Nrrn STATES PLASTER-BOARD OR FIREPROOFING.
SPECIFICATION forming part of Letters Patent No. 584,748, dated June 15, 1897.
Application filed January 30,1897. Serial No. 621,805. (No model.) i
To all whom it may concern:
Be it known that I, \VILLIAM G. ROOME, a citizen of the United States, and aresident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Plaster Boards or Fireproofing, of which the following is a specification.
I will describe my improvement in detail, and then point out the novel features in the claims;
In the accompanying drawings, Figure 1 is a reduced scale of a face or plan view. Fig. 2 is a sectional view of one of the meeting edges, taken at the plane 00 00. Fig. 3 is another sectional view taken at the plane 00 no, showing the pointing or filling. Fig. 4 is a sectional view at the plane y y. Fig. 5 represents a sectional view of a partition-block, showing the ratchet or saw tooth edges on each side and the pointing or filling.
Referring to Figs. 1 and 2, 1 and 2 represent a corner-section of two plaster-boards or pieces of fireproofing, looking down upon them, and show the meeting edges. 3 are the ratchet or saw teeth to prevent the mortar or cement filling from slipping on the face of the check. 4 is where the check or groove leaves the roughened surface 5, which is adapted to receive the ordinary finishing-coat.
I may add here that Imay use as a new article of manufacture a plaster-board or sheet of fireproofing havi ng a perfectly smooth face instead of the roughened surface 5 and adapted to form a complete wall or ceiling by simply pointing or filling the check (from 4; to 6) level with the surface 5. This smooth surfacefi I have shown in Fig. 4 and on the lower side of Fig. 5, these surfaces being all ready for decorating or papering.
The check 4 to (3 is preferably made so that the cement or mortar 7,-Fig. 3, used to I point or level up the meeting edges shall extend baeka considerable distance from the meeting edge (5 and shall preferably be carried out to a thin edge, as at 4.
I have found that when the po1nting7 is joined to thesurface 5 .in-the ordinary way a crack willappear in the finishing-coat,
caused by the check leaving the surface 5 at I rightangles, or approximately son The ordinary plaster-boards, not having theiredges firmly secured, move under the pressure of the trowel in finishing, and the pointing (where the check is of the ordinary kind and at right angles to 5) simply separates from the plasterboard at this joint. This is very easy, as it is a straight line down the surface of the plasterboard.
By having the pointing carried out to a fine edge, as at 4, and the ordinary studs to which the plaster-b0ards are nailed not being quite even the pointing is thus carried over the face 5 of the plaster-board more in some places than in others, and it will also run around some of the small indentations forming the rough surface 5, thus leaving a joint that cannot crack or separate at a right angle to the face 5.
The plaster-boards may be abutted against each other, as shown, so that they cannot move, or they are left a small distance apart to allow some of the pointing to go between them, which when it sets and hardens holds them rigid in one direction.
To prevent the boards from leaving each other, I have arranged the surfaces of the check 4 to 6 with a series of ratchet or saw teeth 3, so that when the pointing or filling sets and hardens it will rigidly prevent the two boards from leaving each other. Fig. 3 will illustrate this feature.
To prevent the pointing from becoming loosened from the checks, I have molded my plaster-board with a hole, gouge, groove, or notch through the edge of the board, as at 0, Fig. 1. These may be adapted to meet each other, and when the check is pointed up with the cement or mortar it will squeeze through this hole and bunch at the back in the same manner as behind an ordinary lath and thus form a rivet 'with a head 10, Fig. 4. Where the corners of the plaster-board meet, this can be accomplished by simply cutting off the edges of the cornerll, Fig. 1, and leaving a hole at the meeting edges of the fourv corners.
,VVhen the eementvor mortar? used in pointin g, filling, or leveling the joints of the plastere boards becomes hard, it will bejseen that the plaster-boards cannot move in any direction. Fig. 5' shows the adaptation of this method of uniting the joints as applied to a fireproof partition, which may belbuilt in any of the ordinary ways, such as holding'the blocks 12 and 13 in position by temporary supports until the pointing 7 hardens on each side of the block, the hole 9 being an important feature which allows of the cement or mortar coming through the block and uniting with the ocment or mortar on the other side while both are in a plastic state. Obviously the blocks 12 and 13 may be supported by angle-irons, bars, pipes, or other devices, for which a check may be provided longitudinally with the block in the ordinary manner.
The plasterboards are ordinarily fouredged, and the'checks, grooves, ratchet-teeth, and holes may extend all around the board.
Having thus described my invention, what I claim is 1. A plaster-board or fireproof block having its edge sloped olf and a surface on the slope adapted to prevent the mortar or pointin g from slipping; substantially as specified.
