SPIKE-EXTRACTORs SPECIPICATIONfonning part of Letters Patent No. 803,888, dated August 19, 1884.
(No model.)
2'0 (all wit/mi it 122/14; concern:
Be it known that I, EDGAR Tgsniinr, a citizen of the United States, residing at Boston, in the county of Suffolk and State of lilassachusetts, have invented certain new and useful Imp rovemeutsin Spike-Extractors; and I hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.
The obj ect of this invention is to provide an implement of improved construction for extracting bolts and spikes from timber, especially for withdrawing rail-spikes i'roin railroad-ties without injury to the spikes, and with great saving in time and labor.
The peculiarities of my implement will be readily understood from the drawings, which show its points of difference from the ordinary bar heretofore used for the same pur pose, but liable to bend or break the spikes.
Figures 1 and 2 represent my improvedin'iplenient in two different positionsone showing its first application. to the driven spike, and the other the position when partly drawn out. Figs. 3 and 4 show in enlarged perspeetive and front views the lower port-ionof the tool; and Fig. shows how the spike-head is held by the points of the jaws until it is completely extracted, its body meanwhile entering the groove between them.
The entire implementis preferably of steel. It consists, essentially, of a body or handle, A, preferably about four and a half or five feet long, smooth, and somewhat tapering, as
shown, and a curved head, B, having two projecting jaws, G O, riveted to it, the extreme points or outer edges of which are turned toward each other, as at o c, leaving between them a groove or opening, D, of suflieient breadth to admit the body of the spike without allowing the head to pass. The points or inward-turned edges 0 001" the jaws extend far enough beyond the head 13 to give room for the head of the spike not only when the tool. first seizes it with the points 0 c beneath the sides of its head, but also when the spike-head has tilted upon such points in drawing out the spike. The points remain beneath the head of the spike until it is entirely drawn out, as in Fig. 5, the curved back of the implement sliding somewhat on the tie to permit a steady upward movement, and the fulcrum continually changing meanwhile. The body of the spike enters the groove 1), between the points 0 c, and is thus kept from being bent or broken while drawn upward. The jaws O C are formed distinct from the body B, and are firmly riveted to it. This construct-ion perniits the use of a better grade of steel in the jaws, upon which the principal strain comes, than in the head and handle, and also renders repairs more convenient and economical than in prior devices where the head and jaws are integral.
I claim as my invention- The improved spike-extractor herein de scribed, consisting of the handle A and curved body'B, in combination with the jaws O C, riveted firmly to the sides of the body B, and provided with the inwardturned edges 0 c to engage with the spike-head while admitting its bodyinto the groove D between them, sub stantially as set forth.
In testimony whereoflhereto alfix mysignature in presence of two witnesses.
EDGAR T. SHARP.
