TILE SUPPORTING STRIP Filed NOV. 19, 1934 Patented Oct. 20, 1936 UNITED STATES PATENT OFFIQE TILE SUPPORTING STRIP Application November 19, 1934, Serial No. 753,676

11 Claims.

This invention relates to a device for fastening roofing tile in place on a roof structure, and more particularly pertains to improvements in tile supporting hangers of the type disclosed in a copending application for United States Letters Patent filed February 26, 1934, Serial Number 712,923.

An object of the invention is to provide a tile hanger adapted to serve as a connection between .an anchor engaging a roof structure and wire ties engaging roofing tile to form supports for the tile, in which the hangers are so formed as to be adapted to be fastened at intervals throughout the Water shedding surface of a roof in such :cfashion as to prevent or minimize leakage.

Another object of the invention is to provide a roofing tile hanger which is especially applicable for use on membrane covered roof structures Where it is desirable or necessary to effect fastening of the hanger to the roof structure by nailing thereto through the water shedding membrane.

A further object is to provide a construction in the hanger whereby when the latter is applied to a roofing membrane by nailing the puncture formed in the membrane by the nail passing therethrough will be thoroughly sealed against possibility of leakage, and in which the hanger is so formed that when subjected to strains imposed thereon. by the load of the tile suspended therefrom a portion of the hanger will be caused to be. maintained disposed against the membrane above the point ofpenetration of the nail in such manner as to afford a tight seal.

Another object is to provide a hanger of the above character which is adapted to be employed in conjunction with tile supporting strips of the type formed with a series of. longitudinally spaced extruded loops in effecting connection between a roof surface and an intermediate portion of the strip.

Various additional objects and features of the invention will appear and will be more fully understood from the following detailed description of a present preferred embodiment thereof, reference for this purpose being had to the accompanying drawing, in which:

Fig. 9 is a detail in perspective illustrating a modified form of the invention and depicting it as applied.

Referring to the drawing more specifically, A indicates generally the tile hanger which is here shown as embodying a plate 8 of sheet metal formed adjacent one end thereof with an extruded loop 9 which projects from the upper or outer face of the plate and extends longitudinally thereof. The plate is formed adjacent its other end with a semi-spherical protrusion l0 projecting from the upper or outer face of. the plate to form a recess I I on the back or under side thereof, as shown in Figs. 1 to 8, inclusive.

In forming the loop 9 the plate A is subjected to the action of a punch and die mechanism whereby a pair of parallel slits l2 and [3 of corresponding lengths are formed longitudinally of the plate and the material of the plate between the pair of slits is pressed outwardly to form a loop. In order to strengthen the extruded loop thus formed the material thereof is formed of arcuate cross section as particularly shown in Fig. 4 with the upper side or face of the loop concave and with its under side convex. The loop is also arched longitudinally and thus has imparted thereto a double arch construction throughout the length thereof in a fashion corresponding to the formation of the loops in the construction shown in the application for Letters Patent above referred to.

The loop converges inwardly from its ends to its mid-length as particularly shown in Fig. 1 thus forming the loop of a width slightly less than the width of the slot l4 formed in the plate on extruding the metal extending between the slits l2 and [3. By thus narrowing the loop it is possible to insert it through a slot having a width corresponding to the width of the slot I l. The protrusion I0 is formed with a central opening l5 for engagement with or by an anchor such as a nail 16.

In the application of the invention, as shown in Figs. 5 and 6, the recess II is filled with a plastic material ll, such as tar or asphaltum preferably at the time of. applying the hanger to a roof, and v the hanger A is applied to the surface of the water shedding membrane i8 covering the sheathing l 9 of the roof structure; the hanger A being arranged to extend longitudinally in the direction of the inclination of the roof.

The nail IE is passed through the opening l5 and through the plastic El and is driven into the sheathing through the membrane 58 until the head of the nail abuts against the outer face of the protrusion 55 around the margin of the opening 55 and in such manner as to force the upper end portion of the hanger A tightly against the outer surface of the membrane 58, and in some instances partially embed the upper margin of the hanger A in the membrane. In this operation, a portion of the plastic body ll will be forced outwardly around the margin of theupper portion of the hanger A and also through the opening l5 around the head of the nail l6, thus securely sealing the areas adjacent the nail hole through the membrane l8 against leakage. In some instances the hole 45 may be formed by driving the nail through the protruding wall of the recess 5 l A series of the hangers are thus attached to the roof in suitable spaced relation throughout the area thereof.

