Serial No. 612,249.

To all whom it may concern:

Be it known that I, JAMES R. Rossn'rren, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Plows, of.

which the following is a specification.

One object of this invention is to construct the parts of a plow in such manner that they may be used interchangeably and thereby reduce the number of parts or extras the dealer must carry in order to meet the olemands of the plow users. The interchangeability of the parts also reduces the number of patterns the manufacturer must employ and consequently lessens the cost of procluction.

There is a well-defined and growing demand for a plow with interchangeable shares and my present invention seeks to meet that demand by providing a plow which will prove eflicient whether the cutter is integral with or separate from the share and whether the share is or is not formed with a gunnel, the several parts in every instance being secured together in such manner as to preserve the shape of the plow and reduce the liability of breakage.

A further object of the invention is to provide a moldboard in which the liability of a destroying fracture is reduced to a minimum.

Another object of the invention is to so secure the end of the beam to the saddle or standard as to overcome the tendency of the same to work loose under the strain to which it is subjected.

Other incidental objects of the invention will appear as the description of the same proceeds and at the end of the description the novel features of the invention will be distinctly pointed out in the claims.

One form of my invention is illustrated in the accompanying drawings, in which Figure 1 is a side view showing the parts assembled, the share having a gunnel and the cutter being removable. Fig. 2 is a similar view showing a share having the cutter integral therewith but formed without a gunnel. Fig. 3 is a plan View of the standard with the beam in section. Fig. 4 is a horizontal section on the line 4- of Fig. 2. Fig. 5 is a perspective view of the standard or saddle. Fig. 6 is a side view of the standard. Fig. 7 is an elevation of the standard partly broken away looking at the side opposite that seen in Fig. 6 and indicating the end of the beam in dotted lines. Fig. 8 is a detail view of the end of the beam. Figs. 9 and 10 are elevations of the landside looking at the opposite sides of the same. Figs. 11 and 12 are detail perspective views of the false gunnel. Fig. 13 is a detail rear elevation of the moldboard.

The standard, frog or saddle 1 is provided on its moldboard side, or face, at its upper end, with a recess or seat 2 to receive a rearwardly projecting lip or lug at the upper end of the cutter as is usual to retain the cutter in position. On the landside face or member of the standard or saddle is a horizontal rib 3 which curves downwardly at its front end and terminates in a shoulder 4. The under surface of this rib is bcveled'or arranged at an angle to the landside face of the saddleand its rear end 5 is inclined rearwardly from its lower to its upper edge and is also beveled inwardly and forwardly. Below the rib a recess or groove 6 is formed in the landside face of the saddle, said groove being of an oval or pear shape with its smaller or tapered end adjacent the extreme front end or point of the saddle. The walls of the groove merge into the face of the saddle and the groove extends rearwardly and slightly upwardly from the front extremity of the saddle to a point about midway the landside face thereof, the depth of the groove gradually increasing toward its rear wider end. Below the rear end of the groove on the lower edge of the saddle is a lateral lug 8 having its front and rear ends slightly converging outwardly and also upwardly while the lower edge of the saddle is cut away so that the portions in front and rear of the lug occupy slightly different horizontal planes, an approximately vertical shoulder 9 being thereby provided on the lower edge of the saddle. The gunnel 10 and the landside 11 meet over this lug 8 and are so shaped that when they engage they will be interlocked between the lug and the rib 3 in such a manner as to effectually preserve the curve of the plow.

The lower corner of the gunnel is cut away so as to fit against the front end and over the upper side of the lug as shown, the edge of the gunnel being beveled to correspond to the inclination of the front end of the lug. The rear end of the gunnel extends beyond the front end of the rib 3 and its cutter will rest against the front edge of the saddle, whether formed integral with the share and gunnel or separate therefrom, and if a detachable cutter be employed it will be provided with a lip adapted to engage recesses in the share and the moldboard to hold its lower end in position. In molding shares with gunnels a swell is very apt to form on the gunnel, and, heretofore, this swell has destroyed the curve of the plow and frequently prevented the use of the gunnel. By providing the recess 6, however, I am enabled to use all these gunnels as the swell will be accommodated in the recess and the gunnel may then be fitted close to the landside face of the standard or saddle so that the outer faces of the share, gunnel and landside will be flush and follow the desired line.

The landside 11 has its front lower corner cut away, as shown at 18, to fit against the rear end and over the upper side of the lug 8, the rear wall of said cut away portion being beveled inwardly and rearwardly to correspond to the inclination of the rear end of the lug. Rising from the said cutaway portion or corner, the front edge of the landside presents a vertical beveled shoulder 14 adapted to engage the intermediate portion of the rear edge of the gunnel. An inclined shoulder 15 being provided at the upper end of said vertical shoulder to engage the rear portion of the upper inclined edge of the gunnel. The shoulder 15 extends to the rib 3 and the upper edge 16 of the landside curves upwardly and rearwardly so as to follow the out-line of the lower side of the rib, being beveled to fit closely against the same. The gunnel is thus held by both the saddle and the landside so that any tendency of the gunnel to swing upwardly is positively resisted and effectually overcome while at the same time the end of the landside is held against vertical movement and has an extended engagement with the saddle to aid in resisting the thrust thereon.

