ABRAHAM L. PIERCE, OF ASHAWA, IOWA.

FARM-GATE.

SPECIFICATION forming part of Letters Patent No. 246,338, dated August 30, 1881.

Application filed July 5, 1881.

To all whom it may concern Be it known that I, ABRAHAM L. P11111013, of Ashawa, in the county of Polk and State of Iowa, have invented an Improved Farm- Gate, of which the following is a specification.

The object of my invention is to' provide a gate-operating device that is simple, cheap, and durable, and that will diminish the power required for operating a gate from a passing vehicle.

Heretofore hand-levers of the first order, a miter-lever, rods, a triangular plate, and a spring-latcl'i have been so arranged and combined with a swinging gate that it could be operated from a passing vehicle; but as the handlevers have to be mounted upon posts set at a distance from the gate, and being but of the lirst order, makes it hard to operatea gate from a vehicle. To obviate this difficulty I arrange and combine compound hand-levers, a bellcrank lever, an arm, a spring, a sliding latch, conneeting-rods, and a gate as hereinatter fully set forth.

Figure 1 of my accompanying drawings is a top-plan view of my gate and operating device. Fig. 2 is a perspective view of the same. Together they clearly illustrate the construction and operation 01' my complete invention.

eis a block or arm rigidly fixed upon the 1 top and rear end of the gate Zr.

frepresents an arm that projects in an inclined position from the gate. It is rigidly secured to the end of the block 0 and the top board of the gate.

g represents a bell-crank lever pivoted to the free and top end of the arm f. It has an extension, 9, that projects outward and downward, and is adapted to prevent the crank-lever gfrom drawing on the latch of the gate as it is closed, and also restricts the movements of the hand-levers, so that they will always be in the right position for operating the gate.

9 is a metal strip pivoted to the crank-lever g.

h is a sliding latch, that has its bearing formed in or attached to the front end of the gate.

h is a spring rigidly secured to the lower portion of the gate, and connected at its top with the rear end of the latch h.

t'is a rod that connects the latch with the crank-lever g.

l is a rod that connects the opposite end of the strip 9 with the long arm of the lever 70, near the handle.

' m is a long rod that connects the long arm of the lever 10 with the short arm of the lever k. (Jonneotingtheleversinthismannermakes each of them a lover of the tirst and also of the second order to produce compound levers, by means of which the power required to operate the gate is greatly diminished.-

I claim as my invention- The arrangement and combination of the compound levers h /t", the bell-crank lever g, having extension g and pivoted strip or plate 9, the latch h, the spring h, the rod 'i, and rods l l m with a gate having a rigid arm,f, substantially as shown and described.
