Application filed February 8, 1910, Serial no.
To all whom it may concern:
-Be it known that I, WiLLrAM JOHN SMITH, a citizen of the United States, and a resident of the city and State of'New York,
" have invented certain new and useful Imwhich is placed the paper upon which the -.provements Platens, fication a My invention relates: to the roller or platen of a typewriting machine, upon in Type-VVriter Rollers or writing isto be produced by the type of the machine, the. object of the invention being to i produce ,a roller or platen which shall be -tica1 section of-the same,
strong, durable and otherwise efiicient, and at the same time more'nearly noiseless-than the rollers or platens now in use. r The invention consists in the novel con- 4 struction, arrangement and combination. of efalenifnts hereinafter more particularly set ort is a longitudinal vertlcal section. of a type- Writer roller or platen constructed according to my. invention, Fig. 2 is a transverse ver- Fig. 3 is a perspective view of'ja portion of the invention, which is hereinafter more particularly described, andFig. 4. is a view of a modification of the invention, as hereinafter de- 1 scribed.
other v yielding or porous nature, adapted to abf In carrying my invention into effect, 'I provide a tube or sleeve .A, of rubber or other suitablematerial of any 'desired'de- 'gree of hardness, which serves as the outer 'vide an inner tube or sleeve B, of feltor suitable material of a somewhat soft,
sorb the vibrations produced-by the operationof the typewriter, and thereby minimize the noise'accompanying'the same. Be-
' v tweenthe outertube A and the inner tube B .is, placed a. tube or sleeve C, preferably of sheet metal or other similar-material.
The tube or sleeve C is-provided with a number of perforations or openings D, Lwhichare'produced by a solid punch or in somekotherysuitablemanner-so as to not make clean-cut edges, but rather to make 1 rough or ragged depressed edges,
- burs on the inner surface of the tube C, as
forming sliownatEL v Inside-of-the innertube 'B,'-I"-provide means for holding out in position the com paratively soft andyielding material of the Specification of Letters Patent.

. said tube B, and :pressing-thesame firmly against the tube C and into engagement with the burs on the inner surface thereof. Suchholding means mayconsist of rings of spring sheetqnetal, as at F, 'orsplit rings of; elastic wire, as at G, or anyother equivalent means.
Each end of the platen is provided with a disk H, having bearings I, or similar dc vices, for the purpose of mount ng the platen and allowing it torotate, or the same may be rotatably mounted in any suitable manner. I do not limit myself to theeract details of construction herein described, nor to the particular materials specified. as it is obvious that other equivalent materials may be 0111-:
ployed and. that considerable variation in the details of the construction may be permitted, Without departing from the spirit and scope of myinvention. As one instance of such variation I Wlll mentlon that the sleeve C may be provided with a series of slits-or lengthened perforations, either alone and in substitution for, or'associated with, the smaller and approximately,cu-r'ular porforatlons already described, but
tending edges or burs, so as to efficiently engage with the material of the inner tube This modificatlon is shown in Fig. 4.
ln the operation ofmy invention the always pro- Y vided with the roughened and inwardly exinner tube B of felt or other suitable soft and vibralion-absorbent material is kept pressed up closely against the inner surface of the sleeve C, and the burs E are therefore forced into the soft material B and engage therewith. ()n this account all vibrations produced in the roller by the impact of the type thereupon or otherwise are effectually damped and absorbed .and all undue noise prevented. 'I- have found in practice that a typewriter equipped with a roller or platen constructed according to my invention'is far less noisy than a machine provided with the ordinarytype of roller or.
platen, such sound as is made proceeding in such case; from parts of themechanism other than thetyp' and-the roller. At the same time, the resistance of the roller to the stroke of the type is amply suliicient to'produce a clear of'sheets of paper, with'carbon sheets interand sharp mpression upon the paper placed-upon the roller, even where a number posed, are employed, for the purpose of producing carbon copies.
I am aware that it is already known in the-art to construct atypewriter roller or 1. A roller orplaten for typewriting ma" chines, comprising an outer impact layer or surface, an inner layer of vibration-absorb ing and sound-mufliing material, and an intermediate layer of material adapted to sup port and strengthen said outer layer, the said intermediate layer being provided with perforations having inwardly projecting edges forming burs adapted to engage with the material of the said inner layer.
2. A roller-or platen for typewriting machines, comprisin an outer impact layer or surface, an inner ayer of vibration-absorbing and sound-muftling material, anintermediate layer of material adapted to support and strengthen said outer layer, provided with perforations having inwardly projecting edges having burs adapted toengage with the material ofthe said. inner layer,
and means for securing the said inner layer in position firmly against the inner'surface of the intermediate layer and in engagement with the said burs thereof.
3. A roller or platen for typewriting machines, comprising an outer impact layer or surface, an inner layer of vibration-absorbng and sound-muilhng materlal, an 1ntermediate layerof material adapted to strengthen said outer layer provided with perforations having inwardly projecting edges forming burs adapted to engage with the material of said inner layer, and elastic means adapted to press said inner layer of an inner layer of vibration-absorbing and sound-mutlling material, and an intermediate layer provided with perforations Having inwardly projecting edges or burs engaging with sald 1nner layer.
5. In a typewriter roller or platen, the combination with an outer impact layer, of
an innerlayer of vibration-absorbing and sou'nd-mufihng material, and an intermediate layer provided with perforations or slits having inwardly projecting edges or burs engaging with said inner layer.
6. In a typewriter roller 0r platen, the combination with an enter impact layer. of an inner layer of vibmtion-absorbing and sound-mufiling material, an intermediate layer provided with perforations having inwardly project-ingedges or burs engaging with the said inner layer, and means for holding said inner layer in close proximlty to said intermediate layer and in cngagement witlrsaid burs, said means consisting of a circular spring inside of the inner layer. In witness whereof I have hereunto signed my name this 7th day of February 1910, in the presence of two subscribing witnesses.
