CARBURETING' APPARATUS.
SPECIFICATION forming part of Letters Patent No. 731,137, dated June 16, 1903.
i Application filed December 8, 1902. Serial No. 134,253. (No model.)
resident of the city of St. Louis and State ofv Missouri, have invented certain new and useful Improvements in Carbureting Apparatus,`
of which the following is a specification. I
The present invention relates to that class of gas apparatus in which a supply of air is carbureted and supplied to the usual burners for illuminating and heating purposes, and has for its object to provide a simple, durable, and ecient apparatus in which the various operations of the different parts areautomatically and interdependently controlled to meet the varyingdemands upon the apparatus and regardless of such variations inthe demand to at all times afford a supply of combustible gas at the required degree of carburization, all as will hereinafter more fully appear, and be more particularly pointed out in the claims. v
In the accompanying drawings, illustrative of the present invention, Figure 1 is a vertical sectional elevation of an automatic gas apparatus embodying the presentinvention 5 Fig. 2, a detail side elevation of the air-pump, airstorage chamber, and the automatic controlling mechanisms of the same; Fig. 3, an enlarged detail of the combined filling and relief valve of the present apparatus; Fig. 4, an enlarged detail section of Avalve controlling the circulation'of the gasolene or other hydrocarbon iiuid in the carbureter.
Similar numerals of reference indicate like parts in the several views.
Referring to the drawings, 1 represents a.
closed vessel constituting the carburetingchamber and which in the present construction is divided by perforated horizontal diaphragms into a lower gasolene containing chamber 2, a carbureting-chamber 3, containing the usual loose fibrous lling, and an upper receiving-chamber 4 for the storage of the carburetedair. A
5 is the lling-pipe, extending up vertically from the top of the carbureting-chamber and provided at its upper end with a filling-funnel Or other equivalent device.
6 is a vent-pipe extending vertically from the top of the carbureting-chamber in parallel relation to the Afilling-pipe 5, as shown.
7 is a duplex valve arranged at the vupper ends of the respective pipes 4 and 6 and adapted to simultaneously open the passages in saidpipes inthe operation of introducing a supply of gasolene into the interior of the carbureting-chamber and to close said passages after such filling of gasolene has been introduced.
8 is an operating-handle by which the duplex valve 7 is manipulated.
' 9 is a circulating-pipe the lower end of which dips into the body of liquid gasolene in the' lower chamber 2 and at its upperend is connected to the perforated upper diaphragm ofthe carbu reting-chamber, asshowri in Fig. 1.
10 is a valve-chamber arranged in the pipe 9 and provided with upper and lower check- -valves 11 and 12, as shown in Fig. 4 of the drawings. The arrangement is such as to impose upon the gasolene passing through such pipe an upward movement from the inlet end of the pipe in lower chamber 2 of the carbureter to the outlet end of such pipe at the perforated upper diaphragm of said chamber and so that there will be no reflux of the gasolene through the pipe 9.
13 is a pipe connected at one end to the single-acting reciprocating pump,hereinafter described, and at the other end to the valvechamber 10 at a point intermediate of the check-valves 11 and 12, as shown in Fig. 4.
14 is an enlargement in the pipe 13 afljacent to its connection to the circulationpipe 9 and which may be formed by an enlarged header inserted in the pipe 13 or by any other well-known formation.
15 is a single-acting reciprocating pump operated in any usual manner, but preferably in the automatic and interdependent manner hereinafter described, and having the closed end of its piston-barrel connected to the pipe 13, as heretofore set forth.
With the described arrangement of parts and with an upstroke of the piston of the pump 15 gasolene in the lower chamber 2 of thecarbureter is drawn up in the lower portion of the circulating-pipe 9, past the lower IOO check-valve 12, and into the local collectingchamber or receiver, formed by the enlargement 14 of the pipe 13, as before described. Such storage-chamber in the present invention is of a capacity approximating that of the pump-barrel of the pump 15, and by its use all danger or liability to the passage of any gasolene into the pump-barrel and a dangerous leakage therefrom are avoided in a very simple and efficient manner. With a downstroke of the piston of the pump 15 the gasolene above the lower check-valve 12 and that contained in the storage-chamber of the enlargement 14is forced past the upper checkvalve 11 and through the upper part of the circulating-pipe 9 to be discharged upon the fibrous filling of the carbureting-chamber 3 to saturate the same.
16 is the outlet-pipe from the carbureter and which is adapted to conduct the carbureted air to the point at which it is to be used.
17 is the inlet-pipe of the carbureter and through which a supply of air under pressure is introduced into the interior of the carbureter from any usual and suitable'source, preferably from ther automatic air compressor, now to be described, and which constitutes the subject-matter of a companion application for Letters Paten t, SerialNo.134,252, filed December 8, 1902. Such automatic aircompressor comprises the following construction and arrangement of parts:
18 isan aerometer of any usual construction and having the usual inverted-bell receiver 19, adapted to rise and fall in a Water seal formed in the fixed portion of the structure, as usual in the present type of apparatus and as shown in Fig. 2 of the drawings. To the interior of such receiver' 19 is connected by suitable pipe connection the inletpipe 17, heretofore described, of the carbureter.
2O is the air compressor or pump, which in the preferred form of the present apparatus consists of a stationary open-topped tank, the vertical walls of which are partitioned off to form the annular chamber or Water seal 21 for the movable piston of the pump or compressor.
22 is an inverted-bell piston, the annular depending skirt of which dips into the annular water seal 2l aforesaid, the described construction affording a closed central air-compression chamber 23, the capacity of which is-alternately increased and diminished by the alternate up and down strokes of the bellpiston 22 to alternately draw in air from the outer atmosphere and compress and force said air into the aerometer or storage-chamber 18.
24.- is an inlet-pipe provided with a checkvalve 25 and adapted to admit air into the compression-chamber 23.
26 is a pipe connected between the air-compression chamber 23 and the interior of the aerometer or storage-chamber 18. 27 is a check-valve in said pipe 26 for preventing a retrograde movement of the air through such pipe.
28 is a single-acting reciprocating waterengine arranged Within the air-compression chamber 23 aforesaid, with its piston-rod 29 connected to the bell-piston 22 and adapted to impose reciprocating movement upon the same. apparatus the single acting reciprocating pump 15, heretofore referred to, is also arranged within the compression-chamber 23 and in parallel and adjacent relation to the Water-engine 28, and the piston-rod of such pump is connected to the bell-piston 22 of the air-compressor, so as to move in unison with the piston-rod of said water-engine to cause the heretofore-described circulation of gasolene only when the water-engine and air-compressor are in active operation. The advantages resulting from the described location of the water-engine and gasolene-pump are that any leakage from either of such mechanisms is retained Within the air-compression chamber 23 and collected in the bottom portion of the same to be removed as required by a suitable drain or blow-off appliance.
29 is the inlet-outlet pipe of the Water-engine 2S, connected at one end to the under side of the cylinder of said engine and at the other end to the casing of the reversing-valve of said engine.
30 is the casing of the reversing-valve of the Water-engine 28, which may be of any usual and suitable construction, but whichis preferably of the piston type of valve set forth in my companion application for Letters Patent.
31 is a trip-lever pivoted on a fixed bracket. One end of such lever is in operative engagement with the stem 32 of the reversing-valve aforesaid, While the other end is weighted to counterbalance the weight of said valve.
33 is a Weighted overbalance-arm pivoted at its lower end on the bracket aforesaid in common with the trip-lever 31 and adapted to have limited independent movement with relation to such trip-lever. Such amount ot' independent movement will be in excess of that required to move the arm 33 from the position shown in Fig. 2 to a position past a vertical line, so that said arm will fall by gravity into an opposite position, and the construction is such that as said arm nears the end of its falling movement it will engage the trip-lever 31 to cause a movement of reversal of the reversing-valve of the Water-engine and to which said trip-lever is operatively connected. A corresponding operation of the parts will take place in the reverse direction in the'neXt succeeding operation of the described valve-operating mechanism.
