Patented Sept. 25, 192d.




This invention relates to brushes, such as hair brushes and the like and especially to a brush in which the bristles may be removed for cleaning, sterilizing, etc., to insure sani- 5 tary conditions.

The object of the present invention is to generally lHlPiOX'C and simplify the construction of brushes; to provide a brush embodying a handle and a head member, said head member being longitudinally slotted for the reception of a removable bristle bar; to provide a bristle bar constructed of metal in which the bristles are arranged in row formation and rigidly secured and clamped; to

1 provide a bristle bar of this character which may be readily cleaned or sterilized to insure sanitary conditions; and further to provide a simple form of locking mechanism whereby the bristle bars are rigidl secured against removal when inserted 111 t e head of a brush.

One form which the invention may assume is shown by way of illustration in the accompanying drawings in which:

. Fig. 1 is a perspective view of a brush showing a number of bristle bars removed,

Fig. 2 is a perspective view of one of the bristle bars,

Fig. 3 is a detail sectional view of a portion of the brush head, showing the resilient latch,

Fig. 4 is an enlarged cross-section on line IVIV, Fig. 2,

' Fig. 5 is a cross-section of the head of the brush, showing a modified structure.

Referring to the drawings in detail and particularly Figs. 1 and 2, A indicates the head of a brush and B the handle. Formed on the head of the brush is a plurality of grooves such as shown at 2 and insertable 4o endwise in the grooves are bristle bars. such as shown at 3 (see Fig. 2). The bfottom portion of each groove is rounded out and enlarged as at 2 to receive the head 3" of each bristle bar, the head members 3 securing the bristle bars against removal in one direction while the locking bar 5 secures the bristle bars against endwise' removal. The locking bar 5 is hingedly secured to one side of the brush head as indicated at 6. Its opposite end is slotted as at 6 and is adapted to interlock with a resilient spring latch, such as shown at 7 (see Figs. 1 and 3). The bristle bar proper is preferably constructed of sheet metal, such as aluminum or the like. It coni sists of an elongated strip bent upon itself Application filed October 26, 1927.

as shown in Figs. 4 and 5 to form an elongated double wall bar. The upper edge of the bar is perforated as indicated at 8 to'permit the bristles t to extend t-herethrough. A wire rod Q'CXtEDClS between the double walls of the bar along the lower edge and the bristles are bent around the bar. The sides of the bar are then pressed together so as to rigidly clamp and secure the bristles, and a head member a is thus formed.

A brush provided with grooves such as shown and removable bristle bars can be quickly and readily cleaned and sterilized whenever desired, as it is only necessary to release the spring latch 7 and to remove the bristle bars endwise from the grooves 2. lu'ach'bar may then be thoroughly washed and sterilized, then replaced, thus insuring sanitary conditions. Attention is directed to the fact that the bristles pass through perforations in the liar and not through slots, and furthermore, that the space within the bar accommodating the bristles will be completely sealed by the back of the brush, thus maintaining the bristles and their bars in a sanitary and easily cleanable condition. While the bristles are secured by pressing the side walls of the bar together and by looping them around the wire rod, it is obvious that cementitious material may also be employed, if desired. The head of the brush may be constructed of any material desired, such as wood, vulcanized rubber, celluloid, etc. In some instances it may be desirable to construct the head of the brush partiall of m eta1, for instance a metal sheet may be ent as shown in Fig. 5 and secured to the sides of the head. Metal channels 2 are thus formed into which the bristle bars are inserted.

While other features of the present invention are more or less specifically described, we wish it understood that various changes may be. resorted to within the scope of the appended claims. Similarly, that the mate- 1G0 rials and finishes of the several parts employed may be such as the manufacturer may decide .or varying conditions or uses may demand.

Having thus described our invention, what 105 we claim and desire to secure by Letters Patent is I 1. A bristle bar for brushes comprisin an elongated strip having a line of perforations extending lengthwise thereof and near one no marginal edge of the strip, said marginal edge being bent downwardly substantially at right angles to the portion of the strip within which the perforations occur, the body of the strip upon the opposite side of the perforations being bent substantially at rightangles to the portion carrying the perforations and being bent upon itself around a wire, the folded portions being pressed toward each other to hold the wire in position and to secure bristles upon the wire and which bristles extend through the perforations in the first mentioned edge of the posed at the crotch of the fold, the folded portions of the body then being pressed toward each other to substantially conform to the wire and to extend parallel with relation to each other and with the folded edge of the body portion substantially in line with the late whereby bristles extending around t e wire and through the perforations will be finally held in position.

3. A brush comprising a back formed with a plurality of longitudinally extending slots in one face thereof, the bottoms of said slots being enlarged with relation to the remainder of each slot and a plurality of bristle bars adapted to be moved'longitudinally of each slot and to be positioned therein, said bars comprising a plate having a longitudinally extending row of perforations adjacent one side thereof, a portion of the plate being folded down at opposite sides of the perforations to form a width of plate substantially equal to the width of'the elongated slots in the brush back, the edge of the plate adjacent the perforations being turned downwardly and resting against one wall of the slot within which it is seated, the opposite edge of said plate being bentvdownwardly to rest against the opposite wall of the slot within which it is seated and being bent upon itself around a wire to substantially conform to the contour of the slot and to be folded around a wire around which bristles are wrapped and which bristles extend through the perforations in the bar and means for simultaneously looking all of said bars within their respective slots in the brush back.
