Title: Improvements in or relating to machines for bending pipes,rods and bars
IPC: B21D7/024
Filed: 1963-12-20
Abstract: 1,065,890. Angular bending. BACKER ELEKTRO-VAERME A.B. Dec. 20, 1963 [Jan. 18, 1963], No. 50550/63. Heading B3E. A machine for bending pipes, rods and bars comprises a rotatably mounted, preferably motor driven, bending head which on its upper surface carries a coaxial mandrel and a dog laterally offset relative thereto which serves to bend the pipe about the mandrel, a sectorshaped arm, for the pipe length, pivotally mounted on a shaft parallel to the head axis and fixedly located a radial distance from the head axis greater than that of the dog therefrom so that the arcuate surface of the arm forms an extension of the engaging surface of the dog at the start of a bending operation and is carried along with the pipe during the bending operation. The machine comprises a plate 4 beneath which is rotatably mounted a clutch head (5), Fig. 1 (not shown), carrying a bending head 7. Secured to an axial shaft is a gear 14 driven by a gear train and electric motor means (not shown) to which is secured a clutch cone 17 co-operating with the head 5. The clutch is pneumatically operated and controlled by an electromagnetic circuit which is closed manually and opened automatically. An exchangeable bending mandrel 18 is screwed into the centre of the bending head 7 and a dog 20 having a pipe locating shoulder 22 is adjustably mounted in an offset slot 19 in the bending head so that the distance between the mandrel and shoulder is equal to the pipe diameter. A stop means 25 adjustably mounted on the periphery of the head 7 co-operates with a switch means to open the circuit and stop the bending head. A sector-shaped arm 26 is mounted on a pivot adjustable along a slot 29 in a lateral extension 28 of the plate 4. In the starting position the head 7 is positioned so that the slot 19 is parallel to but offset from the slot 29 and the pivot positioned so that the curved periphery and stepped portion 32 of the arm forms a continuation of the stepped portion of the dog 20. To bend a pipe freely located between the mandrel and dog, one end of which is set against a stop, the machine is started to form the bend about the mandrel and at the same time the pipe draws the arm in a clockwise direction thereby lifting a weight attached thereto. When the head rotation is halted the arm is retracted by the weight and the bent pipe manually removed. The machine may be used for bending electric tubular heating elements having one or more resistance wires embedded in a pulverized insulating material.

Title: Timer accessory track unit
IPC: G04F7/10
Filed: 1967-11-20
Abstract: 1,154,510. Slot-racer timing device. IDEAL TOY CORP. 20 Nov., 1967 [3 Oct., 1967], No. 52637/67. Heading A6S. An accessory slotted track unit has an integrated clock mechanism for timing vehicle movement around a ,track. An actuating member connects with the clock mechanism and the battery operated vehicle's guide means whereby several traverses or a portion of a traverse round the track may be timed by manual operation of the actuating member, and one complete traverse of the vehicle round the track may be timed by manual operation of the actuating member to release a vehicle and to initiate the timing mechanism, the latter being terminated by contact of the actuating member by the vehicle guide means on its return to the starting position. In the embodiment illustrated (of Figs. 2 and 5 which illustrate a bottom plan view of the accessory track unit) the clock mechanism 32 includes an oscillating pendulum 34 the movement of which is prevented by actuating member 38 in the position illustrated in Fig. 2; movement of member 38 into slot 34a in pendulum 34 releasing the latter for oscillating motion. To time one complete traverse of a vehicle around the track the handle portion 38d of member 38 is manually moved in the direction "A" (Fig. 2) (with the inclined cam surface 38c connecting wall 10b of the track unit) to release the depending guide 22 of the vehicle (initially held by member 42 on member 38) and to simultaneously release member 34 for oscillation. This movement of member 38 is a pivotal one about pivot 40, which is connected to member 38 by the resilient arm 38a, and a further pivotal movement, about the juncture 40a of the integral arm and member 38, the resilience of the arm 38a biasing member 38 to return through the latter pivotal movement on release of handle 38d. Thus member 42 partially protrudes into guide groove 16a and on the return of the vehicle, guide memher 22 contacts member 42 to cause member 38 to move into its original position thus terminating, the oscillatory movement of pendulum 34. To time several traverses, or a partial traverse, of the vehicle around the track handle portion 38d of member 38 is pushed in direction "C" (of Fig. 5) whereby member 42 is completely removed from within the groove 16a until handle portion 38d is pulled in the opposite direction to terminate the operation of the timing mechanism. The clock finger 28 is connected via shaft 30 to the clock mechanism and finger 26 may be moved manually to indicate the number of traverses of the vehicle around the track.
