DETACHABLE BUTTON Filed July 19, 1939 INVENTOR. 5 2 1500025 FoLLAK ATTORNEY.

'2 Claims.

This invention relates to detachable buttons, and has for its objects specific improvements in the construction of such buttons whereby a simple, durable, easily applied or detached button structure is had and. which is cheap to manufacture. Other advantages and features of the invention will appear in the following description and accompanying drawing.

In the drawing:

Figure 1 is a greatly enlarged edge view of a button with a hollow retaining washer of my improved construction secured to the bail or eyelet of the button, the washer being shown in cross section.

Figure 2 shows in perspective a somewhat less enlarged perspective view of the hollow washer as seen from the back.

Figure 3 is a View of the hollow washer as per Figure 2 but with the rear cover plate omitted to show the special spring bolt and construction within.

Before describing the invention in detail it may be stated that the principal feature consists of a special hollow washer slotted on one face to receive the metal eyelet or bail of an ordinary button such as are generally used on heavy coats, and uniforms, and within which washer is a specially formed spring bolt which may be projected through the eye of the bail, and which bolt is formed with an operating end projecting out of a peripheral slot in the washer.

In the drawing l is a button of any type of construction or material. 2 is the eyelet or bail of the button (usually of metal or wire) which projects from the back of the button, and by means of which it is secured to the garment, generally as by sewing in place.

3 is my hollow washer and which comprises a front wall 4 slotted centrally as at 5 to receive the button eyelet, and formed with a curled over edge or rim 6, while 1 is a rear plate or closure disk which covers the open side of the saucerlike front wall 4 and is finally spun or crimped over its edge as indicated at 8 to lock the assembly firmly together.

In the center of the closure disk 1 is a bulge 9 which forms within the washer a centering well or depression IE! to center the button eyelet when inserted through the slot 5 so that it will be in correct position to receive the locking bolt II.

The bolt H is preferably formed of one piece of spring wire l2 bent to the shape shown in Figure 3 and with one end l2 crimped or clamped within a short section 6' of rim 6 which is curled inwardly about the wire (as best indicated in Figure 1) by a press operation. The extreme end 52" of the wire projects beyond the clamping section 6 and is bent slightly out of line as indicated, so as to resist displacement.

The general form of the entire spring wire may be said to be of a rounding W shape with the two central legs shorter and arranged close together .to form the bolt or tongue II, the wire bights adjacent the tongue being spaced to provide plenty of clearance at the points x, (B, so as not to interfere with the button eyelet when the tongue or bolt II" is projected through the eyelet. The free end of the wire is extended substantially in a radial direction from the center of the washer through a slot l3 formed in rim 6 and preferably provided on its outer end with a small ring M for pushing with the finger to move the wire along the slot in direction of the arrow to free the bolt from the button eyelet, after first moving the ring i l slightly in a direction to free it from a locking notch l5 formed at the end of the slot.

Closure disk 7 is notched out at it for a distance corresponding to slot i3.

The general W form. of the spring bolt gives the relatively great movement required in so small a space as is formed within the hollow washer, yet insures the movement of the bolt or tongue I I being sufficient to withdraw the bolt completely beyond the edge of slot 5 for release of the button, and to project sufficiently beyond the opposite side of the slot when engaging the button eyelet. However, the form of the spring bolt may be modified within the scope of the invention and appended claims.

The spring is biased to normally hold the button locked in place.

Having thus described my invention what I claim is:

1. A detachable securing member for a button having a projecting attaching eyelet, said member comprising, a hollow washer slotted to receive said eyelet, and a spring wire secured at one end within said hollow washer and projecting at the other end from a marginal slot in said washer, said spring wire formed with a bolt tongue intermediate its ends arranged to engage through said eyelet when in position in said washer, said spring wire being biased to eyelet engaging position, and said marginal slot formed with a locking notch for the spring wire when the bolt tongue is in engaging position.

2. A detachable securing member for a button having a projecting attaching eyelet, said member comprising, a hollow washer slotted to of said W being close together to form' a bolt receive said eyelet, and. a spring wire bent sub tongue intermediate its ends arranged :to prostantially in the form of a W with one of its exject entirely through the hole in said eyelet when treme ends secured within said hollow washer in position in said washer, said spring wire being and projecting operatively at the other end from 5 biased to eyelet engaging position.

a. marginal slot in said washer, the center arms S THEODORE POLLAK.
