The present invention relates to towing apparatus and more particularly to apparatus for towing or pulling skiers uphill.
An object of the invention is the provision of
5 towing apparatus of generally improved design.
Another object of the invention is to provide towing apparatus of the above character which is relatively inexpensive in construction.
A further object of the invention is to provide
0 towing apparatus of the above character which can be erected and operated at a comparatively low cost.
Still another object of the invention is to provide towing mechanism of the aforesaid char
5 acter which is efficient and reliable in operation.
Other objects andadvantages of the invention will become apparent as the description progresses.
In the accompanying drawing forming a part
0 of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:
Figure 1 is a side elevational view showing the apparatus in assembled arrangement for towing 5 skiers up a hill
Figure 2 is a fragmentary top plan view showing the lower portion of the apparatus
Figure 3 is a similar view of the upper portion of the apparatus
0 Figure 4 is a side elevational view of the same Figure 5 is a perspective view of the drive mechanism and
Figure 6 is a rear end view of the same.
Referring to the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the upper portion of the apparatus that is that portion at the top of a hill embodies an upstanding support standard 10 in the form of a vertically anchored post
io rigidly braced by an inclined brace bar I I. To an eye 12 on the post IO is connected one end of a block and tackle mechanism 13 of the conventional chain hoist type disposed so that its opposite end connects with an eye on the end
5 of a Ushaped pulley bracket 14 which rotatably supports a grooved pulley 15. To the outward extension of the pulley bracket 14 is connected a depending rod 16 provided with a weight 11 on the lower suspended end and adapted to maintain
c0 the pulley 15 in an approximately vertical plane. Over the pulley 15 is trained the upper end loop of a continuous towing rope 18.
At the lower end of the apparatus that is at
the foot of the hill or slide is mounted rope
i5 drive mechanism which may constitute a striped
automobile chassis and particularly such as has outlived its usefulness as a vehicle. The chassis frame indicated at F is horizontally supported upon posts 20 anchored in the ground. On the outer or rear end of the frame is mounted a shaft 21 in the form of a solid axle having grooved pulley wheels 22 and 23 fixed on the ends and arranged in a vertical plane. On the intermediate portion of the shaft 21 is secured
a drive gear 24 in mesh with a pinion 25 fixed 10 on a drive shaft 26. The. drive shaft 26 may correspond to the vehicle propeller shaft and connects with the engine generally indicated at E through the usual transmission and clutch mechanism. On the chassis frame F adjacent the pul 16 leys 22 and 23 are rotatably mounted a pair of idler pulleys 21 and 28 arranged in a plane inclined from the horizontal as shown at Figures 5 and 6 and having an auxiliary loop of the towrope indicated at L trained thereover. This 20 arrangement enables the training of the towrope so that the takeoff portion or reach indicated at T is driven from the top of the drive pulley 23 while the opposite return reach indicated at R comes onto the bottom of the opposite complementary drive pulley 22.
This formation of the drive mechanism acts to effectively space the opposite sections or reaches of the towrope vertically and laterally the upper towing reach being arranged uppermost as g0 shown at Figure 1. The bottom return portion or reach of the rope is guided on vertically arranged pulleys 30 journalled on gudgeons mounted in the upper portion of a plurality of spaced posts 31. 36
This apparatus provides efficient means for towing or pulling skiers up a hill inclination on or adjacent to a skiing slide. Its relatively simple construction and the provision of means for utilising a relatively inexpensive power unit en 40 ables erection and operation at a comparatively low cost. The block and tackle mechanism connecting the upper pulley with its supporting post also enables adjustment so that the rope may be made suitably taut while in use and loosened 46 when the apparatus is inoperative.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes as to the shape size and arrangement 50 of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
