CUFF BUTTON.

Application filed May 12, 1922. Serial No. 560,428.

T 0 all whom it may concern.

Be it known that I, BERNARD GoLnsTEiN, a subject of the King of Great Britain, and resident of the city of Toronto, county of York Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Cuff Buttons, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of the invention are, to avoid the inconvenience and unpleasant conditions caused by the accidental separatin of the button members and to provide a liutton which will lock securely when in a closed position but which may be separated very easily.

A further object is to devise a two piecebutton which may be used with stiff cuifs without undue restriction and injury to the cuff.

A still further object is to devise a structure which may be easily manufactured and assembled.

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby the connecting shank is locked in the socket portions of the buttons by spring members adapted to enter between the inner wall of the socket andreduced neck portions of the shank and whereby one of said locking members may be withdrawn from the locking position to release the shank.

In the drawings, Figure 1 is an enlarged sectional View of a button constructed according to this invention showing the members in the locked position.

Figure 2 is an enlarged sectional view showing the button members separated.

Figure 3 is an enlarged perspectiile detail of the spring locking member separated from the button.

Figure t is an enlarged elevational View of a button provided with'a bent shank.

Figure 5 is a view similar to Figure 4 showing a flexible shank.

The separable button type of cufl button has been brought into considerable use but with the types having a snap spring grip the springs do not hold satisfactorily and the buttons come apart accidentally and very often cause considerable inconvenience and it is the purpose of this invention to definitely and automatically lock the two members together so that they cannot be pulled apart by the application of force but may be very easily separated by properly releasing the same.

The button members are here shown each formed with a conveXed crown plate 1 and spun body portion 2 converging from the crown plate and forming the narrow throat 3 and then diverging to form a flaring mouth 4:.

One of the buttons is provided with a convexed spring plate 5 loosely heldbetween the body and the crown plate. The locking member 6. which is of sheet metal, is formed with a plurality of convergent fingers 7 curved longitudinally to conform to the converging contour of the body 2 and having the tips curved transversely to conform to the cross sectional curvature of the body adjacent to the throat 3. This member is held into the throat by the spring plate 5.

i A locking member 8 similar to the member 6 is arranged in the other button and attached to this locking member is a shank 9 which extends through the crown plate anal has a small knob 10 secured on its outer en An arched spring 11 is arranged upon the shank 9 and the ends thereof bear against the crown plate and hold the locking member into the throat of the button but by pulling upon the knob 10 this locking member may be withdrawn from the throat of the button.

The shank 12 is formed with the head ends 13 each having a convergingneck portion 14. These head ends are adapted to enter into ihe throat openings 3 of the button memers.

The maximum diameter of the heads is slightly smaller than the throat openings 3 so that they will enter freely and the neck portions conform in contour to the shape of the inner surfaces of the fingers of the locking members.

he fingers of the locking members are adapted to spread apart to receive the head of the shank 12 and then fit snugly around the neck ortion thereof and between said neck portion and the interior of the throat 3.

The shank is assembled as part of the button containing the spring plate 5 by being pushed into the'throat. The head end pushes the locking member inward flexing the plate 5, and spreading the fingers 7 itslips in between them and the spring plate 5 pushes the locking member outwardly so that the locked in the button.

In the form shown in Figure 4 the shank 15 is curved to hold the buttons at an angle the one to the other and conforming to the natural angle of a stifi cuff. The cuff is not drawn in too close as is the case with the ordinary button. In Figure 5 the shank 16 is shown with a link or swivel joint to allow the buttons to assume the angle of the cuff.

In the use of this button when the members are separated the arched spring 11 holds the locking member 8 to its outward position so that its spring fingers engage the throat of the tapered body portion 2. When the buttons are pressed together the head of the stud engages the ends of the fingers. The locking member is pushed inwardly against the tension of the spring 11, as shown in Figure 2, until the pressure overcomes the inward tension of the spring fingers, said fingers then spread apart and allow the head of the stud to enter further. As the head moves inwardly assuming the position shown in Figure 1 the locking fingers slip over the head and enter between it and the wall of the body portion. When in this posit-ion the fingers engage the body portion on the outer side and they thus form a liner within the neck of a smaller diameter than the head which thus effectively prevents the removal of the head from the body and the two buttons are locked securely together and will tear to pieces beforathey will separate.

When it is desired to separate the buttons the knob 10 is pulled outwardly thus drawing the fingers of the locking member inwardly from their locking position surrounding the head of the shank and the shank is then free to be withdrawn.

It will be seen that a button such as described will hold very securely and will be absolutely dependable and is capable of bein very easily and quickly disengaged.

Vhat I claim as my invention is 1. A cufl button, comprising, a pair of socket members each havin a convergent throat, a shank having hea ends and reduced neck portions, a locking member arranged in one socket member and adapted'to encircle the neck of the shank and permanently prevent withdrawal of the head, a

locking member arranged in the other socket adapted to encircle the neck of the shank to hold it securely from withdrawal, and means arranged in the latter socket member for withdrawing the locking member to release the shank and means for effecting the withdrawal of one of the locking members.

2. A cufl' button, comprising, a pair of socket members each having a convergent throat, a shank having reduced neck portions, a locking member arranged in each socket member and having a plurality of spring fingers adapted to surround the head and embrace the neck of the shank within the throat of the socket member, and spring means adapted to move said locking member into the throat on the insertion of the head thereinto. v

3. A cufl' button, comprising, a pair of socket members each having a convergent throat, a slidable member extending through a, hole in the crown of one socket member and having a knob on its outer end, a member having a plurality of curved spring fingers secured at the inner end of said slidable member, a shank irremovably secured in the other socket member and having a head adapted to be engaged by said spring fingers and locked in place, and a spring member arranged to hold said slidable member inwardly.

4. In a cuff button, a Socket member having a convergent throat, alocking member arranged within said button and having a plurality of spring fingers extendinginto the throat, a spring member arranged to hold the fingers of said locking member in the throat, and a shank member provided with a head adapted to enter the throat and a neck to receive the spring fingers of the locking member.
