over the switches or shifting rails; on the removal of hisfoot from the stirrup and his hand from the switch lever,the signals re-adjust themselves, the arms standing outat right angles, and the lamps “red,” stopping bothlines.
Model of a double station signal, provided with anarm and lamp working simultaneously on each side of thepost, to command both lines by moving either of thehand levers.
610 De Fontaine Moreau, Peter A., 4 South Street ,Finsbury —Importer and Proprietor.
Vidie’s patent Warner, an apparatus intended to beplaced above carriages, from which metallic plates descendinto the carriages, indicating the name of the place orstation towards which they are proceeding, or are stopping.On one side of the carriage an apparatus is intended to beplaced, which can be put in action from the inside of thecarriage, and serves to give an order or warning to theguard. At the time of starting all the metallic plates ofa train can be reversed by turning a crank arm for thatpurpose; and the apparatus closes simultaneously withthe door of the carriage.
614 Hoby, James "Ward, Renfrew, near Glasgow —Inventor and Manufacturer.
Patent system of permanent way for railways, com-prising a length of 18 feet of single line, with double-headed rails, cast-iron longitudinal sleepers, folding keys,and cross ties. The following cut represents a crosssection of this permanent way.
A is the rail, and B the folding-key. The part C isa cast-iron piece, with a stirrup, or recess, cast throughit, which holds the wrought-iron bearer, and receives inthe stirrup a wrought-iron cross-bar, D, set on edge, forthe purpose of securing the gauge and the tilt of the rails.
Two cast-iron longitudinal sleepers reversed, to showthe mode of securing the tie-bar.
Specimen of • the folding keys applied to an ordinarychair and double-headed rail.
Specimen of a wrought-iron sleeper, with cast-ironfolding keys, applied to a double-headed rail.
615 Greaves, H., 4 Ordsall Terrace, Manchester —
Inventor.
Iron surface-packed railway sleepers, with rails; a sub-stitute for wood-sleepers.
[The decay to which the timber substructure of rail-ways is subject renders the substitution of some inde-structible material advisable, even presuming the firstcost to be greater.—S. C.]
616 Samuel, James, C. E., 3 Duke Street, Adel-phi —
Inventor.
Patent cast-iron, timber-bedded, wedge-trough perma-nent way for railways.
Patent fish-chair, or improved joint-chair, applicable toexisting railways without removing the present sleepers;and giving continuity to the rails.
[There are two kinds of rail-bearings, the chair bearings,and continuous bearings for rails.
With chair bearings the rails are supported at fixedpoints, from 3 feet to 4£ feet apart, the rail bridgingnear the intervals.
With continuous bearings the rails are laid or beddedupon timbers, termed sleepers, which are in their turnbedded upon the ground, or rather, upon that preparationof the railroad for the permanent way, ballasting. Theconnection between the rail and the sleeper is made sothat the two act together, and are borne in every partalike by the ballast.
A transverse tie is required to keep the rails in gauge,or immoveably at the same distance apart; as the conicalform given to the face of the tire of the bearing wheels ofrailway carriages, to enable them to run upon curveswithout dragging, induces a constant effort to force rails.At low speeds, this tendency is not felt; but at highspeed, this derangement is very manifest. The sleepercommonly used is of timber in the log, cut into twohalves, so as to present its section uppermost, and itsround hard surface to the earth. The joint chair isintended to secure the abutting ends of the rails.—W. H.]
Patent improved “donkey-engine,” for pumping waterinto steam boilers, to be used in locomotives instead ofthe present “feed-pumps.”
Sectional model of patent double-cylinder “ continuousexpansion” steam-engine, in which the steam is made toexhaust from the first to the second cylinder, the cranksbeing set at right angles.
618 Dunn, T., Windsor Bridge, near Manchester —Inventor and Manufacturer.
Apparatus for removing carriages from one line of railsto another. The following cut represents an end view ofa traversing machine, patented by the exhibitor, and isshown in the act of removing a carriage from one line ofrails to another. The principal feature in the inventionis the rail or shelving at the lower edge of the machine.In the engraving the carriages are mounted thereon byeasy inclined planes, A A, attached to the end of thetraverser, and working inwards and upwards at the sametime on spiral joints.
Dunn’s Patent Traversing Machine.
Models, to scale, of traversing machine, being modifi-cations of the same; with drawings.