34 is a vertical rod secured at its upper end to the bell-piston 22, and such rod is suitably guided on the fixed exterior of the air-co1n In the preferred form of the present IOO IIO
pressor, so as to be confined to vertical movement.
35 is a projecting hub near the lower end of the rod 34, which in the final downward movement of thebell-piston 22 is adapted to engage a laterally-projecting extension on the oVerbalance-arm 33 and impart the initial movement above described.
3G is a slack connection or chain connecting the lower end of the rod 34 with the overbalance-arm 33 and adapted in the nal upward movement of the bell-piston 22 to lift the oVerbalance-arm 33 upward and pasta vertical line, so that said arm will drop by gravity in an opposite direction to that before described and in its descent again reverse the position of the reversing-valve of the water-engine to cause a fresh reciprocation of the same. At other times the chain connection 36- hangs loose to permit of the hist-mentioned operation taking place without hindrance.
37 is a pipe extending vertically up from the outlet or waste passage of the reversingvalve of the water-engine and is adapted to discharge the waste water from such engine into the annular chamber or Water seal 2l to preserve a predetermined height of water in the same.
3S is a drain or overliow pipe connected to the upper end of the annular chamber or Water seal 21 and adapted to carry away the surplus water discharged into said seal by the pipe 37.
39 is an equalizing-pipe connecting the upper ends of the annularchamber or water seals of the air-compressor 20 and the aerometer 18, so that a uniform level of Water will prevail in both.
40 is a cut-off valve in the supply-pipe 41, by which water or other motive fluid is supplied under pressure to the reversing-valve of the Water-engine 28. 42 is an operatinglever for such valve, having link connection 43 with the bell-receiver 19, as shown. The arrangement is such that with such bell-receiver reaching a predetermined elevation motive fluid will be cut ol from the waterengine 2S, so as to cause a stoppage of the aircompressor until by a Withdrawal of air from the storage-tank of which the bell-receiver 19 forms a part the said bell-receiver is allowed to descend from such point of predetermined elevation, when the valve 40 will be again opened to cause a fresh operation of the aircompressor. 44 is a second cut-olf valve arranged in said Watersupply pipe 41 and which is provided with a weighted operatingarm 45, which is normally held in an elevated position and with the valve 44in an open condition, said arm being maintained in such position by a spring catch'or support 46.
47 is a push-rod carried by the bell-receiver 19 and provided with a pivoted spring-toe 48, moving in vertical alinement with the weighted end of the operating-arm 45 and adapted ina downward movement of said push-rod to push such operating-arm from the supporting engagement of the spring catch or support 46 to enable such weighted arm to fall by gravity andl effect a closing movement of the cut-off valve 44 and prevent the further operation of the water-engine 23. The arrangement of the parts is such that with a rapid evacuation of the air from the carbureter and storage-tank due to the accidental breakage of any of the main carbureted-airsupply pipes within the building the descent of the bell-receiver 19 to its lowermost position will effect the described release of the weighted valve-operating arm 45 to stop the further pumping of air into the storage-chamber and, what is of much greater importance, the continued discharge of the combustible vapor into the building through the described break in the main supply-pipes of such building. After such automatic and safety operation of the Weighted operating-arm 45 it is intended that the same must be restored by hand to its normal position in engagement with the support 46, and this can be readily done by swinging the pivoted spring-toe 4S to one side during such manual movement of said arm. A

' 1. In a carbureter of the type herein described, the combination of a carbureterchamber provided with the usual air-inlet, carbureted-air outlet and loose porous filling, a circulation-pipe extending from the bottom of said chamber to a point adjacent to the upper surface of the porous filling in said chamber, a valve imposing movement in an upward direction to fluid passing through said pipe, a local collecting-chamber connected to said pipe, and a single-acting pump having pipe connection with said local collectingchamber, substantially as set forth.
