SPECIFICATION forming part of Letters Patent No. 532,336, dated January 8, 1895. I Application filed July 5, 1894. Serial No. 516.615. (No model.)

` such as will enable others skilled in the art to which it appertains to make and use the same. V i

My invention has for its object to provide a lifting device for the chimney galleries of lamps so constructed that the chimney gallery and chimney when released will be moved to the raised position and held there by a spring, a suitable double look being provided on the gallery by which the latter is held at the normal position against the power of the spring. It has been found in practice that it is desirable to have the chimney lifting device self acting but wholly under the controlof the operator, and furthermore that it is desirable to relieve the operator from the necessity of holding the chimney gallery and chimney at the raised position while lighting the lamp.

In order to accomplish these results I have devised the novel chimney lifting device of which the following description in connection with the accompanying drawings is a specification, numbers being used to designate the several parts. i

' Figure 1 is an elevation of a lamp burner illustrating the application thereto of my novel device the chimney gallery being at the lowered or normal position; Fig. 2, a view partly in section showing the chimney gallery at the raised position the lamp having been given a quarter turn; and Fig. 3 is a 'section on the line ma; in Fig. 2, looking up.

l denotes the burner body which is detachably Secured to the lamp collar 2, and is provided on its inner side with a flange 3.

4 denotes the outer air distributer which is Secured to the burner body; 5, the chimney gallery, and 6 standards by which the chimney gallery is carried, and which pass downward within the body. At the lower ends of these standards is an inwardly extending flange 7, and at the inner edge of the flange is a sleeve 8 which slides over the outer wick tube 9 so that the chimney gallery and standards will move up and down steadily in use.

10 is a volute spring lying within the burner body and bearing against flanges 3 and 7, the normal action of which is to lift the chimney gallery toits raised position and hold it there as clearly shown in Fig. 2. In order to retain the chimney gallery at ts normal position against the power of the spring I provide spring latches 11 on the chimney gallery, preferably two placed opposite each other, which are adapted to engage holes 12 in the burner body, one only ot' the engaging holes being shown in the drawings, thereby looking the chimney gallery at its normal, i. e.,its retracted position.

v The special form of spring used insures that the coils close within each other so that no additional space whatever has :to be provided for the spring-there being ample V space therefor between flanges 3 and 7when i the chimney gallery is at the lowered position. It will also be seen that the location and arrangement of the spring makes It removable from the lamp with the burner so that when once assembled the spring is never separated from the burner.

-Another important feature of my present invention is that the construction is such that the operator controls the upward movement of the chimney gallery and chimney, usng but one hand'. In order to accomplish this it is necessary that the looking devices be on the chimney gallery itself, and also to provide locking devices on opposite sides of the chimney gallery which may be readily operated by the thumb and finger to release the gallery, and to enable the operator to control the upward movement thereof. This prevents a sudden upward movement and avoids danger of the chimney being thrown out of .the gallery. In lighting, the operator is simply required to release the latches and control the upward movement of the chimney IOO lamp has been lighted, the engagement of the latches to lock the chimney gallery at the lowered positionbeing automatic.

Having thus described my invention, I claimv In a lanp burner,`the combination with a chimney gallery having standards depending therefrom, and a fiange 7 at the lower end thereof, of a body having a fiange 3, a spring bearing against said fianges and acting to raise the chimney gallery vertically and hold it, and spring latches upon the chimney gallery which act to retain the gallery at its normal position against the power of the spring, and which are grasped by the 15 hand when it is desired to release the gallery, so that the gallery when raised by the spring, is under the control of the operator, and danger of throwng out .the c'himney is avoided.

In testimony Whereof I affix my signature 20 in presence of two witnesses.

FRANK RHIND.
