IMPROVEMENT IN MOLE-FLOWS.

Specification forming part of Letters Patent No. 25,334, dated September 6, 1859.

To all whom it may concern:

Be it known that I, IRIS Henson, of Stouts Grove, in the county of McLean and State ot Illinois, have invented a new and useful Improvement in Ditching-Flows; and I do hereby declare that the following is a full, clear,

and exact description of the same, reference. being had to the accompanying drawings,

forming a part of this specification, in which Figure 1 is a perspective view of my improvement in ditching-machines. Fig. 2 is a plan or top view of the same. 'Fig. 3 is an under view of the mole.

Similar letters of reference in each of the several figures indicate corresponding parts.

The nature of my invention consists in the combination of a beam which has a horizontal joint forward of the colter, with a rod arranged over the top of said joint, and with a horizontal adjusting and stop plate, whereby that port-ion of the beam of the plow forward of the colter can be adjusted so as to overhang dry land without changing the position of the latter, while the portion which carries the cutter lies in line with the middle of the slough or ditch. Thus having the beam adjustable admits of the capstan or power employed to operate the machine being arranged on dry land instead of in the slough or ditch. This is very important, as must be evident.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents the beam, made in two parts, a b, which are united by a horizontaljoint, B, at a point slightly forward of the colter O.

D is the mole attached to the bottom of the colter. This is made in two parts, 0 d, and united by horizontal V-shaped joint 0, and loosely-fitted connections f g, as shown, so that the rearportion may turn independently of the front portion in making short turns, and thus avoid breaking or bending the colter.

E is the roller which gages the depth at which the mole is to cut.

F G are the horizontally and vertically arranged bow-shaped brackets which suspend the roller.

H is the set-screw by which the beam and roller are brought nearer together or moved farther apart vertically, so as to gage the depth of out. The set-screw screws into a female socket formed in the rear of the beam, and therefore, as the bracket G is capable of turning at h, while the bracket F cannot change its location on the screw, the beam is caused to descend or rise, and thus lower or elevate the mole when the screw is turned in the proper directions.

I is the rod, which is arranged on top of the beam so as to cross the horizontal joint B. The rear end of this rod is fastened permanently to the rear portion of the beam. The iront end is left loose.

J is a plate arranged transversely on the front part of the beam, fitting in a dovetail or slot, so as to be tlnsh with the top of the beam. This'plate is furnished with a seriesof adjusting pin-holes,i i, on each side of the beam, and with two removable stop-pins,j 9','(m its upper side. With this plate and the rod I the two parts of the beam can be kept in a straight line, as shown in black in Fig. I.

To adjust the front portion of the beam, as shown in red, the stop-pins are withdrawn and the beam moved laterally on its joint. The stop-pins are now inserted in holes on either side of the rod I, they being turned so as to suit the relative position or the rod, plate, and beam. \Vhen the beam is thus adjusted the colter and mole will run in the center of the slough or ditch, while the nindlass or power by which the plow is moved will be on dry land.

What I claim as my invention, and desire to secure by Letters Patent, is-- The combination of a ditching-plow l)! am having a horizontal joint forward of the more and colter, with a. rod arranged over the top of said joint, and with a horizontal adjusting and stop plate, substantially as set forth.

IRIS HOBSON.
