have made -a' certain Lnew and useful invention in .licetylene-Generators,fof which the following is a specification.
Tliis'inventionrelates to acetylene generators. y
The` object of the invention `isto .provide a construction and arrangement of acetylene` generator and accessory mechanism, which is simple` and elicient,rivherein 'the operations are readily and easily controlled, and wherein provision 'is inade-E fo'r -preventing explosion, accident, or other disastrous results diie tocarelessiiess, neglect or' disre A farther object of the invention is toprovide a generator of tlie'fcliaracter referred to, wherein means are provided for preventing a further supply of carbid or other @as producing material to the generator, after a supply thereto has become exhausted, until the generator tank has been: completely emptied and refilled.
A-fiirther object of the invention is to provide a ,generator ,of the Acharacter reerred to lia/ving means for preventing the generator tank from being relled until said tank has been iist completely emptied and drained. 4
A further object. of the invention is to provide. means for aiitomatically feeding the gas` producing material' into' the generator tank, andfor rendering the automatic feeding means inoperative Vduring the time thev generatoris vbeing drained.;

The 'invention consists suli'staiitiailyin the location, and relative arrangement or parts, all as will, be
f 'more'fiilly hereinafterset forth, as shown in the accompanying drawings, and iinally pointed out in the appended claims.

from ythe pointinarlied- 2 in Fig. l.' Fig.
is a broken vieiv in elevation taken from the. point marked 3, in i. Fig. l is. a viewY india-gram showing' the relative positions and operations of the controlling valves.
The same part is designated by the same reference sign wherever it occurs throughont the several'views.y
Actylene generators have been proposed, and are in iise. in which calcium carbid, or
k tor operating acetylene generators have not been faithfully i'olloived.A sometimes causing` disastrous results. lsiially the carbid. or other gas yielding material, is delivered into :i hopper from which it is fed or delivered into the generator tank. After the hopper has been emptied, and the pressure of generated gasin the tank begins to fall, the Water in the tank has become charged with :i residiiiini remaining after the generation of the gas, 'and the Water, by reason of such re'si'duiim,v is unlit for Vfurther use, and, together With the residuuin, shoiildsbe drawn oli from the 'tanlr'before a fresh charge of Vcarbid or other gas yielding material, is
supplied to the hopper. 'lf tlieviaterand resid-.uom .fi re not drawn oil or drained from the tank, or ar'eonly partially drawn oil or drained therefrom, tlironglicarelessness, neglect,"inattention, or otherwise, the sueee lingsiippiy ot'tresh carbid, or'ot-her gas yielding material, produces -a dangerous amount of lic-at; It vis among the special piirposes'oi my present invention to provide means ivi'icreiiy itis impossible to renew7 the fiiiiiply'ofca hid to the hopper' until after the tank hasheen completely emptied and drained and then properly refilled.
In order to carry out and accomplish the special objects and purposes of my invention, I propose to employ means whereby when a charge of carbid in the feeding hopper becomes exhausted by being fed into the generating tank, and the pressure of gas in the tank begins to fall, the gas contained in the generator is automatically liberated through a suitable vent While at the same time, the vgenerator tank is opened to a suitable drain connection to. permit the water and residuum to exhaust and drain therefrom. When all of the gas as well as the residuum and water have thus escaped or completely dr ined vfrom the tank, the exhaust vent an drain connections are closed and a supply connection opened for a fresh supply of water into the tank. This open-A ing of the water supply to the tank, in accordance with the principles of my invention, cannot be made, however, until after the gas exhaust vent and water and residuuni drum connection have been closed. lt is also important and necessary to prevent the supply of additional, or a fresh/charge of the carbid to the hop ei until the generator tank -is again filletfJ with a fresh supply of water to the proper level, and the fresh water supply'connection is closed. It is also important that the auto-matic feed for delivering the carbid from the hopper into the generator tankvbe locked in inoperative position from the time when the gas vent and residuum drain connections are first opened until after the entrance for the figesli supply of carbid to the hopper is again closed.
In accordance with the principles of my invention I provide means for insuring the carryin out of these various operations in sequential order, and by means which are not dependent upon the care or attention of an attendant.
