GATE.

SPECIFICATION forming part of Letters Patent No. 260,643, dated July 4, 1882,

Application tiled April 10, 1882. (No model.)

To all whom it may concer/n Be it known that I, JACOB E. BLACKBURN, of Fredericktown, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Gates; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, which form a part of this specification, andin which- Figure 1 is a side elevation of my improved gate. Fig. 2 is'a perspective detail view of the hinge-post with its appurtenances, on an enlarged scale. Fig. 3 is a similar view ofthe latch-post with its adjustable latchbearing and holding-plate. Fig. eis aperspectiveviewy of the latch-bearing detached. Fig. 5 is a sectional view of the front end of the gate with its spring-latch and latch-cap. c Fig. Gis aperspective view of the rear end of gate. Fig. 7

is a detail view of the upper bearing for'the pivoteil hinge-bar. Fig. 8 is a perspective detailview of the adjustable shouldered hingeloop F detached from the gate; and Fig. 9 is a horizontal sectional view through the said loop, hinge-bar, and gate-bar on the line indicated by the letters a' x in Fig. 1.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to swinging gates; and it consists in the construction and ar rangement of parts of the hinge, substantially as. hereinafter more fully described, for the purpose of working, elevating, fastening, and preventing sagging of the gate to which my improvement is applied.

In the accompanying two sheets of drawings, A represents the hinge-post, and B the latchpost.

C is a bearing which is cast upon or made in one piece with a screw, c, which is screwed into post A near its top.

D is a ilattened bar, of east-iron or wroughtiron, about two feet and two inches (more or less) long between its top and bottom shoulders, d d, by which pintles are formed, the upper one of which is inserted into the top bearing, C, while the bottom one is stepped into a bracket or rest, E, which is fastened upon the l post by suitable wood-screws@ rlhe flattened bar D has a series ot' shifts or notches, a a, extending between its shoulders, which are adapted to receive a casting composed of a ,flattened loop, F, having a screw threaded shank,f, and shoulders e e. The loop Frides upon bar D, and isot' such a width'that it will t into any one of the notches a.,

Upon the end piece, G, of the gate is screwed a small casting, g, which is made with a rectangular slot or opening adapted, to flt the shouldered end ot' the loop F, which may be tightened up against it by means of a nut, H, having a handle, h, which said nut works upon the outer end ot' the threaded shankf, that is inserted through abore niadein the end post, G.

Byloosening the nut H'shankfmay be withdrawn some distance through its bore',rthereby releasing loop F from that of the notches a with which for the time being it is engaged, and enabling it to be slid up or down upon bar D, according to whether it is desired to raise or lower the gate. The proper elevation ot' the latter having been determined, the loop F is again interlocked by tightening up the nut H h with its appropriate notch in bar D.

restsJ i, by which it is screwed Aupon post A. This bar is of round iron, and isclasped by au open loop, J, the shank of which is inserted through the end post of the gate and nutted thereto, so as to hold it rigidly in position. By making this loop open it is prevented from binding upon bar I, on which it rides, as its ends may be spread a little, lit' desired, and thus vcause it to be moved easily up or down upon the bar.

Instead of fastening the several parts C, E, and I upon or in the post, they may be attached to a board or plank of suitable length, width, and thickness, as shown at A', which is in turn fastened to the post by the screws of the several parts, which should project a sufficient distance on the other side of the board for that purpose.

The latch-post B has a longitudinal mortise or recess, which is faced with a ilanged plate, b, having a series of 'I1-shaped slots, b b. The latch-bearin g, which is preferably made of castin one piece-Wiz., the rounded part or bear- I is an iron bar, cast with top and bottom iron, consists essentially of three parts, cast ing proper, (marked K,) which has a transverse groove or notch, I, in its middle, aplate, L, which extends from the middle of said partin a downward direction, and another plate, M, extending back of part K at right angles to plate L, and made with shoulders m m, one on each side.

The latch-bearing, constructed as above described, may be inserted into any one Aot" the T-shaped slots b', and held in place therein by passing the shank or narrow part of plate M in front of the shoulders m m down into the stem or vertical slot of its appropriate opening b', the shoulders preventing the withdrawal ot' the bearing from the slot, while the bottom plate or extension, L, impingng upon the face of the flanged plate b and confined between its ianges, prevents tilting ot' the device and holds it in its proper position for engaging with the latch.

The latter is operated by a handle, N, and spring O, aud is confined at its upper end within a cupshaped cap, P, which serves the triple purpose of forming a rest for the front end of the gate, (upon the rounded part K ot' the latch-bearing,) of conining the play oi' the spring-latch, and of protecting the latter, iu a measure, from snow or dirt.

The gate is prevented from sagging by a pair of iron rods, Q, which extend obliquely from the head of the gate to the middle of its bottom, to which their lower ends are fastened by a bolt passing through them both, and also through the bottom rail or rails and vertical middle brace of the gate. The flattened upper ends ofthe brace-rods are bent or doubled around the end post, G, underneath the casting g, and held in place by staples lc. At the opposite end ot' the gate are the brace-boards R, which are secured on the gate by bolts or nails and at their lower ends stepped into the lower end of the vertical middle brace.

This gate, it will be seen, can be adjusted between its posts so as to keep it clear of' snow or other obstructions in the road. It can be elevated to such a height that fowls and small stock may pass under it, and, whatever its position, it cannot be thrown from its hinges by stockpassingnnderit. Aftereachadjustment ot'the hinge-loop F the latch-bearing K L M is ot' course adjusted at a corresponding elevation in one ot' its slots b', so as to hold the gate in its proper horizontal position between posts A and B.

The rest or bracket E, into which the lower end of bar D is pivoted, may be cast with or upon a screw in like manner as the top bearing, C, and thus screwed into the face-plank A and post A, instead of fastening it thereto by separate screws.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- In a gate, the adjustable hinge-loop F, having screw-threaded shankfand shoulders ce, nut H, having handle h for turning it, and the gate having perforatedend post, G, and hollow casting g, adapted to receive and fit the shouldered end of loop F, constructed and combined substantially as and for the purpose herein shown and set forth.

In testimony that I cla-im the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JACOB E. BLACKBURN.
