CONSTRUCTION 0F YOSTS FOR FIELB-FENGES.

Specification of Letters Patent No. 22,712, dated January 25, 1859.

To atl whom it may concern.'

Be it known that l, Jol-IN Daowx, of Huron, in the county of rayne and State of New York, have invented a new and useful Improvement in Portable Fences; and do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, Figure l being a side elevation of a portion of a fence constructed in my improved manner; Fig. 2, a top view thereof; Fig. 3, a transverse vertical section thereof inthe plane indicated by the line fr fr, Figs. l and Q.

Like letters designate corresponding parts in all the figures.

The sect-ions of the fence are formed of simple rails A, A, connected together by upright pickets a, a, or in any convenient manner. The ends of each of the rails A, A, of adjacent sections, are halved together, as represented at b, h, so that they will present the uniform width of single rails. The ends of the lower rails, where joined together, rest in chairs B, B, of suitable length and size to serve as a rm foundation for the fence. The notch or mortise c, (Fig. 3,) in the chair, which receives the ends of the lower rails, is made somewhat longer than the width of the oined rails, and may have a dovetail form, as shown in Fig. 8; and the joined rails of the lower rails, which rest therein, are made, in that case, of a corresponding form. A wedge (I, of suitable shape. driven into the notch, beside the lower rails, holds them securely in place. Small notches are made in the outer edges of the upper rails at their joints, substantially as represented at f, f, Fig. 3. These notches are made of sutlicient width to admit the edges of the braces C, C, therein, and said braces may have corresponding notches g, g, in their inner edges, to receive the rails. The braces project a little distance above the rails, where they are connected together by means of a clamp 71, put over the ends of the braces, and fitting into small notches or holes z', lz', in the braces; or any other equivalent means of firmly holding the braces together may be employed. One of the braces is secured firmly to the chair (as seen at 7c, 7a, Fig. 3,) so as to incline inward toward the fence. The other brace is then pressed inward and downward with some force, thereby lirmly tightening the rails, and making the fence irin and steady. 1When it is brought to a proper position, its lower end is secured to the chair by a single nail, screw, or hook, Z, (Fig. The fence may be further tightened at any time, if it becomes unsteady, by removing tbe nail or screw Z, and pressing the brace in more closely toward the center of the chair. It thus constantly acts as a powerful lever to hold the fence firmly and closely, while its fellow brace particularly sustains the fence in its proper position.

The fence is readily taken down at any time by separating the lever braces from the chairs. and removing the keys which conline the rails in the chairs, when the parts scparate from one another. I

That claim as my invention and desire to secure by Letters Patent, is*

The arrangement of the braces C, C, one fixed and the other hinged or pivoted thereto, in combination with the rails A., A, and chair B, substantially as herein specified.

The above specification of my improved fence signed by me this 11th day of October, 1858.
