SPECIFICATION forming part of Letters Patent No. 703,769, dated July 1, 1902.

Application filed February 26, 1901. fierial No. 48,650. (No model.)

To aZZ whom, it may concern;

Be it known that I, GEORGE ERWI DE LONG, a citizen of the United States, anda resident of the city, county, and State of New York, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification. V

My invention relates to motor-vehicles, and more particularly to motor-cycles.

[0 My invention has for an object to do away with the auxiliarycasings and attachments ordinarily removably secured to the frames of motor-cycles, and thus to greatly reduce the Weight and improve the appearance thereof.

Other objects of my invention are to improve and simplify the construction of motor-cycles and render them more practicable and more convenient in use.

My invention consists in the novel parts,im-

2o provements, and combinations herein shown and described.

The accompanying drawings, which are referred to herein and form a part hereof, illustrat-e one embodiment of my invention and 2 5 serve,in connection with the description herein, to explain the principles of my invention and the best mode in which I have contemplated applying those principles.

Of the drawings, Figure 1 is aside eleva tion, partly in section, of a motor-cycleconstructed in accordance with my invention. Fig. 2 is a sectional view, on an enlarged scale, illustratinga detail of the construction. Fig. 3 is a sectional elevation taken on the line 3 3 of Fig. 1.

In carrying out my invention I construct a hollow or tubular frame and form the receptacles for the fuel-supply and other adjunctive devices of the motor within the hollow or tubular sections of the frame. I preferably use a gasolene-motor of the De Dion type, the explosive mixture for which is supplied by means of a carburetor of the atomizing type and the igniting devices of which consist-of one 5 or more battery-cells and a sparking coil. In

the drawings I have illustrated my invention as applied to a bicycle having a tubular frame of the ordinary diamond pattern.

Referring now to the drawingsin detail, 1 represents the motor, which preferably and as shown is located directly above the main or crank shaft 2 of the bicycle, the upright brace 3 of the frame being to this end divided at its lower portion into two or more branches or members, between which the motor 1 is secured. As shown, two branches 4 and 5 of the upright brace are provided at the rear of the motor and are made to conform to the general Outline thereof. These branches 4 and 5 are secured at their lower ends to the branches or members 6 and 7 of the lower rear brace of the frame, preferably at or near the point where these members are secured together by the usual transverse brace 8, which is arranged just in advance of the rear Wheel of the bicycle. By reason of this construction the motor and crank-bracket are brought as near as possible to the rear wheel of the bicycle, and the wheel-base of the latter is therefore not unduly extended. A third branch or member 9 of the upright brace 3 is arranged in front of the motor and is preferably secured at its lower end to the lower forward brace 10 of the motor frame. A transverse brace 11 is arranged near the top or head of the motor and acts to secure the same in place and to strengthen the branches 4, 5, and 9 of the upright brace 3.

The power-shaft of the motor is provided with a small pinion 12, which meshes with a larger pinion 13 on the crank-shaft 2. The opposite end of the shaft 2 is provided with a small sprocket-wheel 14, which connects with another sprocket-wheel 15 on the rear wheel of the bicycle by means of a chain 16. The crank-shaft is preferably provided with a suitable clutch, so that it may be held from rotation by the rider when the bicycle is being driven by the motor, as is usual in motor-cycles. As the details of this clutch mechanism 0 do not form a feature of my present invention, they have not been shown and need not be further described.

In the construction shown the upper for ward brace 17 of the frame is constructed and 5 arranged to form a receptacle for the fuel-supply of the motor. To this end the brace 17 is closed at its forward end, where-it is secured to the head 18 of the frame, and the upper end of the upright brace 3 and the coupling-piece or bracket 19 are so secured together and to the rear end of the brace 17 as to form a liquidtight connection and to constitute a part of the fuel-supply receptacle, a suitable passage being provided between the braces 3 and 17. A closed socket-tube 21 is provided in the upper end of the brace 3 to receive the seat-post 22, as shown. The brace 17 is provided, preferably at its forward end, with a capped opening 23, whereby the receptacle formed in the brace maybe supplied with fuel. The carbureter for the motor is preferably formed in the brace 3 just above the motor. The carbureter shown comprises a supplypipe 24, curved at its lower end, so as to discharge the liquid fuel upwardly. A valve 25 is arranged in the supply-pipe, the controlling-handle of which is arranged outside of the brace 3 within easy reach of the rider. An opening 26 is arranged above the discharge-opening of the fuel-supply pipe 24 to admit the supply of air. The opening 26 is provided with a suitable regulating-valve 26 to control the supply of air. A perforated plate or screen 27 is arranged below the'fuelsupply pipe and the air-opening, and a passage 28 is arranged below the screen 27 to convey the explosive mixture from the carburetor to the motor. A relief-cock 29 is arranged at one side of the top of the motor in position to be easily reached by the rider. The exhaustpipe 30 of the motor is preferably arranged at the back thereof and between the members 4 and 5 of the upright brace, the lower end of the exhaust-pipe terminating in a muffler 31, which is arranged between the members 6 and 7 of the lower rear brace of the frame and just in advance of the transverse brace 8.

The igniting devices of the motor are pref erably and as shown arranged in the lower forward brace 10 of the frame. To this end the brace 10 is extended at its lower end beneath and beyond the bracket which carries the main shaft 2 of the motor, so that the igniting devices may be inserted therein and removed therefrom. The igniting devices preferably consist of a sparking coil and a plurality of battery-cells 36. As shown, an insulated contact piece 37 is permanently fixed at the upper end of the brace 10 and the sparking coil 35, and each of the batterycells 36 is provided at each end with a contact-piece, so that when they are put in place in the brace 10' and the lower end of the latter is closed, as by the screw-cap 38, the electric connections from the contact-piece 37 through each of the said elements of the igniting devices to the frame of the motor through the cap 38 is made complete. The contactpiece 37 is connected with an insulated wire 39, which passes through the head of the frame to a suitable switch 40, located on the frame within easy reach of the rider. The switch 40 may be connected with the usual circuit-breaker on the motor (not shown) in any suitable manner. As shown, an insulated wire 41 passes from the switch 40 down through the head of the frame and then through the lower forward brace 10 at one it may obviously be located at any convenient point on the machine, as in one of the grips of the handle-bars.

It will be noted that aside from the motor there are no attachments secured to the out side of the frame of the bicycle. There are no casings or receptacles to mar the appearance of themachine or to be loosened by the vibrations thereof While on the road. It will be noted also that all the extra weights of the casings or carriers usually employed in motor-cycles are dispensed with, the tubular braces of the frame itself being made to take their places. All parts of the apparatus are securely held in place, and the construction in general is simple and compact and not apt to get out of order.

My invention is not limited to the precise construction shown or to the precise construction by which it maybe carried into effect, as many changes may be made therein without departingfrom the principles of my invention or sacrifice its chief advantages.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
