EDWIN MILLER, OF DETROIT, MICHIGAN, ASSIGNOR TO MILLER LIGHTING COMPANY,
ING., OF DETROIT, MICHIGAN, A GORPORATIQN.
CARBID-FEEDER.
Specification of Letters Patent.
Patented May 14, 1912.
To all whom it may concern:
Be it known that I, EDWIN MILLER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Carbid-Feeders, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to carbid-feeding devices for acetylene gas generators, and it has for its object a feeding device which will readily feed the carbid, and which embodies a simplicity of construction, which makes both for proper feeding and cheapness of manufacture.
It is well known that car-bid feeds with diliiculty if the device has been used for some time, and it is very essential that all useless pivots and levers be eliminated, as the carbid works in between these connections and prevents the apparatus from performing its work. I have eliminated this difliculty by providing a minimum number of pivots for the freedom of action which I achieve.
In the drawings :-Figure 1, is a vertical section of the carbid-magazine and cover. Fig. 2, is a similar view showing the feeding device after it is moved into another position in which the measuring-pan is in position under the magazine'mouth.
The feeding device is used in connection with a generator (not shown) directly be low the carbid-magazine and with a gas bell which is placed at the side of the magazine, and which rises and falls as the amount of the generated gas varies. This gas bell is not shown in the construction, and I do not care to limit myself to any form of actuating device to control the feeding mechanism, as such is no part of my invention.
1 indicates a tubular neck which rises from the casing inclosing the generator chamber below.
2 is a magazine having at its sides hooks 3 which pass over the top of the neck 1, and hold the magazine in position above the opening of the neck into the generating chamber. The magazine is preferably made in cylindrical form tapering at its bottom into a spout 4. At each side of the spout a bracket 5 is riveted, extending from the point of attachment downward considerably below the mouth of the spout and beyond the feeding device hereafter to be described. A standard 6 is also attached to the side of the magazine near the top of the tapering portion and extends downward to the level of the end of the brackets 5. The brackets and the standard form a supporting means for the magazine after it has been lifted out. Inside of the brackets 5, the interrupter-pan 7 swings upon a shaft 8 which passes through the side walls of the spout and is supported thereby. This pan, the arms 9, which are fixed to the shaft 8 at each side of the spout, and the ear 10 at the bottom of the pan portions, comprise a single casting. At the side of the interrupterpan 7 a dumping-pan 11 is supported on trunnions journaled in the brackets 5 at either side. This dumping-pan is cast in one piece and comprises a main pan portion, trunnions 27 at each side, lugs 13 at the edge of the receptatcle, and lug 12 at one side of the receptacle. It is the oflice of the interrupter-pan 7 to ordinarily remain under the mouth of the spout and prevent carbid from dropping into the generating chamber. When the interrupter-pan 7 is in this position the dumping-pan 11 is vertically inclined and the lug 12 is almost directly above the lugs 13. To the lug 12 is attached a rod 14 which leads up above the neck 1, where another rod 15 is pivoted thereto, extending down below the side wall of the cover 16, and at this point a third rod 17 is pivoted to the rod 15, extending above to a point where it is pivoted to a weighted lever 18. This lever 18 is adapted to be operated in the well-known way by an arm 25 attached to the gas bell, so that when the volume of the gas has fallen to a predetermined point, the lever 18 is forced down at the end to which the rod 17 is attached, causing the rod 14: in turn to force the pan 11 downward; the pan 11 then swings on its trunnions 27, taking a position directly below the mouth of the magazine, causing the interrupter-pan 7 to swing to the side of the spout by reason of a bail-like link 19 connecting the ear 10 of the interrupter-pan 7 with the lugs 13 of the dumping-pan 11. The contents of the magazine then pour into the dumping-pan 11 and when the volume has fallen below a second predetermined point the arm 25 slips off the end of the lever 18 and the weighted end pulls the rods upward, drawing the dumping-pan 11 back into its initial position. It is seen that the dumping-pan 11 is then in almost vertical position and that its contents will readily slide out without any sticking in the bottom. In order to keep the carbid about the mouth of the magazine loose, an agitator pin 26 is attached to the shaft 8.
20 indicates the receptacle for reserve carbid supply. This receptacle is constructed with the center of gravity above the pivoting so that the receptacle is ordinarily not balanced. It is held in upright position by the carbid of the magazine inclosing it on all sides. The cover 16 is then placed over the magazine and a bail 21 swung over the handle 22 so as to prevent the pressure of the gases from lifting the cover. The top of the cover lies against the reserve supply receptacle E20, preventing it from tipping from its upright position. Nhen the supply of carbid 'is exhausted in the magazine the cover 16 is then slightly lifted and the receptacle 20 tips, dropping its contents into the interrupter-pan T, which is then under the spout.
A water-jacket 23 incloses the entire mechanism, including the magazine, the neck and the cover 16. The space between the waterjacket and the neck is filled with water in which the cover 16 rides, the water preventing any escape of gas.
It will be seen that the pans and their connections are constructed integrally as far as possible, and that the parts of the feeding device are reduced, thereby eliminating parts into which the carbid may get and cause inoperativeness of the mechanism.
It is a feature of this construction that both pans swing freely on separate pivots so that they can describe the full are necessary for properly swinging in and out of working position.
hat I claim is l. A carbid feeder, having in combination, a magazine provided with a delivery spout, an interrupter-pan arranged to swing thereunder, a dumping-pan arranged to swing below the spout and interrupter-pan, a link connecting the interrupter-pan with the adjacent side of the dumping-pan, and reciprocating means and a weight for returning the same connected with the dumping-pan opposite the link connection, for automatically swinging the pans, alternately, below the delivery spout, substan tially as described.
2. A car-bid feeder, having in combination, a magazine provided with a delivery spout, an interrupter-pan arranged to swing thereunder, a dumping-pan arranged to swing below the spout and interrupter-pan, a link connecting with the adjacent side of the dumping-pan, and reciprocating rodconnections, attached to the dump-pan at the extreme opposite side of the link connection and passing to the outside of the generator, and a pivoted lever having a weight at one end for actuating the rod-connections and automatically swinging the pans alternately below the delivery spout, substantially as described.
In testimony whereof, I sign. this specification in the presence of two witnesses.
