Title: Improvements in, and relating to, Photographic Cameras
Filed: 1902-11-26
Granted: 1903-11-26
Abstract: 26,068. Lake, H. H., [Soc. L. Gaumont & Cie.]. Nov. 26. Cameras; darkslides; shuttters.-A folding camera has the front and back connected by togglelevers to set the lens at the focussing distance, and has a flexible casing attached at any point which can be folded round the camera, when closed, and secured by buttons &c. The bellows of the camera are secured to the front and back by metal frames placed inside the folded ends of the bellows and fixed by screws. The front of the camera has a sliding plate b which, in its closed position, normally covers the lens opening. The plate carries a view-finder c and a detent k which engages with a stop h on the shutter i to set the shutter as the view-finder is drawn out, the detent being tripped from the stop h so as to leave the shutter free to be released by the press-button. The shutter is operated by a spring and is connected with a speed-regulating piston r by a rod s. The rear end of the cylinder containing the piston is closed by a plug having a central bore leading to a tapering groove on the surface, which abuts against a perforation in the cylinder so that the air escape can be regulated by turning the plug. The shutter is released for instantaneous exposure by the push p, which, acting on the lever n through the lever q, releases the stop-pin m. In making a time exposure, the piece t carrying the lever q is slid so as to act on a tripping-lever carrying a turned-over portion u so that, when the pin m. is released from the lever n, the lever x is depressed to catch the pin y. On releasing the pressure from the push p, the levers return to their normal position and the shutter is closed. The view-finder c is provided with an articulated glass, which can be folded flat so as to slide into the closed position, but can rest against a stop when opened to form a reflecting-surface for viewing from above. The glass can also fall flat on to the camera, when the view can be watched by observing through a perforated leather disc mounted in a pivoted arm on the back portion ; a reflecting view-finder may also be mounted on this arm in place of the one on the front. The dark slides have distinctive coloured or numbered tabs for indicating the plates used. A pivoted stirrup frame is mounted on the back of the camera, which can be swung over the opening after the shutter of the dark slide has been removed, the shutter being placed in behind the stirrup frame to hold the frame in its forward position. The camera may have the shutter part made with two openings for stereoscopic work.

Inventor: LINDSAY ROBERT
Filed: 1903-04-08
Granted: 1904-03-24
Abstract: 8126. Lindsay, R. April 8. Clutches.-The shell D of the friction clutch shown in Fig. 1 is keyed to the driving-shaft C. Loosely fitting within the shell is the expanding ring F of elastic metal, which is cut across at one point and doubly coned on the inside. The coned surfaces engage the cones G, H. The nave of the cone G is free to slide on the feather Ion the driven shaft E. At the outer end of the nave is the friction band J with a trunnion K on each side. The nave of the cone H slides on the feather L on the nave of the inner cone, and has a similar band J with trunnions, near the web of the cone. The stationary sleeve M rests on the nave of the inner cone, and has on each side a trunnion N, on which swings a lever P, connected by links 0 to the trunnions K on the bands J. The levers P are connected by the stud R, which is engaged by the lever S working on the fulcrum T. On moving the lever S to draw the cones G, H together, the ring F is caused to expand and to grip the shell D. The lengths of the links 0 are adjusted by right and left hand screws and nuts. Brackets, studs, or projections W may be attached to the expanding ring or to the shell to retain the ring in the correct position, as shown in Figs. 10, 11, and 15. The expanding ring may be cut in two or more places, the parts being connected to the cones by T-sliding keys &c. The expanding ring may be dispensed with, and the cones made to engage with conical surfaces formed on the shell. Fig. 3 shows a modification, in which the parts G, H have projections engaging V-shaped grooves formed on the ring I<1> on the shell. As shown in Fig. 4, the levers S operating the cones G, H are actuated by the right and left hand screw U and the handwheel V. Fig. 6 shows a modification, in which the cones are operated by the right and left hand threaded sleeves X, Y, which are engaged by the worm-wheel B', actuated by a worm on the shaft E<1>. The sleeves X, Y are prevented from rotating by levers G<1> and studs F<1>. Means for locking the cones together are shown in Fig. 16. The bands J', J', operated by levers S, engage with stop rings T<1>, T<2>, T<3>, T' on the naves R<1>, S<1> of the cones. Keys U<1>, placed on flat springs in beds in the nave S', bear against the face of the nave R<1> in the position shown in the Figure. They are depressed in the beds by the band J' to enable the naves to slide one on the other.

