WALL DUCT. 1 w i Application filed May 27,
This invention relates to certain new and useful improvements in wall ducts, and the primaryobject thereof is to provide a duct of this type which is formed insections each having an open front'provided with aremovable cover, the sections havin g novel connections therebetween andibeing formed to be embedded in a Welland-with thecover flush with the finished face of the plaster, I0 together with means for holding pipes withinthe-duct, wherebyin-event of leakage of the pipes or' for any other purpose, access thereto is' desired, such-access may.be had without cutting andlremoving' the plaster.
A further object of the invention isto providea duct of this type whichwill 'act to confine any fluid'which may'leak from the pipes within the duct, thereby to prevent the leakage from-wetting and marring the plaster. ii I The 'inv'ention still further aims to provide novel means for holding the pipes.
In the drawings Fig. l is a front elevation of the invention;
Fig. 2 is a side elevation;
Fig. 3 is a section on line 33 of Fig. 1;
Fig. 4 is a section on line 4-4 of Fig. 2;
Fig. 5 is a section on line 55 of Fig. 2, and
Fig. 6 is a top plan view of one of the sections.
In proceeding in accordance with the present invention, each section of the duct is formed to have a back 1 and sides 2, the front being open. Each side 2 is flanged outwardly at 3 to lie parallel to the back and the free edges of the flanges are turned outwardly at right angles at 4 to form side guides for a cover 5. Nuts 6 are soldered or otherwise rigidly secured to the rear faces of the flanges 3 and are engaged by screws 7 which pass through the cover and through the flanges 3, so that the cover may be removed as desired or found necessary. Each section is provided with clips 9 or 10 by means of which same may be secured to the studding or built into a brick wall, the clips 9 being employed in the position shown in Fig. 1 in securing the section to studding, while the clips 10 are employed in the position of Fig. 1 in building the sections into a wall. The backs and sides at the ends of the sections are provided with extensions, the extensions at one end of each section be ing ofi'set outwardly to form tongues 8 while 1927. Serial No. 194,735.
the extensions at the opposite end. of the 1 section are bent upon-themselves 'as indicated-at 9 and then'b'ent-upwardly as indicated at 10 to form sockets to receiverthe tongues 8 of an adjacentsection. In this manner, itwill be seen that a simple islip omtf connection is ;provided enabling the sect1ons;.tobe easily and quickly connected and disconnected. 1 For the purpose of not-only holding, the
pipes in fixed position in the duct, but also for the purpose of strengthening -and.-bracin the latter, transverse plates 20-.are provided which: have downwardly flanged ;backs .21 and ends 22 which flanges abutfitheibacks and sides respectively ofqthe sectionsg The plates 20 are formed .withU-shaped seats 23 which extend through the .front sides of .the plates and which. are formed -,-of .--*various s1zes 'to receive different -,diam'etered pipes. Angle bars or strips24 have their; horizontal webs seated on the tops of theplates .20 and their. ends. abutting the. sides of {the-sec,- tions so as to brace the latter. Theangle strips are secured in position by bolts 25 and extend across the open outer ends of the seats 23 so as to close the latter, and by engaging the pipes hold the latter in position. The flanges of the plates 20 are held in position by means of bolts 26.
As shown in Fig. 6, the sections are embedded in the wall and with their flanges 4 flush with the face P of the plaster, the cover 5 being exposed.
From the foregoing, it will be apparent that in event of leakage, the cover plates may be removed without destroying the plaster. The invention is especially designed for large buildings wherein the walls are usually painted, in which instance the cover plates are also painted and can be easily and quickly removed as is apparent. The invention is susceptible of use with papered walls, but in the latter instance, the paper must be cut to enable access to the covers.
While I have shown nuts 6 in the drawing, still it will be obvious that these can be dispensed with if desired and the screws 7 directly threaded into the flanges 3.
What is claimed is:
1. In a wall duct, a box formed to be vertically embedded in a wall, having a back, and sides, the latter being flanged outward- 1y to be parallel to the back and having their free edges extended outwardly to lie at rightangles :to the flanges,,nuts fixedly secured to the rearfaces of the flanges, .a
cover seated on the flanges and engaged between the right angular free edges of the flanges, screws extending through the cover and flanges and threaded into the nnts,,a transverse plate secured in the box and hav ing U-shaped pipe seats thereimppening through the front edge of the plate, an angnlar strip seated on the plate and extending across-.theseatsto hold the pipes in the seats, and means' toseeure the strip in position.'. 2; In .-a wall duct, a box-formed to be Vertically-f embedded in a :wall, having a back, and sides, the latter being flanged outwardlyimbe parallelio the back and having-their free-edges extendedzoutwardly a to lie at right angles to theuflangesynuts fix- "edly secured to the rear faces'ofgthe flanges, a 'cover' seated-uon the flanges and engaged betweenthe rightangularzfree edges of the fiangegiserews extending through. the =eover. and fiangesand threaded into the :nuts,- and pipe holding means aw; thin the box.
" 3. In=- a -wall=d1ict,"a box formed to -be embeddedina wall and 'having an open front, af'eojer-foflthe front, means to removably' connect the cover to the box, a transverse plate secured in; the box and having U-sh'aped pipe seats" thereinopening through the Ifront edge of the-plate, a strip engagedjyvith the plate and-extending across the seats to hold the pipes in the latter, and means to secure the st-ripagainst movement.
bedded in a wall and hzn-ing an open front, aeover' for the" front, means to ren'iovably conneet the cover to the box, a transverse plate secured in the box and having U- shaped pipe seatsntherein opening through the front edge of the plate, said plate having a flanged rear and ends engaged with the rear and sides respectively of the box, an angular-strip having one side seated on the plate and extending across the seats to hold the pipes: therein and engaged at its ends with the sides of the box, said strip having its other side depending from the plate, and means to securethe strip to the .platev -.-5. In a wall duct, a sectional conduit, "each section having an open front, a back andsides each provided with a separate extension, theextensions of the back and sides of one section beingofi'setto form tongues and the extensions of the back and sides of the adjacent section being bent downwardly and then upwardly to form sockets to re ,ceive the tongues, 21 cover for the open front, means to secure the cover in position, and pipe holding means in the sections.
