Patent GB-190700453-A (GB)
Title: Improvements in Controllers for the Trolley Poles of Electric Cars.
Inventor: EDWARDS ALFRED JOHN
Filed: 1907-01-07
Granted: 1907-10-03
Abstract: 453. Edwards, A. J. Jan. 7. Electric traction on the overhead - conductor system. Collectors.-Relates to the means described in Specification No. 19,150, A.D. 1906, for automatically retracting the trolly poles of electric cars. According to the present invention, the sleeve g is extended to the bottom of the case a so as to rest normally in the bearing g<1>, and the control rope l is attached to a rod p carrying a cone - shaped weight r, adapted to move freely within the sleeve and serving to keep the trolly rope taut. This weight is formed with projecting arms s which work in slots t formed in the sleeve. A helical spring u, surrounding the rod p, rests on the cone weight and carries a bar w having pivoted depending hooks x. Normally, the rod p and its appendages work freely in the sleeve ; but, when the rope is jerked quickly, the spring is compressed, and the cone surface of the weight forces the hooks x into engagement with the sleeve g. The movement of the sleeve then liberates the weight b, which, in falling, engages with the arms s and retracts the collector. It is stated in the Provisional Specification that the upper surface of the cone weight is grooved at points beneath the hooks and that, where the length of the sleeve is not sufficient to allow for the necessary free movement of the rope, the rope may be looped through the top of the rod and its free end secured to a fixed point on the car.

Inventor: BARRETT WILLIAM
Filed: 1907-01-29
Granted: 1908-01-16
Abstract: 2184. Barrett, W. Jan. 29. No Patent. granted (Sealingfee not paid). Spring surfaces.-A railway-carriage &c, seat or surface is formed of an angle-iron frame a, in which are arranged coiled springs c, held in com. pression either by a skeleton frame of transverse and longitudinal rods f attached to the underside of the frame a, or by a covering h of fabric. The outer series of springs rests directiy upon the horizontal portion of the angle-iron frame, and the upper and lower convolutions of each spring are stayed by cross-pieces of the kind described in Specification No. 4545, A.D. 1904, so as to prevent lateral distortion. Rigid pieces g, with three or more hooked ends instead of two as in the Specification above referred to, engage the upper or lower coils of several adjacent springs so as to prevent distortion, and also serve to suspend the inner springs from the outer series. The outer springs are connected to the frame by eyed bolts d, as shown, while the rods f of the skeleton frame are secured by nuts d<3> on the same bolts. The covering h is provided with eyelets h<3> which pass over the bolts d and are secured by nuts h<4>. The construction facilitates the disconnexion of the parts for cleaning.

Title: Improvements in or relating to the Cooling or Ventilating of Alternating Electric Current Transformers.
Inventor: BERRY ARTHUR FRANCIS
Filed: 1907-03-08
Granted: 1907-07-04
Abstract: 5654. Berry, A. F. March 8. Transformers, such as are described in Specifications Nos. 2096 and 11,363, A.D. 1904, are cooled by an arrangement comprising a fan driven by an electric motor for inducing a current of air to,. circulate through or around passages or the windings of the transformer. As shown in Fig. 1, the transformer a, of cylindrical form and arranged vertically and d provided with ventilation passages b, is supported upon a. grid c, and is surmounted by a hood or casing d, which converges upwardly and carries an electric fan f beneath the air outlet e. The fan; which may be of any convenient type, is connected across one or more of the turns g of the low-tension winding g<1>, the voltage of which suffices to start the fan with the lightest load for which the transformer is designed to work, so that it is brought into operation automatically with the starting of the transformer. Or, the fan may be so connected that sufficient current will not flow through the motor to effect starting until a certain predetermined load is exceeded, when it will automatically come into operation.

