Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed June 25, 1914. Serial No. 847,352.

To all whom it may concern Be it known that we, JAMES A. SKINNER and HAROLD D. THOMAS, citizens of the United States, residing at East Orange, in the county of Essex and State of New Jersey, and at Bloomfield, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Valve Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates, generally, to improvements in shut-0E valve mechanism; and the invention has reference, more particularly, to a novel valve mechanism for controlling the flow of a plurality of fluids or gases through supply pipes or conduits.

Tue present invention has for its principal object to provide a novel and simple construction of valve mechanism adapted for use in blow pipes or torches for turning on and off the supply of air and gas passing thiough the supply pipes to the burner or torch, together with a novel valve operating mechanism whereby the opening and closing of the valve is easily and quickly accompli hed.

Another object of the present invention is to provide in connection with said valve mechanism by-pass ports through which, when the valve mechanism is shut ofi or closed, a very small volume of gas is permitted to pass therethrough for the purpose of supplying a pilot or ignition flame at the burner or torch when not in use, so that the same will be immediately and automatically ignited when the valve mechanism is turned on or opened.

Another object of the present invention is to provide in connection with said valve mechanism an adjustment means whereby the lay-pass ports may be adjusted therethrough to the pilot or ignition flame of the burner or torch.

Still another object of the present invention is to provide a novel means for mounting and supporting said valve mechanism so that the same may be readily attached to a work-bench or other place at which the blowpipe or torch is desired to be used.

Other objects of the present invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the said invention.

With the various objects of the present invention in view, the said invention consists, primarily, in the novel valve mechanism hereinafter more fully set forth, and the said invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described, and then finally embodied in the claims which are appended to this specification, and which form an essential part thereof.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the novel valve mechanism made according to and embodying the principles of the present invention, the mechanism being illustrated therein operated to its opened or turned on position; Fig. 2 is a similar side elevation of the novel valve mechanism operated to its closed or shut off position. Fig. 3 is an elevation of the opposite side of said novel valve mechanism. Fig. 4 is a detail horizontal cross section taken on line M in said Fig. 1, looking in the direction of the arrow 00, said view being drawn on an enlarged scale. Fig. 5 is a detail vertical cross section taken on line 55 in Fig. 3 looking in the direction of the arrow 3 said view being also drawn on an enlarged scale. Fig. 6 is a detail transverse section taken on line 66 in said Fig. 4, looking in the direction of the arow z; and Fig. 7 is a detail horizontal cross section taken on line 7 -7 in said Fig. 6 looking downward. Fig. 8 is a similar transverse section to that shown in Fig. 6, but illustrating the valve mechanism in its closed or shut off position; and Fig. 9 is a detail horizontal cross section taken on line 99 in Fig. 8 looking downward.

Similar characters of reference are employed in all of the hereinabove described views to indicate corresponding parts.

Referring now to the said drawings, the :refereIlCQ charaoter 1 indicates the complete novel valve mechanism made according to and embodying the principles of our present invention, the same comprising a suitable frame-member 2, the base 3 of which is adapted to be supported upon the edge of a work-bench, table or other suitable location as indicated at 4, and extending downwardly from said frame-member 2 and integrally formed therewith is an armor extension 5, at the lower free end of which is a forwardly extending bracket-piece 6, the latter being provided with an interiorly screw-threaded opening in which is arranged a clamp-screw.

ously modified when so desired, hence we do not limit ourselves to the exact construction of frame-member herein described and illustrated in the accompanying drawings. Preferably said frame-member 2 is provided with a depressed portion 9, said depressed portion being provided with an opening 10.

V Secured to the outerface 11 of said frame- 3 member 2 is a stationary valve-plate 12, the

7 21 to which is attached an air supply hose 22' same having suitably located perforated ears or lugs 13 through which pass fastening screws 14 which screw into said frame-memher 2 and serve, to secure said stationary valve-plate 12 in proper fixed andsupported relation to said frame-member. Said stationary valve-plate 12 is provided on its inner sidewith a hub or boss 15 which is inserted through said opening 10 of said depressed portion 9 of said frame-member. The surface of said hub or boss 15 is prepared to provide a ground or smooth hearing surface 16. The'outer face of said stationary valve-plate 12 is provided with integrally formed and oppositely projecting socket-

portions

17 and 18 the same being each provided with their respective sockets 19 and 20, the former serving to secure an outwardly projecting tubular coupling-pipe leading from the source of air supply, and

the latter serving, in like manner, to secure an outwardly projecting tubular couplingpipe 23 to which is attached an air conveying hose 24 leading to the air jet of the burner or torch of a blow-pipe or similar apparatus. Formed in said stationary valveplate 12 is an air intake port 25, the mouth of which terminates at the ground surface 16 of said hub or boss 15, and the inner end of which communicates with said socket 19. In like manner, formed in said stationary valve-plate 12 is an air outlet port 26, the

, similar apparatus.

extending from the circumference tary valve-plate,

28 the same being each provided with their

respective sockets

29 and 30, the former serving to secure an outwardly projecting tubular coupling pipe 31 to which is attached a gas supply hose 32 leading from the source of gas supply, and the latter serving, in like manner, to secure an outwardly projecting tubular coupling pipe 33 to which it attached a gas conveying hose 34 leading to the gas jet of the burner or torch of a blow-pipe or I Formed in said stationary valve-plate 12 is a gas intake port '35,

the mouth of which terminates at the ground or boss 15, and the surface 16 of saidhub inner end of which communicates with said socket 29. In like manner, formed in said stationary valve-plate 12 is a gas outlet port 36, the mouth of which terminates at the ground surface 16 of said hub or boss 15,

and the inner end of which communicates with said socket 30. Communicating with the mouth of said gas intake port 35, and thereof, is a bypass channel or groove 37 formed in said ground surface 16 of said hub or boss15. V

