M. L. CATON WOODEN BUILDING STRIP AND METHOD OF MAKING SAME Filed Nov. 16, 1927- 2 Sheets-Sheet 2 Patented July 14, 1931 UNITED STATES MAURICE L. CATON, or mnmroms, mnnnsofi- ASSIGNOR, BY imsNr: assmn- PATENT OFFICE MENTS, TO THE PATENT AND LICENSING CORPORATION, OF BOSTON, MASSACHU- SETTS, ACOBPORATION OF MASSACHUSETTS woonnn 3111mm s'rmr AND METHOD or Maxine sum Application filed November My invention belongs to that general class of products known as building material and relates more particularly to a wooden building strip or material particularly adapted for exterior use where the same may be exposed to the weather. Treated or coated -wooden shingles have been made heretofore, .but insofar as I know.the same have not gone into. use to any extent. While they have ad- 1 vantages over uncoated shingles'or over composition roofing in some respects, the advantages have not been suflicient to overcome the additional cost of manufacture andthe cost of laying. My improved product has the advantages of all previous types and additional advantages without any of their drawbacks. In the preferred embodiment of the invention, the body part or base is of assembled wooden boards/or equivalent mate'- rial, wooden shingles of the conventional shape being shown for purposes of illustration. The invention has among its objects the improved method of making and the production of a product of the kind described and economically constructedof inexpensive materials which may be inexpensively laid, and which generally will not have a tendency to check, warp, or split in use when-exposed to theweather, and which may be used wherever found applicable. The same has as a further object aproduct which will-be ex-.-

ceedingly attractive in appearance when .applied, and be of a desired color or combination of colors. in set forth is a fire retardent and under ordinary circumstances may be considered as fireproof, and which may be easily and convensame will lay moreor less flat, will not have the usual tendency to curl or turn up or be lifted by wind, and when properly installed objects and advantages of the construction which is efficient in use, may be inexpensively The same when made as hereiently laid to produce desired effects. The

purposes be leak-proof. In addition, it is w, 1927. Serial No. 233,045.

Referring to the drawings in which several embodiments of the invention are shown, it may be mentioned that preferably the body or base of my improved material or product is wood of the desired size and shape and of the particular kind of wood best suited or adaptable for the purpose. While the type of body or base is immaterial for purposes of illustration, I have shown the strip made Fig. 9 is a similar view illustrating another up of the familiar type of cedar shingles, these being comparatively inexpensive, particularly, as I am enabled to usethe inferior and cheaper grades of shingles. Shingles of this kind are of suitable lengths andv usually of varied width, thesame being tapwooden body, regardless of the size, shape or particular kind of wood, andimmediately thereafter impregnate the same with a light bituminous roduct, creosote, oil or the like, which will 1 up the pores and prevent the re-absbrption of moisture. Inthis treatment,

. however, Ipreferto use a substance of a boards are viscosity which will permit it to easily, thoroughly and efliciently penetrate the wood. It may be mentioned that I have not shown herein apparatus for carrying out the methods herein described in manufacturingthe product asthe apparatus forms the subjectmatter of a separate application, any suitable apparatus belng" adapted for the purpose.

There may, of course, be instances where the wood is entlrely free from moisture and where the further steps in the manufacture take place in the mill, and in this instance it may not be necessary as an initial step to dry the shingles or to saturate or impregnate the same to prevent absorption of moisture. But even then it is often desirable and I generally prefer to so initially treat them.

that the wooden shingles or V in satisfactory condition as regards being free of moisture, -I apply a coat- 7 I mgto the same of an appreciable thickness.

I have found satisfactory a coating of bituminous matter such as coal tar, pitch or asphalt compounds, or other egpiiwalent' material which constitutes a protecting celating, as well as a binder. This may be do e before or after the shingles have been assembled in form'as will hereinafter more partic arly explained, the time of assembly depending on the manner in which they are secure orjcemented together? This coat-- ing may cover the entire shingle or board,

faces, side edges and ends, or it may cover -onl'y such portions thereof as desired, it

being preferred to coat all surfaces that may be exposed,- or open to the air and weather and between the assembled shingles. Over this binder or coating orsuch portions thereof as may-be desired, I thenap- 1y a face coating or surfacing,and for this I prefer tofuse a mineral matter suchas crushed slate or' anite or stone, sand pebbles or slag of. the esired size of particles and here to each other. Of course, after thesame is installed, this is not material as the more they adhere or stick. together the better the finished prodhct will be. To so cover the ex posed portions of the vbituminous material and prevent sticking, I have found that talc,

mica or other substances may be employed, orv

paper or other separators may be placed between them.

In the drawings, I have illustrated several embodiments of the invention and arrange" ments of boards assembled together to form a strip which is substantially a unitary structure.' Referring first to Fags. 1, 2 and 3, 1

represents a wooden shingle suitably treated, if necessary, to remove moisture and prevent its further admission. In these figures two shingles are shown connected together by a fastener 4, the same also serving as a spacer between the two. Obviously one or more may be employed at each joint and any equivalent device may be used. Applied to the shingle as sho wn in this instance, over the top and bottom faces,-edges and butt end, and between thefshingles, is a coating 2 of asphalt or other bituminous product or the like which is of an' appreciable thickness and which encloses that portion of the base or body which is ordinarily exposed to the weather as well as fasteners 4. Over the part-that is exposed to view at least, I apply ding the particles of the surfacin into the coating so that they are firmly hel 'Where humps are desired for ornamental effect, the same may be left- This coating is applied at least to the top face and the butt end and may be invsome instances applied to the exposed side edgesn While in most cases I do not prefer to apply it to the under-face, this is a.- matter of preference. The under-face if not so surfaced but covered with the coating 2 may be covered with talc or the like so that in handling or.shipping they will not stick. together as previously mentioned. Obviously these large shingles or strips may be laid, similar to an ordina'ry shingle, with the coated and. surfaced butts exposed to the weather.. I

In Fig. 4, I have illustrated a modified 1 .together to form a strip. In this figure, 1 represents a shingle provided with the coating 2 and surfacing 3. Theseveral shingles may be secured together by Suitable 5 strips 6 of metal or its equivalent, there i being one or. more on the top. or one or more on the bottom or on both top and bottom. It may be mentioned that if metal straps are used, these may be applied in advance of the coating so that they are entirely enclosed and protected from the weather and are. also concealed. They may be applied by means of tacks, nails or the like, but in the form illustrated they are providedwith integral struck out prongs 7 which may be forced into the material,.serving the same purpose as nails. Obviously strips so constructed may be made as longas desired and either applied full length or the same severed to give desired lengths. In this case, as will be noted by reference to Fig. 5, the coating 2 may flow betweenthe shingles, serving as a binder, to hold them together, as well as sealing the joint between them. Obviously the coating and surfacing insofar as the exterior is concerned, affords full protection to the shingles. If the shingles are not brought tight together but slightly spaced, the joints may be apparent and afi'ord a pleasing appearance.

In Fig. 7 I have illustrated shingles similar to Fig. 1, except in this instance-the \fl, coating 2 encloses the entire body, the surfacing 3 being shown as arranged similar to that s'hown in Fig. 1. I have illustratedat 3 how the talc or other substance may be applied to coating 2 to prevent the shingles sticking together prior toapplication. Obviously there would also be talc on the under- 40 face. The .strip shown inFig. 4 or in the other figures hereinafter described may be ,made up of shirigles similar'tothat shown in Fig. 7 with the feathered edges all coated if so desired. I

In Fi 8 I have shown shingles or bodies 11- whic are substantially similar to those I shown in Figs. 1 or 7. In this case 13 represents a sheet of paper or other suitable material, 1 1 the binder applied to the sheet, the shingles being appliedthereto and secured to:13 by the'bmder. one of the various y kinds of paper that may be found suitable for the purpose may be employed. The top face and butt edge are coatedwith a coating 12 t5 corresponding to 2 and the surfacing 3. Or-

dinarily between the shingles only the bituminous binder is present, but the outside edges of the strip may be surfaced'if so desired. Obviously theextent of coating the 0' top face of the shingles or applying the surfacing maybe as 'prferredas I reviously mentioned. In making up this sty e of strip, I ordinarily prefer to-ap 1y a coat of the desired thickness of the inder'14 on the" 5 sheet 13, thence applyingthe o e ifi desired size and with a desire members 11, followedbythe enclosing coat 12. The coating 14 binds the bodies to the sheet and the coat 12 flowing between the bodies not only binds them together but forms a bond with the coating on the sheet. Obviously, the coating 12 may be applied to the entire top face if so desired;- The next step is the application-of the mineral surfacing coating 3. Pressure is preferably applied so that the particles of the surfacingcoat are embedded in the coat 12. Of course, in some instances the surfaclng and coating 12 may be applied. simultaneously; but thisv is ordinarily not preferred. It may be mentioned that while the body members are shown comparatively close together, they mayJoe slightly spaced from each other, this being particularly desirable if the two coatings 12 and 3 are applied at the same time. While ordinarily the binder or coats 12 and 14, together with the sheet-12, are suficient to hold the several bodies in the strip form, fastening means similarto that previously described or its equivalent may be additionally used if preferred. If desired to have a combination of color effects, as for example, alternate red and green in a single strip,

it may be preferred to so coat and surface the individual bodies prior to arranging and se curing them together.