Title: Improvements in Movable Bed Web-printing Presses.
Inventor: COX PAUL FLEMMING
Filed: 1907-03-14
Granted: 1908-03-14
Abstract: 6232. Cox, P. F. March 14. Cylinder machines with plane printing-surfaces; delivery apparatus ; feeding - apparatus for webs ; inking - apparatus; tripping - arrangements.-In a web-perfecting flat-bed machine, each bed A, B has two sets of formes 1, 2, 1<a>, 2<a> and corresponding impression cylinders a, a<1>, b<1>, b, by which alternate portions of the web are printed, thus reducing the necessary travel of the bed by about one-half. In addition, the formes are placed with their long edges transversely to the bed, thus further shortening the travel. The two beds A, B are preferably reciprocated by horizontally-moving connecting-rods J, J, driven from gearing J<2>, J<3>, &c., as the whole machine is thus kept low and is easily reached, but they may be driven by vertically-moving rods operated in a similar manner. The web is fed from a roll W past feed-rolls and a guide-roll g to the cylinder a, thence by adjustable guide-rolls g<1>, g<2>, to the cylinder a<1>, round guiderolls g<3>, g<4>, to coaxing-rolls H, H<1>, which are suitably driven to help the web forward past guide-rolls h<4>, h3 to cylinders b, bl for perfecting ; the web then passes to delivery - apparatus I, slitting-rollers L, and web-turning and associating devices L<2>. The whole web receives a continuous forward feed, but as the motion of the bed is not in all cases uniform, the guide-pulleys g, g<3>, h3, h are in some cases operated through a rod k<2>, bellcrank K', and cam K to compensate for the slight variation in speed of the web past the impression cylinders. On the return stroke of the beds, the impression cylinders are all tripped through levers c<1> operated by a single rod C' and cam-actuated lever c, the rod C' being disconnectible from the lever c to hold the cylinders in the tripped position if desired. One inking-apparatus is provided for each bed, a separate inking-roll e' inking each set of formes. The impression cylinders may be of the stop - cylinder, multi - revolution, oscillating- cylinder, or other type.

Title: An Improved Electrical Block Signalling System for Railways.
Inventor: BROWN GEORGE HERBERT
Filed: 1907-05-08
Granted: 1908-05-07
Abstract: 10,687. Brown, G. H. May 8. Signalling-systems ; contacts, electric signalling to cabins.-An improved form of the system described in Specification No. 2413, A.D. 1907, comprises three lamp signals on the engine, namely a white lamp which is energized while the system is in working order, and green and red lamps. Two insulated contact-pulleys b are mounted under the engine and make contact with conductors laid on the track at the ends of the block sections. When the engine is not running over these conductors, the pulleys are held down by springs and make contact with brackets f<1>, one of which is connected to the white lamp. So long as this condition obtains, the lamp is energized as part of the circuit including also the dynamo, the pulley frame e, the bracket f<1>, and the engine frame. When the engine is passing from one section to the next, pulleys make contact with the respective conductors, and being pressed up break the white lamp circuit and through the brackets f the circuit of the green lamp or the circuits of both red and green lamps are closed. If the section is clear, the track conductors are not electrically connected, and only the green-lamp circuit is closed, including the dynamo, the bracket e, the green lamp, and the engine frame. If the section is not clear, the track conductors are connected, and the red-lamp circuit is also closed, including the dynamo, the bracket e, the track conductors and their connexions, the bracket e, the bracket f, the lamp, and the engine frame. The pulleys are protected by the horns h and brushes h<2>, Fig. 2. If an obstruction on the track is met, and passes the brush h<2>, it swings the lever i and thereby releases one or other of the spring arms k, k<1>, which makes contact with a stop g<3>, and puts the red lamp in circuit and informs the driver.

