Patented Aug. 28, 1934 STRING CUTTING DEVICE George Genda,

Application July 10, 1933, Serial No. 679,793

1 Claim.

This invention relates to improvements in cutting devices and has particular reference to a device for cutting string, thread and the like.

A further object is to produce a device which may be worn upon the person, thereby eliminating the necessity of continuously looking for a cutting implement such as a pair of scissors.

A further object is to produce a device which is economical to manufacture, one which is light in weight and, therefore, which will not hamper the movements.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a side elevation of the device as the same would appear when worn upon the finger in the manner similar to the wearing of a ring,

Fig. 2 is a side elevation of my device as the same would appear when attached to a wrist strap,

Fig. 3 is an enlarged detail cross sectional view on the line 3-3 of Fig. 4,

Fig. 4 is an end elevation of the device as shown in Fig. 3, s

Fig. 5 is a perspective view of the cutter and a piece of string positioned therein,

Fig. 6 is a similar View of my device showing the raised position of the cutting finger, and

Fig. 7 is a perspective view of the ring mounting.

In sewing, and many similar occupations, it is often necessary to cut string or thread, and when the necessity arises a pair of scissors or a knife must be located and employed. This causes considerable delay and extra effort on the part'of the user. Applicant has, therefore, devised a simple cutting element which may be worn upon the person and, therefore, one which, will always be available when needed.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a supporting structure.

in Fig. 2 the supporting structure is designated by In Figs. 1, 3, 4 and. r 7, this supporting structure is shown as a ring and Pasadena, Calif.

the numeral 6 and takes the form of a strap. Mounted upon the supporting structure, in any convenient manner, is a base plate 7 having an upstanding lug 8 which has a cutting edge 9. Pivoted to the lug 8 is a finger piece 11 pivoted as at 12 and having a cutting edge 13.

A spring 14 has one end secured to the base 7, by having the end thereof inserted in a slot 16 and has its opposite end contacting the finger piece 11. The base 7 may be connected to the ring 5 in any convenient manner, as for instance, bya screw 17. A cover 18 is preferably placed over the device as indicated in Figs. 1, 2 and 3, which cover is removable and is secured through the medium of a screw 19.

and 13.

By now pressing upon the finger piece 11 the same will be pivoted to the position of Fig. 6 and the string will be severed. Upon release the spring 14 will return the parts to their normal position.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangements of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:--

In a device of the character described, a ring forming a support having a flat surface, a base plate removably secured to said flat surface, said base plate having a vertically upstanding lug, said lug being provided with a cutting edge, a finger piece pivotally secured to said lug and having a cutting edge capable of contacting the cutting edge on said lug to produce a shearing action, a spring secured to said base and to said finger piece; and a c'o-ver mounted on said ring and enclosing said base plate, said cover having a slot formed therein and in alignment with said vertical cutting edge of said lug.

GEORGE GENDA.
