To all whom itnuty concern Be itknowu that I, WILLIAM Ducnnmraof Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented a new and. useful Iraprovement in the Manufacture of Boots and Shoes,

namely, a Machine for Molding, Rounding, and Ghanneling tbeSoles thereof, previous to their being applied to the uppers; and 1- do hereby declare. that the following is a full, clear,' and' vexact description of the same, due reference being had to the drawing accomvpanying andforming part of this specification.

Figure 1 is a front elevation. Figure 2fis a side elevation.

Figure 3 is a plan'of thebed-plate or table of the machine.

Figure 4 is a vertical central. longitudinal section of the same. Y Y.

Figure 5 isaI perspectiv view ofthe segmental rotating block and leverar1,'with the cutting head-v block and carriage attached thereto.'

Figures o, 7, s, aan@ 1o winte referred wenn explained as the description of the invention may require.

. Figure 11 is atrausrerse sectioirof the formingiast.

Figure 12 is a; longitudinal section of' self-adjusting joint.

The object of my -invention is to perform with ouemachine, and at the same time, worl'r, which, by the present mode, requires three, and sometimes four,

machines, namely, molding, rounding, andv channeling,

technically sorcalled, the soles of boots and 'shoes previous to their being secured to the uppers.

The first operation 'consists irl-molding thesoles in such Yn. manner that the uudersurtaee will conform vto the shape ofthe b'ottomof thelast used; the second inouttiug round the edge ofthe sole to the requiredl shape; `the third in cutting a gioov'c or channel to receive the stitches, it' 'sewed; if pegged lor nailed, the channel' can be altered to suit.the work.

The frame of the machine'is made in four' parts; as shown in dig. 2, one front, one hack,4 and two side pieces, marked an, a, securcd'together in the u sual manner. l c

-On each side of the framo'is a pulley, aorer which passes a chan, having one end fastened to the lower cross-bar of the mulder-frame b 1:, and the other tothe weight or counterpoise b. This couuterpoise is made of suicient weight to drawup and keep thc frame b b in the position shown in tig. 1.

, At the back or inner end of theit'op side the curved bar or goose-neck issccurcd, marked @having on its outer end-the'box-bearing a?, through which-the upright or moitier-shaft b passes.

On the top ofthe Aframe n, a` res-ts -the bed=platexorA table d dfhavin'g a centml-longtudnal recess in its upper surface forthe. reception ofthe slidingbar or carriage (11,.towhlch is attached the forming-last or,

bed b?. This forming-last isshaped on ,its upper s urface or face like the ordinary last used in thefmanufacture of shoes, but here' the resemblance; ends, itsoutf, lines being the form of the outer sole of a shoe, and

at right .ngles with the'level of -tiie' upper snrface,.

thus' forming a continuous vertical planeur bearing,

against which the rounding-,knife t, (see lig. 5,) presses tudinally in 'such proportion, that the hase of thefornai ng-lastniay pass through, and provided on its' upper surface with a circular groove, ll, in which, fitted-w that it may traverse freely, is the segmental blockl VTo the face of this bloc-k, at right angles'with *its` `inner or straight edges, is axed the'arm o r lever j;-

Thisspringis placed on the'side' ofi-he lever-armf, (se'e fig. 3,) andis so adjns'teibthat it will, by its act-ion on 'the'iodslq q; set the pulleys d di alternately i'n ;gear.

innerjhfangerii2l and postq, are two tripper-bloeks, p

and p1, (see 'iig. 4,) extending upward until they pass the center oi' the screw d, there being a 4circular cavity in. the upper end of cach to preventv the screw from coming in contact therewith.

rneach side 'of the bedlplate d'd, iig. 3,' are the asl-'- justing slots@ e, through which, into the side pieces ofthe frame, pass the screws e.- By means ot' .these adjusting 'slots and screws the operator is enabled to In thecenter of the upper end of this nut there is' a 'cor1 esponding*fmalc scle'w', into which the fasten-.-

ingb0lt,'seen at 'the inneror toe end of the formingl last b3, passes, thus securing the forming-last or hed toits carriage d1. l 4 To find the positionof the outer hollow screw, the carriage dlmust bcbrouglt in line with the outer end .oi' the bed-plate d d, when the center ot' `the circular groove d is its position'.

