PLOW.

Specification of Letters Patent.

Application filed March 5, 1912. Serial No. 681,770.

To all whom it may concern Be it known that I, OsoAR HOUGH, of the town of Camrose, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Plows, of which the following is a specification.

This invention relates to improvements in plows, particularly to those of the type used for brush breaking, and the objects of the invention are generally to simplify and improve the various parts of the plow to enable it to better perform the function required of it.

Further and more particular objects are to give increased support and strength to the beam and draw-bar, to provide an improved form of connecting means between the draw-bar and plow, to provide a share which will lie low and flat to the ground whereby any roots therein may be out before the ground is turned by the mold board. v

Further objects still are to provide an improved form of colter and improved connecting means between the colter share and landside.

Further objects of the invention will appear as the specification proceeds and for a complete understanding of the various parts thereof reference is made to the accompanying specification and drawings.

In the drawings, Figure 1 is a side view of a plow showing the improved plowing element mounted thereon. Fig. 2 is a side view of the plowing element detached from the plow and showing the side opposite to that shownin Fig. 1. Fig. 3 is a plan view of the under side of the plowing element. Fig. 4: is a plan view of the under side of the plow beam. Fig. 5 is a vertical sectional detail broken away taken through the front standard and the lower member of the beam. Fig. 6 is a perspective view of the share, the colter and land side element as seen when disassembled. Fig. 7 is a front view of the detached plow element, part being in section taken on the line 22, of Fig. 1.

In the drawings like characters of reference indicate corresponding parts in all the figures.

Referring to the drawings, A represents the plow beam of sufiicient substantial charactor to support the load and which is conveniently formed of suitable timber. It is given additional support on the upper side by means of a truss 10 including inclined elements 11 and 12 whose juncture is connected by a heavy bolt 13 with the beam A. The beam A is further braced by means of truss rods 14 extending longitudinally on the side thereof and passing through an eyelet 15 formed on the forward standard 13 which standard is adapted to assist in supporting the plowing element.

15 represents the mold board similar in general construction to that already known in the art but preferably modeled to a slighter slant in order not to kink the furrows. It is provided with an extension 27 which extends forwardly to meet the share F. This share which forms a characteristic and novel feature of the present invention is provided with an integral flange 28 conveniently formed by turning under a portion of the end of the share and swaging it out to a point when it may beeither hardened or a piece Welded on to the point to stand the Wear.

F represents the colter which also embodies novel features of the invention and which is provided at the lower extremities with a flange 29 which fits between the share F and the shoe 30. This shoe is preferably made substantially angle shaped in cross section and is adapted to fit over the front end of the landside 31, which front is tapered off for this purpose, the said landside being located between the said shoe and the flange 28 of the share F. It will be clearly seen that the share F and the integral flange 28 are adapted to embrace the flange 29 the shoe 30 and the landside 31. The colter is also characterized by having a much greater slant than usually employed, the slant being substantially 30 degrees. The share and mold-board are connected. by a frog 32 of usual construction. The mold-board is also supported by an angle brace 33 connecting the mold-board with a brace 34 which extends from the front standard to the landside. The extension 27 also provides a gradual slope to the mold-board.

To prevent the furrows from kinking or falling back again, an auxiliary tube mold Patented Mar. 23, 1 915.

board H is provided supported from the standard B and 18 and extending as farback as the ordinary mold-board and then extending a few feet back from the mold board. It

ported in position by means Which connects it With the front standard B.

The various landside, share, colter and frog are all connected together and suitably held in position by suitable fastening means such as bolts or rivets.

The plow is operated in the usual Way, the various elements having the functional advantages already pointed out and others which Will be apparent to those skilled in the art.

As many cl anges could be made in the above construction and many apparently Widely different embodiments of my invention, Within the scope of the claims, constructed Without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

Copies of this patent may be obtained for five cents each, by addressing the What I claim as my invention is:

1. In a plow and in combination a share having a flange formed integral With and bent beneath the point thereof, a tapered landside such landside being designed to be embraced at the point by the said share and its integral flange, as and for the purpose specified.

2. In a plow and in combination a share having a flange formed integral with ant bent beneath the point thereof, a tapered landside, a shoe adapted to fit over the front of the said tapered landside, said share and integral flange being adapted to embrace the shoe and the tapered landside substantially as described.

In Witness whereof I have hereunto set my hand in the presence of two Witnesses.

OSCAR l-IOUGH.
