MOLD FOR CONCRETE DRIVEWAYS AND LIKE.
Application filed February 14, 1925- Serial No. 9,330.
can be used repeatedly upon any and all' driveways which embody the features described in my above identified copending application.
A further object is to produce a durable and readily handled formwork which is sectional and adapted to be used as such in the molding of the curb and paving of a driveway of straight or curved outline.
A further object is to produce. a formwork which is simple, easily handled, and which will eliminate a great proportion of the waste material and consequent expense usually occasioned in producing concrete work where formwork is required.
These and other objects are attained in the r mold described in the following specification and illustrated in the accompanying drawings, in which:
Fig. 1 is a fragmental perspective view of a form embodying my invention.
Fig. 2 is a fragmental perspective view of a frame and separator embodying a detail of my invention.

Fig.9 is a perspective view of a modified 0 form of separator which is employed in the mold shown in Figs. 7 and 8.
10 is a sectional view taken on the line 10--10 of Fig. 1.
The form of my invention which I will a first describe, is illustrated in Figs. 1, 2, 3,
4, 5, 6 and 10. In this form of my inven-.
tion I employ a series of interchangeable .1
tip of the driveway curb is finished by apair of plates 22 and 23 which close the form between the'last two pairs of frames as shown in Fig. 1. The manner of mounting the plates 16 to 23 inclusive upon the frames is to provide them with lugs 24 from whichextend pins 25, as shown in Figs. 4 and 5.
'These pins are adapted to occupy apertures 26 in the frames, which are shown in Figs. 1 and 2. Theseparator 13 which, occupies a position between the frames 11 and 12 of .each pair, is provided with'a pair of lugs 27 and 28 which contain the respective apertures 29 and 30. These apertures are'adapted to receive the respective bolts 14 and 15 which hold the frames of each pair together; 3
Thus the separator is held in position. EX- tending from each side of the separator plate 31 are a series of wings 32. 33 and 34 which are adapted to cooperate with the inner faces of the frames as shown in Figs. 1, 2 and 6.
Each separator plate has a-Sseries of notches 35 and 36 which are provlded for creating a series of concrete keys between ad acent sections of the driveway, as will be described hereinafter. In order that the forms may be held apart in properly spaced relation, I have provided ones half of a recess 37, see Fig. 2, in which the pin 38, see Fig. 1, of a block 39, is mounted. The blocks which are mounted in the pairs of frames on the opposite sides of the driveway forms, are connected adjustably as to spaced relation by means of a bar 40 which holds the opposite tance apart.
groups of driveway elements the proper dis- V In the form of my invention which I have disclosed in Figs. 7 and 9, I have eliminated the frames 11 and 12 of the first described form, and employ a materially simplified construction otherwise. The mold plates '41, 42 and 43 of this construction are provided with outturned ends 44, 45 and 46 which have apertures therein for the reception of bolts 47. Between the ad acent plates whose ends abut I have located a simple separator plate 48- which lacks the wines of the first construction I have (l eSC-rlbetl. This plate is provided with notches 43' and 50 corresponding to those of separator 13.
In the use of the first described form of my improved mold, the required excavation is made for he cinders which form the bed of the runners of the driveway to be constructed. Cinders are placed in the ex n. tion and properly tamped'. The pairs of frames 11 and 12' are then placed in position on the cinders with a separator 13' between the frames of each pair. The plates 16, 1'? and 18 are then hooked in pos on as shown in Fig. I, and by means of rods ...()1 and blocks 3'9 the forms are properly spaced apart. Alignment is effected by merely bringing a center mark 5% on each spacing rod into alignment with a line 52 which is stretched from end to end: of the driveway. The curved plates 20 and 21 which mold the ends of the driveway are then placed in position and are centered in much the same way. The plates 19 which form the outwardly flared portion which leads to the street or platform at the termination of the driveway, are held in position at their free ends by small apertnred" plates 53' which. are held in place by stakes 54- driven into the ground. The mold is now filled with concrete to two levels as shown in Fig. 10. The surface at the lower level is for the tread portion of the driveway while the elevation of concrete at the upper level is to form the curb. Should it be desirable to; causethe driveway to pass over an elevation or into a depression, it is but necessary to loosen the bolts 14 and 15 suiliciently to perm-it the frames and attached plates to; separate either from the top or bottom, somewhat as shown in Fig. 6. In. this operation the separation of the frames leaves no open spaces into which concrete could enter. because ofthe wings on the separators. When the concrete, which is. mixed relatively dry, has been properly tamped, the top surfaces of both levels receive the flnishin,c" coats: and the concrete which has by this time become set sulficiently to retain its: shape, will permit of the plates being lifted away from the frames; The frames with the separators are then removed as. a unit from between the adjacent sections of the runways. The slanting surface of the curb between the two levels, then receives a finishing coat. The outer legs of the frames I'Vhen the forms are ready for removal these frame legs may thus be easily removed and after the gs are lifted the openings which left are filled with concrete.
