birdied %istez LEVI S. DEMING, OF NEWINGTON,CONNECTICUT.
Letters Patent-N0. 91,723, dated 11011622, 1869.
IMPROVEMENT IN GATES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern dicnlar. shaft, arranged underneath the gateway,'the
lower end of which takes its bearing and vibrates in a fixed step, while the upper end is steadied in one direction by a vibratory arm, and is supported in the otherdirection by the gate-connections, so that as the approaching carriage-wheel strikes the brake in the common way, its connection causes the shaft to turn, first in one direction, then in the other, this shaft also being provided with a projecting weight, so that as it (the weight) passes the perpendicular line, it throws the upper end of the shaft into an incline position, and imparts force, and accelerates the action of the gates, to open or close by means of the common connection. I g
It further consists of an arm or notched wheel, secured. upon said shaft, and acts upon an eccentricweighted lever, which with its connection depresses the'thsteuing which holds the gates closed, and allows the gates to freely open.
In the accompanying drawings.-
Figure l is an elevation of the actuating-mechanism of this invention.
Figure 2 is a top view of the connections secured to the lower end of the gates, and to the upper end of the shalt.
Figure 3 is a view of the gates, showing the fastening by which they are held in a closed position.
Figure 4, sheet 2, is a side elevation of the actuating-mechanism.
Figures 5, (i, 7, and 8, are views of detached portions thereof.
a is a shaft, the lower end of which takes bearing in a fixed step, b, underneath the gateway. The upper end of this shaft is held in nearly a perpendicular position, in line li'oin one side of the gateway to the other, by an arm, 0, one. end of which is secured to the upper end of the shaft (1, and the other end to the frame-work or stud. under the driveway. Thus, this shaft is held nearly in a perpendicular position, crosswise of the drive-way.
(I is a connection-plate, or arm, secured to the upper end of the shaft a, the ends of which are, or may be bent or formed at right anglos therewith, and pe|fo rated to receive a screw-threaded connection, 0, so that its length, or position of the shaft a may be adjusted by means of untsfor hooks, 8270.
g is a s\vivcl-connectioii, for uniting the opposite portion of the chain or rod-connections, and for the purpose of taking up or letting outone side or the other, as desirable, to nicely adjust the action of the mechanism,
The chain-portion h of these connections passes around the lower end of the gate-shaft i, and is secured thereto by a screw, or staple, k, which completes the connection of the upper end of the shaft a with the shafts i of the gates.
j is a weight, secured to a projecting arm of the shaft a. I This weight maybe cast on to one side of the shaft, or made adjustable on the arm, by means of a keysorew, or other suitable means. The object of this weight is to give force, and accelerate the action of the gates, as it (the shaft a) rotates and passes a perpendicular line, into an incline position in either direction,
in opening or closing the gates.
The rotating action of this shaft it throws the weight j, first from an incline. position, one side of a perpendicular line, into an opposite incline position, the other side of a perpendicular line, the tendency of whichis to hold the gates either open or closed, until again operated upon by the brake, in the common way.
The rotary action ofthis shaft ai's produced from the brakes in common use, by connections passing around said shaft, and secured thereto substantially as show at A, fig. 2.
Ncar the lower end of this shaft ais'sccured an arm, or notched wheel, I, and so arranged thereon, that when the shaft commences to rotate, the arm or notch or will lift the weight or outer end a of the cocentric lever 0, which, by its connections 0, depresses the gateastener 12, and allows the gates to freely open, by the continued action of the shaft and weight a j. And when the brakes again act upon the shaft to close the gates, the lever o, by means of the weights will lift the fastener, so that the gates, as they close, willride over said fastener, and be firmly held in a, closed position, until again acted upon as before.
The same principle-of a weighted lever, I purpose to attach to the gate, so that the fastener may be actuated or depressed, by a foot or hand, to open the gate. I
The other portions of the mechanism for operating or completing the gate are like those in common use.
I will not further describe.
I believe I have thus shown the nature, construction,'and advantage of this invention, so as to enable others skilled in the art to make and use the same therefrom.
\Vhat, 1 claim, therefore, and desire to secure by I nection o, gate-fastening 12, arranged and operating substantially as and for the purpose described.
