Application March 13, 1950, Serial No. 149,383

This invention relates generally to thimbles and in particular to athimble having a threadcutting device thereon.

Thimbles are well known in the art of sewing and are provided for the purpose of protecting the fingers against punctures by the needle. Thimbles are generally of a limited size sufiicient to be worn on the end of a finger and still permit flexibility of the fingers.

A person sewing by hand must necessarily cut the thread many times during the sewing of each article and this is conventionally accomplished by means of scissors or the like. Therefore, the sewer must stop and pick up the scissors each time a thread is to be cut, an operation which is time-consuming and irritating since scissors are readily hidden by the material.

It is proposed by the present invention to have cutting means instantly and constantly available to the sewer and thus permit rapid accomplishment of the sewing task.

Therefore, the principal object of the invention resides in the provision of a thimble or other tubular member of such size as to be carried snugly on the finger of a wearer and having thread cutting means thereon.

Another object provides for a thimble having cutting means thereon which is expendable and may be removed and replaced.

A further object provides for means which will positively cut a thread positioned thereon.

Another object provides for a thimble having 2 Claims. (01. 30-291) thread cutting means thereon which is protected I against the accidental cutting of the user.

Other ancillary objects will be apparentfrom the following detailed description when read in the light of the drawings in which:

Fig. 1 is a front elevational view of the invention applied to a thimble.

Fig. 2 is a sectional view taken along line 2--2 of Fig. 1.

Fig. 3 is a sectional view taken along line 3-3 of Fig. 1. r

Fig. 4 is a front elevational view of a thimble illustrating a second embodiment of the knife mounting means.

Fig. 5 is a sectional view taken along line 5-5 of Fig. 4.

Referring to the Figs. 1, 2, and 3, of the drawings, there is shown a thimble 10 having a portion thereof pressed outwardly to form a bridge II and apertures I2. Adjacent the upper aperture I2 is a vertical slot [3, the purpose of which will be hereinafter apparent.

A knife blade l5 having a guard 16 thereon is secured to a handle or shank ll of relative size to the aperture l2. The handle I! is arranged to be inserted in the apertures I2 and frictionally retained therein. The lowermost portion 20 of knife blade l5 resides within the slot 13 sulfi- 2 ciently to position the blade below the external plane of the thimble periphery but does not extend through the said slot. Therefore, a person using the abovethimble will not be cut by the portion 20 of blade l5.

As shown in Fig. 2, the blade is tapered thus insuring the cutting of the thread. The guard I6 has at the end thereof a hook member 2| which is spaced to provide a clearance between the side of the thimble and the said hook, in which the thread can be positioned. Subsequent pressure of the knife blade l5 against the thread results in the cutting thereof. In the event the pressure applied is insufficient to cut the said thread, the hook member 2| prevents the withdrawal thereof and pressure may be re-applied The thread being pressed downwardly is eventually cut by the blade by the portion thereof adjacent the said slot.

A second embodiment is shown in Figs. 4, 5, wherein a bridge member 25 is secured to a conventional thimble by soldering or other means and whereby a knife l5 may be inserted in the aforementioned manner. In this embodiment the portion 20 of the blade l5 abuts against the wall of the thimble and insures cutting of thread pressed thereon.

It is readily apparent that a person utilizing the instant invention can accomplish the sewing task rapidly and efiiciently without fear of accidental cutting of the material or of the fingers.

The blade assembly has been designed to be expendable, i. e., when the blade becomes dull and difilcult to cut thread with, thenthe said assembly may be removed from the thimble and replaced with a new sharp blade assembly. The replaceable feature is desirable and is achieved by the relatively simple and inexpensive construction thereof.

While two forms or embodiments of the invention have been shown and described herein for illustrative purposes, and the construction and arrangement incidental to two specific applications thereof have been disclosed and discussed in detail, it is to be understood that the invention is limited neither to the mere details or relative arrangement of parts, nor to its specific embodiments shown herein, but that extensive deviations from the illustrated forms or embodiments of the invention may be made without departing from the principles thereof.

What I claim is:

1. The combination with a tubular member of such size as to be carried on the finger of a wearer and having an outwardly struck portion with openings above and below the portion and another opening above said openings, of thread cutting means comprising a guard provided with a shank at its lower end for insertion into the openings in the struck-out portion to be supsuch size as to be carried on the finger of a wearer and provided with a loop at its'lower end and having an opening above the loop, of thread cutting means comprising a guard stamped from sheet metal and including a shank at its lower end which is inserted within such loop to support the guard, the central section of the guard REFERENCES CITED The following references are of record in the fileof this patent:
