SPECIFICATION forming part of Letters Patent No. 605,930, dated June 21, 1898. Application led September 2l, 1897- Seral N0. 5521425. (No model.)

.To all whom t may concern: .l

Be it known that I, JOHN H. STAUFFER, re-

A siding at Gap, in the county of Lancaster and State of Pennsylvania, have invented 'a new and useful Vire-Picket-Twisting Machine, of which the following is a specification.

My invention is in the. nature of a device for twisting wire to form it into pickets for wire-picket fences.

The object of my invention is to furnish a simple, durable, and effective machine whereby any one without previous practice orknowledge will be enabled to accurately and rapidly form twisted wire pickets with a loop in one end and the other end forked ready to be applied to a fence.

With this obj ect in view my invention consists in a device or machine for twisting wire pickets, comprising a base having a rigid head at one end and an'iadjus'table head at the other end, the adjustable head being provided with a hook over which to bend the Wire and the fixed head being provided with a journaled shaft carrying a clamp to grasp the two ends of the wire, and a crank or handle whereby the shaft may be turned and the wire 4twisted and formed into a picket, as before described.

My invention further consists in the improved construction, arrangement, a'nd combination of parts hereinafter fully described, and afterward specifically pointed out in the claims.

In order to enable others skilled inthe art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, having reference to the accompanying drawings, forming part of this specification, in whichl Figure 1 is a perspective view illustrating my invention in position for practical use, showing the wire engaged therein prior to twisting and a twisted wire picket alongside.

Fig. 2 is atop plan view of the device as shown in Fig. 1. Fig. 3 is a central vertical longitudinal section through the same. Fig. 4 is a detail perspective view illustrating the various parts of my device detached from each other.

Like letters of reference mark the same parts wherever they occur in the various figuresl of v the drawings.

1 Referring'to the drawings by letters, A is the base 'ofthe machine or device, upon one end of which is@ mounted the fixed head B,

while the other end is slotted at C and is provided with a head D, attached by means of bolts E, passing downward through the head and through the slot C and secured on the lower side of the base bymeans of suitable nuts. These bolts are, before passing through the bolt itself, passed through a hook F, so that when the head D is adjusted and secured in position the hook F is rigidly secured to the head. The head B has a longitudinal groove G on its upper side, about semicircular in cross-section, in which a shaft II is laid and which is secured therein bya clamp-plate I, which Vforms the upper half of a bearing in which the shaft II may rotate.

The shaft H is provided on its outer end with a crank or handle J, by means of which it may be turned, and on its inner end with a plate K, having a central opening L therein. M is another plate of the same dimensions as the plate K and which is provided with a vertical screw-threaded stem N, adapted to pass through the central opening L in the plate K and receive a thumb-nut O for the purpose of securing the two plates together.

To operate my invention, 'a piece of wire P is passed over the hook F and bent at its middle point therein, its two ends being brought back and clamped between the plates K and M.y The shaft Il is then drawn outward until the wire is properly stretched, when it is secured against slipping back by clamping a ring Q around it at the outer end of its bearing. p twisted to any degree of tightness desired, the result being a wire picket, as shown at R in Fig.' 1, provided with a loop S at one end and forked at Tat the other end.

From the foregoing description it will be obvious that I have provided a simple, cheap, and durable device for the purpose intended, which is made of but a fewinexpensive parts and so constructed as tobe but little liable to wear or breakage with ordinary usage.

Vhile I have illustrated and described the best means now known to me for carrying out The shaft is now turned and the wireV IOO iny invention, I do not Wish to be understood as restricting myself to the exact details of construction shown and described, but hold that any slight changes or variations, such as niight suggest themselves to the ordinary inechanic, will properly fall Within the limit and scope of niy invention.

Having thus described 1ny invention, Wha I claim as new, and desire to secure by Letters Patent of the United States, is

l. In a Wire-pieket-twistin g device, the conibination of a base provided with a fixed head at one end and alongitudinal slot at the other, an adjustable head and a hook thereon mounted over said slot, bolts passing through the hook, the head and the slot and secured on the under side of the base by nuts, a longitudinal shaft journaled in the fixed head7 a clamp secured upon the inner end of the shaft, and means for turningthe shaft, substantially as described.

2. In aWire-pieket-twistingdeviee,the coinbination of a base provided with a fixed head at one end and a head and hook adjustable longitudinally of the base at the other end, a longitudinal shaft seated in a seniieircular groove in the fixed head, a elampingplate provided with a seniieircular groove secured to the fixed head and forming the upper half of the shaft-bearing, a plate secured upon the inner end of the shaft and provided with a central opening, a second plate parallel With the shaft-plate having a screw-threaded stein to pass through the opening in the shaft-plate, a thumb-nut engaging the screw-threaded stern to draw the two plates together, a cla1nping-ring to prevent the shaft from bein g drawn inward, and a handle for turning the shaft, substantially as described.

3. In a Wire-picket-twistin g device,the conibination of a base provided with a fixed head at one end and a longitudinal slot at the other7 an adjustable head and a hook thereon 1nounted over said slot, bolts passing through the hook, the head, and the slot and secured on the under side of the base by nuts, a longitudinal shaft seated in a sernicircular groove in the fixed head, a clamping-plate provided with a semicircular groove secured to the,`

fixed head and forming the upper half of the shaft-bearing, a plate secured upon the inner end of the shaft and provided With a central opening, a second plate parallel with the shaftplate having a screw-threaded stem to pass through the opening in the shaftplate, a thumb-nut engaging the screw-threaded stein to draw the two plates together, a clamping ring to prevent the shaft from being drawn inward, and a handle for turning the shaft, substantially as described.
