PROTECTOR-CAP FOR BURNERS.

Specification of Letters Patent.

Patented Sept. 25. 1906.

Application filed May 16,1906. Serial No. 317,215.

To all whmn it may concern.-

Be it known that I, CHARLES T. FULLER, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Protector-Caps for Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in glass protector-baskets for lamps, and comprises a cup made, preferably, of opal glass and adapted to support a globe and so arranged that it will catch any particles of carbon or fire that may drop from the burner and being transparent will avoid the throwing of shadows beneath the same.

The invention consists of various details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which 4 Figure 1 is a sectional view through my invention. Fig. 2 is a detail perspective view of the protector-cup. Fig. 3 is a detail perspective view of the drum which fits over the Bunsen tube. Fig. 4 is a perspective view of the protector-cup-supporting shell, and Fig. 5 is a top plan view of the globe-supporting member.

Reference now being had to the details of the drawings by letter, A designates a Bunsen tube having an air-inlet A, and B is a shell having a set-screw B, mounted in a threaded aperture in the wall thereof, said screw being adapted to bind against the Bunsen tube to hold said shell in an adjusted position. The shell B is provided with a shoulder B having a series of apertures B formed therein, through which air is allowed to enter for ventilation purposes.

C designates the protector-cup, which is made, preferably, of opal glass and has its lower end contracted and adapted to rest upon said shoulder B The upper portion of the cup flares outwardly and is provided with series of beads C, in which sockets are formed for the reception of the spider-arms J, which radiate from the band J.

D designates a burner-drum in which the Bunsen tube telescopes and which drum is adapted to receive the set-screw B, which passes through an aperture which is in registration with an aperture in the shell B. Said drum D has series of lugs D about its circumference, forming a means for supporting the band J. Rising from said arms J are the resilient fingers I, which are adapted to engage the lower contracted end of the globe H and hold the same securely in place.

When the parts are adjusted in place as shown and described, it will be observed that the protector-cup will surround the parts intermediate the globe and the burner-drum and afford means for catching any particles of carbon or other foreign matter which might fall from the burner and being made of opal glass will avoid the casting of shadows which is usually the case with opaque devices which may be utilized for this purpose.

What I claim is- 1. In combination with a Bunsen tube, a shell and a burner-drum adj ustablyheld upon said tube, a transparent protector supported by said shell, lugs projecting from the drum, and a globe-holder supported by said lugs, as set forth.

2. In combination with a Bunsen tube, a shell and a burner drum adjustably held upon said tube, a transparent protector supported by said shell, lugs projecting from said drum, a globe-holder supported by said lugs and having arms projecting therefrom, the ends of said arms engaging sockets formed in said protector-cup, as set forth.

3. In combination with a Bunsen tube, a shell and burner-drum secured thereto, said shell having a shouldered portion which is provided with vent-apertures, a transparent protector cup resting upon said shoulder within the shell, and a globe-support mounted upon said drum, as set forth.

4. In combination with a Bunsen tube, a

"shell and burner-drum secured thereto, said shell having a shouldered portion which is gers rising from said arms adapted to engage provided with vent-apertures, a transparent a globe, as set forth. r0 protector-cup resting upon said shoulder In testimony whereof I hereunto aflix my within the shell, lugs projecting from said signature in the presence of two witnesses. drum, a globe-supporting shell resting upon CHARLES T.
