l My invention yrelates to slriving machines and more particularly to a machine adapted to shave the edges of leatherV in order, that such edges may be foldedL back upon ;them- 5 selves to produce a seam no thicker than the Y body of the leather. i

I am aware that slriving machines have been in use for a number ofyears but, to the best 2 of'my knowledge, no machine has ever been 4lo produced which will sk'ive the edges of a piece of leather whose outlineis irregular.

One of the objects ofmy invention'isto provide a machine which'will skivel theV edges of a piece of leather regardless ofthe irregu `15 larity of its outline.

ln thel manufacture of certain styles of shoes, it is customary to cut holes in the leatherfand, in some cases, to place a piece of differ- -A ent colored leather behind such openings'in ..20 order to provide a contrast of color. In the better grade of shoes, itis customary to skive and fold the edges ofthe leather around these openings in order that the raw'edges of theV leather will not show and, until my 'machine 4 necessary to` do such slriving by hand.y y f v Anotherobject of my invention is to provide a machine which willskive the edges around apertures in lea-ther in order that suoli :ze edges may be folded over to forinv seams no thicker than the body of the leather.

Still another obj ect of my invention is to provide a skiving machine which willbe compact and'occupy but little bench or floor space V35 and which will be capable of producinga large quantity of work with the consumption of a comparatively small amount of'power. Y

These objects, and other advantageous ends which 'will be described hereinafter, l attain 4.0 in the following manner, reference being had to the accompanying drawings in which Figure 1 is a front'elevation, and Figure 2 a top plan view of alslrivi'ng machine embodying my invention. y

Figure 3 is an elevation of the left hand enf of the machine shown in Figures 1 and' 2, an t Figure 4 a .fragmentary sectional view,

ly exaggerated.,k v A y 'Figurer 12 is a view similar to Figure 11 but showing amethod of making a beveled skive ;`v .165 the'thickness of the leather and the tiltof the cutting ydiskbeing exaggerated.

Figure 13 showsa piece` of leather'having skived edges around .an aperture therein.

Referring now more Vin detail tothe draw-p70 ings, the machinehas a base 15, from whichy a mainframe 1.6 extends upwardly and has a U-shap'edzb'earing17 secured thereto in which n .is rotatable a shaft 18 carrying a loose pulley 19 and fixed pulleys 20 and 21 between the two 75 parts of the bearing. One end ofshaftlS ex" tends` beyondbearing 17 and hasfixed thereon a pulley 22 abutting the end of the bearing .and a beveled gear 23 abutting'the pulley.

Gear 23 meshes with a beveled gear 261 fixedso to a vertical shaft 25 rotatable in adivided bearing 26 secured to the side oflmain frame 16. YBetween the two bearing portions, apulley 27 is fixed to shaft 25 and carries a belt 28 which also engages a Vpulley 29 fixedv on, a35 spindle 30 rotatable, in a divided bearing 31.

YA cutting disl l32 issecuredto'the `lower end of spindle 30 and a collar33 is xedtoits upper end',preferably byhaving a tapered pin insertedthrough holes in the shaft andcollar-{JO Y respectively.

, A guard bear1ng-34 is journaled on spindle 30 immediately below collar, 33 and, whenl in itslowermost position, restsonI the top of bearing 3 1.v An extension135 isV forme'dfon '95 bearingV 311 and hasfan adjusting screw36 ro-A tatable therein and 'threaded into thetop of` `bearing 31.k Screw. l36'is held against axial -movement through bearing 34 by means fof a v Shoulder .37 and a Collar `3 8 disposed-at'elther 10U 84 extends and is threaded in frame 16. v Slot 83 is providedin orderthat bearing '48 and lits associated parts may be movedutwardly as will` be later described. Shaft 44 is movl able vertically in bearing `48 which is provided with a cap 85 resting on the top of shaft 44and tending to hold same in its lower position by the action of spring 79; cap 85 being held against lateral movement by fitting be- A'tween the sides of bearing 48. Itwill be noted v thatshaft44 is reduced .in diameter adj acent roller 46v and that bearing V48 and capk85 are "bored to accommodate this reduced portion so that shaft 44 is held, against axialmovement f Yrelativelyv to bearing 48 by thel shoulders thus formed on the shaft and in the bearing. abutlting each other andfbythe end of roller 46 abutting the end 86 of bearing 48. Y.

