HERMAN BASMUSSEN, OF SEDGWICK, SOUTH DAKOTA.

WI-IIFFLETREE.

Specification of Letters Patent.

Application filed May 5, 1913.

Patented Jan. 6, 1914.

Serial No. 765,629.

To all whom it may concern Be it known that I, HERMAN RAsMUssEN, a citizen of the United States, residing at Sedgwick, in the county of Hyde and State of South Dakota, have invented certain new and useful Improvements in VVhitlletrees, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to new and useful improvements in whitlletrees and more particularly to a whiffletree Which is constructed of sheet metal or other similar material, the object of the invention being to provide a whiftletree of the above character in which the pull upon the same will be equally dis tributed and not throw the strain upon any particular part thereof.

Another object of the invention is to provide a whifiletree of the above character which will possess advantages in points of efliciency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

lVith the above and other objects in view, this invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a longitudinal sectional view of a whiflletree constructed in accordance with my invention; Fig. 2 is a top plan view; and Fig. 3 is a transverse sectional view.

Referring more particularly to the drawings, 1 indicates the body of the whitfletree which is preferably constructed of sheet metal or other similar material and is substantially rectangular in cross section. Arranged at each end of the body are suitable blocks 2 provided with openings through which are adapted to pass the bolts 3, said bolts passing through the side walls of the body 1 and secured in position by means of the nuts 4 which are threaded upon one end thereof. The blocks 2 are provided with a central bore 5 in which is arranged one end of the connecting rods 6, said rods being secured to the bolts 3. The inner ends of the rods are connected to the outwardly projecting ears 7, said ears being integrally formed with the substantially rectangular plate 8 which is arranged within the movable block 9.

The block 9 may be constructed of wood or other similar material and provided with a plate 8 having the ears 7 thereon or this block may be formed of metal and having the ears 7 formed upon its longitudinal edges adjacent the inner end thereof. In constructing the block of wood, I provide the cross pins 10 which extend through the block to securely hold the plate 8 in position. The

outer end of the block 9 is provided with the suitable transverse opening 11 adapted to receive the bolt of a clevis or other device whereby the whifl'letree may be readily secured to a plow or any other implement or a vehicle.

Secured to the ends of the body 1 are the trace hooks 12, the ends of which are mounted for pivotal movement upon the ends of the bolts 3 so that the intermediate portions of the hooks may be disposed in any suitable position.

From the above, it will be apparent that I have provided a simple and durable whittletree whereby the strain or pulling power is equally distributed throughout the same. It will also be apparent that the body of the whiffletree may be constructed tubular in cross section and provided with a longitudinal groove, through which will project the plate 8, limiting the use of the block 9. It will be obvious that my improved whiffie tree is extremely simple in construction and can be manufactured at a comparatively low cost.

l/Vhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.

What I claim is 1. A whiffletree including an elongated body substantially rectangular in cross section, a block arranged in each end of said body, a transverse bolt extending through the block and the body, a movable block centrally arranged within the body, and means for connecting said block with the bolts.

2. A whiffletree including an elongated body, a block arranged in each end of the body, bolts extending through said blocks and the ends of the body, a movable element centrally arranged within the body, and contion, a block arranged in each end of said body, bolts passing through said blocks and the ends of the body, a plate arranged Within said body, ears formed upon said plate at the inner end thereof, and connecting rods having one of their ends connected to said 10 ears andtheir other ends connected with the bolts at the ends of the body.

In testimony whereof I hereunto affix my signature in the presence of tWo Witnesses.

HERMAN RASMUSSEN. Witnesses:

J. S. SMITH, D. O. HOBART.
