SINGLE-RAIL SPIKE DRIVING AND DRAWING MACHINE.

Specification of Letters Patent.

Patented June 26, 191%.

Application filed April 7, 1916. Serial No. 89,737.

To all whom it may concern:

Be it known that I, WILLIAM B. HALLI- WELL, a citizen of the United States, residing at Saugatuck, county of F airfield, State of Connecticut, have invented an I1nprovement in Single-Rail Spike Driving and Drawing Machines, of which the following is a specification.

This invention has for its object to provide a light, durable, efiicient, and relatively inexpensive machine for driving and drawing screw threaded spikes and for rotating tools, that will travel upon a single rail, can be placed on or removed from the rail by one man, is so compact that it will lie between tracks and permit trains to pass, thus avoiding lifting of the machine over tracks, and which with one man will drive or draw quite a number of spikes in the time required by two men to drive or draw one spike by hand.

With these and other objects in view, I have devised the novel spike driving and drawing machine which I will now describe, referring to the accompanying drawings forming a part of this specification and using reference characters to indicate the several parts Figure 1 is a plan view of my novel machine, as in use; i a

Fig. 2 is a side elevationcorresponding therewith;

Fig. 3 a section on the line 3-3 in Fig. 2, looking down upon the carriage;

Fig. 4 a section on an enlarged scale on the line 4.& in Fig. 1, looking in the direction of the arrows;

Fig. 5 a detail sectional view: on an enlargedscale on the line 5-5 in Fig; 3, and

Fig. 6 is a section onthe line 66 in Fig. 3, looking in the direction of the arrows.

l0 denotes the carriage which is formed from sheet metal and is shown as having an inverted U shape in cross section. A bed 11 is pivoted to the carriage as at 12, to swing in thehorizontal plane. The pivot pin is relatively'long and passes through thickened washers 13 above and below the bed and carriage respectively, so as to insure a rigid pivotal connection. The swinging bed comprises a plate l t and U shaped strips 15 riveted thereto. 16 denotes an engine or motor, the base of whlch 1s bolted to strips 15. It is of course wholly immaterial, so far as the present invention is concerned, what type of engine or motor is used, it beof sheet metal.

V20 denotes a handle by which the machine is propelled and lifted and which is simply a piece of tubing bent to the required shape. The handle is secured in place by passing the arms thereof through eyes 21 011 opposite sides of the carriage, at the rear end, the ends of the arms being seated in sockets 22 which are rigidly secured to the axle. 23 denotes inwardly turned ears which depend from opposite sides of the carriage at the ends thereof. 26L denotes rail-engaging double flanged wheels which are journaled between the ears of the respective pairs and are adapted to travel tandem upon a track rail indlcated by 25. The axleis appreciably longer than the width of the carriage and carries supporting wheels 26 which keep the machine in balance and are adapted to travel on the ties and road-bed of the track on opposite sides'of either rail of the track while it is engaged by the flanged wheels, one rail only being shown. 28 denotes a housing rotatable in the vertical plane and having trunnions 29 and 30 which are journaled in bearings upon standards 31 riveted to the swinging bed. l/Vithin the housing is .a bevel gear wheel 32 having hubs which are journaled in hearings in the housing. 33 denotes a chuck shaft, passing through the housing transversely, upon which the gear wheel is mounted with a spline and groove connection, leaving the shaft free to slide longitudinally relatively to the gear wheel, which imparts rotation to the shaft. Each end of shaft 33 is provided with a chuck 34 which is adapted to engage the head of a spike or the shank of a drill or other tool. Driving shaft 17 is mounted to rotate in trunnion 29 and carries a bevel. gear wheel 35, within the housing, which meshes with gear wheel 32. A half rotation of the housing in either direction will of course change ends with the chuck shaft, so that one chuck will turn spikes or a drill in e a Ox.

and the other chuck will turn them out. The spikes used, as 36, are threaded and are provided with angular heads adapted to be engaged by the chucks. swung on its pivot, so as to place the shaft oneither side of the rail, as indicated in Fig. 1. The swinging bed is locked in the central or in either of its operative positions by means of aspring bolt 37, within a case 38, which is riveted to plate 11- of the bed and is adapted to engage either of three holes 39 (two only being shown) in the carriage. The chuck shaft slides freely through gear wheel 32 and the operator raises 0r lowers it as required, by means of a hand lever 40 pivoted to a link 41 which in turn is pivoted to the engine or motor. This hand lever carries a block 42 which is provided with a socket to receive either of the chucks and with a bevel nosed latch 43 which is adapted to engage the under side of a chuck. A spring 44 acts to retain the latch in the engaging position, the latch being released to disengage the chuck by means of a rod 45 extending to a grip 46 pivoted to the hand lever. lVhen the hand lever is swung downward, the beveled nose of the latch will engage the top of the chuck and force the latch outward against the power of the spring. As soon as the latch has passed the chuck, the spring will throw it to the engaging position again, as in Fig. 4, so that the chuck shaft may be raised or pressed downward by means of the hand lever.

The operation is as follows: The machine as a whole is so light that it may be readily lifted off or on .a rail by one man, and moved in either direction, the flanged wheels traveling on the rail and the supporting wheels keeping the machine in balance and traveling upon the road-bed and ties on opposite sides of the rail that is being spiked, Themachine furthermore is so compact that it may be left between tracks without danger of contact with passing trains. For example, to avoid a train 011 the track to which the rail being spiked belongs, the machine might be lifted off on the outer side, or if this was not practicable, it might be lifted over the other rail and left between the tracks, and if trains should pass on contiguous tracks while the machine is between them, no harm would be done. It is an important advantage of my novel machine that, on account of its compactness, it merely has to be lifted off the track upon which a train is coming but does not have to be lifted over other tracks.

Fig. 2 in connection with Fig. 1 illustrates clearly the operation of driving or drawing a spike, the operation being of course the same if a drill or other tool is used. The engine or motor may be kept continuously in operation while the machine is in use. The

The bed may be' ing machine is placed in position by simply moving it along-the rail, one of the chucks is placed in engagement with the head of a spike toeither driye or draw it, and the clutch lever is operated to connect the driving shaft with the engine or motor. The operation of driving or drawing a spike or of drilling ahole' is practically instantaneous. The clutch lever is then operated to disconnect the driving shaft from the engine or motor and the machine is moved into position to drill another hole or to drive or draw another spike.

Having thus described my invention, I claim:
