J. H. SIMPSON. BLANK FOR TURN BUGKLBS.
Patented May 7. 1889.
UNITED STATEs PATENT OFFICE.
JAMES H. SIMPSON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO OARNEGIE, PHIPPS & COMPANY, (LIMITED,) OF SAME PLACE.
BLANK FOR TU RN-BUCKLE&
SPECIFICATION forming part of Letters Patent No. 402,691, dated May '7, 1889. Application filed July "7, 1888. Serial No. 279,277. (No model.)
To all whom it may concern:
Be it known that I, JAMES H. SIMPSON, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Blanks for Turn- Buckles; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is aplan view of a blank adapted for the manufacture of turn buckles and formed in accordance with my invention. Fig. 2 is a horizontal section thereof. Fig. 3 is a side View of a finished turn-buckle made from one of my improved blanks. Fig. 4 is a vertical longitudinal section of the dies by which the blank may be fiattened and showing the blank therein.
Like symbols of reference indicate like parts in the drawings wherever they occur.
In the fornation of my improved blank I take a piece of metal, preferably tubular or hollow in form, and divide or cut it longitudinally between its' ends to form the strap portions. The blank so fol-med is a turn-buckle in embryo, having end portions of which the nuts are constit-uted, and separated side portions whichform the straps.
The blank shown in Fig. 1 consists of a tubular piece of metal, a, fiattened in the middle portion, having cylin drical and hollow end portions, b, the fiattened middle portion being cut or divided longitudinally to form the separated straps. Iu making this blank I take a hollow or tubular piece of metal, a', preferablyinsert therein a metal fi-llingpiece, c, and flatten the middle portion between suitable dies, d. The fiattened middle portion is then cut longitudinally to form the separated strap portions e, as shown in Figs.
1 and 2. The blank thus made may be forged subsequently into the shape of the finished buckle shown in Fig. 3 by means of suitable dies-such, for example, as those shown in a certain pendin g application, Serial No. .272,756.
My invention is not limited precisely to the form of blank herein shown and described, but is susceptble of various modifications, and is stated succinctly in the following claims.
The blank possesses many intrinsic advantages. It affords an article of commerce from which turrbuckles may be made with little cost, and the turn-buckles produced thereby are very strong and well proportioned. I believe that I am the first to make a hollow or tubular turn-buckle blank of any form in cross-section flattened or reduced at the middle portion comparatively with the end portions, and divided longitudinally between the end portions, and also the first to provide a blank made of a hollow piece of metal divided longitudinally between the ends, and intend to claim the same broadly.
I claim- 1. A blank for turn-buckles, consisting of a hollow or tubular piece of metal divided longitudinally in its middle portion between the ends, substantially as and for the purposes described.
2. A' blank for turn-buckles, consisting of a hollow or tubular piece of metal having a fiattened middle portion which is dividedlongitudinally, substa'tially as and for the purposes described.
In testimony whereof I have hereunto set 7 my hand this 7th day of June, A. D. 1888.
