GATE.

SPECIFICATION forming part of Letters Patent No. 558,060, dated April 14, 1896.

Application filed February 3,1896. Serial No. 577,854. (No model.)

To all whom it may concern:

Be it known that I, JACOB AsHAL FREEsE, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Gates, of which the following is a specication, reference being had therein to the accompanying drawings.

My invention relates to an improvement in that class of gates in which the gate is mounted by means of suitable rollers upon a tilting track, whereby it opens and closes by gravity according to the direction in which the track is inclined; and my invention consists, primarily, in providing means for actuating the opening and closing of said gate from each side of the gateway, either from the inside or outside approach thereto.

A further object of my invention is to provide means to hold the gate in any desired position.

In the accompanying drawings, Figure 1 is a front elevation showing the gate normally closed, while Fig. 2 shows a top plan view of Fig. l, taken at line X X.

Like letters of reference indicate like parts in both iigures.

A, B, and C refer to vertical double posts that are rigidly set in the ground.

D indicates a tilting bar that comprises two arms of equal length d d', which meet at an angle, so that when one arm is in a horizontal plane the other may be slightly inclined. This bar D is suspended at a suitable height to allow the passage of teams and the like and is pivoted or fulcrumed at its angle to one member of the upright double post B at f, so as to swing freely in a vertical plane. he ends of said bar extend between and slightly beyond the double posts A and O and are guided thereby to prevent lateral displacement.

G indicates the gate, which may be of any ordinary or approved form and construction, and it is suspended from the tilting track by hangers h 7L, which consist each of a single suspension-rod and carry rollers r r, which latter are mounted upon the track to allow the nfate to slide laterally thereon.

D The arm d of the tilting bar is directly con trolled in its vertical movement by means of a rack-lever L, that is connected therewith at its end, said rack being geared and working with a pinion P, mounted on a shaft s, which is properly supported on a standard. The rack is held in proper engagement with its pinion by means of a roller-guide g. The shaft s can be driven by a hand-wheel or crank-bar c for effecting the shift or travel of the gate, and said shaft may be extended. or lengthened, so as to bring it to a point within convenient reach of a person on the ground or in a conveyance.

fr r' represent antifriction-rollers journaled in the double post B. These rollers move in a horizontal plane and serve to prevent horizontal displacement by bearing upon the iiat sides of the horizontal bars of the gate if the gate is moved out of line vertically by the wind or other cause.

If desired, the rack may be constructed so as to operate in connection with a worm-gear without departing from my invention.

The operation of the gate is very simple and effective and is as follows: We will suppose that the gate is closed, as shown in Fig. 1. Vhen the crank O is turned, the rack is driven upward until the tilting-bar arms are rocked so as to bring the arm d to an inclined position and the arm d' to a horizontal position, thus causing the gate to roll from the incline thus established to a horizontal plane.

I claim In a gate-actuating mechanism, the combination with an angular bar D hinged or pivoted at its angle to a central post and the gate suspended from said bar by hangers that carry rollers, of a rack-bar connected to and depending from the end of said tilting bar, a pinion properly mounted for engagement, with said rack a guide-roller for holding said rack and pinion in operative relation; and means for rotating said pinion, substantially as described.

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

JACOB ASHAL FREESE.
