1 Be it knownthat I, ROBERT L. GAMnwnLL,

-' a citizen of'the United States of America,

residing at Birmingham, in the county of Jefierson and State of Alabama; ha've invented certain new and useful Improvements in Hollow-Tile Silos,- of which. the following is a specification. i

The present invention relates to improvementsin' hollow tile' silos,- and is designed to provide a reinforced structure adapted to'support a tank if desired.

- lVhile 'I shall hereinafter refer, in my specification, to a silo construction, it will be understood that the invention is equally applicablefor use in constructing straight masonry walls for other purposes. The primary object of the invention is to reinforce the tile and concrete construction of the-wall so that it will be sufficiently vention consists essentially. in the combinahereinafter described and claimed. In'the accompanying drawings tionw-ith the tile or hollow blocks and their concrete cores of specially constructed and.

arranged reinforcing rods or .bars as will be I have illustrated one complete example of the physical embodiment of my invention con-' structed according to the best mode I have so far'devised for the practical application of the principles of my invention, the drawings showing a silo structure, but it will be understood that. other structures are contemplated within the scope of my invention.

Fig. 8 is an enlarged sectional view on line.33 of Fig. 1. Fig. 4 is a sectional detail view on line fir-4: of Fig.

In the preferred embodiment of myiri'n vention as shown in the drawings thetsil wall is made up of courses of tiles orxhol low blocks as 1, laid course upon course'gant the. blocks are molded with inner and folltei tf curved faces to provide a circular; wallwhen the. rows are completed. Each r-block' is formed with an outer vertical web 2, a par-.3...

tition or intermediate web 3 and itsinnerh weh, while the end webs 5, 5, complete the outline of the block.

curved to form a semi-cylindricalspace 10 and the curved intermediatepartitions l1 which extend transversely between the concrete as indicated in the drawings"the cores of concrete extending from the bot-fl tom to the top of the structure and fil'liilg wall are reinforced by .a' continuous'netf work of metal bars or rods WI h extend's 1 around the silo andare' util; ed hold-the blocks in vertical ali-nementfl om the bottom to the 'top of the silo.

The reinforcing net work comprises a series of horizontally extending bars as 13 each of which extends from one door jamb provided with grooves or notches in their;

These notches are located at the top of the blocks just to one side of their center lines. and extend through the end walls, the longitudinal intermediate walls and the curved intermediate partitions 11, so that the-curved bars 13 may be laid on the top of each course of hollow blocks, resting in the grooves or notches. horizontal bars, in pairs, are a multiplicit of vertically extending rods 16 formed wit 1 end hooks 17 opening in opposite directions as seen in Fig. 10. These hooks are adapted to engage over the horizontal bars, and the rods pass through the voids or spaces extending vertically through the blocks, a

which it will of course be understood are open at top andbottom. In Figs. 7 and 10 it will be seen that the upper hook 17 engages over the. upper horizontal bar and it These webs provide' the four spacesfi, 7, 8, 9, the end Walls. are

75 two side walls 2, 4t formcylindrical-spacey; 12. In use all these spaces are filledlwith'."

so the crevices between the blocks- 'of'each course and row. These .blocks forming" the 9O 14 to the other jamb 14- and the blocks 1 are If Connecting these doorway, but connecting The arrangement of the hooks and that the lower hook engages under the lower bai. rods on the bars is well shown in Fig. 7 a where it will be seen that an effective net work of reinforced metal is provided which permeates the silo wall from top to bottom and throughout its circular wall.

In Fig. 5 a hook 13. is shown at the end the horizontal ring or bar 13 which hook engages about the rod 16 in the half jamb block 18, and the other end of the bar (not shown) is hooked to a similar rod 16 across the doorway. The bars 13 stop short of the bars 19, (Figs. 1

and 2) extend across the doorway from jamb to jamb in line withthe bars 13 and these connecting bars have hooks 19 engaged about the vertical rods 16. These connecting bars, in addition to strengthening and bracing the door way, perform the function of ladder rungs or rounds so that ascent of the silo may be accomplished at the doorway extending from bottom to top of the silo.

The doorway is closed by door sections 20 which are supported on the projections 21 of the sills '22 and the sills are blocks spaced way from jamb to apart vertically, extending across the doorj amb with a horizontally extending bar 19" therethrough for reinlforcement. The doors are preferably lined with asbestos paper to make the joints air tight, and at the ends have rounded edges 23 which fit neatly into the rounded or grooved corners 24 of the'jambs at the inner side of the doorway. I

When the tank is supported at the top of the silo as indicated at 25 in Fig. 8 the wooden joist 26 beneath the tank bottdm 2'7 is secured to the silo wall by means of the angle bracket 28 which is nailed to the ,joist and has an anchoring rod 29 fixed therein and passed through the wood plate 30 into and is embedded in the concrete core of the block 1.. W hen a sloping or peaked roof is used instead of the tank at the top of the silo, the rafter 81 is supported by the bracket and anchoring rod as shown in Fig. 8.

It will be understood that all the circular voids or spaces in' the blocks are filled with concrete, and these concrete'cores together with the interior net work of reinforcing steel bars and rods, render the structure exception-ally strong and capable of bearing great weight. It should be noted that the websof the blocks in courses, have a perfect bearing upon tlie'webs below, as the horizontal bars are embedded below the top surface of the blocks.

I claim A wall composed of hollow blocks laid in courses and formed with longitudinal grooves having a horizontally extending 'bar in the grooves of each course below the top thereof, said blocks each fashioned with curved end walls tornnng vertical spaces between ad oining blocks and an lntermediate space in each block, vertically ar-.

ranged rods passing through said spaces and hooked ends on said rods engaging said horizontal bars in pairs, and concrete cores incasing said rods and embedded in the spaces of the blocks.

In testimony whereof I afiix my signature.

ROBERT L. GAMEWELL.
