Title: Improvements in and relating to Pressure Gauges and the like for Pneumatic Tires and other Compressed Gas Containers.
Inventor: POLO JOSEPH BORGIA
IPC: B60C23/04
Filed: 1913-05-19
Granted: 1914-05-19
Abstract: 11,595. Polo, J. B. May 19. Safety-valves; tyre-inflating valves.-An adjustable pressure gauge for pneumatic tyres &c. is adapted for attachment to the stem of the tyre valve and indicates whether the pressure obtaining within the tyre is outside the prescribed limits by actuating a single valve and permitting an escape of air ; in the case of an excess of pressure, the escape continues until the prescribed maximum pressure is reached. The lower extremity of the device 6, Fig. 1, is screwed to the upper portion 4 of the tyre valve 1 and is protected by the sleeve 2 of the valve. A member 8, provided with an aperture communicating both with the chamber above and with a passage 29 leading to an attached cylinder 28, is adapted to engage the upper part of the stem of the tyre valve 3 and unseat the valve. When the valve is displaced, the pressure beneath an elastic diaphragm 10 moves the plunger 15 first against a spring 17, and then against an additional spring 27. Should the pressure be in excess of the maximum allowed, a projection 36 on the plunger rocks a bent lever 39, which depresses a slide 41 and opens a valve 30, thereby allowing air from the tyre to escape from the opening 32, in an upper cylinder 31, by way of the passage 29 and cylinder 28. Should a deficiency of pressure obtain within the tyre, the projection 36 engages directly the horizontal arm of the slide 41 and open the valve 30 as before. The springs 17, 27 can be adjusted by means of the threaded members 18, 25; the spring 27 may, by adjustment of the member 25, be arranged so as to prevent an escape of air from the tyre in the case of an excess of pressure. The form of the device shown in Fig. 1<a> is similar to that described above; in this case, however, the valve 34<a> allowing the escape of air from the tyre is mounted within a recess in the body of the device 11<a>, air passing thence through a passage (not shown) to a third recess in the device 11<a> and thence into the air.

Granted: 1914-02-19
Abstract: 13,434. Polap, B. June 10. Dams and stoppings.- When fire breaks out in a mine, the galleries are shut off by a collapsible and portable device comprising uprights covered with sail-cloth, the sailcloth having lateral and upward extensions adapted to be pressed against the sides and roof of the gallery by springs attached to the edges of the sail-cloth and mounted at the upper ends of each upright and longitudinally of the side uprights. The uprights are extensible and may consist of two telescoping tubes or two relatively movable parts 1, 4. The sail - cloth is secured to the bars 1 and to the upper ends of the bars 4 and has extensions adapted to be pressed against the roof and sides by springs 6, 7, Fig. 3. When the device is collapsed, the springs 6 of each upright are held by a pin 10 on a bar 8 pressed upwards by a spring 9, the springs being released when the bar 8 touches the roof as the device is set up. The side uprights, shown in Fig. 10, comprise a channelled lower part 1, over the web of which two bars 12 forming the upper part 4 are movable and may be held by a pawl 20 engaging teeth on the part 1. When collapsed, the part 4 holds downward a spring- pressed bar having pins 14 engaging the springs 7 on the lower part 1, while the springs 7 on the upper part 4 are engaged by a bent portion 19 of one flange of the part 1 ; on raising the part 4, both sets of springs 7 are freed. The part 1 has a projection 22 forming a foot step, and the part 4 has a similar projection 23 for manipulation by hand. When in use, the springs 6 help to hold the device resiliently.

Granted: 1913-12-18
Abstract: 17,116. Bouillon, C. July 25. Moulding-machines with a vertically-movable table carrying the pattern have means for vibrating the pattern in the plane of the pattern plate in directions at right-angles. A cam-plate 34 provided with adjustable projections 36 and corresponding flats is oscillated by a hand-lever 44. Four rolls 43 carried by a plate 18 secured to the pattern plate are engaged successively by their corresponding projections. When the handle 44 is in position to enter the slot 49 to permit withdrawal of the pattern by the lever 23 the four rolls engage a concentric portion of the cam plate and locate the pattern in a central position. A slot in the head 20 carries a cross-piece 40, 41 engaging a slot at right-angles in the plate 18 forming, as it were, an Oldham coupling. A plate 11 which receives the flasks forms a limit stop for the upward movement of the head 20 and has a cover flange 51 for preventing the clearance round the plate 18 from being choked with sand.

