Specification of Letters Patent. r

PatentedOct. 27', 1914..

Application filed September 26, 1902. Serial No; 125,002. 1

To all whom it may concern Be it known that I, VVILLARD C. Lirn, a citizen of the United States, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Needle, of which the following is a specification.

This invention relates to needles particularly applicable for use in machines for sewing brooms and similar articles of the class set forth in my pending application, Serial No. 106,831, filed May 10, 1902, and has for its object the production of a needle which is simple in construction, is readily threaded, and is highly effective in use; and to this end it consists in the novel combinations and constructions hereinafter described and claimed.

In describing this invention, reference is had to the accompanying drawing in which like letters indicate corresponding parts in all the views.

Figures 1 and 2 are similar side elevations of a preferable construction of my needle, the latch being illustrated in different positions. Fig. 3 is a top plan of the needle as shown in Fig. 2. Fig. 4 is a 1011- gitudinal sectional view taken on line AA, Fig. 3. Figs. 5, 6 and 7 are sectional views taken respectively on lines 13 -13, (1-0, and H The illustrated preferable embodiment of my invention consists of a main part 1, and

a latch 2. Said main part 1 is provided atits front-end with a re'arwardly projecting barb 3 and its eye 4 extends forwardly from anupper outer surface 5 and opens through diverging upper and side surfaces 6, 7 at opposite edges of the barb 3, being extended substantially lengthwise in the surface '6 and diagonally throughthe surface 7 and through a lower surface 8. The eye 4 is usuallyprovided at its front end with a substantially upright thread-engaging surface 9 having its upper and lower ends extended forwardly, and with diverging branches 10, 11, which respectively open through the upper; and lower surfaces 6, 7 and form thread passages. The outer side surface 12 of the rear end of the barb '3 is arranged within the plane of side surfaces 13, 14:, at the front and the rear of saidbarb. One side surface 15 of the main part 1 is generally flat and formed with a round ing upper edge, and the opposite side sun face is extended at its upper and lower parts toward the surface 15. I

As clearly seen in Figs. 5, 6 and 7, this needle is substantially triangular or wedge shaped in general outline in cross-section, the fiat face 15 and the rounding face 7 engaging the fibers respectively at opposite sides of the needle and said faces meeting at an angle forming the point or edge of the wedge; and the point of the barb 3 is located directly opposite to the edge of the wedge in substantially the plane of said face 5 and between the faces 7 and 15.

The latch 2 is mounted in a lengthwise groove in the upper surface or edge of the part 1, is movable therein intoand out of tion 17, see Fig. 7 and as provided with an integral spring arm 20 for detachably engaging the shoulders 18. 1

When my needle is supported as illustrated in my aforesaid application, it is se-' curedto a holder which is" mounted on a rocking arm and'is provided with a spring for holding the latch 2 in engagement with the barb 3, but I have not shown any sup-' porting and actuating means herein for the needle as the same are not regarded as a part of my present invention.

As will be obvious" to those skilled in the art, the operation of my needle is as follows:

The main part ofthe needle and the latch move together until the point of the needle has passed through the broom, or] other article, whereupon the engaging member 19:

of the latch encounters one of the banding cordsof the broom and restrains the of the barb 3 may be separatedfromthe latch to permit the entrance of the thread to the eye 4 at the rear of said, barb. As the member 19 is adjustable on the main desired. After the rear end of the barb3 passes through the broom or other article,

the thread is admitted-to the eye 4 at the rear of said barb and the ready entrance of said thread within the eye and beneath the barb 3 is greatly facilitated by the arrangement and construction of the eye. Upon the return of the needle the thread is drawn against the surface 9 and into the branches or thread-passages 10, 11. Thethread then extends from the upper and lower surfaces or edges of the needle and as the needle passes rearwardly through the broom the thread passes through openings in the broom normally present above and below said upper and lower surfaces or edges of the needle. It is thus apparent that the force necessary to return the needle with the thread, and the wear upon the thread, is reduced to a minimum. Moreover, the arrangement and construction of the surface 9 also reduces the wear upon the thread when drawn through the broom by the needle. During the return of the needle, the latch 2 and the inclined edges of the portion of the eye opening through the surface 7 and the arrangement of the point of the barb prevent the entrance of the contiguous straws of the broom within the eye. The surfaces 13 and 14 also add to the efliciency of the needle by forcing the contiguous straws of the broom outwardly beyond the plane of the outer side of the rear end of the barb 3 and thus reducing the strain thereupon. The flattened surface 15 is also a. feature of advantage as a needle when provided therewith is somewhat thinner than would otherwise be the case and makes an opening of minimum width.

