The invention* is described as consisting in " certain mechanical 

 contrivances and arrangements, by means of which common railway 

 trains running upon railways of the ordinary construction, may be 

 always brought to a stand without the agency and independently of the 

 will of the engine-driver, guard, or other person or persons thereon, or 

 travelling therewith, and at any given distance from a station or at 

 any part of a line where it may be deemed advisable to have such in- 

 dependent means of stoppage provided." 



The "mechanical contrivances and arrangements" divide them- 

 selves into two branches, the first including tliose which relate to the 

 engines and carriages, and the second those which relate to the road- 

 way. 



I. The additions proposed to be made to locomotive engines for 

 carrying this plan into effect are represented in the accompanying en- 

 gravings, figs. J, 2, 3, and 4. 



Fig. 1 is an end elevation of a locomotive engine with the apparatus 

 attached, and fig. 2 is side view thereof; fig. 3 is a plan of one of the 

 rails and apparatus attached on the ground, fig. 4 is a side view thereof. 

 A is the handle of the steam regulator, and B is the handle of the 

 steam whistle. These handles are each fitted with loose collars, but 

 so as not to interfere with the common mode of using them by hand ; 

 each collar has a projection to which the ends of the chains D and E 

 are attached respectively, F is a horizontal lever fixed upon the spindle 

 G, carrying the pins a and b, and to the two loose collars on these, the 

 other ends of the chams are connected in like manner. The vertical 

 spindle G is secured near the top by the bearing c fixed on the pro- 

 jecting rail ; from this it descends through the eye d, attached to the 

 guide plate of the axle on which it is supported by a collar, and H is 

 a crank lever fixed on the lower extremity. 



"When the engine is running, and the whistle shut, the several 

 parts described are in the exact position shown in the drawing, viz. both 



" The patent is in the name of Mr. Petti t, but Mr. Hancock and Mr. Pettit 

 are joint proprietors of the patent riijht.
