 of the sleam pipe A, which is only used where two engines are in use, and is 

 afterwards wasted through an air pump and condenser attached to the second 

 engine. This system of supplying cylinders with the same steam can be ex- 

 tenile.l to more than two cylinders when it may be required. 



The second improvement is for the formation of a boiler having two or 

 more fuinaees. with the flues carried by a curved flue into a horizontal flue 

 stretching across the boiler at right angles to the furnaces, and then carried 

 up into a single chimney, as shown in the drawings annexed to the specifi- 

 cation. 



DOOR AND WINDOW FASTENINGS. 



WiLu.v.M Bewi-f.y, of Dublin, gentleman, for •' improvements in fastenings 

 for doors, windows, and other places, wli^te fastenings are used.^* — Granted No- 

 vember 2. 1844 i KnroUed May 2, 184.5. 



The object of the inventor is intended to arrange the parls of a lock for 

 fastening doors, windows and oiher places in such a manner that the bolt of 

 such lock may be set free by the act of closing the door, and thereby faslen 

 the .same, and that by the moving of the bolt in order to open the door, shall 

 bring the bolt in such a position as to be held by certain mechanical arrange- 

 ments. The bolt of the lork simply consists of a latch or lever bolt, which 

 is constantly forced oiitwartls by means of a spring, the length of movement 

 being regulated by a pin or stop, there is also a spring which, when the bolt 

 is moved back for ihe purpose of unfastening the door, which is done by 

 means of a handle, that reiaius ihe bolt in such a position until it is moved 

 out of the way, which is ell'ected by means of a projection fixed on the strik- 

 ing plate, against which projection tlie spring comes when in the act of clos- 

 ing the door, and immediately this spring is acted upon, the bolt is released 

 80 SB to faslen the door. 



DRESSING 0KK5. 



Wii.i.iAM Bruston, of Pool, near Truro, Cornwall, for " Improvements in 

 apparatus /or dressing ores.''— Gtanlemov. 2, 1844; Enrolled M,ay, 1845. 



This invention consists of an improved method of submitting ores or male- 

 rials containing ores to the action of a stream of water, by depositing them 

 upon an inclined table, moveable either continually or occasionally upward 

 against the stream, whereby the waste is (as in the ordinary methods prac- 

 tised) washed ofl'at the bottom of the incline, whilst the clean or dressed ore 

 by ils superior gravity, settles upon the moving table and with it is carried 

 upwards beyond the influence of the washing stream and ultimately deposited 

 into a separate vessel. 



