GATE-OPERATING MEANS.

Specification of Letters Patent.

Patented. Mar. 36, 1915.

Application filed May 11, 1914. Serial No. 837,894.

To all whom it may concern:

Be it known that we, LINUs G. PETERSON and GUSTAV ADoLPH PETERSON, citizens of the United States, residing at Colbert, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Gate-Operating Means, of which the following is a specification.

This invention relates to improvements in gate structures especially designed for road ways entering a fenced inclosure and the invention has to do more particularly with an improved operating means for swinging the gate into open or closed positions irrespective of the direction of approach of the team or vehicle.

The operating means of our invention is particularly adapted for a one way opening gate in contra-distinction to that form of gate which opens or swings in two directions or on opposite sides of the latch post.

It is the object of our invention to provide cables, ropes or the like in connection with our improved operating means and an especially novel feature resides in leverage means for increasing the purchase of the opening cables so as to facilitate the operation of opening the gate in one direction.

Other features and objects of the inven' tion will be more fully described in connection with the accompanying drawings and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawingsz-Figure l is a perspective view of a gate equipped with one form of operating means embodying our invention, and showing the gate in a closed position. Fig. 2 is a plan view showing the gate in an open position. Fig. 3 is a view in slde elevation of that portion of the gate adjacent the latch post and illustrating our improved gate latch. Fig.4 is a plan view thereof. Fig. 5 is a view in elevation of a single pulley block. Fig. 6 is a view in elevation of a double pulley block.

Like characters of reference designate similar parts throughout the different figures of the drawings.

In thet form shown, 1 designates a hinge post and 2 designates a latch post.

A retainer post is indicated at 3 and 1s disposed in the road way equidistantly from the hinge post 1, with respect to the spacing therefrom of the latch post 2 so as to hold the gate in an open position. The latch post 2 is provided with a keeper 4 which is designed to arrest movement of the gate toward a closing position beyond the dotted line position shown in Fig. 2, to the left of post 2. The keeper 4 is provided with a latch cam 5 for guiding the latch into socketed relation with the keeper. A similar form of keeper 6, provided with a cam 7, is mounted upon the retainer for road post 3.

A gate is indicated as a whole at 8 and includes a latch stile 9 and a hinge stile 10. The stiles 9 and 10 are connected by upper and lower rails 11 and 12 and the intermediate portion of the gate may be made up of wire mesh or any other suitable skeleton work. The hinge stile 10 is hingedly mounted as indicated at 13, to the hinge post 1 so that the gate may be swung in one direction into an open position as indicated in Fig. 2, in full lines, or into a closed positionas indicated in dotted lines.

The gate is provided with a latch bar 14 which is slidably mounted in a guide way 15 in the latch stile 9 for projection therethrough so as to coact with keeper 4. A latch operating bar 16 is pivoted to the gate at 17 and has a slot 18 into which a pin 19 on the latch bar 14 projects, for operation of the latch bar upon swinging movement of the operating bar 16. The free end of the operating bar 16 extends through a strap guide 20 which serves to limit movement of the operating bar 16 in opposite directions.

A spring 21 is interposed between the strap guide and the operating bar 16 to normally urge the latter into a position to latch the bar 14 with the keeper 4.

On the upper rail 11 we pivotally mount at 22, a cable operated bar 23, to the ends of which a cable 24 is connected, on opposite sides of the pivot 22. The cable 24 extends through an opening 25 in the operating bar 16 and may be knotted or otherwise prevented from moving freely through said opening 25.

A leverage bar 26 is securely anchored, preferably on the rear of the hinge post 1 in a manner to cause said bar 26 to occupy a position at an angle other than at a right angle to the gate, when the same is either closed or opened. Furthermore, said bar 26 is anchored in such a manner as to dispose its ends on opposite sides of the hinge post 1, one end 27 thereof being rearwardly disposed with respect to the hinge axis of the gate and the other end 28 thereof, being disposed forwardly of saidv hinge axis, the purpose and function following from this particular and novel disposition of the bar 26 being hereinafter more fully described. On the rearwardly disposed end 27 we mount a pulley block 28 having a single pulley 29 and on the remaining end 28, we mount a similar block having asingle pulley.

On the gate 8, and preferably on the top rail 11 thereof, we fixedly mount a leverage bar 30 with one end thereof'anchor'ed to the rail 11 in a manner todispose said bar 30 at an angle to the plane of the gate, other than at a right angle thereto. The disposition of the leverage bar 30, is such as to dispose its free end at one side of the gate and rearwardly of the hinge axis of the latter irrespective of whether .or not the gate is in an open or closed position. On the free and rearwardly projecting end of the gate leverage bar, we mount a double pulley block 31 having two pulleys 32 and 33.

