SPECIFICATION forming part of Letters Patent N o. 575,914, dated. January 26, 1897.

Application tied June 15, 1595. serial No. 595,515. (No model.)

To LZZ whom, t may concern" Beit known that I, AARON P. STORRs, a citizen of the United States, residing at Owego, in the county of Tioga and State of New York, have invented a certain new and useful Improvement in Gas-Lamps, of whichhthe following is a speciiication.

The object I have in view is to produce simple and effective means for supporting gasburners having illuminating-mantles, such as the Welsbach lamp, which will prevent injury to the illuminating-mantle by the shocks and vibrations to which the lamp may be subjected in use. l

In carrying out my invention I introduce between the burner and the nipple of a pillarcock, bracket, or chandelier-arm upon which the burner is mounted a guided springsupport capableV of vertical motion under spring-tension, so as to cushion the eiects of jars in a vertical direction, and upon this support is mounted a rocking head with which the burner is connected, which rocking head permits of a limited lateral movement of the burner. A rubber bulb incloses the supporting parts, making a gas-tight connection with the base of the support and with the rocking head, and permits of the vertical and lateral movements without escape of the gas. This rubber bulb also resists the rocking movement of the head by a spring action which tends to maintain the burner in a vertical position. IVhen the burner is provided with a shade or is in its construction so heavy that the rubber bulb will not normally maintain the vertical position of the burner, a suitable counterweight is attached to the rocking head or to the burner by arms, which maintain the counterweight below the center of gravity, so that the weight will act to maintain the vertical position of the burner.

In the accompanying drawings, Figure lis an elevation of a gas-lamp embodying myimprovement without the counterweight. Fig. 2 is a similar view showing the employment of the counterweight. Fig. 3 is an elevation illustrating the different form of counterweight, especially useful when the burner is mounted on a bracket or on a chandelier-arm and Fig. 4 is a central vertical section, full size, through the iiexible support.

A is aWelsbach or similar burner provided position of the burner.

with the fragile illuminating-mantle, as will be understood.

B is a pillar-cock. Between the burner and the pillar-cock is located the yielding support of my invention.

O is the base-piece of the support, having a screw-threaded openi-ng a, which screws upon the nipple of the pillar-cock. Passing centrally through the top of this base-piece and guided therein is a spindle D, which is supported on a spring E, rest-ing on a shoulder on the base O, the support of the spindle on the spring being by means of a shoulder b.

F is a sleevesurrounding the spindle D and spring E and engaging a screw-thread on the base O. The sleeve F has a cross-piece c at its top to limit the upward movement of the spindle I) and to guide it vertically, and between this cross-piece c and the shoulder b on the spindle is located a spring G. The connection of the sleeve F with the base O by a screwthread permits of the vertical adjustment of the sleeve F, so as to vary somewhat the tension upon the springs E and Gr.

I'I is a rocking head having a conical seat d on its underside and resting upon the pointed upper end of the spindle D, so that it can rock thereon to a limited extent. The head II is provided with a nipple e, which is screwthreaded to receive the base of the burner. Gasways f are formed through the base O and the head I-I to permit the flow of gas to the burner. I is an elastic rubber bulb, the open ends of which are stretched over the base O and the head H and engage with grooves in those the elastic bulb I will be sufficient to maintain the burner normally in a central position. Vhen, however, the burner is heavy or it is provided with a shade K, as in Fig. 2, a counterweight is required to maintain the vertical For this purpose I base of the burner.

lOO

arrangement supported below the center of gravity and tends to maintain the burner in a vertical position. One or more additional rings M may be slipped over the wires g and Will rest upon the Weighted ring L, ifa greater Weight than that furnished by the ring L is required. For brackets and chandelier-arms a weight supported by a single curved arm, as shown in Fig. 3, may be employed.

That I claim isl. The combination with a gasburner, of a yielding spring-support and an inclosin g elastic bulb, substantially as set forth.

2. The combination with a gas-burner, of a guidedyieldin g sprin g-support, and an inclosing elastic bulb, substantially as set forth.

3. In a gas-lamp, a yielding spring-support in combination with a rocking head upon which the burner is mounted, substantially as set forth. i

4;. In a gas-lamp, the combination with a spring-support guided so as to be capable only of a vertical movement, a rocking head connecting such support with the burner, and an inolosing elastic'bulb, substantially as set forth.

5. In a gas-lamp, the combination With the inelosing` elastic bulb I, of the base C, guided spring-spindle I), and the adjustable sleeve F, substantially as set forth.

6. In a gas-lamp, the combination with the elastic bulb I of the base C, spindle D, springs CZ g, sleeve F, and rocking head II, substantially as set forth.

This specification signed and witnessed this 12th day of June, 1896.
