Fig. 1 shows one form of copy holder particularly designed for use upon an Elliott Fisher typewriting and accounting machine and Figs. `2, 3 and 4 show a slightly different form conprises a rectangular platen frame having spaced parallel sidey bars lor rails indicated at 2 connected by cross bars, one of which is indicated at 4, and a flat platen indicated at 6 mounted for vertical movement in said frame. Upon the rails 2 of the platen frame is mounted for forward and rearward movement a line space frame 8 having front and rear rails lll and I2 upon which is supported for letter spacing and return movement a type carriage I4.
The parts above briey to have substantially the same construction, arrangement and mode of operation as the corresponding parts of the machines illustrated and described in said patent and application.
The present machine is provided with a casing for enclosing certain portions of the line space frame. The casing comprises two hollow end members I6 and I8 arranged to enclose certain parts v"at the opposite ends of the line space frame. These end members respectively are detachably mounted on the side members 20 and 22 of the line space frame. The casing member I6 is detachably secured by suitable screws to an extension 24 on a plate 26 fixed at its forward end to the upright bracket 28 rigidly attached to the rear-rail l2 of theyline space frame. To this rail is also xed a bracket 30 a'nd the casing member I6 is provided with a projection or lug 32 which is screwed or bolted to the under .side of the bracket 3U;
The casing member I8- is detachably xed by secured to the line space frame between said arms and enclosing the portion of the line space frame between said rst two casing members.

5 Claims. (Cl. 242-45) The present invention relates to handling filaments. More particularly it relates to handling elastic filaments and to the feeding of such filaments to using operations under substantially uniform tension. 'I'he preferred embodiments of the invention comprise a process and apparatus for handling elastic filaments which may be formed of uncovered rubber-like materials or rubber-like materials provided with' any desired type of covering. A
The majority of using operations for elastic filaments, both bare and covered, require that the filament be delivered to the using operation in a condition of substantially uniform tension. This has been the cause of considerable difficulty heretofore because of the fact that the elastic nature of such filaments makes it diicult to handle and transport the filaments without creating uneven tensions throughout the length of.
the filament. For example, it is essential from a practical standpoint that such elastic filaments be formed into some kind of winding to make it possible to handleand transport the filaments and also to feed them to using operations. One of the most common types of packages into which such filaments are wound for transporting, handling and feeding to using operations comprises a spool upon which the filament is wound. Regardless of how much care is exercised in initially winding th'e elastic filament upon the spool, the elastic illament willbe subjected to varying tensions when removing it from the spool since the elastic nature of the filament causes the convolutions of the filament to crowd together and thereby embed some of the convolutions beneath others. When the embedded convolutions are reached during removal of the filament from the.
'increase in tension is, of course, carried into the using operation and thereby causes the finished article to be nonuniform in character. The existence of even slight tension variations along the length of an elastic filament fed to a using operation, such as a knitting operation, causes the knitted product to be puckered over certain areas and unsightlyas well as unfit for satisfactory service.
It is an object of the present invention to provide a process of feeding elastic filaments to a using operation under a substantially uniform tension.
It is another object of the present invention to provide a process of unwinding elastic filaments without creating excessive tension variations along the length of the elastic filament.
' It is also an object of the present invention to provide an apparatus for feeding elastic filaments to a using operation under substantially uniform tension,
It is a further object of the present invention to provide an apparatus for unwinding yelastic filaments without creating uneven tension along the length of the elastic filament.
Other objects and advantages, if not specifically pointed out, will be apparent to those skilled in the art from the following detailed description of what are now considered the preferred embodiments of the invention.
The process of the invention in general comprises rotatably supporting a supply winding of elastic filament, rotating the supply winding by frictionally contacting the surface thereof by a member rotating in a direction to remove filament from the winding, the frictional contact preferably taking place substantially at the point where the elastic filament leaves the winding, 1 applying tension to the elastic filament at a point frictional contact with the surface of the winding, and means for frictionally contacting the unwound elastic filament at a point close to the supply winding and over a considerable area. of the filament to apply tension to the filament.
The invention accordingly comprises the several steps and the relation of one or more such steps with respect to each of the others, and the apparatus embodying features of construction, lcombinations .of elements and arrangement of parts which are adapted to effect such' steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention reference should be had to the `following detailed description taken in connection with the accompanying drawing, in which:
