Referring now particularly to Fig. 1, 15 represents generally a standard typewriter having supporting rear and front feet 16 and 17. The paper on which the typing operation is to be performed is carried on its Work roller 18. According to the present invention, the line copyhc-lder comprises generally a feed roller mechanism 19 which is mounted above the top front portion of the typewriter in front of the work roller 18 and supported by upstanding bracket members 20 and 21 that are connected to angle shaped base members 22 and 23 respectively that are held in place under the typewriter by the front feet 17 and further adjustable members 24 and 25 that are respectively connected to the members 22 and 23 and which extend forwardly to the front lower edge of the typewriter and a manual actuator 26 connected to the forward ends of the adjustable members 24 and 25. To operate the roller mechanism a press button 27 ofthe actuator 26 is depressed so that a flexible Wire 50 is extended through a flexible conduit 28 that leads from the actuator 26 tothe roller mechanism 19 to effect movement of a ratchet device 29 of the roller mechanism 19 and cause the step-by-step rotation of the roller mechanism and of the paper copy which the operator of members 32 and 33. Two rollers 34 and 35 laterally spaced from one another are iournalled in the end members 32 and 33.

3 These rollers have hand knobs 36 and 37 on their ends so that the user of the line copyholder can advance the paper by hand or can use the hand knobs to adjust the rollers for effecting the connection of the ends of the paper upon the roller mechanism.

Laterally or horizontally spaced from the end members 32 and 33 and from one another are two paper retaining members 38 and 39. Thesernembers, as shown in Fig. 3, are formed of spring strap and are secured to the bottom pan 31 by rivets 4-0. The end of each spring strap is rolled upwardly and bent upon itself to provide a paper retaining and guide portion 41 that partially surrounds the roller and which carries a small engaging roller 42 that bears against the surface of the adjustable roller to catch and retain the ends of a paper sheet 43 as illustrated in Fig. 3 and to cause the roller to take the paper sheet into the roller mechanism.

Mounted in the end member 33 is the rack device or mechanism 29, Fig. 2. The end member 33 carries on its inner side a guide bracket 45 that is secured by a rivet 46 to the end member 33, Figs. 2 and 6. This bracket supports and guides a rack 47 that has teeth 47' which engages with teeth 48 on drive roller 35. The rack 37 has an upstanding arm 49 to which flexible wire 50 extending through conduit 28 is secured by a set screw 51. The conduit 28 is secured to a post 52 on the end member 33 by a set screw 53. As the wire 50 is extended from the conduit 28, the rack 47 is advanced and the roller 34 is turned through the connection of the rack teeth 47' with the teeth 48 on the roller 35. A return spring 54 is connected between the rack 47 and anchor bracket 55 on the bottom pan 31, as shown in Fig. 2. The rack teeth 48 are connected to a hub portion 56 that is secured to the roller 35 by a set screw 57 and in particular to its rod 35, Fig. 5.

The upper part of the end member 33 has an elongated slot 33' in which the upwardly extending arm 49 of the rack 47 may operate or travel, Figs. 1 and 5.

Pivoted upon the rod 35' of the roller 35 adjacent respectively to the end members 32 and 33 are representa tive pivot arms 59, only one being shown, Fig. 1. Journalled and pivotally connected to the outer ends of the arms 59 are pivot brackets 61 secured by a pivot pin 62 and a cotter 63 that carry a transparent line guide bar 64 that will run under the lines as they are copied. The guide bar 64 and the arms 59 can be lifted back toward the typewriter work roll 18 at times when the paper 43 is being secured to the roller mechanism 19. When in use, the bar is dropped down upon the roller 34.

Illustration is made of the movement of the transverse guide bar 64 in Fig. 4 to show that it can be moved to different dotted line positions.

