Specification of Letters Patent. Pgmygntd Edgy 9,1922.

Application filed December 20, 1920. seriarm; 4s2,o5o.- i

To all w 710m it may concern Be it known that I, LEONIDAS S. HUDsoN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey have invented a new and useful Overhead Carrier, ofwhich the following. is aspecification. I v

This invention relates to a knockdown structure for use as a track for a traveling conveyor, one of its objects being" to provide atrack-of novel construction made up of units which can'be adjusted angu'larly relative to eachother,,thereby to guide a conveyor to any desired point or points.

A further object is to provide a' structure of this character which is strong anddura- Me and can be set upand taken down easily.

Another object is to provide a structure especially suited for use in concrete construction'work; it being possible to employ itin the operation of an overhead conveyor provided for carrying "thematerials to a 111lX8I',-:1I1(l also to use it for conveying the mixture from the mixer or from a hoist, to the points of-use. j

W'ith, the foregoing and other objects in view which will appear as the description proceeds the invention consists of "certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims it being understood that various changes may be made in the construction and arrangement of the parts without departing from the Spirit or sacrificingany of the advantages of the invention as set forth in the accompanyine claims.

In the drawings the preferred form of the invention has been shown.

Tn said drawings- F'igure 1 is a side elevation of the structure. parts being broken away.

Figure 2 is an enlarged transverse section therethroughl Figure 3 is a plan view of a portion of the track and its supports.

Figure 4 is a longitudinal section through a portion of the track. 7

Figure 5 is a plan view of one of the track joints.

Figure 6 is a detail view partly in section of portions of one of the supports and one of the braces. 1

Referring to the figures by characters of reference. 1 designates supporting legs or standards arranged in pairs and provided at theirupper ends with extensions 2 a't' the bases of which are provided inwardly-extending shoulders 3. These'sta'ndards are oppositely disposed, the standards of each pair converging upwardly and being connect-eda't their upper ends by cross'braces 4 in the form of strips having openings 5 into which the extensions 2 project. connected to'the lower portion of one standthereinto from its lower edge adapted to rethe other standard of said pair. 7

Pivotally ardof each'pair-is a-lower brace 6 the free end portion of which hasa slot 7 extending ceive a stu'd'or projection" 8 entending from I ITwo pairs of standards are provided for each unit of thestructure and resting'on the shoulders 3 of thestan'dard's are angle rails 9 the upstanding outer side flanges of which are deta'chably secured to the extensions 2 by bolts 10, as shown. Thestandards are connected to the rails near the ends of the rails and the parts are preferably reinforced by braces 11. diagonally-arranged "between the st-ar'ijdards and th'e rails as shown.

Each

brace is, detachably connected" atone end; as by hook' 12 and eye or loop 13 sothat when the structure. is knockedjdown the parts can be folded reai'dily- I One end of each rail 9-has an car 14 eX- tending therefrom flush with the topsurface of the rail base while a recess 15 is formed under the ear; The otherend of each rail has an car 16 extending from the bottom sur face of the rail and provided with a recess 1.7 thereabove. The ears are provided with openings 18 so that when the units of the structure are assembledthe ears 1401 one unit will lap the ears 16 of the next unit and couplingbolts or pins 19 can be inserted into the registering openings 18 and held by cotter pins or the like. With the units thus assembled they can be adjusted angularly to extend the track in any desired direction.

Obviously any desired number of units can be assembled. The end units of the structure will be provided at their free ends with cross strips 20 and 21 respectively. The i strip 21 is provided at the center with a.

sheave 22 while the strip 20 is provided at V the center with sheaves 23 and 24:.

A carriage 25 of any desired construction I I is mounted to travel on the rails andis held against lateral displacement by the upstanding flanges of the rails and ,between which the wheels of the carriage travel. See figure 2. This carriage a conveyor bucket 26 suspended therefrom and the bucket can be of any construction desired. A cable 27 is connected to one end of the carriage and eX- tends over the sheave 22 and thence back the full length of the structure to the sheave 23 and to a drum 28 driven by an engine, not shown. Another cable 29 is wound on the drum 28 in the opposite direction and extends over the pulley 2% to the other end of the carriage. Thus the carriage can be operated toward or from a chute 30 used for directing materials into the bucket 26.

It is to be understood that the structure ran be carried from place to place in a knocked down condition and the parts can be set up readily either on the ground for the purpose of conveying materials to a concrete mixer or on a floor of a building under construction where it can be used for conveying the mixture from a hoist to different places where the mixture is to be spread or deposited. With this arrangement it becomes unnecessary to use a number of wheel barrows as heretofore and, consequently, the runways that have been necessary, the large number of employees, etc, can be dispensed with. As a result the cost of the construction work can be greatly reduced and the work can be materially expedited. The structure can also be used to advantage in road building, as will be apparent.

That is claimed is 1. A structure of the class described including a series of units each including supports arranged in pairs, upwardly projecting extensions upon the supports, opposed rails bearing on the supports and secured tothe extensions, said rails having upwardly extending guide flanges, cross braces detachably engaging the extensions, braces detachably connecting the lower portions of the supports, and means for detachably and pivotally connecting the ends of the rails of abutting units.

2. A structure of the class described including a plurality of units each including angle rails, a pair of supports detachably connected to the rails at each end, extensions upon the upper ends of the supports, cross braces engaging and removable from the extensions, cross braces connecting the lower portions of the supports, ears projecting from the ends of the rails, the ears on the rails of each unit lapping the cars on the rails of the next adjoining units, means for detachably and pivotally connecting the lapping ears, a carriage movable along the rails, and cables extending longitudinally of the rails for shifting the carriage longitudinally of the rails in either direction.

3. A structure of the class described including a series of units each comprising pairs of supports, parallel rails mounted on the supports, extensions upon the supports and above the rails, braces above the rails and connecting the extensions, braces below the rails and connecting the supports, said braces, supports and rails being detachably connected, and detachable pivotal connections between the rails of adjoining sections.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

LEONIDAS S. HUDSOY.
