Tdatl concern: Bejit known that Nms H. Aivnnnson,"citizenjof.. -the. United States, and resident of Middletown, in the county of Middlesex and" State of Connecticut, has invented certain new and useful Improvements in Type- Writer Platens, of which the following is 'a specification q I. u My invention relatesto typewriter platens ittolls such as are employed upon writing or tubes somefofwhich have been filled'with so called deadening material, while .others.
have been provided with layersof felt, rubber, etc. All of these 'difier in principle from my inventionv and which as will be noted is made very largely of metal disks or units with. suitable layers of insulating materials therebetween.
Referring in detail to the accompanying diawings forming a partof this specification similar characters of reference will be found to designate like or correspondmg parts throughout the several figures and of which,
Figure 1 shows a side perspective view of a typewriter platen formed in accordance with my invention.
Fig. 2 is a sectional elevation of one end of the platen shown in Fig. 1.
Fig. 3 is a side elevation of one of the metal disks or units of which my platen 1S formed. Fig. 4. is a detached central vertical section through one of the metal and two of the 50 insulating disks, of which my improved platen is formed. Fig; 5 is a similar elevation of one of the insulating disks used between the metal units. 55 As before my platen includes rrrn-wnrrnnirhatrnn. i
Specification of Letters Patent. Patented Au'g; 1917. Application fileana a, 1914. Seria1No.S8 7 ,162.
an inner roll which in general external appearance looks very much like that of an ordinary wooden roll such as is commonly used in typewriter platens. My roll, how ever, is formed very different and largely of .66 metal, but like the wooden rolls before mentioned is provided with a relatively hard rubber coveringthat I have designated as 10 and which forms. the striking pad for'the typewriter bars. I i
The inner'or body portion of the roll is bu lt up of a series of comparatively thin metal disks or units 11 which are preferably substantially like that shown in Figs. 3 and 4 said disks being preferably stamped up from sheet metal and include a bridge or spokemember 12 and aseries'of holes 13.
The said holes serve to accommo date'the tie rods 14 later to be referred to and of which there are preferably three.- These disks are arranged vertically andin alinement, but are insulated one from the other by means of a thin sheet of relatively soft material 15 as for instance felt, paper .fiber or other deadening material. In fact I find insome instances it is quite practical to simply plate or coat the metal d1sks with a covering of soft insulating material as for instance rubber or e1iame1,'in' the manner indicated in Fig. 4:, the object being to so far as possible, separate the disks one from the other so that each disk or short series will serve to receive the blows of the respective types and in a manner to muliie or retard the sound produced by such contact of the type with the roll.
The object ofthe spokemember whichIhave preferably shown as a single cross or bridge piece is to further reduce the noise in that it extends across through the hollow portion of the roll and absorbs and retards the travel of the sound. In assemblin the disks I preferably arrange. these spo es in triple alinement, that is to say every third one alines with the next succeeding third one in 160 the series.
The insulating disks referred to are referably cut in a shape similar to that o the metal disks and like them are rovided with holes through which the binding rods pass. A suitable number of these metal and felt disks are assembled and arranged side b side in the ma'nner indicated to form a ho low roll of the desired length whereupon the ends are covered with endcaps 16 which 119 include hubs 17 and centrally drilled holes 18 in which the pintle ends 19 are secured. A single one ofthese caps is employed'to form the respective ends of the rolls and is provided with orifices to receive the bind ing rods 14 extended through the rollin a way to secure the parts in position and together. The rods are provided each with a screw head 20 on one end that is seated in a countersink of the orifice in the face of one cap and are threadedupon their other ends to engage threaded holes 21 in the cap 16 of the opposite end. When these disks and end'caps are assembled in the manner shown thev obviousl form what appears to be a solid rollinc uding a solid smooth peripheral surface, but which as a matter of fact is hollow inside. The hard rubber covering is adjusted and secured upon the roll to form the complete platen after the roll is made up and secured together by the rods.
Having thus described my invention what I claim and desire to secure by Letters Patent'is:
1. A noiseless platen for a typewriting machine consisting of an outer cylinder a laminated skeleton core with a continuous outer surface within and reinforcing the I walls of-the cylinder, heads at the ends of the cylinder, and means securing the heads and core laminae together.
2. A noiseless platen for a typewriting machine consisting of. an outer cylinder, a laminated metallic core within and'reinforcing the. walls of the cylinder, heads at the ends of the cylinder, and means securing the heads and core laminae together.
3. A noiseless platen for a typewriting machine consisting of a cylindrical covering having a continuous outer working surface, a laminated core formed of metal disks within and backing the covering, heads at the ands or said core. and means exte iding messes through the core and heads for holding the parts together.
4. A 'noiseless'platen for a typewriting 5. A noiseless platen for a typewriting machine consisting of a cylindrical covering havin a continuous outer working surface," a laminated core formed of metal disks and interposed sound deadening material withi in and backing the covering, heads at the ends of said core, and means extending through the core and heads for holding the parts together.
6. A noiseless platen for a ty ewriting machine consistin of an integral exterior cylinder formed 0 hard rubber, a laminated interior cylinder composed of metallic and sound absorbing disks, heads at the ends of thecylinders, and means securing the heads and the laminae of the interior cylinder together;
7. A noiseless platen for a typewriting machine consisting of an integra exterior c linder formed of hardened plastic material, a laminated interior cylinder formed of a series of closely packed perforated disks, heads at the ends of the cylinders, and
means securing the heads and the laminated disks together.
