EDGE GAUGE FOR CHANNELING MACHINES Filed March 22, 1938 Patented Nov. 14, 1939 UNITED STATES EDGE GAUGE FOR CHANNELING MACHINES William R. Bolton, Chicago, Ill., assigner to United Shoe Machinery Corporation, Borough of Flemington, N. J., a corporation of New Jersey Application March 22,

13 Claims.

This invention relates to improvements in gauging devices for shoe machines and is illus trated as embodied in an edge gauge mechanism suitable for use in a channeling machine intended for operating upon so-called orthopedic insoles. v

Orthopedic insoles, so-called, are made with lateral extensions or wings at their inside shank portions or with extensions at both the inside and outside shank portions of the insoles, and in the manufacture of shoes having such .insoles the extensions or wings are laid back or molded against the sides of the lasts so that they will serve in the finished shoes to support the arches of the feet.

Edge gauges of channeling machines are commonly adjustable to produce a feather of varying width. For example, the feather may be 2/16 of an inch wide at the outside ball, -fe of an inch at the toe and inside ball and sof an inch at the shank; however, the adjustments provided for are of such relatively small variations of width that they cannot be used to care for the wide extensions to be encountered at the Shanks of orthopedic insoles. Accordingly, some means must be provided for removing the edge gauge from the path of the extension or wing while channeling in the shank section of this type of insole. To this end United States Letters Patent No. 1,482,140, granted January 29, 1924 on the application of E. E. Orr, discloses a treadle-controlled adjustable edge gauge which is adapted to be adjusted to three positions to vary the Width of feather and also to be moved to a fourth position where the gauge is lowered below the surface of the work support and out of the path of the extension. The edge gauge disclosed in that patent is provided with the customary limiting stops for indicating the three positions of the edge gauge used in channeling non-orthopedic insoles, These limiting stops arrest the movement of the edge gauge in three dierent positions and as a treadle transmits movement in only two directions, i. e., up and down, and hence is subject to only two limits or stops, the Orr machine is provided with two separate treadle mechansms for operating the edge gauge. Inasmuch as many channeling machines now on the market are provided with several treadle mechanisms for controlling dien ent elements of the machine, such for example, as the work support and the means for varying the length of the feed stroke of a selected knife, the addition of two more treadles creates a condition which is necessarily confusing to an operator.

It is an object of the present invention to provide an improved edge gauge operating mechanism which is simple and efficient in operation and in which a single control member is 1938, Serial N0. 197,436

utilized to adjust the gauge relatively tothe cutting knives to regulate the width of the feather that is being cut by the knives and also to control automatically heightwise movement of the edge gauge with respect to the work upon movement of the edge gauge to a predetermined position of adjustment. As herein illustrated in a machine for channeling insoles, this invention may be recognized in the combination of a work support, an adjustable edge gaugelocated adjacent to the Work support and arranged to overlie the work support in certain positions of adjustment and a manually operable control member which is adapted to adjust vthe edge gauge transversely to the line of feed, and also to control the heightwise movement of the edge gauge with respect to the work upon movement of the edge gauge to a predetermined position of adjustment With the above and other objects in view the invention will now be described with reference to the accompanying drawing and will be pointed out in the appended claims.

in the drawing,

Fig. 1 is a plan view of a portion of a channeling machine showing the improved edge gauge construction;

Fig. 2 is a View in elevation of the mechanism shown in Fig. 1 with the edge gauge in its lowered position-wherein it is located below the surface of thework support; and

Fig. 3 is a view in elevation similar to Fig. 2 with certain parts broken away showing the edge gauge in its elevated position.

Referring to the drawing, the invention is therein shown as embodied in a machine of the type disclosed in United States Letters Patent No. 984,773, granted February 2l., 1911 upon the application of W. C. Meyer. The illustrated machine comprises a rotary work support lil, a channeling knife I2 for cutting obliquely into the substance of an insole Ii so as to form a channel and an inner lip, an edge-slitting knife i6 for cutting inwardly from the edge of the insole in a plane parallel to the face of the sole to form an outer lip and a feather, and presser gauges I8 and 20 to limit the depth to which the knives enter the work. The machine is further provided with an adjustable slide 22 which is mounted in a guideway 2li located below the plane of the table lli. The slide 22 has a laterally eX- tending head portion 23 which has a groove therein in which is slidably mounted the depending shank 25 of an edge gauge 2t. The edge gauge 26 is normally biased downwardly into engagement with the head 23, in which position it will be located below the surface of the work support, by a spring 28 which is connected at one end to the edge gauge 26 and at the other end to a pin 2Q extending from the slide. The

