Clark, Beverly, Mass., assignor to United Shoe Machinery Corporation, Flemington, N. 1., a corporation .of New Jersey Application December 18, 1951, Serial N 0. 262,227

1 Claim. (Cl. 101-41) Thisinvention .relates to machines for operating upon "shoe insoles and it is ihereindisclosed as embodied in a machine for making reference marks upon an insole to establish the location of theqheelbreast line as a guide for the performanceof subsequent operations. For examples of machines having :breast line marking devices, reference may be :had to United States Letters Patent No. 1,113,544 granted October 1-3, 1914, in the name of Miller ,Cook, Jr., and also .to United States Letters Patent No. 2,699,110, granted January 11, 1955, upon myapplication,and:reference ..may be had also to my copending application Serial No. 250,762 filed October 10, 1951.

Machines of the type disclosed in saidLetters Patent and .copending application are known as lip cutting and scoring machines and are usually equipped with lip cutting knives, centering gages, and .devices for. impressing size and width marks upon a sole. In order to simplify the :followingidisclosure, any-showing of .such knives and centering gages will be omittedherefrom.

In some types of work it is desirable to provide reference marks indicating the position of the breast line not only upon .the .grain surface of the insole but also upon the flesh surface. It is customary to mark the breast line on the grain surface by indentations known as score marks; if, however, indentations are made in the flesh surface they are apt to be :lost to sight in the loose texture of the leather, or at least to be too inconspicuous to be of help in guiding subsequentoperations.

An object of the invention is to provide means for applying a conspicuous mark to the flesh surface of an insole and a suitable mark in register therewith on the grain surfaceto establish the .locationof the heel breast line. The mark on the flesh surface is preferably a plainly visible ink mark, and conveniently a composite mark having spacedportions; and the mark on'the grain surface is preferably an indentation or line of indentations, known as ascore mark, extending transversely of the-insole. The two marks should be in register with .each other longitudinally of the insole, i. e., thetransverse (with respect to the insole) center line of the-composite ink mark and the corresponding center line of .the score mark should coincide, except for the separation occasioned by the,

thickness of the insole; thus, if the two transverse center lines of the marks are at equal distances from the toe end of the insole, or from the heel end (by which the position of the insole is usually gaged), the two marks will be in register longitudinally of the insole. The illustrated machine is arranged for presentation of the insole grain surface down; the indentations are applied to the under or grain surface and the more conspicuous ink mark to the upper or flesh surface.

In accordance with the above stated object, a feature of the invention resides in the provision of a work table and a marking tool associated therewith for supporting and marking the under surface of an insole, in combination with a second marking tool and a presser which are engageable with the upper surface of the insole, the presser serving to press the insole directly against the first- 2,726,600 Patented Dec. .13, .1955

Referring .to .Eig. l, the Work-engaging instrumentalities .of the illustrated machine which comprise the subject matter ofthe present invention .consistof a work table 20, a marking .device .22 and an indenting tool 24. Other work-engaging.instrumentalities -.which may be included in the machine consist of a heel end gage 26, a;size.marking .die 28, a width marking die 30, and pressers 32 and 34 cooperating with the .dies 28 and 30 respectively. Although machines of the type illustrated herein are:com monly equipped with lip cuttingknives and coordinated centering gages, any showing of such membershas been omitted from the present disclosure in the intereshof clarity.

The marking devicei2'2 'andthe pressers32 'and 34are carried by a head or carrier 36 which constitutes .the forward end-portion .of a rocking :frame138 :p ivotally supported by trunnions 40 journaled in the frame of the machine. Trunnioned in the rear portion of the frame 38 is a block 42 through which is threaded a rod 44. R0- tatably attached to lower end of the rod 44 is a bracket 46 which is integral with an eccentric strap 48. In driving engagement with the strap 48 is an eccentric 49 on a shaft 50 which is journaled in bearings in the machine frame and driven by any suitable source of power. Secured on the upper end of the rod 44 is a knob 52 to facilitate turning for the purpose of adjusting the rocking 3 a plurality of teeth for marking a line of indentations upon the under surface of a work piece. These teeth, together with bar 58, constitute the indenting tool 24.

The heel end gage 26 can be adjusted forwardly and rearwardly of the machine by a cam 60 secured upon a shaft 62 which is turned by a hand wheel 64. Secured upon the shaft 62 is a wheel 66 which carries a plurality of the size marking dies 28. The width marking dies 30 are carried by a bar 68 which is mounted for transverse sliding movement in a recess formed in the work table 20. The arrangement just described for adjusting the heel end gage and for bringing selected width and size marking dies into operative position are well known in the art.

