CUPY- HOLDING DEVICE FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 390,800, dated October 9, 1888.

Application filed May 1, 1888. Serial No. 272,481. (No model.)

To all whom it may concern.-

Be it known that I, TRUMAN GARRAT PALMER, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Copy-Holding Devices for Type-Writers, of which I do declare the following to be a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My present invention has for its object to provide an improved means whereby the copyholder that sustains the manuscript or other matter to be copied may be brought directly in front of the operator of the machine while being copied, and which may be readily moved to one side when it is desired to lift the carriage of the type-writer or to place the copyholder temporarily out of use.

To this end my invention consists in the novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure l is a perspective view of a typewriterhaving my improvements applied thereto. Fig. 2 is a detail view,from the rear side, of one of the supports or clamps for holding the parts upon the type-writer, showing also an adjacent portionof the bar. Fig. 3 is a view in central cross-section through the form of carrier illustrated in Fig. 1, the standard of the copy-holder and the set-screw being shown in side elevation. Fig. 4 is a detail perspective view of a modified form of my invention. Fig. 5 is aview in cross-section on line a; .c of Fig. 4.

A and A designate the front cornenposts of the machine, which in the construction shown is of the ordinary Remington or caligraph type, these posts being of angular shape,as shown. Upon the post A is attached the clamp or support B,which,in the construe tion shown in Figs. 1 and 2, consists of asimple U-shaped piece having a threaded perforation to receive the set-screw B,which serves to securely retain the clamp or support B upon the post A in the position indicated in Fig. 1.

B designates a clamp similar to that shown in Fig. 2, but by preference provided with a somewhat longer setscrcw, B, that is provided also with ajam-nut, B, the set-screw B servingto hold the clamp or support B upon the post A, while thejam-nut B serves to securely retain in position the bar 0, that ex tends across the front of the machine, this bar being provided at one end with a long slot, 0, that fits over the set-screw B and being provided with the open transverse slot 0, through which passes the set-screw B. From this construction it will be seen that when the bar 0 is to be placed upon the front of the typewriter and in position for use the end having the open slot will be first slipped over the set-screw B until the slot 0 is above the set-screw B, after which the bar 0 will be allowed to drop to the position shown in Fig. 1 and the jam-nut B will be screwed tightly against the bar. Upon the bar 0 is mounted a sliding carrier, D, which in the construction shown in Figs. 1 and 3 is a chambered block having grooves (Z and (Z to engage with the upper and lower edges of the bar 0, and having a cut-away space, (1 from end to end to permit the block D to slide freely over the head of the setscrew B. Suitable stops, 0 and 0, will be placed upon the bar 0 to limit the movements of the sliding carrier D. This sliding carrier D is provided near its front edge with a vertical perforation adapted to receive the standard E of a suitable copy-holder, F, and a set-screw, G, that passes through a threaded opening in the front of the sliding carrier D, that serves to retain the standard E of the copy-holder at any desired height.

The copy-holder F (shown in the drawings,) is of well-known construction, being preferably provided with a series of clamp-arms, f, adapted to hold a stenographers book or other manuscript in open position, although it will be readily understood that any other suitable form of copy-holder may be employed. The standard E,that sustains the copy-holder F,is preferably bent, as at e, to enable it to pass freely over the front edge of the machine and at the same time sustain the manuscript or book in close proximity to the carriage of the machine.

From the foregoing description the operation of the form of my invention above described will be seen to be as follows: When the manuscript or other matter to be copied has been placed within the copy-holder F, the operator will slide the carrier D directly in front of the machine and to a position shown by dotted lines in Fig. 1. In this position the manuscript will be directly in front and over the roll Q, of the operator and above the keyboard of the machine, the bent standard E serving to bring the manuscript in close prox imity to the carriage J of the machine and to hold it in convenient position to be read. The copy-holder F, while standing directly in front of the traveling carriage of the machine, will not be struck thereby, but the carriage J will be free to move past the copyholder. hen itis desired to lift the carriage,the copyholder can be moved out of the way by simply sliding the carrier D to the position shown by full lines in Fig. 1, although it is apparent that without departing from the spirit of my invention the eopy-holder can be held at sufficient distaneein front of the carriage of the machine to permit it to be raised without moving the copy-holder. \Vhen the type-writer is to be covered, the bar 0 can be quickly removed therefrom by loosening the jam-nut B and then lifting the bar until the screw B is out of the slot 0 and withdrawing the bar from the set-screw B". It will be readily understood, however, that the precise details of construction of the bar 0 and its means of attachment to the machine can be varied without departing from the spirit of my invention. 1f desired, the bar 0 may be provided near the lefthand side of the machine with a one-way hinged joint, 0, uniting the two sections of the bar, and with a latch, c, pivoted, as shown at 0", so as to swing either in vertical or horizontal position for the purpose of holding the bar rigid or permitting its outer section to be turned upon the hinge. My purpose in providing the bar 0 with the hinged section is to permit such section to beswung'in close proximity to the machine in case it is desired to place the cover of the typewriter upon the machine without first removing the copyholder attachment.

In the modification of my invention illustrated in Figs. 4 and 5 of the drawings the standard E of the copy-holder is shown as attached rigidly and directly to a bar, H, which in this construction constitutes the sliding carrier for the copy-holder. This sliding carrier H is sustained upon the front of the machine by means of the clamp M, that engages with the post A of the type-writer, and by means of the clamp N, that is affixed to the opposite post, A. In this modified construction the clamp M has an angular U-shaped portion, on, provided with a threaded perforation to receive a set-screw, 0,- that bears upon the inner side of the corner-post A of the machine and serves to securely retain the clamp at the desired position thereon. The outer portion of this clamp M is provided with the outwardly turncd flange m, forming a groove or way, of, wherein the carrier 11 can slide, and, if desired, a friction-roller, I, may be journaled at the base of this groove to relieve the friction upon the bottom of the carrier, and a similar friction-roller, P, may be mounted near the top of the clamp to relieve the side friction upon the sliding carrier. The clamp N is similar in construction to the clamp M,

except that the latter is by preference pro vided also with an overhanging flange, in, that serves to prevent the end of the carrierbar H from slipping out of the clamp M when the bar H is moved so as to bring the copy holder to one side of the machine. In this construction the bar H is provided at its end with stops h and h" to limit the extent of its movement, the stop h being by preference attached by a set-screw, h, which can be readily withdrawn when the bar II is to be removed from the machine.

From the foregoing description the operation of this modified form of my invention will be seen to be as follows: The clamps M and N having been attached in position, the sliding carrier H will be placed upon the clamps. The carrier II can now be moved to the front of the machine in position to enable the operator to readily see the manuscript to be copied, and when it is desired the copy-holder can be moved to one side by merely sliding the bar II toward the left-hand side of the machine, so as to remove the copy-l1older from in front thereof. If desired, the sliding carrier H may be provided with a hinged or jointed section similar to the bar 0, above de scribed, so as to permit the cover of the machine to be placed thereon without the removal of the carrier.

.Vhile I have illustrated what I regard as the preferred forms of my invention, it will be readily understood that without departing from the spirit thereof the skilled mechanic can vary the details of construction set out within wide limits.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
