Show USEFUL RACK LIFTERS Automatic Unloader That Any One Can Easily Work. Illustrations and Description of Contrivance Con-trivance That Will Be Found Advantageous Ad-vantageous on Any Farm Racks Will Not Slip. I have an automatic unloader for heavy hay racks and other wagon bodies that any one can operate who knows how to drive a team, writes F. Haihaway of Fort Smith, Ark., in the Farmers Mail and Breeze. Fig. 1 shows one section of the frame as It appears before unloading while Fig. 2 shows the position of the frame with the rack on It. The posts A are 4 by 4's set firmly Into the ground. These posts should be set about 6 feet apart crosswise. The length and height of the frames depend on the racks used. BB are the lifting braces which must be well made and secure- Ci . i.vt.'i,if!a'f(J Fig S - : J How Lifter Does Its Work. ly bolted to the posts, yet not so tight as to hinder them from moving freely In loading or unloading a rack. The pieces C are2 by 6's bolted to the lifting lift-ing braces. At their forward ends two Bhort pieces of 2 by 4's (E) are bolted that strike against the rack as it is being driven between the frames, thus bringing up the lifting frames and raising the rack off the wagon. Two crosspiecfes of 2 by 4s (D) are bolted lengthwise to the posts to give the frames rigidity. Two blocks (F) are bolted at the forward ends of D to stop the forward movement of the lifting frame. These are placed a little lit-tle past the center so as to lock the frame while up. Two pawls notched at one end are bolted underneath the rack frame with the notched ends against the rear bolster of the wagon. This prevents the rack slipping back as It rises from the wagon. |
