INS EAIlVI SHOE-SEWING MACHINE.

To all whom it may concern:

Beit known that I, ANDREW EPPLER, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements, in Inseam Shoe- Sewing Machines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an inseam shoe sewing machine and particularly to novel means for determining \the correct position for the channel guide.

In the practical use of an inseam shoe sewing machine it is often desirable to changethe position of the channel guide so that the particular kind of work to be operated upon may be held in the correct position in the machinewith relation to the va-'- .rious parts of the sewing mechanism and particularly with relation to the needle. Thus in changing from one kind of work to another, it is often desirable to adjust the point or lip of the channel guide transvcrsely of the line of feed toward or from a vertical plane passing through the axis of the needle.

The object of the present invention is to provide mea s whereby the transverse adjustment of he point or lip of the channel guide can be readily made by the operator, accurately and without any considerable loss of time.

With this object in view the present invention contemplates the provision in an inseam shoe, sewing machine of a gage mounted in the machine so as normally not to interfere with the operation of the machine or with the manipulation of the work by the operator but movable by the operator into a position to indicate the correct position for the channel guide.

The invention contemplates the use of a gage of any suitable construction mounted in an y desired manner .so asto be capable of movement by the operator into a position toindicate the correct position for the channel guide.

In ,the best form of the invention which has as yet been devised the gage consists of an arm pivot-ally mounted on the frame of the machine, in such position that normally the gage is away from the point or lip of Specification of Letters Patent.

the channel guide but can bereadily swung by the operator into close'proximity to the guide.

The present invention will be clearly understo'od from an'inspection of the accomthe gage, hereinafter described, for determining the correct position. for the channel guide, is the same in'the construction, arrangement and mode of operation of its various parts as the machinedisclosed in applicants prior application, Serial No. i47,5a2,

filed August 8, 1908.

In, the machine illustrated in the drawing 11 indicates-the curved hook needle, 2 the needle guide, 3 the awl, 4 the looper, 5 the take-up, 6 the auxiliary take-up, 7 the weltguide and 8 the back rest.

The channel guide of the machine is indicated at 9 and is secured to a block 10 mount-- ed so as to be capable of vertical adjustment on the channel guide lever 11. The channel guidelever 11 is pivotally mounted upon the feed slide 12 of the machine and is provided at its upper end with a tooth which meshes with a toothed segment or arm 13. The

toothed segment 13is secured to the inner end of a short shaft 14 journaled in a bracket on the frame of the machine and to the outer end of the shaft 14 is'secured a cam actuated arm 15. The hub.of the arm 15, which engages the shaft 14, is split as indicated in Fig.1 and the arm is secured to the shaft by means of a clamping bolt 16. By loosening this bolt the channel guide lever 11 can be moved to adjust the point or lip of the channel guide transversely of" the line'of feed and when the bolt is again tightened the channel guide is secured in its adjusted-position.

The gage to determine the correct position for the channel guide is indicated at 17 and consists of an arm pivotally mounted atone side of the machine frame and curved at its free end so as to bring'this end into the same vertical plane as the channel guide.

Ncrmallv-the arm 17 hangs in a vertical p0" is a view in front elevation partly in 65 sition as indicated by dotted lines in Fig. 1. hen in this position the arm is out of the way of the operation and does not interfere with the sewing operation. When 't is de-'- sired toiset thechannel guide for any particular class of work, the arm 17 is swung upwardly into the horizontal position indicated in Fig. 1. When in this position the surface at the outer end of the arm is directly' back of the point or lip of the channel guide, and is in a position to limit the backward movement of the guide. For certain' classes of work the channel guide will be so adjusted that its point or lip is in contact with the surface at the end of the arm 17; while for other classes of work the point or lip of the channel guide will be a short distance away from this surface. In

any event, however, the surface at the end of the arm 17 will indicate a fixed point in close proximity to the point or lip of the channel guide and thus enable the operator to set the channel guide accurately in the desired position without any appreciable loss of time. a

The preferred form of the present invention having been thus described what is claimed is 1. An inseam shoe sewing machine, having, in combination, stitch forming devices, a channel guide, mechanism for moving the adjusted.

guide toward and from the work having provision for adjustment to adjust the lip of the channelguide transversely to the direction of feed, and a movable gage arranged to be mo ed by the operator into a position to indicat the correct position for the channel guide and to be moved away from said position after the channel guide has been the direction of feed, and a movable gage arranged to be moved by the operator into a position to indicate the correct position for the'channel guide and to be moved away from said position after the channel guide has been adjusted.

ANDREW EPPLER.
