HAY-RACK LADDER.

Specification of Letters Patent.

Patented Dec. 7, 1915.

Application filed February 3, 1914. Serial No. 816,211.

To all whom it may concern Be it known that I, VVILLIAM E. J ENTZ, J r., a citizen of the United States, residing at Platteville, in the county of Grant, State of Wisconsin, have invented certain new and useful Improvements in Hay-Rack Ladders; 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.

This invention relates to improvements in attachments for hay racks.

The principal object of the invention is to provide a simple and novelly constructed ladder for the hay rack which will be durable in construction and efiicient in operation.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of my improved hay rack ladder. Fig. 2 is a vertical section on the line :2-2 of Fig. 1. Fig. 3 is a vertical section on the line of Fig. 1. Fig. 4 is a horizontal sectional view on the line of Fig. 1. Fig. 5 is a fragmentary detail of the upper end of the ladders showing a modification thereof.

Referring particularly to the accompanying drawings, the frame portion of the lad der is formed of a single strip of channel iron doubled on itself as at 10 to form the depending side rails 11. The lower ends of these legs have a bolt 12 extending therethrough, this belt being disposed through transverse openings 13 in the sills 1st of the hay rack. The ladder is thus capable of being folded down into the rack when the rack is emptied. The strip of channel metal 1 is so bent that the channel portion presents its open portion inwardly, and extending between the legs or rails 11 are the rungs 15. These rungs are also formed of channel iron and have the attaching flanges 16 formed at their opposite ends and bolted or otherwise secured to the bottom walls of the opposite channels. Secured to one of the rails 11 near the upper end is a spring finger 17, this finger being arranged to clamp the driving reins against the rail. The curvedportion 10 has the bottom wall of the channel concave-convex as indicated at 18 in Fig. 2. This, in connection with the angular features of the members of the ladder serve to produce a rigid and durable structure. 1

Pivotally mounted on one of the side rail 11, near the lower end is a latch 19 which engages over the cross piece 20 of the hay rack, to hold the ladder in elevated position. The side rail is also provided with the outstanding pins 21 and 22 which limit the pivotal movement of the latch 19 in both directions.

As seen in Fig. 5 the upper end of the ladder is divided into the two curved portion 10, the inwardly directed ends 23 of which are detachably secured together by the bolt 24. Thus the ladder can be taken apart and conveniently packed for storage or shipment. It will be noted that the ends 23 curve away from each other thus provid ing a space therebetween for the reception of the end of the usual hay retaining pole.

What is claimed, is The combination with a hay rack including a rear transverse rail, of a ladder including side rails pivotally mounted on the rack, a pivoted beveled-nose hook mounted on one of the rails of the ladder and adapted for engagement with the transverse rail, and stop lugs on the said side rail for limiting the swinging movement of the hook where by the automatic engagement of the hook with the transverse rail is assured.

In testimony whereof, I affix my signature, in the presence of two witnesses.
