TO ALL WHOM IT MAY CONCERN:

Be it known that I, URIAH HUMMER, of White Oak, in tho county of Lancaster, and State of Pennsylvania, have invented a new and useful Improvement on a Manure-Drag; and I hereby declare that the following is a full* and exact description of the construction and operation of the same, reference being had to the accompauying drawings, making a part of this specification, in which-- A i Figure 1 is a'perspective View of the entire machine, showing my improvements in place.

FignrcZ is a side view, set for deep dragging.

Figure 3 the same set for shallow dragging.

Figure 4 the same when the hook is turned for disehargng thelload.

Figure 5 shows the forwardhook-holdor and spring and operating-rod.

The nature of my invention consists in providing a means to adjust the hook to a shallow bed of manure, and so as to clear the door-sili of the stable, when the tines are not filled so as to cover them, as is the case where a deep bed is to be removed, for which purpose it is equally well adapted.

To enable others skilled in the art to make and use my invention, a glance at fig. 1 will enable any one to comprehend the general features, which in some respects are much like others, such asPatent No. 64,861, of May 21, 1857; but diifers substantially in the combination and arrangement of the parts.

The side beams A A, cross-pieces B C, and handles H, with the hook D, and leverarm G, although -difi'ering in the general construction, are yetessentially the same. The novelty of my invention consists in providing the handle with a cross-piece, J, lodgcd in a hook at one end, and held by apivot on the other, on the uprights K that support the handle. The upper cross-piece I of the handles is held and slides on the one side in a link, R, the other end being connected by a pivot also. To the cross-piece R there is a rod, 0, that connects with one end of a lover, P, (fig. 5.) This lever hasa central pin or pivot upon which it turns. The other end of this lever P is connected to a holder, T, with a notch. There is also a spring, S, resting against the notched post, which is held also by a pivot in a slot in the sunken crosspiece W. There is a bent iron strap, N, on the side to prevent the lever Pto strike the jamb of the door if made to project. The four-pronged revolving drag-head D has two curved runners-E, connected with an extra cross-brace, E. The central drag-arm G is provided at its end with a clasp or hook, which presses against the under side'of the cross-bar,I. When the machine is deep for a dense bed of manure, to relieve the handles from the upward pressure, iron braces Zi are afliixed from the rear cross-piece to the handles. When there is but a shallow bed of manure, no provision has heretofore been made to clear the sill of the door, as in that'case a shallow load will lexpose the tines, which catch against the sill, and cause a strain or break in some of its parts. To remedy this, I unhook the cross-piece J, and the droga-arm is allowed to enter a notch cut out of the inner side of the hind cross-piece, and the upper end I in the link is drawn back, slid over the drag-arm G, to the position shown in fig. 3, compared with the position, fig. 2, and sill shown, set their relative depth.v To dislodge the load, it is only necessary to release the drag-arm, when it flies round andlodges under the round spring-latch head T, where it is held as in fig. 4, throwing the tines up, and bringing the two run-ners F on the ground. I

Aware of the numerous manure-d'ags pate utod, it occurred to me to improve upon them, and having onc .made as herein presented, my neighbors were as much pleased Vwith its efficiency in other respects, and the advantage of shifting the hook,'as myself, so that I also desire to secure what I believe to be new in the arrangenen t of the several parts, without claiming any of the combinations used by several of my neighbors, for which they obtained a patent. My mode of hitching the horse difers also, by the means I employ in fixing the chains in front and under the side beams, and side irons L, aflixcd behind to the bearings of the drag-head, giving the forward portion of my machine a draught upwards, greatly relieving the horse.

What I claim as my invention, `and desire to secure by Letters Patent, is-

The arrangement of my drag-arm G with its hook g, in combination with the two cross-pieces J I, hook and link j It, and connecting-rod O, with the lover P, notched pawl T, and spring S, substantially in the manner and for the purpose specified.
