` Curr BUT'rdN;
Application' med april `'4,
lily invention relates to improvements-in cuifbuttonspand itconsists in the combina.- tions, constructions, andE arrangements herein described and claimed. y
An object of my invention is to provide an improvement over my Patent No. 1,56 l,- 657, issued'December 8,1925, and my co-` pending application, Serial blo.A 111,353, Vfiled May 24, 1926, andl'allowed November 27, 1926.` The improvement consists in provid ing devicewhicli. isymore eiiicient forthe purpose intended, andwliich ismore certain in operation.
A further object of' my'invention is to pro vide a device of the'type' described in which the cooperating parts when pressedtogetlier slightly become engaged"7 and when pressed together morefirmly will be released y A further object of "inventionis to'provide a device/of the 'type described in'wllich the parts cannotbe `disengaged but become more 'firmly locked together whelrforce applied to pull them apart. 'y
A further object'of my invention is yto` provide a'device ofthe typed'escribedl which has novel means for retardingzthe movement of the locking mechanism for permitting tlie cooperating parts tofbe released from one another whenV pressed toward eachother.
t Other `objectsand y A in the following specification, and lthe novel features ofthe invention willl vbe particu larly pointed out inthe appended claims.`
My invention is killustrated in the accom-V panying` drawings, 4forming part of this application, in which Figure l is spaced-apart views of the male and female members of my cuff button, the female member being shown in section,
Figure 2 is a sectional view of my cuil button with the cooperating parts engaged,
Figure 3 is a sectionalview of my cuil button with the cooperating parts in position for disengagement, and y Figure 4 is a section along the line 1 -4:
In carrying out my invention l provide a male member A and a female member B. The male member A is provided with a reduced portion l having a shoulder 2 and a frusto-conical head. The reduced portion l tapers inwardly toward the head 3 providing a 'recess 4. A washer 5 is disposed concentric with the reduced portion l and normally held in engagement with the shoulder 2 by means of a compression spring advantages will appear isf/zr;` sex-iai No. meses.
6'L which is disposed concentric with the reduced portion l; 'Aspring-receiving comV partment T isv` provided for' receiving `the' springe.
Thellfemale member `BL is (provided `with a centralfopening S, 'tlie walls ofwliiclitaper outwardly.4 Diametrically-opposed' guide!" Y ways 9 -are disposedJ inthe wall1 of the openi inge. lAsleeve iOflias cuts-'l1 for a portion of its'lengtli equally spacedtherearouiid and'- forming a plurality of prongs 121 The prongs 'l2l arel provi-ded withi inwardly ex# tending integral lugs 133; The sleeve lOisVV providedat its lowerl extremity, view-ing Figures '1, 2 and '3, with a circumferentiallydisposed groove lll' which eXtendsth-rough the prongs v12,-land inl-,which is disposed-"a` resilientA retaining* members 1G aref integral' with they sleeve l() and receivable in -the guideways 9. The outer 'extremities of the' 1guifde'tv:iys 9' are smaller `than the diameter of the' retaining members- 16, thus providing `a-stopi for 'ther retainingmembers;l t
Aspreading ring 17 "is centrally mounted upona cover'll.A The cover 18 is secured to,l
ring Diametri"ally-opposed i 75 the female member B by `any `suitable means; The spreadinggring 17 is"provided with an arcuate-shaped engaging'surface 19.v
From the foregoing description-vof the variousV parts of the device,z theA operation thereof may be readily understood. The mal'e member Afandl tlie female member. B" are inserted' in the cuff 4of ashirt'sleeve in preciselylthesanie nia-mieres the ordina-ry type of separable cuiff linie-s,- whereupen the reduced portion l of the male `member is projected into 'the sleeve l() of the female member. By slight pressure inwardly uponl the male andv female members, the members will be moved into the locked position shown rate the male and female members by pulling outwardly thereupon, the prongs `12 will engage with the wall of the opening 8 and more permanently lock the members together.
lf the user is desirous of disengaging the male and female members, he may do so by 1 in Figure 2. If the user endeavors to sepa- 4 ing this movement, the sleeve 10 is rotated and the prongs 12 are forced outwardly by their engagement with the arcuate-shaped surface 19 of the spreading ring 17, see Figure 3. The outward movement of the prongs 12 moves the integral lugs 13 free from the annular recess 4. By releasing the male and female members, the compression spring G which is in engagement with the male member A and the washer 5 forces the male member free from the female member. By releasing the male and female members, the sleeve lO is also free to move outwardly, but is checked in its outward movement by the engagement of the retaining members 1G with the walls of the slots 9. Therefore, the speed of the travel of the male member away from the female member is greater than the speed of the travel of the sleeve 10 outwardly. The resilient ring l5, together with the resiliency of the prongs 12, is the means for moving the sleeve l0 outwardly.
l. A entf button of the type described comprising a male member, a head portion for said male member, said male member having an arcuate-shaped groove adjacent said head portion, a female member having an arcuateshaped groove extending downwardly therein, a sleeve carried by said female member, a retaining member integral with said sleeve and receivable in said groove, and retaining lugs receivable in the recess in said male member for locking said male member to said female member.
2. A cuff button of the type described comprising a male member, a head portion for said male member, said male member having an arcuate-shaped groove adjacent said head portion, a female member having an arcuateshaped groove extending downwardly therein, a sleeve carried by said female member, ay retaining member integral with said sleeve and receivable in said groove, retaining lugs receivable in the recess in said male member for locking said male member to said female member, prongs integral with said sleeve, said retaining lugs integral with said prongs, and means adapted to force said prongs outwardly for removing said integral lugs from said recess` for freeing said head portion and said male member when said male member and said female member are forced inwardly a. predetermined distance, said retaining member being moved within said slot and rctarding the movement of said sleeve, said prongs, and said retaining lugs into their normal posit-ions.
il. A device of the type described comprising a male member, a reduced portion integral with said male member, a head portion integral with said reduced portion, said reduced portion having a recess disposed adjacent said head portion, a female member having an opening therein, a sleeve movably disposed in said opening, retaining members integral with said sleeve and receivable in arcuate-shaped inwardly extending slots in said female member, resilient prongs integral with said sleeve, a resilient ring carried by said prongs, inwardly extending retaining lugs integral with said prongs and receivable in said recess when said reduced portion is disposed within said sleeve a predetermined distance, means for forcing said prongs and said retaining lugs outwardly for freeing said head portion when said male member and said female. member have been moved inwardly a }nedetermiiual distance, and means disposed concentric with said reduced portion for forcing said male member and said reduced portion free from said sleeve and said female member, said retaining members retarding the movement of said sleeve, said prongs and said retaining lugs into their normal positions.
