Patent GB-190307184-A (GB)
Title: Improvements in and relating to Switching Devices for Intercommunication Telephones.
Inventor: JOSEPH EDWARD LIONEL
Filed: 1903-03-27
Granted: 1903-06-18
Abstract: 7184. Joseph, E. L., and Gardner, G. March 27. Telephone s y stems; telephone calls. -Relates to switch apparatus for intercommunication or directcallsystems. Fig. 2 shows the application of the invention to a telephone wall set. The receiver or combination micro - telephone normally rests in the switch cradle b, which is carried by a bar c pivoted at d. In this position, the bar e connects the spring tongues f, g and closes the call circuit. When the instrument is removed from the cradle, the tongues g and h are connected, and the speaking circuit is closed. To ring up a subscriber, the corresponding push-button k is pressed in, and contact made between the coned head r of the stem l and the bar y, the coned head lifting the pivoted bar s as it passes beneath it. The stems l are in metallic contact with plates o connected to the subscribers' lines, and the bar y is connected to the call battery of the instrument. When the key is released, the head r is detained by the bar s, and connects the speaking and receiving instruments to the selected line. The return of the instrument to the switch cradle lifts the insulated bar z, and the step or notch 6 engages with the bar s and lifts it so as to release the head r of the depressed key stem. The bar s ultimately escapes from the notch and drops again into its active position. The depression of any key releases any others previously depressed, by lifting the bar s, but two or more keys may be depressed together, so that several subscribers may be communicated with at the same time. A table set may be constructed in a similar manner, a bell-crank lever being interposed between the bar z and the vertical plunger which supports the cradle.

Patent GB-190401782-A (GB)
Title: Improved Means for the Automatic Regulation of Stove-fires or the like.
Inventor: BARRY HERBERT ALFRED LUCAS
Filed: 1904-01-23
Granted: 1904-11-03
Abstract: 1782. Barry, H. A. L. Jan. 23. Draught, regulating.-For automatically regulating the draught in stove fires and the like, a pivoted door is provided at the side of the flue and adapted to be opened by the expansion of the flue itself, or by the expansion of a bar of metal arranged within the flue, according to the degree of heat which is generated in the stove. In the case of a vertical flue or stove pipe F, as shown in Fig. 2, an air inlet A is provided with an inclined pivoted door A', the top of which has a projection a. A weighted lever B, pivoted at one end, bears upon the projection a, and also has jointed to it a rod E, the upper end of which is fixed to a strap on the pipe F. As the temperature of the flue gases increases, the pipe F expands, and, by means of the rod E, raises the lever B and thus allows the door A to open and admit air to the flue. A regulating-lever K is interposed between the projection a and the lever B, to set the degree of opening of the door required for normal work. This lever K is pivoted at one end and bears against an adjusting set-screw k<1> at the other. The free end of the regulating-lever may be graduated to indicate the amount of opening for different temperatures. Instead of operating the lever by the expansion of the stove pipe, a metal bar G, Fig. 2, may be arranged across the stove pipe, so that the expansion of its free end may communicate motion to a projection b on the lever B, and thus open the door A' as before. This construction is also applicable to brick flues, in which case a rod within a tube of different expansibility may be used, the differential expansion being caused to operate the lever B and door A. When the apparatus is applied to a horizontal stove pipe, as shown in Fig. 4, the rod G bears directly against the lever B. In another modification, shown in Fig. 5, the weighted lever is dispensed with, and a weight L is attached to the door A', while the expansion of the rod G gives motion to a pivoted lever M which bears against an adjustable screw k<1> on the door.

Title: Improvements in Stoppers for Syphon Bottles or Vessels and in Taps therefor applicable also to Fire Extinguishers.
Inventor: HENRICH JOHN GEORGE
Filed: 1904-01-28
Granted: 1904-09-01
Abstract: 2147. Henrich, J. G. Jan. 28. Stoppers. - Taps and stoppers for siphon bottles, fireextinguishers, &c. are constructed so that one tap may be used for a number of bottles, and the stopper can be readily removed to facilitate cleaning. A porcelain screw stopper a, Fig. 2, is provided with a valve d, having a tubular stem c, to which is screwed a collar e. The collar lies in a recess in the stopper. Normally, the valve d is kept closed against a washer j by a spring g, holes n in the tube c being situated above the washer. The washer is held in position by a screw piece k, to which is attached a siphon tube m. The valve d is opened by depressing the shoulder e by means of a knob r on a tap bead o, Fig. 1, thus bringing the holes n below the washer j, and providing a free passage for the liquid from the siphon tube m to the outlet c ; the recess in the head o which fits over the shoulder is lined. In the case of fireextinguishers, the tap head is pressed down by means of two projecting finger-pieces. In a modification, the piece k which carries the siphon tube may be provided with a flange and held in place by two clamping-rings pressed together by the screw stopper a.