End 8.6 of bearing48 is normally in'linelwith the transverse'centerlinelof wheelg58vand its lower; edge extends below roller 46 and acts as a guide for the edge lofthe, leather which lisbet ing skived. Foot 7 8 is secured to or formed on bearing 48 so that its left .hand edgeyasxin Figure 8, coincides with end 86 and the top of foot 78, as well'vas the adjacent corner of bearing 48, is roundedv so that the leathermay fbereadi'ly led f romthe `top of foot 7 8'along end' 86 tol thecutting disk 32, as shown at 87 'in Figure 8. In order that spring79-lwill not press feed roller. 46 against tliesupporting wheel `whenfthere isV nov leather v inter- 1 posed between them, I provide a-n-eXtension 88 on bearing cap 85 andthre'ad'therethrough a thumb screw 89,1sfee Figurey 9, the end of which bears against-bearing 48,.. Ifit were not for thumb screw, 89fit would be difficult Y to` introduce leather' *betweenlfeed roller 46 and supporting wheel 58. v '1;' i As feed roller'46 must 'move vertically to allow for dierent thicknesses of leather,

-jforme'don frame16. f

Leather 76 is bentdownwardly Aalong the bearing'47 must beso mounted that itwill swivel slightly to accommodate .fthe vertical VVmovementofvshaft '44., Thisis accomplished Vby making therear end ofbearing47 cylindrical, vcutting fine threads. thereon and then screwing. the bearing into a projection 47L face 90 of supporting wheel `58 `ata point adl jacent cutting disk 321 so'that the width of the skive will be equ'altoapproximately one half-'the width'ofwheel;58..,. This isf accomplished by a U-shap'ed guide member 91'bolted to, thetop offbearing-cap 85 andy having its f. lower,portionj 92 disposed near face 90 Zof the supporting wheel. The bottom of port-ion `92` 1 istapered from the front torear and thebottorny p art ofL its c free Vend rounded, as yshown ,in Figure 9, inorderthatuthere will beno square edges to `marthe leather being skived a orto impede its progress through the mai` chinef The bolt, which. 4securesfguide member `91 Yto bearing cap 85,2 passes through a lslot ,Qintheftop ofthesguifde member, seeFigure 8, so that the distance between the end of portion 92 and face 90 of supporting wheel 58 may be varied to accommodatedifferent thicknesses ofleather.

In order that-the leather being skived will'v be kept out of contact with cutting disk 32, Y

except at the point where the skiving is done,

VIvprovide a flat guard 94adjacent theunder 32 israised or'lowered, by. means of guard side of Vdisk 82 and supported by arod 95, Y

secured to guard bearing 34 so that whenvdisk 75 bearing34 and adjusting screw 36, guard 94V will movewith it.

' When a piece of leather` fed through the machine as above described, a shaving of a width equal to the distance between face 90 and end 86 will be cut-from the leather so that, when theportion ofA leatherA bent over by guide member 91 isr raised to the same plane as the skived portion, va substantially square A shouldered skive, such as is shown inFigure 11, will be formed. In skiving they edges around an aperture in a piece of: leather, foot 78 will prevent the leather from being drawn too far into the machine and end 86 will guide the material so that a skiveis'made inv the proper location. l/ith this arrangement, the

edges of an aperture may be quickly and neatly skived regardless ofthe size or shape of the aperture, which operation has here-A tofore been impossible. f yAssuming that the machine is supplied with powerand that it is desired to skive the edges of an opening in a piece of leather, the pedal on rod 72 should be operated'to lower wheel 58, the leather inserted between wheel158 and roller 46 until the edge of the aperture can will be -cut 0E that portion ofthe leatheron if `the periphery of the wheel 58'as`itV is fed against Vdisk 32. .The operator works the leather over foot 78, keeping the portion next to disk 82 against lend 86 while allowing roller 46 and wheel 58 Vto feed the leather toward leather. i'sthin and flexible 'and can easily be distortedby the operator inwerking lsame over foot 78 and that guardk 94 deflectsfthe leather away from cuttingdisk 32k as fast as it is skived.` In this manner, the edgesof an aperture may be readily skived, regardless ,disnea It is to be `un,derstmd that the of the contour of the aperture. In skiving the louter edges of a pieceof leather,it Vis y held'agafinst entl 86 asit is fedfbetweenroller `461 and wheel 58. l

Inthis connection it is to be borne' in mind that thespace on both sides of the wheel-58 "immediatelybeneath thejdisc 32 is clear andv u'nobscured'- permittingfthe leather to be theskiving of the leather along one side of v an aperture such as is shown in Figure 13 has been completed,the leather will beprevented from advancing further by the foot 78.'

