ELEVATED CARRIER.

SPECIFICATION forming part of Letters Patent No. 488,765, dated December 27, 1892.

Application filed February 6,1892. Serial No. 420,551. (No model.)

To ctZZ whom it may concern.-

Be it known that I, ALFRED T. KELLIHER, a citizen of the United States, residing at Bethel, Maine, have invented certain new and useful Improvements in Elevated Carriers, of which the following is a specification.

This invention relates to certain improvements in elevated carriers of the class described in my patent, No. 448,766, dated March 24, 1891. Among other uses to which these carriers are applied is that of transporting logs from the stump to the mill, and when applied to such uses it is desirable to so construct the track and carriers that they can be erected readily and without skilled labor.

The object of my invention is to provide a construction having these desirable features, and one feature of the invention relates to a novel form of hanger for supporting the abutting ends of the timbers which support the track rail.

Another feature of my invention relates to a brake for the wheeled carriage by means of which the logs or other material are transported.

In the accompanying drawings, Figure l is a perspective view of an elevated carrier embodying my invention and applied to the use of transporting logs. Fig. 2 is a sectional view through the track beam and track rail. Fig. 3 is aperspective view showingaspecial hanger for supporting the abutting ends of the track beam. Fig. 4 is a similar view of a modified construction of the same; and Figs. 5 and 6 are detail views of a brake for the carriage.

In the drawings, A, B, 0 represent the supporting frame work.

D are track timbers or stringers which are preferably squared or have at least one plane face and which will be of convenient lengths for transportation and erection. The abutting ends of said timbers are conveniently supported by means of the hanger shown in Figs. 3 and 4. The hanger of Fig. 3 comprises the T- headed shank E integrally formed with or joined to the bands or straps F which may be further connected and braced by the bar G. The straps F provide an open body and are adapted to receive the adjoining ends of two of the stringers which may be prevented from working out by the spikes g. The upright C has the vertical notch cto receive the edge of stringers from pulling out of the hanger.

the shank E of the hanger, while the T-head of the latter takes a bearing upon the upper surface of said upright. This hanger is preferably made from wrought iron as it is desirable that it shall have great strength and little weight, but it may be made from malleable iron or other suitable material. In the form of construction shown in Fig. 4, the hanger is preferably made from a piece of sheet steel or thin, wide bar iron, one end of Which may be split longitudinally, as shown at e, Fig. 4, and the ends turned out to form the T- head while the margins of the sheet arepressed or stamped together, the body forming a broad band of such width as to take the place of the separate straps F of the construction shown in Fig. 3, while the staple H serves to prevent the two It is evident that these hangers. may be put in place and the track very rapidly erected,and to facilitate the rapid construction of the track I employ a special form of rail shown in the drawings. This rail, marked I, has a straight, flat web and ahead of any suitable form,that shown in the drawings being rounding the better to adapt it to the wheels of the carriage usually employed in this form of carrier. The flat web adapts the rail to be spiked or bolted directly to the side of the track beam or stringer, while the head projects above the surface of said stringer to receive the wheel. This track rail may be permanently fixed to the stringers so that the track beams and rails can be moved from place to place in sections and put up together. The form of the rail particularly adapts it to the use intended as it has great strength vertically while the web being comparatively thin and the head light it may be flexed sufficiently to adapt it for securement to a crooked or irregular shaped track timber.

The carriage shown comprises a frame J within which are journaled the track wheels K and centrally between them the hanger L is affixed to the frame, its lower end being inturned and supporting the swivel-hook M.

In order to control theca/rriage, I have applied thereto a simple brake device, particularly shown in Figs.5 and 6. This comprises the brake shoe N, the acting face of which is curved both vertically and laterally whereby it is made to bear not only upon the bottom ICO of the groove, but also on the sides of the flange of the wheel. This shoe is moved by an operating screw 0 towhich it is loosely affixed by the headed pin P, the head of which rests in a recessp in the end of the shoe, the screw being threaded into the frame. By simply turning this screw the shoe is forced into contact with the carriage Wheel and the latter may be thus fastened at any desired point along the track.

I do not claim in this application the particular construction ofv frame work shown in Fig. 2 hereof, as the same is shown, described and claimed in my application, Serial No. 408,564, filed October 13,1891, and is illustrated herein to show the application of my improved hangers to such frame.

Without limiting myself to the precise details of construction, I claim:

1. In a carrier of the class described, the combination with the supporting frame work, of track beams composed of stringers or timbers and a hanger having ashank adapted to engage said frame work and an open body to receive and support the adjacent end of the stringers or timbers, substantially as described.

2. In an elevated carrier, the combination with the supporting frame work of a track composed of independent stringers or timbers, and a hanger having a shank provided with a T- head and an open body to receive the adjacent ends of the stringers, substantially as described.

3. In an elevated carrier, the combination with an upright timber of the supporting frame work, said timber having a notch therein, of a hanger having a shank adapted to enter said notch and a T- head to bear upon the timber, an open body to receive the ad jacent ends of the stringers or timbers, and suitable means for securing the timbers therein, substantially as described.

4. In an elevated carrier, the combination with a carriage having a frame and suitable track wheels, of a brake shoe interposed between the frame and the Wheel and an adjusting screw threaded into the track frame whereby-the shoe may be moved into and out of frictional contact With the wheel, substantially as described.

ALFRED T. KELLIHER.
