Application filed April 24,

To all whom it may concern:

Be 1t known thatlgdonx H. RIGBY, a hoe at Ber erly, in the county ofIEsseX and iState of Massachusetts,have iniented. certain 'Im' provementsin Sole-Edge-Finishing .Ma chines, of which the following description, in connection with the accompanying draw ings, is a specificatiom-like reference characin the several figures.

ters on the drawings indicating like parts This invention relates to edge setting machines of that type in which an iron for sett ing the sole edge is vibrated backwardlv and forwardly along the length of the sole edge, and in whichan'indenting wheel mounted adjacentto the edge settingiron in positionto operate upon the upper surface of the welt or similar substauceor sole;

Heretot'ore it has heenproposed to mount the indenting wheel in. various ways so that- .it might move relatively to the edge setting iron, against the action of a spring, to adapt the wheel for indentillilf fwelts 'or sole margins of different widths None of these structures has enabled anyprovisionto be made for conveniently adjusting the wheel.

' toward and from the surface tobe'. operated upon so as to readily accommodate solesiot' hfi ETQnt thickness.

An important feature of the present 'invention consists in provision for relative vertical adjustment ot'ed e iron and indenting Another feature of the ,inventio 'i com,

prises. a bodily movable indenting wheel which can be manually swung aside from its normal position to facilitate the-ren'ioval 'oi'i one iron and t-he substitution of another iron for it. p

In the illustrated embodiment oi. the 'iuvention, the indenting wheel is so mounted that it will follow the eontour ot the upper backed by its last. irrespective of the con- 5 tour of the sole,'wliil'e being carried by a ier type of machine;

swinging support ivhiclrcan be readily manually adjusted to permit the machineto be used ,tor, operating upon soles otvarying thicknesses.

It has been. proposed to ,n'ioiuitganzedge setting iron forpermissive: movement about l ahorizontal axis in order'to. m st theitool the vertical caused, [for example, by careless dent-ing .wheel so that such movement ot the iron does not vary the distancerelation heto follow a sole edge or varying relation to;

edge trimming. v The present invention pro-f v1d es.an independent mount ng for the n tween the indenting wheeland thesole edge.

To facilitatethe employment of an; edge finishing machine for .(l1i f6lf8nt grades; or

kinds of work, it eustomaryt nount the sett ng tool or iron so 'thatiltranbe replaced invention is to enable the change to be made quickly. In the machine illustratedto ex emplifythe inventlon, the vtool orsiron s so mounted that althoughit is-held securely in operative posit on, it can bee ected trom its holder bya manual. operation, such ejection being", preferably preceded by a displacemen-t of the indenting wheel. r j @Other features 'of my. invention will beeome apparent asrhereinafter described. In the acermipanying:drawings, the inventionisillustrated-in. connection with a 1 machinenof the type described inUnited States LettersPa-tent No. LOTSfiSAigranterl Nov. 18, 1913; but" it is to ,be understood that I do not limit myself to the use of my .im-

provements inv connection with I that p articu- In the drawings Fig. 1 is a side elevation of a. portion of a maehine of the type illustrated in the pate-nt 7 above rete-rerdto, said machine being equ-ipped. with Lmv improved edge setting and indenting devices; t Fig. 2 is a side elevation of the devices which include my present improvements.

Figs, 3 and tareperspeetiveview I speetively illustrating thetool holder and the time to be assembled.

When my;imin'ovementsare embodied in amachine of the 'tvpe'indicatedjin Figi'l.

the workto be operated upon is clamped n a jack or work support 12 {Fig 1) carried tool separated from each other but in posi-,

by a vertical post-in a frame member 13 and so mounted that it may have universal movement in a horizontal plane. A block ll. supports the tread face of the shoe sole and a rest 15 supports the tread tace oi? the heel. A U-shaped clamp 16 engages the counter partof the shoe and a clamp 17 is carried by a plunger 18 which is operated by a handle 19 pivoted at 20. I

The mounting for the edge setting tool 21 (Figs. 2, 3 and comprises a tool holder 2:3 having a shank slidably positioned in a -member which is oscillated in anextension 24 (Fig. 1) from a sleeve 25 that is to tatablv mounted in a bearing frame 26 which is connected by pivots 27 to two pairs oi" 'twin leversQS, 29. One pair of levers 28 is pivoted directl upon a lever 30, while the other pair of levers 29 is connected to the lever 30 through a bell-c ank 31, the latter being connected with the frame of the machine by an anchor link 32. Bvthis construction, the tool holder can be nuwed laterally toward and tromthe work. For a further understanding of the motions imparted to the sleeve trameQG and the parts carried thereby, reference may be had .to the Patent 1,078.684. is stated above, however, I do not limit myself to machines of this particular type, but it to be no derstood that, whatever the tips ot machinc may be, the shank and the holder and all parts carried therebv a re vibrated as usual along the. length of the sole edge.

