LOG HAULING AND LOADING MACHINE.

SELTGZ'EKGATION forming part of Letters Patent No. 726,325, dated April 28, 1903.

Application filed July 17.1901. T

To (tZZ whom it may concern.-

Be it known that we, THOMAS SPENCER MIL- LEE, of South Orange, in the county of Essex and State of New Jersey, and JOSEPH H. DICKINSON, of Atlanta, in the county of Ful ton and Stateof Georgia, haveinvented a new and Improved Log Hauling and Loading Machine, of which the followingis a full, clear, and exact description.

Our invention relates to an improved device for hauling and loading logs upon cars, and comprises the features which will be hereinafterdescribed, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of our device, showing the position of the cars relative thereto while being loaded. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation, which also shows a car. Figs. 4 and 5 are details of the Suspender of the sheave-blocks from the hauling-boom.

The device herein shown is designed to be moved from point to point along the track and to both haul the logs to the track from points at considerable distance on either side and to load the logs upon the car after they have been delivered alongside the track.

The form of device as shown is the form now preferred by us, yet we are aware that many of the features thereof may be materially changed in detail without departing from the spirit of our invention. life do not, therefore, wish to be limited to the exact construction herein shown.

The device is mounted upon a platform or frame A of any suitable construction which will give suthcient space and strength to hold the machinery and be carried when in use by supports at each side of the track, su fliciently separated to permit passage of cars between them. Upon this platform is mounted the hoisting or hauling engines necessary to work the required lines and a boiler or boilers to furnish steam for them. Two engines E and Serial No. 68,594- No model.)

F are herein shown, each engine having plural drums and a single boiler Q to furnish steam for both engines. Near one end of this platform is a mast M, which is herein the strains produced by the two booms, which are supported thereby. A boom B is pivotally supported by pivotsb at its lower end from the platform, so as to swing in a vertical plane, the boom being shown in the form of shearlcgs for much the same reason as those given for the mast. The upper end of this boom is supported by a rope G, which is rove through blocks g and 9 secured, respectively, to the boom and to the mast, and then through a guide-block g to a drum 6 of the engine E. The ability to raise and lower this boom by power gives us an efiective and convenient means for tightening the guys by which the side strains of hauling are taken up. The boom B, which is used for hauling in the logs from a distance, we call a hauling-boom. Suspended from the upper end of this boom by a spring-link I are two blocks or pulleys 7t and it, through which the hauling-ropes H and H pass. These ropes extend from the drums e and e out in the direction from which the logs are for the time being taken. These ropes are ordinarily taken out to the log by a horse, although an overhauling-rope or other power-operated device may be used for this purpose, if desired.

The connection between the sheaves h h and the boom is preferably a yielding one, so that if a log being hauled should catch hard upon anythingit would relieve the shock upon the boom. The means adopted for securing this result is shown in detail in Figs. 4 and o. The connecting member I therein shown constitutes a spring-link consisting of the two clevises t and i, which lie in planes at right angles, and the spring 7?, which lies between the sides of both clevises and is connected withthe ends thereof by suitable plates or bars, so that the spring is put in compression by a strain upon the device. One clevis is connected with a link or attaching member 19 secured to the boom, and the other supports the guide-sheaves h h, To prevent direct striking of the blocks or sheaves h and h, a pad 71 is interposed, which softens the jar and is sufficient to often prevent breakage. This pad may be a simple sheet of leather or may be a pad of more complicated construction.

The engine F, which is used for operating the hoisting-boom D, is mounted upon aturntable F, and the hoisting-boom D is pivoted at d upon the forward edge of the same turntable. The turn-table pivot is located forward of the shear-legs M, which constitute the mast, and the hoisting-boom pivot on the forwardside of the turn-table, which throws the boom-pivot sufficiently forward of the mast M to enable the hoisting-boom to be swung very far to one side without being interfered with by the mast. In other words, its arc of operation is thereby increased. The engine has a main hoisting-drum f, which receives thehoisting-line L, said line passing over a sheave L, carried by the outer end of the boom. The engine F also has two drums f and f which carry the boom swinging ropes N and N, said ropes leading from the drums directly through sheaves n and 'n at the outer end of the boom and then laterally to convenient anchorages, so that by wind-.

ing in on one rope and paying out the other the boom may be swung and held as desired.

