CONVEYER'; A

Application le. August 30, 1922. SerialNo, 585,232.

The gene-ral object of my invention is toy provide a conveyer characterized by simplicity, low cost, and` portability and by the use of which great economy of time and labor results as for example in the conveying of materials or articles from a. freight car to a house or to a pointmore or less distant'. with the minimum handling. i

Reference is to be had to the accompanying drawings forming 'a part of this specification7 it being understood that the drawings are merely illustrative of one example of the invention.

Figure l is a side elevation of a conveyer embodying my invention;

Figure 2 is a plan view thereof;

Figure 3 is an enlarged side elevation of a fragment 'of the conveyer; Y

Figure 4 is a cross section on the line 4 4, Figure 8;

Figure 5 is an elevation of the supporting structure and track at a joint where the conveyer is to be given considerable length.

in carrying out my invention in accordance with the illustrated example, an elongated supporting structure l0 is provided here shown as having legs ll, said structure consisting either of a plurality of beams placed end to 'end or of a single beam. @n a side of the supporting structure l() are brackets l2 flaring rearwardly from a central vertically disposed front i8 of each bracket, said vertical front having secured thereto by brazing, welding or any other suitable means, a track 14 consisting of flat metal disposed vertically and projecting at its upper and lower edges above and below the fronts 13 of the brackets l2. Said brackets l2 terminate in a vertical plane and are secured by any suitable fasteners l2a to the vertical side faces of the support l0.

l/Vhere a plurality of supporting beams lO are to be joined a cap plate l5 may be provided at the joint and overlapping the adjacent ends ofthe beams, saidplate-.befing secured by screws `16 or the like to the respective beams. At a joint also a bottom bearing bar 17 extends across the joint` and secured asr by bolts 18 to the structurel() at the adjacent ends of the beams. ends of adjacent rail sections 14 -at the joint are inter-engaged by a mortise and tenon as at 19. y

The track rails 14 are disposed -in pairs at the sides of each elongated support lO and below the same and travelling on the^respec 'tive tracks are carriages 20 made suitable in practice for carrying of 'any particular material, the carriages being'sho-wn as having plain flat tops in the present-example to receive a bag A containing cement for example. The structure lO is inc-lined, the legs li at one end being higher than the other so that the material is conveyed by gravity from the upper end to the lower end.

Secured to the carriage on the respective tracks is a rope or cable 30 running over pulleys 3l at the upper end of the structure. rlhe arrangement is such that a load, as for instance a bag A, placed' on the upper end of the conveyer willvtravel downwardly by its own gravity to the lower end thereby returning the empty carriage on the other track to the upper end so that the carriages are used alternately conveying the material from a freight car B to a cement house, for example, conventionally indicated at C.

The wheels 2l of the carriages are Wit-hin 5cl-shaped housings 22 arching over the Wheels at the top, the outer leg or side of each housing being the longer and continued below the rails 14. the lower edge 23 being turned laterally inward and upward beneath the adjacent track rail i4. The pin The butt or axle 24 of each Wheel 2l passes through scribed arrangement makes for flexibility' in the carriage and at the same time prevents` derailing thereof.

` l would state in. conclusion that while the' illustrated example constitutes a practical embodiment of my invention, I do not limit myself., strictlyy to the exact details herein illustrated, since, manifestly, the vsaine can be considerably varied Without departure` rorn the spirit-of thezinvengtion. as defined in the appended claims.

Having thus described my invention, in claim:

l. A. conveyer comprising-a pair ofsupporting bea-ins, brackets secured to the oppositeA vertical side faces oisaidlbeams, said brackets having.y approximately centra-l portions .disposedlaterally out-Ward of the beam, traclrv railson said central' portions of the brackets, the upper andi lower edges of the rails` extending respectively above and below the brackets, a carriage having Wheels travelling on` the track rails of each beam, housings in which said Wheels are journaled, and elementsv secured to the carriages and having depending hangers secured to said housings at theinner sides of the Wheels.

2,'A conveyer comprising a supporting structure having pairs of rails, a pair of carriages having-Wheels to run on said rails,

Memes and housings secured to the carriages. and orming bearings for the axles of thefwheels, said. housings at the outer sides extending below, the Wheels` and tracks and having their lower edges directed inwardly and upv-rardly beneath the rails.

3. A conveyer including ay supporting structure, pairsofi track rails thereon, a carriage for each pair of rails, carriage Wheels in pairs, housings,` archingloven said Wheels, and brackets on, theunder. side of the carriages hingodly,y secured to, said 1` housmgs@ 4. A conveyor including a supporting structnre, pairs of' track rails.. thereon, a carriage for each pair of rails, carriage nf'heels in pairs, housings arching over. said Wheels, and brackets on the under side of the carriages hingedly secured tosaid housings, the lower edges of said housings at the outer sides of the latter turnedinvvardly and upwardly beneathy the rails.
