Fig. 2 is a section on line m2, Fig. 1.

Fig. 3 is a perspective View of the skeleton frame employed in construction of desk shown in Fig. 1.

Fig. 4 is an elevation of an artificial arm formed of my fiber wood structure, parts being in section to show the arm socket at the shoulder, and-the joint connection at wrist and elbow. Pulps as heretofore employed, have been compounded usually for a specific purpose Fig. 5 is an v,enlargement of the hand shown in Fig. 41' with wrist and lower forearm in section to show detailed construction and joining of parte.

Fig. 6 is a slde'elevation of an artificial foot and lower limb, formed with my fiber wood construction, partly in section; different positions of foot being shown by dotted lines.

Fig. 7 is a section on line m7, Fig. 6.

Fig. 8 is a front elevation of an artistic mirror frame formed of my artificial fiber Fig. 9 is a section on line ai", Fig. 8.

Fig. 10 is a front View of a tile or decorating plate formed of my artificial fiber wood structure.

Fig. 11 is a section on line Fig. 10.

Fig. 12 is an axial section through a bath tub formed of my artificial' fiber wood structure.

Fig. 13 is an axial section through a leg for furniturev construction composed principally of'my artificial wood and showing a reinforced center staff therein and a caster attached to the staff.

In preparing the composition I prefer to use the ingredients in about the following proportions, the parts being given by weight as follows: viz: fifty-six pounds of fiber pulp, thirty-four 'pounds of magnesite and ten pounds of asbestos mixed with liquid magnesia chloride 22o Baume to a consistency adapted to fulfill requirement-t to pour or to make a paste or dough to be molded.

Good results may be obtained, however, when the ingredients are varied within' the following limits: fifty to sixty pounds of fiber pulp, thirty to forty pounds of magnesite and five to fifteen pounds' of asbestos l Baume to requirement to pour, or to form a paste ordough to be molded.

I obtain my ber pulp from any fibrous material, such as waste wood or lumber, saw dust, paper, straw, leaves, cane or corn stalks, properly disintegrated. This ber I combine with t-he other ingredients as before stated and mix to requirements.

When my articial ber wood is to be used in the construction of furniture or other things requiring' a metal or wood frame supporft as shown in Figs. 1, 2, 3, 13, I make the wooden supports re proof by painting them with a' non-combustible paint before moulding, pasting or pouring my articial ber wood around the frames.

I prepare this re proof paint by mixing the composing ingredients in about the following proportions` viz: forty parts lime, twelve and one-half parts cooking salt, f* teen parts alum, and thirty-two and onehalf partsv Wolframate of sodium or sodium tungstate.

This fire proof paint I apply to the wood reinforcement or fra-me of urniture and after it dries I apply my artilicial ber wood by pouring into prepared form or dies, pasting it on, or by hand modeling the doughy mass into a desired form.

In constructing furniture, as for instance, the desk 1 shown; in Figs. 1, 2, 3, various molds, not shown, are used toenclose the frame 2, after which the pulp is applied to fill the molds and form the desk with drawer enclosures 3.

Drawers 1 1. are provided that have wood reinforcements 5 that are made re proof.I by application of my paint as applied tol frame 2.

- Legs 6 of frame 2 if desired can be provided With roller casters 7 so as to support the desk 1 clear of the floor.

When my artificial 'ber wood is used in the construction of artificial limbs it is preferably mixed to a dough that can be modeled into a desired size and form to suit the individual for whom it'is constructed; and a esh color added to the dough corresponding to the natural color of the proposed wearer.

When a full arm 8 is formed as shown in Fig. 4, the upper arm is provided at the shoulder with a socket 9 that can be formed to fit the stub end of the wearers arm. At the elbow and wrist, arm 8 is provided with ball and socket joints 10, 11 that permit a limited natural movement or swing of the joined parts.

In constructing joints 10, 11, the ball portions 10, are formed first and after they have hardened they are polished to give them a smooth nish. Then the balls are immersed in melted paraiin which when cooled forms a thin coat 12 over the balls. Then the socket ends 11 of the arm are formed over the balls; and, after the .socket ends have hardened the paraHn is subjected to heat and permitted to escape from the joints, after which lubricating oil is injected to facilitate a free movement of parts. By this construction inseparable joints are formed which connection of parts can. be made by the artist modeler to assume the graceful swing or movement of a natural arm.

A different form of joint is shown in Figs. 6, 7 in which a steel ball 13 and socket '111 are interposed between the foot and leg l5, 16.

A clearance is left between the foot and lower limb so that there is a limited movement of the foot on ball 14. The lower end of the limb 16 has inclined sides 17 that correspond to similar inclined sides 18 on the foot 15 and these slides in contacting limit the side movement of the foot relative to the limb; that is the foot'has a slight side movement so that it can assume a flat contact when the wearer is travelling over uneven ground.

When my artificial fiber wood is used in molding or modeling picture or `mirror frames the pulpy can be colored to obtain various artist-ic effects. As seen in Figs. 8, 9 the frame 19 has four shades 20, 21, 22, 23 which can be of diiferent colors or if desired can be different shades of a single color that is mixed with the dough before the frame is formed.V

The frame can be open for a picture, not

shown, or it can be provided with a mirror 24 that has its ed es embedded in the dough; and the back of t e mirror and frame can be strengthened by cardboard, or by canvas or board backing 25 cemented thereto. Y When my artificial ber wood is to be used in exterior andinterior decoration the tile or plates can be formed in thin sheets 26 which can be placed on a designing table convenient for the artist to engrave or emboss or imprint any desired design thereon, after which the sheets or tile can be secured in place by plastic means.` The sheets can have a backino 27 of paper, cheap cloth or Wire.

Ihen my artificial ber wood is used in making toilet ap-pliances such'as a bath tub 28, it is molded into the desired-shape and then the entire surface is subjected to polishing. If desired, the inlet water pipe 29, outlet pipe 30 and over-flow pipe 31 can be molded into the wall of the tub leaving the necessary pipe ends extending for pipe and fixture connections.

My artificial ber wood is especiallyadapted to the construction of furniture fixtures requiring great artistic skill in modeling and embossing thereon desired decorative e''ects, as it/ can be reduced to the right pliableness to be molded into any desired form and retain that shape without cracking,A

sagging or excessive shrinking..

As seen in Fig. 13 the furniture leg 32 is formed around a straight upright wood support 33 that is made fire proof as previously stated. rlhe leg 32 has an elongated forward extension ,34: unsupported by anything but the tenacity of the iibrous composition, also the back portion of the leg 32 has the enlargements 35, 36 that are formed without sagging, (owing to the disposition of the composition to retain its shape when unefi'ected by modeling-force.

In operation my artiicial fiber wood is prepared as. previously stated to pour, plaster or mold, after which it is used by the artist or modeler to express his artistic ideas.
