JOHNSON G. GRISWOLD, OF HARTFORD, CONNECTICUT.

IMPROVEMENT IN SHIRT-STUDS.

Specification forming part of Letters Patent No. 117,069, dated July 18, 1871.

To all whom t may concern:

Be it known that I, JOHNSON G. GRIswOLD, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shirt-Studs, and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference' being had to the accompanying drawing and to the letters of reference marked there- Like letters in the iignres indicate the same parts.

My invention consists in an improved shirtbuttonor stud, which can enter a button-hole freely without altering its shape, and when inserted will be held by a cross-bar, which turns on the center and springs into place when the top of the button is released by the fingers, thereby securing the button from being withdrawn.

Figure l is a side view of my invention. Fig. 2 is a section through the middle at right angles to Fig. l. Fig. 3 is a top view with the top shell removed to show the internal parts.

a' is the top shell, to which is attached the central stem b. c is the cross-piece at the bottom of the button Or stud. It is fastened to the stem b by means of a small pin Or otherwise. dis the under shell of the top part of the stud. To this is firmly attached the shank e which enters the button-hole. This shank is made long and tliin, so as to be about the shape of an ordinary button-hole'. In this shank is a hollow arbor, in which the stem b turns. The shank e and the cross-piece o are made of about the same shape, so that when they are turned in the saine direction they will enter the button-hole smoothly together. At the lower edge of the shank e is the lip f, against which the cross-piece o rests when it is turned to correspond with the shank. Its end also acts as a stop when the cross-piece is at right angles to the shank. s is a spiral spring, one end of which is attached to the stem b and the other to the lower shell d. This spring acts to turn the cross-piece o so that it rests in its position at right angles to the shank, being held by the end of the lip f acting as a stop.

To insert the improved button Or stud the crosspiece is turned so that it lies in the same direction as the shank, and is held in this position by grasping the head of the button. After inserting in the button-hole the head is released, when the cross-piece snaps out at right angles to its former position, under the iniluence of the spring s, and secures the button in its place.

Vhat I claim as my invention isl. An improved shirt-button or stud, constructed as described, having a cross-piece, o, which springs out at right angles to the shank e after the button is inserted, substantially in the manner herein described.

2. The combination Of the spiral spring s, the stem e, and the cross-bar c, substantially as described.

J. G. GRISW'OLD.
