ACETYLENE-GAS GENERATOR.
SPECIFICATION forming part of Letters Patent No. 675,376, datedJ'une 4, 1901.
Application filed February 18, 1901. Serial No. 47.756. (No model.)
To all whom it may concern:
Be it known that I, AUGUSTINE DAVIS, a citizen of the United Statesof America, and a resident of the city of Chicago, county of Cook,
and State of Illinois, have invented certainnew and useful Improvements in Acetylene- Gas Generators, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a vertical sectional View of an apparatus embodying my invention, taken on the line 1 1 of Fig. 2; Fig. 2, a plan view of the apparatus complete; Fig. 3, a horizontal section onthe line 3 3 on Fig. 1; Fig. 4, a detail vertical section on the line 4 4: of Fig. 2; Fig. 5, a detail perspective of the cams for releasing the latch or hook from the feed-rod; Fig. 6, a detail perspective of the feed-shoe; Figs. 7 and 8, detail views of the feeding devices; Fig. 9, a detail perspective showing the lugs h for locking the sealing cap orcylinder over the carbid-holder, and Fig. 10 a detail view of minor parts hereinafter described.
The main object of this invention is to provide a feeding mechanism which will feed carbid without clogging and in quantities commensurate with the consumption of gas and which also will force the carbid in small but sufficient charges into the water in the generatingchamber in such manner as not to depend on gravity alone for delivery, as more fully hereinafter set forth.
Referring to the annexed drawings by letters, A designates a cylindrical main casing, closed at its bottom by means of a generating water-chamber B, whose conical bottom is connected to a discharge-spout b, extending laterally out through the main casing; C, a bell or receiver of any suitable form, sealed in Water contained in the main casing and adapted to rise as it fills with gas through tube 0, connected to the water-chamber and extending up through the sealing liquid; D, a filter connected to the gas-space of the bell and to the outlet-pipe in a suitable manner,
and E a stationary cylindrical guide for the bell. The inlet-pipe of the filter is designated by the letter D, the outlet-pipe by D and the drip or drainage pipe by D which latter is sealed in the drainage-tank D Connecting the drainage-tank to the water-chamber B is an overflow-pipe E. Rising from the bell C is a tube C, whose upper end is closed and whose lower end depends 7 into and is sealed in the water in the main tank, and extending up through the top of the water-chamber and through the liquid in the bell and into this tube C is a supplemental outletpipe C The object of this is to permit gas to escape out through pipe C in case the bell reaches a predetermined dangerous. limit. All the foregoing parts are constructed in any suitable manner and need not be more fully described in this specification.
\Vithin the main casing and aflixed at its lower end to the top of the generating-chamber B and opening thereinto is a cylindrical casing F, whose upper open end is closed by. a carbid-holder G, which is cylindrical in shape and depends into casing F, being supported within the same by a lateral annular flange 9, formed on its upper end and resting upon the upper edge of casing'F and completely closing the same. The carbid-receptacle is held in place and sealed by means of a cylindrical cap H, fitting down over casing F and having its lower open end sealed in the liquid in the main tank, the upper closed end of this cylindrical cap resting directly upon the top of the carbid-holder. This sealing cap or hell is held removably in place by means of a pair 'of lugs h, affixed, respectivel y, to the interiorof the main casing and the exterior of the sealing-cap and overlapping and held removably together by a removable pin adapted to be dropped into the holes h in both lugs, the lug on the sealing cap being underneath the other lug.
To prevent the gate of the discharge-spout 79 being opened during the operation of the machine, I journal a vertical rock-shaft I upon the exterior of the main casing and provide its upper end with a lateral arm 1', which is formed into a ring 1" at its free end, which ring fits over a cylindrical enlargement t" on the sealing-bell H, and its lower end with a lateral arm '6 which engages over and locks the gate closed. To remove the carbid-holder, it is necessary to first raise the rock-shaft sufficiently to disengage ring 2" from the enlarge ment t'" and swing it to one side from over the sealing-cylinder, which action simultaneously swings arm '5 from over the gate and permits it to be opened by an attendant. To removably lock ring upon the neck or projection i", a pin is passed laterally through an opening in a lug i rising 'from the same.
The carbid-holder terminates in a depend ing spout g, from which is suspended a feedshoe J, consisting of a pair of side plates or arms 3', embracing the spout and pivoted thereto at their upper ends and connected at their lower ends by afeed-plate j, which normally lies directly under the spout and closes the same, the upper surface of this feed-plate being curved on an arc struck from the pivotal points of the suspending-arms j. Depending from the feed-plate are a pair. of integral lugs 7' the rear one of which is longer than the other, and formed on the rear end of the feed-plate isweight j which insures the normal closing of the spout when the shoe is free from its operating devices. The rear edge j of the spout depends nearer to the feed-plate than the forward edge thereof, so that when the feed-shoe is swung back to feed the carbid by a suitable mechanism (prefen ably by that hereinafter described) the carbid will be pushed or scraped olf the feed edge of the feethplate. Then as the shoe is forced to swing forward another charge of carbid is deposited by gravity upon it to be again forced off the feed edge when the shoe is again forced backward. The parts will be so proportioned that the movement of the shoewill be sufficient to supply the necessary quantity of carhid without moving it back to a position where the carbid would run by gravity alone directly from the feedspout over the feed edge of the shoe; butit willbe observed that the nearer the feed edge of the shoe app roaches that position the greater will be the supply of carbid.
Any suitable mechanism maybe employed for automatically controlling the feed; but I prefer the devices hereinafter described.
