The table or plate A, its legs a. a and its standards or uprights 0/ a, cast or otherwise secured to the upper side of the table, constitute-the framework of the machine. To the uprights a, is east or otherwise fixed a long I horizontal boss or projection a in which is mounted and fixed a bar a so as to project therefrom parallel, or nearly so, with the table. The bar a is preferably made circular in cross section,and on it is mounted by means of the boss I) a curved plate B. The plate B may be adj usted'by means of the set screw b in any desired position upon the bar a Between the uprights c a. is also mounted on the shaft 0 the doubleended lever O. The lower end of the lever C is provided with a lug 0* against which the end of screw-shaft c, mounted in bearings provided for its reception within the table A, is made to work for adjusting purposes. The opposite end of the screw-shaft c is armed with a handle 0 To the top c of the lever O is fixed the curved lever or bar 0 armed at its free end with a bedding piece at, which is jointed thereto to hang over the plate B. The plate B and bedding piece (3 are curved to correspond with the contour of th boot or shoe sole as shown; the center of th radius of the plates being at d of the adjusting bar D.

The bar D is mounted horizontally, above the table, in the bearings a 0. provided for its reception in the upper part of the uprights a so as to be adjusted laterally according to the size of the boot or shoe operated upon, to per mil". of the center d being immediately, or nearly so, over the center of the curvature of the boot or shoe toe. The adjustment of the bar D is regulated by the collars d d which are'retained in position by set screws. The end 61 of bar D is bifurcated, see Fig. 25, to receive the block or axial bearing E (Figs. 26 and 27) which is mounted therein by means of studs or trunnions at d.

In the axial bearing E is mounted by means of the spindle fand nut f the inverted L shaped pendent bracket F. By mounting the bracket F (Figs. 22 and 23) by the spindlef in the axial bearing E, which in turn is jointed to the bar I) a universal joint is provided wherebythe paring tool, to be hereinafter described, may be moved in any required dire'ction.

To the bracket F is fixed the end 9 of the lever or bar G (Figs. 34 and 35), said lever being armed with a handle g (Figs. and 31) for directing and controlling the course or angle of the paring tool. The opposite end 9 of lever G is connected to a sliding part of the carriage H, of the machine, by

means of the fixings g g and link 9 (Figs. 28

and 29) to which the said fixings are jointed by the studs 9 The carriage H (Figs. 9 to 12) of the machine is provided with two uprights h h in which the rod 77/2 slides. The rod is armed at one end with a crosshead h and at the other end with a knob h for bringing it in and out of action. The rod may be kept from revolving by means of the piece 77. mounted thereon so that its lower surface will slide upon the top of the carriage. On the rod is also mounted and fixed the sleeve 72. to which is pivotally attached, by the screw b the fixing g At Figs. 1,2, 6, 9, and 12 the rod is shown in position for the paring tool to be in action, and it is kept to its work by the springs h 71 the ends of which are respectively attached to the crosshead h and to the trunnions h of the sleeve h". The rod h is held in its outward position, as shown, by a slotted catch it arranged to slide vertically on the upright h, and to pass into the notch it provided for its reception in the rod. A second notch k may also be provided in the rod for retaining it in its normal position, that is, when the paring tool is out of action.

The slide I, (Figs. '7 and 8) is provided with a cross-piece I of the shape shown at Fig. 8, which is made to extend across the table A. To the cross-piece I are fixed, at a right angle therewith, the guides 11"17 arranged to slide longitudinally on each side of the table,

