To all whom t may concern:

--Be it known that I, KONRAD VVINKENBACH,

'a citizen of the Republic ofGermany, residing at Newark, in the county. of Essex and State of New Jersey, have invented new and useful linpioven'ients'in Graining Toels, .of lwhich the following'is alspecification.

This invention: relates to improvements" Vin tools usedjby painters in producingvv on flat surfaces the appearanceof longitudinally cut Vvwood, or marble artificially simulating-the natural markings, striationsY or grain thereof with more or less fidelity.

The operation of graining is usually performed by applying a` flat color, `constitutj king the Ybackground .or base, with `abrusli and afterthis hasset or become hardened.

a darker color representing,thesveining proy duced by successive annular growths, thisv color being applied with ajcoinb-like vtool in anirregular fashion and further distributed by dabbing with a ragr or sponge toprorluce the desiredeffect, this' process being crude and accomplished satisfactorily only by an artistic and experienced workman.v

It is also known that graining tools inthe forni of a roller having `handles at its ends l have been used, the vroller being provided vwith a sleeve circumferentially engraved to Apresent` the markings ofa relativelyshort section of the desired graining, which is therefore necessarily duplicated A aty ,each full revolution of the roller, or the roller may be cut in vcameo itself. i

Obviously several such rollers, bearing different patterns may be used consecutively, but it is apparent that the loss of time in changing from one to another and thc waste of paint is objectionable.

Itis further to be 'notedltliat the handles of such rollers prevent their use-in interior corners and lwithout the handles the limple-y ment cannot conveniently be used.

It is therefore the principal 'object of the present invention toprovide a graining tool of the roller type having a flexible sleeve so various changes in its manipulation.

A further feature'is in the provision of :i roller having openings in its ends into which the lingers of an operatoi-may be inserted to manipulate the saine when conditions are such that the usual handles cannot-be used.

Another aim is to produce a graining tool of roller type, having a exible sleeve or ends so Aarranged as to be free to rotate upon their.spindles,l rigidly secured to the roller,

or -entirelyai'einoved at'V will.

vsheath and. provided with handles at its `Tl'iese" severalfeatures ,are vaccomplished ing afmaterial'part of this disclosure` and `Ain which Y Figure 1 is aperspectivev view showing aV `framed panel and illustrating one vmanner of operating a roller made lin accordance witlithe invention. i f

,the novel construction and, arrangement (fof ygrparts' hereina-ftei' vfully described and shown iii the-accompanying drawing, formy Figure 2 is aside velevational view showy .ing a coinpleteeinbodiment of the device.

Figure 3 is a central longitudinal sectional view of the same. "fr l y Figure 4 is a side viewofvthe roller in construction. a Y

Referring ni.ore"paiticulaily to Figure 1 of the drawing, a panel, designated bythe fnuinerallO, is shown as being surrounded vby a raised frame 11, the face-of the panel Y Y detail, partially broken away. to` show the n soy Y showingia' grained finish as at212 over a por.-

tion of itssurfac'e.

The roller, .shown in detail in Figure .4

consists of asolid' cylinder 14zof any `desired uniform diameter, and of anyjsuitable niay terial, Wood being preferred because of its lightness. andlready availability.

In eaclrendiof the roller 14 are axial recesses 215 sliapedtoreceive one of the fingers `of each of the hands of an operator Where- Vby the roller may be manipulatedover ay surface as'indicated in Figure 1, Where, because of the raised elements 11, handles Ycould not be used.

In ordinary practice however handles 17 are employed, the handles beingof such shape and sizeas to beconveniently grasped by the hand and provided Vwith acentral rbore-18 to freely rotate on spindles 19 havingv heads 20, and'screW-threads 21 on their opposite, inner ends tol engage directly in v`the ends of the roller at'tlie bottoms 16 of engraved as to produce different designs by.

the recesses 15.

The'inner ends of the handles normally abut the bottoms of the recesses and While rigidly to the roller vby turning the spindles,

ither one orvboth, to tighten the screws'.

A sleeve 22 closely ensheathes the roller 14, this sleeve being made of resiliently yielding material, as Vrubber or acomposition of free to turn on the spindles, may be clamped matter having similar properties, the sleeve being of. considerable thickness and provided with raised corrugations 23 disposed over its entire circumference.

These corrugations are disposed in irregular formations, uniform in depth but varying in surface area and shape as well as in angularity with respect to the axis of the roller and to each other, and are also of different lengths.

In operation the paint to be used in graining is applied in any convenient manner to the outer surfacerof the sleeve, when assembled on the roller, which is then inevedby means or' thehandles or otherwise in,y a direction generally lengthwise of the Vwork surface. -A n It has been 'found in practice thatElie best results are attained by having one of the handles loose with respect to the roller and the other tight so that a combined rolling and sliding movement may be imparted to the roller, thereby producing a Wide variety of designs Wholly impossible to attain by a roller which merely revolves upon its axis.

In addition to sliding movements, which are obviously limited in extent, the axis of the'roller may be inclined upon its axis from time to time, and to different extents as Well as in opposite directions.

tAs a further feature advantage may be taken of the yieldability of the sleeve, different pressures producing unlike effects, because of the spreading of the corrugations, so that, due to the described structure and the different Ways in which it can be inanip- Aulated, a limitless number of designs can be produced with a single roller and without change of sleeve, although changes in the sleeve may be made in an obvious manner.

From the foregoing it Will be seen that a simple device for this purpose has been disclosed in the preferred form of its einbodiment, but it is not desired to restrict the details of the exact construction' shown, it

being obvious thatchanges, not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A graining tool comprising a solid roller containing linger receiving recesses in its ends, and a resilient sleeve on said roller said sleeve having an irregularly corrugated surface.

2. A graining tool comprising a solid roller containing` an axial recess in each end, handles seated on the bottoms oi' the recesses, spindles adjustably threaded into the ends of said roller, said handles being r0- tatably mounted on the spindles, and a yielding sleeve directly fitting said roller, said sleeve bearing a raised design.

3. A graining tool comprising a solid roller having an axial recess ineach end,

posed of a series of irregular,angularly dispose gl, broken ridges of unlike area.

4l. A graining tool comprising' a solid rollei' containing linger receiving recesses in its ends, axially extending liandlesengageable in the recesses, means for securing either or both handles rigidly therein, and" corrugated sleeves interchangeably engaged directly on said roller.

This specification signed this thirtietli day of January, 1925.
