Abstract: 21,974. Griffiths, W., and Bedell, B. H. Oct. 31. Electric railways and tramways on surface contact or similar systems. Collectors. - Relates to collectors for electricity used on electrically propelled or lighted vehicles, locomotives, cranes, &c., which receive current from magnetic conductors temporarily or permanently connected to the supply mains. The invention is especially intended for surface-contact or similar systems, so that the contacts may be placed level with the road. The collectors consist of movable pieces b b<1>, b<2>, of magnetic material connected to the poles of a magnet a carried by the car in such a manner that they are attracted by the road contact studs or rails c, so that they only come into contact with the parts from which current is taken. As shown in Fig. 1, the pieces b are slotted to work over fixed pins d, and are normally held up by springs e in the #-section magnet pole a. They may, however, be made as T-headed plungers, or as arms pivoted in or on the magnet and held up by spiral or flat springs or as U-shaped pieces embracing the pole. They may also be furnished with rollers at their lower ends, and non - magnetic plates &c. may be placed between them and the carrying-magnet to prevent sticking.

Title: Improvements in Printing Machines.
Inventor: NEWTON HENRY EDWARD
Filed: 1901-11-12
Granted: 1901-12-14
Abstract: 22,837. Newton, H. E., [Hoe, R.]. Nov. 12. Cylinder machines with plane printing-surfaces; rotary machines. -Relates to tripping-mechanism for preventing the operation of the impression cylinder of cylioder or rotary machines under certain conditions, by holding or stopping it in its inoperative position. Fig. 2 shows part of a cylinder machine, in which the cylinder is raised and lowered out of and into operative relation with the reciprocating bed, by means of rods 5 connected with the bearings 3 of the cylinder shaft 4 and operated by a usual form of toggle mechanism 8, 9. The toggles 8, 9 may be operated in a usual manner by a gab hook 14 engaging a pin 15 on a lever 16 pivoted at 17 and operated by a cam-groove 19 in a cam 18 on the shaft 20. The shaft 20 is driven to operate the toggles, and raise and lower the cylinder, as normally required during printing. To arre-t the operation of the toggles when the cylinder is in its raised (inoperative) position, the gab hook 14 is lifted from the pin 15 by a pin 25 on a lever 22 engaging a flanged piece 26 on the gab hook. The lever 22 is set by the operator so as to be operated by the machine only at the proper time. On the lever 22 is a pin or roller 28 which, in the normal operation of the machine, runs inside an annular guard on the cam 18. The guard has a gap through which the roller 28 must pass out before the lever 22 can be operated to raise the gab book. The lever 22 is set so as to pass out of the gap by a rod 29 pressing through a spring 36, on the arm 23 of the lever, when the rod 29 is operated, as by depressing a bell-crank treadle lever 37, 38. A catch 40 may be provided to hold the lever 38 depressed to render the cylinder inoperative for any desired time. When the gap in the guard permits, the spring 36 moves the lever 22, and the roller 28 is next engaged by the cam 41 and the gab hook lifted. The cam 41 is formed in one with the guard. A locking-lever 50 may be provided for engaging the lever 22,23 and holding it in its raised position. The lever 50 is pivoted to the frame, and has a rod 56 pivoted to it passing through an arm 55 on the rod 29. The roller 28 is preferably mounted to yield in case it should engage the guard instead of passing over it to the cam 41. The roller is mounted to slide axially in the arm 22, and is held in its outer position by a spring. The ends of the guard are inclined, so that if they engage the end of the roller 28 they press it inwards. Other mechanism for lifting and controlling the hook 14 in the manner described, may be employed.

