To @ZZ whom mayozwew/a-z z.

I Be it known that I, JOHN H. WAITE, acitizen of the United States,residing`at YRock Falls, in the county` of :Whiteside and State Vof Illinois, haveinvented 'certain new ,and

useful Improvementsin Acetylene-Gas Genj erators; and I do declare the followingto be.

a full, clear, and `exact description of the `invention, such as will Tenable'others skilled inthe art to which `it appertains to make` and use the same, reference being had to the aol erators, and pertains specially to a novel construction whereby the manufacture of the gas within the gas-chamber is automatically regulated and provision made for `renewing the Acarbid and removing the limeresulting from the chemical action, while the gas-chamber isl filled without reducing the pressure of the f gas therein.

In the drawings, Figure 1 is a central Vertical section of my device. Fig. 2 is a plan view of the `cover thereof. Fig.'3 is a central vertical section of my invention in modified form.

Similar figures refer throughout the drawings. y

1 is a water-tank,win which the gas-holder 2 has vertical telescopic movement.

3 is an annular casting secured to the generator by means of the ilange 4, between which and the generator.. is the gasket 5, to

prevent leakage of the gas between such parts.

The casting 3 serves as a support or seat `ii'or `the cover and is projected downward through 1 a circular opening 6 in the top of the generathe collar 7 and the upper part 10 loosely The cylinder 8 pro?` tor, forming the collar 7 8 is a cylinder formed of two parts 9 and 10, the lower part 9 being rigidly secured to seated `uponthe part 9. jects downward the same distance as the walls of the gas-holder, thelower end thereof being` always below` the `water-line, (represented by the dotted line 00,) so as to prevent gas entering such cylinder from below.

11 represents a packing between the cylinto similar parts` I der 8 and collar 7, extending below the j unction ofthe two parts of said cylinder.

12 12 are apertures extending through the movable portion 10 of the cylinder. 13 13 are v"similar and corresponding openings through the collar 7T and the packing between it and the cylinder.

14` indicates a cover seated upon the support 3 and separated therefrom by an annular gasket 15. The casting 3 is further `provided `with two supports 16, having outwardlyformed lugs 17 and inwardly-formed lugs 18, which latter lugs project over the cover and prevent its removal. `The cover 14 is secured ftightlyagainst its seat4 by means of an ordinary clamp-and-screw device 19, which engages the lugs 17. The cover is further provided with recesses 20, which permit a removal of such cover `when they coincide in line and position with the lugs 18.

21 21 are handles on the upper side of the coverwhich assist in turning or lifting the same.

On the lower face of the cover 14 are one ,or more `lugs 22, which engage corresponding recesses 23 in the movable portion 10 of the cylinder 8.` j

24 is a short pipe provided with a stop-cock to permit the escape of air from the cylinder when the gas is iirst being generated therein. A similar pipe 25 permits a similar escape of air from the gas-holden It will be readily apparent that when the cover 14 is in position a rotary movement of it will give to the movable portion 10 of the cylinder a similar movement and the apertures 12 therein be made to correspond with the apertures 13 in the collar 7 or not, as desired. The arrangement of the lugs 18 and recesses 2O is suchthat when they exactly coincide, as shown in Fig. 2, the apertures 12 and 13 do not coincide and all communication between the cylinder 8 and gas-holder 2 is completely cut off, so that the `coverean be Vremoved. When the cover is replacedand "turned a certain distance, such apertures again correspond and communicationfisreestablished between the two compartments. To preclude the dangerof the coverandicylinder being turned too far,so as to reclose such openings, l provide projections or stops 26 on the cover 14, which strike against .thefs'up portsI 16 and'prevent further movement of the cover or movable part of the cylinder.

Within the cylinder S is the carbid-cylinder 27, having lugs 2S, supporting the annular rim 29, to which is secured a hemispherical basket 30, constructed of open'wirework.

3l is a bar secured to the rim 29 by means of braces 32 32, from which bar 31 is suspended the cylindrical refuse-pan 33 by means of hooks 34 34.

The rim 29 is recessed similarly to the cover 14, so `that when lsuoli rim is turned until ythe recesses 4coincide with the lugs 28 the basket can be removed from the lower end of the cylinder 27.

f' On the lower face of the cover 14-is the ring 35, tofwhich is hooked the 'rod 3G. Secured to the top of the cylinder 27 is a cross-piece 37, having an aperture 38, in which the rod 3G ffhas vcrticalplay, sucli aperture being slightly Ulargerthan the diameter of said rod, which is threaded at this point and provided with vburs 39 and 40.

' 40 is so situated on the rod 3G as to be in con- Atact withthe cross-piece 37 when the gas- "liolder is atfits lowest'point, when the gas is risethe cylinder 27' will rise immediately with the gas-holder; but if the bur is placed at a lowerV point on the `rod 3G as the gas-holder risessuch rod will be drawn up through the 'aperture 3S until the bur 40 comes in contact with-the cross-piece 37, and the cylinder 27 'will not beelevated until such contact takes place. By this construction the length of time ofl thev contact of the water and carbid can be regulated or gaged and ythe manufacturing process prolonged or shortened, as desired.

