- 16 Claims.

This invention relates to devices for the insertion of tufts in fabrics for decorative and other purposes andis concerned moreparticularly with-a .novel manually controlled tufting instrument of the type that is sometimes referred to as an embroidery pencil and includes a reciprocating needle for inserting the tuft yarn and a presser foot for preventing the last inserted loop from being withdrawn upon insertion of thenext one. The new pencil is power driven, and it issoconstructed that the operator may insert tuft loopsIby-movingthe pencil in any direction over the fabric without the necessity of rotating the pencil to insure that-the presser foot mllalwaystrail-behind the needle in position to .perform its intended function. The pencil is, accordingly, much easier to handle than prior similar pencilsand by its use, fabrics with intricate tuft designs or with tufts extending along curved lines may be produced much-more rapidly than with prior implements.

In its preferred .form, the new pencil includes acasing, within which a needle bar is mounted for reciprocation lengthwise of the casing. The bar carries a needle projectible out of one end of the casing, as .the bar rec'iprocates, and a presser foot is mounted for rotary movement at thatendof thercasing and extends laterallyfrom thepath .of travel of the needle. The needle bar is free to rotate about its axis and is connected to the presser foot to move angularly therewith. The presser foot and needle thus have asfixed angularrelation andthe foot extends rearwardly from the .needle. .As the pencil is moved over the'ffabric in anydirectiomthe drag-of thetpresser foot on therfabric causes the foot to trail behind the needle at a'lltimes and .thiscauses the needle to .enter the fabric with the presser -footalways to the .rearof the needle in position to hold-the last inserted loop against withdrawal upon the nextinsertion of the :needle.

lEor a better understanding of the invention. reference may be made -.to the accompanying drawing, in which:

Fig.1 is a view .inlongitudinal section -.of one form .of the embroidery pencil of the invention; and

Fig. :2 is .a sectional view .on the line :II-eII o'fiFig.f1.

"The pencil .illustrated .in the drawing vcomprises .a casing ill) .of generally tubularshape and made-of any suitable material. FI he-casing is ..formed withan end ll of taperedzouter diameter, and its opposite -.-end is closed by a plug [2 threaded .in place. A slide 13 .is mounted within the .casing'for lengthwise movement, and a-rod Misattachea-to the slide and-extendsout through a bore through the plug 12. The rod is adaptedtobe-eonnected to means for reciprocating the slide-and may, for exampleybe .part of a flexible shaft enclosed within the usual .flexible casing -l 5 I and connected to aneccentric pin l6onra-disk l-l mounted on-a driveshaft 1-8.

A ball bearing 19 is mounted in the slide and the: inner ring of the bearing receives and issecured-to oneendof-a hollowtneedlebar 20. The bar thus reciprocates with the I slide but is free to move angularly relative thereto in the ball bearing.

A presser feet 21 is-mountedatthetapered end of -.the-casing and issprovided with a-tubularextension 2-2, which enters the end of the casing and receives a portion of the needle bar. The tube and presser foot are free to rotate about the axis of the 'casing but held against longitudinal displacement. For this purpose, the tube maybe formed with a crcumferential channel 23, in which a ballZlis-held by means of a screw-25threaded through the wall of thecasing.

The needle bar carries'a tubular needle -'26 at its .freeend, and the needle is-projectable out of the casing, when the needle bar is reciprocated by theslide. The free end of the needle is cut off at en angle-to giveit a beveled rearface 21, and the presser foot should extend rearwardly from the needle at all times in order that it may function properly. The presser foot is, accordingly, heldin.-prcperposition and against angular movementrelative tothe needle bar, and, for this purpose, that portion .of the needle bar, which :enters the tube 22, is square or otherwise non-circular in outlinezand-the bore of the tube 22 is correspondingly formed.

The yarn 28 is'supplied to the pencil'through a passage 2-9 through. the plug 12, and passes from the plug through the hollow needle bar andthence through'the'needleto project beyond the -,.pointed end thereof.

In the-operation-of the pencil, itris placed on the fabric with the presser :foot 2| in contact with the surface of the fabric and withthe needle over the spot where the first tuft is to be inserted. As the slide, bar, and-needle movedown, the needle enters the fabric, carrying the yarn with it. A loop of the yarn is inserted through the fabric by the penetration of the fabric by theneedle and the retraction of the latter, and, upon the insertion of a loop, the pencil is ad vanced to bring theneedle to the next-point where an insertion .is to be made. As the pencil is the axis of the pencil and the presser foot and needle bar have not been connected together against relative angular movement. As a result,

it is necessary to rotate such a pencil, when itis of direction is made, to insure that the presser moved along a curved path, or any other change foot will always be to the rear of the needle. The

operator of such a pencil must, accordingly, pay

strict attention to the position of the presser foot at all times. The new pencil is so constructed that the presser foot is always in trailing position, i

as the pencil is moved over the goods, and the operator may, accordingly, insert tufts in any direction without turning the pencil to insure that the presser foot will be properly positioned.
