SPECIFICATION forming part of Letters Patent No. 528,407, dated October"30,v1894.

\ Application filed April 8, 1893. Serial No. 469,519. (No model.)

To all whom t may concern:

Be it known that I, ALBERT L. WIDDIS, a citizen of the United' States, residing at Detroit, county of Wayne, State of Michigan, have invented a' certain new and useful Improvement in Electric Elevated-Railway Cars and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Thisy invention relates to elevated railway cars, and has for its object improvements in an elevated railway'car and the appurtenances belonging thereto,wh ich are especially designed to permit rapid transmission of parcels, especially mail parcels, across the country.

In carrying out this invention, I employ a track which is elevated, and properlygsupported on posts. T he track is a one rail track, and on it run the car wheels ot' a suspended carriage. The carriage is divided into compartments, one of which contains the motor,

and the others of which are suitably disposed to contain a number of mail bags or similar packages which are to be dropped at proper stations as the car travels across the country.

There are suitable attachments to cause the' mail bags or parcels to drop automatically. Other features of construction and novelty will be referred to hereinafter, and specified in the claims.

In the drawings, Figure l shows aside elevation of the car, the track and supporting posts. Fig. 2 shows a detail'of the means by which the bag or parcel is supported. Fig. 3 is a detail of the brake. Fig. 4 is a cross section on an enlarged scale through the middle of the car shown in Fig. 1. Fig. 5 is a plan of the car some of themiddle parts being broken away. Fig. 6 shows a `shifting device connected with the-automatic dropping apparatus. Fig. 7 is a plan of the bar of the same shift-ing device. Fig. 8 shows in detail, on an enlarged scale, the arm by means' of which the unloading of parcels is effected.

A indicates the track rail, which is supported at suitable intervals by arms D that extend out from a main supporting post T. TheY arms D also support a guard rail ct, which port the car B.

is beneath the main rail and at one side thereof. l

n W W indicates the running Wheels of the car, and of these running wheels there are preferably four grooved wheels, the two middle wheels being arranged as drivers and connected with the motor mechanism. These wheels are journaled in hangers E, which sup- The hangers E also carry guard wheels w, 'and these guard wheels w are normally carried below and just out of contact with the guard rail a, being so arranged that any swaying motion'ot the car body brings the guard wheel w and the guard railc into contact.

In the middle of the car B isacompartment b, in which is located a suitable motor, preferably an electric motor, which receives its force from the line wire C through a trolley c and a trolley pole c. On each end of the axle of the motor is a set of governor balls G, and one of lthese governors actuates va lever g, which', in turn, throws a switch arm g across the contact pieces g2 of a rheostat, and thus acts to increase or diminish the amount of electric energy admitted to the coils surrounding the various parts of the motor.

In front and at the rear of the carriage are compartments dividedintoV sections, and in each section is a receptacle for the load to be carried. Thereceptacle is preferably in the shape of a bag having a square or rectangular mouth opening, around which is an inclosing ring 6, by which it is held suspended, in the frame work of its section.` On opposite sides of the inclosing ring are two lugs h h, and on the side of the framework of the compartment in which the bag is received is a swinging stirrup h. When the stirrup h is vertical and the bag Z1. is' dropped into its compartment, one of the lugs h will rest in the bottom of the stirrup h; but, when the bottom of the stirrup h is. pushed outward away from the bag, the bag Hkwill drop and the releasing devicefwhich produces this movement is as follows:

On the top of the car is a bar IJ held under straps c' and i', and capable of movement endwise under the straps for a Vshort distance. On each end of the bar I`is a sprocket wheel J J', and, rising from the top of the carv on posts which are in line with the axis of the bar I, are two sprocket wheels jj. Each of the sprocket wheels just described has connected with it a pinion. The pinions belonging to the sprocketwheel J can be brought into engagement with the pinion connected with the sprocket wheel j; and, by shifting the bar, the two pinions last mentioned can be thrown out of engagement, as is indicated in Fig. 6 and the pinion connected with the sprocket wheel J can be brought into engagement with the pinion connected with the sprocket wheel j. However, only one set of pinions can engage at a time. Vhen the bar is shifted in one direction, the pinion at the end of the bar engages with the pinion on the post that is nearest to it. The pinion at the other end of the bar has been moved away from the pinion on the post at that end, and those two pinions are out of engagement.

