BRUSH CONSTRUCTION.
Application led April 276, 1927. Serial No. 186,708.
The invention has for an Object to leffect improvements in metal brushheads.` It is an important aim of the invention to provide a novel form of brush head or tuftmounting plate and to coordinate the head with the casing by an improved fastening adapted to be incorporated in brushes of standard shape and size with a minimum of complication in production and use.
It is an especially important purpose of the invention to enable the provision of a tuft-socket of novel form and by a novel method, by which the efficiency of the head in retaining tufts is materially enhanced, so that a maximum length of service may be obtained and use of a minimum amount of metal involved.
Additional objects, advantages and` features of invention will be understood from the construction, arrangement and combination of parts hereinafter described and shown in the accompanying drawings, wherein Figure 1 is a side view of the complete brush,
Figure 2 is a cross section thereof,
Figure 3 is aback view of the case,
Figure 4 is a similar view of the head.
There is illustrated a brush case 10, which may conform to usual practices in brush construction, and is especially adapted to be made in some of the more attractive hard woods. The brush head comprises an ovate plate 11 with a multiplicity of tutt-sockets 12 formed therein, as will be described. The case 10 is recessed as at'13 to receive the head plate snugly, although it is believed preferable to have the edges of the recess bevelled at the end of the case farthest from the handle in the form of brush shown, to facilitate its ready removal and replacement, as will be described. The plate 11 is bulged as customary in approved practice. In the present instance, the plate has a contour in plan corresponding to that of an egg, that is--the outer end is somewhat oblate or blunt as compared to the inner end. In the central body of the brush there is formed al pearsha-ped fslot 14 having its narrower portion toward the broader or oblate end of the plate. The bulging of the brush head permits the thickening of thecase centrally of the recess 13, as shown, and an aperture 15 is formed through the central body of the case in line with the narrow part of the slot of the head when the latter is in place in the case. The outer or back face of the case f 1s formed with a` circular recess'around the aperture 15. Slidable in the aperture there is a Vpin 17, the large, flaty head of which fits loosely in the recess 16, the stem being in-k serted so as to project through the inner face of the case. The pin is formed with a groove 18 therearound adjacent its inner extremity, the groove being adapted to receive edge portions of the plate 10, as will appear. The larger part of the slot 14 is adapted to receive the pin freely therethrough, but the narrow part of the slot is adapted to engage in the groove of the pin. When the head of the pin is pressed into the recess 16 the pin may pass through the slot 14 of the head plate 11, when this is introduced in po` sitionoverthe recessed side of the case. A light spring 19 is confined bet-Ween the head of the pin and the case. For convenience in retaining the pin against casual removal from the case the material at the inner side of the groove 18 is peened or cut so as to turn it outwardly, whereby it will engage the case around the aperture 15, to prevent withdrawal of the pin. It may be appreciated that the spring 19 need not bear the pin outward so as to press this outturned or peened part of the pin against the case with great force, if at all.
In order to engage the head-plate 11 in the case, the handle of the brush is grasped with the second, third and the fourth digits and the thumb of one hand, while the forefinger of the same hand is pressed upon the head of the pin 17. With theother hand the plate 11 is then positioned to receive the pin through the larger part of the slot 14 and the head then moved longitudinally upon the case to engage the narrower part of the slot in the groove 18, after which release of the pin will draw the plate snugly into the recess 13 of the case. Removal of the plate 11 is accomplished by a reversal terengaging elements on the brush head and pin inoperative when the pin head is depressed.
2. The structure of claimV l in which the said recess of the case is hevelled at one side so that said side slopes outwardly, whereby to facilitate starting` of the head from the case by longitudinal manual pressure thereon coincident With depression ot said pin.
3. A brush comprising a case having a recess to receive a head, a head adapted to he set in the recess having a longitudinal central key slot, a manually operable pin slidably mounted centrally of the case at right angles to the plane of the case and having an inner end insertahle through the larger part of the key slot adapted to engage over the smaller part by relative movement of the head, and resilient means engaged With the pin to hold it yieldingly in retaining engageinent with the headg-said pin having an outer end exposed on the back of the case for depression hy the finger of an operator.
In Jtestimony whereof I aiix my signature.
