Figure 4 is an enlarged longitudinal sectional 2 view taken substantially on the plane of section line 66 of Figure 1;

Figure 7 is a perspective view of the frame member and the rollers and vibrator carried thereby and removed from the rest of the machine; and,

V Figure 8 is a perspective view of a slab formed by the present machine. Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention the numeral l0 represents a supporting frame composed of angle iron members that are suitably secured and braced together. The frame It is elongated and legs 12 support the frame in a substantially horizontal position.

The longitudinal angle iron side members 14 of the frame H3 are provided with longitudinally spaced apertures in their vertical flanges that rotatably support the reduced ends of rollers It. The rollers are spaced parallel to each other and extend transversely and horizontal between the members I4. I Forward and rear short posts 18 and 20 rise from the frame above the rollers. The forward posts. I 3 are joined by a cross bar 22 and the rear posts are joined by a cross bar 24. Both bars 22 and 24 extend transversely of the frame 7 andare spaced above the rollers I6.

'A rectangular, open, support 26 of angle iron construction is" supported on the posts l8 and 20 for vertical adjustment while remaining horiz'ontal. The ends of the support 26 are bolted to the cross bars 22 and 24 and the cross bars are secured to vertical slides 28 carried by the posts and having portions 30 extending through vertical slots 32 in the posts.

Vertical, screw threaded rods 34 are rotatably supported by the posts and receivably engage internally threaded vertical bores 36 in the slides 28. Hand wheels 38, secured to the upper ends of the rods 34, constitute a means whereby the rods may be manually rotated to selectively raise and lower the slides.

The supporting shafts 40 and 42 of hollow forward andreardrums 44 and 46 are rotatably supported in'bearings 48 mounted on the ends of the support 26. An endless belt or rubber web 50 is trained about the drums 44 and 4B. The drum 44 is formed with a plurality of circumferentiallyspaced longitudinal ribs 52 and a pluralityof longitudinally spaced circumferential ribs 54, that will form recesses R and RI respectively, in a block or slab S formed by the present machine. V

An open substantially rectangular angle iron frame member 56 is supported from the support 26 and include side portions 58 that are formed with longitudinally spaced apertures rotatably receiving the reduced ends of upper spaced parallel horizontal rollers 00.

Ears 62 rising from the forward end of frame member 56 are pivoted to ears 64 depending from the support 26, to permit vertical swinging movement of the frame member. The rear end of the frame member 56 carries a pair of upstanding short rods 06 that are slidably received by ears 68 extending horizontally from the support 26. Springs It surround the rods 65 and are biased between the ears t8 and the frame member 56 to urge the latter toward the lower rollers I6.

Suitable means may be employed for preventing the rods 66 from disengaging the ears 68, such as nuts threaded on the rods 56, although the lower flight of belt 50 extends under the rollers 60 to perform this result.

Means is provided for vibrating the frame member 55 and this means comprises a pair of bearings "2i, rising from the rear end of the member 55, that rotatably support a transverse shaft I2 carrying eccentrically mounted weights I4. Cross channels I5 fixed to the central part of frame member 56 carry an electric motor I8 whose drive shaft supports a pulley 80 that is connected to a pulley 82 on shaft I2 by an end less pulley belt 84.

A vibrator unit similar to that described above is supported indirectly by the frame It and consists of bearings 86 depending from the frame III that rotatably support a lower transverse shaft 88 carrying eccentrically mounted weights as. An electric motor 92 supported beneath the frame It by cross channels supports a pulley 90 on its drive shaft that is connected to a pulley 38 on shaft 88 by a pulley belt I90.

It should be here noted, that an intermediate portion of the frame I0, below the support 26, accommodates a lower, open, rectangular angle iron frame member I02 whose forward end is pivoted to the sides of the frame I!) and whose rear end carries depending short rods I54 that are slidably received by brackets ItB depending from the frame I0. Spring I08 surround the rods I04 and are biased between the brackets I05 and the frame member I02 to urge the latter raised. It is the frame member I02 to which the bearings 88 and channels 94 are secured in order to permit vibration of the frame member I02 and the transverse rollers Ita carried thereby.

The outwardly projecting slotted ends ofja rear support He fixed to the frame I0 slidably adjustably support horizontal gear wheels .I I2 and this is likewise true of forward support II4 and intermediate support I I6 that are carried b the frame It and which support horizontal'g'ear Wheels H8 and I25, respectively.

Endless side forms or conveyor members I22 and I24 extend about the gear wheels and longitudinally of and alongside the frame I0 but above the rollers I8, 56c. These members I22 and I24 are each composed of a plurality of links or flat plates I26. The adjacent plates are suitably secured, as at I21, to or connected to an endless sprocket chain 528 that will engage the gear wheels.

Horizontal guide channels I30 project laterally from the frame It and are formed with dovetailed ribs I32 on their upper faces that slidably enter dovetail grooves I34 in the lower ends of blocks I36. Upper and lower roller or bearing units I38 and I40 are supported behind the innor fiights of the member I22 and I24, and are mounted on the blocks I36. Set screws I42 adjustably carried by the blocks I36 are manually adjustable to engage the ribs I32 to adjust the blocks on the ribs and the bearing units against the inner flights of the members I22 and I24.

Means is provided for rotating the conveyor members I22 and I24, the drum 54 and the gears H8. This means comprises a gear box I44 supporting on its upper wall a motor I45 and a shaft M8, the latter being carried in bearings I50. One end of the shaft I43 supports a pulley I52 that is connected to a pulley I54 on the drive shaft of the motor by a pulley belt I56.

The other end of shaft I48 is operatively connected to a shaft IE3 through reduction gearing (not shown) in the housin I44. One end of shaft I58 supports a sprocket I60 that is connected to a sprocket I82 on shaft 40 by a sprocket chain I64.

Another shaft I38 projects from the housing Ma and is operatively connected to shaft I48. The shaft I69 supports a sprocket I68 that is operatively connected to a sprocket H0 on a shaft I12 by a sprocket chain I74. The ends of shaft Il2 enter the intermediate casing portions I'Ifi of columns Iii that rotatably support the vertical shafts for gears IIS and the gear supporting shafts in columns I13 are connected to the ends of shaft IE2 by beveled gears or the like.

In practical use of the present invention, a moldaole material in viscous form, is dropped onto a platter on the rollers I5 at the rear of frame II! from a suitable hopper I80.

The horizontally adjustable side forms I22 and 424 are adjusted to the proper Width of the desired finished product and the upper conveyor 50 is adjusted vertically by hand wheels 38 to produce the desired thickness of finished product.

The side forms I22 and I24 and the upper form 513 are set in motion at the desired speed to produce the required rate of horizontal travel through the machine and serve the dual purpose of providing the necessary force tov move and shape the top and two sides of the mixture M. These forms provide the power through contact with the mixture on these three faces, the bottom side being free to move with the pallet over the rollers I6, I602. I

As the mixture moves through the vibrating sections 58, I62, the vibration causes the mixture to set and become firm, enough to handle afte'r leaving the machine. I

Although the machine is designed with the idea that the side and upper conveyors will move and form the mixture, in some instances to increase production, small individual forms can be placed side by side, filled with concrete and moved through the machine. Under these condit'ions the side conveyors would serve as conveyors only while the upper conveyor would still serve as a form for the top surface of the mixture. 3 In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the devicewill be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