The means by which the same is performed is as follows: an inclined 

 moveablo table is made with a long sheet of painted cloth w ith the two ends 

 united, when it Ijecomes an endless band, along each edge and on the outer 

 side is sewed a strip of thick woollen clolh enclosing a solt hempen rope, 

 which forms a ledge or margin to prevent the materials being washed over 

 and for the transverse sujiport of the cloth are fixed slight pieces of timber 

 extending the whole width of the clolh inside, and at eipial and short dis- 

 tances, by copper nail.s driven through the said margin into the transverse 

 pieces of timber, and for the support and application of the cloth thus pre- 

 pared a roller is applied, about 1 inch longer than the width of the doth, 

 having 6 or 8 bars fixed upon its periphery parallel to ils axis, and at equal 

 and such distances as will suit and act as detents against the transverse lim- 

 bers inside the cloih. This roller is supported by its gudgeons between two 

 strong pieces of timber built into and projecting from a wall. There is also 

 a frame of timber about 1 ft. G in. lonser ihan the intended length of the in- 

 clined table, composed of two sides fixed together by several cross bars of 

 timber, each about 1 inch longer than the width of the cloth, upon these 

 cross bars are fixed four or more lungiiudinal bearers, upon which the trans- 

 terse pieces of limber fixed to the inner surface of the clolh bear and slide 

 when the frame is at w ork, and at the lower end of this frame is fixed another 

 roller wilbout detents, of the same length and parallel to the head roller, its 



upper surface is in the same plane with the upper sides of the longitudinal 

 bearers. The upper end of this frame is supported by and between the head- 

 stocks, and tlie lower end suspended by a screwed rod on each side to a fixed 

 cr.5ss piece, by which the inclination of the table may be adjusted to suit the 

 nature of the maleri.ils to be operate 1 upon ; and at about one-third of the 

 length of the frame from the foot roller is fixed another roller to the lower 

 edge of the sides of the frame. Upon the frame and rollers the endless clolli 

 travels, passing from the head roller along the longiludinal bearers to the 

 loot roller, then over the under roller, between which and the head roller the 

 cloth hangs in a curve with its face downward, and low enough to reachabout 

 2 inches within a cistern filled with water wherein the ore is deposited as the 

 cloth revolves. At one quarter part of the length of the table downward is 

 fixed an inclined board with diverging channels to distribute upon Ihe whole 

 width of the tabic the stulV to be dressed liquified with water, whilst a stream 

 of clear « ater is made to flow uniloimly over the edge of a level board upon 

 the head or upper end of the table and the « hole of ils width. 



When to the apparatus thus described power is applied to turn the head 

 roller in the direction to move the cloth from the foot roller upward, and orey 

 water and clean water in jiroper quantities are permitted to flow upon the 

 table, it presents a moveable inclined table extending from the foot roller to 

 the head roller, upon which, by the action of the stream, the waste is sepa- 

 rated from the ores, which by their greater gravity resist the action or force 

 of the streams and adhering to the clolh are carried over the upper roller and 

 into the cistern, where the water disengages the ore and is there deposited. 



The claim is for dressing ores, or materials containing ores, upon an in- 

 clined plane continuously or occasionally moving up against the stream and 

 by the same motion depositing the dressed ores into a separate receptacle. 



The annexed diagram will show the motion of the cloth or flexible table. —

IMPROVEMENTS IN RAILWAYS. 



WiLU,Mii PROSSEK, Jun., of Shaftesbury-lerracc, Gent., for "Improvements 

 in Ihe construction of roads and in carriages to run thereon'" — Granted Nov. 9, 

 1844; Enrolled May y, 184,5. (Sec Engravings, Plate XVI.) 



The first part of these improvements relates to a mode of constructing rail- 

 ways with wood combined with guide rails for the purpose of guiding car- 

 riages thereon. The object of this part of the invention is to construct tram- 

 ways of wood, and by the application of a guide rail to dispense with flanges 

 upon the running and driving wheels of locomotives, which flanges, when 

 wood rails are employed, are considered very objectionable, indeed, almost 

 impracticable, in consequence of the flanges cutting up and thereby destroy- 

 ing the edges of the rail, therefore, in order to obviate these injurious eflects 

 the inventor employs a flanged pully fixed upon the middle of each axle of 

 the locomotive, as shown in the accompanying drawing, marked fig. 1, which 

 shows a transverse section of the rails having the improvement applied. .Si- 

 milar letters denote corresponding parts in buth figures : a a arc the wheels, 

 which in this case are made without flanges ; b is the axle, having a flanged 

 pulley, c, keyed upon it ; this pulley is made to embrace the guide rail d ; ec 

 are the rails, which the inventor prefers to make with the grain of the wood 

 in a vertical direction, which will render the rails more durable. The second 

 part of these improvements relates to certain modes of applying apparatus to 

 carriages moving on tram-ways of wood, in order to guide carriages thereon. 

 l''ig. 2 shows an end view of a locomotive engine having this apparatus ap- 

 plied, w hich consists of a frame-work/. r supporting two grooved pullies, g g, 

 turning upon axis supported by the frame-work at an angle of about 45°, it 

 will be observed that guide wheels of the above consiruction placed at each 

 end of ihe locomotive not only serve to keep the wheels upon the rails, but 

 will also lend to support the engine should one of the axles break or give way.
