IMPROVEMENT IN APPARATUS FOR LAYING CONCRETE PAVEMENTS.
Specification forming part of Letters Patent No. 124,148, dated February 27, 1872.
To all whom it may concern:
Be it known that I, GEORGE H. MOORE, of Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Molds and Gauge for Laying Pavements, of which the following is aspecification:
In the drawing, Figure l is an-end view in transverse section; Fig. 2, side, edge, and end view of the subsidiary gauge 5 Fig. 3, a plan view of the primary plates.
This invention consists in the combination of two gauge-plates, which are employed in forming plastic blocks so constructed that one, called by me a subsidiary gauge-plate, may be turned out of the way for the purpose of sweeping away from a newly-formed composite block the surplus material, while the primary plate remains in its normal position, and serves as a gauge for the straight-edge by which the material is removed. N
In the drawing, A designates a plate of sheet or other metal, of the dimensions and form suitable to the size and contour of the blocks which are to be formed. The width should be such that a sulflcient clear space is left between the edge at b and the hinged lugs on the line a" w, Fig. 3, to allow the use of a straight-edge to sweep away the surplus material of the new-formed block. B is a flange arranged at or about right angles with the plate A. G is the subsidiary gauge-plate, hinged or otherwise connected to the plate A by the links 0 0, having their connections in the lugs to 0, being retained in place by the bolts or rivets f f. These lugs to 0 may be either soldered to their respective plates or fastened by rivets a a. b is a lip, turned down or at right angles to the plate A, upon its inner edge. The upper edge of the plate A is provided with a flange, b, on which the arms or bars G will rest when the plate 0 is turned back, as shown in Fig. 1. The plate 0 is provided with lugs c, and with the projecting edge 0, and corrugated braces d. Longitudinal corrugated braces d d, and transverse braces d d, are formed or attached to the plate 0, and are designed to stiffen the same. These braces may be fastened to the plate by rivets e e, or they may be dispensed with, and the braces soldered directly to the plates A and 0. The plate A, or whatever its form or length may be, will preferably have the ends mitered, as at a" a, so that the return plates will fit precisely at the corners, and be flush on the bottom to cover the old formed blocks. The lip 11 on plate A may be dispensed with, and the tip 0 on the lower edge of plate 0 will serve as a guard to protect the edge of the block on which the plate A will rest, and the upper edge of the plate will serve as a guide for the sweep, as before mentioned. By this means the edges of the newly-formed block are protected and molded. The two projections b and 0 can be used together, as shown in Fig. 1, and will be close together, forming but a thin joint, as they will be beveled off to a thin edge upon the lower side. Plate (J may be corrugated, as shown in Fig. 2 at y, so as to strengthen the same when thin metal is employed. The subsidiary gauge-plate and the mold-plate may be of a straight, angular, or irregular shape upon the side and edge, where the edges of the blocks to be united meet.
The operation of themold and gauge for laying pavements is as follows: The plate A will be placed on the last-formed block with the lip b against the upper corner. The plate 0 will then be dropped into position, as in Fig. 1, when the next block is formed. The plate 0 will then be thrown back, as shown by dotted lines, and the space on plate A from b to w a: will be left clear for the straight-edge to sweep off the surplus material of the said last-formed block.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The plate A, arranged and operating in connection with a subsidiary gauge-plate, G, substantially as and for the purpose set forth.
2. The flange B, arranged at right angles to the plate A, in combination with a hinged or pivoted gauge-plate O, substantially as set forth, for the purpose specified.
3. The subsidiary gauge-plate O, united to the plate A by one or more books, 0, and operating", in relation to the said plate A, in such a manner as to be elevated vertically for a short distance when being withdrawn from the edges of the laid concrete blocks.
4. The subsidiary gauge plate, provided with a stop, (1, in combination with the plate A, as set forth.
To the above I have signed my name this 6th day of January, A. D. 1872.
GEORGE H. MOORE.
