METHOlI) OF FORMING RAILROAD-TRACKS.

SE'ESIFIGATION forming part of Letters Patent No. 758,524, dated April 26, 1904.

Application filed January 8, 1903- To all whom it may ooncerm' Be it known that 1, WILLIAM GroLDIE, a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have in vented a new and useful Improvement in Methods of Forming Railroad-Tracks; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the formation of railroad-tracks, its object being to provide for the cheap laying of new track to bring to exact gage or for the reinforcing of old track, such as where it is desired to stiffen the track by the employment of supportingbase-bars or bridge-pieces, or for bringing the track itself to perfect alinement or surface. In an application filed November 19, 1902, Serial No. 131,918, and in Patent No. 739,539, dated September 22, 1903, covering railroad-tracks and rail structures, one of the features described is the formation in the cross-ties of transversely-extending grooves or kerfs to receive either bridge-pieces placed under the rails at the joints or supporting base-bars extending continuously under the rails, such bridge-pieces or base-bars having longitudinally-depending supporting-ribs fitting into such grooves or kerfs in the ties or rails themselves provided with such longitudinally-supporting ribs formed under the flange.

The present invention relates to the laying of tracks embodying these improvements, as well as for laying tracks with the ordinary rails where it is desired to bring the track to more perfect surface, to accomplish this work cheaply, and to obtain a practically perfect gage or surfacing of the track.

To these ends my invention consists in cutting seats for the rail structures in the ties along the side of the rails by mechanism guided by the rail and seating the rails in the seats so formed in the ties, such as by shifting the ties or rails with relation to each other to bring such rail-seats under the rails and securing the rails to the ties.

It also consists in reinforcing the rails'by cutting such seats in the ties along the side of the rails by mechanism guided by the rails, placing reinforcing base-bars in the seats, and

then shifting the ties or rails to bring the Serial No. 138,266., (NomodelJ base-bars under the rails and securing the rails to the ties.

It also consists in certain other improvements which will be hereinafter set forth and claimed; 1

To enable others skilled in the art to practice my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure l is aperspective view showing the cutting of the seats in the ties. Fig. 2 is an end view illustrating the same. Fig. 3 is a perspective viewillustrating on one side the track with thebase-bars inserted in the seats soformed in the ties and on the other side the track having the rails shifted over the base-bars. Fig.- iis a perspective view illustrating the steps of laying the track with new rails. Fig. 5 illustrates the laying of bridgepiece, and Fig. 6 is a diagrammatical side view of car. 1 p I The invention is particularly applicable to use in providing for the reinforcement of track already laid where the rails are weaker than desirable, and instead of replacing the entire rail supporting base-bars are inserted between the rails and ties, as set forth in my application Serial No. 131,918, or for forming the seats to receive the bridge-pieces adapted to give special support to the joints of the rails, though it can be used in the laying of new track, such as for the employment'of rails of the character shown in said Letters Patent No. 739,539 or for forming more perfeet seats in the resurfacing or original laying ofthe ordinary rails. I will describe the invention particularly in connection with the reinforcing of the rails by means of the continuous base-bar, as set forth in the said application Serial No. 131,918, as this gives the best illustration of the invention. As set forth in said application, the ties 2 have seats 3, which preferably have grooves or kerfs 1 cut in their upper surfaces to receive the ribs 5 of the supporting base-bars 6 under the rails 7 and it is also desirable to bring the surfaces of the ties into proper shape to receive the supporting base-bar. As well known, in connection with track-laying it is desirable that the rails shall rest in certain position on the ties, the usual custom being to have about the same portion of the tie extending out on either side of the tracksay about a foot and a half beyond the railsthis being found advantageous in the supporting of the track and the distribution of the load from the rails over the ballast. In reinforcing the track in which the rails are all laid and in applying the supporting base-plate to track of that character it is therefore necessary to either shift the ties or the track itself to provide for the cutting of the seats in the ties. As the ties are seated in the ballast to maintain a solid road-bed, it is not desirable to disturb them further than necessary. I find the most desirable way to apply the invention is to unspike the rails and move them sidewise the desired distance and temporarily respike them to the ties. This can be easily accomplished, as the rails are coupled together. When this is done, the seats for the ties are thus exposed at the sides of the rails, one line of such seats outside of one rail and the other line between the rails and close to the outer rail. The ballast can be removed at one end of the ties and the ties moved under the rails, if desired. By any suitable apparatus guided by one or both rails the rail-seats are then cut in the ties, the seats being formed either of simple, smooth, plain, or cut seats for the rail-bases or for tie-plates, on which said rail-bases are to rest. or in addition to such seats providing kerfs cut in the ties for ribs either upon the rail structures themselves, as set forth in said Letters Patent No. 739,539, or on the supporting base-bars, as set forth in said application Serial No. 131,918. As the rail or rails acting as the guide are in the desired alinement, it is evident that the seats cut in the ties correspond to that alinement, and through the guidance of the rails the seats are formed in such position as to receive the rails or supporting base-bars of the rail structures and bring them into proper alinement. To accomplish this, in the use of the supporting base-bars such base-bars are set in the ties and the rails shifted back to their former positions or the ties shifted back under the rails, so that the base-bars will coincide in position with the rails, and when the rails are spiked to place the base-bars will hold the rails in proper alinement through the outer ribs 8, extending along the outer edges of the base-bars. To accomplish this, any suitable machinery guided by the rails may of course be employed. 1 have illustrated for this purpose a car 9, carrying rotating cutters 10 11, adapted to cut the ties along the sides of the rails. The car illustrated has the boiler 12 and the engine 13, from which connections are made in any suitable way, such as by the sprocket-chain 14, having clutch connections with the engine-shaft to one of the wheels 15 of the main truck of the car. I prefer to provide the car, as shown, with two trucks 16 and 17 and to form the car-body of two sections 18 and 19, pivoted together, as at 20, and to provide the main section 18 with a depending frame 21, carrying a grooved guidewheel 22, running on the track and forming the guide for the rotating cutters, so as to arrange to form the seats in proper alinement with the track. I prefer to employ only one such grooved guide-wheel 22 on the frame, the other supporting-wheel 23 of the frame 21 being plain-faced and simply acting as a support for the cutter close to the same to regulate the depth of cut of the seat or kerf formed in the tie by that cutter. By providing the car with the pivot it is evident that the main section 18 may through the guide-wheels 22 23 follow the course of the track, and so hold the cutters 1O 11 in proper alinement therewith during their cutting action. Power is carried by suitable chains or belting 24 25 to the shaft 26, carrying the cutters 10 11 and mounted to slide in the frame 21, the descent of the cutters in such frame being controlled by stops 27. Provision for the lateral adjustment of the shaft 26 with its cutters with relation to the frame 21 in any suitable way should also be made as set forth in the companion application, Serial No. 138,267. The cutters shown are adapted to out not only the kerfs 4 in the ties, but also to cut the railseats 3 in the surface thereof, the rotating cutters being provided with suitable knives 37 38 on its periphery for that purpose.

