,/A/v /VZ'UMAA/A/ Patented Feb. 22, 1949 BUTTON Jan Neumann, Brunn, Czechoslovakia Application March Z0, 1947, Serial No. 735,904 In Germany October 20, 1941 2 claims. 1

The invention relates to buttons for fastening pieces of cloth together and relates more particularly to buttons which may be removably fastened to a piece of cloth or the like.

Desirable features for buttons of this type include simplicity of application to a piece of cloth, resistance against unwanted removal and durability and strength, and these features, within certain limitations, are generally found among buttons of this type now in use.

However, these buttons at present usually do not permitl of easy removal once they are fastened to a piece of cloth, and generally may be removed only at the price of destruction of the button structure itself. f

It is, therefore, one of the principal objects of the invention to provide a button which may easily be removed from its attachment to a piece of cloth and may repeatedly be fastened and removed without damage to the button structure.

Another object is the provision of such a button which will firmly engage a piece of cloth when attached thereto regardless of the thickness of said cloth.

Another object is to provide such a butto which is pleasing in appearance and simple to apply.

A still further object is to provide such a button which may be regulated according to the thickness of the cloth to which itis fastened.

With the above and other objects of the invention in view, the invention consists in the novel methods, construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, certain embodiments of the same being illustrated in the accompanying drawings and described in the specification.

The foregoing and other objects of the invention will be best understood from the following description of exemplifications thereof, reference being had to the accompanying drawings, wherein:

Fig. 1 is an elevational view, partly in section, disclosing a button fastened to a piece of cloth, in accordance with my invention,

Fig. 2 is a plan view of the same, and

Fig. 3 is a longitudinal sectional view of a modified button embodiment.

Referring now particularly to Fig. 1, I provide a. button which broadly consists of two parts, a male and a female part. The male part comprises a shaft 2 which is preferably pointed at one end to permit piercing through a cloth I for inserting said shaft 2 through the pierced hole thereof, said shaft 2 carrying on its other end a flange 3 substantially perpendicular to the longitudinal extension of said shaft 2 and adapted to lie in abutment against one surface of said cloth I when the button is fastened to the cloth.

The female part has a disk-like portion 4 which constitutes the button portion of the entire device. A hollow sleeve 5 is connected to said diskshaped portion 4 about centrally and is preferably integral therewith and projects perpendicularly therefrom. Said sleeve 5 has an open end opposite with relation to said disk-shaped portion 4 and carries there an integral hollow flange 6 around said open end. When the button is fastened to said cloth I, said shaft 2 is inserted into the interior of said sleeve 5 where it fits closely and the male part moved relative to the female part until the flanges 3 and 6 firmly engage the part of the cloth I therebetween.

In order to prevent removal of the female part from the male part, I provide a bore in said shaft 2, at a point spaced from the flange 3, thereof, said bore extending transversally through said shaft.

Furthermore, I provide in the sleeve 5 of the female part a plurality of pairs of oppositely disposed apertures 8. Each pair of apertures 8 is centrally disposed with reference to the central axis of the sleeve and the apertures of each pair are in alinement, the axis of the alinement being transversal with relation to the sleeve 5. Each pair of apertures 8 is spaced from the open end of said sleeve 5 for a distance which varies for each pair of apertures. The apertures 8 are preferably arranged along the curve of a screw to permit the differences in distance for each pair of apertures from the open end of the sleeve 5.

Each aperture 8 has the same diameter as the bore within the shaft. A pin 'I may be inserted through one pair of opposite apertures 3 with which the bore has been selected to be put in alinement and thereby the female part and the male part are interlocked and thus restrained from relative movements against each other. I provide a plurality of pairs of opposite apertures V8 to accommodate various thicknesses of cloth.

When the button is fastened to cloth I the shaft 2 is first inserted through the cloth and thereafter the sleeve put over the shaft until the flanges 3 and 6 are closely adjacent the opposite surfaces of the cloth I. Then the sleeve is rotated with relation to the shaft until one pair of opposite apertures 8 appears in alinement with the bore of the shaft 2. Thereafter, the pin 'I which has a diameter permitting a close fit between the alined openings in inserted thereinto.

In order to facilitate the insertion of the pin '1, I provide a long rod of a diameter suitable for close tting into the apertures 8 and the bore and made of wood, plastic or other suitable material. This rod preferably has circular grooves at spaced intervals throughout its length, the intervals conforming to the outside diameter of said sleeve 5. Thereby, `the long rod may be inserted into the alined openings until it protrudes to the opposite surface of the sleeve at which point one of the grooves will be adjacent the aperture through which the rod was inserted into the sleeve, and then the rod is broken olf at that groove. This facilitates the correct gauging of the length of against the pin or if the parts are riveted together, by iiling olf the rivet heads and then expelling the remainder of the rivet.

In the modication shown in Fig, 3 the hollow shaft I0 may consist of a hollow rivet which commonly is provided with a flange.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as pin 1 without having to resort to great strength V in cutting it from stock. A l

Instead of making said shaft 2 out of a solid piece of material such as steel or plastic or the like, it may also consist of a hollow cylinder made of sheet metal or of other suitable material. In that case the bore which has previously been described will not be uninterrupted but will extend through the walls of the hollow shaft only.

In another modication of the invention which is illustrated in Fig. 3 I provide a hollow shaft Ill which cooperates with a hollow sleeve I2 to engage a cloth 9. Said sleeve l2 is open at both ends and engages said cloth 9 with one end and protrudes with its other end into a disc shaped element I4 to which it may be joined by welding, brazing, or it may be rolled thereinto, or otherwise be connected thereto by any other suitable well known method. This disc I4 is concave and, to provide a better appearing surface of a button, I provide a cover I5 which surmounts said disc I4 to cover the central aperture within said disc I4, through which the end of the sleeve has been inserted.

In order to prevent accidental removal of the pin '1 -Figs. 1 and 2-or I3, Fig. 3--from its emplacement transversally within the button, the surface of thepin is made to fit closely into the openings and has preferably a roughened surface determined by the selection of the material for the same. For instance, if the pin is made of wood, it will be very difiicult to remove the same from the openings. Should it be desired to make the connection between the male and the iemale parts still more permanent, a rivet may replace the pin and the two parts thus be riveted together.

In order to remove the pin from the button it may be expelled by axial movement applied illustrative and not in a limited sense.

Having thus described the invention, what I claim as new and desire to be secured by Letters Patent, is as follows: Y l. A fabric gripping button comprising a first hollow cylinder pointed at the one end and provided with an annular base at the opposite end, a'second hollow cylindrical sleeve adapted to slidingly t over said first cylinder and having a button head attached to its one end and means to secure the said two cylinders at a dilerent fabric gripping distance.

2. A fabric gripping button comprising a first hollow cylinder pointed at the one end and provided with an annular base at the opposite end, a second hollow cylindrical sleeve adapted to slidingly fit over said first cylinder and having a button head attached to its one end, said second cylindrical sleeve being provided with a plurality of spirally arranged oppositely alined aperture pairs and a pin to secure said two cylinders by means of said pin and said aperture pairs at a. different gripping distance.
