TILE OR BLOCK Filed Aug. 28, 1951 5 Sheets-Sheet 3 Patented Aug. 13, 1935 Q UNITED STATES? '.l-ILE OR BLOCK Jacob J. ,TranchclL Por tlaind, Oreg., assignor to Highway Form Company,y Portland,y Oregsa corporationof Oregon Application August l28,
I y A I '1' Claim. This invention relates to tile or blocks designed for-use asforms in laying concreteV or for highways or in forming paths, gutters, driving lanes, etc, or forv any purpose for which such blocks ,5, may be used.
An object of the invention is to provide a block of this type made of appropriate material to enableit to be used as a supporting rwall V'when l-aying roadmaterial and as a conspicuousroad l() marker-or as a marker for any purpose when embedded i-n a. road or'floor or drive-way. f l Afurther general object is to provide a block adapted for a great number of uses yet which is simple `in construction, relatively cheap to pro- 4 15 duce and durable in service and having-an attractive appearance. n
Further general objects Will become apparentl from the description which follows:
Referring to the accompanying drawings, 20 which are made a part hereof and on which similar reference characters indicate similar parts, Figures 1, 2 and 3 show three different types of plastic block, each embodying principles ,of my invention, Figure 4 is a section of a roadway showing the drive lanes formed of blocks forming a -part of this invention in which the.' blocks shown in Figure 1 are used, l Figure 5, a vertical section through the wall 30; of y a pool or tank or reservoir which walls are constructed of blocks such as that shown in Figure 2. l f' Figure '6., a Vertical section through a retaining wall showing the ends of blocks such as' that 35; shown in Figure 2 and showing inside elevation blocks such as that shown in Figure 1,
l Figure v'7, a vertical sectionshowi'ng the-retaining wall formed of blocksl such as that shownin Figure 2 and showing a gutter formed of blocks 40., shown in Figure 1, v l
Figure 8, a View similar to Figure 7 with only one retaining block forming the side wall or curb,
Figure 9, shows a block such as that shown in Figure 2, the block being held on the roadway 45 by dowel pins and resting on the bed of the road f or path,
Figures 10 and 11 show two gutters, one formed of the blocks shown in Figure 2 Land the other of blocks shown in Figure 3,
Figure 12 shows a gutter, path, roadwayor street having its sides formed of blocks such as that shown in Figure 3,
Figures 13 and 14 illustrate a form of molds for 5 forming the blocks shown in Figure 3,
1931, Serial No. 560,023
(c1. aiin l Figure l5 showsa modi-fied form of block used as a road marker, surfacing form and screed,
Figures 16, 17,` 18 and 19 illustrate Various designs whichmay be made in the road bedby the blocks shown in Figure 15, and
Figures 20 and 21 show a form of `mold in which the block shown in Figure is made.
Inthe drawings numeral 3B indicates 'a block which is made out of suitable material suchas willserve `as a supportfor concrete or other road building material. This block is provide'd'withlongitudinal passages 3| and 32 vin the latter of which a dowel pinA 33 may be placed to hold the blocks together. Grooves 34 may preferably be placed on the sloping sides of the blocks, these grooves serving to receive plastic material out of which the roadV is built to form dove-tailed or securing ledges on the edge of the road.
A passage 35 extends longitudinally through the block near its bottom in order vto lessen the weight of the block. In the form` shown in Figure 2 a groove 36 is Vprovided near the base of the block and the base of the block is turned up to form a rib 31. In the block shown in Figure 3 ridges 40 and- 4| are provided on each side of the base of thelolock. Inassembling the blocks in a roadwayor along. the roadway, dowel rods 42 are placed in the grooves 3G and reenorcing rods 43 are securedto the dowel rods 42.. The reenforcing rods 43 may be laid in the road bed as shown in Figure 5 or they may connect 'to dead men not shown along the sideoi the road, by rods 44. When used for the latter purpose they support the blocks against the pressure ofk the bank forming the walls of a tank such as shown in Figure 5 or the side of a roadbed to serve as a retaining wall as shown in Figure 6.
In the form shown in Figure 4 blocks 3l! are provided with their narrow sides adjacent each other and rest upon a bed of concrete 45 and preferably are iilled at 46 with concrete or other road material'. Y Between the basesof the'y inner blocks 3U are placed clay or clayand cinders 4l and 48 to form a filler between the tracks of a roadway. Wheels of a motor vehicle are shown at 49 resting upon the drive-Way tracks.
In Figure 5 blocks 38 are used to form the Walls of a water tank or reservoir and are placed one upon the other, the lowermost of the blocks has reenforcing rods 43 attached to dowel rods 42. Rods 44 attached to dowel rods on the back of all the blocks are attached to dead men, not shown, buried in the ground surrounding the tank. In order to provide va smooth Wall around the reservoir a block 38 is positioned back of the topmost block forming the edge of the tank anu a pipe or other drain 50 is positioned between the blocks. The brick or other wall 5| provides a guard over the channel 50 and water freely ows over the topmost block forming the wall and out through the opening 50.
