PATENT #.fEEicE.
DAKOTA TERRITORY, ASSIGNOR OF ONE-HALF TO ALPHONSO W. HAGER, OF SAME PLACE.
EVENER-'SPRING FOR WHIFFLETREES.
SPECIFICATION forming part of Letters Patent No.319,9617 dated June 16, 1885.
Application led March 2S, 1885. (No model.)
To all whom, it may concern:
Be it known that I, EDWARD G. CURREY, a citizen of the United States, residing at Mitchell, in the county of Davison and Territory of Dakota, have invented a new and useful Machine or Mechanical Device known as a Whiflletree-Evener Spring, of which the following is a specification.
My invention relates to draft-equalizers;
A1o and it consists in a spiral spring secured to a metallic frame above orbelow the vehicle pole or tongue, or attached to a harrow or other machine in any suitable Way.
It further consists in details of construction and operation of the several parts, as will be hereinafter more fully set forth in the specification, and pointed out in the accompanying drawings.
The object of the device is to reduce the 2o shock or jerk upon the shoulders of animals when engaged at work and equalize the strain. These objects are attained by the device shown in the accompanying drawings, in which- Figure l is a longitudinal vertical section of my device; Fig. 2, a top view of the iron eye-plate attached to the front side of the whiffietree-evener to receive the evener-bolt; Fig. 3, a vertical section of the rear headplate and the supporting tongue or pole; and 3o Fig. 4, a vertical section of the device for at tachment to plows, harrows, &c.
Referring more particularly to the drawings, in Fig. 1 Il have shown the spiral spring E in position and held iu place by a plate, 3 5 O, having a continuous slot in which the bolt B and head-plate I move. A similar slot is provided in the lower plate or tongue or pole. The bolt-socket attached to the front of the evener is round on its front-face and bears on 4o the head ofplate I on its center all the time, and thus insures an even and direct bearing on the spring. The evener pivots on this bolt which is in the socket having a round front, and it is evident there can be no other than a center 4 5 bearing, whichever end of the evener is ahead. I thus insure the bolt and head-plate moving in a straightline forward and backward, as well as assisting to keep the braces F G in position.
I also avoid a difficulty experienced in other forms of eveners, in which if either end of the 5o evener is drawn one foot ahead, (asis very commonly the case,) the spring would break off; or if it did not at first break it would become so twisted that it would stay in place but a short time. A guard, N, holds the spring in posit-ion along the sides. A buffer, L, of rubber, gutta-perCha, or other suitable material, serves to take up the shock and strain caused by the evenerl A after the compression of the spring E. I may use a metallic spring 6o for a buffer instead of the rubber, Ste., just described.
When the device is attached to plows, harrows, and other implements of like character, or horsecars,where no tongue or pole is used, 65 I attach the evener A to the rod Q, Fig. 4, which passes lengthwise through the springE and is fixed to the head-plate Rat the rear end of the spring. Back of this head-plate is a buffer, L, against which the head-plate strikes 7o upon its return after the compression of the spring. The head of rod Q cornes in contact with a buffer, X, upon its return movement. By means of the ring T and bolt U, I am enabled to attach the device to cars, harrows, &c. The spring is held in position and moved between the upper and lower plates, Y, and the side plates, Z. These side plates are secured to the end pieces, W.
The device is simple and durable, and can 8o be easily attached to any vehicle or implement and be readily removed therefrom when necessary.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a draft-equalizer, the combination, with the evener, of the spiral spring, the slotted holding-plate, a bolt and head plate moving in a slot in said holding-plate, the bot-socket, 9o the end braces, guard, and buffer, substantially as and for the purpose set forth.
EDWARD O. CURREY.
