To @ZZ whom it may concer-n.-

Be it known; that .we,WARRn`N C. vEvA-Ns,

of Exeter, countyl'of Rockingham, State 'of New Hampshire, and HENRY D. ALLARD, of

5 Bradford, and JOHN B. ,KENISOBL of Lynn,

county of Essex, StateofMassachusetts, have in vented an Improvementin Sole-Edge-Blackf ing Machines, of whichthe following description, in connectiouwiththe accompanying :o drawings, is a specification, like letters andl numerals on the drawingsrepresenting like parts.

This invention 'hasfor its objectA the production of a novel, convenient, and highly- I5 efficient apparatusf'or applying blacking or other coloring-matter tothe edges of boot and shoe soles and heels rapidly and accurately with an even coating of any desired density.

Means are provided to absolutely prevent 2o the coloring-matter, which term as herein used includesv blacking, from touchingithe. upper or the top of the sole when desired, as" in fair-stitch Work, the coloring-matter being applied without spattering by a rotary z5 transferrer, against which the Work is held,` and the arrangement Vof the mechanism is' such that the coloring-matter can ybe appliedto the sole edge only or to the edge and top,

as may be desired. 30

tor moves the work the color isapplied to that portion thereof .Whichhas been j ust beg5 fore smoothed, so that subsequent rubbing down is obvia-ted.

In the course of our experiments to improve apparatus of this class so that the coloring-matter shall be applied in a smooth;

We have also made provision for scouring, "ond bearing a. or smoothing the sole edge jnstbefore the color is applied thereto, so that as the operafast on the shaft.

plyingcoloring-matter to boots and shoes as willbe described. 'Fig. 2 is ayerticalsectionalview thereofon the linearer, Fig..l, looking to the'.right. Fig. 3 is a rearfelevationof .the'apparatus Figa is a like, view, 'enlargedtaken through the main or driving `shaft andv a portion of-o'ue of kthe reservoirs forthe coloring-matter, showing also in section the guard orshieldand theintermediate controlling devices between the reservoir and the color-transferrer. Figi 5 is an inner. side view of the clutch mechanism on the drivingshaft shown at the right,: Fig. Y1'. Fig. 6 is a vertical sectional View taken through the longitudinal axis of the main or driving shaft, showing a portion of the clutch mechanism. Fig. 7 is a partial Y'vertical sectional view of the vmechanism shown in Fig. 4, on the line as' looking to the left,'with the color-transferrer omitted. Fig. Sis a detail elevation showing the device for scouring or smoothing the edge of the sole and in connection ywith the colorapplying mechanism. j

Referring to Fig. l, the mainframe A, of suitable shape to support the working parts of the apparatus, is preferably mounted on a shelf or-stand A', said frame having an upright A2, which provides a bearingja for the e main driving-shaft B, the latterhaving a sec- A gear `C is fasten the shaft B adjacent the inner end 4'of the bearing a', and at the other end of the said bearing'abuts lthesleeve-like hub b of a clutch member B',

bly mounted on the hub b and retained in 4place by a collarbx, fast on the main shaft, said clutch member having its inner face concaved .or dished, as clearly shown in Fig. 6. A dog b2 (see dotted lines', Fig. 5) is secured to the outer end of a stud b', mounted to rock in the clutch member B', saidY ldog at times engaging a stop b3, secured on the inner or A concave face of theclntch member Bavhile on the inner side of the member B' a trigger b4 is rigidly secured to the stud h'. A spring The other or loose clutchl member is shown asa cone-pulley B2, rotata- IOC Aroek-shaft b5, Figs. l, 2, 3, and 5, is mounted on the main frame and in the standard A2, f

a set-screw 5 adj ustably securing on the rockshaft an arm 1), on which is mounted a headed spring-controlled stud 137, normally held in the path of movement of the lip of the trigger by a suitable spring S, (partially shown in Fig. 5,) the tripping of the trigger disengaging the dog and stop b3, and so disconnecting the clutch members when the lip of the trigger engages the headed stud 117, the rotation of the clutch being in the direction of the arrow 75, Fig. 5. As shown in said Fig. 5, the trigger 114 is supposed to have just engaged the stud 1)?, and slight further rotation of the'clutch will tip the trigger to move the dog 122 out of engagement with the stop 133. By making the trigger double, as shown, its inner end engages the hub of the clutch member B when tipped inward to thereby prevent undue movement of the trigger.

