SPIKE EXTRACTOBI.

Application filed March 19, 1925. Serial No. 16,804.

To all whom it may concern:

Be it known that 1, Jon RADr-R, a citizen of the United States, residing at Belva, in the county of Woodward and State of Oklahoma, have invented certain new and useful Improvements in Spike Extractors, of which the following is a specification, reference be ing had to the accompanying drawings.

This invention relates to spike extractors, and particularly to extractors which are used for pulling railroad spikes.

The object of the invention is to provide a very simple and strong device of this character so constructed that it may be readily placed bet-ween two adjacent rails and engaged with the spike and which is capable of being operated by an ordinary claw bar or similar tool which cannot be directly engaged with the spike.

A further object is to provide a device of this character which is so constructed that the claw bar may be disposed in a variety of radial relations to the axis of the spike extractor so that the claw bar may be fulcrumed upon adjacent rails, ties or the like without regard to the position of the spike.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of a spike puller constructed in accordance with my invention;

Figure 2 is an elevation partly in section;

Figure 3 is a sectional view through the adjacent rails of a switch showing my spike puller in position ready to pull a spike.

Referring to this drawing, it will be seen that my improved spike extractor comprlses a head 10 which at its lower end is formed with the two oppositely disposed claws 11 which are adapted to be forced beneath a spike by driving. From the upper end of the head extends the stem 12 ending in a head 13 and this is swiveled within the This lower end of the shank is enlarged, as at 14, to accommodate the head 13 and is contracted to form a neck 15 fitting against the neck of the head 10. The stem 12 extends up through the lower end of this shank and the head is disposed within a transverse passage 16 formed in the head 14. Above the head 14 the shank is enlarged, as at 17, then again reduced in diameter, and then again enlarged so as to form a head 18. These protuberances 17 and 18 are so designed that a crow bar or claw bar may be disposed to engage beneath either ofthe heads 17 or 18 and thus a lifting force applied to the spike extractor.

By reason of the fact that the head 10 with its claws is swiveled upon the shank 14, it follows that the lower portion of the device may be shifted into any desired relation and engaged with the spike to be extracted and the crow bar or claw bar may be disposed either parallel to the rails A or transversely of the rails A or in any other desired relation. It will be noted that the contracted necks between the heads 17 and 18 are cylindrical in form so that this permits the claw bar or crow bar to be disposed in any desired radial relation.

VVit-h this device spikes between switches and frogs may be removed by placing the claw bar between the rails, which is not possible where the spike-engaging claws are not swiveled to the shank.

This spike extractor is particularly adapted for reconstruction work, as it may be placed in engagement with the spike between switches and frogs and the claw bar can be placed in any position desired. This is permitted by the swiveled head of the rigid shank, which permits the upper portion of the spike extractor to be rotated with relation to the lower portion t may be used for pulling spikes on bridges outside of the rail by placing the claw bar alongside of the rail. This cannot be done with a spike extract-or which does not have a swiveled upper portion, as in this form of spike extractor when the extractor is applied on the outside of a bridge rail there is no way to stand to pull the spike as the claw bar will stick out beyond the bridge, and if the spike head pulls off the operator is very likely to fall. My spike extractor will allow the operator to place the claw bar in any position where it is most convenient by turning it with the swivel. It is not possible to turn the claw bar so as to pull spikes between the rails or on T-rail bridges with any other kind of spike extractor, as the spike extractor will not turn on the spike so that the claw bar may be placed on them.

I claim 1. A spike puller comprising a shank having a plurality of protuberant portions claw, the shank being cylindrical in cross along its length with which a claw may be section and being formed at intervals with engaged, the shank at its lower end being spherical protuberances. 10 provided with a swiveled head having a In testimony whereof I hereunto affix my 5 spike-engaging claw. signature.

2. A spike extractor comprising a shank provided atits lower end with a swiveled J OE RADER.
