CAR-"HAUL.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed January 9, 1906. Serial No. 295,304.

the following is a specification, reference heing had therein to the accompanying drawings.

This invention relates to improvements in hauling apparatus of the class adapted both to propel and to control the travel of cars along grades.

It relates particularly to such a system in which a flexible endless cable or chain is extended around a c rcuit, along both the uploading and douuileading paths of which the travel of the cars is controlled by car-engagir-g elements carried by said draft device and each of which normally projects upwardly therefrom along both of said paths.

The object of the invention is to provide simple and efficient means for guiding the cabie chain from one run to the other in such mai or that the car-engaging attachments thereon will maintain the same relaticn thereto along both the uprun and downrun and will not be permitted to turn and twist the cable at the points where its course of travel is deflected.

The invention is particularly applicable for use in connection with an endless chain or cable haul having secured thereto and carried thereby car-engaging attachments which are mounted upon antif ictioi rollers a l which are adapted to be supported upon that run along guide or track ways provided along the up and down runs of the system.

Figure 1 is a side elevation of an apparatus sheave. Fig. 5 is a section on the line 5 5, Fig. 4. Fig. 6 is a plan view or a portion of one of the sheaves which is adapted to deflect the cable while maintaining the car-en gaging elements or arms thereon transverse to the plane of the sheave. Fig. 7 is a section on the line 7 '7, Fig. 6.

In the drawings, A represents as an entirety the endless cable or chain draft device;

B B, a pair of cooperating car-engaging attachments thereon C, a car having an attachment engaging elements C, and D the mechanism through which power is applied for actuating the endless draft device.

E and F represent conventionally-disposed parallel traclm'ays arranged for the greater part of their length at an inclination to the horizontal, and the former directing the travel of the uprunning cars and the latter directing the travel of the downrunning 0&1

As my invention does not pertain to the apparatus and the arrangement of parts as an entirety it will not be necessary to here give a detailed description of the same, and the parts hereinbefor referred to are simply shown for the purpose of illustration.

The attachments B B are arranged, as liereinbeiore referredto, in pairs. tachments B comprise a two-part cable-gripping element or clamp 1, separable on longitudinal lines and supported by four antifriction-rollers 2 and an upwardly-extending yielding arm 3. The antifiictionqollers 2 are mounted at i'icnt and rear on either side of the said clamp. The upper part of the clamp has upright webs or walls 4, supporting an inclined top wall 5. The yielding arm 3 is pivo ally mounted between the said upri lit walls 4, as indicated at 3, and it is normally pressed upward into engagement with the top wall 5 by means of a flat curved spring 6, having one end secured to the upper sui e of the upper part of the clamp and its free end bearing against the under surface of the said yielding arm. The attachments B likewise consist of a twopart longitudinallpsepai'able clamp 7, two pairs of antifriction-rollers 8, and an arm 9. This arm 9, however, is either formed integrally with or is rigidly secured to the top part of the clamp. Q 9 are wearing-plates secured to the upper end of the arm 9 and are adapted to engage with the attachment or arm C on the car.

10 10 indicate guide-rails arranged adjacent to the uploading and downloading runs of the cable and at either side of the vertical The atlCC plane of travel thereof and adapted to be engaged by the antifriction-rollers on the cabletrucks in their travel.

At the lower end of the system the cable is deflected or guided from itslower run to its upper run by a guide sheave or wheel 12. In most systems, as in the one here described, this guide-sheave at the lower end of the system is arranged beneath the trackways for the cars at this point and is slightly inclined to the horizontal. It is essential that the cable-trucks be guided from the downrun to the uprun in such manner that they will not turn out of position and twist the cable, since it is necessary that they should nor mally travel along both runs with their arms or dogs extending upwardly. The guiderails 10 10 for the antifriction-rollers extend to a point closely adjacent to the sheave 12. The periphery of this sheave is recessed at intervals, as indicated at 12, in order to receiv'e'the cable attachments or trucks, and between these recesses cable-guiding teeth 12 project alternately from one side of the wheel and then the other in the well-known manner.

