LAM P-eu RNR ATTACHMENT.

SPECIFICATION forming part of Letters Patent N o. 748,889, dated January 5, 1904.

Application iled May 15. 1908.

T a/ZZ whom t may concern:

Be it known that we,WATsoN B.- STOCKMAN and JOHN F. FRIEL, citizens of the United States, residing at Chester, in the county of Delaware and State of Pen nsylvania,havein vented certain new and useful Improvements in Lamp-Burner Attachments, of which the following Ais a specification.

This invention provides a simple attachment for the ordinary form of oil-lamp burners for extinguishing the darne after the wick has been lowered or in case of accident to instantly extinguish the flame though the wick be turned up to its fullest extent.

The attachment is adapted for application to the type of burners aforesaid which are in use or may be applied to them when placed upon the market.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible lof modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the burner, parts broken away. Fig. 2 is a vertical sectional view showing more clearly the operation between the presser-bar and the extinguishing-sleeve which surrounds the wicktube. Fig. 3 is a perspective View of' the presser-bar removed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. l

The attachment contemplates the provision of a hollow wick-shaft 1, which is applied to the burner 2 as usual and which is provided with the spur-wheels 3, by which the wick is operated. The burner-cap 4 also is illustrated, and the finger-piece 5 of the wickraisi'ng shaft 1 will also be seen to be of the type commonly employed for this purpose. The hollow wick-receivingshaft 1 receives a reciprocatory bar 6, which constitutes what will be termed a spring-retraction presserbar. The presser-bar is provided 'at its in- Serial No. 157.296. (No model.)

I ner end with'a bent portion or inclined engaging part 7, which coperates with the sleeve 8 to extinguish the flame when this becomes necessary. The sleeve 8 is preferably of tubular form, though any other suitable means of analogous character may be substituted for the same within the sphere of our invention. The presser-bar 6 is provided at its outer end with a finger-piece 9, by which same is manipulated. Between the fingerpiece9 and the finger-piece 5 of the shaft 1 is interposed a coil-spring 10, which is disposed about the bar-6 and serves to hold the presser-bar normally in an outmost position. The finger-piece 9 of the presser-bar is preferably revoluble, so that should same be seized by mistake for the purpose of raising or lowering the wick no damage will be suffered by the attachment. Projected from the lower portion of the sleeve 8 is an extension 11, which extension covers a lateral lug 12. This lug is inclined and cooperates with the inclined portion 7 of the presser-bar to raise the sleeveB when it is desired to extinguished the flame. The presserbar 6 is guided in its movement by a pair of lugs 13, disposed upon the base of the burner, which lugs engage the presser-bar upon either side of the upturned end portion thereof and serve to prevent any lateral movement of the inclined end 7, so that this inclined end is assured a movement which will also cause cooperation with the lug 12, projected from the extension 11 of the extinguisher-sleeve. This is deemed of some importance to the practical embodiment of the invention.

In the operation of the attachment to extinguish the dame, the presser-bar being in its outermost position, it is but necessary to exert a pressure upon the finger-piece 9 to force the presser-bar 6 inward. This causes the inclined end portion of the said bar to ride into engagement with the lug 12, this movement causing subsequent vertical'movement of the extinguishing-sleeve 8. Removal of the pressure upon the finger-piece 9 permits same to resume its normal position under the induence of the spring 10 in a manner which will be readily apparent.

The attachment involves a decided simplicity relative to the number of parts used, and consequently the cost of manufacture is reduced to the smallest degree consistent with proper material and other considerations.

Having thus described the invention, What is claimed as new is l. In an attachment of the class described, the combination with a lamp-burner, of a wick-tube, a spring-retracted presser-bar disposed for reciprocal movement upon the bu rner, an inclined engaging portion disposed upon the presser-bar, extinguishing means disposed adjacent the wick-tube aforesaid, and means extended from the aforesaid eX- tinguishing means adapted for coperation with the inclined portion upon the presser-bar whereby the Iiame may be extinguished.

2. In an attachment of the classdescribed, the combination with a burner, of a hollow Wick-raising shaft disposed thereon, a springretracted presser-bar disposed for reciprocal movement within the wick-raising shaft, an inclined engaging part disposed upon the presser-bar, guide means cooperating with the presser-bar to direct the movement of the aforesaid inclined portion, and an extinguishing-sleeve disposed adjacent the Wick-tube and coperating with the inclined portion of the presser-bar.

3. In an attachment for burners and the like, the combination with a sleeve disposed adjacent the wick-tube, a hollow wick-raising shaft, a spring-retracted presser-bar disposed within the shaft for reciprocal movement, an extension projected from theextinguishing-sleeve aforesaid, and an inclined engaging part provided upon the presser-bar for engagement with the aforesaid extension and for actuation of the sleeve by such engagement.

4. In an attachment for burners and the like, the combination with a wick-tube, an extinguishing-sleeve disposed about the said tube having a lug projected therefrom, a hollow wick-raising shaft, a spring-retracted presser-bar disposed for reciprocal movement within the said shaft and having its inner end bent upward to form an inclined engaging portion for coperation with the lug projected from the extinguishing-sleeve.

In testimony whereof we affix our signatures in presence of two witnesses.
