Description

Patented Dec. 1, 1925 UNITED STATES HENRY F. SCHULTE, 0F GRAND RAPIDS, MICHIGAN.

PIVOT PIN.

Application filed February 13, 1924.

To all whom it may concern:

Be it known that I, HENRY F. SCHULTE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Pivot Pins, of which the following is a specification.

The present invention relates to pivot pins; and its object is to provide a device of that character which may be readily applied in practice, and when applied shall be securely held in place; and which may be easily and economically constructed.

This object is attained by the structure hereinafter particularly described, and illus trated by the accompanying drawings, in which Figure 1 is a side view of a pivot pin, partially sectioned axially, members connected thereby being shown sectioned on the same plane;

Figure 2 is a side view of the pivot pin viewed from another direction;

Figure 3 is a sectional view thereof, taken 011 line 33 of Figure 2; and

Figure l is a sectional View of the same taken on line 4:'l of Figure 1.

Two or more members 1 having round bearings or openings 2 therethrough are shown connected by my device, which comprises a bolt 3 thrust cndwise through said openings and having a head 4:. This bolt is provided with a groove 5 extending in its longitudinal direction. This groove has an open end 7 at the headed end ofthe bolt, and the bottom of the groove adjacent the bolts other end 8 is inclined outwardly as shown at 9. A bendable rod 10, of soft iron or the like, is thrust endwise into the grooves open end 7 adjacent one side 11 of the members 1 and Serial No. 692,528.

is driven along the groove by a hammer or the like, until its inner end portion 12 is bent outwardly by engaging and sliding along the grooves inclined bottom, and until the mner extremity 13 of the rod projects from the groove beyond the opposite side 1 1 of the members 1. It will be seen that the pivot pin or bolt 3 is now held by this projecting bent portion of the rod from being withdrawn from the openings or bearings 2, although the rod may be driven reversely and thus straightened by blows upon its e2; tremity 13. It is also clear that the bolt 3 may freely turn in the bearings 2 in any longitudinal position of the bolt therein. The rod is desirably provided with a head 16.

I claim:

In combination with a member having an opening t-hercthrough, a device of the character described freely turnablc in said opening and comprising: a bolt thrust cndwisc through said opening andprovided with a groove extending in the bolts longitudinal direction and having an open end at one end of the bolt and having its bottom in the bolt, said bottom being inclined outwardly adjacent the other end of the bolt; a bendable rod thrust endwise into the grooves open end adjacent one side of said member and driven along the groove to a position in which its inner end portion is bent out wardly by engaging the grooves inclined bottom and its inner extremity projects from the groove beyond the opposite side of said member.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 8th day of February, 1924:.

HENRY F. SCHULTE,
