COMPLETE SPECIFICATION.
An Improved Lamp Bracket for Bicycles and other Vehicles.
I, FRANK THEODORE WILLIAMS, of Meriden, County of New Haven, State
of Connecticut, U.S.A. Machinist, 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 :-
My invention relates to improvements in lamp brackets and consists, in the
construction and arrangement of the parts thereof hereinafter fully described.
The object of my invention is, to provide a means whereby a lamp may be held
in firm engagement with the frame of a bicycle or other vehicle, the said bracket
being provided with clamping members and supplemental parts therefor whereby
the said clamping members have, the universal capacity of being adapted to
variously formed parts of the frame.
My invention is illustrated by the accompanying drawing.in which
Figure 1 is a side elevation of my device in one of its operative positions.
Fig. 2 is a plan view of my invention as it appears in another position and
provided with supplemental clamping parts.
Fig. 3 is a section of a detail of the mechanism on x-x Fig. 1.
Fig. 4 is a section of Fig. 2 on a plane corresponding to the line x-x Fig. 1,
illustrating the end of one of the clamping members, only.
Fig. 5 is a perspective view of a detail.
Similar letters refer to similar parts.
A is a lamp. B is a lateral projection from the side of the lamp affording a
means for connecting the same to an intermediate supporting arm D. The faces
of the parts B and D are by preference knurled or roughened, as shown, so that
by means of a bolt E and nut E' the said parts B D may be held in a firm engage-
ment with one another as shown clearly in Fig. 2. The intermediate arm D is by
preference also pivotally connected to the clamping members F F by means of the
bolt G. G is a nut operating on said bolt G to afford a means for, setting the
parts in the desired lateral plane, the bolt G being by preference arranged in a
substantially vertical plane, while the bolt E is arranged in a substantially horizontal
plane, so that, assuming the clamping arms F F are secured in a desired position the
lamp may he arranged at a suitable angle thereto to cause its rays of light to be
directed in the path of travel of the vehicle. Suitable means are provided to
draw the arms F F into engagement with a portion of the framework of the
vehicle, the means illustrated being a bolt H and set-nut H¹. The clamping
members F may he shaped so as to be attached to a portion of the frame of any
desired shape, for instance, such as illustrated in Fig 1, in which I represents the
tubular head of a bicycle.
To provide a means whereby the clamping members of the bracket may be
attached to bodies of other shape than shown in Fig. 1, such as for instance
shown in Fig. 2, in which J represents a front fork-blade of a bicycle, I provide
supplemental detachable clamping arms K K, which may be readily attached to
the free ends of the main clamping members F F. L L are jaws of somewhat
angular formation toward the outer extremities of the supplemental clamps K.
M is a perforation formed in each of the clamps K at a point intermediate in
their length. N is a perforation toward the free extremity of each of the
main clamping members F. The clamping members F are provided at their

page_text: free extremities with extensions OO. P P are overhanging shoulders or
hooks, said hooks being raised slightly out of the plane of the extensions OO,
as shown.
In attaching the supplemental clamps K K to the main members F F, the
extremities of the members K opposite the jaws, Lare inserted through the
perforations N in the clamps F, see Figs. 2 and 4. The hooks P are passed.
through the perforations M in the clamps K, each of said clamps being then
pushed rearwardly into the position shown in Figs. 2 and 4, in which the inner
extremities of the clamps K project into the space between the clamping
members F and the hooks P overhang and engage the outer surface of the
clamping members K. The perforations M in the last named clamping members
are sufficiently large to permit the bolt H to be passed through as shown in Fig. 2,
the presence of said bolt preventing the supplemental clamps K from becoming
accidentally disengaged from the main clamps F.
As shown, the main clamping members F are particularly adapted to engage
rounded surfaces, whereas the jaws of the detachable clamps K, are particularly
adapted to engage somewhat angular bodies, although manifestly I may give
such conformity to either or both of said clamping members as may be
desirable.
'
Suitable pads may be provided on the inner engaging surfaces of the jaws to
prevent marring the finish of the frame of the vehicle.
The capability of detachment of the supplemental arms from the main clamping
arms is a most useful feature where it is desired only to attach the bracket to a
portion of the frame such as the front frame tube or head of the bicycle, in which
only the main clamping members may be utilized, thus lightening the structure and
removing an unsightly and then useless attachment upon which the clothing of the
rider may become entangled or torn.
In carrying out my invention some changes may be desirable and I therefore do
not limit myself to the specific form and arrangement shown, but hold myself at
liberty to make such alterations as are fairly within the spirit and scope of my
invention.
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. In a lamp bracket for bicycles and other vehicles, main clamping arms,
supplemental clamping arms detachably connected to the free extremities of the
main clamping arms and operating at the exterior thereof.
2. In a lamp bracket for bicycles and other vehicles, main clamping arms,
supplemental clamping arms detachably connected to the free extremities of the
main clamping arms.
3. In a lamp bracket for bicycles and other vehicles, main clamping arms
hinged or pivoted together, supplemental clamps detachably connected to the
free extremities of the main clamping members and operating at the exterior
thereof.
4. In a lamp bracket for bicycles and other vehicles, main clamping arms recessed
to engage substantially rounded bodies and hinged or pivoted together, supplemental
clamps having at their free extremities jaws for engaging substantially angular
bodies and detachably connected to the free extremities of the main clamping
members and operating at the exterior thereof.
5. In a lamp bracket for bicycles and other vehicles, main clamping_arms
hinged or pivoted together, said clamping arms being perforated at N and
carrying hooks P, supplemental clamps having perforations intermediate in their
length and adapted to be detachably connected to the free extremities of the main
clamping members and operating at the exterior thereof.
6. In a lamp bracket for bicycles and other vehicles, main clamping_arms
hinged or pivoted together at one end, said clamps having perforations N and

page_text: carrying hooks P rearward of said perforations, supplemental clamping arms having
perforations intermediate in their length detachably connected to the free extremities
of the main clamping members and operating at the exterior of said main clamping
members, an adjusting bolt at the free ends of said clamping members and passing
through said supplemental clamps when the latter are in engagement with said.
clamping members, substantially as described.
