TO ALL WHOM IT MAY CONCERN:

B e it known that I, RALPH ADAMS, of Ottawa, in tho county of La Salle, and State of Illinoisl1ave invented a new and improved Gate; and I do hereby declare that-the following is a full, clear, and exact description thereof, which will enable those skilled inthe art to make and use the saine, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1 is a plan view' of my improved gate.

Figure 2 is a sectional elevation of the same through line .fc x', iig. 1.

Figure 3 is a sectional elevation of the Agate through the line y y', g. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved gate, which can be opened and closed by persons while onhorseback or in vehicles. l

' A A A are the bottom framing', which supports the gate and its operative mechanism. B is the gate. C the post, to which it is partially hinged.- D are the Alever-posts, having pivoted thereto thelevers-L by screwpivots a. A toothed rack, E, is conneetedjby rods of iron, R, to the levers by pivots ato'. This rack works in a slot cut in the post C, near its bottom, and is moved horizontally to the right or left through the said slot, according as the levers L L, to which it is connected, are actuated to the right or l'eft, and in so moving opens the gate, as will be now explained.

A half pinion, G, firmly Aattached to the hottom'ot` the upright, F, of the gate-t`rame, has its teeth presented to and engaging with the rack above described, so that when the levers are pushed, the rods R draw or push the rack, which latter, engaged as `aforesaid with the pinion Gon the upright F, forming part of the gate, B, opens or closes the gate. A rope or cord, m, passes through eyes z' on the levers and staples t, on the upright F, and thence downward and through the rear end n, of the latch-bar P. This latch-bar is vsupported on a. pivot, g, in'the gate-frame, and the end, c, catches upward into a notched plate, 7c, attached to .the post C', so that the rear end, n, ot' the latch-bar isgto be raised to disengage the said bar from its notchin the plate 7c. A spring, S, bears down the end, n, of the bar, and thus keeps the gate latched until the cord m is drawn. ThisV cord is not riven loosely through the end of latch-bar, as through the'other eyes and staples, but is tied or otherwise prevented from rendering when it is drawn; it therefore lifts the end, n, which lowersthe end, c. The lower pintle of the upright, F, is shown at g, having a step bearing in the plate u. The upper hinge consists ot a pintle, b, working in a plate, d, which is bolted to the post C.

In operating this gate, it is only required to ride up within reach of one of the levers L, 'and drawing the cord m till the latch-bar is disengaged from its notch, and then push with the same hand the lever; the gate will .then open from the person pushing. yIf the lever is pulled the gate will open toward the person pushing. A pawl, v, pivoted to one of. the levers L, near its upper end, traverses on the arc of a segmental plate, j, having a notch;f, in4 which the said pawl catches when the gate opens. This pawl has an arm, hy which itis pivoted to asmall lever-handle, Z, which latter is pivoted to the lever L, all as shown. One of these pawls, with its connections, is to be placed oneach lever L, and as the vone opposite to the person opening the gate is the one which catches after the gate has opened, so that when the rider or driver passes through he has only to libera-te the pawlby pressing on the lever Z, to shut the gate after he has passed through, the pawl on the lever he has left does not catch until the gate is opened toward it. i

The' advantagesiof my improved gate consist in the facility with which it is operated, its simplicity ot' construction, and small cost. Y

There are many gates provided with mechanism for being opened from a vehicle, but they are all more or less complicated, and generally get out of repair in a short time. My gate, having no complicated parts, is therefore not liable tobecome -inoperativeifrom ordinarywear, and will lastvfor years.-

I claim as nemend desire to secure by Letters Patent- 1. The levers L and rods B.,in combination with the rack E, substantially'as shown, for the purpose of opening a gate, all as set forth. i

A 2. The latch-bar l? and cord m, in combination with the levers L, substantially as shown and for the pui'- posespeciied.

3. The pawl n, in combination with the levers Z and L, and notchf, for the purpose of holding a gate open, substantially as shown. I

i RALPH ADAMS.
