PAPER SPECIFICATION formingpart of Letters PIPNG,
Patent No. 291,572, datcd Januaiy 1, 1884.
Application tiled September 18,1583, (No model.)
To @7l wiz/0m it may] core/cern:
Be it known that I. JOHN MoCAUsLAND, a citizen of the United States, residing at Providence, in the county of Providence. in the State of Rhode Island, have invented anew and useful Paper Piping, ot' which the following is a specification.
My invention relates to a pipe made of paper, paper-pulp, and paper-pulp and textile fabric interlaid, and the lengths thereofjointed by couplings ofthe same material.
The object of my invention is to provide a. cheap, practicable, and serviceable substitute for metallic pipes.
I desigato use my invention more particularly for speaking-tubes, and air and water conductors.
In the drawings, Figurel represents aspeaking tube constructed of paper. Fig. 2 is a longitudinal section,sliowingthe uiode of coupling two lengths of pipe together. Fig. 3 is aseetional end View, showing theinauner of interlaying the paper and textile fabric.
A represents the straight lengths of pipe, which are made of paper, or paper-pulp, or paper-pulp and textile fabric interlaid. The lengths are connected together by couplings c, made of the same material or materials as the pipe, and shrunk onto the ends of the pipelengths. The elbow-joints E are made of metal, rubber, or other suitable material.
S represents the mouthpiece of a speaking tube.
c represents the pulp or paper, and Z1 the textile fabric.
I have found that interlaying the paper or pulp with some textile fabric strengthens the pipe materially, that it cannot be broken, and that it is more impervious to water or dampness. I form the pipe of paper or pulp on a cylindrical former, and if it is to be used as a water-conductor I shellac or japan it on the outside and inside.
The great disadvantage, aside from the cost, in the use of metallic speaking-tubes arises from the reverberation. which renders the tone indistinet and confused in speaking through tubes of any' considerable length, or having many turns in them.
In practical operation it has been proved that pipes constructed after my invention, of paper or interlaid textile fabric and paper, do not deaden the sound, and thatthere is no reverberation, the tone coming clear and distinct at all times.
I claim as my invention and desire to secure by Letters Patent-- l. A pipe for speaking-tubes and other purposes, constructed of paper tubes A,connected together by elbows E, of metal, rubber, or other suitable material, and paper couplings c', as shown and described. 2. A pipe for speaking-tubes, and air and i water conductors, constructed ofalternated layers of paper a and textile fabric b, as shown l and described.
