SPECIFICATION forming part of Letters Patent No. 554,089, dated February 4, 1896. Application filed December 3, 1895. Serial No. 570,946. (No model.)

To aZZ whom it may concern.-

Be it known that I, PATRICK HENRY QUINN, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Electric Carriage-Lamps,

of which the following is a specification,

This invention has reference to an improved electric-light attachment to the ordinary can- IO dle-holders of carriage-lamps, so that in place of candle-light electric light can be readily used, said attachment being so arranged that it can be readily removed in case of the breaking of the lamp or its filament, or in case of I 5 the giving out of the battery, while the candle can be then used in the ordinary manner.

The invention consists of an electric-light attachment for carriage-lamps, which is composed of an insulating-socket provided with retaining-springs inserted into the cup or cone of the candle-holder of a carriage-lamp, a spring-cushioned lamp-holder supported on said socket,-means for locking said attachment to the cone or cup of the candle-holder,

and an electric lamp inserted into the lampholder and connected by conducting-wires with the source of electricity, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation showing my improved electric-lamp attachment to carriagelamps. Fig. 2 is a side elevation of the same on a larger scale and shown as detached from 3 5 the carriage-lamp. Fig. 3 is a vertical central section of the lamp attachment; and Fig. 4 is a cross-section of the same on line 4 4, Fig. 2.

Similar letters of reference indicate corre- 0 sponding parts.

Referring to the drawings, A represents the cup or cone of the ordinary candle-holderfor carriage-lamps 0, into the guide-tube A of which my improved lighting attachment is inserted. This attachment is formed with a socket B of insulating material, to the lower end of which are apppied retaining-springs "b b, that bind on the interior guide-tube A of the cone A, so as to be retained in position The socket is made hollow, so

as to receive a suitable spring d, which forms a cushion for the lamp-holder D, mounted thereon, so that the lamp-holder with the incandescent lamp E can have certain vibrations, or an up-and-down motion, so that the 5 incandescent lamp in the holder is protected against jostling of the carriage. To diametricallyopposite sides of the socket B are applied locking-springs B, which extend through the recesses of the flanged top part D of the holder, said springs being bent at their upper ends so as 'to form shoulders I), that engage the upper edge of the cup or cone A of the candle-holder, and in connection with the bottom springs thereby retain the attachment firmly in position in the cone A.

To the flanged top D of the lamp-holder D are attached the binding-posts of the conducting-wires f j, which lead to a storage-battery placed under the drivers seat or to any suitable source of electricity. A small incandescent lamp, giving'a light corresponding to that of the candle, is screwed into the holder, and can be readily detached therefrom when it is necessay to replace the same by a new lamp. The attachment can be readily removed from the cone of the candle-holder in case of breakage of the lamp or its filament,

or of lack of current, or any other accident or interruption of the current, so that the candle can be lighted and used in the ordinary manner in carriage-lamps.

The electric-light attachment permits the use of the present carriage-lamps, without changing the same, by simply inserting the attachment in the cone of the candle-holder of each lamp, so that thereby electric-lighted carriages and other vehicles are obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An electric-light attachment for carriage-lamps, consisting of a socket, means for retaining said socket in the cup or cone of the candle-holder of the lamp, a spring-oush- 5 ioned lamp-holder supported on said socket, an incandescent lamp inserted into thelampholder, and conducting-wires connecting said lamp with the source of electricity, substantially as set forth.

2. An electric -light attachment for carriage-lamps, consisting of a socket provided with bottom springs, for retaining the socket in the cup or cone of the candle-h0lder of the lamp, a spring-eushioned lamp-holder supported 011 said socket, means for locking the socket to the cup or cone of the candle-holder, an incandescent lamp inserted in the lampholder, and provided with the usual metallic contacts, and conducting-wires attached to the la1np-l1older and connected with the con- I o taets of the same, said conducting-Wires being adapted to communicate with a suitable source of eleetrietity, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres- I 5 enee of two subscribing Witnesses.
