GRAINING DEVICE.

Specification of Letters Patent.

Application filed March 4, 1907. Serial No. 860,655.

rimmed April 27, 1909.-

.To all whom it may concern:

position as to insure non-interference, as for Be it known that I, ALBERT LYNN LAW- example, by placing them at an angle witl RENCE, a citizen of the United States of Amerioa,and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Im rovements in Graining Devices, of which t e following is a specification, having reference as 1 well to the accompanying drawings.

My invention relates to improvements in grain'ing devices, and has for its object the pgoduction of such an appliance-which shall of simple and cheap construction, durable and readily used by anyone without experience.

This invention relates more particularly to a type of graining device possessing a flexible face, having a atter'n formed or molded thereon, adapte to be drawn or wiped over the surface to be grained, and. thereby producing an irregular pattern resembling the desired'variety of wood. In such an appliance, however, it is desirable to combine in a singletool means for combing the pattern,

a tubular or cylindrical grainer, but the patrather than to resort to a separate device, as has been done hitherto. I sirfableto apply two or more graining patterns Moreover it is deto this style of grainer, and in such manner that one will not interfere with the other. This general result. has been attempted upon terns necessaril 'are of short length, and

either lend litt e variation to the grained fisurface, or will' ii'iterfere with each other.

Such interference is not necessarily avoided so far as the comb is concerned, since this device almost invariably is subsequently applied to the grained-. attern. Again, itis hi hly desirable thatit shall be self-adaptab e to the graining of more or less irregular surfaces, and where the grainin surface is made of a high grade of soft rub er, a su'llioient body thereof will accomplish this result in some measure, but the cost of the comthe different patterns desired.

leted tool is thereby enhanced. Accordingl it has been my intent to combine in a sing e, simple tool, all of the advantageous features indicated, while avoiding the objections inherent in prior devices.

Briefly stated, my improvements consist in providing a backingor frame, preferably of sheet metal, over which is suitably formed or riiolded' resilient graining face bearing These grainone another, Moreover, the sheet metal frame preferably is formed with spring fingers, or is otherwise rendered resilient, in order to make the device self-adapting, in

large measure, and the whole is mounted upon a suitable handle for convenient manipulation. These, and other features, however, will be more readily gathered by making reference to the accompanying sheet of drawings, wherein Figure I is a triangular graining tool embodying my invention. the frame or metallic shell over which the Fig. II illustrates graining face is molded' Fig. III is a section through said shell or backing on line III-III. Fig. IV is a fragmentary view of the tool partially in section. Fig. V is a face view of one side the tool, partially broken away. Fig. VI is a top view of said tool, indicating by line I" the section shown in Fig. IV. Fig. VII is a top view upon somewhat smaller scale of a modified form of .lIlY invention; a portion of the graining face being broken away.

Throughout each of 'the several figures I have employed the same character Ofgdiglfifence to indicate similar parts. r

Preferably the device of my invention is .molded over a frame a of sheet metal, such as shown in Figs. II or VII, for example; the same being provided with one or more curved surfaces formed of resilient or spring-like fingers, formed integrally with a body portion of the frame, which in turn is mounted upon the handle. A suit-ably shaped sheet metal frame formed of the gage of metal affording su llicient body for applying the grain ing surface, ordinarily would present ,t 'r

polygon, as for example'the tween these lingers, lugs a may be formed,

which are bent u to assist in retaining the rubber in place, w iile the ends of said fingers or teeth may likewise be slightly turn'ediip for the same purpose, although this'j'i'snot r the necessary, particularly upon small tools. The fingers maybe corrugated. as at a to strengthen them somewhat, while in order to add to the resiliency, the corners of the metal v carded informing the "blank for constructing For example, 'in the o small device or Fig. VIL, these curved spring my improved device.

- \fingers are arranged in parallel'planes upon elther side ofa narrow flattened connecting portion. The central handle I; is rigidly secured by .means of a screw 6, and embedded Washer 11 to" said supporting frame, as best shown in Fig. IV.

Thedisposition of the several patterns is optional, depending upon the particular use for which the device is intended, but I have shown the employment of four different patterns, c, d, e, and f, the latter being a comb, While the others are arranged along the 2-5 curved sides of the frame. The covering or graining surface, preferably is molded from-a thin sheet'of rubber directly upon the frame, although r1 .1bber-compbsition, printers roller v composition, guttapercha and the like,inay be utilized. Since the body :ef the rubber maybe relatively thin, however, the ex pense thereof is not great, and a grade of rubber may inconsequence be used, which will resist alcohol, oils audthe like, without adding unduly to the cost. Graining pattern 0 is formed of interrupted or broken seg- 'ments, concentrically arranged and well adapted to simulate quartered oak. Pattern d is formed of concentric'ribs adapted for 40 simulating Georgia pine, and graining pattern 2;, comprises a('* uteedged and generally 'conntric ribs adapted'fbr the imitation of oak, while the conical rubber points f may admirably be used in lieu' of the comb for finishing the graining.

' An extremely adaptable tool conforming to my invention, is shown in the small view, Fig, VII, adapted to receive two graining 1 patterns along corresponding curved surfaces, with an intermediate comb. This deyiee is molded over the simple sheet steel frame a with the'rubber covering its entire area, and supported thereby, and although atterns are relativelyadjacent, it will 5 be noted that the comb" is intermediate of these patterns. Inasmuch as the comb is almost invariably applied, however, there s no opportunity for the one pattern to interfere with the other, and this devicenot only is cheaper to makabut is adapted for graining close to the edges of moldings and baseboards, or over simple moldings. 'It will be understood, however, that'my improvements sizes, embodying more, or less'ofthe severa era ass tric face in contact with the wet surface, and

forming the graining coat into a pattern 'resembling the desired variety of Wood. .comb is then drawn over-"the grained surface, and with alittle practice, close'imitations of different varieties of wood may be produced by any user of my im roved tool. It will be seen that t e edges of the graining patterns are unsupported, and by reason of the resilience of the metal, said patterns are rendered self-conforming to considerable variations in the grained'surface, without any attention whatever from the user. The sheet steel frame, however, permits sufficient pressure being applied, even with a large tool, 'to insure ample contactbetween the graining pattern and the grained surface for wiping the graifiing coat into the semblance of a natural pattern of the desired Wood; Inasmuch as the several graining patterns are disposed either at an angle to one another, or oppositely and distantly ositioned upon the frame, there is no possibi ity, of one pattern interfering or blending intoanother when this device is used.

The pattern may occupy the entire or only a portion of the curved surface of the device, as indicated respectively upon the right and left of Fig. VI.

Preferably a simple wooden handle b is centrally and rigidly-attached to the frame, as indicated in Fig. IV, or by the dotted circle in Fig. V II, but any suitable handle obviously may be employed, since my invention is not limited to the precise-means for practicing the same, herein set forth.
