MULTIPLE EVENER.

SPECIFICATION forming part of Letters Patent No. 759,361, dated May 10,

. Application led January 18, 1904. Serial. No. 139,588. (No model.)

T0 all whom it may concern,.-

Be it known that I, CHARLES L. FowLE, a citizen of the United States, residing at the city of Dowagiac, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Multiple Eveners, of which the following is a specification.

This invention relates to improvements in multiple eveners.

It relates to three and four horse eveners and toany number of eveners for more than two horses. It is especially adapted for use on graindrills,although the same can of course be made use of on other machines of similar draft construction, particularly those having two poles, such as large iield-cultivators and the like.

A serious difiiculty with three and four horse eveners as heretofore constructed has been to secure them in substantially a level position and yet permit all of the'freedom of movement necessary to secure the desired equalizing action.

This invention has to do with providing improved means of'properly supporting in position a three and four horse evener, so that its movement is considerably restricted without in any way interfering with its eflciency and with its weight suspended intermediate its coupling to the machine and harness-coupling to the eveners and having sufficient clevis action to allow the eveners to swing freely into line of of draft with the tugs of the harness, thereby causing a straight line ofdraft from the harness-llames tothe coupling of1 eveners with the machine.

Objects relating to the details of construction will fully appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. l

The invention is clearly dened, and pointed out in the claims.

A structure embodying the features of my invention as applied to a four-horse evener is clearly illustrated in the accompanying drawings, forming a part of this specification, in which- Figure l is a detail view of the improved evener in its lproper relation to the framework and tongues of a grain-drill, portions of the timbers being broken away. Fig. 2 is a detail sectional elevation View taken on line 2 2 of Fig. l.V Fig. 3 is an enlarged detail sectional view of the main clevis taken on line 33 of Fig. 1. Fig. 4. is an enlarged detail sectional view taken on a line corresponding to lines 4 4 of Figs. l and 2.

In the drawings the sectional views are taken' two tongues A' A and is connected by the usual or any suitable clevis B to the main evener B. This main bar is connected by a suitable clevis or suitable pivotal connections to a pair of doubletrees of any usual construction at each end, the doubletree-bar C C being connected by suitable pivots to the swingletrees c c at each end.

The pivoted bolt a, which connects the main evener-bar to the doubletree, is provided with an eye at its upper end, to which is connected the supporting-chain a'. The upper end of the supporting-chain is secured to an elongated rod-loop a, the main body of which is slightly inclined so as to allow the evener to drop down a little as it is swung back. This rod a extends through the upper link of the supporting chain a'. This, it will be seen, allows a complete freedom of movement back and forth of the main evener-bar B', and yet properly supports within the limited range of movement up and down the doubletrees at each end of this main evener-bar. Owing to the fact that the loop c is elongated, the movement back and forth is amply provided for. By this means the evener is as effective as it VIO would be if left entirely free at each end. and at the same time its movements are entirely confined within any desired limit, the desirability of which is obvious when the necessary size and length of these devices is taken into consideration.

Any linkconnection between the doubletrees and the loop a would serve the purpose, although the chain is obviously the best and most convenient.

Details of this structure can obviously be modified indefinitely within the range of art of improvements in Whiletrees, the details of the construction of the evener itself, aside` frolm the supporting means, being immateria Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a multiple evener, the combination of a frame; 'a draw-bar connected to the frame; a main evener-bar connected by a suitable clevis to the draw-bar, doubletrees at each end of the evener-bar; the pivot-bolts of which are provided with eyes at their upper ends; poles A A extending above the ends of the main evener-bar with an elongated rearwardly-inclined loop a on the under side, and a chain a connected to the eye `on the doubletree-bolt and to the loop a so that it is freely movable along the same, coacting for the purpose specified.

2. In a multiple evener, the combination of a frame; a main evener-bar connected by a suitable clevis; doubletrees at each end of the evener-bar, the pivotal bolts of which are'provided with eyes at their upper ends; poles A' A extending above the ends of the main @vener-bar with an elongated rearwardly-inclined loop a on the under side, and a chain a connected to the eye on the doubletree-bolt and to the loop t so that it is freely movable along the same, coacting `for the purpose specified.

3. In a multiple evener, the combination of a frame; a main evener-bar connected by a suitable clevis; doubletrees at each end of the evener-bar, the pivot-bolts of which are provided with eyes at their upper ends; poles A A extending above the ends of the main evener-bar with elongated loop a on the under side, and a chain a' connected to the eye on the doubletree and to the loop a so that it is freely movable along the same, coacting for the purpose specified.

4f. In a multiple evener, the combination of a frame; a main evener-bar connected by a suitable clevis; doubletrees at each end of the evener-bar; poles A A extending above the ends of the main evener-bar with an elongated loop a on the under side, and a chain a connected to the doubletree and to the loop a so that it is freely movable along the same, coacting for the purpose specified.

y In a multiple evener, the combination of a frame; a main evener-bar connected by a suitable clevis to the frame; doubletrees at each end thereof; longitudinal loops connected to the frame above the doubletrees; a chain connecting the doubletrees and the end of the main evener-bar to thefloop so that the same may play freely backward and forward, for the purpose specified.

6. In a multiple evener, the combination of a frame; a main evener-bar connected by a suitable clevis to the frame; doubletrees at each end thereof; longitudinal loops connected to the frame above the doubletrees; and a connection for the doubletrees and the end of the main evener-bar to the loop so that the same may play freely backward and forward,

for the purpose specified.

7. In an evener, the frame; a main evenerbar connected by asuitable clevis to the frame; longitudinal loops secured to the frame above each end of the evener; and a chain connecting the ends of the @vener-bar to the loop so that the same may play freely backward and forward, for the purpose specified.

8. In an evener, the frame; a main evenerbar connected by asuitable clevis to the frame;

' longitudinal loops secured to the frame above each end of the evener; and a connection for the ends ofthe main evener-bar to the loop so that the same may play freely backward and forward, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
