To al?, whom it may concern:

Be it known that I, JOSEPH E. THAYER, a citizen of the United States, residing at West Bridgewater, in the county of Plymouth and State of Massachusetts, have 'invented certain' new and useful Improvements in Channeling-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.

' The invention relates to channeling or to rounding and channeling machines such as are used in thegmanufacture of boots and shoes. v

The invention is intended more especially as an im yrovementin the channeling' mechanism o the Goodyear rough rounding and channeling machine shown and described in the patent to French and Meyer, No.`

599,602, February-"22, not confined in its a 1898, although it is in'other forms of and channeling machines.

In the Goodyear machine as heretoforel for securing the knife carrier have constructed the devices channeling knife in the been so constructed and rarranged that it` has beenv necessary to remove the rotary sleeve forming the channeling justed. Withy thisr` construction,

ing knife has been volved considerable' lossL of also been ldifficult to .secure the proper justnient of the blade of the channeling knife with relation to the surface of the sole supporting sleeve, the sleeve is removed To this ehd one feature lof the invention` 7 I'contemplates the .provision in a Imachine y, A:ipi'ovided Witha porting sleeve, of knife clamping devices plication to this machine, but may be ein odied with advantage 1 channeling or roundingl the sole support whenever knife is to be removed or adi therefore, g the removal or adjustment ofthe chaiinelinconvenient and has inl time. It has adowing to the factI that; or out of Working rei lation to the blade when the adjustment is f Llmifei carrierpnd sole s upextending longitudinally through the sleeve, so that the sleeve does not interfere with the manipulation o-f the knife holding devices. With this construction the sole supporting sleeve may be so arranged that it periphery underlies the blade of the channeling knife to lirmly and accurately position the sole at the point of operation of the knife, without in any wise interfering with the manipulation of the knife holding devices. This enables the channeling knife to be quickly and convenientlyf removed or adjusted. It also enables an accurate adjustment of the knife blade with rebe readily secured, since the surface of the support remains in position during the adjustment of the knife blade relative to it. This feature of the invention 'in its broader Vaspects contemplates the provision of any suitable construction and arrangement of knife holding devices which extend throughthe :sole supporting sleeve into position to be manipulated without the removal or displacement of the sleeve.

In the simplest and' most the invention which I have yet devised, the knife holding devices comprise a knife holding groove or socket in the knife carrier, one side of which is formed by a head or plate at the upper end of a bolt which passes through the sole supporting sleeve and is provided with abinding nut located below the sleeve where it may be convenient-ly manipulated by ,the operator.

Further features of the invention relate to an improved construction and arrangement of the channel knife carrier and its actuating devices whereby the channelingknife mayeither be thrown out of operation during the rounding of the forepart of a shoe, or may be securely held in position to channel the forepart in accordance with the character of the work to be performed upon the machine.

' The various features of the invention will i be readily understood from an inspection of theaccompanying drawings, and the following detailed `description ofthe construction shown therein. f

In vthe drawings Figure' 1 is a side elevation lof so much of a rough rounding and channeling machine asi-Vis necessary to show the application of the passent improvements ellicient form of lation to the surface of the sole support to CJD Clt

thereto, the parts being shown in position with the channeling knife thrown out of action; Fig. 2 is a partial elevation showing the channeling mechanism with the parts in position for the channeling knife tocut a channel lin the Ysole;` Fig. 3 is a vertical sectional.' view Athrough the channeling mechanism, the section being taken on line l-3, Fig. 6; Fig. 4 is a plan View of the parts shown in Fig. 3; Fig. 5 is a partial ser-.tional view on line 5, Fig. 4; Fig. 6 is a sectional plan view on line 6 6, Fig. 3; and Fig. 7 is a sectional plan view on line 7 7, Fig. 3.

in the machine shown in the drawings, 1 indicates the trimming knife, 2 the work support or crease gage, 3 the feed plate, 4 the forepart gage, and 5 the vertically mov able slide'foi' the channeling` knife, all of which parts have the .same construction and mode of operation as the Corresponding parts in the Goodyear machine above referred to. Y

vin the present machine the channel knife carrier consists of a spindle 6 provided at.

its upper end with an enlargement or head 7 and with a thin plate or flange 8. The spindle is mounted in a bearing 9 on the slide5, and the plate 8 is provided with a concentric groove 10 engaging a segmental rib on the upper face of the slide 5. The

reely on the spindle 6 of the knife car- "ier, and its upper end surrounds the head of the carrierand lies close to the under le of the plate 8. The shank 12 of the limnel knifetits in a groove in the upper ice of the plate 8, and the blade 12 of the knife extends down over the upper end of the sleeve, so that the sole of the shoe held` inst the sleeve is firmly supported at point of operation of the channeling The knife is firmly clamped in the by a clamping bolt 13 which extends the spindle 6 andl is provided at '-1 up.; er end with a head 14 lying within .in the plate 8. The side 15 of the 'n the plate 8, and the opposing side the bolt head 14, are undercut to form a .1e-tail socket for the shank of the chanknife, which is beveled on its opposides to tit the socket. The bolt 13 is luf.

= Vlwid/ed at its lower end with a washer 16' i 1d a clamping nut- 1'7 for engaging the of the spindle 6 and drawing the the bolt ldown against the shank of the channeling knife. When the nut is tig tened the head of the bolt acts to force the shank of the knife laterally against the side 15 of the groove in the plate 8, and thus nrmly clamps the knife in position in the. carrier. llVhen the knife .is to vbe removed or adjusted the nut 17 may be readily loosened without disturbing the sole supporting sleeve 11, and the blade ofthe knife engages a roll 2O mounted on the slide.

ole supporting sleeve 11 is mounted to turn- .neling knife should be thrown out of action may be accurately positioned withrelation to the surface of 'the sleeve 11, to secure the desired depth'of channel'.

