rooTrrBRUsHf I L? Y Application This invention has for object a toothbrush inwhich the handle and the brush proper are independent from each other. The brush, rendered removable, can thus, when its hair or bristles are worn out, be easily separated from the handle and replaced by a new brush.
The invention is essentially characterized by the particular method of assemblagey and clamping of the brush body, the handle. This assemblage, in which intervene only parts of simple construction, is very easily and rapidly effected. f
The invention is illustrated in the accompanying drawing giving, vby way ot example only, a typical form ot construction.
Fig. 1 is an elevation of the assembled' tooth-brush.
Fig. 2 is a longitudinal section thereof made according to line A-B of Fig. 1.
Fig. 3 is a side view ofthe brush head. Fig. 4 is a viewY of the handle. Fig, 5 is an end view of the handle, on the side which receives. the brush head.
In the iigures of the drawing is seen the` body of the brush head 1 with its hair or bristles 2; this body, which will have all suitable dimensions and the shape of which will generally be that shown in the drawing, is provided with a longitudinal channel 3 and has, et, 4 the bottoms of which are constituted by two fiat portions 5, 5. The handle 6, perforated with a channel 7 forming an extension o1 the channel of the brush 3 and which. widens at 8, near the rear part of the handle, receives at its end 6 one of the fiat 'portions 5 or 5 of the brush, which latter can be mounted on'one side or the other.
The assemblage is effected through two intermediate members. One of these members is provided with a head 9 taking a bearing against the flat part 5 or 5 and carrying al rod 10 which lits in the channels 3 and 7; the other member 1l constituting a pulling rod terminated by a milled knob 12 its inthe enlarged portion receives in an internally screw-threaded end portion 13, the screwthreaded end 14 of the bearing rod 10 Finally, the front end of the handle is provided with a rounded portion 6 capable of fitting about the contour of the brush body and on which projects the rectangular boss 6 which can tit on the flat portion 5 (or 5').
The @per-ation of assemblage of the brush,
removable fromV completely home.
at its opposite ends, two grooves 8 of the channel of led May V10, l1927,` Serial No; 190,272, andnFi-ance April 6, 1927.
the constituent elements of which have y been described will.v be'. easily understood.
The bearing rod 10 having 'been introduced inthe channel 3, it is engaged into the channel 7, so that the boss 6 comes into contact with the fiat portion 5 at the bottom of the groove .tor 4. Y
The pulling rod 11 is then slidy in the open portion 8 of the handle until its end encounters the screw-threaded part of therod 10. By then turning the rod 11 through the medium of its operating milled knob, this rod .is screwed on the preceding one until the head 9 exerts on they end of the brush body a suicient stress for causing this body to perfectly fitV against the handle and to be` rendered rigid with the latter.
The tooth-brush is taken to pieces withV vthe same facility by the reverse operation.
It will be seen that an important advantage of the 'above described tooth-brush, re-
sides 1n the fact that, on the same handle y can be fitted brushes of diierent lengths;` according to .the length of the brush to be mounted on the handle, the rod 10 enters more or less into the channel 7 and, consequently,` pensated This knob will therefore these differences of length are comwhen the milled knob 12 is screwed be screwed moreor less according as a small, l
middle size or large brush will be fitted on the handle. l
Various Vmodifications can be' provided; for instance, the inner screw-threadsmight be formed on 'the rod 10 and the outer screwthreads on the pulling rod'll, but this form' of construction which would necessitate giving to the channel 3 a great diameter, is less practical than the preceding one.
It is to be understood that this brush, body or handle, can be made of any desirable materials, metal, as for instance aluminium, or bone, moulded plastic materials, galalith, etc. and that it can receive any desirable shapes or decorations, the invention residing inthe principle ofassemblage and of clamping of the brush body proper on the handle by means of two intermediate vmembers screwing on eachother.
