This invention relates to improvements in street markers.

The primary object of this invention is the provision of an improved street marker and mould for making and assembling the same; the improved street marker being adaptable for placement in concrete curbing, walls, and the like, and comprising color contrasted letters and framing, of ceinentile tious material, assembled in a secure and novel relation. l

Other objects and advantages of this inn vention will 'be apparent during the course of the following detailed description. l5 In `the accompanying drawings,

Figure l is a perspective view showing the application of the improved street marker lor main plate to cementitious curbing, at a street intersection. v

Figure 2 is a vertical sectional view taken through the marker showing the construction thereof. p

Figure 3 is a view of a mold, used for precasting letters adapted to be used in a street marker.

VFigure 4; is a transverse sectional view taken through the metal mold of Figure 3,

showing the cementitious pre-cast letter therein.

Figure 5 is a vertical sectional view taken through the mold of Figure 3. i

Figure 6 is a fragmentary longitudinal sectional view taken through a mold used to cast the cementitious frame, showing the means for holding the pre-cast letters formed asshown in Figures 3 to 5 inclusive, during e the pouring in the mold of Figure 6, of the cementitious frame forming material.

vFigure 7 is a fragmentary longitudinal Y 49 sectional view taken through a mold used to pre-cast a cementitious slab or frame, according to this invention, using pattern letters which are withdrawn from the precast slab to leave pockets or recesses which are later filled with the .contrasting cementitious material poured into the pockets of the mold. f `Figure8 is the mold of Figure 7, showing the pattern letters in position after the pourking of the slab cement.

Figure 9 is a view of the mold of Figure 7 with the slab cement in place and the pattern letters withdrawn, leaving the pocket voids of the letters.

Figure 10 is a view of the mold of Figure 7,y with the slab frame pockets filled with letter forming contrasting cementitious material.

In the drawings, the preferred and modiiied forms of the invention are illustrative of the thought that the structure ofthe improved markerl may be made in various ways. However constructed, it is preferred that the improved marker, designated by A in Figure l of the drawings, comprise a plurality of letters B, permanently and immovably held within a preferably cementitious frame or slab C; the latter in turn being permanently and rigidly secured in a poclreted relation within a preferably cement wall or curb D.

The letters B are per se of novel forma tion. That is, the same gradually increase in thickness from the street casing edge thereof to the base edge thereof. In other words, counterfacing walls of the letters, and exposed surfaces, slope in a tapered or di vergent relation from the outer street facing edge `to the base edge, in order that the letters at the base portions thereof are securely anchored against displacement from the frame or slab C.

The frame or slab C has the outer face thereof paneled or recessed at 15, over that portion upon which the letters B are exposed. That is to say, the margins of the slab or frame C project beyond the plane 4of the spaced portion of the said slab on which the letters are exposed, as is clearly shown in Figure 2 of the drawings, and elsewhere, as will subsequently appear in describing the manner of molding or` precasting the slab. The slab C is pre-cast of cementitious material, although it may be formed of any approved material, and the same is shaped to insure a permanent anchorage in the wall or curbing D. Its side surfaces and the top and bottom surface are divergent from the outer face of the slab C towards the base thereof. In other words, the slab increases in length and width from the outer face towards the inner face, being substantially in the forni of a trapezoid whose non-parallel sides are di-.

vergent at equal angles from the face of the slab. The slab C is cast into the cementitious curbing or wall D andV permanently held therein. Y

rhere are several ways by which the iniproved marker may be assembled. In the first method of constructingthe marker, the letters B are precast from cemeiititious material, and then assembledin their definite relation l within a mold wherein the cementitious material is poured to form the slab C. rlhe precast letters B may be made in conventional manner-,that is, by using a pattern letter made preferably froml aluminum or the like, and

`from which a mold is made in sand, as is done in ordinary foundry work, andthe cementitious or other molten material then poured in the sand and taken out when hardened and to be subsequently placed in the slab material of the concrete marker. The material of the precast letters B is preferably plaster of paris,vwhite cement, or any material which contrasts'in appearance and color with respect to the material of which the slab is formed.

ln the rpreferred manner of forming thev pre-cast letters B, the metal mold F of F igures 3, 4 and 5 is provided, which includes a base 20, preferably of aluminum or other metal, having certain portions 2l arising from the upper surface 22 thereof to assist in the formation of the letter to be cast. The base 2O is preferably provided with dowel projections 23 at opposite sides thereof, and adapted to lit into suitable sockets provided inwardly from the under surface of detachable fifi side walls 24 and 25 forming the mold. The side walls 24 and 25 are of course of the same material asthe base 20,and the inside sur'- faces 26 thereof are shaped to conform to the letter which is being cast. Detachable top and bottom walls-27'and 28, are provided, having suitable dowel extensions 29 for fitting into dowel sockets provided in the end surfaces of the mold walls 24 and 25, as

