Improvements in and connected with Brushes.
We JOSEPH BINGEMAN and OLIVER MARTIN, Manufacturers, of 928 F. Street
Washington, D.C., U.S.A. do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained, in and by the following statement :-
Our invention relates to improvements in that class of brushes in which doubled
tufts of bristles or fibre are secured in the holes or grooves of a block or head by
wire fasteners; and it has for its general object to provide such a brush comprising
a block or head having elongated holes or grooves in its face, and cheap and simple
wire fasteners adapted to be inserted and secured, one in each elongated hole or
groove, to secure long tufts of bristles or fibre therein and being also adapted to
engage the block or head in such a manner that tension or pull on the bristles or
fibre will tend to more securely fix them in position.
With the foregoing ends in view, the invention will be fully understood from
the following description and claims when taken in connection with the annexed
drawing, in which:
Fig. 1, is a longitudinal section of a brush embodying our invention, with one
fastener shown as engaging the head or block to secure a tuft of bristles thereto
and another fastener as simply inserted in one of the holes or grooves of the head
or block.
Fig. 2, is a plan view of the face of the block illustrating the various forms of
holes or grooves which may be formed therein.
Fig. 3, is an enlarged section illustrating one fastener in engagement with the
head or block and a portion of another fastener as simply inserted in one of the
holes or grooves thereof, and:
Fig. 4, is an enlarged elevation illustrating one of our fasteners ready to be
inserted in a hole or groove of a block.
Referring by letter to the drawings:-A, indicates the head or block of our
improved brush which is preferably formed of wood and is provided in its face
with elongated holes or grooves B, C, of any suitable form; D, indicates the
doubled tufts of bristles or fibre, and E, indicates our improved fasteners; one of
which is employed to secure each doubled tuft in the head or block. These
fasteners E, are respectively formed from a single piece of suitable wire and they
each comprise essentially the body portion E', the angular arms G, at the ends of
the body portion and the angular, outwardly-extending, pointed branches or
barbs H, at the ends of the arms G, which branches or barbs are about one half
as long as said arms G, and extend parallel or approximately parallel to the
body E', as shown.
The arms G, of the fasteners are bent inwardly at the time of manufacture as
shown in Fig. 4, and the said fasteners are thus interposed between the doubled
tufts of bristles or fibre and with the tufts may be readily pressed in the holes or
grooves B, C, of the head or block A, until the inner portions of the tufts bear
against the inner walls of the holes or grooves, as shown in Fig. 1.
The fasteners enter the holes or grooves in the head or block with the arms G,
in the position shown at the right of Fig. 3, that is to say with the arms G,
extending inwardly oblique from the body toward the face of the head or block
and with the points of the branches H, resting adjacent to the walls of the holes,
and when the tufts and fasteners have been sufficiently inserted, the arms G, are

page_text: forced outwardly by any suitable means so as to imbed the pointed branches or
barbs in the head or block as better shown at the left of Fig. 3, and secure the
fasteners and consequently the tufts of bristles in position in the holes or grooves
of the head or block. It will be readily perceived that when the fasteners are
thus secured in the head or block, any tension or pull upon the bristles or fibre
will tend to force the branches or barbs H, which extend at right angles to the
line of tension, into the head or block and more securely fix the fasteners in
position, and that consequently there is no liability of the fasteners or the bristles
or fibre pulling out in use, which is a desideratum."
It will be seen from the foregoing that inasmuch as our improved fastener may
be manufactured very cheaply and may be quickly and easily fixed in the head or
block, to secure the bristles or fibre therein, we are enabled to produce a strong
and durable brush at a small cost; and by reason of the arms G, of the fasteners
being provided with the angular branches or barbs H, it will be seen that a single
long fastener may be employed to secure a long tuft of bristles in an elongated
hole or groove of the block or head as the branches or barbs H, are not liable to
be drawn out of the walls of the hole or groove by the bowing of the body
portion E, incident to pull or tension on the bristles.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The herein described brush consisting essentially of the head or block having
an elongated hole or groove in its face, a doubled tuft of bristles or fibre inserted
in said hole or groove, and the fastener formed from a piece of wire and having
the comparatively long body portions E', the angular arms G, at the ends of the
body portion, and the angular, outwardly-extending branches or barbs H, at the
ends of the arms G, extending parallel or approximately parallel to the body
portion; the said fastener being interposed between the portions of the tuft within
the hole or groove of the block with the arms G, outward and the barbs or
branches H, extending into the walls of the hole or groove in a direction at right
angles or approximately so to the length of the bristles or fibre, substantially as
and for the purpose set forth.
2. As an improved article of manufacture, the herein described tuft fastener
formed from a piece of wire and comprising the comparatively long body portion E',
the angular arms G, at the ends of the body portion and the angular, outwardly-
extending, pointed branches H, at the ends of the arms G, resting in positions
parallel or approximately parallel to the body portion E', substantially as and for
the purpose set forth.
