of ssouri, have invented certainnew and useful Improvements in Registering Wire- Stretchers; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a registering wire stretcher. V

An object of the invention resides in the provision of 'an improved device of this character by means of which the wires of a fence may be stretched.

.A further object of the invention resides in soconstructing the device that the wires of the .fence'may be'stretched by the same force and so that that force will be indicated to the operator.

A further object 7 in so constructin the device that thewires of the fence ma be stretched conveniently by one operator.

With these and other objects in view, such as will-appear as my description progresses, my invention comprises the combination and arrangement of partsv as set forth in and falling within the scope of the appended claim. Y p

In the drawing: Figure .1 is an elevational view of a device constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view; Fig. 3 is a transverse sectional view showing the take-up mechanism,

and Fig. 4 is a similar view taken on line A4=otFi.2.v I

The emodiment of the invention. illustrated in the drawing includes a tubular 1 casing 1 which is open at one end andis with a pair of guide arms 2 which provided carry a guide eye 3. Extending transversely or the casing 1 withinthe same is a bar A to which one end of a helical spring 5 is attached, which spring extends longltudinally of the casing and is provided on the other end with a pointer '6 which extends through a slot 7 in the casing and cooperates with a series of numbers 8 to indicate the force, in

pounds. whichis applied to the sprin. A

of the invention resides rod 9 is secured to the end of the spring adjacent to the pointer 6 and extends through a guide eye 10 which is mounted in the open end of the casing 1. A chain 11 is secured to this rod 9 and 18 provided with a wire engaging hook 12 for attachment to the wire which is to be stretched.

Extending transversely of the casing within the same and parallel to the bar 4 is a shaft 13 on which a drum 14: is secured.

A flexible attaching member 15 is secured to and windable on this drum and extends through the guide eye?! for attachment to a permanent member such as a tree or a post. A ratchet 16 is secured to this shaft 13 and coiiperates with a" pawl 17 to prevent the movement of the shaft in one direction. The shaft is provided with a crank handle 18 by means of which it may be cranked.

. In operation the member 15 is attached to a tree or post and the member 12 to the wire which is to be stretched. As the handle 18 is turned the member 15 will be wound upon the drum 14 so that the wire will be stretched. As the wire is stretched the pointer 6 will move from one to the other of series of numbers 8 so asto indicatethe force in pounds which is exerted upon the wire tostretch the same. It is obvious that this presence of the pawl and ratchet on the winding drum shaft will permit the operator to release the handle 18 while he reads ,has merely been for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the details of construction without departing from the spirit of the invention or exceeding the scope of the appended claim;

at I claim is:

In a wire stretcher, the combination with a tubular casing, of a winding drum mounted adjacent one end thereof and within the same,'a flexible attaching member secured to and windable on said drum, means for preventing the rotation of the drum in onedirection, a bar extending transversely of the casing, a spring connected to the bar and a I 1,208,605 wire en gaging member associeted the In testimony whereof, I afiix my signaspring, the sand spring having a pointer on ture, in the presence of two witnesses.

one end thereof and the casing having a GREEN B. WILLIAMS. series of numbers thereon whic cooperate Witnesses: 7 5 with the pointer to indicate the force ap- W. F. Tnmm'r,