The preferable way to employ the invention and one suitable to the use of the apparatus above described is as follows: In order to provide for forming the permanent seat of the rails in perfect alinement, I first plane temporary seats therefor at the sides of the rails which are permanently spiked to the ties. For this purpose the ballast is cleared out of the course of the cutters and the rotating cutters are arranged to cut simple plain seats on the surface of the ties, the knives for cutting the kerfs being omitted. The ear is then passed over the track and through the rotating cutters cuts and planes the temporary seats on the surface of the ties at the sides of the regular permanent trackway and a proper distance from the same to provide for the shifting of the rails onto the temporary seats so provided. Such temporary seats thus provide a proper gage both as to the height of rail and Width of track for the quick shifting of the rails from their permanent seat to their temporary seats, and this can be quickly done by simply drawing the spikes, lifting the rails while coupled together, shifting them over to place, and spiking them in their temporary seats.

Where it is the object simply to plane new seats for the rails or for tie-plates to receive the rails without the employment either of the supporting base-bars above referred to or the rails having depending ribs above referred to, the car is then passed over the track, using the same cutters, the cutter-wheels being adjusted to cut the permanent seats in the ties the proper distance from the ends thereof and, if desired, directly in line with the positions of the rails before they were shifted. The rails can then be shifted back to place in the permanent seats so provided or onto tie-plates placed in such seats and spiked down.

If it is desired to employ either the supporting base-bars above described or rails having depending ribs, cutters provided with kerf-cutters are employed and through the apparatus above described the seats, with their kerfs extending below them, are formed in the ties. Where new rails provided With depending ribs are to be used, they are then seated in the seats so provided and coupled together and spiked to place and the old rails removed. When supporting base-bars such as above described are employed, the basebars are seated in the seats so provided and the regular rails are then shifted from their temporary seats over the base-bars and with the outer edges of their flanges bearing against the shoulders of the base-bars and are spiked to place.

Where it is desired simply to form seats for the rail-joints above referred to, the simplest way is to shift the ties under the rail-joints to the side of the track and through the apparatus above described cut the seats in the kerfs for the same in the two ties to receive the bridge-pieces, place the bridge-pieces in the seats so provided, and shift them under the rails and secure them in place.

In anyof the above operations it is evident that the cutting of the seats or seats and kerfs in the ties is done accurately and perfectly through the guidance of the cutting mechanism by the rails, either one set of rails or both, as desired, and that practically perfect alinement both as to kerf and track and height of the rail as seated and secured to the track may be obtained, the method described providing a very simple and eflicient way of changing the track without great manual labor and making it practicable to reinforce weak track or to supplement the track cheaply and quickly. In any such uses of the invention the advantages of the guideway of the rails themselves are obtained, and especially in connection with the reinforcing of the weak track or the supplementing of any track with the supporting base-bars the work can be quickly and cheaply accomplished.

The invention of course covers any modifications thereof, including its general principle.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The method of laying railroad-tracks,consisting in cutting seats for the rail structures in the ties along the sides of the rails and through the guidance of the rails and bringing the parts into proper alinement and securing the rail structures in the seats so formed in the ties.

2. The method of laying railroad-tracks, consisting in shifting the rails or ties sidewise with relation to each other, cutting seats for the rail structures for the ties along the sides of the rails and through the guidance of the rails, and then shifting the rails or ties with relation to each other to bring the rail-seats under the rail structures, and securing the rail structures to the ties.

3. The method of laying railroadtracks,consisting in cutting temporary seats in the ties along the sides .of the rails and through the guidance of the rails, shifting the rails onto the temporary seats so provided on the ties, and then cutting permanent seats for the rails through the guidance of the rails in their temporary position and bringing the rails to their permanent seats and securing them to the ties.

4:. The method of laying railroad-tracks, consisting in cutting seats for rail structures in the ties along the sides of the rails and through the guidance of the rails, then placing reinforcing base-bars in the seats and then shifting the rails or ties with relation to each other to bring the base-bars under the rails and securing the rails to the ties.

In testimony whereof I, he said WILLIAM GOLDIE, have hereunto set my hand.
