SPECIFICATION forming part of Letters Patent No. 755,685, dated March 29, 1904.

Application filed June 25, 1903. Serial No. 163,045. (No model.)

To all whom/it may concern.-

Be it known that I, LEO MONTEL, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in'Lamps, of which the following is a specification, reference being'had to the accompanying drawings, forming a part hereof.

This invention relates to lamps, and particularly to lamps provided with reflectors, such as are commonly employed for head or side lights upon vehicles. It is usually desirable that these lamps shall be made with the lantern' or reflector portion detachable readily from thelamp-body, such construction rendering the cleaning of the lamp and the lantern more easy and making it possible to use the lantern upon another lamp-body or to use the lamp-body detached from the lantern when desired, besides being preferable for other reasons. acter it has been customary to secure the burner to the reflector, and consequently when the reflector is to be separated from the lamp the gas-pipe between the burner and the gas-supply has to be severed at some point. This severing has commonly been eifected heretofore by providing a rubber pipe or some such device which served as a connection between the burner within the lantern and the gas-supply pipe upon the lamp-body, and when the lantern was to be detached from the lamp-body this rubber or other connection had to be first removed from one or the other of-the pipes which it connected. Such an arrangement is undesirable, chiefly because it renders the attaching and detaching of the lantern more or less of a clumsy operation, and, furthermore, when a rubber pipe is used it soon wears out or gets broken or jammed, and consequently has frequently to be replaced.

The object of this invention is to provide an improved means for securing the lantern to the lampbody,whereby it may be easily and In gas-burning lamps of this char quickly attached or detached, as desired, and whereby the connection between the gas-supply and the burner in the lantern is automatically made and severed, thus not only obviating the necessity of rubber pipe, but by means of which the connections between the burner and the fuel-supply are made and severed by simply attaching or detaching the reflector that is, automatically.

in the drawings, in which the invention is illustrated as applied to the gas-lamp, Figure 1 is a View in front elevation of a lamp-body with the lantern detached and removed. Fig. 2 is a rear elevation of the detached lantern, partly broken away to show the burner. Fig. 3 is a side elevation of the combined lamp and lantern, a portion of the View being in section to illustrate the means of attachment; and Fig. 4c is a view in rear elevation of the lamp-body, said body being partly in section to show the connection between the fuel-supply pipe and a fuel-supply conduit.

' The lantern. a, which may be of any preferred form, has secured therein a burner b and a reflector 1", (shown clearly in Fig. 3,)

both of which may also be of any preferred form. A pipe 0 extends from the burner to the exterior surface of. the lantern, where its open end 03 is adapted to. receive a nipple upon the lamp-body f, said nipple resting within the open end 01 of pipe 0 when the lantern is in place upon the lamp-body, as shown in Fig. 3.

To support the lantern upon the lamp-body, said lantern is provided with a lug g, which fits in a hole in a bracket it upon the lampbody, the position of the lug -and-bracket connection being such that the nipple a will register with the opening d in pipe 0 when the lantern and lamp-body are brought together. To fasten the two parts together, a pin-andsleeve connection 2' j is provided, the sleeves i being secured to the lamp-bodyand lantern and the pin 4' being adapted to be inserted within the sleeves when the two parts (the lamp-body and, the lantern) are united. The

lantern is thus detachably secured to the lampbody and may be easily and quickly removed therefrom and attached thereto.

