Title: Improvements relating to the Manufacture of Self-sealing Pneumatic Tires.
Inventor: HADDAN HERBERT JOHN
Filed: 1903-02-03
Granted: 1903-04-23
Abstract: 2603. Haddan, H. J., [Blodgett, J. W.]. Feb. 3. Tyres, pneumatic.-Relates to the manufacture of pneumatic tyres provided with self-sealing portions. In the form shown in Fig. 6, the metallic tube 34 is surrounded by a thin rubber tube 35 over which is drawn the larger thin rubber tube 36 and outer cover 38. After the parts, thus arranged, have been enclosed in the trough 33 and its lid 39, heat is applied and self-sealing material is pumped in between the two tubes 35, 36 until it extends all round the tyre, the distance between the inner and outer metal parts being adapted to give the desired thickness of self-sealing material. The self-sealing material may, however, be limited to a pocket, as in the form shown in Fig. 1 which is manufactured by winding around a mandrel 10 a thin sheet 9 of unvulcanized rubber having a layer 12 of pulverized soapstone between a part of the coils. If an air tube with closed ends is required, the tube is nowvulcanized, and, after a layer of self-sealing material has been placed in the pocket formed between the coils, the ends are sealed. If a continuous air tube is required, a short unvulcanized rubber tube 14, Fig. 2, is fixed inside the abutting ends of the inner coil which is then inflated. A strip 16 of unvulcanized rubber is wrapped round the ends of the outer coil, and, after a pipe 17 has been connected to the pocket, the whole is vulcanized in a circular channel-shaped mould 26, Figs. 4 and 5. The pipe 17 and the inflating-valve project through apertures 27, which are normally closed by removable blocks 29, and near the pipe 17 is a block 30 which compresses together the rubber layers. After the parts have been heated, self-sealing material is forced into the pocket through the pipe 17, and as it gradually extends along the pocket the air escapes through a small hole 31. A similar channel-shaped mould for air tubes with closed ends is straight and has a hinged lid, which is held at the distance required to give the proper thickness to the layer of selfsealing material.

Title: Improvements relating to Gas or Vapour Electric Apparatus such as Mercury Vapour Lamps for Lighting or other Purposes
Inventor: TALL FREDERICK WILLIAM LE
Filed: 1903-06-25
Granted: 1904-04-28
Abstract: 14,166. Le Tall, F. W., [Cooper-Hewitt Electric Co.]. June 25. Vacuum tubes.-For starting a mercury vapour lamp, a high-potential discharge is produced by interrupting the current through an electromagnet. In the arrangement shown in Fig. 1 (Comp.), the attraction of the armature 40 breaks the shunt circuit 37, in which are included a resistance 43 and a time-limit circuit breaker or fuse 44. The latter prevents repeated action of the electromagnet owing to the failure of the lamp. In a modified arrangement, a snap switch is operated by an armature mounted on a spindle between the poles of a horse-shoe electromagnet, so that, when not in use, the switch is closed by a spring. In the Provisional Specification an arrangement is shown, in which a Wehnelt interrupter is used in place of the resistance and the circuit breaker or fuse is dispensed with. Fig. 1 (Prov.) shows a different arrangement of circuits. The reactance coil 22 is short-circuited after starting by the armature 31 of the electromagnet 30, and the circuit-breaker 27, which may be of any known quick-break form, is shunted by a condenser 28. On closing the switches 27, 29, the current flows through the coil 22. On opening the switch 27, the selfinduced current from the coil passes through the lamp and starts the main current.

Title: An Improved Fabric.
Inventor: STRANG WILLIAM
Filed: 1903-07-04
Granted: 1904-04-21
Abstract: 14,872. Strung, W. July 4. Corded fabrics; tissuefigured fabrics.-A fabric is woven inverted with a plain ground, and tapes formed by subsidiary warp threads C, D and whip threads E woven on it at right-angles to its surface. The threads E are operated by lappet needles, and the subsidiary warp threads, of which there may be more than two, are operated similarly or otherwise between the reed and the lappet needles. The needle of the thread E rises between the warps C, D into the ground shed on the right of a ground warp B, and, after a shot of weft A, it is lowered again. The warp threads C, D are then moved transversely, and the whip-thread needle is moved to the left so that it passes round the thread D and rises between the threads C, D and on the left of the adjacent ground warp to the left. This operation is ropeated shot about, or every second shot as desired. The whip-thread needle may be raised and lowered without transverse movement, so that the whip thread passes between the same two ground warps. The whipthread needles and the mechanism operating the subsidiary warps may be moved transversely to any desired extent to form a pattern other than straight.
Patent GB-190316720-A (GB)
Title: Improvements in or in connection with Power Hammers
Filed: 1903-07-30
Granted: 1904-06-02
Abstract: 16,720. Pilkington, Ltd., P., and Gibbs, G. J. July 30. Hammers, power.-The hammer cylinder A is put into communication with a continuously-acting air pump B by means of a valve H with three ports J, K,L which communicate with ports C, D, F in the seating. When the valve is turned so that the port L is opposite the port D, air passes freely between the cylinders A, B and the hammer works. When ports K, D and J, C coincide, air is drawn into the pump from the atmosphere, but cannot return past the valve M and is forced into the hammer A past a valve N, thus holding down the hammer. When the valve is in the position shown, air is drawn out of the hammer past the valve M, and the hammer is consequently held up. The valve is turned by a weighted treadle, so that, when at rest, it is in the position shown in Fig. 1, and a tooth S, Fig. 5. on a wheel Q on its spindle bears against a stop U ; for working, the tooth R is brought against U, and for holding the hammer down the lever Z carrying the stop U is depressed so that the weighted treadle brings the tooth S against the stop, A non-return valve P prevents air above the port D from escaping from the cylinder A. A flat valve may be used, and springs may take the place of the weights, on the lever Z and treadle ; the hammer may be double-acting.
