To all whom it may concern.-

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of l\lassachusetts,l1ave invented certain new and useful Improvements in Lip Turning and Slitting Machines; 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.

In the manufacture of boots and shoes when a lipped insole is used it has been heretofore the practice to slash or slit the outer side of the lip particularly along the shank, to avoid the stiffness which would otherwise be imparted to the sole by the turning up of the lip. In so far as I am at present advised of the state of the art the operation of slashing or slitting the lip, as above stated, has been performed by hand before the lip has been turned up and set by a lip-turning machine.

The present invention consists in providing mechanism whereby the slashing or slitting operation above referred to may be performed and in combining such mechanism with lipturning devices to produce a machine for simultaneously performing the operations of turning the lip and slashing or slitting the same.

The preferred form of the present invention is illustrated in the accompanying drawings, so much only of the machine being shown as is necessary for the illustration of my improvement, in which- Figure 1 is a side elevation. Fig.2isaplan. Fig. 3 is a partial side elevation of the other side. Fig. 4 is a partial front elevation, and Fig. 5 is an under side plan of the lip-turning tool.

Similar letters of reference designate corresponding parts throughout the several views.

The rotating work-support A, the bearing a therefor and the means for rotating it, the feed-wheel B, the inclined shaft b, upon the upper end of which the feed-wheel is mounted, the bearing b therefor, the means for rotating the feed-wheel, the lever O for supporting the presser-foot, the shaft 0, upon which the lever is mounted, the means for actuating the same, the slide D, the guide cl therefor, the means for actuating the slide, and the framework of the machine all may be and preferably are the same as shown and described in my copending application filed October 14, 1897, Serial No. 655,194, for which reason further de= script-ion herein is deemed unnecessary.

E represents the lip-turning tool, (shown in detailin Fig. 5,) which consists of a forwardlyprojecting portion (2, which may be termed the plow, and the rearwardly-extending supporting portion 6, by which it is adapted to be supported upon a stationary part of the machine. A recess 0 is formed in the under side of the lip-turner, shaped to receive the feed-wheel B, as shown. It is desirable that provision be made for adjusting the lip-turner toward and from the work and vertically,and for this purpose in the machine of the drawings I have shown the supporting portion 9 of the lip-turner as provided with a longitudinal slot (2 through which passes the screw e by means of which the tool is fastened to a bracket 6 Upon the under side of the supporting portion of the lip-turner may be provided a longitudinal groove c, adapted to be engaged by a corresponding tongue 6 in the upperface of the bracket e so that when the screw e is loosened and the lip-turner is moved to adjust the same and the screw 6 is again screwed down the lip-turner will assume its proper position and be securely held therein under the working stresses of operation. For securing vertical adjustment of the lip-turner I have provided the bracket 6 with a vertical slot 6 through which passes the cap-bolt e, which enters the side of the bearing 1) for the feed-wheel shaft, and the rear side of the bracket 6 may be grooved at e and engaged by a corresponding tongue 6 formed on the boss e on the side of the bearing 1), so as to secure the bracket rigidly in place. As the rotating work-support A and the feed-wheel B draw the insole into the machine the thin edge'of the plow enters the cut in the edge of the sole and turns the lip as it passes the plow.

F represents the lip-setting tool, which as the sole is fed along acts to impart the proper set to the lip of the sole. For this purpose the lip-setting tool is arranged to impart to the fiber of the lip, and more particularly to the base of said lip, short, sharp,- and rapidlydelivered blows, whereby the fiber of the base of the lip is compacted in the position it is desired that it shall retain.

To secure the above-suggested results in the machine of the drawings, the lip-setting tool is arranged to be reciprocated toward and from the outside of the lip and preferably in an inclined direction, so that the tool may act upon the lip at its base, as shown. For this purpose the lip-setting tool F is mounted upon the end of the slide D, arranged to reciprocate in the guide (I, as hereinbefore described. The lip-setting tool F is secured by a screwf to the reduced forward end d of the slide D and is preferably held from displacement thereon by a tongue (Z on the side of the reduced forward end thereof, which engages a corresponding groove f on the side of the lip-setting tool F. Provision is made for longitudinal adjustment of the lip-setting tool F by making a slot 1 therethrough to receive the screw f, by which the tool is secured to the slide D. The rounded lip-setting face f of the lip-setting tool is designed to engage and hammer the lip to force the same into the desired position, as above described. Projecting forwardly from the front of the lip-setting tool F and at the side thereof which engages the work after the face f is the lip-folding nose f", which at each reciprocation of the tool engages the lip and presses the same backward at an angle to the surface of the sole.

