FARM -GATE.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed January 17, 1920. Serial No. 352,044. 7

To all whom it may concern.

Be it known that I, ALBERT OLTMAN, a citizen of the United States, a resident of Eureka, in the county of Voodford and State of Illinois, have invented new'and useful Improvements in Farm-Gates, of which the following is a specification.

This invention has reference to new and useful improvements in farm gates.

The principal object of my invention is the provision of suitable tracks or rails upon which the gate, by means of rollers mounted thereon, travels from open to closed position or vice-versa.

A further object of my invention is the provision of obstructions at each end of the tracks or rails for the purpose of looking the gate in either open or closed position.

A further object is the provision of suitable means for actuating the gate when it is desired to open or close the same.

That the invention may be more fully understood, reference is had to the accompanying drawing forming a part of this application, in which Figure 1 is a perspective view showing a gate embodying my invention;

Fig. 2 is an enlarged typical section through one of the tracks or rails, showing the -character and arrangement of the obstruction for locking the gate in the open or closed position.

Fig. 3 is a side elevation of Fig. 2, and

F ig. 4 is an enlarged detail of the sheaves through which the rope or cable for opening the gate operates.

Like characters of reference denote corresponding parts throughout the figures.

1 denotes a typical farm gate provided with the long and short upstanding end portions or posts 2. 3 designates a pair of rollers suitably carried on the long and short upstanding portions or posts 2, respectively, of the gate, by means of the brackets 41. Suitably secured to the fence posts 5, 6 and 7 are the tracks 8 on which the gate travels, by means of the rollers 3. 9 designates the obstructions which look the gate withinthe open or closed position.

These obstructions preferably take the form of bolts secured through the tracks or rails 8, the rounded upper ends of said bolts forming effective locking means to hold the gate open or closed. 10 denotes a rope or hicle has cable suitably 12 and 13 denote cables or ropes, suitably secured to the cable or rope.

10, and passing over thesheavesrld and ex tending in. opposite directions therefrom and over the sheaves .15 and depending therefrom to enable the occupant of a vehicle to pull same when desirous of opening or closing the gate. The transversely extended arms 16 which are suitably secured and braced to the fence post 6, are for the purpose of supporting the sheaves 1 1 and 15 and are presumed to be of such length that when the oncoming vehicle is drawn by a team, there will be ample room for the team between the depending ends of the rope or cables 12 and 13 and the gate, and it will not be necessary for the driver to dismount from the vehicle to open the same. This is also true after the vepassed through and the occupant is desirous of closing the gate.

The sheaves 14 are swingably mounted in the clevises 17 by means of the rings 18 connected to the brackets 19 suitably secured to the transversely extended arm 16, the purpose of which will be described later.

The post 20 with the lateral connections 21 to the post 5, constitute an end stop and a seat for the gate to enter when closed, to protect same against any tranverse strain when in closed position. The post 22 is provided for approximately the same purpose at the opposite end of the gate.

In operation, see Fig. 1, the occupant of a vehicle pulls the depending end of the rope or cable 12 or 13 to open the gate. In view of the fact that the bolts 9 act as an ob.- struction to the opening of the gate, it will be understood that the pull must be of sufficient force and duration to pass the roller 3 over the bolts 9, and impart enough mo mentum to the gate that it will continue to roll on the tracks toward the opened position, after the point 11 of the upper rail of the gate has passed under the sheaves 14 and the depending ends of the ropes or cables 12 or 13 have been released. Through the momentum thus acquired, the gate will travel to the opened position, locking itself in that position by means of the bolts 9 at the opposite ends of the tracks 8.

It will, of course, be understood that when the gate is in the opened position that the "tracks planes, a gate having and posts, which dif- "fer in height, a roller on each post, one

point 11 on the upper rail of the gate 1 has reached the same position relative to the sheaves 14, but'on the opposite side thereof to that shown in Fig. 1. It will thus be seen that when this same operation isperformed when the gate is in the opened position,:that the gate will close and effectually lock itself. What I claimis:

1; In a sliding gate,

disposed in in combination, two difierent horizontal for each track, obstructions on each track near their opposite ends for locking the gate opened or closed, said obstructions comprising bolts secured through the tracks and having abutment heads, and a pair of cables connected to said gate for opening the gate and hold the same in open or closed position, and cables connected to the gate to open and close the same. a

In witness whereof, I have hereunto aflixed my hand and seal this 13th day of January, 1920.
