Application filed February 3, 19,23.
To ZZ @cho/nt it may concern.'
Be it known that we, LOUIS J. S'roLr. and EnNns'r dorrnsoN, citizens of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Cylinder-Tooth l/Vrenches, of which the following is a specification.
This invention relates to` an improved cylinder tooth wrench and seeks, as one of its principal objects, to provide a wrench which may be readily slipped between the bars oi a threshing machine cylinder to engage the nuts upon the inner ends of the cylinder teeth and operated for tightening said nuts.
'Ihe invent-ion has as a further object to provide a wrench embodying means to accommodate a bar or the like which may be employed as a lever for turning the wrench.
And the invention has as a still further object to provide a wrench embodying means for straightening cylinder teeth.
Other and incidental objects will appear hereinafter.
In the drawings:
Figure lis a plan view showing our im proved wrench in use.
Figure 2 is a perspective view of the wrench.
Figure 3 is a detail elevation showing the manner in which the wrench is used for straightening a cylinder tooth, and
Figure 4 is a detail sectional view on the line 4 4 ol' Figure 3, looking in the direction of the arrows.
Referring now more particularly to the drawings, it will be seen that we employ a preferably cylindrical body bar 10 bent near one end thereof to define a laterally directed substantially semicircular bow 11 and integrally formed on or otherwise fixed upon the bar at its adjacent terminal is a socket 12. At its opposite end portion the bar is flattened to produce an eye 13 and projecting from the eye in substantial alinement with the bar are spaced parallel aws 14 having tlat inner faces, the flattened end portion of the bar being bifurcated beyond the eye to produce the jaws. As will be observed, the jaws, as well as the eye, lie in a plane with the bow 11 and straddling the Outer end portions of the jaws is a substantially U-shaped keeper 15. The keeper Serial No. 616,706.
may be welded or otherwise secured to the jaws so that the keeper will thus rigidly brace the jaws against spreading.
In Figure 1 of the drawings, we have shown the manner in which our improved wrench is used for tightening the nuts of the `teeth of a threshing machine cylinder. rlhe cylinder is indicated at 16 and the cylinder shaft at 17. As is customary, the cylinder is formed ot a plurality of longitudinal bars and mounted on said bars are the cylinder teeth, one Ot which is conventionally illustrated at 18. At its base, the tooth is provided with a reduced stud 19 extending through the adjacent bar of the cylinder and threaded on said stud is a nut 2O at the inner side of the bar securing the tooth in position. As illustrated, the body bar 10 of the wrench is inserted in the cylinder between adjacent bars thereot opposite the tooth 18 and the socket 12 engaged with the nut 20, the bow 11 being so positioned with respect to said socket that said bow will be disposed at the plane ofthe cylinder shaft 17. Accordingly, a bar or other lever may, as suggested in dotted lines in Figure 2, then be engaged through the eye '13 of the wrench, when said bar or lever may be operated for turning the wrench and tightening the nut, and since the eye lies in a plane with the bow the position of the bow with respect to the shaft 17 may be easily determined by observing the disposition of the eye. The nuts of all of the cylinder teeth may, of course, be tightened in like manner so that the tool will, in practical use, thus be found highly convenient as well as etiicient. The jaws 14 are provided in order that the tool may be employed for straightening cylinder teeth. To accomplish this operation the jaws are, as shown in Figure 3, engaged with the tooth to be straightened, a tooth being conventionally illustrated at 21, when j the body bar 10 ot the wrench may be used as a lever for bending the tooth. .Ars will be observed, the jaws are spa-ced apart to snugly accommodate the tooth therebetween while, as particularly brought out in Figure 4, the keeper 15 will abut an edge Ot the tooth for limiting the jaws against displacement therefrom. At the same time, the keeper will act to brace the jaws against the strain thereon during the bending Oper Y ation. Accordingly, the tool may be manip- Lesse-i3 uiated for straightening the tooth without Akeeper stladdling the free ends of 'the jews 10 fear of snapping off the jaws or disloozitto extend therebetween at Corresponding ingv the jaws from engagement with the side edges of the jaws bracing the jaws tooth. against spreading. 5 Having thus described the invention, In testimony whereof we affix oui' signawhet is claimed as new is: tures.
