CORNICE BLOCK.

Application led March 8, 1927; Serial No. 173,708.

The block of the present invention is primarily designed for strengthening and holding. hollow terra cotta, tile, or artificial stone building blocks in proper position to form cornices, corbels, brackets and other projecting parts on a building.

An object of the invention is to provide a bloclrof this character which will greatly facilitate the formation of cornices and the like on buildings, and which will hold the cornice-forming blocks firmly in position when first assembled, and also after they have been set. j

A further object of the invention is to provide a block of this nature of simple, practical construction, which will be rugged, durable and efficient in use, and well suited to the requirements of econmical manufacture and convenient application.

With the above noted and other objects .in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out inthe claims. The invention maybe more fully4 understood from the following description in connection with the accompanying drawings, wherein- Y Fig. 1 is a fragmentary vertical sectional View through a building showing' a. cornice or bracket partially assembled and retained by the use of my improved block, the finishing blocks of the cornice being indicated in dotted lines.

Fig. 2 a vertical sectional detail ou the line 2--2 of Fig. 1.

`Fig. 3 is an enlarged top plan view of one of the blocks.

Fig. 4 is a longitudinal sectional view therethrough on the line 1f-i of Fig. 3.

Fig. 5 is an end View of the block.

It is to be understood at the outset that while I have shown the block of the present invention as applied to a cornice or bracket, it might be used with equal facility and with equal advantage inmany forms of building construction, and that the use of the word cornice in the specification and claims is to be construed to-cover vall analogous projecting structures.

In the drawings I have used the reference numeral to designate one ofthe outer walls of a building construction reinforced by the usual horizontal girders 11 and 12 embeddedv in the wall. A pair of angle bars 13 spaced apart and arranged back to back block 16 'is imbedded in a suitably prepared f recess 17 in the wall, and another cornice` block 18 projects still further fromthe wall face resting on the upper surface of the block 16. Additional blocks such as 19 are superimposed on .the block 1S. The particular number of blocks used in this stepped or corbelled formation which forms the cornice, is of course, subject to variation, but VI have simply shown the three blocks 16, 18 and 19 in place with additional finishing blocks indicated in dotted lines .at 20. The blocks 16, 18 and 19 are of hollow tile, terracotta, artificial stone, or equivalent material, and the. rod projects into the hollow body of the block 18. Angle bars 13 overlie and are in contact with the upper surface of the block 19. and the present invention is vprimarily concerned with the use of a block such as that shown in Flgs. 3vto 5 inclusive which assists in snugly anchoring the cornice blocks 16, 18 and 19 in position with'the y aid of a hanger or tie rod 21.

TheV block 22 of the present invention is shown as of general rectangular' shape havingalongitudinally extending groove 23 in its under face shaped to receive and seat upon the rod 15. The ends of the groove 23 are intersected by grooves 24 in the end faces of the block, either of which are adapted to Y embrace and receive Vthe hanger 21. The two grooves 24 are used simply so that the block is readily reversible and maybe quickly applied without need of the operator turning it 'about to seewhich end 'engages the hanger.

` Preferably all of the outside surfaces of the block 22 are ribbed or otherwise roughened as atl 25providing surfaces which may be readily anchored with mortar or other setting material. f'

The hanger 21 is in the nature'of a tiey bolt having an eye 25 at its lower end which encircles the rod 15, and having athreaded upper end 26 received between the spaced back to back angle bars and retained by a nut 27 bearing against a washer 28 whichf construction.

rests on the upper edges of the angle bars. Openings 29 in the block 19 align with an opening 8O in the block 18 to accommodate the hanger or tie bolt 21. lith the yblock 22 in proper position resting on top ot the rod 15, and embracing the tie bolt, tightening of the nut 2T Will tend to jam; the block 22 snugly against the inner surface. of the blocl; 18, thereby clamping the block 19 between the block 18 and the angle bars 13 and lending reniarlable strength and rigidity to the After the parts have been tightened, the mortar is applied in the usual manner, and the cornice linished by the addition oif Ythe blocks 20.

` Obviously, various changes and alterationsI might be made in the general jform and arrangements of parts described Without departing from the invention. Hence I do not Wish to limit myself to the details set vforth, but shall consider myself at libert?,7 'to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim:

1. A, block oi the class described of' generally rectangular formation having a longitudinall;7 extending groove in its under tace adapted to receive a supporting rod, and having a transverse groove in one ol its end faces intersecting the lirst mentioned groove and adapted to receive a hanger bolt, said second mentioned groove being venlarged to accommodate a supporting rod encircling eve on the hanger bolt.

2. A block 'of th-e class described of generally lrcctangular formation having a longitudinally extending groove in its under face adapted to receive a supporting rod, and having a transversegroove in one oi'. its end faces intersecting the first mentioned groove and adapted to receive a hanger bolt, said second mentioned groove being enlarged to in corbelled formation on the embedded a block, one of said blocls receiving the rod and another' of said blocks lying immediately subjacent the face ot' the bar, an adjustable tie bolt connecting the rod and bar and passed through the blocks, and a strength4- ening block fitting in the corner defmed .by the rod and tie bolt, bearingagainst the inner upper tace of the block which houses the rod `when the bolt is tightened.

il. ln a cornice construction, thecombination with abuilding` Wall and a cornice block suitably embedded therein, cfa rod projecting Vfrom the Wall above the bloei-1 and :i substantially rigid bar projecting from the wall above the rod, additional liollow blocks piled in ccrbellcd formation on the embedy ded block, one of said blocks receiving thil rod and bar and passed through the blocks. and a strengthening block 'fitting inthe cor ner delined by the rod and tie bolt, bearing against the inner upper face of the block which heures the rod when the bolt 'is tight ened, said bar being defined by the projectA ing ends ot a pair of spaced angle bars arranged baclr to back and having theirmrgosite ends embedded in the Wall, said tie bolt passing between them and including a threaded upper end receiving a tightening nut bearing against the edges ot `theangle bars.
