AUSTIN I). RHODES, OF WALTHAM,

MASSACHUSETTS, ASSIGNOR 'I'O AMERICAN LACING HOOK (30., A CORPORATION OF NEW JERSEY.

I '0 all w from it may. concern:

Be it known that I, AUsTIN D. RHODES, a citizen of the United States, residing at VValtham, in the county of Middlesex 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 whichthe upper edge ofthe 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 hasbeen set. I

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.

This case is a. divisional case from a copending application-filed by me on July 29,

1918, for gage for positioning sheet mate-' rial, Serial No. 247,116.

Referring to the drawings:

Figure 1 is a plan view of my invention illustrating the gage mounted on aworksupport. 1

Fig. 2 is a front elevationof my invention showing the same in connection with a worksupport and presser foot, the presser foot being shown in elevated position anda portion of the upperof a boot being shown in position with its upper edge resting against the front. edge of the gage.

Fig. 8' is. a. front elevation similar toFig.

.2,,bu-t illustrating; a modified form of gage embodying my invention.

In the drawings the p'r'csse-r footand worksupport are similar in their design and mode of operation to the work-support and Specification of Letters Patent.

1918, Serial No. 247,116. Divided and this application filed November 29, 1919. Serial No. 341,535.

2, 5 is a presserfoot which is fastened to a vertical, reciprocatory rod 6; 7 is a gage pivoted at 8 to a bracket 9 which is adjustably fastened to a work-support 10 by means of a-screw 11 which projects through a slot 12 in said bracket 9 and has screw threaded engagement with the work support 10. The gage 7 has an arm 13 thereon at one end thereof which projects upwardly through a slot 1% provided in the work-support 10 and has its uppermost end 15 arranged to bear against the work contacting surface 16 of the presser foot 5. The front edge of the gage '7 has a notch 7 therein and has an inclined portion 17 which extends from the work contacting surface 18 of the worksup port 10 upwardly and forwardly and which has another inclined portion 19 which extends rearwardly to the uppermost end 15 of said gage. The gage 7 is enlarged on the opposite side of the pivot 8 from the arm 13 as at 20 to form a counterbalance.

The operation of the device hereinbefore specifically described is as follows: Assuming B-B to be the center line of the setting instrumentalities, the gage is adjusted longitudinally of the slot 12 until the front edge of the gage where it intersects the work contacting'surface 18 of the worlcsupport 10 is at the correct distance from the center line B-B or at the desired distance from thetop of the edge of the shoe upper to the desired center of the first lacing hook to be set therein. The operator hold'stheupper 21 in it clamps the work against the work-support the gage 7 will be rocked upon its pivot, the end 15 being pushed downwardly until the edgeofthe upper 21 rests against the part 19 of the front edge of the gage.

In the subsequent motion of the machine, as is well-known to those skilled in the art, the presser foot is raised just sufiiciently to take the pressure off of the upper which is then automatically fed forward and the rearwardly inclined portion 19 of the front edge of the gage allows the upper to be moved toward'the left Fig. 2 and in so pass ing, the gage will be pushed downwardly 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 Fig. 2, if the operator tries topush the upper toward the left, it will be impossible so to do, because the edge of the upper is located between the inclinedportion 17 of the front edge of the gage 7 and the work contacting surface 18 of the work-support. When the parts are in the relative positions assumed thereby when the presser foot is slightly raised to allow the upper to be fed toward the left,

the gage is pushed down by the upper and.

passes downwardly out of line therewith, because the edge of the upper will at that time be engaging the rearwardly inclined portion 19 of the front edge of the gage.

In Fig. 3 a'modified form of my invention is illustrated which is the sameas the form of my invention hereinbefore described andillustrated in Figs. 1 and 2, except that the gage 22 is not provided with a counterbalance but in-order to hold the gage upwardly with its uppermost end pressing against the presser foot, a spring 23 is at tached at one end to said-gage and at the other end to a pin 24 fast to a bracket 25.

' The operation of this form of my invention is the same as that of the form'of my invention illustrated in Figs. 1 and 2.