Referringto the drawings, reference sign 4 designates the generator tank. Atl one side of this tank is arranged a vertical shaft 5 carrying a bevel gear 6, at. its upper end arranged to mesh with and drive a similar bevel gear 7, of equal size therewith, said gear 7, being carried by a horizontal shaft 8, suitably journaled in bearings mounted upon the upper end of the generator tank 4. Connected with the gear 7, to rotate there,- with, is a disk 9, having an engaging shoulder 12. Loosely mounted on shaft 8, to revolve thereon, is\a sheave or drum 13, around which is wound a chain or otherl suitable flexible connection, which passes overidlers 15, and having a handle 16, connected to one end thereof, and a weight 17, connected to the other end thereof, said Weight being held and guided by the guides 18. The drum or sheave 13, carries a pawl 19, which cooperates with the shoulder .or detent 12, of disk 9, the arrangement being such that when the sheave or drum 13, is rotated in a direction contrary to the travel of the hands of a clock, the pawl 19, will travel over and freely pass the shoulder 12'. When, however, the sheave or drum 13 rotates in the same direction as the travel ofthe hands of a clock, the pawl 19, will engage the shoulder 12, and cause coincident rotation of disk 9, and with it gear 7, and shaft 5. The arrangement is such that when the handle 16 is pulled downwardly, the pawl 19, is carried around with the sheave or drum 13, riding freely over shoulder 12, while at the same time the weight 17, is raised. This weight must be raised siitiiciently high so that the drum 13 will make a complete revolution before the pawl 19, is brought into position to rengage the shoulder 12. Unless this is done, the release of handle 16, will not result in coupling drum 13 and disk 9 to revolve together, but when the weight 17, is raised to a sutiicient height for the pawl 19, to engage Vand/lock against shoulder 12, the release of handle 16, to permit the weight to again descend, causes rotative movement to be imparted to shaft 5, through the intermeshing gears v6 and 7 as above explained. lI so arrange these parts that the movement of the weight 17, from its extreme upper position, indicated in dotted'linesat 10, Fig. 2, to its extreme lower position indicted by dotted lines at'11, will cause one complete revolution to be imparted to shaft 5.
The descending movement of weight 17 is effected in four successive stages. The extreme upper position of the weight corresponding to the first or initial position of the parts in the cycle of sequential operation of the apparatus, as above indicated. The downward movement of the weight is arrested at the completion of its first stage of movement :by a movable stop device 28, arranged in its descending path, the position of arrest of said weights by stop device 28, marking the second position of tlie parts-in the cycle of operation, this first stage of movement of the weight effecting a onequarter revolution of shaft 5. lVhen the weight is released from stop device 28, it resumes its descending movement until it is arrested by movable stop device 29, arranged in its path, at the completion of its next stage of movement, leaving the parts in their third positions in the cycle o`f operation of the apparatus. During the movement ofthe weight from stop device 28, to .stop device 29, another quarter revolution is imparted to shaft 5. Then the weight 17, is released from stop device 29, it continues its downward movement until arrested by movable stop device 30, this being the completion of the next stage of movement leaving .the parts 'in the fourth position, and imparting another one-quarter revolution to shaft 5. When the Weight 17, is released from stopv device 30, it continues its ilownwartl movement to its lowermost limit es indicated at dotted lines Il, liw f f. thereby imparting the iinal oneouarter revolution to sbaf, and completing the one entire revolution of said Shaft necessary for .the accomplishment of the full purposes; :1nd operations of the apparatus. Should the weight- 17, he again raised from any one of its inte-fine diete stops before reaching its extreme lower position, there will loe no result, since such rinsing movement will not he suiiieient to rotziriljv7 displace sheave 13, through the extent necessary for the pmvl t9, to rengage with Shoulder l2. The weigl'it must reach its extreme lower posilion, unil the drum i3. :loll .shaft 5. must eoinplete one entire revo lotion iu orrler to bring the parts inlo their relative poezitions for repeating 'the eyeleof operations in their sequential order.