An actuating-arm bs, (see Figs.y l and 2,) fast on the rock-shaft 1), is adapted to be moved by the operator to rock the shaft b5 in the direction of the arrow'O, Fig. 5, against the spring S, to thereby Withdraw the clutchcontroller stud D7 from engagement with the trigger, so that the clutch will be thrown into operation and the main shaft rotated. The arm 1) has laterally projecting from its inner face a lug 1), adapted to be engaged by a shoulder 1910 on a lever blz, pivoted on the frame at 1113, so that when the actuating-arm D8 is depressed to support the apparatus the shoulder 1110 will engage the lug 1), and thereby maintain the clutch in operative position until the operator, by lifting the lever 1212, releases the lug, permitting thereby the rockshaft b5 to return to normal position and through the clutch-con trolling stud 1F engage the trigger and, as described, effect the disengagement of the two clutch members.

The main shaft has secured thereon (see Figs. l, 3, and 4) separated collars 7 S, to receive between them an arm c, mounted to rock on the preferably-enlarged portion B3 of the main shaft, said arm at its rear end having a bearing c', through which is extended a shaft c2, on the outer end of which is secured a suitable scouring or smoothing roll cx, having a roughened periphery and, as shown best in Fig. 3, slightly conical in shape. At its inner end the shaft c2 has fast thereon a suitable pulley c",to which rotation may be transmitted by a belt-(not shown) from any suitable source of power to rotate the scouring-roll 0X in the direction of the arrow G5, Fig. 8. A bracket cl on the standard A2 is threaded to receive an exteriorly-threaded sleeve c5, provided with a suitable check-nut c6, the upper end of the sleeve being located` below the rear end of the arm c, as clearly shown in Fig. S. A spring S is'attached at one end to saidvarm and at its other end to a rod c7, extended loosely through the lower end of the sleeve c5 and threaded to receive thereon an ad justin g-nut cs, by which the tension of the spring may be regulated. lt will be seen that the scouringroll is thus supported to rock bodily by and at the rear of the main shaft, the spring holding it in a yielding manner against the sleeve,

the latter being adjusted in its bracket to suit different shapes of shoes and to cooperate properly with the color-transferrer, to be hereinafter described.

The spring S can be adjusted independent of the sleeve,and the adjustment of the sleeve will also,if desired,a'ffect tension of the spring.

The color-transferrer is herein shown as an annulus T, having a continuous non-metallic and slightly-yielding peri phery,and up to the present time we have obtained the best results with a rubber transferrer or one having a rubber periphery, as the color will thereby be ap-V plied to the Work smoothly and evenly without streaking or spattering.-

)Ve prefer to give a slightly-conical form in yan outward direction to the periphery of the transferrer,to thereby secure the more perfect f distribution of the color over the work, the edge of the sole being held by the operator against the transferrer as it is rotated, the latter being applied, as shown in Fig. Ll, to the yenlarged portion B3 of themain shaft and abutting against the collarrS.

The edge of the sole from the shank portion forwardly around the toe is preferably scoured, while it is unnecessary to scour the shank portion, and we have shown our apparatusfas provided with two transferrers TT', the former only operatingin conjunction with a scouring-roll, so that the shoe will be first applied to the transferrer T, the color being applied as the operator draws the shoe toward him, the rotation of the scouring-roll being such that any dust from the l.sole is thrown away from the. transferrer, and afterward the sides and fore part of the sole edge IOO IOS

are colored, and the shoe is then applied to the transferrer T,which colors the shank. This arrangement, however, is largely a matter of convenience to the operator, as one machine can thus do the work of two separate ones, while it will also be obvious that the scouring-roll can be thrown out of operation at times, if it is desired to use one and the same color-transferrer for both the shank and fore part of the sole. The transferrer T is mounted on a shaft B4, held in suitable bearings on the frame and having fast thereon a gear B5, which meshes with an intermediate gear B in mesh with gear C, fast on the main shaft, so that the two transferrers are rotated in the same direction. Each transferrer has its own reservoir for the coloring material, which term includes blacking, and as the reservoirs and their operative parts are counterparts one of the other only one will be described in detail, the reference-letters D 61d of the one corresponding,respectively,to the letters F. e e' of the other.

' The main frame A has on its front and rear IIO IZO

work of the apparatus.

'scenes fe sides lugs A16 A17. to receive the shanks of yokes al a to embrace the upper ends of the reservoirs D E, respectively.

