Granted: 1903-06-11
Abstract: 14,057. Johnson, J. Y., [Compagnie Fran- þaise de l' AcÚtylÞne dissous]. June 20. Oxy-acetylene and like burners.-The danger of explosion in the pipes and conduits consequent on " lighting-back " in the burner is obviated by arranging the tube D conveying the acetylene or other explosive gas within the oxygen-supply tube A, by forming the tube D with a series of openings a<1>, a<2>, a<3>, a<4> or with a thin longitudinal slit, and by interposing between the tube D and the inlet passage G a chamber F, containing brick or porous ceramic material, of which the pores are very small, but cccupy a considerable total space in proportion to that occupied by the substance of the brick or ceramic material. By this construction, the mixture of the gases is progressively effected along the nozzle-piece, so that the mixture is only completed near the outlet B and is less and less explosible towards the other end, and the extension of any explosion to the passage G is prevented by the porous material in the chamber F. The invention can be applied to the mixture of any number of combustible gases, care being taken to place a chamber containing porous material at the entrance of each tube supplying a gas or a gaseous mixture which is explosible in itself.

Title: Improvements in Electric Coil-forming Apparatus.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-03-20
Granted: 1904-03-19
Abstract: 6502. Carolan, E. A., [General Electric Co.]. March 20. Bending. - Consists of apparatus for winding thin strips of metal on edge into coils. The strip from a reel C, Fig. 2, is led through a slot 12 in an arm 11, which lies inside a tangent to the outer edge of a guide-plate 10 and prevents its rotation by contacting with the toolcarriage or other stationary part of the lathe. An adjustable ring 15, to which a split friction ring 18 is attached, is moved by means of spanner holes 16 until the left-hand end of a diagonal slot in the ring 18 receives the strip, which is pushed through and fastened to a shouldered collar 4. The ring 15 is then turned forwards and held by friction or by clamps. The mandrels 1, 2, and a sleeve 5, into which the mandrel 2 telescopes, are rotated in unison, while the guide-plate 10 and its associated parts, a recessed ring 8, an adjustable ring 15, and a friction ring 17, are held motionless by the arm 11. A hardened steel friction shoulder 7 and the periphery of the sleeved mandrel 2 carry the strip along by friction against the friction of the surfaces of the guide-plate 10 and the ring 17, and prevent the usual distortion of its rectangular cross-section during coiling. A modification is described, in which the mandrels 1, 2 are made integral, and the end of the strip is fastened to the collar 4 by means of a pivoted lever, which is tightened against a shoulder on the collar 4 by means of a screw, a spring, normally, keeping the lever end away from the shoulder. In another modification, Fig. 6, the collar 4 is mounted directly on the mandrel 1, and the winding-head 25 consists of a split ring, which is clamped on the mandrel by the bolt 32, a spring being inserted between the flange 33 and clamping-nut 34. The strip passes through a slot 30 between two arms on the head 25 and friction-wheel 27, these arms preventing their rotation as before. The strip is carried beyond the head, bent up, carried through a slot 28 in the friction ring and attached to the collar 4 as usual, the strip being reduced in width at its end for this purpose, if necessary. A head, similar to this one but for winding two strips simultaneously is also described ; it has two grooves 30 and rings 27 with corresponding intervening spaces. Coils of irregular section may also be made. For rectangular coils, two prismatic blocks 36, 37, Fig. 9, are mounted on the mandrel with a friction plate between them, the strip passing through a rabbet 38 in the block 36, and through a substantially-radial slot in the friction plate to the block 37. A reciprocating guide 43, pressed normally upwards by springs 44, and sliding in a dovetail in a frame 41, which engages the latheways by means of guides 42, causes the rabbeted block 38 to travel when coiling thick slips, an adjustable tension-device is used, which is described as consisting of a guide-box with an adjustable slide, adapted to be moved and adjusted by means of screws.