About midway its length, the upper edge of the landside is projected upwardly and beveled inwardly and forwardly to provide the offset or shoulder 17 adapted to engage the shoulder 5 on the rear edge of the saddle at the end of the rib 3. On its inner face, along its lower edge, the landside is constructed with a rib or flange 18 which terminates flush with the rear wall of the cutaway portion 13 so as to engage the shoulder 9 of the saddle. This flange expands laterally toward its rear end and constitutes a wide runner for the landside while the square engagement of its front end and the landside with the shoulder 9 and lug 8 on the saddle creates a wide bearing between the landside and the saddle to aid in holding the share to its work and resisting the strain ofopening the earth.

The arrangement and beveled construction of the several shoulders presented by the saddle, the lug 8, the gunnel, and the landside brings the several parts into such assembled relation as to preserve the curve of the plow, the outer faces of all the parts lying flush, as shown. As the share is bolted to the moldboard face of the standard, a single bolt 19 will sufiice to secure the landside to the saddle, the peculiar interlocking engagement of the landside with the gunnel and the saddle preventing movement of the landside around the bolt.

If it be desired to use a share which is not formed with a gunnel, the same saddle and the same landside may be employed. In this instance, I provide a filler or false gunnel 20 to extend between the shoulder 21 on the share and the front end of the landside and preserve the continuity of the landside surface of the plow. This false gunnel is an irregular shaped plate of such thickness that, when it is placed against the saddle or standard, its outer face will be flush with sponds in shape to the recess 6 in which it fits snugly. In the projecting end of the wing is a countersunk opening 23 through which and a registering opening in the standard is inserted a bolt 24 to secure the plate to the standard. The front end of the plate presents a vertical shoulder 25 adapted to engage the shoulder 21 on the share, and from the upper end of said shoulder 25 the edge of the plate extends upwardly and rearwardly on a curve 26 corresponding to the rear curved edge of the cutter portion of the share. From the upper end of said curved portion, the edge of the plate extends downwardly and rearwardly, as at 27, to fit against the shoulder a on the saddle or standard and the shoulder 15 on the front end of the landside, while the rear end of the plate presents the vertical shoulder 28, to engage the front end of the landside, and the notch or cut-away corner 29 to engage the front end of the lug 8 on the saddle. It will be seen at once that the front end of the landside overlaps the wing 22 and thereby aids in holding the plate in position and, as the edges of the plate are beveled to correspond to the bevel of the abutting or engaging surfaces, the several parts will be interlocked so as to be firmly retained in their proper relative positions. It may be noted, further, that the provision of this false gunnel strengthens the plow at a employed on the point of the share to engage the saddle and the end of the landside and substitutes therefore a vertical shoulder bearing against a similar shoulder on the point of the share.

It will be noticed that the recess 6 and the wing engaging the same are of such shape that they gradually merge, toward their front ends, into the member with which they are formed. The recess can thus be carried close to the extremity of the saddle without decreasing the quantity of metal therein to such an extent as to dangerously weaken it. Furthermore, there is no obstacle to the location of the shoulder 4 and the lug 8 at the proper points to hold the gunnel and the landside in their relative positions while a sufficiently extended bearing face is provided to prevent dislocation of the false gunnel.

On the inner end of the landside member of the saddle, at the upper end thereof, is a short rib or elongated lug 30 having a convex surface and also curved from end to end to fit in the concave groove 31 in the side of the beam 32, the end of which is curved downwardly and secured to the lower por tion of the landside member of the saddle. The lower extremity of the beam is constructed with a lug 83 on its rear edge through which a bolt hole 34 extends, said bolt hole being countersunk at one end to fit over a conical boss 85 formed on the inner face of the landside member of the saddle around the opening which receives the bolt 19 while a notch or open-ended slot 36 is formed in the front side of the beam at the lower end thereof to engage a lug 37 on the saddle adjacent the bolt hole which receives the bolt 24, the slot being of sufficient length to embrace the sides of said bolt, so that the nut mounted thereon may be turned home against the foot or lower end of the beam. It will thus be seen that the forward bolt which fastens the beam to the saddle does not pass through the landside but is seated beam against the saddle. As a result of the.

described arrangement, the beam will not work loose under hard usage.

In the process of chilling moldboards the metal has a tendency to crack as it contracts, and it is also rendered more liable to break when in use, and in order to overcome such defects I form'on the back of the mold board button-like protuberances 38 which are arranged in irregular or staggered relation and extend over practically the entire rear surface of the moldboard, except a part thereof at the front which rests against the standard or saddle to which the moldboard is secured, and thereby cause the castings to shrink more uniformly, so that the percentage of fractures during the chilling process becomes so small as to be negligible while liability to breakage in practical use is reduced to a minimum, for the reason that at the start a fracture will encounter a protuberance, which is very hard to break through, and must take a zigzag course with consequent resistance. Moreover in the chilling process the protuberances do not always come out soft but each has a matted formation which prevents the fracture going through one, and it is either arrested or compelled to encounter great resistance by taking a zigzag course.

It will be readily seen from the foregoing description taken in connection with the accompanying drawings, that I have provided a plow, the parts of which are easily molded and fitted together and which, when together, will be interlocked, so that the plow will retain its original shape and not lose its suck and gather. Furthermore, the interchangeability of the parts is distinctly advantageous, as a dealer having a few parts may meet the demand for a wide variety of plows. For instance, with three points, the false gunnel, landside and saddle herein shown and described, together with a standard and landside disclosed in my application filed simultaneously herewith, any one of four distinct plows may be provided.

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