*Be it known that we, WILLIAM L. BARRON and Fnrrz El Os'oL, citizens "of the United States, residing, respectively, at New York in the county and State of New York, and Elizabeth, in the county "of Union and State of New Jersey, have invented certain new and useful Improvements in Sewing- Machine Guides,"of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for'its'pri niary object to provide a simple and effective device'for opening out the uniting seams of superposed plies of fabric stitched together aIong'their marginal portions forapplication of covering or fastening seams at their junctions.

In its preferred form, the improvement consists in a guide formed of a sheet metal plate having on Opposite edges atone end "lateral wings which are bent over the "body ofthe plate toward each other but spaced apart to form a. work-guiding channel having a longitudinal opening 'in its upperside, said plate having secured thereto 5 one end of a spring-plate whose opposite end extends within the channel and sust'ains'afguidetongue affording a partition for the chan- "nel directed intermediate the edges of said opening. As thus co'nstructed,the' guide affords an upwardly contractedpartitioned channel to ,receivethe marginal portions of the two plies of fabric which are separated by the guide-tonguejentering the crease between them and spread apart'laterallyby. the supporting spring-plate suffic ently to be fiattened outby the-action of the presserfoot, the throat plate and the ii'e'eding device of the sewing machine at the stitching point. The essential; elements of :the guide are the spaced'and o-pposed edges ofthewlngs "whichlconfine'between them theparts of the superposed plies "of I fabric containing the initial uniting seam, and the upper or outer edge 'of'th'e guide-tongue which-enters the creasebet'w een the plies at such seam; these relatively yielding guiding elements engaging the work-in such-manner as to" insure its proper direction to the st tchingm'echanism "operator whereby the guide rendered subwith little or no assistance'on the part "of the 'stantially self-acting. This self-acting characteristic of'the device is due tog-the guiding ridge or edge extending the direction of Specification of Letters Patent. it

' The class ofstitching mechanism preferably employed comprises two reciprocating needles spaced apart sufficiently to penetrate the extreme edges of themarginal portions of fabricor embrace the same, as-may be de.-. sired, combined with looper mechanism for interlooping with the needle threads a looperor covering thread overlying the said-marginalportions of fabric;

I merging into the forward extremity of the 18 obviously facilitatesthe descent of the spring-plate portion 17", which enters the worlcguiding channel between the wings 15 and sustains the tongue in a plane intermediate the guideeedges 15 of said wings.

From the drawing it will thus be seen that the guide-rib or tongue 18 has an upwardly directed separating edge 18 indicated at the right of Figs. 2 and 5 which merges into a downwardly inclined gulderidge or edge 18 extending in the direction of feed toward the presser-foot. The upwardly directed edge 18 separates or parts the margins of the material as they advance toward the needles. The guiding ridge or edge 18 is parallel to the edges 15 of the lateralwings 15, and these parallel edges control the passage of the material to the stitching point and insure travel of the uniting seam-in a direction midway between the needles. The length of the guide-ridge or edge is such that hand guiding assistance is not required from the operator to centralize the uniting seam between the needles.

As represented in Fig. 2, the attachment plate 12 is recessed to receive the detentspring 19 which bears upon the under face of the slide-plate 13 to maintain the guide in position. a

In the use of the attachment, the two plies of fabric a and Z) are opened out on opposite sides of the uniting seam and their marginal portions a and b are inserted between the guiding edges 15 of the wings 15 and within the work-guiding channel with the'operative edge 18 of the guide-tongue 18 en tered in the crease between them, as represented in Flg. 4;.

The resilience of the spring sustaining plate17 serves to press the guide-tongue 18 within the crease at the uniting seam with the opposite faces of the plies at such scam in contact with the guiding edges 15" of the wings 15, while the plate 17 serves asa yielding bottom for the channel to deflect the marginal portions (4 and b of the fabrics'outwardly, so that in passing beneath the presser-foot the seam is effectively flattened out-before penetration by the needles. The downward inclination of the guidingredge 18' of the tongue work to the level of the throat-plate so as 1 to pass easily beneath the upturned forward portion of the presser-foot.

It will be observed that the lateral wings to afford work-free guiding openings or slots communicating laterally w1.ththe eX- terior of the guide to embrace the marginal portions of the overlapping plies of the material adjacent the uniting seam, the intermediate plate or tongue serving as a divider for such marginal portions which are laterally flared to form grooves upon 0pposite sides of the seam having walls which are yieldingly maintained in engagement with the laterally spaced edges of the other blades under the resiliency of the supporting plate 17 by which the blade 18 is sustained. I

The needle-thread loops may be connected together on the lower face of the work by means of the covering looper-thread c, or they may be locked in the Work by separate threads to form independent seams in any usual or well known manner, and they may be so spaced apart as to penetrate the work either beyond or within the extreme edges of the marginal portions a and b of the fabrics.

While the embodiment represented in the accompanying drawings, is the preferable one, it will be obvious that the present improvement is susceptible of considerable modification in the form and arrangement of its parts within the scope of the invention. It is to be understood, however, that a particularly important part of the improvement is the spring-pressed feature of the guide-tongue 18 which insures the proper engagement of such tongue with the work sustained in opposition thereto by the having ancdgewise yielding guide-tongue disposed in. a plane'passing through said opening. a i p 3.