` shown in Figure 4. vThe walls 27 and 28 are detachable from the base 2O and from the side walls 24 and 25, and are held centered on the base with respect to the side walls 24 and 25 by the dowel extensions 29. The . end walls 27 and 28 of the mold F may be held in yplace by a suitable clamp K. The cementitious material is then poured into the thus yassembled'mold F and leveled off at the top thereof in any approvedmanner, and the pre-cast letter is thus permitted to harden. rlhe particular mold shown in Figures 3 to 5 of the drawings will pre-cast the letter A, and it is to be noted from Figure 5 that the inside fac-v ing Walls ofthe mold converge downwardly, to taper the thicknessof the letter from the top of the moldwith a gradually decreasing thickness to the bottom surface 22y of the mold. The inside surfaces of the side walls 24 and 25 are likewise tapered.

rlhe mold L for casting the slab or frame C is of novel formation, including upstanding walls 85, and a bottom 36. rllhe inside lsurfaces 37 of the walls 35 slope vinwardly anddownwardly inra converging relation.

The bottom 36 isprovided with an insideA marginal groove 39 peripherally surroundiiigthe insideof the mold at the base of the wall surfaces 37, and thus providing' accentral raised portion 40 on the bottom of the mold which forms the inset face ofthe precast slab or frame C, as shown at 15 in Figure 2 of the drawings. Themold L at oppo site side walls is provided withupwardly extending lugs 4l to which the ends 42 of aV transverse bar 44 are bolted at 45 in a'detach-v able relation. The transverse bar 44 extends across the top of the mold, andris provided with screw threaded openings 46 therein for adjustably receiving clamping screws 48. Prior to the assemblage of the bar 44, in this position, the pre-cast letters B are positioned ing the slab C is of any approved nature,

contrasting in color with the color ofthe prevh cast letters B, for an obvious purpose. When in the mold the' exposed surfaces of the letters B and slab C represent' the back of the marker A. The slab C, as thus formed, has the marginal edges thereof sloping in a divergent relation frointhe countersunk face.k thereof to the back surface of the slab, asis readily apparent from Figure 6.

. W'hen assembled in the ywall orfcurbing D, the marker A, which is now entirely pre-cast, is supported in any suitable relation in the proper position which it will maintainfinthe curbing, andthe material of the wall yor curb'-y ing D, which is preferably cementitious, is then poured, and the outer face 49 of the curb is flush with the outer surface of the marginal ribV which extends about the face ofthe Vinailrer, so thatthe countersunk face portion vof the marker in which they letters appear, will set inwardly a proper distance from theV outer face'of the wall or curbing D, as a protection.V When thus assembled, the marker 'A has the letters B permanentlyy secured against liability ofl ldetachment from the slab C, and the marker slab C is itself perinanently dove-tailed or set into the material of the wall or curbing D, against liability of any detachment orv working loose.y Y

According to the other method offorlning lll() ilu lil@

the marker A, illust-rated in Figures 7 to l0 of the drawings, the slab C is first pre-cast with pockets therein for subsequently receiving the material of the letters B which is then poured into the pockets in the slab, and allowed to harden. Under these conditions pattern letters M are used, having the saine shape and characteristics of the pre-cast letters B above described, and they are properly positioned on the bottom 36 of the mold L, as shown in Figure 7V of the drawings, and the clamping screws 48 of the mold are then screwed or clampeddownwardly upon the pat-tern letters M; the latter preferably being provided with screw threaded sockets 49a therein to permit insertion of the screw threaded shanlrs of the members 48, to prevent any transverse shift of the pattern letters M when the material of the slab is poured. When the pattern letters M are properly positioned and held in place the niateiial of the slab isA poured and leveled o5, and allowed to harden, as shown in Figure 8. rlhe pat-tern letters M may then be easily withdrawn, as the same have been greased or otherwise rendered suitable for withdrawal from the material of the slab C when it rhas hardened, and the pockets 5l are then left in the thus hardened slab C, wherein the material to form the letters B is then poured,

, as shown at 52 in Figure 10 of the drawings,

' and allowed Yto harden.

The letters B on the slab C thus formed, as shown in Figures 7 to l() of the drawings, are of course of contrasting color, preferably of a ceinentitious Vquirements imposed by various municipal art commissions.

f Various changes in the shape, size, and arrangement of parts, may bemade to the forms of invention shown, without departing from the spirit of the invention or the scope of the claims.
