(Cl. LIL-152)) Claims.

fllhe present invention is directed to :sewin machines and more particularly 'to can aattachment after :such machines 'fpr rthe purpose 10f :gu'idingfabric to zthe-sewing mechanism.

(In the production :of zvjarious articles on arsewingmach-ine, it becomes-necessary tosew together relatively ions zp'ieces silabric zwhichmaybe relattvely -wide and=-hulkyi :In vaceoirmlishing this the operator aOfiJBIl :has :diflicultybecause of the tendenoy of :the fabric to :twist and turn, thus slowing the operations and otten producingdefective goods. fiorvinstanoe, inxzthe :sewing of a :ruflled edge zto curtains, the tpieces iof :Eabric to be sewed together are relatively :large and the operator has difliculty in keeping the piecesiinathe'ir proper In practicing the present invention there is I provided a standard which is usually attachedto the bed of the'sewing machine having an arm thereon at the upper portion for guiding a strip of :fabric over the same from 'one side of the sewing machine. A lower-arm is provided having a frame which acts as a guide for the fabric passing over the upper arm and makes certain that the :fabric {approaches theneedles of the sewin machineinthe proper position without'the possibility'of shifting or wrinkling.

In the accompanying drawing constituting a part hereof and in which like reference charactersindicatelike parts,

Fig. -1' is a top "plan View of a fabric guiding attachment made in accordance with the ,presenit invention, some parts being broken away forclearness; v

Fig. '2 is aside elevational view thereof; and Fig. 3 is a vertical cross-sectional view taken along the-line 33 of Fig. 1. I The sewing machine "is illustrated fragmentaril-y -by bed I' on which is mountedhead 2 and a pair of needles 3 which are operatediby the mechanism of the sewing machineas usual.

Fixed on bed I is ,a base ,4 having la vertical Standard 5 integrally herewith. standard a 2 is :hollow and an extension *5 is adapted to fit therein with a l setascrew l for clamping extensien :5 in various positions. A horizontal arm 8 passes through an :opening in the top of extension :6 iand-assetscrew :9 is adapted to'clamp the sameinadiusted position which may be varied at will. Apair'of end guides l-llfitted with suitable setz acrewsrareprovided on arm 8 and the spacing thereof is iadjustedito suit the fabric to be sewed.

A block 1H fits around standard 5 and is held in adjustable position by set screw I2. .A pivoted member :13 having an extension l4 passing through ;an opening in block H is held in positionsby-nut +5 and spiral'spring was best shown in Fig..1.- Aright-angleextension IT has one leg passing :through-an-opening in member 13 and set screws 8 hold :the same :in adjusted position.

The other leg 1:9 has secured thereto a block 20. integrally united with said block is a plate 21 andfsaid block and plate are held in position on leg-k9 byzset screws :22. A pair of guides 23 adapted it) ;be clamped in place by set screws 2'4 are provided on leg *9.

Secured to plate :24 are a pair of .lateralstrips Zion-whichaaframeis mounted. 'The frame consists of :aside member .25 adjacent to the sewing machine, aniend'member (21 st right angles thereto "and :an opposite :side member 28 parallel to 25. The Era-me :is "completed by an angularly placed .membertzll which is usually at to member .26.

The opposite end 39 connects 26 with 28. fillxof said frame elements are preferably onade :of a single :piece of wire or rod. A folded piece 'of sheet :metal 3| secured to the frame at 33,0 provides means to guide fabric to the --sewing machine. 1

.llnioperation guides to and 23 areadjusted and set ifor the proper :width 1of the fabric to be sewed and in proper relationship to the frame. A relatively long piece of fabric is placed usually in a basket directly below arm :8 and the end thereof is guided between guides til, then downwardly in front of leg as and between guides 23. The

fabric then passes under the frame and is folded over the top :thereof around member .23. The edge thereof .is held in member 431 so as to gu de it properly with respect to the needles. In the operation the operator has asnitable fabricdirectly .under the trams and matches the edge thereofwith theledg'e of thestripiof fabric .passing toverlsaidframe and to the needles. In this manner, .the two pieces of fabric may be easily guided to the needles by theroperator. 1

y when thesew-ineoperation-is complete orfnder other suitable circumstance where the guid Although the invention has been described setting forth a single embodiment thereof, it will be apparent to those skilled in the art that many changes in the details of construction may be made without departing from the principles set forth. For instance, some of the sliding connections may be omitted or the equivalent of the adjustments may be provided by other wellknown means. Ihe standard need not rest upon the bed of the sewing machine but may be secured to a floor or any other stationary element. The frame need not be of wire as other forms thereof are suitable and the attachment thereof to the standard may be of different mechanical construction. These and other changes in the details of the invention may be made within the spirit thereof and the invention is to be broadly construed and not to be limited except by the character of the claims appended hereto.
