DOOR FRAME AND BRACKET ASSEMBLIES Filed Jan. 29, 1962 3 Sheets-Sheet 3 INVENTORS PAUL M. .DoMs/c I DIELMAN BY HAROLD MJW United States Patent 3,177,532 DOOR FRAME AND BRACKET ASSEMBLIES Paul M. Domsic, Cleveland, and Harold J. Dielman, Lyndhurst, Ohio, assignors to The Sanymetal Products Company, Inc., Cleveland, Ohio, a corporation of Ohio Filed Jan. 29, 1962, Ser. No. 169,265 5 Claims. (Cl. 20-16) This invention relates to door frame and bracket assemblies, and more particularly to door supporting hinge brackets and a door stop bracket having associated clamping means by which the brackets can be externally applied and rigidly mounted on the jamb edges of tubular doorframe forming posts or pilasters, either before or after erection of the pilasters in the field.

Cubicle compartments, as generally used to divide interior building space into separate rooms such as hospital and toilet cubicles, are generally composed of two or more spaced posts or pilasters between which a door is swingably mounted, and having spaced dividing partitions extending between a vertical wall of the building and the respective pilasters. The dividing partitions and door bodies are usually limited in thickness to approximately one inch to conserve space, and the doorframe defining pilasters are also preferably limited to a thickness of not substantially more and preferably less than one and onehalf inches. To insure maximum sanitation, and to facilitate cleaning of the Wall surfaces, the door supporting hinge brackets as well as door stop brackets are preferably confined to the jamb edges of the doorframe defining pilasters, and so that no part of the hinge brackets or door stop brackets overlap the side wall forming faces of the pilasters.

The relatively thin doorframe forming pilasters have heretofore been assembled from a pair of side wall facing pans which are separately shaped and notched and then assembled together to provide a pilaster body whose vertical edges are covered by semi-tubular edging strips which are telescoped over and interlock with outwardly flared lip portions extending from the vertical edges of the pilaster body. Hinge brackets and/ or a door stop bracket can then be locked in mounted position on the jamb edges of the pilaster body by providing a tongue which projects from one or both ends of the hinge bracket or door stop bracket, and which interlocks with the semitubular edging strip which is telescoped thereover, as shown in the Benham Patent 2,876,874.

However, certain cost savings in pilaster manufacture may be effected by the continuous rolling of a strip of sheet metal or the like into tubular form and of the desired cross-sectional shape, and then transversely cutting the rolled tube into desired lengths to thereby provide preformed tubular pilasters whose exterior outline and appearance closely resemble the pilasters heretofore made from a pair of facing pans whose jamb edges are covered by semi-tubular edging strips.

This invention is particularly directed to the provision of hinge bracket assemblies and a door stop bracket assembly which can be externally mounted and rigidly clamped to the relatively narrow jamb edges of preformed tubular pilasters.

The improved hinge bracket and door stop bracket assemblies made in accordance with this invention, each comprise a bracket part which is cast or molded from a ice suitable metal or plastic and which presents a saddle sec tion having a utility arm, such as a hinge pintle supporting arm or a door striker arm, extending forwardly from the front face of the saddle section. The rear face of the saddle section is contoured in conformity with the jamb edge of the preformed pilaster to seat snugly thereagainst. A bracket supporting boss, preferably of circular cross-section, extends from the rear face of the saddle section and is designed for snug insertion into a correspondingly shaped mounting hole formed in the jamb edge of the preformed pilaster. The rim of the mounting hole thus provides seating support for the boss projecting therethrough and which transfers the weight strains imposed upon the utility arm of the bracket directly to the preformed pilaster structure.

Clamping means are provided for rigidly securing the bracket part in mounted position on the jamb edge of the preformed pilaster. The securing means preferably comprises a screw member having a neck section and a manipulating head extending through a countersunk bore formed in the saddle section and supporting boss of the bracket part, and whose threaded shank section extends rearwardly of the supporting boss. A sturdy toggle block or clamp member has a threaded bore in the approximate medial area thereof which receives the threaded shank of the screw member.

