LAMP.
SPECIFICATION forming part of Letters Eatent No. 615,666, dated December 6, 1898.
Appllcatlon filed August 31, 1898. Serial No. 689,968. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS LANGSTON, a citizen of the United States, residing at Meriden, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description.
My invention relates to lamp construction; and one of my objects is to provide an adj ustable support for the wick in the fount, so that the lamp will go out after the oil has been consumed down to a level 3' net below said support.
Other advantages of my invention will be evident from the specification and the accompanying drawings of the preferred embodiment thereof, in which- Figure 1 shows in central vertical section of Fig. 2 a lamp-fount constructed according to my invention. Fig. 2 shows a top plan view thereof, and Fig. 3 shows a detail view.
In the illustrated preferred embodiment of my invention, A is the fount of the lamp, comprising an outer oil-receptacle B and an inner oil-receptacle C,connected by an extended oil-passage D. Between the inner and outer oil-receptacles is an air-draft passage E. F is a burner of a lamp having a wick-tube G and a wick H. In the inner receptacle is a shelf K, vertically movable in this receptaole, to which is attached a bent rack-rod L, passing through said extended passage, engaged by a pinion M, as shown, and said pinion is operated by a thumb-wheel N and shaft 0. This thumb-wheel has aperturesP therein, which the bent end of a spring R is adapted to enter to lock the same. This rackrod, as shown in Fig. 3,is preferably numbered as shown, said numbers being arranged as specified hereinafter. The shelf, and consequently the wick,-may be raised or lowered by turning a thumb-wheel, and if the same is raised up to the position shown in dotted lines in Fig. 1 the lamp will go out after the oil has been consumed down below the level of the wick when in that position. If the shelf is lowered still farther, the lamp will burn longer before going out, and the relative position of the shelf, and consequently of the wick in the fount, and obviously the consequent time of burning of the lamp, may be indicated by the numbers on the rack-rod, which show just above the guide S from said rod. In the present embodiment Ihave numbered the rod by hours, so that if said rod is lowered until the number 11 just shows above the top of guide S it will be understood that the lamp will burn until eleven oclock, if lighted, say, at eight oclock, by which time the oil will have dropped below the shelf and wick, as a consequence of which the lamp will go out of its own accord. The rack, and consequently the shelf and wick, may be located in any desired position by the spring R engaging with the thumb-wheel, as shown.
It will be obvious that very many modifications of the construction herein shown and described may be made without departing from the spirit of my invention.
What I claim is- In a lamp in combination a double fount said fount having an outer and an inner oil receptacle forming an air-draft passage between the same, an extended oil-passage connecting the two, a burner and wick-tube over said oil-receptacle, a shelf in said fount adjustable vertically and adapted to carry a wick, a rod attached to said shelf, extending therefrom through said extended oil-passage and outside said fount, and adapted to manipulate said shelf, said rod having timemarks thereon to designate the relative position of said shelfin said fount.
Signed at Meriden this 27th day of August,
THOMAS LANGSTON. Witnesses:
