To all whom it may concern:

Be it known that I, GEORGE CRUM-v veneer strips of `suitalole length tired at in-` tervals to space `blocks or spacing devices and to have the strips `primarily separated to :term key ways forja plaster covering.

A further object of the invention is to provide a lath composed of veneer `strips held in fixed spaced relation and wherein the strips are disposed at an angle so as to produce key openings that will have the best eil'ect in positively securing a plaster covering applied over the lath and securely hold the plaster covering in different directions or to resist weight strain both vertically and transversely and thus prevent cracking and falling away of the plaster covering from the improved lath.

The improved laths may be either angularly disposed relatively to a horizontal plane or they may be arranged horizontally straight, and in some instances it is desirable or preferred that the laths be alternately arranged so that the angular strips thereof will be in reverse positions and give a greater resistance to cracking or displace-y ment of the plaster covering, especially on ceilings. l/Vhen the laths are applied the edges are exposed at the front and the lflat sides of the strips comprised in the lath organizations form the walls for the keys.

Another feature of `the improved lath is that they may loe telescoped at the ends and thereby rendered adjustable to accommodate variations in the distance apart `of studding and be secured by any suitable fastening means extending thereover at the joint and against a stud, or simply fastened with a large headed nail.

Among other advantages of the improved `lath are that it canbe used on a {'lat surface,

perspective view showing the improved latlr applied and illustrating the strips of the laths as disclosed at an angle to a horizontal plane `and the angles of adjacent strips in reverse positions. Fig. 2 is a view similar to Fig. 1 showing the laths composed of strips at angles to a` horizontal plane and the strips of adjacent laths in the same angle relatively toeach other. Fig. 3 is a view similarto Figs. l andQ showing the lath composed of horizontally straight strips. Fig. 4 is a transverse `vertical section taken in the plane of the line 4 4, Fig. 1. Fig.` 5 is a front elevationof la portion ofthe lath asshownbyFig. 1. l j

The numeral 5 designates a studding arranged as usual, and it will be understood that in the erection of a wall to which the lath is applied the saine organization of.4

framing will be adopted as now commonly l arranged at an` angle to a horizontal plane y and separated equal distances by space dc- `vices 8 While it is preferred to use veneer strips 7 and blocks 8 `in the organization of the lath, it will be understood that similar strips might also be associated with` any other spacing device adapted for the purpose and suitably secured to the strips. Vhatever may be the organization oit the strips and space devices, the ends ol. the

.strips at the opposite extremities of the lath are` extended beyond the nearest series of space devicesso that the extremities of contiguous laths may be telescopically interfitted as at 9, the laths thus being rendered adjustablcto compensate for variations in the distance between studding as often occurs in rapidly erected building structures. The laths are arranged edgewise against the studding or other supporting means therei for, and when the ends of the laths are joined or intertted, as shown by Fig. 1 for instance, a securing strip, such as a twisted wire or other analogous device l0, is appliedthcreover and nailed `or secured by astenings 1 1 which are driven through the wire or securing strip and also through spaces of the laths, and When this securing Wire or strip s applied over lthe jointed ends of the laths, a very firm and reliable application of the laths results.

As shown by Fig. 2, the laths maybe so applied that the strips 7 throughout thev Whole series of laths may have `thesameA angle of inclination relatively to a horizontal plane or all be in the same angle. lt will be found, however, very advantageous to arrange the laths as shown by F ig. l and wherein the laths are alternately disposed so that the strips 7 thereof will be at reverse angles, and by this means a su perior key organization is produced that will be a decided advantage in holding the plaster covering l2, as shownby Fig. el, in association with the laths and prevent cracking and loosening of any part of the covern ing and also more positivelyy oppose any tendency of the Weight strain 'of the plaster covering to fracture.`

ln the form ofthe lath as shown by Fig. 3 the veneer strips i3 are spaced through the medium of space devices 14, but the strips are horizontally straight.` While this form of the lath has been found practicable for many uses, it is not as positive in its action as the form of lath first described.

ln all the forms of the lath as shown, the edges of the strips are exposed and the flat sides of the strips produce the Walls for ther keys that are formed by the exposed key openings, thus providing a strong structure and at the Sametime forming a more positive key producing means, particularly as compared to the ordinary flat lath which gives a considerable exposure of lath body with a comparatively small and impositively operating key opening. y

rhe preferred method of manufacturing the improved lath is to build a stack of alternate layers of sheets of veneer and sticks extended across the Width of the sheets of veneer, the Whole being glued preferably with Waterproof glue. The sheets of lath are then cut off to form the strips by any suitable mechanism and the sticks are simultaneously cut therewith. rlhe lath Will be made in lengths to cover three or four studs, the preferred length being about fiftytvvo inches. Tie additional length of the improved lath as compared With the usual length of Wood lath provides for the telescopic association of the ends of the laths and an adjustment thereof to accommodate irregularity of spacing of studs. lf desired the lath may be increased or decreased in Width and length and other modifications in the details Within the scope of the invention may be adopted to accommodate various applications or uses of the improved lath.

llhat is lclaimed is: l. A lath consistingv of a plurality of 'thin strips having their flatsides arranged 3. The combination of laths consisting of thin strips arranged vvith their flat sides in superposed relation and provided With means for holding them fixed distances apart, the opposite extremities of the strips of adjacent laths being telescoped with relation to each other and adjustable, and means for securing the laths in applied position.

il. The combination with a Wall o; other support, of a series of laths each compris ing a plurality of thin strips having their flat sides in superposed relation and their edges exposed for the applicationl thereto of a plaster covering, the strips being provided With devices to hold them in fixed s'oaced relation, the strips being at an angle to a horizontal plane and the adjacent laths having their strips at reverse angles, and

key Ways means for securing the laths to the Wall or other support.

ln testimony whereof l have hereunto set my hand 1n presence of two subscribing Witnesses.
