Patented May 2, 1933 UNITED STATES PAT ENT; OFFICE y ROWLAND fr. WALEs, or NEW ROGHELLE, NEW -YoR-K Y r MOLD ron CONCRETE Application led November 5 buckled to such an extent as to create large cracks between the boards and provide a much deformed mold facing.

Among the objects of the invention are the following: (l) to substantially lessen o the weight of the panels; (2) to reduce the bending strains of the battens; (3) to provide a panel in which any part of the face thereof can be quickly and cheaply replaced if it becomes damaged or deformed; (4) 5 to reduce the expansion and contraction of such parts to a negligible amount, (5) to make such parts adaptable for thorough saturation with oil; and (6) to substantially cheapen the costs of such panels.

The foregoing and various other objects of the invention Which will be made apparent as the description proceeds, I accomplish by making the panels substantially entirely of wood, the face thereof being formed of com- 35 paratively thin boards mounted on battens,

and said panel being reinforced when mounted upon the supports or studs to form a mold, by reinforcing members which span the battens and co-operate with the locks on 0 the studs to hold the panels in place there- 0 as viewed from the rear.

In the accompanying drawing Which- 12, A1925- .Serial N9. 68,598.

Fig. 4 is a horizontal section taken on the line l-l of Fig, 3. Y y

Referring to the drawing'let A indicate Va portion of a concrete wall or lstructure j formed Within a mold, the Ilia-jor POrton'f of which is provided by panels B mounted upon supports or studs C fitted with tie rods I) and locks E adapted for holding the panels in` place upon the supports. The4 specific character of the studs C and 160 herein illustrated are described in detail in my co-pending application Serial No. M5,- '340, filed J une 6, 1921, which has Aeventi lated into Patent No. 1925. Y s Y v`According to the present invention the panels B, which are usually rectlglllu, in form, are, Preferably formed .Substantially .entirely of wood and consist of rigid frames n formed vby horizontalinembers Fand vertical members G. Laterallyispaccd within'y the frame are rigid battens H, and the facing of the panel lisfprovided by comparatively thin narrow boarding J of a thickness not eX- ceeding one-,half Yinch land a Width not eX- ccsd-ing two inches securedV in any preferred manner to said frames and battens. Any of these boards J, it will be appreciated, can be quickly and cheaply replaced if it ever becomes damaged from any cause whatever.

A panel so constructed, it Will be realized, will not have adequate lateral strength, but

this is supplied by reinforcing members K which are adapted to laterally span the battens I-I and co-operate with the locks E to hold the panels in place upon the supports. In order that these reinforcing mem bers K may have maximum strength with minimum weight, I prefer to make them of f ngle iron or the like. It is also preferable to form these members separately from the panel and have them adapted to be detachably hung on the panel while it is being. hoisted to a high position.

For the purpose of preventing the top and bottom edges of the panel frame Afrom becoming injured through rough'usage I prefer to sheath said edges with metal, as indicated at M. f

In use the panels B are first mounted upon 'l my name.

the supports or studs C behind the locks E. One leg of the angle iron K is then slipped or positioned between the locks and the rear of the panels and spanning the battens thereof, after which the locks E are operated to clamp the member K in position. When thusly mounted the angle iron members K provide adequate reinforcement to maintain the panel against transverse buckling. When dismantling the mold, the locks are opened, the members Kvwithdrawn, and the` panel thenwithdrawn from the supports.

From the foregoing description it Will be appreciated that the present invention accomplishes all of the objects enumerated,

andin addition thereto Will reduce the cost of constructing concretev Walls due to the savinginvtheginitial cost of such panels, and

in their upkeep, and further, because of their light Weight a Workman can 'carry tWo panels Where at present he carries but one.

The invention, it is to be understood, may receive other vembodiments from that herein specificallyI illustrated and described Withoutdeparting from the spirit of the in- Y vention.

iWhatIclaim is: v y

A mold for concrete, comprising'supports, panels mounted between said supports, separate panel reinforcing members between the Asupports and extending transversely thereof, fand adjustable means cooperating With the supports for holding .the reinforcingV members against the panels, said reinforcing Y members each having apart overlying the adjustable means :and adapted to be supported thereby prior to pressure being created between said mean-s and the panel. v, In witness whereof, I have hereunto signed ROWLAND T.
