A. MoKEE. DRAFT BQUALIZER.

No. 495,994. Patented Apr. 25, 1893.

ALEXANDER MOKEE, OF STUART, IOWVA.

DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 495,994, dated April 25, 1893.

Application filed November 18, 1892. Serial No. 452,466. (No model-) To all whom it may concern.-

' Be it known that I, ALEXANDER MOKEE, a citizen of the United States of America, residing at Stuart, in the county of Guthrie and State of Iowa, have invented an Improved Draft-Equalizer, of which the following is a specification.

My invention consists primarily in mounting a large and small pulley which are connected with each other, in a suitable bracket upon a wagon tongue on the side thereof in which the shorter arm of the evener is extended and in the rear of the same and in winding a cable partially around the smaller pulley and attaching it to the larger arm of the evener and winding a like cable partially around the larger pulley in an opposite direction and then attachingit to the shorter arm of the evener as and for the purposes hereinafter more fully set forth and pointed out in my claims.

In the accompanying drawings Figure 1 is a plan view of the complete equalizer with parts of one of the pulley wheels broken away to show the point of attachment of the cable. Fig. 2 is an enlarged detail perspective view of the bracket and pulley wheels. Fig. 3 is a perspective view of the socket whereby the larger evener arm is pivotally attached to the tongue.

Referring to the accompanying drawings the reference letter A is used to designate the tongue. v v

A is a longer evener arm which is pivotally attached to the tongue by means of the socket A A designates the shorter evener arm which has a pivotal connection with the socket A at the point A B designates abracket secured to the tongue Ain the rear of the evener, arms, and extended laterally therefrom in the direction of the shorter evener arm.

B and B are two pulleys of diiferent sizes fixed together and mounted in the outer end of the bracket B. The cable 0 is passed around the smaller pulley and then attached to the rod (3 which in turn is detachably and adj ustably connected with the evener arm in the bores (J The remaining cable D is passed around the larger pulley and attached to the rod D which has a like connection with the shorter evener arm. It will be obvious that the relative amounts of power desired to be applied to either side of the tongue may be regulated by changing the size of the pulley wheels. By this arrangement, namely a large and small pulley connected with the tongue in the rear of the evener arms, it will be seen that a comparatively small amount of power applied to the shorter evener arm will approximately counterbalance a greater amount of power applied to the longer evener arm, but if the pulleys were located directly above the tongue a strong side draft would be produced. To overcome this objectionI have provided the bracket B to be extended laterally from the side of the tongue in the direction of the shorter evener arm and in view of the fact that a great portion of the power applied to the longer evener arm is transmitted diagonally to the opposite ends of the tongue to the pulleys B and all of the power applied to the shorter evener arm is applied to the same side of the tongue, this side draft is thereby eliminated.

Having thus clearly described the device, whatI claim as myinvention, and desire to secure by Letters Patent of the United States therefor, is

1. An improved draft equalizer comprising the following elements in combination, to wit; a suitable tongue, a comparatively long evener arm pivotally connected therewith, a shorter evener arm pivotally connected with a suitable support and extended in an opposite direction from the tongue, a suitable bracket fixed to the tongue in the rear of the evener arms, and extended laterally therefrom in the direction of the shorter evener arm, two pulleys of unequal sizes fixed together and mounted in said bracket so as to be at the side of the tongue for the purposes stated, acable attached to the longer evener arm and passed partially around the smaller pulley and fixed thereto, a second cable attached to the shorter evener arm passed partially around the larger pulley and fixed thereto, for the purposes stated.

2. An improved draft equalizer comprising the longer evener arm and passed around the smaller pulley and fixed thereto,'a like cable fixed to the shorter evener arm passed around the larger pulley and fixed thereto substan- I 5 tially in the manner set forth for the purposes stated.

ALEXANDER McKEE.
