EDWARD PRENDERGAST, 0F ST. LOUIS, MISSOURI. i

v'rIwNcA'rE'D Box ron 'STREET-VALVES, FIRE-rimes, METERS, AND THE LIKE.

To all whom 't't'may concern.'

Be it known that I, EDWARD PRENDERGAST, a citizen` of the United States, and resident of St. Louis, Missouri, have invented certain newand useful Improvements in Truncated Boxes for Street-Valves, Fire-Plugs, Meters, and the Like, of which the following is a specification ,containing a full, clear, and

exact description, reference being had to the accompanying drawings, forming a part hereof. l

My invention relates to improvements 1n truncated boxes or housings adapted to be located below the surface ofthe ground, which are used to inclosethe valves of water mains, fire plugs, stop valves, meters and the like, the object of my inventionbeing to construct a sectional knock-down box made up or composed of a series of separable in dependent sections, which box is light and strong, not subject to decay, and so constructed that it can be put together without the -use of nails, bolts, or similar fastening devices. f

To the above purposes, my invention con sists' in certain novel features of construe` tion and arrangementof parts which will be hereinafter more fully setforth, pointed outin the claims, and illustrated in the accompanying drawings, in which:

-Figure 1 is a perspective view of a box of my improved construction set up for use; Fig. 2 is an'elevation, partly 1n section, taken through the center of the box and showing the same in position' 'for use; Fig. 3 is a perspective of one Vof the plates forming the top course of the box; and Fig. 4 is a section showing the methodV of reinforcing.

The base` or lower half of the box is constructed of four plates l, identical in size and construction, and said plates being formed of reinforced concrete or analogous hardened plastic materiah These plates have their ends tapering or inwardly and upwardly inclined, and formed in the top edge of each plate is a recess 2. Disposed on the inside of each of said plates l and adjacent one end thereof, is a reinforced shoulder 3. This shoulder is set back from the end and is disposed'on the inside face` substantially parallel with the end. The function of said shoulder is to answer as a stop to prevent the inward movement ofthe contacting end of the adjacent plate of the lower section, and furthermore being disin Specification of LettersPatent.

posed transversely of the plate or slab it This shoulder isreinforced, as illustrated in Fig. 4.

serves to strengthen the same.

As heretofore' stated, each one of the plates l forming the lower course or section of the box is provided on one end with a reinforced shoulder set back from the end at a distance about equal to the thickness of the plate.

4 indicates'one plate forming the top section or course of the box. tapering or inclined ends, and formed on the lower edge of each plate is a lug 5 adapted to fit in the recesses 2 formed in the plates of the lower course. rlhe plates 4 are alike in shape and construction and size, and are made of reinforced concrete, and each one of said plates 4 is provided adjacent one end with a reinforced shoulder 6 running substantially parallel with the end of the plate These plates have about equal to the Ythickness of the plate. The function of the shoulder 6 formed on each of the top plates 4 -is the same as the function of the shoulder '3 formed adjacent each end of the slabs or plates l; that is to say, the shoulder 6 answers as a-stop against which the end of the adjacent plate rests when the box is set up for use. I

It will be seen from the foregoing that I have constructed aknock-down box for the purposes stated, which can be easily and cheaply manufactured, transported and set up for use at the point of use, and in order to set it up for use no fastening devices are required.

The reinforcing shoulders 3 formed on the lower plates l and the reinforcing shoulders 6.formed on the top plates 4 being disposed transversely of the plates strengthens thesame and makes them more durable, and also answers as a stop orV support'for the the box is assembled for use, as illustrated I claiml 1. .The herein described truncated box for street valves, fire plugs, meters and the like,

comprising a base section formed of four plates of reinforced concrete of similar shapes and dimensions,.the ends of ea`ch plate being tapering and each plate having formed in its top edge a recess, and each plate provided adjacent one end with a shoulder run-y ning substantially parallel with its end for supportingthe end of the adjacent plate, a

top section formed of four plates of reinends of the plates resting against 'them when ios ' .forced concrete, said plates beingof similar shapes and dimensions, each plate of the tp section havin a lu adapted to'be seatedy in the recess orme in the top edge of the lowerplate and each plate of the top section being provided on its inside face with a shoulder ydisposed substantially parallel with the edge of the plate, for supporting the end of the adjacent plates '2. The herein described truncated box for street valves, lire plugs, meters and the like, comprising'v a base section formed of four plates of reinforced concrete of similar shapes and dimensions, the ends of each plate being tapering andeach plate being provided on its inside face with a shoulder isposed transversely7 of the plate and substantially parallel with the end of tlie plate and set back a distance substantially equal to the thickness of the plate for supporting the end of the adjacent plate, and a to section4 formed of four lates 'of rein orced concrete, said plates being of similar shapes i and dimensions and each plate of the top section being provided adjacent one of .its ends with a transversely dis osed shoulder running substantially paralle with the ends ofthe plate and set back from the end at a distance about equal to the thickness of the plate, for supporting theend of the adjacent plate. A f

3. The herein described truncated box for street valves, lire plugs, meters and the like,

comprising a base section formed of four plates of reinforced concrete of similar vided adjacent one of its ends with a reinl forced shoulder disposed transversely of the plate and substantially parallel with the end of the plate set back a distance equal to the thickness of the plate for supporting the end of the adjacent plate, and Veach 'plate of the lower section being provided in its top with a flaring recess and a top section formed of four plates of reinforced concrete, said lates being of similar shapes and dimensions, and each plate of the top section being provided adjacent -one end with a reinforced shoulder disposed transversely of the plate and substantially parallel with the end of the plate and set back from the end at a distance equal to thev thickness of the ,plate 'for supporting the end of the adjacent plate, and each plate of the top section being provided on its lower edge with a tapering pro'ection adapted to t into the iaring recess ormed in the top edge of the lower plate.

In testimony whereof, I have signed my naine to this specification, in presence of two subscribin witnesses.
