IMPROVEMENT IN METALLIC FENCES.

Specification forming part of Letters Patent No. 210,247. dat d N vember 26, 1878; application filed June 3, 1878.

[To all whom it may concern:

Fig. 2. Fig. 4. isa side view of a filling-block used in a fence which is not level. Fig. 5 is an end view of the block shown in Fig. 4. Fig. 6 is a view of a modified form of a block for the lower rail.

I will first describe an end post. The letter (t denotes a base-block; b, a disk fixed thereon by screw 0. From this disk rise bars 01, bearing an upper disk, c. From the base-block, and from one of the upright bars d, project ears f for the rails to take hold of. The rails g are double both above and below, one on each side of each ear, to which they are attached by screws h, which allows the fence to start off level or on an upward or a downward incline.

I have shown the first two sections of the fence, beginning at the left hand, as on a level. I will now describe one of the posts at the meetingof the two level sections: The letter idenotes a cap, which sits down upon'both rails. The letter j denotes a similar but reversed piece, forming a socket for both rails. The screws 70 run from the cap, between the rails, down to the socket j. From the socket j, and fast with it, depends the post-body l, on the lower end of which is the cap at, sitting down on both the lower rails, which lie in the reversed cap or socket n, from which the post-base 0 runs to the ground. Screws p connect the cap m to the socket n.

I will now describe ajoint midway between posts at the meeting of the second and third sections, with the third section running down an incline. The letters 4" denote the two railcaps, and s the two rail-sockets; t, the connecting-screws. These caps and sockets are cast with one half to fit to the level rails and the other half to fit to the inclined rails. If a post were to come at this place the caps and sockets on the post parts would be the same in shape as shown at this joint. Obviously,

the caps and sockets can be cast to fit any diflerence'in the trend of the fence.

The third section runs down an incline, and here the special utility of the ears f and pivotscrews h is made manifest.

The pickets u are straight bars, and are held in place by filling-blocks. The letters w denote the filling-blocks where the fence is level-the same in shape for both the upper.

and the lower rails. The shape of these filling-blocks is illustrated in Figs. 2 and 3. They have the lateral top plate, w, which rests on the top of the rails, the lateral bottom plate, w, which rests under the bottom of the rails, and the connecting-web w, which runs down between the rails. The web is perforated by the orifice w for the passage of screws .00, which connectthe two rails.

The filling-blocks and the pickets are tightened in place by driving home the conical or wedge-shaped pins y.

The pickets can be of any convenient shape in cross-section. I prefer them round.- When round they can be prevented from turning by slabbin g the sides where they touch the fillin gblocks.

The filling-blocks for a fence on an incline are varied a little in shape to adapt them to the situation. I show the adaptation in Figs. 4 and 5. The ends are beveled. This permits the pickets to stand vertical.

Of course a third and intermediate line of rails can be used where a line of shorter pickets is desired.

Fig. 6 shows a form of block for the lower rail, used when it is desired that the pickets shall not project below the lower rail. The

pickets, in this case, rest upon the projection 2.

I claim as my invent1on- 1. In combination, the rails g, the filling blocks to w w, and pickets u, arranged for use as described.

2. In combination, the rails g, filling-blocks w w w", pickets u, screws :0, and wedge-pins base 0, and. screws 19, arranged for use as dey, arranged for use substantially as described. scribed.

3. In combination the rails 9 caps 1' pickets s, and screws t, arranged for use as de- CHRISTOPHER FRINK' scribed. Witnesses 4. In combination the rails 9, cap 2', socket H. D. MARGY,
