HENRY WOLCOTT, OF PROVIDENCE, RHODE ISLAND.

SEPARABLE BUTTDN.

Application filed. May 27,

T all whom it may concern:

Be it known that I, HENRY \VoL'ooTT, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Sepa rable Buttons, of which the following is a specification.

My invention relates to buttons of the separable type adapted conveniently, but not exclusively for use with cuffs.

The essential objects of my invention are security of the button members from accidental disengagement, facility of operation, and inexpensiveness and simplicity of construction.

My invention consists in the means for producing the results above specified substantially as hereinafter claimed.

In the accompanying drawings which form a part of this specification, and wherein like reference characters indicate like parts throughout the views,

Figure 1 is a side elevation, in central vertical section of a button embodying my invention, with the members interengaged,

Figure 2, a section of the same on line 22 of Figure 1,

Figure 3, a section taken on the same showing the parts at the instant of release,

Figure 4, a detail view of the spring member,

Figure 5, a perspective view of the link member,

Figure 6, a transverse section of the same on line 66 of Figure 5, and

Figure 7, a detail view of the tube.

In the construction illustrated my button comprises two socket members 8 and 9 of like construction. Each member comprises a tubular post 11, transversely split as at 12 to form two sections, but the sections may form a single integral structure A hollow head 15 is formed by a lateral dished flange 16 integral with the outer end of the post, and engaged by the rolled over peripheral edge 17 of a dished ornamental end plate 18. Integral with the lower end of the post is a lateral flange or shoe 20 provided with a bead 21 upon its periphery. Embraced by each post is a tube 23 having in this instance outer and inner external shoulders and 25 engaging the upper and lower extremities respectively of the post. Each tube 23 has a portion projecting into the 1924. Serial No. 716,113.

head 15 provided with a lateral transverse oblong slot 27.

A. link member '29, as shown in Figures 5 and 6, comprises a cylindrical body 30, necks 32 at the ends of the body triangular in cross section forming cam faces 33. Upon each neck is a cylindrical head 34 of the same diameter as the body terminating in rounded or inclined end faces 36. The cam faces 33 constituting the periphery of each neck extended to the peripheries of the body 30 and the adjacent head 34 forming an annular series of segmental slots 38.

In each head is a spring comprising a circular bearing portion provided with a diametrically disposed arm portion 41. The portion 40 rests against the interior periphery of the head 15 and the arm 41 is normally seated in the slot 27 of the tube.

The button is operated as follows. The link 29 is first engaged with one of the socket members if it is not already in engagement. This is effected by inserting one end of the link through the post, for instance of the member 8. As the link advances the rounded or tapering end 36 of the head 34 presses the spring arm 41, which is in the path of the head, outwardly until the annular series of slots 38 is reached whereupon the arm snaps into one of said slots and locks the link against longitudinal movement, the parts being in the positions shown in Figure 2.

To release the parts, the link is given a partial turn. The arm 41 which has been resting against a cam face 33 of the neck 32 is by the turning movement forced by the moving cam face outwardly until it reaches a position tangent to the body and head of the link, as shown in Figure 3, whereupon the link may be withdrawn.

The member 9 may be similarly engaged with or disengaged from the opposite end of the link member.

Vithout departing from the principle of my invention other modes of applying the principle may be employed instead of the one explained, change being made as regards the construct-ion herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I claim 1. In a separable button of the type set forth, a socket member comprising a hollow head, a tubular post supporting the head, a shoe upon the inner end of the post, a tube supported by the post extending into the head and provided with a lateral slot, :1 spring member comprising a circular body carried by the head and an arm registering in the slot, a link comprising a body adapted to enter the tube, a head adapted to engage the arm as the link is advanced, and a neck provided with cam faces extending to the periphery of the body adapted to engage and impel the arm.

2. In a separable button of the type set forth, two socket members comprising hollow heads, tubular posts upon the heads, shoes upon the posts, tubes in the heads supported by the posts and provided with lateral slots, spring members in the heads registering in the slots transversely thereof, a link comprising a body adapted to enter the. socket members, heads carried by the bodies, and cams connecting the body and heads and extending to the peripheries of the body and of the heads adapted to engage the spring members.

In testimony whereof I have aflixed my signature.

HENRY WOLCOTT.
