MICHAEL HICKS, OF NEW YORK, N. Y.

CAR-LAMP.

SPECIFICATION forming part of Letters Patent No, 352,243, dated November 9, 1886.

Application tiled October 23, 1885.

To all whom it may concern:

Be it known'that I, MICHAEL HICKS, a citzen of the United States, residing at the cityV of New York, in the county and State of New York, have invented certain new and useful Improvements in Lamps, ol' which the following is a specification.

My inventiony relates more particularly to plicable to lamps in steamboats and other public places, and it consists of devices for .holding the lamp-"shade and vsecuring and steadying the upper portion of the lamp-A chimney, my improvedconstruction being such as to admitI of the removal and replace disturbing eithe-r lamp-shade or lamp-burner.

I have illustrated luy-invention bythe accompanying drawings, in which Figure 1 is an elevation showing an upper section of a carlamp having connected therewith iny'improvements. Fig. 2 is likewise an elevationrepresenting the chimney-holding device thrown upward or disconnected from the chimney for the purpose of showing the springs which hold and steady the chimney when in its normal position. Fig. 3 is a detail showing one element of my invention, consisting of a clainip# of which the shade of thev lamp is supported and held injvpropenposition. Fig. 4 is anring `which encrcles the top of the chimney, and with which the springs are connected, likewise showing the spring device, constitut-` ing a further elementA of my invention, which anism by which position.

Like letters refer to like the several views. y

A indicates the supporting-frame of the lamp, secured to the roof B of the car in any suitable manner.

G indicates the lamp-shade.

D is a pipe extending through the ceiling of the car, through which the smoke and gases from the lamp escape.

E is that portion of the lamp which extends above the chimney and actsto convey upward the products of combustion in the direction of the upper pipe or ventilator, D.

said cap or ring is held in parts throughout Serial No. 180,759. (No model.)

threaded in opposite directions, and fitting, respectively, into screw threaded holes in the two ends of the spring c. The shade C is placed within the spring, and thenthe spring c' is tightened upon the shade by turning the thumb-screw d in 4the proper direction and bringing the ends of spring c toward each other. AWheni-tis desired to loosen the shade, the thumb-screw is turned in the opposite direction.

It will be observed that the' screws c /l lll C alle screw-threaded only in the spring c', passing loosely through the ring c, This is to allow the necessary slide forward and back of the ring c, incident to its adjustment 'by the bolt d.

h is the chimneysupporting ring, to which or with which the springs It lc k are connected.

m indicates a coiled spring surrounding a bolt, the same being placed within the casing o, and together constituting the means for holding the chimneysupporting ring h in po- .siticn when hinged at one side, as shown in Fig. 2. The bolt referred to is indicated by x. When this ring is in -its normal position, .the bolt shown passes within a socket, from which it is readily withdrawn by releasing the same from the pressure of the spring when .it is desired to raise or remove said chimneysupporting ring.

The special advantages of the construction constitutingmyinvention consist in the readiness withy which I'arn enabled to remove and replace the shade ofthe lamp, as well as the degree of security which is attained by holding such shade in the manner shown.

It not infrequently happens that lampshades are so loosely held in position that the motion of the car or steamboat tends to break the same, as well as to create a disagreeable rattling. MynewV constructionboth prevents rattling and guards against any liability of the breaking of the lamp-shade. The further ad-V vantages are to be found in the means shown for permitting the raising of the chimney of IOO the lamp high enough to clear the burner, so that the chimney can be removed or replaced in thelamp without removing or dis turbing either the lamp or the shade, and, still further,in the use of thehinged cap described, having in connection therewith the springs shown, which springs act to steadily support the chimney when the cap is in position and prevent any motion or rattling.

rIhe shade-holder is preferably attached by braces to the lamp-frame; but it may be entirely separated from the lamp and secured to the ceiling of the car, or otherwise sup-v ported.

The chimney-supporting ring, while preferably provided with springs le k lc, such as shown in Fig. 2, may have other suitable appliances connected therewith, which will operate within said ring for securing and steadying the upper portion of the lamp-chimney when in place. rlhis chimney-supporting ring or cap I prefer to hinge to the shadeholder, as shown in Fig. 2; but it may be fitted separately and held in place by any suitable means so as to be capable of being detached. Vhen it is desired to release the chimney from the retaining action of the springs, it is only necessary to turn back' or remove said ring in the manner indicated in Fig. 2.

The operationof the construction which I have invented is as follows: When it is desired to either place in position or remove the lamp-shade, it is only necessary to open or close the shade-supporting spring by means of the screw cl.

I am aware that it has heretofore been proposed to mount that part 0f the lamp-frame carrying the shade and furnishing a support for the chimney upon hinges, so that all that part ofthe lamp may be raised, if desired. This is a clumsy construction, since it is inconvenient to be compelled to raise the shade whenever it is desired merely to remove the chimney, and Ido not claim it. I, on the contrai-y, propose to hinge the chimney-supporting part of the frame immediately to that part which supports the shade, so that this alone need be moved when it is desired to lift the o chimney.

\Vhen it is desired to elevate the lampchimney so as to raise the same far enough to clear the burner, it is only necessary to either llift or remove the chimney-supporting ring or cap so as to release the chimney from the retaining force of the springs. rIhe number of springs required for the office indicated is preferably three; but the number may be varied. The chimney-supporting ring or cap may be turned down when hinged or placed in position when separately attached before the chimney is returned, or said chimney may be first placed in position and the supporting ring or cap either turned down or placed over the same.

Any person familiar with thc construction of lamps will readily understand the material which will be best adapted for the parts which I have described and shown.

My improved construction has the merit of cheapness,simplicity,anddurability,and,while adding materially to the qualities required in a convenient and serviceable lamp, in no way detracts from the appearance of the same, but, to the contrary, is an addition thereto in the respect last indicated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. The combination, with the support of a car-lamp, of the ring c, attached thereto, the chimney-supporting cap h, hinged to the said ring, the springs 7c k k, bolt and spring m, mounted on the cap h, substantially as described and shown.

2. The combination, with a car-lamp support, of a shade-holder attached thereto, and a chimney-supporting cap hinged to the shadeholder and provided with chimney-holding springs, substantially as described and shown.

3. The combination, in a shade-holder, of a circular spring for embracing the shade, the ends of said spring being provided with reversely screw-threaded holes,with a bolt provided at its two ends, respectively,with screwthreads of opposite inclination and adapted to engage with the threads of the holes in the spring, substantially as described and shown.
