BUTTON.

To all whom z'z muy concern.:

Be it known that l, JOHAN GiviND Hae-v imno, citizen of Cliristiania,llorway, residing at Normanns Gate 9, Christiania, horway, have invented a new and useful Improvement in Buttons; and I do hereby declare the tollowingto be a full, clear, and exact description of the same.

This invention relates to improvements in separable buttons of the class having a back member consisting of a disk to which is tas tened a stem provided with a head, and a front nmber in the rear side of which there is provided an aperture adjacent which is a part having spring edges to engage and hold the head of the stem, and in which front and back members of the button are joined by forcing the stem otthe back member into engagement with the spring member of lthe front member. I

An object of this invention is the provision ot' new and improved means for .facili tating the connection and disconnection ot the front and back members of the button. For this purpose there is placed on the stem a sleeve having a diameter greater than the diameter ot the head of the stem and which may be forced into the aperture of the front member, whereupon the spring engagement ot the head is released and the back member and front member may be separated.

One embodiment of this invention .is illus trated in the accompanying drawings in which:

Figure l isa sectional view of the front and back members in connected position.

Fig. 2 is a sectional view showing the sleeve in engagement with the spring inember, when. the front and back members are to be separated.'

IFig. 3 is a sectional view of the button showing the front and back members during the separating operation. n

In the drawings lindicates the supporting plate of the back member and 2 a stem inserted into the same. The end of the stem 2 is formed with a rounded head 3, the front of which serves as a wedge and the rear part of which is out perpendicularly to the stem to form a shoulder. Upon the stem 2 is placed a loose sleeve 4 the diameter of which is greater thanthat of the head 3. The front member 5 has a spi'ingy convex part adjacent5 an aperture 6 therein.

rlfhe front and back members of the button are joined by forcing the stem 2 into the Speciiication of Letters Patent.

aperture 6. When entering the aperture the rounded head 3 cams the edges of the spring member outwardly until the shoulder on the head is in position to be engaged by the spring when the spring will move to this position and thereby arrest the head in said aperture. In order latter is forced toward' the front member. This forces the sleeve 4, by the plate l contacting therewith, into the sleeve 4, in entering the aperture forces the spring member until the edges thereof engage the surface of the sleeve. If theback member is now drawn rearwardly, the stem sllides in the sleeve 4, which at this time is e d spring members, until the shoulder orgtfie head 3 comes in contact with the sleeve. The continued movement of the back member draws the sleeve with it out of the aperture, the head 3 passing through the aperture G without the spring engaging the shoulder on the head because of the Contact of the sleeve 4 with the shoulder and the greater diameter of the sleeve. -The sleeve 4 is normally held out of engagement with the spring by the parts of the member 5 ad'acent the aperture 6.

uttons made according to the present invention have considerable advantage over the buttons heretofore known, since the former may be disconnected and connected again very many times without any appreciable wear.

Because of the comparatively great diameter ot' the sleeve 4 the Wearing of the button-hole of the garment is considerably reduced. l

I claim as my invention 1. A new article of manufacture of the class described comprising a front member having abutton head said front member being provided with an aperture andspring means adjacent said aperture; a bacljrfmem ber provided with Va stem and an enlarged head thereon having a shoulder adapted to enter said aperture and to be engaged by said spring means; and a sleeve mounted on said stem having a diameter greater than the diameter of vthe head and adapted to be inserted in said aperture to engage the spring means and to maintain the same out of range of the shoulder on the head when the front and back members are pulled apart, and said sleeve being adapted to preto again sepa-rate'the front and back members of the button the by the frictional engagement with the" aperture 6. The i vent the enlarged head from damaging lthe,

fabric to which the article of manufacture is applied when the head is Withdrawn through the fabric on the reino 'al of the button.

2. A button having a front member pro vided with an aperture and spring means ad jacent said aperture; a back member provided with a stem and an enlarged head thereon having a shoulder adapted to enter said aperture and to be engaged by said spring means; and a sleeve loosely mounted on sald stem and adapted to be inserted in said aperture by forcing inwardl;Y said stem and 'adapted by this movement to engage and release the rspring means. said spring means frictionally engaging said sleeve to hold the same until the head on said stem during its outward movement engages the sleeve, whereupon the head forces said sleeve out oi the aperture? said sleeve preventing the spring means from engaging the shoulder' on the head during theretraetion oi the head and sleeve through said aperture, and stopping means for normally holding said sleeve out of engagement with said spring means`r said stopping means being` adapted to .yield when pressure is exerted thereon by the sleeve in the preparatory operation of diseonnerting the front and bat-lt lmembers.

In testixnon)v whereof` l have -signed my name to this sperilieation in the presenee of two subscribing witnesses.
