Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed March 3, 1913. Serial No.'751,834.

To all whom it may concern Be it known that I, WILLIAM F. Iznr'r, a citizen of the United States of America, and a resident of the town of Oak Harbor, in the county of Island and the State of Washington, have invented certain new and use ful Improvements in Aerial Cableways, of which the following is a specification.

My invention relates to elevated cable tracks from which the load is suspended, having more particular reference to a structure of this character designed primarily for use in the conveyance of logs, and has for a fundamental object the provision of an cilicient structure that can be readily installed.

A further object is to provide a mechanism wherein provision is made for securely holding the flexible track and preventing abrupt angular portions or shoulders therein at the points of suspension, thereby insuringof a comparatively smooth and even running of the carrier.

Other objects will be set forth as my description progresses, and those features of construction, arrangements and co1nbinations of parts on which I desire protection succinctly defined in my annexed claims.

Referring to the accompanying drawings wherein like numerals of reference indicate like parts throughout: Figure 1 is an end elevation, with parts broken away, of one of the track hangers and a carrier shown as in use. Fig. 2 is a side view of the hanger, a portion thereof being broken away. Fig. 3 is a similar view of the carrier with portions broken away. Fig. 4 is a fragmentary showing of the hanger supporting the track and illustrating by broken lines the latter as sagging as under weight of the load of the carricr, a portion of the hanger being broken away. Fig. 5 is a vertical cross-section taken on line 55 of Fig. 4. Fig. 6 is a fragmentary plan, illustrating more particularly one of the approach sections in proper relation to the hanger, and Fig. 7 is a perspective illustrating my invention as in use, the track and some of the flexible stays being broken away.

Referring to the drawings by numerals of reference, 1 indicates a flexible track, consisting of suitable length of cable, 2 a suitable support, and 3 my improved hanger. Hanger 8 which is of substantially C-form has the upper end portion of its body turned downwardly to provide a hook 4: with which a suspending medium, as for example a cable 5, which is connected with support 2 in any suitable manner, is engaged. The terminal portion of hook 4 and the lower portion of the hanger proper are both formed with eyes, as 6, 6', for engagement with suitable stays, as 7, 8 which will normally extend in opposite directions and be fastened to near by stumps or be otherwise anchored. The upturned lower portion of the hanger body which is of greater width than the opposing end portion thereof, is formed in its upper face with a seat 9 for cable 1, this seat consisting of a groove having down-turned end portions, see Figs. 2 and 4, which open into recesses 10 provided in the opposite side portions of hanger 3. Recesses 10 have their inner walls provided with pockets 11 for reception of tongues 12 of suitable cable shields 13. Thesetongues 12 engaging in pockets 11 will obviously prevent the unseating of cable 1 from its seat or groove 9. Track shields 13 which conveniently consist of longitudinal sections having concave up per portions embracing cable 1 and being held to firmly clamp the latter by bolts, as 14, have their inner end portions freely and swingingly engaged in recesses 10. They are therefore guided by the hanger in a manner tending to overcome lateral swinging of the cable. As the cable 1 sags under the weight of a carrier, to be described, the connecting shields 13 move therewith, as for example, as shown, in the dotted position in Fig. 4:, thereby preventing any abrupt shoulder in the track at its point of engagement with the hanger.

My improved carrier 20 is open at one side so that it can be readily positioned on cable 1 and receive the lower portions of the hangers in passing the same, as will be readily understood by reference to Fig. 1. Carrier 20 comprises a body consisting of upper and lower sections 20, 20 pivotally connected, as at 21, for relative movement of the lower section in a direction longitudinally of cable 1. Upper section 20 which is substantially of inverted U-form is comparatively wide and provided with a pair of bearing wheels 22 adapted for travel on cable 1.

Section 20 has its lower portion directed inwardly to lie directly under or a little inwardly of a vertical line intersecting cable- 1, and the terminal portion of said body section is preferably formed with an eye 23 for the attachment of cables 25 or other means for supporting the load. In this, the preferred embodiment of my invention, I aim to have the point of connection with suspension member 5 in substantial vertical alinement with cable or track 1 and terminal portion of carrier section 20". By pivotally connecting carrier section 20", the latter are free for movement with respect to section 20, as limited by stops 26 of the latter, incident to conveyance of the load over inclined sections of the track.

My invention is simple and through the provision thereof, an aerial cableway can be strung throughthe forest and run on irregular lines. The supports 2 can therefore obviously be the trunks of standing trees, or towers or supports of other form provided as required, without departing from the spirit of my invention as defined in my annexed claims.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of America,

1. In apparatus of the character described, a track hanger comprising a body portion having an up-turned lower portion formed with a seat for the track, said body portion -having its upper portion formed into a hook for engagement with a supporting medium, the said hooked end portion of said body being formed with an eye adapted for engagement with an anchoring means.

2. In apparatus of the character described, a track hanger formed in its opposite side portions with recesses, and shield means for the track pivotally engaged in the side recesses of said hanger.

3. In apparatus of the character described, a track hanger, said hanger being formed in one side portion with a recess, a shield for the track normally secured to the latter and swingingly engaged in the recess of said hanger, and interlocking parts on said shield and hanger for preventing disengagement of the track from said hanger.

4. In apparatus of the character described, a track hanger, said hanger being formed in one side portion with a recess, a shield for the track normally secured to the latter and swingingly engaged in the recess of said hanger, and interlocking parts on said shield and hanger for preventing disengagement of the track from said hanger, said hanger comprising longitudinal sections det-achably secured together and normally embracing the track.

5. In apparatus of the character described, a hanger formed with agroove adapted to receive a wire or cable track, the said groove having down-turned end portions, said hanger having recesses in proximity to the end portions of the groove thereof, and shields for the cable track having their inner end portions freely received in the recesses of said hanger.

6. In apparatus of the character de scribed, a hanger of substantially C-form, the up-turned lower portion of said hanger being provided with a cable track-seat, means adapted to be engaged with the upper portion of said hanger for suspending the same, and a carrier comprising a frame composed of upper and lower sections pivotally connected for movement of the lower section lengthwise of the track, the upper section of said carrier frame being provided with a roller for engagement with the track, the lower frame section of said carrier being turned inwardly to have its terminal portion in substantial Vertical alinement with the track.

Signed at Seattle, lVashington this 25th day of February, 1913.
