Patent GB-190013640-A (GB)
Title: Improvements in Pantographic Apparatus for Producing Copies of Sculptures, Carvings, Carved Figures, Ornamentations and other Devices in Stone, Wood or other Material.
Inventor: DENNY FRANK
Filed: 1900-07-30
Granted: 1901-07-30
Abstract: 13,640. Denny, F. July 30. Pantographs.-Relates to pantographic apparatus for producing to scale copies of sculptures, carvings, and solid ornamental work generally. Within a frame A, B, C, D, a rectangular frame E', E<2> is mounted to turn about an axis G. On the frame are mounted two pairs of racks H<1>, H<2> and J<1>, J<2>. These racks are moved simultaneously in opposite directions by a hand-wheel and spur gearing I<1>, I<2>. One rack carries a balance weight L, while the other carries a shaft x, upon the end of which the cutting or shaping tool is fixed. A tracing bar or shaft y is connected to the shaft x, and also to the shaft G by a pantograph linkage, so that, as the shaft x is moved to and from the shaft G, the shaft y has a corresponding motion on a reduced scale. The motion of the shafts x and y in the direction of their lengths is effected by means of a slotted arm e pivoted to the shaft G and engaging with the arms x and y. When this arm is rotated by a treadle acting through a rope, the tracer and cutting-arm are forced against the work, and the motion takes place in the same ratio as that due to the pantograph. When a bust, say, has to be copied, it is placed on a stand opposite to the end of the tracing- shaft y. A block of stone is similarly placed opposite the end of the cutting-shaft x, which is fitted with a drill driven by a flexible shaft. Then the bar e is rotated until the end of the shaft y comes in contact with a point on the bust being copied. During this time the drill on the shaft x enters the block of stone to a corresponding depth. By the operation of the gear I<2>, or the rotation of the frame E<1>, E<2>, the shaft y is brought opposite a second point, and the operation repeated. When the work has to be reproduced on practically the same scale, the shafts x and y are too close to allow of the necessary space for the bust &c. In that case, therefore, the motion of the shaft x is transmitted to a second shaft fitted in a horizontal frame M<1>, M<2>, which slides on an upright P. For undercutting work, the drill &c. is mounted on the end of the shaft x at the necessary angle, and a corresponding tracer is fitted to the shaft y. In this arrangement, the simultaneous adjustment of the cutting-drill and the tracing-point about the respective axes of the shafts x and y is effected by chain gearing.

Title: Improvements in Locks for Doors and the like.
Inventor: BURGUY JOSEPH MARCEL
Filed: 1900-08-09
Granted: 1900-10-06
Abstract: 14,295. Burguy, J. M. Aug. 9. Locks, key; latches.-The lock is illustrated as applied to a pair of folding doors. The case is thin, and of ornamental appearance. The latch bolt a is operated by the follower e and by the spring f, which is of the special shape shown in Fig. 2. The follower e is operated by handles on a spindle passed through the aperture d, or the handles may be dispensed with and a projection a' formed on the key, Fig. 3, to fit this aperture. The lock bolt m is controlled by a lever r, and is operated from outside by a key and from inside by a stud t. The bolt m may be shot behind the bolt a, to lock it, or into a notch l to hold it in the retracted position, in which case the doors might be used as swing doors. The bolt m may also be placed by the stud t in an intermediate position, in which case it locks the bolt a and cannot be retracted by the key. It is retained in the intermediate position by teeth x on a flange on the lever engaging corresponding teeth on the edge of the bolt, under the influence of the spring y. Fig. 7 shows a modification, in which the bolt r<1> is operated by a key from either side. If the bolt is placed in the intermediate position, the key, which is still in the keyhole, cannot be displaced from the opposite side, as the spring y, which is attached to the bolt and engages in the notch b<1> in the lever, resists any attempt to work it round.

Title: Improvements in Machines for Drying or Withering Tea Leaf and the like.
