FEED FOR AGETYLENE-GAS GENERATORS.

Specification of Letters Patent.

Application filed August 6, 1907.

Patented July 13, 1909.

Serial No. 387,368.

To all whom it may concern:

lie it known that we. JUIIN BoLANn and 'umrur A. lllxnnn, citizens of the United States, and residents of Decatur, Macon county, State of Illinois, have invented certain new and useful Improvements in Feeds for Acetylene-Gas Generators; and our preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention is an improvement in acetylene gas generators, and it consists essentiall v in mechanism for delivering the car bid from the holder to the generating chamher in charges at. intervals determined by the consumption of the gas and the consequent descent of the seal cap, or upon movement of any other movable part of the apparatus responsive to changes in pressure of the gas in the generating chamber.

To this end it consists especially in details of construction of the parts more particularly constituting the carbid feed, all as set forth in the following specification and illustrated in the drawings herein.

Figure 1 is a general elevation of the entire machine with the principal parts of the gas generator shown in section; and Figs. 2 and 3 are enlarged side elevations of the seal cap broken away at its lower end, and the basket forming part of the carbid feed shown in greater detail.

Referring to the drawings, the reference numeral 1 designates the wall of the generating chamber whose lower end, it will not be necessary to illustrate for the purposes of-describing the present invention, and the numeral 3 designates a cylindrical carbid holder whose wall 3 has a rim 4 at its upper end which curls outwardly and rests upon the upper end of the chamber 1 and is supported thereby, and said rim has also the open handles 5. Its lower end is open, and from it depend legs or straps 16 16 to a base 16 upon which it can rest when it is removed bodily from the generating chamber. The skeleton base 16 thus provided is of particular advantage in connection with the holder 3, which, as will hereinafter ap pear, is provided with a rocking charge re ceiver and deliverer, which would not permit the holder 3 to stand upright were it not for the provision of the skeleton base 16, which depends below the delivery point of the holder and the charge receiver and deliverer. Internally it is provided with a downwardly converging hopper 3" leading to a central delivery spout (3 whose lower end or mouth preferably stands slightly above the lower end of the cylindrical body 3 as shown in Fig. l. \Vithin the downwardly converging hopper 3 I preferably place a central conical part 3, the purpose of which is to obviate the tendency of the carbid, which is lrvgroseopie. and consequently prone to massing and sticking together, forming a bridge or arch across the hopper and seriously interfering with the feed. The cone :1 elfectually destroys any bridging .across the hopper and insures the feeding of the particles of carbid down around the circum ference of this part 3", as clearly shown in Fig. 1.

The numeral 2 designates the seal cap which fits loosely over the generating chamber 1 and whose lower end rests in a liquid seal in a manner well known in the art and not necessary to illustrate and describe here. Its cover 2 is closed as usual, and it is provided with an inlet opening 2 with removable closure, through which the hopper 3 Within the holder 3 'an be filled from time to time.

The gas passes through suitable pipes and valves not necessary to define in the present application, into a receiving tank whose bell 17 is illustrated herein as provided with an upright rod 16 at its upper end guided in a fixed bracket 18. To said rod at 13 is pivoted the center 13 of a feed lever 12, one end 12 of which has lost motion in its fulcrum by moving between the upper and lower ends of 13 and 13 of a slot in the bracket 18 and the other end 12 of which rests upon the seal cover 2. The rod 11 passes through a tube 11 which extends froin the bottom of the holder to the cross-handles at the top, said tube 11 being flattened or of such size as to allow for play of the rod 11 in its actuating movements. Hence when the bell rises by the accumulation of gas within the receiving tank the lever is raised bodily until its end 12 strikes the upper end 13 of the slot, when its other end 12 is raised oil the seal cover 2. On the other hand, as the bell 17 descends, the center of the lever is depressed until its end 12" strikes the lower end 13 of the slot in the bracket, after which its left end 12 is caused to descend upon the seal cover 2 and pre the latter downward. It is to be understood that the seal cap has vertical movements independent of those of the bell and in addition thereto, but the bell being larger and more powerful in its action, its rise and fall will by lever 12 cause a forcible descent of the seal cover in case the latter should stick in place. In other words, while under normal conditions the bell and the seal cap are adapted for independent movement, nevertheless, by the arrangement just described, an abnormal condition of the parts will resuit in the bell actuating the seal cap in order to correct such abnormal condition.

