ELY BOCKSHE, OF MILWAUKEE, WISCONSIN, ASSIGNOR T MODERN GRINDER MFG. C0., OF MILWAUKEE, WISCONSIN, A CORPORATION 0F WISCONSIN.
GRINDER.
Application filed February 28, 1922.
T o all whom it 'may concern Be it known that I, ELY BosirsHn, a citi- Zen of the United States, and resident of Milwaukee. in the county of Milwaukee and State of lWisconsin, have invented certain new and useful Improvements in Grinders;
and do hereby declare that the following is a full, clear, and exact description thereof'.
The invention relates to grinders of the type on which Fatent No. 1.006.026 was issued to J. M. Thompson` Oct. '17, llll. for gear casing.
In the patent, the bearings for the grinding wheel shaft and the big gear shaft are all in one casting which is subjected to considerable strain and which cannot be readily replaced in case of breakage. The hearing for the grinding wheel is between the wheel and the gear 'for rotating saine, and the bearing for the big gear shaft is entirely between the big gear and the crank arm. Thus for each of the shafts, only one bearing is provided. The provision of one bearing only is such that on Wear. an angling ol the shafts result. While this defect may be removed to a great extent by lengthening the bearings, the gear must then be made in a substantially conical shape, as shown in Figure 4 of the patent. Such a gear is diftlcult to construct and its shape necessitates the elongation of arms 25 and 26 with the consequently distant spacing of the point of support on the table from the crank arm. Thus when force is applied to the crank arm, there is an action of excessive leverage on the point of support.
Applieants device comprises a grindingT Wheel shaft supported on a pair of hearings between which is positioned a pinion for rotating the shaft; a casing integral with the bearings, and having a side and peripheral wall, the side Wall beingr integral with one of a. pair of bearings supporting the shaft on which the crank arm is mounted. A second bearingr is provided for this shaft integral with a .cap for completely closing the casing, thus two bearings are provided for each shaft.
This structure effectively obviatcs tendency to angle, and the large gear is substantially flat, the supporting arms being Serial No. 539,990.
relatively close to the crank arm so that less leverage is developed.
W'ith the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction. combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claim` itbeing understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.
ln the accompanying drawing, l have illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode l have so far devised for the practical application of the principles thereof, and in which Figure 1 shows a cross section substantially on the line 1-1 of Figure 2, illustrating the device, and
Figure 2 shows a side elevation with the grinding wheel removed.
1 claim:
The combination of a shaft, a grinding wheel thereon, a gear rigid With said shaft. a pair of bearings for said shaft on either side of said gear` a peripheral wall of a casing and av side wall thereof, a substantially Hat second gear, meshing'with said first mentioned gear, a second shaft rigid with said second gear, laterally extending from huh sides therein?, :i third hearing fur one enel nf Said Shaft outwardly extending from said side wzli, n. Crunk en snifl second shaft, Amid paix' of hearings, Suid peripheral wail, said side` wail4V and 'sa'n'L-thrdi 'hearing heingintegmlly united, a cover. means se Curing Suhl em'ei to siil peripheral waiil und :i fourh. bearing integral therewith supporting the Othel` end of Said second Shaft.
In testimony that I claim the foregoing 10 I have hereunto Set my hund at Milwaukee.
