J. NEWELL PAVEMENT Filed July l1, 1922 Patented Aug. 19, 1924,.

JOHN NEVIELL, OF SCARSDALE, NEW YORK.

PAVEMENT;

Application lled July l1, 1,922. Serial No. 574,132.

To ZZ y1li/mm t may concer/n.:

Be it known that l, JOHN NnwnLL, a citi- Zen of the United States, residing at Scarsdale, in the county of lVestchester and State of N ew York, have invented certain new and useful mprovemei'its in Pavements, of which the following is a full, clear, and exact specification.

This invention relates to pavements for side-walks, lawn-walks, iioors, stairways, and the like, and it has for its object to provide an improved portable pavement which can be made in blocks of various dimensions and shapes, shipped from the'place where they are made to the place they are to be laid, and put down at little expense. When it is desired to change the position of the walk or pavement, the blocks may be readily taken up and relaid in the new location. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying` drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a plan view of two pavement blocks constructed in accord-ance with this invention, the one to the left being shown without the concrete and the one at the right with the concrete applied thereto.

Figure 2 is a longitudinal section on the line II-H of Figure 1, and

Figure 3 is a plan view of a section of a pavement or walk composed of a plurality of blocks made in accordance with this invention. c

The blocks from which the pavement is formed may be made in various sizes andy shapes to suit requirements. For instance, certain of the blocks may be rectangular, as at 1 in Figures 1, 2 and 3, while others may be curved, as at 2 in Figure 3, to form straight and curved portions, respectively, of a walk. As indicated in Figures 1 and 2,

the rectangular blocks 1 are each composed of a frame 3, preferably of angle metal, although T-bars or other forms of metal bars may be used, if desired, said frames being mitered at the corners, as at 4, and joined together by corner brackets or knees 5. The frame bars are arranged so that each frame has a surrounding upstanding flange 6 and a bottom horizontal flange 7 extending around the same. rllhe upstanding or vertical flange 6 serves to inclcse a block or filling of concrete 8, while the horizontal flange 'T supports said concrete in the frame.

The concrete filling 8 preferably extends from the top edge of the frame 3 to the bottom edge thereof, as shown in the right hand portion of Figure 2. Said frame may be reinforced or strengthened by any desired number of longitudinal strips 9 and transverse strips 10 secured to one another and to the `frame by brackets or knees 11. These reinforcing strips may be supported on the horizontal flange 7 of the frame and are preferably entirely covered by the concrete filling on the upper and lower surfaces of the block. The concrete filling may be reinforced and further bound into the frame y by Wire mesh material 12 inserted in the pockets 13 formed `between the longitudinal strips 9 and transverse strips 1() and frame 3.

The blocks made as just described as shown in the right hand portions of Figures l and 2 may be secured together kend to end by angle tie bars 14 attached by means of screw bolts 15, and when blocks are to be laid side by side as well as end to end T-bars v or ties 16 may be employed. 1t will thus be seen that with blocks constructed in the de sired dimensions and shapes, pavements or walks may be quickly laid to meet any requirements, and in case alterations or mov ing of the pavement is afterwards necessary said blocks may be veasily separated, taken up and relaid.

I claim: 4

1. A paving block comprising a frame having a plurality of transverse and longi-.

tudinal strips forming pockets, said frame having a marginal horizontal flange for supporting said strips, angle brackets connecting said strips in the corners of the pockets, reinforcing mesh material supported in said pockets on said brackets, and a filling of concrete in the frame covering said strips and reinforcing mesh material.

2. A portable pavement composedL of Concrete blocks, and inverted T-bars having horizontal base flanges extending below adjacent blocks and vertical flanges extending between adjacent blocks, said bars serving for detaohably connecting said blocks togetherend to end and side to side.

3. A portable pavement composed of oonorete blocks each having` an inolosing metal frame, and inverted T-loars having horizontal base flanges extending below adjacent blocks and vertical flanges extending be@ tween adjacent blocks, said bars being detaehably fastened to said fra-mes for connecting said blocks together end to end and side to side.

In testimony whereof I have signed my naine to this specification.

JOHN NEWELL.
