AH e sir v In'venior UNITED STATES PATENT OFFICE.
JAMES WHEELER, OF RED OAK, MISSOURI, ASSIGNOR TWO-THIRDS, TO THOMAS HAGLER AND JAMEST. WILLIAMS, BOTH OF SAME PLACE.
GATE.
SEECIFIGATION forming part of Letters Patent No. 292,455, dated January 22, 1884.
' Application filed July 13, 1883. (No model.) I
To all whom it may concern;
Be it known that I, JAMEs'WHEELER, of
Red Oak, in the county of Lawrence and State of Missouri, have invented certain new and useful Improvements in Gates; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure 1 is a plan view, showing the various positions of the gate, the arrows indicating its movements. Fig. 2 is a side view, showing the gate open and-in elevation. Fig. 3 is an end view, showing the gate shut and in elevation. I
This invention relates to improvements in swinging gates, more particularly to those which are operated by sprocket-wheels and chains; and the invention consists in the construction hereinafter set forth and claimed.
In the annexeddrawings, the letter Adesignates a barred gate, and B B its posts. The inner post or turning-stile, G, of the gate is reduced in size at the top, as shown at c, and on this is keyed or otherwise secured the cylindrical blbck D, having the two sets of teeth d '01, forming a double sprocket-wheel. The post 0 is pivoted to the post B at c c, the upper pivot, 0 being below the sprocketwheel D.
Arranged around the sprocket-wheel D and to engage the teeth d d are two chains, E E, which are secured at their ends to the operating-cords F F, leading to the levers F E, which last are pivoted to the top of the posts G G, placed at convenient distances from the gate on each side.
Secured to the lower part of the wheel D, at or near its bottom, is a cord, H, which is also connected to the upper end, h, of an elbowlever, h, pivoted to the gate at h. .The lower end, h of this lever is secured to the gate- 5 latch K, and is furnished with a roller, is. This latch K is pivoted on the pin if, and to it is secured one end, Z, of a spring, L, the other, Z, of which is secured to a bar, a, of the gate. The curved portion of the spring L bears on the roller is, thereby being easily compressed as the-latch K moves up. This spring, when in its expanded position, holds the latch K down.
To open the gate, one of the levers is moved, and through the chain E the sprocket-wheel D, and with it the gate is turned. As the wheel D turns it pulls on one of the cords H, pulling down the upper end, h, of the lever h, lifting the latch K against the spring L, when the gate is unlatched, and a further pull opens i.t. After passing through the gate, a movement of the other lever returns it to place.
I am aware that a swinging gate has been provided with a sprocket-wheel operated by chains, such sprocket-wheel being secured to a pin on the side of the turningstile, and operating by a cam to move a sliding latch.
Having described myinvention, what I claim The combination of the posts B B, the turning-stile O, having the reduced end 0, the double sprocket-wheel D, secured on such end a, the chains E E, cords F F, operating-levers F F cords H H, elbow-lever h, latch K, pivv7 5 oted to the gate, and spring L, all constructed, combined, and arranged as and for the purpose set forth.
In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
JAMES WHEELER.