In Fig. 9 I have shown a'somewliat similar arrangement except there is applied a second sheet 15 on the top face at the featheredge of the strip. This figure also illustrates how the butt edges may be sawed or out in fancifulfashion or otherwise formed to produce a pleasing effect. The particular shown is merely for illustration, it being obvious that it may be varied if desired. The trimming of the butt end would preferably take place at an early step in the manufacdeslgn' ture, so that the coating would cover theend as formed. In some instances the bottom sheet might be omitted and a coated and surfaced sheet be applied to the coated top face of the bodies. i

In Fi .11 I have illustrated how the strips 20 may e formed with an irregular shaped butt edge 21 so that when the strips are applied a thatchedeifect is: secured. InFig. 10, '17 represents a strip, for instance, paper, and in this case the shingles are arranged staggered so that the butts 19 are not inal' ment. The opposite edges may be sawe or trimmed straight it so desired, In other respects this strip may be constructed similar to the strips shown in the preceding figures. Obviously, very striking eifects may be obtained-in installing these types without increased expense in laying.

It is seen from the preceding'that the product may be made in the form'of'a'strip made up of a pluralityor desirednumber ofshingles' or boards to give a unitary strip of a.

contour of 1:0

' or sparks and yet give an ornamental effect which it is not possible to secure with the usual woodenshingle or siding or many other types of-coverings. The same is durable and of long life, and obviously having been once installed will not require painting or other treatments to preserve the wood. Many different colors may be employed, this depending upon the coloring of the surfacing coating v so that permanent ornamental and decorative effects not heretofore possible to obtain with wooden boards or the like are secured. The elastic bituminous or like material which encloses the wooden base or body will elimi nate or at least cover any cracking, checking or warping that may occur in the wooden o cay'ing. Likewise the insulating characteristics of the wooden base are improved, there-' by resulting; in increased efficiency. When ordinary shingles or boards are damp or full of moisture, the insulating value is re-, duced, hence with my improved product,

which cannot absorb moisture, the wood base or body is always eflicient as an insulator.

Where a sheet is'provided as a backing, its

insulating qualities are further increased.

Obviously the most suitable type of paper or other material may be employed to give the highest insulating efiiciency possible. The same when made up in strips may be laid in larger units than possible with ordinary product as these do not constitute a part of boards'or shingles, thereby reducing expense of laying, orlaid in art designs without increasing the laying cost; The great reduc-' tion in cost of labor for applying to either roof or side walls in new or old construction is one of the prime objects of this invention.

Likewise it is possible to use a multiple of small .or narrow widths or lengths of products or poorer quality of the same which are now of little value owing tothe inferior qualityand the great cost of labor for applying. There is, therefore, a'material saving in material cost and inlabor.

As mentioned before, I have not considered it nece'ssar to illustrate herein suitable apparatus or machines for manufacturing the the present invention. In the claims herein I refer to a filler which I wish to be understood as any filler suitable for the purpose parting from the dy and prevent or retard rotting and 'dethence applying a plurality of bodies .of impregnating the wood, and where I refer to a coating I wish also to be understood as a coating of any'suitable material and whether applied over all or only a portion of the faces, edges or ends. I also desire where I use the word surfacing to be understood that any mineral 0min, product may be em- I refer to a wooden base or or shingle, I wish to be undertions may be made in the same without despirit of my invention; hence I do not wish to be understood as limitmg myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

hat I claim as new and desire to secure by Letters Patent is:

1. A method of making a strip ofbuilding material consisting-in nous or like material to aJsheet of paper,

thereon, thence trimming the bodies at one end, and thence applying a heavy coat of bitumi nous material to'the flowing the same between the bodies to the sheet below.

2. A method of making a strip of wooden building material consisting in applying a bituminous or'like material to a sheet oft paper, thence associating a plurality of shingles therewith with slight spaces between them,'.thence trimming the shingles to a de-- sired contour at one end and thence applying a heavy coat of bituminous materials to the exposed face and ends of the shingles and between the shingles to the sheet below, thence applying a finishing coat of mineral and embedding t e same'in the heavy bituminous coating, thence applying means to the exposed bituminous material coating to prevent strips adhering to each other prior to installation.

between said wooden members and covering said spacing member. g In testimony whereof, I have hereunto signed my name.