Inventor: BEGG JAMES
Filed: 1901-09-10
Granted: 1902-06-12
Abstract: 18,081. Begg, J. Sept. 10. Drying tea.-A chamber for drying or withering tea leaf by natural heat is shown in Fig. 6. A series of rollers J is arranged at each end of the chamber, and the rollers are provided with webs of cloth &c. I, each having a terminal lath I<1> connected by a cord &c. K to a winding-pulley L. The webs may be supported on two or more wires and on intermediate rollers M. The end rollers and pulleys are provided with suitable gearing such as bevel gear o, Fig. 9, rotated by disconnectible bevels P on vertical shafts Q, and ratchet devices S' on the rollers allow them to be locked when required. In operation, the lowest web is pulled through the chamber, and an even layer of tea is deposited on it by a spreader A. Each web is charged in turn, two spreaders being used for a double-ended apparatus, as shown, but a singleended arrangement may be used. The spreaders consist of a hopper A', Fig. 1, having rotary feedrakes B and four linked rocking-shafts D carrying rakes. The shaft may be adjustable. The rocking rakes have teeth which may be adjustable and of different lengths. The spreader may have a pair of hanging aprons to quieten the discharge. Such a spreader may be used for an artificial drying- apparatus in which the tea is spread on the uppermost of a series of overlapping endless bands V, Fig. 13, which are mounted on intermittentlyrotated rollers U*, so that the tea descends stepwise. The tension of the bands may be adjusted by the rollers being carried in adjustable bearings. Fans draw hot air through the chamber, and the air first passes through an endless band Y, moistened by its lower end dipping into a trough, and then passes through an entrance chamber V having porous walls which allow external air to enter. The porosity of the walls is varied according to the state of the atmosphere, and they may be coloured. Additional hot air may be introduced into the chamber by pipes b with bell-mouthed openings c or other means.

Title: Improvements in or relating to Telegraphic Apparatus.
Inventor: CREED FREDERICK GEORGE
Filed: 1902-01-14
Granted: 1903-02-14
Abstract: 1061. Creed, F. G., and Coulson, W. A. Jan. 14. Telegraphs.- Relates to a telegraphic receiving- apparatus in which the message is received as a perforated strip. The signal currents are received by polarized magnets c, c. The cores b of the polarized magnets are extended to form stops for oscillating armature levers d, which are employed t o operate the valve in connection with a fluid - pressure motor n. The piston n<1> of the motor is provided with arms arranged to operate bell-crank lever s 12, to which are attached punch strikers 14, 15. The levers 12 are oppositely pivoted, so that, when one punch striker is advanced, the other is withdrawn. Each punch striker is provided with a swell 19, by which it is thrown out of the line of its stroke as it comes in contact with a roller 18. The heads 1<a>, 2<a> of the punches 1, 2 are bevelled, so that they easily free themselves from the punch strikers. The punches are mounted in a sliding frame 21, and the rear ends of the punch strikers are arranged to engage with a flange 23 on the frame 21, so that, as the inoperative punch is withdrawn, it causes the frame 21 to move backwards and withdraw both punches. The arms which move the levers 12 are arranged to engage with a spring arm j<1> by means of stops j<2>. The arm j<1> is connected to a link j attached to the locking-rod, by which the oscillating armatures d are held against their magnets alternately. The armatures d are provided with non-magnetic extensions u, carrying strikers s, for operating the slide-valve rod p of the motor n. The paper-strip feed-wheel 4 is provided with a synchronizing-wheel 32, and is driven by a friction clutch from the motor 5. The wheel 32 is adjusted to position by a synchronizing-rod 33 on each operation of the punches. In a modified method of synchronizing, one of the levers 12 is provided with a detent rod for operating either of two pivoted syncbronizing-arms for engaging with the wheel 32. Instead of the frame 21, each of the punches may be withdrawn by means of a withdrawal arm attached to a link, provided with lost motion, engaging with a pin on its lever 12. Instead of the extensions u for operating the motor slidevalve rod p, the rod may be provided with a spring tripping-device, each motion of the piston-rod setting the slide-valve rod p in position for the next operation. In another form a separate relay circuit may be employed, in which the motion of a separate magnet armature controls the rod p. The slide valve may be such as that described in Specification No. 12,406, A.D. 1900, [Abridgment Class Steam engines].
Patent GB-190208312-A (GB)
Title: A Device for Recording the Position of Signals and the Operations of the Engine Driver whilst Trains are Passing the Signals.
Inventor: BRAAM JACQUES PIERRE DE
Filed: 1902-04-09
Granted: 1902-07-31
Abstract: 8312. Braam, J. P. de. Oct. 9, A.D. 1901, [date applied for under Patents Act, A.D. 1901]. Signals on eng i n e s ; recording signals ; indicators and repeaters, signal.-Relates to a recording - mechanism, mounted on the engine, for showing when a train passes a ' danger' signal, the apparatus also serving to show the action of the driver in re-setting the apparatus &c. The apparatus is shown mounted on the box c of the disc indicator which forms part of the signalling and train-stopping mechanism described in Specification No. 7626, A.D. 1901, and is actuated by the cam a on the indicator spindle b, but any suitable actuating-mechanism working in conjunction with the signals may be employed. The record is made by the style d on a sheet of paper carried by the roller e. The style is carried by the lever f, and is normally held out of contact with the paper, against the action of the spring i, by the spring- controlled rod j, which is slotted at its lower end to receive the arm m of the lever n, m actuated by the cam a. The roller e is capable of longitudinal movement on its spindle 9, which carries a pinion provided with a rod 10 for rotating the roller. A fixed rack on the frame gears with a worm on the roller, to effect the longitudinal movement of the latter during its rotation. The pinion on the spindle 9 is geared to and driven by a clock train 7, 5, 2, &c., which is normally held at rest by the spur y on the stop-lever s, t engaging in a notch in the wheel r, the stop-lever being held in operative position by the spring-controlled lever v. When the engine passes a ' caution' (or ' distant') signal set at danger,' the spindle b is rotated, so that the part 13 of the cam a actuates the lever n, m to draw the rod j down, thereby releasing the lever f and permitting the style d to make contact with the paper. During this movement, the hook z on the lever f disengages the lever t, s from the wheel r, and moves the lever v clear of the controlling- fly 14, so permitting the clock train to start the roller e. The record made on the paper consists of a helical line 17 (or 19) shown in development in Fig, 5, and continues until the driver re-sets the apparatus by means of a lever on the spindle b &c. If, after re-setting the apparatus, the driver also runs past the stopping' signal while it is at ' danger,' the style is brought into contact with the paper by the part 13 of the cam a, and is removed from contact with the paper when the part 18 of the cam comes into engagement with the lever n, the spindle b having a greater movement of rotation than when the ' caution' signal is passed. In this case, the record consists of a dot 20. If, when the 'stopping' signal is at 'danger,' the signalman has failed to set the 'caution' signal to the corresponding position, the recording-apparatus would be actuated only at the 'stopping' signal, the record 21 made in such a case showing the fault of the signalman.

Title: Improvements in or relating to Type-writing Machines.
Inventor: SOBLIK MAX
Filed: 1902-10-24
Granted: 1902-12-18
Abstract: 23,289. Soblik, M. Oct. 24. Type-writers.-Relates to improvements in the machine described in Specification No. 21,504, A.D. 1899. From the base of the machine rises a fixed shaft g, in which are formed passages h, i, both of which are always in communication with a passage o in an arm n. The arm n is rigidly connected with the type-wheel m. The type-wheel and arm n are continuously rotated by means of suitable mechanism, and the open end of the passage o registers in turn with ports f from which tubes c proceed to the keyboard. Compressed air is supplied through the passage h, and, as the air can find an outlet through all the perforated keys a in succession the pressure is not transmitted through the passage i to the cylinder l. When, however, the operator closes the aperture in one of the keys with his finger, the passage of air is stopped at the instant that the rotating arm n comes opposite the corresponding port f. Pressure is then transmitted to the cylinder l, which puts in motion the devices for striking the types, moving the platen, &c. The passage h may be connected with a vacuum chamber instead of a compressed-air reservoir.