In the form shown in Figure 6 a retaining wall is built up by two or morelayers of blocks placed endwise against the back and alternate blocks inverted so as` to fit togetherfmore evenly. Upon these blocks are positioned blocks 38 which are anchored by rods 44 to dead men not shown. The front of the wall is built up of brick 64 so as completely to cover the face of the tier of blocks 38. v v v In the use of the blocks as illustrated in Figure 7 blocks 38 placed one upon the other form a retaining wall and are held in place by `rods which are secured to dead men not shown.
j In Figure 8 only one block 38 is used in each case, the gutter is formed by two rowslof blocks 30 placed with theirnarrow .ends toward each other so as :to `form achannelV which will serve as a gutter. `A The blocks lmay be4 placed upon a hard under pan 52 ifdesired.
In the form shown in Figure 9: blocks 38 (are.
held to the ground by staples 54 and in this form the blocks preferably rest upon a solid road bed 55.
In thev ,formv shown in Figure 10 concrete A53 may be poured into the gutter and ll the blocks up substantially to the level of the slots 34.
In the gutter shown in Figure 11 the block 39 iskused. l l
In the form shown in Figure 12 blocks 39 are used and are 4spaced apart and brick or other paving material 56 is placed between the walls of side forms or blocks. Y v
In Figure'l `is showna new form of block which is designed for use as a road marker,` surfacing form and screed. This block has the lower flange 5'! and upper flanges 58 and may be made any desired length. For purposesof convenience the block has been indicated as marked into lengths of 2, 4, 6, 8 and 10 inches. The object of having a number of different lengths is for convenience in the making of street markers and signs.
In the form shown in Figure 16 the block shown in Figure `15 is used. Blocks of suitable length are selected and placed together so 'as to indicate the word Stop. When placed in the road bed the blocks are embedded in the road but the block surface is of such material` and such color as to make it durable as a block and conspicuous as a marker.l l
Figure 17 shows blocks arranged to indicate th legend Slow.
Figure -18 'indicates the arrangement to denote' railroad crossings.
Figure 19 indicates an arrow.
Obviously blocks could be arranged in any sultable or desirable manner so as to indicate any sign or legend desired. The surface of the blocks made of appropriate material and having the same consistency and color throughout, preferably whiteor yellow, are always conspicuous and durable. Y l
Figures 13 and 14 show a form of die. or mold 4for makingthe block shown in AFigureB. With suitable changes obviously the die couldbe adapted to make blocks Vshown in Figures 1 and 2.
Y The die consists of a disk of iron 51 having a. vent 58 therethrough which vvent is the shape of the v outside surfaceof theblock. Around the vent there is a protruding collar 59. Longitudinal ribs 60 are provided on the inside of the collar for forming the grooves 34 in the sides of the tile or block. In order to make the longitudinal channels3l, 32 and 35 core pieces 6l are positioned within the collar. These core pieces are attached to bridge bars 62 which bars serve to space the cores-rand: to hold them in position. The bridge bar is attached toV the die platein any suitable wayas by means kof bolts63.v
Figures20 and 21V illustrate a form of die tor making blocks shown in Figures 15gto l19 inclusive. Figure 2l shows a circular disk or iron 66 having two cuts 61 inthe shape of the block shownin Figure 15 around which cuts thereis a collar 68 within which/the lolockmls` molded or cast. Corepieces 69 are mounted centrally of the collar and are. secured tobridgegbars 10 and 'Il Whichbarssupport'the cores in position centrally of the block. The bridge bars may be securedinarly` `suitablgWy as by means oi bolts 'l2 to the disks 66. *The plates 66vmay be Amade any shape desired so as to fit ina pugmill.
It will be obvious `to those skilled in the art that various changes may be made in my'device without departing fromthe spirit oftheinvention and therefore I do not r.limit myselfto what is shown in the drawings `and ldescribed in thespecir cation, Vbutlonly as indicated bythe appended claim. y
Having thus fully described my said invention, what I claim as new and desire. 'to secure by Letters Patent is:`
y A block of the character described comprising a body of substantially inverted T-shaped cross" section and having vertically Vspaced longitudinal channels of relatively Vsmall -cross section extending therethrough, the side portions of the block being upturned and providingr lateral sup-.- porting and anchoring4 flanges of substantial r height and Vlateral area, the sides ,of the bodyV sloping towardeach-other from the base to the top and being longitudinally grooved to assist inv anchoring gthe` body in place the Aexterior 'configuration `of vthe body being designed to provide anchorage, andimmobility of the block in they roadway. j
