Abstract: 7454. Stewart, W. J. May 28, 1908. Piles ; p i l e s, driving. - Relates to the method of driving hollow reinforced concrete piles by means of a driver acting within the pile, and formed with projections engaging with projections on the interior surfaces of the pile. The improvements comprise the use of segmental projections 11, Fig. 1, on the driver, and corresponding segmental projections 10 on the pile, or, as an alternative, pivoted levers 13, Fig. 4, which are separated by means of disks 15 on a rod 16, may be caused to engage with shoulders 12, on which are placed cushions 6. A collapsible shoe, Fig. 7, may be employed in combination with these drivers. This comprises arms 19, to which a light mantle 22 is temporarily secured, and movably pivoted to the driver by means of pivots 21 running in slots 20. When the driver is withdrawn, the mantle 22 is left in the ground, the disk 23 rises into a cavity, and the arms 19 collapse. The driver may be constructed of T-irons, Fig. 6, bolted or riveted together and carrying collars or projections, not shown. Specification 28,269/07 is referred to.

Abstract: 10,809. Stewart, W. C. May 10, 1906, [date applied for under Patents Act, 1901]. Insoles. - Relates to a machine for slashing insoles to render them more flexible, and particularly adapted for welt insoles, in which the slashes must not extend to the usual channel. The machine is adjustable for any insoles, irrespective of their size or width, and whether they be rights or lefts. To enable the length of the slashes to be varied according to the variation in the width of the insole, or in the distance between the channel lips of a welt insole, at different parts, the slashing-knife is given two operative movements for each feed movement, and, by an automatic transverse movement of the knife, the overlapping of the two slashes is varied as required. Fig. 10 shows diagrammatically a slashed insole, in which one cut of each pair is represented by double lines a, and the second cut by a single line b, the amount of overlap varying according to the contour &c. of the insole. The knife 18, Figs. 3 and 4, is adjustably mounted between clamping-jaws in the holder 17, which is capable of transverse movement in the guide-plates 16 fixed to the slide 14. This slide is reciprocated, to operate the knife, by an eccentric on the driving - shaft 2, the eccentric-rod being connected to the slide by a ball- and - socket joint, and screwing into the eccentric strap, to permit of its adjustment. To effect the transverse movement of the knife, the holder 17 is connected by a link 21, Fig. 7, to the arm 22 of the three-armed bell-crank 22, 25, 26, the arm 26 being connected under the control of springs 30 to the sliding rod 28, which is reciprocated by the crank 31. The operative movement of the link 21 is restricted by the arm 25, through the mechanism shown in Fig. 5, so that the transverse movement of the knife is automatically adapted to the requirements of the work. The arm 25 is connected under the control of springs 75 to the sliding rod 71, which has a bent end engaging between the wedge-shaped blocks 68, 69, Figs. 5 and 7. These blocks are connected by links 67 to the pivoted spring-connected arms 64, which are provided with feelers 65 adapted to engage the margin of the insole, as shown, or the channel lip. As the insole passes between the feelers, the blocks 68, 69 are moved apart or towards each other according to the variations in the contour, and thus determine the movement of the rod 71 and, consequently, of the knife, the surplus movement of the rod 28 being taken up by the springs 30. The insole is inserted between the feed-roller 37 and the pressure roller 38, Fig. 4, up to the stop 57 on the pivoted arm 58. A treadle is then depressed, which, through the rod 56 and lever 55, lowers the flexing-roller 54 to bend the insole over the curved anvil 36, so that the knife acts on the convexed upper surface of the work. The Iressure roller 38 is normally held up by the pin 52 on the arm 53 of the flexing-roller, until the latter is depressed by the treadle against the action of the spring 57, on which the roller 38 is forced into engagement with the work by the springs 51. On the downward movement of the flexing-roller also, the ear 62 engages the arm 61 of the stop 57x, and raises the stop clear of the work. The feed-roller is driven intermittently through a, preferably, roller clutch, which is actuated by a block on the rod 43, Fig. 7, coupled to the rod 28. The return movement of the clutch actuator is limited by a stop, which can be adjusted to limit the stroke and, consequently, the amount of the feed movement. A similar clutch 46, Fig. 3, is provided at the other end of the roller to prevent any return movement. Means are provided for automatically stopping the machine after a given number of effective movements. The driving - pulley 3 is coupled to the shaft 2 by a suitable clutch, that shown in Fig. 3 being a roller clutch in which the roller cage 7 has a projecting lug 10 adapted to be engaged by the spring-controlled stop-hook 78. This hook is mounted on a pivoted arm 80 engaged by the forked end 87 of the lever 86x, which is connected by the toggle-links 90 to the arm 91 x of the flexing-roller. The toggle-joint is normally supported by the block 93, and, when the tread!e is depressed to start the machine, the pin 91 at the joint is raised into the seat 94. On the frame is mounted a rack-bar 95, which is raised step-by-step by the crank-pin &c. 100 engaging the teeth 99, the ratchet-teeth 101 at the lower end of the bar being engaged by the pawl 103, to prevent return movement. The bar 95 has at its lower end an adjustable block 102, which, on the upward movement of the bar, ultimately displaces the pin 91 from its seat, so breaking the toggle-joint, and causing the stop-hook 78 to come into action, even if the treadle be held depressed. The transverse reciprocation may be imparted to the work instead of to the knife.

