CLASP DEVICE.

Application filed May 12, 1923. Serial No. 638,466.

This invention relates to clasp devicesand particularly to devices of this class designed for use in connection with vanity cases, small handbags, suitcases and the like; and the object of the invention is to provide a device of this class composed of separate parts fashioned from sheet metal or from suitably formed sheet metal blanks; a further object of the invention being to provide improved means for retaining the yoke or lock member of devices of this class in connection with one part thereof and for reinforcing that part of the clasp device in connection with which said yoke or lock member is mounted, a` still further object being to provide the crosshead of the yoke or lock member with means cooperating with a flat spring for retaining said member under tension in its operative position; andywith these andA other objects in view, the invention consists in a clasp device of the class and foi-.the purpose specified which is simple in construction and efficient in use, and which is constructed as hereinafter described and claimed and produced in accordance with the method hereinafter set out.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate part-s of my improvement are designated by suitable reference characters in eachjof the views, and in which Fig. l1 is a bottomplan view of mycomplete clasp device, detached.

Fig. 2, is a partial section on the line Of 1. i

Fig. 8 is a view similar to Fig. 2 but showing the `yoke or lock member in ajdifferent position.

Fig. 4 is a blank from which one part of my improved clasp device, is made. f

Fig. 5 is a sectional view of the clasp device showing the first step inthe process of forming the same:

Fig. 6 is a blank from which the yoke or lock member is formed.

Fig. 7 is a blank from which the other part. of the clasp device vis made.

' Fig. 8 is a perspective detail view of that part of the clasp device which is made from the blank shown in Fig.'7 and,

Fig. 9 is a plan view of the sheet metal spring which I employ.

My improved clasp device comprises two body portionslO and 11, and for the purpose of description, the body portion 10 will be regarded as the main body portion and 11 the supplemental body portion. I

also employ ayoke or lock member 12 and a sheet metal spring 13. In Fig. 4 of the drawing, I- have shown a blank l0a from which the main body portion 10 is formedI and this blank is of an irregular contour but one end is substantially semi-,circular 1n form as shown at -14 and provided with three equally spaced projecting fingers 15. The other end portion of the blank is mounted as shown at 16 `and provided at one sidev thereof with projecting curved 1ingers 17 having square shoulder portions 18 and at the oppositeside are arc-shaped recesses 19. In forming the main body por` tion 10, the blank 10a is formed from suitable dies and fashioned into the form shown in Fig. 5 of the drawing, or in other words, to form a cup-shaped body 20, which is arc'- shaped in form at one end as shown at 21 in Fig. 1 of the drawing, and the other end portion of which is reduced to form a projecting arc-shaped nose 22, and the lin-- gers 15 extend atright angles to thel top face 23 of the body portion 10 as do also the fingers 17 as shown in Fig. 5. l The arcshaped nose 22 .is hollow on its inner face or provided with a recess 24. 4

The Vsupplemental body portion l1 is formed from a blank -11a shown` in Fig. 7 of the drawing, and lthis blank is substantially semi-circular in form and provided with three equally spaced fingers 25, and

- in forming .the body portion 11, the blank 11 is fashioned intothe form shown in Fig. 8 of the drawing to form a substan-` tially arc-shape`d semi-circular body portion, and the straightl wall 26 thereof 1s apertured as shown at 27 to Ireceive the projecting nose 22 of the main' body'portion` 10 as learlygshowain Fi "e ,1 te e', inclusive, and the figersQ extend at right angles to the top face 28 of the body portion 1.1 as clearly shownin Fig.` 8.

The member 12v is blanhed from sheet metal into the form shown in Fig. 6 of the drawing, and the member112 is in the' .forni of a loop or yoke, arc-shaped in form at one end as shown at 29and provided with a slight projecting portion and the other end of which is connected by a transverse crosshead 31 having` an enlarged centrall portion 32, which projects at the opposite sides of the crosshead 31 as shown at 33 and 311. 1n completing the part 12 the crosshead portion thereof is bent at a slight angle L to the plane of said memberI as clearly shown in Figs. 2 and 3 of the drawing.

rihe spring" part 13 is composed of a strip rof spring metal, one end portion of which is I l rounded as shown at to conform with the curvature of the main body portion 10.01` the recess therein, and the otherend portion of said spring part is reduced to form a projecting androunded nose 36, which tstwithin the rece-ss 2st of the nose v22.

. In assembling the several parts of my im# proved clasp device, after said parts have .been fashioned in the manner above set out,

thespring part13 is first placed` within the main body portion 10 as shown in Figs. ,1 to 3 inclusive, after: which the' member 12 or the crosshead portion 31 thereof placed within the recesses 19 at the opposite sides of the body portion 10. and the projecting curved fingers 17 are then folded inwardly over and partially around the crosshead portion 31 of the member 12 as shown at 37 in Figs, 1 to 3 inclusive, to retain thein'embefr 12 against displacement from the main body portion 10 and also to hold said member in proper position in the recesses 19, and yet permit of the rotation or.. swinging move- .ment of the member in the (body por-Y tion 10.

It will be noted that when' the supplemental body portion 11 is mounted in connection with the main bodyport-ion 10 or when the nose 22 passes into the aperture 27 of the body portion 11 as shown in Figs. 1 to 3 inclusive. and the member 12 is moved into its closed and operative position .as shown in Figs. 1 and 2, that. said member is held firmly upon the body portion 11 under the tension of the spring 13,"said spring comprising` upwardly arranged projections 33 at one side of the enlargement 32 ofthe crosshead 31 as clearlyV shown in Fig. 2 of the drawing, and whenthe bodyportion 11 is removed, the yoke or lockmember 12 will assume a position ata slioht -angle to that shown in Fig. 2, in which position the face of rthe enlargement 32 will lieflat upon the spring 13. The member 12 may alsobe tensionally held in the position shown in Fig. 3j or maybe swung backwardly to lie upon the top face of the main body portion 10 if kwhat l claim as new and shown a specific method of forming the separate parts of vmy improved rclasp delvice, it will be understood that lam not necessarily limited in these respects and various changes in and modifications of the yconstruction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
