GAUGE Charles T. Stackpole, Worcester, Mass. Application April 22, 1937, Serial No. 138,409 2 Claims. (Cl. 112—136) This invention relates to a gauge for a sewing Hi. When it is in the vertical position, as shown, machine and is adapted particularly for com mercial sewing machines for sewing leather or the it is in the operative position and these two balls like, although capable of use for sewing machines hold it in that position up against the stop I'l. Of course, the gauge can be turned to the left, as in general. The principal objects of the invention are to indicated in dotted lines, where it is well out of the way of the machine and the operator. This provide a guide gauge on the front or outside of the head of the sewing machine; to provide for is done by simply swinging it on its pivot l8, sewing on the machine straight along the gauge overcoming the yielding resistance of one of the 10 at a predetermined distance therefrom and to balls IS. The ball at the right will then engage the side of the upper end 23 of this gauge and provide a construction of gauge which can be hold ,it there in the inclined position shown. swung to the left hand so as to get it out of the Thus, the operator can move it to the left and way when it is not in use, and to provide a con leave it there while placing a new piece of Work struction especially adapted for post machines, 15 although applicable to machines of any general on the post, threading the needle, or performing any other usual operation. It is held in vertical type. position so that there is no danger of its getting Other objects and advantages of the invention out of that position accidentally. will appear hereinafter. This constitutes a very simple and inexpensive Reference is to be had to the accompanying guide gauge which will remain in operative posi 20 drawing, in which Fig. 1 is a side view, partly in section, of a post tion under all ordinary conditions so that the sewing machine with a preferred embodiment of work can be manipulated and the operator can give all of her attention to it. It can be swung this invention applied thereto, and Fig. 2 is a front view of the same showing the out to the side and left there without any further attention while the operator is changing the work 25 outward swing of. the gauge in dotted lines. and performing other operations that have to be The invention is shown as applied to a machine comprising a post ID for the support of the work done while the machine is not running. Having thus described my invention and the and a sewing head of the usual type. The work advantages thereof, I do not wish to be limited to is supported on the post ID in such position that the details herein disclosed, otherwise than as set 30 the needle l2 will sew a seam at a constant dis tance from the edge of the work, such distance forth in the claims, but what I claim is: 30 1. As an article of manufacture, a guide gauge being controlled by the gauge. In order to pro for a sewing machine comprising a plate adapted vide this guide gauge on the front or the outside of the machine and space it a proper distance to be ?xed on the head of the machine, a pivot stud carried by said plate, a gauge pivotally 35 from the front of the head, a plate I3 is secured on the front plate ll of the head by means of mounted on said pivot stud and adapted to hang 35 down vertically in operative position, a pair of the screws I4. The plate 13 has a front plane surface Hi. It is spring balls adapted to engage opposite sides of also provided with two spring balls l6 spaced the gauge to hold it in vertical position or to yield to allow the gauge to be swung on its pivot 40 apart. These balls, of course, will yield but the to one side of its operative position until one edge 40 spring will project them so that, under ordinary engages the spring ball on the other side, where~ circumstances, they perform the desired function. by the guide will be held by that spring ball in This plate I3 also has a stop l1. On‘a pivot screw a position away from the work. l8 which screws into the plate I3 is plvotally 45 mounted the gauge I9 and it can be swung on its pivot by means of a handle 20, also project ing out of the front of the machine. This gauge is provided with a shelf 2| and with a lip 22 thereon which passes over the work. The vertical 50 surface of a downwardly projecting toe 24 con stitutes the gauge and also the guide for the edge of the work on the post. This material of the work may have a straight edge or curved but it is moved on the post I 0 in contact with the gauge 55 24 and guided thereby throughout its length. The top of. the gauge I9 is formed of a width at 23 equal to the space between the spring balls 2. As an article of. manufacture, a guide gauge for a sewing machine comprising a plate adapted to be ?xed on the head of the machine, a pivot stud carried by said plate, a gauge pivotally mounted on said pivot stud and adapted to hang down vertically in operative position, a spring ball adapted to engage one side of the gauge to hold it in vertical position or to yield to allow the gauge to be swung on its pivot to the left side of its operative position until the opposite edge en gages the spring ball, whereby the guide will be held by the spring ball in a position away from 55 the work.
