JAMES L. ANDERSON, or BAYONNE, NEw JERSEY, ASSIGNOR, BY MESNE ASSIGN- mEN'rs, TO AIR REDUCTION COMPANY, INCORPORATED, or NEW YORK, N. '51., A

CORPORATION OF NEW YORK.

WIRE-FEEDING DEVICE.

Application filed February 17, 1920, Serial No. 859,463. Renewed March '13, 1922. Serial No. 548,459.

To all whom it may concern: Be it known that I, J AMES L. ANDERSON,

a citizen of the United States, and resident;

of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and useful Wire-Feeding Device, of which the following is a specification.

The object is to provide a simple, compact and effective wire-feeding means for welding torches. To this end the invention comprises the unitary supporting and feeding device, hereinafter described in its preferred embodiment and more particularly pointed out' in the appended claims.

In the accompanying drawings, forming a part hereof:

Fig. 1 is a side elevation of the invention an adjusting bracket;

Fig. 2 is an enlarged plan view of the d e; vice, omitting the motor; Fig. 3 is a front view of the device;-and

Fig. 4 is a detail perspective view of a part on a still larger scale.

The drawing represents an oxyacetylene or like welding torch 1, which is mounted upon an adjusting bracket 2, forming the subject-matter of a separateflapplication. The torch has a cylindrical stock 3 and a tip 4 containing passages 4* from the flame jets are delivered. A

On the upper part of the torch stock, above the bracket, is a c1amp-5 for supporting the wire-feeding means. The clamp comprises two parts, each comprising a portion of two laterally

united collars

6, 7 and a connecting web 8. The collar 6 is relatively small, to embrace the torch stock, and the collar 7, relatively large to receive a cylindrical electric motor 9. The two pieces of the clamp are united by screws 10 passing through the webs 8, the relations being such that when the collars are thus assembled their ends 11 are separated, so that they may be drawn together resiliently by screws 12 upon the stock and motor.

The motor may thus be supported at the front and somewhat to one side of the stock of the torch, with its armature shaft 14 projecting downwardly. The motor is pro-' which the motor-clamping portion of the other half. A- supplementary bracket piece 18 is applied to the inner face of a hub 19 on the lower end of the bracket 16, said piece having a transverse opening and a projecting bushing 20, which latter passes through the ,hub and is engaged at the outer side there- The bracket piece 18 also has another transverse opening 2O in. which, by nut- 27, 'fissecured the stub journal of a grooved applied to a torch, which is mounted upon guide roller 28', peripherally opposite the feed roller 23.

Lugs

29, 30 .projectin'g inwith the interval between the rollers. Sec

section extending downward to the torch tip 4,'where its lower end is secured at the entrance of a wire duct 33 passing through the tip. .The wire a from a suitable supply, notv shown; passes through the guide tube and between the rollers, downward to and through the torch tip, where its extremity is continually melted off by the heat of the jets to add itself to the metal of the weld. The construction of the tip with its passages for jets and for the'wire, and the combination of the same with means, generally, for

'feedin wire through the wire passage, form the su ject for a separate application.

What I claim as new is: 1. A wire-feed for welding torches comprising a clamp including a torch-embracing portion, shaft bearings and a motor-carrying portion, a transverse shaft in said bearings, a wire-feed roller and a gear-wheel on said shaft, and a motor supported by the motor-carryin portion of the clamp, geared to said gearheel.

2. A wire-feed for welding torches, in cluding a clamp comprising torch-clamping and motor-clamping collar portions laterally united with each other, a motor in the motor-clamping portion,and a transverse shaft in the support geared to the motor shaft and bearing a wire-feed roller.

,tions of a guide tube -32"are secured at their adjacent ends in these openings, the lower 3. A wire-feed for welding torches, in-

cluding a clamp comprising torch-clamping and motor-elamping collar portions laterally united with each other, a motor in the motor-clamping portion having its shaft projecting downwardly, brackets extending downward from the clamp, and a transverse shaft journaled in said brackets bearing a feed roller and geared to the shaft of the motor.

4. A Wire-feed for Welding torches, comprising a clamp having a torchembracing, portion and a motor-carrying portion. a motor supported by said motor-carrying portion of the clamp, a bracket on the clamp bearing a guide-roller. a shaft journaled in the bracket bearing a feed-roller opposite the guide-roller, and gearing between said shaft and the motor.

5. In a wire-feed for welding torches, the

combination of a torch clamp, a wire-feed roller carried by the clamp, a motor on the clamp geared to said feed-roller, a bracket piece held fast to the clamp on a pivot per- Initting its angular adjustment about the axis of the feed roller, and a guide roller carried by said bracket piece peripherally opposite the feed roller.

6. In a Wire-feed for Welding torches, the combination of a torch clamp, a Wire-feed roller carried by the clamp, a motor on the clamp geared to the feed roller, and a bracket piece held fast to the clamp on a pivot permitting its angular adjustment about the axis of the feed roller and carrying a guide roller opposite the feed roller and means for guiding the Wire in alinement with the interval between the rollers.
