ANSCHICKS, OF CHICAGO, ILLINOIS, ASSIGNOE TO PBOTEC'IOSEAL COM- PANY OF AMERICA, OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS APBARATUS FOR HANDLING- VOLATILE LIQUIDS Application filed January 14, 1927. Serial No. 161,126.

My invention relates broadly to apparatus for handling volatile liquids and particularly to receptacles for handling such liquids.

The invention has among its other objects the production of apparatus of the kind described which' will be convenient, compact,

be obvious to those skilled in the art from the 2,0. disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

In the drawings, I have shown a preferred form of the invention embodied in a receptacle for holding volatile liquids, the receptacle being particularly adapted for use in connection with thawing operations. Thus, the receptacle may be used with advantage to pour volatile liquids upon-railroad frogs or the equivalent, means being carried by the receptacle whereby the liquid may be ignited as it is poured therefrom.

Referring to the drawings, the reference character 10 designates a receptacle or can which is preferably cylindrical and is preferably formed of sheet metal or the equivalent. As best shown in Fig. 3, the can 10 comprises a flanged bottom 12 rigidly secured to the lower end of a cylindrical wall 13 which is closed at its upper end by a flanged cover 14. The cover 14; is secured, in this instance, by' rivets 15 to the cylindrical wall 13. Formed in the cover 14: is' a filling opening 17 in which an annulus 18 is soldered, and screw threaded into the annulus is an annular member 19 provided with an inwardly extending annular flange 21 having a plurality of apertures 22 formed therein. The annular member 19-is also provided with an integral downwardly extending flange 24 into which a ring 25 is screw threaded and soldered to the ring 25 is a tubular member 27 which is preferably formed ofv wire mesh or perforated sheet metal, theconstruction being such that the apertures through the mesh or perforated metal are flame proof. The lower end of the tubular member 27 is closed by a disc '28 which supports the lower end ofa perforated tubular member 29 disposed within thetubular member 27. The proportions of the tubular members are such that there is an annular space between the cylindrical walls thereof. It will be noted that this annular space communicates with the openings 22 provided in the flange 21 and that the upper end of the tubular member 29 projects into an annular groove 30 provided inthe flange 21. The" upper surface of the. annular member 19 is preferably provided with anannular groove 32 in which an annular flange 34: provided upon a cover 35 seats, the cover 35 being pivoted by a pin 36 to a lever 37 which is pivoted upon a pin 38 carried by lugs 39 which are formed: integral with he annular member 19.-

A spring wound around the pin 38 yieldingly holds the lever 37 in a position wherein it in turn holds the cover 35 in its closed position.

Projecting downwardly from the cover 35 is an inte ral boss 42 having a relatively large bore 43 in the lower end thereof, which bore 43 may communicate with a smaller bore 44 formed in the boss. The boss 42 is provided with a valve seat 46 intermediate the bores 43 and 44, the valve seat 46 being engageable by a ball valve 48 which is yieldingly urged into engagement with the seat by a compression spring 50 interposed between the valve and a cap member 52 screw threaded into the bore 43. It will be noted that the cap member 52 is provided with an aperture 53. The arrangement is such that when the pressure obtaining within the receptacle is less than atmospheric pressure, the atmospheric pres sure will unseat the valve 48 and air will enter the receptacle through'the bores 44 and 43 and the aperture 53.

It is readily understood that the cover 35 may be quickly brought into its opened position when the receptacle is to be refilled and that when liquid is poured into the tubular member 29, air may pass up through these annular spaces between the tubular members 27 and 29 to the openings 22 and then pass from the receptacle. This, of course, facilitates the filling operation.

The receptacle is preferably provided with two handles designated by the reference characters 55 and 56 which are preferably formed from a strip of metal bent in the manner best shown in Fig. 3. It will be noted that the handle 55 is disposed above the re ceptacle and that it is reinforced by sheet metal members 57 in the corners thereof. The handle 56 is disposed adjacent the cylindrical walls 13 and is r'eenforced by a stamped sheet metal member 59.