Incasesthe sole of the shoev is to be channeled about the forepart'as well as through the'shank, it is desirable that the channel be .nearer the edge of the sole around the forepart than it is in the shank. The variation in the position of the channel with relation to the edge of the sole is secured in the machine shown by raising and lowering the knife' carrying slide 5 through devices corresponding in construction `and op' eration to the devices for raising and lowering the channeling knife slide in the Goodyear macliine'above referred to. These devices comprise a rock shaft 18 mounted in ythe support for the slide 5 and connected with the slide by a. slotted arm 19 which lever 21 is secured to the end of the shaft 18, and-vis arranged to be .engaged by a shoe 22 on the lower end of apes-rin 23 secured to the lever 24 which carriesthe forepart gage 4. Theend of. the lever f 21 is held in engagement. with the shoe 22;v by a spring 25. ll'hen the forepart 'gage-is brought down into position to engage theshoe the lever 21 is depressed to raise the knife carrying slide 5 so that the channeling knife is brought into position to cut the channel nearer to the edge of tl'ie's'oi'e dring the time that the forepart gage isin-operation.. Then the forepart gage is raised' in passing' from the forcpart on ,to theshank, the lever 21 moves in the opposite Vdirf'fc-tion' to lower the knife carrying slide, so that the channel is cut at a greater distance from the edge of the sole in operating upon the shank.

- vIn doing certain classes of work the chanin passing from the shank on to the fore part, and should be again thrown in to action in passing from the forepa'rt" on to thefshank, so that the sole of the shoe operated'tnnm will be channeled through the shank, but will not be channeled -about the forepart, In the present construction the channeling knife is rendered inoperativewhen the forepart gage is brought into operation, and is 115 .rendered active when the fore-mrt gage is thrown ont of operation, through devices which have provision for rendering them inactive' when the' 'foi-apart is to be channeled, and means are provided for 'holding 120 the channeling knife in fixed position when these devices are rendered inactive. in the construction shown these devices 'comprise an arm 26 secured to the spindle 6V of the knife carrier below the. ybearing 9 throngh 125 which rocking movements may be imparted to the carrier rto move the channeling knife into or out of Aposition to act upon the sole of the shoe held againstthe 'sole supporting. sleeve 1l. The arm 26 carries a rectangular 130 block 27 which is mounted to turn freely upon a stud 28 secured in the arm. This rectangular block engages a slot in one end of a lever 29 which is pivotally supported upon a. stud 30 vsecured in a plate 31 on the lower end of the slide 5. The lever 29 is provided with a locking bolt 32 which extends up through a segmental'slot 33 in the late 31, and is provided at its upper end wit a head 34 overlying the plate.v The lower end ofl the bolt carries a thumb nut 35 which may be tightened to firmly clamp the lever to the plate 31, or mav be loosened to allow the lever to swing freely upon the pivotstud 30. The other end of thelever 29 is'provided with 'a split socket 36 in which a. stud 37 is removably held by a clampingy bolt 38 and thumb nut39. The stud 37 carries a rectangular block 40 which is free to turn on the stud. The lever 21 is provided with a bearing 41 extending below the shaft 18, and carrying a spindle 42 which is provided at its lower end with a slotted plate 43 which engages the block 40. The lever 21 is secured to the rock shaft 18 by means of a splitbearingb44 which may be contracted by a clamping olt 45 to secure the lever rig" idly to the' shaft. The clamping bolt inay however be loosened so thatf'the lever` will turn idly on the shaft. Y

When the channeling knife is to be thrown out of operation Vin passing from the shank to the forepart, and into operation in passing from the forepart to the shank, the clamping bolt 45 is loosened so that the lever 2l may turn freely on the shaft 18. The slide 5 may also be firmly clamped against vertical movement at this time'by tightening the gib screws 46. The clamping bolt 32 will also be loosened. When the parts are thus adjusted the channelin knife'will be held in the position indicate in Fig. 2, so that it will actto 'channel the sole while operating through the shank. When the forepart gage 4. is brought down against the shoe in passing from the shank to the forepart., the-lever 21 Awill be rocked, and

through the connections described ywill rock l theknife carrier,y thus movin the channeling knife intothe position in icated Iin Fig. 1, where it will not act upon the sole held against the sole support. When thev forel part gage is raised in passing from the forepart to the shank, the spring 25 will rock'the lever 21 in the opposite direction, thus returning the channeling knife to o erative position so that it will channel t e sole through the shank.

In case the forepart o f the shoe is to be channeled as well as the shank, the knife carrier will be moved into the position indicated in Fig. 2, and the thumb nut V35 will be tightened to clamp the lever 29 toy the plate 31, so that the channeling knife will be rmly held againstdisplaceint.- The thumb auf. se wiii be ioosened, and the sind 37 and block l0 will be removed, thus rendering the connections through which the lchanneling knife is thrown into and out of action inactive. The clamping bolt 45 will also be tightened so that the leverv21 is firmly secured to the rock shaft 18, and the gib Screws 46 will be loosened to enable the slide 5 to be moved vertically as the forepart gage is moved into and out cf operation.

While it is preferred to employ the specie constructionand arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential, except so far as set forth in the claims, and may be varied and modified without departing from the invention.