Title: Improvements in Devices for Operating Doors, or Traps, and the like, more especially Intended for Effecting the Discharge of the Contents of Wagons and other Receptacles.
Inventor: JOHNSON JAMES YATE
Filed: 1904-06-13
Granted: 1905-04-13
Abstract: 13,359. Johnson, J. Y., [Soc. Anon. des Forges de Douai]. June 13. Doors, wagon.-Doors, traps, and the like, especially the doors of hopper wagons, are operated by a swinging link 8 pivoted at 9 and having at its lower end a roller running on a curved rail 11 fixed to the door. The door is pivoted at one end on trunnions, each of which can slide in an elongated slot 4. To close the door, a shaft 16 is rotated to wind up a chain 17 which lifts the door. At the same time, a pinion on the shaft actuates a rack 15 which puehes on the link 8 and causes the roller on the end of the link to move along the rail 11. When the door is fully raised, the roller will have moved up to the stop 12, and its further motion will carry the door towards the right, the trunnions sliding in the elongated eyes 4 to allow this, and the lower right-hand edge of the door will thus be moved over the support 5. To open the door, the shaft is turned in the reverse direction, so that the roller on the link 8 is moved to the left into the position shown, when it comes against another stop and pulls the door away from the support 5 until it can fall open. The chain 17 is always kept taut by a spring connecting the pulley on which it is wound to the shaft 16.

Title: Improvements in or relating to Apparatus for Automatically Extinguishing and Re-lighting Gas Burners.
Inventor: OLSEN OLE MIKAEL JOHAN
Filed: 1904-09-19
Granted: 1905-07-13
Abstract: 20,191. Olsen, O. M. J., and Gates, W. Sept. 19. Lighting and extinguishing gas.-Relates to an arrangement for automatically extinguishing and re-lighting gas burners, by the movement of the bell of a gas regulator operated by a predetermined maximum gas pressure. The bell C, Fig. 1, of a gas regulator works in an annular chamber B containing mercury, glycerine, or other fluid. The foundation plate F closing the central chamber A carries a central gas pipe G and two subsidiary pipes J, L, which lead by exterior pipes K, M to chambers G<1>, I<1> communicating with the pilot light and burner respectively. The pipes J, L terminate in mercury chambers N, 0, and are covered by bells P, Q suspended from a balance lever R pivoted on a standard S of the foundation plate. The bell C is provided with a central stem D which is constrained to move vertically by two parallel links U, V connected to a standard T. A shorter standard carries a lever X, having a weighted arm D' to counteract the pressure of the buoyant medium, and joined by the connection Y to the bar V and crosshead J<1>, by which it is operated. An independent bar Z, with a cam-shaped end, is pivoted to the standard T above the bar V. The bar Z is enclosed by the connection Y, so that, during the upward movement of the stem D, it is caused to rise and engage with a looped lever B' suspended from the pin which supports the balance lever R. The latter lever is operated by the lever Z, to which it is attached by a rod C<1>. Each lever is made double so as to operate on either side of the vessels N, O. When the bell is in its lowest position, as shown in Fig. 1, the gas enters the chamber A through the pipe G, and passes through the pipe K to the pilot light. When the bell C is raised by increased pressure to its highest position, the lever R is tilted in the opposite direction, the bell Q being raised and the bell P lowered, so that the burner is lighted and the pilot light extinguished. As the central stem rises, the crosshead J<1> pushes the pendulum E' away from the stop F' of the looped lever B', which will allow the lever Z to engage the lever B'. When the pressure is reduced, the dome C falls, and the pendulum E<1> swings on the opposite side of the centre, so that, when the pressure is again increased and the dome rises, the crosshead J<1> forces the stop F<1> of the pendulum against the looped lever B', thus releasing the lever Z, which then falls back into the position shown, the burner being extinguished and the pilot re-lighted. The release of the lever Z can only be effected by the maximum increase of pressure, and is not effected by varying pressures between the maximum and minimum.

Abstract: 22,127. Merck, W., Merck, L., Merck, E. A., and Merck, C. E., [trading as Merck, E.]. Jan. 28, [date applied for under Patents Act, A.D. 1901]. 4-Imino-2 : 6-dioxypyrimidines are produced by condensation of acidyl-ureas or alkylated-acidylureas with a cyanacetic ester in the presence of alkali metals or their alcoholates. In an example, acetyl-urea is boiled with a mixture of absolute alcohol and cyanacetic ester containing sodium. The alcohol is distilled off, water is added, and 4 - imino - 2 : 6 - dioxyprimidine is precipitated by adding mineral acids. 3-Methyl-4-immo-2 : 6- dioxypyrimidine is prepared similarly from acetylmethylurea. In another example, cyanacetic ester is added to a cold mixture of xylene, sodium, and benzoylethylurea. Towards the end of the reaction, the mixture is warmed, water or dilute alcohol is added, the xylene is removed, and 3-ethyl-4-imino-2 :6-dioxypyrimidine is precipitated by adding acetic acid.