In tiling the roof, the arrangement shown in Fig. 5 is preferably employed, that is by laying a row of pan tile 20 on the roof surface with adjacent tiles spaced suitable distances apart and with contiguous pairs of the pan tiles secured by tile supporting wires or ties 2! to the loops 9 of alternate hangers A, and then arranging cover tiles 22 to overlap the adjacent tiles of each pair of pan tiles and connecting the upper ends of such cover tiles by ties 23 to the loops 9 of the hangers A to which the pan tile supporting ties 2! are connected. A cover tile 2 iis then positioned to overlap contiguous tiles of adjacent pairs of the pan tiles, and is connected by a supporting tie 25 to the loop 9 of a hanger A interposed between or disposed adjacent the hangers to which pan tiles 20 and cover tiles 22 are connected as shown in Fig. 5.

The ties leading from the hangers and connecting with the cover tiles lead on an upward incline from the loops 9 to their points of intersection with the tiles, whereby the weight of the tile effects an upward pull on the lower end of the hanger A tending to rock the latter with the head of the nail 56 as a fulcrum in such fashion as to impart a downward pressure upon the upper end of the hanger A tending to force the latter into snug and tight contact with the membrane i8. This depression of the upper margin of the hanger A insures against the latter being tipped upwardly such as to permit ingress of water beneath the upper end of the hanger, and by this arrangement such bending of the nail I6, as might be occasioned under the load imposed thereon will not interfere with the seal afforded by the upper end of the hanger where it contacts the membrane 58. However, the dome like protrusion m is formed to project close to the fiat upper face of the hanger A so that when the nail E6 is driven in place, the upper or protruding portion of the shank thereof will project but a short distance from the upper face of the sheathing !9, and by use of nails of sufficient strength, little or no bending of the nail will occur, and consequently no enlargement of the perforation made by the nail in the membrane I8 will be apt '0 take place.

The hanger A is especially applicable for use in affording a connection between intermediate portions of the water shedding roof surface and.

tile supporting runners 26 of the type embodying a series of extruded loops 2?, as shown in Fig. 7; the hanger A being afiixed to the roof as before described, and as shown in Fig. 6, so as to extend longitudinally in alignment with the runner 26 and so positioned that the loop 9 will extend through the runner into engagement with a loop 27 of the. runner so as to nest therewith from the under side thereof, whereupon wires or pins 28, or other suitable fasteners, are passed through the interconnected loops of the hanger and runner thus effectively tying the hanger to the runner; it being understood that the hangers 25 are ordinarily afiix-ed only at their upper ends under flashing and are not designed to be secured at points in the water shedding surface of a roof.

Manifestly the hanger is applicable for use in affording a means of securing various forms of tile, slabs, and the like and of other forms of runners and the like to roof surfaces, than as here shown, and accordingly we do not limit ourselves to the particular usage here shown, and furthermore we do not restrict ourselves to the exact structure herein set forth but consider that the invention contemplates any structure coming within the meaning of the terms of the accompanying claims.

For example the hanger may be employed in the construction of tile covered concrete roofs which ordinarily are not provided with a surfacing membrane. In this instance a nail-"1f! or simi-- lar anchor is imbedded in the body of the concrete at with a pointed end protruding upwardly therefrom as shown in Fig. 8. After the concrete has set and in readiness for reception of the tile covering, the hangers A are put in place by applying plastic to the recesses H and then inserting the upwardy protruding pointed ends of the nails 30 through the openings l5 whereupon the nails are bent or clinched over the protrusion H3 in such manner as to tightly secure the hanger in place on the concrete slab. In like manner anchors 30 may be imbedded in a hardened concrete. roof by drilling holes in the concrete and thereafter cementing the anchor therein to provide the upwardly extending projections for engagement with the hangers.

Furthermore in some instances the plastic receiving recesses l I may be dispensed with and the upper end portion of the hanger formed with an opening l0 shown in Fig. 9 as where the hanger is to be nailed to a roof structure in a. position where the upper end portion thereof maybe covered by flashing or the lower edge of an overlapping layer of membrane 32. In this instance the use of aplastic or cement around the nail hole in the under membrane is not essential since the overlying membrane 32 serves to afford a covering for the nailed upper portion of the hanger in a fashion which will provide a seal for the nail hole. However, in this instance a plastic such as tar may be applied over the nail head previous to the application of the overlying membrane.