Title: Improvements in Means for Transmitting Fluid under Pressure.
Inventor: HALSEY WILLIAM SMILEY
Filed: 1902-12-12
Granted: 1903-02-19
Abstract: 27,477. Halsey, W. S. Dec. 12. Transmitting power.-Relates to apparatus for transmitting fluid under pressure from a supply reservoir to a device in which it is to be employed. The fluid reservoir or feedpipe 1 is surrounded by a movable receiver 2 provided with means for operating the supply valves, and arranged so as to conform to the curvature of the reservoir. The receiver is packed at each end to form fluid-tight joints with the reservoir, and is provided with tapered faces 4 for actuating the valves 5. These valves are arranged in pairs, and control opposed supply openings 5<a> formed through bushes screwed into the valve casing, these bushes acting as seatings and also as supports for guide-pins 5<b>. The valves are pivoted to the ends of a tappet lever 7 operated by a T-headed tappet 6 arranged to slide in a bush in the casing. The shoe 6<c> on the end of the tappet projects into the receiver. A flexible guide casing 8, which may be provided with saw cuts to increase its flexibility, is fixed within the receiver 8, and at points adjacent to the ends it is formed with inclines 8<c> to operate the valves 5. Holes in the casing 8 register with the supply openings 5<a>. The receiver is supported by brackets provided with wheels or rollers traversing a race. A passage 16 leads from the receiver to the point of transmission of the fluid pressure. When, in the longitudinal movement of the receiver, the leading inclined face comes against the shoe 6<c> of one of the tappets, the lever 7 is raised and the valve opening into the receiver is opened, the other valve being kept closed by the pressure within the reservoir. As the receiver moves, the shoe 6<c> slides down the inner incline 6 and the valve closes, but both valves are opened upon the engagement of the incline 8 on the casing 8 with the shoe. The valves are kept open for the delivery of fluid until the rear incline 8<e> passes under the tappet, when the movements above described are reversed. The flexibility of the casing 8 adapts the receiver to the curvature of the reservoir, but the receiver may be made of a bent form approximating to the curvature of the reservoir, or it may be built up of a number of sections connected together by flexible steel rods. Instead of the casing 8, guide strips and a tappet piece may be connected to the receiver and take a bearing upon the reservoir.

Title: Improvements in Prepaid Gas Meters.
Inventor: PINCHBECK JOHN
Filed: 1902-12-31
Granted: 1903-11-12
Abstract: 28,911. Pinchbeck, J. Dec. 31. Gas meters.-Relates to improvements in the meter described in Specification No. 5656, A.D. 1899. A square shaft f, having engagement with a sleeve k which is turned by band after prepayment, and screwing into a sleeve nut e which is geared to the meter, carries a loose cross-arm f<2>, which bears on a horizontal guide-bar f x x and on the lever g of a valve. The valve, which closes by its own weight, is accordingly open whenever the cross-arm is away from a notch g<1> near the fulcrum h. Actuating-mechanism; coin action. -A disc o having an external knob o<3> for turning it, bears radial and lateral cheeks o<4> to hold the coin in a radial slot and in engagement with a crownwheel l at the end of the sleeve k. After a partial rotation, the coin strikes a stop r' on a fixed disc r, and falls away. The pawl l<1> prevents rotation of the crown-wheel in the wrong direction by the handle, and also rotation in the possible direction owing to friction between the sleeve-nut and screw. When, owing to the maximum prepayment being made, the shaft has been screwed fully into the sleeve, a bent finger f<3> on the cross-arm f<2> pulls a lever s, which thrusts a rod t in the path of a lug on the coin-receiving disc, so that it cannot be turned back to take another coin till gas has been delivered sufficient to let the lever s fall again to its stop. Coin-discharging mechanism.-The coin is kept in the pocket by a flange r<x> on the fixed disc r, and drops out at the end of the flange after striking the beforementioned stop r<1>, which is nearer the centre of the disc. The disc can be turned and secured by a screw r<2> through any one of a series of holes which determine the unit of supply.

Abstract: 4624. Dabell, A. F. Feb. 27. Conveyers; shoots; inclined platforms for casks and the like.-Relates to an automatic turntable for altering the direction of motion of goods during transmission, such as barrels when rolling down an inclined plane. The turntable consists of a frame B pivoted at B<1> to a piston C working within a fixed cylinder D and resting on the conical point of a sliding pin F, to which are attached counterweights G<2> by means of cords passing over pulleys. The piston C is provided with helical slots C', which are engaged by rollers on the cylinder, to cause it to rotate when depressed. The barrels or other goods pass down the inclined way A on to the turntable ; the weight causes the turntable to rotate and deliver them on to a second way placed at right-angles to the way A, the turntable being returned or raised by the counterweights G'. A bracket C<2> comes into contact with a stop D' and limits the motion of the turntable, and a lug B<3> comes into contact with an inclined plane D<3> to tilt the frame B. The premature tilting of the frame is prevented by a roller resting on a support. Stop mechanism is provided to prevent the barrels from passing on to the turntable while it is in its lowered position. A weighted rock-shaft J has arms J' for stopping the barrel, and also an arm J<2> which is engaged by a pawl K when the turntable is in its lowered position. When the turntable rises, the pawl K is tripped by the arm L and is held out of action by a second pawl M, as shown in Fig. 4. The pawl M is tripped by one of the stop arms J<1> when the barrel passes on to the turntable. The details of the apparatus may be modified; the helical slot may be replaced by helical ribs, and the counterbalancing may be effected by weights and levers or springs, etc.; or the piston may be fixed and the motion taken from the cylinder or from a frame working in guides upon the piston. The goods may be delivered to the turntable by an endless conveyer, and taken thence by an inclined way or by another conveyer.