13 are plates detachably secured to or formed integrally with the under surface of the sheave 1-2 at the recesses 12 therein. These plates form a bottom wall for the said recesses and extend from the inner wall of the recess outwardly a distance equal to the width over all of the cable-trucks. It will be seen that as one of the said trucks leaves the lower end of the guides 10 10 on the downrun and enters one of the recesses 12 in the sheave its antifriction-rollers on either side engage with the upper surface of one of the truck or attachment supporting plates 13 in such manner as to prevent the truck from turning and twisting the cable, The trucks travel around in this condition in the recesses in the sheave 12 until they start on their uprun, when they at once engage the guide-rails 1O 10 therealong.

The vertically-disposed sheaves at the upper end of the system, which are indicatedby 14, 15, and 16, are all of the same construction, so that only one of them need be described. Thus the sheave 14 is provided with recesses 14 at intervals about its periphery, which are adapted to receive the cable attachments in the well-known manner, and between these recesses the periphery of the sheave preferably carries the alternately-disposed cable-guide teeth 14. 16 16 are guide-plates having their outermost surfaces transverse to the plane of the wheel and each arranged at either side of the wheel and each extending across one of the recesses 14 therein. These guide-plates may be formed integral with the wheel, or they may be rigidly and detachably secured in position thereon in any desired manner.

Each one of them extends laterally a. sufficient distance to be in the plane of travel of the antifriction-rolls on the cable-trucks at i that side of the sheaves, and as the cabletrucks enter the recesses the antii'rictionrollers engage with the laterally-projecting guide-plates and are by them held from turning and twisting the cable. The guiderails 10 10 for the antifriction-rollers are at the upper end of the system likewise carried to a point in close proximity to the-peripheries of the guide-sheaves for the cable, so as to insure the proper directing of the cabletrucks onto the sheave 14 and from the sheave 16 onto the downrunning guides.

The operation of these cable-attachment engaging and guiding devices on the sheaves will be readily understood. As each attachment or clamp leaves the guide-rails 10 10 and enters one of the recesses in the periphery of the adjacent sheave it is engaged by a suitable plate or by laterally-extending ribs or flanges carried by the sheave and is prevented from turning and twisting the cable. So, too, as the attachment leaves the sheave to pass onto the guide-rails 10 10 it is properly directed thereon with its car-engag1ng element or elements projecting upwardly.

I am aware of the fact that in earlier endless-cable haul systems devices have been provided for preventing the turning of the cable attachments as they are deflected by a guide wheel or sheave from one of their paths of travel to another in order to prevent the twisting of the cable-such devices, for example, as are shown in Patents Nos. 93,361, of August 3, 1869, to Smith; No. 788,861, oi May 2, 1905, to Wagner, and No. 722,951, of March 17, 1903, to Damron. In these earlier devices, however, the attachments are kept from turning by means of a stationary guide-rail, with which they engage and which extends concentrically around the periphery of the guide-sheave and closely adjacent thereto; but in these earlier devices frictional resistance and wear and tear occurs between the said stationary guide-rail encircling the sheave and the parts of the cable attachment with which it engages. It will be noted that in my construction the cable attachment engaging and guiding devices rotate or travel with the cable-deflecting device and that in this particular they are essentially different from the earlier devices which are intended toperform substantially the same function.

I make no claim to the arrangement of parts shown in the drawings for applying power to the endless draft device for actuating it, as I believe the same to be the invention of Archibald WV. F. Steckel and shown and described in his application for patent, Serial No; 269,873, liled July 15, 1905. Where the drive is thus eflected. it

will be noted that guide-rails 10 10 should eXtend from the sheave 14 to the powerapplying sheave 17 and from the latter to the sheave 15. The power-applying sheave 17 should be of construction similar to that of the sheave 12 and is so indicated. The sheaves, with the plates or guides extending transversely from either side thereof at the cable-truck-receiving recesses, are adapted to deflect the cable while maintaining the car-engaging arms carried by the trucks in the same plane as the sheave, while the sheaves with the cable-trucl -supporting plates arranged only at one side of the recesses there 11, are adapted to deflect the cabie while maintaining the car-engagim arms on the cable attachments transverse to the planes of the sheaves.
