ELEVATED CARRIER.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed July 23.1906. Serial No. 327.354.

citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Elevated Carriers, of which the following is a specification.

My invention relates to elevated carriers such as are generally used for carrying feed,

litter and other products, and it consists 1 principally of an improved form of truck whereby-the track wheels will be securelyheld in place andyet be free to run on a u per ends of the brackets O are preferably curved track, or on curved track sections l used to connect together two sections of track running at an angle, so as to form a continuous track-way. Also, of other features which will be set forth in the specification and specificallypointed out in the claims.

In the accompanying drawings forming a part of this specification, Figure 1 is a front perspective of a carrier embodying my invention. Fig. 2 is a rear perspective of one horizontally disposed bar preferably made of angle iron and having downwardly turned ends B to which the necessary attachments may be connected.

C represents upwardly extending brackets which are secured at their lower ends to the carrier frame and are extended up and over the track.

Interposed between the main brackets and the frame are supplemental brackets D extending up under the track. A short distance above the frame the main brackets are bent out laterally from the vertical line of their lower ends and are then further extended and their upper ends are bent inwardly substantially at right angles to their bodies so as to be substantially in a vertical line above the bar B. The supplemental brackets are extended up a short distance and their upper ends are also bent inwardly at substantially right angles to their bodies 1 so as to stand in the same vertical line as the Be it known that I, ALBERT H. NELLER, a l

upper ends of the main brackets.

Holes are made in the upper ends of the brackets O and D in vertical line with each other and pivots are inserted therein. In the lower brackets threaded pins E having nuts F and G are preferably used. The nuts F are placed above and the nuts G below the ends of the brackets and are drawn up securely so as to hold the pins firmly in place, and leave their upper ends projecting sufficiently to form a pivot.. I The holes in the one will hereafter be considered a description of the other.

J represents a housing which is adapted to carry a track wheel K, and also to turn on the ivots aforesaid. 'Thishousing is preferab y made of sheet metal and has its upper end bent U shaped. A bolt L is placed in the central part of the housing as shown, and a wheel K is mounted upon said bolt. The lower end of the housing is bent inwardly I substantially at right angles to its body so as I 1 to corres 0nd with the upper ends of the B is a carrier frame which is essentially a bracket and a hole 'is made therein to fit over and turn upon the pivot pin, E. In the upper end of the housing a hole is also made to receive the ivot in the brackets C. A block N is refzrably inserted in the upper end of the 4 ousing immediately below the hole therein.

To place the housing in position the set screw H is loosened, the lower end of the housing is set on the pivotE, the set screw is turned down so its point will enter the hole in the upper end of the housing and come in contact with the block N, and the lock nut I is turned down to hold the set screw in place. It will be seen that the housing carrying the wheel K will be free to turn at an angle to the bracket 0 in one or both directions as shown by cross section in Fig. 5. The object of this construction is to enable the carrier to run freely on a curved or crooked track, as well as to be transferred from one track to another running at an angle thereto by means of a bent or curved section joining the two tracks together. An illustration of the latter is shown in Fig. 4, in which A represents two suspended wire tracks crossing each other at an angle and M a curved section joining the two tracks together so as to form a continuous way from one track to the other for the carrier to run upon.

The section M is preferably made of a round rod or pipe. Its ends are cut away on the under side so it will fit over and partially or wholly surround the wires forming the tracks. If a pipe is used the wires may be passed into the ends and out of an opening on the under side of the pipe where it curves away from the track. If a solid rod is used, grooves may be cut on the under side along each end so as to fit properly over the wires, and the lips of the groove at each end may be hammered or bent in under to prevent them from springing off the track wires. It is also preferable that the ends of the section be beveled and reduced to substantially the same size as the wires, so that the wheels will run smoothly on and off the curved section. Furthermore, to adapt the wheels to run properly on the wires and on the curved section when of larger diameter than the wires, I form two grooves in the wheels. The larger groove, the size of which is shown by the dotted line 0 is intended to fit the curved section M, while the smaller groove, the size of which is shown by the dotted lines I is formed in the center of the larger groove, and is designed to fit the wire to which the section M is connected. By this means the wheels Will always run freely and evenly on the wire and on the curved section connecting them together no matter how much the carrier may be swung sidewise in passing over the curved section from one track to the other. Neither will it be necessary to kink the track wires nor to use extraneous clamp ing device to hold the section Min place.

In order that the brackets C may be more securely braced to the carrier frame, I have split their lower ends and spread them apart so as to form two diverging braces Q and R which are bolted at separate points to the bar B. The supplemental brackets D are alsowidened at their lower ends so as to take in both of these bolts, and will therefore be held more securely in place. To further strengthen the frame and brackets the braces R may be extended down and bolted to the depending ends of the bar B.

What I claim is 1. In elevated carriers, overhead tracks set at an angle to each other, a curved section joining said tracks together so as to form a continuous way, a carrier frame, a pair of upwardly extending brackets secured at their lower ends to said frame, one member of which extends up under and the other up by and'over the track, housings pivoted between said brackets so as to turn at an angle thereto, and wheels adapted to run on the track and en the curved section thereof mounted in said housin s.
