L. J. ATWOOD. BICYCLE LAMP SUPPORT.

Patented Augvw, 1897.

UNITED STATES PATENT OFFICE.

LEIVIS J. ATWOOD, OF WVATERBURY, CONNECTICUT, ASSIGNOR TO THE PLUME & ATWOOD MANUFACTURING COMPANY, OF SAME PLACE.

BICYCLE-LAMP SUPPORT.

SPECIFICATION forming part of Letters Patent No. 587,912, dated August 10, 1897.

Application filed January 6, 1897.

To all whom it may concern.-

Be it known that I, LEwIs J. Atrwooma citizen of the United States,residin g at Waterbury, in the county of NewHaven and State of Connecticut, have invented an Improvement in Bicycle-Lamp Supports, of which the following is a specification.

The front fork and the parts connected therewith in a bicycle are usually at a backward inclination, but the lamp that is connected to these parts should be held vertical.

, To effect this object, I make the lamp-post with'an angle or bend, so that the lower part of the same may be connected with the fork or other inclined portion of the frame and be parallel therewith and the upper part of such lamp-post will be vertical, or approximately so, and thereby be adapted to the reception of the lamp-socket.

Lamp brackets or supports have heretofore been made for clas ping either the bicycle fork or the frame, especially the front pivot-tube of such frame, but difficulty has arisen in adjusting the lamp upon the frame and clamping the support to the frame simultaneously and by one device. I make the lamp-support with two parts that act in connection with a screw for clamping the fork of the front wheel or the pivot-tube or other portion of the frame of the cycle, and I provide a socket, extending forward of the clamp, to receive the lower end of the lamp-post, and a separate screw is employed for clamping the lamppost within the socket.

I prefer to make the lower end of the lamppost as a ball and to recess the socket and to form such socket of two plates, one or both of which are hinged to the clamps that connectthe lamp-support to the cycle frame or fork.

In the drawings, Figure l is a side elevation, and Fig. 2 is a plan View, of the clamp complete. Fig. 3 shows the parts at one side of the clamp as separated. Fig. 4 is a modification of the socket-plates, and Fig. 5 represents the clamps at one side as made in one piece. I

The lamp-post A is formed with an upper part 2 as a plate or bar to enter a socket upon the back of the cycle-lamp, and the lower part 3 of the lamp-post is preferably round Serial No. 618,136. (No model.)

and adapted to pass into a socket between the plates B B,.and there is a screw C to set up the socket-platesB B and clamp the lamppost between them.

When the lower end of the lamp-post is made as aball'; the plates B B are recessed to receive such ball into such recesses, and the screw C serves to clamp such ball or lower end of the lamp-post and hold it firmly in position after the lamp has been applied upon the upper part 2' of the lamp-post A and set in the desired position. i

The clamps D D are made advantageously of sheet metal and have through them the screw E, by which the outer or moving ends of the clamps can be pressed toward each other to grasp and hold upon the cycle-frame or upon the steering-fork; and with this object in view two recesses of different sizes are made in each clamp D D, the recesses 5 being at the back end of the clamps and especially adapted to grasping the steering framefork, and the recesses 6 are adapted to grasping the pivot-tube of the handle-bar.

It is advantageous to connect the clamps D D by pivots 7 directly to the socket-plates B B and so as to form pairs of plates similar to hinges, and the bars F are employed for connecting the pivots 7 together, and it is advantageous to provide a bar at the top and another one at the bottom, the ends of the pivot-pins being riveted up to retain the parts in position. This gives a convenient connection between the respective parts and at the,

same time freedom by which the respective parts can move in relation to one another. It will therefore be apparent that the socketplate B and the clamp-plate D can be made of one piece, as seen in Fig. 5, the socketplate B and the clamp-plate D being hinged together, as before described. By this construction the bend in the lamp-post approximating the angle of inclination of the front fork allows the upper part 2 to stand vertical, or nearly so, when the lower part 3 is at right angles to the clamping-plates, and hence the adjustment of the lower part of the lamp-post between the socket-plates B B, in order to bring the light in the proper direction, is but small, and the lower part of the lamp-post being circular allows the clamps to be placed at any desired angle to the lamp, so as to be connected to either side of the fork, or for the clamps to extend to the rear of the lamp for Q connection to the pivot-tube of the frame, and while it is usually advantageous to provide the ball upon the lower end of the lamp-post .the same may be dispensed with, as illustrated in Fig. 4that is to say, the lamp-post with a bend may be inserted into a socket or receptacle and clamped therein with the upper end substantially Vertical.

I claim as my invention,

1. The frame-clamps and a screw for actuating the same, and pivotal connections at one end of the clamps, in combination with a lamp-post having a ball at one end and a bend near the middle portion, and socket-plates recessed to receive the ball and pivotal connections at one end to the frame-clamps and a clamp-screw at the other end, substantially as specified. y i

2. The combination with the lamp-post, of a frameclamp and a post-clamp and their screws, a hinge uniting the frame-clamp and post-clamp at one side, and the top and bottom connections F for uniting the hinge to the other side of the clamp, substantially as specified.

Signed by me this 1st day of January, 1897.
