JOHN P. DERBY, OF BOSTON, MASSACHUSETTS.

WRISTBAND-FASTENER.

Specification of Letters Patent No. 16,140, dated December 2, 1856.

To all whom it may concern:

Be it known that I, JOHN P. DERBY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Fasteners for Fastening the Vristbands of Shirts and for Securing Pins in Shirt-Bosoms; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l exhibits a face view. Fig. 2 exhibits a back view showing the fastener when closed. Fig. 3 exhibits a back perspective view showing' the fastener when opened. Fig. 4c exhibits a sectional view of the upper cross piece with hollow stem attached. Fig. 5 exhibits a sectional view of the movable wing of fastener which is connected by means of a post and lever to face plate. Fig. 6 exhibits a back view of fastener, the stems of which are constructed for eyelet holes.

Like letters referring to like parts.

To enable others skilled in the art to make and use my invention, I will state that my improvement consists in having attached to the face plate by means of a joint in center, a cross piece, at one end of which cross piece is an oblong stem, to the lower end of which stem is permanently attached a second cross piece running parallel with the first for about two thirds its length. To the other end of the cross piece first mentioned is attached an oblong or round hollow stem, through which a post passes which is connected at one end with the face plate by means of a lever, the other end of said post being attached to a wing or sectional piece of the second cross piece the operation being as the fastener is opened by turning the face plate one fourth around to open or swing said wing around at right angles with the fastener thus admitting of its being inserted into the button or eyelet holes of the shirt, and when so inserted, by turning the face plate back said wing is turned around so that it is parallel with the other parts of the fastener, in which position it is held and made firm and secure by a spring.

I will now proceed to describe my improvement more fully referring to the drawings.

A, A, A, A, Figs. 1, 2, 3 and 6 represen the face plate. v

B, B, B, B, Figs. 2, 3, A and 6 represent the upper cross piece.

O, C, O, Figs. 2, 8 and G represent the stationary part of second or lower cross piece.

E, E, Figs. 2 and 4, represent the hollow stem which is attached to cross piece B.

D, D, D, D, Figs. 2, 8, 5 and 6, represent the movable wing or sectional part of the lower cross piece which is permanently attached to the post, which is represented by the letter G.

F, F, F, Figs. 2, 3 and 5 represent a lever which connects at one end with the post Gr by means of the arm H, as is shown by Figs. 2 and 3, 5 and 6, and at the other end is connected with the face plate A.

P, P, P, P, Figs.'2, 3, 4: and 6 represent the joint which connects the cross piece B to face plate A.

N represents a slot in the face plate which a projection on the cross piece B enters when the fastener is closed.

When the fastener is opened as shown by Fig. 3 it will be readily seen that the stationary arm C, can be inserted into the button hole of Wristband, and when so inserted the section D can be easily entered, and when both are so entered by turning the face plate, the posit-ion of the lever F is altered which has the effect to swing around or turn the wing D thus closing the fastener. The face plate A being attached to the cross piece B by means of the joint H, is easily turned and when the fastener is closed it is held in place by means of the slot N which aprojection on the cross piece B, enters.

A fastener constructed with my improvement is easily adjusted, and can be as easily withdrawn, and it has the advantage of being applied for the purpose of securing pins in the bosoms of shirts. By referring to Fig. 6 it will be seen that when the cross piece C and the wing D are constructed of round wire it is adapted to eyelet holes which are worked in the shirt bosom to receive it, the advantages of this arrangement being that a pin can be inserted without creasing the shirt, and when so inserted it is perfectly secure against loss.

I claiml. Arranging and combining with a face plate in manner substantially as described two parallel cross pieces B and O one of which, the lower or second cross piece being constructed with a movable section D.

2. I claim the hollow stem E, through which the post passes that is connected with the movable section of the cross piece. I also Claim the arrangement of the lever H in connection with the face plate, and the movable section D of the cross piece whereby, by turning the face plate, the desired 10 motion is given to the cross piece or wing;

the whole making an eleetive fastener for the purposes described.

In testimony whereof IV have hereunto set my signature this twenty ninth day of October A. D. 1856.

JOHN P. DERBY.
