specification of Letrers Patent.

Application filed October 527, 191%. ileriel 797,563.

llc it known that We, .lbsur-ri i hurrnm', and WILLIAM RYAN, ()llLlI TOUS of the l. ruled States, and residents of .lnlihanopohs, county or Marion, and Stateof Indian-a, have 111- vented a certain new and useful Spike; and we do hereby declare that the following is a iull clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to improve the construction of a split spike, nail, orad and the like in order that the legs thereof will spread and twist in various ways and thereby coins into binding engagement with a much larger portion of the timber into which it is driven than is the case with the ordinary split spike.

The novel feature of the invention consists in providing the end of each spike leg with .ippositely curved double or beveled surfaces whereby when the spike is driven, the legs will not only spread from each other in two directions, but they will twist also. Along with the foregoing is the provision of at least one of the lcgswith e bevel which will tend to prevent the head of the spiliefrom turning very much. I

The Withdrawal of spikes from cross ties and railways is one of the coimuo'n causes of reilwiiy accidents. The constant jarring; of the track by the train gradually elevates and Withdraws the spikes Without any great resistance of the timber in the cross tiej ll ith spikes oi? the kind herein set forth such result cannot follow. The spikes cannot be Withdrawn and the rails will always be held secure upon the tics. r

The nature of the invention Will be understood from the accompanying drawings and the following description and claims.

in the drawings, Figure 1 is an elevation of said spike. Fig. 2 isa perspective View of the some after it has beendriveu. Fig.3 is an elevation of the spike. viewing it from one side. Fig. 4 is a section through a cross tie and railway oil and showing the spike in place in the cross tie, one leg o'l 'the spike heing shown by dotted lines. Fig. 5 a bottom View of the spike.- Figs. 6 and 7 are sections onthe lines 6-6 and 7--7, respectively, of Fig. Fig. 8 is an enlarged section on the line 8--S of Fig. 4:. Fig. 9 is a. bottom View like Fin". 5 of a modified form In Ficr in the form heretofore described.

"the head oflhe splice from tw 4: there is shown a railway rail 10.

and cross tie ll with a split spike therein. The spike has a round hood because as the spike is being" driven the twisting movement of the legs cause, the spike to turn somewhat and the round head will always engage the flange of the railway rail regardlP of the an'iounl: of twisting ol the spike. ".lhc Spike is split for al at its enlirclcngth so as to provide two parallel legs 13 and l l and. each loo has near its lower end. lateral shoulders 15 which serve as barbs to oppose the Withdrawal of the spikes.

Theend of each le has an outside sirai ht' i iiace illl. The leg 1. has a straight face 21 on one side and the other leg: has an upper straight surface diagonally op u'zsito the surface 21 on the other leg, but below the straight surface 2 the leg); 14: is her lied at 255 and on the same side as the surface the surfaces 525 on the two legs are beveled reversely to each other.

In the modified form in Fig. 9, there is an inner beveled surface 35 and a lateral'beveled surface -56, said two bercled surfaces correspondimg with the beveled surfaces 25 Therefore; While the spike is being driven, if it be of the form shown in Fig. E the two lateral curved beveled surfaces 36 will cause the legs to unread longitru'linally of the timber, as shown in 8, and the two innerbeveled sin-faces Will at the same time cause the legs to spread transversely oi the timber. These two results will also follow from the compound or curved heveled surfaces 25 in the form shown in Fig. 1, with the addi tional result, however, which is caused by the curved surfaces, namely, the legs will he twisted while being driven, as shown in Fig. 0. In the form shown in Fifi. the lungs are not twisted. but appear as shown in Fig. I.

The Function ol the hovel Eli? to prci'cnt lSllllQ' to any great extent. it causes one leg; oi the spike, as shown in Fig. 1-. on entering; the Wood to curveor spread longitudinally 0F the timber less than the other leg. and tends to reduce the turning movement of" the head or body of the spike.

".lhe invention is:

.l. A split spike with the legs thereof recon, the shouldered ends of the legs being I legs having an additional bevel for reducing beveled both longitudinally and transversely substantially as set forth to-a single point at the extreme end of each leg, the points of the two legs being substantially diagonally opposite each other sot-hat the legs will both spread and twist while being driven.

A split spike with the ends thereof provided with inner surfaces beveled both longitudinally and transversely so as to cause the legs to spread from each other and inultaneouslytwist, the end of one of said the spreading movement of one of said legs to reduce the twisting nioveinent of the head 15 of the. spike while the spike is being driven.

In witness whereof, "We have hereunto aflixed our signatures in the presence of the witnesses herein named.