Thelreservoir D (see Fig. 4:) is open at its lower end andreceives therein an upturned annular flange d, formed on thebottom plate D', which bottom plate is provid ed with a lateral. extension D2, provided with a boss d','

through which is extended a screw-bolt d2, the latter fitting into a horizontal notch dx. in a part of the standard Awhile a thumb-nut d3 at the opposite end of the screw-bolt acts to clamp the extension D2 firmly to the frame- The reservoir is secured to its bottom plate in any suitable manner, either by Soldering or by a ground joint to hold in the color without leakage. The bottom is slotted 'at d4 above the transferrer T, said slot serving as an outlet furthe contents of the reservoir, while a valve, shown as a rod d5, is adapted to move longitudinally in the reservoir-bottom, the inner end of the rod passing through an ear d on the under side of the `extension D2, longitudinal movement of the valve opening more or less the outlet, a springs', connected at one end to the ear d and at its other end to a pin d'7 on the rod, normally retracting the latter to open the outlet dl. The piu dis adapted to be engaged when desired by a gravity-latch cls, pivoted on the exterior of the extension at Z9 (see Fig. I) to hold the valve in such position as to close the outlet, as would be the case when the machine is not in use.

The coloring-matter does netpass directly from the outlet d4 onto the transferrer, but onto a small distributing roll f, pivot-ally mounted in rocking supports f', fulcrumed at j2 in the downturned iange of a block fx, attached to the under side of the bottom plate D', the outer ends of the supports f' being n icked to receive the annular heads of suitable adjusting-screws f3, :threaded into the block fx, so that rotation of the said screws will raise or lower the distributing-roll f to press more or less tightly upon the transferrer.

It is found in'practicethat the interposition of the distributer between the reservoir-outlet and the transferrer greatly assists in the smooth and even distribution of the ink upon' the transferrer, and also prevents spattering.

A piston-rod or plunger d10, vertically movable through the upper closed end DX. of the reservoir, has a head or piston (112 secured thereto to enter loosely the reservoir and at its inner stroke tol fit' quite snugly within the.

flange d, while when the'plunger is lifted its head C112 will be raised above the l(lange, so that a portion of the material in the reservoir can pass beneath the head vto be positively expelled th rough the outlet d4 when the plunger is next depressed.

A slide-rod mx, vertioallymovable in bearl ings 22 33 of the 'main frame, has l.attached thereto arms m m', which engage the two Vplungers d10 and elo, between collars 3 4 thereon, respectively, to effect the reci procation of the plungers, the slide-rod being depressed by a spring S5 and elevated by engagement with one arm m2 of a bell-crank lever pivoted on the main frame at m3, the other arm m4 of said lever being located in the path of and to be engaged by a cam-lng BS on the inner side of the gear B5, as clearly shown in Fig. l, whereby the plungers will be elevated and depressed ouce for every complete revolution of the transferrers.

We have provided means for automatically closingV the reservoir-outlets when the machine is stopped, so that the coloring-matter will not at such time flow, and for this purpose an inclined shaft 7L is mounted to rock in bearings in brackets 30 and 31 on the main frame and standard A2, respectively, said shaft being provided at its lowery end with a toe h'. in the path of and to be engaged bya tappet h2, fast on the horizontal controllingshaft h5, thev tappet engaging, as best shown in Fig. 2, an adjusting-screw h3 in the toe. At its upper end the rock-shafthas adjustably seeuredthereto an arm hextended forwardly to bear against the valve-rod e5, as shown in 3.when the parts are in the positions shown in Figs. l, 2, and 3.

the inner end of the. toe 71,' and the collar hx, fast on the shaft, said sleeve being provided with a forward ly-extended arm h2 adapted to bear against the exposed end oi" the valverod` d5 when the machine is not in use. The sleeve h5 has a toe h7at its lower end, provided with an adjustable stud 718, to be engaged by" a tappet h, fast on the controller-shaft b5. Now when the machine is at rest the two tappets on the'controller roel-shaftfb5 will act on the cooperating toes of the rock-shaft it and sleeve hi to turnV the arms h4 and h6 to the left, Figfl, forcing the valve-reds to nearly close `the reservoir-exits, so that the iiow ofvcoloring-matter will be greatly diminishedjt being sufficient to partially shut off the flow when the operator removesone booter shoe and is about to present another one to the colortransferrer. lf, as has been, described, .the coloring-matter is entirely shut off, as when the machine is leftfor the day or for any length of time, the operator will grasp the extensions M0716 of the arms 71,4 h6, respectively, pushing them to the left until each valve-rod is caught by its gravity-detentds or e8.

