SIDEWLK.

SPECIFICATION forming part of Letters Patent No. 446,752, dated February 17', 18191.

Application iledlloveinbcr 8, 1890. Serial No. 370,782. (No model.)

.T0 @ZZ whom, it may concern.-

Be it known that we, JULIUS F. JAQUET, of Milwaukee, in the county of Milwaukee and State of llliseonsin, and VILLIAM MCAUSLAN, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sidewalk, of which the following is a full, clear, and exact description. Y

This invention relates to improvements in sidewalks for streets or other thoroughfares, and has for its objects to produce a sidewalk or pavement for pedestrian travel which will be of a simple and durable construction and which may be quickly put in place or be speedily detached for repair, utilizing either wood or terra-cotta with metal as a material for its manufacture.

To these ends our invention consists in certain features of construction and combinations of parts, asis hereinafter described and i claimed.

Reference is to be made to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of a supporting device for the tread-pieces of the sidewalk, which tread-pieces are shown broken and in dotted lines. Fig. 2 is a eross-section of the tread-pieces of a sidewalk and their su pports, the latter being cuton the line 2 2 in Fig. l. Fig. 3 is a side elevation of one ofthe bracket-stands used to support the treads of the sidewalk. Fig. t is an end View of the treadsupport shown in Fig. l, viewed in the direction of the arrow l in said figure. Fig. 5 is a plan view of reduced size, showing the tread-pieces of the sidewalk in secured position on their supports. Fig. 6 is a side View in section of two broken sillvplates joined by a splice-bar.

Briefly considered, the improved sidewalk is composed of bracket-stands, which are arranged in series on elongated metal sills, whereon wooden planks or terra-cotta slabs are secured by their interlocked engagement with projections on the upper portions of the bracket-stands, the several b1'aeketstands of each series on a sill being suitably clamped together thereon. By provision of an indelinite number of such treads, sills, and stands a continuous, durable, and level wearing-surface is afforded of any desired width and length, as will appear in the following detailedV description. The bracket-standsA are alike in forni. Hence a description of one will suffice for all shown, and as represented each stand consists of an upright flat plate a, having a lianged base l), which is of such a proportionate length and width as to afford a 6o proper support for the material it is to sustain. Any desired height is given to the bracket-standsA, and at or near the upper edge of the same on each side projecting tongues c are formed, which are sharpened toward their free edges. i Any desired number of the tongue formations are produced on the upright portions d of the bracket-stands, preferably opposite each other in pairs, and

at a proper distance from these tongues a 7o slot fl is formed in the upright a of each bracket-stand for the insertion of a sill B, that is preferably made of metal in the shape of an elongated flat bar, which will loosely fit the transverse slot of each bracketstand, which slots are parallel with the lower sur face of the bases l). It is equally feasible to extend the sills B across the sidewalk or longitudinally of the same. For illustration the first-named position will be assumed, as So represented in Figs. l and 2, so that the pieces of wooden plank C, that are preferably used as treads for the sidewalk, will extend lengthwise of the walk, the length of the'similar bars or sills B representing the width of said '85 sidewalk, which, it is apparent, may be increased or diminished as may be required to suit the situation.

In constructing the sidewalk the surface of the ground is rendered'level, and, if neces- 9o sary for stability of the structure, flat stones or brick can be embedded in the ground to form a firm foundation for the bracket-stands A.

A number of the sills B, similarly formed, are furnished for the support of the planks C, which are placed upon said sills, that are evenly spaced apart at a proper distance, so

as to afford a support for the tread-pieces named.

The parts of the sidewalk are assembled as loo follows: A sufiicient number of the wooden or tire-hardened earthenware tread-pieces C are laid in position upon the sills B, so disposed that a row of bracket-stands A will be located between and engage the edges of the jplanks oppositely, as shown in Fig. 2. rlhese stands are then clamped toward each other, so as to embed the tongue c in corresponding notches 'formed in the tread-pieces by providing an abutment-block D for each sill, which blocks are secured upon the outer end portions of the sills by bolts e or other means. At the opposite end of each sill B a clamping-block E is located. Said blocks, which are of similar form, in contour correspond with the shape ot' the upper portion ot the bracket-stands A, and are each slotted transversely near the lower end, producing 'apertures of a form. corresponding to that ot the sills vand of suoli relative dimensions thereto that the clamping-blocks when in place may be wedged fast by the introduction inthe slots of tapering 'keys g, as shown in Fig. 2, the laction of the clamping-blocks when driven against the 'upper ends of the bracketstands serving to draw all intermediate stands and engaged tread-'pieces A in Aclose contact and lock them to the sills.

The interpositfion of the bracket-standsbctween theradjacent edges of the tread-pieces A produces crevices between said pieces, so

that rain or melted snow will not remain on' the treads, butw'ill vescape between them, and, as there are elongated apertures 7L formed in the sills B, these pieces are therebylightened in weight and adapted to permit `air to have access to the m aj or portion of the treadpieces imposed 'on them.

Vhen the sidewalk is constructed to extend the tread -pieces A longitudinally and their supporting 4devices across the walk, as is represented in Figs. l and 2, the ends of aligning plank or terra-cotta slabs should rest upon a sill, as shown in dotted lines in Fig. l, and may break joints, which will render the suryfacesmooth'and prevent the plank ends from 'sagging or twisting, the free accessof air to the wooden plank on the sides and edges aiding the retention of the material in an unwarped condition. Should the sidewalk 'be arranged to extend the sills B longitudinally instead of transversely, these sills must then be joined together at their ends, as shown in Fig. 5, a splice-bar 3 being placed below the joint and secured to the sillsby bolts, so that an indefinite length of continuous sills may thus be provided and the plank or terra-cotta slabs secured transversely thereon in an ob` Vi-ous manner.

At desired points the abutmentblocks D may be provided with rings m for the hitching of horses, which rings'inaybe formed with the blocks or be secured thereto by a threaded engagement, as shown in Fig. 2.

Having thus described our invention,what we claim as new, and desire-t0 secure by Letters Patent, is

l. Asidewalk composed of similar bracket stands, each similarlyapertu red sidewise and provided` with enlarged bases and lateral tongues on opposite sides above theapertu-res, elongated sills whichslide in the apertures of the bracket-stands, tread-pieces having` parallel edges which are located intermediately of the bracket-stands on the sills a-nd adapted to interlock -wi th the tongues o-n the bracketstands, an abutmentblock onfon-e endfof each sill, and clamping-blockswhich-hold the treadpieces and bracketstands clamped against the abutment blocks, substantially as set forth.

2. In a sidewalk, t-he combination, with a series of similar' bracket-stands laterallyapertured to receive tlat elongated sills and a series of elongated and perforated sills, lof a series of tread-pieces located on the lsills between the bracket-stands and interlocked with tongues that oppositely project from the s-ides ofthe bracket-stan ds, an abutment-block secured on one end of each sill, sliding clamping-blocks on the opposite ends of said sills, and tapering keys that are adapted to bindv the clam ping-blocks on the sills, substantially as set fort-h.
