Granted: 1903-06-18
Abstract: 14,143. Marsh, C. W. E., and Price, B. June 21. Rolling. - Relates to improvements in the machinery for making pipes and tubes from hollow blooms, described in Specifications No. 6283, A.D. 1894, No. 9917, A.D. 1897, and No. 13,985, A.D. 1900, in which the rolls are traversed, and reduce the bloom by a step-bystep action. The mandrel on which the tube is rolled is secured to the feed-screw 7 by cottars 11, 44. The screw is rotated and fed forwards, through the nut 29<a> , at intervals, by means of the half-clutch 33, which has a feather, sliding in a groove 7<a>. The half-clutch 33 is pressed by a spring into contact with a half-clutch 34, formed in one with a bevel-wheel 18, which is continuously rotated by the main spindle 24 through the gearing shown. When the rolls grip the tube, the screw is held from rotating by the mandrel, and the clutch is automatically disengaged. The tube abuts on a sleeve 6, which is held in the position shown in Fig. 1 by the cottar 44. When the end of the sleeve comes in contact with the ring 4, the sleeve is rotated slightly to bring the cottar in line with the slot 37<a>, so that the sleeve can be pushed along the screw to allow the whole of the bloom to be rolled out. After the rolling operation has been completed, the cottar 11 is removed, and the mandrel is pushed towards the left in Fig. 1, to bring the end of the tube outside the bracket 2. A forked lever 3 is then brought down over the mandrel, and the carriage 8 is moved to the right, to draw the mandrel from the tube. This movement of the carriage 8 may be effected by steam, air, or hydraulic power, acting on the rod 14. When steam or air is used, a liquid cataract-cylinder controls the movement. The screw is withdrawn by throwing the half-clutch 33 into contact with a half-clutch formed in one with the bevel-wheel 9, driven in the manner shown.

Abstract: 11,740. Manke, A., Weidigt, B., and Schoppe, F. May 21. Fastenings for doors etc.; " caretakers " for property &c.-Relates to a wararobe for theatres &c., with which is combined a hook for overcoats and the like, both the hook and wardrobe being opened by the insertion of a check, which is returned when the proper coin is inserted. The hook 1 is pivoted in a bracket 4 fixed to a wall board 3, and is locked, together with the door 42 of the wardrobe, by pushing back the head of the hook against the board 3. The locking is effected by a pivoted lever 7 ending in a hook which assisted by a spring 29 engages a projection 10 on a rod 11 connected with the hook. The lever 7 is caused to engage the projection 10 by a spring 16, and is moved out of engagement by a pivoted lever 14, which is provided with a handle and the lower end of which engages a pin 15 on the lever 7. The lever 7 is locked, until the check is introduced, by a pivoted lever 19 which is connected by a flexible rod 22 with a balanced lever 21 carrying an adjustable weight 24. To prevent the immediate return of the lever 19, the weighted lever 21 is so constructed that the part connected with the lever 19 has an overweight. The lever 19 is returned to the horizontal, after the hook and door have been opened, by a projection on the rod 11 which, as the latter rises, lifts one end of a pivoted lever 27 so that the other end presses down a bolt 20 on the lever 19. The door 42 of the cupboard is locked by a pivoted lever 43, attached at one end to the rod 11 and carrying at the other a spring having a projection which enters an eye on the door. Coin action.-When a check is dropped through the shoot 25, it falls on to the lever 21, which is thereby depressed and pulls down the outer end of the lever 19, thus freeing the lever 7. The coin is inserted in a slot 37 and is guided by a frame 33 into a slot in the end of a weighted lever 36, which is thereby depressed. The other end of the lever rises and lifts a lid 30, allowing the check to slide out. Fraud, preventing.-To prevent the lever 21 from being depressed by a wire inserted in the slot, the shoot 25 is curved and is entirely closed except for an opening in the bottom. Openings are provided through which smaller, bigger, or heavier objects than the check fall without touching the lever. A cap 41 prevents the lid from being lifted by hand. The frame 33 has lateral openings through which smaller coins drop into a receptacle 52.

Granted: 1905-12-21
Abstract: 28,522. Mackenzie, W. J. Dec. 28. Track apparatus for interaction with moving trains ; signalling to cabins and stations ; crossing-gate signals; signalling approach of trains; handlevers and hand-gearing ; accidents, signalling in case of.-Relates to systems of electric signalling on railways, in which, when a train arrives in the signalling area, a signal is in any case received, the nature of the signal being controlled from the signal box. Two insulated rails or wires a, c are supported between the track rails in the signalling-area. The rail a receives current by means of a trolley wheel q from a dynamo o, Fig. 4, carried by the engine. A second trolley wheel s running on the rail a is connected by a wire s<2> to a green signal lamp s<1>, bell s<3>, semaphore a<4>, and whistle, and thence to the engine frame. A trolley wheel t running on the rail c is connected by a wire t' with a red signal lamp t<3>, bell t<3>, semaphore t<4>, and whistle. Wires e, h, Fig. 1, pass from the rails a, c to the signal cabin f, where they connect respectively with the green lamp, bell, and semaphore j, j<1>, j<2>, and the red lamp, bell, and semaphore l, l<1>, l<2>. By means of a switch g, the signalman can connect the wires h, e. When the train reaches the signal area, the dynamo supplies current from the rail a to the green lamp &c. s<1>, s<3>, s' on the engine, and also to the green lamp &c. j, p, j<2>. If the signalman has closed the switch g to give a danger signal, the dynamo will also supply current to the rail c and consequently to the red lamp &c. t<2>, t<3>, t' on the engine, and to the red lamp &c. l, l<1>, l<2> in the signal box. By means of a switch u, the driver can connect the dynamo with the rail c for the purpose of communicating with the signalman by means of flash signals on the lamp l<2>, and the signalman can use the switch g similarly for giving flashes on the lamp t'. Fig. 7 shows the method of supporting the trolley wheels q, s, t. The springs z<6> allow of lateral movement, and the plunger z<2> and spring z<1> allow of vertical play. A station platform can be lighted up as the train approaches, the lamps N, Fig. 1, being supplied with current from the dynamo through the rail a, wire v, switch v<1>, wire v<2>, and track rail b. Level crossings are protected by means of insulated rails connected with lamp, bell, and semaphore signals at the crossing. The switch g in the signal cabin may be replaced by contact-pieces adapted to engage with the signal lever while the signal is at 'danger.' Fig. 10 shows apparatus so constructed that, if the signal wire a<7> breaks, the balance lever a<6> lifts the rod a', which is pivoted at a<2> into engagement with both rails a, c, thus giving a danger signal on the box and on the engine when the train reaches the signalling area. Instead of supplying the current from a dynamo on the train itself, it may be supplied from some other source.
