ELEVATED CARRIER.

SPECIFICATION forming part of Letters Patent No. 487,485, dated December 6, 1892.

Application filed October 13, 1891. Serial No. 408,564. (No model.)

To all whom, it may concern:

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

My invention relates to elevated carriers for conveying logs, lumber, stone, coal, cane, and other bulky materials, and is particularly useful for conveying logs through the forest from the stump to the sawmill.

The object of myinvention is to provide an elevated carrier which can be rapidly erected and strong enough to support heavy loads and which can be constructed at small cost. To this end I preferably employ, in combination, a suitable supportingframework of peculiar construction, hereinafter to be described, a track-beam, and a track-rail consisting of a round rod or pipe supported upon bearers having one end fashioned to grasp the track rod or rail and the other adapted to pass into or through the track beam. Where forest trees are so situated that they can be utilized as supports for the trackbeam, I may use them for the uprights and bolt or otherwise fasten thereto the longitudinal track-beam, to which the track-rail is secured. In some instances it may be found expedient to secure this track-rail upon the outer and upper corner of the longitudinal beam; but I prefer to support the track-rail, as before stated, upon bearersinserted in the face of the longitudinal beam.

, In the accompanying drawings, Figure 1 is a side elevation of my improved log-carrier, showing a section thereof supported by two trees. Fig. 2 is across-section thereof, showing a bucket for carrying coal, ore, &c., suspended from the truck. Fig. 3 is a perspective view of a section of the carrier, showing the track supported by a speciallybuilt frame consisting of parallel uprights with transverse cross-beams supported upon their outer ends and the track-beams suspended therefrom by hangers. Fig. at is a perspective View showing a traclcsupport of modified construction. Fig. 5 is a similar view showing the preferred construction of such modified form. Fig. 6 is a cross-sectional view thereof, and Fig. 7 is an enlarged detail view of one of the track-bearers.

In the drawings, 8 represents the bodies of trees, which may be utilized wherever convenient for the vertical supports of the carrier-frame. 9 represents a beam, which is secured in longitudinal position at a suitable height above the ground to the bodies of said trees. As shown in Figs. 1 and 2, these beams are square timbers secured by the bolts 10, passed through the bodies of the trees, and in order that the carrier may be adapted for the transport of heavy loads I have shown in said figures an additional bracket or brace 11, secured by bolts 12 to the trees. Upon the outer and upper corner of the beam 9 I have shown a track-rail 12, which is a half-round strip of iron and adapted to support the wheels 13 of the truck.

The preferred form of truck is shown in Figs. 5 and 6 of the drawings and comprises a frame 13 in the form of a band, which incloses a pair of truck-wheels 13. A hanger 13 is secured to the outer side of this band and is curved so that its lower end hangs beneath the track-rail, as clearly shown in Fig. 6, and is provided with a swiveling hook 13. This arrangement distributes the load between the wheels and prevents their cramping or binding. 14 represents a log supported from such truck, and 15 represents a bucket, which may be employed for the carrying of coal, ore, stone, or the like.

In all cases I prefer to employ instead of the track-rail above mentioned a round trackrail 16, such as shown in the several views of the drawings. or bar, either fiat, round, or angular in crosssection, or it may be a pipe or tube.

17, Fig. 7, represents a track-bearer, preferably constructed of wrought iron or steel, and may have its shank passed through the trackbeam, as shown in Fig. 3, and, fastened with a nut, or it may have a pointed shank, as shownin Figs. 2 and 4:. In allcases, however, this track-bearer has its outer end upturned, as clearly shown in Fig. 7, and this upturned end is bifurcated to provide points 17, which may after the track-rail is inserted between them be hammered down against such rail, so as to hold it firmly in position and prevent This track-rail may be a rod framework may be constructedas, for exam? ple, as shown in Fig. 3 of the drawings. In this instance the parallel uprights 18 support cross-beams 19, from which depend hangers 20, having upturned ends passed through the track-beam 9 from its lower side; but abetter form is illustrated in Figs. 4, 5, and 6 of the drawings, that shown in Fig. 5 consisting of.

the short upright beam 21, with the diagonally-placed beam 22, having its ground end weighted, and with the track-beam 9 resting. The preferred.

directly upon its upper end. form of construction, howevetgis shown in Figs..5 and 6, where, instead of weightingthe ground end of the inclined beam, I connect it.

to a ground timber 23, upon which the lower end of the upright bears. movement of the upright, I provide the stud or pin 24, which is secured in the ground timber with an end of said pin projecting,

above the face of the ground timber. The upright has an aperture to receive this pin and in this way may be readily removed. Of

course the pin may be secured in the postand have an end sharpened to enter the ground timber, or the latter may have an aperture to receive said pin. Inthis figure I have shown the track-beam supported by a hanger25, havingbolts 26 27 passed through the beam and i In this case the bracket 11 .is

the upright 21. dispensed with. This furnishes a firm and secure foundation for the supporting-framework, and the entire structure, which maybe builtof rough timbers instead of square tint.- bers shown, is cheap to construct while very strong and efficient for the purposes intended.

A carrier of this kind can be very rapidly constructed, and the frame'workmay be made from materials-found ready to handiin aforest, and when once constructed -there .is little liability of its getting out of repair, even in extended use.

I do not claim in this applicationthe form of framework shown in Fig. 4 hereof, as the same is shown and described in .my application, Serial No. 396,487, filed. June 16, 1891, and is illustrated here to show the application In orderto prevent of my track-bearers to the different forms of frames.

Without limiting myself to the precise details of construction nor arrangement of parts, I claim I 1. In an elevated carrier, the combination, with a supporting-frame comprising suitable uprights and a horizontal track-beam supported by, said uprights, of a track-rail and bearerstherefor, said bearers having their shanks adapted to pass into or through the beam and their outer ends upturned and bifurcated to provide seats for the track-rail and said bifurcations being adapted to be bent to securely embrace the rail, substantially as described.
