Afa/ffy Sway Patented Apr. 5, 1938 2,112,936 UNITED STATES PATENT OFFICE 2,112,936 SHEET METAL FLASHING Henry Sway, Cincinnati, Ohio Application December 11, 1936, Serial N0. 115,307 8 Claims. ’I‘his invention relates to an improved sheet surface of the wooden panel I, then extends metal flashing formed so as to make a new type down around the end or side of the wooden panel, stucco guard such as may be used by the build to the sheathing 2, thence at right angles away from the wooden panel flush with, and across ing trades for securing a Weathertight joint wherever it is desired or necessary to have stucco, or similar cementitious material, tightly abut wooden surfaces. Another object of this invention is to provide an improved type of flashing which will prevent the shrinkage of stucco away from abutting wooden structures as the stucco dries out, and/or prevent the cracking which occurs when wood (green) dries out and pulls away from the abut ting stucco. Another object of this invention is to provide a new means of conducting away moisture which the sheathing 2 for a short distance. A key ef fect is obtained by an outwardly extending rib 33 formed or bent in the sheet metal and pro r. jecting at an angle to the sheathing and dis posed substantially parallel to the wooden panel I. The sheet metal is then extended angularly back lí) lto the sheathing 2 and thence along for a short distance flush with the sheathing. The end of the metal flashing 3 may abut the lath 4, which is fastened to the sheathing 2 in any manner common in the art. The metal flashing may be fastened to the wooden panel I or to the sheathing 2, or to both, would otherwise be absorbed by the stucco mass as well as the wooden paneling, and which oftimes will seep into the inner plaster of a room by means of nails or small screws. spoiling it as well as the wallpaper on it. The ease with which this new type flashing it will completely lill up the space outside the., 20 metal flashing as well as the space in and around may be adapted to fit any shape opening or other type of flt where stucco and wood are to abut will be readily seen. The foregoing and other objects are attained by the means described herein and disclosed in the lath, so that when'drying occurs a key ar the accompanying drawing, in which: Due to the design of the metal flashing, the stucco on drying will be tightly wedged and held Fig. l is a perspective view of a gable embody ing the present invention. Fig. 2 is a cross-sectional view taken on the line 2_2 of Fig. 1. Fig. 3 is a View similar to Fig. 2 and showing a modified form of .the invention. Fig. 4 is a View similar to Fig. 2 and showing another modified form of the invention. The present invention is directed to improving the methods employed by the building trade in butt joining stucco panels with Wooden panels by means of an improved sheet metal flashing. Referring to Fig. 2, character I represents a cross-sectional view of a wooden panel, character 2 indicates the wooden sheathing used by the building trade as a base for the exterior surface of a building. It is to be understood that the - customary weatherproof paper, furring and metal or other lath may be used beneath and for affix ing the stucco, however, same are not shown in detail inasmuch as they are but incidental and commonly understood factors, the illustration of which is not necessary for understanding the present invention. Character 3 represents the sheet metal flash ing in position as a guard and comprises base 3D, outside flange 3I and side or intermediate sec tion 32. Said metal guard is ñtted over the outer When plastic stucco is applied to this surface, rangement will be formed with the metal flash ing. It is .to be understood that the rib 33 may be perforated to thus provide a key for the¿_ 25 plastic. in place by the key elïect of the bottom part of the flashing, and therefore the usual tendencyy 30 of the stucco to pull away will be greatly lessened, and further, the usual shrinkage of stucco from wood will be greatly diminished because by the use of this flashing the stucco is placed in con tact with sheet metal for which it has great. . aflinity, instead of in contact with the wood pan eling itself. Attention is directed to the fact that should some shrinkage occur between the stucco and the tight metallic weatherproof surface of seal the around flashing, thethere wooden is still panel extending down around the side of the panel, around under .the stucco over to the lath. There fore, should moisture or any of the other ele ments be driven into this opening, the injuriousy action of said elements is stopped by the metal flashing. In the event that rain would come in through .the opening between the metal flashing and the stucco, it will be conducted away by means of the trough formed by the metal ñashing and thereby it will afford an effective means of drain age for the abutting stucco paneling. Fig. 3 shows a modification of the metal flash ing guard just described. 'I‘he modification liesI` 55 2 2,112,936 in the method of anchorage to the wooden panel Having thus described the invention, what is I I, as well as to the method of anchoring the end of the flashing guard abutting the latch. A lip I6 is bent along the edge of the sheet metal flashing which ñts into groove I1 which is cut into the wooden panel to accommodate it. The metal ñashing is then brought across the outer face of the wooden panel and thence down at claimed is: 1. 'I'he combination with a building comprising sheathing, means of the class of lath for sup right angles flush against the side of the sheath ing I8, thence for a short distance across on the sheathing before being bent back over itself at an angle approximating l35 degrees with the sheathing, where it is terminated. This end is securely held in place by means of a metal cleat, I9 which abuts the lath 20. The advantage of this type flashing guard lies in the fact that there is a positive lock formed between the ñash ing and the outer surface of the wooden paneling. Fig. 4 illustrates another modification of the 20 two flashing guards just described, the distinc tion being primarily in that the metal flashing is anchored in the side of the wooden panel 2|, below the surface of the stucco when put on. In this manner the flashing is concealed from sight, 25 and cannot be detected from the outside. The metal flashing 23 is bent so as to form a lip 24 which fits into groove 25 which is cut in the side of panel 2|. This groove is cut so as to be below the outer surface line of the stucco in its com 30 pleted form. The metal flashing guard is then bent at right angles so as to be flush with the side of panel 2I and continued down to the sheathing 22. It is then bent at right angles back so as to» fit flush with the sheathing for a short distance to the key formation 26 which is formed by bending the flashing back over itself at an angle approximating 135° with the sheath ing, but it is not terminated here as in Fig. 3, but is then bent back on itself down to the 40 sheathing 22 which it parallels and is iiush with a short distance to abut the lath, where it terminates. In use the ends of these metal flashing guards will be so connected at the joints as to make a 45 weather-proof seal, and although kthe building trade has for a number of years been accustomed to provide water-tables wherever water would soak in over door frames, window frames, etc., this metal flashing guard provides a water-table 50 effect all around the joints wherever stucco and wooden paneling are to butt, and further it provides a tight mechanical bond on all surfaces heretofore unprotected. In those instances where the metal flashing is 55 exposed to the elements, it may be made of cop per or of galvanized sheet metal or other sheet metal and painted. Wherever the term “wooden panel” is used, it 60 is meant to include and embrace all instances where stucco, or similar building substances, is to abut wood trim or wooden work such as is found around Window frames, door frames` and the like and also to include, all cases where deco 65 rative paneling (wooden) is to abut stucco work. Whether the wooden panels are flush with the stucco panels, or whether they extend out from the stucco panels a short distance is immaterial. By carefully considering the description in 70 connection with the drawing, a clear under standing of the construction and application will be obtained. Changes in shape, size and rearrangement of details coming within the field of invention may be resorted to in actual practice if desired. porting a cementitious mass over the sheathing, 5 and trim exposed in part to the elements and having a portion disposed adjacent the sheath ing whereby to there provide a joint, of metal flashing extending over said joint, the edge of the iiashing adjacent the trim having element excluding contact with the trim and the portion of the flashing adjacent its otherv edge having a key forming rib therein for locking cementitious material to the iiashing. 2.