Title: Process for Recovering Zinc from Zinciferous Materials.
Inventor: TIMM FRIEDRICH CARL WILHELM
Filed: 1913-10-06
Granted: 1915-06-17
Abstract: 22,519. Timm, F. C. W. Oct. 8, 1912, [Convention date]. Distilling zinc.-In the extraction of zinc by blowing a charge of ore and fuel on a grate or like support, the charge is removed from the grate after a short period of blowing and is re-deposited on the same or another grate for continuation of the blowing, and so on. A converter-like vessel A for use in the process is mounted on hollow trunnions, through one of which B, blast is supplied to the grate F, the zinc vapours &c. escaping through the other trunnion B2. Red-hot coke is first placed on the grate and is then covered with a mass of preferably preheated charge, whereupon the blast is started. After a short time, the blastsupply is stopped, and the converter is rotated or oscillated before the blast-supply is re-started. Continuous working may be effected by using a long drum-shaped converter or rotary furnace, having a grate parallel to the axis. In a modification, several grates may be arranged in a rotating or oscillating furnace and supplied with blast at the moment they are sufficiently covered with the charge, the blast-supply being cut off as soon as the grates are no longer covered.

Title: Improvements in Electrical Signalling Apparatus.
Inventor: DEARLE GEORGE
IPC: G08B5/38
Filed: 1913-10-16
Granted: 1914-06-18
Abstract: 23,478. Dearle, G. Oct. 16. Order apparatus.- When the transmitting- handle is moved, the signals are all connected in parallel with the supply, the corresponding signals at the two stations being in parallel. This causes the signal elements, in the case of lamps being used, to glow dimly, but when a signal is given by short-circuiting the corresponding lamp at the transmitting-station, the lamp at the receiving-station burns brightly. In the form shown in the drawing filed with the Provisional Specification, the batteries 0 are normally in open circuit, but when a handle h at station x is moved, the battery is connected across the lines b<1>, b<2>, and the lamps d<1>, d<2>, d<3>, d<4> burn dimly. When the knob k is depressed and closes a contact as m<1>, the lamp d<1> is short-circuited, the lamp d<3> burns brightly, and an audible alarm c<3> is actuated. Any number of stations and signals may be provided, and the signals may be arranged so that a group of them burns dimly before the desired signal is selected. The lamps may be replaced by solenoid flags. Fig. 4 shows a construction of transmitter handle. When the handle v is rotated to bring the pointer y opposite an indication on the dial r, the spring 6 is opposite a contact of the series 1, 2, 3. The studs 8 are pressed into notches in a disk 9 by the spring 10 to obtain accurate adjustment. The battery circuit is bridged across the rings i, j by the contact p, and when the knob l is depressed, the short-circuit is completed through the spring 6 and contact 1.

Title: Gyrostatically Controlled Wheeled Vehicles.
Inventor: GRAY JAMES GORDON
IPC: B62D61/02
Filed: 1913-12-24
Granted: 1914-03-26
Abstract: 29,678. Gray, J. G. Dec. 24. Gyroscopic apparatus.-Gyroscopic means for stabilizing and steering a laterally unstable wheeled vehicle, or for steering a laterally stable wheeled vehicle, comprise a gyroscope G mounted on vertical bearings b<2>, b<2>, Fig. 1, carried by the vehicle in the case of the unstable vehicle, or by a frame F, Fig. 3, mounted on horizontal bearings b<3>, b<3> in the case of the stable vehicle, and a spring g connecting a crank-arm on the gyroscope to a fixed point on the vehicle, so that the gyroscope possesses two instabilities without rotation of its flywheel, and is thus completely stable when the fly-wheel is rotating. The gyroscope in its precessional movements controls the steering-mechanism in such a manner that forward motion of the vehicle tends to keep the spring g at right-angles to the gyroscopic axis; this result is obtained by the use of two drums p<1>, p<2>, which are driven in opposite directions at the same speed by means of a motor, and around which cords are led, each connected at one end to the frame of the gyroscope and at the other end to a bar b<4> connected up to the steering-wheel w<2> of the vehicle. The steering power is thus derived from the motor and not directly from the gyroscope. The car may be steered through the gyroscope by Hertzian waves or trailing wires.

