COMPLETE SPECIFICATION.
Improved Bicycle Lamp Bracket Clamp
1, WILLIAM NICHOLS BEARDSLEY, Bookkeeper, of 268, Stratford Avenue,
Budgeport, in the County of Fanfeld, and State of Connecticut, United States of
America, do hereby declare the name 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 an improvement in lamp bracket clamps for bicycles,
and it consists in such a construction and combination of devices hereinafter more
fully set forth in the following Specification, and such features as I believe to be
new and novel particularly pointed out in the claims to follow.
To enable others to understand my invention reference is had to the accompanying
diawings and to the letters and figures of reference marked thereon which, together
with the Specification, clearly explain my device.
Fig 1 represents a view in perspective of my improved clamp whose sides are
pivoted so as to embrace various sizes of bicycle head, said sides having ears
integral therewith for supporting the lamp bracket, and
Fig 2 is an open upper plan view of the clamp and bioken section of the
bracket though lime a of Fig 1:
Fig 3 is a detail fiont side elevation of one of the side clamps,
Fig 4 is a detail upper plan view of the back piece of the clamp,
Fig 5 is an upper plan view of a modified construction of a spring clamp
wherein the back, sides and bracket eais are constructed of a single piece of
metal,
Fig 6 is a perspective view of a clamp embodying the same general features as
shown in the other views, but intended more particularly to be applied to one of
the forks of a bicycle so as to locate the lamp nearer the ground:
Fig. 7 is a vertical elevation of the device shown at Fig. 6, showing the side
clamps in open position.
Its construction and operation are as follows 1, 1° Figs. 1, 2 & 3 are the
swinging side clamps, each of which are provided with two ears integial with the
said sides and located at the top and bottom edges thereof and projecting at night
angles therefiom. Holes 3 (see also Fig. 5) are provided in said ears for the fiee
ends of the wire bracket 4, Figs 1 and 2. The back plate 5, Fig. 4, has its fice
ends formed in the eyes 6, through which also pass the said fice ends of the wie
blacket This forms a hinge for the sides 1, 1° of the clamp
As the material of which the clamp is composed is thin sheet metal the fiee
ends of the side clamps are each re-enforced by the bosses 7. attached thereto, one
of which canes the clamping screw 8, and the other is provided with a thicaded
hole therefor.
This feature of the pivotal side clamps enables them to be readily opened (see
Fig 2,) sufficient to embrace various sizes of heads without altering their form by
stiaming, as would be the ease with the construction shown at Fig 5. The
advantage to be gained in this latter construction lies in the cais 2 being, like the
swinging clamps, before mentioned, integral with the clamp and forming a cheap
and efficient means for attaching the wire lamp bracket thereto, but, of course,
this single clamp is more cucumscribed in its movements than the pivoted
clamps are
A further modification of the pivoted clamp is shown at Figs. 6 and 7, which
constinction, as before mentioned, is especially intended to embrace one of the

page_text: forks of the bicycle frame so as to bring the lamp nearer the ground The sile
clamps 1 1° in this construction are also made of sheet metal having the eyes be
formed in their ends enclosing the pivotal or hinge pin 9 The clamp 1 has the
long projecting ears 2 integral therewith to escape contact with the spokes of the
wheel, holes 3 being provided therein to receive the free ends of the wire-clamp
bracket The free ends of those side clamps are also provided with the eyes de
respectively. The former encloses the pin 10, which pivotally secures the head
portion of the clamping screw 1 The latter pivotally supports the extension
piece 12 on its pin 13. This extension piece is also made from sheet metal and
provided at its free ends with the eyes o. This extension carries, securely
attached thereto, the plate 14, having the locking head 15, bent at night angle.
thereto, which lead is provided with the hole 16, therethrough and the contracted
mouth or opening 17, for the purpose presently to be explained. The nut 18, 15
mounted upon the threaded portion of the sciew 11, and its reduced portion
provided with the circumferential groove 19. When, therefore, the clamp encucles
the fork of the bicycle the screw and head are brought together the
the head 15 will readily adunt said sorew, the nut is then run up until the flange
opemug
portion 20 thereof is brought in contact with the outer surface of such head, and
the clamp finly fastened to the said fork. The said head resting in the groove 19
cannot be withdrawn by any jar, owing to the contracted month 17 being unable
to pass over the enlarged portion of the nut, as reprosented by such groove.
17 of
Larger sizes of forks are provided for by the means of the extension piece 12
which can be secured by simply withdrawing the pin 13 and placing the eye in
the position now ocempied by the eye t. This will bring the head 15 faither to
the light of the present position.
While one of the constructions shown is particularly adapted for the head of the
bicycle and the other for the fork they all embody the same essential features, viz
the clamps are made of sheet metal with eyes formed therein for the hinge of
pivotal part, and the ears for the bracket wire integral therewith.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what 1
claim 18-
1. The herein described lamp-bracket clanıp made of sheet metal with ears on
the upper and lower edges thereof integral with said clamp, said eais nilanged
to support the lamp bracket and means for securing said clamp in place, as set
forth
2. The herein described lamp-bracket for bicyoles, compusing in combination
sheet metal side clamps, projecting ears integral therewith, for supporting the lamp
bracket, and also provide a pivotal point or hinge for said clamps, means whereby
said clamps are secured in position as set forth.
3 The herein described improvement in lamp brackets for bicycles, comprising
in combination, sheet metal side clamps, lamp-bracket cais integial with said side
clamps and projecting therefrom, the lamp bracket wires passing through said
eais to form both a support for said bracket and a binge for the side clamps, a
back piece having eyes in its ends to encircle sand bracket wies, sail back piece
closing the space between the pivotal points of the side clamps, a binding screw to
fasten the free ends of said clamps, as described and set forth.
4. The heien described improvement in bicycle lamp-bracket-clamps, comprising
in combination sheet metal clainps, bracket eais utegial therewith, pivotal supports
for said clamps and means for securing then fice ends, as described and for the
purpose set forth.
