To ALL WHOM IT MAY CONCERN:

Be it known that I, THEODORE MUNGER, of Jaynesville, in the county of Bremcr, and Stat-eof Iowa, have invented a new and improved Gate and Opener; and I do hereby declirre the following to be.a full,clear, and exact description of the same, reference being had to the accompanying drawings, forming part-of this specification,-and in which- Figure '1 is a side elevation of my invention.

Figure'2 is a top view of the same.

Figurefl-shows the red I and wheel in when made in the form of apinion and rack.

Similar letters of reference indicate corresponding parts in the several figures,

This invention relates to gates which open and sh'uthy sliding horizontally back and forth in a frame, and consists in applyingto them a cord, pulley, and crank-rod, for the purpose of'opening-aud shutting them; in a novel support for the crank-rod; and in a peculiar latch or fastening, operating in combination with the cord,

pulley, and crank.

Inorder that others skilled in the art to which myinventiou appertains may be enabled to make and use i the same, I will proceed to describe it in detail.

' In the drawings, A represents the sill, and B B B" the upright posts of a frame which supports the gate, and which extends across the i'oad, being connected at one end with the centre of another sill, C, which extends parallel with the road. At the extremities of the latter sill are upright posts -D 'D, provided with stout arms E E, strengthened by braces F F, and projecting towards the travelled way, to receive and support the crank rod H. The gate G- is an ordinarysliding gate, running outrucks a a, which are supported by the posts B B",

and guided and steadied by the guide-pieces 1/5; Alongjits top extends a movable red, I, sliding a few inches longitudinally by means ofits supporting-pin, p, and a slot, 8. I It is connected with the crank-rod Hby a cord,

0, which passes from its extremities over a grooved pulley, h, on the crank-rod, and enables the operator, by turning the cranks It It in either direction, to slide the rod I the length of'the slot 0, and after-that to slide the gate in either direction, so as to open'or shut it. m is aroller, upon which the gate rests when shut. A latch,

L, .is pivoted to theforward end of the gate, and provided with a spring, Z, to keep it in the proper situationto latch itself readily, and withau arm, Z, by which the latch is opened whenever the sliding rod I is drawn back till the pin i strikes the arm. A suitable keeper, K, is fixed to the post B, to operate in connection with the latch L. To strengthen the whole apparatus I would pass the crank-rod H through the post QB, making the latter-serve as an additional central bearing for the crank-rod. The bearings of the crank-rod, as well as the supports of the gate-itself, may be all made adjustable vertically, by being in separate pieces, attached to the posts by a set-screw operating in a slot, as shown at e e e". When this device is employed, the projecting arms E E and braces F F must be attached to the vertically-adjustable piece e'instead of the posts. This will enable the gate to beadjusted at any desired height from the ground.

Among the advantages which iny improved gate possesses. may be enumerated the following:

First. The projecting arms H H bring the cranks over the edge of the travelled path, and enable a person to drive his carriage close to them. When the crank-rod bears in the side posts themselves, it is diflicult to approach it in a carriage without striking the wheels against the posts; besides," the posts must necessarily be stationed outside of-the path, and one must drive outof his way to get within reach of them.

Secondly. The gate operates easily, smoothly, and without noise, and when shut, is very strong and firm.

Thirdly. The gate, when fastened, can be opened in two ways only: first, by unlatching it directly by hand and pushing itbaok, and secondly, by turning the crankrod, which operates first to unlatch, and secondly to open the gate. i

The spring l,.whioh holds thelatch in position, also serves, by pressing against the arm Z and pin 2', to keep' the sliding rod I always in position to be operated by a turn of the crank.

It is evident that a pinion may be used instead of the pulley'k, and the red I may be formedinto a rack to operate with the pinion. Theshaft H hearing at its centre in the adjustable piece e, the gate can be raised or lowered to clear snow or other obstructions'without the necessityof raising the crank shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The adjustable pieces 2 e e, in combination with the gate G, substan-tiallyas and forthe purpose shown.
