making machines provided with suitable dies, whereby the blocks may be formed complete ready for burning; and further to provide a building block of this kind that may be readily and easily set in position at the sides of an opening in a building, and when so set the building block itself will form a mold to receive cement or the like which cement may enter and fill the building block and also the adjacent portions of ordinary hollow tile blocks used for making walls to thereby form a completed structure in which nothing is visible from the exterior except the vitrified tile, and at the same time the walls and door frames will be firmly and rigidly united and held in place and reinforced by the concrete or other material within the hollow tile.

A further object is to provide a frame of this kind that may be readily, quickly and easily shaped by the operator who is con structing the building so that the frame tile may be adapted for use in connection with hollow tile walls of different thicknesses.

A further object is to provide a building block of this class that may be readily and easily shaped to receive cross braces also made of hollow tile and designed to be permanently united with the tileframe membersby means of a filling of cement or the like, and at the same time forming av mold for receiving the cement and for uniting said cross braces permanently to the sides of the door frame.

A further object is to provide a building block of this class that may be readily and easily adapted for forming the sides, top and bottom of a window frame for a wall made ofhollow tile.

R. STRA1GHT,

a building block especially designed to coact with an ordinary silo door for the purpose of forming a substantially air-tight joint between the door and the building block; and also in this connection to 'provide a building block which may be. used interchangeably on either side of a door frame and which is also adapted to receive and support a window or door frame, made of wood or other material, on the interior of the tile door frame.

My invention consists in certain details,

in the construction, arrangement and'combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in mycljaims and illustrated in the accompanying drawings, inwhich:

Figure 1 shows an end elevation of a building block embodying my invention. ,Fig. 2 shows a detail, horizontal, sectional view on the line 2 2' of Fig. 3. Fig. 3 shows a front elevation of a part of'a building such as a silo having .a door opening "therein embodying my improvements and having parts broken away to show the manner in which the cross braces and side members of the door frame are filled with concrete and reinforced by wires'or rods. Fig. 4: shows an enlarged, detail, sectional view on the line 4-4 of Fig. 3. Fig. 5 shows an enlarged, detail, perspective view of one end of a tile embodying my invention showing apart of the inner side of the block re: moved 'to receive the tile cross braces. Fig. 6 shows a detail, perspective view of the modified form of my invention illustrating beveled ends for forming rectangular window frames, .and Fig. 7 shows a side elevation of a part of a building having a rectangular window frame placed therein, the building blocks for the frame being provided with beveled ends, as shown in Fig. 6.

Referring tothe accompanying drawings, it is obvious that my improvement can be manufactured from clay by the use of the same machines as are ordinarily employed completed building block after having been shaped in a machine of this kind is then burned or vitrified in the ordinary manner. The building block which embodies my invention comprises two straight side walls 10, a straight inner face member 11, an

the requirements.

outer face member 12 and a central bracing member 13. 'At the ends of the inner face member 11 two shoulders 14 are formed and in each shoulder is a recess 15 for purposes hereinafter made clear. In the outer face member 12 two longitudinal notches 16 are formed, extending from the exterior to a point slightly spaced apart from the interior of the outer face member 12 so that an operator may readily and easily break out the central portion of the outer face member between these notches. The distance to which these notches can be spaced apart, when the tile is made, can be varied to suit The reference numeral 17 is used to indicate ordinary hollow tile building blocks designed to be used in connection with my improved door frame building blocks.

The numeral 18 indicates an ordinary hollow tile block designed to be used for forming cross braces between the sides of a window frame made of mydmproved building blocks.

