Title: Improvements in Electric Arc Lamps.
Filed: 1902-08-12
Granted: 1903-08-12
Abstract: 17,690. Lake, H. H., [General Electric Co.]. Aug. 12. Arc lamps.-The arc is surrounded by a small transparent tube or case of highly-refractory material. The invention is described as applied to two types of lamp, in one of which the upper carbon is fed downwards by its own weight, and is drawn up by a series solenoid operating a clutch. Fig. 2 shows carbons maintained at a fixed distance apart by the tube or small globe 11, of quartz or silica which has been fused. This is clamped by a nut to the upper carbon-holder, and rests upon the lower carbon 10. A spiral spring feeds the lower carbon upwards. The arc is struck by means of the bridging- carbon 12<1>, passing through a central hole in the lower carbon. When the series coil 14 is energized, it attracts an armature 16, and lowers the bridging carbon 12<1> by the linkwork shown. The lower carbon may be fluted. Apertures allow air to pass in between the tube and the arc and upper carbon, the arc being thus induced to keep to the centre or hottest portion of the region. The tube may have a triangular crosssection, Figs. 3 and 4.

Inventor: WARNER ARTHUR WELLESLEY
Filed: 1902-11-01
Granted: 1903-10-31
Abstract: 23,862. Warner, A. W. Nov. 1. Artificial bait.-Relates to an artificial fish made of rubber, silk, or other flexible material, for use as a bait. Figs. 1 and 2 show views of the bait fitted with hooks. The rubber or silk body a is made hollow, with a slit in the tail-piece so that the hook g can pass therein and be partially hid. The head c and fins d are preferably made of sheet brass and attached to the metal tubing b. The Provisional Specification states that the fins d are bent in opposite directions so as to set up spinning when drawn through the water. The fish line f passes freely through the tube b and body a, and is attached to the hooks g, h. The elastic band i, shown in Fig. 2, keeps the tail-pieces e together. When a fish is hooked, this arrangement of line and bait allows the bait to pass up the line, as shown in Fig. 3, thus assisting disgorging and preventing injury to the bait. A modification is shown for small baits in which the metal head is dispensed with, the india-rubber body a being simply drawn over the tube b.

Title: Improvements in the Mounting of Railway and Tramway Rolling Stock.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1903-03-23
Granted: 1904-02-11
Abstract: 6715. Thompson, W. P., [Bange, C. T. M. V. de]. March 23. Axle - trucks or undercarriages; axles; wheels.-Relates to arrangements of the wheels and axles of rolling stock for electric or other railways and tramways for facilitating passage round curves. The body a, Fig. 2, of a vehicle is suspended on a pair of two or four wheeled trucks placed beyond its extremities. The body is supported on the truck by ball joints g and brackets i, the axis of turning of which is above the centre of gravity of the body. The ball joint g is formed at the top of a frame/, which rests on springs e oa outside axle-boxes. A central post h on the frame f passes through a transverse slot in the end of a bracket k on the body, and keeps the frame f in a vertical position. The flanges of the wheels are external to the rails, and the wheels are mounted loosely on the axles by means of long hubs, which are not lubricated. If a four-wheeled truck is used, each axle s, Fig. 5, is mounted in a frame t, and the two frames t are connected to an intermediate frame p by ball joints q and posts u. The body is suspended by a framing l connected to the ends of a long transverse spring m resting on a block n, which is guided vertically in the framing l and rests on a ball o on the frame p. In another arrangement, for a two-wheeled truck with externally-flanged wheels, each wheel 11, Fig. 8<a>, is fixed to or formed in one with a half-axle 5, on which a cross-beam 6 is supported by bearings 8, 9. The bearing 8 is made to turn on a pin 10 within the line of tread of the wheel, and the bearing 9 is made to slide in a slot 13 concentric with the pin 10, so that the half-axle can turn about the pin 10 and set itself radially to the rail. The body is supported on the beam 6 by a post 7, a ball joint 20, a spring 21, and a frame 23 formed with guides 24, 15 for the post 7 and beam 6. If the flanges of the wheels are inside the rails, the pins 10 are placed outside the lines of tread. In a modification, shown in Fig. 13, adapted for the conversion of existing rolling stock, each half-axle rotates in an external axle-box 41 and an internal axle-box 42, on which a bolster beam 40 is supported by uprights 43, 44. The axle-box 41 and the axle turn on a pivot 50. In another modification, shown in Fig. 17, the axle 55 is in one piece and works in a central axle-box 56, mounted in an upright 57 and guided by a post 58 and a transverse slot 59 in the framing which supports the vehicle. The wheels, in this case, have external flanges and are connected by elastic spokes to hubs 61 which can turn on the axles when going round curves. The brakes are applied to the tops of the wheels, and the brake levers are arranged to permit the turning of the axle-trucks. The air reservoirs for the brakes may be carried on the axle-trucks.

