UNITED STATES PATENT OFFICE,

IIIRAM BARBER, OF CHICAGO, ILLINOIS.

WHIFFLETREE SPECIFICATION forming part of Letters Patent No. 558,024, dated April 14, 1896. Application filed November 20, 1894. Serial No. 529,349. (No model.)

To all whom it may concern.-

Be it known that I, I'IIRAM BARBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Whiffletrees; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Of the drawings herewith submitted, Figure 1 is a perspective view of my-improved whiftletree. Fig. 2 is an inverted view of the central portion of my improved whiffletree with the lower face or wall thereof removed. Fig. 3 is a sectional view of my improved whiflietree on the dotted line 3 3 of Fig 1. Fig. 4 is aview in perspective of the anchor-plate used in my improved whiffletree. Fig. 5 is a view in perspective of the plate which forms the lower face of the central chamber in in improved whifiletree.

It will be observed that in the construction of my improved whiflletree I make use of the arms a Ct, with their interior ends attached to the side walls 0 c of the central chamber C, with the central longitudinal line of the arms a a at right angles to the central longitudinal line of the chamber 0, while the upper surface of the arms a a, on the horizontal line thereof is uniform with the upper surface of the upper face or wall of the chamber C,which is provided with the central longitudinal slot- O. The inner ends of the arms Ct a are also provided with the brackets b I) b b. I also make use of the plate M, provided with the central longitudinal slot 0, and the lugs Z Z Z Z, also the anchor-plate P, provided with the hoods d d and the aperture q. The hoods are formed by the rear walls 10 w, the interior surface of the plate P, and the side wallsuu and 'u o. I also make use of the rods R R and the coil-springs S S.

The object of my improved whiflletree is to secure a yielding connection between the draft-animal and the loaded wagon or other vehicle. The value of such a connection is now widely recognized. Various devices have been used heretofore to accomplish this purpose. In one a leaf-spring attached longitu-' dinally at the rear of a common wooden whiffietree has been found highly satisfactory. In others the whifiletree has been inclosed in an iron casing with a coil-spring in front and upon which it is pressed when it is moved forward. In still another form the whiflietree is attached to the axletree of the wagon or other vehicle by means of chains provided with coil-springs, which afford the necessary elasticity when forward pressure is applied to the whiffietree. In all these devices, however, there is lacking somewhat of simplicity in construction and somewhat of stability or durability when in actual use Simplicity of construction is of great importance, since it has relation to the convenience found in using the device and also to the cost thereof,while the general use of any article is practically impossible unless it has durability.

In my improved whiffletree I have sought to combine, in the highest degree practicable, I simplicity of construction and durability.

To this end my improved whiffletree, in its preferable form, is made either of cast-steel or the highest grade of refined malleable iron. 7 5

The arms of my improved whiflietree are in the form of a hollow oblong cube about twenty-three (23) inches in length, two (2) inches in width by one and three-fourths (1%) inches in thickness. The central portion of my improved whifiletree is in the form of a hollow oblong cube or chamber about eight and onehalf (8%) inches in length, four (4) inches in width by two (2) inches in depth.

The arms of my improved whifiletree are attached to the sides of the central chamber thereof slightly forward of the center thereof in cross-section.

The upper surface of the arms of my improved whiffletree are made integral with the 0 upper surface of the central chamber thereof, while the sides of the arms are also made integral with the sides of the central chamber of my improved whifrletree at the point of junction. 7

In each of the four angles formed by the junction of the arms of my improved whifiietree with the sides of the central chamber thereof there is a bracket, made integralat the interior end and side with the arm and side of the central chamber, respectively, of my improved whiffletree. This bracket is designed to furnish a point attachment for the plate which forms the under side or face of the central chamber of my improved whifiletree.

The upper surface of the central chamber of my improved whifiietree is provided with a central longitudinal slot about four inches in length and extending backward from a point about on the forward line of the arms of my improved whifiietree. The plate which forms the side or face of the central, chamber is also provided with a corresponding slot. When in position, this plate is bolted firmly to the brackets attached to the exterior side walls of the arms and central chamber of my improved whiffietree.

The central chamber in my improved whiffletree is designedfor the reception of two coil-springs, two rods passing through same longitudinally, and anchorplate. The anchor-plate at the front end thereof is provided with two hoods for the reception of the forward ends of the two coil-springs, respectively, while the rear end thereof is provided with an aperture for the passage of the whiffietree-bolt.

The end walls of the oblong chamber in my improved whiffietree are provided with suitable apertures for the passage of the body of the rods which are inclosed by the coil-springs. The rear walls of the hoods of the anchorplates are also provided with corresponding apertures for the passage of the stem of the rods.

When, therefore, the several parts of my improved whiffietree are in position, the coilsprings S S are placed longitudinally in the oblong chamber C, with front ends thereof resting in the hoods d d and the rods R R passing through the same and also through the walls 0 c of the chamber 0 and the end walls w w of the hoods cl d, while the plate M is firmly attached to the arms a a and chamber 0 by means of the brackets b b b b and the lugs ZZZZ. When attached to the wagon or vehicle, the bolt B passing down through the forward end of the slot 0, the aperture q in the anchor-plate P, through the forward end of the slot 0, and thence down through the pole, my improved whiffletree is held firmly in position, and when forward motion is given to the arms a a and central chamber C the rear wall 0 thereof is driven against the rear ends of the coil-springs S S, the forward ends of which are held in the hoods d cl. By this process the coil-springs S S are compressed, and thus the yielding connection secured between the vehicle and the draft-animal.

Having thus fully explained the object and purpose of my improvedwhifiletree,its method of construction and mode of operation, what I claim as novel and as of my invention, and for which I claim Letters Patent, is as follows:
