I 0 (ZZZ who m may concern:
Be it known that we, GOTTLOB FniisuL and lineman EioI-niiin, who were formerly subjects of the tlermanEmpire, but who have severally renounced. all allegiance to said power and declared our intentions of be coming; citizens of the United States, resid ing in Brooklyn, inthe county of Kings and State of New York, have invented certain new and useful Improvements in Keys, of which the following is a specification.
Our invention relates to an improvement in keys; particularly keys forgsecuring part of a mechanical construction in adjusted position.
An object of our invention is to provide a key having a portion that is especially adapted to engage the part or member to be secured and maintain it in the position desired. i
Other objects and advantages of our in ventionare set forth in the following description, taken in connection with the drawings, which disclose the best form of our invention nowknownto us; and the characteristics of our invention are precisely de fined in the appended claim. This disclosure, however, is explanatory only, and we may employembodiments of our invention other than what is actually shown herein, but within the scope and spirit of our in vention as the same isindicated by the general meanings of the terms in which the claim is expressed and by the variations in the phrasing of the same.
On the drawings: t
Figure l is a side view of a key according to our invention;
Figure 2 is a rear end view and Figure 3 a front end view of same; and
Figure f is a view showing the key in operative positiom'with the part held by it, :insection.
The same numerals identify the same parts throughout. Our key is shown at 1 with a kerf 2 at one end, and threads 3 at the other. Instead of a kerf, the key may be otherwise shaped to enable a tool to be utilized to turn the key. Between the ends of the key is a portion 4, having projections 5, to roughen it. The key may taper towards the threads 3, and the portion 4 is preferably conical, with the projections 5 in the form of points or ribs,
ta impart a frictional surface to the portion 4 and make this portion capable of en; gaging the part to be secured, in. a proper and eilicient manner. lnpractice the key is put into use as illus tratedin Figure 4-, That view shows a bearsleeveor member 6, having an eccentric bore, and being encircled on its exterior by a groove '7. Usually the'sleeve 6 1S slipped on a shalt, not shown and is disposed in a bushing 8, placed in a support 9. This bushing per-.
mits the sleeve 6 to be adjusted therein by turning the sleeve and two keys accordmg to our invention, are employed to hold the sleeve 6 fast after the desired adjust" ment is obtained. At the upper end the bushing 8 has a groove 10, and at its lower end it has a recess 11. through the lower end of the bushing and is intended to register with the adjacent portion of the groove 7. The grooves 7 and 10 vertical or transverse plane with respect to the axis of the sleeve 6; and the keys 1 are inserted through bores 12 in the support 9, one to engage the grove 10 and the other to enter both the groove 7 and recess 1].. hen turned up, one of these keys will cause its projections 5 to be pressed tightly against the bushing 8 al')ove, and the other will similarly bind with its projections 5 extending through the recess 11 in. the bushing 8 against the surface of the groove 7 below; and thus the member 6 will be held against movement. Of course the bores 12 are in the same plane as the grooves 7 and 10 and re- .cess ll. i
The shaft mounted. inthe sleeve 6 will ordinarily be the distributer shaft of a mag neto for the ignition system of an internal combustion engine, although our invention is by no means limited to such a device, but may be employed in connection with many other constructions. When it is desired to adjust the position of the shaft in this sleeve, as by moving its axis up or down with reference to Figure 41:, the lower key 1 is loosened and the sleeve turned; and then the lower key is again tightened to make its projections 5 press firmly against the surface of the groove 7. Then the sleeve 6 cannot be moved, and the position of the shaft remains fixed till the operator once more turns back the key 1.
This recess extends w and the recess 11 are preferably in the same It "will be noted that the upper end of the bushing 8 is thicker than the lower end. Therefore, if one has to move the axis of the shaft in the sleeve 6 a relatively great distance upward, he can take out both keys and invert the bushing 8. The sleeve 6 will then be carried higlieigend the upper key will be the one binding in the groove 7 the lower key engaging with the groove 10, which will now be at the bottom. Adjustment of the sleeve 6 can be had in this case, asbefore, by loosening the upper key, turnmg the sleeve and again tightening the upper bolt.
A key as above described can be easily and quickly made either by cutting threads, ribs or ridges on the portion 4: or by punching this portion to provide points 5 as shown; ends key of this type co-operates excelsubstantially surroun ding :1 part of said [Min 1 tion to provide a frictional surface to engage and hold a member in a, desired position.
In testimony whereof, we have signed our nznnes to this specification this 22nd day of May, 1919.
