SPECIFICATION forming part of Letters Patent No. 681,166, dated August 20, 1901. Application filed September 19, 1900. Serial No. 30,500. (No model.)

- T wZZ whom it may concern.-

Be it known that I, GEORGE W. COLLIN, a citizen of theUnited States, and a resident of Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Oarbid-Feed Mechanism for Acetylene-Gas Machines, of

which the following is a specification.

Myiinvention relates to new and useful improvements in acetylene-gas machines and 1 refers especially to carbid feed mechanism therefor.

I It is the object of my invention to improve upon said mechanism for the above purpose by producinga more positive, regular, and desirable feed, whereby uniform quantities or charges of carbid are successively fed from a hopper; further, to devise said mechanism 1 in as compact a manner as possible, and,

finally, to make it substantially automatic in its feeding operation, the same being regulated by the quantity of gas retained within the expansible tank, which is present in most forms of acetylene gas machines.

I haveshown my apparatus applied to a i complete but diminutive form of machine in the main figures of the drawings, said machine being, as before stated, of small design,

. p adapted for portable purposes and especially applicable for illuminating single rooms by the attachment of one or more burners.

it With the above objectsin view myinvention resides and consists in the novel construction andcombination of parts shown n 335 upon the accompanying drawings, forming a part of this specification, upon which similar characters of reference denote like or corresponding parts throughout the several figures,and of which-- t Figure 1 shows a side elevation complete of a portable gas-machine containing therein my improved carbid feed mechanism. Fig.

2 is a central vertical cross-section of the machine shown in Fig. 1 and illustrates clearly the. feeding apparatus and the mechanism lrequires.

which the water-wash is filled.

generator. Fig. 4 is a detail side view of the feeding mechanism shown in Fig. 3. Figs. 5 and 6 show a central vertical longitudinal section and a detailed end elevation, respectively, of the disengaging mechanism of the feeding device employed in Fig. 2.

Referring in detail to the characters of reference marked upon the drawings, A indicates a tank having an inner and outer wall, forming a water seal for the movable bellB. This bell is of the usual construction, except that it is provided with a water-wash chamber G in its top and a gas-pipe D to convey the gas from the bell proper into said wash, from whence it rises into the space above said body of water. A burner E is shown attached to the top of the bell and leading from said gas-chamber. It will be obvious, however, that suitable piping and several burners may be substituted for said burner if occasion F represents a cap by means of The interior of the bottom of the tank A may be provided with a suitable bucket or other receptacle G, which in practice is filled with water and receives the carbid to be dissolved. From this receptacle the gas rises up through the several parts of the machine, as indicated by the arrows, and emerges under the lower part of the bell, from whence it is fed through the water-wash, as before explained.

The carbid-feeding apparatus, as illustrated in Fig. 2, is designed to operate by means of a windable spring, which latter is automatically started and stopped by connections H indicates a hopper for the reception of lump carbid, and I indicates an opening therefor, by means of which said carbid is introduced from time to time for consumption. The lower portions of the hopper are substantially conical shaped, terminating in a spout J, having its discharge upon the feed-drum K, the latter being preferably provided with a toothed serrated face, as indicated. This drum in practice is mounted upon a shaft which may be operated by pawl, ratchet, and pulley connec-' tions L, with the common form of movable bel of a gasometer, or there may be employed a worm-and-gear connection M, as shown in Fig. 2, wherein I employ upon the shaft of said worm a spring N to constitute the driving mechanism. I also employ a pawl and ratchet-wheel O to hold said spring in check except when released by the action of the bell. This releasing mechanism comprises simply a bell-crank lever P, having a slidable link Q attached to its lower end, which has an inclined or cam surface Q to engage the pawl of the ratchet-wheel in a manner to raise and lower it from said ratchet-wheel by the inward and outward movement of said arm and link, it being apparent that the upper end of he rm Will be engaged by the bell when it descends, thus forcing out the lower end of aid arm in a manner to cause said cam-sun face. to engage and raise the pawl from the ratchet, permitting the spring to act and through its connections operate the feeddrum, feedi g the carbid down into the generator-bucket before mentioned.

