CARBlD-FEED FOR AGETYLENE-GAS GENERATORS.

To a/Z whom, it ina/y concer-71,:

Be it known that we, NORMAN D. SHAFFER and J osIAH S. BENTON,y citizens of the United States, and residents of Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Carbid-Feeds for Ace tylene-Gas Generators, of which the following is a specification. y

This invention is an improvement in carbid feedv devices for acetylene gas generators, and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view of the improved device with the pan in charging position, that is to say, in position to receive its charge of carbid from the hopper. Fig. 2 is a vertical longitudinal section of the improved device with the pan in discharging position. Fig. 3 is a side lview of a portion of the acetylene 'gas machine showing the devices which may be employed for oscillating or rocking the feeder. Fig. 4 is a front elevation of the feed devices. Fig. 5 is a top plan view thereof. Fig. 6 is a front perspective view, and Fig. 7 a rear elevation of the feed devices, and Fig. 8 shows a somewhat different shape of pan and interrupter from that shown in Figs. 1, 2, 3, 4, 5, 6 and 7.

As shown, the feeder comprises a main discharge pan A, and an interrupter or cut-off pan B, rigid with said pan and both of said parts being secured to a shaft C, by the rocking or oscillation of which the desired operating movement may be given to the feeder. This oscillating motion may be given the feed devices by various mechanisms, and we do not desire to be limited in the broad features of our invention to any particular means for oscillating the feed devices. For the purpose of illustration, however, we have shown in Fig. 3 oscillating devices which form a part of Patent No. 685,545, issued October 29, 1901 to White and Harbaugh, and the oscillatingdevices shown and more fully described in the said patent may, when desired, be used for oscillating the shaft and feed devices connected therewith, or such oscillating motion may be given in any other suitable manner, it being understood that in operation it is desirable to shift the feed devices from the, pan charging position,

shown in Fig. 1tothe discharging position shown in Fig. 2, the pan when as shown in Fig. 1 receiving its charge of carbid, and when shifted 'as in Fig.,2, discharging to the water in the generator, and the interrupter B being in such position, shown in Fig. 2, shifted below the discharging spout D of the hopper D to prevent the carbid from passing freely from the ho per to the water below.

As s own, and as preferred, the pan A and the cut-off orinterrupter B are rigidly constructed as one unit,l and are secured to the shaft C by meansof the brackets E having the collars E riveted at E"Z or otherwise suitably secured to the said shaft C, as shown in Figs. 1, 4 and 5. By thus constructing the feeder as one unit we are able to eliminate all pivots or bearings between parts within the generator F, and exposed to the deposits of lime, etc.

The interrupterB is spaced apart at its sides from the pan A by the braces G, and it will be noticed, especially from Figs.v 1, 2, 5 and 6, that the interrupter overlying the pan discharges at b in one direction, whilethe pan A discharges at a in the opposite direction, the discharge of the interrupter B being toward thel closed end A of the pan A, as best shown in Fig. 2, so that the interrupter will discharge tothe pan A as the parts are being shifted to the position shown .in Fig. 1, while the pan A will discharge when the parts are in the position shown in Fig. 2, in which position the interruptor will -be shifted below the spout D of the hopper to prevent the free discharge of carbid from the said hopper.

As shown,V and preferred, the pan has its bottom divided by a longitudinal ridge A2 into two separate discharge troughs A3, and for convenience in manufacturing the device from sheet metal, which is the preferred material employed, we make the pan A with the bottom plate A4 bent to produce the troughs A3 and the intermediate ridge A2, and the side plate A5 which extends continuously from the discharge end of the pan aro und the back thereof, as shown. The bottom plate A4 is lapped along the outer side of the side plate and may be secured thereto by soldering, riveting, or otherwise, as desired.

The interrupter B is in the form of a pan IOO and is mounted on the ridge A2 and e'Xtends at its rear or discharge end preferably toa point yabout midway between the line of the shaft C and the rear end of the pan A, as best shown in Figs. 2 and 5, the space between the discharge end b of the interrupter and the rear end of the pan A permitting the vfree discharge of the carbid from the said interrupter to the pan as will be understood from the drawings.

The troughs A4 are rounded as shown in Figs. 4 and 5, or they may be angular, if desired as illustrated in Fig. 8, in which the pan 1 has its troughs 2 formed at their bottoms in angular shape and the interrupter 3 is similarly formed at 4.

The division or separation of the discharge pan into two compartments is useful, as it separates or scatters the carbid before it strikes the water, increases the capacity of the device, and renders it mo're reliable and rapid in action. It also causes the carbid to clean. the pan because the motion of the carbid, in feeding, is concentratedin the center of the bottom of the pan where the dirt and slackcarbid would also be precipitated.

. As shown in Fig. 2, and as will be understood from Fig. 1, the discharge spout D is provided with openings d, and the shaft C eX- tends transversely through thesaid feed spout extending through the openings d.

When the feed pan is in the charging position as shown in Fig. l, the cut-0H or interrupter is shifted from below the hopper spout and the pan is adjusted to position to receive and retain its charge of carbid. Then as the motion is reversedv and the feeder swings -towardits discharging position, as shown in Fig. 2, the cuteoif will be gradually interposed below the mouth of the hopper spout, thus interrupting the flow of carbid from the hopper while the pan is discharging its carbid to the water in the generator. When properly proportioned to the size generator it is to feed, the improved device will drop approximately auniform amount of carbid at; each operation.

lIt will be understood that in practice the feeder may be made of malleable casting or of pressed sheet metal, and it may be desirable in some instances to make them of pressed and enameled ware;

We claim- 1. The improved carbid feeder herein described, consisting of a pan having a side plate and a bottom plate secured at its outer edges thereto andbent forming separate discharge troughs, and a ridge between the same, an interrupter or cut-off mounted on the said ridge and discharging at one end to the pan at the opposite end thereof from the discharge of its separate troughs, braces between the pan and interrupter, and brackets secured to the interrupter and having collars .to receive an operating shaft, all substantially as and for the kpurposesset forth.-

2. A carbid feeder yhaving a main discharge pan divided longitudinally into separate independent discharging troughs. L.

3. A carbid feeder having a main discharge pan whose bottom is divided longitudinally into independently discharging troughs, and an interrupter pan or cut-0H above the main pan and discharging to the rear ends of said independent troughs of the main pan. 4. A carbid feeder having a main pan whose bottom is divided by a longitudinal ridge into separate independently discharging troughs opening at one end of said pan, and an interrrupter or cut-off pan mounted on the said ridge and discharging to the mainv an in a direction the reverse of the discharge rom the independent troughs, substantially as set forth.

5. A carbid feeder having a mainpan arranged to discharge at one end, a cut-off or interrupter pan above the main pan and discharging in a reverse direction to saidpan, said interrupter pan being supported ,midway between its sides on the main pan, brackets between the interrupter pan and the sides of the main pan, a shaft and collars connected with the interrupter pan and fitting said shaft, substantially as set forth.
