Title: Improvements in and relating to the Control of Electric Motors.
Filed: 1907-10-02
Granted: 1908-04-16
Abstract: 21,811. Benrather Maschinenfabrik Akt.-Ges. Oct. 3, 1906, [date applied for under Patents Act, 1901]. Switches; motor control systems.-Motors working on irregular loads, such as those operating lifts, are prevented from attaining an excessive speed by means of a high resistance electro-magnetic switch arranged in parallel with a regulating resistance, the switch operating at a predetermined speed to cut out the regulating resistance and insert its own resistance in the armature circuit, and at the same time causing a mechanical brake to act. The coil k, possessing itself, or in combination with an inserted resistance, a high ohmic resistance, is connected in parallel with the regulating resistance r<1> ... r<4> through the contact i. When the back electromotive force of the armature a reaches a predetermined value, the switch t breaks the circuit of the resistance r<1> ... r<4> at contact i. The circuit of the brake releasing magnets m is also broken at the contacts n. The field f being connected through the resistance p, the current flowing through it is independent of the armature current. A coil l connected across the armature may oppose the coil k.

Title: Improvements in connection with Electric Circuit Breakers.
Inventor: SCOTT WILLIAM HARDING
Filed: 1907-12-21
Granted: 1908-10-01
Abstract: 28,199. Scott, W. H. Dec. 21. Cut-outs ; switches.-An electric circuit-breaker is constructed with one or more U-shaped magnetic pieces embracing a linear conductor, and mounted so as to swing farther over the conductor when sufficient current passes, and thus act to break the circuit. According to the arrangement shown in Fig. 3, two U-shaped soft-iron pieces 1, 2 are mounted on opposite arms of a three-armed lever 3 pivoted at 4. The pieces embrace a straight flat conductor 7, as shown in the detail view, Fig. 5. When excessive current passes, the lever 3 is caused to swing farther in line with the conductor, and then act upon a bell-crank lever 8, which is arranged to break the circuit by some means (not shown), for example, by releasing holding-on catches. The third arm of the lever 3 is connected to a dash-pot 9, and the movement is also resisted by a spiral spring 10, the tension of which may be altered at will by clamping a sector 13, to which the end is attached, in different positions in a slot 17 by means of a nut 18. The sector 13 is provided with a scale to indicate the current setting against a pointer 19. In a slightly modified form, the spiral spring is replaced by a graduated lever with a sliding weight, and a projection on the lever 3 is made to impinge directly on a switch arm so as to open the circuit. One or more soft-iron pieces 24 are mounted opposite the U-shaped pieces so as to produce a quick final break. The apparatus may be modified by making the respective U-shaped pieces embrace opposite pole conductors.

Granted: 1909-12-23
Abstract: 7421. Boorne, W. H. March 27. Printing-surfaces.-In making a half-tone rubber stamp from a photograph, the following method is adopted. A negative is taken through a ruled screen of suitable grain, and from this a positive is printed on a paper having a film of gelatine impregnated with a chromic salt, and, if desired, a substratum of collodion or albumen. A pigment is preferably added to the gelatine to prevent halation. After exposure, the film is transferred to a glass plate coated with a layer of insoluble gelatine, and the image is developed on this by washing the unexposed portions away in warm water. The picture, which stands out in strong relief, is treated with formaldehyde or chrome alum to harden it, and may be coated with wax. A cast is now taken from this positive in fine plaster of paris or other suitable material, and on this cast a sheet of rubber coated with french chalk or other suitable substance is laid, and subjected to heat and pressure until the rubber is suitably moulded. According to the Provisional Specification, alcohol, or bichromate of potash or ammonia, in weak solution, may be employed as a hardening-medium.

Granted: 1910-05-26
Abstract: 12,669. Cartwright, E. O. May 28. Platen presses ; inking - apparatus; throw. out arrangements.-A platen press is constructed so as to print sheets or webs accurately and quickly, the forme-bed being combined with an ink-distributing roll and being reciprocated by sliding blocks in a plane perpendicular to the fixed platen so that its face remains parallel with the platen in every position. As shown, the impression surface is mounted on a platen 45 rigidly secured to a shaft 47, which is normally held stationary by bolts 49 in the frame, which engage recesses 51 in the shaft 47. By removing these pins, the platen may be turned up for making ready. The type bed 16 is integral with a roll 17, which receives ink from ductor rolls 34, and the bed is inked by spring-pressed rollers 25, which are rotated around the roll 17 and bed 16 by a sector 20 in which they are mounted. The bed 16 and the roll 17 are fixed to sliding blocks 5, which are reciprocated in guides by pins 7, Fig. 2, on gear-wheels 8 which engage slots 6 in the blocks, and the sector 20 is rotated around the parts 16, 17 as they reciprocate by means of a sprocket chain 22 which is passed around a wheel 23 carried eccentrically by a shaft 12 in such a manner as to keep the chain taut in all positions. The ductor rolls 34 are mounted in pivoted arms 35 pressed inwards by springs 36 on jointed rods 37 fitted with stops 40. As the roll 17 descends, it forces the ductors into contact with rolls 33 supplied by fountains 32, which are adjustable in position by means of bolts ; and, as the roll 17 ascends, the rolls 34 rotate and ink the roll 17. The rolls 34 are fitted with riders 41. When two fountains are used, the roll 17 may be divided into two parts, each of which receive a different-coloured ink. When used for printing on sheets, the sheets are fed by means of any automatic sheet-feeding mechanism, such as grippers carried by rings. The sheets are fed from a pivoted board, which is raised to allow of the passage of the grippers. For throwing off the impression, when desired, the platen shaft is provided with trunnions 52 mounted in bearings in boxes 53, Figs. 2 and 4, which are mounted so that they can only slide vertically in square apertures 54 in the frame. The trunnions 52 are also eccentrically mounted in sleeves 58 mounted in boxes 57, arranged adjacent to the boxes 53 but capable of horizontal movements in the apertures 54. On rotating the sleeves 58 by means of a handle 63, rock-shaft 62, links 60, and arms 61, 59, the platen is raised but maintains its horizontal position in doing so. The shaft 47 remains locked to the bolts during the throw-off. The machine may be fitted with an automatic roll-feed instead of a sheet-feed.

Title: Improvements in Steam Superheaters.
Inventor: JACOBS HENRY WILLIAM
IPC: F22G7/10
Filed: 1909-10-25
Granted: 1910-09-15
Abstract: 24,467. Jacobs, H. W. Oct. 24, 1908, [Convention date]. Superheating - chambers heated by furnace gases.-Steam is superheated in two separate chambers 5,12, traversed by smoke-tubes and arranged in the smoke-box of a locomotive or like boiler, the tubes 9, 13 of the chambers being in alinement with each other and with the smoketubes 22 of the boiler. The uptake 19 and the blastpipe 20 are arranged between the chambers. The furnace gases pass in succession through the smoke-tubes 13, 9 and then return through a central passage 18 in the chamber 5 and pass into the uptake. The seams of the chambers are welded together so as to make each an integral structure. In the superheater shown, the steam passes first into the front chamber 5 and then through a pipe 3 to the back chamber 12, from which it is taken to the cylinders through a pipe 16. In a modification, the steam from the front chamber is led directly into the high-pressure cylinder, the exhaust from which is passed through the back chamber and supplied to the low-pressure cylinders. The front chamber is fitted with partitions compelling the steam to take a spiral course. The back chamber is fitted with transverse partitions, which force the steam to pass backwards and forwards across the chamber.
