Beit lmown that I, Jon DANeUIovIoH, a sub3ect of the Emperor of Austria-Hun? gary; residingfat Ely, in the county of St.

vvirs Aknov'vn, ,therporton ot the spike which en-A gages the under surface of the head of the rail; is-.intesralwth the spike proper, and when itis-desired to-bring. this upper part of the Spike into engagement with the rail, it iS 'neeeeeary 1tobend the same after the spike S has ,been driven into place. .This bending .ofthe head engaging partby hammeringeauses the. shankfo the spiketo be loosened, thereby. rendering tho clamping of the frailinsecure. It is to obvate this de'- .fao

feet and to provideanefficient holding means orrailroad rails that the presentim' ventio'n has 'been devised. f'j, '1`he object of my invention, therefore, is improve the construction of railroad '.fspikes of the general type-Bibv .referred to,

whereby their durability, strength and 'utility .are increased and to provide a simple vand' in'expensive ldevice particularly adapted for employment' on curves and capable of el'ectuall-y preventing rails from spreading. The invention consists in the construction and novel combination and arrangement of partsfheieinafter described, illustrated in the accompanying drawings'and more ai'- ticularly pointed out'in the appended claims. In the drawings.Figure 1 is a; vertical section of a-rail and tie showing my in vention 'used in l'connection therewith. Fig. 2- is` a top plan view showing the head of the railv removed. for the pu ose of clearness.

tool.

from movin part is placed on the pin 11 wi A My improved device comprises a main portion 1? and a movable locking portion 10. The main 'portion 1 consists of a base plate 3 having on its underside, near'its inner edge, a rabbet 4 for en aging the upper surface-of vthe rail base. ntegral with the underside of the base plat-e3 and preferably disposed in the center thereof, isa trangular shaped-shank 5 and on the outer edge of saidbase'plate are downwardly depending short Shanks .6. These Shanks form additional securing means for the spike and which will `prevent the latter from/loosening.

.A vertically extending pin 7 having a horizontally disposed opening 8 is provided yupon the upper surface of the base'plate 3 and horizontal lugs 9 are placed on lthe sides of said base plate to facilitate the withdrawal of the spike by a claw or other The movable locking portion 10 consists of a block having a vertically vdisposed I '80 vaperture 11 which engages the pin 7 when the two parts of the spike are united. A out away portion or rabbet 12 is provided in said block and the upper surface of vthe ,block is substantially horizontal, as shown at 13, to fit under Jthe head ofthe rail. A curved surface 14 extends upwardly from the bottom of the block to the horizontally disposed suracel, on 'the sideopposite to the rabbet 12 to engage the web of the rail.

The block is preferably provided with an opening .15, which communicates with the horizontal opening 11, for the assage of a. bolt 16. When the locking member is turned on the pin 7 to locking position the bolt '16 is passed through the opening 15, and the opening 8 in the pin 7, to secure said block on said base. A Cotter pin 17 is passed through said bolt -to retain the same in place.

Patented aug. 18, 1914.

An ear 18, havin an opening 19 for the insertion of a suita le tool, is providedon the side of said block by means" of which the block may be turned. on its pivot. f

Inthe operation of my device, the Shanks of the part 18L are first driven into the tie and the rabbet 4 brought into contact with' the upper surface of the base of the rail, the

contact with the rail being maintained by the short Shanks 6, which prevent the 4spike laterally and the consequent spreading o the rails. .When the shank .of the 'part l" has been driven into tpllace, the

its rabbet'lQ toward the rail head. -A tool is then inserted in the aperture 19 and the part 10 turned on its pivot to bring the surface 13 into Contact with the underside of the head of the rail and the upper portion of its curved surface la into engagementv with the rail web. The pin 16 is then inserted through the openings 15 and 8 which securely locks the two parts of the spike in operative position.

The device has the following meritorious features: The spike Which is simple and comparatively inexpensive in construction, is adapted particularly for use on curves and switches, Where the rails are subjected to amaximum longitudinal and lateral presi sure, and it will etfectually prevent the rails from spreading and getting 'out of, alinement.

It will be appreciated b those skilled in the art, that the device s ovvn is merely typical and may be modiied or kvaried in many ways Without departing from the spirit or sacrificing any of the advantages of this invention as set forth in the claims annexed.

lVhat I claim and desire to secure by Letters Patent is 1. A spike comprising a base having nzeans for securing the same to a railway tie, and a locking member pivotally mounted on the top of said base, and adapted to member pivotally mounted on the top of said base, and adapted to engage the under surface of the head of the-rail.

.4. A spike comprising base having a shank for engaging the tie, a pin provided upon the upper surface of said basei and a locking block mounted upon. said pin, said block having a high side and a lovv side, the locking block being adapted to be piace'd on said pin with its low side to iard the. ".aw and then turned to bringthe high side in engagement With the head and web of L' f if rail.

5. A spike comprising bas-e hav shank for engaging the tie, a locking b i pivotally mounted on said base, and' roec tions provided on the side of said, base. whereby the Withdrawal of said spike may be facilitated.-

6..A spike comprising a base having shank for engaging the tie, a pin provided upon said base, a locking block loosely mounted on said pin, and means for locking said block'upon said pin.

7. A spike comprising a base having a shank for engaging the tie, a pin provided upon said base and a locking block loosely mounted on said pin and having a cut away portlon on one side thereof, a curved surface on the opposite side and a horizontal surface connecting said curved surface and said cut away portion, said block being adapted to be placed on said pin with its cutaway side toward the rail and then turned to bring 'the horizontal surface into Contact with thermderside vof the head 'of the rail andthe up per portion of the curved surface-into en gagement with the rail Web.

In testimonyl whereof I aiiiX my signature, 'in the presence of two Witnesses.
