LATHING.

SPECIFICATION forming part of Letters Patent N o. 651 ,590, dated June 12, 1906. application filed December 21,1899. Serial No. 741,172. (No model.)

T0 at whom it may concern:

Be it known that I, FRANK E. BRIGHTMAN, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Lathing; and I do hereby declare the following to he a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which :0 it appertains to make and use the same.

My invention relates to improvements in lathing or skeletons used in the construction of fireproof walls, ceilings,partitions,&c., more especially, however, to the class of me- :5 tallic lathing or skeletons which when suitably secured in position forms the foundation for the filling which constitutes the body of such structures. In this class of lathing or skeletons it is of the first importance to combine with lightness strength and durability and to effect manufacture with facility and cheapness. Various forms of construction of lathing of this type have been produced, among them one having a twisted web with inclined convergent walled keys and the keys themselves arranged parallel throughout the lathing.

My present invention or improvement embodies a structure or lathing having alternating keys or cups throughout its area with the walls of all the rows or series longitudinally tapered and laterally inclined, but of alternating rows or series oppositely inclined, and the points of connection or union between them forming troughs or depressions in the median plane of one row or series of keys and ridges or apices in the median plane of the succeeding series or row of keys, the same alternating throughout the lathing, said depressions and ridges individually alternating diagonally, substantially as hereinafter more fully disclosed, andspecifically pointed out in the claims.

In the accompanying drawings,'illustrating the preferred embodiment of my invention, Figure 1 is a plan view. Fig. 2 is a section on line as w of Fig. 1. Fig. 3 is a section on the line y y of the same figure. Figs. 4 and 5 are detail sections taken on the lines w w and z s, respectively, of Fig. 1.

In carrying out my invention I construct the lathing 1 preferably from asingle piece of metal-light sheet metal. The peculiar construction of the lathe results in forming.

cup in its general outline is widest at its middle, as relates to its lateral area, and tapers toward each end. Taking the row or series of keys or cups 2 it willbe seen that they join or unite at theirlower or outer surface edges, as at 3, thus producing or forming what may be termed depressions or troughs in the median plane of the whole series or row, permitting the spreading or inclining outward or upward of the walls thereof throughout. In the row or series of cups or keys 2, alternating with the aforesaid row or'series of cups or keys, as above intimated, just the reverse is true, they being joined or united at their upper or inner surface edges, as at 4, said points of union alternating with the points of connection between the rows of cups or keys 2, thus forming ridges or apices, as it were, in the median line or plane of the series or row of keys or cups. The individual apices and depressions of the series or rows of keys or cups it will be seen alternate diagonally throughout the lathing. The walls of these cups or keys 2, united at their upper or inner surface edges, are thus caused to incline inward or downward, the walls of the adjoining series of cups or keys thus being oppositely inclined and serving to interlock the filling-in portions of the plaster or mortar covering the lathing or skeletons.

Viewing the lath from the standpoint of Figs. 2 and 3 it will be seen that each of the two contiguous Walls 4 of each series of keys .or cups extending from side to side, as indicated by the double-headed arrow, is undulatory or wave-like in parallel lines with the longitudinal section of said cups or keys in its general outline, with the points of connection 5 between said walls arranged in approximately the same plane or horizontal alinement, thus presenting the same general surface area from above and below; also, that the points of connection of the adjoining walls of one such series of cups or keys are at the inner or upper surface edges of said walls and that the points of connection between the walls of adjoining or successive series of cups or keys are at the lower or outer surface edges of said walls and the points of connection between. the walls of -the third series of cups or keys are similarly arranged as the first series of cups or keys, and so on throughout the lath; also, that by reason of this construction the series or rows of cups or keys are formed of the minimum amount of metal, only three instead of four walls,as would otherwise be required, being provided to constitute each two series of such cups or keys, and that said walls themselves are each of a uniform cross-sectional area throughoutand oftheminimumlightness or thinness consistent with strength,while the stretch imparted to said walls in forming the keys or cups does not affect or reduce the general surface area of the lath. This is due to the fact that each wall, as above intimated, is reversely inclined or deflected in the formation of each key or cup of all the series or rows-of keys.

It will be seen that the lathing or skeleton is thus permitted to be made of very light thin metal and yet possesses the requisite strength or body by reason of the angularity of the respective walls of each key or cup, this also being due to the alternate connection of the top and bottom edges of the walls ofthe cups or keys. It will also be observed that by means of the aforesaid construction of lathing or skeleton the same can be used with either side or face presented outward or reversely put into position, which thus expedites and facilitates the operation of applying the lathing or skeletons and avoids mistakes. It will also be seen that 9116 wall of each series or row of cups or keys forms the ad joining wall of each succeeding series or row of cups or keys, thus providing for the maximum utilization of metal and the greater number of keys or cups, increasing the efliciency of the plaster or mortar holding capacity of the lathing or skeleton.

Having thus fully described my invention, what I claim, and desire to secure by Letters Paten i 1, As a new article of manufacture, a lathing or skeleton having series or rows of keys or cups, the walls between which having theirpoints of connection arranged at alt-ernately-opposite upper and lower surface edges of said walls, substantially as set forth.

2. As a new article of manufacture, a lathing or skeleton having series or rows of keys or cups, the walls between which having their points of connection in approximately the same plane and said points arranged at alternately-opposite upper and lower surface edges of said walls, substantially as set forth.

3. As a new article of manufacture, a lathing or skeleton having series or rows of keys or cups, the walls between which having their points of connection arranged at alternately opposite upper and lower surface edges of said walls, said walls being oppositely flared or inclined from alternating points of connection, substantially as described.

4:. As a new article of manufacture, a lath ing or skeleton having series or rows of keys or cups, the walls between which having their points of connection approximately in the same plane and said points arranged at alternately-opposite upper and lower surface edges of said walls, and oppositely flared or inclined from alternating points of connection, substantially as described.

5. As a new article of manufacture, alathing or skeleton having series or rows of keys or cups, the walls of which are undula tory or wave-like and in parallel lines with the longitudinal section of said cups or keys and their points of connection arranged at alternately-opposite surface edges, substantially as set forth.

6. As a new article of man ufaeture, a lathing or skeleton having series or rows of cups or keys, the walls of which are undulatory or waverlike and have their points of connection arranged in approximately the same plane and at alternately-opposite surface edges, substantially as set forth.

7. As a new article of manufacture, a lathing or skeleton having series or rows of cups or keys, the walls of which are undulatory or wave-like in parallel lines with the longitudinal section of said cups or keys and have their points of connection arranged in approximately the same plane and at alternately-opposite surface edges, said walls also being oppositely flared or inclined from alternating points of connection, substantially as set forth.

8. As a new article of manufacture, a lathing or skeleton having series or rows ,of keys or cups, with the points of connection between the walls of said keys or cups arranged in approximately the same plaue and at alternately-opposite upper and lower surface edges of said walls, the walls being oppositely flared or inclined at alternating points of connection, all being formed in a single piece, substantially as set forth.

In testimony whereof I afllx my signature in presence of two witnesses.

FRANK E. BRIGHTMAN.
