PACIFIQUE CHRAZ, 0F WIDNOON, PENNSYLVANIA.

ACETYLENE-GENERATOR.

Application filed August 2. 1912.

To all lwhom it may concern.'

Be it known that I, PACIFIQUE CrIRAZ, a citizen of the United States, residing at lVidnoon, in the county of Armstrong, State of Pennsylvania, have invented certain new and useful Improvements in AcetylenesGencraters; and I 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.

This invention relates to new and useful improvements in lanterns and more particularly to hand lanterns of the acetylene type burning acetylene gas and which are so constructed that they cannot be blo-wn out by the wind and so that the possibility of smoking or danger of tire is reduced to a mm1- mum.

`With the above and other objects in view, the invention consists of certain other co1 nbinations and arrangements of parts as will be hereinafter more fully described7 claimed and illustrated in the accompanying drawings, in which:

Figure l is a side elevation of my improved lantern. Fig. 2 is a top plan .View thereof. Fig. 3 is a central vertical sectional view. Fig. 4 is a horizontal sectional view taken on the line eil-4; of Fig. 8. Fig. 5 1s a bottom plan view of the acetylene burner reservoir removed from the base. Fig. 6 1s a detail view of a joint connecting the latter parts. t

Referring to the drawings 1n detail, my improved carbid or acetylene gas lantern comprises a base or ring support 10 to which the lower extremities of supporting legs l1 are attached at equi-distantly spaced points while the upper ends of the legs are attached to an intermediate supporting band 12 adapted to encircle a cylinder 13. This cylinder 18 in turn serves for the attachment of a main bail 14 having the lower extremities of its side portions bent to form hooks l5 which are pivotally engaged with the cylinder near its top portion. The cylinder is thus swingingly supported by the bail `and it will be observed that the bail comprises a single section of wire bent at right angles at two points to form eyes 16 receiving the lower extremities of a relatively circular handle bail 17 which are pivotally connected therethrough to allow swinging movement of the main bail relative thereto. The cylinder' is also provided with a reduced collar 18 Specification of Letters Patent.

having an inwardly extended bottom tlange lf) adapted to receive and support respec tively, the rim portion of a transparent globe Q0 which is received between the side portions of the main bail and is held from upward displacement by a cross wire or retaining member 9.1 having its ends formed with coils 22 slidable on the guide forming side portions of the main bail and held downwardly displaced by coiled springs Q3 mounted on said side portions between the connecting portion of the main bail and washer plates Q4; connected to the coils Q2. lt will of course be understood that the springs tend to exert downward pressure on the retaining member to engage the upper end of the globe and thus prevent vertical or lateral displacement thereof.

rllhe lamp further embodies a water tank or reservoir Q5 formed at its lower end with an enlarged tlanged rim 26 having diametrically oppositely disposed slotted plates 27 formed with outwardly bent or bayonet portions 2S for engagement by similarly disposed pins 29 carried by the cylinder 13 when the latter is engaged within the .flange of the rim so that said parts are secured together and the gas generating apparatus is supported by the -trame. The tank 25 is formed with a reduced centrally disposed and internally threaded bottom portion 30 receiving the reduced externally threaded neck 31 of a carbid reservoir or holder 3Q which is provided with an interposed packing ring 38 rendering the joint air tight to prevent the escape of gas generated in the holder and which escapes throllgh a central vertical supply tube 341; to the burner tip 35. The. water tank is provided with a screw cap 3G for supplying water thereto and the feeding of the water to the carbid is regulated by a valve stem 37 carrying a metallic plate 38 and compression valve 39 for closing against a supply tube .l-O depending from the bottom of the tank into the carbid holder at one side thereof. lt will also be observed that the stem extends through the tube l() and depends therebeneath to form a drip feed for the water. In order to regulate the supply of the water. the upper end o'l the stem carries a pinion L.ll and a threaded enlargement 42 therebeneath engaged with a threaded extension 4S of the tank so that the valve. is moved vertically by means of rotation imparted to a tube-ineloscd shaft 44 mounted on one side of the tank and having a pinion 45 at its upper end in mesh with the pinion 4l and capable of being conveniently rotated by a small lever or crank handle 46 secured to the lower end of the shaft beneath the flanged rim. This last named construction permits convenient control of the burner without removing the globe or frame.

From the foregoing description in connection with the accompanying drawings, it will be seen that besides providing a lantern and frame construction which will prevent the same from blowing out and reduce the liability or' smoke and lire, the parts are so assembled as to permit the same to be rigidly connected and readily taken apart for cleaning but still constructed to durably serve the rough usage to which a device of this character is generally put.

I claim:

In an acetylene generator, a tank having an upwardly depressed button forming a socket provided with screw threads, a carbid receptacle having a screw threaded neck litting in said socket, a gas tube projecting through said tank and communicating with said receptacle, a valve stem parallel with said tube and having a valve controlling a port that establishes communication between said tank and said receptacle, a stub shaft parallel with said stem, a bearing on said tank housing said sha-ft, meshing gears connecting the upper ends of said shaft and said stem above the top of said tank, and a crank handle fixed to the lower end of said shaft for rotating said shaft in either direction with a resultant actuation of said valve stem by said gears to open or close said valve.

In testimony whereof, I afl-ix my signature, in presence of two witnesses.
