Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed .lctober 30. 1906. Serial No. 341.328.

To all whom it may concern:

Be it known that I, ANDREW Monnocrr, of the city of Ottawa, county of Carleton,

Province of Ontario, Dominion of Canada,

have invented certain new and useful Improvements in Stock-Oars, of which the following is a specification.

My invention relates to improvements in stock cars, and the objects of my invention for raising and lowering the floor, a furtherv object being to provide means for quickly filling and emptying the car and it consists essentially of the improved construction herein after set forth in the accompanying specifications and drawings and specifically mentioned in the claims.

In the drawings :Figure 1 is a longitude same. Fig. 5 is a perspective detail of the I clasp for locking the ,iioor in position. Fig. 6 is a perspective detail of the catch for the slidable doors. Fig; 7 is a perspective detail of the rollerssecured to the sides of the floor. Fig.8 is a sectional detail of the connection between the slidable door and the slide therefor. Fig. 9 is an enlarged sectional detail of the clasp at the top of the car. Fig. 10 is an enlarged sectional detail showing the clasps at the bottom of the car and the supporting flange for the floor. Fig. 11 is a detail view showing a manner of connecting the rising and falling floor with the operating mechanism.

In the drawings like figures of reference indicate corresponding parts in each figure.

Referring to the drawings, A is the carbody supported as usual from the trucks cl, 6, and comprising an upper and lower deck a, and I) united by side and end walls 0, which as shown are formed by consecutively placed round stanchions 23 preferably formed of metal.

B is the vertically movable floor or platform located within the car body and having rollers f journaled in bearings g secured to the sides thereof. The rollers f are adapted to abut the standards and thus reduce the friction in raising and lowering the floor. They are omitted opposite the doors as shown.

The floor, in the embodiment illustrated, is raised and lowered by a plurality of hoisting devicesO, each comprising two vertically extending racks 7b which are suitably secured at their upper extremities to the floor B, as

by angle-irons b (Fig. 11) agear supported from a frame 12 and connected to the racks by connecting gears 7r. which will cause them both to move in the same direction, and a plate or disk Z secured to the driving gear and having an outwardly extending flange 13 secured to or formed integral with the periph ery thereof, in which are a plurality of apertures m through which the hands of the man operating the device may be inserted. These large disks enable a very considerable purchase to be obtained whereby each device may be operated by one man.

To relieve the strain on the gears I provide spring-held dogs a and 0 which engage teeth 9 and (1 provided respectively on the side and front of each rack. By this means the floor is automatically locked in each adjusted position and the strain removed from the gears. The two dogs operating on each rack give an increased degree of security. The racks are held intheir proper place by slides r and s which are encircled by straps zand a secured to the racks.

To look the floor in its raised or lowered position I provide a plurality of two-part clasps o, one part of which is fixedly secured to the stanchions 23, and the other part of which is hinged to the first part and has apertures w therein through which are adapted to extend, the ends of outwardly protruding lugs :10, secured to the movable floor, the

ends of the lugs having holes therein through which locking pins y may be inserted. These clasps are secured tothe car body at the top and midway down, those midway down being supported by being hinged to blocks 11 (Fig. l) secured to the rods 23, and being inverted in position as shown in Fig. 5, whereby they will not be in the way of the lugs when the fioor is raised.

In operation when the floor is lowered to its lowest position, the upper part of the clasp '0 will be swung into its vertical position in which the lugs a: will extend through the aperture w and it is locked in this position by the insertion of the pins y. The lugs a: are preferably formed by the ends of bars 2 which and. 6, divided midway ,betweenthe bottom and top. Each of the parts 5 and 6 are supported with freedom to slide laterally on slides 7 and 8 which are encircled by straps 9 secured to the door. The slides 7 and 8 consist simply of two parallel rods secured at their ends by straps 22, to the stanchions 23. The straps 9 which are secured to the door as illustrated in Fig. 8, encircle these slides and permit a lateral sliding movement.

By this means, as shown in Fig. 1, any half door may be opened separately. To lock each of the half doors in a closed position catches 10 are provided as shown in Fig. 6. The object of having doors at opposite ends of the car is to provide for the speedy filling of the car by the employment of a trained animal which may be led in one door and out the other. To give additional support to the floor in its lowest position I provide a flange 11 secured -to the walls of the car and adapted to abut the underside of the floor in its lowest position. When the car is to be filled with large cattle such as bullooks, the floor is raised to the top and there locked in position by the clasps o, butwhen small animals such as sheep, goats, or pigs are to be loaded then the floor is lowered midway and the animals loaded thereon, thus doubling the capacity of the car.

It will thus be-seen that I have devised a car which can accommodate any size of cattle and into which the animals may be led with the greatest speed possible. It will also be readily understood that while I have described with particularity of detail one form of my invention, yet changes might be made therein within the scope of the appended claims without departing from the spirit of my invention.

What I claim as my invention is:

1. In a stock car the combination with a vertically movable floor of a plurality of out wardly protruding lugs thereon, and clasps secured to the car and adapted to engage said lugs.

2. In a stock car, the combination with a vertically movable floor, of a plurality of outwardly protruding lugs thereon, and clasps secured to the car at the top and midway down adaptedto engage said lugs and hold the floor in position. i

3. In a stock car, the combination with a vertically movable floor, of a plurality of outwardly protruding lugs thereon, clasps secured to the car at the top and midway down adapted to engage said lugs, and a flange eX tending around the inner wall of the car and adapted to abut the under side of the floor in its lower position.

4. In a stock car, the combination with a vertically movable floor, of a plurality of racks secured to the sides thereof, means for raising and lowering said racks, ratchet teeth on the front and side of each of said racks, and spring held dogs engaging said teeth.

5. In a stock car having a vertically movable floor, an improved hoisting means therefor comprising a number of pairs of racks secured to the sides of the fioor, driving gears for the same, connecting gears between the driving gears and the racks, plates secured to the driving gears, and-outwardly extending flanges on the peripheries of the plates having hand apertures therein.

6. An improved stock car comprising a car body having the walls thereof formed by consecutively placed. stanchions, a vertically movable floor within the same, a plurality of outwardly extending lugs secured thereto, clasps secured to the car body and. adapted to engage the lugs when the floor is in its raised and lowered. position, a' plurality of rollers supported from the floor and abutting the stanchions, a plurality of pairs of racks secured to the sides of the floor, operating gears therefor, ratchet teeth formed on the side and front of each rack, spring held dogs engaging the same, and two part doors at opposite ends of the car body opening above and below the floor in its lowest position.

Signed at the city of Ottawa this 24th day of October 1906.