Title: Improvements in or relating to the Burning of Liquid Hydrocarbons, Gas and the like.
Inventor: BOSWELL CECIL ROBERT
Filed: 1904-10-24
Granted: 1905-09-07
Abstract: 22,853. Boswell, C. R. Oct. 24. Vapour &c. burners.-Air is supplied to hydrocarbon, gas, or like burners by mechanical means such as a fan, which is driven by a turbine or other motor actuated by the inflammable vapour or gas consumed in the burner. Liquid hydrocarbon is supplied from a tank to the vaporizing- coil A, Figs. 1 and 2, and flows in the form of vapour through the tube D and valve E to a turbine F or other motor, which it causes to rotate, and afterwards passes from the exhaust passage of the turbine through the tube H to the burner C. The turbine is preferably mounted upon the same shaft J as a fan L which supplies air through the tube N to the burner, where it mixes with the vapour. A drain valve Q is provided to take away condensed vapour from the turbine, the vapour being led through the tube R to the chamber S, which also collects condensed vapour from the tube H. The condensed vapour is returned through the tube U to the storage tank. To start the burner, spirit is placed in an annular trough V at the top of the burner and ignited, the flame being directed by an adjustable spreader W on to the vaporizing-coil. If desired, the vapour and air from the turbine and fan may be led to more than one burner, and, further, the condensed vapour in the turbine may be led to an anxiliary vaporizer. According to the Provisional Specification, the vapour from the coil may be caused to impinge against the vanes of a fan which may also, by its rotation, draw in air and mix it with the vapour.

Title: Improvements in Acetylene Gas Generators.
Inventor: BECK CHARLES WILLIAM
Filed: 1905-05-15
Granted: 1906-02-22
Abstract: 10,185. Beck, C. W. May 15. Actuating valves.- The feed valve of an acetylene generator for automatically supplying carbide to the water is normally actuated by a diaphragm but is provided with means for locking the valve closed when the lamp is upset. The diaphragm 22 which has a flange 23 clamped in a channel 16 by an annular plate 24 is coupled to a valve spindle 26 which is reduced in diameter to form a shoulder at 30, the reduced part being threaded as at 31, Fig. 4. The valve 33 engages a flexible seat 10 secured in position by a screwed ring 11 and is mounted on the lower end of a sleeve 32, being secured in position by screwing on to the end of the valve spindle. To the upper end of the sleeve is secured a small collar 35, and loosely mounted on the valve-rod and enclosing this collar is an upper stop 36 formed of two telescopic shells 37, 38 fitted snugly together, the exterior diameter of the stop being slightly larger than the opening in the valve ring. A packing-ring below the collar 35 forms a gas and water tight joint with the valve stop 36. A flexible tube 39, Fig. 1, preferably of rubber, terminates the tube 21, and it has a sharp edge which is in rubbing contact with the valve stop 36, the friction being sufficient to hold the member 36 in its upper or lower position when moved by the valve mechanism. The lower stop 33 is formed with a reduced portion 33<a> which normally works into the valve ring and regulates the feed of carbide, but under abnormal conditions, such as the overturning of the lamp, the larger part 33<b> is forced into the valve ring. The diaphragm is loaded by a spring 56 acting through trip levers 46, 51, which can be set by means of a screw 50 and pin 54. The levers are normally prevented from tripping by a ball 42 engaging a stop 57. Should the lamp upset, the ball will be displaced thus allowing the diaphragm and levers to rise abnormally, which trips the levers and causes the spring to hold the valve closed. In a modification of the apparatus, shown in Fig. 12, the pin 54 is omitted, the valve being re-set after abnormal displacement by pulling it down.

Granted: 1906-03-08
Abstract: 14,555. Fournier, G. H. July 14. Roundabouts; amusements for fairs and the like.-The apparatus consists of elevators 1, Fig. 1, which are raised and lowered by means of cables 2 which pass around a motordrum 3. The elevators are constructed of a base 1<1>, Fig. 2, which contains mechanism for rotating the car 1<11>, which is supported upon ball bearings 9 on the base 1, and is mounted by means of a hollow shaft 7<1> on a shaft 7. The elevator is provided with guide-rollers 5, 13, which move over rails 6 of a vertical frame, the revolution of the car 1<11> being guided by depending arms 14 provided with rollers 15 which revolve in a guide 20. The car is rotated, as it ascends and descends, by means of wheels 17, which engage a crown-wheel 16 on the car and are connected by gearing to an electric motor 18. This motor is connected to conductors 21, 21<1>, Fig. 4, placed along the rails 6, by means of sliding contacts 22, 22<1>, connected to the motor and to insulated contacts 24, 24<1> on the shaft 2. The contacts 24 are connected by means of contacts on the shaft 7<1> to a commutator 26, and rheostat 27, by means of which the current can be regulated. As shown in Fig. 1, two cars are driven by one drum 3, but the cars may be independently actuated. The drum 3 can be carried by the base 1<1>, in which case the cable 2 is attached to a fixed hook at the top of the supporting frame, and the cable passes through the shaft 7, which is made tubular. The motor of the drum 3 may be controlled similarly to the motor 18, so that both the vertical and revoluble motions of the car may be varied at will. The rollers 15 may be dispensed with, and the shaft 7<1> revolve on two sets of ball bearings. The motor 18 may drive this shaft directly by means of bevel-gearing. When a single car is used, its cord 2 may be connected to a counterweight, the weight of which can be adjusted by means of sand. The cable, in this case, passes over a motor drum provided with a hand-brake. The car and weight are connected to separate safety cables, which pass over drums provided with brakes. The current may be supplied by means of the cables 2, or by conductors coiled beside the cables 2.
