Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed July 18, 1915. Serial No. 40,689.

To all whom it may concern Be it known that I, JOSEPH J. Gmsn, a citizen of the United States, residing at Ambia, in the county of Benton and State of Indiana, have invented certain new and useful Improvements in Spikes, of which the following is a specification.

This invention relates to railroad spikes of that type provided with means to lock them in the tie when embedded therein.

As a principal object, it is comprehended by this invention to provide a spike with locking means, such that when the spike is driven home into the railroad tie or bed, it may be then looked in position against withdrawal.

It is a more specific object of the invention to form a railroad-spike with a longitudinal bore therein from which a lateral opening extends at an angle through one side of the spike, and to loosely insert with in this bore a locking element having a pointed angular end, the latter adapted to be driven through the opening into the tie by the insertion in the bore of a wedging key after the spike has been embedded, and removable from the tie in the same manner.

A still further object is to combine with a spike formed in the manner set forth, means for employing an auxiliary head upon the spike, for the initial driving thereof, in order that the head of the spike may not be so battered as to prevent proper 1nsertion of the locking means in the bore of said spike.

The above and additional objects which will be hereinafter more specifically treated, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

With reference to the drawings, wherein there is illustrated the preferred embodiment of this invention, as it is reduced'to practice, and throughout the several views of which like characters of reference designate similar parts: Figure 1 is a longitudinal sectional view taken through a spike, showing the locking means as driven into place; Fig. 2 is a similar view illustrating the method of removing the locking means; Fig. 3 is also a view of the same type showing the manner of employing an auxiliary head, and Figs. 4 and 5 are plan views of the spikes of Figs. 1 and 2 respectively, the wedging key being shown in section in each of the views.

The spike, which is to be constructed after the manner of the present invention, may follow in outline any well-known or approved construction. The spike is designated as a whole by the numeral 10 and at its lower end tapers to a point 11 permitting its entrance into the tie when driven home. At the opposite extremity the spike is formed with an enlarged head 12 and extending inwardly from this head and longitudinally of the spike body, is an elongated recess or channel 13, the innermost extremity of which connects with an opening 1 1 at a right angle to the bore and forming a continuation thereof, said opening leading outwardly through one side of the spike. the bore 13 is placed an insertible locking member comprising a shank 15 and a locking point 16 projecting laterally from the lower end of the shank, said point being of such length as to be accommodated within the bore 13 when the locking member is inserted therein and also adapted to be driven through the aperture 14 and into engagement with the tie mate *ial. A, wedging member or key 17 is employed to direct movement of the locking member in the manner to be immediately explained.

The spike is first driven home at the desired place, an auxiliary head being employed to prevent a battering and malformation of the edges of the channel 13. This head includes a portion 18 adapted to receive the blows of the hammer when driving the spike into the tie and provided with an integral stem 19 which is received within the bore 13 and serves to maintain the auxiliary head upon the spike head 12. After the spike has been driven home, this auxiliary head is removed and the locking member 15 is inserted in the bore, occupying at this time. an initial position as shown in Fig. 2. The wedge member 17 is then inserted between a wall of the bore 13 and the shank 15 of the locking member in such manner as to drive the latter laterally as shown in Fig. l, forcing the point 16 outwardly through the opening 1 1, engaging, of course, with the wood of the tie and naturally preventing Withdrawal of the spike. If it be desired to remove the spike, the key 17 is withdrawn and driven between the locking member and the opposite wall of the bore,

as shown in Fig. 2, to disengage the locking pin from the wood of the tie, after which the spike may be withdrawn from the tie in the usual manner.

While in the foregoing, however, there has thus been illustrated in the drawings and described in the specification such combination and arrangement of elements as constitute the preferred embodiment of this invention, it is desired to emphasize the fact that such minor changes in the matters of proportion and degree may be made in later adaptations of this device as shall not alter the spirit of the invention as defined in the appended claims.

\Vhat is claimed is: a

1. The combination with a spike formed with a longitudinal bore closed substantially throughout its length and opened at the top and having a lateral opening at the bottom leading from the bore to the outside of the spike, and a locking member having a laterally projecting pin on its lower end freely removable and insertible into said bore, said pin adapted to be forced laterally through said opening into the tie after the spike has been driven thereinto.

2. The combination with a spike formed with a longitudinal bore, of a laterally angularly extending opening leading from said bore to the outside of the spike, a locking member having a laterally projecting pin on its lower end freely removable and insertible into said bore, a wedge means adapted to act against one of two sides of said bore and said member to force the pins through or withdraw the same from said opening.

3. In a spike formed with a longitudinal bore and a communicating lateral opening extending from the lower end of said bore to the outside of said spike, a locking member including a shank having an integral laterally projecting locking point on its lower end freely insertible into said bore and adapted to be forced through said opening and into the material holding said spike without distortion of said locking member.

4. In a spike formed with a longitudinal bore and provided with an opening extending from its lower end at an angle to said bore through one of the walls thereof to the exterior of the spike a locking member comprising a shank and an integral laterally projecting locking point freely insertible 7 Copies of this patent may be obtained for five cents each, by ddressing the Commissioner 01' Patents, Washington, D.
