GAUGING DEVICE.

Application filed November 5, 1917. Serial No. 200,298.

T 0 all whom it may concern:

Be it known that I, EDWARD E. ORR, a citizen of the United States, residing at Weymouth, in the county of Norfolk and State of lllassachusetts, have invented certain new and useful Improvements in Gauging Devices; and I do hereby declare 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.

This invention relates to gauging devices, and is described as embodied in the edge age mechanism of a stock-fitting machine. or purposes of explanation the invention is illustrated as embodied in the well known Goodyear insole and turn channeling machine described in the United States atents to Zachary T. French No. 453,999, une 9, 1891, and Frank E. ldeckman, No. 550,402,

November 26, 1895, and No. 644,571, March 6, 1900; although those skilled in the art will recognize that the invention may be embodied with slight mechanical changes in other types of machines.

In making shoes for wearers having flat feet it is common to rovide an insole having a shank portion wider than the forepart, which may be termed wing-shaped, the channeling cuts, however, following, as usual, the outline of the last bottom and, at the shank of the insole, cutting through the base of the two wings well within the margin of the insole. The two wings are turned against the sides of the last, when the shoe is assembled, and, after lasting, are held in such upturned position where they act as arch supports for the foot of the wearer.

While the ed e gages of stock-fitting machines such as c hanneling machines are usually adjustable to produce a varying width of feather, usually from 2/16" at the outside ball, to 3/16 at the toe and inside ball, and 4/16" at the shank, it is obvious that such adjustments cannot be used to care for the wide protuberance of an arch supporting insole which may be 1 1/2" or more at its widest point on the shank at the inside of the insole. Nor is it practical, due to the construction of many of these machines, to withdraw the edge gage a suflicient distance to entirely clear the edge of the insole when operating through the wings.

The object of the present invention is to provide improved edge gage operatin means in machines of this general type, sai means being particularly adapted to enable the operator of the machine easily to care for these wide variations, as for example in channeling arch support insoles. In accordance with this object a feature of the invention contemplates the provision of edge age operating means which will enable t e edge gage to be moved to a position where it will not engage the work, as by being dropped below the laterally projecting wings of an arch support insole when channeling the shank, but to be used in the ordinary manner when desired.

o the accomplishment of this object the invention comprises the features and combinations of parts hereinafter described and then particularly pointed out in the appended claims.

In the accompanying drawings illustrating the best form of the invention'at present known, Figure 1 is a front elevation of a commercial Goodyear insole and turn channeling machine fitted for insole work and having the present improvements applied thereto; Fig. 2 is a detail of the edge gage construction, in elevation, showing it in inactive position, below an arch supporting wing of an insole being operated upon; Fig. 3 is a rear end view of the ed e age; and Fig. 4 is a face view of a channe e arch support insole.

In the embodiment of the invention illustrated in the drawings the machine frame 5, channel and edge knives 7 and 9 with their presser ages 11 and 13, the feed wheel 15, the inso e supporting table 17, and their operating mechanism, including the crank handle 18, are all shown as being the same as in the present Goodyear insole and turn channeling machine when fitted for insole work, except that the edge knife is shaped to have a heel as shown in Fig. 2, instead of having the usual straight blade, to enable it to cut into the surface of the sole across the bases of the two laterally projecting wings.

As in said old machine the distanceof the base of the li cut, produced by the knife 9, from the e go of the sole is determined by the (position of an edge gage mounted on an e ge gage support comprising a slide 19 secured to the frame by the screw 20.,

p'essed through the slot 22, which slide may adjusted to move the edge gage across the line of feed into certain predetermined positions. In the resent construction the edge gage 21 instea of being an integral part of the edge ga slide is located at the forward end of t e slide and is carried on a separate shank 23 housed in a groove 25 formed in the under side of the slide. A pivot pin 27 holds the shank 23 in place and a sprin 29 housed in the slide 19 and bearing on 510 shank 23 at the rear of the pivot 27 normally maintains the ga e elevated sufficiently to project over t e top surface of the sole supporting table 17, as shown in Fig. 1. The bottom of the groove 25 acts as a stop to limit the upward movement of the gage under the influence of the spring 29. The usual bell-crank operating lever 31 pivoted on the frame 5 and connected to the slide 19 is actuated by a treadle (not shown) on a treadle rod 33. The treadle is normally maintained raised, with the gage 21 in its position of farthest advance toward the knives, by a spring 35 coiled on the treadle rod and confined between a collar on the rod and a flange on the frame.

