HERBERT K. TABLER, OF PLYMOUTH, ILLINOIS.

GATE.

Application filed May 28,

To all whom it may concern:

Be it known that I, HERBERT K. TABLER, a citizen of the United States, residing at Plymouth, in the county of Hancock and State of Illinois, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction of swinging gates, more especially the means for operating the same, and to provide simple, inexpensive and efficient combined g'ateactuating and latch-operating mechanism, adapted to positively open and close a gate, and capable of swinging the same either slowly or rapidly by a single continuous pull.

A further object of the invention is to provide gate-actuating mechanism, designed for operating gates opening in one direction only, and to enable such gates to be opened to an angle of ninety degrees so as not to obstruct the road-way.

\Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended: it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is an elevation of a gate provided with operating mechanism, constructed in accordance with this invention, the gate being open. Fig. 2 is a plan view partly in section, the gate being shown closed in full lines and open in dotted lines. Fig. 3 is an enlarged vertical sectional view of a portion of the operating mechanism. Fig. 4'. is an enlarged plan view, illustrating the construction of the side levers and the shiftable device of the intermediate lever. Fig. is a detail perspective view of one of the side levers. Fig. (3 is a detail view of the lower portion of the intermediate lever. Fig. 7 is a detail sectional view of the intermediate lever, the shiftable device and one of the side levers. Fig. 8 is a detail sectional view, illustrating the construction of the latches. Fig. 9 is a detail view, illustrating a modification of the Specification of Letters Patent.

* shiftable device for the intermediate actuating lever.

Like numerals of. reference designate corresponding parts in all the figures of the drawings.

1 designates a swinging gate, designed to be constructed in any preferred manner, and connected by suitable hinges 2 to a hinge post or support The gate is equipped with upper and lower rei ersely arranged latches 4; and 5, adapted to engage suitable stops or keepers of a main latch post 6 and a supplemental latch post 7. As'the gate swings in one direction only, the latch post may be equipped with any suitable number of stops or buffers for limiting the swing of the gate,'and the latter will thereby be effectually prevented from swinging past a latch post and there will be no danger of the gate being forced open by pressure at either side of it.

Each latch consists of a lever frame, preferably in the form of a casting and composed of upper and lower outwardly pr0- 'jecting arms 8, a vertical connecting bar or portion 9 and inwardly extending ears 10. The cars 10 are pivoted between a pair of spaced ears or eyes 11 of the gate, and the outwardly projecting arms support a vertical roller 12, which is adapted to engage a keeper. The latch is also equipped with an inwardly extending arm 13, projecting from the lower ear of the latch and connected with a coiled spring l t, secured to the gate and adapted to hold the latch in position for engaging its keeper. The upper latch is adapted to engage a keeper 15 of the supplemental latch post, and the lower latch is adapted to engage a keeper 16 of the main latch post 6.

The upper and lower latches of the gate are connected by upper and

lower rods

17 and 18 with

vertical rock shafts

19 and 20, located at opposite sides of the gate and mounted in suitable bearings. The connecting rods, which are crossed, connect the rock shafts at one side of the gate with the latch at the opposite side of the gate, and they are provided at their inner or rear ends with loops 21 and 22, connected, respectively, to lower arms 23 and 241 of the

vertical rock shafts

19 and 20. The loops are adapted to permit a limited play of the parts to enable the latches to automatically engage their respective keepers, but instead of employing bracket 33.

the

rods

17 and 18, wires or other suitable flexible connections may be used, and a small amount of slack may be provided to effect this result.

The vertical rock shafts are provided at their upper ends with rearwardly extending

cranks

25 and 26, connected at the top by'a transverse link 27 and carryingantifriction rollers 28. The cranksare adapted to be oscillated horizontally to unlatch the gate, and this operation is accomplished by means of a horizontally disposed oscillatory lever 29, fulcrumed on a vertical pivot .30 between upper. and lower horizontal poi-.- tions of a bearing bracket 31. The bearing bracket .31 is located above the hinge post or support 3, and is secured to an inclined upwardly extending arm 3220f a supporting The lever 29, which extends transversely of the road-way or gate-way, has its front portion located between the cranks of the vertical rock shafts, and when the lever 29 is oscillated, it is adapted to engage one of the cranks for unlatching the gate. lVhen the vertical crank shafts are partially rotated by the lever 29, the lower arms are swung rearwardly and the latches are withdrawn from engagement with the keepers. The coiled springs operate to return the latches to their engaging position as soon as they are free to move. A continued movement of .the lever operates to swing the gate on its hinges.

The supporting bracket is provided with a vertical attaching portion, which is secured to the rear face of the hinge post or support. Extending from the supporting bracket are rearwardly projecting arms 34, between which is pivoted an upwardly extending intermediate or central lever 35, carrying a shiftable device 36, adapted to alternately engage and actuate a pair of side levers ,3? and 38. The side levers 37 and 38 are arranged at the outer faces of the rearwardly extending arms 34 of the supporting bracket, and they are connected with the same by a pivot 39 of the intermediateor central lever 35. The side levers 37 and 38 are connected by suitable rods or

bars

40 and 41 with the horizontal oscillatory latch-operating and gate-actuating lever 29 at opposite sides of the pivot or fulcrum thereof by means of bolts 42, or other suit- .able fastening devices. The horizontal oscillatory lever is provided with lateral extensions or portions to which the front ends of the connecting bars or

rods

40 and 41 are secured, and the said connecting rods, which are located approximately at right angles to the forwardly extending portion of the horizontal lever, are adapted to oscillate the same to open and close. the gate. The connecting rodlor bar .40 lies in advance of the pivot 30 and the lever .37 isadapted to be oscillated to .openthe gate. The other rod or bar 41 is located in-rearof the pivot :30, and its lever 38 is adapted to be oscillated to close the gate. 'The side levers are alternately engaged by the intermediate actuating lever, and when one of the side levers is swung forwardly or inwardly towards the hinge post by the intermediate lever, the other side lever is carried outwardly or rearwardly through its connection with the horizontal oscillatory lever 29.

The shiftable device, which is centrally pivoted to the intermediate lever 35, is approximately V-shaped in cross section, and is provided with inclined or angularly disposed sides 43, and it is held at an intermediate or central position by a spring 44. The lever 35 is provided at its lower portion with spaced sides 46, and is equipped with transverse webs or connecting portions 47, pierced to form ears for the reception of a pintle 48, which pivots the shiftable device to the intermediate lever. The spring 44, which is secured at one end to the lever 35 at a point above the shiftable device, has its free end fitted in a central notch 49 of the upper end of the said device. The shiftable device may be in the form of a shaft 50, provided with opposite loops or arms 51 and 52, as illustrated in Fig. 9 of the drawings, or any similar construction may be employed, as the shiftable device consists essentially in oppositely disposed sides or wings normally held at an intermediate position and arranged to successively engage the side levers.

After each operation of the gate the intermediate lever is automatically swung rear- .wardly by a coiled spring 53,'and when it is swung forwardly by either of the operating connections 54 and 55, the shiftable device engages the rear one of the side levers, and is forced laterally through such engagement against the proximate side of the lever 35, forming a rigid engaging member for actuating such side lever, which is carried forward with the lever 35, thereby oscillating the horizontal lever 29 and opening or closing the gate. This movement of, the shiftable device also carries its other side or wing clear of the other side lever, which is moved rearwardly as the intermediate lever swung forwardly. The intermediate lever is returned to its initial position by the spring 53, and the shiftable device is caused to assume its normal position through the action of the spring 44. This will cause the shiftable device to engage and actuate the otherside lever at the next operation of the gate. The side levers are provided at their upper ends with inwardly projecting lugs 54%, which are grooved at their rear faces, as clearly shown in Fig. 7 to engage the sides or wings of the shiftable device.

The coiled spring 53, which is arranged at an inclination when the lever 35 is at the limit of its rearward movement, is secured provided with a lug 56 for the attachment ofthe lower end of the spring, and the upper end of the latter is secured to an Lshaped plate 57 which is carried by the lever 35. The lower end of the bar or men1- her 55 is equipped with a cross piece 58,

which is bolted to lugs 59, projecting from the inner faces of the arms 3st and located above recesses in which the terminals of the cross pieces 58 are fitted. The bar or memher is curved at its lower portion and its upper portion is inclined to form a stop for the lever 35.

The operating connection 54, which may consist of a wire, or other suitable connec- 20.tion, is provided at its outer end with a chain 60, extending over a guide pulley 61 of a post or upright 69 and carrying a depending handle 63, adapted to be grasped by the operator for oscillating the lever 35.

The chain 60 is equipped with a stop ring 64 for limiting the backward movement and stop of the lever 35 by engaging the bracket 65 in which the pulley 61 is mounted. The other operating connection 55, which is designed to extend to a suitable post or upright (not shown), is equipped at its inner end with a chain 66, extending from the lever to a pulley 67, mounted on an inclined bar or member 68, secured at its lower 35 end to the inclined arm 32 of the supporting bracket. The chain is equipped at its outer portion with a stop ring 69, arranged to engage the bracket 70 in which the pulley (57 is mounted. Each of the operating connections is adapted to swing the intermediate lever 35 towards the inclined supporting bar or member 68, and as one inward movement of the lever 35 opens the gate and the next inward movement closes the gate, it will be apparent that the gate may be opened and closed from either side by the use of the single operating connection, thereby avoiding the confusion resulting from the employment of a pair of operating ropes at each side of the gate.
