Title: Improvements in or relating to methods of forming circular bodies or conical discs suitable for use in the construction of vehicle wheels or the like
IPC: B21H1/00
Filed: 1942-11-02
Abstract: 563,859. Making conical discs for vehicle wheels &c. BORG-WARNER CORPORATION. Nov. 2, 1942, No. 15400. Convention date, Nov. 3, 1941. [Classes 83 (ii) and 83 (iv)] Conical discs for the construction of vehicle wheels are made from flat stock by bending and welding into tubular form and rolling the strip to a taper either before or after welding to produce the conical shape. Tapering after welding may be effected between a conical roll 27 and a cylindrical roll 26 having a flange 29 to prevent the work from leaving the pass at its wider end. In a modification, oppositely arranged conical rolls 30, 31, Fig. 3, are employed. The coning of the part is limited by contact of the flange 29 with the surface 70. The work engages the flange 29 by one edge only until the coning is complete. In further forms, sets of conical rolls similarly arranged are employed, the pass converging towards the larger ends of the rolls. The tube may be rolled on a cylindrical roll 36, Fig. 9, by a traversed roll 37 that gradually approaches the roll 36. The tube may be forced over a flaring mandrel 40 by a pusher 39, a roll 37 assisting flow. In a further form, the tube is forced over a conical mandrel surrounded by conical rolls. The thick centre of the conical discs may be flanged over, for hub connection, whilst supported on a conical mandrel, either by a traversed roll or by a die 48, Fig. 13. In another method reversely arranged, double blanks 51, 52, Fig. 14, are cut without waste from a strip, the blank 51 is thinned at the edges by rolling, is cut along the centre line trimmed if desired, and bent up to conical form and welded. The blank 52 is similarly treated but is thinned at the centre.

Title: Bench type honing machine
IPC: B24B33/02
Filed: 1946-05-21
Abstract: 631,455. Honing-machines. DEHN, S. G. (Automotive Maintenance Machinery Co.). May 21, 1946, No. 15404. [Class 60] In a bench-type honing machine having an adjustable feed rod for expanding the hone pieces and a driving member coupled through a clutch to a drive spindle, the feed rod and drive spindle are operated by a manual control which when in an inoperative position holds the clutch disengaged. A feed rod 28, Fig. 3, is freely mounted in a hollow drive spindle 27 which is journalled in a supporting housing 34. A drive pulley 37 is mounted on the spindle so that the centre portion of the pulley, together with a member 50 keyed slidably on the spindle and a collar 49 fixed on the spindle, forms a friction clutch having a lining 48 of leather or other suitable material. A spring 29 tends to retract the feed rod 28 and a spring 52 tends to hold the clutch engaged. The housing 34 has arms 56, Fig. 5, on which pivots a head member 58 secured to a lever 53. The lower part of the head member acts upon the clutch member 50, Fig. 3, whilst to the upper part is pivoted a T-shaped member 65 to which a shaft 67 is secured by means of collars 68. The shaft 67 is adjustably mounted in an overarm member 69 having an arm 70 with a bearing 32 for the end of the feed rod 28. Movement of the lever 53 in a downward direction causes the head member 58 to pivot on the arms 56 ; the lower portion of the head member engages the clutch and the upper portion imparts a forward movement to the overarm 69 which transmits this movement to the rod 28 and expands the hones. Upon release of the lever 53 the spring 55 disengages the clutch against the pressure of the clutch spring 52 and withdraws rod 28 allowing the hone to contract. Adjustment of the relative positions of the member 65 and overarm 69 and hence of the movement of the rod 28 is effected by knob 83 acting through a coupling pin on the shaft 67. The lever 53 passes through a slot in the front plate of the machine, downward movement of the lever being limited by the lower edge of the slot.
