HAY-RACK LIFT.

To all ZIP/BOWL it may concern:

Be it known that I, Josnrn ANToN JOHN- son', a citizen of the United States of America, residing at Blue Earth, in the county of Faribault and State of Minnesota, have invented new and useful Improvements in Hay-Rack Lifts, of which the following is a specification.

The object of the invention is to provide a simple and convenient method whereby a hay rack may be removable from and replaced upon a wagon running gear without involving the physical effort ordinarily incident to this procedure and to facilitate the attachment to the rack of the lifting means whereby the load may be transferred to the place of storage; and with this object in view, the invention consists of the construc tion and combination of parts, apreferred embodiment of which is shown in the drawings wherein z- Figure l, is a side view of the apparatus showing the adjusted arrangement of the counterbalance weights for maintaining the rails in an inclined position as when driving a wagon between the same.

Figure 2 is a similar view showing an adj ustment of the rails permitting of the backing of the wagon into its position between the rails preliminary to a subsequent for ward movement to displace the rack from the running gear.

The apparatus consists essentially of laterally spaced. posts or uprights 10, upon which are mounted at intermediate points, the tilting rails 11 provided at their extremities with. pivotal pendent supports Or leg, 12 adapted to be folded by swinging movement in planes parallel with the rails to permit of the depression of either end of a rail while adapting the near rails to swing to a vertical or upright position to support the rails in a substantially horizontal position for the reception of a rack 13 which may be of the ordinary construction and is usually supported for removal upon the bolsters 14 of a farm wagon running gear such as that indicated at 15.

The raclr receiving rails are provided adjacent to one end with stop blocks 16 forming shoulders for engagement with the ends of the wagon rack to limit the longitudinal movement of the rack relative to the rails, as a wagon is driven between the rails, so as to permit the running gear of the wagon to be drawn from beneath the rack, and thus Specification of Letters Patent.

leave the latter in a supported position upon the intermediately pivoted rails of the lift. Also each. of said rails is preferably provided with an. adjustable counter weight 17 movable to occupy a position at either side of the plane of the pivoted points or axes of the rails, so that when, as shown in Figure 2, it is desired to arrange the rails in a tilted position to permit of driving wagon forwardly between the rails. the counter weights may be adjusted to positions at the opposite sides of the uprights or posts from the shouldered extremities of the rails, so that as the wagon progresses the rails by the contact of the rack therewith will be moved to a horizontal position in which they will be held by the swinging of the previously folded uprights or legs to their normal positions as the rack end comes in contact with the stop blocks and the continued forward movement of the wagon running gear serves to shift the rack from the running gear to the supporting rails. The upper edges of the rails are preferably located at a slightly greater distance from the surface of the ground than the height of the rack as supported by the running gear of the vehicle, so that the weight of the rack with its load will by reason of the movement of the rack to its normal or horizontal position serve to raise the rack and reduce the friction thereof upon the running gear.

hen it is preferred for any reason to reverse operation of shifting the load from the running gear to the lift, the forward uprights or legs may be folded, to permit of the depression of those ends of the rails adj acent to the stop blocks as indicated in Figure 2, whereupon the wagon with the rack supported thereby may be backed between the rails sufliciently to depress the rails to their normal or horizontal positions,-the forward end of the rack then being in the rear of the stop blocks-as succeeding forward movement of the team with the running gear of the vehicle will involve the engagement of the rack with said blocks and the consequent shifting of the rack and its load from the running gear to the rails of the lift.

Obviously the reverse of this operation in applying a rack to the running gear from a position on the lift may be accomplished with. equal facility, inasmuch as it is only necessary after having moved the wagon to the proper position under the rack and fasten the rails t knock out the terminal uprights or legs to permit of the engagement of the rack with the "forward holster of the running gear.
