Specification forming part of Letters 4Patent No. R0IL5`99 Beit known that we,ARzn B. KEITH, of N orth Bridgewater, and TIMOTHY K. REED, of East Bridgewater, all in the county of Plymouth and State of Massachusetts, have invented, jointly, Improvements in Machines for Shaving Heels upon Boots and Shoes; and we do here the following, taken in ,connection with the drawings which accompany and form part of this specification, is a description of our invention suiioient to enable those skilled in the art to practice it. t

rllhis invention relates to certain improve ments by which, when, heels a're fixed 'in po'sition upon bootsandshoes, we are enabled to shave or cut them to the proper curvilinear outline by the action of a cutter moving from ardth'e heel-seat, or vice versa, t around the en# tire curved boundary of the heel. In the drawings, Figure l represents in pering a boot or shoe to the action of the cut-ter;

ilarview of the same machine, showing a diiferent form lof jack or holder designed for the Vsame purpose.

The cutting apparatus used in this machine general form qf the letter U, the knife beingtinade in two parts hinged together in the sharp bend of the curve.' rlhis knife is atV taehed to a holderywhich holderis secured lto a cross-head which can be made to move up and down, carrying with it the knife, which cuts the superfluous leather from the outside olJihecurved part ofthe heel submitted toits operation'. The knifeholde'r is so attached to the cross-head that it may be adjusted Vto give. rake or slant 'to the rear 'part of .'The knife being in two parts hinged the tread, and devices are introduced to cause pen as it descends and because of its upward motion.

ble being guided and steadied by contact with the standards` b, the object of saidtable beine" to receive and support th `anism atv the proper heig e shoeholding mech-` ht.

The cross-head c is iitted on the standards b,

so that it can be moved upl and down thereupon, and is guided thereby,the downward movement of the crosshead being power applied vto the treadle f, nected to' thel cross-head b ward movement of the cross-head is produced by the reaction of springs h, which are compressed in the-descent ofthe cross-head.

The cutter per se it is not necessary to de scribe especially, as it is notv nov-el and was ed States Patent No. 6,095, and there described as arranged to cut heels before they were attached to boots and shoes, The cutter is represented by. ings.

' The distance to which the edge of the cutterl can be moved. downward can be limited by the adjustable nut on the end of rod p, said .rod passing through the crosspieces c, and being fixed in the cross-head e.

For 'the purpose of presenting and holding 'a boot or shoe with a rough heelupon it',t0 be' trimmed to shape by the cutter, there may be, :is seen iu Fig. 1iixed to the table d a right- 'angular piece, q, in which, asiii guideways, are

fitted a pair of slides, of, which have nuts projecting through the hack side of q, there being in one uut threads of a reverse though equal pitch to the threadsin the other nut, so that a right-anddeit threaded and equally-pitched screw-shaft, s, willf'by rotation in one or the other direction, separate or move toward each 'other jaws t, which are 'fixed to or form part of slides r. Said jaws 1. vare made to iit the' The upper inner edges of the jaws are made Y to iit in thecreasebetweenthe rear part of the sole and the counter of theshoe and protect the latter from the action ofthe cut-tei', and, if desired, may form a bed on which the cntter` edge may act in severing the superfluous leather I `from *he rear outline of the sole. The cutter beingelevated,l the outer ends of thepieces n will be spread apart from the shoe, and,-the

-jaws't'heing open, a sho'e may be introduced between them, and then clamped by them in position where the rough heel on such shoe will he trimmed on its curvilinear outline by descent of the cutter, the pieces o sliding down ou the pieces 11- and expanding the, cutter, Ry,

adjustment of the pieces n thc width of the heel may be varied. .Instead of allowing the 'pieces n to come into contact with the boot or sli-'oe counter, they majv come into contact with projections u, made on or lined io the jaws f.

ln Fig. 2 the cutting apparatus is the same as that shown in Fig. il, but the jack or holder diiers .in'construction from that shown in Fig. l. The base-plaie ol' this jack .lfSlS loosely on lne table (l, and has pivotedto ears w a piece, zr, which is adjustable at its rear, as ln the center .line ol' the piece aj. at right angles io the line of the pivot-centers in the ears w, are two cars. y. to which a lastblock, ispiv otcd. a part ol'said' block extending below the pivots. and havingin said part a nut, by which and a www, n', working therein, the angle ol' the lnslrbiork can he changed with reference io lhe lop oi' tabled andthe base ol' the piece 1, the piece .r being slotted where screw u passes through it. The top of the last-block tive toA the cutter;

i is slotted to receive a tongue formed on the throat of the last. 1 ln the last-block is pivotcd, at 7)', a pin that enters a hole formed in the last, a part of 'the pin extending in an opening in said block below the pivot at b, there being in said 'part a nut in which a clampscrew, n', works through a slot inthe lastiolock, said screw affording means for adjustment of the last-pin to its angular relation to the groove in the top of the .last-block.

At the rear ot' piece :r is pivoted to ears d a swinging arm, e', to the top of which are pi voted alipcr-armsj", so arranged that they may he adjustedto any desired opening. All ol' these varied provisions l'or iuljustment of the last holding and supporting mechanism are iliade so that shoes orfboots mounted on variously-iitted lasts may be accurately presented to the action of the cutting-knife. The saine kind of jack may also be used to present a boot or shoe mounted on a last to the action of other mechanisms designed to operate on' the soles or heels of boots or shoes. VWith this jack the clamping and holding jaws i, (seen in Fig. 1,) which enter `between the sole andthe counter, are dispensed with, and the calipering-arms In operate directly on the counter, or on the sole-edge at the shank part; ln Fig. 2 is shown a rocker, g', to one arm, h,of which is attached a stop, j', which is preferalolj,Y forked, the purpose of said stop being' ce serve as an abutmentwith which the heel comes in-. to contact, so as to determine its position, rela The other arm, i", which is fixed to the roeker'g, is slotted, and a pin, k', liXed in the crosshead, operates to nieve the stop j back out of the path oi the cutter as the cutter and cross-head move down, the

`stop lbeing restored to its position when the cross-head rises. When lasts'are to he supported by their necks, we propose and practice making a series of anjr number of lasts, within reasonable limits of variation in size, ol' uniform height from the crownof the ball and heel to the supportiiig-surface of the neck, and then ina-ke the distance i'rom the rear 'of each last of -ihe series 'ro the last pinhole er other indicator of longitudinal position with .reference to the last-holder the same in all the lasts, so as to avoid need for adjustments of the last-holder.

or projections majY be made on the lasts anda groove or depressions in the last-holder, or vice versa, or the necks maybe made of equal size to lit in a socket formed ,in the last-holder, or vice versa; but where lasts are made at random, with holes for last-pins hored without To keep such lasts from lat -cral swaying on the. last-holder, equal tongues