as shown at Figsr2, 4 and 5. slide I is a longitudinal recess i for the purposes to be hereinafter described. To the face of the slide I is fixed a circular piece 2', around the periphery of which the semi-circular piece h (cast or otherwise fixed to the under side of the carriage H, and which is turned to fit the circular piece 11 works when the carriage has been traversed forward so as to bring the center of piece 2", under (or nearly so) the center of the toe of the boot or shoe. The circular piece 2 is provided with a stop i against which the ends h and h of the semi-circular piece it are made to work for retaining the carriage H at or about a right angle with the recess 4? as shown at Figs. 6 and 6 while the tool is paring the edge of the sole, say from the breast of the heel to the commencement of the radius of the toe and vice-versa. In order to retain the carriage II in the said position and thereby secure greater accuracy for the working of the paring tool, the end h or h of the semi-circular piece 77. is held against the stop i by a catch portion 1' of the lever 2', (Figs. 36 and 37) said catch portion being adjacent to the point at which the lever 2' is pivoted (at 2'?) to the slide I. The lever 11 is armed on its under side with a pin i which when the carriage H and slide I have traveled to nearly the position shown at Fig. 6 engages with a notch in the form of an incline cam t' formed in the plate 2' (Figs. 47 and The plate 1' is arranged to slide within In the slotted a recess t formed in the central arm of the I slide I. The plate i is fixed to the short vertical shaft J (Fig. 6) by a set screw 2' The lever 11 is locked in the position shown at Fig. 6, by the notched end t' of a tappet lever 11 (Figs. 59 and 60) pivoted to the end of the crosspiece I,at or about a right angle to the lever i )Vhen the lever t is locked by the notched end of the tappet lever 11 as shown at Fig. 6, the outer portion of the catch portion t of lever 11 will be in contact with the end h of the semi-circular piece 71 thereby holdingthe carriage H at or about a right angle to the central arm of the slide I. The paring tool to be hereinafter described is then in a position to commence paring at the waist of the boot near the breast of the heel, the catch end 17* of lever 11 being retained. against the end h by the spring i The lever 11 remains looked, as described, during the outward traverse of the slide I until the commencement of the radius of the toe is reached when the enlarged weighted end 11 of lever t comes in contact with the incline 2' (Figs. 37 and 58) fixed to the table A for raising the notched end from its contact with the lever '6 Instead of allowing the weighted end 2' of lever 01 to mount the incline when it is desired to unlock the lever i the weighted end i may be arranged to travel upon the top of a bar with an inclined end, and descend the incline for releasing purposes. In either case the Weighted end 43 may be kept in contact with the table A, or bar by a spring attached to IIO IZC

pin 43 Simultaneously with the raising of the notched end of lever "6 the cam plate 1' comes in contact with the pin i on the under side of the lever 2' and by the continued outward movement of the slide the lever i is caused by the plate 2' to turn on its pivot i and thereby move the end i away from the end h and clear ofthe semi-circular piece 71 as shown at Fig. 6 As soon as the end i is clear of the semi-circular piece, the carriage H and paring tool are free to revolve around the circular piece 2' and toe of the boot or shoe until the end h comes in contact with the stop '5 when the spring i will have returned the lever i to the position shown at Fig. 6 to permitof theinner side, that is, the side nearest to the pivot i engaging with the end h of the semi-circular piece 71 for locking the carriage H again at a right angle to the central arm of the slide I, as shown at Fig. 6, for paring. the opposite edge of the sole from the toe to the waist. Simultaneously with the releasing of the pin i the runner 2' mounted on pendent pin 1' which is screwed or otherwise fixed to the under side of carriage H, comes in contact with the inner periphery of the concentric cam K (Fig. 38) projecting from the plate K mounted on shaft J below the slotted lever L.

. The slotted leverL (Figs. and 56) forms a cam for reciprocating the slide I and rotating the carriage H. To the under side of the carriage H is fixed a plate h from which projects a pendent stud h armed with a runner 71, arranged to work in the slot Z of lever L. hen the runner h has been traversed in the slot Z to the position shown at Figs. 1 and 6 of the accompanying drawings the paring tool is prevented from moving out of the desired radius by the runners h and i being respectively in position by the end of lever L and cam K.

Motion for traversing the paring tool from the breast of the heel to and round the toe and back to the breast of the heel on the opposite side of the boot or shoe is imparted from the A winch or other handle J mounted on horizontal shaft J through spur gearing J mounted on the horizontal shafts J J, and bevel gearing J mounted on shafts J and J.

