FLASHLIGHTS-BRACKET FOR BICYCLES.
Specification of Letters Patent.
Patented Oct. 11, 1921.
Application filed August 5, 1919. Serial No. 315,474.
To all whom it may concern Be it known that I, EWALD F. PAWSAT, a citizenof the United States residing at Sheboygan, county of Sheboygan, and State of lVisconsin, have invented new and use ful Improvements in Flashlight-Brackets for Bicycles, of which the following is a specification.
My invention relates to improvements in flash lightbr ackets for bicycles.
The object of my invention is to provide a form of clamp, adapted to engage the handle bar of a bicycle, and composed of members which can be quickly assembled about the handle bar, and securely clamped thereto by a single clamping bolt; also to provide means, connected with the handle bar clamp, for supporting the flash light at a suflicient distance from the handle bar, and by an arm having suflicient flexibility to absorb shocks and vibrations; to provide a form of construction in which the support will hold the flash light barrel at a substantial distance above the handle bar so that it will not strike the'handle bar, or the handle bar clamp, nor interfere with the adjustment of the clamp in attaching it or removing it from the handle bar; to provide a relatively flexible clamping member adapted to engage the flash light barrel, and which is securely fastened to the arm of the handle bar clamp; to provide means whereby the clamp which engages the flash light barrel may be adjusted to barrels of differing size with substantially continuous clamping pressure upon the barrel throughout a nearly complete cylindrical zone; and in general to provide a flash light bracket which can be made at minimum cost, and which will be adapted to the requirements of any ordinary handle bar, and any ordinary flash light barrel, adjustability, durability and convenience in assembly and removal being taken into consideration.
In the drawings Figure 1 is a side elevation showing a fragment of a bicycle steering head and handle bar, one arm of the handle bar being shown in cross section with my improved bracket secured thereto, and supporting a flash light.
Fig. 2 is a fragmentary view of the steering head, as seen from the rear side, the flash light barrel being illustrated in sec- .bolt 6.
shown at 9 in Fig.
tion on line 22 of Fig. 1, and a portion of the handle bar clamp being broken away.
Like parts are identified by the same reference characters throughout the several views.
A set of clamping members having arcuate portions 1 and 2 are adapted to. embrace the handle bar 3 of the bicycle, and are provided with depending ears 4 and 5, suitably apertured' to receive a clamping The member 2 is provided with a forwardly projecting arm 7, upwardly ofl set at an intermediate point 8. From the upper end of the offset 8 the arm projects forwardly, and is transversely curved to provlde a concave upper surface, as best 1. A band 10 ofthin flexible material, preferably resilient, has
its central portion secured by rivets or other fastenings 12 to the curved surface 9 of the outer extremity of the bracket arm 7, and the portions of the band on each side of this point of attachment are normally upwardly curved, substantially in the arc of a circle, but with the upper extremity ex tended in the form of clamping ears l3 and 141-, each having a series of apertures 15 and 16 respectively to receive a clamping bolt 17, adapted to be interchangeably used in any set of registering apertures 15 and 16, whereby a thumb nut 18 may be employed to clamp the ears together about the barrel 20 of the flash light. For small barreled flash lights the bolt 17 will be inserted through the lower set of apertures 15 and 16, and for the larger sized barrels it will be inserted through the upper or outer set, the band having suflicient flexibility to allow it to draw into conformity with the barrel of. the flash light in each case under the pressure of the clamping nut 18.
By making the apertures 16 oval in form in one of the ears, and contouring the shank of the clamping bolt 17 accordingly, the
bolt will be held against rotation when the clamping nut is being adjusted, and therefore the clamp may be drawn up at any time if it should become loose, without requiring the rider to dismount, one hand only being required to tighten the nut 18.
The clamping members 1 and 2 are preferably formed of considerably heavier material than the band 10 in order that these members may be bound upon the handle bar with absolute rigidity. The member 1 has its upper end portion provided with a lip 22, adapted to pass through a slot 23 in the arm 7. The upper end or extremity of the lip 22 is forwardly curved, whereby when the member 1 is clamped to the member 2 about the handle bar, this lip 22 will be securely interlocked with the arm 7, and cannot be disengaged therefrom without unscrewing the clamping nut 24-.
With the above described construction, it is obvious that the parts can be very quickly assembled in position for use, the member 2 being first applied to the handle bar, after which the lip 22 of the member 1 will be inserted through the slot 23, and the member 1 swung downwardly into contact with the front surface of the handle bar, after which the ears 4 and 5 may be clamped together by the bolt 6.
' The barrel of the flash light may then be inserted between the two halves of the flexible band 10, and clampingly engaged thereby by inserting the bolt 7 through the proper set of holes 15 and 16, and turning up the wing nut 18. ()wing to the fact that the middle portion of the arm 7 is upwardly oifset at 8, it is obvious that the members 1 and 2 may be adjusted to or removed from o the handle bars at any time, without removing the flash light from the clamping band 10. It will also be observed that the arm 7 supports the flash light barrel from a point in front of and above the handle bar, where- .by vibrations may be absorbed to a considerable degree, and no movement or vibration of the handle bar will cause the barrel to strike either the bar or any portion of the bracket in a manner to Produce rattling or hammering noises.
Owing to the fact that the handle bar clamp is independently adjustable, it is obvious that the barrel of the flash light may be either held in a horizontal position or tilted to any desired inclination for the purpose of lighting the road-way at the desired distance in front of the bicycle.
I claim In a flash light bracket, a handle bar clamping member provided with a forwardly extending arm, upwardly offset at an intermediate point, and provided with a transversely concave end portion, in combination with another handle bar clamping member, means for securing the barrel of a flash light to the concave portion of said arm, said barrel engaging means comprlsing a flexible band having upwardly extending end portions, each provided with a plurality of apertures adapted to receive a clampingbolt, said band being sufficiently flexible to be drawn into conformity with flash light barrels of differing size by the clamping bolt inserted through the appropriate set of apertures.
In testimony whereof I aflix my signature in the presence of two witnesses. V
