SPEGIFIGATION forming part of Letters Patent No. 602,955, dated April 26, 1898.

Application filed March 2 6, l 8 9 6.

To aZZ whom it may concern.-

Be it known that I, VAN R. PAIGE, a citizen of the United States, residing at Hopkinton, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Spikes; and I do 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, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to spikes, and more particularly to that class of such devices which are designed. for and employed in connection with the securing of railroad-rails to the supporting-ties.

The invention has for its object the production of a simply and cheaply constructed spike possessing advantages in point of efficiency and durability in that when in place my improved spike maintains a resistance to the maximum degree against the side thrust of the rail.

Other advantages existing in my improved spike will appear in the following description, which is directed to the details of construction and operation and which is to be read in connection with the accompanying drawings, in which- Figure 1 is a perspective view of my improved spike. Fig. 2 is a vertical central sectional view. Fig. 3 is a side elevation of two spikes, one of which forms the auxiliary for augmenting the resistance.

Referring to the said drawings byletter, A denotes my improved spike, which is headed atits upper end or at b and there provided with side flanges b b, which allow of the ap plication of a claw-bar or similar device for withdrawing the spike. The lip 11 of the head, which in practice engages the foot of the rail, has its under side inclined, as shown, to insure a proper contact on the rail-foot and for another purpose presently to be explained. This lip extends forwardly of the head, and from the rear of the latter extends a bridge 0, which is integral with the spike and of the same lateral dimension. From the Serial No. 584,995. (No model.)

extreme end of this bridge depends a blade d, the outer side of which forms a continua tion of the end of the bridge and the inner side of which is inclined to bring the point of the blade to a comparatively sharp edge. The width of the blade corresponds in dimension with the thickness of the bridge, while the thickness of the blade is considerably less, as shown. The upper surface of the head is eonvex and extends to a point about midway of the bridge, and the top of the latter from this point isinclined or sloped on aline coincident with the inclination of the under side of the lip in order that when two spikes are employed-as, for instance, as shown in Fig. 3 the lip of the second-driven or auxiliary spike may properly bear and have a good contact on the inclined top of the bridge of the firstdriven spike.

In practice I rely for lateral resistance upon the peculiar shape and arrangement of the blade, which, being comparatively thin and driven crosswise of the grain of the tie, will not split the latter, but will, by reason of its breadth, maintain a firm resistance against the side thrust of the rails. The blade is in tegral with the spike, and consequently with the bridge, from which latter it depends or drops, and hence is driven with the spike in a manner to preclude of its being bent or fractured during the operation. The inclination of the top of the bridge, aside from serving as a bearing for a second spike when driven, also has the advantage of strengthening the bridge at that point which receives the greatest strain during the driving opera tion.

From the foregoing it will be evident that I have combined in my improved spike all of the advantages which go to make a device of this character efficient and durable.

My improved spike when driven in place offers the maximum resistance, will not split the tie either while being driven or when driven while under strain, is simple in its construction, readily made, and may be produced at a comparatively low cost. The construction, moreover, permits of two or more spikes being driven in line in cases where extraordinary resistance is to be met with.

lip, whereby the outer sides of the bridge and blade are in conformity with the under side of the lip, substantially as and for the purposes described.

In testimony Whereof I a'lfixmy signature in presence of two witnesses.
