In sewing a fastener member to a piece of cloth or other fabric, the thread will be passed through one opening 4, through the fabric and up through another of the openings at, as will be well understood, and as is illustrated in Fig.
The socket member or female member F is of the usual type and it, also, is preferably drawn, stamped Or spun from sheet material. It comprises a central socket 10 depressed in flange 12, from the outer face thereof, which is the face exposed when the said member is sewed to a fabric and the outer edge of which is spun or curled into a ridge 13 on that side of the base which is opposite that in which the depression of the socket enters, or on the inner face which lies against the fabric.
A spring 11 operates through opposite slits in the side walls of the member 10, which forms the socket, and those parts of the spring that pass through said slits into the socket are adapted to engage the stud 1 and hold it frictionally or elastically within said socket when the two members are united.
The spring 11 is mounted in the usual way known in the art. In the said member F are thread openings , similar to the openings 4 in the member M, and through these openings threads may be passed in sewing the member F to a fabric in the same manner as in sewing the member M to a fabric. The relation of the members M and F, when in engagement, is such that the rim 3 on the member M prevents the member F from contacting with the threads 5 on either of said members.
There can therefore be no chafing or cutting of said threads by the contact of the members. Nail-making machine.. Compound pulley.. Chain drive.. Hydraulic press.. Screw-cutting lathe.. Yale lock.. Screw propeller.. Standardized screw system.. Phillips screw..

Who would have imagined that our mastery in hardened steel was first used for "pipe clips" on the display racks of the French tobacconists? In , the company will once again demonstrate its ability to adapt and launch the first hardened steel clips for the automobile industry, whose mechanical properties spring effect respond to the car manufacturers' concerns: speeding up the assembly of shell components.