The marking device 22, as shown in Figs. 2 to 5, inclusive, comprises a cylindrical metal holder or tube 70 in the lower portion of which is formed a bore 72 of large diameter for holding an ink marker 74 consisting of a cylindrical plug of absorbent felt for holding a supply of ink. The upper portion of the holder or tube 70 is drilled and tapped for threaded engagement with a presser rod 76 extending axially through the holder 70. A lock nut 78 secures the rod 76 in a desired position of adjustment in the holder 70. The ink marker 74, which has a central opening to receive the rod 76, extends down through the lower open end of the holder 70, and tapers to a squared-01f lower end portion 80 shaped to print a composite ink mark substantially in the form of a discontinuous rectangle, as shown in Fig. 6. It will be noted that the presser 76, at its lower or operative end, is positioned between, or is embraced by, the spaced work-engaging portions of the ink marker 74. A longitudinal duct 82 extends through the holder 70 from the top of the bore 72 to the upper end of the holder 70 and serves as a vent to permit the escape of air, thus expediting the absorption by the marker 74 of ink from a container (not shown).

Clamped upon the upper end of the holder 70 by a screw 84 is a split block 86. Threaded down through the block 86 is a screw 88, the lower end of which engages the upper surface of the head 36 to determine the desired position of heightwise adjustment of the holder 70. A pin 90 extending up from the head 36 is embraced by a pair of ears on the block 86 to determine the rotational position of the block 86 about the axis of the holder 70. Before the clamping screw 84 is tightened, the holder 70 should be turned to bring the long axis of the rectangular printing surface 80 into transverse relation to the machine. The felt ink marker 74 fits tightly enough within the bore 72 to prevent its undesired rotation. A setscrew 92 (Fig. 1) secures the holder 70 in the position determined by the screw 88 and the pin 90. When the head 36 descends to bring the marking surface 80 and the rod 76 into contact with a workpiece, the point of intersection of the axis of the holder 70 with the surface of the workpiece is directly over the line of the indenting teeth 24.

In the operation of the machine as so far described, the depression of the head 36 will bring the operative end 80 of the ink marker 74 down to imprint upon the flesh surface of an insole S the composite mark shown in Fig. 6 while, at the same time, the rod 76 will press the insole against the teeth 24 of the score marking tool 58 to impress into the grain surface of the insole S the indented line, comprising two indentations, shown in Fig. 7. The transverse center line of the ink mark shown in Fig. 6 is indicated by a dot-dash line XX, and the transverse center line of the indentations shown in Fig. 7 is indicated by the dot-dash line XX. On the insole S, the line XX will be directly over the line XX', and separated therefrom only by the thickness of the material. It is evident from the above description, or from an inspection of Fig. 1, that the ink mark shown in Fig. 6 and the indented line shown in Fig. 7 will be in register with each other longitudinally of the insole.

In Figs. 8 and 9 are shown an ink marker 94 having a lower end portion different in shape from that of the ink marker 74. The ink marker 94 terminates at its lower end in two fiat-surfaced ridges 96 which imprint upon the flesh surface of an insole S the composite mark shown in Fig. 10, while the rod 76 presses the insole against the teeth to form in the grain surface a line of indentations as shown in Fig. 11. The transverse center lines of the marks shown on Figs. 10 and 11 are indicated by the dot-dash lines YY and Y--Y' respectively. On the insole S, these lines will be separated only by the thickness of the material, and will therefore be register with each other longitudinally of the insole.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

In a machine for operating upon shoe soles, a work table for supporting a sole by engagement with the under surface thereof, an indenting tool supported in fixed relation to the work table and extending above the sole supporting surface thereof for engagement with the under surface of the sole, a tube having an open end, an absorbent felt ink marker carried within the tube for holding a supply of ink and extending from the open end of the tube for engagement with the upper surface of the sole, a presser carried axially within the tube and surrounded by the ink marker, said presser extending from the open end of the tube for engagement with the upper surface of the sole at a locality between and adjacent to localities engageable with the ink marker, a carrier for the tube, and operating means for depressing the carrier to bring the ink marker and the presser down upon the upper surface of the sole to cause the presser to press the sole directly against the indenting tool and thereby to cause an indentation to be impressed into the under surface of the sole, said operating means serving at the same time to cause the ink marker to print upon the upper surface of the sole a mark which is in register with the indentation on the under surface.
