IMPRQVEMENT IN SEWING-MACHINES.
Specification forming part of Letters Patent No. 145,687, dated December 16, 15-73; application filed August 16,1873.
To all whom it may concern:
Be it known that I, ELTON F. RICHARDSON, of Reading, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Sewing-Machines; and I do hereby declare the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.
The invention relates particularly to details of construction in the guide and presser-foot mechanism of wax-thread sewing-machines, with special reference to the better adaptation of such-machines to sewing turned shoes by stitches passing straight through the upper and my invention embodies, to a greater or less extent, the invention made by said Richardson.
In my invention I use, in connection with the G. A. Richardson tubular thread-guide, a
vertically-reciprocating awl-bar extending through said guide, a presser-foot, the shank of which extends down at the side of the thread-guide and in juxtaposition therewith,
a and an edge-guide at the foot of a tubular shank, which is inclosed within or is concentric with the thread-guide tube. I also employ, in connection with the needle, awl, and presser- I'oot, an edge-guide extending up through the work-plate, said guide being made movable up through the work-supporting surface and This guide is for the lapping edge of the sole; and for the ready introduction and removal of the work, the
' 7 guides are made vertically movable.
My invention consists in the details thus generally described.
mechanism embodying my invention. Figure 1 shows the mechanism in front elevation.
. Fig. 2 is a side elevation of it. Fig. 3 shows the work-plate and the edgeguide that extends through it.
a denotes the sewing-machine frame b, the work-plate; c, the hook-needle, working from below the plate; (I, the awl, working from above the plate. 6 denotes the thread-guide tube, having at its foot a projection, f, in which is the eye through which the thread passes. The thread-guide has a rotative movement to present the thread in position forthe needle-hook to take it; but the mechanism for imparting such rotative movement is not shown, as it forms no direct part of the present invention. The tube is stationary, except as to its rotative thread guiding movement and extending through the tube is the awl-bar i, said bar receiving its reciprocating movements .in any suitable manner, and working freely through or in the thread-guide tube to impart the requisite motions to the awl cl. Under the foot of the thread-guide tube is the presser-foot 70, having a shank, I, which lies close up to the side of the thread-guide tube until it reaches the bearing m, having then a bend uniting it to the presser-foot bar a, which slides vertically in its bearings, being pressed down by a spring, 0, and raised by a lever, 12. Encompassing or partially encompassing the awl-bar, and working between it and the thread-guide tube, is a tube or bar, q, having at its foot, or below the thread-guide tube, an extension, 1", that forms the edge-guide for the sole or lapping edge. At its upper end, the bar carries a collar, s, by means of which the edge-guide 1" may be raised by a lever, 25, a suitable spring, u, holding the guide down normally. By this construction and arrangement of the awl-bar, threadguide, presser-foot, and edgeguide mechanism, they are all so compacted that they readily enter the shoe, enabling the stitchforming line to be reached, the shoe to be moved and turned, and the mechanism to act as readily as if an awl-bar alone were'used above the work-plate. Beneath the work-plate is a spring, '0, having at its free end a projection or a roll, w, which, when the spring is free,
is pressed up through the work-plate, and forms a guide for the concealed edge, or edge of the upper, this guide, in connection with the guide a", enabling the upper and sole to be brought into such position, as they pass to the action of the awl and needle, as to preserve the equidistance of the stitching both from the edge of the sole and from the edge of the upper. Beneath the work-plate is also a wedge-shaped slide, 00, which, being pressed forward by a knob, 3 passes between the spring and plate, and presses down the spring so as to bring the guide 20 below the top surface of the work-plate. By depression of this guide and elevation of the guide a", the work may be readily introduced and withdrawn. By the general construction thus described, the uppers and soles of shoes are readily united without any lasting or previous union of the upper and sole.
I claim- 1. In combination with the rotative thread guide tube, the vertically-moving guide 7 at the foot of a tube or bar, q, working between the tube 0 and the needle-bar, substantially as shown and described.
2. In combination with the ed ge-guide r, the edge-guide or roll w, attached to the spring v beneath the work-plate, and extending up through said plate, substantially as described.
3. In combination with the edge-guide or roll w, the slide 00, for depressing the guide 20, substantially as described.
Executed this 27th day of July, A. D. 1873.
ELTON F. RICHARDSON.
