BUTTON.

SPECIFICATION forming part of Letters Patent No. 453,570, dated J' une 2, 1891.

Application filed January 17, 1891. Serial No. 378,140. (No model.)

To all whom t may concern:

Be it known that I, FRANK E. WILLIAMS, a citizen of the United States, residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Buttons or Studs; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in buttons, studs, and analogous articles; and it consists of the construction and arrangement of the parts, as will be more fully hereinafter described, and pointed out in the claims.

The object of the invention is to provide a shoe adapted to be easily and readily arranged to enter a button or stud hole and adjusted to prevent withdrawal after insertion, the parts being simple and effective in their construction and operation.

In the accompanying drawings, wherein like letters of reference are used to designate correspondingr parts in the several views, Figure l represents a side elevation of a button or stud embodying my invention and showing the shoe arranged at an incline to the shank. Fig. 2 represents a vertical sectional view taken centrally through the button. Fig. 3 represents a perspective View of the parts of the button disassembled. Fig. 4 represents a View similar to Fig. 2, showing a locking or catch attachment.

In the drawings, A designates the head of the button or stud, which may be of any form and design, as desired, and has secured thereto a shank B, having its lower end formed into a footB, bent at an angle to the main portion of the said shank, being curved in an arc of a circle and slightly inclined. The shank converges toward said foot B', and said foot again widens so as to form shoulders B2, whereby the shoeis retained intact with said shank. Above said shoulders B2 the shank is cut away or reduced, as at B3, in order to provide a flush fitting of the edge of the shoe when operated with the shank, and thereby avoid projection of said shoe, which might interfere with the ready insertion or withdrawal of said shoe into and from the button or stud hole` I The shoe C is constructed with a back-plate C and a top concave-convex cap C2, the said parts inclosing a plate C3, having a convex s1de formed with a channel or groove C4, the

bottom of the latter being parallel with the convex side of said plate O3. The cap C2 is formed with a slot O5, extending from the center to the periphery thereof for movement of the shoe.

In assembling the parts the foot B of the shank B is set in the channel or groove C4 of the plate C3 and the cap C2 mounted thereover, so that the slot C5 thereof is in line with said channel or groove. The edge of said cap is then swaged down over the edge of plate O3. The plate C is then placed against the opposite side of the plate 3 and its edge swaged over the swaged edge of cap C2, thereby firmly holding the parts intact. The slot C5 in said cap C2 is of less width than the foot B of shank B, to thereby hold said bent end in positive engagement with said shoe, and the shoulders B2 reduce the shank to correspond to the width of the said slot to allow movement of one part upon the other.

To insert the shoe in a button or stud hole it is moved on the foot B until it assumes an angle of inclination to the shank and the reduced or cut-away portion B3 of said shank ts over the periphery of the shoe, and there- .by provides an unbroken alignment of the side of the shank and adjacent edge of the shoe. After the shoe is inserted it is pushed back until in central position over the shank when the button 0r stud will be firmly locked tgiinst displacement from the button orstud io e.

lt will be observed that a pivotal action is wholly dispensed with, and owing to the side walls of the channel or groove C4 of plate C3 a twisting or lateral movement of the shoe is prevented, the wear and tear being thereby received by said plate. Further, the unyielding convex surface ofthe plate C3 materially relieves the latter of strain by equally bracing it in all directions.

The double swaging liereinbefore set forth prevents loosening and displacement of the parts of the shoe, especially when the same is moved to an angle of inclination on the shank,

IOO

as in this position the strain is brought to Y substantially as'deseribed. Y

bear on the edge of said shoe, and without Said re-enfrorcement the tendency Would be to loosen the parts.

The converging form of the shank provides an increased securing-base for attachment to the button or studvhead and an attachment of re-enforecd strength is provided. It will be further noticed that by the construction Set forth I am enabled to useY a very short shank and bring the shoe closer` to the button-head, thereby making said head and shoe closely fit against the parts to which they are applied and avoid loose engagement.

The button or stud thus far described may be used with benecial and positive results without the addition of any form of lock or catch for holding the shoe in either ot' its adjusted positions; but it may be desirable in some instances to supply a lock or catch, and to provide for this in Fig. 4 I have shown the cap C2 formed with indentations c at about the center thereof, which engage the shoulders B2 of the foot Bl of the shank when the said shoe is centrally located. The end Yof said footY B is cut away or reduced to form a.

groove or shoulder c to engage said indentations o when the shoe is at an angle of inclination to the shank. By this means-the shoe is locked against accidental disengagement.

Having thus described my invention, what I claim is .Y 'Y

l. A button or stud having ashank with a curved foot at an angle thereto, combined with a shoe inclosing a plate with a channel or groove therein formed with a convex bottom.,

. 2. A button or stud havinga shank with a foot at an angle thereto, said foot being formed with a lower concave side, and a shoe having a convex surface, against Which the concave side of said foot has movable bearing, said parts being combined substantially as described.

3. A button or stud having a shank with a foot curved and bent at an angle thereto, combined with a sliding shoe having an inclosed plate formed with a channel or groove and engaged by said foot ot' the shank, said channel orI groove being of the same width as Vfoot bent at an angle thereto, combined with va shoe with a plate formed with a channel or groove to receive said foot of the shank, a slotted cap having its edge swaged down over the Yedge of said plate, and a back-plate having its edge swaged over the swaged edge of said cap, substantially as described.

5. Abutton or stud having a flat Wedgeshaped shank with its converging end at the bottom, from which extends a curved foot at an'angle thereto and Wider than the converged end of said shank, combined with a shoe having a convex bearing-surface for said foot, substantially as described.

6. A button or stud having a shank with a curved foot bent at an angle to the body of the shank, combined with a shoe having an inclosed plate with a convex side, and a channel or groove formedA with a convex bottom, a convex slotted cap, and aback-plate where- 'by the shoe may be adjusted at an angle to said shank, substantially as described.

7. A button or stud having a shank with a.

' curved foot bent Vat an angle to the body of the shank and provided with shoulders B2 and a reduced or cutaway portion, combined with a shoe having an inclosed plate with a convex channel or groove, a slottedl cap with indentations c, anda back-plate,substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