Title: Improvements in Vacuum Cleaning or Dust Collecting Devices of the Portable Type.
Inventor: MATHIE FREDERICK JAMES BROWN
IPC: A47L5/04
Filed: 1914-05-12
Granted: 1915-05-12
Abstract: 11,668. Mathie, F. J. B., and Farrow, R. May 12. Vucuum cleaning-apparatus; bellows.-Relates particularly to that class supported by two or more wheels and adapted to be moved backwards and forwards on the carpet or similar surface, the bellows of the apparatus being operated from the wheels. For cleaning upholstery, a hand nozzle is coupled to the suction pipe, the floor nozzle being held out of action. The light supporting - frame a, mounted on the wheels, carries the handle 4 and bail 5. The wheels carry crank - pins 6, Fig. 1, to which are coupled links 7 so that motion is transmitted to a cross-bar working in slots 9. The bellows p are secured to the crossbar and are opened and closed as the cross-bar reciprocates. The forward end carries the dustremoving chamber d, which may have a hemispherical lower end and a removable cover c. The dust chamber contains a removable canvas bag to receive the dust from the suction nozzle g, which may be supported on the arm h pivoted in such a way that the nozzle adapts itself to inequality in the carpet, the flexible hose j also assisting in this movement. To adjust the nozzle laterally, it is made in two parts, pivoted together and adjustable by means of a bolt and nut and slot connexion. To secure the leather of each of the bellows to the corresponding end disk or plate r, the disk is beaded over at its edge to allow the leather q to curl over and to be secured by semicircular hollow clamps s, the ends of the enveloping clamps being secured by bolts which pass through tightening-up lugs. The outlet valve passage u of each bellows is larger in area than the inlet t. The adjacent ends of the bellows are connected by a bolt and boss connexion v. The front air chamber w communicates with the dust chamber d through apertures x which are protected by an inner screen y. The front and rear air chambers are connected by the air passage 2, and each communicates with the inlet air valves t. The bellows are enclosed by the casing 3. Fig. 4 shows a modification in which the disks of the bellows are made of wood, with grooved edges in which the leather is secured by wire rings 19 with couplings 20. The connecting air passage 2 in this case supports the disks through a sliding sleeve 21, a distance-piece 22 preserving the space between the bellows. Motion is communicated to the bellows from the rear wheels b through crankpins 6, links 7, studs 24, bowls 25, and links 26. Front wheels are dispensed with, so that substantially the whole weight of the apparatus tends to keep the nozzle g on the floor. The dust chamber d is arranged horizontally, the cover c being at the front end and secured by clips 13. The cover is formed with the passage 14 preferably elongated to admit of lateral shifting of the nozzle.

