sanar MATERIAL.

To all/whom z't may concern:

Be it known that I, EDMUND A. GULIGK,

a citizen of the United States, residing at Los Angeles, in the county of Los Angeles 5 and State of California, have-invented new and useful Improvements in Sheet Material, of which the following is a specification.

This invention relates to a sheet material and particularly pertains to a sheet material `which isespeclally adapted for use in the manufacture of plant protectors, and the like.

It is the object of this invention to provide a sheet material as an article of manufacture which is non-absorptive, translucent and provided with air insulation, so that when formed-as a plant protector it will operate to exclude excessive moisture,v admit the necessary light, and protect the plants from injury by heat, cold or frost.

Another object is to provide a sheet material of the above character which is'iexible and whichv has a reinforcement incorporated therein by which the material is strengthened, and which will maintain the material in any shape into which it may be formed.

Another object is to provide a flexible and semi-rigid reinforcing member for the sheet material, which will not warp or twist the sheet during the process of manufacture but .which is pliable and adapted to be bent into and to'remain in will permit the sheet being smoothed or straightened into its normal substantially Hat condition after having been bent or .crumpled Another object is to provide a wire reinforcement for the sheet material which is so shaped that it may be securely attached Q to the sheet by an adhesive or cementitious substance.

A further object is tecting material which subject to breakage or easily damaged in handling, or excessively injured by contact with the soil, and that it canbe particularly and economically used in the propagation of vegetables and other plants having little initial value.

The invention is illustrated in the accompanying drawings in which;

Figure 1 is a plan view illustrating the sheet of material. Fig. 2 is a detail with portions broken away from a portion of the l5 sheet showing the manner of reinforcing the same. Fig. 3 is a'deta-il view inv section on to provide a plant pro- Specication of Letters Patent.

the line 3-3 of Fig. 2 showing the air insulating space formed in the sheet. Figs. 4, 5 and 6 are perspective views illustrating the sheet-as formed into plant protectors of "arlous shapes.

In carrying out the present invention the sheet 1s preferably formed of two layers, 7 and 8, of paper or similar material so treated as to be translucent and non-absorptive in character; the paper being of such quality and texture that it may be readily'bent into varlous shapes and folded upon itself without breaking.

Interposed between the paper layers 7 and 8 are reinforcing members 9 and 10 which are preferably arranged to extend laterally and longitudinally of the sheet as shown in Fig. 1. The reinforcing members 9 and 10 are here shown as formed of crimped or corrugated wire which is held in place between the layers 7 and 8 by means of adhesive or cementitious substance /11 of any suitable character but which is necessarily .iexible and non-absorbent. The reinforcing wires are arranged between the layers with their corrugations extending on the plane of the latter so that the finished material will be thin and also forming an irregular body which, on the sheets being adhered together, between the corrugations by the cementitious substance, will forml such an engagement as to prevent longitudinal displacement of the wires. This permits a sheet of material being cut into sections .without loosening the reinforcing wires. It is evident that the reinforcing members may be arranged in any manner in relation to each other but are here shownextending longitudinally and laterally across each other describing rectangular spaces 12, this arrangement facilitating manufacture. Substance 11 also serves to cement the two layers of paper together along the reinforcing members thereby dividing the space between the sheets into hermetically sealed compartments and thus yforming air insulating spaces.

By forming the reinforcing members 9 and of crimped wire, buckling or warping of the sheet in the process of manufacn#ture is V'obviatedand .by employing a wire of such character that it will normally remain in any shape in which it is bent the sheet may be smoothed orstraightenedl after havlio plant protectors.

l While thesheet constituting the present invention is applicable for various uses it is especially adapted to be employed in the construction of plant protectors and may be bent or folded into numerous shapes to provide plant protectors of various forms. For instance, the sheet may be folded upon itself at one edge and the ends of the transverse reinforcing member J connected together to form a substantially conical structure as shown in Fig. 4 which, if made of a rectangular sheet, will have projecting portions 13 on the enlarged end thereof which may be embedded in the soil to anchor the structure in position over the plant or seed to be protected. The sheet may also be bent 4to form a cylinder with its end portions connected together or connected to a stake 14 adapted to be driven into the soil to hold the cylinder in position around the plant. The upper end of the cylinder thus formed may be left open as shown or may be drawn together to exclude the light or frost.

In cases where long rows of seeds are planted the sheet may be arched thereover as shown in Fig. (3 with its edges held in place on the soil in any desired manner. It is manifest that various other forms and arrangements as well as other uses may be re-v sorted to.

By forming the sheets of layers of material which are translucent the necessary light may be supplied to the plant and at the same time prevent the plants from being injured by intense sun rays. rl`he non-absorbent character of the sheet renders it durable and protects the plant from eXces sive moisture during rain or in irrigating by sprinkling. By providing the sheet with air spaces the penetration of heat or cold through the-material is retarded. By providing the reinforcing members 9 and 10 the sheet may be bent and retained in various shapes which is facilitated by forming the reinforcing members of crimped Wire.

It Ais manifest, however, that other forms of reinforcing members may be employed .if desired. The use of aflexible cementpermits the `sheet being bent; and .'folded without injury of the cemented jointsand prevents breaking -ojfffthe sheet on sharp folds.

What I claim is: f

l. As an article of manufacture, a sheet material comprising a pair of fiexiblle layers7 a series of crossed semi-rigid reinforcing members interposed between said layers and affixed thereto, and a cementitious substance embedding theQ reinforcing members dividing the material into air insulated sections.

2. As an article of manufacture,rv a sheet materia] comprising a pair of flexible layers, a series of .rossed corrugated pliable reinforcing members interposed between said layers and arranged with .their corrugations extending on the plane of the layers, and means for fastening the reinforcing members in place serving to allix the flexible layers together and to form air insulated spaces extending between the reinforcing members.

3. As an article Aof manufacture, a sheet material comprising a pair of iexible layers, a series of intersecting corrugated pliable reinforcing members interposed betweenl said layers and arranged with their corrugations extending on the plane of the layers, and a pliable cementitious substance joining the layers along the corrugated reinforcing members forming the sheet into hermetically sealed compartn'ients.

4. As an article of manufacture, a sheet material comprising a pair of layers of flexible translucent and non-absorbing material, a series of intersecting pliable corrugated reinforcing members interposed between said layers and arranged with their corrugations extending on the plane of the layers, and a pliable eementitious substance joining the layers along the co-rrugated reinforcing members forming the sheet with hermetically sealed sections.

In testimony whereof I have signed my name to this specication.

EDMUN D A. GULICK.
