RAILROAD-SPIKE.

Specification of Letters Patent.

Patented May 9. 1911.

Application led August 20, 1910. Serial No. 578,160.

To all whom "it may concern:

Be it known that I, Ronnurcx BEGG, a citizen ot' the United States, residing at New York, in the county of New York and State cf New York, have invented certain new and useful Improvements in'Railroad Spikes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the samef This inventionrelates to fastenings such as nails or spikes and especially to the kind that are commonly known and used as railway spikes.

At the present time in railway practice,

i rails are fastened to the ties by means of the ordinary spike, and due to the spikes being pointed atA ithe lower extremity they are readily detached from the ties by any upward strain on the rails, being thereby pulled out. of the ties and loosened, which often causes accidental deralments.

The object of my invention is to prevent such loosening of the spikes and rails, and it Yprovides a railway spike of the general form and outline as the ordinary spike and provided with simple,` improved means for rendering the same locked within the tie so as to prevent said spike from loosening and causing the consequences as described' above.

My invention consists ot' the form and features hereinafter fully described and claimed.

In the accompanying drawings Figure 1, shows the spike when driven into the tie.V Fig. 2, is a view of the auxiliary spike and Fig. 3, is a longitudinal section taken centrally through Fig. l; Fig. 4C, is a view similar to Fig. 1, but shwing the auxiliary spike driven iu position and before separating the ends; Fig. 5, is a longitudinal section taken centrally through Fig. 4; Fig. G, shows the auxiliary spike driven to its limit and spreading the ends of the spike, and Fig. 7, is a transverse section through a-b, in Fig. 5. I

Similar reference characters refer to similar parts in the different views of the drawing.

Iu this device, the ordinary railway spike 1, is provided with a channel 2, disposed oppositely to the head 3. The transverse section of channel 2 is adapted to fit the auxiliary spike 4, Fig. 2, which is preferably rectangular in cross section and of a required length. The spike. 1 is ordinarily tapered at. its lower end and a central slit 5 is provided which extends upward to about the line 6 where the said tapering commences.

The rectangular channel 2' slants downwardly and extends from 7a near the upper edge 7 down to 8, which is somewhat below the line 6 at. the upper end of slit-5. The auxiliary-spike 4 is of a harder steel than the spike 1 and is providedwith a head 10 similar to head 3 though of proportional dimensions. The point 9 is diamondshaped, the side.15 ,being straight and the other sides of the pint being beveledo` as shown in the drawing.

In using this device, the spike 1 is driven into the tie as shown in Fig. 1, in the usual manner, as is ordinarily done in practice when fastening rails to the ties. The operator then places the auxiliary spike 4 with its point 9 at 12 and drives the spike downward to its limit until stopped by the head 10. In its downward course the auxiliary spike passes down easily through the channel 2 and merely has to resist the wood at 12a. When the point 9 has reached the lower end 8 of the channel, as in Figs. 4 and 5, the further hammering .on the head 10 causes the point to break through the slit 5 and to force the lower end of spike 1 to spread, so that when the auxiliary spike 4 is driven downto itslimit the lower end of spike 1 is separated and forms the winged parts 13 and 14C as shown in Fig. 6.

Ascan be readily seen the winged parts 13 and 14 form a,resisting means to any. upward force tending to pull the spike 1 out of the tie. The Abottoni of channel 2 is slanted at an angle to the longitudinal axis of the spike in a manner that will give the body of the spike the necessary strengthA and at the same time bring the oint 9 to the proper position, as in Fig. 5, Jlor spreading the lower end of the bolt.

It will be evidentl from the aboven that the aforesaid object of providing al railway spike that will prevent loosenin or the same and thereby preventing deraihnents 1s roo thoroughly aeeoniplished, and that the same is a simple, inexpensive and conveniently operated device,

Having thus described iny invention, I Claim:u

L A railway spike and an auxiliary spike, said. railway spike having a channel cut in its side and a slit. extending from the end of said channel to the extremity of the spike, said slit arranged to allow said auxiliary spike to spread said slitted parts when driven down through said channel.

2. il. railway spike having a channel cut in its side and a slit extending from the end of said channel to the lower edge of the spike, said slit being transversly toY the cutting edge of said spike 3. lin combination with a railway spike, an auxiliary spike naving a diamondeei,eea

shaped point in line with the side of said auxiliary spike. l

il. The combination of'a railway spike and an auxiliary spike, said railway spike having a channel cut in its side and slanted to the longitudinal axis of the railway spike,'said channel being adapted to lit the auxiliary spike and a slit extending from the end of said channel to the lower edge of the railway spike, said auxiliary spike spreadingthe slitted parts when driven down through said channel t0 its limit.

ln testimony whereof I aliix my signature in presence of two Witnesses.

RODERlCK BEGG.
