THREAD PULLING TOOL Filed March 31, 1947 F l 7 INVENTOR,

BY 4 @Mw/we 0? W ATTORN EY Patented Apr. 18, 1950 UNITED STATES PATENT OFFICE 2,504,676 THREAD PULLING TOOL Edna M. Franklin, Oklahoma City, Okla.

Application March 31, 1947, Serial No. 738,413

6 Claims.

My invention relates generally to the dressmaking or tailoring art, and more particularly to a tool or implement by which seam threads may be manually withdrawn from the goods.

The principal objects of the invention are to provide a hand tool of this class which is handy to use, simple to operate, and positive in its thread gripping office.

Another object is to provide a tool for this purpose which is comparatively cheap to manufacture.

A further object is to provide a tool which has few moving parts to become worn or to get out of order.

Other objects will be apparent from the following description when taken in conjunction with the accompanying single sheet of drawing, wherein:

Figure 1 is a perspective view of the tool with its jaws in closed position, the dotted lines illustrating the open position of the jaws, and also depicting a thread engaged by the points of the two jaws;

Figure 2 is a fragmentary side elevational view of the jaw tips in closed position;

Figure 3 is a top view of the tips in closed position; and,

Figures 4, 5, 6 and 7 are transverse vertical sectional views taken substantially along the lines 4-4, 5-5, 6-6 and 1-'l respectively.

Like characters of reference designate like parts in those figures of the drawings in which they occur.

In the drawings:

The reference character A indicates, as a whole, an elongated element which constitutes the bottom body member of the tool. The bottom memher A has a comparatively thick handle portion I at its rear end. The forward end of the handle portion I terminates in a transversly extending forwardly facing abrupt vertical shoulder 2, and therebeyond, in a forwardly direction, there extends a thinner, vertically tapered blade portion 3, the side edges of which also taper in a forward direction. The extreme forward end of the blade portion terminates in a rounded or blunt point 4. The upper surface of the blade portion 3 is perfectly fiat, and the portion has a left hand vertical edge 5, looking from the rear, which be comes thinner as it gradually approaches the blunt end 4, but which at no place constitutes a cutting edge.

The reference character B indicates, as a whole, an elongated element which constitutes the top body member of the tool. The top member B also has a comparatively thick rear or handle portion 6 which is similar to the portion l of the member A, and which terminates at its forward end with a vertical shoulder complemental with the shoulder 2 of the bottom member A.

The top member B has a tapered blade portion I which extends forwardly from the handle portion 6, and which has a flat nether surface 8 adapted to lie flatly upon the flat upper surface of the blade portion 3 of the bottom member A. The blade portion 1 has a right hand vertical edge 9 which is dull to the extent that it does not constitute a cutting edge.

The two members A and B are pivotally connected intermediate their ends by a screw or pivot pin Hi, the connection being sufficiently loose to allow slight vertical play between the two.

The extreme forward end of the top member B constitutes a point I l which projects slightly beyond the blunt point 4 of the bottom member.

The handle portions I and 6 have adjacent vertical inside edges which meet when the members are pivoted so as to bring the blade portions in closed position, and the meeting line of the two edges is indicated in Fig. '7 by the reference numeral l2.

As is best illustrated in Fig. 3, when the handle portions are swung together, the two points 4 and II do not lie in actual vertical alignment, the point I l residing slightly to the left hand side of the point 4, so as to provide an elongated V- shaped opening 13 between the two points.

Fig. 2 illustrates the fact that the two points 4 and H are slightly bent arcuately in an upward direction.

The upper surface of the upper blade portion 1 has a boss M, the upper surface of which is cupped as shown at l5 to nest a persons thumb, whereby the upper blade may be swung laterally in relation to the blade portion 3 of the bottom member.

In utilizing the device for drawing seam threads from cloth, the tool is grasped in a persons hand in such a manner that forward portion of the bottom blade 3 lies on the posteriorsurface oi the second joint of the forefinger, with the upper surfaces of the handle portions being grasped by the little finger, and with the ball of the thumb nested in the cup I5 of the boss Hi. When the tool is in this position in the right hand, the other fingers fall naturally over the central por-' tion of the upper member B. Movement of the thumb toward the left hand will act to open the points 4 and II laterally.

7 thread will not be severed, but. instead, it will be forced to extend flatlybetween the upper surface of the blade 3 and bottom surface 8 of the blade 1. This is best illustrated in Fig. 4, where V in the thread is indicated by the reference numera1 l 6. Downward pressure of the thumb acts to hold the thread tightly impinged between the two blade points. A quick upward jerk or pull on the thread acts to pull one ormore of the threadloops from the cloth before the thread is broken.

The operation is repeated along the seam until it is completely withdrawn from the cloth. In Fig. l the cloth is indicated by the reference numeral H, and. the seam by. the numeral is.

From the foregoingdescription it is thought to be obvious that athread' ripping tool has been provided which is simple and handy to use, and which accomplishes all of the objects and purposes for which it is intended.

Obviously the invention is susceptible to some change or alteration without defeating its practicability, and I'thereforedo not wish to be confined to the preferred embodiment shown in the drawings anddescribed herein, further than I'am limited by the scope of the appended'claims.

' 2. A thread drawing tool including: two elongated body members pivotally connected together intermediate their ends; two elongated blade portions carried respectively by said members and having adjacent flat complemental faces slidably engaged in over-lapping relation with each other; and a sharp point on the end of one of said blades, said point projecting beyond the end of the other blade and being curved upwardly.

3. Structure asspecifiedin claim 1, in which the free end of the bottom blade is blunt, and the free end of the upper blade is sharp pointed and extends beyond the blunt end.

4. Structure as specified in claim 1, in which the free end of the bottom blade is blunt, and the free end of the upper blade is sharp pointed and extends beyond the blunt end, and in which the free end portions of both blades are complementally bent upwardly.

5. Structure as specified in claim 1, and: a boss on the uppersurfaceof the-uppermost blade, said boss having a. cavity inthe upper surface thereor for seating the ballot a persons thumb.

6. A thread drawing tool" including: two elongated body members pivotally connected to ether intermediate their ends-ytwo elongated blade portions carried respectively by said members and having adjacent flat complementalfacies slidably engaged in over-lapping relationwith each other; and a sharp point'on the end-ofone-of said blades.
