BLANK FOR LlFE-PRESERVERS.
SPECIFICATION forming part of Letters Patent No. 703,363, dated J 1113? 1, 1902.
Application filed December 2, 1901. Serial No. 84,420. (No model.)
To all whom it may concern:
Be it known that I, HACHIG A. AYVAD, a citizen of the United States of America, and a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Blanks for Life-Preservers, of which the following is a specification.
This invention relates to blanks for life-preservers, which are suitably connected in fours, so as to form the four quarters of a life-preserver of the class shown in my prior patent, No. 673,672, dated May 7, 1901.
The object of the invention is to produce such blanks easily and to lessen the cost of manufacture by lessening the waste of material.
To this end the invention consists of certain features of construction to be hereinafter described and then claimed.
In the accompanying drawings, Figure 1 is a plan showing how two blanks are cut with little waste. Fig. 2 is a plan showing two connected blanks, a portion of the front one being turned back to disclose the one behind. Fig. 3 is a plan showing four blanks connected to form the body of a life-preserver, portions of the front ones being turned back at the point where a suitable valve, not shown, is inserted to disclose the ones behind; and Fig. 4 is a section on line 4 4, Fig. 3.
Each blank of suitable fabric is composed of a main or lobe portion A and an extension or neck portion B. The extension portion is narrow and is located at one side of and in line with the corresponding edge a of the lobe portion A. From a point C at that side of the lobe portion opposite the extension B to a point D intermediate of these two sides the lobe portion A is formed with a convex curvature, While between said intermediate point D and a point E at the inner edge of the extension B the said lobe portion is formed with a corresponding concave curvature. It is evident that these curvatures may be of a greater or less radius and that the inner edge of the extension may also be straight for a greater or less distance from the point E to the inner corner of the end of the extension. The forma* tion at the inner edge of the lobe portion of one blank, which is joined with the inner edge of the narrow extension, is also present in the corresponding edge of another blank,as shown in Fig. 1, two blanks being formed from a piece of fabric of suitable shape by a cut followinga compound curve-such, for instance, as shown. In consequence of this cut the portion removed by forming a concave curvature in one blank becomes the convexlycurved portion of the other blank.
It will be apparent that by making two blanks from a piece of fabric in the described way no waste results, except possibly from material cut off to form round corners F, if desired. If the corners at]? are angular, there need be no waste, excepting at two diagonally opposite points G G.
To make up alife-preserver body,two blanks A are matched and secured together along the edges, and the two pairs of so-connected blanks are'secured together to form the body of the life-preserver, as shown in Figs. 3 and 4. A completed liferpreserver is not shown, but only the four blanks secured at their edges. The portions thrown back in Fig. 3 show where a valve is to be inserted.
What I claim as new and of my invention 1s- 1. A blank for life-preserver's, such blank consisting of a main portion and a narrow extension in line with one edge of the same, substantially as described.
2. A blank for life-preservers, such blank consisting of a main portion and a narrow extension in line with one edge, the edge of the main portion, which is joined with the inner edge of. the extension, having two similar curves, one being convex and the other concave, substantially as described.
Signed at New York, N. Y. this 27th day of November, 1901.
