SPECIFICATION forming part of Letters Patent No. 620,015, dated February 21, 1899.

Application filed August 31, 1898. Serial No. 689,905- mo model.)

To all whom it may concern:

Be it known that I, MICHAEL BUTLER, of Austin, in the county of Travis and State of Texas, have invented a new and Improved Freight-Oonveyer, of which the following is a full, clear, and exact description.

My invention relates to improvements in devices for transporting freight and packages of all kinds; and the invention comprises the novel features which will be hereinafter described and claimed.

Reference is to be had to the accom panyin g drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my device, parts being in section. Fig. 2 is an elevation at right angles to that shown in Fig. 1. Fig. 3 is an inverted plan view of the mechanism for giving lateral movement to the carrying-rods, and Fig. 4 is a sectional elevation taken through the supporting swivel or pivot.

The object of my invention is to provide a device which may be readily operated by a single man to handle freight or packages of any kind to be transported from one place to another.

The invention is especially designed for use in connection with the handling of brick about a brick-yard, but is adapted for use in connection with the handling of freight or packages of any kind.

In using my device a traveling crane is con structed, the same being mounted upon tracks so that it may be moved laterally, and thus cover a certain amount of territory. Upon this traveling crane is mounted a truck, from which my device is suspended, such truck being provided with means by which it may be moved to any point upon the traveling crane. This construction makes it possible to pick up or deliver a package at any point within the area covered by the traveling crane.

In the drawings the traveling crane is not shown in detail. It may be constructed in any suitable or desired manner. As shown in the drawings, the crane is provided with laterally-extending beams A, upon the upper surface of which are mounted the rails A which form the track for the truck carryin g my device. At the ends the crane is provided with a cross-beam A and wheels A which run upon stationary rails A located one beneatheach end of the crane. The crane may be moved by any suitable mechanism, and as these features do not form an essential definitive part of my invention they have not been shown in detail.

Upon the traveling crane is mounted a truck consisting of aframe B, having wheels B journaled therein and running upon the rails A of the crane. A gear-wheel B is mounted upon the axle of one set of wheels B, and upon a shaft B which projects beyond one side of the truck, is mounted a pinion B which meshes with the gear 13 Upon the outer end of the shaft B is secured a wheel B preferably a groovedwheel, adapted to receive a chain B and the upper end of the wheel B is preferably covered by a guard B, which prevents the chain from being displaced. The chain B is an endless chain and hangs down alongside of the truck to such a point that it may be conveniently engaged by the operator, so that by pulling down upon the chain the truck may be moved to any point upon the crane.

Four suspension-rods b are secured to the truck and extend downward upon each side of the beams A, forming the crane. To the lower ends of said rods is attached a plate 12, forming the lower member of the swivel and having a central aperture through which extend the ears b of a plate b forming the upper part of the swivel, said plate 11 havinga flange projecting over a portion of the plate I). Between the two plates are placed a series of balls 19 working in grooves in both plates, thus forming a ball-bearing by means of which the device may be readily turned as may be needed in handling the load. The lower plate I) is also provided with a detachable flange or ring I), which extends over the outer edge of the plate b and prevents the possibility of the latter rising. The plate b may be further secured to the frame which carries the load by means of a bar I), which passes through openings in the plate 19 and has its ends secured to a frame beneath the swivel. This construction of a swivel joint or pivot is simply one form which may be used, as swivel-joints of other construction may be used instead of that described, the exact construction of the joint not being material, except that it should be such as will prevent its suspended frame from tiltingsidewise. Suspended by means of said swiveljoint is a frame upon which is mounted the operating mechanism of my device. Beams 0 extend laterally of this frame and carry at each end trusses formed by the inclined bars 0, rods C and bolts 0 Bars C extend from the upper portion of each truss and connect at their outer ends with posts 0 which extend downward to a connection with the inclined bars 0. Upon each end of the trusses is secured a bar D, which at its ends is inclined downward to form inclined tracks upon which the carrying-rods are moved in order to raise the freight. Near their lower ends these bars D are secured to a bar D, which is secured to the lowerside of the truss ends. This gives a firm support for the inclined track-bars D. At each corner of the frame thus formed is a carrying-rod G,which extends downward to near the floor of the warehouse in which the device is to be operated or to near the floor of the surface upon which the freight is to be deposited. At its lower end each rod G is preferably slightly increased in diameter and is bent to one side, forming a hook G, and the ends of two rods G upon the same side are connected by a bar G which, as herein shown, is of angle-iron. These bars G are adapted to be placed beneath the freight or package to be handled and to have said package carried thereon while being transported. The upper ends of the carrying-rods G are supported upon shafts D extending between two of the carryingrods,and upon said shafts are secured grooved wheels D ,which roll upon the inclined tracks D. Upon said shafts and inwardly of the tracks D are also secured grooved wheels 61*.

Upon the upper and central portion of the frame is secured a shaft d, which has at each end drums d, forming a Windlass. To these drums are secured one end of cables D which pass about the wheels d and have their other end either secured to the frame or passing onto the wheels upon the opposite side of the device. As herein shown, the latter construction is used, the two ends of the cables being secured to the Windlass-drums and the body thereof passing about the wheels d and guide wheels or pulleys D Upon the shaft 01' is mounted a gear-wheel F in mesh with a pinion F mounted upon a second shaft F, to which latter is secured a hand-wheel F and a ratchet-wheel F a pawl F secured to the frame, engaging the ratchet-wheel and preventing backward rotation of the wheel, the pawl being freed by means of a hand-lever F connected thereto, as shown in Fig. 1. By turning the hand-wheel F the Windlass may be operated so as to wind up the cable D which will cause the rollers D to travel upward upon the inclined tracks D and thus raise the carrying-bars G and whatever is supported thereby.

For convenience in lowering a load thewindlass-shaft d is provided with a friction-drum E, about which passes a friction or brake band E, secured to a lever E, which may be operated by means of a rod or cord E connected to the outer end of the lever and extending downwardly within convenient reach of the operator. By releasing the pawl F and applying pressure to the brake-band the load may be lowered gradually and easily without any danger of breaking even the most fragile materials.

A bar II is loosely attached to each one of the carrying-rods G, which are connected by the bar G at the lower end. Each bar II is constructed, as clearly shown in Fig. 3, having a loop h formed in each end and surrounding the carrying-rods G, and the bar is suspended from the frame by means of links H. The central portions of the bars 11 are connected by the arms II and links I with a lever I, movable in a guide 1 The arms I1 are preferably secured rigidly to the bar II, and the links I are pivoted to the arms and to the operating-lever I. The lever I is pivoted centrally upon the frame, and by swinging the lever I in one direction the two bars H upon opposite sides of the device will be drawn toward the center, thus swinging the lower ends of the carrying-rods G inwardly. They may be thus handled so as to place the bars G secured to their lower ends, beneath the edges of the package to be raised.

In the special use of this device mentionedthat is, in handling brick in the process of manufacturethe brick would be stacked upon a platform having its edges projecting in such a manner as to accommodate the bars G This is shown in Fig. 2, in which the platform J has several layers of brick stacked thereon, the brick being supported by frames J. By the means described and also by the use of cars running upon depressed tracks within the drying-sheds bricks maybe cheaply transported from the machine to the dryingsheds and also to the kilns. In the same manner freight may be readily handled in a warehouse or material transported during manufacture.

The use of my device is not limited to any special purpose. It is adapted for use in any place where large quantities of material are to be handled, and especially for manufacturing purposes where material has a certain uniformity in character.
