l3e 1t known that I, JOHN Mr Soo'r'r, a citizen oi: the United States, residing-at have invented certain newfland useful Improvements Rail spi-kes, of which the tolloivmg 1s a spec1ficat1on,"referi-nee being had. to the accempanyingdraw- 1.11197. 'iornung a part thereof. i
This invention relates more particularly to spikes for securing railway rails to the wood ties on which they are laid. ,Itsmain objectsfarei to obtain a better hold of the spikes on the fibers of the -w'ood,'tfo prevent the spikes from working loose in dishes and being Withdrawn-therefrom byj'the jars, vibrations, shocks and strains to which the rails are subjected, and gencrallyto-improvethe construction and increase the efficiency of spikes of this class ithout' increasing The invent on consists features of construct on as hereinafterpar- ,ticularl-y described and pointed out ,infthe claims.

Fig.4 is acrosssection on the line 44,Fig. The spikeis formed with ahead a of the hsual onany-surtable shape to engagewith the base flange of a rail. It has. a chisel pointer sharp edge 1) formed at the end opposite the head by the interscction'of upwardly and outwardly diverging concave faces a. The body of the spike is formed in its back and opposite sides with upwardly and outwardly inclined concave notches (Z recessed into the body of the spike and with .transverse crescent shapcd shoulders e also recessed into the body of thee ike extending entirely across the spike in pl anes approxi- The remainingtwo sides f of the body of the spike have plain parallel faces terminating on each side in sharp or acute angled and approximately straight edges which are formed by the intersection of said plain faces with the curved ifaccs of the notches d.

1. A spike provided with a point and adjacent thereto with aniupwardly and outwardly diver ing concave face recessed in the vbody oftie spike and adapted to compress wood fiberslaterally, said spike being rovidecl with a notch also recessed in the ody of the spike whereby a shoulder is formed beyond said concave face against which the fibers which have been compressed laterally by said concave face are adapted to rest.
.2. -A'rail spike of general quadrangular crosssectio'n, two opposite faces of said spike each belng provided with a series of downwardly and inwardly inclined concave' notches and transverse crescentshaped shoulders withinwardly curved edges extending entirely across the spike at the lower ends of the notches,.the lowermost notches of each "series intersecting to form the point of the spike.

3. A rail spike of general quadrangular cross section, two opposite faces of said spike each being prov-ided with a series of downwardly'and inwardly inclined cone/me" notches and transverse crescent-shapedj shoul- ';105'
ders with inwardly curved edges extending entirely across the spike-at the lower ends of the notches and said inptches extending entirely across the spike throughout their length, whereby the sides {if the notches atifijo the corntrgsbf the spike maintain"substantially uniform straight lines, theilowerrnost notches of each series intersecting to form a chisel point for the spike. 4. A rail spike of general quadrangular cross section, two opposite faces of said 5 spike each being provided with a series of downwardly, and inwardly inclined concave notches and transversecrescent-shaped shoulders with inwardly curved edges extending entirely across the spike at the lower ends of the notches-and. said notches extending entirely across the spike'throughout their length, whereby the sides of the notches at the corners of the s ike maintain substantially uniform straig t lines, the lowermost "notches of each series intersecting to form a chisel point for the spike, the other two sides of the spike having plain faces which merge with the concave faces of the notches to form crglntinuous and approximately straight sharp e ges.
5.. A spike provided with a point and adjacent thereto with an upwardly and outwardly diverging concave face recessed in the body of the spike and adapted to compress wood fibers laterally, said spike bein also provided with a second upwardly an outwardly diverging concave face recessed in the body of the spike and adapted 'to compress wood fibers laterally, said second concave face being recessed adjacent said first mentioned concave face, to form a shoulder above said first mentioned concave face, and
said spike being further provided with a notch recessed in the body of the spike above said second mentioned concave face. 1|, form f nature in presence of two witnesses.
