SPECIFICATION forming part of Letters Patent No. 470,589, dated March 8, 1892. Application filed September 2, 1891- Serial No. 404,528- (No model.)

To all whom it may concern:

Be it known that I, MAURICE MITCHELL NEAMES, of St. Patricks, in the parish of St. James and State of Louisiana, have invented a new and useful Improvement in Inclined Railways and Cars Therefor, of which the following is a full, clear, and exact description.

Myinvention relates to an improvement in inclined railways and cars therefor, and has for its obj ect to provide a means whereby cars may be drawn up an inclined railway to a predetermined point, and when said point is reached whereby the carwill be automatically dumped, and when the load has been dis charged will be automatically placed in a position to travel down the incline of its own accord.

Afurther object of the invention is to provide a track and car of simple, durable, and economic construction, and also to provide a means whereby the car may be expeditiously and conveniently loaded and its contents rapidly and readily delivered into any vessel or receptacle adapted to convey said contents to a near-by or to a distant point.

The invention consists in the novel construetion and combinations of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the Views.

Figurel is a plan view of the inclined track or railway and a car represented as descending the same. Fig. 2 is a rear elevation of the railway. Fig.3 is a centralvertical section through the railway, a car being illustrated as descending the inclined plane, the said section being taken on the lineman of Fig. 1; and Fig. 4 is a vertical section through the rear or dumping portion of the railway, the car being illustrated in its dumping position.

The rails 10 of the inclined track A are supported by suitable uprights 11, located at predetermined intervals apart, which uprights maybe secured at their lower ends in the ground or upon a base frame or structure B. The latter is preferably employed, as illustrated. The base-frame extends some distance beyond the rear or upper ends of the rails 10, and from the upper end of each rail a beam 12 is projected rearward and downward, the lower ends of said beams being rigidly secured to the upper ends of posts 13, which posts at their lower extremities are firmly attached to the base-frame. The beams 12 are provided with recesses 14, produeedin their upper faces at theirinner edges, as best shown in Fig. 2, and at the lower end of each beam the recess extends from side to side.

A movable rail 15 is pivotally connected with each stationary rail 10 at the rear upper ends thereof, the said movable rails 15 being adapted at times to rest upon the recessed surfaces of the beams 12, and the movable rails are connected near their rear ends, preferably, by a cross bar 16, which cross bar, when the rail rests upon the recessed surfaces of the beams, has a bearing upon the lower extremities of the beams, the cross-bar being of suliicient length to extend some distance beyond the sides of the beams, as best shown in Fig. 1. i

A frame D is erected around the movable rails 15, the said frame consisting,preferably,

of. two uprights 17, united at their upper ends by a cross-bar 18. The uprights 17 are located some distance beyond the sides of the movable rails. Consequently the width of the frame D is much greater than that of the track, and when a base-frame B is employed the lower ends of the uprights are connected by a sill 19, which sill is located upon and secured to the said base-frame, as shown in 'Figs. 2 and 3.

The movable rails 15 are normally held at I such an elevation that they form a continuation of the inclined plane of the fixed rails, as shown in Fig. 8, which result is accomplished by means of weights 20, two being preferably employed, which weights have cables or chains 21 secured thereto, passed over suitable pulley blocks or sheaves 22, suspended from the cross-bar 18 of the vertical frame D, and the said cables or chains after passing over the pulleys are secured one to each extremity of the cross-bar 16, connecting the movable rails, as best shown in Fig. 2.

The car E consists of a body 23, mounted upon two axles 24c and 25, the forward axle being providedwith small wheels 26 and the rear axle with larger wheels 27 whereby when the car is ascending or descending the rails of the inclined track the body of the car is maintained in a horizontal position. Two hook-like or curved arms 27 are secured to the under face of the car, preferably in front of the pedestal in which the rear axle is journaled. These curved or hook-like arms are adapted for engagement with a bar or fixed shaft 28, located between the fixed rails at their upper ends and immediately in' front of the forward ends of the movable rails. The car is drawn up the inclined track through the medium of a cable 29, attached in any suitable or approved manner to the car and passed over the shaft 28, which may be provided with friction-rollers to receive it and over a pulley-block 30, preferably connected with a crossbar, connecting the uprights 13 at the rear portion of the fixed structure, as shown in Figs. 2 and 3,the cable being passed from the block to any convenient point, at which may be stationed a Windlass or any other form of winding mechanism.

The lower end of the inclined fixed track is adapted to be sunk below the level of the surrounding ground a sufficient distance to enable the car or other vehicle carrying a load to dump the same upon the body of the car E when said car is at the lower end of the track, at which point it receives its load.

After the car has received its load by means of the cable 29 it is drawn up the inclined fixed track until its front wheels have passed a sufficient distance over upon the movable rails of the auxiliary track and the curved arms 27 have engaged with the fixed shaft 28. As the burden of the weight is now upon the movable rails, the latter have moved downward, as shown in Fig. 4:, until they rest upon the beams 12. The'car-body will at that time have assumed such an inclination as to discharge its load completely and quickly into any receptacle placed at the rear of the auxiliary track, and the moment the car E is relieved of its load the weights 20 act immediately to elevate the movable rails, and when 1 the cable 29 is slackened the car will automatically travel downward to the point from which it started.

It will be observed that the car and the and that they cannot fail to act in the manner described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a fixed inclined track and an auxiliary track pivoted at its inner end in line with the fixed track and provided with means for raising its free end, of a car and a stop mechanism to stop the car at the upper end of the fixed track when its forward end depresses the pivoted track, substantially as set forth.

2. The combination, with a fixed inclined track and an auxiliary track pivoted at its inner end'in line with the fixed track and provided with means for raising its free end, of a car having front and rear wheels and a stop mechanism to stop the car and cause it to dump when its front wheels depress the pivoted track-section, substantially as set forth.

3. The combination, with a fixed inclined track, a pivoted track-section at the upper end thereof, and means for raising the upper free end of said pivoted section, of a car hav-' ing small front and larger rear wheels, and a stop mechanism to stop the car and permit it to dump when its smaller wheels pass upon the pivoted track-section, the said stop mechanism comprising a hook-like arm depending from the car adjacent to its rear wheels to engage a part of the track structure at the upper end of its fixed portion, substantially as set forth.

4. The combination, with a fixed inclined track, an auxiliary track having a pivotal connection with the fixed track, a shaft secured in the fixed track near the auxiliary track, an inclined bed located beneath the auxiliary track and adapted to receive the same when depressed, and weights connected with the free end of the auxiliary track, of a car having its forward Wheels smaller than the rear wheels and provided with arms adapted for engagement with a fixed shaft, and a draft mechanism connected with the car, as and for the purpose specified.

MAURICE MITCHELL NEAMES.
