Title: Improvements in and relating to return bends for metal pipes
IPC: B21C37/28
Filed: 1929-08-22
Abstract: 333,064. Babcock & Wilcox, Ltd., (Babcock & Wilcox Co.). Aug. 22, 1929. Pipes. - Return bends for pipes are made by forming a longitudinal hole in a solid bar and then bending the ends thereof into the desired positions. A solid bar is first heated at its ends and then upset to form flanges, is then bored or drilled at 4 and is finally bent to form the return bend. The flanges may have bolt holes and counterbores to receive the ends of the connecting tubes. 'The bore may be formed so that there is less metal at the part which is to form the inside of the bend than at the part which is to form the outside of the bend. This may be effected by drilling the hole eccentrically in the bar, by drilling inclined holes from opposite ends, by removing metal at 10 from a concentrically drilled bar, or by bending the middle part or, as shown in Fig. 10, the whole of the bar, prior to drilling.

Title: Improvements in or relating to braking devices for pit tubs, wagons and the like
IPC: B61H7/02
Filed: 1923-10-15
Abstract: 223,730. Allen, B. Oct. 15, 1923. Actuated by relaxation of pull; hand actuation; skid; scotch blocks; locking by positive detents; blocks and shoes.-Longitudinal movement of the draw-bars of a vehicle upon relaxation of the pull thereon effects the positive locking of all the wheels and mav also apply brakes between the wheels and the track. Provision is also made for hand actuation of the locking and braking means, whilst the pressure of a following vehicle on a supplementary buffer-bar may free the locking means and release the brakes. Each of the sliding draw-bars b is slotted at e to receive a guidepin d on the other, and each is further slotted at c to accommodate a transverse shaft a which engages a slot i in each draw-bar by means of pins h on cranks g, whereby the movement of the draw-bars is equalized. Each draw-bar carries a fixed pawl j and a spring-pressed pawl k coacting with ratchet wheels m, n mounted on the wheel axles, and also carries a transverse lever o pivoted at p and adapted for hand actuation at the end more distant from the point p of a locking-lever q being provided at that end to prevent undesired movement of the lever. When the draw-bars are extended, as shown in Fig. 3, the pawls are disengaged from the ratchet wheels, but on relaxation of the pull, the draw-bars move inwardly under the action of their springs, and each pair of pawls engages with its corresponding pair of ratchet wheels to lock the latter against rotation in either direction. Brake shoes r may be provided on vehicles used on steep gradients, which are adapted to be engaged between the wheels and the ground, either by the movement of the levers o or, as shown, by the movement of transverse levers s connected to the draw-bars. As shown in Fig. 5, each brake shoe is pivoted in a slot y in a member t and is normally held clear of the ground by a spring z, and the member t is slidably mounted on a pin w, and is adapted to slide against the resistance of a spring v, in a forked member pivoted at t<3>, so that it may have lateral play. Buffer-plates 2 mounted on stems 3 may be provided, having extensions 6 provided with notches 7, 8 with which a pin 9, carried by a link 10 pivoted by means of a slot 12 on a pin 11, may be caused to engage. With the pin 9 in the notch 7 the buffer is inoperative, but when, as shown, the pin is engaged with the notch 8, the link 10 bears against the lever o and the buffer is held extended, so that if a following vehicle strikes the butter, the consequent movement of the lever o moves out the draw-bars and unlocks the wheel. A forked hand-lever 13 engaging the lever o may be provided, which may be locked by a locking-lever 14, and in passenger vehicles, hand-levers engaging the ends of the. levers o may pass through the vehicle body to permit actuation of the locking-means by the passengers.
