Improvements in Lamp Brackets.
I, WILLIAM CLIFFORD HOMAN a resident of Meriden, County of New Haven,
State of Connecticut, United States of America, Inventor, 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 improvements in lamp brackets and consists in the
novel construction and arrangement of the parts thereof, hereinafter fully
described.
The object of this invention is to provide a simple and inexpensive means of neat
appearance for securing a lamp or lantern in a suitable position upon the frame of
a bicycle or other vehicle, which means may be quickly and easily attached to the
frame of said vehicle at various points, as desired.
The invention is illustrated by the accompanying drawings in which→
Fig. 1 is a plan view, the bracket portion being somewhat in perspective.
Fig. 2 is a horizontal section of Fig. 1, the lamp portion being removed.
Fig. 2 is a similar view illustrating some of the parts in a different position from
that shown in the preceding figures.
Referring to the drawings, A is a lamp. B is a rearward extension from said
lamp by which the lamp may be secured to the clamping members of the bracket
desired manner.
proper in any
DD are main clamping members suitably
connected at one end, and adapted at their free extremities, as shown in
Figs. 1 & 2, to embrace a substantially cylindrical body, such as for instance, the
front fork tube, or head, of a bicycle. Any suitable means may be provided for
operating said clamping members to cause them to firmly engage the desired
portion of the vehicle frame, the means illustrated being an internally threaded
nut E carried by one of the main clamping members D, and a screw F carried by
the other member and co-operating with said nut E in the usual manner.
In practice it is sometimes desirable to attach the bracket to a somewhat angular
shaped portion of the frame, such as the front fork blade of a bicycle, and there-
fore a means is provided whereby the shape of the clamping faces may be modified
to accord therewith. To accomplish this end, wings G G are provided. These
wings are by preference pivotally supported within the main clamping members DD,
and, when in the inoperative position, the said wings are sheathed, preferably within
corrugations formed in said main clamping members as shown in Figs. 1 & 2. These
wings are so connected to the main clamping members that when swung from the
position shown in Fig. 2 to the position shown in Fig. 3, the free extremities of
said wings will form toward the inner free extremities of said main clamping
members, recesses of somewhat angular form particularly adapted to embrace some-
what angular bodies, such as the front fork blade H of a bicycle frame.
In operation, should it be desirable to attach the lamp to the fork blade of a
bicycle, the wings, or supplemental arms, appear in the position shown in Fig. 3.
To adapt the clamping members to embrace the head of a bicycle, the screw F is
disengaged from the nut E and the clamping members D moved apart sufficient to
permit the wings or supplemental members to be reversed to the position shown in
Fig. 2. The clamping means for drawing together the clamping members in Fig. 3
are shown to be in a forward position, slots in the sides of the main clamping
members D D permitting the same to be shifted forwardly, thus permitting the
screw to exert its power at a point close to the bearing support.

page_text: In Fig. 2 the nut E and the screw F are shown to be in suitable position to
permit the clamping members to embrace the substantially cylindrical body
referred to.
When the parts are in the position indicated in Fig. 2, the adjacent edges of the
wings G G by preference rest against each other, as shown, thus preventing
looseness or rattling of the parts, although manifestly other means may be provided
to accomplish this end.
In carrying cut my invention, some changes in the construction shown and
described may be desirable, and therefore the invention is not limited to the
specific construction shown and described, but includes such variations and
changes therein as will produce substantially the same result in substantially the
same way.
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 the lamp bracket, for the purpose described, main clamping members'
having substantially curved depressions toward their free ends adapted to engage
correspondingly shaped portions of a vehicle frame, wings carried by and between
said main clamping arms, said wings being capable of being turned to cause their
ends to project into the field of said curved depressions.
2. In a lamp bracket, for the purpose described, main clamping members,
depressions toward the outer end of said clamping members adapted to engage
rounded bodies, wings pivoted intermediate in the length of said main clamping
members, substantially as described.
3. In a lamp bracket, for the purpose described, main clamping arms having
depressions at their outer or free ends, wings pivotally connected to and between
said main clamping arms at a point intermediate in their length, corrugations in
said main clamping arms to sheath said wings when the latter are in, their
inoperative position, substantially as described.
4. In a lamp bracket, for the purpose described, main clamping arms,
supplemental arms or wings pivoted to and between said main clamping arms,
and means for drawing said clamping members toward each other, substantially
as described.
5. In a lamp bracket, two main clamping arms, each carrying a supplemental
arm or wing, corrugations in said main arms in which said wings rest when in the
inoperative position, a clamping means for said arms and a pivoted extension to
which the lamp or lantern is adjustably secured.