Movement of the valve-rods to the right, Fig. 1,'is limited by threaded studs d50 e5", mounted .in -the main frame and adapted to impinge against the varms h4 h6, respectively.

0f course a greater quantity of the coloring-matter must be delivered when it is thick A sleeve h5 is loosely mounted on the shaft it, between IOO IIO

than when it is thin, and in the former case hereinbefore described, a shield is unnecessary; but .it is necessary to provide a guard to protect the upper, and We provide such guard and at the same time effect the application of the coloring-matter to the top of the sole.

The bottom of each reservoir is provided with a standard, one' being shown in section at d20, Fig. 4, interiorly threaded at its lower 'end to receive a stop-screw dim, through which is extended a vertically-movable,shank cl2?, the upper end of which is received in a longitudinal hole C223 of the standard, the upper end of the hole being threaded to receive an adjusting-screw d24. The inner end of said screw is shown as bearing on a ange di, which rests upon the top of a spring s3, the lowerend of which is seated in the recessed upper end of the shank C122, and by adjusting the screw 24 the tension of the spring isvaried. A thin guard-plate 0526 is secured to the lower end of the foot CX22, adjacent the outer end-of the transferrer T, said guard-plater 7iiowing from the guide onto the top of the sole,while the edge of the latter has color applied thereto bythe transferrer T.l

The coloring-matter is prevented from passing under the lower edge of the guard-plate and onto the shoe by the groove d2?, inwhich the coloring-matter collects and drops onto the wire guide CPS, which thus serves not only to apply the coloring-matter to the top of the sole when desired, but it also furnishes a guide for the operator in manipulating the shoe, such manipulation being assisted by a bottom gage, shown as a truck n on a stud n', extended out from the standard A2.

The shank d is provided with a pin 45, Fig. 4, which rests on the top of the stopscrew C321, and by adjusting the latter the eX- treme lower position of the guard-plate and guide is provided for.

To prevent any accidental loosening of the stop-screw, a clamping-screw 46 is extended through the body of the standard d20 to bear against the stop-screw d21 and prevent its rotation.

The guard-plate is held in parallelism with the outer end of the transferrer T by means of depending ears cl2, bearing on the outer face of the guard-plate CX26.

The guard is used for all plain work and about the Shanks of boot and shoe soles; but with fair-stitch work it is necessary to protect not only the upper, but also the stitching at the top of the sole, and in doing such work the transferrer is moved slightly away from and out of contact with the guard-plate, so that vno coloring-matter will pass thereto from the said transferrer, and in Figs. 1 and 2 the color-transferrer T1 is shown as moved slightly to the right for this purpose.

The movement of the transferrer is readily effected by adjustment of the collar 90 on the shaft B4. The operator holds the boot or shoe in his hands, with the bottom of the sole against the bottom gage a and with the edge of the guide C128 in the crease between the sole and the upper, and the edge of the sole is pressed up against the edge of the rotating transferrer, this upward movement of the shoe and guide being permitted by the yielding support for the guide, and the transferrer applies the blackin g or coloring-matter evenly and rapidly to the sole edge as it is turned to present new portions thereto, the guard-plate protecting the upper efectually. rlhe movement of the boot or shoe is toward the operator, so that when the scouring-roll is used the sole edge is scoured just before it is moved into contact with the color-tra-nsi'errer. The operation will be precisely the same in fairstitch work, with the exception that, as has been described, the guard and color-transferrer would be slightly separated to prevent the passage of color from one to the other.

With some kinds of coloring-matter or stain it is desirable to maintain it heated when the apparatus is in use, and for that purpose we have provided burners P and P', (best shown in Fig. 3,) located beneath the reservoirs D and E, respectively, on branch pipes p p',

` leading `f rom a common `pipepx, which may be connected with any suitable gas-supply,

In the claims we have herein used the term coloring apparatus generically,l said term including blacking or other coloring-matter lor stain which is to be applied to the edge or upper portion of a boot or shoe sole.

In this application we do not claim in a soleedge-blacking apparatus a rotatable brush against which the sole edge is held with an adjacent reservoir provided with a dischargeopening to deliver its contents directly upon the brush, means to positively force the contents of the reservoir through the opening, and an automatioally-controlled valve for such opening, as they form the subject-mattei' of a claim in another application, Serial No. 681,502, renewed May 23, 1898, by two of the inventors herein named, the color-applying device in the present invention consisting of a rotatable member having a continuous yielding periphery as opposed to a brush the periphery of which is formed of a multitude of independent bristles.