The paring tool, previously referred to and shown in detail at Figs. 40 to 54, is provided withaknife M consistingofaflat blade shaped as shown at Figs. 41 and 42 and provided with a cutting edge m The knife is fixed to the face m of the block m (Figs. 49 and 50). The block m is mounted in a carrier (Figs. 39 and 40) consisting of an angle piece m fixed to a pivot pin m. On the block at is also mounted a second block 171 (Figs. 45 and 46) provided with a notch m which passes overthe edge m which is at a right angle to the back m Of the knife M for securing the lower portion of the knife to the block m The front of the blade is chain fered to form a cutting edge m The two blocks m and m are secured in position on the angle piece m by a single bolt m The upper edge m of the knife M is secured between the plate m (Figs. A3 and 44) and welt protector m (Figs. 53 and 54) armed with a projecting lip m arranged to pass over the outer edge of the knife as shown at Fig. 6. The plates m and m are held together by pin m and set screw m and fixed to the top of block m by a set screw m the notch "m on plate m being arranged to fit into the recess m formed for its reception in the upper part of the angle plate m for more securely fixing the knife M in position. In front of the cutting edge m is mounted asole guide m" (Figs. 51 and 52) capable of adjustment vertically to the varying thicknesses of the soles by means of the set screw m; and it may also be adjusted, if required, laterally by a second set screw m ,shown in dotted lines at Fig. 19, working in a slot provided forits reception in the vertical portion of the angle plate m. Attached to or forming part of the sole guide m" is a paring regulator m This is placed slightly in the rear of the knife so that the latter will cut a shaving off the sole. The thickness of the piece m may vary from about three-sixteenths of an inch to any re- .quired thickness.

The pivot pinm is mounted and secured by set screw a in the boss, which forms an axial bearing a, of the carrier N. The carrier N is jointed at n to the lever G as shown, so as toreadily adapt itself to the varying curves of the boot or shoe.

Itwill be readily seen on reference to Figs. 1 and 3 of the drawings that the centers of the block E, the circular piece 2' when the tool is paring the toe, and that of the toe, or heel, of the boot or shoe are arranged almost in a line with each other, while as long a leverage as possible is obtained between the centers (Z and 773. Also by'mounting the paring tool as described provision is made for adapting itto the varying contours and curves of the sole.

When it is desired to take out the bit, that is to chamfer the top of the sole from the upper to its front edge, on the plate m ting edge for taking the bit out at the same time that the edge of the sole is being pared. At Figs. 17 to 19 the bit knife m is shown applied to the plate m", and arranged to take the place ofthe welt protector m that is, to perform the functions of both welt protector and bit knife.

The action of the machine for paring the edge of the forepart of the sole is as followsz-The bedding piece c is placed within the boot or shoe so that its lower surface will rest upon the inner sole, while the outside of the sole rests upon the plate B. By mounting the latter plate on the round pin a its po- 'sition will be readily adapted to thesole;

