SPECIFICATION forming part of Letters Patent N 0. 447,729, dated March 3,1891.

Application filed March 29 1887- Serial No. 232,848- (No model.)

To all whom it may concern:

Be it known that I, GEORGE S. HILL, of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Sewing-Machine-Needle Guides, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has forits object to provide a sewing-machine with a guide for the needle or needles which pass through it, the said needle-guide serving to steady the needle or needles and maintain them in true vertical position to enter the material at right angles to its surface and be incorrect position to co-operate with the stitch-forming device below the bed-plate.

The invention consists in the combination, in a sewing-machine, of a presser-bar and its foot or roller with a guide having the movement of the presser-bar, and constructed of a piece of metal bent essentially at right angles and projecting from the presser-bar into the path of the needles, and having needle-holes at one end and at its other end attached to the presser-bar at a height that will keep it out of contact with the material being sewed while serving to stay the needles at the point of greatest strain upon them in The provision of a hole in the guide for each needle enables eachneedle as the needle-bar is depressed to pass through the hole of the guide in its path before entering the material, and in such cases, as when thick or stiff material is being stitched, as in vamping boots and shoes, such a guide effectually servesto steady the needles, preventing them from being sprun bent, or turned toward or from each other or out of true line.

I have herein shown the needle-guide as attached to the presser-bar.

Figure 1 shows in front elevationa portion of a sewing-machine to illustrate my present invention, and Fig. 2 a top view of the presserroller and guide removed.

The needle-bar CL of any ordinary sewingmachine is constructed and arranged to receive two needles 2 3; but, if desired, it may receive only one, as usual. The presser-bar b and its foot or roller 7) are also as usual.

The guide 0, herein shown as a bent piece or strip of metal, secured to the presser-bar Z) by a screw 0, terminates at one side of the presser-foot or roller Z) just above, but not in contact with, the material where it is to be punctured by the needle. The guide 0 is provided with two recesses or holes 4 5, through which the needles 2 3 may pass, the said recesses being separated by a small portion of metal. The needles in their descent pass through the recesses or holes 4 5 and then enter the material, and as the needles penetrate the material the guide 0 will serve to prevent the needles springing or bending toward each other or out of true vertical position.

In practice, when two needles are employed in stitching heavy, thick, or stiff material, they oftentimes spring or bend toward each other or out of true vertical position, and in such kind of work the needles are often broken, while if guided and supported against lateral displacement by the guide 0, arranged as described, all tendency of such springing of the needle is overcome, the shank of the needle bearing against one side wall of the recess.

I may, if desired, only employ one needle, and consequently the guide will have a single recess.

I do not claim a presser-foot provided with one or more needle-holes, the presser resting upon the material, as I am aware that said device is old.

I claim In a sewing-machine, the presser-bar and its presser-foot or roller, combined with the vertically-reciprocating needle-guide 0, constructed of a piece of metal bent essentially at right angles, and thus projectingfrom the presser-bar into the path of the needle, and having the needle-holes 4 5 at one end and secured at its other end to the presser-bar 5 at a height that will keep it out of contact with the material being sewed, while serving to stay the needles at the point of greatest strain upon them in entering the material to be sewed, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

enonen s. HILL.
