ACETYLEN E-G EN ERATOR AND BICYCLE-LAM P.

SPECIFICATION forming part of Letters Patent No. 566,660, dated August 25, 1896. Application iilecl May ll, 1896. Serial No. 591,022. (No model.)

To all whom t may concern.-

Be it known that I, HENRY B. CLARKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bicycle-Lamps, of which the following is a speciiication.

My invention relates to lamps for bicycles, and has for its object to provide a convenient and simple gas-lamp.

It is illustrated in the accompanying drawings, wherein- Figure l is a side view of the lamp. Fig. 2 is a vertical section. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2.

Like parts are indicated by the same letters in all the figures.

A is the gas-receptacle, the same being formed of a cylinder. It is provided with an inner cylindrical portion B, secured thereto by the lateral arms B. This leaves an an nular space between the two cylinders, which leals to the upper portion of the gas-receptac e.

C is the top of the gas-receptacle, which may be continuous with the body or may be attached to it. It contains the stungbox D and the valve E. This Valve has an inner stem E', a nut E2 on the stein, and a spiral springF, which surrounds the stem and tends to keep the valve forced inwardly anden its seat.

F is a pipe which leads from near the top of the cylindrical receptacle to the lower part of the lamp G. This pipe is controlled by the valve Il. The lamp C consists of the body proper, the reiieotor G' therein, and the glass G2, preferably secured on the door G3. The lamp is also provided with the overhanging dome G4, about the upwardly-projecting cylindrical portion G5. rlhe pipe F opens into the coupling F', whence leads the burner F2, having the minute opening F3.

J is a sliding part on the lamp G to open and give opportunity for lighting the lamp. The door is secured by means of the springcatch K and the pin K'. The lamp is secured at L in any desired manner to the cylindrical receptacle. Secured,and preferably by screwthreads, to the lower part of the cylindrical gas-receptacle is the water-reservoir M.

N is a sliding cylinder held at any desired position by friction within the cylinder B. t has the holes N above the bottoni. At its lower end there is a removable plug O, having the opening O and the thumb-piece O2. At the other end of this movable cylinder is the controlling-rod P, which passes through the stuffing-box D and terminates in the thumb-piece P'. W'ithin the movable cylinder is shown a lump of gas-producing coinposition, (marked R.)

The entire device is preferably secured to the head T of the bicycle by means of the spring-controlled arms S S, whereby it has a slightly-elastic support.

I do not wish to be limited to the precise form and construction of these several parts, as they may be greatly varied without departing from the spirit of my invention.

The use and operation of my invention will be now explained. The composition R is some composition which on being brought into contact with water will generate gas, and it is put into the cylinder and the bottom-piece O is then screwed into position, the substance resting upon bottom and above the holes O O'. The rod P is Jthen introduced through the stufling-box, and the thumb-piece P can be removed for this purpose. The whole is then put into the gas-receptacle and raised to a considerable height. The waterreservoir is then filled with water and screwed into position. Under these conditions no gas will be formed. Then the lamp is in position for use on the bicycle, and it is desired to proceed with the formation of the gas and to light the lamp, the thumb-piece P' may be manipulated so as to gradually force the movable cylinder N downwardly until the substance R is brought into contact with the water. Thereupon gas begins to forni and the operator will control the matter by regulating the degree to which this substance is plunged into the water. The gas will emerge from the holes N' N', and will pass thence out through the pipe F into the burner F2. It is lighted from the side by raising the slide J. The sediment formed from the operation of producing gas is sitted down through the holes O O and precipitated on the bottoni of the reservoir M, so that after the lamp has been used it may be readily cleaned by simply cleaning out this lower receptacle. Then it is desired to discontinue the use ofy the; gas;

the mnvablefcylinder is' raised means of the thumb-"piece P ,and the substance is lifted `out of the Water,s0 that no further gas is opening, with a lower cup-shaped:Wate'nres` ervoir, screw-threaded to the receptacle, an

interior vertically-movable holder for the gas-v forming substance, a rod on the same extend- Iing outthrough the top of theLgas-receptacle,

a guide for the holder Within said holder in the shape of an inverted cup With a removable bottolrn'a safety-Valve in the path of the holder, a lainp screwed tothe front side of the gasreceptacle', alconnection therefrom, to the gasreceptacle, and a spring attachment secured -tothe .opposite side ofthe gas-receptacle, all

substantially as shown' and for the purpose described.
