socke as it be necessary to restrain it and dropping Such be easily accomplished intu ned end of the of the retainer illustrated at modified embodiment of the invention is illustrated at 7 to 10 and this embodiment provides for a cap Such a cap is used to protect an end of a section which a partial division of a room or the edge of an open and any other wall edge e it is not desirable or essary to mount a door in the case cf an external end of a wall section is often subjected to considerable a especially if the wall is located in a hallway system of a a substantial portion of the traffic is with hand the end of a wall is finished with a pair of corner beads if the wall is be or with a special section of tile if it is to be The present invention contemplates in lieu of these the single protective end C of substantially as that heretofore In cross this cap C has ance of a folded ncraber as parallel This ncraber is s vjith respect to the t dinai plane of wall appears a lino at In contrast h the corner the fold of O quires elongated surface at the center of the cap which lies to the plane of the wall whereon the is The width of this surface is sufficient to tho cap to correspond the thickness of finished wall as A arcuate 21a is at each side of this This se 21a has radius of one inch to provide for rounded corners at the end of the wall and to with side 20a at each side of the whoso surfaces lie flush with the surfaces of the opposite sides of the To this end cap in the s as tho corner a narro inturned offset 22a is at the outward of each 20a and a nounting 24a extends tho inner edge 25a of each offset 22a to lie in spaced Viith the adjacent face strip 20a and in spaced with the opposing 24a as In the cap C onto a stud wall such as illustrated at flanges the opposite faces of the stud of the wall to place tho side faces 20a outwardly flush with the finished wall In holding tho cap it is preferred that the counting flanges 24a be carried in sockets by retainer strips the as heretofore These strips are to he opposite faces of the stud Howeve in trast construction illustrated at the parallel flanges of the cap can easily slide out of the sockets 32 unless another for the cap is the shown at 7 includes a clip 41 within the end cap This as shown at is as a folded strip of sheet Its central base 42 carries a short upstanding leg 43 and each includes an inturncd offset 44 and an car 45 the inner of the offse This is tioned to fit within the end cap C with the ears 45 being adapted to and lie the opposite sides of the stud of the The flanges 24a of the cap then overlie these The offsets 44 are adapted to lie against the end cap offsets 22a to prevent the end cap noving outwardly the 3 The 43 lie between the opposing face strips 20a the base portion 4 connecting the opposing tions to reinforce tho other portions of the clip It is that a number of these clips 41 be fastened to a terminal stud as by nails 46 being driven 47 provided in the that this villi be the first step in mounting an end cap C onto the stud The clips are slipped into position in tho pulled tightly against the terminal stud and the retainers will be nailed in position over the flanges 24a of the end cap and at a tion which will provide for a suitable gap G between the ends of tho flange and the offset 22a of the end cap with the cap bearing against the offsets 44 of the clips a plaster stop will bo upon each wall to overlie the retainer strips to the 0 as heretofore The final step is to apply the lath and Figure 9 illustrates a partially pleted where end cap and retainer strips have been applied and tho section is ready for tho stop and lath and In that a retainer clip clip is as a body 52 is adapted to snugly the end of the stud and to be nailed with holes 53 on tho sides boing provided fore A 54 is folded outwardly this clip and it has a width sufficient to snuglyllic the opposing face strips 20a and with its inner corners 55 contacting the inner sides of the offsets 22a to prevent the end cap C being pulled away fron tho A further of the invention is illustrated at 11 where a corner bead B is secured to a nasonry wall of the typo which is to be finished by The corner bead is held by triangular clips proportioned in such a as to havo opposing corners 62 fit within the of tho face strips 20 and against the offsets Those triangular clips are placed between the joints of the naconry during erection of the They will havo suitable holes 63 their faco to then to be better gripped by the nortar when the or cinder blocks arc laid up as in the The corner guard nay bo placed with the erection of the while anchors 61 or 64 are slipped down and placed in retainer strips nay be or i it is possible to uso a plaster stop the strips by laying tho end of the stop directly over the flange as in the manner 12 illustrates a masonry clip 71 which be used in lieu of the clip This masonry clip is formed as a piece of flat sheet metal with a head portion having opposing corners will fit within the of the face strips 20 and against offsets 22 of a corner bead This clip is provided with a tongue portion 73 suitable holes 7 to it to be better gripped by the mortar between bricks or cinder blocks when the masonry wall is being It is quite apparent from the foregoing description that a similar retainer strip can bo provided for a Such a unit can be made as a simple clip formed similar to the unit illustrated at but in lieu of the body a flat plate shown in broken may bo formed which can lie between the courses of masonry with the ledge projecting therefrom to hold the s in I have now described invention in considerable it is obvious that others skilled in the art can and devise alternate and equivalent constructions which are nevertheless within the spirit and scope of my I desire that my protection bo not by the constructions illustrated and but only by the proper scope of the appended insufficientOCRQuality