As best shown in Fig. 3, the cylindrical wall 13 is provided with an opening 60 adj acent the lower end thereof, in which opening 60 an annulus 61 is soldered, the annulus 61 preferably comprising atubular portion 63 which projects through the opening 60 and is screw threaded to receive the nut 64 and one end of a valve fitting 67. The passage eX- tending through the annular member 61 and its tubular portions 63 communicates with a passage 68 which extendsthrough the valve fitting 67, and is controlled by a rotary valve 69. The valve 69 is rigidly secured to the lower end of a tubular valve stem 70 which is preferably substantially rectangular in cross section. The upper end of the tubular valve stem 7 0 is preferably rotatably journaled in a bearing member 72 soldered or otherwise secured to the outer surface of the cylindrical wall 13. Rigidly secured to the upper end of the tubular valve stem 7 0 is a lever 73 which may be angularly displaced to bring the valve 69-into its opened and closed positions. The construction described is advantageous in that the lever 73 is readily accessible and is also positioned so that there is very little chance that it will be displaced accidentally when used around piles of snow or other material.

Screw threaded into the valve fitting 67 and communicating with passages 68 is a relatively long tube or pipe 7 5 which, at its outer end, has a collar 76 screw threaded thereon, the collar 7 6 forms part of a nozzle 77 which also comprises a tube 78 screw threaded into the collar 76. The tube 78 is provided with a plurality of relatively large apertures 80 and the outer end of the tube 78 is closed by a perforate end wall 81, the perforations being designated by the reference character 82 and being of such size that they are flame proof. In the illustrated embodlment of the invention, the wall 81 is preferably formed integral with or rigidly secured to a tubular member 84 which encircles the tube 78, and is provided with a plurality of flame proof apertures 82. To prevent the tubular member 84 from being withdrawn from the tube 78 the end portion of the tubular member 84 is preferably pressed into an annular groove 87 formed in the tube 78. Disposed around the tube 78 and the tubular member 84 is a substantially cylindrical shell 87 which extends from the end wall 81 to a shoulder 88 formed upon the collar 76, the shell 87 being screw threaded upon the collar. The shell 87 is provided with a plurality of relatively large apertures 90 and it will be noted that the shell is of such diameter that it forms an annular space 92 between it and the tubular member 78. This space is preferably filled with asbestos 94 or the equivalent, which asbestos serves as a wick during the thawing operations.

Means is preferably provided for tying the pipe 75 intermediate its ends to the receptacle so that the device will not be injured when the nozzle 77 is brought sharply into contact with a rail, a tie or the like. The reinforcing means preferably comprises a V-shaped bar 97 having a square cross-section, the apex of which passes through an eye 98 formed upon a clamping member 99 secured to the pipe 7 5 intermediate its ends. The ends of the V-shaped bar 97 project into tubes 100 and are retained therein bycopper pins 101, the tubes 100 being riveted or otherwise socured to the cylindrical wall 13. It will be noted that the clamping member 99 is provided with a bolt 103 and a nut 104 so that it may be quickly secured in any desired position upon the pipe.

The operation of the above described apparatus is substantially as follows: The receptacle 10 may be filled at any time through the tubular member 29 ifthe cover'35 is first brought into itsopened position. When the any undesirable rise in pressure in the re-' ceptacle will be relieved as the spring 40 is so designed that it will permit the cover 35 to be unseated by the excess pressure. Of course, the cover 85 will seat immediately after the pressure in the receptacle is restored to normal. Assuming that the receptacle has been filled with gasoline or the equivalent and that the device is to be used to thaw a railroad frog or switch, the lever 73 is manipulated to open the valve 69 so that the volatile liquid may flow through the pipe 75 and saturate the asbestos or other packing 9- -1. The vapor of the volatile liquid will then pass through the apertures 90 provided in the shell 87 and may be ignited by any suitable means. The receptacle is then held by means of its handle 56 in such a position that the volatile liquid will flow upon the frog or switch through the tube 7 5 and the apertures 82 provided in the nozzle 77. The liquid portion from the apertures 82 will be ignited from the flame surrounding the shell 87 and will continue to burn when it strikes the elements to be thawed.

After the thawing operation has been completed, the supply of liquid to the pipe 7 5 is cut off by manipulating the lever 73 to close the valve 69. The flame will be extinguished gradually, but it will not flash back into the pipe 7 5 because of the flame proof apertures and 82.

The perforate tubular member 27 Prevents the propagation of flame within the receptacle. Thus, if the cover 35 is opened and gases escaping from the receptacle are ignited, the flame can not pass through the apertures in the member 29 to ignite the gases and liquid within the receptacle.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction arrangement and combination of parts here in shown and described, or uses mentioned.
