CYCLE-LAMP,

SPECIFICATION forming part of Letters Patent No. 480,210, dated August 2, 1892.

Application filed September l, 1890. Serial No. 363,616. (No model.)

To all whom, it may concern..-

Be it known that I, ALBERT H. OVERMAN, oi' Springfield, in the county of Hampden and State of Massachusetts, have invented new Improvements in Cycie-Lamps and Suspension Devices Therefor; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, and represent, in-

Figure l, a rear view in perspective of a lamp and suspension device constructed in accordance with my invention and shown as applied to a steering-head, which may be that of a Safety bicycle or of a tricycle; Fig. 2, a similar front View of the lamp and suspension device with the bowed glass removed. Fig. 3 is an inside perspective view of the lamp, which is therein cut in two on the line a b of Fig. 2. Fig. 4 is a View ot' the lamp in transverse section on line c d of Fig. 2. Fig. 5 is a similar view showing one way how the external contour of the lamp may be modified. Fig. 6 is a rear view in perspective showing the lamp-fount detached and adapted to direct draft instead of indirect draft, as is provided for in the lamp shown by the preceding figures. Fig. 7 is a view in tranverse section corresponding to Figs. 4 and 5 and showing a lamp adapted to direct draft and having the back of its body portion shaped to form its reflector. Fig. S is a detached view in transverse section of the clamp of the suspension device shown by Figs. 1 and 2.

My invention relates to an improvement in cycle-lamps and suspension devices therefor, the object being to produce a lamp of simple, compact, and cheap construction adapted to carry, in proportion to its size, a large quantity of oil and to keep the same at a low and uniform temperature and so insure a steady combustion and good light.

A further object of the invention is to provide a simple suspension device which will securely support the lamp and cushion it against the vibration of the machine.

TWith these ends in view my invention consists in a cycle-lamp and a suspension device rfount has greater capacity in proportion to the size of the lamp than it can have in construct-ions in which it is made independent of the lamp -body and inserted thereinto. The fount is also directly exposed to the air and is therefore kept cool and a steady and uniform combustion secured, whereas inclosed founts gradually heat and cause an.

unequal burning of the flame.

By making the hood C of the same transverse section as the fount A and the combustion-chamber B, I secure not only an ample and steady draft, but also a construction especially well adapted to the use for which the lamp is designed, as it has the strength and stability pertaining to simple integral structures, affords the least opportunity to catch and hold dirt, will not rattle, reduces the wind-resistance to the minimum, and by its compactness and its smoothness escapes as far as maybe the heavy Wear and mishaps of cycle-riding. The said fountis provided with a illing-capD and burner E of any approved construction, the latter being provided with an ordinary horizontal wick-adj usting spindle F, which projects outward through a horizontal slot F', formed in one of the side walls of the combustion-chamberB, before mentioned.

Preferably the front and side edges of the between the forward edges of the fount and` `nood is inclosed by a single bowed plate of IOO glass H, curved to con form to the general form of the lamp and mounted in a light metal frame Il', adapted to be hinged at one edge to the said eombustion-chamber B, as at H2, and at the other' edge to be fastened thereto, as at H3. 4This bowed glass takes the place of the lens and the two side lights ordinarily employed in cycle-lamps.

The reector I, which is of ordinary construction, is set into an upright partition J, mounted in the rear portion of the combustion-chamber and located in the plane of the edges of the reliector which it is cut away to receive, its upper edge meeting the lower face of the horizontal centrally-perforated flat diaphragm K, which forms the upper wall of the said combustion-chamber, its side edges joining the side walls of the said chamber and its lower edges being terminated above the top of the fount, so as to form an opening under them and under the reflector for the draft of air which iiows down behind the said partition and refiector, which, together with the rear wall of the chamber, form a flue for it, the air being taken in through fine perforations B', formed in the said rear wall at a point about in line with the upper edges of the reflector and partition. A draft-guard M, secured to the upper face of the diaphragm K, near the ends thereof, arches over thecentral perforation K', formed therein, and eX- tends in line with the length of the hood and hence at a right angle to the curve thereof. It is made enough narrower in width and enough lower in its arch than the hood to permit the draft of the lamp to draw over its edges and top, and to increase the draft openings M M are formed in its edges virtually in line with the openings C C formed in the ends of the hood. Under the provisions of the above-described construction the draft will enter the perforations B and flow down back of the partition J and the reflector I, issuing to the flame under the edges thereof. The draft will then be upward through the combustionchamber L, thence through the perforation K of the diaphragm K into the hood, where it will be deflected by the draftguard, and finally issue through the openings C C at the ends of the hood.

If desired to employ a direct instead of an indirect draft, two upright tubes N N, open at both ends, may be set into the fount, as shown by Fig. G of the drawings, and take air at their lower ends, which open into a chamber N', formed by a false bottom N2, of sheet metal, extending below the bottom of the oilfount.

Fig. 4 is designed to show the general form in transverse section of the lamp shown in the preceding figures. This form may, however, be varied to have square corners, or its corners may be made still rounder, as shown by Fig. 5. In case the lamp is adapted toindirectddraft, the back of its body portion may be shaped to itself form the reflector, as shown by Ns in Fig. 7, and the back tine dispensed with, or a reflectormight be attached directly to the backr of the body portion of the lamp, which in' the said figure is rounder in transverse section than any of the lamps shown by the preceding figures.

As shown in Figs. l and 2, the suspension device is composed of two arms O O, flat in transverse section, bowed longitudinally and outwardly, and respectively attached midway of their ends to the inner face of the iiexible shell O of a clamp having a rubber lining O2 and abindingscrew O3 and adapted to receive a bent loop O4, having its ends secured to a clip O5, embracing the steering-head OU, which may be that of a tricycle or of a Safety bicycle. Four spiral springs IJ connect the sides of the lamp above and below the center thereof with the ends of the arms O, which spread considerably more than the Width of the lamp, so that the same is hung between them and cushioned against shocks from any quarter, the springs being opposed in tensiont The corresponding arms O7 O7 (shown in section by Fig. 9 of the drawings) are made of wire rods and are round in cross-section. If desired, the arms, whatever their construction and shape may be, may be made sufficiently resilient to supplement thecushioning action of the spiral springs.

As shown by Fig. 7 of the drawings, the suspension device consists of four parallel spring-rods Q Q Q Q, arranged in two pairs and having their inner ends mounted in a clamp Q', which may be of any approved construction. Each of these rods is coiled midway of its length and bent at its outer end to form a hook, the hooks of the respective pairs of rods being inserted into the opposite ends of loops Q2 Q2, one of which is attached to the top and the other to the bottom of the lamp, which is thus suspended between four springs arranged in two pairs opposed in tension.

It will be apparent from the foregoing that in carrying out my invention some changes from the exact forms herein shown and described may be made. I would therefore have it understood that I do not limit myself to such forms, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A cycle-lamp having parallel sides and containing an exposed fount, a combustionchamber, and a hood, all forming divisions of the same body portion, a reiiector located in the said chamber, means for supplying a draft of air thereto, a horizontal diaphragm separating the combustion-chamber from the hood, and a bowed glass constructed to extend across the front and partially around the sides of the combustion-chamber, which is thereto appropriately formed, substantially as set forth.
