Patent GB-190013721-A (GB)
Title: Improvements in Systems of Electric Motor Control.
Filed: 1900-07-31
Granted: 1901-03-30
Abstract: 13,721. British Thomson-Houston Co., [Perry, C. L.]. July 31. Switches. - Relates to a motor-control system for electricallydriven vehicles &c. in which the controller comprises a number of separately-a c t u a t e d contacts, with actuating-coils in connection with a master, controller, the main object being to enable the several actuating-coils to be efficiently operated at full line potential. The actuating-coils are so arranged that, in certain positions of the controller, a predetermined number of them may be connected directly in series across the mains, and are so proportioned that, when thus connected, they will take only the requisite amount of current ; in the other positions of the controller, when a smaller number of contacts are to be actuated, the corresponding number of actuating-coils is connected in circuit with a sufficient resistance to limit the current to that which would flow when the several coils are connected in series. Fig. 1 is a diagram showing one arrangement which may be adopted in connection with a series-parallel controller. The several actuating-coils S, P, P, T<1>, T<1>, R<1> to R<6>, R<8>, R<8> are connected permanently in series with one another, with the exception of the actuating-coils S, P, P of the series and parallel contacts, which are arranged in branch circuits at one end. In the series position of the master controller, the terminal 9 is connected to one side of the power circuit, while the terminals 11 to 17 are successively connected to the other side ; in the parallel positions, the terminal 10 is connected to one side of the power circuit, while the terminals 11 to 17 are successively connected to the other side as before. The resistances R<a> and R<b> to R<@> are so proportioned that, whatever the number of actuating-coils in circuit, the flow of current is approximately the same. Figs. 2 and 3 show a preferred arrangement, in which the series of actuating-coils is divided into two distinct sets. The terminals 18 and 19 are connected permanently to one side of the power circuit, while the remaining terminals 9 and 10 and 13 to 17 are connected at the proper times to the other side of the circuit through the contacts of the master controller. Fig. 8 is a diagram of one of the controller contacts with its actuating-coil c and blow-out coil d. The movable contact e is carried by a pivoted arm g, and is brought against the fixed contact f by the attraction exercised by the coil c upon a movable core h. In the final series and parallel positions of the master controller, a resistance, previously short-circuited, is thrown into circuit. The short-circuiting device may be arranged in connection with the last controller contact, as shown in dotted lines in Fig. 8.

Patent GB-190119966-A (GB)
Title: Improvements in Machines for Covering Boxes.
Inventor: SMITH PHILIP STANLEY
Filed: 1901-10-07
Granted: 1902-08-21
Abstract: 19,966. Smith, P. S. Oct. 7. Making boxes.-In covering boxes with paper &c. blanks, shaped as shown in Fig. 24, apparatus such as that shown in Fig. 1 is employed. The box, having attached to its bottom the covering- blank, is placed on a former G, carried by a plunger F<1>, which is reciprocated vertically by the cam F<8> on the vertical shaft 8, through the pivoted lever F<2>. The former, on its descent, carries the box between spring rollers B, which serve to fold the side flaps X' of the covering-blank against the sides of the box, Fig. 25. The flaps X<2>, which are only pasted at the edges, are held by brushes, while the corner flaps X<3> are turned in against the ends of the box. The flaps X<3> are turned in, Fig. 27, by reciprocating wipers operated, through suitable mechanism, by the cam D<5>. The further descent of the former brings the end flaps of the blank against rollers by which these flaps are folded upwards and attached to the corner flaps X<3>, Fig. 28. Both sets of rollers are mounted on adjustable slides surrounding the aperture in the table through which the former passes. Mounted above the rollers are plates by which the flaps of the blank, which are disposed to curve downwards, are guided into position before being operated upon by the rollers ; and under the rollers are flexible plates which on the ascent of the former come between the former and the rollers to prevent the latter from receiving any paste from the former. Brushes &c. may be substituted for the rollers. When the flaps are thus folded against the box, the former, on its further descent, causes the bottom of the box to abut against a spring plate L by which the bottom of the blank is securely attached to the bottom of the box. Clips H, carried on a frame H<2> resting on the former G, and provided with guide-rods H<3> passing through lugs on the plunger-guide F, serve to hold the box on the former in the first instance. As the former descends the clips are disengaged from the box, the descent of the frame H' being arrested by collars on the rods H<3> abutting against the lugs on the guide F. When the former ascends, the covered box is thrown off by stripper rods J, which move through guides in the former and piston, and are arrested by spring friction-pins until the plunger reaches cross-bars connecting the rods J at the top and bottom. For large flimsy boxes, supplementary flexible strippers K, attached to the slides carrying the lower rollers, may be used, The driving-shaft M, which is geared with the cam shaft S by worm gearing, is automatically thrown out of gear by means of a suitable clutch &c. device ; or it may be thrown out of gear by operating a hand-lever, and is again put into gear by working the treadle M<18>. When the box is removed from the apparatus, the top edges of the blank are turned in by hand.