Abstract: 28,587. Farquhar, M. C., and Hill, A. H. Dec. 30. Breech actions, sliding barrel and breech-block.- Relates to the invention described in Specification No. 7969, A.D. 1906. A spring M is compressed by the recoiling barrel A by means of rack gears B, C and D, E, a slide F, and a pin f<1>, or of a projection such as A<3> but longer. As the recoil starts, a catch J is pushed by a lug A<2> and locks the rear end of the spring M. At the end of the recoil, a lug A<3> abuts against a cushion spring. J<13> on a catch J<1> and pushes the catch into a recess g in the front block G of the spring M. When the barrel nears the end of its return, the catch J is released and the rear end of the spring M opens the breechblock by means of a link L, at the same time compressing the weak spring l. This subsequently closes the breech and returns the spring M to its original position, the catch J' having in the meantime been released by a spring J<14>.
Patent GB-190802769-A (GB)
Title: Improvements in Prepayment Electricity Meters
Inventor: HOOKHAM GEORGE
IPC: G07F15/00
Filed: 1908-02-07
Granted: 1908-12-17
Abstract: 2769. Hookham, G., and Holden, S. H. Feb. 7. Electricity, supplying; delivery mechanism.-Relates to the prepayment-meter mechanism described in Specification No. 28,006, A.D. 1902. According to the present invention, a smaller number of checks, which can therefore be of larger size than heretofore are employed, and instead of allowing them to fall into a drawer and then replacing them by hand into the check reservoir, they are lifted mechanically from the receptacle into which they fall and are placed in the movable beam as required. The checks g are contained in a trough f from which they are carried to the beam a when the coin-freed shaft o is turned by means of a lever k, which ends in a pocket h and is geared to the shaft by a sector m. A shield f is attached to the casing to prevent the check from falling out of the pocket, and a shield k<1> is attached to the pocket h to prevent the other checks from rolling out of the trough. The checks, by rolling down the beam, depress it, and are prevented from rolling off by one of the arms of a star-wheel c, which is so geared to the counting-mechanism of the meter that it makes a quarter revolution during the delivery of the quantity of electricity equivalent to one check, thus returning a check to the trough f from which it can again be transferred to the beam by insertion of further coins. A glass front is provided so that the number of checks on the beam can be seen. Coin action.-Normally the apparatus is in the condition shown in Fig. 4, and before inserting the coin, the shaft o is rotated in a clockwise direction till the nose of the cam 1 coming into contact with the tail of the lever 2 swings it over, thus moving the cylinder r into the position shown in Fig. 3. The coin is then inserted through a slot in the casing into a fixed shoot s within the cylinder r. The shaft o is then turned in an anti-clockwise direction thereby allowing the lever 2 to return the cylinder r, so allowing the coin to drop into a bottomless pocket s<1> upon an arbor v. Here the coin closes a central slot so that, when the lever t is operated by a lug on the shaft o, it presses the pocket s back into the position shown in Fig. 4, thereby raising a weighted detent w from a second lug u and allowing the full turning of the handle necessary to raise fully the check-lift h. Finally, the detent w is left resting on the right edge of the lug u, as shown in Fig. 4. If no coin is inserted, the lever t passes through the slot in the pocket and does not raise the detent w clear of the lug u, consequently there cannot be sufficient rotation of the handle to raise the check-lift into position to deliver a check. The tail y attached to the cylinder r prevents the insertion of a second coin while one is already in the mechanism.

Inventor: HOLDEN HENRY CAPEL LOFFT
Filed: 1908-04-23
Granted: 1908-09-03
Abstract: 8894. Holden, H. C. L. April 23. Field carriages; mountings. -Recoil apparatus for ordnance is provided with mechanism for controlling the run-out so that there is a definite position of rest for the gun. The invention is especially applicable to guns fire mechanically by means of a 'trigger or lever on a non-recoiling part of the mounting. The piston b working in the recoil cylinder c has a chamber a, into which the liquid flows through a passage e when the gun recoils. During run-out, the control ram d, which is tapered, enters the chamber a and gradually throttles the passage e until the position shown in Fig. 3 is reached, whereupon flats or grooves f on the ram, or a part reduced in diameter, serve to increase the throttling- area, and the gun then completes its stroke unchecked.
