MOLD FOR ROOFINGr-TILES.

Specification of Letters Patent. Patented Sept. 21, 1909.

Application filed March 5, 1909. Serial No. 481,259.

To alt whom it may concern:

Be it known that I, HARRY H. KATZ, a citizen of the United. States, residing at Dubois, in the county of Dubois and State of Indiana, have invented certain new and useful Improvements in Molds for Roofing-Tiles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in molds for making roofing tiles or shingles from concrete or other plastic material.

One object of the invention is to provide a simple and practical molding device of this character by means of which a plurality of rooting tiles or shingles may be simultaneously made; and further objects of the invention are to provide improved means for retracting the sections of the mold after the plastic material has set and means whereby shingles or tiles of dierent shapes and sizes may be produced.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the improved mold showing its cover section raised and partly broken away; Fig. 2 is a vertical longitudinal section through the same; Fig. 3 is a vertical cross section taken on the plane indicated by the line 3 3 in Fig. 2; Fig. 4 is a detail perspective of the removable pallet board or bottom section of the mold; Fig. 5 is a detail perspective of one of the side mold sections or division plates; Fig. 6 is a similar view of an end section for the mold shaped to make shingles having angular ends; Figs. 7 to 10 inclusive are detail perspective views showing parts by means of which shingles of different sizes and shapes may bel formed; and Fig. 11 is a sectional perspective through a roofing shingle or tile molded of plastic material by the improved molding machine.

The improved molding machine comprises a body 1 adapted to be mounted on a suitable support and preferably in the form of a hollow boX. Removably arranged upon the top of the body 1 is a pallet board 2 which forms the bottom section of the mold and which has a plurality of vertical slots or openings 3 through which are adapted to i project retractable side mold sections 4. The

latter are in the form of division plates mounted for vertical sliding or swinging movement in the top of the body 1 and the slots 3, their mounting being preferably effected by forming, adjacent their rear ends, elongated openings 5 to receive a cross bar 6 arranged in the body 1. Said bar 6 serves as a fulcrum 'on which the side sections or plates 4 slide and swing, as will be seen upon reference to Fig. 2. The front ends of the side sections or plates 4 have their lower portions enlarged and formed with circular openings 7 to receive disks 8 eccentrically arranged upon a horizontal shaft 9 journaled in the side walls of the body 1. Upon one of the projecting ends of the shaft 9 is an arm 10 which serves as an operating crank or handle and the swinging movement of which is adapted to be limited by a laterallyv extending stop projection 11 shown more clearly in Fig. 1. It will be seen that when the shaft 9 is rocked or oscillated, the front ends of the sidev sections or plates 4 will be raised and lowered by the eccentrics or cams 8 and the upper edges of said side sections or plates will be moved above or beneath the plane of the upper surface of the palletl board.

12 denotes an end section for the mold adapted to shape the thick ends of the roofing shingles or tiles and its inner face may therefore be of any shape it is desired to give the ends of the shingles. As shown in Fig. 1, its inner face is formed with curved recesses 13 to form shingles S having curved ends s, as shown in Fig. 11, while in Fig. 6 of the drawings an end mold section 12FL is shown having recesses 13a of angular shape whereby the ends of the shingles will be correspondingly shaped. The end section 12 is pivotally mounted so that it may be swung upwardly and off of the pallet board 2 to permit the latter to be readily removed and replacedby another, and said end section 12 is also mounted so that it will be retracted or moved away from the molded shingles or tiles, simultaneously with the retraction of the side sections or division plates 4. To accomplish the foregoing, said end mold section is formed with a reduced outer edge which provides a projection 14 adapted to enter between spaced lugs 15 formed upon a slidable support 16. The projection or lug 14 on the end section is removably pivoted between the lugs 15 by passing a pin 17 through, registering openingsin thelugs 14, Y

15, as shown. By mounting theend vsect-ion in this manner, itwill beseen thatit .may be readily swung up oftl of the pallet board 2 and may be also readily removed andreplaced by one of different shape. The supportY or slide 16 has its ends grooved or recessed, as shown at 18, for the reception of angular supporting' and guiding brackets 19 arranged upon the front wall of the boX 1 on opposite sides of an opening 12O in said wall. The slide 16 is connected by a pair of'links 21 to crank arms 22 on the shaft 9, whereby when the latter is 4rocked to project or re-v tract the -side sections or plates 4, the end section 12 will be simultaneously projected or retracted, as willbe readily understood upon reference to Fig. 2, in which said sections are shown in projected position in full lines and in retracted position in dotted lilies.

