FARM-GATE Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed January 2,1907. Serial No. 850,486.

To all whom it may concern: I

Be it known that I, ALBERT M. STORK, a-cit'izen of the United States, residing at Millers, in the county of Esmeralda and State of Nevada, have invented certain new and useful Improvements in Farm-Gates, of which the following is a specification.

My invention relates to gates and its chief objects are to provide a simple and efficicnt devicefor operating gates from a vehicle as it approaches the structure from either direction, thus permitting it to pass through without requiring the driver to dismount in order to ope'ntlie gate.

Another object of my invention is to providea mechanism that will automaticallylock the gate in any one of three positions, either closed or swung to its open location in either direction.

Further objects of my improvement are toso design the structure that it may be used with equal facility for arninside or division gate, or for an outside closure such as the main gate from the street to the house yard. For

- this purpose I furnish a boom or truss extending towards the street side for the-purpose of supporting the operat- ,ing mechanism and so placed as not to interfere with the travel on the public thoroughfare which would result if a fixed'po'st were .used.

.Iaccomplish the above and other minor results by the use of the novel combination and arrangement of the fixed and movable parts hereinafter clearly described and illustrated in the accompanying drawing which forms a. part of this specifi(:ation,-and pointed out more in detail in the appended-claims.

In the drawing-Figure 1 is a perspective view of a compitne gate and attachments adapted to be used between the street and house yard; Fig. 2 isa partial View of a modified form of the locking device; and Fig. 3 is a fragmentary top plan view of a modified form of the operating arms. I

Referring to the drawing, 1 indicates a hinge-post which supports a gate 5, constructed in the ordinary manner with horizontal bars 6 spaced apart and secured at the ends by vertical members 7. The rear members 7 extend somewhat above the hinge post 4 and are hung thereto on hinges 7 in any of the usual in cthods which 7 will permit the gate to swing through an arc of 180 de grees in order to open widely in both directions. 130- tween the upper two bars 6 a lock or latch 8 is placedand has pivotal] y attached thereto links 9 which are suspended from the upper bar and support the said latch in a horizontal position. This latch has a longitudinal movement on the. links H and may be reciprocatod by hand or by means of a lcvcr 10 having a rcarwardly projecting arm ll. 'lhc h-vcr is bil'lm-atcd' to engage the upper bar of the gate and thirv'ur cud of said latch 8, and iulcrumcd on the bar at [2 and pivotmi to the latch at 153. The front end of the latch is received between the front members 7 and its forward end projects sufficiently to engage the notch of a catch 14 secured to the inner face of the gate post 15. The front members 7 extend above the upper bar 6 and the intervalbetween them is occupied by the front end of a bra ce 16' which is inclined upward and backward. to a point in the rear of the hinge post where it is provided with di verging arms 17. The rear members7 are extended upward to meet said brace 16 and form the rear support therefor. To the free ends of the diverging arms are attached pulley b1ocks18through which pass ropes 19, 19, one 1 end of eachrope being secured to one of the arms 17.- Upon one side of the gate, preferably on the side of the private inclosure, about on a line with the hinge-post and at a suitable distance therefrom is set a post 20,

which carries an arm 21 projecting horizontally over the drive-way parallel with the gate when in closed position. On the under side of the extremity of this arm is a pulley 22 over which the rope 19 is carried and the pendent end is furnished with a ring 23 to provide a secure hand hold when operating the gate. Upon the post 20 at a suitable height to engage the end of the latch 8 when the gate is widely swung in that direction is fixed a retaining catch 24, which will automatically operate the latch when the end of the latt r strikes its inclined surface and hold the gate open 1.

this position until released in the manner hereinafter described. Upon the opposite side of the gate which may be considered the public side, a fixed post would be objectionable for several reasons chiefly that it would interfere with passing vehicles. In order to furnish a support for the operating rope upon that side, therefore, I provide a truss or girder formed of boards or rails 25, 25, securely fastened to the rear face of the hinge post 4 and projecting upward atan angle. The truss is strengthened by braces 26 and extends at right angles to the gate line to a suitable distance where it is provided with an arm 21 similar to the one attached to the post 20 and in like manner is furnished with a pulley 22 over which the rope 19 passes and terminates in a. hand ring 23. Between the attachments of the ropes 19, 19, to the arms 17 and. the pulleys 18 the said ropes pass through a free ring 27, and through the same ring is carried a rope 28' one end of'which descends along the underside of the brace 16 until it reaches a pulley 29 which changes its direction its end being secured to the extremity of the latch operating lever arm 11. From the hinge post 4 an arm 30 projects horizontallyvand at its outer extremity carries a latch 31 pivoted thereto at 32 a stop 33 limiting its downward movement and serving to hold it at a suitable height so thatwhen the gate is swung outwardly, or on that side from which the arm 30 projects, the upper edge of the upper bar 6 of the gate will be automatically engaged by a notch 34, and held until released by traction 'made upon the rope 28 one end of which is secured to the extremity of said latch 31.

It may sometimes be desirable to furnish means for locking or latching the gate open when swung in either direction as would be thecase if truss arms were used on both sides of the gate as there would be no post to which to fasten the catch 24. To provide lor'such. a co'ntingency'l secure a cross bar'to the rear face of the hinge post 4 as seen in Fig.2, so that it projects on either side. 'A semicircle 36 preferably formed of a metal strip is pivoted to the ends of this bar at 37 and is provided with duplicate notches 38 on either side one of which will automatically engage the upper edge of the top-bar 6 when the gate is swung open. With this device the main latch may be.removed and both ends of the rope 28 attached to the semicircle, the gate being held in its initial 'or. clo'sed position by a median notch 36*. Siilce said semicircular locking strip will hold the gate in each of its several positionsit may'be properly termed a universal latch. I

The principle of my invention may be conveniently applied. to an ordinary gate with a post of the usual height by the modification shown in Fig.3. Duplicatc arms 39 are secured at one end to the sides of the upper bar 6 of the gate and extend backward in divergent directions and are joined by a brace 40 which holds the structure rigid. The arms 39 are sufficiently jel'vated to clear the post 4 when the gate is swung.

The method of using the appliance is as follows: When traction is made upon one of the ropes by grasping the ring23 the loop of the rope which passes through the ring or eye 27 will be straightened and the said 35' eye carried with it sufficiently to exert a pull upon the rope 28 which will lift the arm 11 and retract the main latch 8, at the sametime raising the retaining latch 31. By continuing to pull upon the main rope "the gate will be swung wide open and upon releasing the ring 23 the latch 8 or the retaining latch 31 depending upon which way the gate is swung will hold -traction is made and the middle notch 36 will engage the gate automatically and retain it in closed position.

It is evident that changes maybe made in the construction and design of the details of my invention as herein disclosed without departing from the spirit and scope thcreoiand I do not wish, therefore, to be limited to the exact devices set forth.

- Having thus described my invention. what I claim is:-- v

1. An automatic gate, including an inclined hriu-c extending rearwardly in the vertical plane of the gate, a plurality of diverging arms secured to the free extremity of said brace, a plurality of operating ropes attached to said arms and engaging an eye, a main latch and a re taining latch, a. rope attached to said main and retaining latches and engaging said eye, and means for supporting said operating ropes.

2. An automatic gate, including a rcarwardly extend .ing operating urm, secured to the gate, a laterally ex tending truss, an automatic hitch attached to the hinge post, and means for operating the arm secured to the gate and the said latch.

53. An automatic gate, including :1 rcurwardly extending arm secured to the gate, a laterally extending iixcd arm, a universal latch pivoted to n iixcd support, operating means for the arm secured to the gate and for the universal latch.

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