This invention relates to a copy-holder for typewriting machines and consists essentially V in connecting the copy-supporting plate adustably to a curved supporting arm com- '5 posed of parallel, channelled, inter-connected above the typewriting machine and turned back when not in use.

Being composed of channelled members, the supporting arm can be made light and yet very steady, which is essential for a good copy-holder. I

It should be observed that'pivotally arranged copy-holders are known per se.

The copy-holder consists of a copy-supporting plate 9 and a curved supporting arm or bracket 4 which latter holds the plate in a suitably-inclined position. The bracket is at- :tached to the typewriter table so that it can hold the plate 9 overthe platen of the machine, right in front of the operator. Thus the'copy as well. as the machine can be readily -watched at the same time. The bracket 4 is 7 held bya pivot pin 3 on a

screw clamp

1 or 50 the like whereby the copy-holder is connected the clamp l. ;The bracket members are situ- .ated at oppositesides of the lug, and to ob-' The pivotal deflection of the bracket is limto the top of the typewriter table. The arrangementis such thatthe bracket can be adjustedforbringing the plate more or less to the front and also for turning it right back so as to give free access to, themachine for the insertionand removal of the paper or for other operations. This latter. feature is known per se.

According to the invention the supporting arm or bracket 4 of thejcop'y-holder is comno posed of two parallel members 4a and 4b which are inter-connected and distanced by

stays

28, 29 and 30. Theinembers are made of metal plate andchannelled, as shown in Fig. 2, to give the necessary strength and rigidity. A web 31 co'nnectsthe two members at one end and carries the copy-supporting plate 9. The latter is fitted with two parallel v .

rails

32 and 33 between which the web 31 is slidably guided'so that the plate can'be adjusted to different positionsand alsoentirely removed from the bracket. The guide rails are composed of metal strips which are formed along the inner sides with offset portions under which the web 31 engages. The

metal strips forming the guide rails 32and 33 are also extended and beaded so as to form sleeves in which the ends of a wire shackle 34 are telescopically guided. The shackle 34 serves, when extended, as a support for large no copy sheets, and it carriesa clip 35 to which the sheets may be connected.

The pivot pin 3 of the bracket is secured by means of a grub screw 36 to alug 20!. on

tain a steady and yet easy joint without careful fitting, resilient washers 37 areintroduced between the lug and the bracket members.

against the lug 2a and against the screw head. The plate 9 may be fitted with a line indicator 21.

In cases where a particularly steady copyholder is required, the construction shown in Figs. 49 may be resorted to. In this construction the bracket is composed of two

parallel members

40 and 4d which are held by

stays

46, 47 and 48 at a considerable distance apart, each member being pivoted to a separate lug 27) mounted on a base plate 49 whereby the holder is secured to the top of the typewriter table. Each member is composed of two channelled metal strips which in this case are oined together as best shown in Figs. 12 and 13 so as to form a square tube having rounded corners. The tubes are forked for enga ement with the lugs 27), and springs 37 are introduced between the forks and the lugs so as to obviate careful fitting. The upper stay 46 consists in a plate having a centrallydisposed guide strip 50 the edges of which are offset for engagement with the beaded edges of the corresponding guide strip 51 connected tothe back of the copy-supporting plate 9. An eccentric disc operated by a hand lever 52, is fitted at the back of the stay 46 for clamping the plate 9 to the stay in different positions of adjustment. The lower edge 53 of the plate 9, which is upturned for supporting the copy, is strengthened by two angle pieces 54 and by an additional strip 55 between which and the parts 53 slots 56 are formed for the reception of the supporting arms of a lamp fitting 25. The strip 55 is slit at 57 so as to form resilient tongues for engagement with the lamp-supporting arms.

The stay 48 co-operates with a stop 58 for limiting the movement of the holder about the pivots 8. A screw 59, which is braked by a spring 60, is fitted at one side of the stop for regulating the normal position of the holder.

The tubular form of bracket may also be employed where only one arm is used, as shown in Figs. 10 and 11. The metal channels may be stamped with clips 15 for the support of the lamp wire. The arm is forked at both ends and flanged at the upper end for the reception of a plate 50 for engagement with the guide strip 51 of the copy-supporting plate.