In accordano@ with the principles et my invention, I provide means for automatically feeding the calcium carbid into the generator tank, and for controlling the opening through which the carbid is introduced into the tank. in` such manner that except at a predetermined stage of the sequential operation of the apparatus` the feed opening for the carbid, is maintained inaccessible, and I provide means for automatically controlling the feed4 of the carbid into the tank by the pressure of the generated gas, and means for automatically lock ing the feeding mechanism against operation When the feed opening for the introduction of the carbid is rendered accessible, thereby not only preventing the operation of the feeding mechanism While a fresh charge of carbid is being introduced to the feed hopper, but also controlling the operation of the feed mechanism by the pressure of the generated gas. I will novv describe means embodying my invention for accomplishing these results. Reference numeral 49, Fig. 3, designates generally a clock-Work mechanism arranged to be driven and actuated by a Weight 50, the cord or chain 82. which suspends the weighL 50, being` Wound upon a drum 5l, to the axle or shaft of which is connected a large gear Wheel 83, arranged to mesh with and to drive a pinion 84, carried by a shaft 52, which extends down into the generator tank through any suitable arrangement of stuffing-box and carries a feed disk 53 upon the lower end thereof. The Weight is raised after it rims down in the customary manner of 'Winding up the Weight of a clock.
Arranged in the upper end of the generator tank 4 is the feed hopper 54 into which the calcium carbid or other gas yielding material is introduced thrcgh an opening in the top of the generator tank arranged to be closed by a removable plug (35. When the carbid is introduced into the 4.5 hopper 54, it descends therein to the central opening in the loivci end thereof. The disk 53. forms a bottom for the lower open delivery end of the hopper, but said disk is spaced dowiiivardly below the extreme lower end of the hopper a sufficient distance to permit the carbid to be delivered from the hopper over the peripheral edge of the disk 53. In order to cause the carbid to be delivered over the edge of disk 53 so as to be dropped therefrom into the tank 1. I provide the lower endv of the hopper ivith displacing plates 8:7,.arranged around the edge of the cpening or mouth of the hopper.'
Attached to the shaft of drum 5l, is a stop wheel or dif-'lt 55. In order to control the operation of the feeding disk 5?). autoniaticallv, by the pressure of the generated gas. so as to maintain a uniform pressure of gas. l provide a pipe connection tI-l, to
. '1r from the u ier end of the generator e iw g tank into the casing of a diaphragm device GO, and I arrange this diaphragm device to control an arm 8G, carrying an adjustable weight 62 and connected by ine-.ins of a link 87 with one arm of a detent 56, pivoted at 5S, intermediate its ends. The free end of said detent 56, isarranged to bear againsty the surface of the disk By this arrangement it will be seen that when the gas pressure exceeds a predetermined degree'in the generator tank, the lever 86 is raised by the diaphragm device 60 thereby rocking detent 56 into engagement with disk 55 and hence arresting the clock-Work mechanism, and of the feeding disk 53. Nhen the pressure in the generator tank falls again, the Weight 62 will rock lever 86 downwardly thereby releasing the detent 56, and hence causing the clock-Work mechanism to resume its operation, and consequently again resuming the feed of the carbid from the hopper into the generator tank.
In oi'der to render inaccessible the feed opening through which the carbid is delivered into the hopper 54, except at a given stage in the cycle of operations, I mount on the shaft S, a drum 64 to revolve therewith. the plug G6 being located immediately be low said drum, so that said plug is iendered inaccessible for. removal until said drum rotatively displaced sufficiently for an openingl indicated by dotted lines at G5, see Fig. 2, is brought into position directly over said plug. This opening is so located as to be brought into position over plug 6G to permit the removal of the latter only when the proper stage in the operation of the apparatus is reached. This point is reached when the weight 17 is resting on stop device 30.
It is desirable to arrest the operation of the clock Work feeding mechanism during the time the plug (5U is accessible for removal. To acconiplish this result I mount a cam arm 63 on the end of shaft S, and arrange the saine to engage a detent 57, and liftithe same out of locking engagement with the disk 55, at the proper time in the operation of the apparatus. The arrangement of these parts is such that the detent 57 placed in detaining relation with respect to disk 55, and is only liberated therefrom when the Weight 17 is in its top or bottom position.
ln the lower part of the generator tank is an agitating device 67, operated by a crank 85:, outside of the tank to facilitate the cleaning out of the tank while itr is beine' drained.
`In order to insure a proper level of fresh water supply to the tank, I provide the upper end of the auxiliary tank QOvWith an overflow pipe connection ,68, see Pig. 4.