A further and essential feature of my feeding mechanism is the rotatable toothed regulator R, which is loosely mounted in any suitable way as, for instance, on a bracket S, as shown in Fig, 2, or in swinging arms T T, as HdiQ Qd in. Figs. 3 and 4. This regulator is rotatahly mounted over the feed-drum and in d rect lin of travel of the carbid as it is fed out of the chute. In'practice the teeth of the egula or are engaged by some of the teeth of e (1 7 1 1 in a manner to rotate said regulaton he pu pose of this regulator is to prevent the carbid from running and to cutout uniform g s from the spout of the hopper, h ch cha g are deposited in the generator by the movement of the feed-d rum. The regulator is provided with, large pockets to strada e in te quantity of carbid, and should it happ to in isi e unusually large lumps the construction is such as will permit of the regulator moving outward, riding over said carbid, passing it down over the feed-drum, and again settling down to its normal position. There may be any desired number of these serrations in the feed-drum, and the. size or shape of them can also be varied to accommodate the particular size of carbid used.

A feed as herein illustrated and described is foundjto be very desirable, since the carbid can be handled in given quantities and relied upon to pass down with each movement of the mechanism-and,furthermore, its movementis not liable to become retarded by reason of the sediments from the carbid and gas.

Having thus described myinvention, what I claim, and, desire to secure by Letters Pat.- nt, is-

1. In an acetylene-gas generator, the. combination of carbid-feed mechanism comprising a hoppe bearing a chute, a serratedfaced feed-drum at the mouth of said chute, means for driving said drum, connections for an tomaticall y starting and stopping said driving mechanism, and a toothed regulator meshing with the serrations of the feed-drum to operate upon and cut out given charges of lump carbid from the chute of the hopper, and links in which said regulator is yieldably mounted to permit the same to rise, substantially as described.

2. In a carbid-feeding mechanism for gasmachines, the combination with a hopper, of a serrated-faced feed-drum at the mouth of Said hopper, means for driving the drum to feed the carbid, connections between said driving mechanism and an expansible gasreceiving bell comprising a part of said machine, whereby said driving mechanism is started and stopped automatically by the movement of the bell, arotatable toothed regulator meshing with the serrations of the feed-drum and loosely mounted in the line of travel of said carbid in a manner to retard its flow, and means to permit said regulator to rise and allow the carbid to pass thereunder.

3. A carbid-feed mechanism for a gas-machine, comprising a hopper having a chute, a serrated-faced drum at the mouth of said chute, means for automatically operating said drum to feed uniform quantities of carbid from said chute, a toothed regulator meshing with said feed-drum and adapted to cut out given quantities of bulk carbid from the hopper, and links in which said regulator is yield ably mounted, to permit carbid to pass thereunder, substantially as described.

4. A carbid-feed mechanism for gas-machines comprising a hopper adapted to retain rough carbid and having an exit opening therefrom, a feed-drum at said opening with serrations therein to feed the carbid from the hopper, a. toothed regulator having pockets to operate in conjunction with the serrations of the drum and cut out quantities of the serrations for the carbid, swinging links in which said regulator is mounted to permit the regulator to be raised from the drum by the reception of an excessive charge of carbid.

5. In an acetylene-gas, machine, the combination with the generating-chamber, an ex pansible bell covering the same, a carbid-hope per located under said bell and provided with an opening, a serrated feed-drum atthe mouth of said opening adapted tov receive the carbid from the chute and discharge it in the generating-chamber, means for operating said cylinder, mechanism for automatically start ing and stopping said means by the movement of the bell before mentioned, a toothed carbid-regulator at the mouth of the opening over the chute, meshing with and adapted to operate in conjunction with the feeding-drum to out out and deposit the carbid in uniform charges, and means as shown for affording an outward yieldable movement of said regulator when the carbid passes under it.

-6. In a carbid-feeding device for acetylenegas machines, the combination with a hopper adapted to contain lump carbid and having a suitable chute, of a pair of serrated-faced wheels to separate and allow the carbid to IO pass thereunder.