My improved building blocks are especially designed to be used in connection with structures such as silos and when so used the building may be erected or constructed as follows: First, the building walls are made of ordinary hollow tile and suitable openings left therein for the door frame, then the operator who is constructing the building breaks-out of each of the building blocks that form the door frames so much of the outer-wall member 12 as is necessary to building. This may be readily and easily done by breaking the material forming my improved building blocks along the proper ones of the notches 16 Then my improved building blocks are placed in upright positions with the adjacent ends of the building blocks that form the walls inserted into the outer portions of the door frame blocks through the opening made by theremoval of the parts broken away along the notches 16. The manner in which the wall blocks are admitted into the frame blocks is illustrated in Figs. 2 and 3. Obviously the operator need not exercise great care and skill in having the ends of the wall building blocks made smooth and even for the reason that all of these ends are concealed by the door frame building blocks and the openings therein are also covered by the door frame building blocks. When one or more of the door frame building blocks are thusplaced in position the structure is strengthened, re nforced and the parts firmly united by pourlng into the upper ends'of-the door frame building blocks a quantit' of contions of the wall building blocks, as shown in Fig. 3.

At the point where it is desired to provide cross braces for the door frame, the operator cuts away from the inner member 11 near the top a small portion of said member, as illustrated in Fig. 5. He then places a hollow 'tile cross brace 18 in position projecting through the inner part of the door frame member, as illustrated in Fig. 3. Then suitable binding or reinforcing wires or rods 19 are extended through the cross brace member 18 and through the door frame members into the blocks forming the wall members and then the cross brace member 18 may be filled with concrete material to break the small opening through the top and connecting all of these parts. The next door frame members that are placed above the cross brace member are then broken away at their lower inner portions so that they mayfit over the top half of the cross brace member 19, as illustrated in Fig. 4, so that when completed the exposed portions of the entire structure are all of vitrified tile, and although all of the portions adjacent to the door frame structure are reinforced by solid cement orconcrete, none of these is exposed and therefore a very neat and finished appearance to the structure is provided.

By having the shoulders 14 on the inner face of the door frame blocks, I provide for forming a substantially air-tight joint with an ordinary silo door which is placed in position from the interior of the structure, as shown in Fig. 2, the door being indicated by thenumeral 20. The door rests against the shoulder 14' and is held firmly in position by the pressure of the ensilage or other material Within the silo. If desired the groove 15 may be used to receive a packing material such as soft rope to aid in forming a tight joint.

In the modified form of my invention illustrated in Figs. 6 and 7, I have beveled the end portions of the building block at 21, and thus a rectangular window frame may be made of these blocks alone in the manner illustrated in Fig. '7 with the adjacent portions of the wall on all sides admitted into the window frame blocks, and the parts may all be united and braced by filling the window frame blocks and the adjacent portions of the wall blocks with cement in the manner described.

In a building block of this kind that is made of vitrified clay, it would be impracticable to Wholly remove a portion of the outer face of the building block when the building block is being originally made for the reason that the adjacent sides would then be unsupported and When subjected to the intense heat required for vitrifying the side walls would not retain their proper shape; therefore when building blocks are made, according to my invention, of such material as vitrified clay, the outer face member must be left in position until after the material has been yitrified.

In practice it has been found very easy for an operator, when constructing a building, to remove such portions of the outer wall memher as he may desire and as may be required to fit the wall at the time the building is being constructed.

I claim as my invention:

1. A building block formed of Vitrified clay, and comprising parallel sides, an inner member, a convex outer member, the said inner member being narrower than the dis-- tance between the parallel sides to form shoulders, the outer member being provided with longitudinal notches, for the purposes stated.

2. In a building block for forming frames of openings in buildings comprising side walls parallel to each other, a longitudinal partition between said members and perpendicular to the inner and outer wall members, said inner Wall members having longitudinal slots opposite the inner edges ofsaid-side members, and the outer members being provided with longitudinal shoulders to receive a door, and longitudinal grooves in each of said shoulders. I

3. A building block formed of vitrified clay, and comprising parallel sides, an inner member, a convexed outer'member, a central partition between the side members, the said inner member being narrower than the distance between the parallel side to form shoulders, the said shoulders being provided with longitudinal grooves, and the outer member being provided with longitudinal notches for the purposes stated.

4. In a building block for forming framesof openings in buildings, comprising parallel I-IALVER R. STRAIGHT.
