Application filed. August 16, 1920. Serial No. 403,658.
T 0 @ZZ w from it may concern:
Be it lrnown that l, CYRUS B. MERRIAM, a citizen ot the United States of A.merica, residing at ietroit, in the county ot' Wayne and State ci Michigan, have invented certain new and useful improvements in Fasteners, oi? which the `following is a specification, reference being hadv therein to the accompanying drawings.
lnmy Patent No. 1337938, granted April 20, 1920, there is disclosed a fastener that may be advantageously used as automobile hardware for ot side curtains, panels, or other members adapted to cooperate with an automobile top in providing an inclosure for the upper portion ofthe automobile'body.
This invention relates to the-same class of fasteners and includes certain improvements which simplify the construction of the fastener, reduces the expense oi manufacture, and somewhat enhances the appearance of the fastener.
My improvements will be hereinafter more fully considered and then claimed, and reference will now be had to the drawing, wherein- Figure 1 is a front elevation of the fastener in an open position;
Fig. 2 is a longitudinal sectional view of the same:
Fig. 3 Vis a Jfront elevation of the fastener in a closed position;
Fig. 4 is a longitudinal a portion of the same;
Fig. 5 is a cross sectional view of a detached rotatable member;
Fig.' 6 is a perspective view of a detached steering member;
Fig. 7 is a 'front elevation o' a fastener showing a slight modification of my invention, and
Fig, 8 is a cross sectional view of the same.
In the drawing, the reference numeral 1 denotes a long stud or bolt having a rounded outer end or head 2 provided with an annular groove 3. At the inner end of the stud or bolt is a peripheral flange 4 by sectional view of .which the bolt may be connected to a curtain 5, automobile body or the like.
lt may be attached to the curtain 5 by a securing member 6 having prongs 7 extending through the curtain 5 and inbent or clenched on the flange 4 to secure it against the curtain d. y y j holding the overlapping edges y 3' vdenotes a piece oi material, for instance, a curtain, having an opening 9 through which the stud 1 is adapted to extend. Surrounding the opening 9 is a grommet composed ot' a front plate 10 and a bac-k plate 11, said iront plate having prongs 12 extending through the piece of material 3 and inbent ory clenched on the back platey 11. The front and back plates have openings 13 registering with the opening 9 so that the stud 1 may extend through the grommet.
14 denotes another piece of material, similar toi-.the piece of material 8,and this piece ott material is sandwiched between a back plate 15 and a holding member 16, said piece of material.l the back plate 15 and the holdingmember 16 having registering openings, generally designated 17, so that the stud 1 may extend therethrough. The holding member 16 has a series of prongs 18 extending through the piece of material 14 and inbent or clenched on the back plate 17. The back plate 17 and holding member 16 cooperate in forming somewhat ofl a grommet for the piece of material 14.
Un the holding member 16 are opposed retaining members 19 which, as shown in Figs. 1 to 4 inclusive are in the form of rivets or pins having heads. rlheretaining members 19 extend through opposed segment shaped slots 20 in a rotatable member 21 and said rotatable member has opposed nger pieces 22 preferably formed byv pressing out portions of said rotatable member.. The rotatable member has an eccentrically disposed opening 23 providing clearance for the head 2 of the stud 1 when. the rotatable member 21 is in an open position, as shown in Fig. 1, and after the pieces of material are placed together or inproximity to each other, as sho-wn in Fig. 2, the member 21 may be partially rotated to shift the opening 23 out ot alignment with the openings 17 thereby causing a marginal edge or wall of the opening 23 to engage in the annular groove 3 of the stud 1, as best shown in Figs. 3 and 4. Rotation of the member 21 is limited by the retaining members 19 and the end walls of the slots 20 define the open and closedpositions of the rotatable member 21. lt is the eccentric relation of the opening 23 relative to the peripheral edges of the rotatable member 21 that permits ot said rotatable member engaging in the stud groeve 3 Wl'ien'partially rotated in one .direction, and this locking principle is embodied yin Figs. 7 and 8, but other retaining members 24. are employed for retaining the rotatable member 2l on the holding member 16. rlvhe retaining members 24. are in the form of lugs cut and stamped from the holding member 16 tofextend through the slots 2O ot the rotatable member and on to said rotatable member, it being understood that the llugs are bentl after the rotatable member is placed on the holding member. `ln either form of. fastener the holding member may have opposed upstruck portions or teats 25 and the rotatable members, adjacent the finger pieces 22, may have upstruclr or 'raised portions 26 to snap into engagement with the teats 25 and thus prevent accidental shifting of the 'rotatable members. f f
What I claim is l. ln a fastener, vthe combination of a stud, a holding member having a concentric opening to receive the stud, a rotatable member on'said holding member' having an opening eccentrically disposed relative to the concentric opening of said'holding member and adapted to be shifted into regis?` tration with the holding member opening to yreceive said stud and permit ,.offsaid rotatable member engaging. in said stud When partially rotated to placev the rotatable mem-` ber opening in eccentric relation to .the holding member opening, and retaining members on said holding member extending through said rotatable member and retaining said rotatable member on said holding memberY to -limit the rotation of said rotatabley member.
2. A `fastener comprising a holding member, a rotatable member, said members being l thereof in eccentric relation to the opening. t of the holding member whereby the shifted rotatable member mayholdthe stud in both A,
