After the ?nal coat of shellac and wax has 20 to form the letters or other characters and pro duces a sign in which the letters or characters dried to produce a smooth glass-like surface for will be set off in an attractive manner by the sand ' the plank, it is washed with naphtha gasoline to blasted background. remove dust and other foreign matter. A sheet ‘ Another object of the invention is the provision 25 of an improved method of making a sign which of rubber-like material used for making stencils’ is then applied to the prepared surface of' the plank and by referring to Figure 5 it will be seen. of expensive machinery and special training call ‘ that this sheet of. stenciling material, which is may be very easily carried out without the use ing for high price ‘labor. _ The invention is illustrated in the accompany 80 ing drawing, wherein Figure 1 is a view in front elevation of the im proved sign, a Figure 2 is a sectional view taken longitudinal 1y through the sign upon the line 2—2_ of Figure 1. Figure 3 is a transverse sectional view taken_ along the line 3—3 of Figure 1. Figure 4 is a fragmentary perspective view of a board coated with shellac and waxed and ready to have a stencil applied to it. 40 ‘ I Figure 5 is a view showing the stencil applied 'to the board. Figure 6 is a sectional view taken along the indicated by the numeral 4, is of less length and width than the 'plank. It will be understood, how ' ever, that if necessary the‘ sheet of stencil mate-v 30 rial may correspond _to the dimensions of the plank and that its_' dimensions will be governed‘ according to the number and location of the let ters or other characters which it is desired to have appear upon the ?nished sign. The sheet of stenciling material when about to be used ?rst has the fabric backing removed from it and this surface of the stenciling sheet is pressed tightly against the prepared surface of the plank. The stenciling sheet is applied before the naphtha it) gasoline has dried and, therefore, the rear sur face of the rubber-like material from which the stenciling sheet is formed will be softened slightly Figure 7 is a view showing portions of the and cause the stenciling sheet to adhere very 45 stencil sheet removed and‘ other portions of the tightly to the plank. Since the surface of the sheet forming letters remaining upon the board. plank to which the stenciling sheet is applied is Figure 8 is a sectional view taken along the smooth and highly polished, all portions of the stenciling sheet will adhere to it and formation line 8-8 of Figure 7. Figure 9 is a view showing the sign immersed of air bubbles between the plank and the stencil 50 in a mixture of varnish stain and banana oil ing sheet which would interfere with proper ad- 5' hering of the stenciling sheet to the plank pre after sand-blasting. This improved sign is formed from a plank I vented. The outer or front face of the stenciling which is cut the correct length and width and may sheet is now marked with outlines of the let be of any thickness desired. Surfaces of the ters or other characters which it is desired to line 6-6 of Figure 5. 55 plank are smoothed by planing and opposed side have appear upon the sign and the stenciling 2 2,100,000 sheet out along the bordering lines so that the stenciling sheet, with the exception of the out may then be applied to the sign either by dipping lined letters or characters, may be removed and it in a tank ?lled with lacquer or by means of a brush or air gun. In case-it is desired to have discarded. This step of the process is illustrated the letters stand out more clearly from the dark in Figure 7 and referring to this ?gure it will be seen ‘that the portions 5 of the stenciling sheet which remain adhering to the plank conform to background, they may be painted a desired color. This sign is very attractive in appearance and the shape or outline of the letters or characters to appear upon the sign and, in the present illus In the preferred embodiment of the invention, both side faces of the plank will be treated with shellac and waxed and the stencil sheet then applied to each prepared surface and cut out to form letters, 15 but, if so desired, only one surface of the plank may be treated and a single stenciling sheet 10 .tration, will- form the words "Sign Studio”. applied. ‘ After the stenciling sheet has been applied and the stenciling sheet cut and surplus portions 20 thereof removed, as shown in Figure 7, the plank with the letters or other characters of stenciling material adhering to it is subjected to the action of a sandbiast operating under a pressure of ap may be easily read as the letters standout very distinctly against the dark background which is apparently weather-beaten wood. It should also be noted that as a large portion of the soft grain has been removed by the sand blasting, the weight of the sign will be greatly reduced and it may be suspended from a light-weight support. As a large part of the soft grain has been re 1O moved and the coating of varnish stain and ba nana oil penetrates deeply into the hard grain and remaining portion of the soft, grain, this sign will stand exposure to weather as an out: door sign without being damaged by rain, snow and the like. ‘ _ I 20 While the sign illustrated in the drawing has alternating layers of soft grain and hard grain extending perpendicular to the faces of the proximately 100 pounds. The sand which strikes ' plank which are to be sand blasted and this ar 25 the letters of the elastic stenciling material re rangement is very desirable when soft wood such 25 bounds without cutting through this material, as fir, pine and hemlock are used, it will be un but the sand which strikes other portions of the plank cuts through the wax and shellac and into the wood from which the sign is made. The soft 30 layers of grain will be out faster than the layers of hard grain and, therefore, the layers of hard grain, which are indicated by the numeral 6, will project outwardly from the layers of soft grain, as shown in Figures 1, 2, and-3 and thus produce 35 a weather-beaten appearance. After the sand? blasting has been completed, the plank with the stencil letters still adhering thereto is immersed in a tank ‘I ?lled with a mixture of varnish stain and banana oil. This mixture, which is indicated by the numeral 8, is of such a depth that the en tire plank may be immersed therein and should consist of one-third banana oil and two-thirds varnish stain. The varnish stain and banana‘ oil is absorbed by the wood from which the sign is formed thus acting. as a preservative for the wood and also imparting a desired color to the derstood that the grain may run parallel to the faces to be sand blasted, the latter arrangement not being practical when soft wood is used but producing a very beautiful effect when the plank 30 is cut from hard wood such as oak, maple or “ ash. It will also be understood that any kind of wood may be used and that the choice of grain and the direction in which it runs is unrestricted. Having thus described the invention, what is 35 claimed as new is: v ' _.The method of forming a sign consisting of cutting a plank a predetermined length and width and smoothing faces of the plank, applying suc cessive coats of shellac to the plank to provide 40 smooth and highly polished surfaces for the plank and impart toughness to soft grain of the plank, washing the shellacked faces of the plank with naphtha gasoline to remove foreign matter, ap plying a sheet of stenciling material to a shel lacked face of the plank before the gasoline has sign, the color being preferably dark in order dried and‘ thus soften the face of the stenciling to add to the impression that~ the sign is formed sheet confronting the shellacked surface of the of weather-beaten wood. Attention is further plank and cause the stenciling sheet to stick 50 called to the fact that the banana oil penetrates closely to the plank, outlining characters upon 50 the letters of the stenciling material from the 'the outer face of the sheet of stenciling material outer faces and side edges thereof and softens and cutting through the stenciling material them so that when the sign is removed from the along outlines of the characters and removing oil bath they may be easily removed.
