Inventor: WHITTINGHAM GEORGE HERBERT
Filed: 1903-01-15
Granted: 1903-02-26
Abstract: 1033. Whittingham, G. H. Jan. 15. Motors, controlling.-Relates to means for cutting out resistance in starting motors. A clutch device, operated directly or indirectly by the motor, moves the contact-arm to cut out resistance, and releases it automatically at the desired point, the arm then being held by a retaining-magnet. Figs. 1 and 2 show one arrangement, in which d is the main switch, c the resistances, b the electromagnetic clutch, and k the retaining-magnet. The clutch consists of a cup-shaped disc q containing a coil i and formed with teeth q<1>, and an iron plate or armature t loose on the spindle. When the motor starts, the coil is energized and the plate t moves with the disc, so cutting out the resistances. When the arm u reaches the magnet k, the coil i is short-circuited and the clutch is no longer operative, the disc q rotating freely. When the switch d is opened, the arm u is returned by a spring v or other means to re-insert the resistances.

Title: Improvements in the Manufacture of Positive Electrodes for Secondary Batteries.
Inventor: RODERBOURG CARL
Filed: 1903-01-15
Granted: 1903-11-12
Abstract: 1088. Roderbourg, C. Jan. 15. Secondary batteries.-Relates to the method of avoiding the production of peroxide dust when handling secondary-battery positive electrodes, in which such electrodes are made similarly to negative electrodes by reducing a lead-peroxide coating into lead sponge by means of sulphuric acid, and are afterwards re-oxidized in the working of the battery, and consists in immersing the plates in the reduced condition until saturated in a bath containing zinc sulphate or other salt not harmful to the battery, such as those of sulphuric, phosphoric, boracic and silicic acids, in order that they may have their normal capacity when charged for the first time. Alternatively, the reduction of the oxide to the lead sponge may be carried out in the salt solution instead of the usual sulphuric acid. The treated plates may be dried and stored for some years, and retain the power of yielding their capacity after the first complete charge.

Patent GB-190303204-A (GB)
Title: Improvements in and connected with Trolleys and Trolley Poles for Electrically Propelled Vehicles and the like.
Inventor: TYERMAN ALFRED LAWRENCE
Filed: 1903-02-10
Granted: 1903-12-17
Abstract: 3204. Tyerman, A. L. Feb. 10. Collectors.-Relates to an automatic device for allowing the trolley poles of electrically-propelled vehicles to drop down clear of the trolley wire when the collector jumps the wire. Fig. 1 shows a side, and Fig. 2 a front end elevation of the trolley in its normal position, the pulley being on the trolley wire. The trolley wheel is mounted on the pillar C in the casing B, and is capable of a limited up and down, as well as a rotary, movement. The pressure between the trolley wire and pulley keeps the pillar C down against the spring G. When the pulley jumps the wire, this spring forces the pillar upwards and allows the spring H to throw the rod E rearwards. This rod, by means of the ropes I, thus lifts the sleeve L so that the two right-angled levers 0 liberate the springs K, as shown in Fig. 4. The trolley arm then falls clear of the wires, and is re-set by raising the arm. According to the Provisional Specification, the spring G is replaced by a forked lever, which supports the lower end of the pillar C and is fulcrumed on the piece which joins the casing B to the trolley arm. The other end of this lever is connected to the rope so that, when the pillar C rises, the rope becomes slack and liberates the springs K. Another arrangement of slip device is also described, in which, when the rope becomes slack, the sleeve L is raised by a spring inside, and, if required, a catch device is secured to the springs K, and the right-angled levers are so formed that when they are pressed against this device they will spread out of themselves. A method of re-setting the trolley by fixing pulley-blocks to the sleeve L and the trolley shaft is also described.

Abstract: 7159. Ransome, A. March 27. Sawing.-Relates to means for tightening a band-saw, canting one of the saw pulleys b<1>, traversing the table carrying the log a<1>, and moving the saw frame e up and down its guides. The bearings b<2> of one of the pulleys b<1> are fixed in slides, both of which are moved in guides in the frame e by screws c, worm-wheels, and worms on a cross-shaft c<3> to tighten the saw, but, to cant the pulley, the worm which i: clamped by the handle c<7> to the hand-wheel c' is freed, so that only one slide is moved. The screws c pass through the feathered worm-wheels and abut against two levers fixed on a shaft d', one of the levers being connected by a link d<2> to the short arm d<3> of a weighted lever. The tension of the saw depends on the angle between the arm d<3> and the link d<2>, and may be indicated by a pointer affixed to the shaft d'. A shaft g carrying the pinions a<2> for traversing the carriage a carries a wheel g<1>, gearing with a pinion on the same shaft as a friction pulley mounted in a frame l pivoted i line with the shaft g. The frame l is moved by a lever l<2> to bring the friction pulley into contact with either of the friction pulleys m, n, which are rotated at different speeds and in opposite directions by gearing m<1>, n<1> and a belt pulley n<2>. A shaft for operating the lifting-screws e' of the frame e is similarly connected with the pulleys m, n and is controlled by a lever k<2>.

Inventor: LAKHOVSKY GEORGE GIRSCH
Filed: 1903-04-03
Granted: 1904-03-31
Abstract: 7775. Lakhovsky, G. G. April 3. Rails, securing to sleepers; chairs.-Relates to means for preventing the working loose or play of spikes or bolts and the like in their holes and specially those employed in connection with the wooden sleepers of railway rails. The apparatus consists of a sleeve, in the form of a split tube or two or more shells, which surrounds the lower part of the bolt and is provided with serrations or tapered notches on its exterior surface. A conical nut, into which is screwed the bolt, is provided with wedge-shaped lugs, which fit between the parts of the sleeve, the nut pressing these parts outwards when the bolt is screwed up. Fig. 9 shows 296 *a view of the tool used to fix the parts in position, which consists of a tube c having two bayonet slots c', which are traversed by two projections d upon the rod d'. A suitable hole is first bored in the sleeper and the parts a of the sleeve and the nut b placed in position on the rod d<1>, the whole being then driven into the sleeper, as shown in Fig. 11. The tube c is then turned so that the projections d rest in the long slot c<1>, and the shell a only is then driven further into the position shown in Fig. 12. The tube c and rod d' are then withdrawn and the spike or bolt e is passed through the chair to be secured, and screwed into position, as shown in Fig. 14. The nut b is thus locked in position and all the parts are rigidly fixed. Figs. 22, 23, and 25 show a modification for securing rails in position without the use of chairs. In this case, the two portions of the shell are made unequal in length, so that the head of the bolt or spike will rest upon metal at all sides. The first part of the operation of driving the nut and shell into the sleeper is, in this case, done by the rod g and cap h, the shell being then completely driven in by the hollow piece i. These tools are then withdrawn and the bolt e screwed into position, as shown in Fig. 25.