The reference character 38 indicates a rothe inner side of which is dressed or machined to provide-a ground or smooth surface 39 adapted to be registered against said ground surface 16 of the boss or hub 15 ofsaid stationary valve-plate 12 so as to slide thereupon. The reference char acter 40 indicates a screw or equivalent device 7 connected with said valve-plate 12, the same forming a journal upon which said rotary valve-plate 38 is rotatably mounted. Said rotary valve plate is provided with a suitably located connecting air channel or groove 41 formed stationary in said ground surface 39, which, when 7 said rotary valve-plate is in normal position registers with or straddles the mouths of, said air intake port 25, and air outletport 26 of said stationary valve-plate 12, sofas to permit the air to flow from the former into and through the latter, and thence to the air jet of the burner or torch of the blow-pipe or similar device. In like manner, said'rotary valve-plate is further provided with a suitably located connecting gas channel or groove 42 formed in said ground surface 39, which, when said rotary valve-plate is innormal position registers with or straddles the mouths of said gas in-. take port 35 and gas outlet port 36 of said stationary valve-plate 12, so as to permit the gas to flow in full volume from the former necting air channel or groovetl are oscillated out vof registration with the respective gas ports and air ports of said stationary valve-plate 12, therefore preventing the flow of the full volume of gas from the gas intake port to and through the gas outlet port, and the flow of air from the air intake port to and through the air outlet port. In order to provide, however, for the flow of a minimum volume of gas, even when the rotary valveplate 38 is moved to shut-off position, the ground surface of the same is provided with a suitably located by-pass channel or groove 43 extending circumferentially from one end of said connecting gas channel or groove 42, which, when said rotary valve-plate is oscillated to shut-ofi position, registers with said by-pass channel or groove 37 formed in said stationary valve-plate 12 and leading from said gas intake port 35, so that a small volume of gas is permitted to flow from said gas intake port through said registered by-pass channels or

grooves

37 and 43 into said connecting gas channel or groove 42 and thence through said gas outlet port 36, so that a small quantiy ofgas flows continuously to supply a pilot light at the gas jet of the burner or torch of the blow-pipe or similar apparatus.

in Figs. 6 and 7 the rotary valve-plate 38 is illustrated in its open or turned on position, while in Figs. 8 and 9 the rotary valve-plate 38 is illustrated in its shut-0d position, and the operative arrangement and position of said respective by-pass channels or grooves 37 and as is illustrated so as to be clearly understood from an inspection of said figures of the drawings.

The means for operating said rotary valve-plate 38 comprises a lever-arm a l which is pivoted upon a journal-stud as suitably located and connected with said frame-member 2. Said lever-arm 4% is proided with an extension portion 16 ha ing a downwardly and inwardly inclined portion d7, projecting inwardly from which is a pin or lug 4:8. Said rotary valve-plate 38 is provided with an outwardly or radially extending arm or projecting portion 19, which is provided in its periphery with a receiving slot adapted to rece've said pin or lug 48 whereby the movement of said lever-armed and the ports connected therewith is transmitted to said rotary valveplate 38. Said flan e 8 of said frame-member 52 is provided with a stop-boss 51 against which the free end of said extension portion 4:6 is stopped to limit the upward movement of said lever-arm A l. Connected between said lever-arm at and said flange 8 of said frame-member 2 is a pull-spring 52 which serves to maintain and retain said lever-arm ad in normal position as stopped by said stopboss 51. When said lever-arm A is in its normal position, as above described, it serves to move or rotate said rotary valveplate to its open or turned on position, so that its respective connecting channels or grooves register with the respective air and gas ports of the stationary valve-plate 12, thereby permitting the flow of a full volume of both air and gas to the blowpipe burner or torch. when said lever-arm as is pressed or swung downward it serves to rotate said rotary valve=plate 38 to its closed or shut 01? position, so that its respective connecting channels or grooves are carried out of registration with the respective air and gas ports of the stationary valve-plate 12, thereby shutting oi? the flow of air, and shutting off the flow of gas except such as is permitted to pass through the by-pass grooves or channels for the purpose of supplying fuel to the pilot light or flame of the blowpipe burner or torch. The reference character 53 indicates a suitably located adjustable stop-screw which is connected with the flange 8 of said frame-member 2, and against which the arm or projecting portion i9 of said rotary valve-plate 38 is carried when operated by said lever-arrn A and moved to its shut off or closed position. By regulating the position of said stop-screw the rotary valve-plate 38 may be stopped to enlarge or decrease the opening or passage formed by the registered bysass channels or grooves of the rotary valve-plate and stationary valve-plate, whereby more or less gas may be permitted to bypass or flow to the burner or torch of the blowpipe. A lock-nut 54: may be associated with said stop-screw to secure the same in any desired adjusted position. Suitably secured to the free end oi said leverarm 44 is a hook-member 55, and when the burner or torch of the blowpipe is not use the same is hung upon said hook-member 55, whereupon its weight tends to more downward and hold down said lever-arm at? whereby said rotary valve-plate 38 is moved to and maintained in its closed or shut ofi' position as above described.

The operation and advz-mtages of the above described invention will be understood from the above description and inspection of the accompanying drawings, without further explanation.
