No. 645,359. Patented Mar. 13, I900. W. HATFIELD & J. P. TARB.
GATE.
(Application filed Dec. 28, 1899..)
(No Model.)
UNITED STATES PATENT OFFICE.
\VALLAOE HATFIELD AND JOHN P. TARR, OF AUGUSTA, ILLINOIS.
' GATE.
SPECIFICATION forming part of Letters Patent No. 645,359, dated March 13, 1900.
Application filed December 28,1899, Serial No. 741,838. '(No model.)
To aZZ whom it nmy concern:
Be it known that we, WALLACE HATFIELD and JOHN P. TARR, citizens of the United States, residing at Augusta, in the county of Hancock and State of Illinois, have invented certain new and useful Improvements in Gates; and we do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.
The invention relates to gates, and more particularly to farm-gates.
The object of the invention is to provide a simple, durable, and inexpensive gate which may be easily operated.
To this end the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described andclaimed. 1
In the accompanying drawings, Figure l i a perspective view of the gate, showing it closed. Fig. 2 is a side elevation showing the gate open.
In the drawings the same reference char-- acters indicate the same parts of the in vention.
1 and 2 denote the lever-posts, to the former of which the gate 3 is hinged.
4 denotes the fence or latch post.
5 denotes a rock-shaft pivoted to the posts 1 and.2 and extending at right angles to the gate when it is closed. This shaft is provided with a weighted arm 6 and with a crankarm 7.
8 denotes operating-levers pivoted to the posts 1 and 2 and connected to the crank 7 by links 9.
1O denotes adiagonally-extending arm fixed to the rock-shaft 5 and loosely connected to the gate 3 by a link 11.
12 denotes a stop-block secured to the side of the post 1 and adapted to be engaged by apin 13 on the end of the shaft 5 and limit the movement of the shaft, and thereby prevent arm 10 and link 11 from falling below a deadcenter to the line of movement of the gate.
1 L denotes the pull cords or ropes connected to the outer ends of the levers 8.
Assuming the gate to be in the position shown in Fig. 1 and it be desired to open it, one of the cords 14 is pulled down, which will elevate the inner ends of the operating-levers, which being connected to the rock-shaft 5 bythe link 9 will rock said shaft and elevate the weighted arm 6, and the momentum of this arm will carry it past the dead-center, and thus the weightof said arm will continue to draw the gate open until it strikes the post 2, in which position the weighted arm has been swung on the otherside of the rock-shaft. To close the gate, one of the levers is actuated in the same way, thus throwing the arm around in a reverse direction until it has passed a V61 tical position, when it will by its own weight force the gate closed.
From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of our improved gate will be readily apparent Without requiring an extended explanation.
It will be seen that the gate is simple of construction, that said construction permits of its manufacture at small cost, and that it is exceedingly well adapted for the purpose for which it is designed. I
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. c
Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is-
The combination with a hinged gate and its lever-posts, of arock-shaft journaled between said posts and provided with a weighted arm, a crank and adiagonal arm, a link connecting the diagonal arm to the gate, operating-levers pivoted to said posts, links connecting the in ner ends of the operating-levers to the crankarm, a block secured to one of the said posts, and a pin projecting laterally from the rockshaft and adapted to engage said block and limit the movement of the rock-shaft in the closing of the gate to retain the diagonal arm and the link connecting it to the gate at a deadcenter to the path of movement of said gate, substantially as and for the purpose set forth.
In testimony whereof we have hereunto set HGSSGS.
