To all whom 'it may concern:

lie it known that l, llionAno C. SrANDL-iU, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new.

and useful Improvements in -TrackLaying Apparatus, of which the following is a specification.

This invention is directed to the provision is of an improved form oftrack-layinglappa ratus, whereby the tracks for railway trains may be laid rapidly and at considerably reduced expense.

The invention involves the provision of a truck adapted to run on the rails laid and carrying the apparatus which. is employed this including gaging devices for positioning the rails at the proper distance apart, means for lifting the ties into solid contact with the bottom surfaces of the rails spikeeholders for holding the spikes in position. pneumatic hammers for-driving; the spikes, and means for raising and lowering these hammers.

The pneumatic hammers 5 spike-holders to inoperative, position is 'ef- 'fected automatically as the hammers are lowered, this movement taking placeas soon into the ties far enough to hold them in position and re 4 sulting in moving: the holders to such posi tion that new spikes may be inserted therein While the ones formerly held thereby are being driven into positio llifting the ties against the rails is preferably includes cross of the truck and each having a pair of grablevers pivotally mounted thereon and adapted of the apparatus Will] the air. connections illustrated dis 7 are preferably. arranged for vertical movement in suitable The means for 2.0 of each holder preferred embodiment of my inven' devices; and Figs. at and 5 are detail views of the spike-holders andhammers.

Referring-to the drawiuigs the apparatus consists of a truck ha ting side-frames l and 2 connected by suitable cross-brnees-l, axles 'lnounted for rotation in suitable hearings formed in the side-frames. and wheels 5 on these axles. lfixtending across the truck and secured upon the side-frames, is a bolster or support e uponwhich most of the operating devices are mounted. lneunmtically-oper- 'ated hanuners Z of any suitable construction are mounted upon the support 6 and arrangedfor vertical movement thereoin this being done preferably by providing vertirally-disposed grooves in the support e; in which the hammers fit, and cover-plates 5:3 secured to the support 6 for maintaining the hammers in these grooves and guiding them in their vertical movement. Preferably a pair of hammers I is employed at each side of the'truck, so that two spikes for each rail may be driven simultaneously., one on either side of the rail, and these .two hannners are displaced somewhat in the direction of the length of the truck so that the two spikes are not directly opposite each other. The hammers of each pair are secured at their upper ends to a cross-head 9 connected by a link 10 to a lever ll which is pivotally mounted :upon a stez'idard 12 secured upon the support (3. The adjacent ends of the two lovers ll enter between collars 13 upon a piston-rod 14 on which is secured a piston adapted to reciprocate H1 a cylinder 15, this cylinder being mounted upon standards It? rising from the support 6. I

Mounted upon'the support 6 at each side of the truck are a pair of hearing-blocks l? .in which a shaft 18 is mounted for rotation.

Secured on this shaft are two spikeholders 19, which extend downwardly from shaft 18 and at their lower ends are provided with .ofi'set portions 20 adapted to entc'ndunder the hammers 7. In the .end of the portion I is it:VBItlCal-lY CllQPOSBd groove adapted to receive .a spike, and e Hate21' is pivotally mounted upon the end of each holder for retaining a spike in. the groove. this gate being pressed to theclosed position by a spring, so that when a spike has been-driven ashort distance into a tie adjacent thereto.

the holder can be moved from the operative position and the gate will turn on its hinge so as to release the spike. Theholders 19 aresecured upon shaft 18 by set-screws 22,

so that by loosening these screws the holders may be positioned at a greater or'less distance apart, to adapt the apparatus for use with rails having flanges of different widths.

head 27 is adapted to move vertically upon frame 25, being held in position by the guides 26. Pivotally mounted upon the cross-head 27 are two grab-levers 28. These '18\/ '8IS are in the form ofbell-cranks and at one end have a plurality of teeth formed opposite points.

thereon, as shown in Fig. 3. The other ends of the two levers 28 extend between collars 29 upon a piston-rod 30 having a piston thereon adaptedto. reciprocate in a cylinder 31 which is mounted upon the frame 25.

' The means for positioning the rails at the proper distance apart consists of two pairs of gage-arms, the arms of each pair being movable to cause their. ends to grip a rail between them and-move the same to the proper position. A. bracket 32 is secured to one side of the support 6 and is formed to provide bearings-for two short shafts 33. On one'end. of each of these shafts is secured a disk 34, .to which the gage-arms 35 and 36 are pivotally The end of the arm 35 is downwardl turned, so that the ends of the two arms are opposite each other and may grip a rail between them. To each of the isks 34 is secured aweight- 37 which when the disk 34 is released moves it in a direction to separate the endsof the arms 35 and 36.

Formed on eachof the disks 34 is a segmental gear 38, and these: gears mesh with .the teeth of racks formed on opposite sides of a piston-rod 39, the upper end of which carries a piston adapted to reciprocate in a cylinder 40 secured upon the support 6. A

, hanger 54 is pivotally connected at its lower end to each 0 the gage-arms 36, and in each of these hangers are two notches adapted to receive a pin on the end of an 'arm 55 projecting from the side-frame 2. When the hangers are in the position in which they are shown in Fig. 2, the gage-arms 35 and 36 are in the operative position. but by raising the hangers by means of the handles provided upon their upper ends, so that the pins on the arms 55 are received in the lower notches in the hangers, the gagearms 35,

connected at diametrically 36, willbe turned upon their pivots to carry the ends thereof to inoperative position.

Upon one end of the truck is a platform on which is secured an engine-driven aircompressor 41 and an equahzing tank 42,

and a pipe 43 leading from this tank supplies the air to all of' the pneumatical v operated devices. In Fig. 1, the piping to the various cylinders and the valves for controlling the various devices are shown diagrammatically. A pipe 44 branching from the pipe 43 supplies arr to either the upper or the lower end of the cylinder 15, a twoway valve 45 beingconnected in the pipe 44 by means of which either end ofcyhnder 15 may be connected to the supply-pipe 44 and the other-end connected to the exhaustport of the valve. A branch pipe 46 carries air from the pipe 43 to the upper end of the cylinder 40, and in this pipe 18 a valve 47 serving to permit or cut ofi the supply of air.' A pipe 48 carries air from the pipe 43 to a two-way valve 49, from which pipes 50 lead to the u per ends of the cylinders 31, and pipes 51 eadto the lower ends of those cylinders. It will be seen that by operating the valve 49, air may be permitted to flow from the supply-pipe 43 through the pipe 50 to theupper ends of cylinders 31 and exhausted from the lower ends through pipe 51 and the exhaust-port of the valve or may be supplied to the lower ends of cylinders 31 through pipe 51 and exhausted from the upper ends of the cylinders through pipe 50 and the exhaust-port of the valve. A. pipe 52 carries air to the pneumatically o erated hammers 7, and in this pipe is a doub e valve 53 by which the supply of air to either pair of hammers is controlled.

The operation of the apparatus willnow be described. When a pair of rails have been laid in approximate position upon the tles and the ends thereof connected by means of the fish-plates to the ends of the rails prevlously laid, the truck is run onto these rails a short distance. The gage-arms are then operated to position the two rails at the roper distance apart. This is'done by turnmg the valve 47 to the position for admitting air to the upper end of cylinder 40. whereby the piston of that cylinder is moved downwardly and the racks 39 thereof turn the disks 34 in a 'direction to bring the ends of the two pairs of gage-arms together upon opposite sides of a rail and move the two rails to the proper relative positions. The

valve 49 is then operated to admit air through pipe 50 to the upper ends of the cylinders 31 and exhaust it through pipe 51 from the lower ends of those cylinders,

so as to permit the cross-heads 27 and-the grab-levers 28 carried thereby to move vertically downward. Vl hen at the lower limit of this downward movement, the toothed ends of the levers 28 lie on opposite sides rocked in their bearings so' as to carry the holders 19 to inoperative position, in which then'operated to admit air to the lower. end I of cylinder and exhaust it from the upper end, thereby operating the levers 11 to move r they are shown in dotted lines in Fig, 4,
