Y THOMAS W. FEELEY, OF PROVIDENCE, RHODE ISLAND.

SLEEVE-BUTTON.

SPECIFICATION forming part of Letters Patent No. 240,241, dated April 19, 1881. Application filed March 5, 1881. (Model.)

To all whom it may concern:

Be it known that I, THOMAS W. FEELEY, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Sleeve-Buttons; and l declare the following to be a specification thereof, reference being had to the accompanying drawings.

Like letters indicate like parts.

Figure l is avertical section of my improved button on the line x 0c of Fig. 2. Fig. 2 is a plan of the under side of the button, and shows the cross-bar in transverse longitudinal section on the line z z of Fig. l.

My invention relates, particularly, to the mechanism for holding` in position a revolving cross-bar or shoe of a sleeve-button 5 and it consists of a square aced shank in combination with a tubular cross-bar, the latter inclosing springs and friction-blocks to engage with the opposite plane surfaces of the shank, thus holding the cross-bar in place at each quarterrevolution.y

The button A has rigidly connected with it at its central point a square shank, B. An elliptical or straight post, C, permanently afliXed to said button, extends around and from the shank B, as shown in Fig.1. A cross-bar, D, is mounted upon the shank B, the length of which should be equal to the major axis of the post O. The cross-bar D is tubular, and midway its length turns upon the shank B, at a right angle thereto, being kept in the plane of its revolution by the head a of the shank B upon the outer side, and 'by the end of the post O upon the inner side. Within the tubular cross-bar are two friction-blocks, b b, made preferably of transverse sections of wire, and which form Wearing-surfaces against the shank as the bar revolves, and are kept in engagement with the shank and the rectangular faces thereof by means of spiral springs o c. These springs have their bearings 0n one side against the blocks b b, and on the other against the interior surface of the flanges or inwardlybent ends of the cross-bar, as shown in section in the drawings. A central aperture, d, is thus left at each end of the cross-bar, and the spiral springs are inserted within the tubular bar by entering the end of the wire through the aperture d, and advancing them respectively into position by a spirally-twisting or screw-like motion. The reason of this method is. that asIconstruct and put together the parts of the button above described with hard solder, the heat would destroy the temper ofthe springs if they were inserted before finishing the bar and button. By the device described I can place the springs in position after all the other parts of the button are linished.

The button, thus constructed, easily enters the button-hole, and is secured therein. In entering the button-hole the cross-bar D is placed lengthwise along the major axis of the post C. 'lhe bar and post, thus lying in the same plane, pass through the button-hole without hindrance, and then the bar is turned a quarter revolution, at which point the locking mechanism again holds it, as indicated by dotted lines in Fig. 2. Y

I claim as a novel and useful invention, and desire to secure by Letters Patent- 1. The tubular cross-bar D, having theJ springs c o and friction-blocks b b, in combination with the square-faced shank B, as and for the purpose specied.

2. The improved button herein described, consisting ofthe button-front A, square-faced shank B, post (l, and tubular cross-bar D, mounted and turning upon said shank B, and held in engagement therewith by thev springs c c and friction-blocks b I), all arranged and operating substantially as specified.

THOMAS W. FEELEY.
