BICYCLE-LAMP BRACKET.

SPECIFICATION formingpart of Letters Patent No. 623,453, dated April 18, 1899.

Application filed March 25,1898. $eTiR1N0- 75. 3% (NO mod To aZZ whom it may concern:

Be it known that I, CHARLES E.WHITMARSH, of the city of New York, borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and Improved Bicycle- Lamp Bracket, of which the following is a full, clear, and exact description.

My invention relates to an improvement in bicycle-lamp brackets, having for its object the formation of a swinging support for the lamp, which will enable the lamp to swing into any position necessary and thus to remain at all times in an upright position.

My invention consists of the novel features of construction which will be hereinafter described and claimed.

Reference is to he had to the accompanying drawin gs, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a bicyclehead, showing the bracket attached thereto and a portion of a lamp. Fig. 2 is a vertical section through the bracket. Fig. 3 is a front view of the same, and Fig. 4 is a top plan view.

-With ordinary fixed brackets for bicyclelamps it often occurs that when the bicycle is in a leaning position the lamp will smoke or have the oil run out of the same due to the provided with means for securing it to the bicycle, and the other the complementary disk B, which carries the arm upon which the lamp is secured. These two disks are preferably provided with ball-bearings E between the same, so that the disks may rotate with as little friction as possible. While the ball-bearing is a preferred feature, it is not strictly essential, as an ordinary bearing will in a measure accomplish the same purpose. The essential object desired is to form a pivot which shall cause as little friction as possible and which extends'in substantially a horizontal position. As the device is attached to the steering-head of a bicycle, the pivot will not be strictly horizontal, but will be slightly inclined. This, however, is near enough to a horizontal position to answer the purpose. The disk A is provided with some form of clamp by which it may be secured to that portion of the bicycle-frame upon which it is desired to support the lamp. The clamping mechanism herein shown consists of the band C, which is adapted to surround the head H and has its ends brought together by a clamping-bolt O. The inner surface of this clamp is lined with a layer G of leather, felt,0r similar substance adapted to protect the bicycleframe from injury by contact with the band. If the bracket is to be attached to some other portion of the frame, a clamping device suitably constructed for such purposes is to be substituted for the ring 0. The two adjacent faces of the disks A and B are provided with circular grooves adapted to receive-the balls E, and the two disks are held together by a bolt F, which passes through one disk and screws into the other. The clamping-band O is secured to the disk A or to the bolt F, as shown in the drawings, by means of a small screw or in any other suitable manner.

The two disks A and B are preferably incased in a circular band 1), which prevents access of dirt to the ball-bearings. B is attached an arm I by means of pins f or by other suitable means. This arm extends forward and downward and is adapted to enter the socket L, provided upon bicycle-lamps for that purpose. The lamp may be secured To the disk upon this arm by turning the set-screw M,

which is usually provided upon such lamps. To insure the lamp against jarring off the bracket, the arm is preferably provided with a spring J at the lower end of the arm and which extends upwardly and at a slight angle from the arm. Intermediate its length the bracket until it has passed far enough through the socket to clear the shoulder K. It then spriugsout,so as to engage the under side of the socket and prevent the lamp from falling off. This pivotal suspension of the lamp will hold the lamp always in an upright position no matter what may be the position of the bicycle. The lamp will therefore not be as liable to smoke as it will where it is held A bicycle-lamp bracket, comprising two parts rotatable one upon the other, one part being attachable to the bicycle and the other having a depending arm, said arm having a spring-catch located at its lower end, and a shoulder formed upon said catch intermediate its length and adapted to engage the lower edge of the lamp-socket, substantially as described.

3. A bicycle-lamp bracket, comprisingtwo parts rotatable one upon each other, one partbeing attachable to the bicycle and the other having a depending arm provided with a spring-catch engageable with the lamp-socket, substantially as described.

Y CHARLES E. WI-IITMARSH.
