Applicationiled September 2,2, l1922. Serial-No. 589,902.

To @ZZ whom t may concern: Y y Be it known .that I, LAWRENCE E; JOHN- SON, a citizen of the United States Vof nierica and a resident of- Melrose, in the 5 county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in Rough Founders and Channeling Machines, of which the following is a specification. l

This invention relates to rough rounders and channeling machines to be usedin the manufacture of boots and shoes and is an improvement on the machineshown and described in U. S. Patent No. 1,149,369, issued to ine August l0, 1915.` y

The niainobj ect of the present invention is to provide mechanism whereby the knife supporting block may be held in firm contact withI the Vwork during ,eertain operaduring other operations.

T he invention consists in cam actuated mechanism which will automatically vary ment of parts which will bel understoodV readily by reference tothe description of the Se drawings and to the claims to be hereinafter gi ven.

For the. purpose of illustrating the inven-A tion, one preferred form thereof is shown in the drawings, this formv having beeny foundl to give satisfactory and reliable results, although itis to be understood tliatthevarinus instrumentalities of whichv the.- invention consists can be variously arranged and organized, and that vthe-invei'ition is notlimited to the precise arrangement and OrganizfzatioiiY of the instrumentalities asfj herein shown and. described, except as required by the scope ofthe appended claims.A @f lthe drawings: s-

Similar characters already shaped, saidfview being Vdrawn to indicate like e parts throughout the severalrfigures of the draw? ings.

' In thedrawings, 10 is the base of'ia-.frame 11, having bearings 12, in which is revolubly mounted ashaft 13 adapted. to be driven by a pulley 14 loosely-mountedthereon.

- The shaft 13 has secured thereto the lCam disk l-and the eccentrics 16 and 17. This shaft 13 has also secured thereto a HyV wheel 18.

The pulley 14 isv providedwith a hub 19, :1;5

having' alflange 20 thereon, with which: Coacts the pins 21 secured in the forked end of a lever-22 `mounted upon Va fulcrum pin 23,1Said lever 22 ha-vinganarni 24 extending; therefrom, the outerend `of which is connected' by means Offarod25 to a suitable treadlemechanism, which maybe ofgainyY wellY known Vconstruction and. consequently is n'otshown in the drawings.

.WN/Then ,the treadle mechanism is operated to depress the armVY 24,*the lever V22 will ,Cause the pulley 14 to be move-df into a 4frictional engagementjwith.- the flyfvvheel 18,'inthis Y* Y manner effectingthe rotation of -thef'shaft135.` Y.

'outwardlyffon theshaft 13'- and ldisengage outer end of a bracket 26 secured to a column 27, to. the upper end of which the base 10 is secured. i

The tram`e11 has extending VtherefromV a pin 28 on which is mounted the lever 29, the lower end of which is provided with a roll 30,v bearing aga-inst the cam 15. This lever 30 is provided with a downward extension 31 between which Yand the pin 32 on the base 10 is a spring 33 which retains the roll e 30 in contact with the periphery of the cam 15 at all times.

The upper end of the lever 29 is with a bearing 34 in which is mounted a shank 35, theupper end otl which isV forked as shown at 36 in Figure 1 of the drawings. Between the forked end 36 and the upper end of the bearing 34 is a spring 37,V which forces the forked end Y36 upwardly. Piv oted to the lever 29 at 38 is a lever 39 having'tormed therein a slot 40, intowhich extends a'pin 41 Vsecured tov and extending outwardlyfrom the shank 35. VBy means ot this lever 39the shank 35 and the 'forked upperpend 36 ,thereof may he moved downwardly in the ybearing 34 against the tension ofi/the spring 337. This movement is per- `termed when it is desired to insert new work to beoperated upon,` and as soon as the new work is vproperly positioned. the pressure upon` the lever 39 is released and the spring` 37 moves the work upwardly against the member 42.

yThis member 42 is slidably mounted upon the plate 43. secured to or'iormed integral Y withthe upper lend of the frame 11, 4said Vvteedingp 4member '54,' tnesai'd Vpres-:ser

Awise' ojfathe plate 43, and

plate 43 extending into a groove in the under face ofthe member 42 and forming a guide therefor.V` This slid'able member is provided on one side with fa slot 44. in which is positioned' a lever 45 pivoted to the trame 11 means Aota lixe'd pivot"46,'and having at its upper end an operating handle 47.

lThe wallsoic the slot 44 are curved and bear against theedges of theV lever 45 so that when'. the operator ac-tuates the handle the member. 42 maybe adjusted length- A i secured in an adjusted 'position by means of the clampboltY 50'"extendingr through a slot 51 in the slidable member 42. 5 e front end vofthe slida-ble vmember 42 has an opening @extendingtherethrough'. in which is positionedV the operating-end of the presser feot' or l work-ieeding member 54. i The reanendof the presserfoot 54V extendsithrough a, transverse slotin theuppei end `4 oli a rodv'i'and is clamped in position therein by means- (ifa nut'561 "{By releasin this-*nut 56 `tropacontact with the work!

provided The lower` end of the rod is secured vin a housing S'Qhaving a eylindericalopen ing' therethrough, fitted to the eccentric 17.