Title: Improvements in Typewriting Machines.
Inventor: FELL JOHN CORRY
Filed: 1904-01-28
Granted: 1904-03-31
Abstract: 2175. Fell, J. C., [Union Typewriter Co.]. Jan. 28. Type-writers.-Relates to a stop mechanism which will afford, when desired, a movement of the carriage beyond the point where it is normally arrested, to allow of writing in the margin. A lever 13, carrying a finger-piece 12 at one end, is pivoted to the front cross-bar 15 of the carriage. At the other end of the lever is a hook 16 having a bevelled face 17 which forms a cam. A spring 18 bears under a flange on the bar 15, and normally depresses the hook end of the lever. A slide 21 having a slot 24 is connected to the carriage bar 15 by beaded screws 22, 23, the former of which screws into the bar while the latter passes through a slot in the bar and is secured in any position in the slot by a nut behind the bar. A margin stop 29 projects from the underside of the slide, while at the end of the slide is a hook 30 which is similar to, and engages with, the hook 16. The slide is pulled to the right by a spring 32 connected at one end to a pin 34 on the slide, and at the other to a pin 33 projecting downwards from the flange 20 of the bar 15. A stop 42 which extends into the path of the margin stop 29 is carried by a block 35 which slides on a transverse bar 3. The block also has a sleeve 36 which partly surrounds the transverse rod 4 upon which the traction roller 5 of the carriage bears. The stop 42 may be held in any position by a pawl 38 on the block 35 which engages with teeth on the rod 4. The pawl is operated by a finger-piece 37. In the ordinary operation of the machine, the hooks 16, 30 are in engagement with one another, so that, when the stop 29 reaches the stop 42, the motion of the carriage is arrested. On depressing the finger-piece 12, however, a further motion of the carriage is permitted until the screw 23 reaches the end of the slot 24. As the carriage is moved back, by the feed motion or otherwise, the spring 32 holds the stop 29 against the stop 42 until the screw 22 reaches the end of the slot 24, by which time the hooks 16, 30 are again in engagement and the carriage and slide move together as usual. The stop 42 is thus never removed from the path of the stop 29.

Title: Improvements in Doors, Gates and like Structures.
Inventor: PITT WILLIAM RAFFORD
Filed: 1904-03-17
Granted: 1904-06-02
Abstract: 6562. Pitt, W. R., and Pitt, R. July 22, A.D. 1903. [date applied for under Patents Act, A.D. 1901]. Gates.-Relates to improvements in the invention described in Specification No. 12,212, A.D. 1903, and consists of means for supporting, guiding, and automatically closing doors, gates, shutters, and the like. The door is supported on a vertical axis passing through its centre as shown in Fig. 1, and is opened as shown in plan in Fig. 2. When the door 4 is opened, in the direction of the arrow, the sleeve 20, to which the door is pivoted, slides on the guide 21, and, by taking against the piece 22, extends the spring 19 ; at the same time. the carriage 5, shown enlarged in Fig. 4, runs in its groove on the antifriction wheels 8, 8a. When released, the door is closed by the combined action of the springs 19, Fig. 2, and 15, Fig. 1. The fixed piece 25 prevents the spring 19 from closing beyond the desired point. This closing-apparatus is situated at 36, 37. Fig. 1, and a similar apparatus may be placed near the bottom of the door so as to operate in the opposite direction. Fig. 6 shows in horizontal section another type of closing-apparatus. The horizontal plate 39, supported on friction rollers 40, 41, extends through a slot in the wall to the plate 36<a>, which is pivoted to the door. A third friction roller 37<a> is attached to the door itself. When the door is opened in one direction, two of the angle-irons 46 attached to the plate 39 take against the piece 44 on the sleeve 42, which thus slides on the guide 47 and extends the spring 49 in the direction of the arrow B ; a similar action occurs when the door is opened in the opposite direction. With this type of apparatus, the friction rollers 37<a>, 40, 41 and the plate 39, 36<a> only are necessary near the bottom of the door. Referring to Fig. 4, the bolt 9 is sufficiently loose to turn in the slot 18, and two pairs of friction rollers 6<a> and 7<a>, Fig. 1, bear against the sides of the groove 13. To keep the door vertical, a horizontal friction roller 30, the axis of which is in the same vertical line as the suspending spindle 9, Fig. 4 works in a slot below the floor.

Title: Improvements relating to Steam Heating Apparatus.
Inventor: PULSFORD FREDERICK CHARLES
Filed: 1905-01-11
Granted: 1905-12-07
Abstract: 556. Pulsford, F. C. Jan. 11. Actuating valves and cocks.-An automatic cutoff valve for use in steam heating-apparatus is controlled by the expansion of a rod placed therein. Fig. 1 shows a part sectional elevation of the device as applied to a radiator. The non- rotatable rod 8, attached to the lift valve 4, passes through the head of the tube 9 which extends through the lower portion of the radiator. At the other end, it is screwed into the cap 12 which can be rotated, and therefore the lift of the valve 4 regulated, by means of the square-headed rod 13. A spring 19 prevents injurious strain on the valve or its seat. The area of the band-controlled valve 3 bears a ratio to that of the cut-off valve 4 which is inversely as the ratio of their respective lifts. In the modification shown in Fig. 2, three concentric expansion tubes 9<a>, 9<b>, 9<c> are employed, the intermediate one of iron and the others of copper, the result being that a greater expansion is obtained for the same range of temperature. In this case, the end of the outermost tube nearer the valves is fixed and the bar 27, regulating the lift, is attached to the valve itself which is screwed on its controlling-rod 22. In another form in which a similar regulating-device is employed, one tube only is used, the end farther from the valves being free.
