T0 all 7,071,071@ it 77u01/ concern:

Be it known that I, JAMES MCGANN, a citizen of the United States, residing at Tyndinere, in the county of Richland and State of North Dakota, have invented a new and useful Freight and Baggage Loader, of which the following is a specification.

The principal object of the present invention is to facilitate the handling of trunks, baggage, and freight and to provide a mechanism of simple and economical construction which may be attached to existing freight and baggage cars for rapidly loading' and unloading said cars.

A further object of the invention is to provide a device of this character which may be operated by the compressed air from the trainpipe of the brake system and to provide means whereby the station agent or other employee standing at. one-side of the car may control the operation of the device through the manipulation of a suitable valve or valves.

A still further object of the invention is to provide an apparatus of this character which may be placed on both sides of the car and disconnected from the operating means when not in use, the apparatus at the loading side of the car being adjusted to operative position, while the mechanism at the opposite side of the car remains inoperative.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel feature-s of construction and arrangement of parts hereinafter-fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being Linderstood that various changes in the form, proportions, size, and minor details of the structure may be made without departing' from the spirit or sacrificing' any of the advantages of the invention.

In the accompanying drawings, Figurel is a vertical section of a portion of a baggagecar provided with a baggage or freight handlingI device constructed in accordance with the invention. Fig. 2 is an inverted plan view of the mechanism. Fig. 8 is a detail sectional view of one form of controllingvalve which may be employed.

Similar characters of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

rl`he car A is of any ordinary construction and is shown in the present instance as provided with doorways on -opposite sides. At

rthe member 22 by means of a link 29.

a point below and near each side of the car is arranged a pair of hangers 10, having bearings for the reception of a shaft 11, to which is secured a pair of rocker-arms 12, the outer ends of said arms being' connected by cross bars or plates 13, forming a platform on Which the trunks or other articles to be loaded or unloaded may be placed. To one of the arms 12 is connected one end of a-chain 14, a link of which may be passed over a suitable hook 15, projecting from the side of the car in 0rder to support the apparatus in elevated or inoperative position when not in use, as shown to the right of Fig'. 1, or the platform may be held in mid-position, as shown in dotted lines to the left of Fig. 1, in order to form a step to facilitate the loading and unloading of baggage where it is not necessary to use power. During operation, however, the platform moves from the lowest position (shown to the left of Fig. l) to an elevated position, similar to that shown to the right of Fig. 1, and heavy baggage or freight maybe raised from the station-platform to the car or may be lowered from the car to the platform Without danger of injury to the trunks or other articles.

Secured to the bottom of the car in any suitable manner, as by hangers 17, is a cylinder 18, in which is arranged a piston 19, normally held in the dotted-line position shown in Fig. 2 by means of a spring 20. To this piston i's connected a rod 21, the outer end of which is connected to a lever 22, that is pivoted at a point about midway of its length t0 a supporting-bracket 24, depending from the carframe.

The rocker-arms l2 of eachof the loading devices are formed integral with or secured to depending rocker-arms 26, connected' at their lower ends by a cross-bar 27, with which may engage the forked end of a rod 28, the opposite end of said rod being connected to Each rod 28 is supported near its outer end by a loop or guide 30, depending from the carframe and so arranged as to permit slight vertical play of the rod when in operation. Each rod 27 is provided with an enlarged flange or disk 82 in order to prevent accidental displacement of the forked end of the rod 28 while the apparatus is in use.

The device forming the subject of the present invention is intended to be operated by a iiuid under pressure, and preferably this iiuid is supplied from the train-pipe B, said pipe IOO IIo

' n`akframe pivoted under the car, and a framebeing shown as provided with a connection 34, leading to the cylinder 18. ln this connection 3a is a valve-casing 35, containing a valve 36, that is provided with two

ports

37 and 38, and in the valve-casing' is an exhaustport 39. To the lower end of the valve is secured a two-armed lever 40, the opposite ends or arms of said lever being connected to rods 4-1, leading to opposite sides of the car and provided with suitable operating-handles et?, that are arranged within convenient reach of the station agent or other person operating the device.

Vhile the train is running, both of the platform members are held in elevated position, as shown to the right of Fig. 1, and are disconnected from the operating mechanism, When the train arrives at the station, the elevating device at the platform side is unhooked and lowered and the bar ZT enters the forked end of the rod 28, while the apparatus at the opposite side of the car remains inoperative. A trunk or other article is then placed on the platform, and the operator pulls on the handle 42, allowing air to flow from the train-pipe, through the connection 34, to the cylinder 18. The piston 19 is moved outward and movement is imparted to the rod 2S, thus elevating the pivoted platform and moving the trunk or other article up toa position above the level of the car-floor, from whence it may fall over into the carin a position to be removed by the baggage-master. ln lowering a heavy article the operation is reversed, the valveoperating rod LL1 being moved slowly in order to allow the air to gradually exhaust from the cylinder through port 39.

1n some cases, especiallyv where the baggage or freight is comparatively light, the platform n'iay be hooked in a mid-position, as i shown in dotted lines to the left of Fig. 1, and used as a step or platform to facilitate the manual lowering and raising' of the baggage.

Having thus described the invention, what is claimed is- 1. 1n apparatus of the class described, a car,

operating' means normally disconnected therefrom.

2. In apparatus of the class described, a car, a hoisting-frame arranged at one side of the car, and a fluid-pressure operating means normally disconnected from said frame.

3. In apparatus of the class described, a car, a hoisting-frame arranged at one side of the car, a fluid-pressure cylinder having a valved 1 connection with the train-pipe, a piston ar- 1 ranged within the cylinder, a piston-rod, and detachable connections between the pistonrod and frame to permit movement of the latter to 'inoperative position.

4. In apparatus of the class described, a car, a pair of hoisting-frames arranged atopposite sides of the car, a fluid-pressure cylinder, a piston arranged within the cylinder, operating members extending from the piston toward the sides of the car, and means vfor adjusting one or other of said frames into operative position.

5. The combination with a car, of a pair of hoisting-'frames arranged on opposite sides of the car, an operating mechanism common to both frames, said frames being normally detached vfrom the operatingmechanism and bein g independently adjustable into operable relation therewith.

6. In apparatus of the class described, a car, a pair of hoisting-frames arranged on opposite sides of the car, a fluid-pressure cylinder having a valved connection with a source of fluidpressure supply, a piston arranged in the cylinder, means 'for connecting the piston to the frames, and if'alve-operating rods extending from the valve to points adjacent to the sides of the car.

7. ln apparatus of the class described, a car, a pivotaily-mounted frame arranged under the car, a rocker-arm carried by the frame and provided with a projecting pin or stud, a Vfluid-pressure cylinder under the car, a piston arranged in said cylinder, a piston-rod, and a 'forked rod having' an operative connection with the piston-rod, the pin or stud being adjustable to permit connection with or disconnection vfrom said forked rod.

8. 1n apparatus of the class described, the combination with a car, of a pair of frames arranged at opposite sides of the car, rockerarms carried by the `frames and provided with headed pins or studs, a fluid-pressure cylinder arranged under the ca r, a piston in said cylinder,' a lever to which said piston is connect-A ed, a pair of forked rods extending from the lever and adapted to engage said headed pins or studs, and a pair of valve-operating rods extending from the valve tothe opposite sides of the car.
