CAST-OFF CONSTRUCTION.

Specification of Letters Patent.

Application filed June 2, 1913.

Patented Feb. 3, 1914.

Serial No. 771,214.

To all whom it may concern:

Be it known that I, ERNEST N. HUMPHREY, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Cast-Off Construction, of which the following is a full, clear, and exact description.

This invention is designed to provide an improved form of cast-off device such as used in the suspender art and aims to provide a simple and eiiicient device of this character which may be readily and cheaply manufactured.

A preferable embodiment of the invention is described in detail in the following specification, taken in connection with the accompanying drawings illustrating such a preferable embodiment, and in which,

Figure 1 is a view in elevation of two separate and separable parts united by means of a cast-off construction embodying the present invention. Fig. 2 is a rear elevation of one of the parts shown in Fig. 1. Fig. 3 is a vertical section on the line aa of Fig. 1. Figs. 4 and 5 are details of construction of the forms of the device illustrated in Figs. 1-3. Fig. 6 is a view in front elevation of a cast-ofl' construction embodying a tubular cord guide. Fig. 7 is a vertical sectional view on the line 6-6, Fig. 6.

Referring to the drawings by numerals, 1 indicates one of the two separable parts which, in the present showing, forms a loop plate and is carried by the lower end of the shoulder strap of a suspender construction. This loop plate is provided with a headed stud 2 projecting outwardly therefrom, which stud is used as a means of connection between the loop plate and the other member of the cast-oif. This other member of the cast-off in the present showing constitutes the means of support for the strap or cord, which extends to and is attached to the supported garment. 3 designates a strap plate designed to receive such supporting straps, this plate being provided with one or more slots 4 therein through which the straps are threaded. The inner edge of the plate adjacent the upper slot is recessed as at 3 to receive a clasp member which is designed to cooperate with the stud 2 of the other member of the cast-0E. This clasp member in its specific embodiment is especially desirable from the commercial standpoint inasmuch as it may be readily formed from sheet metal stamped by appropriate mechanism. In Fig. 5 I have illustrated a metal blank from which the clasp member may be formed. This blank provides a central portion 5 and end portions 6 and 7, the latter being stamped to form a flange 8 extending around its edge, the end 6 being preferably of a size and shape to fit snugly within the flanged portion 8 of the opposite end when the blank is folded upon itself centrally of the middle portion 5 thereof.

In the form shown in Figs. 13, the portion 5 of the blank seats within the recessed edge 3* of the strap plate 3 and is clamped about the upper edge of said plate to securely engage the clasp member therewith. The ends 6 and 7 are each provided with complemental keyhole slots 9 therein which, when the blank is folded, are in alinement. These ends 6 and 7, when brought together, form a housing and are secured together preferably by means of tongues 10 and 11 formed integrally with the end 7 of the blank and folded over to engage and unite the end 6 therewith. This provides a space between the inner walls of the sides 6 and 7 of the housing within which space is seated a spring clasp member'comprising a base 12 seating between the inner extremities of the housing and having complemental spring arms 13 extending therefrom and lying in substantial alinement with and behind the edges of the walls of said housing adjacent the alined slots therein. These arms 13 are provided intermediate their ends and at the points corresponding to the points of contraction of the key-hole slots 9 with inwardly projecting locking shoulders 13 which project outbeyond the edges of the sides of said housing adjacent said keyhole slot. The base 12 of the spring clasp is recessed as at 12 to receive the tongue 11 when the same is bent thereover and extends to and is bent upon the outer face of the side f the housing. 7 This, therefore, secures the lower end of the spring clasp to the housing, but leaves its spring arms 13 free to yield. It will be noted that the edge of the end 6 is offset as at 15 to extend within the housing at a point above the upper edge of the arms 13 of the spring clasp and form a seat for the tongue 10 when the latter is bent over the upper edge of the part 6 to secure the two sides of the housing together.

The enlarged end of the alined keyhole slots 9 in the housing are slightly greater in diameter than that of the headed stud 2 so that the latter may be inserted through the enlarged end of these keyhole slots to project beyond the outer face of the housing, The part of the cast-oft carrying said housing may then be moved to bring the shank of the stud 2 within the upper and contract ed portion of the keyhole slots whereupon the locking shoulders 13 of the spring arms, which are spaced apart a distance less than the diameter of said stud shank, will snap in below said shank and detachably lock the shank in engagement with the housing at the upper edge of the keyhole slot, as shown particularly in Figs. 3 and 7. In order to separate the parts, it is only necessary to move the same relative to each other with slight force to bring the shank of the stud in the direction of the enlarged end 01 the keyhole slot of the housing, whereupon the arms 13 will. be spread apart and the head of the stud 2 brought within the enlarged end of the keyhole slot so that it may be withdrawn laterally therefrom and the two parts of the cast-ofi" separated.

Where the garment supporting straps are not used and cords are substituted, I may advantageously shape the middle portion of the sheet metal blank to provide a cord guide and thereby dispense entirely with the strap plate 3 shown in Figs. 13. The blank, when thus formed, will be folded upon itself and on a line transversely of the central portion of the blank to provide the tubular cord guide portion 1 1 of Figs. 6 and 7, the construction and parts of the blank being otherwise the same as those shown in Figs. 1-3, these parts being secured together in the same manner by means of the tongues 10 and 11. Such a construction of cord guide, it will be evident, is an especially advantageous one inasmuch as the tubular cord guide and attaching clasp may be formed from a single piece of sheet metal and at minimum manufacturing cost.

While I have herein described a prefen able embodiment of the invention, it will be obvious that various changes in the structure and relative arrangement of parts are possible within the spirit of the invention and the scope of the appended claim.

l hat I claim, therefore, and desire to secure by Letters Patent is:

In a garment supporter clasp, a sheet metal blank having similarly shaped end. portions each provided with a key-hole slot therein and having an intermediate portion, said blank being bent transversely on said intermediate portion to bring said end portions face to face with their slots in alinement, one of said end portions having a housing flange about its edges and having a locking tongue adjacent the enlarged end of its slotted portion, and the other of said end portions fitting within said housing flange, a spring clasp comprising a base and two integral spaced spring arms extending therefrom and having alined oppositely disposed and inwardly extending locking sh onlders thereon, said clasp being seated between said end portions with its base positioned below the enlarged ends of said alined slots, said locking tongue being clasped over the edge of the opposite end portion and over the edge of said clasp base to lock said end portions together, with the base of said clasp held therebetween, the locking shoulders of said clasp normally extending inwardly toward each other and beyond the inner edges of the narrower portion of the alined key-h ole slots, the ends of said spring arms being free and said arms being loosely inclosed within said end portion housing.
