Application filed A ril 19, 1913. Serial No. 762,175.

To all whom it may concern Be it known that I, FRED/"N. LA OHA- PELLE,21 citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvementsjn Machines for Operating on Shoe-Soles; and I do hereby declare the following to be a full, cle ar, 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 machines for operating upon the soles of shoes, and particularly to machines for preparing insoles of lasted shoes for sewing.

When the lasting operation has been completed, the leather of the insole, even though 1 it has been tempered in some prior operation, is usually hard and brittle and consequently unfit for sewing. It 'is therefore essential before the shoe ispresented to the 7 inseam or other sewing machine, for the purpose of attaohingthe upper and insole together by stitches passing through the upper and the between substance of the insole,

to temper thoroughly the between substance so that the needle will penetrate the material easily and make a clean puncture therethrough, and so that the thread will not out into the leather to any considerable extent when the stitches aredrawn taut. The insole is Often tempered by dipping the sole of the lasted shoe in water. This-is objectionable, since it often results in stainingthe lining of the shoe and the leather of the upper. It is frequently the practice 'to moisten thebetweensubstance by running a wet brush along the same, or by discharging water from a can having a tapered nozzle which the operator runs along the channel. laborious, and it is difficult to moisten the between substance thoroughly and uniformly by either of ,these last mentioned methods. During the lasting operation the channel lip of the insole is often bent down close to the body of the inso1e,;m'aking it difficult to .insertthechannel. guide of the sewing machine in the channel. The resistance of the lip when it lies down close to the body of the insole may cause the channel guide during the sewing operation to leave the base of the channel or. even to become completely disengaged from the chan These hand operations are slow and MACHINE FOR OPERATING ON SHOE-SOLES.

Specification of Letters Patent. Patented Feb, 20, 191 '7.

'is' presented to a sewing machine for attaching the upper and insole together, the

operator may thoroughly moisten the between substance of the insole quickly and easily without wetting other portions of the shoe.

Another Object of the invention is'to produce a machine'by which in one operation the between substance of the insole of a lasted shoe may be moistened and the channel lip turned out 'awayfrom the body of the insole'to prepare the shoe for subsequent sewing. operations.

With these objects in view the invention contemplates the provision of various novel and advantageous features set forth in the following description and pointed out in the claims.

The features of the invention will be readily understood from an inspection of the accompanying drawings illustrating the preferred form of the invention, and the following detailed description thereof.

In thedrawings, Figure 1 is a side elevation of a machine embodying the invention; Fig. 2 is a fragmentary view in vertical section illustratinga portion of the V mechanism for controlling the discharge of liquid through the nozzles of the wetting device; Fig. 3 is a detail view partly in horizontal section illustrating a portion of the mechanism for controlling the discharge of liquid through the nozzles of the wetting device; and Fig. 4 is a fragmentary perspective view illustrating the lip ,lifting tool, the nozzles Ofth'e wetting device, and a shoe in operating position with relation to the-tool. v

The machine illustrated in the drawings comprisesa rotary 'liplifting tool which is arranged to engage in the channel of the insole and to lift and turn back the channel lip. This tool, indicated at 1, ismounted to rotate on a substantially vertlcal sums,

and is provided with a series of flat faces which successively engage the lip with a sharp impact toset the lip in upturnedposition. The manner in which the tool engages the lip is illustrated particularly in Fig. 4i; The tool is secured in any suitable manner, as by means of a threaded shank, to the lower end of a substantially vertical rotary shaft 3 mounted to rotate in spaced bearings at and 5 in the forward end of an arm 6 on the frame of the machine. A pulley 7 is fixed to the shaft 8, and the shaft is rotated by means of a belt 8 passing about said pulley and extending rearwardly therefrom about two pulleys, one of which is shown at 9. The belt extends from the pulleys 9 about any suitable driving pulley (not shown). The tool is preferably rotated. in such a direction that the lip engaging face of the tool moves in the opposite direction from that in which the shoe is fed, so that the tool will have a marked wiping action on the lip. In the illustrated embodiment of the invention the tool-is rotated in a lefthand direction, and in the operation of the machine the shoe is fed from left to right, as indicated by the arrow in Fig. 4c.

The machine is provided with a moistening device comprising a tank 10 for the reception of any suitable moistening liquid, with which tank is connected a discharge pipe 11. This pipe extends downwardly and forwardly to a point adjacent the shaft 3, and is provided with a pair of discharge nozzles 12 and 13 arranged on opposite sides of the lip lifting tool. The end of the nozzle 12 is flattened to form a narrow mouth arranged to extend transversely to the channel when operating upon the insole. The end of the nozzle is located in advance of the tool with relation to the direction of feed, and is placed with relation to the lip lifting tool so that it discharges upon the outer face of the channel lip and the between substance adjacent thereto. The lip and the substance at the base of the lip are moistened by the liquid discharged from the nozzle 12 before the lip is acted upon by the tool, thereby enabling the tool to lift the lip more easily than if the lip were dry when it reached the tool. Since the lip is moistened when it is acted upon by the tool, the lip tends to retain its upward position after it is lifted. The nozzle 13 is arranged to the rear of the tool in the direction in which the shoe is fed, and is flattened at its ex tremity toform a narrow mouth extending parallel with the channel of the insole. The extremity of the nozzle 13 is placed with relation to the lip lifting tool so that when themachine is in operation it extends down fairly close to the bottom of the channel, and the liquiddischarged from this nozzle thoroughly moistens the base of the lip and the between substance at the bottom of the channel. The liquid discharged from the nozzle 12 upon the outside of the between substance, and the liquid discharged from the nozzle 13 within the channel, soaks into the leather and thoroughly impregnates the between substance with moisture.

