' REPLACEABLI: 'IMPLEMENT PART Filed Aug; 12, 1957 I g/ 14 j? j? REPLACEABLE IMPLEMENT PART Donald F. Christoiferson, Stockton, Calif., assignor to International Harvester Company, Chicago, Ill., a corporation of New Jersey Application August 12, 1957, Serial No. 677,522 9 Claims. (Cl. 172-753) Other objects and advantages of the invention will` become clear from the following detailed description when read in conjunction with the accompanying drawings, wherein:
Figure 1 is a view in side elevation, partly in section,
of a subsoiler incorporating the features of this invention;
Figure 2 is a section, with parts removed, taken on the line 2-2 of Figure 1;
Figure 3 is a section taken on the line 3-3 of Figure 1;
Figure 4 is a section taken on the line 4-4 of Figure 1; and
Figure 5 is a View similar to Figure 1 with the parts disassembled.
In the drawings the numeral designates a vertical shank or standard, the lower end of which is bent forwardly to form a tapered or wedge-shaped foot section 11.
A cultivator shovel or earth-penetrating tooth 12 comprises a shoe 13 having a toe 14 at its forward end and a rearwardly directed tapered socket 1S shaped to conform generally to the shape of foot 11 of standard 10.
Figure 5 shows the manner of inserting point 22 of the earth-penetrating tooth in opening 19 of the shoe 13 and also the partial reception of foot 11 of the shank or standard 10 in socket 15. Figure 1 shows the parts assembled with toe 14 received in groove 23 of the point and with the forward edge of foot 11 engaging the lower edge of the rear end of extension 21, the upper edge of which engages the lower surface of upper wall 18 of the shoe. Point 22 is thus locked in place by the wedging action of foot 11.
Figure 5 shows an opening 26 in the foot 11 and a.
A'United States Patent ice vertical slot 27 in the side walls of shoe 13. Figure l shows these apertures to be in registry when the parts are properly assembled and adapted to receive a pin 28 held in place by washers 29 and cotter keys 30. ,f
Also forming a part of the earth-working tool of this invention is a separable shin 31, the lower end of which is curved forwardly and is receivable in the space between the upper edge of foot 11 and the inner surface of upper wall 18 of the shoe where it is securely held. The upper end of the shin 31 may, if desired, be further secured to the standard 10 by one or more clips 32.
Most of the wear upon an implement of the type shown and described is taken upon the point 22 although the shin 31 is also subject to considerable wear. It is readily observed that the point 22 is easily replaceable and is held in place without the use of bolts and pins. It is replaced by removing pin 28, sliding shoe 13 forwardly and withdrawing the point 22 for sharpening or replacement. Due to the tremendous size and weight of an implement of this type, the economic advantages of a replaceable wear point are obvious as well as the saving in time and labor involved in replacing a point.
The construction and operation of the invention should be clearly understood from the foregoing description. It should likewise be understood that the invention has been described in its preferred embodiment and that modifications may be made therein without departing from the spirit of the invention or the scope of the appended claims.
