FITCH RAYMOND, OF CLEVELAND, OHIO.

Letters Patent No. 101,765, dated April 12, 1870.

IMPROVEMENT IN GATES.

*4. l The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, FITCH RAYMOND, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain newA and Improved Gate; and I do hereby declare that lthe following is a full, clear, and complete description ofthe same, reference heilig had to the accompanying drawings making part of this specification, in which- Figure 1 is a side view of the gate.

Figure 2, a view of the top.

Figure 3, a detached section.

Like letters of reference refer to like parts in the several views.

The objectthis invention h'as in View, is a selfclosing gate.

The devices employed for the purpose consist of a chain, the links of which are so connected to eachv other that the chain can be deflected from 'a1-ight line' to a circleoi` a certain diameter, and no less, one end of said chain being attached tothe gate, whereas the other is attached to an ordinary chain or rope falling over a sheave to the ground, and to the end thereof is attached a weight, all of which is more especially desclibed hereinafter.

In the'drawing- Fig.-1, A, represents a post, to which the gate B is hung by a pair of ordinary hinges, O. A top view ot' the upper hinge is shown in tig. 2.

To the upper rail D of the gate is secured an arm,

n E, iig. 2, to which is attached one end of the chain F,

whereas the opposite end of said chain is attached to an ordinary chain or rope, G, received into a tube, H, into which it falls over a sheave, a, by being attached to a weightin the lower andlarger end 0f the tube.

The peculiar construction of the 'chain F is such that, when deected from a right line in one direction, it will describe a. circle of a certain diameter, and a circle of no less a diameter, for the reason that the shoulders I, fig. 3, near the articulations of the links, will come together, as shown in g. 2, thereby preventing a quicker curvature of the chain.

The application of said chain to the gate is shown in tig. 1, in which it will be seen that one end thereof is attached to the arm E,.whereas the length of the chain extends .back to the end .of the tube. ln this position of the chain it is straight, and the gate closed, as seen in the drawing, fig. 1. `N ow, on pushing open the gate, as shown in iig. 2, or less, the chain F will be drawn around by the arm E, and, in consequenceI of the closing together of the shoulders I, the chain will describe a circle concentric with the hinge C, and each pivoted articulation c ofthe' chain will be equidistant from the hinge.

By this it will be obvious. that the draft exerted uponthe gate, by the weight attached to the end of the chain or cord G, will have a leverage power upon the gate equal to the distance that the pivot of the arm E is from the hinge, and will therefore cause the gate to swing back and close, as shown in iig. 1.

This manner of closing the gateis-simple and certain in its operation, and can be readily applied to all gates hung on an ordinary hinge.

The weight attached to the end of the cord for drawing the gate fast may be used'withont the tube, if so desired.

In the event that the tube is used, it is sunk into the ground, and, being made tight, it will be free from water or dust, so that the weight will move freely therein. If used without saidtnbe the-cord is run up over a sheave secured to a. post, in order to obtain a sufficient length of cord to allow the gate to swing open.

C lat'm.

What l claimy as luy-invention, and desire to 'secure by Letters Patent, is

lhe chain F, constructed with joints C and shoulders I, in combination with the arm E, gate B, and cord G, arranged and operating conjointly, substantially as and for the purpose set forth.
