No. 22728.—18th May, 1906.—HORACE WALTER DOVER, of Holyrood, St. James, Northampton, England, Engineer. Improvements in pneumatic tires.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) In a wheel provided with a pneumatic tire and side flanges embracing the body of the tire, the employment of a pair of side flanges of such cross-sectional configuration as to cause the tire to present internally a pair of circumferentially extending lateral enlargements of the central air-space, so as to permit of the tread portion of the tire yielding under the load by passing freely inwards between the free edges of the flanges, as specified. (2.) The combination with a vehicle-wheel provided with a pneumatic tire, of a pair of side flanges adapted to embrace the body of the tire, each of said flanges being approximately semicircular in cross-section so as to cause the tire to present internally a pair of circumferentially extending lateral enlargements of the central air-space, for the purpose specified. (3.) A pneumatic tire or tire-cover for use in the construction specified in claim 1, having a cross-sectional configuration adapted to fill the space between the periphery of the rim and the side flanges thereof, and to project radially between and beyond the free edges of the flanges, substantially as specified. (4.) In the construction specified in claim 1, providing the felloe or rim with a circumferentially extending peripheral band, the edges of which extend beyond the sides of the rim so as to be adapted to become imbedded in the cover of the tire when the cheek-plates are bolted on each side of the rim, substantially as and for the purpose specified. (5.) The employment, in combination with the construction specified in claim 1, of a detachable tread-band for the tire, provided at its lateral edges with beadings or projections adapted to engage in recesses or apertures formed in the flanges so as to become positively interlocked between the tire and the flanges, substantially as and for the purpose specified. (6.) The combination with a tire having a twin tread, and constructed substantially as specified in claim 1, of an inextensible band encircling the tire so as to prevent the mutually adjacent sides of the treads from being blown outwards by the air-pressure within the tire, said band being of approximately the same diameter as the free edges of the flanges, as specified. (7.) The several constructions of wheel-rims and pneumatic tires in combination therewith, substantially as described with reference to the respective figures of the drawings, for the purpose specified.

No. 22729.—24th April, 1907.—THEOCTISTE POLJAKOFF-KOWTUNOFF, of Tjora, St. Petersburg, Russia, Manufacturer. Vehicle with automatic movement of rails.

Claims.—(1.) A vehicle with automatic movement of rails, consisting of a combination of a vehicle-frame, several axles on which the frame rests, several pair of disc-formed wheels with cut-off sides set on these axles, interior and exterior rails connected with sleepers, and an arrangement connected with the rails and with the frame of the vehicle, and serving to lift and move the rails, the travel of the vehicle taking place alternately on the interior and on the exterior wheels, and during the movement on the interior wheels the exterior rails with the sleepers are raised and moved and vice versa, substantially as set forth. (2.) In a vehicle with automatic movement of rails mentioned in claim 1, the use of turntables arranged as jacks for changing the direction of the vehicle’s movement, substantially as set forth.

No. 22736.—13th June, 1906.—EDGAR SHAW, care of Keep Brothers, of Great Charles Street, Birmingham, England, Tailor. Improvements relating to tailors’ hair-cloth and like materials.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claim.—A composite stiffening-fabric, comprising strips of wool or other suitable extensible yarn alternately arranged with strips of inextensible cotton, linen, or like yarn, and interwoven transversely with horsehair, imitation horsehair, fibre, or similar material, substantially as described.

No. 22755.—4th May, 1906.—VINCENT LITCHFIELD RAVEN, of Alpine Cottage, Darlington, Durham, England, Engineer. Improvements in railway signalling-apparatus.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Extract from Specification.—For enabling the driver of a locomotive engine to determine in foggy weather the position of the line-signals designed to control the working of the line over which his engine or train is travelling it has heretofore been proposed to provide on the track in advance of the line-signal a conducting-bar which, when rubbed over by a pair of brushes carried by the engine, closes the circuit of an electric battery through an electric bell or other alarm on the engine, and thereby brings such alarm into operation to indicate to the engine-driver that he is approaching a signal; and for indicating when the line-signal is in the “safety” attitude it has been proposed to provide on the engine a separate bell or other alarm, and on the track, also in advance of the signal, either a movable bar or a second stationary bar, for closing, when the engine runs over it, the circuit of a separate electric battery, that is under the control of the signalman, through the second electric bell or other alarm and a brush or brushes connected to such second bell or alarm. With such an arrangement, however, two sets of bells or other alarms are necessary, and the danger alarm is only sounded whilst the engine is passing over the first bar, and therefore may be overlooked or forgotten. It had also been proposed to provide on the engine one audible and several visual signals for indicating “danger” or “line clear” when approaching a line-signal, the operation of such audible and visual signals being effected by the closing of different electric circuits by two brushes on the engine moving in contact with two sets of movable contact-bars or rails arranged on the track and adapted to be operated by the signalman, and to be connected by him to a battery in the signal-cabin, the electric circuits being completed through insulated portions of the track-rails over which the engine runs, but the arrangement is very complicated and necessitates the use of many moving parts. Now, an object of the present invention is to simplify and cheapen the construction and insure reliable and safe working of signalling-apparatus for the purpose set forth, and at the same time avoid any necessity for insulating portions of the track-rails. For this purpose there are provided on the engine or other vehicle (hereinafter referred to as the “engine”) a visual signal, an audible signal, and electromagnetic apparatus for controlling the two signals, and on the track, in the neighbourhood of and behind each line-signal or signalling-point which it is desired to indicate to the engine-driver, are arranged separate longitudinal metallic bars, one of which is independent of the line-signal or signalman, and the other or another of which, that is nearer to the signalling-point than the first one, is under the control of the line-signal and signalman, the arrangement being such that upon the engine approaching the signalling-point both the visual and audible signals will, by reason of the presence of the first bar, be first operated so as to indicate danger and call the attention of the driver to the fact that he is approaching a signalling-point, and will continue to give such indication after the engine has passed over the said bar, and also when it is passing over the second bar if the line is blocked, so as to necessitate the engine being brought to rest, whereas should the line-signalling apparatus have been operated by the signalman to indicate “line clear,” either before the train passes over the first bar or before it passes over the second bar, this latter bar will, upon the engine running over it, cause the visual signal to be automatically returned to its normal or “line-clear” position, and the audible signal to cease sounding, thus indicating to the driver that the line is clear so that he may continue to advance.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
