SEWING ACCESSORY Filed May 19, 1951 United States Patent C SEWING ACCESSORY Ralph T. Bloxsorn, Flint, Mich., assignor of one-half to Walter l). Marr, Flint, Mich.

Application May 19, 1951, Serial No. 227,282

3 Claims. (Cl. StD- 298) This invention relates to a sewing accessory and particularly to a device which can be used as a thread cutter and for other cutting operations in sewing.

It is known to have a blade attached to a finger thimble to facilitate its use in sewing or other operations. The present device contemplates an improvement over these devices, and it is an object to provide a cutting attachment which may be applied to a thimble and also one in which the blade is readily removable so that it may be turned around to a known cutting position or removed and replaced.

It is a further object to provide an extremely Simple blade holding device which can be manufactured from one piece of sheet material, metal or plastic, and which by reason of its own resilience and by reason of its dimensions will tend to grip the blade when in position on the thimble.

Drawings accompany the specification, and the various views thereof may be brieily described as:

Figure l, a showing of the device in perspective in assembled position.

Figure 2, a side elevation of the unit in assembly.

Figure 3, an exploded view showing the various parts and their relationship prior to assembly.

Referring to the drawings, a thimble T of standard proportions and construction is illustrated. The blade holder consists of a spring cap formed of sheet material having legs and 12 curved in cross section to fit the thimble and intended to straddle the thimble at the closed end.

The legs are connected by a plate portion 14 which has formed centrally and diametrically thereof a groove or slot 16 having edges 18 and sides 20. The sides are connected by a bight portion 22.

The device is so arranged that when the

legs

10 and 12 are moved together to the position shown in Figure 3 the groove sides and edges 18 are separated to permit the entry of a blade formed of ilat steel with a cutting edge 32.

After the blade is dropped into the groove, as shown in Figure 2, and the legs are released, the outward motion of the

legs

10 and 12, due to the normal resilience of the spring cap, closes the groove tightly on the blade. Then, when the device is applied to a thimble, the wedging action on the

legs

10 and 12 is such as to hold the blade even more firmly in place and to permit it to be easily manipulated by the finger.

When the device is not in use, the blade may be inverted to put the cutting edge within the groove or the entire cap may be easily slipped from the thimble.

What I claim is:

1. A sewing accessory for application to and use on a nger thimble which comprises a piece of resilient sheet material shaped in the form of a U to have a bight portion about the size of the end of a thimble and leg portions to lie on opposite sides of the bight portion and shaped to engage the sides of a thimble, said bight portion being formed centrally with a depression extending diametrically of the bight portion and having resilient U-shaped walls to provide a transverse, expansible slot between the legs, a blade having a portion received in and retained by the walls of said slot, said walls being responsive to movement of said leg portions to open and close the slot due to the resilience of the material.

2. A sewing accessory for application to and use on a finger thimble which comprises a piece of resilient sheet material shaped in the form of a U to have a closed end portion about the size of the end of a thirnble and leg portions to lie on opposite sides of the end portion and shaped to engage the sides of a thimble, said end portion having a central depressed portion struck in the same direction as the legs to provide an elongate U-shaped in cross-section across the end portion inverse to the basic U-shape of the accessory, the portions of said end portion delining the edges of said recess being biased in contact, the walls forming said elongate recess being resilient to permit separation of said edges, a blade having a portion received in and retained by the edges and walls of said recess, said legs being manipulable toward each other to open said elongate recess to permit introduction of said blade portion and being movable away from each other to inuence the pressure of said edges on said blade.

3. A sewing accessory for application to and use on a finger thimble comprising, a plate formed with a depression extending diametrically thereof, said depression being dened by substantially parallel sides connected by a bight portion, a blade received in said depression and retained therein by contact with said sides and bight portion thereof, legs on said plate on each side of said depression, said legs and said depression lying on the same side of said plate with said legs generally parallel to said sides of the depression, said sides and bight portion being resilient and being inversely responsive to relative movement of said legs to permit insertion and removal of said blade, the distance between said legs being normally less than the diameter of a thimble, whereby insertion of a thimble between them will wedge them apart and lock said sides of said depression on said blade inserted therein.
