Patented May 19, 1942 i 'rHREsHEn Albert B. Welty, Moline, Ill., assignor to International Harvester Company, a corporation of New Jersey Application September 23, 1940, Serial No. 357,919
Claims.
This invention relates to improvementsgin the construction of the cylinder which is used in harvester threshers.
It is desirable to provide acylinder for a harvester thresher which is Alight in Weight, but strong enough to withstand severevuse.
It is also desirable to have a cylinder'which can be readily converted from a rasp bartype into a tooth type or a flal bar type of cylinder.
It is, therefore, an important `object of the present invention to provide a cylinder which is lighter in weight than previous cylinders, but which is much stronger and easier to manufacture.
Another object of the invention .is to provide a cylinder which may be readily changed from a ail bar cylinder to a rasp bar-cylinder or a tooth type of cylinder.
Another object of the present invention 'is'to provide a cylinder which may be easily assembled.A
According to the present invention, the cylinder comprises a cylinder shaft on which are mounted cylinder head plates in which-a plurality of converging slots are provided. A cylinder bar support having the edges thereof bent downwardly is inserted in the converging slots of the cylinder head plates and is secured thereto by welding. By virtue of this construction an efficient light weight, but much stronger cylinder is provided, which is especially advantageous in small types of harvester threshers. The cylinder is also much easier to assemble and manu- These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description of the preferred structural embodiment taken in conjunction with the accompanying drawing.
In the drawing:
Figure 1 is a side view of one of the cylinder head end plates;
Figure 2 is an end View of the center cylinder head plate;
Figure 3 is an end view of one of the cylinder head end plates; K
Figure 4 is a side View of the novel assembled cylinder; and,
Figure 5 is an enlarged end view, showing the welds which secure the cylinder bar support to the cylinder head plate.
Referring now to the drawing, and more particularly to Figure 1, there is shown one of the cylinder head end plates I0, which is hexagonal in shape. In each of the sides of the cylinder head plate I0 is provided a pair of reentrant portions or converging recesses II. The center of the plate I0 is provided with an openingV I2, vin
which is inserted a hub member I2a which is secured theretoby a plurality of rivets I3. Akeyway I4 is provided Within an opening I2bv in the l.
hub-member I2a. The-center cylinder .head plate I5 is shown in Figure 2 and issubstantially of the same shape as the end cylinder head plate -I IJ except that only an opening lais provided atthe center thereof.
The cylinder head end plates I 'andone of the cylinder head center plates I5Y are inserted `on a shaft I6 in which there is provided alined keyways II. The slots in theA cylinder head plates I0 and I5 are in alinement. 'A key I8 is inserted in the keyway I'I Vin the shaft I6 and the keywayl I4 in the hubL I2. The key I8 securesrthe cylinder head end plates I0 to the cylinder shaft I6.
After the key I8 has been inserted in thekeyways I4 and I1, it is locked-therein by a chisel mark in the shaft at the rear of the head portion thereof. The center cylinder head plate I5 is not secured tothe cylinderfshaft I6.
A plurality of cylinder bar supportsintheform Y of rectangular plates I9 areassociated with the cylinder head plates I0 and |15. v'IheLcylinder bar support I9 comprises a longitudinal plate'member having a flat surface 2I`, the outer edges of which are bent downwardly, as at 22. The angle of the flanges 22 is substantially the same as the angle of the converging slots II in the cylinder head plates IU and I5. The cylinder'bar supports I9 are inserted in the converging recesses VII of the cylinder head plates I0 and I5, as shown in Figure 5. It is to be noted from' Figure 5 that, when the cylinder bar supports I9 are'inserted in the slots I I, the outer edge of each of the anges 22 contact the outer edge of the slots Il, and the inner portion of flat surface 2I contacts the flat portion of the cylinder head plates I0 and I5 between the slots II. In this way the cylinder bar supports I9 are held in position with respect to the cylinder head plates I0 and I5. After the cylinder bar supports I9 have been inserted in the alined recesses II in the cylinder head end plates l0 and the cylinder head center plate I5, the outer edge of the anges 22 are welded to the cylinder head plates I0 and Y port I9 against lateral movement with respect to the cylinder head plates I and I5.
On the fiat surface 2I of the cylinder bar support I 9 may be secured any preferred type of threshing means. As shown in Figure 5, a rasp bar 25 is secured to the flat surface 2| in which are provided a plurality of openings 26. A bolt 2'I is inserted in suitable openings provided in the rasp bar 25 and the openings 26 in the cylinder bar support I9. A nut 28 is provided on the bolt 21 so as to secure the rasp bar 25 to the flat surface 2 I. While the rasp bar has been shown attached to the cylinder bar support I9, it is to be be shapedby a single punching operation, and
the cylinder bar supports can likewise be prepared `by'a single punching and bending operation. The cylinder bar I9V is supported intermediate the cylinder head end plates ID by the center cylinder head plate I5 which is welded to thecylinder bar support I9 in the same manner as `the cylinder head end plates I0.
While only the" preferred structurall embodiment ofthe present invention has been shown, it is to be understood that the invention is not to be limited to the specific details shown and" described, but that widely different means may be employed in the practice of the broader aspects of my invention.
What is claimed is:
1. A cylinder construction comprising a shaft,V
a plurality of plates secured to the shaft at spaced points, the outer periphery of the plates having a plurality of pairs of converging recesses formed therein, and a plurality of bars each having'a pair of flanges adapted to engage the recesses in said plates in such a manner that the outer edge of the flanges contactsthe outer edge of each flange contacts the outer edge of the recesses and the inner portions of the cylinder bars contact the portion of the plates between the recesses, and means for securing the cylinder bars to the plates.
3. A cylinder construction for threshers comprising a shaft, `a plurality of hexagonal shaped plates secured at spaced points to the shaft, said plateshaving a pair of converging recesses provided in eachside thereof, and cylinder bars having a pair of flanges inserted in the recesses in such a manner that the outer edge of each flange contacts the outer edge of the recesses and the inner portion of the .cylinder bars bctween the iianges contacts the portion of the plates between the recesses, and said cylinder being vsecured at their pointsof contact with the plate by welding. t
4. In combination, a shaft, a pair of hexagonal shaped end plates secured on the shaft, hexagonal shaped plates positioned on the shaft intermediate the end plates, said plates having a pair of outwardly converging recesses provided in each of the sides' thereof, and bars having a pair of downwardly extending flanges inserted in the recesses in the plates and being secured thereto by welding.
5. 'In combination, a shaft, a plurality of polygonalshaped plates secured at spaced points to the shaft and having a pair of outwardly converging recesses provided in each of the sides thereof, bars having `downwardly extending flanges inserted in the recesses in the plates and being welded to the plates, and threshing means secured on'said bars.