The lamp comprises an outer inclosing body f and an inner inclosed shell is, secured to the outer body by thumb-screws l, and these lamp parts may be of any suitable form or construction. WVhen an acetylene-lamp is used, for instance, the outer body will preferably contain water and the inner shell the carbid and generated gas. A fuel-supply pipe m, projecting from thetop of the inner inclosed shell, is bent over so thatits free end projects downwardly, and when the shell is placed into the outer body the end of said pipe is inserted into an opening a in the upper part of the outer body, said opening forming the upper end of a fuel-supply conduit for conducting fuel to the detachable burner b. A rubber washer 0 or other packing is provided for the end of pipe m in order to form a tight joint between said pipe and the upper end of the fuel-supply conduit. This fuel-supply conduit may comprise any suitable form of fuelconducting means from the opening at to the nipple c. In'the present case said conduit comprises a pipe p, leading to a channel 8 upon the bottom of the body f, said channel communicating with another channel, t, upon the exterior of body f and from which the nipple 0 projects. To form a tight joint between the nipple e and pipe 0, a rubber washer u or other suitable device may be provided around the end of the nipple.

It will be obvious that when the lantern is to be attached to the lamp-body the lug g upon the lantern is inserted into the hole in bracket it upon the lamp-body. The sleeve is then brought between the two sleeves upon the upper part of the lamp-body and the pin j is inserted within the sleeves. This will cause the nipple c to be inserted into the end of pipe 0, -the washer around the nipple 6 serving to form a tight joint between the fuelsupply conduit and the pipe leading to the burner. When the fuel-containing shell is is placed into the lamp-body or when it is withdrawn therefrom, the free end of the fuelsupply pipe m is at the same time inserted into and withdrawn, respectively, from the upper end of the fuel-supply conduit, a tight joint between the pipe and the conduit being made by the packing 0.

It will be understood that the invention is not limited to the specific form shown in the drawings, nor is its application restricted necessarily to its use in gas-lamps. It will also be understood that the part herein referred to as the lantern may, so far as the means of attachment are concerned, he simply a reflector, or, so far as the automatic connections between the fuel-supply and the burner are concerned, be simply a burner.

I claim as my invention- 1. In a lamp, a lantern detachable from the lamp-body, a fuel-supply conduit in the lampbody one end of which extends tothe exterior of the lamp-body, a pipe within the lantern communicating with the burner therein and extending to the exterior of the lantern, the ends of said conduit and pipe being brought together to form a continuous conduit when the lantern is in place upon the lamp-body.

2. In a lamp, a lantern detachable from the lamp-body, a fuel-supply conduit in the lampbody one end of which extends to and terminates in a nipple upon surface of the lampbody, a rubber washer around the nipple, a pipe within the lantern communicating with the burner therein and extending to and terminating in the exterior surface of the lantern, the nipple being adapted to fit into the end of the pipe when the lantern is in place upon the lamp-body.

3. In a lamp, the combination with a lantern detachable from the lamp-body, and means for securing the lantern to the lampbody,which means comprise a lug-and-bracket connection and a pin-and-sleeve connection, of a fuel-supply conduit in the lamp-body one end of which extends to the exterior of the lamp-body, a pipe within the lantern communicating with the burner therein and extending to the exterior of the lantern, the ends of said conduit and pipe being brought together to form a continuous conduit when the lantern is in place upon the lamp-body.

4. In a lamp, the combination with a lantern detachable from the lamp-body, means for securing the lantern to the lamp-body which means comprise a lug upon the lantern, a bracket upon the lamp-body adapted to receive the lug, sleeves upon the lantern and lamp-body and a pin adapted to be inserted into said sleeves to fasten the lantern to the lamp-body of a fuel-supply conduit in the lamp-body one end of which extends to the exterior of the lamp-body, a pipe within the lantern communicating with the burner therein and extending to the exterior of the lantern, the ends of said conduit and pipe being brought together to form a continuous conduit when the lantern is in place upon the lamp-body.

5. In a lamp-body having an outer inclosing body and an inner inclosed shell, a fuelsupply conduit within said outer inclosing duit within the outer inclosing body both ends of which conduit terminate substantially in the surface of the outer inclosing body,a fuelsupply pipe projecting from the inner inclosed shell the free end of which is adapted to be inserted into one end of the fuel-supply conduit, and a burner upon but detachable from the outer inelosing body and communicating with the other end of the fuel-supply conduit. 10
