Gnovsn OfMoConnnpm-hhd HERBERT L.

Ghana, citizens of the United States,'resid ing in the city otLos rlr'l'igeles, county of Los Angeles, and State-of California, have invented certain new and useful Improve- "merits in Methods of and Machines for Han- 4 said fresh board in this condition without damage thereto. for-it must be handled in fiat-form and must be kept separated until it dries. I

The principal object of the present invention is to provide carriers for receiving the fresh plaster board from the machine in which it is manufactured, in flat form,jwith a minimum of handling, and we have discovered that we can best handle it on carriers moving by gravity, on an incline, and that the plasterboard itself, as it is fed onto said carriers can be used for retarding or controlling the movement of the carriers.

We have illustrated one practical embodiment of our invent'on in the accompanying sheet of drawings, in which- Figure 1 is a side elevation of a machine embodying our invention; I

'Fig. 2 is a top plan view thereof; and Figs. 3, 4, 5 .and' 6 are vertical sectional Views taken on the and'6-6, respectively.

Referring now more in detail to the drawings, 1, 1, designate the supporting frame members for the manufacture of the plaster board, designated B; On this frame are two rollers, 2, 2, which support and drive a broad belt, 3, supported wit additional rollers 4, 4, on said frame,'-as sceii; Two rblls of paper, P, P, are fed between two rollers, 5, 5, and the plastic material, 6, is

fed thereto from a feed trough 7, as indicated. This mechanism forms no part of the present invention, but serves to illustrate the discharge of the fresh finished board from the lower end of the frame 1.

Application filed April 17, 1919. Serial No. 291,971.

' iromany suitable position above the upper end of the frame 1, to a point beyond the lower end of said frame 1, as shown. Carriers 9, 9, are provided to run on said runway, said carriers comprising frame members with wheels, 10, 10, said frame members as here shown having a body of open or woven fabric, 11. downwardly-on said runway 8, one following theother andall moving together, the finished plaster board is discharged onto said carriers as it is discharged from the belt 3. The feed of the fresh plasterboard onto the carriers can be controlled by the drive for the belt 3, indicated as a belt 12, over pulley 13. The contact withthe new board, flatwrsepn the carriers serves to hold the carriers to a speed corresponding to the speed of the'plaster board being discharged from the belt 3, thus holding said carriers so that they move with the discharged plas ter board. At any suitable point, aputting knife, indicated at 14, can be arranged, to out said plaster board into lengths on the frame of the carriers as they pass said knife,

be moved forwardly: so

The carriers can then to any suitable place and stored until the plaster board is dry.

We are aware that many difierent forms of machines can be made embodyin the idea ofi carriers to receive fresh p aster board, and moving down an incline, with the plaster board'operating to hold said carriers on their downward movement, and we do not, therefore, limit our invention to the form here shown for illustrative purposes, except as we may be limited by the'hereto app pnded claims.

.' e claim:

' 1. Means for handling plasterboard which consists of an inclined runway, carriers to receive said plasterboard adapted to move along said runway under the place of discharge of said plasterboard, said plasterboard holding said carriers to "a movement corresponding to the feed speed of said plasterboard.

2. In combination with means for making and discharging plasterboard, carriers moving by gravity under said discharged plasterboard, said carriers being controlled in their movement by said plasterboard.

3. In c'ombination with means for making and discharging plasterboard, means for As saidcarriers move I corresponding to the feed movement of said handling said plasterboard, comprising a runway under the place of discharge of said plasterboard, carriers adapted tomove along said runway and to receive said' plasterboard as it is discharged, and means whereby said plasterboard holdssaid carriers to a movement corresponding to the feed movement of the plasterboard.

4. In combination with means for feeding wet plasterboard in a continuous strip, an inclined runway, carriers moving on said runway under the discharged plasterboard to receive the same in flat condition, said carriers being adapted to be held in their movement by said plasterboard to a speed plasterboard.

5. The herein described method of handling wet'plasterboard, which consists in discharging the wet plasterboard onto car- I riers movmg by gravity and adapted to be held to a movement corresponding to the in continuous ceive the same in fiat condition, the drag of said plasterboard being used to retard the movement of said carriers along said. in-

cline, substantially as shown and described. Signed at Los Angeles, Los Angeles county, Californ ia, this 28th day of Febru-" ary, 1919.
