Improvements in and relating to Lamp Brackets for Cycles.
I, EDWARD LAMBRICK WILLIAMS, of Kenosha, in the County of Kenosha, and State
of Wisconsin, United States of America, Manufacturer, 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 :-
This invention relates to lamp brackets, and has for its object to provide a simple
and efficient lamp bracket for bicycles and the like, which is adapted to be secured
to the handle bar stem, and which may be readily and firmly secured in position and
adjusted upon the support and as readily removed, being simple in construction,
of light weight and compact. To these ends my invention consists in certain novel
features which I will now proceed to describe.
In the accompanying drawing,
Figure 1 represents a side elevation of the front portion of a bicycle having my
improved lamp bracket applied thereto and carrying a lamp;
Figure 2 is a side elevation of the bracket; detached, a portion thereof being
broken away to illustrate the construction;
Figure 3 is a front elevation of the bracket;
Figure 4 is a detail view of the portion of the lamp whereby it is adapted to be
connected to the bracket;
Figure 5 is a detail sectional plan, taken through the handle bar stem above the
bracket, illustrating the connection between the bracket and stem; and
Figure 6 is a detail sectional view, taken on the line 6-6 of Figure 3.
My improved bracket may be constructed of any suitable material and shaped or
fashioned in any suitable manner. I prefer, however, to construct the same of sheet
steel, or similar material, striking the same up into the desired form by means of
suitable dies. The bracket proper consists of a body portion or arm 10, which is
preferably U-shaped in cross section, as shown in detail in Figure 6 of the drawings,
and which is provided at its forward end with suitable means whereby it is adapted
to be connected to the lamp. In the present instance, I have shown for this purpose
a radially grooved disc 11 on the bracket provided with a central circular or annular
boss 12, surrounding a threaded aperture 13, which is adapted to receive a clamping
screw 14, by means of which a corresponding radially grooved disc 15 on the lamp,
having a central aperture 16 to receive the boss 12, may be clamped and held against
the disc 11.
At its rear end, the body 10 is provided with a clamp, whereby it may be secured
to the handle bar stem 17 of the bicycle. This clamp consists of a member 18 which
is secured to and preferably formed integral with the body 10, said member being
U-shaped in cross section, as indicated in Figure 5, the curved portion thereof being
adapted to fit upon the handle bar stem, while the terminal portions 19.
thereof, which are tangent or substantially tangent to the handle bar stein,
terminate in reversely hooked or bent flanges 20. The other member of the clamp,

page_text: which is indicated as a whole by the reference numeral 21, comprises a part 22 which
has grooved edges 23 to receive the flanges 20 of the member 18, a part 24 forming
a shoe adapted to bear against the handle bar stem 17 at the rear thereof and curved
or bent, as shown in Figure 5, to partly embrace said stem and thereby be held
firmly on the saine and prevented from rotating, and an adjusting or clamping
screw 25 which passes through a threaded aperture in the part 22 and bears against
or is swivelled in the part 24.
The body 10 is provided with an aperture 26 through which the brake rod 27 may
pass, and for the purpose of providing a suitable bearing for the rod in case it should
come in contact with the body of the bracket, the aperture 26 is provided with a
downwardly turned curved flange or bead 28, which presents a smooth surface for
contact with the brake rod.
The bracket thus described may be readily and quickly applied to the handle bar
stem of a bicycle. The member 21 being separated or detached from the member
18 of the clamp, this latter is placed in position against the stem and the member 21,
after having being prepared for connection with the member 18 by rotating the
screw 25 so as to draw the part 24 a sufficient distance towards the part 22, is con-
nected with the member 18 by engaging its grooved edges 23 with the hooked
flanges 20 of said member. This is accomplished by sliding the one part vertically
downward along the other, or by moving the two parts longitudinally relatively to
each other. The clanp having then been moved to the desired position upon the
stem, the screw 25 is turned so as to cause the part 24 to bear against the rear of
the stem, whereupon the part 22 will be forced rearward by the further rotation of the
screw and will firmly engage and interlock with the part 18, while the stem is held
firmly clamped between the semi-circular or curved portion of the member 18 and the
part 24 of the member 21. The bracket may be detached in an obvious manner by
loosing the screw 25 and sliding the two members of the clamp, or either of them, so
as to disengage said members.
The lamp 29 may be connected to the forward end of the bracket either by the
connecting device shown and described or by any other suitable connection.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A lamp bracket for bicycles having a clamp whereby it may be connected to the
handle bar stem or other like part, said clamp comprising two members having inter-
locking edges longitudinally movable relatively to each other for engagement and
disengagement, one of said members being provided with a clamping screw threaded
therein and having a shoe adapted to bear against the stem, substantially as des-
cribed.
2. In a lamp bracket for bicycles, the combination with a suitable arm or body, of
a clamp adapted to connect said bracket to the handle bar stem or the like and
comprising a U-shaped or semicircular member having hooked terminal flanges, and
a co-operating member composed of two parts, one provided with grooved edges to
receive the flanges of the first member, and the second adapted to bear against the
stem, and a set screw threaded through said first part and bearing against said second
part, substantially as described.
3. In a lamp bracket for bicycles, the combination with a suitable arm or body, of a
clamp adapted to connect said bracket to the handle bar stem or the like part and
comprising a U-shaped or semicircular member having hooked terminal flanges, and
a co-operating member composed of two parts, the one external and having grooved
edges to receive the flanges of the first member, and the second being internal and
curved or bent to fit the stem, and a set screw threaded through the first part and
having a swivelled connection with the second part, substantially as described.
4. A lamp bracket for bicycles having a clamp whereby it may be connected to the
handle bar stem or other like part, said clamp comprising two members having

page_text: interlocking edges longitudinally movable relatively to each other for engagement
and disengagement, one of said members being provided with a clamping screw
threaded therein and having a bearing against the stem, substantially as described.
