ADULPHE CORDEAU, OF STE. MADELEENEI, QUEBEC, CANADA, ASSIGNR 0F ONEHALF T0 JOSEPH IVI. AUEHER, Ul? ST. HILAIRE, QUEBEC, CANADA.

DTCHINGr-FLQW.

Application filed February l1, 1914.

T0 all whom t may concern:

Be it known that I, ADOLPHE CORDEAU, a subject of the King of Great Britain, residing at Ste. Madeleine, Province of Quebec, Canada, have invented certain new and useful Improvements in Ditching- Plows; and ll do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to ditching plows.

ln order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

ln the drawings: Figure 1 is a top plan view of the plow and Fig. 2 is a side view.

The main objects of the invention are to produce a ditching plow of strong and simple construction which can be effectively used for cutting the ditch and removing the earth at the same time, and which can be manufactured in large numbers at small cost.

Referring to the drawings in detail, l designates the plow share which is cast as a flat plate having its forward portion pointed as at 2 and beveled as at 3 to form cutting edges. Share 1 is secured to standard 4 by counter sunk screw bolts 5. rl`he upper' portion of standard 4 is reduced to form a neck 6 which is inserted through the enlarged portion 7 of beam 8 and secured therein by a binding screw 9 or other suitable means. rll`he shoulders on each side of the neck 6 engage the under face of the beam and thus brace the standard securely in position. Standard 4 has its front edges beveled to form a cutting edge 10.

An inclined cutting plate 11 is secured to the front portion of share 1 in the center thereof with its point continuous with the point of the share and its inner end contiguous to the cutting edge of the standard. lBy this means, a continuous cutting edge is provided from the point to the cutting edge of the standard. Above and in advance of the point 2 a colter knife 13 is secured through the enlarged portion 14 of beam 8.

Specification of Letters Patent.

rateatea ret. re, rais.

Serial No. 818,140.

A clevis 15 is provided at the forward end of the beam Yfor traction purposes.

Forwardly and downwardly slanting plates 17 are secured to the back portion of the share 1, one on each side of standard 4. The rearward ends of plates 17 are cut on a slant to fit the forward portions of mold boards 19 which are pivoted at their inner ends to the back of standard 4. lThe mold boards are braced at their proximate centers by lateral braces 21 pivoted thereto at their lower ends and having their upper ends slidably connected to handles 22 of any well known form, and by a horizontal brace rod 20.

The lower edges of the mold boards are slightly flared, as at 23 to form a lateral groove or channel, for a purpose to be presently described.

ln order to regulate the depth of the ditch a gage runner 16 is provided, in front of colter knife 13, which limits the depth to which the plow can sink.

llt has been found that in plows having rigidly secured mold boards, the boards often break because of sudden strains put upon them due to hard ground or ground in which there are many stones, which causes uneven travel or jumping of the plow. To overcome this difiiculty the inventor has the mold boards pivotally connected to the standard and has provided-a tension spring 24 which is connected at its lower end to the back of the share and has its upper end secured to a bolt 25 passed through brace rod 20. Bolt 25 is threaded through a hand nut 26 so that by turning the nut the tension of spring 24 may be varied as desired.

By this construction, in combination with the slidable mounting of braces 21, the mold boards are permitted to give suiiiciently to prevent injury from any sudden shocks, while at the same time maintaining their operative position.

IThe operation is as follows: As the plow is drawn forward the colter knife 13 makes an entering cut for the share and standard. Owing to the continuous cutting edge eX- tending from the point to the front edge of the standard, as previously described, the out of the plow is one smooth continuous cut, thus eliminating the jarring or jerking often encountered in the ordinary type of plow. As the earth is cut, it flows over the upper face of share l, is divided by cutter 11 and standard 4, and flows on to the plates 17. Plates 17 act to elevate the earth and direct it against mold boards 19. The earth falls into the channels formed by the flared portions 23 of the mold boards and, as the plow is drawn forward, is forced along the channels and deposited at each side of the ditch.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination, a beam, handles secured thereto, a standard detachably secured in the beam, a share carried thereby, downwardly and forwardly slanting lateral plates secured thereto, a cutting plate connecting the point and the standard midway of its vertical length, and means for conveying the earth from the slanting plates and depositing it to each side thereof.

2. In combination, a beam, traction attaching means therefor, handles secured thereto, a standard detachably secured through the beam and having its front edges beveled to form a cutting edge, a share secured to the lower end thereof, a cutting plate secured to the upper front portion of the share so as to form a continuous cutting edge from the point to the front edge of the standard, forwardly and downwardly presented lateral plates secured to the share at each side of the standard, mold boards pivotally secured to the back portion of the standard, and means for permitting movement thereof.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

ADOLPI-IE CORDEAU.
