摘要： 120,013. Mein, T. O., and Cook., W. J. July 2, 1918. Screwing-dies, after being threaded, have the clearance holes drilled on a jig with a stem 5, preferably screwed to enter the screwed hole of the die, and guide holes 3 , preferably placed as in Fig. 2, so that the clearance holes in the die will run into the tapped hole, leaving little or no metal to be removed by filing. In the latter case, grooves 6 are formed in the stem of the jig.

摘要： 22,721. Mein, T. O. Oct. 4 Doors, wagon.-Relates to means for supporting flap doors while opening and closing them. A lever H is pivoted at M to the bracket K, and is connected by a rod I to the door B at a point above the hinge. The lever H is also connected at H to a rod L, which is drawn inwards by the spring G. The opening of the door puts the spring in compression, and stores up power for assisting the closing of the door. Various methods of applying the spring to the lever H are described.

摘要： 18,130. Hill, A. J., and Mein, T. O. Aug. 10. Brakes.-In railway-wagon and like vehicle brakes operated by a lever on one side of the vehicle, means which are unaffected by wear of the brake parts are provided for indicating at the other side whether the brakes are off or on. A transverse rod a, sliding in a guide b, has one end bent to form a bridle f, which fits over the hand - lever d, so that as the lever is moved from its rest when the brake is applied the rod a is moved horizontally. The other end of the rod may itself form an indicator or it may be connected by a bell-crank lever to a longitudinal rod which operates a rocking shaft k provided with a pointer n adapted to move over marks on the side frame or on a separate plate. In a modification, the bridle f is pivoted to a bracket on the side frame and the rod a connected to its lower end, the bell-crank being reversed. A spring or weight may be used to retain the bridle f in its outer position when the brake is on. Fig. 7 shows a modification in which the rod a is connected by a bell-crank p to a vertically.moving rod q, the indicator being normally retained in the ' off' position by the weight of the lever d on the rod q, and moved to the ' on' position when the brakes are applied by a tension spring r. Fig. 9 shows another form, in which the rod a is free to turn and operate the pointer n directly, the pointer being moved into the on' and ' off' positions respectively by a counterweight s, and by the lever d acting on a crank a on the rod. In the arrangement shown in Fig. 10, the pointer is mounted on a rocking shaft x moved by a longitudinal rod a, placed above or below the brake shaft t, to which it is connected by an arm w engaging a fork or a pair of projections u on the rod. Should the arm w move farther than is necessary owing to wear of the brake blocks, it becomes disengaged from the projections u. Fig. 12 shows a modification in which the shaft x is connected by a link x to a rod a connected by a similar link y to a locking shaft y' having a crank y at its end. The crank y is kept raised by the lever d when in the 'off' position, but when the brakes are applied, the weight of the rod a brings the links x, y into a vertical position, thus moving the pointer. Flexible wires may be used for elements in tension or for those which may be replaced by tension members with slight modifications,

摘要： 11,508. Mein, T. O. May 16. Door-closing apparatus; door stops. -Relates to springs arranged to control the lowering and lifting of railway wagon and other fall - down flaps. The door a, Fig. 1, hinged at b to the wagon frame, is connected with the spring h through a link c and lever e. The lever e is pivoted at f and connected with the rod i by a pin k, which is adapted to move in a guide or guides m in fixed to the underframe g. When the door falls, the spring h is compressed between the washers j, j , the rod i being constrained to move in an axial line. A block n, secured to the bracket d' or to the door a, is adapted to contact with a link c when the door is opened. In a modification, the lever e is pivoted so that the rod i is thrust outwardly, the outer washer being held stationary. As shown in Fig. 2, the spring h is arranged vertically, pins p on the upper washer being adapted to move in slots m of guide-plates m. In a further modification, the lever e is arranged above the spring h.
