To all whom it may concern:

it known that I, JOSEPH H. Dicnmson, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Portable Cableways, of which the following is a specification.

My present invention relates to the improved portable cableway-and has particular application to an apparatus of the type referred to adapted especially for logging operations.

In carrying out the present invention it'is purpose to provide a special cableway Wll ch may be moved from place to place as the occasion may require, without i e-rigging thespars and the like.

It is .also my purpose to provide an improved cableway having a supporting spar for the various ropes employed, so that the entire apparatus may be readily and speedily moved along the track from place to place, this being an advantageous feature when logging in mountainous districts where it is oftentimes inconvenient or impossible to em ploy a standing spar, such as an adjacent tree.

A further object of my invention is to provide means by which the guys for the spar may be readily tightened and loosened as necessary, and I also lead or direct said guys in such a manner as to obviate the possibility of the guys interfering with the various leads of the ropes of the cableway, such as the'.skidding ropes, the carriage-actuating ropes, and the like.

By means of my improved construction, I also dispense with the employment of a large gang of riggers, as it is unnecessary to re-rig the head, or portable spar every time the cableway is moved, as is the case Where permanent supports are employed.

A further purpose of the invention is to so mount the head spar upon the frame of the machine that it may be readily raised and lowered, this being a valuable feature when the apparatus is moved from place to place, as the tower may be lowered toward the frame, thereby obtaininga low center of gifavity for the machine. 7 v

'With these and other objects of a similar naturein view, 111 invention consists in the construction, com motion and arrangement of parts'set forth in and falling within the scope of the appended claims.

In the accompanying drawings, Figure l is a View in side elevation showing one embodiment of my apparatus; Fig. 2 is an end view, the ropes of the cableway being removed, said view showing means for controlling the guy ropes running down through the center of the spar; F 2 is a detail of the preferable form of joint to permit the spar to yield in any direction; Fig. 3 is another view in side elevation of the cable way apparatus embodying my improvements in slightly modified form; Fig. lis an end view of the machine shown In Fig. 3, the cableway apparatus being omitted, showing guy ropes passing down through the spar, and also the operating drums 27, 27 with their ropes to raise and lower the spar; Fig. 5 is a plan View of the top of the supporting spar and showing the manner of supporting the guys at such. point; Fig. 6 is a cross sectional view taken through a portion of the tower on the line G6 of Fig. 4, showing the circular attachment which allows the automaticadjustment of the main cable and lead blocks in any desired direction around the spar.

Referring now to the accompanying drawings in detail, and especially to Figs. 1 and 2,-A indicates a frame or platform of the machine provided with suitable supports 5, adapted when the machine is in its stationary position to straddle the track. 6 designates jacking means for raising and lowering the frame upon a logging car B for transportation. Carried by the platform A is a supporting vertical framework 7, of any suitable type carrying the swinging or pivoted spar 8, the latter being fulcrumed as at 9, upon the support 7. The manner of pivoting the spar is more clearly shown in Fig. 2,-in this instance, suitable bearings 1O, 10 being secured to the supporting frame 7 and Within said bearings lie the trunnions 11, ll of the spar, said trunnions being so socketed in their bearings as to permit the tower to have a slight play or movement at the top in any direction, so that the unequal strain of the guys may be compensated for. Upon the frame A is mounted an engine designated as an entirety by the letter C, said engine being of any Well known and approved type, such as the Lidgerwood engine, and embraces in its construction a plurallty of drums for operating the various ropes of the cableway. As this engine is of a well known construction it is unnecessary to de- Q i I 936,425

scribe the same in detail here, the illustration in the present drawing being merely conventional. The cableway itself 1s also oi a well known type, a designating the main cable secured in a manner hereinafter de:

scribed, to the portable head spar, and at its tail end to the tail tree 6. o designates the carriage adapted to travel along said main cable. (Z indicates the onthaul rope. for the carriage, c is the inhaul, or what is commonly known as the skidding line, and f designates what is commonly termed the slack-pulling line employ ed to overhaul the slack-pulling drum on the carriage to permit the lowering of the fallrope g carrying the grappling tongs or logeneaging means it. The line (Z is operated by the drum 2' of the engine C, the line 0 by the drum 7' of the engine and the line f by the drum 7c. D indicates asecond engine mounted upon the frame, said engine in this case being provided with 'lhree drums. The drum Z operating the line 12, this line tuning over a pulley 12 attached to the spar. This line [2 is employed for changing the main cable "from one setting to another. Upon the forward shaft in are mounted two drums a. a, side by side, one of said drums, an ordinary slip drum, controlling the heel-block line 13, which runs over suitable pulleys 14, 15 and 16. and operates the block and fall 0. This line may be termed the heel-block line and serves as a tension means in conjunction with the block and tall for 'tensioning the main cable. Such a tension device is shown in an earlier patent to Miller & Dickinson No. 8 52%, and it is unnecessary to further describe the operation of the same here. The srcond drum n is employed for operating the car-spotting, line 17, this line when not employed. for spotting the cars beneath the loader is preferably connected to the lower end 18 of the tower and maybe employed to assist in raisingand lowering such Carried preferably at the forward end of the frame is a. turntable E carrying a. third engine F, said engine having suitable drums/p and operating the loading line r and the swinging lines a respectively. b'nch construction is shown in the patents to Miller LQ7 I)iCklllSOll No. 726,325. dated April 28, 1903, and need not be described here further in detail.

When the tower is in its elevated position, as when the apparatus is employed in the actual operation of logging .it is, of course, necessary to guy or secure the tower against movement and in the present invention 1 have shown a novel form of guy lead. Reterring', tor instance, to Figs. l and 9., l provide a suitable number of guys 15) which, for the sake of convenience and distinction, may be termed ground guys; that is to say, the lower end ot' said guys are secured to suitable points of support as the stump :20, while.

l i l the upper ends of said guys pass over sheaves '21 jonr aled in the collar 22, adjacent to the top of the spar, said guy ropes then. leading down through the interior of the tower and over suitable sheaves 23 tom their respective guy tightening drums 24;, in the present instance, mounted on the sup porting frame 7 and designed to be open ated by hand, although I Wish it to be understood that I may extend said guy ropes to power operated drums mounted at any suitable position, either upon the platform or frame, or upon other portions of the apparatus.

The advantages incident to the construcso tion of apparatus shown in Figs. '1 and 2 will be readily apparent. The spar or tower may be easily and readily raised and lowered by the means described and when. 10wered for transportation, may rest or lie above the loading boom, and furthermore, the arrangement of guys shown, that leading such guys into and down through the spar enables me to obtain a universal lead of the various operating ropes of the o0 rableway; that is to say, said guys are located in such position that while inaintain ing their etliciency as supporting means, they do not interfere with the operation of the cableway ropes.

In Figs. 3, 4, and'G I have shown a slightly modified form of arrangement as concerns the raising-and lowering of the tower, the tower 8 being provided at its fulcrunnal point with a bull-wheel 25 actu- 10's atcd by a rope '26 operated by suitable drums 527, said rope passing over suitable guys 28 to obtain the correct lead. In raising and lowering the construction of tower shown therein the operation will be apparent. When the drums 27 are rotated in one direction the bull-wheel is actuated to lower the tower and when rotated in the opposite (ii-- rection to raise the latter.

While I have herein shown and described preferred terms of my invention, 1 Wish it to be. imderstotal that I do not limit myself to all the precise details of construction herein delineated, but that modification and Variation may be made without departing from 11-5 the spirit of my invention or exiceeding the scope of the claims.-
