. EXPANDED METAL.
certain new and useful Improvements in Expanded Metal; and I do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. v
This invention relates to improvements in expanded -Inetal and more particularly to improvements on my prior invention for metallic lathing, for which Letters Patent of the United States No. 642,056, were issued on the 23rd day of January 1900-. s Expandedmetal is much used not only for lath but also for constructing various structures in which concrete, plastely eement orother similar material is used to afford a finish. It is frequently very important where expanded metal is used for these purposes,that the same bend easily and symmetrically to adapt itself readily to the desired curve or curves of the structure,
thereby avoiding abrupt or angular bends, and also.
affording greater strength than where unequal strain is brought to bear upon the metal as is the case where such bends, are formed.
The object of this invention is to provide an expanded metal adapted particularly to conform closely 3 to either fiat orcurved surfaces and provided withi means for afio'rding a more certain clench for the plaster or filling material than has heretofore been possible.
The inventjbmcnnists of the matters hereinafter described and more-fully pointed out and defined in the appended claims; In the drawings; Figure 1 is a plan view of the outer side, or that, to which the plastering or' filling material is applied. Fig. 2 is an enlarged section taken on line --2--2 of Fig. 1. Fig. 3 is an enlarged section taken on line 33 of Fig. 1.. Fig. 4 is aplan view of the expanded metal seen from the rear or clench side.
As shown in said drawingsziA sheet of metal is slit in parallel staggered slits of a desired length and providing a uniform web of a desired width between parallel rows of slits. The sheet is then formed by supporting the integral; part between the ends of longitudinally adjacent slitson round toppedsupports, and by engaging on each side of the same in the slits means acting to force the cut edges downwardly. A rounded key Bis thereby formed as shown in Figs 3 and 4, the inner or concave sides of which, all open in the same direction as shown in Fig. 1. 'The webs are finally forced laterally causing the cut edges to diverge from their extremities in the generalplane of the sheet, thereby expanding the sheet intermediate of or between the adjacent keys B; and giving the webs a half turn or twist as indicated in Figs. 2 and 3 as in my prior Specification of Letters Patent. Application filed February 15, 1902, sealant. 94,211.
Patented July 30, 1907.
patent. At a point abreast of each key, the lower or slit margins of the webs connected therewith are turned upwardly providing relatively small laterally directed flanges b as indicated more clearly in Fig. 3.
When the sheet is expanded the webs afford great strength owing to their half twist or turn, while the curved or rounded portion or key also increases the strength of the sheet as a whole and permits the same to bend uniformly laterally thereof. Inasmuch as the middle portion of each web is practically in a plane parallel with the expanded sheet, the same while affording considerable rigidity is adapted also to bend uniformly longitudinally. When said expanded metal is made of a suitable size for lath, the same may be plastered on either side, but preferably on the concave side or that shown in Fig. 1, in which case the plastering material or cement fills through the shoot forming wedge shaped keys or clenches in the diamond shaped pockets between respective ridges, embedding the flanges b in said material and serving to increase the holding power of said clench, and at the same time entirely covering or embedding all the cut edges of the webs. a 7
Obviously, the expanded metal may be constructed of any desired weight and material or size of mesh, the larger sizes being adapted for use in concrete construction of various kinds. When so constructed, the lateral flanges b serve to afford a positive support for the concrete or other material in which the expanded metal is embedded and adds greatly to the holding power of the metal for the concrete.
Obviously, many details of construction may be modified without departing from the principle of ill) invention.
I claim as my invention:
1. A sheet of expanded metal comprising a slitted and expanded sheet having the webs thereof spread oppositely apart in the direction of the plane of the sheet and turned diagonally therewith and a laterally directed flange between longltudinnlly adjacent webs.
2. A slitted and expanded metal sheet having the webs spread apart in the direction of its general plane and rounded keys-between and connecting adjacent webs and inwardly directed flanges on said keys, said webs twisted laterally between the keys.
3. In an expanded metal a sheet slitted longitudinally forming parallel webs and expanded laterally, the cut ed es of said webs adjacent the extremities of the slit being turned obliquely to the general plane of the sheet, convex keys between and connecting adjacent webs, and an integral inwardly directed flange on each key.
4. A longitudinally slitted and laterally expanded sheet having the cut edges all directed laterally in the direction of the plane of the sheet, rounded keys connecting adjacent webs and convex on the sides opposite that from which the cut edges are directed and cdncave on the side opposite therefrom and a laterally directed flange on each key projecting into the opening between the keys.
5. A sheet of expanded metal having tli cut edges therevof forced laterally'in the direction of the plane of the sheet and having a lateral flange on each web said webs I being twisted at an angle with the general .plane of the- "sbet.
flange are embedded therein.
twisted at an angle with the plane of the sheet whereby 'when plastering material is appliedon one side of said 7. A slitted metal sheet alfording webs said webs expanded oppositely and turned at an angle with the plane of the sheet and a rounded key joining the ends of adjacent webs.
8. A. inetal sheet slitted andaffording rows of webs of uniform length, said webs expanded oppositely in the direo tion of the plan'e of the sheet and turned at an'angle with the plane of the sheet and keys connecting the ends of adjacent webs having inwardly directed flanges.
In testimony whereof, I have hereunto subscribed my name in the presence of two subscribing witnesses.
