SPIKE.
SPECIFICATION forming part of Letters Patent No. 791,373, dated May 30, 1905.
Application filed February 7, 1905. Serial N- 244,565
To all whom it may concern.-
Be it known that I, CLARENCE SHAFFER, a citizen of the United States, residing at Clearfield, in the county of Clearfield, State of Pennsylvania, have invented certain new .and useful Improvements in Spikes; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.
This invention relates to spikes in general, and more particularly to the class of railwayspikes suc as are em loyed forholding railway-rails to the ties, t e object of the invention being to provide a spike having lockingbarbs which are adjustable into and out of position to engage in the tie' and prevent withdrawal of the spike.
A further object of the invention is to provide such an arrangement as will permit of withdrawal of the barb into the body of the spike when it is desired to remove the spike.
In the drawings forming a ortion of this specification, an in which li re numerals of reference indicate similar arts in the several views, Figure l'is a side e evation showing a spike embodying the present invention. Fig.
"2 is a section taken longitudinally through the s ike with the barbs projected, parts being s own in elevation. Fig. 3 is anelevation of one of the barbs. view of the nut.
Referring now to the drawings, there is shown a spike includin a body 5, having at its upper end the usualliead 6, the lower end of the body being pointed, as shown as 7, so that it may be driven into the tie. In the lower ortion of the bod 5 is a chamber 8, from t e u per end of w 'ch there lead passages 9 an 10 upwardly through the sides of the body 5, and midway between these passages is a central passage 11, that extends Fig. 4 is a top plan from the chamber 8 upwardly and through the head of the spike. In the assage 11 is disposed a screw which rotates oosely in the passage and the lower threaded portion of which enters the chamber 8. The screw is illustrated at 12 and com rises a head 13, which enters the counters nk 14 at the u per end of the passage 11. The head of t e the nut is moved vertically in the chamber.
At op osite sides of the nut 15 are notches 16, whic receive the reduced necks 17 at the lower ends of barbs or fingers 18, which are tapered upwardly. The barbs or fingers are of such dimensions that they may lie entirely within the body of the spike, with their upper or pointed ends against the u perwalls of the corresponding passages 9 an 10. When the nut 15 is moved upwardly, the barbs or fingers are raised, so that their upper ends project from the body of the spike and by engagement in the tie serve to prevent withdrawal of the spike. When it is desired to withdraw the spike, the nut is fed downwardly by correspondingly rotating the screw, as will be understood. The heads at the lower ends of the barbs, which result from reducing the barbs in the formation of the necks 17, revent upward disen agement of the barbs rom the nut, while t e bodies of the barbs themselves prevent downward disengagement.
What is claimed is A spike comprising a body and a head, said body having a chamber in its lower portion, a central longitudinal passage leading from the chamber through the head of the s ike and side passages leading from the chamber and upwardly and outwardly through the sides of the spike, barbs disposed with their'lower portions in the chamber and having their upper ends sharpened and disposed in the side passages, a nut in the chamber with which the barbs are connected, and a feed-screw passed through the central passage into the chamber and engaged with the nut.
In testimony whereof I afiix my signature in presence of two witnesses.
CLARENCE SHAFFER.
