To all whom, it may concern-.-

Be it known that I, WILLIAM ANDREW STREITMATTER, a citizen of the United States,

residing at Princeville, in the county of Peoria and State of Illinois, have invented a new and useful Automatic Gate, of which the following is a specification.

' The invention relates to improvements in automatic gates.

The object of the present invention is to improve the construction of sliding gates and to provide a simple and comparatively-inexpensive one capable of being operated at a distance from either side of it by a person in a vehicle or on horseback or on a bicycle without stopping and adapted after the actuating mechanism has run down to have the same readily wound up by a person driving through the gateway without leaving his vehicle.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed outin the claims hereto appended.

In the drawings, Figure 1 is a perspective view of an automatic gate constructed'in accordance with this invention and shown closed. Fig. 2 is an end elevation of the gate, the same being open. Fig. 3 is a side elevation of the same, partly in section.

Like numerals of reference designate corresponding parts in all the figures of the draw- Ings. I

1 designates a sliding gate, preferably composed of a Wooden frame and horizontal wires, the top bar 2 of which is extended rearward and is supported upon rollers 3 and 4 of uprights 5 and 6, whereby the gate is adapted to slide longitudinally in opening and closing. The gate is strengthened by inclined bracingwires 7 and 8, extending upward from the bottom of the gate and connected, respectively, to the front end bar and to the rear end of the top bar. The posts or uprights 5 and 6 are provided with suitable guide-pulleys 9 and 10, located above the supporting-rollers and retaining the top rail 2 of the gate thereon. The bottom of the gate is guided by a vertical roller 11, mounted on a suitable spindle or support and located adjacent to the post 5, which is provided with a wear-iron 12,

of the shaft.

. closed.

and forth, as will be readily understood. The

shaft 13, which is disposed horizontally, is journalcd in suitable bearings of a supporting-frame 16 and a bracket 17, and it carries a drum 18, around which is wound an actuating cord or rope 19, and a weight 20 is connected with the same and is adapted in falling to rotate the shaft. The cord or rope 19 extends upward from the drum and passes around a pulley 21 at the top of the supporting-frame, and a vertical casing 22 forms a Well for the weight and is adapted to protect the same and the rope from the Weather.

The drum, which is adapted to be rotated by the means hereinafter described for winding up the weight, is loosely mounted on the shaft, and is connected with the same by a clutch consisting of a ratchet-wheel 23, carried by the drum, and a pawl 24, mounted on a bar 25, which projects from opposite sides The bar 25, which is fixed to the shaft, forms a pair of arms which are adapted to engage alternately a resilient catch 26, whereby the shaft is locked at the end of each half-revolution to hold the gate open and The resilient catch 26 is mounted on an inclined bar 27, extending forward from the lower portion of the supporting-frame and connected near its upper end with the same, and the said catch, which is mounted on the inner edge of the bar 27, has its upper end bent at. an angle to form an arm to receii e the arms of the shaft. The bar 25, which is carried by the shaft, is held against retrograde movement to prevent the gate from having any recoil bya resilient dog 28, located above the catch 26 and mounted on the inclined bar 27. The inclined bar 27 of the supporting-frame is provided with a recess 29, into which the resilient catch is drawn to trip the actuating mechanism of the gate and cause the latter to be reciprocated. The tripping of the actuating mechanism is effected by means of operating devices 30, ex-

tending fromthe gate in opposite directions and having their outer portions supported by suitable posts or uprights3l. The operating devices pass over suitable guide-pulleys of the posts or supports 31 and extend therefrom to the supporting-frame, which is provided with pulleys 32 and 33, located at the outer edge of the inclined bar 27. The guidepulley 33 is located opposite the upper end of the catch, and when either of the operating devices is pulledthe said catch is withdrawn from its engagement with the bar of the shaft, whereby the latter is tripped and is permitted to rotate one-half a revolution. The supports or uprights are located a sufficient distance from the gate to allow the latter sufficienttime to open, so that a person within avehicle or on a bicycle may pass through the gateway without stopping. ,The operating devices, which may be constructed in any suitable manner, preferably consist of wires provided at the guide-pulleys with short chains 45 and 46.

.The rotating bar 25/ is arranged within guards 34 and 35, mounted on the supporting-frame and arranged as clearly shown in Fig. .3 and located beneath a vertical casing 35, which receives the supplemental weight 36. ,The supplemental weight 36 .isloosely connected with a winding ropeor cord 37, which passes over a pair of pulleys 38 and 39 at the top of the casing and which has its inner end wound around the drum in a reverse direction to that of theweighted cord or rope,

whereby when the winding cord or rope is drawn outward the drumwill be rotated to wind. up the weight. The weight 36 is connected with the cord or rope 37 at a point be.-

tween the pulleys 38 and 39, and it is adapted after the weight has been wound up todraw the slackofthe winding cord or ropeinto the casing35 toprotect it from the weather. The outer end of the winding cord or rope is providedwith a suitable grip 40 and is arranged beneath a guide-pulley41, located at the outer edge of the bar 27 in convenient position for a person passing through the gateway to readily grasp it, whereby the weight may be wound up without necessitating a person dismounting. I The gate when it is closed abuts against a supplemental gate 42, consisting, preferably, of a rectangular frame of wood and .a body portion of wires similar to the gate 1 and slidingly mounted on posts or supports 43, which are provided with upper and lower brackets 44. The brackets 44 have outwardly-extending L-shaped arms receiving the top and bottom bars of the supplemental gate, which is held in itsclosed position by a spring45. Any, other suitable form of latch may be employed for the supplemental gate, whichis adapted to be opened to permit the passage of a large load or a binder or other agricultural machine.

The invention has the following advantages; The gate, which is simple and comparatively inexpensive in construction, is' positive, reliable, and automatic in its operation, and it is capable of being opened and closed by persons within vehicles or on horseback or bicycles without dismounting. Also the gate actuating mechanism may be readily wound up as it runs down, and the winding operation may be performed by a person driv-' ing through the gateway without leaving his vehicle.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Thecombinationwith a slidi'nggate,,of a shaft connected with the same, was, connected with the shaft, a drum mounted, on the shaft, a clutch connectingthe shaft with the drum, mechanism for actuating the drum, a catch arranged to be engaged by thev arms of the shaft, and operating mechanism .c'on-- nected with the catch and adapted to trip the same substantially. as described. I
