Specification of Letters Patent.

Patented Feb. 8, 1916 Application filed December 22, 1913. Serial No. 808,172

Be it known that I, GROVER C. ROYSE, a citizen of the United States, anda resident of Tacoma, in the county of Pierce and State of WVashington, have invented certain new and useful Improvements in Flue Structures, of which the following is a specification.

My invention relates to flue structures and more particularly to one embodying a flue lining and blocks so formed as to be readily incorporated into the structure and readily fitted around the flue lining in a novel manner to recive a binding material securing the blocks together and to the flue lining.

As my invention may assume diiferent forms, I show and describe a few specimens of the block which may be used, having different shapes and adapted for different pur poses, yet all containing the same general feature in so far as their fitting and jointure are concerned.

Reference is to be made to the accompanying drawing forming a part of this specification and in which like letters indicate like parts.

Figure 1 is a fragmentary elevation of the chimney in which a number of my improved flue blocks are incorporated. Fig. 2 is a plan view of the structure shown in Fig. 1,

the cap, however, being removed. Fig. 3

is a section on the line 33 of Fig. 2. Fig. 4 is a perspective view showing one form of my improved block. Fig. 5 is a view similar to Fig. 2 but showing the block as solid and devoid of air spaces. Fig. 6 is a detail showing partly in plan and partly in section, the form of block appearing in Fig. 5. Fig. 7 is a section showing my improved block made in a form different from that appearing in the other figures above mentioned. Fig. 8 is a section through a chimney in which my improved block is used in connection with spacing blocks.

I will first describe the form of block shown more particularly in Figs. 1,2,3,4and

v 8. The block is provided with a longitudinal portion 9 and with a portion 10 extending laterally from said longitudinal portion, these parts being integral with each other and together being of substantial L- shape. The longitudinal portion 9 is provided with a lug 14: extending laterally from it in a direction parallel with that in which the portion 10 extends. The block is provided with a partition 11 extending obliquely across the longitudinal portion 9. The block is provided with air spaces 12, 13 disposed upon opposite sides'of the partition 11. The blocks are arranged in layers or courses the extending portionlO of one block registering'with the end of the portion 9 of the next block as indicated in Fig. 2. Other courses of blocks 15, 16 similar to the block just described but thinner may be arranged in layers or courses and alternated with the blocks first described, asin dica-ted in Fig. 1. In doing this the blocks may be so arranged as to break joints and form a very effective bond as will be understood from Fig. 1.

The blocks of each course are disposed around a fine lining 17 having in this instance a square cross section and forming the inner lining. of the chimney the blocks being connected together and with the lining 17 by, aid of binding material 18 which may be cement or mortar and is provided with outwardly. extending portions 19 for effectively holding the blocks together.

As shown in Figs. 5 and 6 each block ner as the blocks 9, 10, 15, 16, with binding material 25 extending between the blocks as seen at 26.

I sometimes construct the block as indicated in Fig. 7. The block is shown at 21 and has substantially the form of a so-called hollow square as seen from above. The block is provided with lugs 25*, 26 integral with it and spaced apart so as to form air spaces 28, 29, 30. Encircled by the block 24 is a flue 27 having a square cross section and having walls against which the lugs 25 26 extend. The air spaces 28, 29, 30 are continuous from bottom to top of the chimney.

' In instances where the chimney is to have an oblong cross section as indicated in Fig. 8 I sometimes employ blocks 9 in connection with a flue 33, this flue having a length greater than its width according to the view shown in Fig. 8. The binding material employed is shown at 34: and is provided with portions 35, 36 extending outwardly for holding the blocks together. In connection with the blocks 9 I here employ spacing blocks 37 each provided with an air space 38, the spacing blocks thus compensating for the difi'erence between the length and width of the fine 33 and contributing toward making the oblong form for the gross section of the chimney as shown in The form of block appearing in Fig. 7 differs from that shown in Figs. 1 and 2 in that in Fig. 7 the block 24 takes the place of an entire course of blocks 9 shown in Figs. 1 and 2.

In all instances the blocks used, or some of them have lugs extending inwardly to- ;ivard or against the outer surface of the Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

A block comprising a body portion extending longitudinally and an extending portion integral with said longitudinal portion and extending laterally therefrom, said block being further provided with a lug integral with it and extending from it in the same direction as said extending portion, said block being further provided with compartments and with a partition extending obliquely across said longitudinal portion and located between said compartments.
