CAR-LAM P.
SPECIFICATION forming part of Letters Patent No. 636,889, dated November 14, 1899. Application iiled August 14;, 1899. Serial No. 727,195. (No model.)
To .all whom it may concern:
Be it knownthat I, EDWIN A. BENSON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Oar-Lamps, of which the following is a specification.
This invention relates to that class of carlamps which are provided with a central gaspipe carrying at its lower end a burner which is inclosed by an upper stationary globe and a lower hinged globe, which latter can be released and swung down when access is required to the burner forlghting or other purposes. Sometimes cars provided with such gas-lamps are run over railroads where gas cannot be procured, and in that case it is necessary to substitute oil-lamps for the gaslamps.
The object of this invention is the const-ruction of an attaching device which permits this substitution to be made in a simple and convenient manner.
In the accompanying drawings, Figure lis an elevation ofa gas car-lamp of the wellknown Pintsch system. Fig. 2 is an elevation showing the lamp converted into an oillamp. Fig. 3 is a vertical section, on an enlarged scale, showing the upper part of the oil-pot andthe devices by which it is attached to the upper globe of the gas-lamp. Fig. 4.
is a horizontal section in line 4 4, Fig. 3, showing the detachable .fastening of the oil-pot, the oil-pot and the gas-pipe being omitted. Fig. 5 is a side elevation of the same. Fig. 6 is a vertical section in line 6 6, Fig. 4, on an enlarged scale. Fig. 7 is ahorizontal section, on an enlarged scale, of the divided collar by which the lamp-shades are secured to the stem of the gas-lamp above the globe thereof, the section being taken in line 7 7, Fig. 2. Y
Like letters of reference refer to like parts in the several gures.
A represents the pendent stem or top portion of the housing of a gas car-lamp of the kind used in the well-known Pintsch system of lighting. B represents the upper translucent globe, which is rigidly secured to the lower end of the stem and forms the lower part of the housing, which is open at its lower end and provided with a metallic ring b. O
is the lower transparent glass globe, which is provided at its upper large end with a metallic ring c. The latter is attached to the ring b at one side by a spring-catch D and at the opposite side by a hinge d, so that upon releasing the catch the lower globe swings down on the hinge and exposes the burner. c represents the gas-pipe,which extends downwardly from the ceiling of the carthrough the stem A and globe B and carries at its lower end the burner E, which is located in the lower globe O. F represents the central reflector, and F the outer reflector, arranged in the upper globe and provided with the usual passages for the supply of air and the escape of the products of combustion. .All of these parts are of ordinary and well-known construction.
Gr represents the oil-pot of an oil-lamp of the kind usually employed for the illumination of railroad-cars. This pot is provided at its lower end with two horizontal branches g, which carry the burners g7 and their accesseries, such as the wick-tube housings g2, chimney-galleries g3, and chimneys g4. These oil-lamps are of the well-known tubular type in which the oil-pot is provided with a central air-passage h, forming a central open space in the oil-pot; but as the tubular airsupply system is not utilized in this lamp when attached to the globe of a gas-lamp the burner-galleries are perforated for supplying air to the burners.
When the gas-lamp (shown in Fig. 1) is to be converted into theoil-lamp, (shown in Fig. 2,) the lower globe O is removed by withdrawing the pin of the hinge d and releasing the spring-catch D, and the burner E is unscrewed from the lower end of the gas-pipe c. The oil-lamp is then securedto the ring b of the upper globe B by means of an intermediate attaching device which is constructed as follows:
I-I is a saucer-shaped plate which is so shaped that it iits against the ring b of the upper globe B in the same manner in which the ring c of the lower globe O lits against the ring b. This plate is provided at one side with a half-hinge h', iitting into the part of the hinge d which is formed on the ring b, and engages at the opposite side with the springcatch D, so that upon applying this ICO plate to the ring b and inserting the hingepin the plate is secured to the ring b by the hinge and catch. The plate H is provided with a central opening h2, through which the lower part of the gas-pipe projects.