tendv tol cause theleather to beirotated-to the right (viewing'the machine as presented in Fi'gurel); This tendency is materially aided by the peculiar knurling of the roller 46 which is suchas to tend to pull the leather toward `the end or shoulder 86. This shoulder, as set forthabove, `prevents further progress of the edge being operated upon by the disc 32, but Y f after the edge has been skived the leather may L `fully turn aboutthe foot 8 for the reasons set forthabove. "The unfinished side ofthe leather is presented to the roller 46' and the leather ispres'sed downwardly over the edge of wheel58 `by the guide member 91..

l/Vith the freedoln provided asoutlined Habove,'the.leatherfmaybe turned at will by l the attendant without in any manner niarring or injuring theu leather. ln consequence, an

aperture of any shape andan Vedgehowever irregular' maybe skived without injuring the work. VAlso, owing to the tendency of the knurled roller 46 to move the edge being operated on laterally thereof toward thefend i" of the aperture to tion, and soon.

With regard'to the specific knurling of the roller 46 by whicha feed is obtained tending to maintain'the edge of the leather being i i' i skived against .theend shoulder 86',l it will be seen,by examination of Figuresl, 4, Y5 and 9 that the ridgesof the knurling are inthe` nature of spirals `46fthe courseof `which is upward toward the end 86', as viewedv from the front. In "consequence, as the roller 46 is "rotated clockwise and the wheelk 58 counterfclo'ckwise considering the rollers as viewed in Figure 3 the ridges on wheel 46 will tend to force-the vleather toward the right as viewed in Figure 1, thusre'ndering the skiving action somewhat automatic' as totheman'ltena'ncel of tapered or beveled, as shown" in Figure12,

and to attain this end I mount bearing 31 o n asupport 96 which is held in selected posi- Y. tions by means of abolt 97 passing through -a 4slot 98andbeing secured' in frame 16;

bearing: 31 being pivoted` to main frame `16 by a pin 99y disposed opposite the center line of spindlel and near. the'center of the lower half of bearing 31. By looseningbolt 97,

pin 99 and thus tilt cuttingdisk 32, relatively to supporting wheel 58, and thus allow a beveled cutfbeing taken from the edge of VVthe leather, as shown inFigure 12. f

v vBy tilting`v spindle 30, thefcenter of the cutting disk is moved from the center line of supporting wheel 58. The set screwsin gear 54 andfcollar 59 may be loosened and shaft 55 Vmoved longitudinally to bring supporting v wheel 58 into effective position relative to diskv 32.` Bolt 84 may then be loosened and 4bearing 48 moved longitudinally to bring feed roller 46 into position relative to wheel 58; pinion 45, being of 'greater widththan gear 54, does not need to be moved. While thewidth of` a square shouldered skive is determined by the distance between end 86 vofibearing148 and face 90 of wheel 58,`the

widthjof a beveled skive is also determined by the tilt of disk 32. Y As it is important that cutting disk 32 be provided with a keen edge at'all times,I pro- *107, secured to the rear facel of frame 16, and

may be rocked by means of a handle 108 formed integral with' arm106* and held in selected positions by means of a toothed member and latch arrangement 109.

When it is desired to operate emery wheel 100, handleV 108 is raised which will cause arm 106 to move outwardly and downwardly and bring pulleys 105 in engagement with belt103", thus putting tension on the belt and Acausing itto rotate pulley 104. Shaft 101 is Vmounted at an rangle to spindle 130`so that the Vedge ofthe emery wheel will grind the edge of cutting disk 32 tothe proper bevel. Emery wheel 100' may be brought into and out of Vcontact with "cutting disk 32 by means 'of an adjusting screw 110 rotatable in a support 111 which is rotatably 'mounted on shaft 101'and held against Vaxial movement vthereon by co1- lars 112' fixed toshaft 101 and'disposedat either side of support 111. Adjusting screw 110 is threaded into bearing 102 and has a collar'and a'hub disposed at either sidevof support 111 so that turning thev adjusting screw will raise or lower support 111 and conf sequently bring emery wheel 100 into or out of contact with cutting disk 32.

- While I- have described the principle of` my invention relative to particular form, itl

will be understood thatjmodicatijons may be made Without departing from .the spirit thereof, and henceI do not limitmyself to the precise construction set forth, but consider that I `am atliberty to make such changes andv alterations as fairly come within the scope .of the appended claims.