Abstract: 20,988. Bailey, W. O. Oct. 19. Surfacing and polishing; bevelling glass &c. The glass &c., the edges of which are to be treated, is supported on the easel c pivoted at d to the frame a. The glass is pressed down by a clamp o, the ends of which are guided in brackets p. The clamp is of box-like structure, and is actuated by a hand-wheel on the spindle p<4> which rotates the screws p<1> by bevel gearing. The screws engage with nuts on the clamp. The inclination of the easel may be adjusted by a hand-wheel c<6> on a spindle carrying a worm c<5> actuating a toothed wheel gearing with the rack c' on the easel. The easel has an extension consisting of vertical bars t and cross-bars t' carrying buffer studs. The surface of the easel is also provided with spring buffer studs r, such as those described in Specification No. 18,540, A.D. 1897. The stems r<2> of the lowest row of studs are locked by blocks r<1>, which are forced down by the inclines s<1> on the bar s moved laterally by a screw s'. The grinding-wheel g and the medium-feeding apparatus, described in Specifications No. 16,995, A.D. 1899, and No. 3269, A.D. 1898, are carried by a carriage f reciprocated by a screw h and half-nut h<1> readily disengaged. The grinding-wheel spindle g<1> carries a bevelwheel gearing with a second bevel-wheel k, which slides without turning upon the main shaft i arranged parallel to the easel c. The grinding- wheel can also be slid along its spindle by means of a hand-wheel, nut, screw, and connecting-rod. The channel m of the medium-feeding apparatus is kept always close to the wheel g by connecting the channel by an arm m<2> to a rock-shaft m<3>, which is also connected by an arm to a collar on the wheel. The mixer and conveyer shafts are driven from the main shaft by bevel gearing. An adjustable ledge for temporarily supporting the glass plates while being placed on the easel is described. The ledge is pivoted to the easel and actuated by hand levers. The track e is protected from the fluid medium by travelling aprons or waterproof covers attached to the ends of the carriage f and suitably counterbalanced. The Provisional Specification states that the carriage f may be actuated by a rack and pinion and bevel gearing.

Title: Improvements in Electric Arc Lamps.
Filed: 1901-12-24
Granted: 1902-01-30
Abstract: 26,342. British Thomson-Houston Co., [Thomson, E.]. Dec. 24. Arc lamps.-In electromagnetic regulating- mechanism, two coils 14, 16, having different t i m e constants, are electrically connected in parallel with each other and in series with the arc; one coil 14 is stationary and produces a magnetic field, in which the other coil 16 is movable electromagnetically, to regulate the arc by mechanical connection with feeding-mechanism 18. A variation in current chiefly affects the part passing through the coil 16 having the lower time constant, and a prompt and strong movement of the feeding- mechanism may thus be obtained to correct the variation; the arc is rendered stable, and a relatively large proportion of the applied electric pressure may be used in it. In the form shown in Fig. 2, the stationary coil 14 of high self-induction surrounds a tubular central limb of a three-legged magnet 13 ; the other coil 16, of higher resistance and lower self-induction, is movable vertically on the central limb, between the side ones, and is attached directly to a central tube carrying a crutch 18. In another form, the stationary coil is placed on a horse-shoe magnet; the movable coil surrounds a stationary core in the field of the magnet, and turns on pivots with an arm which is linked to a dash-pot and to a clutch for the upper carbon.

Abstract: 479. O'Donnell, J. P., [Dodgson, F. L.]. Jan. 7. Semaphore &c. signals ; signalling &c. between trains. -Relates to pneumatic systems for operating railway signals, points, crossing-gates, &c. The operation of the signal, switch, &c. is effected, through a cylinder and piston 6, 7, or a flexible d i a - phragm, by compressed air or gas supplied from a bottle or other container 2 located adjacent to the signal &c. The supply-pipe 3 is provided with a reducing-valve 4, and with an electrically-controlled valve 5, which may be of the type described in Specification No. 6553, A.D. 1901. When the container 2 is exhausted, it may be re charged, or it may be removed and a charged container substituted for it. In the arrangement shown, the operation is controlled by a track relay 14, which, when the section is unoccupied, closes the contact 21 in the operative circuit 19, 20 of the valve 5, so that pressure is admitted to the motor 6 to lower the signal. When the section is occupied, the relay is short-circuited, the valve 5 is closed to the supply, the motor 6 is opened to exhaust, and the signal goes to danger ' by gravity. To avoid waste of gas, an electric " slot " mechanism may be employed to hold the signal at ' safety ' so long as the controlling - circuit is closed. The Provisional Specification also states that the controlling- current may be set up by a lever or contact-maker in the signal cabin.
