INVENTOR. JOHN LEYENBERGER ATTORNEY.
United States CROSS WIRE PIVOT FOR SHAFT Application July 16, 1957, Serial No. 672,327
8 Claims. (Cl. 308-2) The present invention relates to a pivot for permitting a shaft to rotate through a small angle, and particularly to a cross wire pivot for permitting a shaft to rotate through a small angle.
The main object of the present invention is the provision of a new and improved pivot for permitting shafts to rotate through small angles.
Another object of the present invention is the provision of a new and improved pivot for permitting shafts to rotate through small angles and to prevent lateral movement of said shafts. v
Still another object of the present invention is the provision of a new and improved pivot for permitting shafts to rotate through small angles, which pivot is simple and inexpensive to fabricate.
A better understanding of the present invention may be had from the following detailed description when read in connection with the accompanying drawing, in which:
Fig. 1 is a perspective view of a shaft mounted on a pivot embodying the present invention; and
Fig. 2 is a sectional view taken along the line 22 of Fig. 1.
Referring now to the drawing in detail, a shaft 10 is mounted for rotation through a small angle on a cross wire pivot 12 embodying the present invention.
The cross wire pivot 12 has sufficient resiliency or give to permit rotation of shaft 10 through small angles. However, with the wires 28 and 36 provided as shown, shaft 10 will rotate about an axis running through the projected point of intersection of the wires 28 and 36. Moreover, the pivot 12 will permit no transverse movement of shaft 10 and only rotary movement can be imparted to said shaft. The prevention of transverse moveatent p 2,912,287 Patented Nov. 10, 9
ment of the shaft results from the fact that each wire acts as a stop against movement of the shaft along the transverse axis of the other wire.
The present invention thus provides a frictionless type of pivot for the shaft 10 that will permit the shaft to be rotated through small angles and which will further prevent lateral movement of the shaft from occurring While such angular rotation is taking place.
