' a P 627x 9 UNITED STAT PATENT OFFICE-e PAUL-A. esrALnEa-,,or PITTS URGH,,rEnNsYtvAn A,Assrenon r0 THE 0am VARNISHQCOMBA'NY, or CLEVELAND, OHIO, A conrona'rlonoronro V enarmne TOOL.
ances, and is particularly concerned with the,
construction ofa tool, which is'adapted to be simultaneously moved" and oscillated 1 too along the surface to be grained.
In grain-ing flat surfaces, particularly floors, it frequently occurs that the boards are uneven, and in consequence thereof, the
surfaces to be grained are not in thesameplane. Under such conditions it is 'difiicult to secure satisfactory results by employing a graining tool; which-comprises a rigid structure. i
An object of my invention is the pro-- visionof a graining tool which may be em-' ployed for graining'uneven surfaces, and for producing satisfactory results thereon,y-the' result being accomplished by makingthe body of the tool somewh-atfiexible or articulated, while at the same time, "it is stiff enough to prevent undue distortion of the grainingsurface on the tool.- Another object is the provision of a tool'having rel ati-vely' movable sections, whichare arranged to be moved selectively the operator dur ing the graining operation. r
In accomplishing the above objects, Ipro vide a tool having a head comp-rising a series of'sections which are movable relatively to each other and which are arranged to receive a suitable graining pad. FurthermoreI provide means forsecuring these sectlons 1n alignment with each other, and for.
allowing them to be selectively moved, while the tool, as a unit, is being drawn along the surface to be grained;
The means for accomplishing the, above objects will be more fully set forth in the following description which relates to the drawing, and the essential characteristics of my invention will be set forth in the claims.

'M'y invention, in general, contemplates the cprovision of a grainingi tool which en ables various portions of a graining' pad to be pressed-selectively-into engagement with the surface to be grained; The tool preferablyhas a segmental body tOaWlllCh is secured a graining pad 10 in the form of a ribbed" sheet'of rubber or: similar material positioned upon the arcuate bottom o-f the- The tool body comprises a pluralityof sections 11, which are shown as three in number, and as 'POSitIOD'GdadJaCBIIt each other-so; as tob'egcapable of' -being-" moved a" slight amountvertically and relatively to each other.- Each of the sections is preferably a block of wood'havi-ng recesses 12 on the upper surface thereof, for receivingthe first, second and third fingers respectively, of' the operator. The-blocks 11 are shownas secured together at the top-by means of flexible'plate, member or portion 13, which may be a strip -o'fjleather extending across the rope-feach sectionandrigidly secured thereto 1 That portionof the plate directly above the 're'cessesl2, may be 'cut away-tov permit the fingers" to" be inserted thereselectively exerted 'upon eachblo'ck. I The flexible 'rain-in-g surface 10, together with the fiexi bleqstrip 13,.servesi to retain the sections togetherand atthesame time to permit each section to be moved relatively to an adjacent section with-comparative case: It is obvious, however, thatthe vari ous sections may be held togetherby other means? for" instance, "the articulated "body may be made by taking a solid block and cutting part way therethrough so asto leave a narrow connecting strip between the adjacent sections, as shown in Fig. .4. This and other equivalent constructions are all included within my invention. The pre- The movement of the'hand, during the I graining operation is similar to the movement customarily utilized with the rigid form of block. Where portions of the surface to be grained are hollowed or uneven, then the operator may press more firmly upon that section immediately over the low spot, and thereby effect an even grain without stopping the forward motion of the tool.
From the foregoing description, it will be seen that I have provided a graining tool, which is quite simple in construction, and which is capable of being employed for satisfactorily graining uneven surfaces. Furthermore it will be seen that I have provided a tool which permits various portions of the tool to be selectively depressed by the operator, during the graining operation, without interfering with the movement customarily employed for such process.
Having thus described my invention, I claim:
1. In'a graining tool, the combination of an articulated body and a graining pad carried thereby.
2. In a graining tool, the combination with a graining pad, of a plurality-of sections positioned .adjacent each other, and means so connecting the sections that they may beindividually moved relatively to each other.
3. In a graining tool, the combination with the graining pad, of a supporting head therefor, said head comprising sections positioned adj acent-each other and movable relatively to each other.
4. In a graining tool, the combination with a flexible graining surface, of a supporting head therefor, said head comprising sections positioned adjacent each other and movable relatively to each other, and means whereby each section may-be moved relatively to another section, by pressure exerted thereon by a finger of the operator.
5. In a graining tool, the combination with aa flexible graining surface, of a supporting body therefor, said body comprising segmental sections positioned end to end, and means for connecting the sections so that they are movable relatively to each other.
6. In a graining tool, the combination with. a plurality of sections positioned side by side, a graining pad positioned on the bottom of said sections, and a flexible member positioned adjacent the top of said sections, whereby each section may be moved relatively to an adjacent section.
7 In a grainnig tool, the combination with a plurality of segmental sections positioned end to end, a ribbed rubber graining pad extending across the bottom of the sev eral sections, and a flexible member secured onthe top of the several sections, whereby each section may be moved relatively to the adjacent section.
8. In a graining tool, the combination with a graining surface, of a segmental body carrying the same and having individual finger recesses in its top surface.
9. In a graining tool, the combination with a graining surface, of a series of supporting sections having recesses therein,each of said recesses being adapted to receive a finger of the operator, and meanswhereby each section may be moved relatively to and independently of an adjacent section.
10. In a graining tool, the combination with a graining pad, of a series of supporting sections therefor, and flexible means associated with said sections for permitting them to be moved relatively to each other.
11. In a graining tool, the combination with a graining surface, of three supporting sections therefor, each of said sections having a recess therein and arranged to receive the first, second and third fingersrespectively of the operator.
12. In a graining tool, the combination with a flexible graining surface, of aseries of sections positioned thereabove, each of said sections having recesses extending downwardly from the top thereof, a flexible member positioned across the top of said sections and provided with aperturesin registration with said recesses, and means whereby each of said stctions may be moved relatively to an adjacent section by a finger of the operator pressing downwardly.
In testimony whereof, I hereunto aflix my signature.
