.To 'm/l m/tont fl; 111 11 (em/(www.-

lle it known that l, lanzor Fl. llu l l lNG'H )N, a citizen of the l lnited States, residing at lrlinneapolis, in the county ol lllennepin and tltati-a ol hfinncsota, have invented certain new and useful lmprovemcnts in Acetylene "llas lleneralms; and l do hereby declare the following to be a lull, clear, and exact description ol. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

lily present invention relates to acetylcnegas generators, and has l'or its object to improve thesame in theseveral partlcularshereinal'ter noted.

To the above ends the invention consists of the novel devices and combinations of devices heri-iinal'ter described, and delineiil in the claim.

The invention is illustrated in the accompanying drawings, wherein like charmzters indicate like parts throughout the several views.

l igu re 1 is a view, princi mlly in vertical section, but with some parts shown in side elevation and some parts broken a ay, illustrating my invention applied to a lamp of the type generallydesign ate/d as students lam Fi 2 is a horizontal section on the line 0i 1* 1g. 1; and lb 1g. 3 1s a detail m a vertical section, showing the nozzle ol the water-delivery tube sectioned on the same line as Fig. 1.

The numeral 1 indicates the rod ol the lam p-supporting stan d the numeral 2 the gasburner, the numeral 3 the sleeve mounted to slide on the rod 1, and the-numeral l the collar working on the rod 1 and provided with a set-screw 5, holding it wherever set. The collar 4: supports the sleeve 3, and the said sleeve is rigidly attached at two points to a vertically-disposed cylindrical case (S. The

stem of the burner 2 has an enlargement 2*, which surrounds the sleeve 3 and opens into the gascon( luits 7, formed on the l')()l1l'/UIH ol the cylii'uler 6. ward From the receiving end of 7 through the cylinder (3 at one A gastnbe 8 extends upthe conduit side thereot and terminates in acontracted nozzle a; A plug 0 in the bottom ol the cylinder (3 when removed permits the conduit 7 to be drained el" any condensed water which may have accumulated therein.

An auxiliary waterawhaml)cr ll) telescopes into the upper end of the cylindrical shell (l and is provided with a bottom 11, located aboveitslmveredge. 'llmbottom l is termed with a depending neck or sleeve-like waterpassage 12, which is normally open, but is adapted to be closed by a valve Iil when the said auxiliary waler-chambcr it) is raised vertically l'rom working position. This valve 13 has stems ll, that work telescopuially in guide-sleeves 15, secured to the top ot the chamber 10. Said valve 12-} is l'urther pro vided with a (ilepending l oot Hi, that engages with :1. lug I? on the interior ol' the shell (3 and holds the said valve open when the resm'voir or chamber 10 is in working position.

, Rigidlysecin'ed to the bottom I 1 ol' the reservoir H) by llanges 18 is a depending cylindrical gcnerating-chamber '19, which is bulged at one side, as shown at 20, to all'ord a passage tor the gas tube 8. A gas-dclivery 7 5 tube Z'l leads upward lrom the top of the gen eratiligc hamber 19 through the ater-resin voir l0 and is pr vided with a downturned branch 22, which telescopesever the upperend of the gas-tube 8 and unites with the bulged 8o portion 20 ol" the generating-chamber. 'lhe depending peripheral llange ol the reservoir 10, just below the bottom I l, is lormed with air-passages 23, which admit air into the primarywater-compartment termed within the shell 6. l t will be understood that there will be leakage ol air between the telescoping parts 01' the shell 6 and reservoir 10.

The carbid-holder is provided by a cylindrical cup 24, having a telescopica]ly-rcmovo able top 25,1'ormed with gas-escape passages 26 and with a centrallylepending sleeve 27. The cap 24 has one or more spring-lingers 24 that l'rictiomllly engage the walls of the chamber '19 to hold said cap in working posi- 5 tion against the action of gravity. A waterdistribution pipe or tube 28 opens through the bottom of the cup 2 and extends vertically upward on the axis thereol and telescopes into the sleeve 27. The lower end ol said tube 28 is open and prel'erahly is hellmouthed, as shown at 20. The bottom ot the cup 24: is shown as provided with a hub portion 30, with which the tube 28 has scre\\ 'threade l engagement. The upper end of the tube 28 terminates in nozzle having a contracted passage 3 l and a larger passage leading thereto and into which is mounted with screw-threaded engagement, a conical pointed. valve 32, having a longitudinal pas- 33. By adjustments of the valve 32 the contracted passage 31 may be opened more or less, so as to give a restricted passage ol the exact desired water-conducting capacity. Preferably a nozzle-cap 34, having perforations 35, is screwed onto the extreme upper end of the tube 2%. A perforate tube 36 is placed axially within the cup 24., surrounding the sleeve 27 and telescoping at its lower end over the hub 30. This perforate tube 36 holds the carbid 2 within the generatingchamber out of contact with the sleeve 27 and tube 28, and thus prevents the waterdelivery passages 'lrom becoming clogged by the carbid residue.

The generating-chainher or cup 24; and parts attached thereto are of course removed l rom working positions with the auxiliary water chan'iber r reservoir l and while they are removed the shell is partly tilled with water, (indicated by g in I.) This water when the removable parts are again placed in working position will rise around the generatingcliamber if), substantially as indicated in Fig 1, and it will also rise within the water-tube 2H and will overflow through the water-passages 33, 31 and 35, and lrom thence will run down the order side of said tube 28 and through the perhvrations ol the perl'orate sleeve 36 into contact with the carbidi llhenevtnr the g :-pres sure within the generating-ehambei exceeds the pressure ol' the teed-water, it. will of course drive downward the column ol water in the tube 2S and temper generation el gas. The gas gene-rat d passes first u nvard through the perforations 26.

thence tlll 'flll ljl'l. the tubes 21 and 22, thence through the contracted nozzle U" and tube 8 into the conduit 7, and lrom thence through the stem of" the burner to the burner proper. The burner Z provided with a valve 2'. The gimerating action is started by opening the valve 2" so as to reduce the s-pressure within the generating-ehamber, and the generating action is stopped by closing said valve so as to permit an increase o'l' pressure in said generatirig-chamber.

The auxiliary reservoir or chamber is of course filled while it is removed from working position and turned upside do n, so as to cause the valve 155 to open up the passage 12. When the said auxiliary reservoir is in working position, as shown in Fig. l, water will be supplied therefrom to the prin'iary water chamber whenever the water in the l- "t r is hovered so as to open the lower end of the sleeve or passage 12.

From the foregoing description and statemen made it will be understood that the devices described are capable of modification within the scope of my invention as herein. set lorth and claimed.

that I claim, and desire to secure by Letters Patent of the United States, is follows:

In a generator of the character described, the ;-,oinbination. with a shell ad apted to contain water, of an auxiliary waterreservoir fitting the upper end of said shell and com munieatii'ig therewith through its bottom, a generating cham-her secured to the bottom o'l said auxiliary reservoir and normally submerged in tl' e water cortz'tined in said shell, :1 carbid-holder reinovably held within said. generating-chamlier, a water-siu ply tube opening through the bottom ol said carbidholder from the lower portion of said shell, as-outlet tube l'ormed ol telescoping sections, one section ol' which secured to said shell and the other to said auxiliary ressuhstan ervoir and e neratingchamber, tially deieribed.
