SPECIFICATION forming part of Letters Patent No. 737,041, dated Au ust 2.5, 1903. Application filed November 19, 1902.' Serial No. 1 31,998 (No model.)
I To all whom it may concern:
Be it known that 1, CHARLES M. STnoUD, a
' citizen of the United States, residing at Minto be a full, clear, and exact description of the" invention, such as will enableothers skilled in the art to which it appertains to make and use the same. p
My present invention has for its especial object to provide an improved carbid-holder for acetylene-gas generators; and to this end it consists of the novel. construction and combination of parts hereinafter described, and defined in the claims. f
The carbid-holder herein illustrated is especially adapted for use in connection with a gas generator and burner of the character set forth and claimed in a prior joint application of Albert J. Murdock and myself, Serial No. 72,596, filed August 19, 1901, entitled Acetylene Search-Lamps.
The inventionis illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.
Figure 1 is a vertical section taken-centrally through a generator equipped with one of my improved carbid-holders. Fig. 2 is an em larged sectional view showing the lower end of the carbid-holder. Fig. 3 is a horizontalsection taken on the line 00 m of Fig. 2, the
scale of the drawings being the same as that illustrated in Fig. 1; and Fig. 4: is a bottom plan View of the carbid -holder on the same scale as shown in Figs. 1 and 3.
The numeral 1 indicates a vertically-disposed and preferably cylindrical water-tank provided in its lower end with a gas-chamber 2 and provided in its upper'end with a sleevelike passage 3, to the upper end of which, as shown,is soldered or otherwise rigidlysecured an annular nut 4:. 'As shown, water 2: may be introduced into the tank 1 through an opening which is normally partially closed by a perforated nut 5. the upper portion of the tank 1 through a vertical tube or gas-pipe 6, which extends axially through the tank 1 and opens into the cham- The gas is drawn off from her 2, from which chamber, as shown, the gas maybe drawn off through an openingor pipe 7.
' The numeral 8 indicates a large cap-nut which normally closes the opening through the annular nut 4 and has screw-threaded engagement therewith. The cap-nut 8 is rigidly secured to the upper end of a depending and preferably cylindrical support'for the car- The construction so far specifbid-holder. ically'described is shown in the prior application above identified.
Thecarbid-holder in its preferred form is cylindrical and is made up of a cylinder at '3.l1d a cup 19. The cylinder atelescopes within the cylindrical support?) and is adapted to be detachably held therein by a spring-latch 1O by an annular flange g, having several (as shown, four) small perforations or water-pas sages la. The flange g is located far below the .-top of the carbid-holder, advisedly more than half-way down, and the perforations extend nearly vertically of theholderand inward of the cylinder a, so that they may be readily cleaned or opened by an instrument of proper form in case they become clogged. Rigidly secured to the bottom of the cup I) and rising axially through the holder is an imperforate sleeve m, which when the holder is in position loosely telescopes around the gas-pipe 6.
In Fig. 1 of the drawings only a small amount of carbid is shown as placed in the carbid-holder; but it will of course be understood that the carbid-holder may'be nearly filled with carbid, allowing onlyfor the expansion of the residue. In the generating action the gas-pressure from within the carbid-holder, whenever it exceeds a predetermined pressure, forces downward or back ward the water which has risen into theannular chamber 0. On the other hand, when the gas-pressure in the carbid-holder is decreased the water is allowed to rise in the said chamber 0 and to overflow through the perforations 70 of the flange g and come directly onto the cal-bid.
The water in the chamber 0, in case the lamp is subjected to sudden jars or jolts, will splash around, but will be held by the flange g from splashing onto the carbid. At the same time the water is permitted to rise in a considerable body up to the perforations it.
To clean the perforations It, it is only necessary to pass the sharp point of a pencil or similar pointed instrument with a sweeping action around over the flange g and now and then insert the same through said perforations.
Telescoping within the upper cylindrical portion C0 of the carbid-holder and surround ing the outlet-pipe (3' is an annular perforate supplemental carbid-holder p, which rests loosely upon the carbid containing the primary holder.
The carbid-holder above described insures a steady generation of gas-that is, a generation of gas which is in proportion to the amount burned or used-and is especially adapted for use in automobile-lamps, bicyclelamps, and other lamps which are subject to jars or jolting actions which would tend to render the generation uneven.
The carbid-holder described is capable of some modification Within the scope of my invention, as herein set forth and claimed.
Vhat I claim, and desire to secure by Letters Patent of the United States, is as follows: 1. A carbid-holder having at its lower end a cup of less diameter than the said holder and connected at its upper end to the body of said holder, by a flange having restricted water passages or perforations, substantially as described.
2. A carbid-holdcr comprising the cylinder aand cup 0 which cup is connected to said cylinder a at its upper end by the perforated flange g, and is connected to said cylinder at its lower end by the flange (1 having perforations f, substantially as described.
3. In a generator, the combination with a water-tank and a removable cylindrical support 9 depending into the same, of the gasoutlet pipe 6 leading axially downward through said support 9, and the carbid-holder comprising the cylinder a telescopin within said support 9, and the cup 1) of less diameter than said cylinder a, rigidly connected to said cylinder by an outturned flange g having perforations it, said cup Z) having also the sleeve m telescoping around the pipe 6, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES M. STROUD.
