SPECIFICATION forming part of Letters Patent No. 553,938, dated February 4, 1896.
A pli ti fil d September 19, 1395. Serial No. 562,983- (No model.)
To all whmn it may concern:
Be it known that I, CARL FR. REICHELT, a citizen of the Kingdom of Prussia, and a resident of Berlin, in the Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Self-Fastening Buttons, of which the following is a specification.
This invention relates to improved buttons and button-fasteners comprising a self-fastening button wherein a headed fastening device is provided with two or more entering prongs, and a solid-faced button having upon its inner side a'plate through which the entering prongs pass and to which they may be secured.
The object of my invention is to provide an improved button and fastener which may be easily attached by simply pressing the fastener upon the button, and which will be securely retained thereon with an elastic pressure to avoid tearing out the material when extra strain is brought upon it, and which will provide a longbearing and a plurality of obstructing instrumentalities to connect the fastener with the button.
The improvement consists in certain constructions and combinations of parts hereinafter particularly described with reference to the accompanying drawings, in which- Figure 1 is an enlarged sectional elevation of my improved button; Fig. 2, a plan view of the shank side of the fastener-head; Fig. 3, a plan view of the cone-nut to be secured inside of the neck of the button, and Fig. 4 a side elevation of the inside shank-plate and its shank and a needle secured in the slot of said shank to more readily pass the shank through the fabric.
The button is formed of an outer case or shell d, having an inwardly-turned rim-flange (1 formed thereon, within which is fitted the outwardly-dished disk 0 of an inside plate 0. The central portion of plate 0 is conical and projects inwardly to form the neck 0 of the button. A cone-nut b is fitted upon the inside of the neck a of the button to conform to its conical interior, and is bored centrally to provide a series of inwardly-protruding angular rings or serrations to engage with similar serrations upon the exterior of the shank a, fastened therein and formed integral with a head or inside shank-plate a which, when secured to the shell button provides a simple and inexpensive self-fastening button.
In order that the fastener may be more easily inserted and securely retained, the fastener-shank a has upon its outer end a conoidal-shaped head a, providing an abrupt shoulder a which head passes through a central aperture, a thin spring-plate f, and thus provides additional means for connecting the button to the fastening-shank.
The shank a is split from its head a to within a short distance of the inside shankplate a and is preferably split twice crosswise, as shown clearly in Fig. 2, thus providing four prongs a a 665 a, each of which is so arranged and disposed that it will pass through the cone-nut b, and their separate head-sections a will each enter or pass through the spring-plate f and engage therewith, the numerous serrations and shoulders upon the several prongs serving to each yield more readily against a direct inward pressure, while the said serrations will each hold independently and more tenaciously to its interlocking serration upon the cone-nut of the button, thus securing a firmer and more secure union between the button and the garment.
The spring-plate f performs an important double function. It not only holds the end of the shank directly inside the head a independently of the cone-nut b, but it acts with a spring-pressure upon the shank, inside shankplate, and cone-nut to draw the neck 0 of the button with a slightly-yielding pressure and thus compensate for varying thicknesses and elasticity of texture of the fabric.
In order to attach the shank and its inside plate to the button with the fabric between them, the needle g (shown in Fig. 4) isfirst placed in the cross-slots of the shank a, and both are pushed through the fabric at the point where the button is to be attached. The needle is then removed and the button pressed down upon the shank, the central hole of the conical nut receiving the shank, and the separate inwardly-yielding prongs being free to push themselves past the serrations of the cone 1) and in the central opening of the spring-plate f, thereby pressing the cone toward the plate f. The diameter of the bore of the cone and the hole in plate f being less than that of the head a, a compression of the said slitted head a and of the four shanks a a a a will take place; but the shanks will, if the head a has passed the hole of the plate f, spread again by their elasticity, and the shoulders of the said head a, will engage with the plate f, While the serrations of the shank will engage with those of the cone and thus form a double fastening, the spring-plate giving the parts When united a limited degree of elasticity.
I claim as my invention and desire to secure by Letters Patent- A button and its fastening consisting of two button-plates secured together at their CARL FR. REICHELT. Witnesses:
