CLARENCE H. CALDWELL, OF OAK PARK, ILLINOIS.

Specification of Letters Patent.

Patented Aug. 7, 1917.

Application filed February '7, 1916. Serial No. 76,634.

To all whom it may concern:

Be it known that I, CLARENCE H. CALD- WELL, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Copy- Holders for Type-Writers, of which the following is a specification.

This invention contemplates an improved copy holder to provide a device of this character which may be fixed to a type-writer to support a copy book in convenient position relative thereto.

The invention has as a further object to provide a device of this character wherein body of the holder may be folded to inoperative position to lie upon the typewriter carriage and wherein movement of the body to such position will simultaneously shift the arms supporting the device froma position extending laterally from the body of the typewriter to inoperative position folded in the rear of the typewriter.

A further object of the invention is to provide a device of this character wherein the body of the holder may be positioned above the typewriter carriage either toward or away from the operator so that the copy book may be brought within easy vision.

The invention has as a further object to provide a copy holder wherein the body of the holder may be easily moved to a position overlying the key-board of the typewriter so that the body of the holder may be used to support a copy book when taking notes.

And a still further object of the invention is to provide an improved copy holder having a supporting bracket of such construction that the said bracket will coact with the body of the holder to efliciently maintain the copy book in proper position upon the holder.

Other and incidental objects will appear as the description proceeds and in the draw ings wherein I have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a perspective view looking at the rear side of my improved copy holder and showing the device in normal operative position upon a conventional type of typewriter,

and has as its primary object Fig. 2 is a top plan view showing the body of the holder folded to inoperative position to lie upon the carriage of the typewriter,

Fig. 8 is a perspective view of one of the attaching clamps employed for connecting the bracket arms of the holder to the type writer, and

Fig. 9 is a perspective view showing one of the toothed segments carried by the body of the holder and the operating lever or finger associated therewith.

Since the copy holder of the present invention is designed for attachment to a typewriter I have, in order that the mounting and operation of the device may be fully understood, illustrated in the drawings a conventional type of typewriter indicated at A and in this connection, it may be stated that my improved copy holder is designed for use in connection with any conventional type of typewriting machine.

In carrying out the invention, I employ attaching clamps 10 one of which is illustrated in detail in Fig. 8 of the drawing. These clamps are formed to embrace the rear uprights of the frame of the typewriter A at their upper extremities and are provided with set screws 11 adjustable to engage the said uprights with the said set screws extending forwardl-y o f the ityp'ewriter frame beneath the typewriter carriage which has for convenience, been designated B. Extending laterally from the clamps 10 are spaced ears 1% and pivoted at theirinnerex treinities between the said ears, are bracket arms 13 detachably connected to the ears by pivot pins 14. The arms 13, at their outeriextremities, are curved upwardly and are terminally enlarged to pivotally receive carriage supporting arms 15. The arms ;15 are-longitudinally bowed to extend'inwardly toward the carriage B ofrthe typewriter and terminate at their inner extremities in a plane abovethercarriage. At their outer extremities, the arms 15 are terminally enlarged to rest against the terminal enlargements at the outer ends of the arms 13 and are detachably connected thereto by-pivot pins 16.

Extending between the inner extremities of the arms 1 1 in a plane abovethecarriage B of the'typewriter,is-a carriage 17. This carriage may be formed from a strip of sheet'metal or other similar material and ad jacent its extremities, isprovided with offset portions- 18with theterminals 19 of the carriage seating against the upper faces of the arms 15- at their free extremities. Pivotally connecting the carriage 17 to the arms 15 vare upstanding stub shafts 20 which extend freely-throughithe terminals 19 of the carriage 17 andliare fixed in the inner extremi ties ofthe saidvarms. The stub shafts 20 are provided with collars 21'which engage the terminals :19 of the carriage, said shafts being preferably screw threaded, as more particularly shown inF 3 to engage the arms 15 and being thus detachably connected thereto. At their upper extremities, the shafts 20 are provided with beveled gears 22 keyed to the said shafts or secured thereto in any other suitable manner. It will be notedthat the offset portions 18 of the carriage are arranged to extend upwardly from the arms 15 andmounted upon the said olfset portions and extending freely therethrough are rock shafts 23 to the outer extremities of which are fixed toothed segments .24 meshing withthe beveled gears 22.

Fixed to the inner extremities of the said rock'shafts and preferably detachably connectedithereto, are operating levers or fingers 25-shown in detail in Fig. 90f the drawings. The fingers 25 areeach'notched upon one side thereof to fit within suitable notches .26 :formed inthe'ca-rriage 17 adjacent the 'oifset portions 18 thereof and at their free extremities are provided with longitudinally extending slots 27 having contracted throats.

At, a point midway its ends, the carriage 17 is formed with: a depending substantially U-shaped {POI'lifOl'llQS upon the sides 29 of which are formed spaced laterally projecting and upwardly presented hooks 30 extending forwardly from the carriage. Swingingly mounted upon the U-shaped 'portion28 of the carriage 17 is a supporting arm or bracket 31. This bracket, adjacent its lower extremity, is provided with a forked terminal 32, the arms of which, at their outer extremities fit freely between the sides 29 of the U-shaped portion 2801? the and adapted to receive the arms of the fork 353 to engage therewith in the manner best illustrated in Figs. 1 and 5 of the drawings. Adjacent its upper extremity, the bracket 31is bifurcated to form laterally and oppositely projecting arms 35 which are longitudinally bowed to extend rearwardly of the carriage 17 and the free terminals of which are presented toward each other to receive the body portion 36 of" the copy holder. The body portion 36 of the copy holder will, for convenience, be termed a rack body and includes a suitable frame which may be formed of metal or other suitable material and to which is connected a reticulate body portion 37. At its lower ex tremity, the frame of the rack body is provided with a channel member 38 adapted to engage the lower end of a'copy book with the book resting against the reticulate body portion 37 of the rack body. Pivotally connecting the rack body to its supporting bracket 31, are loops 39 which are swingingly connected to the inwardly presented termi nals of the arms 35 of the said bracket and engage loosely within clips 10 secured to the rear side of the frame of the rack body at its upper extremity. Connected to the frame of the rack body, at its lower extremity and upon the rear side thereof, are spaced lugs 41 which project laterally and rearwardly from the rack body and carry a pivot rod 42. This pivot rod is adapted to be detachably received within the hooks 30 of the carriage 17 in the manner best shown in Fig. 5 of the drawings to cooperate with the bracket 1 in supporting the rackbody in normal operative position upon the carriage with the said rack body inclined rearwardly relative to the carriage, as illustrated.

Attention is now directed to the fact that the bracket 31 is longitudinally curved adjacent the inner extremities of the arms 35 thereof to extend inwardly toward the rack body and is thus formed with a shoulder 43 against which the rear side of the rack body is adapted to abut for supporting the rack body in normal operative position, as particularly shown in Fig. 5. As illustrated in this figure, a copy book conventionally shown at 44, may be placed against the rack body with the lower end of the book engaged within the channel member 38. As the leaves of the book are turned, they are preferably carried over the upper end of the rack body and inserted between the arm 35 of the bracket 31 to confront the rear side of the rack body. The leaves so turned will consequently be disposed between the shoulder 43 of the said bracket and the rack body and the bracket 31 will thus cooperate with the rack body to provide a clamp or holding member for the leaves of the book so turned, it being observed that the rack body when in normal operative position, will gravitate at its upper extremity toward the bracket 31 to effectually hold the leaves of the book between the rack body and the said bracket.

It will therefore be readily seen that I provide a very convenient and eflicient arrangement whereby the copy book will not only be held in proper position upon the rack body but also wherein the used leaves of the book, as they are turned will be held in a position out of the way.

Connected to the frame of the rack body, at its ends, and adjacent the lower extremity of the said body, are laterally projecting brackets or arms 44, the outer terminals of which are bent laterally and rearwardly and pivotally support catch members 45 adapted to extend in the rear of the rack body to confront the inner sides of the operating levers or fingers 25. Fixed to the outer extremities of the said catch members, are laterally projecting pins 46 adapted to be removably received within the slots 27 of the said levers in the manner illustrated in Fig. 1 of the drawings with the catch members disposed in substantially horizontal position. The purpose in providing the slots 27 with contracted throats as previously set forth, will now be apparent since it will be seen that under ordinary circumstances, the said throats will act to maintain the pins 46 of the catch members engaged within the said slots.

From the preceding description, it will be seen that my improved copy holder may be attached to substantially any conventional type of typewriter in the manner illustrated in Fig. 1 of the drawings with the rack body supported above the carriage of the typewriter to receive a copy book. The space between the

arms

13 and 15 of the copy holder is such that the carriage of the typewriter will move freely therebetween and accordingly, the arms 13 may be moved about their pivot pins 14 and the arms 15 simultaneously-and correspondingly moved about their pivot pins 16 to position the rack body 36 of the copy holder either toward or away from the operator of the typewriter to bring the copy book within easy vision. I further provide an arrangement whereby the rack body 36 may be used as a support in taking notes. To accomplish this end, the pivot rod 42 of the rack body is disconnected from the hooks 30 of the carriage 17. The forward extremities of the catch members 45 are then depressed to disengage the pins 46 of the said catch members from within the slots 27 of the operating levers 25. The lower extremity of the rack body may then be moved forwardly over the carriage when the bracket 31 will swing upon its pivot rod 33 so that the rack body may be positioned to overlie the keyboard of the typewriter in the manner shown in Fig. 4 of the drawings with the lower extremity of the rack body resting against the key-board and with its upper extremity resting against the typewriter frame. When so arranged, it will be seen that an operator may readily place a notebook against the rack body to be held in convenient position thereby so that notes may be taken without difliculty.

As will be well understood, my improved copy holder will normally be arranged upon the typewriter as shown in Fig. 1 ofv the drawings with the rack body supported in position to receive a copy book. In order that the typewriter may be covered or disposed within a desk in the well known manner without the necessity of removing the copy holder, I provide an arrangement wherein the copy holder may be folded to inoperative position upon the typewriter. The carriage 17 of the device is first shifted to a position adjacent the rear of the typewriter with the arms 15 disposed over the arms 13 as particularly shown in Fig. 1. The rack body 36 is then swung upon the hooks 30 by its pivot rod 42 when the loops 39 will swing about the arm 35 of the bracket and within the clips 40 to permit bracket 31 to swing about its pivot rod 33 so that the rack body maybe moved to a position resting upon the carriage B of the typewriter as illustrated in Fig. 2 of the drawings. l/Vhen the rack body 36 is thus swung about its axis, the catch members 45 will engage the levers 25 to move the said levers forwardly in an arc, the pins 46 of the said catch members moving within the slots 27 of the said levers and the catch members rocking upon their pivots as the rack body is shifted. Such movement of the levers 25 will, as will be readily seen, be communicated through the rock shafts 23 to the toothed segments 24 which will then engage the beveled gears 22 to turn the stub shafts 20. The stub shafts 20 being fixed tothe innerextremities of the'arms -15, rotation of the said shafts by the for-ward movement of the levers 25 will swing the

arms

13 and 15 simultaneously about the pivot points let to dispose the arms to folded position in the rear of the typewriter as shown in Fig. 8 of the drawings. Consequently, when the rack body is swung to inoperative position to lie against the carriage of the typewriter, the

arms

13 and 15 of the holder will be automatically swung :to inoperative position in the rear :of the typewriter so that the typewriter may be covered or disposed within a desk without the necessity of removing the copy holder. Whenthe rack body36 isagain swung from inoperative position to operative position, as shown in Fig. 1, the stub shafts 20 will, as will be readily understood, be rotated llIl an opposite direction from that previously described to again simultaneously swing the

arms

13 and 15 about the pivot :points 14 to operative position. It will therefore be seen that I provide a very convenient and efficient construction for the purpose set forth.