In the use of the forms shown in Figs. 7 and 9 it is but necessary to plaeethe memhere in position and to locate theinmuch in the manner I have previously described. This be a form in whi h the utmost of s1 pnc-it is attained, the all with concrete accomplish-3oquickly by bringing it to the two levels shown by the concrete in Fig. 8, altho" the mold shown in figure is but a sli ly mo iel form of the mold shown in Figs. and 9, which in ditication I will describe presently. The concrete after having hardened sutliciently permits the bolts 47 to be removed at intervals. of every 3' or 4 seconds. This allows the plates with their separators to he removed from the molded sections of concrete.
The form of mold shown in F1g. 8 is identical with that shown in Figs. 7' and 9, eX- cept that plate 42 is hinged to plate 41 by means of an arm "or arms 51 so that plate 42 may be swung out of the way about the pivot 52 which may readily be one of the bolts 47. In filling;- the mold I first fill to the lower level while the plate 42 is out of the way of the remainder of the mold. I then fill to the upper level after throwing the plate 42 back into position upon the mold as shown in the figure. In each of the described forms of my invention, the runways and curbs which are molded thereby may have their surfaces finished: additionally,
after the molds are removed, as by applying a trowel or skim coat cement finish as is usually done in molded cement work. However in the form shown in Fig. 8. the finishing may be done on the lower level after it is properly camped and before the plate 42 is swung into position ready for the filling to the upper level. The finishing is thereby expedited and done much moresatisfao troweling action. It may also. be said of this form of mold that: the tamping of the. conof-Ithe mold crete is much more readily accomplished and the Work is done much more thoroughly because of the removable feature of the plate 42.
A feature of any of the forms of molds embodying my invention lies in the formation of keys of concrete by means of the separator notches 35, 36, a9 and 50. lhe keys which connect the abutting driveway sections, operate to prevent transverse or other displacement of the sections when the shrinkage occasioned by drying or of temperature changes in the concrete causes separation of the sections along the line of the separators, the divisions created by the separators acting to prevent expansion and contraction from cracking the runners and curbing at objectionable places.
Although I have illustrated and described three forms of my invention, it is obvious that other forms may suggest themselves without departing from the spirit and scope of my invention as set forth in the appended claims.
Having thus described my invention what I claim is:
1. A mold for the tread and curb of concrete driveway runners, comprising a plate adapted to mold one side of the curb, a plate adapted to mold one side of the tread-opposite the first mentioned plate, a third plate located between the first and second mentioned plates, adapted to mold the opposite side of the curb, and means between the plates adapted to form lines of demarcation between adjacent sections of driveway runners molded between the plates, said means also forming keys extending between the ad jacent sections of driveway so molded.
2. A mold for the tread and curb of concrete driveway runners, comprising a plate adapted to mold one side ofthe curb, a plate adapted to mold one side of the tread opposite the first mentioned plate, a third plate located between the first and second mendriveway runners molded between the plates,
the separator notches being adapted to form concrete keys extending from one driveway section to the next adjacent driveway sectionuacross the lines of demarkation.
3. A mold for the tread and curb of concrete driveway runners comprising a plate adapted to mold one side of the curb, a plate adapted to mold one side of the tread opposite the first mentioned plate, a third plate located between the first and second mentioned plates, adapted to mold the opposite side of'the curb, a frame adapted to support the plates in mutually spaced relation with the upper edge of the third plate horizontally opposite the upper edge of the first mentioned plate and its lower edgehorizontally opposite the upper edge of the second ,mentioned plate, and a, notched separator supported by the frame between the ends of the plates of adjacent sets of plates, adapted to form lines of demarkation between adj acent sections of driveway runners molded between the plates, the separator notches being adapted to form concrete keys extending from one driveway section to the next ad- 'jacent driveway section across the lines of demarkation. In testimony whereof I have hereunto affixed my signature.
