OSCAR A. ELLIOTT, OF YORK, NEBRASKA.
SPECIFICATION forming part of Letters Patent No. 463,351, dated November 17, 1891.
Application filed June 17, 1891 braska, have invented certain new and useful Improvements in Fastening Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
Myinvention relates to an improved safetyclasp or fastening attachment for securing pencil-holders or other articles, for instance, in or to the vest-pocket; and it consists'in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in perspective of a clasp embodying my invention, the same being shown in connection with a pencil-holder. Figs. 2 and 3 are end elevations of the same, showing different working positions of the lever. Fig. 4 is an end elevation showing the clasp swiveled to the pencil-holder. Fig. 5 is a view in perspective of the clasp detached.
The clasp in the main comprises a thin metal plate A bent back to approximately the inverted-U shape shown, and to the one leg of this plate is hinged lever B of the bellcrank-lever variety, the hinge being located at the elbow of the lever and the angle'of the lever being preferably about a right angle. The long arm of the lever extends along up the outside of the plate and is curved at b to form an elastic hook or look adapted to snap over the rounded section a of plate A, whereby the lever is locked in its closed position. \Vith lever B in the open position shown in Fig. 3, the clasp is slipped over, for instance, the edge of the vest-pocket, whereby plate A embraces the cloth, after which the lever is turned to the closed position shown in Fig. 2, by means of which the cloth is clamped between the end of the short arm of the lever and the opposing leg of plate A. To prevent the possibility of the clamp slipping on the cloth or other material-for instance, in case the cloth or material should be quite thinI provide the free end of the short arm of the $e'rial No. 396,607. (No model.)
lever with teeth, as at b,theseteeth presenting toward the opposing leg of plate'A when the lever is in its closed position, and the opposing leg of plate A may have teeth struck up, as at a, so as to present toward the teeth of the lever.
C, C, and 0 represent pencil-holders. In Figs. 1, 2, and 3 plate Aof the clasp is shown forming the one side of the pencil-holder. In Fig. 4 the pencil-holder and clasp are made separate and are then attached to each other by a rivet, as at c, and if the rivet is not'harnmered down too tight it will form a swiveled joint, so that the pencil-holdercan be turned on the rivet as an axis. In Fig. 5 the clasp is shown detached, and this clasp may be riveted, soldered, or otherwise secured to a pencil-holder, or to any other article desired. In the closed position of the lever (shown in Fig. 2) it will be observed that a smooth rounded edge is had'at the top of the device that will not catch the clothing and, hook I) being snapped over the upper section of plate A, there is no liability of the clasp being accidentally unfastened, so that it could be detached and lost. In fact any external pressure or rough usage applied to the clasp would have no tendency to unlock the lever.
The device is quite simple and inexpensive, and will be found well adapted to the purposes for which it is intended.
IVhat I claim is 1. A safety-clasp comprising an inverted U-shaped metal plate and a bell-crank lever hinged at the elbow thereof to the one leg of the plate, the short arm of the lever being operative between the legs of the plate and serving as a clamp, the long arm of the lever having an elastic locking-hook at the free end thereof adapted to snap over the upper section of the plate, whereby the leveris locked in its closed position, substantially as set forth.
2. A safety-clasp comprising an inverted- U-shaped metal plate and a bell-crank lever hinged to the one leg of the plate and having a 9 locking device, substantially as indicated, the
short arm of thWng teeth presenting toward the opposing tionpf the plate, substantially as set forth.
3. A clasp comprisingan inverted- U shaped metal plate and a bell-crank lever llinged' In testimony whereof I sign this specifici th'ereto, substantially as indicated, the short tion, in the presence of two Witnesses, this arm of the lever and the opposing section of 5th day of May, 1891.
the plate being respectively provided with OSCAR A. ELLIOT'I. 5 teeth for engaging opposite sides of the fab- Witnesses:
