SPECIFICATION. forming part of Letters Patent No. 760,094, dated May 17, 1904.

Application filed January 5, 1904.

To all whom it may concern:

Be it known that we, ROBERT U. WOLFE, CHESTER T. MARTIN, and J AMES E. HANDLIN, citizens of the United States, residingat Lead, in the county of Lawrence and State of South Dakota, have invented a new and useful Copy- Holder, of which the following is a specification.

This invention relates to copy-holders for compositors, linotype operators, and copyists generally.

The object of the invention is to provide in a copy-holder of thetype in which the copy is wound upon a roller as it is copied improved means for securing the copy upon the roller, improved means for imparting movement to the winding-roller, and a novel form of screen adapted to serve the double purpose of indicating the line to be copied and concealing from the view of the operator all other matternot previously copied, and so relieving the eyes of theoperator of any unnecessary strain.

With the objects above mentioned and others in view, which will appear as the invention is fully disclosed, the same consists in an improved form of copy-holder, as hereinafter fully described, illustrated in preferred form in the accompanying drawings, and having the novel features thereof clearly pointed out in the appended claims, it being understood that changes in the structural details may be made withoutdeparting from the spirit of the invention or sacrificing the advantages thereof.

In the drawings, Figure 1 is a perspective view of the copy-holder in use, the movement of some of the parts being indicated by dotted-line positions. Fig. 2 is avertical section through the copy-holder about midway between the ends. Fig. 3 is an end view of the winding-roller, showing the mechanism for releasing the gripper.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference in the several views, F designates the frame of the copy-holder, which comprises a member 1, formed, preferably, of

Serial No. 187,827. (No model.)

iron or steel and having the ends 2 2 bent substantially at right angles to the main portion thereof to form brackets for the windingroller, plates 3 3, rigidly attached to the ends 2 2 of the member 1, and plates 44, firmly secured upon the ends of the plates 3 3. The end portions 2 2 of the member 1 are slotted, as shown at 5 5, to receive the shaft 6 of the winding-roller, which extends through openings in the plates 3 3, secured upon the ends of the member 1 by screws or other suitable fastening members, as shown. At one end the shaft 6 has rigidly attached a knurled disk or hand-wheel 7 to impart rotary movement to the winding-roller R, and at the other end a ratchet-wheel 8 is rigidly attached to the shaft and is designed to serve in connection with a pawl and operating mechanism to impart movement to the roller when such a mechanism is preferred to the hand-wheel above mentioned. The mechanism employed in connection with the ratchet 8 comprises an arm 10, which is loosely journaled upon the shaft 6 adjacent to the ratchet, a pawl 11, pivotally mounted at one end of said arm and adapted to engage the ratchet-wheel, a spring 12, which exerts a downward pull upon the end of the'arm carrying the pawl, a stop 13, to limit the pivotal movement of the arm upon the shaft, a pivoted member 14, arranged at the bottom of the plates 4 and constituting a key for operating the pawl-carrying arm, and a connecting-rod 15 for imparting movement from the key to the arm 10.

The gripping mechanism upon the windingroller comprises a rod 16, extending longitu dinally of the roller and disposed in a groove 17, formed in the outer surface thereof, a gripper-plate 18, rigidly attached to the rod, aspring 19, mounted upon the roller in a recess 20 and having the end thereof engaging the outer surface of the plate 18, and mechanism at one end of the roller for turning the rod 16 and forcing the plate 18 out of contact with the roller. The rod 16 is journaled in disks 21 at the ends of the winding-roller, and an arm 22 is rigidly attached to one end of the rod 16 external to the adjacent plate 18. A knurled disk 23 is journaled on the shaft 6 betweenthe arm 22 and the adjacent end of the member 1, and studs 24; and 25 are provided upon the inner face of the disk 23. The stud 24 is at-a suitable distance from the center of the disk to engage the armvv22 near its inner endwhe'n the'disk 23 ismoved in the direction indicated by the arrow in Fig. 3, and when brought into contact with the arm in this manner a slight rocking movement is imparted to the rod 16, forcing the plate 18 outward against the pressure of the spring 19. to permit introduction ofpapers between the plate and the roller or to enable papers to be removed from the roller. The stud 25 is adapted to contact with the arm 22 when the arm has been turned sufficiently to cause the plate 18 to swing outward from the roller to the required distance, and the contact of the stud 25 with the arm stops the forward movement of the disk 23 and prevents the stud 24% from passing out of engagement with the arm. The movement of the disk 23 by which the stud 24 is caused to swing the arm 22 to move the gripper-plate 18 out of operative position is directly opposite in direction to the move: ment imparted to the winding-roller in winding the copy thereon as the copying is completed. Consequently the ratchet and pawl associated with the winding .roller to impart rotary'movement thereto will holdthe roller against movement under the influence of the disk 23, so that the sliding movement of the disk 23 will produce only the desired effect upon the copy gripping mechanism without reversing the movement ofthe winding-roller.

preferably,of light, sheet metal and pivotally 1 mounted upon a rod 27 extendingbetween the plates 4; 4:, as shown. erably provided at its free edge with a plurality of slots28, approximately an inch in depth, which permit the operator to see when he has approached the end of his copy, and at the middle pointof the free edge a notch 29 is formed for the passage of the spring 19, which holds the gripper-plate in operative position. As may be seen in Fig. 1, the edge of the screen 26 is parallel to the axis of the shaft 6, and when the copy is evenly wound upon the winding-roller the edge of the screen will be parallel to the lines of the copy. In order to The screen 26 is pref In order to support the copy-holderin convcnient position relative to the compositors type-case or the linotype or type-writing machine by means of which the copying is to be done, a block 31 is preferably secured upon the rear surface of the supporting member 1,

and a clamping-bolt 32 is extended through the block for engagement with a bracket B of any preferred construction.

. then imparted to the winding-roller by means of the knurled disk 7 or the latch mechanism at the other end of the roller to wind the copy upon the roller until the first line thereof ap pears above the free edge of the screen 26. The line thus exposed is then copied, and movement is then imparted to the roller to bring the second line into view above the edge of the screen, When the hnes correspond in' width to one or more teeth of the wheel 8, the

.duced by turning the disk 7 by hand. Vhen the copying is.completed,'the'removal of the copy from the. roller maybe quickly accomplished by swinging the pawl 11 out of contact with the ratchet-wheel 8 and pulling upon the end of the copy. The pawl being out of contact with the ratchet-wheel, there is nothing to interfere with the reverse rotation of the roller and the copy will be allowed'to unwind freely until the gripping-plate 18 is uncovered, when the pawl will be swung again into engagement with the ratchet-wheel, and

the disk 23 will be given a slight turning movement upon the shaft 6 to effect the release of the copy from the gripof the plate 18.

It will be noted that the copy-gripping plate 18 extends across substantially the entire width of the copy, so obtaining a firm hold upon the copy and preventing any tendency to tear the copy, while at the same time insuring the proper position of the copy upon the winding-roller. The mechanism by which the copy is released from the winding-roller is of very simple character, may be instantly operated, and cannot become disarranged. It will also be noted that the portion of the copy exposed to View at any time comprises only the line to be copied and a few lines of the matter already copied, thus reducing to a minimum the surface exposed to view, indieating clearly and positively the line to be copied and lessening the strain upon the eyes of the copyist. The indicator being provided with the slots 28 at its free edge enables the operator to tell when he is approaching the end of his copy, so that the arrangement of the lines in the transcript may be determined accordingly.

The entire structure of the copy-holder is of such character that it may be used indefinitely without appreciable wear upon any part thereof and without liability to derangement of any portion of the mechanism. All parts of the copy-holder except the body of the windingroller, which is made of wood or other light material, are formed of metal in order to obtain sufficient strength without great bulk. The device is generally attachable to a compositors type-case, or it may, if preferred, be supported upon a bracket mounted upon a type-writer or linotype-machine. If preferred to mount the copy-holder independently of the type-case or the machine operated by the copyist, a suitable pedestal may be employed in lieu of the bracket B, and the clampingscrews will enable the holder to be secured in any desired position.

The operation of the copy-holder with an ordinary copy has been clearly explained in the foregoing pages; but the adaptation of the copy-holder to the display of short pieces of copy which could not be secured upon the winding-roller quickly enough to justify their arrangement in the ordinary manner has not been brought out. The spring 80, which holds the screen 26 in contact with the windingroller, forms means for effectively supporting short pieces of copy,-as the spring can be instantly drawn forward from the screen 26 and the copy gripped by the spring when the copy is introduced between the spring and the screen and the spring is released. The use of the copy-holder in this manner will result in a very material saving in time when an operator has to set up a number of short pieces of copy, as the time necessary to secure the several pieces under the clamping-plate 18 and then bring each piece of copy into position to expose the first line thereof above the screen is saved.
