Tlli. URAPIHC CBJLY- To all whom it may concern.'

Be it known that I, JOSEPH S. WINsoR, of Providence, county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Gates; and I- hereby declare thatthe following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, forming part of this specification.

Swinging gates asheretofore constructed are defective, for the reason that the sections of the gate, when in a closed position, are lo cated so near the surface of the roadway or crossing that the free operation ofthe gate is seriously impaired by the accumulation ofdirt, ice, snow, and the like, against the gate-,sections. Again, swinging gates have been furnished with counterbalance-weights; but such Weights have been arranged in such a manner as not to preserve the same relative position to the gate during its entire movement, and serve to balance the gate in any position it might assume.

The drawing represents a part vertical side elevation of my improved gate.

The object of my invention is to provide a vertically-swinging gate forrailroad-crossings, ferries, streets, farms, the swinging bars of the gate being constructed to be practically balanced or equipoised, whereby the bars may be readily raised and lowered with the expenditure of the minimum amount of power. Again, another object to be attained by my invention is to connect the vertically-swinging gate-bars by suitable actuating mechanism, in such a manner that both bars may be actuated simultaneously from any given or desired point.

The invention consists, rst, in the combination of two verticallyswnging gate-bars with suitable intervening mechanism, whereby both bars may be operated simultaneously; second, inthe several combinations of parts, as will be hereafter described, and pointed out in the claims.

In the drawing, A A represent the vertically-swinging gate-bars, which are pivoted at p pto the posts-or standards B B, the latter being located on opposite sides of the passage or roadway to be provided with my improved 'UNITED STATES PATENT OFFTG'E.

IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 151,260, dated` May 26, 1874;` reissue No. 7,45 l, dated December 26, 1876; application filed August 29, 1876.

gate. The swinging gate-bars are pivoted to the-standards B B, so that the distance from the pivotspp to the inner ends of the bars shall be considerably greater than the length ofthe outer ends of the bars, which latter are weighted, or constructed to practically counterbalance the inner and longer ends of the bars.

The gate-bars, in opening and closing, move in a-vertical direction, and, by reason of their being counterbalanced by weights M, may be operated with great facility, and by the expenditure of very little power. In order that both bars may be operated simultaneously, thereby rendering it only necessary to em ploy a single person to attend or operate the gate, the bars or arms are connected by the following mechanism: Wheels or pulleys W W are rigidly secured to the pivots or shafts p p, upon which the arms A A have their bearings. Chains c c pass over the wheels W W, and around guidesheaves o o, journaled in the lower portion of the standards B B, the ends of the chains being secured by means of rods r', located in the trough or underground tunnel I.

It will be observed that when motion is imparted to one of the swinging bars A, the opposite bar will he operated simultaneously through the medium of the underground connecting mechanism `described.

I prefer to construct the ends of the bars A A substantially as shown in the drawings at H-namely, to provide the meeting ends with mortise and tenon, whereby the ends will, of themselves, form a truss-support, and hence be rigidly locked together when in a closed position. In order to further support the bars A A, hinged supportsd d are secured to the bars, and when the latter are raised the supports d d fold against the edges of the bar. When the bars are lowered, the supports d d gradually unfold, and'flnally rest on the roadway, thereby constituting columns for the support of the arms or bars.

The counter-weights M are of such weight, or are secured to the short arm of the bars at such a relative distance from their fulcra, that the bars will be equipoised in whatever position they may be adjusted, and the same re-V sult would be secured it' the counter-balance were suspended from or overa segment attached to the gate-bars, provided the line of suspension was in line with the bars, as in such case the Weights would act as if their centers of gravity were at such points of suspension. A

Gates constructed in accordance with my invention may be adapted for any width of roadway or crossing. rlhe swinging bars are light in construction, and, owing to the fact that they are practically counterbalanced, they are enabled to be operated with ease and rapidity. Another important feature of' my invention consists in the fact that the bars are not hindered in their action by the accumulation of dirt, ice, snow, and the like, about the working or moving parts of the gate, as all such portions of the gate are eectually protected and inclosed by the standards and trough within which the actuating and con necting mechanism is arranged.

The gate is especially adapted for use at streetcrossings of great width, as the swinging bars may be made very light in Weight, and both bars easily operated by a single attendant.

Having fully described my invention, what I claim as new, and desire to secure by Letters Paten t, is-

l. The combination, ywith posts or standards B B, located on opposite sides ofthe gateopening, of vertically-swinging gate-bars A A, pivoted to shafts secured to standards B B, the gate-bars A Av having their shorter ends weighted, to practically counterbalance the longer ends, substantially as and for the purpose set forth. l 2. The combination, with posts or standards B B, located on opposite sides of the gateopening, of' the swinging gate-bars A A, pivoted tosaid standards, the bars A A provided with weights M, to practically counterbalance the gate-bars, substantially as and for the purpose set forth.

3. The combination, with two counterbalanced vertically-swinging gate-bars, of intervening mechanism, substantially as set forth,

whereby both bars may be retained in any desired position and actuated simultaneously, substantially as and for the purpose set forth.

4. A gate consisting of two verticallyswinging gate-bars, connected by intervening mechanism, whereby they may be operated simultaneously, said bars being constructedV so that their inner ends shall interlock with each other when thegates are closed, substantially as and for the purpose set forth. l

5. The combination, with the connterbalanced vertically-swinging gate-bars A A, pivoted tov the posts or standards B B, of the connections c r, pulleys a w, and sheaves o o, substantially as and for the purpose set forth.