On the underface of the bottom pan 31 is a guide member 65 that receives a supporting bar 66 which is longer than the pan and which has its ends extending outwardly from the respective end members 32 and 33 of the roller mechanism, and to which hinge members 67 and 68 are hingeably connected respectively thereto. These hinge members depend downwardly along the side of the typewriter, and to them there are connected by fastening bolt means 69 and 70 respectively upstanding bracket members 20 and 21.

Each angle base member 22 and 23 is located under the front feet 17 of the typewriter. These angle base members 22 and 2.3 respectively have upturned portions 71 and 72 by which the respective bracket members 20 and 21 are connected to the base members in an adjustable manner by the provision of elongated slots 73 and 74' in the respective members 20 and 21 through which respective bolt fastening means 75 and 76 extend. Two transversely extending portions 22' and 23' of the respective angle support members 22 and 23 are respectively connected to the swingable arms 24 and 25 in an adjustable manner by the provision of elongated slots 4 77 and 78 in the respective arms 24 and 25 and fastening bolt means 79 and 80.

On the underside of the manual actuator 26 are swivel guides 81 and 82 which respectively receive the forward ends of the members 24 and 25. The actuator can accordingly be positioned at the center of the forward edge of the typewriter and held rigid by the tightening of the members 24 and 25 on their respective base members 22 and 23.

When the copyholder is placed on the table to the i right or to the left of the typewriter and stood up independently thereof, the actuator 26 may be fixed to the front of the typewriter by any suitable connecting means.

The actuator 26 comprises a casing 84 having a top portion 35 from which the press button 27 extends. The press button 27 has a vertical rack rod 86 that is supported in a guide bracket 87 attached to the casing 84 by screws 88, Figs. 7 and 8. This vertical rack rod 86 operates upon gear 89 to turn its shaft 90 and a large gear 91 thereon that meshes with a horizontally extending rack rod 92 that is slidable in a supporting bracket 93 and to one end of which there is fixed the end of the wire 50 by means of a set screw 94. The brackets 87 and 93 are respectively supported upon a transversely extending partition 95 in the casing 84. The bracket 93 is fixed to the side of the partition by screws 93'.

The conduit 28 through which the wire 50 slides is fixed within the casing 84 by a set screw 95 in a block 96 that is fixed to the inner side of the casing 84 by fastening screws 97 and 98, Fig. 8.

In order to alter the length of stroke of the press button 27 and the amount of movement of paper through the roller mechanism, there is provided an adjustable shaft 100 that is journalled in the ends of the casing 84 and can be turned by knobs 101 and 102 at the opposite ends of the actuator. This rod has opposite threads 103 and 104 and representatively adjustable upon these threads are blocks 105 and 106 to which links 107 and 108 are respectively connected. Surrounding the rack rod 86 and connected to the links of the links 107 and 108 is a stop member 109 which can be adjusted up or down to provide a stop against which the press button 27 will engage and to limit the length of stroke or downward movement of the press button whereby to alter the amount of movement of the paper in the roller mechanism. The links 107 and 108 are respectively pivotally connected to the ends of the stop member 109 to permit this adjustment thereof.

Referring now particularly to Figs. 9 and 10, there is shown a modified form of roller to be used in the roller mechanism and more particularly to the means for retaining the ends of the paper copy. A roller 111 would be provided with a central pivot shaft 112. The roller is preferably formed of rubber but is cut away at two 10- cations to provide a recess 113 for receiving a spring strip 114 of arcuate shape and which is fixed in the recess by fastening screws 115 that extend into the roller 111. To the free end of the arcuate spring members 114 is fixed by rivets 117 and inverted curved finger plate 116 of metal or plastic. The finger plate 116 can be elevated and the edge of the paper sheet 43 can be inserted thereunder in the manner as illustrated in Fig. 10.

The finger plate 116 extends substantially the entire length of the roller 111 and at the opposite ends of the roller are push button members 118 that extend diametrically through the roller for engagement with the underside of the member 116 so that the member 116 can be elevated by pressing the push button members 118. Each of the bush button members 118 lies in a recess 119 and has a reduced diameter rod or shank portion 120 that engages the underface of the retaining member 116. The push button 118 is held in place by an arcuate retaining plate 121 that is fixed to the roller by fastening screws It will thu be seen by pressing the push button 118, the member 116 is released and the paper edge can be inserted under the retaining member 116.

