To ctZZ whom it may concern.-

Be it known that we. JAMES HOWARD, of Bedford, in the county of Bedford, and HENRY WILLIAM GIBBs, also of Bedford, aforesaid, England, agricultural engineers, have invented certain new and useful Improvements in Flows, of which the following is aspecilication.

This invention relates to that class of plows (whether single, double, or multi-furrow) which has a detachable fore carriage with two wheels on one aXle-tree, or a pair of axles attached to an axle-bed.

The object of the invention is to facilitate the operations of plowing.

In plows with detachable fore carriages in which the beam of the plow is supported on the fore carriage the angle which the wheels and axle form with the ground-line varies according to the depth at which the plow is set to work; but it is important that the vertical position of the landside of the plow should be maintained at all depths, and to accomplish this various devices have been employed. To attain this result in a more simple and cffi cient manner than heretoforgwe adopt the arrangements of plows shown in the accompanying drawings.

Figure 1, Sheet I, is a side elevation of an arrangement of plow and fore carriage in general use in eastern Europe with our improvements applied thereto, and Fig. 2 is a plan view of the same.

In Sheet II, Fig. 3 is a front View of the fore carriage complete, and Figs. 4 and 5 represent the fore carriage in positions varying from that of Fig. 3.

A is the plow-beam, to which is bolted the plow body or standard B, and fitted, as usual, to the plow-body are the sole-plate b, the share b, and the breast b.

O is the colter, attached to the beam in the usual manner. The beam is made of rolled iron or steeLby preference of Isection, (see Fig. 1*,) and to its rear end is bolted the haudle A, of wrought-iron, which is continued down to the plow-body and made fast to it and to the sole-plate.

D is the fore carriage, carried by a pair of wheels which run freely on a fixed axle-tree,

d. This axle tree (Figs. 3, 4., and 5,) is bent to an arched or segmental shape, for the purpose to be presently described. Mounted adjustably on this axle-tree isa sliding block or bracket-piece, d, for supporting the forward end of the plow-beam. The radius of the are we so calculate that theaxletree d shall,while the plow is at work, maintain the horizontal position of the sliding block or bracket-piece d, whatever its set position upon the axle-tree may be, for adapting the plow to work at dif- 6o ferent depths. By this means we are enabled to maintain the vertical position of the landside of the plow.

In order to maintain a uniform width of furrow after the adjustment of the sliding block 6 or bracket-piece d, we fit the block with an adjusta-ble gage-plate, (i formed with lugs at its opposite ends, between which the forward end of the beam lies. This gage-plate serves to maintain the set distance between the beam 76 and the furrow-wheel, and thereby to prevent any variation in the Width of the furrows.

To the axle-tree is connected the usual draft-bar, I), with adjustable lever for setting the draft-hook to the right or left, and to the draft-bar is connected the chain c, which passes below the axle-tree and thence to the beam A, to which it is attached. The draft of the cattle causes the under side of the fore part of the beam (which is made with a broad flat surface) 80 to bear upon the sliding block or bracketpiece of the fore carriage. Thus while the draft-cattle are moving forward a connection, more or less rigid, is maintained between the beam and fore carriage, but 011 the slacken- 5 ing of the draft at the end of the furrow the rigid connection ceases, when the turning of the plow-beam upon the fore carriage as well as the turning of the plow for a fresh furrow is rendered easy. 9

The adjustable sliding block or bracketpiece (2 is shown in side and end views at Fig.

6 and the gage-plate d in face view at Fig. 7. The bracket-piece is made by preference of angle-iron, slotted or pierced with holes to receive a pair of screwed staples, d, which are intended'to grip the axle-tree and hold the I tree is tipped in the opposite direction, the 0 bracket-piece in its set position. The screwed ends of these staples pass through holes made in the gage-plate d, and, by means of nuts screwed on them, the gage-plate is held firmly to the adjusted bracket-piece. This gage-plate is pierced with a row of holes for the reception of the screwed ends of the staples, and provision is thus made for its being adjusted endwise or laterally of the carriage.

To allow of the beam rolling upon the bracketpiece when the plow is to be thrown out of action, the lugs of the gage-plate are made at such a distance apart as will provide for a slight lateral play of the forward end of the beam.

Referring now to Fig. 3, it will be seen that the bracket-piece is set in a central position, the depth of plowing required being such as may be effected without tipping the axle-tree or fore carriage, the depth being due solely to the difference of diameter between the furrowwheel and the land-wheel.

Fig. 4shows the bracketpiece set for the production of a shallower furrow. Thus the bracket-piece is shifted nearer to the furrowwheel, and the fore carriage is tipped and inclined toward the nnplowed land.

At Fig. 5 the fore carriage with its axlebracketpiece being shifted from the furrowwheel side to the land-wheel side of the carriage. Thus in all three examples of position the adjustable bracket-piece will retain its horizontality, and consequently the vertical position of the landside of the plow will be maintained Whatever depth of furrow is being plowed.

Having described the nature of our said invention, and in what manner the same is to be performed, we claim In a plow constructed with a fore carriage, the means described for maintaining the verticality of the plow-body irrespective of the depth of the furrow being plowed. such means consisting of an arched axle-tree or its equivalent and an adjustable sliding block or bracket fitted thereto, with gage-plate on which the forward end of the plow-bean bears, substantially as herein described.