IOC

The boot, shown in dotted lines at Fig. 1, is clamped in position on the machine, with the center of the toe over the center of the circular plate 1', by the curved plate B and bedding piece 0 the requisite pressure being imparted thereto by handle 0 through screw shaft 0 which forces the end 0 of lever C outward, and the end c inward carrying with it the bar 0' for pressing the bedding piece 0 tightly onto the inner sole of the boot. The center cl is then adjusted by means of the bar D and collars d 01 so that the center d shall be approximately over the center of the too. The carriage H having been previously moved to its extreme inner position, as at Fig. (S that is, near the uprights a, in which position the carriage H will be at or about a right angle to the longitudinal axis of the bar D, and to the slide 1 and the cam lever L at or about an angle say of twenty-eight or thirty degrees (more or less) to the said slide. The paring tool is then placed in position, after the rod W has been pressed inward until the catch it is fixed in notch h, with the welt protector 'm. (or bit knife m resting upon the top of the sole, to prevent the upper coming in contact with the edge m of the knife M, and the bottom of the sole resting upon the sole guide m which has been adjusted to the thickness of the sole by screw m. The knife M commences paring at or near the breast of the heel, say at ocFig. 1, at which point the lever G will have raised the knife owing to its radial connection with bar D and axial bearing E up toits work, and it is held thereto by means of the rod 79, sleeve h, springs h fixings g g and link 9 By mounting the bar D and spindlesf, m in axial bearings, and also pivoting or jointing thebearing E, the carrier N, and fixing g as described the knife M will adapt itself to the varying curvatures of the sole. The carriage H when in this position is locked by the end h of semicircular piece 71 being held against the stop 71 by the lever as described. By connecting the carriage H with the cam lever L, by means of runner h pin it and plate h tit is caused to slide in a longitudinal direction until the commencement of the radius of the toe is reached whenever the handle J! is rotated thereby imparting a rotary motion to the cam lever L through shafts J J J and gearing J J. The carriage H remains in a locked position until the cutting edge m of the knife has been brought in 'a line with or opposite to the center of the toe, that is, at the commencement of the radius of the toe. When this point has been reached the end t of lever 1' will have traveled up the incline 2 and raised the notched end 11 of lever 11 clear of lever 2' and at the same time the inclined plate 1'" will have acted upon pin Q1 as previously described, for unlocking the carriage H and moving the lever 11 to the position shown at Fig. 6 thus permitting the carriage H to revolve on its axis 2' around the center plate 1' fixed to slide I. At the same time the runner d will have been brought in contact with cam K thereby retaining the knife in position while the toe is being pared. When the carriage H is released from its connection with lever i the cam lever L causes it to revolve round the center plate 41 until the end h of the semi-circular piece h comes in contact with the stop i during which rotation the knife will have pared the toe. As soon as the end h is against the stop 1' the inner side'of end t of lever 11 then engages with the end h of the semi-circular piece for holding the carriage H at a right angle to the slide I as shown at Fig. 6 while the opposite edge of the sole from the toe to the breastof the heel is being pared. It will thus be seen that while the shaft J and cam lever L are making half a revolution the knife M is carried completely round the edge of the forepart of the sole, that is from waist to waist, by first causing the slide I and carriage H to travel together until the knife reaches the commencement of the radius of the toe, when the carriage His released and travels alone round the toe, after which the carriage is again locked when the slide I, carriage H, and knifeM are simultaneously traversed to a position near the uprights a as at Fig. 6. During the traverse of the knife round the edge of the sole its angle is regulated and controlled by the operator by means of the handle g. When the knife has reached a point on the opposite edge of the sole to 00 the catch h is raised from notch h which releases the bar If and permits the springs 77. to return the bar to its normal position for the catch to enter notch 71 thereby withdrawing the knife from its contact with the edge of the sole.

To pare the heel which requires a wider knife than is used for the edge of the sole we proceed as follows: We use aplate B with a flat top as shown at Fig. 3, and a bar or lever G provided with a curved end is fixed to the end c) of lever O in place of the parts shown at Fig. 1. The boot, shown in dotted lines at Fig. 3, is placed with its toe toward the uprights at, its heel resting on the plate B, and clamped thereon by the curved end of lever O in a similar way to that described for Fig. 1. The knife holder m, for the heel paring tool, is pivoted to a carrier N which in turn is jointed to the lever G as previously described. The knife P, shown at Figs. 13 to 15, is fixed to the holder m by means of wedge shaped plates m m which take the place of the blocks and plates described for the sole paring tool. The wedge shaped pieces 'm m may be adjusted by the screws m 772 Instead of making the welt protector a fixture and adjusting the paring regulator m as previously described, we connect them together and arrange that they shall be capable of adjustment by means of lever O pivoted to carrier m by pin 0 The welt protector m and paring regulator m are mounted upon the rod 0' sliding in the bearings .O O and arranged so that the upper end of the rod shall work between the bifurcated end 0 of lever O. The protector m" is arranged to work on the seat of the heel, and it is retained in contact therewith by a spring 0 placed on the rod 0 between the bearing 0 and movable collar 0 The protectorm may be raised and lowered to its work by means of the lever O. A second paring regulator O to work against the top lift of the heel may also be provided when required. The paring tool is traversed round the heel in a similar manner to that described for paring the toe, but instead of using templets and a roller, the top, lift or layer of the heel is out nearly to its finished size before the heel is built and it is made to take the place of a templet, and the knife is guided round the heel by the handle g.