In Figs. 11, 12 and 13, there is shown a still further form of a roller used with the paper copy roller mecha nism. This roller is indicated generally at 125 and has a rod 126 extending therethrough. This roller 125 has two parallel recesses 127 and 128 extending throughout the length thereof and separated by a partition 129. Bal anced on the top of the partition 129 and secured thereto in a loose manner by a screw 130 is a clamp plate 131 having an enlarged hole 132 for the screw 130 to provide a sloppy or loose connection so as to allow pivotal movement of the plate 130 over the partition 129. One per tic-n of the plate 131 dips into recess 127 as indicated at 133 to engage and secure the end of paper sheet 43 against one side of the recess 127.

The clamp plate 131. has projections 134 struck downwardly therefrom to extend into recess 128 and to engage a flat spring 135 secured across the bottom of the recess 128 by fasteiing screws 138, Fig. 13. The plate 131 is pressed into recess 128 so as to raise the clamping end 133 to permit the paper sheet 43 to be inserted thereunder and the finger projection 134 will engage spring 135 and will return the plate 131 so that its end 133 will clamp the paper sheet 43 in the recess 127 In case the copyholder is built into the typewriter, the actuator button can be in the form of a key and included in the keyboard of the typewriter and made to be actuated within minimum force and movement, the same as that of any other key and adapted to modern touch typing and whereby the fingers can be kept in the home position. The actuator can be operated with the thumb in the same manner that the space bar is operated.

Referring now particularly to Figs. 14 and 15, there is shown the form of the invention wherein the line-by-line copy holder 140 with its press button actuator 141 built into and assembled within the typewriter shell body 142. The typewriter shell is provided with a lift cover 143 that can be lifted or removed from the front of the type writer body to provide access to the line copyholder 140 mounted within the typewriter. The line copyholder 140 has two rollers 144 and 145 which are journalled in an 7 end member 146 at one end of the copyholder 140 and in the ratchet device at the opposite end of the copyholder. The ratchet device is connected by a fiexible wire 148 that extends through a conduit 149 to the press button actuator 141 that has a press button 150 disposed be tween typewriter space bar members 151 and 152 that are coaxially aligned therewith. Roller turning and paper releasing knobs 153 and 154 are provided on each side of the typewriter so that the paper sheet can be rolled upon the rollers 144 and 145 or the rollers released to free the paper sheet or permit the insertion thereof in a manner to be hereinafter described. The actuator 141 has a rod 155 and turn knobs that extend therethrough and through the opposite sides of the typewriter body 142 and which can be turned to adjust the amount of spacing that is to be effected by the press button 150 in the manner above described in connection with the actuator 26. The line copyholder with the cover 143 of the typewriter removed is in a similar location to the location of the line copyholder above described and in front of the typewriter platen roller 157 and ribbon 158 and operable over the paper guide 159 and paper hold down bar 165. The roller platen 157 is turned by either one of their end knobs 161 or 162.

It should now be apparent that there has been provided a line copyholder adapted for use with typewriters which can be installed at a location above the typewriter forwardly of the typewriter work roller or to the right or left thereof. It should also be apparent that the operating parts of this mechanism can be embodied within the typewriter casing upon space being provided therefor. The actuator is located where it is easily accessible and is ad- 63 justable to different lengths of stroke so that the operator of the typewriter can gauge the amount of movement of the paper by the roller mechanism.

It will be further seen that there is provided a mechanism that is easy to load with the paper sheet since the ends of the paper sheet are adequately and quickly secured to the rollers and the securement is effected by simply using the pressing elements of the roller to admit the end of the paper and wherein the rollers can be turned in a manner similar to the manner in which the work roller is turned on the typewriter.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