Referring now particularly to Figs. 2, 3 and at which illustrate the particular features of my i. vention, the bi'ackebshaped holder 22 is formed or provided at its upper end with an ear 33, said brzurl zet-shapedholder being slotted or recessed and the two memaers thereo'f' novided with vertical wavsfiil in which an L-shaped "block is fitted to slide. Risingi'rom the upper portion of the block is a threaded pin. 35. said pin pass ing through the car 33 and jprovidt-id with nuts 37 by means of which the block can be raised and lowered in the ways 34. Pivot ally connected at 38 to the angle portion of the block is an arm 39 by which the stitch indenting wheel 4-0 supported in a swinging manner. said wheel being connected to a carrier ll pivoted at 1-12 to the lower end of the arm 39. The carrier 41. is .pivotally connected at 43 to the lower endotlever s -l carried by a rockshatt lf) mounted in the'end of the lower member of the L-shaped block 35. Thelower arm. of the lever ltis by preterence parallel to, and ot the same length as. the arm 39 so that the carrier can be swung without changing the inclination oi. the wheel axis. The lever ltis integral with or secured to the rockshatt one end of which projects through a slot in one of the check pieces of the holder T he upper end of the lever it has a slot 46 which receives a pin 4:? projecting from the upper end of the lever 48 pivoted zit-49 to the holder 22. The end of the rockshaft which pro ects through the slot 65 has secured thereto an arm 50 provided with a-tbumb piece 51 the purpose of which will be hereinafter explained.

T he reason tor the slot and pin connection i i? is to ensure permanent connection-between the levers i l and 48 throughout all vertical adj ustmcnts otthe wheel carrying block 35.

l he lower end of the lever 48 has a for wardly projecting and preferably rounded tip .Bearing against the back otthe lower end of the lever 1-8 is a sliding pin or plunger 53 which is slotted for a pin 5i mounted in the holder and pro ecting it back against the action oil spring transinitted through the lever 48, the lever ll and the member atl. In this manner the wheel 40 is not only adjustably supported but is also yieldingly supported so that it may move in and out relatively to the margin of the shoe sole so as to automatically accmnmodate itself to the varying widths of the shoe welt or corresponding part. The outer limit oi. movement or swing of the wheel 10 is detern'iincd by the inner endo't the slotin the pin bearing againstthe limit ng pin lhat is. when the spring 55 acts upon the pin 53 so as to swing the lower end of lever 48 to the left from the position in'Fig. 2 as tar as the slotin the pin Bil-will permit, the intermediate connecting lever 44. will transmit that an'ioui'it' of movement and no more to the wheel 4-0.

Consequently, when there is no work in place, the wheel :40 cannot be swung sotar out as to be out of position to be swung back again when the work is placed. in position for edge finishing and indenting.

The lever 4-8 also scrvesas a means for ejecting the tool 21 tronrposition. Thetool 21 is secured to a block Behaving a heel. or cam portion 57. by suitable means such as screw 58. The tool 21 has angular recesses 59 which engage the fulcrum edges 60 ot' the holder 22 to permit rotation about a horizontal axis to lit the vertical. t'ace oi the sole edge at all times. Said holder provided. on the inner walls of its cheek pieces, with ledges 61, one of said. ledges being cutaway or recessed as 62. When the tool 21" and its block 56, as shown in'Fig. 4,.are' inserted to position in the'holder 22 (Fig. 3), the block 56 is passed between the cheek pieces of the'holderbelow the ledges 61 and the upper portion of the tool 21 is pushed in above the ledges 61 until the side-lug 63 of' the tool drops into the recess 62. The parts 7 are so proportioned that at this time the fulcrrun edges of the holder 22 lit the I angular recesses 59'of the tool.

The slot! 6-1 formed in one of the cheek pieces of the holder 22, which slot is formed when'the ledge 61 is cut away to form the recess 62, enables a tool to be inserted under the lug 63 to lift the latter up if the tool should be stuck and it is desired to removeit. Ordinarily, however, the tool is easily ejected in the following manner By pressing against the finger piece 51, the shaft 45 is rocked and the lever 44' is swung so as to transmit swinging motion to the arm 39, thereby swinging the indenting wheel 40 away and up from the position shown in Fig. 2, it being assumed. of course, that at this time there is no work in place. The first portion of this movement carries the wheel 40 some little distance away from the tool 21. During continued actuation of the rockshaft arm 50 by means of the thumb piece 51 the lever 48, owing to the slot and pin connection 46, 47 with the lever 44, is actuated so that the tip 52 at the lower end of the lever 48 contacts with the cam portion 57 of the tool block 56 and lifts therear end thereof up until the lug 63 clears the recess 62, and then a slight further movement throws the tool or iron awayfrom the supporting ledges to enable a new tool to bequickly substituted for the one removed.
