"Other objects and advantages of the invention .will become apparent fromthe following descrip- ZtiOl'l taken: in connection with the accompanying drawings and it will be' apparent that many" changes 'mayfbe madein the details of construction, arrangement of parts "and methodsshown and described without departing from the spirit of the invention as expressed in the accompanyin'g olaims. I, therefore, do not wish to belimited to the exact detailsfof construction, arrangementof parts "andmetho'ds shown and described,

' as thepreferred forms only have been shown by way of illustration; The usual practice in preparing the sole tion ofa-shoe'to be sewed inposition on the shoe has in thepast been as follows:

to the contour shapethereof. The sole was then removed-and a channel was formed therein at the contour-edge of the shoe,and in most-instances in the past, wasiormed by-a' handtool por- Thesole 'wasfirst secured to the shoe and out Q to the shoe in this position. The stitches were formed in the channel and were thence concealed therein by cementing the lip portion of the channel thereover. In most instances in the past this channel portion extended to the extreme peripheral edge of the sole. The undesired feature of this type of channel was that the lip portion had a tendency to work loose during the use of the shoe and curl outwardly leaving the stitches exposed.

In the past, most sewing machines formed the large or knotted portion of the stitches internally of the sole. This type of stitching only required a slight channel in which the exposed portion of the stitches could be concealed, but with the present type of sewing machines the large or knotted portion of the stitches are formed on the exposed side of the sole. This type ofstitching is believed to be more durable and efficient but is more difiicult to conceal. The channel previously used was impractical, that is, after the sole had been sewed imposition on the shoe, the lip portion could not be cemented back in its normal position in the channel. The exposed portion of the the lip portion would easily become dislodged from the channel and would curl outwardly at its free edge. This was due mostly to the fact that the lip portion could not be secured in its normal position within the channel and that the free edge of the lip portion extended to the extreme peripheral edge of the sole. Attentionis directed to the fact that with most prior art devices the channeling operation could not be performed when the solewas in fitted position on the shoe, that is, the

sole had to be removed from the shoe after it I had been fitted thereto thence channeled and thence re-fitted to the shoe and securedin position thereon. Most prior art devices were manually operated and depended upon the. skill 1 of the operator and for this reason accurate results could not be obtained. They not only required a great deal of time but also caused a great wastage .of material and did not produce satisfactory results.

To overcome the above defects the channel in this instance is not formed at the extreme peripheral edge of the sole portion of the shoe.

' A reinforcing space; is left between-the channel and the peripheral edge of the shoe so that the lip portion of the channel cannot be raised during the use of the shoe by stubbing the toe, etc.

Another feature ofthe present invention is that a groove is formed in the bottom of the channel. This groove is formed to receive the large or knottedportion of the stitches which, with the present type of sewing machines, is formed on the exposed side of the sole. This groove permits the lip portion to be secured in its normal position within the channel. This also obviates the tendency of the stitches to form a raised portion in the vicinity thereof after the said lip portion is secured within the channel. Attention is directed to the fact that this type of channel and groove permitsthe use of any type of stitchings.

Another feature of the present invention is that "this channel and groove can be formed simultaneously and to a predetermined depth and at a given distance from the peripheral edge of the sole. The depth of the channel and groove and. the position thereof with respect to the peripheral edge of the sole can be maintained throughout the forming of said channel and groove and will be uniform. The present method permits the forming of the channel and groove in the sole after it has been fitted to the shoe and does not necessitate the removing of said sole from its fittedposition on the shoe. This improved means and of securing the sole to the shoe does not only save much time but also prevents a great amount of wastage in material which has been usual with most prior art devices. Most prior art channeling devices depended solely on the skill of the operator and for this reason much difliculty was encountered in forming a uniform channel.

Another feature of the present invention is that the channeling and grooving operations can be performed simultaneously and with extreme accuracy, and can be performed on any contour shape of sole without removing the said sole from its fitted position on the shoe.

This improved means and method of preparing a sole and of securing the sole on a shoe is de-. signed, particularly for use in shoe. repair work and is accomplished in anextremely simple and. eincient manner. The new sole is first secured in position on the shoe, is then cut to the contour shape of the shoe, is then placed in the devicev embodying the invention and is channeled and grooved, the lip portion of the groove being slrnultaneously turned outwardly of the channel. It is then sewed in position on the shoe by a stitching within the groove, and the lip portion is then cementedin its normal position within the channel. This provides a very neat and durable construction.

The U shaped portion2 teruninates in a transverse bearing 3 havinga proe position in the slide bearing 2| by means of a jecting arm 4 thereon. The arm 4 is provided nwlth .a vertical bearing 5 in which is 'slidably amounted the channeling and grooving tool 6.

'The said channeling and grooving tool is atttached to the slide support by means of a lock screw '1 and is urged longitudinally of the bear- .rlng by a spring member 8.

:andgrooving tool=6 as shownin Figs. VI to VIII inclusive is formed with the cutting edge 9 which is adapted to form the channel I0 and thede- :pending arcuate shape cutting edge Ilwhich is adapted'to simultaneously form the groove I2 in tthevsole' of the shoe. The cutting tool 6 is positioned adjacent a toothed edge feed roll I3 which is secured to a shaft I 4 mounted in the bearing 3. The said toothed wheel is rotated, "by a handwheel I5 secured adjacent the opposite .end zof the shaft I4 and is adapted to feed the .so'lexof the shoe into the channeling and groovaing toolt during the channeling and grooving operation. ..A grooved disc I6 is mounted on the shaft I4 adjacent the toothed wheel I3 and is adapted to receive thewlip I! which is turned outwardly during the channeling and grooving operation. Attention is directed to the fact that the channeling and-grooving tool is reciprocally mounted between the toothed 'iwheel I3 and disc 45 .and the cutting end thereof is positioned substantially on the "vertical meridian of said .toothed-wheehwgthat isythe channeling and groovingportions oi the tool are positioned substantially .at the point where "thesaid' toothed wheel engagesthe-work. The purpose of this wconstruction is to provide means wherein the said channel .and groove will maintain aWpre-determined position relative to the edge of the sole throughout the entire groovingra'nd channeling ,operation. This position is determined by a hook e the table member I9 can be adjusted to desired bearings 33 shaped guide member I8-which is supported adiacentthe cutting, tool 6. A rotary table member -Isis"mountedbeneath the feed roll I3 to provide means for :supporting the edge .of the sole as it is fed into the cutting tool 6. The table member 48 is rotatably mountedon a slide rod which iszslidably end rotatably mounted in a slide bearing 2| on' an arm 22 to provide means bywhich position relative to the feed roll I3 and cutting tool 6; The table member IBi's rotatably mount- :ed in the slide support 20 by means of roller The arm '22 is provided with a bifurcated portion 23 which is pivoted at 24 to the "U shaped portion 2 to provide means by swhichthe table member I9 can beswung towards andaway from the feed roll 3 and cutting tool 6. A spring member 25 mounted in the hollow base -I adapted totconstantly urge the table member I! towardsthe said feed roll 3 during the op- .eration'of the machine. The hook shaped-guide The channeling member I8 is adjustably secured to the slide bearing 2I as shown in Figs. III and V, the. ad-

justment being accomplishedby simplydoosening the lock screws. 26 and moving'the guide member i8 longitudinallyof the slide bearing 2| towards and away'from the feed roll 13;. This hook shaped guide member is'm'ounted above I the table member-I9 as shown in Figs. I,=-II, III and V and is adaptedto engage the' edge of the sole as the saidsole is fed into the cuttingtool 6. This provides definite means for controlling the position at" which the channel andgroove are cut relative to the edge of the sole. The com pression of the spring member 25 is varied by tightening and loosening the compression screw 2?. t The slide support 2!]. is locked in adjusted clamp screw 28 which-is adapted to clamp the said slide rod and firmly hold it inhadjusted position. A cam lever 29 is pivoted at 30 to the slide bearing 2I to provide means for holding the rotary table I9 in a depressed position against the action of the spring member 25. This permits the sole material to be placed between the toothed wheel I3 and the edge of the rotary.

trolling the upward movementof' said table member. The cutter member 6 as previously described is slidably mounted in the vertical bearing 5 and is adapted to be urged towards the table member I9 by the spring member 8f The limit of the downward movement of the cutter member 5 is controlled by the check nuts 32 which are mounted on the upperthreaded end of the cutter support. This provides means for controlling the depth ofthe cut during the channeling and grooving operation.- The cutting tool 6 is angled upwardly from the cutting edge 9 to provide means wherein'the said cutting edge will automatically feed into the work at the start -of the channeling and grooving operation. f This angled portion also causes the lip IT to move upwardly within the grooved edge of the disc I'6. I The operation of the device is as follows:

The cutter member I5 is first adjusted to desired position relative to the edge of the feed roll I 3 by loosening and tightening the check nuts 32. The guide member I8 is then adjusted to desired position relative to the edge of the table member I9 by loosening andtightening T the screw members 26. The cam lever 29 is then operated to lower the table member I 9 to aposition wherein the edge of the sole may be placed between the edge of the table I9 and the feed roll I3 as shown in Fig. XVIII. 'The cam'lever 29is then operated to permit the table. to be urged towards the feed roll I3 by thespringmember ZB. When the work is in position betweenthe table I9 and feed roll I3 prior to the starting of the channeling and grooving operationthe cutting tool 6 is held upwardly by the work against the action of the springmember 8. This is caused by the cutter member sliding. upwardly in the vertical bearing 5. The handwheel I 5 is then rotated to cause the feed roll I3 to rotate and feed the work into the cutter 6. As the work isied into the said cutter the spring 8 and angled portion of the cutter function simultaneously to cause the said cutter to move into the work. The

I depth to which this cutter member enters the J5 said handwheel-leis rotated. In this manner .the channel is formed'completely around the sole main bodyportion 40.

'of the shoe adjacent the peripheral edge thereof and is cut to a predetermined depth. The position 'ofathe hook shaped end of the guide member l8 with respect to the cutter member 6 controls the position of the cut relative to the peripheral edge of the work.

1 Attention is directed to the fact that the sole is first mounted and fitted upon the shoe prior to the channeling and grooving operation and the channel and groove are formed adjacent the edge thereof when it is in its fitted position on the shoe. The sole is then sewed in position on the shoe by stitching in the groove i2 after which the lip portion H is cemented over the stitches as shown in Fig. XVII. As shown diagrammatically in Fig. XIX a groove may be formed in the said sole separately of the channel or the channel may be formed without the groove as shown in Fig. XX. This is accomplished by tilting the cutter member 6 as shown diagrammatically in these figures or by tilting the table member i8 if desired. In instanceswhere it is desired to tilt the cutter member the said cutter member will be mounted to rotate about the cutting end as the center ofthe pivot.

The sole channeling and grooving tool 5 as shown in Figs. VI, VII and VIII is formed from sheet material which is blanked out to form the The body portion is reduced at one end and is bent to form the cutter portion M. The cutter portion is formed with I a sharp edge 42 and is angled upwardly along the line A-A from said edge to provide means for lifting the lip 51 which is formed on the sole during the channeling an dgrooving operation. This upwardly angled portion is depressed centrally at 43 to form the hollow grooving cutter -l I. The said grooving cutter is provided with a mediate its ends to provide means by which it can be interchangeably secured in operative position on the machine.

The sole channeling and grooving tool shown in Figs. X, 'XI and XII is formed in a similarmanner to that shown in Figs. VI, VII and VIII with the exception of the grooving cutter i i. In this instance the grooving cutter is formed by drilling a hole l'l' in the angled portion and sharpening the edge 48. I

During the forming of the groove the material which is cut from the solepasses" through the opening 41.

From the foregoing description it will be seen that'I have provided simple, efiicient and economical means for carrying out all of the objects of the invention and that I have provided ready and facile means and method wherein the said channeling and grooving operations may be performed simultaneously or independently of each other.