The screw supported clamp member is so shaped that it may be inserted through the mounting hole in the jamb edge of the preformed pilaster, and to thereby position the clamp member within the preformed tubular pilaster, when the bracket supporting boss has been fully inserted into the mounting hole in the jamb edge thereof. The total transverse length of the clamp member is slightly greater than the transverse distance between the inner surfaces of the side wall facing sections of the preformed pilaster so that, when the exposed head portion of the screw member is externally rotated, the end extremities of the clamp member will engage the inner surfaces of the side wall sections of the pilaster and thereby prevent movement of the clamp member as the abutment faces thereof are drawn into abutting engagement against inner surface portions of the jamb edge of the pilaster, when the screw member is tightened. As thus assembled, the rear face of the saddle section of the bracket part is drawn into rigidly seated engagement against the outer surface of the jamb edge of the pilaster, and the jamb edge of the pilaster is thus tightly clamped between the rear face of the bracket saddle section and the clamp member positioned within the tubular pilaster.

The hinge pintle supporting arm of the hinge bracket is bored to receive a hinge pint-1e which is designed to extend into the door body, and on which the door body is swingably mounted. The pintle receiving bore may be made in cylindrical form to provide a journal in which the hinge pintle may rotate, or the bore may be made in tapered form so that the correspondingly tapered end sec tion of the hinge pintle may be rigidly secured thereto as by a lock nut.

Where the jamb edge of the pilaster is to extend both above and below the hinging arm of the bracket, the bracket part may be provided with upper and lower saddle sections extending above and below the hinging arm, so that the rear surfaces of both upper and lower saddle sections brace against the jamb edge of the pilaster. In

such case, the bracket supporting boss preferably projects from the rear face of the upper saddle section only.

Where the hinge bracket assembly 'is to be attached to the upper end of va floor supported pilaster, or to the lower end of a ceiling suspended pilaster, the bracket part preferably presents an upper saddle section only, with i the hinging arm projecting forwardly from the lower end of the saddle section, and with the bracket supporting stop designedto limit the swinging movement of the.door,:

the bracket part presents a striker arm against which the swinging door may abut and which extends. forwardly from one side of the bracket saddle-section. The door stop saddle section presents a rear seating surface in contour conformity with the jamb edge of the preformed- Q vention itself, and the manner: in'which it may be made and used, may be better understood by referring .to the pilaster to which it isto be attached, and'thebracket sup-' porting boss'preferably extends from the rear, surface of} the saddle section at the approximate medial area thereof, and is shaped for snug insertion into the conformed mounting hole formed in the jambv edge of the pilaster field, and provides a sanitary cubicle construction whose wall surfaces may be easily cleaned and maintained in sanitary condition. The clamping means and bracket supporting bosses of these bracket assemblies operate to rigidly and immovably secure the bracket parts to the jamb, edge of the pilaster against possible loosening through many yearstof use and abuse; The screw members mayebef made tamper proof by shaping the screw headsthereof so that theykcan be turned in a tightening .direc'tion only, or if desired, the screw heads may be covered or, concealed, after application to "the pilaster,

by means of a fillet or coating compound, so that they are not visible or discernible. i

Other objects and advantages of this invention will become apparent as the disclosure proceeds.

Although, the characteristic features of this invention will .be particularlypointed out in the claims, the infollowing description taken in connection with'the accompanying drawings forming a part hereof in'which:

The doorstop bracket part is rigidly clamped to the t jamb, edge of the pilaster by clamping means as above V described, and which comprises a clamp block'or' member having a threaded herein the medial area thereof which receives the threaded shank section of' a screw member, and whose neck and head portions extend through and are rotatably supported within a countersunk bore extending through the saddle section and supporting boss of the bracket part'., A drawbolt receiving pocket, designed'to receive the projecting'e'nd of a drawbolt slidably supported within the door body and pro jecting through the swinging edge thereof, may be formed in the saddle, section and bracket supporting boss of'the bracket part. In this case, the bottom wall of the drawbolt pocket forms a part of the bracket supporting'boss,

and this bottom wall is provided witha counter-sunk bore which receives the neck portion and head portion of the screw member, 7 a

The door stop bracket assembly maybe made for reversible application to the jamb edge of the preformed pilaster, to accommodate either left or rightthand swing-V ing doors, by centering the bracket'mounting hole in the jamb edge of the preformed pilaster 'equidistantly' be-, tween the side wall, sectionsfoffthe pilaster, and by centering the drawboltreceiving pocket in the bracket part centrally'of the supporting boss thereof. iAs' thus made, the 7 door stop bracketassembly may be mounted onthepreformed pilaster in the field to, thereby place its striker arm' on either side of the erected pilaster to thereby accommodate a doorwhich is to swing either inwardly or outwardly.

Bracket assemblies may be made in accordance with this invention to provide door supporting hinge brackets A or A or door stop bracket B, each bracket having a toggle clamp assembly 15 associated therewith for rigidly securing the bracket assembly to a wall member or the jamb edge of a doorframe defining post or pilaster 1. The bracket assemblies of this invention are particularly designed for exterior application to the jamb edge of relatively thin doorframe defining pilasters of tubular form and generally rectangular cross-section and whose thickness is in the order of approximately two inches or less.

Tubular pilasters may be economically formed from a strip of sheet metal or the like which is rolled into tubular form to present a pair of spaced wall facing sections 22 and opposite jamb edge sections each defined by a pair of shoulder forming corner portions 3-3 extending inwardly from the side wall facing sections 2--2 and joined by an outbowed intermediate jamb edge portion 4, as shown in FIGS. 1, 2, 3, 4, 6, 10 and 13. The free longitudinal edges of the rolled sheet are crimped together to provide an internal interlocking seam 5 positioned adjacent to one of the shoulder portions 3 as shown in FIG. 4. The continuously rolled tube as thus formed may be transversely cut to provide rolled tube pilasters of proper length. The tubular pilaster may be made of any desired width, ranging from three inches to eight inches or more, and provides a sturdy doorframe structure upon which the door supporting hinge bracket assemblies and/ or the door stop assembly may be externally mounted.

Suitable mounting means are provided for rigidly securing one end of each doorframe forming pilaster to the floor wall as shown in FIG. 1 or the ceiling wall as shown in FIG. 2, and for leveling the erected pilasters to accommodate the floor wall or ceiling wall irregularities. By way of exemplification, the pilaster mounting means 6 as shown in FIG. 1, may comprise a U-shaped bracket 6a secured to the floor wall as by lag screws 6b. A companion U-shaped bracket 60 is rigidly secured to the inner surfaces of the wall facing sections 2-2 of the tubular pilaster 1, and its vertical legs may be adjustably secured to the vertical legs of the wall attached bracket 6a as by adjustable nuts and bolts 6d. A threaded stud 6e, extending between and connecting the wall attached bracket 6a and pilaster attached bracket 6c, may be manually adjusted to raise or lower the pilaster to precise elevation. The floor mounting means 6 is desirably concealed within a tubular shoe 7 which slidably telescopes over the pilaster and may be brought into abutting rela tion to the floor or ceiling wall to conceal the pilaster mounting means therein.

Where the pilaster is to be suspended from the ceiling wall as shown in FIG. 2, a modified pilaster mounting means as shown in FIGS. 2, 24 and 25 is preferably used. This modified pilaster mounting means essentially comprises a U-shaped saddle bracket 37 presenting a web portion 37 and a pair of spaced leg portions 37" designed to snugly telescope into the terminal end 1' of the pilaster and secured as by spot welds 37a to the inside surfaces of the side wall facing section 22 thereof. The paired leg portions 37" have a notch cut-out 37b at each end thereof, and which define end extensions 37c spaced from the terminal end 1' of the pilaster 1. A U-shaped platform member 38 is telescoped over each end extension 370 and presents a platform portion 38', inner and outer end flange portions 38" which seat against the inside surface of the saddle bracket web portion 37, and a pair of side flange portions 38" which snugly telescope over the sides of the lower end extension 370. A lag bolt 39 extends through aligned holes or slots in the web portion 37' of the saddle bracket 37 and the platform portion 38' of each platform member 38. A clamp plate 40, having a hole therein through which the lag bolt 39 extends, is clamped between the web portion 37' of the saddle bracket 37 and a leveling nut 39 threaded on the lag bolt.

The ceiling suspended pilaster is secured to the ceiling wall by first rigidly securing at least one lag bolt, and preferably two lag bolts 39, to the ceiling wall, applying the leveling nut 39 and clamp plate 40 to the threaded shank of each lag bolt, then telescoping the wall secured lag bolt 35? through the aligned holes in the web portion 37 of each end extension 37c of the saddle bracket 37 and through the aligned hole in the platform portion 38' of the platform member 38, and then applying a clamp nut 39 to the end extension of the lag bolt 39. The clamp nut 39 and leveling nut 39" are then adjusted to level the suspended pilaster in precise vertically extended position. The same pilaster mounting means 36 may also be used to secure the lower end of the pilaster to the building floor, and to facilitate the assembly of the saddle bracket 37 to the terminal end of the pilaster 1, the U-shaped saddle bracket may be made in two parts by forming the web portion 37 thereof in two similar half sections. The pilaster mounting means 36 may then be concealed from exterior view by means of a tubular shoe 7 which telescopes over the pilaster 1 and the pilaster mounting means 36 and seats against the ceiling or floor wall of the building.

A pair of tubular pilasters 1 are secured to the floor or ceiling wall of the building in aligned and appropriately spaced relation to receive a door D therebetween, as shown in FIGS. 1, 2 and 3. The relatively thin door body is swingably supported from one of the pilasters 1 by a pair of upper and lower hinge bracket assemblies A-A as shown in FIGS. 1 and 2, and the swinging move- 7 ment of the door may be limited b V 7 stop assembly B mounted on the adjacent jamb edge of y a reversible door a of: the clamp screw 17 V have .ing hole 4' of the pilaster, the reaarwardly. projecting boss the companion tubular pilaster 1.

lower end of each pilaster maybe closed by asuitable closure cap 9 which may be contoured in conformity with the vertical jamb edges of the 'pilaster; The tubular pilasters maybe filled with sound deadening insulation edges 13 .of'the hinge bracket snugly seated against the adjacent shoulder portions 3-3 of the pilaster. A screwdriver or other manipulatingtool can then be applied to the head portion 17' of the clamp screw 17 to thereby draw they'clamping faces 16" of the clamp block 16 tightly against the inner surfaces of the shoulder portions 33 of the. pilaster structure. By reason of the shape and configuration of the clamp block 16, one pair of opposite tapered end faces 16' of the clamp block 16 will injected into one end thereof after manufacture thereof. It will also be appreciated that the floor supported pilastejrs may also be made to terminate substantially at. the 7 same level as the top edge of the door, .and the upper ends thereof capped by suitable closure caps 9. v

Thedoor supporting hinge bracket A, as shown more particularly in FIGS. 4, 5. 7, 8, 9," and 10 may be integrally cast froma suitable metal or molded from a plastic compound, to present an upper saddle section10 and a' lower saddle section 11 from which a hinge. arm; 12

late-rally extends. The hinge arm 12 presents a pintle receiving bore 12' to which the door. hinge pintle p is either fixedly secured or is rotatably mounted. The outer faceslt) and 11 of the upper and

rear edgeof the door body D may be'provided with a suitable corner .cut-out in which 'a reinforcing corner bracket is fitted and which provides a journal for the hinge pintle p which extends from the hinge arm 12 of the upper hinge bracket'A: 'A similar hinge bracket assembly A may be' used to provide the upper hinge bracket for the ceiling suspended pila ster 1 as shown in 'FIG. 2, and whose hinging arm 12 may extend into a U-shaped reinforcing bracket fitted within a pnotch cutout formed in the rear edge of the door body D and which receives'thehinge pintle p journaled in the bore 12' of thehinging arm 12 of the upper hinge bracket A.

* '.The lower end of the door bodyD is preferablyswingably supported by a hingebracket assembly A of some- 7 what modified fornras shown in FIGS. 1,2, 11 and 12.

-A bracket supporting boss 14 extends rearwardly from:

the concave rear face 10" of the upper saddle section 10 of the bracket A, and is designed for snug insertion The hinge bracket A presents an upper saddle section 10 i only, and from whichthe'door supporting hinging arm 12 extends. The hinging arm' 12 has a pintle receiving bore 12 to which the lower door hinging pintle p. is secured,

into a mounting hole 4 formed in thearcuatejamb edge portion 4. of the pilaster 1. i The boss receiving hole 4' may be advantageously made in circ'ularforrn so that it can be conveniently. formed by arotary drill., In such case, the rearwardly projecting boss 14 isv made corr'espondingly circular in cross-section to snugly fitv within the circular hole 4', and so that .the peripheral rim'14' v of the bossaswell as the hinge bracket itself is sup-" ported by the circular .rim14" of :the drilled hole 4,,as'

shown in FIGS. 4 and 5.

The hinge bracket A- is rigidly" secured in mounted position on thejamb edge. of the pilaster by the provision of. a clamp or toggle assemblyIS formed as'shown in.

FIGS. 4, 5, 7 and 1Q- .The clamp assembly comprises a clamp memberor block 16 which has an axially threaded hole which receives the threadedshank 17' ef ascrew 'mernber 17 whose neck and head portion 17" seats within a counter sunk hole extending through the upper, saddle section 10 and the. rearwardly extending supporting boss 14.

The clamp block 16 is so shaped and formed that, when the clamp block and screw member, 17 have been assembled as a unit to the upper saddle section 10 ofthe hinge I bracket A as shown in FIG.7, thecliamp block 16, can

be inserted into the mounting hole 4" in the jamb, edge a hinge bracket.

After the clamp block 16 'and'the shankjsection 17' 12. The hinge bracket assembly A as shown in FIGS. 11 and 12 is applied to. the: jamb edge of the tubular pilasterzin the same manner as the bracket assembly A previously described; namely, the clamp block 16 and associated clamp screw 17 of the hinge bracket assembly A are first inserted. into the mounting hole '4' in the jamb edge of the pilaster, the boss 14 then snugly titted within The saddle.

A bracket supporting boss 14 extends the mounting hole, and the head portion 17" of the clamp screw 17 then manipulated to draw the clamping faces 16" of the clamp block 16 in tightly seated position against the inner surfaces of the shoulder portions 3-3 of the pilaster.

When the hinge bracket assemblies AA' as above described are mounted on the jamb edge of the pilaster in the manner above described, a sturdy swinging support for the door is provided which will withstand many years of use and abuse. The door weight, as well as additional weights which may be app-lied to the swinging door, is transmitted through the hinging arm 12 of the hinge bracket assembly and thence to the boss 14 extending rearwardly from the saddle section 1%, and which is in turn supported by the rim 4" of the mounting hole 4 formed in the jamb edge of the pilaster. The clamp block 16 and associated screw 17 not only rigidly maintain the rearwardly projecting boss 14 in supported position within the pilaster mounting hole 4, but also serves to clamp the side seating faces 13 and arcuate rear face of the saddle section 10 of the hinge bracket tightly against the shoulder portions 33 and intermediate portion 4 of the pilaster structure. When the door D is mounted on the hinge pintles p as supported by the hinging arms 12 of these hinge brackets, the adjacent edge of the door overlaps the head portions 17" of the clamp screws 17 so that the screw heads cannot be manipulated or tampered with, without first removing the door. However, it will be appreciated that the counter-sunk screw heads 17" may be formed to permit turning of the clamp screw 17 in a tighening direction only, or the exposed faces of the counter-sunk screw heads may be concealed by a suitable filler compound.

The hinge bracket assemblies A-A' may be applied to the pilaster at the factory, or they may be applied either before or after the pilaster has been erected in the field in cases where floor or ceiling wall irregularities or other building conditions so require. For example, in order to assure accurate door alignment, the bracket mounting holes 4' may be drilled into the arcuate portions 4 of the pilaster at the proper locations in the field, and the hinge bracket assemblies then attached thereto.

The door stop bracket assembly B as shown in FIGS. 1, 2, 3, 13, 14, and 16, comprises a bracket part which presents a saddle section 20 having a striker arm 21 of attractive contour which extends laterally from one side thereof. The inner face of the striker arm 21 is preferably provided with a bumper or cushioning pad 21 formed of resilient material which is locked or otherwise bonded to the inner face thereof and against which a side face of the swinging door body is designed to abut. The saddle section 20, as shown more particularly in FIG. 15, presents a contoured outer face 20' which smoothly merges into the inner face of the striker arm 21, and presents an inner face 20" in shape conformity with the outer surface of the outbowed intermediate portion 4 of the pilaster and against which it is designed to snugly abut. The saddle section also presents a pair of spaced side seating faces 22 and 23 designed to snugly seat against the exterior surfaces of the corner forming shoulder portions 3--3 of the pilaster.

The'striker arm 21 of the door stop bracket part is laterally offset to a suflicient extent so that the door contacting face of its cushioning pad 21' will permit the door when closed to move into medial alignment with the pilaster 1 to which the door stop assembly is attached, proper account being taken of the relative thicknesses of the door body and pilaster body. A bracket mounting boss 24, preferably of circular cross-section as shown in FIGS. 15 and 16, is designed for insertion into a corresponding circular hole 4' centrally bored into the arcuate intermediate portion 4 of the pilaster. The peripheral rim of the circular boss 24 is supported by the perimetrical rim 4" of the mounting hole 4, and the bracket part if? is locked to the jamb edge of the pilaster by means of a clamping assembly 15 which may be similar to the clamping assembly used to secure the hinge brackets A and A to the jamb edge of the companion pilaster as heretofore described.

Where the door is equipped with a latch or lock bolt b, a latch bolt receiving pocket 25 of preferably elongated shape may be cast or molded in the saddle section 20 and mounting boss 24 of the door stop bracket part. The closed end latch bolt receiving pocket 25 is defined by a bottom wall 26 which forms a part of the mounting boss 24. The bottom wall 26 has a conical bore which receives and rotatably supports the neck and head portion 17" of the screw member 17 of the clamping assembly. The threaded shank section 17' of the screw member 17 is designed to project beyond the rear face of the mounting boss 24- and extends through a threaded hole in a clamp block or member 16 at approximately the medial area thereof, as shown in FIG. 15. The opposite ends of the clamp block 16 present tapered end faces 16' which define terminal crowns 16" which are spaced slightly greater than the distance between the inner surfaces of the side wall sections 22 of the pilaster to which it is to be attached.

.The door stop bracket assembly B is applied to the jamb edge of the pilaster structure by first inserting the clamp block 16 and the threaded shank section 17 of the screw member 17 to which it is attached, through the mounting hole 4 in the manner shown in FIG. 10. The mounting boss 24 of the door stop bracket is then snugly inserted into the mounting hole 4' of the pilaster, and the screw head 17" initially rotated to swing the abutment crowns 16" of the clamp block 16 into abutting contact with the inside surfaces of the side wall sections 2-2 of the pilaster. Upon further rotative movement of the head portion 17" of the screw member 17, the abutment faces 16' of the clamp block 16 are drawn into seating contact with the inside surfaces of the shoulder portions 3-3 of the pilaster. When the screw member is fully tightened, the shoulder portions 3-3 of the pilaster are rigidly clamped between the clamping block 16 and the spaced side faces 22 and 23 of the bracket part, and the door stop bracket part is thereby rigidly secured to the jamb edge of the pilaster.

The door stop assembly B may be reversibly applied and mounted on the jamb edge of the pilaster to accommodate either right or left handed swinging doors, by centering the mounting hole 4 in the medial center of the pilaster body, and by also centering the latch bolt receiving pocket 25 in the axial center of the bracket supporting mounting boss 24. The manipulating head 17" of the screw member is positioned at the bottom of the latch receiving pocket 25 and is substantially invisible. To prevent tampering, the exposed face of the screw head may be concealed by a fillet plate snugly driven into the latch bolt receiving hole 25, or the screw head may be concealed by a filler compound.

The hinge bracket assemblies A and A and the door stop bracket assembly B as above described may also be applied to the jamb edge of a fabricated pilaster 30. As shown in FIGS. 17 and 18 the fabricated pilaster 30 as heretofore known and used, is formed from a pair of similar facing pans each of which presents a side wall facing section 31 and an inturned flange portion 32 extending along the exposed vertical jamb edges and exposed horizontal edge of the fabricated pilaster. Each of the inturned flange portions 3232 presents an outwardly flared lip portion 33 over which a semi-tubular edging strip 34 is telescopically applied. The paired facing pans are secured together in rigid assembly as by spot welds 33" externally applied to the crotch area between the paired outwardly flared lip porions 33-33.

In the jamb area where the hinge bracket assembly or door stop assembly is to be applied, the outwardly flared lip portions 3333 may be cut off so that their terminal it ends 33 expose the inturned flange portions therebetween, and so that the mounting hole 4 can conveniently be drilled through the flange portions 32-32: 4 without also drilling the mounting'hole through-the flared lip portions 33-33. Corner forming shoulder parts 3-3 are thus presented on each 'side'of the'-mounting hole 4' as drilled through the inturned flange portions 32-32 of" the pilaster body as shown in FIG; 18 The bracket mounting hole 4' maybe drilled through the arcuate facing portion 34' and inturned flangev portions'v34" of the semitherewith maybe formed and assembled to the-brackets in a low -costoperation. These bracket assemblies may also be applied to the jamb edge of :1; rolled pilaster or a fabri-' cated pilaster either at the factory or in the field in mini mum time and with minimum labor.

Themounting hole4 formedin the jamb edge of the preformed pilaster can be quickly and conveniently made in circular form by a rotary drill of appropriate diameter,

tubular edging strip 34, and also through the'inturned flange portions 32-32 of the pilaster facing pans, after telescopic application-of the semi-tubular edging strip 34 to the jamb edge of the pilaster, Thus the bracket mountl ing hole 4' may be drilledinto the jam edge of the fabricated pilaster 30 after the pilaster has been fully assem-- bled, as indicated in FIG. 17. Where certain types of r drills are used, the bracket mounting hole may be drilled into the jam edge of the fully assembled pilaster without precutting of the outwardly flared lip portions 33-33 thereof, and so that the mounting hole 4' extends through i p the outwardly flared lip portions 33-33 and inturned flange portions 32-32 of the pilaster bodyfas well as through the arcuate facing portion 34 and inturned 7 flange portions 34 of the semi-tubular edging strip 34.1

The hinge'bracket assembly A 'is applied to the jamb edge, of the fabricated pilaster 30 as shown in FIGS. 19

and-21 by first insertingithe'clamp blocklfi of its'clamp assembly through the mounting'hole 4' formed in the jamb edge thereof as above described, and then insert-' ing the bracket supporting bo ss 14 into the mounting hole 4. Upon'tightening of' the 'screwmember 17, the clamping faces 16" of the clampblock 16 are .drawn into seating abutment against the inner surfaces of .the shoulder forming parts 3-3 of the inturned flange. portions32-3Z which have not been cut away by the'mounting hole 4" formed therein. As thus applied, the inner arcuate faces 10"-11

ofthe saddle sections

10 and 11 will snugly seat against the arcuate facing portion 34 of the semitubular edging strip 34,and with the side edges 13-13
