place. Manufacturing operations may also be much more quickly and easily carried out.

Each holder with a complement of bristles and the wire 3 therein lends itself readily for assembly with other holders to form brushes of various sizes.

In Fig. l I have depicted a brush of a narrow type, suitable for certain uses and utilizing a single holder and a corresponding number of bristles. In this type the plate member 1 is merely extended beyond the bristle holding area to form a handle 4: of any desired length.

In Fig. 3 I show a brush of typical clothes-brush form, and in Fig. 5 a brush of the sweeping type. To connect the requisite number of holders together in either type I merely extend the wires 3 beyond the holders a certain distance at both ends, as shown at 5 in Fig. l. These extensions are then inserted and clamped between the sides of cross plates 6 similar in form to the holder plate 1, and the wire extensions then bent down so that the plates 6 rest vertically across all the holders at their ends, as shown in Figs. 3 and 5. The various parts may then it necessary be soldered together at various points to prevent the movement of the holders relative to each other and to hold the cross plates against movement relative to the wires clamped therein and to the holders as well. A wire handle 7 of suitable type to extend longitudinally of the holders may be Ill) readily connected by solder or the like to certain ones of the holders in the type of brush shown in Fig. 3.

In the type of brush shown in Fig. 5 a number of wires 8 preferably converge toward each other from various points on the outer bristle handles to form a handle 9 extending in upward direction and at a suitable angle. This arrangement adequately braces the relatively large bristle holding structure to the handle.

In Fig. 6, I hare shown the bristle arrangement as applied to a griddle greaser of the general type shown in my Patent No. 1,612,- 926 dated January eth, 1927. This greaser comprises an inverted cup 10 having a handle 11, with the plate member 1 holding short bristles 2 bent in the form of a ring to fit inside the cup.

From the foregoing description it will be readily seen that I have produced such a device as substantially i'ullills the objects of the invention as set lorth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit 01" the invention, as defined by the appended claims.

Having thus t cscribed my invention what I claim as new and useful and desire to secure by Letters-Patent is:

1. A brush comprising a plurality of spaced b 'stle holding members, wires projecting from the ends of said members, and means supporting and securing said wires at their ends to maintain the members in fixed spaced relation to each other.

2. A brush comprising a plurality of separate elongated bristle holding members spaced apart, wires projecting from the ends of said members, and plate members of U-shaped cross section extending across the ends of the holders and between the sides of which the ends of said wires are secured.

3. A brush comprising a plurality of separate and spaced holding members, bristles projecting therefrom, plate members across the ends of the holding members, and a common means securing the bristles in the holding members and connecting the latter to the plate members.

In testimony whereof I afiix my signature.
