UNITED STATES PATENT OFFICE.

CHARLES E. nacnn'r'r,

To all whom it may concern:

Be it known that I, CHARLES E. EACRE'I'I, a citizen of the United States, residing at Malvern, in the county of Mills and State of Iowa, have invented a'new and useful River Disk Plow, of which the following is a specification.

My invention relates to a river disk'plow and has for its object to provide a simple, inexpensive and durable means which will stir up the mud and sand in the bottom of a flowing stream, thus allowin the current to clean it out and make a well efined channel.

Other objects of the invention will appear in the course of the following specification. Referring to the accompanying drawings wherein like characters of reference denote similar parts throughout the several views: Figure 1, is a plan view of my river plow as constructed in accordance with my invention. Fig. 2, is a side elevation with one of the outer beams and lower connecting parts I broken away. Fig. 3, is a detail of one of 'the disks showing its connection with the beam.

' Referring to the drawings the reference character A, designates the stern of a suitable boat to which my apparatus is attached.

Connected at suitable points to the stern of the boat are a plurality of suitable brackets 1, to which are pivotally connected in suitable spaced relation the beams 2, which extend downwardly and rearwardly as clearly shown in Fig. 2. Connected to each of these beams 2 by means of suitable brackets, 3, is a rearwardly extending member 4, which, at its extremity is provided with a suitable bearing 5. The above parts will hereinafter be referred to as the disk carrying frame B. ,Working Within this bearing f5, and at right angles to the members 4, are the disk operating rods. 6, which are provided, with a suitable collar 7, engaging the top ofthe bearings 5, as clearly shown. These rods 6. are guided at their lower ends by means of the braces 8, and are threaded as at 9, and

connected to the threaded shanks 10, by means of the threaded coupling 11. Suitable bearings 12, are secured to the lower ends of the beams2, for guiding the shanks 10. Rotary disks 13, are carried by the lower ends of each of the shanks 10, which when' pulled through the mud and sand will stirzthe same up thus allowing the current to move it along making a well defined channel.

The upper ends of the disk operating rods Specifleationof Letters Patent. Application flledjpril 25, 1908. Serial'No. 429,208;

6, it will be observed, are provided with an arm 14. Connected to the outer ends of these arms 14, are the connecting rods 15, which are, at their opposite ends pivotally secured to the operating levers 16, which are each provided with a spring pressed locking device and which levers in turnare each pivoted to the notched sector 17, secured to the rearwardly extending members 4. It will be. observed by operating the levers 16, the disks 13, are turned at any angle desired for cutting into thesand and mud. It will be further observed that I prefer, though not necessarily, to locate the disk carrying frame B,'in pairs as clearly shown in Fig. 1, as by this arrangement they may be locked together by means of a U-shaped locking link 18, thus preventing the outer ends of the disk carrying frame B, from spreading due to the strain on the disk when cutting mud and sand.

It will be readily seen that each of the disk carrying frames is self adjustable owin" to the fact that each is pivoted indepen ent of the other to the pivot rod 1. By this arrangement should one of the disks fall into a hole or run over a high place orrock it will readily adjust itself.

For raising each of the disk carrying frames out of the water for repairing purposes and the like, I employ a drum 19 for each frame, each of which is mounted on a shaft 20, .which shafts in turn are each journaled in the bearings 21 and rovided with a ratchet 22 at one end. A 0g 23 is pivoted to each one of the bearings 21 adjacent said ratchets 22 and are adapted to engage the ratchets to keep each of the cables orthe like 24. which are wound around the drums 19 from unrolling. These cables 24 are always kept slack or loosened between the drums and the point of connection with the frames 25 and are sup orted intermediate their ends by means 0 the upwardly inclined arms 26, which have their up er ends each provided with a roller 27, ass own.

Patented Jan. 24, 19 11.

It will bereadily seen that when the apparatus is placed in a stream and the disk set at the proper angle they will cut an open furrow thus loosening and stirring up the'mud and sand which the current quickly .parts described I produce an apparatus wherein the operation thereof may be suc cessfully, conveniently and economically effected.

It is of course understood that vvarious changes in form, proportions and minor details of construction may be resorted to and that my apparatus may be placed at either the stern or bowof the boat or both Without departing from the principle or sacrificing any of the advantages of the invention.

What I claim is In a device of the class described, comprising in combination with a boat, a plus rality of spaced frame members pivotally connected to said boat, a shaft journaled at V eeame the outer end of said frames, a stub-shaft removably secured to the lower end of each of said shafts, a disk rotatably mounted at the lower end of each of said stub-shafts; means for changing the angle of said disks, 20
