COPYHOLDER Filed May 31, 1930 2 Sheets-Sheet 2 Patented June 12, 1934 UNITED STATES PATENT OFFICE 6 Claims.
This invention relates to copy holders for typewriters and has as its principal object the provision of a device which may be adapted to hold various types of matter, of which some portions are to be copied. The principal object of the invention is to provide means by which material ranging froma single sheet of paper to a book of considerable size may be supported and shifted at will to display the copy as desired. A further 10. object of the invention is to provide a device which maybe folded across the top of a typewriter so that a cover may be placed over the holder and typewriter.
These and other objects will be more fully disclosed in the detailed description of the device shown in the accompanying drawings as an illustrative embodiment of the invention, and in which Figure 1 is a side elevation partly broken away; Fig. 2 an-elevation of the upper portion of the holder with the side casing and the upper operating knob removed; Fig. 3 is a front elevation with central portions broken away; Fig. 4 is a horizontal section on the line IV--IV of Fig. 1; Fig; 5 is a front elevation with the central and 25.;1ower portions broken away and with thebook holder in front elevation and attached in the lowermost position; Fig. 6 is a plan view of Fig. 5 below theline VIVI omitting the pressure rollers and showing the upper supporting section in elevation; Fig. 7 is a vertical section on the line VIIVII of the upper portion of the device in Fig. 5 with parts broken away and with the book holder in elevation in the lowermost position; Fig. 8 represents a typical form of clamp for attaching the suspension means to the roller; Fig.
9 shows the holder folded together, and Fig. 10 is a plan view on a smaller scale than that of Figs. 1 i
to 6 showing in broken lines the manner in which the parts may be swung upon their hinges.
40,; In the illustrative embodiment of the invention shown in the drawings, the main supporting member consists of two sections 1 and 2 pivotally connected by hinges 3, 3, permitting the section 1 to be folded upon the'section 2, the broken line showing in Fig. 1 indicating the member 1 as swung part way down and the showing in Fig. 9 indicating the section fully closed upon the section 2. A lower member 4 is hinged at 5 upon one side of the section 2, being shown folded against 50. the section 2 in Fig. 9 and in broken lines in Fig. 10. In normal use it extends at righ angles to section 2 as shown in Figs. 1 and 10, to form a wide base to hold the sections 1 and 2 in vertical position. Brace members 6, 6, may also be jhinged at the lower end of section 2 on the opposite side from the member 4, andwhen these are at right angles to the member 2 as shown in Fig. 10,- they act to prevent backward tilting of the supports 1 and 2. When not in use they fold against the section 2 as shown by the broken lines in Fig. 10.
A transverse roller 7 is mounted for rotation within the section 1 upon. a shaft 8, which is provided with a ratchet wheel 9 and an operating knob or handle 10. The ratchet wheel 9 has a.65 detent 11 pivoted upon the section 1 preferably within a closed casing and normally held in engagement with the ratchet wheel by a spring 12 which may also act to hold a pawl 13 in contact with the opposite side of the ratchet wheel. The pawl 13 is pivoted upon a bar 14 vertically movable within the casing and limited in its movement as by slot 15 and pin 16. A spring 17 acts to draw the bar 14 into its lowermost position. A bar 18, similar to the bar 14 is mounted in a closed casing in the lower section 2 and guided by limiting slot 19 and pin 20.
. Normally the lower end of bar 14 is held flush with the lower end of section 1 and the upper end of the bar 18 is held flush with the upper end of 0 section 2 and in line with the bar 14. Abell crank lever 21 pivoted within the base member 4 has a slotted end 22 engaging a pin 23 upon the bar-18'. The lever 21 is connected by a link 24 to a bell crank lever 25 which in'turn is con- 5 nected by a link 26 to a pivoted lever 27 having an adjustable knob 28 to regulate the amount of movement of the lever 27. A spring 29 normally holds the lever 27 in its uppermost position and the lever 21 with its slotted end in lowermost position where it will engage the pin 23 as the member 4 is swungfrom its folded position to its open or operative position. Downward pressure on the knob 28 will act to thrust the bar 18 and hence the bar 14 upward, which will cause the pawl 13 to rotate the ratchet wheel 9 and the roller 7 to which it' is attached. A transverse bar 30 preferably of non-circular section except at its extreme ends is journaled in the upper end of section 1. At one end of the bar is an operating knob 31 and at the same end a mutilated gear 32. Arms 33, slidable upon the bar 30 carry rollers 34 which are normally pressed toward the roller7 by the action of a spring 35 upon an arm 36 secured to the bar 30.
