INSOLE-TEMPERING DEVICE.

To all whom it may concern.

Be it known that I, NORMAN J. NICHOL- SON, a citizen of the United States, residing at Revere, in the county of Sufiolk and State of Massachusetts, have invented an Improvement in Insole-Tempering Devices, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the draw ings representing like parts.

The invention to be hereinafter described relates to devices for tempering insoles and more particularly to such devices for thus treating the channel of insoles prior to securing the upper, welt, and insole together.

As well known by those skilled in the art it is usual to wet or temper the channel of insoles in order to facilitate the passage of the fastening means by which the upper,

welt, and insole are secured together. This is preferably done after the insole and upper have been assembled on the last in order that when subjected to the action of the Welter the parts shall be in proper tempered condition. One means heretofore employed has been a squirt can or brush or like device in the hands of an operative, but this has been objectionable not only because the channel would not be uniformly supplied with the tempering liquid, but through haste or carelessness the upper would often be wet and consequently injured. Attempts have also been made to equip the Welter with a channel moistening device, but this causes objectionable crowding of mechanism at the stitching point and where the moistening device is controlled in its action by the machine, as has been the case, the tempering liquid has not responded with suflicient promptness, so that at the commencement of the sewing operation the channel would not be tempered; moreover, when thus supplied the tempering liquid has not sufficient time to act upon or temper the leather before the needle seeks to penetrate.

With these general considerations in mind, the aims and purposes of the present invention are to provide a hand operated device for tempering or moistening the channel of insoles, which shall be simple in Specification of Letters Patent.

construction, efiective in operation, and whereby the channel will be uniformly tempered without danger of wetting the upper of the shoe, all as will hereinafter appear from the description and accompanying drawings of one form of the invention, which in its true scope is defined by the claims.

In the drawings: Figure l is a diagrammatic view showing the manner of hand manipulation of the invention in moistening the channels of shoe soles; Fig. 2 is a central transverse section of the end portion of the moistening device, taken on the line 22, Fig. 3. Fig. 3 is a section on the line 33, Fig. 2; Fig. 4 is a section through the hand portion of the instrument on the line M, Fig. 1; and Fig. 5 is a side view of the moistening device detached.

As indicated in part by Fig. 1, a suitable tank 1 may be provided for holding the desired tempering liquid, which may be water, if preferred. Connected to the tank is a flexible hose 2 by which the liquid therein may be directed to the moistening device through the tubular metal stem 3. The moistening device preferably consists of a metal tubular piece 3 having a downturned end 4 to which is connected the nozzle 5. It is desirable that the nozzle 5 be detachable from the moistening device 3 for purposes of cleaning and repair, and as one form of means to this end, it is preferably connected thereto by suitable screw threads 6.

Below the screw threaded connection between the end 4 of the moistening device and the nozzle 5, the latter is provided with a chamber 7 which terminates at its lower end in a smaller opening or passageway 8 through which passes the stem 9 of a closure valve, the head 10 of which is adapted to be seated on the shoulder 11 at the lower portion of the chamber 7 to close the passageway 8 to the passage of moisture through the moistening device. From the construction thus far described it will be apparent that if the stem 9 of the valve in the lower end of the nozzle, which normally projects below the end of the nozzle as indicated in Fig. 5, be pushed inward, the head 10 of the valve will be unseated or raised from the shoulder 11 of the nozzle whereupon liquid is free to pass through the nozzle and the passageway 8 as will be obvious. Ordinarily the pressure of liquid which fills the moistening device 3 and bears upon the head 10 of the valve, will be sufficient to keep the valve seated to prevent passage of liquid through the nozzle; but as an additional means to this end a spring 12 may, if desired, be interposed between the head 10 ofthe valve and the shoulder 13 formed by the end of the portion 4 of the moistening device. The lower end 14, Fig. 2, of the nozzle 5 is preferably reduced in size and made circular, as indicated in Fig. 3 and on this circular portion of the nozzle is mounted the plow 15 which is free to rotate on the end of the nozzle as clearly indicated in Fig. 5. As one practical means of connectingthe plow 15 to the end of the nozzle 5 the present invention contemplates the circu'lar recess 16 formed on the lower end of the nozzle which is adapted to be engaged by the end portion of a screw plug 17, the construction being such that while the part 17 maintains the plow 15 on the end of the nozzle, it does not obstruct free rotati've movement of the plow on the end of the nozzle.

'As well known by those skilled in the art the insoles S have a channel lip 18 formed thereon, and said lip is upturned prior to the action of the welter. It is liable to be down-turned into the channel by coming in contact with exterior objects and in order that it may be properly upturned by the end of the nozzle as the latter is moved along the channel of an insole, the plow 15 is provided, and is preferably of the shape indicated by Fig. 3, so that as the nozzle end is moved in the channel of the insole toward the toe portion thereof, the plow 15 will properly guide the end of the nozzle and, should the channel lip be downturned at any point the plow 15 will serve to raise the channel lip and prevent the end of the nozzle from escaping from the channel. As the end of the nozzle moves about the insole channel and approaches the portions of the channel where the contour of the insole changes, as at the toe, the plow 15 will readily swivel around the end of the nozzle and accurately guide the nozzle in its movement about the toe portion and other parts of the channel.

The insoles and uppers assembled on the lasts are supported in any desired form of rack with the soles S uppermost as indicated in Fig. 1, wherein a convenient form of rack 19 is indicated in part, the supporting portions 20 of which may be preferably so formed that they will support the assembled p'arts without danger of the shoe moving 'endwise or becoming disengaged in the through the flexible connection 2 into the moistening device 3, and inasmuch as the moistening device has the downturned end portion 4: carrying the nozzle, it is desirable that the handle be formed non-circular in cross section as indicated "in Fig. 4, whereby the operative by grasping the handle firmly may prevent the moistening device 3 from falling over laterally one way or the. other while he pushes it around the channel of the insole as indicated in Fig. 1.

From the construction described as one practical form of the invention, it will be apparent that the channel of insoles maybe properly tempered or moistened without the necessity of the operative taking the shoes from the rack.

In operation the operative grasps the handle 21, as indicated by dotted lines in Fig. 1, and inserts the nozzle portion of the moistening device in the channel along the heel portion of the insole. The weight of the moistening device itself is usually suflicient to push the stem 9 of the valve upward in the nozzle and to unseat the head 10 of the valve in order that liquid may pass through the. end of the nozzle from the channel. He may, however, give sufficient pressure to the moistening device to force the stem 9 upward in the nozzle and unseat the head 10 of the valve and thereafter push the moistening device along the channel of the insole around the toe and back again, as indicated in Fig. 1, during which time liquid will freely pass through the end of the nozzle and the channel of the insole be uniformly and properlv tempered. As the operative removes the moistening device from contact with the insole the pressure of the liquid on the head 10 of the valve will force the valve downward and seat the head on the shoulder. 11 of the nozzle, with the nozzle, will guide the end of the nozzle along the channel of the insole through the channel moistening operation.

From the construction described it will be further noted that the flow of the tempering liquid through the nozzle is at once checked as soon as the end of the stem 9 is lifted from the channel of the insole, whereby the upper of the shoe and those adjacent thereto in the rack 19 are protected and injury thereto avoided.

Obviously, the form of the nozzle, either with or without the plow 15, and the precise form of the plow may be varied in the true scope of the invention as definitely pointed out by the claims.
