BUTTON.

1 Application filed. July 29,

T 0 all whom it may concern.

Be it known that I, ERNST KLEINMANN, a citizen of the German Republic, residing at Berlin, Germany, and State of Prussia, have invented certain new and useful Improvements in Buttons, of which the following is aspecification.

This invention relates to buttons with an outside coating or covering of any suitable kind of material such as cloth or the like which completely inclosesthe whole top portion of the button. Durable buttons of this kind could hitherto only be made with the aid of machinery. Therefore it was not possible for dressmakers, housewives, etc., to make such buttons themselves. 1 In distinction from those known typeset buttons the present invention enables the button with its covering to be made by anybody without the aid of tools. To render this possible the button is composed of two spring'parts adapted to engage with one another and between which the material forming the covering is clasped or clipped.

Some constructional forms of the invention are shown in the drawing in which Fig. 1 is a section of a finished button,

Fig. 2 is a plan view of the bottom or base portion of the button,

Fig. 3 is a section of a button with a spring clipping plate, v

Fig. 4 is a plan view of the base portion of a button provided with serrations of a special kind,

Fig. 5 is a modification of Fig. 3 and Fig. 6 is a modification of Fig. 5.

As shown in Figs. 1 and 2 the upper half of the button is covered with cloth 0. The base portion 7) of the button is made of two parts and has an annular shoulder b and an upper indented portion which, when it is pushed into the upper half, has its outer edge turned downward so as to turn the cloth back over a ledge at the bottom of the upper part a as shown in Fig. 1. The ring of teeth on the base portion firmly holds the cloth 0 clipped in between the base 5 and the upper part a.

In the modification shown in Fig. 3 the base portion 5 is provided with a special spring plate (I which is pressed into the top Specification of Letters Patent. Patentg1IAug, 22,

oortion a and then causes the cloth coverillustrated. This arrangement ensures that cloth coverings of very different thicknesses 'will always be seized by at leastsome of the teeth the longest teeth taking effect if the cloth is very thin and shortest if the stuff is very thick. In the l long teeth would be bent back so far that their points would not afterwards enter the cloth.

In the modification shown in Fig. 5 the atter case the base portion 5 equipped with a spring plate 0? with a ring of downwardly extend ino flaring teeth which are not uniform but of diil'erent lengths for the reason mentioned above. v

A special type of the kind of button shown in Fig. 5 is illustrated in Fig. 6 in which the base portion Z) is formed with steps b, so that it has a conical shape and may be pressed more easily into the top portion. The steps 2), also enable the teeth 0Z (Z, of the spring plate (Z to move out of the way. "i

In order to avoid the danger of the thread passed through the transverse hole of the base portion 5, and by which the button is sewed on, from being damaged by the button beingrotated. the lower part of the base portion, i. e. the part that receives the thread, may be adapted to rotate freely relatively to the part oi? the base portion that grips the cloth covering 0 of the upper portion a of the button. This may be accomplished'by adapting the thread-receiving part .7), of Fig. 1 to loosely embrace the lower flange-shaped part of the serrated gripping or clipping member 7), or by adapting the spring plate d of Figs. 3, 4C, 5, 6 to revolve freely on the rivet or neck I), by which it is attached to the'lower part of the base portion.