It is essential for the satisfactory working of the machine that the discharge of liquid from the tank 10 through the pipe 11 be controlled so that the liquid flows through the discharge nozzles when the machine is operating upon a shoe, and that when the shoe is removed from the ma- I chine the flow of liquid through the nozzles is arrested. In presenting the various portions of the shoe to the action of the lip lifting tool and the moistening device, the operator requires the use of both hands to hold and manipulate the shoe. In the present invention, means is provided by which the operator, after placing the shoe in operating position with relation to the tool, by

a simple and convenient movement of the shoe may open the discharge outlet of the tank 10 connected with the pipe 11, and which acts when the shoe is removed to close the discharge outlet and cut ofl the supply from the discharge nozzles. In the construction illustrated, the supply tank 10 is provided with a discharge opening 14, and the flow of liquid through said opening is controlled by a valve. This valve is constructed as illustrated in Fig. 2, and com prises a head 15 which engages a suitably shaped seat formed by the wall of the discharge opening. The valve is provided with a valve stem 16 connected with the head which slides through a suitable opening in a valve casing 17 secured to the base of the supply tank, and the valve is held normally in engagement with the valve seat by a coiled spring 18 surrounding the valve stem and engaging the head 15 and the valve casing at its respective extremities. The liquid from the tank flows into the valve casing through openings 19 formed in said casing. The discharge opening 11 leads from the supply tank to a chamber formed by a housing 20, in which chamber is located a portion of the valve operating mechanism. Said mechanism comprises an arm 21 mounted on a rock shaft 22 journaled in the housing 20, the forward end of which arm engages beneath a downwardly projecting nose on the head of the valve. The shaft 22 is journaled at one extremity in a step bearing 23 formed in the housing. The other bearing 21 for said shaft is formed by a bore through the housing, and the shaft 22 extends through the bearing 24: and projects beyond said bearing outside the housing. A second arm. 25 is secured to the shaft 22 outside the housing 20, and extends forwardly over the upper end of the vertical shaft 3 which carries the lip lifting tool. In the mechanism described, by lifting the outer end of the arm 25, the

arm 21 will be raised therewith, and will lift the valve from its seat and permit the liquid to flow through the discharge opening 14 into the chamber formed by the housing 20. The discharge pipe 11 is connected with the interior of said housing. The shaft 3 is arranged for vertical movement in its bearings 4 and 5, so that when the shoe is engaged with the lower end of the tool by pressing the shoe upward or in the direction of the axis of the shaft, the shaft may be lifted vertically. The upward movement of the shaft is limited by the engagement of a stop collar 26 with the upper bearing 5 of the shaft, and the downward movement of the shaft in its bearings is limited "by the engagement of the pulley 7 with the lower bearing 4. The arm 25 is normally held by gravity in engagement with the upper end of the shaft 3. The parts are constructed and arranged so that when the shaft 3 is in its lowermost position, with the pulley 7 in engagement with'the bearing 4:,

the valve is closed and the flow of liquid through the pipe 11 is arrested.

In presenting the shoe to the machine, the operator holds the shoe with the portion of the margin of the sole at which he desires to begin the operation substantially parallel with the line between the ends of the nozzles of the wetting device, and then manipulates the shoe to. engage the tool beneath the channel lip. 'VVhen the shoe is thus engaged with the tool, by a slight upward pressure of the work against'the lower end of the tool, the shaft 3 is raised in its bearings, thereby raising the forward end of the arm 25 which is in engagement with the upper end of the shaft, and raising the arm 21 to open the valve. The operator maintains this upward pressure of the work against the lower end of the tool while manipulating the shoe to bring the different portions of the margin thereof into operating position with relation to the tool and to the nozzles of the wetting device. The upward pressure of tie shoe against the lowerend of the tool holds the tool firmly in the channel and keeps the valve of the Wetting device open so that the moistening liquid may flow freely from the nozzles during the o eration of the machine. When the lip li ting and wetting operation has been completed, and the shoe is moved downwardly to disengage it from the tool, the shaft 3 descends, thereby permitting the

arms

25 and 21 to descend, and the valve to be closed by the action of the coiled spring 18. The

liquid which is in the pipe 11 and in the discharge nozzles 12 and 13, when-the valve is closed, will be held from flowing out of the mouths of the nozzles by the pressure of the air.

While the invention has been illustrated as embodied in a machine which is designed stance of the insole of a lasted shoe, and for liftingthe lip of the insole, certain features of the invention are not limited to machines for operating upon insoles, but may be employed in treating other parts of a shoe either before or after the parts are assembled on a last.