Title: Improvements in or relating to a Method of and Means for Producing Coloured Pictures, for instance Copies from Screen-plates.
Inventor: CHRISTENSEN JENS HERMAN
IPC: G03C7/04
Filed: 1914-05-29
Granted: 1915-01-07
Abstract: 13,260. Christensen, J. H. May 29. [Addition to 25,419/13.] Colour photography.-Relates to processes for reproducing from autochrome and like screen photographs, or for producing colour photographs from separate component negatives by utilizing films of the kind described in the parent Specification. These films are made with silver bromide or like emulsions, which are characterized in that the permeability of the exposed parts is increased by development. The processes are adaptable for kinematograph colour films when reproducing a multicolour screen transparency. Three pieces of paper are coloured with dyes complementary to the colours of the screen plate to be reproduced, and are provided with films of the above-mentioned kind. These papers are brought, one at a time, into contact with a single plate or film containing a solution of the developer and illuminated through the screen plate by light which in each case is complementary to the colour of the coloured paper. The screen plate and the developer plate are maintained in the same relative position, and during each exposure, the developer acts upon the sensitive film and dye diffuses into the plate containing the developer in proportion to the intensity of the transmitted light. A colour picture is thus obtained in the film containing the developer, which can he mounted on paper or used as a diapositive. The process is the same whether for contact printing or enlargements. In adapting the process for producing copies from separate colour negatives, correct registering of the individual negatives is necessary; such registration is, however, effected before the following coloured paper is placed on the developed picture film. The developer plate can be formed by coating a glass plate or film with gelatine, and superimposing a film of less porous nature, such as hardened gelatine, viscose, or a porous nitrocellulose film, produced by pouring on a glass plate of 100 sq. cm. area about 10 ccs. of a 4 per cent collodion solution, to which is added 3 per cent of citric acid. The plate, together with the nitrocellulose film, is immersed in the developer and is placed between the developer and the coloured paper during the exposures. The dyes extracted from the colour films remain in the nitrocellulose film, which can be removed and mounted. The coloured papers are made bv coating a non-absorbent paper base with dyed colloid, or with an ordinary gelatine-silverbromide film dyed, and sensitizing this with a panchromatic film of the kind stated. In the case of the yellow paper which is acted on by blue light, an ordinary emulsion may be used.

Patent GB-191502532-A (GB)
Title: Improvements in and relating to Controllers for Electric Lifts.
IPC: B66B1/08
Filed: 1915-02-17
Abstract: 2532. Major, C. G., and Smith, Major, & Stevens. Feb. 17. Electric push-button systems; electric plant. -In an electric lift controller with a single reversing switch which remains closed at the moment of stopping, two switches on the reverser bar are connected in the actuating circuit of the circuit-breaker, and two other switches are arranged for cutting out the reverser solenoids. The reversing switch 17 for the motor 20 is operated by up and down solenoids 7, 8, and one of the switches 18, 19 is closed at the same time as the reverser. The call buttons 1, 2, 3, 4 are connected in parallel with the cage buttons, and in series with the solenoids 1<b>, 2<b>, 3<b>, 4<b>. The momentary depression of any button energizes the corresponding solenoid and its core rises to complete a maintaining circuit through the up or down bus - bar 5, 6, the particular bar employed being selected by an automatic switch dependent on the movement of the cage, as described in Specification 9195/08. This maintaining circuit includes one of the reverser coils 7, 8 according as the up or down bus-bar is energized. The closure of one.of the switches 18, 19 energizes the coil 11 which closes the circuitbreaker 12, 12<a>, and opens the switch 22 so that no other button is effective until the travel of the lift is completed and the circuit-breaker is opened. The switch 22 also opens the circuit of the reverser coils 7, 8. As the motor starts it operates a rheostat 13 through a friction clutch to cut out resistance from the armature circuit. The rheostat. in moving, opens switch 23 and this switch remains open until all resistance is in circuit again. The solenoids 7, 8 do not exert equal forces tending to move the bar 10, so that if both solenoids are energized the reversing switch will still be operated. Under ordinary circumstances the resistance 14 only permits sufficient current to pass to energize one of the solenoids 1<b>, 2<b>, &c., so that if two buttons are depressed, none is energized. The friction clutch for driving the rheostat is shown in Fig. 2. An arbor 24 fixed to the controller frame 25 carries a chain wheel 26, driven by the motor, and a terminal flange 27, the bosses of which mesh together. A chain drum 28 and two friction disks 29, 30 revolve on these bosses. A sleeve 31 is prevented from revolving by a pin but it carries a ring 32 which is free to revolve. All the parts are free to move axially until the solenoid 11 is energized and the circuit-breaker closes. The arm 33 then applies pressure to the clutch so that the parts are gripped between the flange 27 and the frame 25. The rheostat is operated from the drum 28 which slips after all the resistanoe is cut out. An arm on the ring 32 is connected to the lever 9 of the reversing switch, and as the ring is held between non- revolving surfaces the reversing switch is locked on until the motor stops and the circuit-breaker opens. A three - position switch may be employed instead of push buttons to control the lift.