The wheels J and J are belted by a sprocket chain J 2, which passes around a third sprocket wheel J 3, on the upper side of which are ratchet teeth J 4. On the shaft ofthe sprocket wheel J3 is a ratchet arm J 5, towhich is connected a pawl J 6, which engages with the ratchet teeth J4. To the frame-work, near the wheel J 3, is hinged a pawl J7, over which the ratchet arm J 5 reciprocates. The pawl J 7 is provided on either side with an oblique guide J 8, and terminates at its engaging end with the pin J9, adapted to engage with any one of the several holes in the wheel J 3. The sprocket wheels j, j each aetuate endless chains j2,j3. There is one of these chains at each end of the car. The chain L7'2 is arranged to engage with all the receptacles in the several compartments at the end of the car on which it is located, and has upon it a lugj4 which will successively release each of the receptacles from its compartments by engaging with and pushing the end of the stirrup h out of engagement with the lug h. When all of the bags at one end of the car have been released, the bar I is automatically shifted; the pinions of the sprocket wheels j and J are brought into engagement, and the bags at the second end of the car dropped successively. The chain 3'2 is actuated by its sprocket wheelj'. This in turn receives its motion from the inter-meshing pinions, one of which is on the same shaft with the sprocket wheelj, and the other of which is on the same shaft with the sprocket wheel J The wheel J and the pinion connected with it are actuated by the chain J2 which receives its motion from the wheel J 3, and this is actuated intermittently by the ratchet arm J 5. The ratchet arm J 5 is actu ated in one direction by the opposing force of a fixed object located beside the track, which engages with the end of the ratchet arm J5 and holds it while the car moves forward, the holding engagement continuing until the arm has swung backward and inward far enough to pass the obstacle.

The shifting of the bar I is caused by mechanism which is shown in Figs. 6 and 7. The

end ofthe bar I extends beyond the shaft of the sprocket wheelj, and engages with a catch k. The catch 7c rocks on the same shaft as the stirrup h', and when the stirrup h is swung to release the last one of the bags from its section, the catch 7c rocks with it and is disengaged from the bar I, and the bar I is :immediately shifted endwise through the resilient force of a spring 7 which had been held in a state of tension by the interlocking ofthe bar and catch 7c.

The car is propelled by the driving wheel W on the motor, around which passes an endless belt that leads over the small driving pulleys w on the axles of the two middle wheels NV.

The front and rear end of the car are preferably coned or pyramidal in shape, and on each side of the body of the car is a wing These wings are arranged to be adj usted so that their angle or Obliquity to the plane of the track may be regulated at will, the object being to produce an air pressure either up or down, as may be desired, to regulate the traction weight of the car on the rails.

The brake which I employ is shown in detail in Fig. 3, and in elevation in Fig. 4L. A side elevation is also seen in Fig. l. The brake is arranged to be automatically thrown into engagement with the wheels W as the car approaches a station at which it is to stop. S indicates a side bar connecting the axles ot the wheels, and to this side bar the brakes S are secured by pins s, and the brakes are connected bya reach rod r. The reach rod r is reciprocated by means of a bell crank lever R, a link fr', a rock shaft R', rock arms R2, R3, and lever R4. The free end of the lever R4 extends horizontally out at the side of the car, and engages with an obstruction placed near the track and at the proper place. The inner end of the lever Rl engages with the rock arm R8 by means of a sliding joint. The toothed rack rzholds the arm of the lever R4 after it has been pushed backward by the obstacle against which it strikes.

The track employed by me is a double track, one track being used for cars going in one direction, and a second track being used by cars going in the opposite direction.
