THOMAS D. AYLESVVOBTH, OF ILION, NEW YORK.

IMPROVEMENT IN HOP-FRAMES.

Specification forming part ot' Letters Patent No. 23,338, dated March 29, 1859.

To all whom it may concern.'

Be it known that I, THOMAS l). AYLEs WORTH, of Ilion, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Hop-Frames; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawing, making a part of this specification, and which represents in perspective one of the frames in question with the training cords or wires in place.

The object of my present invention is to obviate some of the defects that existed in my former plan of hop-frames.

In niy former invention the hooks that were to hold the trainingwires to the main wire would cast off, and there was a difficulty in letting down and raising up the inain wire. All these defects I have obviated in my present plan, and have guarded against all diftieulty in the use of these frames.

To enable others skilled in the art to make and use my invention, I will proceed to describe the saine with reference to the drawings A A represent two permanent posts or supports, at any suitable distance apart, and to one ot' which a Wire, B, may be permanently attached, and on the other there may be a drum or pulley, C, provided with a crank, D, and with stop-holes a and a pin, D, for the purpose of straining up or letting down said wire B at that end or holding` it at any desired height, said holes and pin acting as a dog and ratchet.

E is a stay or lniddle post, of which there may be any suitable number, between the outside ones. On these middle posts there are fixed supports F for the wire to rest in. The recess c, that the wire rests in on these middle posts, is wedge-shaped, or wide at top and narrowing toward the bottom. The object of this is to better hold the main wire B and prevent it from too freely slipping when said wire is let down to loosen the training-wires or gather the hops. It also prevents the outside posts from taking all the strain when the wind blows against the frame or vines, for when additional stress or strain comes against the main wire the tighter it is held in these supports.

d are the training cords or wires. They may be fastened at theirlower ends to stakes driven into the earth, and at their upper ends they are furnished with snap-hooks e, which, when placed over the lnain wire B, will not easily come oft, as their short part must be sprung open before they can be placed over or removed from the main wire.

Another advantage of the supports F, not mentioned above, is that if the wire B should happen to break it will not let down farther than to the tirst post next to the break, for the inoinent the weight or strain comes upon the wire itdraws so tightinto the w edge-shaped space as to hohl itself by the friction created.

The large drum or pulley C possesses many advantages over the pin heretofore used, i nasmuch as it does not so bend the wire as to destroy its liber and consequent strength.

Having thus fully described the nature and object of my invention, what I claim therein as new, and desire to secure by Letters Patent,

is- Y l. So hanging the main wire B upon the support-s F as that said supports will prevent the wire from slipping through them should it. accidentally' become loose or broken,substantially as herein described.

2. In combination with the main wire, suspended as herein represented, the uniting thereto of the training-wires l by springhooks, substantially as described and shown.

THOS. D. AYLESWORTH.