Lip-slitting mechanism is provided to form a series of transverse slashes or slits in the outer edge and side of the lip, and my invention contemplates the use of any suitable means for that purpose. I have illustrated in the accompanying drawings the preferred form of lip-slitting mechanism. On the side of the lip-setting tool F opposite the lip-folding nose f is mounted in a longitudinal inclined slot f thereof the lip-slitting knife f, the edge of which projects outwardly from the lip-setting face f a short distance, and which is adapted at each reciprocation of the slide D to cut a diagonal slit through the extreme outer-edge and side of the lip. The knife is secured in the lip-setting tool by means of a screw f the head of which enters a hole in the side of the tool and engages directly with the knife, being screwed into the threaded hole beyond the knife, and the knife is made with a longitudinal slot f therein to receive the screw f, by which means the knife may be adjusted to vary the depth of the cut itis to make or to compensate for wear of the edge thereof.

In order to hold the insole in position upon the work-support A and to withstand the thrust of the 1ip-setting face f and lip-slitting knife f", hereinafter described, of the lip setting and slitting mechanism against the lip of the insole, the machine of the drawings is provided with a presser-foot G, which is arranged to grip the insole within the lip and force the same down against the surface of the work-support A, thus clamping the same at the time the lip-setting tool and the slitting-knife come into contact with the lip. The presser-foot G is the same as in the machine of the former application, except that its rear side is provided with a slot g to receive the edge of the lip-slitting knife f. Now while, as before stated, the lever O for supporting the presser-foot G is the same as in the machine of my former application, the fact that the knife is designed to cut into the slot g of the presser-foot requires that the latter be deprived of the slight lateral movement of which it was made capable in the machine of my former application, to accomplish which result the lever C, instead of being mounted upon the shaft 0 to move laterally, is held from lateral movement thereon by engagement of the forked arms 0' closely with the opposite arms of the bearing in which the shaft 0 is mounted.

In order to prevent the lip from following the lip-setting tool when it retreats from engagement with the lip, I have provided a lipretaining tool, under which the lip passes as it moves away from the lip-setting tool. For this purpose in the machine of the drawings I have provided on the left of the lip-setting tool -F a lip-retaining tool II, mounted upon a f0rwardly-extending projection d on the guide (1 and secured thereto by means of a screw h, which passes down through the slot h in the shank of the lip-retaining tool and engages a screw-threaded hole in the projection d and preferably held from displacement thereon by the tongue 7 extending downwardly from the under side of the lipretaining tool, which engages a corresponding groove d in the upper surface of the projection (1 The lip-retaining tool H is provided with a forwardly-extending retainingnose 71, the lower face 7L5 of which is a short distance above and parallel to or at an angle with the upper surface of the work-support, depending upon the angle to which it is desired to turn the lip with relation to the sole.

In the operation of the machine of the drawin gs the insole, which has been previously cut around its edge, is placed in position above the work-support A, with the plow of the lipturner E and the edge of the feed-wheel B inserted in the cut. The upper flap formed by such out, being the lip of the insole, rests against the plow c of the lip-turner, and the under flap, forming'the feather, rests upon the work-support, which rises under the action of the spring and grips the feather of the insole between the upper surface of the worksupport and the feed-wheel. A rotation of the work-support and feed-wheel feeds the insole, causing the plow of the lip-turner to turn up or raise the lip, which is then acted upon by the lip-setting tool F and given a series of rapid blows to set and shape the same and by the lip-slitting knife to slit the extreme outer edge and side thereof, whereafter the lip passes underneath the lip-retain ing tool and is held at the desired angle with the surface of the sole, all as has been fully described.

While I have described my improved lipsetting mechanism as combined with the lipturning means, I do not consider my invention as necessarily requiring the use of lipturning means, as it will be understood that myinvention contemplates, broadly, the combinations set forth in the following claims, which I desire to secure by Letters Patent of the United States:

1. The combination with a work-support, of a reciprocating lip-slitting tool and means for actuating said tool to successively cut transverse slashes or slits in the edge of the lip, substantially as described. I

2. In a lip turning and slitting machine, the combination with a work-support, of a lip-turning means and lip-slitting mechanism,

substantially as described.

3. The combination with means for supporting and feeding the work, of independent lip-slitting mechanism to out a series of transverse slashes or slits in the edge of the lip, substantially as described.

4. In a lip turning and slitting machine, the combination with means for supporting and feeding the work, of lip-turning means and lip-slitting mechanism to out a series of transverse slashes or slits in the edge of the lip, substantially as described.

5. In a lip turning and slitting machine, the combination with means for supporting the Work, of lip-turningmeans, lip-setting tool, and lip-slitting mechanism to cut a series of transverse slashes or slits in the edge of the lip, substantially as described.

6.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. HADAWAY.
