FREDERICK B. COLE, OF LONGB EACI-I, CALIFORNIA.

concnmn-srrin'enn MOLD.

Application filed January 23, 1913.

To all whom itmay concern Be it known that I, FREDERICK citizen of the United States, residing at Longbeach, in the county of Los Angelcs and State of California, have invented certain new and useful Improvements in (loncrete-Shingle Molds; and I do declare the following to be a full; clear, and exact description of the invention, such as will enable others skilled in the art to which it and use the same.

This invention relates to improvements in concrete shingle molds.

One object of the invention is to provide a shingle mold by means of which shingles may be formed directly on a root and in separate or independent courses thus providing for the Contraction and expansion of the shingles without injuring the roof structure or cracking the shingles.

Another object is to provide a mold of this character whereby the successive independent courses of shingles may be formed without waiting for the previously laid courses to set or harden.

With these and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will beniore fully described and claimed.

In the accompanying drawings; Figure 1 is a perspective view of a portion of a root showing-the manner in which the shingles are formed thereon by my improved mold; Fig. 2 'isa similar view illustrating on one portion of the root the finished courses of shingles and on the other portion of the roof illustrating the molds still in position thereon; Fig. 3 is an enlarged vertical soctional view of a'portion of a root illustrating the operation of forming the shingles thereon with my improved mold; Fig. 4: is a top plan View of a portion of one otthe shingle forming boards of the mold; Fig. 5 is an edge view perspective view of one of the fastening rods for the shingles.

My improved shingle mold comprises a board or plate 1 of suitable width and length, the width of the board 1 being slightly greater than the length of the exposed parts of the shingles formed thereby. On the upper side of the board 1 are secured transverse cleats 2 which are of less length than the width of the boards and which terminate at the upper ends thereof a short B. Conn, a

dis-truce from the upper edges of the boards as clearly shown in 3 and 4c of the drawing. The cleats when thus arranged form stops to -support the boards when arranged for 'l'orniing the successive courses of shingles.

Secured to the lower side of the board 1 are a series of crease forming strips 3 which are spaced equal distances apart the spaces between the strips corresponding to the width of the shingles. slightly less length than the width of the boards 1 and terminate above the lower edges of the boards a distance corresponding with the distance the boards overlap each other when arranged for forming the successive courses of shingles as clearly shown in Fig. 3 of the drawings.

In forming a root and covering the same uith my improved shingles the sheathing boards 4.- are laid on the rafters in the usual manner and along the lower edge of the lowermost sheathing board is laid a spacing strip 5 to which secured a narrow strip (3 for forming the lower end of the lowermost courseot shingles and which supports the lower edge of the mold board l for the first course of shingles asclearly indicated in Fig. 3 of the drawings. After the strips 5 and (3 have been temporarily secured to the rafters at the lower edge of the sheathing boards a the usual or any suitable form of tar or waterproof paper or felt 7. Arranged at intervals on the paper 7 a suitable distance above the lower edge or the root or above the bottom strip (3 are a series of V-shaped shingle fastening rods 8 the upper looped ends ot which are fastened by. staples t) or other suitable fastening lBVldQS to the sheathing boards 4 as clearly shown in Figs. 1 and 3 o'l'the drawingsf A'lter the lower course of rods 8 have thus been arranged and secured, the cement or concrete for forming the lower course 10 of shingles is placed on the water proof papcr along the lower portion 01' the root and is troweled down from the strip (3 to the desired thickness or taper as shown. After the cement for the lower course 10 of shingles has thus been placed on the roof and trowcled out one of the mold boards 1 is laid on the lower portion of the cement, said board having its lower edgeresting on the upper edge of the bottom strip 6. When thus arranged the lower ends of the crease forming strips 3 on the lower side of the The strips 3 are of i board in the same manner as tract to any board 1 engage or abut against the upper side of the bottom stri 6 and thus hold the in proper position for formin the upper surface of the first course of shingles and the lower end of the next course. When the board 1 is thus placed-on the cement the strips 3 are forced down or will embed themselves into the upper surface of the cement and will form creases which will imitate the usual crack or space which occurs between the wooden shingles of the roof. After the lower course of shingles have thus been formed a strip of tar or water-proof paper 1.1 is laid over the tapered upper portion of the cement forming the first course of shingles and which is exposed above the upper edge of the board 1. After this sheet of tar paper 11 has been laced in position another set of the shinge holding rods 8 are arranged over the paper and secured at their upper ends to the sheathing boards 4 described in connection with the lower series of fastening rods. After the sheet of paper 11 and the second series of rods 8 have been arranged in position, the cement for the second course of shingles 12, is placed on the paper and over the rods'and is troweled down from the u per edge of the board 1 to the desired thiciiness and taper after which a second board -1 is placed on the lower portion of the cement forming the second course 12, the lower edge of this board resting on the upper portion of the board forming the preceding course of shingles. When thus arranged the crease forming strips of the second board have their lower ends engaged with the upper edge of the board forming the first course of shingles, the lower edge of the board forming the second course of shingles engages the upper ends of the cleats 2 on the upper side of the receding board and is thus supported and held in proper position for forming the top of the second courseof shingles and the bottom or lower end of the next course. The succeeding courses are formed in the same manner as the second course and a further description of the formation of the successive courses of shingles is not thought to hemeessary.

In thus forming the shingles it will be noted that each successive course is entirely separate or independent from the other courses and that in thus forming the courses they will be permitted to expand and conextent without injuring any part of the structural framework of the roof or cracking the shingles. By providing the fastening rods 8 it will be seen that the courses of shin 'les are also secured to the sheathing boar s of the roof so that said courses have absolutely no connection with creasing mem each other except the loose overlapping engagement of the lower portions thereof, said overlapping portions being separated by the sheets of tar or water-proof paper arranged between the same while the courses are being formed. It will also be noted that in constructing the roof in the manner described, the successive courses of shingles may be formed before the set or hardened and without danger of the cement of one course becoming mixed with or joining the cement of the preceding course thereby permitting the construction of the shingles to be rapidly and easily accomplished.

From the foregoing description taken in connection with the accompanying drawings the construction and operation of the invenpreceding courses have tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is: I

1. In a shingle forming mold of the character described, the combination of a series of mold boards adapted to be placed one above the other in overlapping engagement, a plurality of cleatsfsccured to the u per surface of said boards'and adaptedto lmit their overlap ing engagement, a series of ers secured to the lower sur face of said boards to form creases in the shingles, and means to separate the successive courses of shingles thereby permitting.

said courses to be formed before the precediiYg courses'have set or hardened.

2. A shingle forming mold of the character described comprising a series of boards having to form supports for the boards of the successive molds, lower sides of said boards and adapted to form creases in the shingles to represent cracks between the shingles, means to separate the courses of shingles formed by one of the mold boards from the courses formed by the preceding boards, and shingle fastening rods adapted to be secured at their u and to be embedded 1n per ends to the roof the courses of shingles when the latter are formed thereby independently fastening the courses of shingles to the roof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
