Specification of Letters Patent.

Patented Aug. '7, 1917.

To all whom t may concern:

Be it known that I, JAMES I'I. SAGER, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Bumpers, of which the following is a specification.

The present invention relates to bumpers and more particularly to the type used on automobiles, an object of this invention being to provide means for attaching a channeled bumper bar to its supporting arms in such a manner that effective connection between the bar and its arms is secured.

To this and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings Figure l is a plan view of a portion of the bumper lbar and one of its supporting arms;

Fig. 2 is a section on the line a-a, Fig. l;

gig. 3 is a section on the line 6 5, Fig. 2; an Fig 4 is a sectional view similar to Fig. 2, showing another form of bumper bar.

In securing bumper bars to their supporting arms, it is desirable that the fastening means between the bar and its arms shall not be visible at the front or the top of said bar.V This result has been secured before, but the means by which it has been accomplished has depended entirely upon the lower flange of the channel bar. According to this invention the anges of the channel bar are both engaged by, or held to, the supporting arm without perforating the upper iange.

Referring more particularly to the drawings, l indicates the channeled bumper bar and 2 its supporting arm. The lower flange or wall of the bar 1s provided with a slot 3 and through this slot a screwk 4 passes loosely. This screw is threaded through the forward end of the supporting armV 2 and has an upper cupped end 5 abutting the inner face of the upper wall or flange of the bar 1. By this arrangement, the inner face of the lower wall of the bar l is forced into firm contact with the under side of the forward end of the supporting arm 2, while the upper cupped end 5 of the screw firmly engages the inner face of the upper wall of the bar. A lock nut 6, arranged on the screw or bolt 4, engages the outer face of the lower wall of the channel bar l and holdsl the screw against movement in the slotB. By this arrangement, the bumper supporting arms are rmly engaged with the channel bar, the slots 3 permitting the ydistances between the supporting arms 1 to be varied slightly. In the modification shown in Fig. 4, the channeled bumper bar has its front wall 1a in the shape of a half of a diamond.

From the foregoing, it will be seen that the bumper bar is firmly secured to its sup porting arms by both of its flanges, without perforating the upper flange. Y

What I claim as my invention andv desire to secure by Letters Patent is 1. In a bumper, a supporting arm, a channeled bumper bar receiving the forwardy end of the arm, and a screw passed through one wall of the bumper bar and threaded through the bumper arm, one end of the screw abutting the inner face of the wall of the bumper arm opposite that through which the screw passes.

2. In a bumper, a supporting arm, a chanl neled bumper bar having a slot in one wall and receiving one end of the bumper arm, a screw passed through the slot and threaded through the arm, an end of the screw abut-v ting the inner face of the wall of the bar opposite that provided with the slot, and a nut on the screw for engaging the outer face of the slotted wall of the bar. v
