MAGNETIC THIMBLE ATTACHMENT.
Application filed March 23, 1918. Serial No. 224,171.
To all whom it may concern:
Be it known that I, HENRY V. BRADFORD, a British subject, residing at Moose Jaw, in the Province of Saskatchewan and Dominion of Canada, have invented new and useful Improvements in Magnetic Thimble Attachments, of which the following is a specification.
This invention relates to a magnetic attachment adapted to be applied to a sewing thimble and it consists in the novel features hereinafter described and claimed.
An object of the invention is to provide an attachment of the character stated which is of simple and durable structure and which may be easily and conveniently used for picking up a steel needle from a smooth sur face, for lifting the same out of a crack or crevice or for removing the needle from a pile of pins or other articles which are come posed of material less responsive to the magnetism of the attachment than the material of which the needle is composed.
WVith this object in view the invention includes a thimble of conventional pattern having an opening at its smaller end and provided at its sides with inwardly disposed tongues struck up from the material of which the sides of the thimble are comosed. The attachment includes a tentiform body insertible within the needle and having a dome-shaped portion adapted to project through the opening at the smaller end of the thimble. The attachment is provided with a flange portion which fits snugly against the inner surface of the body of the thimble and the said flange portion is provided with an annular groove adapted to receive the inwardly disposed tongues of the body of the thimble whereby the attachment is securely held in position in the thimble and the dome-shaped portion thereof held projected through the opening at the smaller end of the thimble. After the attachment has been applied as indicated the perforations which are made in the sides of the body of the thimble by providing the tongues may be closed by glue or cement thereby permanently fixing the attachment with relation to the thimble. The attachment is composed of magnetized metal and consequently when the thimble is in position upon the finger of an operator the omeportion of the attachment may be iii-as with a needle whereby Specification of Letters Patent.

the needle is lifted out of a crevice, or crack, lifted from a plane or smooth surface or removed from an assemblage of pins or other similar articles.
In the accompanying drawing:
Figure 1 is a transverse sectional View of a thimble of conventional form as showing the'attachment applied.
Fig. 2 is a similar view cut on a plane at a right angle to the view illustrated in Fig. 1.
ig. 3 is a perspective view of the attachment.
As illustrated in the accompanying drawing the thimble 1 is ofmetal and is of conventional pattern. The said thimble is provided at its smaller end and at its center with an opening 2 The thimble 1 is provided at its sides and in the vicinity of the smaller end with inwardly disposed tongues 3 struck up from the metal of which the body of the thimble is composed and the formation of the said tongues necessarily produce adjacent openings at the tongues the said openings being in the sides of the thimble 1.
The attachment comprises a tentiform body 4 of metal which is magnetized The said body 1 is provided at its smaller end with a dome-shaped portion 5 adapted to ass through the opening 2 in the smaller end of the thimble 1 when the parts are as sembled. The body 4 is further provided with a substantially cone-shaped flange portionfi adapted to fit snugly against the inner surfaces of the sides of the body of the thimble 1. The flange 6 is provided with an annular groove or depression which is adapted to receive the tongues 3 provided at the sides of the thimble 1 and hereinbefore described.
It is obvious that to assemble the parts the body 4 is inserted within the thimble and the dome 5 is projected through the opening 2 of the body of the thimble. When the body 1 is inserted in the thimble 1 the tongues 3 will spring into the groove 7 and consequently the magnetic attachment is connected with the thimble. To permanently secure the attachment within the thimble the openings which are about or at the tongues 3 may be filled with glue or cement which will adhere to the bottom of the move 7 and fix the body 45 with relation to the thimble 1.
When a thimble supplied with the attachment as indicated is applied to the finger of an operator it may be used to advantage for close proximity to the needle whereby the magnetism will draw the needle toward thedome 5 and" the ne'edle'will adhere thereto;
Therefore the needle maybe lifted orraised same and-in the, event that. the needle is mixed with a number!- of pinsor other articlesaotheaneed'le may; be lifted by moving the dome-shaped portion over. the assemblage for the reason that the needle Will respond.
' moreqnickly? bottle/magnetism: ofwthe 1 attachment by reason of the character of the mate- 'picking up a' needle for the exposed 'end'por' tion of the dome 5 may be placed upon or in passed over the needle soxthat it isrial of which the needle is composed, than the pins or other articles.
Having described the invention what is claimed is In combination with a thimble body provided at its smaller end with a circular opening defining an inturned flange surrounding the opening, a cylindrical member of magnetic material located in the body under said flange and provided in its periphery with a groove, a reduced extension on said member extending through said circular opening and having its extremity projecting beyond the smaller end of the'thimble, the projecting end of said reduced extension being curved more abruptly, thanthe end of the thimble, and a plurality of inwardly extending tongues stamped from said thimble body at a point spaced from the? smaller end thereof and engaging Within saidcove.-
, In testimony whereof,-I a x my signature.
