I to the thickness of the plate A. Invthe plate To all whom, it may concern:

Be it known that I, HENRY HITCHCOCK, of'

New Haven, in the county of New Haven and State of Connecticut, have invented new lmprovements in Sewing-Machi ne Gages; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a top or plan view of the guide; Fig. 2, a front edge View; Fig. 3, a transverse central section; Fig. 4, a portion of a collar to illustrate the use of the invention.

This invention relates to the construction of a gage to be applied to sewing-machines for running lines of stitches near the edge of articles as a iinish for the edge, with special reference to the manufacture of collars and like articles where an internal angle occurs in the line of stitching, such as seen in Fig. 4. This angle occurs in a collar at the front end, and is formed by the end and the tab or eX- tension for the button-hole. For straight stitching of this character a plain straight fixed guide is all that is required on the machine; but on the end as the work approaches the angle the guide stands in the way ofthe workthat is, the tab will strike the end of the guide, so that the guide must be removed before the line of stitching can extend down to the angle,

B is a transverse slot, C, which sets over a. corresponding rib, D, on the plate A, to serve as aguide for the movement of the plate B. The plate B is secured in its place by a screw, E, in the plate A, and brought to bear upon a collar, F, which collar extends over onto the surface of the plate at the edges of the slot C, and so that the plate B may be rmly held upon the plate A, as indicated in Fig. 3, but yet be adjusted thereon transversely-that is, from right to left or left to right, as the case may be-the flanged edge of the plate B being toward the needle and substantially parallel with the path of the feed. Longitudinally on the plate B, and near its working edge, is an inverted-T-shaped groove, G. Over this groove the guide H is placed, and through it a screw, d, is introduced into a nut, e, in the groove below, and so that the guide H may be clamped to the plate B. This should be done under a yielding pressure, and,as here represented, may be by the introduction of an elastic washer, f, beneath a hard washer, g, upon which the head of the screw d bears, as seen in Fig. 3, and so that the guide may be easily moved longitudinally in the groove, this groove, however, preventing its transverse movement. The outer end ofthe guide H is turned downward, as at h, into close proximity with the work-plate. This turned-down end IL is the guidingsurface against which the turn the angle, and pass ont() the mb, leaving work is to run in stitching, and it is in width that portion of the work t0 be den@ by the Op. only suilicient for a practical guide. The slot 35 erator without the guido, in the plate B permits its adjustment to the The difficulties attending the Stitching 0f right and left, so as to bring the guideH nearer t-he internal angle on collars is the same on t0 0l farther from the needle, as occasion reother articles where a like angle occurs. quiles; Whil@ the 10Ugtldil1 grow@ G Pel" 90 The object of my invention is the construction of a guide. which will act as a guide close down to the angle, and avoid the hand-guiding necessary in the common construction of mits the movement of the guide H forward and back.

Thus constructed the device is applied to the work-plate of the machine, and the guide guides, and my invention consists in the con- H adj usted the PlOPel distance from the Hee" struction of the guide,as hereinafter described, C116, HCGOldiug to the line of stitches to be run. 45 and more particularly recited in the claims. IU Fig* l: represents the lleedle- The WOIk A represents the plate, which is adapted to will pass along beneath the needle and against be secured to the work-plate of the machine, the guide H, Sly, Ullfl the DDGI angl@ 0011165 Say, by means 0f L Screw through the hole a, against the guide H. Now, were not the guide roo which may enter the usual guide-screw hole. Upon this plate A a second plate, B, is arranged, its working edge having a downwardly-projecting fla-nge, I, corresponding H movable in the longitudinal grooves G, the stitching could not be iinished to the angle without the removal of the guide; but so soon as (say, in case of a collar)the tab reaches the guide H, and would naturally stop, the operator, placing the finger upon the guide H, moves it as the work progresses until the extreme angle of the work is reached-say, as indicated in broken lines, Fig. 1. Thus the guide has been in position to govern the relation of the edge of the work to the needle to the extreme angle or turning-point. Then to turn the angle around onto the tab (in the case of a collar) the guide H is moved in the opposite direction until the work may be turned, so as to bring the guide against the tab 5 then the work will progress as before, the operator moving the guide until it is returned to its normal position, as seen in Fig. 1.

This illustration of the guide as applied to stitching the angle in the collar will be sufricient to enable those skilled in the art to stitch like internal angles in other work. In work where the line of stitching is at some distance from the edge-as in collars, cuffs, and like work-the eXtreme edge is liable to turn up against the guide and permit the work to approach the guide, so as to make the line of stilchingirregular. To avoid this turning up and hold the work dat, I apply to the guide H a transverse slide, l, which is introduced through an opening in the downward projection h, and into `it through a slot, m, in the guide a screw, n, is set, so as to hold it with sufficient friction that it may be moved out or in, and yet retain its place in either position.

In the drawings the guide is shown as thrown ont to lie over the edge of the work and lprevent its turning up, as before mentioned; but it may be drawn inward, as indicated in broken lines, Fig. 2, when not required for use.

While I prefer the plate A as a part of the attachment, it may be omitted, and the plate B applied directly to the work-plate.
