An Improved Lamp Bracket for Bicycles and other Vehicles.
I, WILLIAM CLIFFORD HOMAN, 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 or supports particularly
useful for the purpose of connecting a lamp to a bicycle or other vehicle.
The object of my invention is to provide a simple and effective means for
accomplishing the desired end, which means may be easily and quickly attached to
the frame of a vehicle at a suitable point, and by means of which the position of
the lamp may be readily adjusted to any desired angle.
My invention is illustrated by the accompanying drawing, in which
Fig. 1 is a plan view of the forward portion of a bicycle, showing the lamp and
bracket support in one of the operative positions.
Fig. 2 is a relatively enlarged longitudinal sectional view through the centre of
the bracket.
Fig. 3 is a plan view of said bracket, partially dismembered and showing the
clamping members thereof in a reversed position.
Fig. 4 is a side elevation of the part shown in Fig. 3, the position of the clamping
members being the same as shown in Figs. 1 and 2.
Similar letters refer to similar parts throughout the several figures.
A is the front frame tube of a bicycle, commonly termed the head. B Bare the
front fork blades of a bicycle. D is a lamp. E is a connecting piece, preferably
ring-shaped, suitably fastened to the body of the lamp. The opposite surfaces of
the ring E are by preference knurled or roughened. F is a tubular supporting
arm, and F is an annular shoulder secured to or formed as part of the said arm F
and located toward one end thereof. The outer face of this shoulder F is also by
preference knurled or roughened. G is a bolt passing transversely through said
arm F near the end opposite the shoulder F. G¹is a set nut on said bolt G. His
a shank, one end of which loosely surrounds that portion of the bolt G within the
tubular arm F. The opposite end of the shank H is threaded as shown, and
projects through and beyond said tubular arm F. H' is a set out on the threaded
extremity of the shank H. I is a suitably formed washer, loosely surrounding the
threaded end of the shank H, and adapted to bear against the outer face of the
connecting ring E when the parts are in the operative position. The set nut H¹
bears against the other face of the said washer I, so that by this means, the ring E
may be tightly pressed against the shoulder F. J J are clamps arranged on
opposite sides of the inner end of the supporting arm F, as shown. The bolt G
passes through said clamps, as shown, so that by means of the nut G³, the said
clamps may be tightened or loosened at will. These clamps J, are by preference
shaped so that one end of said clamps will engage the cylindrical front frame tube A
of the bicycle when said clamps are turned into the positions shown in Figs. 1, 2
and 4, the opposite ends of the clamps being shaped to engage one of the forked
tubes B when the position of said clamps is reversed, as shown in Fig. 3. To more
securely prevent the clamps J J from twisting or slipping out of line with the
arm F, I provide recesses K K substantially midway in the ends of said clamps, so
that when in the operative position the inner ends of the clamps will embrace said
arm F to an extent sufficient to prevent twisting.
The operation of the device is as follows. The clamps J J are loosened by

page_text: unscrewing the nut G¹. The corresponding extremities of said clamps J are passed
around that portion of the vehicle frame to which it is desired to attach the
bracket. The set nut G¹ is then turned, drawing said clamps into secure engage-
ment with said frame. The connecting ring E is then passed over the opposite
free end of the shank H and supporting aim F until it abuts against the shoulder F',
the washer I is then placed over the end of the shank H until its inner edge or
surface abuts against the ring E. The set nut H¹ is then screwed on to the shank
forcing said ring into tight contact with the shoulder F; and at the same time
drawing the shank H outwardly, thus drawing the bolt G laterally into tight
contact with the adjacent edges of the tubular arm F, through which said bolt G
passes. By this means all of the parts are securely held together preventing
rattling that might otherwise occur by the vibration of the vehicle. The lateral
adjustment of the lamp is afforded by shifting the position of the bracket around
the frame tube, while the vertical position of the lamp may be shifted by loosening
the nut H¹, which permits the said lamp to be raised or lowered.
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 vehicles, a supporting arm, a transverse bearing
shoulder near its outer end, a projection on the lamp for detachably securing the
lamp on said arm, and a clamp operating in line with and on said arm, and clamping
said projection against said shoulder.
2. In a lamp bracket for vehicles, a supporting arm a transverse bearing
shoulder near its outer end, an adjustable clamp near its inner end, a projection on
the lamp for detachably securing the lamp on said arm, and a clamp operating in
line with and on said arm, and clamping said projection against said shoulder.
3. In a lantern holder, an arm, a clamp near one end thereof, a transverse piece
engaging said clamp, a lamp supporting member adjustable on said arm, and a
clamp for said member, one part of which clamp engages said transverse piece.
:
4. A lamp bracket for cycles, comprising, a supporting arm, a shoulder near its
outer end, adjusting clamps near its inner end, a bolt for operating said clamps,
a shank, one end of which engages said bolt while the opposite end projects beyond
said supporting arm, and means for detachably securing the lamp to the outer end
of said arm.
5. A lamp bracket for cycles, comprising, a tubular-supporting arm, a shoulder
near its outer end, adjusting 'clamps near its inner end, a clamp operating bolt, a
shank within said arm engaging one end of said clamp operating bolt the opposite
end projecting through said supporting arm, and means for detachably and
adjustably securing said lamp to the outer end of said arm.
6. A lamp bracket for cycles, comprising a tubular supporting arm, an annular
shoulder near its. outer end, adjusting clamps towards its inner end, a clamp
engaging bolt, a shank within said tubular arm one end of said shank engaging
said clamp operating bolt, the opposite end projecting through and beyond said
supporting arm, a connecting piece carried by the body of the lamp and bearing
against said shoulder when the parts are assembled, substantially as described.
7. A lamp bracket for cycles comprising, a tubular supporting arm, an annular
shoulder near its outer end, reversible clamps pivotally mounted upon a bolt G
near its inner end, the inner ends of said clamps bearing against said supporting
arm, a shank within said tubular supporting arm, one end of which engages the
bolt G, the opposite end being screw-threaded, a connecting piece E substantially
ring-shaped and carried by the body of the lamp B, and a set nut H¹ operating
upon said shank H.
8. In a lamp bracket for bicycles and other vehicles, a lamp supporting arm,
provided at its inner end with reversible clamps, loosely mounted at a point
intermediate in their length upon a bolt transversely placed with respect to said
supporting arm.

page_text: 9. In a lamp bracket for bicycles and other vehicles, a lamp supporting arm
provided at its inner end with reversible clamp, pivotally mounted at a point
intermediate in their length, said clamps having on one side of said pivotal support
substantially semi-circular recesses adapted to receive a cylindrical frame tube, and
on the other side of said pivotal support with substantially V-shaped recesses
adapted to engage a flattened frame tube such as a bicycle fork.
10. In a lamp bracket for bicycles and other vehicles, reversible clamps pivotally
mounted at a point intermediate in their length, one end of each of said clamps
being bent into substantially semi-circular form to engage with a cylindrical frame
tube, the opposite ends being provided with substantially V-shaped recesses to
engage a flattened frame tube and recesses K K in the ends of said clamps,
substantially as described.
