JOSEPH H. DOLL, OF NEWARK, NEW' JERSEY.

SLEEVE OR COLLAR BUTTON.

SPECIFICATION forming part of Letters Patent No. 319,4:6'7, dated June'9, 1885.

Application filed January 23, 1885. (No model.)

To wZZ whom it may concern.-

Be it known that I, J osnrn H. DOLL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Sleeve and Collar Buttons, of whichthe following is a specification.

My invention relates to that class of sleevebuttons in which the smaller disk is hinged so that it may be turned nearly or entirely in line withthe shank to allow it to be passed freely through the button-holes; and the object of my invention is to provide a ready and effective locking means, which will hold the two disks of the button firmly parallel to each other until it is desired to unlock them. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, partly in section, showing the button unlocked. Fig. 2 is a central section showing the parts locked, and Fig. 3 is aperspective view seen from below.

All the figures are represented on an enlarged scale.

Similar letters refer to si milar parts throughout the several views.

A is the large disk or button proper; B, the small or tilting disk. 0 is the outside shell of the shank, and O that part of the shank which slides inside the shell 0. To this piece 0 the disk B is hinged by the pin b. O is partly hollow, to receive a coiled spring, d, which tends to press this piece out of the tube 0 to allow the disk B to tilt.

To prevent G from disengaging entirely from the tube 0 by the force of spring (I, a small round-headed screw, 0, is screwed into the piece 0, which slides in a longitudinal slot, 0, of the tube 0. The slot 0 is long enough to allow the hinged part to project out of the tube 0 just so far as to allow the disk B to turn in line with the tube 0, or nearly so.

At the lower end of the slot 0 is a short circumferential slot, 0*, slightly inclined-a part of a screw-helix-or, in other words, the two slots form an obtuse angle with each other. This angle, however, must be but little above ninety degrees to insure a firm interlocking of the parts under all conditions.

After the button, as represented in Fig. 1, has been passed through the button-holes, B is turned, pressed down toward A, and at the same time alittle revolved. By this part revolution the screw 0 engages with the slot 0 and, owing to its slight incline, draws the disk B firmly against the end of the tube 0, making the whole virtually like one solid piece. A reverse motion of the diskB brings the screw 0 into the longitudinal slot c,when the spring (Z begins at once to exert its power and push the piece 0 out of the tulocGto its full extent, carrying with it the disk B, which latter drops immediately by its own gravity to the lower side of the shank.

To insure very firm interlocking, I prefer to make the screw 0 with an enlarged head, and reduce the thickness of the tube-metal adjoining the longitudinal slot, so that the screw will move freely in the latter, but the head will rub hard against the outside of the tube in the inclined slot 0 producing an additional friction, and consequently creating a stronger hold with less or no chance for an ac cidental unlocking. I believe, however, that it will suffice to have the screw flush with the outside of the tube O, which would make this arrangement more preferable, as the projecting head might tend to wear out the buttonholes too soon.

I am aware that prior to my invention sleevebuttons have been made with hinged disks. I therefore do not claim the hinged part, broadly; but

What I do claim, and desire to secure by Letters Patent, is

1. The hinged disk B and sliding piece G, in combination with the coiled spring (1, screw 0', and longitudinal and inclined locking-slot c a, substantially as and for the purpose herein set forth- 2. In a sleeve-button, the piece 0, sliding inside the fixed slotted tube 0, actuated by the spring d, and held in place by the stop 0, substantially as described.
