CLOSING DEVICE FOR COLLAR BUTTONS Filed May 27. 1930 Patented Sept. 27, 1932 UNITED STATES KURT KLEIBER, or sennnnne, GERMANY V CLOSING DEVICE FOR, COLLAR BUTTONS Application filed May 27, 1930, Serial No. 456,156, and in Germany May 29, 1929.

The present invention has for its object a closing device for collars i. e. for collar buttons comprising a circular head intended to embrace the top of the collar button, and provided with a bent lever, the characteristic feature being that the hollow circular cup is provided on two opposite sides with an overlapping incurved border and moreover on the inner circumference, symmetrically to the 1 border opposite to the said lever with a hollow for lodging a flat spring, the distance of the two borders being interior to the outer diameter of the button which can be introduced obliquely, but is notwithstanding held in its exact position by said spring in combination with the overlapping borders.

On the accompanying drawing:

Fig. 1 shows the inner side of the hollow head of the device,

Fig. 2 is a cross section according to the line 1-1 of the Fig. 1,

Figs. 3 and 4 show the function of the closing device,

Figs. 5, 6 and 7 are different views of the instrument.

The closing device comprises a circular cup-like head a provided with a bent lever or handle 6. Figs. 1 and 2 show the head in an enlarged scale. This head has for its ob ject to grasp the button head properly, said button not shown in the drawing, and to introduce it into the openings of the collar. This hollow part a corresponds to theouter form or" the collar button and is provided on two opposite sides with projecting borders a and d. On the side, whereon is situated the border (Z, is provided a cavity a for lodging a flat spring The length of this spring is somewhat superior to the rectilineal distance between the abutments g, h (Fig. The device is so manipulated as to cause the head of the collar button to enter the cup obliquely through its rear side and with its upper edge bearing against the spring f which yields to permit the lower edge of the head to slip into the cup over the lower flange 0, the head of the collar button being then engaged by the flanges b and c, as will be understood, and the spring remaining in compressed condition. This prevents casual detachment of the desuiiicient to exercise by hand a short pull on the handle 6, said pull being directed in an oblique direction in view of the-special form ofthe shutting device. Thespring-is therefore again compressed and the'iiange of the button head passes from the flange 0 of the cup. As soon as the device is somewhat loosened from the hand of the operator the bent spring pushes the button entirely out from its lodging. V,

The handle I) of nearly elliptical'cross sec tion is directed tangentially and passes through an acute angle (Fig. 7 to the horizontal plan of the button, forming thus a spiral like body. The middle part of the handle is formed in such away that in each position of the collar on this middle part,

the resultant of the eiiorts acting on the opening ofthe collar, i. e. the end of the collar, is directed to the center, and to the-button, so that the said end of the collar is moved towards the button in turning the shutting device by hand in the direction of the arrows. In Figs. 3 and 4 two different positions of the collar are represented during the shutting or closing action. Fig. 3 shows moreover the diagram of the efforts, wherein the arrow ondesignates the traction effort of the collar and n the effort normally exerted by the lever on the collar end during the rotation of the closing lever, the resultant being indicated by the arrow 0 directed on the center of the button. It will be observed that the curvature of the arm I) is greatest at the point where it leaves the head a. and that the outer end y which is substantially at right angles tothe plane of the head and the inner portion of the arm is somewhat pointed to facilitate its insertion through the button hole of the loose end of the collar and for enlarging said button hole to facilitate the easy passage of the head therethrough, this being effected by turning the arm clockwise, as will be understood.

The cup of the instrument is fixed in the above described manner on the collar button. The outer end :1 is then introduced from the inner side into the opening of the right end of the collar. The right hand of the manipulator grasps the top end y and turns the device in the clockwise direction like a crank, so that the end of the collar is, owing to the spiral form of the instrument, progressively moved towards the cup a and slides then over the latter on the button proper. The top end g is then introduced in the opening of the opposite collar end and the same movements are effected in I a similar manner.

Owing to this movement the left free end of the collar is introduced from below into the other end (Fig. 4). g

It must be mentioned that the closing device shows only flat walls and no projecting parts or edges which might damage the collar.

I claim:

1. A collar buttoning device comprising a cup shaped head arranged to engage and receive the head of a collar button and provided with a spring to bear on one side of the flange of a button head and an arm extending from one side of said cup shaped head and adapted to pass through a button hole in the loose end of a collar.

2. A device as claimed in claim 1, in which the arm is substantially helical in form.

8. A device as claimed in claim 1, in which the inner portion of the arm is coplanar with the cup shaped head and the outer end portion of the arm is bent outwardly and arranged substantially at right angles to the common plane of the head and inner portion of the arm.

In testimony whereof I have hereunto set my hand this 15th day of May, A. D. 1930.

KURT KLEIBER.
