A pointer upon a signal post is raised, and maintained at a certain height by a train of wheels, actuated by a weight, which is wound up once in 24 hours. The engine in passing detaches the pointer from the wheel work, and the pointer descends to the lowest point, but when the train is past, the wheel work again slowly elevates the pointer, and by the position of the pointer, the driver of the succeeding train can judge how far the preceding train is ahead of him. 28th Jan. 1841. W. Gall. Certain improvements in the construction of locomotive engines, and of the carriages used on railways, applicable in part to carriages used on common roads.
28th Jan. 1841. W. C. Harrison. Improved turning table for railway purposes.
An arrangement of anti-friction rollers round the central post which supports the table.
1st Feb. 1841. W.W.Taylor. Improvements in buffing apparatus for rail way purposes.
Applying a series of layers of felt to the ordinary buffer head, or to a board extending across the whole breadth of the end of the carriage frame, and covering the felt with leather or other water-proof material.
3d Feb. 184.1. J. Bunnett. Certain improvements in locomotive engines and carriages.
An improved steam regulator, five different sorts of brakes, and an axle-guard, which allows a compensating movement when the wheels are traversing curves.
8th Feb. 1841. E. Oldham. Certain improvements in the construction of turning tables, to be used on railways.
8th Feb. 1841. J. Scott. Improvements in constructing railways,and in propelling carriages thereon, which improvements are applicable to raising and lowering weights.
A series of cog wheels placed at short intervals along the centre of the railway, and driven by stationary engines, give motion to the carriages by means of a rack attached to the under side of the carriages.
Casting railway chairs by means of metal side plates and metal cores in sand moulds. Forming wooden pins and wedges, by forcing them into metal moulds, and heating them whilst under compression, till the elasticity of the wood is sufficiently overcome. See further at page 421.
22d March, 1841. Thomas Wright. Certain improvements applicable to rail way and other carriages.
Improvements in brakes, axle-trees and boxes, carriage springs, safety flanges on the outer edge of the ordinary flange on railway wheels, hollow steel spokes, and an elastic plate to serve as a brake, a sledge and a buffer.
17th April, 1841. P. Kendall. Improved method or methods of connecting and disconnecting locomotive engines and railway carriages.
The connecting link from the tender is received between two elastic metal plates, and a stud projecting from each side of the link, passes through holes in the ends of the plates, and so long as the pull is in a direct line, the link is firmly retained by the plates, but if the strain should become oblique to the elastic plates, the link is released.
11 th May, 1841. E.Taylor. Certain improvements in the construction of carriages used on railroads.
Constructing the roofs and pannels of railway carriages of papier māche; affixing to one wheel a solid axle, which revolves in a hollow axle affixed to the opposite wheel, and forming wheels with segments of wood or of papier māche within the tire.
20th May, 1841. John Carr. Improvements in apparatus for retarding and stopping railway carriages.
22d May, 1841. Joseph Woods. Certain improvements in locomotive engines; and also for certain improvements in the machinery for the production of rotatory motion for obtaining mechanical power, which improvements in machinery are also applicable for raising or impelling fluids.
Employing loose wheels on locomotives, in order to traverse curves more easily; improved lubricator; improved reversing gear; connecting a whistle to the blast pipe to give a constant intermittent whistle in a fog; improved swivel joints to the water pipe of the tender, and a rotatory disc engine.
5th June, 1841. J. Gibbs. Improvements in roads and in railways, and in the means of propelling carriages thereon.
A mode of propelling railway carriages by fixed engines.
23d June, 1841. R.Stephenson. Certain improvements in the arrangement and combination of the parts of steam engines, of the sort commonly called locomotive engines.
1. Lengthening the cylindrical portion of the boiler, so as to admit the three axles of six-wheeled engines to be placed beneath the cylindrical part of the boiler, and between the front of the fire-box and the back of the smoke-box.
2. Improvements in the slide valve and reversing the gear; and
28th July, 1841. A. B. Von Rathen. New method or methods, called by the inventor "The united stationary and locomotive system," of propelliug locomotive carriages on railways and common roads, and vessels on rivers and canals, by the application of a power produced or obtained by means of machinery and apparatus unconnected with the carriages and vessels to be propelled.
9th Dec. 1841. J. Edwards. Improvements in giving signal on railways.
