UNITED STATES PATENT OFFICE.
LOUIS BERGE, OF FLINT, MICHIGAN, ASSIGNOR TO A C SPARK PLUG COMPANY, OF FLINT, MICHIGAN, A COMPANY OF MICHIGAN.
WORM-SHAFT MOUNTING.
Application led September 8, 1925.
This invention relates to a worm shaft mounting.
The object of the invention is to provide means to securely hold the shaft from movement along its longitudinal axis. A further object is to provide a simple expedient for holding the shaft by means which shall at once hold the shaft as stated and be locked by the shaft in its operative position.
The invention is shown as applied to a speedometer where a shaftI carried in bearings on the base, is held from movement on its longitudinal axis, but obviously it may be used in numerous relations where a shaft l5 must be held in position.
With these general objects in view. the invention is carried into leffect by the structure herein described and shown in the accompanying drawing.
In the drawing Figure 1 shows a plan view of a speedometer with the odometer removed.
Figure 2 is a section on line 2 2 of Figure l.
Figure 3 is a plate.
Referring to the drawing, there is shown at 5 the base of a speedometer. Upon this base are two bearings 7v and 9 for the so called second worm shaft 11. It is the purpose of this invention to provide a simple but effective means to hold this shaft from movement along its longitudinal axis. To that end a groove is formed in the shaft. as
shown at 13. Through the base opposite the groove is passed a locking plate 15, of subperspective of a locking Serial No. 55,111.
stantially U shape. The legs of the U surround the grooved portion of the shaft as will be readily seen. The dimension across the opening of the U is, however, very slightly less than the diameter of t-he reduced portion of the shaft. The plate 15, must, therefore, be snapped over the shaft when the members are assembled in position. Vhen thus positioned, it will be seen that no longitudinal movement of the shaft is possible and furthermore, because of the locking feature, the plate l5 can notA slip off the shaft and out through the base.
The device is very simple and affords veryY effective means to secure such a shaft. Its field of usefulness is very extensive and obviously is not limited to the single application herein described.
What I claim and desire to protect by Letters Patent is:
In an instrument, a base, lugs projecting from one side of said base, aA shaft journalled in said lugs, said shaft having a groove, said base having an aperture extending thereo through, a U-shaped fastening means eX- tending through said base aperture and engaging' said groove, the opening ofl the U being somewhat less than the diameter of the groove whereby longitudinal movement 05 of the shaft is prevented by the fastening means and whereby the `escape of the fastening means from the base is prevented by the engagement of the fastening means with the shaft. 7
In testimony whereof I aliX my signature.
LOUIS BERGE.
