GATE.

SPECIFICATION forming part of Letters Patent No. 327,606, dated October 6, 1885.

Application filed January 5, 1834. Serial No. 116,515. (No model.)

To aZZ whom it may concern.-

Be it known that I, FLAVIUS W. SHELLA- BARGER, a citizen of the United States of America, residing in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to self-closing gates, commonly called drive-gates;and it consists in a certain construction of the devices for operating the same, which will be hereinafter described.

The object of my invention is to make the gate easy of operation, certain and positive in its movements, and not liable to get out of order; also to have means for adjusting the operative parts connected with the wheelirons, so as to retain ease of operation under variable conditions of weather.

Figurel is an isometric view of a selfclosing gate having my improvements. Figs. 2 to 11 are enlarged details of the same.

The gateis hung upon hook or pintle hinges A and B. The upper hinge, A,consists of an open frame of frustum shape projecting from the post, through which an eyebolt, a, extends, with which the hook-section a engages, and the lower hinge, B, consists of a broad right-angled plate with a long vertical slot having an angle extending toward the post H,at the middle part,the hook or pintle h, which is seen attached to the gate-stile, and is inserted through said slot being thrown from the middle of the slot to either end as the gate is thrown open in the opposite direction.

A pair of dogs are hinged to a plate on the inner side of post H, at the proper height, their inner ends converging to form a notch in which rests the pin 9, projecting from the free end of the gate. There is suflicient space between the free end of the gate and post H to allow the lower part to move endwise toward post- H, without touching the latter when operated, it being pushed toward said post as the pintle is drawn to either end of the slot in the lower hinge-plate, thus lifting the free end of the gate and releasing pin 9 from the notch formed by the hinged dogs on post H, which dogs form the stops to hold the gate when shut. In operating the gate,

as the wheel-iron is thrown down the pull-rod j pulls the pintle h to the end of the slot on that side, thus elevating the free end of the gate, and at the same time freeing pin 9 from the notch in which it rests, and as the rear of the gate is inclined it readily swings from post H in the direction opposite to the side from which it is operated.

The tendency to pull the wheel-iron on the opposite side down is prevented by the counterweight, (on that side,) which is adjusted on its arm so as to throw the wheel-iron to its normal position and retain it there. There is just sufficient slack in each of the chains attached to the pull-rods and connecting them with the plates 0 and D to allow tl1enito-.be r

brought to a level with the rods (in operating the gate) without strain upon either, the dropping of the front end of the gate after release of pin 9 being almost simultaneous with the tension of the rods and chains, which are instantly relieved as the gate swings open, and the wheel-irons resume their normal position by the operation of the counter-weight 1).

An additional post, I on the same side of the roadway as the hingepost H, is connected with the latter by a board, I, against which the gate swings when open. The intermediate angle-irons connecting the wheel irons with the rods j are pivoted on the end of board I, which extends beyond the post H for that purpose. Thepull-rodsj which open the gate are connected directly with the lower end of the hook or pintle h below where it engages with the tripper 7c and pull it back from the center to the end of slot it toward. the wheel-iron being operated on, and the gate is swung-back in the opposite direction. In Fig. 7 the movement of the hook or pintle h and the lower end of stile f, to which it is attachcd,are shown in dotted lines. The operation of opening the gate is therefore performed by shifting the lower pintle from one side to the other of the 9 5 hinge-plate B within the slot n in the horizontal projecting part m of the hinge-plate. The pintle h rests in the angle at of the slot 12 when the gate is closed, and at this point it is held in engagement with the head k of the tripper we is, which latter is pivoted between two perpendicular flanges, in, under the part at at the center of the plate.

The tripper consists of an angular bar, one

. counterpoise to hold the pivoted arm in contact with the pintle when the latter is at the center or angle a of slot n. The office of the tripper is therefore to retain the pintle at the angle of the slot when the gate is closed and prevent-its being shifted, except by the operation of the pull rods. The pintle being, formed at its engaging end with perpendicular flanges i,which straddle head lcof the tripper, it cannot be released from the latter until operated by the pull-rods from either side.

By reference to Figs. 5 and 8 (which show a section through line as, Fig. 5) it will be seen that the pintle h has projecting flanges i, which straddle the square end is of the tripper. The flanges project at an angle of about forty-five degrees outward and backward, and they serve to retain the pintle in the center 'of the slot, and in engagement with the head of the tripper when the gate is closed; butin the operation ofswinging the latter open the flange ion the side toward which the gate swings catches an angle of'the tripper head' 7c, pivoting upon it until the gate is thrown part way open, when the pintle is disengaged and thrown back into the end of the slot opposite to the direction in which the gate swings. By this means the lower pintle is thrown to one side of a perpendicular line, and the front or free end of the gate drops as it swings back from across the roadway.

The devices for operating the pull-rods consist, first, of the wheel-irons s, the angular bar D, having hillbSi and t, which have their ends connected by chains 1" and r and a link, 1', to the end of arm 0 of the right-angled plate 0. (Seen pivoted upon the bar or board I in Figs. 1 and 9.) The plate Chas, in addition to the two arms 0 and 0, a long. arm, 0, extending from the latter, with a weight. p, made adjustable thereon by a set-screw. The upper end of arm 0 is connected by three or four links of chain to the pull-rod j, the latter connecting with the gate-pintle h, as before described. By reference to Fig. 9 it will be noticed that a small arm, 0, extends from the left side of o and engages the link W- and holds the chain out from lever 0 when the wheel-iron sis thrown toward the right. The arm 0 has a notch in its end to engage the link, and thus prevent the chain from coming in contact with the edge of the plate. There is just sufficient slack in each of the chains to allow the end arm, 0, when acted upon by the wheel-iron to open the gate, to move (in a horizontal direction) just twice as far as the distance which the pintle must move from the 6:

center to one end of the slot n, and so much slack in the chain that this movement of arm 0 will be just sufficient to pull the pintle to the nearer end of said slot.

By the adjustment of weight 1) the vertithe latter by the pull-rods j, the gate is slightly 7o tilted, and its weight carri s it around in swinging open; v

The post-plate section of the upper hinge, A, has the holes a in its ends made oblong in the direction of its length to make it adjustable upon its fastening-bolts b. This plate has bars 0 and d, through which the eyebolt a extends, and is secured between the latter and the post by a nut.

I claim as my invention 1. The combination, with the wheel-iron, of the angle-plate D, having arms t and t on the outer end of the journal of said wheel-iron, the chains 1" and 1*, extending upward from said arms, respectively, the pivoted right-an- 8 gled plate C, having a lateral arm or lever extending therefrom provided with a weight,and means for adjusting the latter for the purpose of keeping the wheel-iron perpendicular, as set forth.

2. In a self elosing gate, the combination, with the lower hinge devices, the pull-rod, and the wheel-iron having the two-armed plate attached thereto, and chains connected therewith, as described, of the intermediate rightangled plate pivoted. between the wheel-iron and the pull-rod and connected with the lat ter, and having a lever and weight for adj osting the wheel-iron and keeping the same perpendicular, as and for the purpose set forth.

3. The combination,with the slotted plate m, having ears m, and the tripper is, pivoted between the latter, of the gate-pintle h, having the flanges t, adapted to engage the head k of the tripper upon eitherside to retain the pintle in the center of the slot, at the angle of the same, when the gate is closed, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