TWhen the shaft 13 is rotated, the rotation of the eccentric 17 will cause the rod 55 to be raised and lowered, and also tilted about the axis of the ulcrum pin 58. As a consequence oi' this movement, the operatingvv end oi? the work-feeding'. member, or presser foot, 54. will bebroughtinto con-` a-ct with the work and impinge ther-ecru and then move the work a slight distance bel-ore Ysaid operating end oi" said presser ili'ooty is again'raised-from contact with said workfto return toits normal' position;

vThe frontA end of the plate 43 has secured thereto a welt gage 60 by means' of a screw 6l. Beneath the gage 6() is 'the chisel 62. The chisel 62 is secured by means ot a screw 63, or some other device,'to a vertical rod 64 mounted in a bearing 65 in the frame 11. and 'having its Vlower end clamped to`a split member 66 b v means ot the screw 67.

This member V66 extends through a bearing 63 in a member 6th the` lower end of which is provided with a'cylindrical opening" therethrough to receive the eccentric 16-` V"As the shatt'13 rotates',

the revolution of -V the eccentric 16 vwill Acause the chisel sup- 'porting member 64 tov be reciprocated' in itsbearmg65. lWhen'in the extreme of its uppermovement7 the edge of the chisel 62 ,is embedded slight ly in'the lower face ot the welt gageY 60,;which is made of bronze or some similar sott material so as not to iniure thecuttmg edge of said chisel.

The front end ofthe welt .gage 60 extends beyond'rthe sides of the plate 43 and is vindicated at 7() to permit *Y roviding; means whereby said block-V tilted tov accommodate itself to lThev tiltingot the block eominginto contact with the upper"Y i face ot-fthen'forked.` vport-ion 36. *whilezthe movement in fthe opposite `direction isf limited by'. 4means otr. downwardly extending pin13 eomingi, 1nt o contact with the rear 'tacefroiisaidforked portion=36.

tending from the rear of the block 71 beyond the front face thereof, and having :1. clamping nut 76 threaded to the projecting en d thereof. By turning the nut 76 the channeling knife 74 may be clamped in' any desiredv position. By loosening the nut, the channeling knift may be adjusted to give `varying degrees of'cut during the formation of the channel. Y i y The upper end 'of the block 71 is cut away below the operating end of the channeling knife 74 so that when it is' desired to use the machine for rough rounding without forming a channel,- the channeling knife may be moved down below the upper face of the block so that no cutting operation will he performed. This cut awayportion beneath the operating part of the channeling knife .also provides auneans for taking care of the chipsk formed during the cutting of the channel. l

The shank 36 has a-longitudinal slot 77 cut in its lower end, through which extends the lever 39. This construction provides a means for preventing the rotation of the shank 80 within its bearing 34. I

In the frame 11is mounted a shaft78 having an operating handle 79 secured toone end thereof. The opposite end of this shaft 78 has a projecting lug"80 radiating therefrom. This lug 80 extendsY into an Vannular groove 81 inthe rear end of the pin 28, on which the lever 29 is mounted.

By actuating the handle ,'79 this pin 28 and all of the parts supported thereon may be moved lengthwise of the axis. of said pin 28 into any desired position. vThisconstruction provides a ,means whereby the` position of the operating endv of the channeling knife may be adjusted longitudinally relatively to theY welt gage and the chisel 62. v Y

The eccentrics 16 and 17 are so timed that in the operation of the machine the presseri foot 54 and chisel 62 are both at their highest point at the Ysaine time, and the cain'lfVV permit the cutting` to take-place at 'the i is so constructed as to operaion of the Vknife 74 same time that the chisel`62 and the presser foot 54 are in their highest positions. VAs

a consequence ,ofjthis condition, the-*chiselV 62 will be in the work when the'knife v74" is cutting the .workv to'- forni ra channelthere in. kTherefore, the chisel 621 will holdthe substantially the work from lateral movement, during the channel cutting operation.

The eccentric 16 has a greater 'throw i thickness of the ivork, and as a consequence the presser foot the Work preparatory to feeding just before the chisel has left the work, and this Work will then be fed a predetermined distance before the chisel on its return stroke again enters the work. v

The presser foot 54. having coi'npleted this feeding operation, vwill again be lifted from the Work. The chisel 62 will be .forceil through a new part of the iror and the channeling knife 74 will cut a new part of the channel inthe sole.

t will be seenfthat by the construction herein shown and described, the stroke of the knife 74 is divided on opposite sides ot'- center line perpendicular to the tace 'of the sole being cut, thereby `producing a clean-cutichannel. This obviously is a great advantage. y
