IMPROVEMENT IN ,FARM-GATES.

Specification forming part of Letters Patent No. 146,678, dated January 20, 1874 application filed August 27, 1873.

rounded lower edgeof the top bar of the gate.

Letters of like name and kind refer to like parts in each ligure.

My invention' has for its object the construe! tion and adaptation of a fence-gate in such a manner as will admit of its easy and convenient use by the passer, whether he approaches on foot, upon horseback, or in a carriage; and to this end it consists in so making and adj ustin g the gate that it will slide horizontally upon rollers; and in making the upper or bearing bar of the gate with an incline from, its longitudinal center toward either end, and in rounding the under side of the bar, so that the movements of` the rgate on this side as a bearing shall be smooth and sure upon the channeled rollers; and in notching the upper bar, `so that when the gate is shut it shall fall into these notches and lessen, in a great measure, the concussion of the gate upon the post in closing it; and in the arrangement of the rollers in and over which the top rail moves in the several posts on different horizontal lines, so as to enable the double-beveled rail to move automatically, in part, when the gate is being opened or closed; A and in the general detail of the construction and arrangement of the several parts, whereby the device is made to operate easily and successfully.

The gate is shown by A in the drawing. It is made in general in any ordinary or suitable `manner. The rails a and A, or body portion of the gate, are sustained at the ends by the standards A, and the gate otherwise strengthened by cross bars or braces in the usual way. The top bar A extends a little distance beyond the forward end of the gate, while at the cline.

channeled roller C, pivoted in the top of the post B. The posts B, B', and B are set in the ground in the usual manner. The part of this bar which constitutes the upper rail of the gate has upon its under surface a double in- This commences at a point, a, about the longitudinal center of the gate, and the inclines therein extend to the ends of the gate. The under edge a of this bar is rounded for its entire length. As the bar constitutes the horizontal bearing of the gate, and nds its support or rests upon the channeled rollers C, pivoted in the top part of the posts orstandards B, B', and B.- This rounded edge lts close upon said rollers, and enables the gate to be easily and surely moved back and forth. In the under edge of the top bar, at such points as shall correspond to the distance between the rollers in the posts B and B at either end ofthe gate, are notches D. The oiiice of these notches is to form seats,`into which the gate falls when it is closed.. These seats serve as stops to arrest the motion of the closing gate, and prevent nearly all concussion upon the side or end posts, and are of very material advantage in thus saving strain on these posts;

at the same time the rests are so easy that they do not in the least offer resistance to the force put forth to open the gate.

By this construction, also, the gate can never warp, or drag, or sag down,A but will have always, and at all points, a sure support.

Upon a post, E, fixed in the ground at any suitable distance from the gate, is another channeled'roller or pulley, C. Upon and over this passes the rope F, one end of `which is fastened to the top rail or bar A of the gate, at the point of its greatest vertical depth, from whence it extends to and passes between the two channeled rollers c', which are pivoted vertically in the clip o, placed upon the top or upper part of the end post B; or i these rollers may be adjusted and` iixed in any other convenient manner for the same pinpose. pulled with a quick short motion by the person approaching, force enough is communicated to the gate to cause it to move upon the When the free end of the rope is now rounded under edge ot' the top bar over the roller C in the post B, while the under edge of the extended arm bears against the upper' roller C in the post B until the central point of this portion of the bar passes the roller in B', when the momentum causes the gate to move upon rollers C G in posts B B home to the outer post B, and leave the way between the gateposts B and B wide open. rlhis can be done when it is desired to drive a carriage through the gate; but when the gate is to be opened t'or a pedestrian, an easy pull upon the string will bring the gate just half open, and it will then rest upon its arm on the roller in post B, and upon the top bar on roller in post B and eau be shut by hand by the person after he has passed through. rEhe post E on the opposite side is located, constructed, and equipped in like manner, and the operation of the gate ou that side is similar to that just described.

It will be seen that I have arranged the roller in the central post B somewhat below the level of the horizontal line from the rollers in posts B and B, and this arrangement ena bles me to accomplish eiteetually the motion and the results I have just now deseribed. I have also provided eyes, or an y suitable means, at G, in the tops ofthe vertical posts or standn ards in the ends of the gate. 'lo these I may attach the ends of a single oord, by means oi which I can open the gate by one continuous pull. The looped end oi this rope, hanging down from the roller or pulley in the top ot the post E or id', can be pulled until the gate is set wide open, and by a like movement the gate can be olosed.

I intend by this speeieation to cover both these means for operating the gate, as one is almost identical with the other.

In constructing or setting up my device, I do notv always use three posts. In some instances, I find it very convenient to use, instead ot' post B, suitable standards affixed to the fenee, and so adjusted and put together as to answer every end and purpose I have new set out for the post B. In some instances, it may be found ot' advantage to lool( the gate by means ot' a pin thrust through a hole above the roller C in post B. 'This will bind down the projeeting forward end of the top bar, so that the noteh D will engage upon the roller, and thus the gate will be lightly and securely closed.

By my invention, I have provided a device that will open upon its bea-ring without swing ing to either side., and can be pulled upon or shut in a direet line without any sidewise or angular motion, and that will operate with the least possible friction. It requires so little force that a woman or ehild even ean manipulate it with ease, while, when Closed, it cannot be opened by beast or cattle.

` Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- Y Y l. The gate A, having the top bar or ,bearing rail A double-inclined on its under side, as described, and combined with the posts B, B', and B, having the rollers (l C C and C, arranged as set forth.

2. The gate A, with its exten ded top rail A double-inclined on its under side, and adapted to be moved upon and over the rollers C C C, and provided with the looking notches or in d entations D, snbstantiall y` as and for the pui14 pose set forth.

The post E and pulley C", cord F, and pivoted rollers c, combined with the gate A, constructed as described, and operating in the posts B, B and B, and upon therollers C C G, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of August, 1873.
