Patented Oct. 25, 1938 i UNITED STATES PATENT yoriiflc'ziz THEREFQR y *o William H. O. Ness, Los'ngeles, Calif. lApplication September 25, 1937, Serial No.l 165,708 12 claims. 101. 10s- 26) This invention relates to an improved means for securing in place and rendering weatherproof the outer edge portions of sheet roofing materials.

.The invention is more particularly intended for use on buildings with at roofs surrounded by a parapet wall having a reglet to receive ashing Which overlaps the outer edges of the body of'sheet roong material applied'to the building; but it may be found feasible to use in other situl ations the combined flashing and releasable secure ing means provided by the invention Among theobjects of the invention are to provide a ashing and releasable securing means therefor that can be readily put in place without S; the use of tools and which will securely remain in place `upon the building until sucha time as it Imay-be deemed desirable to release it, when it may be readily released and 'removed Without the use of tools; to provide a flashinglocking maand releasing means of an exceedingly simple character which can be manufactured at a low a cost and will nevertheless be of a stur-dy, durable character; to provide a securing means for roofing paper that will beneat in appearance as Ywe11 as effective in its weatherproong features.

and which will therefore be particularly desirable to use on roofs provided with roof gardens and penthouses; and to provide an improved cooper.-

ating sheet metal key and sheet metal haspto4 301perform the locking and releasing functions. ,t

Other objects, advantages and features of in-` vention will hereinafter appear.

Referring to the accompanying drawing, which illustrates what is at present deemed to be a pre-r ferred embodiment of the invention, Fig. 1 is a sectional perspective illustrating the constructing of a cementitious wall having the reglet provided by the invention built thereinto.

.-Fig. 2 is a sectional perspective showing the invention in use as a ashing and locking means therefor applied to theparapet wall.

Fig. `3 isa cross section further illustrating the f As viewed in cross section saidgroove is of a truncated wedge shape, the mouth portion there- 550i being narrower than its base portion. vThis constructionresults in the'upper-'and lowerj'sides of said groove constituting shoulderslwhich wouldn prevent the regletrom being withdrawn through' the mouthrofthe groove even'if said :reglet were not'cementitiouslybonded to saidgroove atv the time of the building of thewall. v The reglet strip-12 -is: syr nmetrically shaped, its upper edge being furnished withaninwardly and downwardly directed hook portion IE5 while itsv lower edge has alike upwardly and inwardly directed hook portion I6; this `construction mak* ing -it unnecessary; to guard ,againstfpositioning the reglet wrong side up whenthe same is built into the wall. i s Y Sheet yroofing material 20 is shown in Fig.. 2. having anupwardly .directed edge portion 2|.

.Said edge portion r2'Igis2 protected by a Ystrip of flashing v22 madeofstiff sheet material, preferablyjrust-proof sheetmetal. lSaidfla'shing strip is provided with `anv angularlyl deflected portion 2 3 which is,.in turn, rebent -to form a run r24'vl that overlies said portion 2,3 in a slightly'spaced v relation thereto. The free edge'portion 'ofrfsaidr run l2 4v is furnished with a lipl 25 directed up# wardly therefrom atran obtuse r angle*- rThe lengths lof the flashingpartsr23, 24 and 25 are such :as` to permit theedge of the Vlip-,2 5 kto beA seated within thehook I5 of thefvreglettas shown inY Fig. 2. and `tofpermit said lip tobe disengaged fromsaidhookby an outward swinging kofthef lower portion of the flashing strip, whereupon. the flashing strip-may be completely withdrawn from the ,reglet and wall groove.

Avlockingfrneans is provided to prevent `acci-v dental detachment of the iiashing from thereglet. Said locking means comprises a sheet metalclip 30havingone of its edgeportions furnished with a'rebentlip 3| and having*l through it ina spaced relation to said lipa triangular opening `372, which4 receives ao wedge-shaped key 33.A Thev lip 3| of n said clip v3ll-jforms a Vhook'which may readily be. hooked into the-.reglethook I5 in an ,underlying relation to the lip l25 of the flashingwhich also is shown` occupying said reglet hook I5. After this hasfbeen vdone and the key 25 wedged into place as shown it is impossible to swing ythe nashing' outwardly and disengage it from the reglet,V without first removing Vsaid key., It is to be understood that the portion of the inserted key above the reglet is in an abutting relation to the face of the wall, and the lower portion of vsaid key closely overlies the iiashing below said clip.

By preference and as shown said key 33 is made of a uniformly tapered strip of sheet Ymetal bent along its mid-.width `at a rightangle, its side apply suicient outward traction to withdraw the and stabilize the reglet sections as the building ofv the wall proceeds. Also said splicing pieces prevent leaking of the plastic concrete at'the reglet land-lower edges inwardly terminating in symjoints and they reinforce the reglet strip at these points. They are especially useful in the building of concrete structures Where the concrete is vibrated when being filled into the formsas'isV frequently done in the building of earthquakeproof Class A buildings.

In Figs. 1 and 3' is illustratedlone method of constructing a cementitious wall providedwith the invention. In Vthese views the Wall II is shown being built between -aV rear "form 40 and a front form 4 I, said frontformlhaving awooden shelf member 42 preferablytapered as shown, secured to the inner face thereof before the cement is poured, by means of spikes 50. Also, before the cement is poured, the `reglet sections I2a and-|21) are put in place oversaid shelf, as shown, tacks I2t or other fasteners being driven through the midwidth portion of the reglet and into the inner edge of said shelf to hold the reglet inplace during pouring of the cement. It is to be understood that the thickness of the shelf 42 at itsV Widest part is substantially vequal to the space between the reglet lips `I and I6.

The wide edge of the shelf strip 42 is shown abutted against the form member 4I in order better to stabilize the attached shelf and reglet carried thereby against the downward Vimpact of poured-in cement; also to facilitate the removal of theshelf after completion of the Wall. After the wall has had time to set the forms 40 and 4I will be withdrawn, as usual, and when this is v however, the moisture in the cement causes the shelf member to swell to such an extent that it is gripped very tightly within the mouth portion of the reglet it may remain therevs'rithi'nafterv the form 4I has been removed. If such be the case, sufficient time will be allowed to elapse to, permit the shelf member to shrink enough to release the grip of the reglet thereon, whereupon said shelf member may readily be `withdrawn Vfrom the reglet. In doing this pinchers may be applied to the projecting pointed ends of the spikes 5l! to shelf member from the reglet. Finally, the projecting pointed portions of the tacks I2t will beY cupying said groovevand retained therein by said shoulder portions, said reglet having symmetrically shaped keeper portions comprising van inwardly and downwardly directed hook portion at its upper edge and a like upwardly and inwardly directed hook portion at its lower edge, and a strip of flashing having an edge portion located within said reglet and positioned to be retained therein by said keeper portions.
