CARBID-FEED MECl-IANISM.

oceaan.

To all whom it may concern:

Be it known that I, AUGUSTUS E.' Sor-Inie- Dniz, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful improvements in Carbid-Feed l\lechanism, of which the following is a specification.

This invention relates to improvements in carbid feed-mechanism.

In carbid feed-mechanisms now in use, the feed-valve is generally open to its full extent when the gas-bell of the gas-holder is at a predetermined low point, which position the gas-bell assumes when the gas within the holder is consumed, or almost consinned, and t-he feeding of carbid to the gasgenerator ceases. Cessation of the feeding action oftentimes occurs when the carbid bridges or clogs within the carbid receptacle, and experience has shown that the controlling mechanism between the feed-valve and gas-bell is liable to become disarranged or temporarily ineffective in the performance of its proper functions. At such times, excessive generation of gas is likely to take place, which is not only wasteful, but dangerous as well. When the carbid is bridged within its oontainingreceptacle and the valve is open, the entire contents of the carbid-receptacle, or at least an excessive quantity of carbid, is likely to be charged into the gas generatingchamber onI the slightest jarring of the machine, causing generation of gas considerably in excess of the capacity of the machine. 1When the controlling mechanism fails to properly respond to the action of the gas-bell, overcharging of the gas-generating-chamber is also likely to occur, and serious accidents result therefrom. Overcharging of the carbid into the generating-chamber is known to be dangerous, and provision has been made to avoid this during the proper operation of the machine.

lt is the purpose of my invention to avoid overcharging at all times, and for this purpose l provide an auxiliary-valve or closure for the carbid-receptacle operated by the primary or feed-valve, and so arrange the same that when the primary or feed-valve is open to its full extent, or if desired to any predetermined point, the auxiliary-valve is moved to close the outlet of the carbid-receptacle. It has also been found that, when Specification of Letters Patent.

serial No. 395,576. i

first starting the generation of gas by hand to set the machine in operation, the operator may carelessly open the feed-valve unnecessarily wide, which permits the carbid to drop into the gas generating-chamber in larger quantities than desired, causing overcharging of the gasometer with the generated gas, which is not only wasteful, but dangerous as well. y

To these ends the invention consists in automatically-controlled mechanism for closing the outlet of the carbid-receptacle when the feed-valve is open `and its controlling-mechanism fails to close the same; and in controlling-mechanism which limits the extent of rotation of the valve-shaft when starting the generation of the gas; and it further consists in the construction, arrangement, and combination of parts to be hereinafter described and particularly pointed out in the appended claims.

Referring to the drawings,-Figure l is a side elevation of a valve-chamber located in a gas-generator between the carbid-receptacle and the gas generating-chamber, and the controlling mechanism which controls the feed of carbid to the gas-generatingchamber, and showing also a portion of the carbid-receptacle, the gas-generating chamber, and gasometer. Fig. 2 is a side elevation of the valve-chamber with a part broken away. Fig. 3 is a vertical section taken 'on line Bu, Fig. 2. Fig. l is a horizontal section taken on line a-e, Fig. l. Fig. 5 is a vertical section taken on yline 5-5, Fig. 3. Fig. 6 is asectional elevation similar to Fig. 2, with the valves in inverse relation; the valve-chamber only being shown. Fig. 7 is an enlarged detached perspective view of the primary or feed-valve. Fig. 8 is an enlarged perspective view of the auxiliaryvalve or closure. Fig. 9 is a horizontal section taken on line 9*.9, Fig. 1. Fig. 10 is a top plan view of the controlling lever and horizontal section through the adjacent portion of the gasometer, the stop-pawl of the controlling-lever being swung outward to limit the movement of the lever. Fig. 11 is a side elevation of the controlling lever with its parts in normal or locked position. Fig. l2 is a perspective view of the controllinglever with its parts arranged to limit the movement thereof. Fig. 13 is a cross-section taken on line 1li- 13, Fig. 11. Fig. 14C is a Fig. 15 is a detached perspective view of the stop-pawl.

Referring to the drawings in detail, like numerals of references refer to like parts 1n the several figures.

The numeral 10 designates the valvechamber, usually located between the carbidreceptacle 11 and the gas-generating chamber 12, into which latter the carbid is to be charged in proportion to the consumption of O'as. C 13 designates the gasbell having a slotted vertical rod 14 secured thereto, as is common in gas-generators. Extending into the upper end of the valve-chamber 10 1s a hopper 15 open at its lower end. This hopper is an extension of the carbid-receptacle and forms part thereof. An oscillating segmental feed-valve 16 is movable back and forth underneath the hopper to open and close the same; it having radial arms 17, to one of which is secured the end of an operating or valve-shaft 18 forming part of controlling-mechanism 19 and passing through a stuffing-box 2O in the wall of the valvechamber. Formed on the other of said radial arms is a stub-shaft 21 having its axis coincident with the axis of said operating or valve-shaft and being journaled in a bracket or support 22 secured to the wall of the valve-chamber. Secured to the operat-v ing-shaft 18 is a controlling-lever 23 which enters a slot 24 in rod 14, and therefore, when the gas-bell rises or lowers, said shaft is rocked, causing the feed-valve to oscillate underneath the hopper 15 to open or close the outletof the carbid-receptacle; the extent of opening being in proportion to the consumption of gas when the machine and its various parts are in proper working order.

