To all whom it may concern.

Be 'it known that I, JOHN Pn'rnnson, a citizen of the United States, residing at Maywood, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in 'Torch-Supported Ladles, of which the following is a specification.

The present invention relates to ladles for service as attachments to torches which emit a heating flame against the bowl of the ladle. One object of the invention is to so construct and mount the ladle that the flame will be emitted against the lower part of the bowl where the solder or other contents must lie. To this end the support for the ladle lies above the outlet of the torch and the axis of the emitted flame extends in a direction parallel to and below the supporting element which connects the ladle with the torch. Another object of the invention is to so mount the ladle bowl in its supporting element that it will be rotated automatically about a transverse axis near the upper edge of the bowl as the torch is moved out of a horizontal position to various angular positions. This feature enables the ladle to be used to reach work in corners and other unhandy places where solder or other substance must be applied to the material worked upon. \Vith this construction the upper edge of the ladle bowl automatically remains horizontal and thus keeps the contents of the bowl from spilling. The present invention will be best understood in all its features and advantages upon consideration of the following detailed description taken in connection drawing and the scope of the invention will be particularly pointed out in the appended claims.

At the outset, it may be noted that the present application is a division of my prior application Serial No. 480,017, filed June 24, 1921, Patent No. 1,487 ,359, dated March 18, 1924.

In said drawing, Fig 1 is an elevation of a portion of a torch and of a ladle constructed and arranged according to the present invention to lie in the path of the flame emitted from the torch outlet, and Fig. 2 is a similar view of a modified ladle structure by which out of the way places may b a hed in pra t ce.

Serial No. 480,017. Divided and this application filed February 1924. Serial No. 691,372.

Referring to the drawing in detail, 10 designates the body of the torch, which is bored out sov as to provide a central mixing and combustion chamber 11. The downwardly extending associated tube 14 connect the torch body with its fuel supply tank 15. A pump is employed to force air into the'tank 15Iand thereby place the'fuel, which is ordinarily gasoline, under pressure. age from the opening through shank 13 to the combustion chamber extends through the body of the torch and is controlled by a needle valve 19 secured to the forward end of valve rod 20 which is, in turn, provided at its rear end with an .angularly disposed handle 21. A fuel pan 30 is pro vided for holding a charge of fuel by which the torch is heated at starting, Air is supplied to' combustion chamber 11 through the holes 31. A finger piece 33 enables the torch to be readily handled. The torch construction is more fully illustrated and described in my aforesaid Patent 1,487,359 dated March 18, 1924. i

As clearly shown, the ladles, constructed and arranged in accordance with the present invention, are so positioned that the flame emitted from the torch impinges directly upon the bowl of the ladle. Two ladle constructions are shown. In the first instance the ladle, designated generally 7 5, has a bowl 81 and a connecting pin 41 which is in the nature of a handle. The bowl is secured to the outer end of the pin 41 and lies in a position to have its lower rounded portion engaged by the flame emitted from the end of the torch. In this instance, the bowl has a projection 76 in the form of a boss which is bored out for the reception of the forward end of the pin 41, and a set screw 77 passing through a threaded opening in the projection 76 engages the pin 41 to securely hold the parts together. In this instance, the ladle will be held from rotation and the torch and ladle may be handled as a unit. This arrangement is advantageous where the torch is provided with a light fuel tank 15, and where the tank, torch and all are handled by the user as a single tool. In such case, the solder or other contents of the bowl 81, when heated, may be readily poured out by the user merely picking up the whole tubular shank 13 and an device and zhandl'ing it as a single instrument.

Before passing to the next form of the invention it should be pointed out that the rear end of the pin ll extends into an open ing in a boss 43 formed upon the body of the torch, and a set screw a l serves to securely hold the pinsin place. By the use-of these parts the ladle 75 is firmly attached to the torch l0 and, as noted, both ladle and torch. :may be used as-a single instrument.

In somecases, notably in electric wiring, it may be desirable to employ a ladle which willallow of certain movement of the torch, without changing .the position of the solder or other substance in the-bowl of the ladle. In-such instance, a ladle of the type illustrated in Fig. 2 may be employed. This ladle, designated generally as 78, has bowl 82 pivotally mounted between the ends of a bifurcated arm 79 whiclrextends outwardly as a permanent extension of the pin etl. lVith this construction the bowl 82 is pivotally mounted so as to freely rotate aboutanaxis passing through the pivotal points 80 located nearthe upper edge of the bowl. So long as the torch is moving about this axis, the ladle bowl will remain upright and its contents will not' be spilled. lVith this construction it is possible for an electric wire-man to get into corners and other outof the way plaees-in'order to-dip the twisted ends of awire-joint into the solder 'containedwin the ladle bowl or pot82, and thus make a. soldered joint. Indeed, the arrangement'may be used in any place What I claim as new and desire to secure by a patent of the United States is:

1. The combination with a torch having a combustion chamber provided with an outlet through which the heating flame is adapted to pass, of a ladle having. a bowl provided with an exterior-1y rounded bottom and lower portion, a bifurcated supporting arm pivotal] y securedat its forward bifurcated end to opposite portions of said bowl near its upper edge and connected at its rear end to said orch at a point above said outlet, whereby the bowl will remain upright invarious positions of the, arm and torch and the emitted flame will play constantly in all said positions upon the rounded lower portion of said bowl.

2. In combination with. a blow torch, a solder holding pot, a yoke affixed. to the torch and extending adjacent the path of the flame, and pivotal bearings by which the pot is suspended. from said yoke in said path of the flame.

In testimony whereof, I hereunto subscribe my name this tth day of l ebruar r, A. D. 1924.

JOHN PETERSON.