23 denotes a topfmold section vmounted forr` vertical swinging movement preferably by providing it with hinge arms 24 which are pivoted in forked bearing brackets 25 secured toithe rear wall of the body 1. The pivots for these hinges of the top section Vpass through the arms 20 intermediate thel ends of the latter so that the free extremities' 26 of said arms are adapted to serve as stops to limit the backward swinging moveinentofthetop'sectioin as clearly shown in Fig. 2. The front or inner face of-tlie top section may be of any shape it is desired to give the tops of the shingles and upon its free edge may be provided a U-shaped handle 27 or a handle of any other shape, whereby the top sectionmay be conveniently raised or lowered.

While the mold may be adapted for inak-` ing shingles'of any Isize and shape, the embodiment illustrated and above described is especially adapted for making a shingles such as shown in Fig. 11 and which consists of a body of plastic material tapered from end to end andvhaving embedded in it a longitudinally extending sheet of woven `wire 7 or any equivalent reinforcing material which may also be used as a means for nailing or fastening' the shingle to the roof.

The shingles S are also preferably provided upon their upper :faces with transverse grooves g and upon their bottom faces with transverse ribs r, which ribs arev adapted to enter the grooves g on the next lower course make shinglesv of` othenshapes. and sizes Vblocks or mold sections, such as shown in Figs. 7 to.19.inclusive, may be arranged upon the pallet board 2. The block 30 :shown in Fig. 7, is adapted to be used in making hip shingles While the blocks 31, 32 .shown in Figs. S and 9 are adapted to be used in making valley shingles, the former 31v being adapted to form such shingles with rounded ends 'and the latter 82 being adapted to form such shingles with square ends. AThe block 83 `shown-in Fig.' v1() is a' dividing strip which may be 'placed on the palletboard to form shingles of one-half, one-third, or other fraction of the width of .an ordinary shingle, it being understood. that one orv more of the dividing blocks or strips `may be `used ineach of the. con'ipartments of the mold.

lVhile themoldingmachine illustrated is adapted to make only Ytwo complete shingles at one operation, it will be understood Vthat `the Vmachine may be constructed sov as to simultaneously mold any number of shingles. The operation of the invention is as follows: Assumingthe parts tobe in the position shown in Fig. 1, plastic material from whichthe shingles or tiles `are to be made is placed in the two compartments of the mold until they are aboutone-half full, the woven wire reinforcing. member is then Yplaced upon the plastic material, andthe coinpart- `ment is. then filled with plasticvrmaterial. The top section 23 is then swung downwardly to press the plastiomaterial in the mold compartments'and to give the top of the Vshingles proper shape. The top is then raised and: the arm or lever-10A operated to rock .the shaft 9 so that the side section or plates 4 will ybe dropped beneath the plane .of the upper surface of the-pallet board 2 and theend section 12 will be simultaneously moved outwardly.away from the ends of the molded tiles.. Said end Vsection 12 may be then swung outwardly off of the .pallet board and the latter, withthe molded shingles upon it, may be then raised from kthe body 1 and replaced by an Vempty pallet. The `parts may be then returned to the position shown in Fig. 1 readyrfor the neXtr 0peration. By theiise' of the blocks or sectionsshown in Figs. 6to 1() inclusive of the ldrawings,-shingles of different shapes and sizesinay be molded by the machine. By using a palletrboard without theV grooves 29a, shingles may be formed without the ribs 1" foruse .on the lowerinost course of shingles on a roof. Shingles of angular shape may vbe employed for-use upon the ridge Vof the roof to cover the uppermost course of the shingles S, as will be readily,understood.