Pivoted to a bracket 7a,..secured to the upper edgeof the main casingyis-the outer end of a lever K, whose inner end is slidably and removably connected to the top of the gas-bell by means of a removable pin 7c, carried by a bracket k attached to the bell. Pivotally connected to and depending from this lever is a rod 7.2 which carries an inverted cup at its lower end, and directly below this cup is a vertical rod L, which is pivotally supported on one end of a lever M, secured to the projecting end of a rock-shaft N, journaled in the casing F at a point below the lower edge of the sealing-cap, said lever being on the outside of said casing and being provided with a weight m at its free end. The rock-shaft extends diametrically across the casing and is formed into a crank or bail on, which is adapted to engage the lugs j on the shoe and force the shoe backward and feed the carbid.
It will be observed that when'the bell is .held
up by the gas within it the lever K and its cup 70 will be also elevated, and the weighted lever M will be free to hold up rod L and crank it from engagement with lugs j there by permitting the shoe to remain normally closed; but when the bell descends below a predeterminedposition the lever K forces cup 7t down upon rod Land rock-shaft N, so, as to cause its crank to engage lugs j and there by force back the shoe and feed the car-bid in the manner set forth.
' It will be observed from Figs. 7 and 8 that the end of shaft N to which is attached lever Mis journaled in a striding-box carried by the casing. I The object of this is to prevent the escape of gas out into the sealing liquid and the escape of the liquid into easing F. It will also be seen that the shaft N is journaled above and forward of the axis of the pivots of the shoe, so that arcs of different magnitude will be described by the crank and the shoe, whereby as the crank swings backward it will pass up between the lugs and will remain therebetween on its return until the shoe reaches, or nearly reaches, its normal position, when the crank will by reasonof shortening the forward lug pass from between the lugs and is free to be automaticallyswung for ward out of the way by the weighted arm M,
thereby permitting the carbid-magazine to befreely lifted out of its casing and reinserted therein. It will be seen that by thus compelling the crank to remain in engagement with the lugs 9' until the shoe is brought back to its normalposition the shoe will be positively closed after each. discharge of the carbid, thereby supplementing the action of weight 9 and making it doubly sure that there shall be no improper discharge of the carbid.
To render it absolutely certain that the rod L shall rise and close the feed as the bell ascends after each discharge of carbid, I provide the following simple mechanism: An inwardly-extending bracket P is secured stationarily to the main tank adjacent to the bracket 70, its inner end being bifurcated to embrace rod L, and the two parts formed by this bifurcation are each provided with a cam Z, whose working face inclines upward and inward. From each of these cams extends downward and inward a lip Z, which forms, in effect, a continuation of the cam-surface, and pivotally depending from lever K is a hook Q, which inclines downward and inward and rests normally and works upon the faces of the cams and their lips as the lever K rises and falls. Upon the rod L is secured a lug R, which works up and down between the cams and their extensions as the rod rises and falls and which extends inward beyond the working faces of the cams and their extensions and is beveled off on its upper side. Should the weight on lever M fail to lift rod L and close the feed, the hook Q will engage under lug It and raise the rod, and as said hook continues torise it will slide up on the l purpose set forth, and means for automaticcam-faces and be Withdrawn from under the lug R, and thereby release the rod and permit the bell and its connected parts to rise to the limit of their movement.
It will be observed that by pivoting lever K at its outer end and detachably connecting it to the gas-bell the lever may be swung outward over the side of the apparatus in order that the bell may be removed at will, and in order that the carbid-receptacle shall be removable only when the lever K is thus thrown over and the apparatus is not in operation said lever is provided with a lateral arm S, which when the lever is in working position extends over the top of the carbid-receptacle, as shown in Fig. 2.
Having thus fully described my invention, what I claim is- 1. In combination, with an acetylene-gasgenerating apparatus, having a removable carbid-holder and a discharge-spout provided with a gate, the cover of the c'arbid-holder being provided with an upwardly-extending projection, of a movable device for simultaneously locking the carbid-holder and its cover in place and said gate closed, said device consisting of a vertically-movable rook-shaft provided with an arm at its upper end adapted to engage over said projection and an arm at its lower end adapted to engage said gate.
2. In combination with an acetylene-generator having a movable gas-bell and a removable carbid-holder and feed devices, of a lever pivotally supported and removably connected to the bell, and adapted to operate the feed devices as it rises and falls with the bell, said lever being provided with a part extending over the carbid-holder and preventing its removal while the lever is connected to the bell.
3. In an acetylene-generator the combination of a generator, a carbid-magazine having a feed-spout, a pivotally-hung feed-shoe thereunder provided with a pair of depending lugs, one lug being longer than the other, a crank pivotally hung above said lugs and to one side of the pivot of the feed-shoe and adapted to pass between said lugs, for the ally operating said crank.
4. The combination, in an acetylene-generator, of a carbid-holder having a feed-spout, a movable feed-shoe thereunder provided with a pair of depending separated lugs, a movable part for operating said shoe to feed the carbid said movable part being adapted to pass up between said lugs and impart to the shoe its feed movement and to positively return it to close the feed and being so mounted that it becomes disengaged from said lugs when the shoe is returned, and means for operating said movable part.
5. The combination with an acetylene-generator provided with a generating-chamber and a gas-bell, of a carbid-holder, a lever adapted to rise and fall with the bell, a vertically-movable feed-rod adapted to be depressed by said lever and feed the carbid when said bell falls, feed devices connected tosaid feed-rod, means adapted to automatically connect said lever to said feed-rod when the bell rises and thereby positively close the feed, and means for automatically disconnecting said means from the feed-rod when the bell reaches a predetermined point in its upward movement.
6. The combination, in an acetylene-generator, of a generating-chamber, a gas-bell, a carbid-holder, a lever adapted to rise and fall with the bell, a vertically-movable feedrod and feed devices connected thereto, a lug carried by said feed-rod, a hook attached to said lever and adapted to engage said lug 16th day of January, A.