An inside pulley post 34 is provided with adouble pulley block 35 having two pulleys 'mounted therein, the construction of Which may be similar to the block shown in Fig. 6. An outside pulley post 36 is provided with a pulley block 37 having two pulleys, and being of like construction with respect to the blockshown in Fig. 6.

It will be understood that the gate may open inwardly or outwardlyand that the designations herein made with respect to the inside and outside pulley posts are merely for convenience of identification as we reserve the right in practice'to dispose the parts in the position in which it is desired to have the gate open. v V

An inside gate closing and latch operating cable or line is indicated at 38 and is trained over the lower pulley of block 35. Qne end of the closing line 38 is provided with a hand grip 39. Said cable or line 38 is trained about the pulley of a block 40 which isfixedto the forward end 28 of the stationary leverage bar 26 and its end is connected at ll with the cable bar or lever 23. \Vhen the gate is in an open position, as shown in full lines in Fig. 2, tension on closing line 38 will first retract the latch bar 14 from the keeper 6 so that the gate will be free to be moved or swung into a closed position. It is usual to cant the hinge post insuch a manner as to cause the gate to normally seek a closed position by gravity when it is once released from an open position, and therefore, the power required for closing the gate is somewhat reduced with respect to the pull required to open the same.

An inside gate opening line or cable is in- 'dicated at a2 and is trained about the upper or remaining pulley of block 35 and terminates in a hand grip 43. Said opening line 42 is trainedoyer pulley 33 in block 31 of the gate leverage bar 30, and'itsiemaini'ng end is secured to cable lever 23 on that side of pivot 22 opposite the end towhichclosing' line 38' is connected.

Now by reference to Fig. 1, it will be seen that'the gatelev'erage bar affords a very 7 material purchase on pull of the opening line %2 by reason ofthe fact that the gate leverage bar not only extends a considerable distance laterally of the gate but also'rearw wardly of the hinge aXis thereof. i'lhus when the opening line 42 is'placed under tension it will first operate the latch bar 14 to release thejlatter from theke'eper 4c, and r chase afforded by leverage bar 30, will greatly reduce the pull necessary to completely open the gate into the full line position shown in Fig. 2. p An outside'gate opening lineor cable is indicated atl lfand is trained about the u per' pulley in' block 37, the terminahen'd of said cable 44: being provided with a hand grip as. Said cable a4 is trained about the pulley of block 46, mounted on therear end 27 of post leverage 26," the remaining end of said openingli'ne or c'ablefll being connected with the cable lever "23 f at 47. Tension on opening line 44 willserve first to actuate lever 23v to release latch bar 14 from keeper 4, and further pull will serve to sw ng the gate intoan open position.

An outside closing line 418 is trained over the lower pulley of block 37 and 'is provided with a hand grip 4'9. 'Saidclosi'ng line 48 'is trained about pulley 32 in block 31 aa may.

be spliced, at 50,'to inside opening line 12, or otherwise connected 'at 47 with cable lever 23.

Fromthe position shown in fulllines in Fig. 2, it will be seen that tension on the outside gate closing line 48 will first release the latch bar 14 from the keeper 6 andwill then shift or eXei-t shifting stress on the free end of the gate leverage bar 30 to shift said free end to the right of Fig. 2 3116. swing the gate toward a closed position.

It is believed that the, utility and advan tages of our invention will be fully understood from the foregoin g de scription, and

while we have herein shown and described gate structure in advance of its hinge axis and extending rearwardly of such axis and laterally of the gate in a direction opposite to the direction of opening movement of the gate, a leverage bar having one end fixed to the gate in advance of the hinge axis thereof and disposed at an acute angle to the plane of the gate with its free end in advance of the gate With respect to the direction of opening movement of the latter and extending toward the hinge axis, the free end of said bar having a pulley engaging an intermediate portion of the line to maintain the same laterally in advance of the gate, and a flexible closing line connected With the gate structure and extending laterally of the gate in a direction corresponding to the opening movement of the latter, the free end of said bar having a pulley engaging an intermediate portion of said closing line, substantially as described.

2. In a gate operating means, a hinge post, a gate structure hinged to said post, a flexible operating line connected With the gate in advance of its hinge axis to open the gate and extending rearwardly of such axis and laterally of the gate in a direction opposite to the direction of opening movement of the gate, a flexible closing line connected With the gate in advance of the hinge axis thereof and extending laterally of the gate in a direction corresponding to opening movement of the same, and leverage means fixed to the gate and engaging said opening and closing lines to maintain intermediate por tions thereof laterally in advance of the gate With respect to the direction of opening movement thereof, substantially as described.

In testimony whereof We affix our signatures in presence of tWo Witnesses.
