SPECIFICATION forming part of Letters Patent No. 416,955, dated DecemberlO, 1889.

' Application filed April 9, 1889. Serial No. 306,544. (No model.)

T0 at whom it may concern;

Be it known that I, DWIGHT H. SCOTT, of Flora, in the county of Charles Mix and Territory of Dakota, have invented a new and useful Tension Device for Wire Fences, of which the following is a full, clear, and exact description. p

My invention relates to a tension device for wire fences, and has for its object to provide a means for expeditiously taking up the slack in wire fences and retaining the said wire under tension; and a further object of the invention is to provide such a device of simple and durable construction.

The inventionconsists in the novel construction and combination of the several parts, as will be hereinafter more fully se Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the device. Fig. 2 is a section on line .90 0c of Fig. 1. Fig. 3 is a plan View of the device, illustrating the wire as wound around the device, but not secured thereto; and Fig. 4 is a similar view sition to be left upon the wire.

The device is constructed substantially in, the form of a spool, comprising a tubular body 10, provided at one end with an annular flange 11 and a diametrical slot 12, extending through the flange and the body adjacent to said flange, as best illustrated in Figs. 2

a series of teeth 13 are produced, which teeth are inclined laterally and inwardly over the body, as illustrated in Figs. 3 and 4:.

The opening in the body 10 at the end carrying the teeth 13 is rectangular, as shown at 14 in Fig. 2, to receive the end of any desired form of wrench, the preferred form of wrench, however, being a crank-arm having one extremity rectangular to enter the equiva lent opening l tof the device. The rectangular part of the opening is made to terminate at or near the center of the body to prevent the inserted wrench or crank-arm from volved until the wire is wound thereon sufficiently to take up the slack. The device rotated in a direction opposite to that in 6c which the teeth are inclined, and when sufficient tension has been exerted upon the wire the said wire is made to engage-with the inner curved surface of one of the teeth, as illustrated in Fig. 4, and as the tendency of the coil upon the body is to turn the said body in the direction of the slant of the teeth the tension of the coil serves to effectually bind the tooth engaged to the strand of wire with which it engages. It is evident that as the teeth 13 may be placed very close together the wire may be drawn only a quarter of an inch, if .so desired.

Having thus described my invention, I claiin as new and desire to secure byLetters Patent- 1. As an improved article of manufacture, a tension device for wire fences, comprising a tubular body having a flange atone end, a diametrical slot extending through the said body at said flanged end, and a series of teeth radiating from the opposite end of the body and inwardly and laterally inclined over the body, substantially as shown and described.

2. As an improved article of manufacture, a tension device for wire fences, comprising a tubular body 10, one'sectionof the bore of which is rectangular, said body being provided at one end with an annular flange and a diainetrical slot extending through the said flange, and with hook-like teeth radiating go from the opposite end, laterally and inwardly inclined over the body, substantially as and for the purpose specified.

DWVIGHT H. SCOTT.