The construction and. operation of. my needle will now be readily understood upon reference to the foregoing description and the accompanying drawing and itv will be obvious to those skilled in the art that more or less change may be vmade in said needle without departing from the spirit of my invention. a

What I claim as newand desire to secure by Letters vPatent of the United .States is 1.- A needle for sewing brooms and similar articles, the same being substantiallytrian: gular in general outline in cross-section and providedwith an eye opening through two adjacent; sides of the needle and extending inwardly and forwardly forming a.rearwardly extendinghbarb, the eye. atthe portion thereof nearest the point of the needle openingthrough one of said adjacentfaces near'the edge formed by the last-mentioned face and athird face of the needle, and the point of'the barb being located between one of said adjacent faces and the third face of the needle, substantially as and for. the purpose described.

2. The combination with aneedle for sewingbrooms and similar articles, thesame being substantially triangular in general outline incross-section and provided with an eye opening through two adjacent sides and extending inwardly and forwardly, and thereby forming a rearwardly extending barb; of a latch mounted on the needle and movable along one of said adjacent sides into face located at the side of the needle directly opposite the edge of the wedge and thereby forming a rearwardly extending barb, substantially as and for the purpose set forth.

4;. A needle for sewing brooms, the needle being substantially wedge-shaped in crosssection and having a substantially flat face and a curved face, said faces meeting each other at an angle and forming the edge of the wedge, and the needle being also formed with an eye opening through the curved face near the edge of the wedge and also through the third face located at the side of the needle directly opposite to the edge of the wedge, the eye thus forming-a rearwardly extending barbhavingits point located between said curved face and said flat face which meet to form the edge of the wedge, substantially as and for the purpose described.

5. A needle for sewing brooms and similar articles, said needle being substantially wedge-shaped-in cross-section and having a substantially fiat face and a curved face at opposite sidesof the needle, said faces meeting each other at an angle and forming the edge of the'wedge, the needle being formed with an eye extending inwardly and forwardly, and. opening.. through the curved face and through the third face located at. the side of the needle directly opposite the.

edge of the wedge, and thereby forminga rearwardly extending'barb between the two first-mentioned faces, substantially as and for the purpose specified.-

6. A. needle for sewing brooms and similar articles, said needle being, substantially wedge-shaped in. cross-section, opposite faces of the needle meeting and forming the edge ofthe wedge, the needle being formed'with an eye extendinginwardly and forwardly and openingthroughrone of said faces and through the third face located atthe side the wedge and thereby forming a, rearwardly extending barb, and alatch movable along said third face into and out of en gagement with the point of the barb, substantially as and for the purposeset forth.

7 The combination with the main part of a needle for machines for sewing brooms and similar articles; of a latch movable with,

and relatively to, the main part of the nee dle and comprising a main memberprovided W1th a prO ectmg portion havlng shoulders arranged one in advance of the other, and

an engaging member mounted on said proectmg portion and provided with a spring arm for cooperating with saidshoulders,

substantially as and for the purpose described.

erate with any one of said projections to lock said member to the latch, substantially as and for the purposespecified.

9. The combination with a needle formed with an inwardly and forwardly-extending eye and a rearwardly extending barb, of a latch mounted on said needle to cooperate With the barb, an engaging member carried by the latch and capable of adjustment relatively thereto, and cooperative means carried by the latch and engaging member to lock said latch and member together to prevent relative movement of the parts, substantially as and for the purpose set forth. In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at the city of Washington and District of Columbia, this twenty-sixth day of September, 1902.
