Abstract: 24,760. Samuel, H. Nov. 11, Fog and audible signals!; signals on engines and trains contacts, mechanical. -In the apparatus for signalling on railways shown in Figs. 1 and 2, the rail 2 arranged on the track transmits to the locomotive or train the indications of the ordinary track signal 3, so that, if the signal is at danger, and is invisible, as by fog, the indication cannot pass unnoticed. The movable attachment on the locomotive or train, instead of operating a dial-indicator or the like, may be used to control an audible signal, or the brake, or the like. The sections of the rail 2 are independently movable, and each section is elevated normally by a counterweight 10. The movable locking-bar 11 is connected to the controlling-mechanism of the signal, and locks all the rail sections in their elevated position when the signal is at danger. The locking- bar 11 has slots 13, into which the levers 8 engage, and is jointed to the rocking lever 14, which is held immovable by the abutment 16 when the signal is at danger. On the locomotive or train, one or more rollers 18 are pressed downwards with sufficient force to depress the rail-sections when not locked. The locomotive may be fitted with two boxes 28, Fig, 6, sliding in the slide-ways 27 and carrying the axles 29 on which are mounted the weighted levers 30. The rollers 35 are carried by the levers or rods 34 and the roller axles are connected by the frame 36, which, together with the rollers 35, is lowered by the pneumatic cylinder 41. The boxes 28 are adjusted over the proper rails. The fixed inclined plane 17 at the beginning of each signal rail 2 may be used to rotate a dial on the engine indicating the apparatus passed. At switches, station approaches, and the like, the rails 2 are provided with gaps for the switch tongues and crossings. One section of the signal rail may be rendered immovable independently of the bar 11 by means of the rotatable segment 22, which is connected up to the signal.

Granted: 1903-05-07
Abstract: 6312. Drõger, J. H., and Drõger, A. B. March 18. Inhalers. - In inhalers, more particularly for the administration of chloroform, ether, &c., in which the medicament is vaporized by a current of air or oxygen, provision is made for regulating the dosage and for preventing unintentional overdosage. The chloroform, ether, &c. is contained in a vessel n, Fig. 1, provided with a siphon tube g which opens into a glass vessel f forming a visible dropping-chamber. Oxygen from the bottle a is led through a reducing-valve b into the tube c which terminates in an atomizing-nozzle d. The action of the issuing jet creates a partial vacuum in the chamber f, thereby causing the chloroform &c. to drop from the tube g and be carried as vapour along the tube m to the mask l. The degree to which the chamber f can be rendered vacuous is determined by the cock i in the pipe h which opens either to the atmosphere or into the pipe m. The supply of oxygen can be shut off by the cock p, so that overdosing owing to re-starting of the apparatus is rendered impossible. The tube g may be surrounded by a shielding tube furnished with a fine gauze inlet sieve. A storage bag q, Fig. 5, of leather or the like may be interposed between the pipe m and the mask l. Its exit passage r is covered by a non-return valve u which is used when the patient coughs, and during expiration.

Title: Improvements in Apparatus for Charging Horizontal Gas Retorts.
Inventor: GIBBONS WILLIAM PIKE
Filed: 1903-06-08
Granted: 1904-05-12
Abstract: 12,820. Gibbons, W. P., and Gibbons, G. B. A. June 8. Gas retorts.-In charging horizontal gas retorts by means of a vertical or inclined shoot, of the type described in Specification No. 10,414, A.D. 1895, the speed acquired by the falling coal is accelerated by means of an endless band. The band E, which is driven by a motor J, is arranged below the mouth a' of the shoot A', A<2>, and is carried on pulleys F<1>, F<2> in a frame G which can rock about the axle H<2> of the pulley F<2>. The bearing blocks h<1> of the axle move in vertical guides M<1> to suit the height of the retorts I<1>, I<2>, &c., and the frame, with its accessories, is counterbalanced by weights N and fixed by means of hooks, which engage a chain n<1> carrying the weights N. The lower part A<2> of the shoot slides in the upper part A<1> and is counterbalanced by a weight a. To allow for the movement in an inclined direction of the part A' when the frame and shoot are raised, side brackets a<6>, fixed to the part A', move along rollers h<5> carried by the bearing blocks. To prevent the coal spreading, the edges of the band are turned up by means of inclined side rollers. The counterbalance weight g' of the frame may be moved along a lever g<2> in order to vary the trajectory of the coal. Rollers r' are arranged on the sides of the shoot to make contact with the band when the frame is raised. In a modification, the band replaces the bottom of the curved part of the shoot. For this purpose, the band passes over an additional pulley, arranged above the pulley F', and its shape is made to conform with the curved sides of the shoot by means of several small guiderollers, or one large pulley, placed on either side. The Provisional Specification states that a friction brake may be arranged to act upon a drum mounted on the pulley shaft, and that speed cones may be employed to regulate the speed of the band.