When the carbid in the carbid-receptacle and the generated gas in the gas-bell is consumed, or when the carbid bridges or clogs in the carbid-receptacle and fails to feed, the gas-bell gravitates to its lowest point, causing the feed-valve to open to its full extent through the intervention of the controlling mechanism. In gas-generators now in use, it is necessary to provide means to prevent the replenishing of the carbidereceptacle until the feed-valve or mechanism is closed, necessitating the use of expensive and complicated mechanism between the controlling-mechanism and the cover or inlet closure of the carbid-receptacle. Such means, while it avoids the carbid when fed into the carbid-receptacle, falling directly into the generating-chamber, it does not prevent the accidental and excessive feeding of the carbid on a slight jar of the machine in the event of the carbid bridging or clogging within the receptacle; or when for any other reason, casual cessation of the feeding of i carbid takes place.

T0 eliminate the above mentioned and other objections, I provide means for closing the outlet of the carbid-receptacle when the feed-mechanism is moved to a certain point within the range of its movement, which point may be predetermined and actuation of said closure-means caused when the valve is only partly open, or when open to its full extent, as may be found desirable in each case; depending also on the type of feed-valve used and the extent and direction of its movement. This closure means is in the form of mechanism comprising a rockspindle 25 journaled in a bracket 2G on the wall of the valve-chamber and having secured thereto a curved auxiliary valve or closure 27 which is normally inactive, as shown in Fig. 6, and adapted to be swung against the outlet of the carbid-receptacle when the feed-valve is open, as shown in Figs. 2 and 5. Said auxiliary-valve or closure is actuated by an extension or arm 23 on the feed-valve or the operating-shaft, as may be desired; said arm having a laterally ex tending toe 29 and its end curved, as at 30; said curved end being in an arc of a circle having its axis coincident with the axis of the operating-shaft. Secured to rock-spindle 25 is an arm 31 having a curved edge 32 corresponding with the curved end of arm 28.

Vhen the feed-valve is opened to a certain point, the toe on the arm 23 comes in contact with the curved edge 32 of arm 31 and raises the latter, causing the closure or auxiliary-valve 27 to swing upward against the outlet of the carbid-receptacle to close the same. When said auxiliary-valve is closed, the curved arm 28 is in contact with the curved edge of arm 31, and as the contacting surfaces correspond, the feed-valve is free to move while holding thc closure or auxiliary-valve in its closed position.

The controlling-lever 23 comprises twolever members, 33 and 34, a lock-member 35 whereby the two-lever members are held in locked condition, and a stop-member 3G. Lever-member 33 is secured at a point be tween its ends to the operating-shaft and at one end it has a laterally extending lingerpiece 37 by means of which the shaft may be operated manually, which is necessary when starting the machine in operation. The opposite end of said lever member is curved downward, as at 38, and has pivotally attached thereto lock-member 35 which has a long-arm 39, a short-arm 40 through which is passed the pivot pin by means of which said lock-lever is attached to lever-member 33, and a connecting-arm 41 arranged at an angle to

arms

39 and 40.

The lever-member 34 is loosely mounted on the operating-shaft and extends with its outer end beyond the corresponding end of lever-member 33 so as to enter the slot in the rod 14 secured to the gas-bell. Normally, lever-member 34 is locked to member 33 by the lock-member 35, as shown in Fig. l1; the rear end of member 34, entering the space between the long and short arms of the lock member and having its extremity rounded, as at 45, to act against the curved lower edge 46 of the long arm of said lockmember to raise the latter out of locking position which permits manual actuation of the valve-shaft without regard to the position of the gas-bell or the actuation of the same. Said lock-member is provided with a toe 47 designed to strike a stop 48 proj ecting laterally from the inner extremity of lever-member 33 for the purpose of limiting the upward movement of the lock-member. A retractile spring 49 having its ends attached to the lock-member and lever-meinber 83, respectively, serves to retain the lockinember in locking position when the levermember 34 is swung into normal position with respect to its co oerating lever-member 33. The lower edge of the lock-member has the axis of its curved edge coincident with the axis of the valve-shaft so that when lever-member 33 is actuated to rock said shaft, the lock-member travels back and forth in contact with the end of lever-ineinber 34 without changing its position on levermember 33.

The outer -free end of the long arm of lock-lever 35 is enlarged and slightly curved at its extremity to permit of conveniently raising the same by placing the thumb thereagainst and exerting an upward pressure thereon.

Lock-member 35 has pivotally secured thereto, stop-member 36 by a pivot-pin or screw 50 passing through said stop-member and taking into the upper edge of the lockmember. A stop 51 in the form of a lip extends from the upper edge of said lockmcmber and serves to limit the swinging movement of said stop-member, which latter has at its inner or pivotal end a notch 52 providing

abutments

53 and 54 which strike stop 51. fhen the several parts of the controlling-lever are in normal position, stop-member 36 lies over the lock-member as shown in Fig. 9 but on swinging the lockmember upward to permit independent movement of lever-member 33, the stopmember swings outward at an angle to said lock-member and in the path of a stop or projection 55 on the gasometer, designated 5G in which the gas-bell is confined. By this arrangement, the valve-shaft is limited in its rocking-movement when manually actuated to set the machine in operation, and consequently the carbid is fed'from the carbid-receptacle into the gas-generator in small quantities, the opening of the feedvalve being in proportion to the extent of movement of the valve-shaft.
