tains to make and use the same.

My invention relates to improvements in rail spiking machines adapted for spiking ties in rapid succession.

An important object ofthis invention is to provide aspik'e driving machine having novel means for supporting the spikes prior to and while being driven into the tie.

A further object is to provide a spike driving machine having means for spacing the spike holding members on opposite sides of the rails when passing the fish plates or other lateral projections.

A further object is to provide means for supporting and operating the driving members whereby the spikes on one or both sides of the tie may be driven home separately or simultaneously.

A further object is to provide a spike driving machine having means for adjustably and rigidly supporting the spike driving hammers whereby the same may be readily adjusted for spiking difl'erent width rails.

A further object is to provide a rail spiking machine which is of highly simplified construction, durable in use and which may be operated with a minimum of'attendant labor.

Other objects and advantages of the invention will be apparent during the course of the following description.

Fig. 8 is a fragmentary sectional view on line through theupper portion of one of the cyl-. ll'lClGIS, the view illustrating the exhaust port of thesame, and

Fig. 9-is a'fragmentary view of a spike supplying tube and associated element.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 designates a truck or car rotatably mounted The wheels operate on a track including rails 12 and ties 13. A hammer supporting and operating structure generally designated by the numeral 1 1 is mounted at one end of the truck and includes independently operated members arranged above each rail. Each ham-v mer supporting and operating structure includes a pair of spaced vertical guides-.15

having attaching brackets 16 extended therefrom and secured to the truck or car by bolts reciprocatory piston 18 is mounted within the cylinder 16 and is provided with a vertical depending piston rod 19 having connection with a head 20 slidably mounted between the guides 15.

As indicatedin Fig. 2 the vertical edge portions21 of the guides 15 extend about the front andrear edges of the head 20 and thereby prevent undue movement of the head.

A valve chest 22 is carried by the cylinder 16 and is provided with avalve 23 adapted for supplying fluid pressure to both sides of the piston whereby the same may-be elevated and lowered as desired, .A manu ally controlled lever 24 has connection with the valve and is adapted for controlling the position of the same. -A segmental rack 25 carried by the valve chest is adapted to be engaged by a dog 26 carried by the lever 24 for locking the lever in an adjusted position. A fluid pressure supply pipe 27 is adapted for supplying fluid pressure to the valve chest from where. it is conveyedto either side of the cylinder. A'pair. of coil of the guides and are disposed on opposite sides of the piston rod 19 for cushioning.

7 one of their sides inclined outwardly as indicated at 33 'forcontacting with the inclined sides 31 of the grooves. The top of the hammers flatly abut the top walls of the grooves, whereby upon engaging'the spikes the full force of theimpact will be transmitted to the heads. Theincline'd sides 31 and prevent the loosening of the hammers i strain.

within the grooves as the result of lateral Transversely extending adjusting screws 3i have'threaded engagement with .the upper portions 32 of the hammers and are adapted to be rotated for adjusting the hammers laterally. The heads 35 of each bolt are mounted within oval shaped recesses 36 in the head. Annular shoulders 37 are formed on the screw bolt 34 at points spaced from the heads 35 and form annular recesses in which retaining washers 38 are partially received for preventing lbn'gitudi na l movement of the screw bolts. The retaining washers 38 are held in position by locking screws 39. Set screws 40 have threaded engagement with the sides of the heads and engage the sides of the hammers forlocking the same in adjusted position and have their heads mounted iii-recesses 41.

Spike supporting members generally designated by the numeral 42' are clearly shown in'Figs. 6 and 7' and are arranged on each side of the rails one'slightly in advance of the other. Eac'h'spike supporti-ng member inchldes a pair of casings 43' arranged in endwise relation and having their adjacent ends open for the reception of the shank portions 43-3 ofj'aw's' la. The casings are rigidly connected by anrintennediate plate 4A5 which is oflsetat its" endsto dispose its centralportion outwardly Plates 46 are detachably secured to the inner sides of the casings 43 by bolts 4'7. The jaws are settog'ether by coil s rings 48 arranged within the casing and are limited in their forward movement by transverse stops: or bolts '49 extending through elongated slots 50 provided in the shank portions 43' of the jaws. Thej aws areprovided adjacent their spike engaging ends with inwardlyiexten'ding offsets 51 which d-isposethe' spike-engaging portions 52 directly'below' the-hammers.

The adjacent ends of the jaws are provided with recesses. forming openings in which the spikes 53 are received. The upper faces 54 of the adjacent end portions of the jaws are inclined downwardly to serve as guides for the spikes and also to be squarely engaged by the inclined lower end portions 55 of the hammers which serve to push the jaws outwardly upon engaging the same.

The spike supporting members suspended from arms 56 having attaching plates 57 secured to the connecting plates 45 by bolts 58. The upper ends of the" arms are; provided with inwardly directed sleeves-59 provided with rectangular openings slidablyr eceiving'a uared shaft 60. The shaft 60 is suspended rom brackets 61 secured to the truck by bolts 62. v Collars 63 are mounted on the squared shaft 60' and are adapted for limiting the inwardmovement of the sleeves 59'. Set screws 64 securely retain the collars in a set position.

Apertured ears 65 are" carried by the sleeves59 and are connected to the ends of a contractile coil spring 66 adapted for re taining the sleeves in contact with the col-- lars 63' whereby the spike supporting members are normally retained in their" innermost positions.

Links 6? are pivotally connected to the sides of the sleeves and have their upper ends pivotally connected to a vertically movable pedal 63 which is extended through the bottom of the truck and guide plates 69. A pivoted level 70 is arranged in contact with the upper portion ot the pedal and is adapted to be operated fordepressing the same. Upon the spike supporting members approaching the fish plates of the rails or other lateral projections, the pedal 68 may be depressed and the pairsof spike engaging members thereby caused to separate-. Immediately upon removing the pressure from the pedal 68, the spike supporting members assume their normal inward position di'rectlybel'o'w the hammers. Spike supplying tubes 7O are carried by the truck and adapted for supplying the spikes to the recesseswithin the jaws. The spikes are fed manually tothe tubes as each tie is aboutto bespike'd. As illustrated in Fig. S'the lower portion of each spike supplying tube is provided with a hinged section 71 adapted to be swung outwardly'upon being engaged by the head. 20 on itsdoe nward movem'ent. Shoulders 72 are carried by the adjacent ends of the spout 70 and the section -71 and serve to limit the inward swinging movement of the section 71. Arms 73 extend ing inwardly from the section 71- and the spout 70 are connected'byacoil spring 74 which serves to normally retain the section 71 in arlinement with the spout;

In: operation the spike driving. and supporting mechanism is arranged directly spike driving operating, the fluid pressure supply, is reversed and the fluid pressure supplied to .the under side of the pistons whereby the hammers are elevated, preparatory to spiking the next tie.

While I have shown and described the preferred embodiment of my'invention, it

is understood that such minor changes in arrangement andconstruction of parts may be made as Wlll remain within the spirit of the invention and the scope of. the appended claims.