A transverse bar 37 journaled in section 1 near the roller 7-carries arms 38 which are connected by a cross bar or reading bar 39. At one end the bar 37 has an operating knob 40. One of the arms 38 has gear teeth 41 formed thereon adjacent to 2 the point of attachment to the shaft 37. Pivoted between the gear 32 and the gear teeth 41 is a mutilated gear 42 having an operating arm 43 normally held in inoperative position by any suitable means, not shown, with the smooth, untoothed portions of the gear located adjacent to the teeth upon the gear 32, and the teeth 41. With this arrangement, the arms 38 may be lifted freely by turning the knob 40, and the reading bar 39 will thus be lifted away'from the member 1. Similarly, the arms 33 maybe swung outward freely by turning the knob 31, to lift the rollers 34 off the roller 7.
Downward movement of the operating arm or lever 43 will cause the teeth 44 and 45 upon the mutilated gear 42 to move into engagement with the teeth 41 and the teeth upon the mutilated gear 32, the sizes being so proportioned that the reading bar 39 will be swung farther than the rollers 34 but both will be out of the way of any paper, booklet, or other relatively thin book from which matter is to be copied. When the lever 43 is released, the bar 39 andv rollers 34 will be lowered by the action of gravity and by the force of the spring 35 acting through the gears 32 and 42.:
As indicated in Fig. 2 in broken lines, the arms 33 may be swung backward to carry the rollers, 34
into inoperative position where theywill be held swing away from the copy simultaneously.
3. A device as in claim 2 in which the actuat ing device comprises a mutilated gear having.
by the action of the spring 35 upon the arm-36.
When a heavy book is to be held, an additional carrier is provided, consisting of a panel 46 having side flanges to engage within guides 47 upon the members 1 and 2, a pair of flexible bands 48 being secured to the panel near its lower end, and
j thence extending upwardly to a clamp 49 'whichmay be of spring steel toothed as indicated at 50. This clamp is sprung upon the roller '7 to which it clings with sufficient friction to cause the bands 48 to wind upon the roller '1 when the roller is rotated. The bands are preferably spread at the bottom more widely than at the top to cause the bands to wind spirally upon the roller to'prevent.
overlapping of successive turns. At the bottom of the panel 46 is a shelf 51 upon-which thelower j edge of a book may be placed, and at the top of the panel'are spring clips 52 carryingv rollers 53 which may be placed upon the pages of the bookto hold them in place.
The detent 11 and pawl 13 may be spread from eachother against the action of the spring 12 by a separator bar 54 mounted for rotation in the casing and having an operating knob 55. With the feed roller 7 freed from its pawl and-detent, any copy held upon the roller or mounted upon the book carrier panel may be moved up or down' to any position desired by'rotation of the knob 10, whereupon the detent 11 may be released again to act upon the ratchet 9.
As indicated by broken lines in Fig. 10, the copy holder will normally be set in the rear of a typewriter 56 with the hinged base section 4: at the right handside of the typewriter where the knob or key 28 will be in position beside the usual shift key 57, convenient for the operator to press v at will.
I claim:
1. A typewriter copyholder comprising upper and lower sections pivotally connected together to fold substantially parallel with each other, and a base section pivotally connected to the lower section to fold upon the lower section beneath the folded upper section, a feed roller and an actuating means for the said roller mounted on the upper" section, an operating member mounted on the base section, and an element mounted on the said lower section adapted to be engaged by the said member and to engage the actuating means for the feed roller when the sections are unfolded into operative position, whereby to transmit movement from the operating'member to the feed roller, to actuate the portions of the mutilated gear in position to be.
engaged by teeth upon the mutilated gear. when the gearis rotated.
