MATT STROM ANJD ERTCK HIOGLU'ND, DULUTH, litlINNESOTA.
SOIL-CULTIVATING: TOOL.
To all whom it may concern:
Be it known that we, MATT El'rRoM and Enron HoeLUNn, citizens of the United States and of Russia, respectively, both residing at Duluth, in the county of St. Louis and Eiltate of Minnesota, have invented cer tain new and useful improvements in Soiltlultivating Tools, of Which the following is a sper-ilication, reference being had therein to the accompanying drawing.
This invention relates to improvements in rotary soil cultivating tools, such as disclosed in our United States Patent No. 1,155,289 of September 28th, 1915, and has special reference to novel means for holding in operative position the two part blades employed in such cultivators.
The principal object of our present invention is to provide more simple and practical means for holding the sections of the blades in their respective position upon the rotating shafts of the cultivator.
Other objects and advantages of the in vention will appear in the further descrip tion thereof.
Referring to the accompanying drawing forming part of this application and in which like reference characters indicate like parts: i c
Figure 1 is a vertical sectional view through a fragmental portion of a tool sup porting shaft having two of our improved hubs mounted thereupon;
Figure 2 is a side elevation of one of the hubs .With the soil cultivating blade removed;
Figure 3 is a side elevation of the inside face of one side of one of the hubs;
Figure 4 is a side elevation of the inside face of one side of'o'ne of the hubs, showing the blades arranged. at a different angle in relation to the shaft;
Figure 5 is a side elevation of one of the blades attached within the hub; and
Figure 6 is an edge elevation of one of the blades apart from the hub.
The separable hubs each comprise two like halves l and 2, mounted upon the square ro tative cultivator shaft 8. These halves are alike in form and are provided with diametrically disposed cut-away portions 3 in the cooperative faces thereof said portions being the exact width of the shanks 4 of the Elpecifieation cf Letters Patent.

Application filed March 8, 1921. Serial No. 4250,5595.
blades 5, and when the halves are assembled upon the shaft 8 the cut-away portions 3 are arranged diametrically opposite so that the blades assembled in one half extend diametrically opposite to those in the other half. Each pair of blades are carried in their respective halves and abut the shaft 8 either squarely or on one side thereof, or on the corner as shown in Figures 3 and 4;. I
The shank 4 of each blade 5 is provided, by drop forging, (they being wrought blades), with a concavo convex tit 7, the convex portion of which when assembled intermediate of the halves of the hub register with the concaved recess 9 in one half, while the concaved portion of the tit registers with a convex portion or tit 6 formed in the cutaway portion of the opposite half, thus each blade is firmly held in the cut-away portion intermediate of the halves and positively by both halves, said halves having no registrable portions.
Having thus described our inventon, what we claim and desire to secure by Letters Patent, is:
1. The combination with a two part hub of the class described having diametrically disposed recesses in each half thereof, of two part blades having shanks registrable within said cut-away portions said shanks being provided with concavo convex tits thereupon registrable within depressions in one half and tits within the other half.
2. The combination with a two part hub of the class described having diametrically disposed recesses in each half thereof, of two part blades having shanks registrable within said cut-away portions, said shanks being provided with concavo convex tits thereupon, tits within the cutaway portions of one half registering with the concave portion of the tits in the blade and recesses within the non cut-away portions of the other half for registration with the convex portion of the tits in the blade.
3. The combination with a two part cultivator hub of the character described each part having a diametrically disposed cut away portion non-registrable with the portion in the other part, of opposed recesses and tits in the cooperative faces of the two parts, and two part blades having shanks provided with concavo convex tits therein which are cooperatively engaged with the our signatures In the presence of two wit-- recesses and tits in the parts of the hub nesses.
when united whereby the shanks or" each pair of blades are housed only in one partof the hub but held positively against dis- Witnesses:
lodgrnent by both parts thereof. Tues. OLArsoN,
In testimony whereof We hereunto afiix C. P. mnnnsoN.
