AUSTIN D. RHODES, OF WALTI- IATJI, MASSACHUSETTS, ASSIGNOR TO AMERICAN LACIN'G HOOK 00., A CORPGRATION OF NEW J EBSEY.

GAGE FOR POSITIONING SI-IEET MATERIAL.

Specification of Letters Patent.

Patented Jan. 20, 1920.

To all whom it may concern.

Be it known that I, AUSTIN D. RHoDEs, a citizen of the United States, residing at Waltham, in the county of Middlescx and State of Massachusetts, have invented new and useful Improvements in Gages for Positioning Sheet Material, of which the following is a specification.

This invention relates to a gage for positioning the edge of the upper of a boot or shoe preparatory to having lacing hooks or eyelets set therein.

In setting lacing studs, eyelets or hooks in the uppers of boots and shoes, it is desirable to have a gage against which the upper edge of the upper may be placed in order to locate said edge in the proper position relatively to the lacing hook or eyelet setting instrumentalities in setting the first hook or eyelet in the upper and also to have said gage capable of being easily and automatically removed from the path of the upper as it is fed forward after the lacing hook has been set.

To these ends the invention consists of a gage of the character hereinafter set forth in the specification and particularly pointed out in the claims and furthermore of the combination of the gage with a presser foot and work-support and means to move the presser foot away from the work-support or vice versa.

Referring to the drawings:

Figure 1 is a plan view of my improved presser foot and gage.

Fig. 2 is a front elevation of the same showing a portion of a work-support in connection therewith, the presser foot being shown in its elevated position and a section of an upper shown in position relatively to the gage.

Fig. 3 is a front elevation similar to Fig. 2, with the presser foot in its lowered position and clamping the upper to the work support.

Fig. 1 is a -t of Fig. 2.

In the drawings the presser foot land work support are similar in their design and mode of operation to the work-support and presser foot illustrated and described in Letters Patent issued to Arthur R. Havener November 29, 1910, No. 977,090, Ma-

detail section taken on line chine for setting lacing hooks, to which reference may be had for the mechanism whereby the presser foot is raised and lowered.

out the several views of the drawings.

In the drawings, 10 is a presser foot clamped at one end thereof to a vertical rod 11 to which a reciprocatory motion is imparted by suitable mechanism such as that described and shown in said patent.

A gage 12 is pivoted at 13 to a bracket 14 and the bracket is is fastened to the body portion of the presser foot by a screw 15 which projects through a slot 16 provided in said bracket and has screw-threaded engagement with the body portion of the presser foot. The is preferably formed of a thin piece of sheet metal which projects into a slot 17 in the bracket 14: and consists of an arm 18 with a finger 19 proj ecting downwardly from its free end. The finger 19 projects downwardly through a slot 20 in the bracket let and through a slot 21 in the body portion of the presser foot.

The front edge 22 of the finger 19 which forms a portion of the gage 12 has a notch Like numerals refer to like parts through- 23 therein and a portion 24: of the front edge 22 projects downwardly and forwardly from the work contacting surface 25 of the presser foot when the presser foot is raised as illustrated in Fig. 2, and a portion 26 of the front edge of said gage extends downwardly and rearwardly from the lower end of the portion 24; to the lowermost end 27 of the gage 12.

The general operation and manner of using the presser foot gage hereinbefore specifically described and illustrated in Figs. 1 to 4 of the drawings is as follows: Assuming A-A to be the center line of the setting instrumentalities, the gage is adjusted longitudinally of the slot 21 until the front edge of the gage, where it intersects the work contacting surface 25 of the presser foot, is at the correct distance from the center line A-A or at the desired distance from the top of the edge of the shoe upper to the desired center of the first lacing hook to be set therein, the operator holds the upper 28 in the position illustrated in Fig. 2, the presser foot being at this time raised with the upper edge of the upper contacting with the front edge of the gage adjacent to the work contacting surface 25 of the presser foot.

At this time the lower most end 27 of the gage 12 rests upon the upper surface of the work contacting surface 25-} of a worksupport 30 and as the press-er foot is lowered from the position illustrated in Fig. 2 to the position illustrated in Fig. 3, in order to clamp the upper 28 between the presser foot and the work-support, the gage is pushed upwardly rocking on its pivot 13, and the parts assume the relative positions illustrated in Fig. 3, with the edge of the upper 28 resting against the part 26 of the edge 22.

In a subsequent motion of the machine, as is well known to those skilled in the art, the presser foot is raised just suilicient to take the iressure off of the u) 381 which l then automatically fed forward and the rearwardly inclined portion of the front edge of the gage allows the upper to pass toward the left, Fig. 3, and in so passing the gage will be pushed upwardly by the upper and said upper allowed to pass to its new position to receive another lacing hook or eyelet.

It will be seen that when the upper is in the position illustrated in F 2, if the operator tries to push the upper toward the left it will be impossible so to do because the edge of the upper is located between the inclined portion of the front edge gage 22 and the work contacting surface 25 of the presser foot. When the parts are in the positions illustrated in Fig. 3 and the upper is fed toward the left, the gage is lifted by the upper and passes upwardly out of line therewith.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

l. A presser foot and a gage movably mounted thereon and adapted normally to: project beneath the work contacting surface: of said presser foot, the front edge of said gage being inclined downwardly and for wardly from said work contacting surface.

A presser foot and a gage inovably mounted iereon and adapted normally to project beneath the work contacting surface of said presser foot, the front edge of said being inclined downwardly and forwardly from said work contacting surface for a portion of its length below said surface and then rearwardly and downwardly to its lowermost end.

8. A presser foot and a gage movably mounted thereon and adapted normally to project beneath the work contacting surface of said presser foot and through a slot extending longitudinally of said presser foot, the front edge of said gage being inclined downwardly and forwardly from said work contacting siirface.

A presser feet, a bracket mounted upon said presser foot and adjustable longitudinally of said presser foot and a gage movably mounted on said bracket and adapted normally to project beneath the work contacting surface'of said presser foot, the front edge said gage being inclined downhardly and forwardly from said work contacting surface.

A presser foot and a gage movably iziounted thereon and adapted normally to project beneath the work contacting surface of said presser foot, the front edge of said gage having a notch therein adjacent its lower end.

6. In combination, a work -support, a presser foot, a gage movably mounted on said presser foot and adapted normally to project beneath the work contacting surface of said presser foot and against said work support, the front edge of said gage being inclined downwardly and forwardly from said work-contacting surface and means to raise and lOWGf said presser foot.

'2'. In combination, a WOTZ-SUPPOH), a presser foot and a gage pivotally mounted upon said pr er foot and adapted nor mally to project beneath the work contacting surface of said presser foot, a portion of the front edge of said being inclined downwardly and forwardly from the work contacting surface of said presser foot and means to raise and lower said presser foot.

8. In combination, a work support, a presser foot and a gage pivotally mounted upon said presser foot and adapted normally to project beneath the work contacting surface said presser foot, a portion of the front edge of said gage being inclined downwardly and forwardly from the work contacting surface of said presser foot for a portion of its length below said surface and then rearwardly and downwardly toward the work contacting surface of said work support and means to raise and lower said presser foot.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
