GATE-ACTUATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 349,869, dated September 28, 1886.

Application filed April 24, 1885.

To all whom, it may concern.-

Be it known that I, WILLIAM RICHARD IVHITE, a citizen of the United States, and a resident of Neoga, in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in Gate- Actuating Mechanism, of which the following is a specification.

My invention relates to that class of gates in which a vertically-reciprocating bar is the means of communicating motion from the operating-lever to the gate; and the invention consists in the constructions and combinations of parts, substantially as hereinafter set forth.

In the drawings, Figure 1 is a side elevation of a sliding gate illustrating my improvement.

2 is an end elevation.

For the purpose of illustrating my invention I have shown it in connection with agate having an extended upper rail, a, sliding upon guide-wheels b b, turning upon pins projecting from standards A B, and supporting the gatepanel D, which slides back and forth across the roadway to and from the post E. The standard A is provided with a crosspicce. O, to which are pivoted the operating-levers F I The operating-levers are connected at their inner ends to the vertical]y-reciprocating bar G, the connection, as shown, consisting of a pin, 0, extending from the bar through slots in the ends of the levers; but any other suitable connection may be employed whereby the swinging of the levers upon their pivots is made the means ofreciprocating the bar, and the said bar is connected at the lower end to a connecting-rod, f, pivoted at its lower end to the gate-panel, so that the downward pull of the outer end of either lever F will be the means of swinging the gate back and forward, as set forth in the Letters Patent granted to me May 23, 1882, No. 258,517. In the class of gates illustrated in said patent the bar G slides in guides supported by the standard A, and these are apt to become rusty, and when oiled to become clogged and gummed with oil and dirt, so as to create considerable friction and interfere with the movements of the gate. Another disadvantage arising from the use of the guides is the rapid wear both of the guides and the reciprocating rod. In order to overcome these disadvantages, I connect the rod G pivotally to the ends of two or more parallel arms, h 71-, pivoted at their rear ends to a suitable support-as, for instanee,thestandard B which arms rise and fall with the bar G as SerlalNo.163,313. No model.)

it is operated by thelevers F, but without any other friction than the very limited friction arising from the swinging of the arms h upon their pivots. The arrangement above described not only avoids the friction resulting from the use of guides, but also prevents the increase of friction resulting when oil or other lubricant is employed when the roads are dusty, while the whole arrangement is much more durable than the rods sliding in guides, as heretofore. The arms It may be pivoted to any suitable stationary part of the gate, and may be arranged behind the bar G, as shown, or at either side of the same parallel to the roadway, and in order to prevent them from swinging laterally they may be extended between the side of the standard and a strip, 8, fixed at a short distance from the same, as shown, which strip does not interfere with their vertical movement, but prevents them from sagging laterally.

\Vhile I have illustrated the bar G in connection with a sliding gate and rod, f, I have done so for the purpose of illustration only, as the guiding-links or rod-arms It may housed in connection with vertically-moving rods arranged to operate gates of different characters through the medium of j ointed arms or crankarms, or any of the usual operating appliances. The bar G may also be used in connection with a single operatingarm, F, arranged in any suitable manner.

Without limiting myself to the precise construction and arrangement of parts shown and described, I claim 1. In a gate, the combination,with the vertical standards A B, each carrying rollers upon which the gate slides, of a reciprocating bar, G, connected by a pitman to the gate, and a pair of parallel arms, 71, pivoted at one end to the standard B and at the other to the bar G, substantially as described and shown.

2. The combination, with the vertical standards A B, the sliding gate, the reciprocating bar G, and the pitman f, of the parallel links it h and the strip 8, substantially as described and shown.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

IVILLIAM RICHARD IVHITE.