slide 22 is moved relatively to the work support to move the gauge 26 transversely of the line of feed by a segmental gear 3l) which meshes with gear teeth formed in the side of the slide 22, and which is fast to the upper end of a rock shaft 32 journaled in a bracket 36. rihe lower end of the rock shaft 32 is connected to a crank arm 36 having a forked end which receives a block 38 pivoted to a rotatably mounted disk ci@ having Va depending spindlev which is journaled in a bracket 42. One extreme position of the gauge is determined by a pin "il which is carried by the disk 40 and projects into a recess i3 in the bracket `4t2, and the other extreme position of the gauge is determined by a pin 5i which also proljects into the recess 43 and is carried by a collar 39 clamped to the disk d6. Connected to the ing a latch l5 thereon for determining the intermediate positions of the edge gauge by engagement with stops on the bracket ft2 and a collar 31 clamped to the bracket F42. rihe latch together with the pin 'i depending from the disk 4U and the` pin lli extending inwardly from the collar 39 determine the various positions or" the edge gauge in a manner similar to the corresponding latch 2li and pinsl i9 and 22 in United States Letters Patent No. 1,030,802, granted June 25, 1912, upon the application of F. E. Bertrand, which shows a four position gauge adjusting mechanism for adjusting an odge gauge in a machine of the type disclosed in the patent to Meyer No. 984,773 referred to above. The brackets 3d and dil are attached to a horizontal projection Q6 on the work support slide. Operation of the hand lever lll rotates the Il@ which in turn rotates the lever 3% and gear Sil to move the slide relatively to the work support Ill.

The edge gauge is raised from an out of the way position below the surface of the work support where it is in engagement with the head 33 to an operating position above the surface or the work support by a lever ist iulcrumed upon a pin 49 secured in the arm 3e. The lever it has an end portion 5l which is disposed below the edge gauge shank 25 and is curved so as to underlie the shank throughout the range of movement of the arm 315. Formed upon the other end of the lever t8 at a locality adjacent to the disk 4G is a cam surface $3 which is adapted to be engaged by a cam surface :"5 formed upon a cam plate 50 fast to a block 52 attached to the disk Ml. Upon engagement of the cam surface 55 with the cam surface 53, the lever lil is rotated in a clockwise direction about its pivot, as viewed in Fig. 3, raising the edge gauge above the surface of the work support. The cam plate extends over that segment of the disk ttl which corresponds to the positions of the gauge when regulating the channeling of regular insoles thus holding the gauge in its raised work engaging position throughout that range of movement but terminates short of the portion of the disk which corresponds to the position to which the edge gauge is moved by the lever llt when a tab portion such as l5 o the illustrated insole is encountered, thus permitting the gauge to be moved down-f wardly under the urging of the spring 23 to enable the tab portion to pass over the gauge.

In channeling an orthopedic insole in the illustrated machine, the gauge 2S is adjusted to the three selected gauging positions in the usual manner by the lever Ml while the outer shank and ball portions are being operated upon. When the tab portion is reached, the hand lever is moved to a fourth position, with the result that the cam plate is moved from above the lever 48 allowing the latter to ltilt in a counterclockwise direction and the gauge 26 to drop below the level of the work support, thereby enabling the tab to pass over the gauge as the inner shank portion is channeled in the usual manner.

It is evident from the above description, that by placing the means for raising and lowering the edge gauge under the control of the hand lever which adjusts the edge gauge transversely of the lineof feed, applicant has greatly simplined the control oi the edge gauge, as in operating a machine equipped with an improved gauge mechanism built in accordance with the teachings of this application, all that an operator need do to control the gauge is to shift the conventional hand lever through the usual positions when channeling portions of an insole where the edge is not obstructed by a tab and when a tab portion is encountered, he need only move the hand lever to another position where the gauge will be automatically lowered out of the path of the tab permitting that portion of the insole to be channeled.
