LAMP.

Specication of Letters Patent.

Patented May i4, 1918.

To all 'whom t ma concern:

Be it known t at I, CHARLES RYDER, a citizen of the United States, and ay resident of the city of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forining part of this specification.

My invention rela-tes to oil lamps, of the type wherein the font is detachable from the lamp body and is locked in place against Such lamps are usually employed as tail lights and side lights in carriages and automobiles, as in these uses the necessity of the removable font, capable of being securely locked in place, is iinportant.

It is the object of my invention to provide an oil font attachment for such lamps, which is fool-proof to a high degree such that when installed, the failure ot' the op-y erator to securely lock the attachment will not result in the dropping oli of the font.

This object and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawing,

Figure l is a Side elevation of the lamp complete. f

Fig. 2 is a detail side elevation of the lower end of the lamp body partly broken away to show the -mounting channel for the locking ring and the inclined bearing edges for the pins on the font.

Fig. 8 is a horizontal section taken through the lamp body just above the locking ring, showing the same in unlocked position with the font removed.

Fig. 4c is a sectional view of the lamp taken horizontally through the said locking ring, with the same in locking position, with the font in place.

Fig. 5 is a detail top plan view of the locking ring partly broken away.

Fig. 6 is a perspective view of the part shown in Fig. 5.

Fig. 7 is a perspective view of the lamp font.

The lamp body l is provided with the depending cylindrical portion or socket 2, into which the font is to be thrust and in which the locking of the fontin place is to be accomplished. The lamp font has an oil pot .portion 3, a cylindrical portion 4 which fits into the depending cylindrical portion or socket of the lamp body, the wick tube or burner 5 and the wick shaft 6.

On the cylindrical portion a of the font are a plurality of pins 7 (three by preference), and the wick shaft is alined with one of the pins when the font is to be inserted into the lamp body.

The edges of the body at thelower end of the socket portion 2 are turned up inwardly so as to form a channel 8. The edges are cut at 9, 9, to form clearances for the pins 7. The metal so intumed is cut away to form sloping walls l0, l0, so that when the font is inserted with the pins entering in the cuts at 9, 9, the turning of the font will bring the pins up along the sloping walls, and thus elevate the font in the socket so that it abuts irmly against the base of the same.y

Set in the inside of the socket portion of the lamp body is a semicircular plate l1, which seats and slides in the channel 8. This plate has a vertical cut 12 which receives one of the pins on the font and also the wick shaft when the font is inserted. It has also a screw 13 set into it, on which screw is mounted the clamp nut 14.

The socket is cut with a vertical slot l5 to permit the passage of the wick shaft, and a transverse slot 16 communicating therewith, to give a clearance for the wick shaft so as to permit of the font being turned withinv the socket. It can thus be seen that when the wick shaft is thrust up into the slot in the socket and also the registering slot or cut 12 in the plate ll, the font can then be turned part way around thereby moving the plate l1, sliding the wick shaft to the end of the branch slot 16, and drawing the font tightly up against the socket base, by means ot the pins, as heretofore described. 1

The soolet is provided with a horizontal slot 17 for the passage ol' the screw 13 on the sliding plate, and to tighten the sliding plate in desired position the Clamping nut lli: is turned down on the screw against the outside socket Wall.

As so far described, the security oli the device is dependent upon the Care of th@ operator in inserting and looking the font in place. lt he should not turn it sutlioiently, or should leave the nut llt loose, the font will drop out and become lost it the use is onan automobile, particularly when used as a ctail light which is not Within the range. of the drivers vision.

A spring device is therefore provided With Tvhieh to insure the proper mounting of the font, and hold the 'tout against talling out Whether the Clamping seresv is turned np or not. i

The semioironlar sliding plate is out with a slot 18 and secured aga'nst the basl; or inside surface oi the plate is a spring 19. The screw 13 may be used for securing this spring in place, thereby avoiding a multiplioity ot parts and operations. rllie spring has a nose Q0 bent in it which extends through the slot 1S. rShe cylindrical socket portion ot the lamp body is ont With tivo slots 2l and 2Q, to allow the spring nose to protrude.

When the sliding plate is in looking position with regard to the lont. the spring nose willv extend out of the slot 2l. llhen the said plate is in releasing position, the nose Will be in the slot This latter position of the springy nose is to permit the lont to be withdrawn from the socket, since if the spring nose were not given this clearance the Close itting portion of the font 'would not be removable from the socket.

When the operator inserts the font,V he turns the font in his hand to look it. QW- ing to the Configuration ot the nose on the spring, `it will snap out of the slot The font Will then more the sliding plate until the nose snaps into the slot 2l. This will stop the nioyementI of the font and will indicate that the Jront is locked in place.

The operator should then tighten up on the clamp nut. H- he should tail to do this, however, the plate would be held by the spring. The nut need not be used with the A rest of the combination unless so desired,

but it adds securitye and also prevents the device from rattling.

The spring takes entire Care ot the sliding plate and thus looks the 'tout in position. The snapping oi' the spring into the two slots inthe soelret portion of the body indicates resales bot-h open and shut position to the operator, which is considerable oit a. convenience.

The device is simple and tree l'rom the considerable ditlioulties of adjusting and assembling which are to be found in the lamps of the prior art with which l am familiar.

Having thus described my invention, what l claim as ne v and desire to secure by liete trs Patent, is
