GAS-LAMP.

Specification of Letters Patent.

Patented July 21, 190s.

To all whom 'it may concern.'

Be it known that I, ALooRN RECTOR, of the city, county, and State of New York, have invented a new and Improved Gas- Lamp, of which the following is a full, clear, and exact description.

My invention relates to improvements in incandescent gas lamps and more especially to improvements in the inverted lamps socalled in which a depending mantle is used and the gas and air are forced downward into the mantle. An objection to most lamps of this kind is that it is diflicult to ap ly the mantles to the lamps for the reason tliat the burner or pipes are in the way and as the mantles are extremely fragile one is quite' likely to injure them in placing them upon the lamp.

The object of my invention is to obviate this difficulty and produce a lamp in which the mantle carrying part and the gas delivering part are separable so that when se arated or reculty, after which the partscan be readily placed in the proper relation for use. Obviously this result can be obtained in uite a number of Ways and in the drawings have shown several methods to make it clear that my invention is not confined to any precise form of burner in which the delivery art and/the mantle carrying part are separa le.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the lamp embodying my invention with the head and gas pipes raised from the mantles; Fig. 2 is a broken side elevation of a slightly modified form of the invention showing also the parts separated Fig. 3 is a broken side elevation of another modification of the lamp in which the arts are applied to the usual upright gas jet; ig. 4 shows in side elevation the application of the principle to the so-called gas 4arc lamp.

Referring to Fig. 1, the bunsen 10 is rovided with a supportin pin 11 or equiva ent which sup orts the sli ing yoke 12v and this is attachedp to the sleeve 13 and has rings 12a which are adapted to support the legs 14a of ,which moves nlp the inverted mantles 14. The mantles, as is Well known to the trade, are usually provided with rings of magnesium or other material at the to having le s 111a which fit in sockets on the urner headgs, but in this case the legs 14a which are exactly as usual, rest in sockets in the rings 12a. The sleeve 13 is provided with a bayonet slot 15 which is adapted to connect with a pin 16 near the top of the tube 17 which forms an extension of the bunsen 10, so that when the sleeve 13 is raised and locked to the pin 16 the mantles will be in the position shown in dotted lines in Fig. 1, so as to receive the gas and air from the tubes 'or pipes 19 which extend downward from the head 18 on the upper part of the stem or tube 17 Obviously other fastening-means can be used for connecting the sleeve 13 to its guide and supporting stem without aifecting the princip e of the invention.

In Fig. 2 I have shown a sight modifica` tion of the device in which the rings 12EL are rigidly supported at the top of the tube 17 by arms 12 which are attached to the tube and the top ofthe tube is referably widened slightly as at 17?. In this case the head 18 has the depending tubes 19 as shown and it has also a pipe 20 which is tapered as at 2()EL so as to iit into the part 17a of the tube 17. In this structure the head 18 and tubes 19 are lifted off, thus leaving the mantles 14 free and clear so that they can be readily removed from or inserted in the rings 12a. The structure shown in Fig. 2 and the structure shown in Fig. 1 can be attached to any ordinary gas pipe and used with any preferred ty e of glass ware or globe.

In Fig. 3 I have shown a slight modification of the invention applied to the ordinary vertical et and with a single inverted mantle 14 which is carried as already described, and the single ring 12aL is attached to the sleeve 13 and down on the stem 17, as in Fig. 1, but t e stem or tube 17 has a single bend 19a and has a pin 16 as already described. The sleeve 13 can be dropped downward into contact with the supporting pin 11 or it can be pushed up to have the in 16 locked into the bayonet slot 15 in the former case the mantle being lowered to permit ready access to it and in the latter the mantle being raised ready for lighting.

In Fig. 4 I have shown a structure analogous to the so-called arc lamp, this term being ap lied to groups of mantles which are genera ly inclosed by a single globe to Give an arc light ei'ect, and in this case a pluraity of stems 17 are used having the iiXed rings 12 as already described, but the stems each deliver into an inverted U-shaped pipe or tube 19b which can be placed on or removed from the tube 17 and by removing it the mantle is left free and by placing it in position the lamp is ready for lighting.

I have shown these several modiiications to illustrate the fact that there are very many ways of separating from each other the pipe which delivers the gas and air, and the mantle. Obviously any approved form of bunsen can be used and any ordinary or preferred type of' mantle, and it will be seen that my invention is not coniined to any particular means of separating the mantle and delivery pipes.

It will be observed that in the several views I have shown rings in which the mantles can be deposited by simply dropping them through the rings, and this is important because where the mantle has to be pushed upward into some sort of a holder, it is very likely to be broken during the operation.

Having thus fully described my invention, l claim as new and desire to secure by Letters Patentr- 1. In combination, a Bunsen tube, a bracket carried by the Bunsen tube, a mantle carried by the bracket, and a pipebent into an approximate U-shape engaging the top of the Bunsen tube, and discharging within the mantle, said pipe being removable independent of the Bunsen tube and the mantle.

2. ln combination, a Bunsen tube, a bracket carried by the Bunsen tube and extending to one side thereof, a mantle carried by the bracket and a pipe removably engaging the top portion of the Bunsen tube and discharging within the mantle, said pipe being removable independent oi' the Bunsen tube and the mantle.

3. In combination, a Bunsen tube, a bracket carried by the Bunsen tube, a mantle carried by the bracket, and a pipe bent into an approximate U-shape and supported on said Bunsen tube, and discharging within the mantle, said pipe being removable independent of the Bunsen tube and the mantle.
