PATENT OFFICE.

ARTHUR FRANKE, OF CARY STATION, ILLINOIS.

TURNB'UCKLE.

Application filed October 31, 1923. lSerial No. 671,834.

To all whom t may concern:

Be it known that I, ARTHUR FRANKE, a citizen of the United States, and a resident of the town of Cary Station, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in a Turnbuckle; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon. which form a part of this specification.

This invention relatesto turnbuckles for taking up slack in wire ropes and the like, and has special reference to the requirements of airplane wiring wherein lightness and simplicity are paramount requirements.

It is an important object of this invention to provide a turnbuclile wherein the barrel can be easily and cheaply manufactured from sheet metal without the necessity of performing internal threading operations thereon.

It is another important object of this invention to provide a turnbuclle in which standard clevis and eye rod ends may be used with standard nuts secured in the barrel to furnish the adjustment.

Other and further important objects of this invention will be apparent from the disclosures in the drawings and accompanying specification.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a plan view of a single end turnbuckle embodying` the features of this invention.

Figure 2 is a side elevation thereof,

Figure 3 is a plan view of a double turn buckle.

Figure 4 is a section on the line 4 4 of Figure 3.

Figure 5 is a section on the line 5-5 of Figure 2.

As shown on the drawings:

The device of this invention comprises either an eye 6 or clevis 7, rod end threaded at 8 for standard nuts 9. As shown in Figure l, a wire rope 10 is passed through the eye rod end. The barrel 11 of the turnbuckle in the single turnbuckle is formed in a U- shape and apertured at the bottom 12 of the U for the threaded portion rod end. The sides 13 of the U adjacent the bottom of the bend are spaced to closely engage opposite faces of one of the nuts 9 and beyond the nut are brought closer together to touch the rod 8 beyond the nut to prevent undue wabble. The tips 14 of the legs of the barrel are apertured as at 15 to take a bolt 16 which engages with a suitable anchor 17.

In a double turnbuckle, one rod end is threaded right hand and one left hand and the barrel 18 is in essence two single barrels formed from one strip of sheet metal bent to the required form and the ends Welded or otherwise secured as shown at 19 in Figure 3.

With the single turnbuckle the bolt 16 must be removed and the barrel 11 rotated to screw the inner nut either way on the rod 8. FVith the double turnbuckle, loosening thc outer nuts will permit rotation of the barrel to 4tighten or loosen the turnbuckle without disturbing the fittings attached to the rod ends.

I am aware that many changes may be made, and numerous details of construction may be varied through a Wide range without departing from the principles of this invention, and I therefore do not purpose' limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

A turnbuclle comprising a metal strip bent into U-shape with an enlargedI section at the bend and apertured centrally of the U bend, a threaded rod extending through said aperture, and nuts on said rod inside and outside said metal strip, the nut inside being engaged by the enlarged section at the bend and the threaded rod being contacted and guided by the projecting ends of the metal strip.

In testimony whereof I have hereunto subscribed my name.

ARTHUR FRANKE.
