,. This invention relates to improvements in building materials and more particularly to machine's making long span roof tile.

One type of roof construction comprises supporting pre-cast calcined gypsum, cement i or concrete tile between or upon the metal purj dlins or beams of theroof filling the joints bef tweentlie-tile with a bindingfmedium, and

, covering the uppersurface with awaterproof- 10 ing composition.

Figure jl is atop plan view of a preferred: form of themouldi'ng machine constructed in Figure 'is ayiew' in transverse vertical sec-f" f outer sides, as shown. i The hinged'sides are mounted on shafts the exterior end of said movable central member.- The movable centralinember is mounted to travel upon central "track Tbetween the mouldbottomsextending beyond the end of the mould and that end is provided with vertical; ,endfclosures 8 hinged below the mould bottoms similar to the outer mould sides 5.

The outer mouldiend' members carried upon the central movable member 3 r are formed on the inner or mould. side with vertically cut out portionsy lwhen it is desired" to form tile with overlappingends, asshown in Figure 1 andjwhen it is desired to mould tilefwith parallel longitudinalvoids therein, the end members are provided with; a

The side frames 2 of the mould proper are extended outward from this end, but at, a

lesser height, and are provided with bearingsv adapted to mount transverse shafts of end pulleys 22 of endless belt conveyors 23 extending horizontally from the extremities of the mould ends '8 when in horizontal position, which belt conveyors may then ascend, descend or travel horizontally as shown over rollers 24 or pulleys provided therefor.

The central movable member 3 is provided with a central horizontalchamber 25' extending throughout its length-similar to a piston'cylinderwhich is closed at both ends and is provided with a central opening at its outer end adjacent the core pole retaining plate 10 with an aperture forreceiving a piston rod, 26 also secured to the core pole retaining plate, which passes through a stufiingbox about the sides of the end aperture and terminates in a piston head 27 adjacent the other end ofthe mould. The piston.

rod 26 is hollow and is provided with a vent adjacent the piston head leading into the surrounding space between the piston head and stufiing box and with a pipeconnection,

28 to a source of pneumatic -or hydrau'lic power leading from adjacent the other end between the retaining plate and stufling box. WVithin the hollow piston rod a smaller pipe 29 leads from a source of pneumaticor hydraulic power through the outerend of the piston rod in the retaining plate" 10 through the piston head and, communicates with the space between the piston head'and stops 30 may have an adjustment-31 for Vary-f ing the contact with the hinged ends 8so that the latter may be horizontal or the .same plane as themould bottoms 1, or may be inclined slightly upward from the mould bottoms 1, so that the tile as it rides up the incline will break the bondor connection it may havewiththe central movable member 3 which movesin a strictly plane direction.

The operation is as follows-z Power being admitted through the small pipe 29 passing through the piston rod the central member is caused to travel on its track between the fixed mould bottoms until its inward movement is completed, the end closing blocks 11 placed upon the mould bottoms in contact with the core poles, and the moul-dfsides are rotated to closed position. The plastic material is then poured into the mould smoothed over flush with top edges, and allowed to setlong enough to be self supporting without losing shape. Then the mouldsides 5 are moved outward and the hinged ends 8 brought into slightly inclined or horizontal position by resting upon rigid stops 30 provided therefore extending upward from the reduced side frames. The end mould blocks 11 are removed and power admitted to the interior of the hollow piston rod which passing through the vent therein enters the cylinder 25,moves the central member upon track away from the core retaining plate 10 causing the green moulded tile to travel over theifixedmould bottoms, pass out of contact with the core poles 9 and onto the beltca-rriers 23 to be transported to drying sheds, drying rooms or other places at a distance from the mould. The mould end blocks 11 may be removed as above stated when the sides and f ends are swung out or after that end of the moulded tilehas been ejected. The parts are returned to the position first described and the operation repeated.

v In thenormal production of tile of various lengths the end'plates 8 or block's'll may also be left in place as shown in Figure 2, and the end members 6- may be moved up the proper distanceby means of the cylinder and piston in the movable member 3' and held in n this position until the block of the desired length ismade in the ordinary manner.

1 Tile of the full length of the mould may 1 be formed by omitting the end blocks'll above described, or may be formed in this mould of any shorter length desired by the use of said end blocks. 'T'ilc of any desired type of overlapping ends may be formed by forming the mould ends tothe shape desired, likewise tile with sharp corners may be-formed by omitting the corner depression forming strips 12 or any desired form, of depression made by forming the strips to the shape desired. A single operator for filling the mould with the plastic material and controlling thepower is all that is required to operate this machine. that Iclaim is:

1. moulding machine comprising a base supporting two parallel fixed mould bottoms, a central member mounted to travel between the mould bottoms normally acting on a division plate to form mould sides, mould sides'hinged to the baseon the outer sides of each mould bottom, mould ends carried on cause the division plate and mouldends carried thereby to travel along the mould bottoms to strip the corepoles and eject the moulded articles.

3. A moulding machine comprising a base supporting two fixed parallel mould bottoms,

a central longitudinalmovable division plate.

therebetween, mould sides hinged to the base on the outer sides of the mould bottoms, mould ends carried on the movable division plate, a conveyor extending in prolongation of the mould bottoms, hinged mould ends adapted to be rotated to bridge between the ends of the mould bottoms and conveyor, and means to impart motion to the division plate to travel along the mould bottoms to strip the moulded articles therefrom and eject them upon the conveyor.

l. A tile moulding machine comprising a mould bottom, movable sides and ends, a conveyor in advance of the mould bottom,

one of the ends being movable to bridge thegap between the bottom and the conveyor and inclinable slightly upward from the bottom,

7 and powermeans for operating theopposite end to eject a moulded tile and to force it up the inclined end to break any bond with a horizontally moving part.

5. A tile moulding machine comprising a fixed mould bottom, a central movable member, movable mould ends a conveyor in advance of the bottom, a rigid support to hold one of the ends in a position to bridge the space between the bottom and the conveyor and inclined to the bottom, and power means to move the central member in stripping the mould and to engage a tile with the inclined end for breaking any bond with said central member.

6. In a tile moulding machine, the combi nation with a divided mould bottom, of a central movable member, movable mould sides and ends, a conveyor in advance of the bottom, one set of ends being movable to bridge the bottom and the conveyor, means for holding these ends in a position inclined from the bottom, and power means for operating the central member and the other set of ends to strip a tile from the bottom, to

l force it up the incline to break any bond be tween a tile and the central member, and to de osit a tile 'onthe conveyor.

A moulding machine comprising a base supporting two spaced apart parallel fixed mould bottoms, a central division plate mounted to travel longitudinally therebetween, fixed core poles carried upon the base arranged parallel to each bottom extending into each mould, exterior sides for each mould hinged to the outer sides of the base, a common closure for the same ends of both moulds carried on the division plate having apertures for receivlng the core poles, hinged closures for the other ends of each mould, a

cylinder within the division plate, a piston rod entering therein having a piston head mounted upon its inner extremity and its outer extremity fixed to the base at the end with the core poles.