Abstract: 9227. Prinz, F. April 23. Smoke and fumes, treating.-Relates to apparatus of the type composed of a rotary drum provided with a series of radial tubes or branches, of porous material, closed at their outer ends, and a collecting- trough placed within the drum, into which the dust deposited in the radial tubes is delivered. As shown in Fig. 1, the drum 4 is mounted to rotate in standards, and is composed of staves 6 united by tongues and bands 7 ; the tubes 11 are secured in the openings in the drum, and are tied together by rings 15 which are supported by radial rods 17 ; the trough 22 is supported by brackets 56 from the standards and is provided with wings which are pressed by springs against the wall of the drum, so as effectually to cut off the trough from the drum. Above the trough and between the tubes are mounted the rotating spindles 32, which carry beaters to act upon the tubes as they pass over the trough. The beaters may consist of rods 33, linked to the spindles, which fly outwards under the influence of centrifugal force ; or, as shown in Fig. 8, the spindles themselves may be made oval in section. To assist the action of the beaters, a suction pipe 57 may be led from the trough to the fan 57<a> which delivers the dust-laden air into the apparatus. When used to remove unconsumed solids from the products of combustion of furnaces, the pockets should be made of asbestos &c.

Granted: 1904-04-28
Abstract: 9862. Manley, G. May 1. Gas cocks; plug cocks; piston v a l v e s; actuating valves and cocks.- In order that the flow of gas to a burner may be regulated so as to give a full, or pilot light as desired, a gas cock is constructed with a sliding and rotatable conical plug b, the stem c of which projects through a stuffing-box in a casing a, and carries an operating milled head d, by which the plug can be drawn out, as shown, to allow a full supply of gas to pass through an inlet f, to an outlet g, which is connected to a burner. The plug b is made hollow, and is closed at its inner end by a perforated plate e, held in place by rolling over the edge of the plug b. When the inner end of the outlet g is closed by pushing in the plug b, only sufficient gas passes through the perforations in the plate e, and through a lateral passage, as shown, in the plug b, to the outlet g, to maintain a pilot light. The stem c carries a projection h, which works in a groove in the front part of the stuffing-box, and which acts as a guide during the sliding movements of the stem c, a lateral groove being provided in the front of the stuffing-box to receive the projection h, when the plug is rotated so as to entirely shut off the supply of gas. In another form, the provision for preventing rotation during the sliding movement of the stem c, and for entirely shutting-off the gas, is dispensed with, so that the device can only be used as a regulating-cock.

Abstract: 6148. Harber, W. F. March 14. Toy animals; dolls ; walking toys ; ropes or cords, suspended, toys travelling on; games played with model animals, puppets, &c.-In constructing a toy, two of which may be used in a competitive game, a cord, string, wire, or chain S, Fig. 3<c>, is passed through a device consisting of a metal tube T, which oscillates about a pin P in an opening O in a piece of millboard B, Fig. 1, shaped in the form of a doll, animal, or in any other manner, and shod with metal clips M<1> containing wheels W, which rest on a floor, desk, or other surface. The device is secured to the doll by a disc M. One end of the string S is fastened to a skirting or other fixing, against which the doll reclines, and by alternately tightening and slackening the string, the doll falls forwards and then assumes a nearly vertical position again, progressing, by a succession of such movements, along the string, any tendency of lateral motion being prevented by fixing the device above the centre of gravity of the piece of millboard. By raising the end of the string, the doll is made to gravitate backwards along the string, or it may be made to return by a succession of movements similar to those used in the forward action. A half tube only may be used instead of the tube T ; or, the latter may be formed with a stem pivoted about the pin P, and may or may not contain a small wheel under which the string S passes, while, instead of the disc M, the pin P may be passed through the millboard B, or through a metal clip, and clinched. In another form of device, the string S is passed through holes at each end of a bar, or at the ends of the upper part of a triangular-shaped frame, pivoted about the pin P, the frame being with or without small guiding- wheels for the string. In a still further modification, the string S is passed through an upper projecting part of a metal eyelet similar to those used in boots, except that the lower portion only is clinched, as shown in Fig. 7<c>.

The sliding latch-bolt shown in Fig. 2 has a circular head part 1, and a shank provided with flats 11, 12, Fig. 4, and terminating in an enlargement, which engages in a slot 8 in a laterally-projecting portion 9 of the lath part 2, operated by the follower on the knob spindle. A lever-plate 15, Fig. 3, pivoted at 18 to the cover-plate 14 of the lock case, engages with one of the flats 11, 12. By means of the projection 16, working through a slot in the cover-plate this lever-plate may be raised out of engagement, thus admitting of the reversal of the latch-bolt by its rotation through a half-revolution. The lever-plate, when returned, retains the bolt in its reversed position. The latch-bolt is pressed outwards by a spring bearing on the enlarged end. The lever-plate may be pivoted to the bottom, instead of to the cover-plate of the lock case. Also the lever-plate may be replaced by a stamped or other projection on the inside of the cover arranged so that the bolt may be rotated when the cover is unscrewed a little away from the bottom of the lock case. In a further modification, spring tongues engage with longitudinal grooves which replace the flats previously described. Instead of the flats 11, 12 being close to the head of the bolt, they may be formed on the enlarged end.