` It is preferable to expose but a small part of the carbid to the water at'one timev and the-'hemispherical shape of the basket assists greatly in accomplishing this, as a` very'small area or larger Yone may be' exposed, as desired, but in receptacleshaving at'bottonis this cannot be regulated.

`By'locating the'basket 30 above the bottom of the cylinder 27 the gas generated cannot passoutward'and up between the cylinders S and 27, but mustpass up through the carbid inthe carbid-cylinder, keeping the same free from steam.

41 is -a pipe by means of 'which thel gas can be conveyed from the gas-holder to other -gasoine'te1's, ifdesired, or the gas-holder can be provided'with ya pipe 42 and the gas used directly` therefrom.

In operation the cylinder 27 is filled with calcic carbidand suspended in the cylinder S, softliatftlie carbid comes in contact with lthewater The cover is secured in-position "and clamped down. As the gas forms it passes Aupward through the cylinder 8,' through the ;'a'pertures 12 andv 13, into the'gas-holder 2.'

The Voperation is automatic, as in most machines of this class, the manufacture ofthe gas It is evident that if the burgenerated and the'gas-holder 2 commences to ceasing as the reservoir rises and commencing again as it falls, subject, however, in my invention to the vertical adjustability of the carbid-cylinder. The residuum or lime resulting from the chemical operation falls into the pan 33, designed therefor.

When it is desired to renew the carbid or empty the'pan 33, the clamp 19 is iirst removed aiid the cover turned to a position where it can be removed.4 The same operation cut-s oi'lz the communication between the cylinder and gas-holder and confines the gas in the latter. As the pressure of the gas in the cylinder is-the sameas that in the gasholder the small amount of gas therein can be let out through the pipe 24 just before the cover is released. The cover is then removed and the cylinder 27 and pan drawn out, when the'pan can ybe ufnhooked and dumped and the cyliii'derreiilled If necessary for repairs or otherwise,` after the pan is detached thebasket 30 can be removed from' below, using the bar 3l as ahandle. yAfter all'neceslsary matters are'attended t'othe parts are again placed in position, the cover replaced,

communication with the gas-hold er restored,

and the? operation proceeds as before. As is customaryv in machines of this nature the pressurey of the gas may be increased by weighting the gas-holder.

Fig. 3 represents a modified construction of my machine, wherein the cylinder S is'formed in one piece, the apertures 12 communicating immediately with lthe gas-holder 2. At the upper end the cylinder is provided with a llange 43, resting on the annular rim 44 on the support 45. 46 is al collarrigidly secured to 7the cylinder 8 and ,havingV a flange 47, upon which are two supports 1G and lugs 18 for securing the cover, which is substantially the same as in` Figs. 1 and 2, except that it has no lugs 22 or stop 2G. The cover is clamped down, as in Fig. 1, bya'clamp 19 engaging'lugs 17. In operation, in order to cut off the communication between the cylinder and gasholder, the clamp 19 is first removed and the cover raised vertically, drawing fwith it the collar 46and cylinder 8, attached thereto, until thel Vapertures 12 are covered by packing in the annular recess 48 in the support 45, conliningV the gas in the gas-holder'andpermit- 4ting the cover to be' removed.

In Fig. 3v the refuse-pan 33 is niadedeeper and rests upon :lugs 4901i the inner face of vthe cylinder 8, the rim 29 of the basket resting upon the upper edgex thereof.v 50 50 are perforations in thefpan 33, which permit the water to enter such Lpanand come in contact with thelbasket 30 and'carbid therein. In this construction the cylinder 3 serves also as a receptacle for the carbid, -which can be placed thereinto any desiredheight. To clean the pan 33,- the basket 30 is removed when `empty andthe residuuiii in thefpan taken out with a long-handled scoop or by other suitable means.

The two constructions ol `carbid-holders 573,938 y i t can be used interchangeably with either oonstruction of the cylinder S.

W'hat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. In an automatic gas-generator the co1nbination of the cylinder 8, formed of the stationary part 9 and movable part 10; the collar 7 embracing such cylinder; apertures penetrating such movable part 10 and collar 7; and the cover 14 engaging the movable portion of the cylinder S, substantially as shown and set forth. t

2. In a gas-generator the combination of the cylinder 8, composed of the sections 9 and 10; apertures 12 in the movable section 10; andV the cover 1i provided with handles 21, lugs 22, recesses 20, and stops 26, with the supports 16, having lugs 18; the relative position of the recesses 20, lugs 1S, supports 16,` and stops 2G being such, when the cover 14- is in engagement with the movable part of the cylinder 8, as to open the communication between the cylinder 8 and gas-holder 2 when the stops 26 are in contact With the supports 16; and cut oft such communication when the recesses 2O coincide with the lugs 1S, substantially as set forth.

In testimony whereof I afiix my signature in presence of two Witnesses.