To iind nthe position anddimeusions of the slot in the inner end ofthe carriage, it will be necessary to ilnd the cxtreme difference in the length of the work i that is to say, if the shortest forming-'laster bed be -six inches long'and the longest,be ten, the slot will haveto be four inches long, to which must he added the space taken up by the traversing-nut if. If-the nut .betwo inches wide, theV slot must be-six inches long, and its inner end be-iive inches from the center of thehollow screw in' the outer end of the carriage d. To nd the positions of the tripper-blocks p and p* s on the shippingbard, (sec iig. 4,) place the outer end of thecariiage din line with the front of the hedplate d d, and place the'pulleys d ont of gear; then` thetripper-block p must 4he so placed that its outer face will touch the iunerfacc of the'clntch p, and the i distance between the inner face of the tripper pl andthe outer face of the traversing-nut d* will be the same as the distance between the centers of the fast'- ening-bolts in the forming-last b3,

Below the working joint` is an,- other projectingstud, '11?, haring a ,slotinthc end to receive the shatt of the shipper-N. This stud, while it allows thc shipper to m'ov'c back and forth freely,

acts as a bra -e against any side motion or strainin shipping or otherwise.- Projecting out from theleft hand bearing n* is a har,`u, bent in such a formv that its outer end runs parallel with its fiwe;'this braces the shipper. while performing its work.' On the lower end of the shipper b is a widey plate, on thc'inncr face These cams arose `fitted onY of 'whiohis an inclined plane,`mad in su'ch propor` tion that it will act in unison with tl1e`inclined plane n4 on theontcr face of the canili. .The crooked bar At the end of the scroll on the face'of the cam l is achip, n", its frontendbeing wpdge-shaped, shown at l, iig. 10. This chipor block, actingagainst the projecting lip n on the. end ofthe bar 17, throws the cam L5 out of gearand the cam 1 in gear, thus relieving the pressure, when, by the action of the counterpoise bl, the'molderg'arne is drawnup 'andassunres the pcf sition shown'in iig." 1.- f i f?, iig. 5, is a perspectivevicw of the cutting-head carriage. -adixed in working order to the arm Y f, as heretofore described. To the outer end is affixed a' zigzag springmarked :c z, l ravng its lterminus at the -hnndlea This' springvprees with sufficient -force -to keep the carriagej? in its proper position. To the inner end ot' .this carriageattached by a pivoijont' which allows it-to rotate freely to rightad lett, isfthe carrier 'f, in'which the cutting-head f5, governerhlpy the spiral springs yly, moveshack and forth. 0n the inner end of the carrier, raiscda trifle above the sure;

'The faces of the' lingers area-little ovaling in form, the greatest fprornnencc 'on eachb'eing at equal dis-- tnnces from the edge of -thcronn'ding-knife t,as shown in fig'. 7, marked 'by' two dots, From the d ot to'itsin'ucr side the leading ugerjm? is made alittle angling. This is done to ease the knife when turning' round thetoe end of the sole, the angle of whichis sometimes veryncute. Y c

The follower 'm5 is the width of the ronnding-knife narrower than the leading ingerm.' This is done toallow the knife to be drawn bacloand thnsgivc the molder'roorn Jto perforrn its work.

At the inner Aend of the cutting-head. f" is a slot or recess, and in the ext-reine e'ud of the goose-neck g, fastened to its upper-surface, is acci-responding slot. .'1 hese' are for the reception of the rounding-knife..

In the outer' end of this plummet-block is the hollow bearing of the rocking-shaft g. Near its Aouter 'end the rocking-shalt i]s bent in the form of adonble cnrve,-its extreme outer uppcrend running parallel with tho-body'ot' the shaft.

On this outer endV isaiiixcd the'carrier g", in which 4the channel-cutter gis placed, there being for this purpose a dovetailed groove let into the carrier, in' which the channel-cutter is fitted in snch a mannertha't it will traverse freely.

At the upper'end, on the face, andhaving its ful-y crum on the outer side of the carrier g', is the arm or 4 leverl g-, to' wl1ich, bymenns 'of a connecting-link, is -ttached the,channel-cntter.
