FRANK GROSSER AND ERWIN H. GROSSER, OF EGELAND, NORTH DAKOTA.

RAILROAD-SPIKE.

Application filed November 1, 1916.

To all whom it may concern:

Be it known that we, FRANK Gnossnn and ERWIN H. Gnossnn, citizens of the United States, residing at Egeland, in the county of Towner and State of North Dakota, have invented certain new and useful Improvements in Railroad-Spikes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in railroad spikes.

An object of this invention is to provide a spike which is especially adapted for reliably securing railway rails to ties and prevent accidental withdrawal of the spike.

A further object of this invention is to provide a spike including an anchoring member, and an operating member for the anchoring member which will hold the spike against removal due to the vibration incident to trains traveling over the track.

A still further object of this invention is to so construct a spike and anchoring means that the same will readily anchor the spike to the tie and can be properly operated as the spike is driven home.

A still further object of this invention is to provide a spike of this character which will be simple, practical, and comparatively inexpensive in construction, and one that can be manufactured and sold at a comparatively small cost.

With these and other objects in view the invention consists in the novel combination and arrangement of parts hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a sectional view through the spike illustrating the anchoring pin and setting member in inoperative position.

Fig. 2 is a sectional view through the spike illustrating the manner which the anchoring member assumes when in an anchoring position.

Fig. 8 is a perspective view of the spike.

Fig. 1 is a perspective view of the anchoring pin setting member.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

Referring more particularly to the drawings, the numeral 1 designates the shank of the main spike having a head 2 pro]ect1ng laterally of the front face thereof at one Specification of Letters Patent.

end. The opposite end of the shank 1 is tapered to define a cutting edge 3 and the front face of the shank is provided with a longitudinally extending groove.

The side walls of the longitudinally extending groove 4 prevents shifting movement of the anchoring member when arranged therein, the lower end of the groove terminates into a transversely arranged recess 5, the rear of which is provided with a longitudinal opening 6, which commui'iicates with the recess, as illustrated in Fig. 3 of the drawings.

The opening 6 is located at a point above the cutting edge 3 and is provided adjacent its upper end with transversely arranged openings 7 through which is adapted to extend a pivot pin 8. The pivot pin 8 has journaled thereon an anchoring member 9 which has its lower end spaced from the bottom wall of the opening 6 as clearly shown in Fig. 1 of the drawings.

The anchoring member or threading device is designated generally by the numeral 10 and it comprises a shank 11 having a head at one end thereof designated 12. The opposite end of the shank 11 is enlarged laterally on opposite sides thereof as at 13. The shank 11 is slidably arranged in the longitudinal groove 4 and the lateral projecting portions are arranged in the recess 5. The lower end of the shank 11 is provided with a longitudinal opening 14, the upper wall of which is inclined as at 15 to normally force the lower end of the anchoring member 9 into engagement with the bottom wall of the opening 14, which is inclined to normally raise the spike into a horizontal position when the spike is driven in a tie.

In use:

The main spike and anchoring setting bar are assembled as shown in Figs, 1 and 2 of the drawings and the main spike is driven into a'tie or other object in the usual manner by blows delivered upon the head 2 thus forcing the spike into the object or tie until the head 12 of the anchoring setting memelor is in engagement with the object or the tie. Thus it will be seen that the bar or shank 11 will move upwardly in the groove 4 raising the anchoring member 9 forcing the same into the tie or other object thus reliably holding the spike against removal during the vibration of railway rolling stock over the same. When it is desired to move the spike from the tie or other object it is only necessary to insert a clamp bar under the head 2 raising the same upwardly which will move the locking bar setting member 11 downwardly forcing the 'anchoring member 9 into engagement with the bottom wall of the opening 1d and thus the device can be easily removed from the tie or object.

What is claimed is:

l. A spike including a shank, having a liead'at one-end and an inclinedicutting=edge at its opposite end, the front face of said shank provided with a longitudinally extending groove terminating into a recess, said shank provided near its lower end with an opening connnunicating with the recess and groove, an anchoring member :pivotally mounted in the opening a setting bar slidably arranged in the groove and recess, said setting bar provided with an opening, said anchoring member extending through the opening, said setting bar adapted to be moved upwardly upon driving the shank home for raising the anchoring member to a horizontal position for Wedging the spike and holding the same against removal from the object into which it is driven.

2. A spike including a shank, the front face of said shank provided with a longitudinally extending groove, a setting member having a body :portion slidably arranged in said groove and provided with an opening and an outwardly extending head, an anchoring member pivoted in the shank of the spike and having a portion loosely eX- tending through said opening so as to be engaged by a. wall thereof whereby the anchoring :member is turned into anchoring position .as 'thespike is driven into place.

In testimony whereof we affix our signatures in presence 01 two witnesses.