Abstract: 19,657. Stewart, W. J. Sept. 12. Electric railways and tramways; rope railways and tramways; points and switches. - Relates to the simultaneous working of points and plough guides on electric and cable tramways or railways, and consists partly of improvements on the means described in Specifications No. 16,667, A.D. 1900, and No. 23,485, A.D. 1901. Fig. 1 shows a plan, and Fig. 2 a transverse section of the points. The pivoted curved lever A, by means of the antifriction rollers D working in the connecting-rods F, transmits movement from the point tongues 4 to the plough guides E. The point tongues 4 are provided with projections 5, which are acted on by plungers on the car. In one modified arrangement, the ends of the lever A work within sleeves which rock in the eyes of the connecting-rods F, and chains over pulleys facilitate the tilting movement of the lever A. In another arrangement, the point tongues are shifted by a pivoted curved lever as before, and they are connected to the plough guides by means of levers and connecting-rods. A rectangular frame reciprocating on supporting-rollers may be used instead of the pivoted curved lever. Fig. 8 shows an elevation of the plungers on the car, and illustrates how each is operated by a bolt J worked by a weighted lever I, each bolt being so long that, when withdrawn from the plunger B on one side, it will enter a notch in the plunger on the other side, thus preventing the fall of the plungers simultaneously. In order that the plungers may easily pass round corners, they are made to slide in grooves, as shown in Fig. 10, so as to be capable of lateral as well as vertical motion.

Abstract: 1299. Stewart, W. H. Jan. 19. Conductors.-Relates to a method of supporting overhead conductors so that in case the conductor breaks the broken wires becomes dead. The Figure is a sectional view of the supporting-device. When the conductor D breaks, the part A which is soldered to it slips out of the bevelled-shaped case B and becomes suspended and insulated by the cord C. As the part A slips out, the projection I knocks the rotatable piece G, thus pressing it against the projection E and preventing the other piece from being liberated. It is stated that the piece G may be held, after being moved to one side, by means of a'suitably-placed spring.

Abstract: 16,667. Stewart, W. J. Sept. 19. Points and switches for electric and other railways or tramways worked from the vehicle. The tongue b is pivoted to a lever e, which works in a deepened part of the rail groove c, and is knocked over by a plough carried by the vehicle. Both tongues may be similarly provided, and may be connected by the rod g. The lever is covered by hinged or other covers h, i, which are shown opened. Beyond the point, the groove is made shallower so as to lift the operating-appliance on the car. The tongues and the rail grooves may be provided with openings to pass or expel dirt &c. On the vehicle, the rod o carrying the plough v for operating the points is lowered by the lever k and a treadle or otherwise, and it can be held raised by a ratchet &c. u. Wings w on either side of the plough deflect the dirt sideways, and a roller q runs in the rail groove to lift the device when it meets the shallower portion. This appliance may be fitted on both sides and both ends of the car.