The outer end of the hoisting-boom D is supported by a guy D, which leads to the top of the mast M. Preferably this is made of a section of wire cable.

The platform A, upon which the entire mechanism is mounted, is moved from place to place along the line upon a car. When it reaches a point where it is desired to use it, it is raised, so as to clear the car, and its Weight transferred to supports at the side of the car, so that its supporting-car may be removed and the logging-cars run through beneath the platform.

In previous devices of a similar character legs or equivalent devices of constant length have been used for this purpose; but if the bearings of any of these legs happen to be on softer ground than others the settlement caused by the weight is unequal and the platform is twisted, and it is often necessary to let the weight back upon the car and build up additionally under some of the legs. Each adjustment of this sort consumes considerable time, and therefore defeats the object sought to be obtained by such devices as this. To avoid this, we have made our supports independently adjustable and capable of readjustment at any time after setting without disturbing the working of the device. This has been done byinserting in each supporta jack or equivalent device by which the platform may be raised from the car and by then inserting blocking as needed. As the device is herein shown, a longitudinal beam 0. is placed beneath each side of the platform, and to this are secured blocks a at each end of the platform. The jack J is placed between the blocks a and bears upon temporary blocking C, of any convenient charactexysaid blocking 0 resting either upon the ties or the ground, as most convenient.

The engine E, in addition to the drums for the hauling-ropes and the boom-hoisting rope, has a drum e carrying a rope O, which leads over a sheave O' and thence beneath the platform to a connection with one of the cars to be loaded. By this meansthe cars may be moved up to their loading position, and the services of a locomotive and the train-crew may be dispensed with while loading.

The operation of our device is as follows: It is brought to the point on the track where it is to be used loaded upon a car. When the desired point is reached, the foundation-timbers O are put in place beneath the edges of the platform and outside the car and brought to approximately the height desired. The jacks J are then put in place upon the foundation-timbers O and beneath the beams 01,. The platform is then raised by the jacks until it is entirely supported upon the jacks and the car is cleared, so that it may be run out from beneath the platform. This leaves an opening beneath the platform sufiicient to permit the logging-cars being run through. The string of logging-cars is then run through beneath the platform or to the end opposite the loading-boom. Blocks or wedges as necessary to make a firm bearing may be inserted between the foundation-timbers C and the blocks a, if desired. The weight of the device may be entirely or partially carried in this way by slacking back the jacks, if desired. When the device has been securely set in position, the hauling-ropes H H are run out laterally from the track and the guys K K extended laterally and secured to con- Venient anchorages. The swinging-ropes N N are also secured to anchorages. Theguys K K are tightened by raising the boom B, the boom being in a lowered position while the guys are being secured to their anchorages. The device is then ready for operation. The logs are brought in to the side of the track by the ropes H H and are then taken by the loading-boom and placed upon the cars, one of which is shown as partly loaded in Fig. 1. Then a car has been loaded, the rope O, which extends from the drum a over sheave 0, to the rear of the platform and is attached to one of the cars, is wound in, thus pushing the cars along until another car is beneath the loading-boom. In this way the cars are successively moved up and loaded, the services of a locomotive and a traincrew not being needed for this purpose.

The various drums of the engines are operated by friction devices and controlled by brakes after the manner usual in engines of this character.

By means of the drum (2 and the rope G the hauling-boom may be raised when desired, with the result that the'guys K K,

- which take the side strain of the hauling-ropes H II, may be thus tightened by power. At the same time the sheaves 71 h, which guide the hauling-ropes, are swung beneath the end of the hauling-boom by a link consisting of the device I, which permits them to swing to one side or the other, according to the strain upon the ropes and their length, thus taking all side strain from the boom and transferring it to the guy-ropes. This feature, which is of considerable importance, enables the boom to be securely fixed to the platform and relieves the platform and boom of all side strain. It thus needs only be strong enough to support the end strain produced by the ropes.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent I 1.