I represents a stop-sleeve which is applied to the gas-pipe below the plate and which is larger than this opening. This sleeve is pressed up against the plate H by a screwnut z', which is applied to the lower threaded portion of the gas-pipe. This nut and sleeve attach the plate firmly to the fixed part of the lamp, so that the plate cannot be released by merely releasing the spring-catch, in which case the oil-lamp attached to the plate would swing down with the latter. The plate H is made of saucer shape or depressed toward the middle to clear the reflectors.
K is a collar which is secured in any suitable manner to the under side of the plate H and which is provided at its lower end with an inwardly-projecting flange 7s, to which the oil-pot is removably attached by anysuitable fastening, so that by attaching the oil-pot to this collar the oil-lamp is secured in place, while by detaching the oil-pot from this collar the lamp is released.
As shown in the drawings, the collar K is secured to the plate H by screws l, which pass through depending lugs 7,', formed on the under side of the plate H, and into threaded openings formedin lugs Z2 on the collar.
The oil-pot is secured on the collar K by a spring-fastening of well-known construction, which is composed, briefly stated, of the following parts:
M represents two crescentshaped jaws, which are arranged horizontally upon the flange 7c of the collar K and pivoted to the same at their adjacent ends at m.
M' is a turn-button which is arranged between the free opposite ends of the jaws and which is journaled in the collar K and provided on the outer side of the collar with a thumb-piece. The jaws are pressed inwardly by bow-springs n, which are secured to the upper sides of the jaws and bear with their free ends against the inner side of the collar. The jaws are held down by lugs 0'L, formed on the inner side of the collar. Vhen the turn-button M stands upright, as shown in Figs. 4c and 6, the jaws project inwardly beyond the edge of the opening in the flange K and engage under the flange O at the top of the oil-pot, as shown in Fig. 3, and support the lamp. By turning the button to the position shown in dotted lines in Fig. 6 the jaws are spread apart, so as to release the oil-pot. Then the attaching-plate Il has been secu red to the upper globe B, the oil-lamp is attached to the collar of the same and removed therefrom in the same manner in which such lamps are usually attached to and removed from their supports.
Q represents two ears arranged on diametrically-opposite sides of the collar K and provided in their lower sides with upwardly-taperingnotches q,in which enter lugs p, formed on the upper part of the oil-pot. These registering lugs and ears are well known and are employed for readily placing the lamp, with its burners and chimneys, in register with the lamp-shades R. The latter are attached to the stem A when the oil-lamp is in use, preferably by means of a divided collar S, Figs. 2 and 7. The parts of this collar are connected on one side by a hinge s and at the opposite side by a pivoted thumb-nut s'.
I claim as my inventionl. The combination with a gas-lamp housing which is open at its lower end, of an attaching-plate adapted to be removably secured to the lower end of said housing and provided at its lower side with a collar and a releasable oil-pot fastening, and an oil-lamp having its oil-pot constructed to engage with said collar and to be secured thereto by said fastening, substantially as set forth.
2. The combination with a gas-lamp housing which is open at its lower end and provided at opposite sides, respectively, with a spring-catch and a half-hinge, of an attaching-plate adapted to be secured against the open lower side of said housing, having at one side a corresponding half-hinge and engaging at the opposite side with the said spring-catch, and having at its lower side a collar containing a spring-fastening, and an oil-lamp having its oil-pot constructed to engage with said collar and spring-fastening, substantially as set forth.
3. The combination with a gas-lamp housing which is open at its lower end and provided at its opposite sides, respectively, with a spring-catch and a half-hinge, and a pipe centrally arranged in said housing, of an attaching-plate adapted to be secured against the open lower end of said housing, having at one side a corresponding half-hinge and engaging at the opposite side with said springcatch and having a central opening through which the lower' portion of said pipe projects and around said opening a collar containing aspring-fastening, a releasable stop arranged on said pipe below said plate, and an oil-lamp having its oil-pot constructed to engage with said collar and spring-fastening, substantially as set forth.
