To all, whom it may concern.-

Be it known that I, AROHIBALD W. F. STEOKEL, a citizen of the United States, re-

siding at Columbus, in the county of Frank- I,

lin and State of Ohio, have invented certain new and useful Improvements in Car-Hauls, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in hauling apparatus of the sort more or less frequently used for propelling or controlling cars on grades, and comprising chains or cables with car-engaging attachments secured thereto, together with power-transmitting and guiding wheels for the chains or cables, and frequently comprising also structures which support the car-tracks as well as the shafting and wheels of the chains or cables and the guideways for the attachments.

The purposes aimed at and the mode of constructing and operating an apparatus embodying my improvements will be readily understood from the description below, together with the accompanying drawings.

Figure 1 is a plan view of an apparatus embodying my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transverse section on the line y y, Fig. 2. Fig. 4 is a side elevation of the parts shown in Fig. 3, the framework being shown in section. Fig. 5 shows a car on the uphaul. Fig. 6 illustrates a car on the downhaul. Fig. 7 shows a car in end elevation engaged by one of the car-engaging attachments. Fig. 8 is a side elevation of the cable-sheave and the parts associated therewith at the lower end of the haul.

In the drawings, A indicates a cable, this being the power-transmitting device to which the car-hauling attachments are secured. It is mounted upon wheels or sheaves to be described, suitably located in relation to the car-track.

To the cable are secured the car-engaging devices, which may be of any suitable and well-known type. For illustration, I have shown these car-engaging devices arranged in pairs, the devices of each pair being relatively close together. preferably carried by trucks having wheels B B. These trucks may be secured rigidly and detachably to the cable in any suitable These devices are position relative to the cable by means of a spring or any other suitable means and is free to swing downwardly toward the truck C in order to permit the engaging element on the car to enter between it and the standard or upright F of the front car-engaging device.

The upward movement of the pivoted dog M may be limited in any suitable manner so as to determine the normal position of the dog. The standard F extends up to the plane of the top of this dog when it is in its normal position.

As the construction and operation of carengaging devices of this class is well known and as the details of construction of the same are not apart of this invention, I have simply indicated the devices in the drawings Without showing their detail construction.

A track-supporting structure adapted to have my hauling device applied thereto is shown in the drawings.

T indicates a section of track which is approximately horizontal or slightly inclined downward and forward, T and upwardly-inclined section of track, and T an upper section which is approximately horizontal, these traclcsections at T T T being those over which the advancing or loaded cars are taken. The upper section at T may be adjacent to or may lead to a car tippling or emptying place. The empty cars are returned over the tracksections T T T, these being, respectively, parallel to those at T T, and T. The sections T T T T are laid up on a supporting structure U, formed of timbers or beams secured together in any suitable way. The cable A travels upward along the sections T T on a line between the rails constituting the track and then returns along the sections T T T At the lower end of the system the cable is supported on and runs around an idler-wheel A. This is mounted in a movable frame a, which is fitted to a stationary frame a.

a is a cable or similar flexible device connected to the wheel-frame a and passing over a sheave a and provided with a weight 0;. These latter devices maintain tension yieldingly on the cable. To receive this idlerwheel, the sliding frame, and the stationary frame therefor, a pit or chamber A below the track is provided. This is located at a suitable distance back from the track-supporting structure U U, and both the forward-moving leg of the cable and the returning-leg for a considerable distance in front of the idlerwheel A travel on lines inclined to the lines of the track-sections T and T this permitting the cable and its car-engaging attachments or trucks first to gradually approach the line of travel of the cars and afterward to gradually move away from the cars.

Vindioates the drive-wheel or power-transmitting wheel which propels the cable.

V is a guide-wheel or idler for the cable at the terminal of the uprun. W hen the cable reaches this wheel, it is turned downward therefrom to the driving-wheel V.

V is a guide-wheel or idler for the cable, over which it travels after leaving the drivingwheel V, and from which it passes to the guideway that follows the downtrack sections T T T. Preferably the drive-wheel V is situated relatively to the up going track and to the down going track in the way illustratedthat is, so that its pitch-circle is tangent to the vertical plane of the pitchcircle of the sheave V and to compensate for this the cable-wheel V is mounted at an in clination, as shown.

The cable-wheels are so related to the trackways and to the drive-wheel V that the trucks connected to the cable are in an upright position both while they are traveling up the one track and while they are traveling down the other.

W W indicate cars. With these the cable trucks or attachments can engage either by having the latter contact with the axles or by having the cars specially provided with arms, plates, or projections w. As the loaded cars one by one move along the bottom track-section T, each in turn reaches a position where one of the attachments or trucks on the cable moving forward from the idler-wheel A will engage it, such engagement occurring when the upright or standard F on one of the trucks contacts with the propelling projection to on the car. As soon as such engagement occurs the car is advanced by the cable and the attachment-truck up the inclined track-section T until it reaches the upper section at T Here the cable attachment leaves it and the car is free to move forward.

