SPECIFICATION formingpart of Letters Patent No. 738,689, dated September 8, 1903.

Appli oation'filed March 1 902. Serial No. 98,327. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM F. LoUnoN, a citizen of the United States, residing at Stoning-ton,in the county ofNew London and State of Connecticut, have invented certain new and useful Improvements in Lamps 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.

The present invention relates to improvements in lamps, and more particularly to certain improvements in that type of'lamp in which the kerosene is formed into a vapor or gas previous to being ignited and which are generally known as hydrocarbon-burners. The object of the present invention is to so construct the lamp that the globe thereof may be readily placed in position or removed there- 3 vented from rattling while the lamp is in use; p

from and be held firmly in position and preand a'further object of the invention is to provide means for'regulating the admission of air to the dome of the lamp.

To the above ends the present invention I consistsrof the devices and. combinations of f devices which will be hereinaftar described pump may be attached to place'the oil in the tank a, under pressure sufficient to force it up the pipe 0 to thevaporizing devices contained in the dome d, from which it is led downthe pipe" e in the form of a gas or vapor to the burner f, all as will be clearly understood by those persons skilled in this art.

The device as so far y described is of the usual and ordinary construction and in and of itself forms no part of the present invention. I

A glass globe g surrounds the burner and the flame and at its lower edge rests upon a circular table h, which is provided with a groove (not shown) in which the lower edge of the globe g fits. The upperpart of the globe g is of a diameter substantially the same as the diameter of the lower part of the dome, and, as shown clearly in dotted lines, encircles and receives the lower part of the dome,

the arrangement being such that when the p parts are adjusted as shown in Fig. l of the drawings the globe 9 will be firmlyheld in position on thetable 'h.

Surrounding the dome d is a metallic cap or shade 2', having an opening j, which is substantially the. diameter of the dome d and gradually flaring outwardly toward its base. This cap 1' is arranged to slide up and down along. the dome d, its normal position when the globe g is in place being shown in full lines in Fig. l and resting upon the upper edge of the globe When it is desired to remove the globe g, the cap t' is moved upward to the position shown in dotted lines, and I have provided suitable means-such as a spring-latch 70, having a hooked end arranged to take over a bead or rib Z-at the upper edge of the dome, whereby the cap will be held in dotted-line position while the globe g is being removed or replaced- For the purpose of facilitating the removal of the globe g I have pivotally mounted the dome (1 upon the inturned upper ends of the pipes e and 0, so that said dome may be tilted, as shown in dotted lines, Fig. 2, and before the globe 9 can be removed the dome cl must be moved to the position shown in dotted lines. In order to maintain the dome d in the full-line position shown in Fig. 2 and to prevent its accidental tipping, I have provided the same with a latch on, having a in dotted lines, Fig. 1, whereupon the dome 01 will be tilted, as shown in Fig. 2, permitting the ready removal of the globe g.

The dome dis provided with an opening 10, which may be closed by a suitable sliding plate (not shown) whereby to permit the entrance of a match orother light to ignite the Vapor forming the light.

It is desirable in lamps of this kind to regulate the admission of air to the vaporizing apparatus, the air entering the dome d at an opening surrounded by a cup-shaped or an nular disk g, and I have provided a cap or cover 4', having athreaded opening arranged to engage a short threaded section 8 on the upper end of the pipe e, the arrangement being such that the cap 1" may be adjusted to and from the cup-shaped disk g. By this means I control the flow of air to the vapor- 1 l0 izing apparatus.

The operation of my invention has been sufficiently set forth in connection with the foregoing description of its form and arrangement, and a further description thereof is deemed unnecessary.

Having described my invention, I claim as new and desire to protect by Letters Patent of the United Statesing said upright standards, and a 'latch secured to the dome and adapted to engage said transverse member, substantially as described.

2. A lamp: provided with a table, a globe resting upon said table, a dome engaging the upper end of the globe, an elongated rib upon said dome, a shade slidingly fitted upon said dome and normally resting upon the globe, and a latch mounted upon said shade and adapted to engage the rib for holding the shade raised, substantially as described.

'3; A lamp provided .with a table, a globe resting on said table, a dome pivoted to upright standards and engaging the upper end of said globe, a transverse member connecting said upright standards, a latch secured to the dome and adapted to engage said transverse member, a shade slidingly fitted upon said dome and complementary latch elements secured to said dome and to said shade Whereby the shade may be held in an elevated position, substantially as described.

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

WILLIAM F. LOUDON.
