Apfaratus to take up a Cauriage or Carriages whilst the 



TRAIN IS at full SPEED. 

 Fig 3, SiJu View. 



Fig. 4, Front View. 



A maoliine or apparatus by which a carriage may be taken up and 

 attached to a train, without stopping the train. Figure 3 is a side 

 view and section, and figure 4 a front view. A, is the fore wheel of 

 the carriage to be taken up, and .r the axle ; upon the axle is placed 

 the sheave F, within which coils the rope C, the sheave runs loo.«e 

 upon the axle, and is thrown in and out of gear with it by the clutch D, 

 worked by the lever e, the end of the rope is made fast to the sheave, 

 and the rope coils over itself, the ro])e may be of any convenient 

 length, about lOU yards I consider sufiicient. B, B, are two supports 

 depending from the framing of the carriage to support the axle more 

 steadily. L, is tlie framing of the last carriage of the train, to the 

 side of the framing is fixed the hook K, a post h, is placed at a proper 

 distance, upon which is fixed the hook or bolt /, the ring g, fastened 

 to the end of the rope c', is then hooked upon the bolt /; the hook k, 

 of the passing carriage hooks into the ring and carries away the rope, 

 which then drags the carriage to which the pulley is attached along 

 with it; but the carriage is dragged after the train by a velocity so 

 much slower than the train, as is due to the quantity of rope uncoiled 

 for every revolution of the wheel A, for example, if the train passed 

 over five yards, and the rope uncoiled four yards, the space passed 

 over by the carriage at starting would be one yard or one-fifth the 

 velocity of the train, but the velocity of the carriage is increasing as 

 the coil of rope becomes less, and it moves slower than the train until 

 all the rope is unwound, then afterwards the rope winds upon the 

 axle, when the carriage then moves at a greater velocity than the train, 

 and in the same proportion as the rope coils up wlien it at last over- 

 takes the train, then when it has arrived close u]i to the last carriage, 

 a bolt is fixed into the drag link, and the clutch is thrown out of gear, 

 and the carriage is then united to the triiiu the same as the rest, hi 

 this instance the sheave and apparatus is applied to the carriage, but 

 it may likewise be applied to the engine or tender, and the best place 

 to fix it would be outside the wheels, lengthening the shaft, and hang- 

 ing the sheave upon it ; and as regards the operation of taking on the 

 coach, the link or ring t, of the rope will liook into the hook K, in- 

 stead of the ring into the liook as before described ; and the rope C 

 will coil round the reverse way to that shown in the drawing, the 

 carriage is of course placed in a siding, and it enters the line by a 

 switch in the usual way. 



An improvehd Machinery or Apparatus for making Signals. 



Figure 5 



Tlie peculiarity of which consists 

 in conveying the signal a mile or 

 any convenient distance from the 

 station, the object being that the 

 engineer may pass the signal post, 

 and have distance and time suffi- 

 cient to stop the train before reach- 

 ing the station or place for stop- 

 ping ; the machine for a light is 

 shown in figure 5. A, is a lamp 

 post. C, a lantern of any peculiar 

 shape, with biU's-eyes on three 

 sides, or it may be formed of glass 

 like a street-lamii, or in any other 

 manner. C, is the lamp with re- 

 flectors behind the light in the usual 

 way. B, is a shade supported upon 

 the" vertical rod e, passing through 

 the post and united by a joint at 

 its lower end, with the bell-crank 

 F, to which is likewise suspended 

 the ball or weight M, to the other 

 end of the crank F, a joint is at- 

 tached, with which is connected a 

 strong wire g, which is led like a 

 bell-wire, by proper connections to 

 the crab h, placed in a room of, or 

 near, the station-house ; the wire, 

 or a chain or ro]ie united to its end 

 is fastened to the barrel (', of the 

 crab /;, which coils round the 



barrel — then when a man turns round the handle k, by means of the 

 pinion fixed on the handle shaft, and the barrel wheel denoted by the 

 circle n ; the barrel / is turned round, and the chain, or rope, or wire 

 is coiled round the barrel, the wire drawn in, and the crank F made to 

 occupy the place shown by the dotted line, when the vertical rod e, 

 and shade B are raised, and the light concealed, the counterbalance M 

 is employed to keep the connecting wire g always stretched ; in places 

 where gas is employed, a large gas burner may be substituted for the 

 lamp, and the rod (, made to communicate with a stop cock, so that 

 by raising or depressing the rod the gas may be turned on or off, then 

 a small concealed jet of gas may be always burning so as to inflame 

 the larger jet when the rod is raised by the apparatus, thus a powerful 

 light may be used when needed, and when not required the gas mny 

 not l)e wasted. The apparatus as drawn is a night signal, or to be 

 used when the weather is so dark that other signals cannot be seen ; 

 but for a day signal it is merely necessary to employ a post, so as to 

 raise a vane or vanes like a telegraph, a spar for example fixed at the 

 top of the lantern; when it is required to use the telegraph, a man 

 may make the necessary 'and self-evident connexion between the rod 

 f, and the limb of the telegraph, which limb being made with a bell- 

 crank, when the rod e is raised may cause the telegraph limb to lie
