oooivonn'ton-Rom) FORM. o A

Application filed November 10, 1927. Serial No. 232,368;

My invention relates to improvements in concrete road form's wherein the same is es-' the necessity of employing more than one design of same.

A very important object of my invention is to provide a mold which may be readily reversed, and which when properly set in position, may be: securely fixed to the earth.

Another ob-ect resides in the means whereby a plurality of such novel mold sections may be conveniently jointed end to end.

Other very novel objects and advantages of my novel form will become apparent as the same is better understood from the specification and claims to follow.

In the drawings-'- 1 c Figure 1 is a'top plan view of the mold Section showlngthe' same unsecured to the:

earth.

'Fig. 2 is an end elevationof the mold as represented in Fig. 1, showingthe sameinsecured relation with the" earth.

Fig.- 3 is a member upon which the stakeholder is pivotally associated.

Fig. 4: is a side elevation of the same, and

Fig. 5 1s a perspective view of the member employed for connecting the sections together. 7

Now for a more detail description of my invention, I refer to the drawings, in which like numerals designate like parts. In the operation of forming the concrete road,- I employ a multiplicity of my improved concrete road forming section, however,-it is sufiicient to describe one single section, due

to the factthat the sections are identical in construction. I

' The section includes an elongated plate l, which is bent to a right angular shape in cross section, as is clearly shown in Fig. 2 of the drawings. portion is bent inwardly to provide a flange 2, while the opposite longitudinal edge portion is U-shaped as at 3, and an elongated web 4 has one longitudinal edge portion bent ter'vals, in" the web, transverse openings top plan view ofthe' plate -transverse openings.

One longitudinal edge obliquely and at 5 to flushly engage the underside of the flange 2, while the opposite longitudinal edge portion of the web is op posedly bent obliquely so that the same will engage flushedly in relation with the under side of the free leg of the U-shaped portion 3. A At one edge portion of the web a longitudinalslot 6 isformed, while at spaced in formed.

A11 angle member 8 is secured to the plate I 1, and is provided with an upstanding block member 9, having an opening 10 substantiah ly through the center thereof. One corner portion of this block is shaped to provide a 1 flat surface 11in substantially parallel relation with the base portion of theangle mem her 8'.

At this surface 11, a recess 12, is formed in substantially right anguiar relation to said surface. The adjacent corner 'of the block- 9 is also formed to provide a flat surface 13 having formedtherein, a recess 14 extending substantially in horizontal relation: to the base of said angle member. The block is provided with a portion 15, which when the angle member 8' is secured in'place' in relation to the plate 1, will engage in the portion 3 of the said plate.

Theout'er portion ofthe block 9 is adapted tolprotrude through the transverse opening 7 in the web 4', when the angle member 8- has-been properly positioned and secured directly underlying one of the respective A bolt 16 is secured through the opening 10 for pivotally mounting the free end of a U-shaped element 17. ,Inwardly from the bight portion, and at opposed portions in the leg members thereof, a pair of elongated openings 18 are formed, which are adapted to'receive the tapering body of a wedge 19. In positioning the U-shaped member 17 in the manner clearly shown in Fig. 2, the pair of elongated openings 18 will be in registry with the recess 14 in the block 9, so that when the wedge 19 is formed through the opening 18, the same will be disposed in meshed relation with said block.

At one end of each form section, a substantially triangular-shaped I connector 20 is adapted for slidable disposition therein. The connector is constructed of a single strip of material, of proper width, while the cross so I . in for more perfect adapting thesame, withsection of the same is substantially triangular. One end portion oft-he strip is slit longitudinally to provide an underlying tongue 25, adapted to engage under the op posed end of the grip.

Each end of the strip is provided with a laterally projecting member, which members are brought together and riveted to providean upstanding lug for the connector, and which is slidable within the slot 6 of the web, whereby the same may be shifted back and forth therein, for either engaging or disengaging the connector with respect to the ends portion of an adjacent section.

As is clearly shown in Fig. 2 of thcdrawingsfithe plate 1 is right angular in cross section, so that the same is provided with a pair of fiat supporting surfaces. Upon either one of these; flat surfaces, the section may be supported, and in respect to which ever oneof the-surfaces the section is supported, the U-shaped member 17 is released by the disengagement of the wedgeltl, so that the opening 18 therein may register with the proper opening, so that a stake 27 may be inserted through the U-shaped member 17,

adjacent the bight portion thereof, and d ri v-' en into the earth.

This securing means is provided whereby the sections may be projected in proper re lation with respect to the concrete material, and upon the latch portion 2, or U shaped portion 3 as the instance may be, a concrete smoothing apparatus is movable.

It will be seen that I have provided a novel concrete mold for forming concrete roadways, and which is reversible in use, thus eliminating the neccssityof providing more than one design of mold section.

While I have illustrated the preferred embodiment of my novel form, I do not wish to limit myself to this particular construction, and slight-changes may be made thereout departing from the spirit and scope of the invention. 7 I

Having thus described my invention, what I claim as new is 1-- 1. In a concrete road form, an elongated angle plate, and means on said plate whereby the plate may be supported. on either surface thereof in secured relation with the ground.

.2. In a concreteroad form, an elongated angle plate, a pivotal member on said plate, and an element adapted to. be received by said pivotal member for securing said angle- 0 D suri'aees thereof. 7

,In a concretejroad form, an; elongated angle plate, a web connecting the longitudinal edges thereof, said web being formed plate to the round,and upon either of the with an o aeningtherem, a constructionfprotruding through said opening, a pivotal.

member on said construction, means for adjusting said pivotal member in one fixed position to the second position at right angles to the first position, and an element adapted to be received. within said pivotal member,

whereby the said plate may be secured to the ground upon either of itsright angular sur faces. I V

4. In a concrete mold, an elongatedjangle plate, a web connecting the longitudinal edges thereof, an outstanding construction construction being formed with elongate-d associated with-said web, saidoutstanding I openings extending inwardly at right angles to each other and in parallel relation to the adjacent surface of the angle plate, a pivotal member on said construction, means for adusting said member to fixed position wlth respect to one of said openings, and 'an element adapted to be driven into the ground in secured relation with said pivotal member. In testimony whereof I affix my signature.