The customary limiting stops are provided for the various positions of the edge gage in channelingthe usual type of welt insole. The forward position 2/16" feather, may be determined by an en agement of a lug 37 (Fig. 3), which pro ects inwardly from the rear end of the slide, with the for ward one of a pair of nuts 39 and 41 secured on a threaded pin 43 projecting from the frame. at the rear of the slide. The rear position, 4/16" feather, may be determined by an engagement of the lug 37 with the rear nut 41. A separate treadle mechanism and stop is utilized to determine the intermediate position, 3/ 16" feather, of the edge gage. To this end a lever 45 (Fig. 1) is pivoted on the connection of the treadle rod 33 with the bell-crank lever 31. One end of said lever underlies the horizontal bell-crank arm and the other end has depending therefrom a treadle rod 47 to which is attached a second treadle (not shown). This is in effect a lengthening of the horizontal arm of the belt-crank lever, effective, however, only on its downward movement since there is no spring on the treadle rod 47. A stop 49 is carried in the frame below the lever 45, which is engaged by said lever, on depressing the treadle rod 47, before the slide 19 is withdrawn far enough to engage the nut 41.

In channeling the arch support t pe of insole shown in Fig. 4, the stop 41 is backed up on the screw 43 sufliciently to permit the edge age 21 to be brought clear of the edge of t e table 17 when the treadle rod 33 is depressed, and this stop is not used to determine any! position of the insole relatively to the knives. This extended movement of the edge gage slide 19 causes the rear end of the shank 23 to engage, and be elevated by, a cam lug 51 located beneath the edge ge shank and carried by a bracket 53 a ustably secured to'the frame 5, as shown in Fig. 1. The engagement just described causes the edge age shank 23 to be tilted about its pivot 2 and consequently the edge gage 21 is depressed to a position below the under face of the insole, as shown in 'Fig. 2.

In channeling the right foot, arch support insole S shown in Fig. 4, the head carrying the knives is lifted by the usual hand lever 55, the treadle rod 33 is depressed bringing the edge gage 21 to the position of Fig. 2 and, after a'sole has been placed on the work table 17 the two knives are dropped into the insole at the point C on the outside of the heel seat. Previous to placin the insole in the machine a standard so e pattern is placed on the sole, and using the edge of the pattern as a rule, lines showing the true outline of the shank are drawn across the bases of the lateral arch supporting wings W. These lines are used as guides in channeling across the wings and, for unskilled operators, a pointer 57 for said guiding line, may be mounted on the ed e knife presser gage 13, the lower end of tl ie pointer lying just in advance of the heel of the edge knife. After channeling through the outside wing VV'the treadle rod 33 is released and .the spring 35 acts to throw the edge gage 21 up and over the table 17 in its farthest advanced position which position is maintained to about the tip line. Then the treadle rod 47 is depressed which brings the edge gage to its intermediate position, which position is maintained until the forward end of the inside wing W is reached, when the treadle rod 33 is again depressed to withdraw the gage below the wing. The guiding line marked on the insole is utilized in channeling across the base of the wing and the knives are run out of the sole as usual at D.

In channeling a left foot arch support insole, the operations are the same except that the knives are dropped in at a point on the inside of the heel seat opposite the point C on Fig. 4, the treadle rod 47 is depressed after channeling the inside wing W and released at about the tip line on the outside of the toe. and the knives are run out of the insole at the outside of the heel seat.
