SEPARABLE CUFF BUTTON.

Application filedJuly 8, 1925.

ments in separable Guilt Buttons, of which the following is a specification.

This invention relates to a separable cufi' button and one object of the invention is to provide a cuff button or" this type in which the two sections of the button may be very securely held together and easily disconnected when desired.

Another object of the invention is to provide a cuft' button in which one section is hollow and the other section provided with a "headed stein adapted to fit into the hollow section, improved gripping jaws being mounted in the hollow section for gripping engagen'ient with the headed stem of the other section. and means being provided in the head of the hollow section to move the jaws to a releasing position when so desired.

Another object of the invention is to so construct the jaws that they may be easily assembled when the hollow button sectihn is manufactured and retained in the shank of this section by a cap secure upon a head at the inner end of the hollow shank.

Another object of the invention is to provide an improved type of spring which is mounted in the outer head of the hollow section and extends radially of the head for operative engagement with the free ends of the gripping jaws.

Another object of the invention is to provide a button in which the gripping jaws, spring for the jaws and means for moving the jaws to a releasing position will be housed almost entirely within the hollow button section where they will be protected and prevented from being damaged it the button section is dropped or roughly handled.

This invention is. illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of the improved button with the two sections separated; 1

locked together until the releasing means carried by the button 1 is actuated to cause the stenr3 of the button 2 to be released and permit of the sections being drawn apart.

The section 1 is hollow and includes an outer head 4:, an inner head 5 and a shank or neck 6 which connects the inner head with the outer head. The shank 6 is preferably formed integral with the inner head 5 and has its outer end portion reduced so that the reduced outer end portion may be passed through an opening formed in the inner disk 7 of the outer head 4 and rolled into tight clinching engagement with the disk 7 as shown in Fig. 2. The outer disk or cap 8 of the head 4 has its peripheraliportion rolled into clinching engagement with the periphery of the inner disk 7 and may have its outer face ornamented or left plain. It will be obvious that if. desired the outer disk or cap 8 may be formed of gold or other precious metal, whereas the inner disk 7 and shank and inner head may be of a cheaper material.

The jaws 9 which are disposed in the hollow shank 6 are formed of strong metal and their outer portions are substantially semi-circular in cross section, as shown at 9, so that, when in place, they may fit snugly within the shank and permit the stem 3 to be easily forced inwardly between them. Each jaw is of a length to extend from the outer face of the inner head 5 to a point within the hollow outer head i and has its tree inner end portion provided with an outwardly extending longitudinally curved lip or flange 10. Side arms 11 which serve as pivot pins for the jaws extend transversely from opposite sides thereof, as shown in Fig. 5, and fit into recesses 12 formed in the head 5 so that the jaws are pivotally mounted at their outer ends and may have their inner end portions moved towards and away from each other into and out of a gripping position- It will, of course, be obvious that normally the inner free end portions ofthe aws are spaced from the walls of the shank 6 a sufi'icient distance to permit them to be moved away from each other when it is desired to release the stem 3. Th curved portions 9 ot' the jaws taper from their outer ends towards their inner ends, as shown in Figs. 2 and 7, and thereby provide cam surfaces so that, when the stem 3 is thrust between the jaws, its shouldered 'head 1.3 may force the jaws apart against the action of the spring 14 as the head moves inwardly into position where it may fit into the openings or sockets latt'ormed in the jaws at the forward ends of the tapered portions 9. The spring 1i is formed of a strand of resilient wire which is substantially U-shaped, as shown in Fig. 3, and has its bridge portion secured beneath a tongue 16 cut from the peripheral portion of the disk 7 and its arms 17 extended substantially radially of the disk and engaged with the free end portions of the jaws beneath the lips or flanges 10. It should be noted that the arms 17 ot the spring are bent, as shown in Fig. 3, so that the free ends of the arms will be normally very close to each other, and, therefore, wnen sprung into position for engaging the jaws will provide a very good spring action and serve to very firmly hold the jaws in gripping engagement with the head 13 of the stern 3. In order to re move the stem from between the jawswhen it is desired to-separate the button sections, it is necessary to movethe free end portions of the jaws away from each-other against the action of the spring. In order to do so, there has been provided a plunger 18 which is carried by the hollow outer head a and includes a tapered wedge-forming head 19 disposed within the hollow head t and astem 20 which projects outwardly through an opening 21 formed centrally of the outer cap 8. The inner end of th wedge-shaped head 19 fits between the flared free end portions 10 of the jaws, and it will be obvious that, when the plunger is forced inwardly by pressure applied to the outer 22 is provided upon the outer face of the inner head 5 and has its peripheral portion rolled into clinching engagement with the head 5, as shown in Fig. 2, so that this cap plate is securely held in place. The open ing 23 which is formed centrally in the plate 22 is of sufiicient size to permit the stem and its head 13 to be moved into and out of the hollow shank through the cap but the cap plate extends in overlying relation to the pivot arms or pins 11 and outer ends of the jaws so that the jaws will be prevented from slipping outwardly and becoming dislodged.

lVhen the button is in use, the section 1 is inserted in the buttonhole at one side of a cult with the cult disposed about the shank 6 and between the heads 4 and 5. The section 2 is inserted in the buttonhole at the other side of the cufl with the cult disposed about its shank 24 and between its inner and

outer heads

25 and 26. The stem 3 extends from the inner head 25 of the section 2 and by applying pressure to the outer heads at and 26, the stem may be forced inwardly between the jaws. As the stem passes inwardly between the jaws, it will cause the jaws to be moved apart until the head 13 reaches the sockets 15. The spring 1 1 will then move the jaws towards each other and o Jposed portions of the head 13 will be firmly seated in the sockets 15. c The two button sections will, therefore, be very securely held together and cannot readily work loose. When it is desired to release the button sections, it is sin iply necessary to grasp the head 4 at opposite sides ot' its periphery and by applying pressure to the outer end of the stem 20 force the plunger 18 inwardly so that the head 19 will be moved inwardly between the flared free ends of the jaws and force the jaws apart a suitieientdistance to release the head 13 and permit the stem 3 to be withdrawn. There has, therefore, been provided a separable cu'ti button which will be neat in its appearance and so constructed that the two sections may be securely held together but readily released when so desired.
