FASTENER.
Application filed June 14, 1924. Serial No. 719,927.
This invention aims to provide an improved stud andsocket' fastener.
In the drawings, which illustrate a pre ferred embodiment of my invention 'Fig. 1 is a front elevation of the preferred form of my invention;
Fig. 2 is'a rear elevation of the stud; Fig. 3 is a section partly in elevation on the line 33 of Fig. 1;
Fig. 4 is a section similarto Fig. 3, but
showing the locking means disengaged from the socket-engaging part of the stud;
Fig. 5 is a front elevation of the preferred form of'socket; and 1 Fig. 6 is a section on the line 6+6 of Fig. 4.
Referring to the drawings and to the preferred form of my invention selected for illustrative purposes, I have shown a stud adapted to be secured to a curtain 7 in any suitable manner, butI prefer, as illustrated, to provide a front plate 9 presenting a plurality of attaching prongs 11, which pass through theicurtain 7 and openings in the base 13 of a resilient socket-engaging member 15. The prongs are then clenched into depressions 17 provided in the base 13 of the stud so as to present a smooth surface at theback of the curtain,as best illustrated in Figs. 2, 3 and 4. By this method of attaching the stud to the curtain, the parts are reduced to a'minimum in number because of the elimination of the usual back plate or clench plate. Thus the cost of manufacture of a fastener of this type is substantially reduced without reducing thedurability and the fabric-gripping qualities of the stud.
The socket-engaging part of the stud is provided with slots 19 which extend to the base 13 of the stud, thereby to permit contraction and expansion of the socket-engaging part when engaging or disengaging a socket. This socket-engaging member 15 is also providedwith an annular depression or neck 21 for engagement with a'socket.
While the stud may be maintained in engagement with a socket by the resiliency'ot the contractible and expansible member 15, I prefer to provide means for locking the head with the socket and means for displacing the locking means to permit contraction of the member 15. The above-mentioned means preferably comprises a pull-button member 25 presenting a shouldered locking part 23 for engagement with the inside surface of the neck 21 and when engaged there- 1 with to prevent contraction ofthe head of the stud, and an enlarged button or knob 29 located outside of the front plate 9. I
The knob 29 may be manually operated to shift the shouldered part- 23 into or out of engagement with the neck 21 as desired.
The shouldered locking part 23 is preferably made separate from the rest of the pullbutton member and riveted thereto after the reduced part of the pull-button member has been entered through the aperture in the front plate 9. Thus the front plate 9 and pull-button member 25 are held in assembled relation to each other as a unit before assembling the stud upon the stud-carrying curtain 7 The preferred form of socket includes an attaching screw 31 having a hexagonal head 35 rigidly secured to the hexagonal body portion 37 of the socket. The preferred method ofsecuring the head of the screw to the body portion of the socket is to provide an enlarged portion 38 at the inner end of the socket body portion 37 into which the head 35 of the attaching screw fits, and in which it is secured by rolling a part of the enlarged portion 38 over the edge of the head of the screw and onto the face thereof.
The socket also includes a front plate 39 which is secured to the flange 41 located at the outer end of the body portion 37, and presents a stud-receivingaperture surrounded by an annular neck-engaging wall 4:2
' preferably curved inwardly from the face of the front plate 39 to provide a smooth bearingsurface for the socket-engaging part 15.
Inside the socket, I have provided a sealing and tool-receiving part 43 also hexagonal in crosssection to fit the body portion 37. This part4?) present a hexagonal depression 15, for reception of a suitable socket-attaching tool, and -is normally urged into aperture-closing position by a spring 47.
The socket may be secured in place upon the body 19 of an automobile by inserting a suitable tool in the depression 45 in the sealing'and tool-receiving part 13 and rotating the tool in a clockwise direction, thus rotat ing the entire socket and screw to draw the body portion37 of the socket into a re cess 51 in the body l9 until the flange at the outer end of the socket is seated against the face of the automobile body 49.
When the socket is attached to the body of the car, that portion of the front plate 39 which is clenched over the flange l1 will be seated against the face of the body of the car, or other object, and will, as illustrated, conceal the recess in the body of the car from view, thus presenting a socket that is substantially flush with the surface of the object to which it is attached.
When engaging the stud with the socket, the locking shoulder part 23 must be out of engagement with the neck of the stud so that the head of the stud may contract and enter the stud-receiving aperture. The neck then engages the peripheral wall 42 of the stud-receiving aperture, thus allowing the head to expand again and thereafter the locking shoulder part 23 may be urged into locking engagement with the neck of the stud by pressing inwardly upon the knob 29 located at the front side of the curtain. \Vhen the stud is locked with the socket, it cannot be separated therefrom by any accidental strain exerted upon the curtain in any direction because of the locking shoulder which prevents contraction of the head of the stud.
Separation of the stud from the socket is effected by pulling upon the knob 29 until the head of the stud is free from the socket or by pulling the knob to disengage the locking shoulder and thereafter exerting a slight pull on the lower edge of the curtain.
While I have shown and described a preferred form of one embodiment of my invention, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.
