JAMES T. NULTY, E PHILADELPHIA, ASsIeNoH y0E ONE-HALE To THOMAS J. cHnMEIE, 0E CHESTER, PENNSYLVANIA.,
SPIKE.
.J SPECIFICATION forming part of Letters Patent No. 352,883. dated November 16, 1886.
Application led May 15, 1886. Serial No. 202,243. (No model.)
To all whom it may concern:
Be it known that I, JAMES T. NULTY, acitzen of the United States, residing in -the city and county of Philadelphia, State of Pennsyl- Vania, have invented a new and useful .1m-A
provement in Spikes, which improvement is fully set forth in the following specification and accompanying drawings, in which the figure represents a side elevation of a spike enibodying my invention.
My invention consists of a railway-spike formed ofa rolled bar sharpened at one end and slightly bent near its middle to enable it when driven to catch over the edge of the iiange or base of the rail, and extending then upward to such distance as when bent sidewise will form a brace or support to the head of the rail.
Referring to the drawings, A represents a spike, which is constructed of a rolled bar of suitabe metal bent in the direction of its length, or deiiected laterally between its en ds, producing a curved shoulder, B, and forming head and point port-ions A A2, which are parallel or approximately parallel and rightlined, and
' continuons of each oth'er,united by said shoulder B.
The spike, as shown at'the left hand of the rail, is driven into the sleeper or other support of the rail adjacentqto the base thereof, and the upper or head point then bent inwardly until its extreme top is beneath'the head of the rail, the shoulder B engaging withf the upper face of the base of the rail, the posi dof 3 5 tion of parts being shown at the right ha the rail. By these means the railv is rmly connected with the sleeper or support, the head of the rail sustained, and as the spike is in contact with the head of the rail it is preven ted from workingloose or vertical displace- 4o ment, the use of sleepers, chairs, 85e., being also obviated.
When the spike is to be removed, its head part is bent outwardly, in order to clear the head of the rail, and the spike may then be extracted in any suitable manner. f
A tool with a claw at itsside, and a pivoted Iclevis for bending the spike in either direction and extracting the sanne, are vshown in dotted lines; but the same form no part of the present 5o v invention.
l am aware that it is not new to form a spikey with ashouldered portion adapted to receive the blows for driving the same; and such l do not claim. p y
Having thus described my invention, what I claim as new, and` desire to secure by Letters Patent, isv h Arailway-spike formed o f arolled bar sharpened at one end and slightly bent near its middle to enable it when driven to catch over the edge of the base of the rail', and extending4 thence upward to such distance as that when bent sidewise will forni a brace or supportto the head of therail, substantially as described and lshown.
