TRACK-LAYING MACHINE.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed May 20, 1909. Serial No. 497,270.

.To all whom it may concern:

Be it known that I, JOHN R.' MCGIFFERT, a citizen of the United States, and a resident of Duluth, county of St. Louis, and State of Minnesota, have invented a new and useful Improvement in Track-Laying Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

As is well known, machines have been used more or less in railway construction work in order to facilitate or render possible the more rapid laying of the track by providing means for depositing the ties and rails, whereof said track is constructed, approximately in the place where they are to lie. The present invention belongs to this general class of machines, being particularly designed, however, for use in connection with the laying down and taking up of sectional track, that is, track where the rails and ties are already assembled, the former being spiked onto the latter so as to form sections approximately equal in length to that of the rails. Track thus constructed is largely used, for example, in connection with logging operations, it being customary in such operations to run a main line, more or less permanent, through the timber, and from this main line to extend temporary spurs or lateral branches. Such branches are run out on both sides of the main line at intervals of from six hundred feet to onehalf mile, depending on the density of the timber and other circumstances. As these spurs or branches are used only for the transportation of the logs which are adjacent to them, they are very temporary in their character, they are frequently taken up and relayed every thirty or forty days. It will, accordingly, be seen that three or four spurs are all that are ordinarily required to be in use at one time, so that a comparatively small quantity of rail and ties suilices for the branch lines, each spur being taken up as soon as it is no longer needed and placed in a new location. This, however, necessitates the very frequent taking up and relaying of the tracks, and it is for this operation that the invention in hand is particularly designed, as has been indicated.

Said invention then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanlsm embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings Figure l is a side view of a track laying machine embodying my several improvements along with various accessory parts; Fig. 2 is an end view of one of the cars forming a part of said machine; Fig. 3, is a side elevation on a larger scale of the other of said cars whereon is carried the winding mechanism of the machine; F 1g. t is a plan view of such last-named car; and Fig. 5 is a sectional view of a detail taken on the line 5-5, Fig. 3.

Referring first to Fig. 1, my improved machine will be seen to comprise in general, two special cars A and B, respectively provided with masts A and B', between which latter is supported an extensible trolley line C forming a cableway, whereby a variable number of ordinary freight or logging cars D may be coupled between said masted cars. These intermediate cars are designed to carry the sections E of track that are either being laid in place on the road bed, or removed therefrom for transportation to another site, a carriage C movable along cableway C being utilized in the handling of such track sections.

Of the two special cars A and B, the foremost one comprises an ordinary flat bed a that forms a base upon which is mounted the mast A, said mast comprising two forwardly inclining side frames a that are connected at their outer ends, only so as to leave ample space between the sides for the passage therethrough of a section of the track, as is necessary in the operation of the machine. A single sheave a2 is mounted in the forward upper end of said inclined mast,-

around which passes a cable o for drawing the carriage C forwardly on the cableway from which the carriage is suspended, the forward end of said line being xedly attached to the peak of said mast at a3.'

The rearmost car B is a self-propelling car upon which, as has been previously stated, I mount the operating mechanism of the machine, consisting particularly of three winding drums, b, b2 and b3, and a suitable engine b for operating the same. The inner end of the trolley line C is connected with the rearmost b of said three drums, said line passing thence over a sheave b4 in the upper end of the mast B of the rear car to its point of attachment a3 on the foremost mast A. Mast B is preferably in the form of an A-frame and is held in a vertical position by means of guy lines b5 extending from its top to the corners of the bed or frame 5G of the car. By Winding in more or less of trolley line C, the latter may be maintained in proper taut condition, irrespective of the distance between the two cars A B, or in other words, irrespective of the number of intermediate cars D that may be employed, as will be obvious. Of the two remaining drums, the one b2 received the inner end of the carriage-operating cable c presently referred to, such cable passing over a sheave [97 in the mast Bl of the rearmost car, (see Fig. 5), and around the sheave a2 in the forward mast to the front end of the carriage C where it is attached. The latter is somewhat elongated, and is provided near its respective ends with two sheaves c c2, over which pass the respective portions c2 of the bifurcated end of a second operating cable 03, the inner or rear end of which is attached to the remaining drum on the rearmost car passing` thence over a sheave bs located by the 'side of sheave 127 in mast B.

A Spanner c4 separates the respective portions of such bifurcated cable end o2, and, consisting preferably of a steel rail, has sutlicient weight to cause such end to descend Vwhen the tension is t-aken o of the cable by unwinding drum b3,the point of union 05 of the two portions being far enough to the rear of the carriage to prevent interference with the passage of the cable overthe sheaves c in the carriage.' To Spanner c4 in turn are attached crotch lines c that are provided at their lower extremities with tongs or grapples for attachment to the balls of the rails, as will be readily understood.

The engine is connected with drums b2 b3, so as to permit of their rotationin opposite directions when desired. Such operation is,

i Y moreover, had at approximately the same speed, so that the cable will be drawn olf the one at Vapproximately the same speed as it is wound onto the other. The effect of such operation of the drums, hence, will be Y to cause the carriage to Ymove Ybackwardly o r forwardly, along cableway C, depending upon the direction of rotation in which the drums are operatedfwithout either raising or lowering the load suspended from the outer bifurcated end of cable 03 andy without Vrequiring anyinhaul cable and the additional winding mechanism that would be required therefor. When it is desired, on the contrary, to raise or lower the carriage, outhaull cable c is drawn suiiciently taut, and its drum b2 held by brake or other suitable means, whereupon rotation of drum b3 will obviously be effective to raise or lower the outer weighted end of cable 03 depending upon the direction of rotation of said drum. Assuming, accordingly, that a track is being laid, such weighted cable end and carriage will be moved over one of the cars D upon which are located the track sections E employed in building the track. A section being grappled to the cable end, is thereupon raised a sufficient distance to clear the load, and by proper manipulation of the drums, the carriage is caused to travel to the forward end of the cableway, in which position the track section hangs clear both of the mast and the end car that supports the same, as shown in Fig. '1, and may thereupon be lowered into place. After such section has been suitably secured to the portion of the track already laid, the whole machine is advanced a corresponding distance, and another section brought up and dropped in place. In taking up track, the operation is the same, except that the order is reversed, the machine retreating a distance equal to the length of a track section, after each successive section has been taken up and stowed away on one of the intermediate cars.

In order to facilitate the frequent shifting of the machine thus seen to be necessary, rearmost car B is rendered self-propelling, by connecting shaft b with the trucks 121 of the car through suitable sprocket chains and sprockets bu. By simply throwing a clutch 512 on the end of said shaft, the machine may be advanced or retracted in the manner just described, or along with intermediate cars such machine may be propelled for greater distances, as in the transportation of a stock of the track sections from one location to another.

By. the foregoing construction, not only is the laying down and taking up of track rendered possible in an expeditious and eiicient manner, but no complicated hoisting or conveying mechanism is required. At the same time, a machine perfectly iexible and of easy manipulation is provided, and one furthermore that is capable of self-propulsion from one point to another, rendering it independent of locomotives or other power for which there is generally plenty of use elsewhere in connection with operations such as those under discussion. Lshould also call attention to the advantage of the particular construction of trolley carriage and of the manner in which the hoisting operating cable is connected therewith.

VSaid carriage being made of considerable suspended from the carriage is kept in alinement with the track and the cars, and is prevented from swinging around so as to become entangled with the mast of the forward car or with other obstructions, as it is passed backward or forward along the t-rain.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.
