Description

March 19, 1929. H. F. EBERT 1,706,058
BRUSH Original Filed July 15. 1926 Patented Mar. 19, 1929.
UNITED STATES PATENT OFFICE.
BRUSH.
Application filed July 15, 1926, Serial No. 122,668.
This invention relates to brushes and has special reference to the types of brushes wherein the bristles have their basal portions set into a ferrule and there held by a cement preferably of rubber.
One important object of the invention is to improve the general construction of brushes of this character.
A second important object of the invention is the provision of improved means for securing the bristles in the ferrule of such a brush. A third important object of the invention is to provide an improved locking element of novel construction for securing such bristles. I
lVith the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.
In the accompanying drawings like characters of reference indicate like parts in the several views, and:
Figure 1 is a side elevation of the improved brush removed from its handle.
Figure 2 is an axial section therethrough.
Figure 3 is an end view of the ferrule used herewith.
Figure 4 is an enlarged perspective view of the locking element.
In the brush here shown there is provided a ferrule 10 of cup shape and this ferrule has one end open and the other end provided with a closure 11 wherein is a polygonal opening 12 preferably triangular in form. Adjacent the open end there is proided an annular flange 13 and the ferrule is also preferably formed with a screw thread 14 so that it may be screwed into the socket of a suitable handle (not shown).
The bristles 15 are bunched in the usual manner and have their but-ts or basal ends positioned in the ferrule and there secured by a cement 16 of suitable rubber composition. The locking member is polygonal in cross section as at 17 to fit the opening 12, being accordingly preferably triangular in cross section. This member is slightly longer than the ferrule and terminates at one end in a pyramidal point 18 and at the Renewed December 1, 1928.
other end in a flat disk shaped head 19 which ears against the outside surface of the closed end of the ferrule. This member also has a series of spaced circumferential grooves 20. When this member is inserted the butts of the bristles are tightly compacted in the ferrule and the cement, entering the grooves 20, holds the locking member firmly in position so that it cannot accidently come loose. In fact the locking member is so securely held that it can only be withdrawn by destroying the brush and also the bristles cannot come loose on account of the manner in which this member compacts them in the ferrule.
There has thus been provided a simple and efficient device of the kind c escribed and for the purpose specified.
aving thus described the invention. what is claimed as new, is: i
1. A brush comprising a ferrule closed at one end and open at the other, a. bunch of bristles having their basal ends inserted in the ferrule and there secured by cement, and aheaded locking member extending through the closed end of the ferrule and compacting the basal ends of the bristles within said ferrule, said locking member being polygonal in cross section and having a pyramidal point projecting into the bristles beyond the ferrule.
2. A brush comprising a ferrule having one end closed and provided with a centrally disposed triangular opening, bristles having their basal ends positioned in the ferrule, a locl ing member of triangular cross section having a point at one end and a disk shaped head at the other, said member passing through the opening in the ferrule and the head resting against the closed end of the ferrule, said member being further provided with spaced circumferential groove:-:. and cementin said ferrule surrounding the bristles and member and entering said grooves. 7
3. A bristle locking element for brushes consisting of a polygonal body having a pyramidal point at one end and a disk shaped head at the other end, said body having spaced circumferential grooves.
In testimony whereof I atliX my signature.
HENRY F. EBERT.
