This invention relates to machines foropcrating upon blanks to impart to them a desired shape andisherein illustrated as em-' bodied in a machine for skiving counters for use in the manufacture of boots and'shoes.

In the manufacture of counters it is cus-g tomary to die out a blank of the proper outline from suitable sheet material, such as leather or fiberboard,and to bevel its margin by holding the blank in a suitably shaped matrix and moving the matrix in a path to feed the blank to, a tool, such as a'knife, which removes those portions ofthe blank projecting above the matrix. In ordento speed up machines of this type it is desirable that the blanks should automatically be delivered one by one to the matrix while the matrix is moving. 7 I

According to one feature of the invention a magazine in which the blanksare stacked and from which they are delivered'to the feeding means partakes intermittently of the movement of the feeding means. In the illustrated machine there is provided a"r0-' tary disk knife, a rotary table having in its otherwise fiat upper face a plurality of matrices, and a magazine for a stack of blanks located above the table. As a matrix moves into position beneath the magazine, a blank is delivered into the matrix and held there by suction until the matrix has fed the blank past the knife which skives it to a shape (1G1 termined by the shape ofthe matrix. In 01' der to ensure that the magazine and the matrix shall be inregister long enough to permit ready and accurate placing of a blank in thematrix, the magazine isengagedby the rotary table and moved with it"for a short distance every time a matrix comes into po sition beneath the magazine. I

It is desirable that each skived blank should be removed from its matrixand discharged from the machine. To this end, and in accordance with another feature of the in: vention, such a discharging means is provided. In the illustrated machine this takes I the form of a hollow swinging arm which is adapted to engage the blank by suction, to from the machine andjto drop the blank into a suitable receptacle.

These and other-features ofthe invention including certain detailsof construction andi combinations-of parts will be described "as embodied in an illustrated machine and pointed outin the appended claims."

This oscillation effects a shaking-or settli'rig'down of the blanks inlthe magazine. A rubber block, 32si s fixed on the frame and acts as'a bufie'rfo'r the'bellcrank lever during its return movement; A hand lever 33 is pivoted on the frame and carries a block 34.. By moving the lever about its pivot'the block may be caused to engage-the tail 26 of the pawl andswing the pawl out'of the path ofithe lugs 24 5 that the swinging, movement of the magazinemay be stopped, forexample for the purpose of loading the magazine, although the table'continuesto rotate. y I j r The rotary disk knife 35 is vcarried on the lower end of a shaft .43 which is rotatably mounted in 'a bracket fixed on the frame of the machine and is continuously driven. The shaft above the knife has fixed to it, a disk 44 between which and a collar l5 on the shaft extend rods 46arranged to throw out the skivings. The knife shaftis tilted in relation to the upper surface of the tablcso that the portion of, the edge of the knife which skivesthe blank is close to the surface of the table while its'opposite portion isslightly raised. Theknife is fixed against vertical movement, and the table may be adjusted ver tically' to determine the thickness to which the edge of the blank is skived. 1 A grinding Wheel 36 is'provided, and during the operation of the'machine the knife-is being ground continuously.

As the blank inthe matrix approaches the skiving knife it :passes under a presser an. ra'ngement consisting ofa number, of presser members 47 pivoted at 48 to air-arm 49 ex tending fromthe frame of the machine and each urged'yieldingly independently, bysuit- E able springs, about the pivot 48 down toward the table l so'as toholdthe blank down in front oft-he knife. To enable the ,blankjto beheld close to the edge ofthe knife at along a considerable part-of said edge, the presser members present a curved front, when seen from above the curvature of which conforms to that of the periphery of the knife.

At the rear of the machine is the discharg ing device consisting of the tubular arm 50 (mentioned above) which is pivotally mount: ed at 5lcon the machine frame and has a suction orifice at 52. An arm 53 integral with. the tubular arm 50 is connectedby a link 54 to an arm 55 pivoted'at 56tothe frame; and

thearm 55 hason it acurved finger 57- which is engaged alternately by rolls 581carriedon1 theunder side of thetable l to swing the arm 50 outward, the farm being returned by a isprmg (not shown), Theskived blankis thereby picked up from the matrix and held against the orifice 52 while the arm 50 is swungoutwardby the action of that roll 58 which engages the finger 57. Just as thearm 50 reaches its outermost position the suction in the arm is cut off, and the blank falls into- (not shown) at the rear of the a receptacle machlne. I

The suction is controlled by an arm 61 fixed 3 on a shaft 62, mounted beneath the rotary table in hearings in the frame, on which shaft is also fixed an arm 63 having connected to it arod 64. The arm 61 is engagedalternatee ly by the rolls 58 as the-table rotates, andthe rod 64- is connected to a slide, valve80 (Fig. 4) which allows the su'ctionto haveeffect either on the matrix at the loading station or onthe discharging device. As the matrices,

approachrespectively "the loading and the .7: discharge stations, that one of the rolls 58v which is then beneath the magazine engages the arm 61 and moves the rod 64 downward.

Such downward movement, of the rod, through thevalve, causes suction to be applied to. the discharging device which thereupon picks up the skived blank which is then beneath it. Whenthe roll 58 leaves the arm 61' and the rod 64 moves upward, suction is,

withdrawn from the discharge arm 50 and is applied to the matrix at the loading station;

and for a short time thereafter the table. and mag'azinetravel together, as has been" ex! plained, and the lowermost blank 1n the magazine is pulled down into the matrix.

When thesuction is thus applied to "the ma trix, it is cut off from the discharge device;

but the vacuum created in said device holds the blank against the suction orifice un'tilthe arm 50 is swung fully out, whereupon the vacuum is broken through a port indicated at 65. The suctionis maintained atthemaa t'rix which is beneath the magazine until the matrix nearly reaches the discharging station when-it is cut ofi by the depresslon' of the 'rod' 64 by the other roll 58 tandthevacuuni is broken by a port in the 'table below' the matrix coming'intofalineme'nt with a port' whichis'open to the atmosphere, 0 of the magazine is prevented from taking place by "When the swinging movement manipulation of the hand lever 33, the feeding of the blanks is also stopped be ause, as

hereinbefore stated, the suction is not applied to the matrix until the matrix and magazine have moved a short distance together so that,

if movement of the magazine is prevented;

some of therholes in the, matrixgwill have passed beyond the lowermostblank when the suction comes on, so that the suction is then injeffectiveto drawthe blank into the matrix; and the matrix, therefore; continuesits.
