GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 234,181, dated November 9, 1880.

Application filed April 12, 1880.

To all whom it may concern:

Be it known that I, JAMES F. J. GUNNING,

of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Guides for Sewing-Machines; and I do hereby declare the following, when taken in connection with the 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 1, a perspective view of my invention; Fig. 2, a top or plan view thereof; Fig. 3, a diagram illustrating use of the same.

This invention relates to an improvement in guides for sewing-machines, the object being to gage by both edges of a strip of material, one of which may be straight and the other variously curved-as, for instance, as shown in Fig. 3, where it represents a straight edge, I) the curved edge, and d the line of stitches to be made parallel with the side a.

In the usual construction the guide only operates upon one edge of the material, the material being held againstthat edge by hand, requiring the constant watchful care of the operator. In some special classes of work two guides have been arranged to work against each other, one yielding-as, for instance, in the Patent No. 164,241.

The invention whereby the object may be accomplished consistsin the construction hereinafter described, and particularly recited in theclaim.

Arepresents the stationary part of the guide. This is best made from thin sheet metal doubled to form the edge e and so as to leave a space between the doubled parts, through which the work will pass, running against the inside edge, e. Opposite this folded guide is a plate or support, B, which may be made adjustable relative to the edge e of the guide A.

C is the guide for the opposite edge of the material. This guide C is arranged on rods f extending forward from the plate B, and on which the guide C will play back and forth.

Between the guide C and plate B is a spring, D, bearing on both ends of the guide 0, tending to force it forward toward the guide A, but yet so as to allow the guide 0 to be moved (No model.)

to and from the guide A, or rocked relative to the guide A.

In order to hold the edge of the material flat and against the guide C, a groove is made in the front of the guide C, here represented as by two flanges, g h, between which the edge of the material to be sewed will run.

Supposing the straight edge of the mate- 6o rial to be sewed is run against theinner edge,

e. of the guide A, and the .curved edge against the yielding guide C, and the guide A arranged in relation to the needle so as to make the stitches in the required line, the result 6 is that the material will be pressed forward against the inner edge of the guide A, the guide C yielding forward and back to correspond to the shape of the opposite edge, yet holding it up to the work against the guide A, and the line of stitches will be run parallel to the edge of the stationary guide A; or if the line of stitches is desired to be parallel with the curved edge, then reverse the work, running the curved edge against the guide A. The adjusting-guide 0, running against the straight edge,will hold the curved edge up to its work; or both edges may be curved, still the guide C will hold the edge which is to govern the line of stitches up to the guide A. This enables the operator to run several machines for such class of work, because the work, once started, guides itself.

The spring D is here represented as a flat metal spring; but other springs may be sub- 8 stituted therefor. The guide C may also be supported otherwise than on the rods f, it only being essential that it should be supported and made automatically yielding to produce the result, as described.

I do not broadly claim a stationary guide and an adjustable guide opposed thereto, for such I am aware is not new.

1 claim- The combination of stationary guide A, 5 guide C, spring D, and supports, arranged substantially as described, whereby the said guide C is permitted to rock or be self-adjusting relatively to the said guide A, substan tially as specified.