When an apparatus of this sort is employed for tippling or emptying the cars, they are allowed to descend from the point T over a gradually downward inclined track-section T to the tippling device. From that point they may be carried forward by gravity over a more sharply-descending track-section T,

and then after they are stopped in the usual manner and begin to return they may be switched over to the down going side of the track and guided to sections T T T. As the empty cars reach these latter sections they are again engaged with the cable and its attachments, the latter now serving as checking or controlling devices to retard them in their descent.

As above noted, the cable-trucks are still upright and are advancing in the same relative positions which they occupied when moving up on the tracks T T. Therefore the cars on the downgoing side are stopped by and rest against the rear sides of the standards F. If at any point a car in approaching one of the trucks should be moving with arelatively faster speed, its plate or projection to will first impinge upon the hingedog M, and the latter will yield under the im-' pact and permit the projection to pass it until it reaches a position between the dog M and the upright or standard F. If this should occur at a point where the car-track is level or is upward inclined forward, the dog M will instantly commence to bear against the rear side of the projection on the car and the latter will be advanced by this part M in such case instead of by the standard F; but if it should occur when the car and the truck are both moving downward, the car under gravity will advance or tend to advance and bear against the rear side of the standard F. l/Vhenever the dog M is thus depressed to permit the passage of the projection on the car which strikes it, the dog M immediately after the passing of the projection is again moved to its uppermost position. When the bottom of the inclined section T is reached, the car would tend to stop on the horizontal track-section T but now the dog M, which is behind the projection to, immediately engages with the latter and pushes the car along the horizontal part of the track to the place where the empty cars are to be finally delivered ready to be hauled away to the point to be again loaded.

At the place where the truck disengages from the returning empty car the guideway for the cable and cable-truck diverges downward, as above described, from the lines of the car-track toward the idler-wheel A, and the dog M is released from the projection w and from the car.

The wheels for the trucks or attachments are supported on and guided by a track having rails R B. These may be secured to timbers, as at R, or maybe fastened to or be parts of angle-rails, as shown at S,

It will be seen that the cable is so arranged, supported, and guided that that part which is uppermost when traveling along one of the pathways of the cars is also uppermost while it is traveling along the other pathway, this being in contradistinction from those construcr tions heretofore used or proposed which had endless draft devices traveling first along one car pathway and then along the other, together with car-engaging devices projecting therefrom, but which latter devices were either, as in some instances, so arranged as to be idle during one part of the travel of the draft device or idle in another part, or arranged, as in other instances, so as to swing on pivots from one operative position to another, so that they could engage with a car traveling first in one direction and then with a car traveling in the opposite direction.

The features of improvement in hauling apparatus which I have devised can be employed in mechanisms where bodies or articles other than cars are to be propelled or controlled.

The power for actuating the sheave V may be applied in any suitable manner. I have shown the said sheave rigidly secured to a horizontal shaft V mounted on bearings 12 o, the said shaft having secured to its inner end the spur-gear X.

w is a counter-shaft mounted in suitable bearings and having near one end the pinion X in mesh with the gear-wheel X and near the other end of the gear-wheel X 00 is another counter-shaft mounted in suitable bearings and having near one end apinion X arranged to mesh with the gear-wheel X and having rigidly secured to it near its other end a belt-wheel X to which power may be applied from any suitable source. In order to prevent this power-transmitting mechanism from reversing, and thereby permitting a reversal of the direction of travel of the cable A, I have provided on the shaft :0 a ratchetwheel Y, with the teeth of which engages a pawl Y, mounted on the framework of the system.

i It will be noted that I have mounted the sheave V in such manner that power may be easily applied thereto and that the powertransmitting mechanism may be relatively close to the ground, avoiding expensive framework construction and allowing that a simple system of power-transmitting mechanism may be employed. Furthermore, this arrangement of the sheave admits of a simple manner of directing the cable from the sheave V to the sheave V the axis of the latter being in a horizontal plane somewhat beneath the axis of the former. The construction possesses many advantages over those in which the cable is directed at its upper end by guiding devices in substantially a horizontal plane, as much more complicated power-transmitting mechanism is required in order to actuate such systems, and the horizontal or substantially horizontal mounting of all of the shafts in my construction furnishes a much simpler and considerably more durable mechanism than is obtainable in'those systems in which a number of vertically-arranged shafts have to be used in order to transmit the power.

It will furthermore be noted that I have done away with bevel-gears in the powertransmitting system, using only spur-gears, which, as is well known, is of considerable advantage in a power-transmission system in which the gearing is subjected to great and uneven strains and shocks. Furthermore, by directing the cable downward from the upper end of the tippling structure to a point near the ground the cable attachments are caused to pass every so often down about the sheave V near the ground, where they may be advantageously inspected by the operator and replaced when necessary.

Each of the cable attachments or car-engaging devices is separate from the other one of each cooperating pair of car-engaging devices and is detachable independently of the other one, so that in case one of the car-engaging devices wears more rapidly than the other it may be detached and replaced without discarding the other one.

Where the car-engaging elements are thus arranged in pairs, each pair may be considered as constituting a single traveling device for engaging a car and controlling its movements along both its forward and return paths of travel. It will be understood, however, that any well-known kind of car-engaging attachments may be employed suitable to an endless draft device arranged as herein shown and described.