Coming now more particularly to the present invention, the numeral 7 designates a basket charge receiver and deliverer which we have shown as a tilting or rocking receiver and deliverer which is pivoted at (3 to the spout 6 near its lower end and is open at its upper side so that the spout can deliver thereinto about midway between its ends which latter are closed. The right half of its bottom is closed, and the left half is covered by a gate 9 which is counterbalanced as at 8 and whose shaft or axis 9* extends at right angles and carries a weighted arm 9 adapted to pass over the center 9 and throw the gate to either an open or closed position. The right end of the basket also carries a weight 8 which makes it heavier than the left end, and from the latter projects a rod or pin 10 connected to a rod 11 which passes upwardly through the holder 3 and carries a hook 11 at its upper end adapted to engage with the hook 11 inside the seal cover 2*. The basket 7 is also provided internally with "the transverse partition 7 dividing it into compartments 7 and 7 b which are respectively choke chambers and delivery chambers for the charge receiver, and the partition does not extend quite to the right hand end as best seen in Fig. 8. By preference, this partition also has near its right hand end a depending wing '7 Whose function is to choke the passage around that end of it.

The operation of this much of our improved device is as follows: Carbid being fed in at 2, partially fills the holder 3 as illustrated in Fig. 1, and flows through the hopper and its spout into the basket which stands in the position shown in Fig. 2. Flowing into the chamber 7 the carbid falls uponthe partition and moves to the right thereon around its extremity as shown at 15, past the wing 7 and falls upon the bottom and right hand lower corner of the basket which forms the charge deliverer and receiver,in the position which it occupies at that time,-accumulating there until it sets back around the partitlon and chokes the spout 6 so as to prevent its further flow from the hopper. Any movement, such as the consumption of gas, which causes the descent of the seal cap, thereby depresses the rod the hinge line 9 of the gate 9 has passed the central vertical line marked X, and the weight 9 has been brought up to and finally past the said line until it falls over to the position shown in Fig. 3, and causes the opening of the gate, resulting in the delivery into the water beneath of the accumulated carbid at the right hand end of the basket. As is well known to those falniliarwith devices of this kind, this charge of carbid immediately generates additional acetylene gas which is passed into the receiving tank, and thereby causes the bell 17 to rise. The rise of the bell releases the pressure upon the seal cover 2 of the left end 12 of the feed lever 12, and accumulation of. gas also causes the seal cap 2 to rise. In this movement, the hooks 11 and 11 engage and lift the rod 11, and through the pin 10' finally move the basket to the position shown in Fig. 2. When it reaches that position, the accumulated carbid at 15 of Fig. 3 slides down the partition 7 and around its right hand end, and the operation is repeated. a

If for any reason the seal cap should stick or not work with suiiicient speed, the bell 17 will, through the instrumentality of the feed lever 12, as above described, forcibly cause the descent of the seal cap and the rocking of the basket as just set forth.

Access to the interior of the generating chamber or the holder is obtained by first removing the seal cap entire; and in order to be sure that the gas within the receiving tank shall not, accidentally esca e at this time, we provide a valve 19 in t e pipe between the generating chamber and the tank, and lead a rod 19 therefrom through bearings 20 to a hook l9 at its upper end. The position of the hook is such that it must necessarily be turned aside to permit the removal of the seal cap, and in so turning it the valve 19 is elosedhence a most careless operator could not permit the escape of the accumulated as within the tank.

As best seen in Fig. 2, the shank of the hook 11 which is secured beneath the seal cover 2 stands at its center while the bill of the hook projects radially therefrom. The entire rod 11 rises-from the pin 10 through from its axis, and the bill of the hook 11 at the upper end of this rod projects toward the hook 11", after which it can be lifted out of place. In restoring it to positionit is manipu'lated in a reverse direction as will be understood.

In the generation of the gas caused from the action of the water upon thecarbid there "1s considerable moisture which rises and collects on the under side of the holder.

To prevent this moisture from comin in contact with the carbid contained wlthin the basket 7 and prior to its being fed into the generating chamber, we provide the shields 14 which are made fast to the exterior of the hopper 3 of the holder 3, and extend obliquely outward any given distance beyond both ends of the basket 7, being held more permanently in position by the tie or hinder 14.

Otherwise than as above described, the details of construction are unimportant, and considerable change may be made therein without departing from the spirit of our invention.
