BICYCLE-LAM P.

SPECIFICATION forming part of Letters Patent No. 562,319, dated June 16, 1896..

Application filed August 9, 1895. Serial No. 558,705. (No model.) Patented in England October 15, 1895, No. 19,300.

To aZZ whom it may concern.

Be it known that we, JAMES F. PLACE, a resident of Montclair New Jersey, and ER- NEST D. TERRY, a resident of Brooklyn,New York, citizens of the United States, have invented a new and useful Improvement in Vehicle or Bicycle Lamps, (patented in Great Britain, October 15, 1895,No.19,300,) of which the following is a specification.

Figure 1 is a longitudinal sectional view of the lamp or lantern complete when fixed to a bicycle, showing our improvements. Fig.2 is a longitudinal sectional View of our im'- proved clamp attached to the handle, showing its position when not fixed to a vehicle or bicycle. Fig. 3 is a top plan view, partly in section, of our improved air-supply perforated annular disk below the burner, which also serves as the bottom to our new closed circular and imperforated burner galleryring. Fig. iis an elevation (outside view) of part of the lamp, showing where the wickshaft comes through the lamp-body and gallery-ring in the slip-joint where joined to the oil-fountg also one of the legs with our improved circular and imperforated wind-guard flange or skirt above the same on lower part of our gallery-ring, which protectsthe horizontal air-inlet holes in the gallery bottom from wind-currents.

The object of our invention is to supply a steady volume of air to the burner without the flame being affected by outside wind-currents; to keep the lamp c001, and to furnish a handy, yet positive, mechanism for fastening the lamp to the vehicle or bicycle; and to so connect the lamp-body and oil-fount together that they can be quickly put together or disconnected.

The following is a detailed description of our improved bicycle-lamp.

Referring to the reference-marks, 1 is the lamp-body.

2 is the oil reservoir or fount.

3 is the burner.

l is the canopy-top or Smokestack.

5 is the lens.

6 is the handle, (attached to which is the clamp 17,) which is connected to the lamp body by the bracket 7.

All of the parts thus far designated may be made as shown, or of any ordinary design of lamp or lantern for outdoor use.

To the top of the oil-fount we fix a closed circular and imperforatedburner gallery-rim g 8, which incloses the burner around, the upper side ofwhich is arranged to form a closed slip-joint with the lamp-body at a point where the wick-shaft passes outside the ring, the

lower side of which ends in a flange windguard 14, and three legs 9, two of which are shown in Fig. 1, and the third one in. Fig. 4. These legs are passed through the top of the oil-fount, and riveted or clenched at 9. Within this gallery-ring 8, resting on the shoulder 10 above the imperforated flange wind-guard, we fix a perforated annular disk 11, which also forms the bottom of the gallery-ring, below the burner. This disk has a raised annular portion 12, and in and around the sides of this annular raised part are one or more circles of horizontal inlet air-holes 13 and 13', which pass in through the disk horizontally to the inside of the lamp-body, below the burner.

It will be noticed that the ring 8 has around it a circular imperforated flange skirt or wind-guard at 14: above the top of the legs 9 and below the said gallery bottom and its raised annular part. This is for the purpose of breaking any wind'currents and protecting the holes 13 and 13 from such currents.

The air passing in under the wind-guard 14 circulates around the legs 9 and over the top of the oil-reservoir 2, thus absorbing the heat of the same, and keeping the oil in the fount 2 cool. The air to supply the burner passes up into the annular raised part 12, and is drawn through the series of horizontal holes 13 and 13, and strikes the inside of the ring 8 and the outside of the burner 3 in a large number of horizontal jets, thus taking up the heat of those parts. The force of the air-currents is also much broken as there is an outward current of air against the inside of the ring 8, and an inward current of air against the burner 3 at its base, so that the air, as it takes an upward direction and rises to the burner, is delivered evenly and without sufficient force to affect the flame. It will be noticed that all air admitted below the burner is forced in between said circular flange windguard and the top of the oil-fount, as the circular gallery-ring 8 as well as said flange skirt or wind-guard is closed to the admission of air, beingboth imperforate. This is an important feature of our improvement.

To the handle 6 is attached the clamp 17. Within this clamp is a movable steel plate 21, which is held in place, and against the short end of the cam-lever 18, by the rubber cushion 20, which incloses the ordinary lampbracket 19 belonging usually to all bicycles. This cam-lever 18 has a short end 23, which is within the clamp 17, and rests against the steel plate 21. It also has a long end outside of said clamp, which is bent downwardly nearly at right angles to said short end 23. Between the short and long ends of this camlever is a horizontal fulcrum-pin 22, which is fixed to the clamp, as shown. This fulcrumpin passes through the cam-lever at a point between the short and long end, or where it passes in through the wall of the clamp, and said cam-lever turns on said fulcrum-pin as on an axis.

In Fig. 2 the cam-lever is shown in its normal position when the lamp is not fixed to the bicycle. In that position the rubber cushion presses the steel plate 21 back against the wall of the clamp and allows the bracket 19 to be easily inserted between the two folds of the rubber cushion. By pressing down the long end of the cam-lever 18, the short or cam end at 23 is raised upwardly and forces the steel plate 21 forward inwardly against the rubber cushion, and the bracket 19 is firmly gripped between the folds of the rubber cushion, as shown in Fig. 1, so that the lamp or lantern cannot be removed from the bracket until the long end of the cam-lever 18 is raised, as shown in Fig. 2.

The oil-fount, with gallery-rin g fixed thereto, as described, is made detachable from the lamp-body at a point where the wick-shaft passes outside the ring, as shown in Fig. 4. The upper side of the gallery-ring is made slightly larger in diameter than the lampbody, and in connecting to the lamp-body it slips over the lower edge and thus forms a closed slip-joint.

Having thus described our invention, what we claim as original, and desire to secure by Letters Patent, is-

1. In a bicycle-lamp, the combination of a lamp-body and a detachable. oil-fount, with an imperforated burner galleryring surrounding the burner, its upper side arranged to form a closed slip-joint with the lamp-body at a point where the wick-shaft passes outside the ring, and its lower side having a flange wind-guard, with legs connecting same to the oil-fount; a disk forming the bottom to said imperforated gallery-ring; a raised annular part in said bottom having circles of horizontal air-inlet holes, whereby the said horizontal air-inlet holes are protected from air-currents, and all air admitted below the burner is forced in between the said circular flange wind-guard and the top of the oil-fount, substantially as shown and described.

2. In a bicycle-lamp, the combination of the lamp-body, with handle attached to the same, of a clamp attached to said handle and a movable steel plate within said clamp, held in place by a rubber cushion; a cam-lever having a short end inside the clamp, and resting against said steel plate, and a long end outside said clamp bent downwardly at nearly right angles to the short end; a horizontal fulcrum-pin fixed to said clamp and passing through said cam-lever and between the ends thereof, whereby pressure exerted downwardly on the long end of said cam-lever forces the short end upwardly against said steel plate and causes said plate to move forward inwardly and grip the lamp-bracket within the rubber cushion, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 7th day of August, 1895.
