To @ZZ whom zt may concern.'

Be it known that I, FRANCIS F. HEILBORN, a subject of the Emperor of Germany, anda resident of Plainville, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Buttons, of which the following is a specification.

My invention relates to that class of bu ttons in which the shoe is hinged to the post; and it consists in the improved construction and arrangement of the parts, as hereinafterfully set forth.

Figure 1 represents an elevation of the button with the arms of the shoe opened to their locking position. Fig. 2 represents the same with the arms of the shoe closed to their proper position for insertion into the buttonhole. Fig. 3 represents an under side View ofthe button with the shoe in the position Fig. 4 represents a section taken in the line @c a: of Fig. 3, with the shoe closed. as in Fig. 2. Fig. 5 represents a section taken in the line y y of Fig. 3, with the shoe closed, as in Fig. 2. Fig. 6 shows the form of the sheet-metal blanks for making the shoe.

In the accompanying drawings, A is the head of the button; B, the hollow post, which is made in rectangular form and attached to the head Aat the sides a a, and provided with an opening b at the sides c c to receive the flat spring d, the said spring being arranged to act against the sliding piece e, which rests upon the spring and looselyts the hollow of the post B and is provided at its upper end with a flat bearing-tace, which serves to hold the two loop-arms O and C of the shoe in' their proper set position. The loop-arms C and C are each first ont from sheet metal in the form shown in Fig. 6, and are then bent to the form shown in Fig. 3, the loop C being made small enough to pass Within the loop C', as shown in Fig. 4. The arms C and C are each provided with angular en dsf, through the perforations g in which the pivot h is made to pass, and the fiat bearing-face ot the sliding piece e, which will be pressed by the flat spring d iirmly against the straight edges 1I t' andy' of the loops, according to the position in which they are placed, Will serve to hold them properly7 in position.

I claim as my invention- In a button', the combination, withthe head A and the attached hollow post B, provided with the openings b (Lof the spring CZ, sliding piece e, and the unequal loops C C', pivoted to the post B, one Within the other, and provided with the angularends f, adapted to bear against the end of the piece e, substantially as described.
