MINERS ACETYLENE-LAMR- Specification of Letters Patent.

' Patented Juiya, 1911,4

Application ined octoter 22, 1909. serial No. 524,076.

To all whom it may concern.'

Be it known that I, JAMES TAYLOR, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain ynew and useful Iniprovements in Miners Acetylene-Lamps; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to acetylene lamps and particularly to miners acetylene lamps, although the structure of the. lamp might be so modified that it could be used for variousand other purposes.

One of the objects of the present invention is to improve and simplify v,the construction of lamps of thischaracter that their cost may be reduced to a minimum and that they may be used by the most inexperienced some such manner as I provide during the.

passage of the gas to the burner; As a further provision for the prevention of clogging of the burner I cover the inner end of the burner-tip with a suitable fabric or other' suitable screeningmeans,A which, `while il will not retard the liow of gas, will insure a .uniform supply, and retard or arrest sediment and other impurities which travel with providea cap for the lower end of the water receptacle for inclosing the water-valve and protecting the same against the carbid, said cap having pertorations to allowthe water The fabric on the burner-tip may.

panying drawings, in whicli- Figure l is a vertical section view through the lamp showing the interior construction yunderstood reference is had to the accom-.

of the same; Fig. 2 ,is a perspective viewr showing the screening means between the carbid chamber and the burner; Fig. 3 isjan enlarged sectional detail showing how the. reflector is held' on the tube supporting the burner-tip; the burner-tip and the fabric on the inner end of said tip, and Fig. Il is a perspective view of the burner-tip and fabric attached thereto.

Like numerals of reference indicate corresponding parts throughout the figures. In the drawings the lamp is shown .composed of around receptacle 1, preferably much longer than it is wide and having its upper end formed with a fiaredboncave portion 2 merging into the threaded portion 3. The lower portion of the receptacle l serves as a carbid chamber 4.

Attached to and communicating with the` interior of the receptacle l or chamber t is a transverse tube 5, of suitable length, which is openboth at its inner and outer end. In the outer end of the tube 5 may be inserted a burner-tip G, which,in itself is `not unlike similar tips used on a etylene burners, but to its inneiuen'd is attached a screen 7, which may be of fabric or other material suitable for the purpose intended. Providing tlie burnertip with a screen not onlyinsures a uniform feed of the gas but retards or arrests all sediment. or other impurities which travel with the gas and which clog the burner-tip a very short space of time. As an additional Screening means, which may or' may4 notbe used, I cover the opening in the ,receptaclc l communicating with the inner end oftube 5 with a shield 8 having a plurality of perforations '9, and between the' shield porous screening material lt). The gas leaving the chamber .-Ifpasses through'tlie perforations 9 in the shield 8 and through, the screening material t0, which will retard and arrest the sediment. Should ariy ofthe finedust from the carbid pass 4through the yn'iat'erial 10, the screen fi en the burner-tip will retard or arrest such dust, thusdnsui vand wall of the lreceptacle place a suitable ing long use of the tip before clogging, and

thereby increase the eticiency of the lamp. 1l denotes a Water receptacle, the larger body portion of which is preferably coneshaped, as at 12, While the upper end corchamber 4 containing the carbid. Water 4' is introduced into the receptacle 11 through l an opening 17 in the top thereof, which is A closedby the cover or cap A18. For regulat ing the discharge ofwater from the recepjtacle 1l or'for lshutting the supply otf entirely,I provide a valve-including a -stem 19 which passes through th'freceptacle, and

l l' 0n its lower end has a gasket 20 which may be drawn up against the open end 16 of the receptacle 1l for shutting ofi'` the discharge of Water, or'moved away to regulate and control theviiowxof Water from-the recep- 'tado'. The upper end of .they stem-19 .is

vthreaded and hasengagement with a nut 21 arranged in the top yof receptacle 11,-Where 'by the. stern 19 maybe screwed down or up,

for opening or closing the valve, inthe man- I l i ner specified. @n the outer end vof the stem,

19 is the. knob or button-22, serving yas a finger hold for the operator'in regulating the valve.

' To protect ythe water-valve from the car- -bid and thereby insure its perfect operation, I provide. a ca 27 which has a .threaded portion 28, fw ereby the said cap may be screwed onto the threaded port-ion 29 of the receptacle '11.l The cap 27 is provided with a-Aplurali'ty of erfora'tions 30, both in its lower end and in its side Walls for lthe escape yof Water into the carbidchamber when the valve is open.

To the rear side of the lamp is attached .the hook 26, see Fig. 1, Afor attaching the lamp to the miners cap or other suitable support.- 4

Vhile I have herein described'what I be# lieve to be a preferred embodiment of ymy invention, yet it will be obvious that certain details thereof may be modified to some ex? tent without departing from the spirit of the inventionl and without involving more than ordinaryy mechanical skill. I do not, therefore, wish tobe limited'to the precise `de`tails described except as made the'subject threaded, a laterally `eiitending burner tubev attached tos'aid carbid receptacle near its upper end, a conical shaped' water receptacle formed with screw4 threads on its body portion in such manner as to coperatc with the sci-ewthreads at the upper end of thc carbid receptacle, the conical portion of said Water receptacle extending downwardly in the form of an inverted cone to substantially the betteln of 'said carbid'receptacle, the lower end of said conical shaped Water receptacle bein provided With screw threads, a perforate cap provided""with screw threads and adapted to engage. the threads on the lower end of said Water: rccep-l tacle, a Valve member located Withinsaid perforated cap and adapted to he seated 'against the tip of said conical water recoptacle, means for adjusting said valve. said perforated cap surrounding the valve in such manner as to prevent its contamination from hydrated carbid. In testimony whereof I affix my signature, 1n presence of two witnesses,

yJAMES TAYLOR.
