SEPARABLE BUTTON.

To all whom it may concern Be it known that I, FRANCIS STASHKO, a subject of the King. of Hungary, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification The present invention relates to improvements in separable buttons, and has for one of its objects to provide a simple, inexpensive and durable device, the parts of which can be easily made and assembled, whereby the cost of manufacture of the article is reduced to a minimum, and in which the separable parts may be easily manipulated. and securely locked, when assembled, against accidental separation.

l-Vith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical section taken through a button constructed in accordance with the present invention; Fig. 2 is a bottom plan view on an enlarged scale of its head; Fig. 3 is a section taken on line 3-3 of Fig. 2; Fig. 4 is a sectional view of the base and the stud of the button; Fig. 5 is a bottom plan view of the element shown in F 1; Fig. 6 is a perspective view of a cletail of construction; and Fig, 7 is an elevation of a further element of the button.

In the drawings, the numeral 11 indicates the head of the button, comprising a suitably shaped hollow body 12, to the back plate 13 of which is centrally attached a shank 14:, which is provided at its lower end with a base 15. This base has upon its outer face sharp teeth or edges 16; which are adapted to enter the fabric to which the button is to be attached. 1n the shank 14L is formed a cylindrical bore 17, extending Specification of Letters Patent.

through the said shank and being provided with a longitudinal groove 18. The inner end 19 of the shank projects into the hollow body12 ofthe head. The upper edge of the shank is provided with a double incline,

posed a stud 23, the upper end of which is provided with a lug 24:. The diameter of the stud is slightly smaller than the diameter of the bore 17 in the shank, the groove 18 being wide enough to receive the lug 2 1. That end of the stud which projects beyond the outer face of the base 22 is squared, as shown at 25, a leaf spring 26 being drawn over the squared end and held on the said base by forming a flange 27 on the said squared end. When the two elements of the button are taken apart, there is a space left between the spring and the base 22, the stud 23 being adapted to be shifted in the direction of its longitudinal axis.

The operation of the device is as follows: The head of the button is placed in proper position upon the fabric, denoted in the drawings by the numeral 28, its teeth 16 being lowered into the fabric to keep the said head against rotation. The stud 23 is then inserted into the bore 17 of the head with its lug 24 in the groove 18, and forced toward the head 11 as far as the fabric will permit and until its lug registers with one of the recesses 18. A turn is then given to the stud, whereby its lug is brought out of register with the groove 18 and seated in a recess 18, thereby engaging the corresponding ratchet tooth-like projection 18". A pin 30 is then inserted into the groove through a hole in the base and spring, such pin preventing an angular turn of the stud relative to the head of the button and thus a disengagement of said two parts. It is to be observed that, inasmuch as a row of projections 18 is provided in the bore of the shank, the button is adapted for use upon fabrics of varying thicknesses. If the button is to be attached to a very thin fabric,

for instance silk, the stud is fully inserted into the head of the button, whereby its lug will be disposed upon the incline 20. lVhen now the stud 23 is turned about one-half of a turn to the left, the lug travels up on the incline until it abuts against the sto 21. By this operation, the spring 26 is rmly pressed against the base 22, and thereby draws the lug 24 against the inner face of the shank, thus preventing va relative motion between the stud and shank. For safety shank projecting into said head and having I I an incline, of a back having a stud adapted 25 to be inserted into said bore, a lug upon the 7 upper end of said stud fitting said groove,

said stud being adapted to be turned when its lug registers with any one of said recesses or when it is fully inserted into said bore, whereby in the latter case its lug travels up on said incline, a pin adapted to be disposed in said groove tovprevent relative rotation of the parts When in coupled positions," and a spring carried by said stud suitby a row of ratchet teeth-like projections is provided, the inner end of said shank projecting into said head and having an incline, of a back having a stud adapted to be ins'ertedinto said bore, a lug upon the upper end of said stud fitting said groove, said stud being adapted to be turned when its lug registers with any one of said recesses or when it is fullyinserted into said bore, whereby in the latter case its lug travels up on said incline, a stop for limiting the upward travel of said lug on said incline, a pin adapted to be disposed in said groove to prevent relative rotation of the parts when in coupled positions, and a spring carried by said stud suited to prevent accidental relative rotation of the parts when said lug has reached the top of said incline.

Signed at New York, in the county of New York, and State of New York, this gtth day of May, A. D. 1914.
