Title: Improvements in Adjustable Seats and Desks.
Inventor: BERFORD VICTOR
Filed: 1899-08-31
Granted: 1899-10-07
Abstract: 17,640. Berford, V., Dunn, G., and Wilson, T. Aug. 31. School desks and seats; desks ; seats.-The desk A is carried by a rod A' adjustable in a standard B. With the screw-threaded part b of the standard B engages a chambered nut D containing a pair of serrated clamping-dogs E. By screwing or unscrewing the nut the action of the inclined parts d, e clamps or unclamps the rod A<1>. On a shoulder and turned bearing F works a sleeve slotted at f to receive a bracket G carrying the seat g<2> and back H<1>. The socket and bracket have corresponding serrations, and by moving the arm g in the wide lower part of the slot f the parts can be disengaged and the seat bracket adjusted in elevation. The base of the standard has internal projections b', which engage under a flange b<3> on a plate secured to the floor. By rotating the standard till the projections register with certain recesses, it can be removed,

Title: Improvements in Block Signalling for Railways.
Inventor: JELFS GEORGE HENRY
Filed: 1899-11-14
Granted: 1900-09-29
Abstract: 22,708. Jelfs, G. H. Nov. 14. Signalling-instruments ; controlling and locking signals; interlocking; indicators and repeaters, signal. - The miniature semaphore a of the block instrument is provided with two arms b, which make contact with one or other of the contactsprings d, c in both indicating positions of the semaphore. The ordinary semaphore is operated by a divided pull, which is connected and disconnected as described in Specification No. 14,789, A.D. 1899. The electromagnet g, which effects the connection of the pull, is connected with the contact d, while the contact c is connected with the contact-lever p, arranged to close the circuit of the releasing- electromagnet m of the block instrument of the rear section. The electromagnet m controls the circuit of the subsidiary electromagnet h on the signal post. On receipt of the line clear' signal from the section in advance, the miniature signal a is lowered, and completes, with the spring d, the circuit of the electromagnet g, which is carried by the bar e. The electromagnet g, by attracting its armature j, rotates the cylinder k and locks the slide i in the notch of the bar f, so that, by operating the bar e, the bar f is also operated to lower the ordinary signal. In the upward movement of the bar e, the arm n moves the lever p into contact with the connection from the electromagnet m, the lever p being locked by the lever q dropping behind it. When the train leaves the station, and the departure signal is sent to the section in advance, the reply from that section causes the miniature semaphore a to move to 'danger' and connect with the contact c. This completes the circuit of the electromagnet m, which releases the commutator r in the ordinary way. The armature of the electromagnet m also closes the contact l and completes the circuit of the electromagnet h, which raises the catch lever q and allows the contact-lever p to be returned by a spring to its normal position. When a train does not travel on beyond a certain station, sanction must be given from the section in advance for the admission of a following train from the section in the rear. In this case, the operating-lever t carries the electromagnet s and a crosshead, the movement of which is controlled by dash-pots u, or by springs. The magnet s is energized by the operator of the section in advance holding down his bell plunger for several seconds, during which period the lever t is operated against the delaying resistance of the dash-pots &c. The circuit of the electromagnet m, which releases the commutator r to enable the line clear' signal to be given to the section in the rear, is closed at the contacts x by the armature w, which is raised by the electromagnet s. If the current from the section in advance is not sufficiently prolonged, the armature w falls and does not close the contacts x. The resistance to the operation of the lever t is intended to prevent the operator from making his releasing-contact without due consideration.

Title: Improvements in the Manufacture of Metal Tubes.
Inventor: BECK ARTHUR EDWARD
Filed: 1900-03-29
Granted: 1901-03-29
Abstract: 5927. Beck, A. E. March 29. Metal pipes and tubes.-Iron or other metal tubes of a constant or variable diameter are reduced in diameter more than the internally-supporting mandrel ordinarily permits by arranging rollers B, B<1>, C, C' behind the gapped or pilger rolls A, A<1>, and the tubes are stepped by not being completely passed through all the rolls. Instead of supplementary gapped rolls, continuous rolls or adjustable dies may be used, and these may be alternately advanced and withdrawn or opened and closed by known mechanical means, to effect a reduction or tapering in the tube.

Granted: 1900-05-26
Abstract: 6745. Thompson, I. M. B. April 10. Figures &c., plotting.-Relates to a mathematical chart for plotting regular polygons and the like, and so producing figures and patterns. Fig. 1 shows about a quarter of the chart. A series of equidistant concentric circles are described, and radial lines are drawn inclined from a common starting-line x-x at the required angles to give the angular points of regular polygons. For clearness, these lines terminate on different circles. Thus the lines for the pentagon, decagon, &c. terminate on the first circle, the lines for the square, octagon, &c. on the second, and so on, the lines being numbered at their outer extremities 20, 5, 20, 10, 20, 5, ..... 4, 32,16, 8, 32, 4 .... as indicated. The circles are distinguished by numbers relating to the number of sides of the polygons to which they are allotted, and also by small letters a, b, c, ... s. Round the outer circle the space is divided, as shown, into squares, with one diagonal of each marked, the sides of the squares being equal to the distance between each pair of adjacent circles. The squares are also marked with reference letters, large and small. These squares and their diagonals are useful for drawing tangents to the circles, lines at right-angles intersecting at given points &c. The whole diagram is surrounded by measuring-scales.

Abstract: 824. Smyth, W. H. Jan. 12. Mechanical stoking.-Fig. 1 shows a vertical section, and Fig. 2 a side elevation, of a mechanical stoker which can be fitted to any ordinary boiler front and which, when forming one of a series driven by a single motor, can be thrown out of action without affecting the others of the series. The coal is supplied to a hopper A, and is broken by a pair of corrugated rollers B, B<1>, which regulate the amount dropping into the distributing- fan C. This fan throws the fuel into the furnace under the control of a plate E, which is rocked on a pivot by a cam on the shaft H, acting through a rod J and arm. The fan is driven by a rope Q, which is pressed into the grooved pulley F by a spring-pressed pulley R. When the stoker is to be thrown out of use, the pulley R is held away from the pulley F by a latch U. The rollers B, B' are geared together, and are rotated by a pawl-andratchet gear, shown in Fig. 2, and actuated by a crank on the shaft H.

Granted: 1903-03-26
Abstract: 7486. British Thomson-Houston Co., [Erben, H. F. T.]. March 27. Cut-outs; switches; transformers. -Relates to speed-controlling devices for dynamo - electric machines whereby such machines are stopped should the speed exceed or fall below a predetermined limit, and is especially applicable to boosters supplying electric railway systems. A centrifugal apparatus is employed to close the trip-circuit of a circuit - breaker when the speed is too high or too low. Figs. 1 and 2 show the construction. Adjacent to the end of the shaft of the booster is a support I carrying two conducting-rings K, K<1> insulated from the support and from one another but connected to the tripcircuit. On the end of the shaft are mounted on pivots N two weights 0 connected by adjustable springs P. At the centre of the shaft is a stud R on which is pivoted an arm s which can be turned to take the position shown and hold the weights in an intermediate position. When the shaft rotates, the weights are thrown outwardly, allowing the arm s to be pulled away from the catches o, o<1> so that, should the speed drop, the weights are drawn inward and the heel pieces q engage the rings K, K<1> and close the circuit of the cut-out. Should the speed be excessive, then the weights are thrown out against the rings and the circuit also closed. The arm s is re-set by introducing a tool through the opening t in the cover T. In a modified construction, one ring K only is employed.
