UNITED As'rarrs PETER (irRABIiER7 OF ROCKY RIVER, OHIO.

COPYHOLDER APARATUS.

` Application filed Iune'21,

To all whom t may concern." f Be it known that I, Pn'rnn GRABLER, a citizen of the United States, residing in' Rock;T River, county of Cuyahoga, and State of Ohio, have invented a new and useful mprovement in Copyholder Apparatus, of which the following is a specification5 A My invention relates to apparatus for holding copy in the form of loose sheets, or books 'or otherwise.

@ne of the objects of my invention is a simple,'inexpensive, and light weight apparatus which does not tip over easily.

Another object is to provide such an apparatus with means for tilting the copy support platethereof to any desired angle.

Another object is to provide such an apparatus with all necessary appliances for conveniently and quicklyplacing copy onto the apparatus and removing it therefrom and to firmly hold this copy on the apparatus vwithout any auxiliary appliance.

Another object is to provide such an apr raratus with indicating means which is adjustable as to thickness of the copy as well as to longitudinal positions on the copy.

Another object is to provide such an apparatus with adjustable friction means lbetween the base and the upper structure to permit this friction means to be adjusted periodically without any auxiliary appliances to permit this Lipper structure to be moved into desired positions at all times n without shifting the base thereof and to automatically retainthese positionsat all times.

Another object is to provide such an apparatus with adjustable friction means between the members of the indicating means to permit this friction means to be adjusted periodically without any auxiliary appliances to permit the indicator bar to be -moved longitudinally and radially without shifting they base or the supportplate and to automatically retain this position at all times.

I am aware that copy holders have heretofore been made, but I am not aware that such holders have been made with all of the necessary or convenient appliances incorporated therein as is done in the present invention. 'The copy holders heretofore ymade are .either top heavy and tip over easily; .are not provided witha simple and 1924. Serial No. 721,414.

efficient clip means to easily place any thickness of copy onto ythe support plate, and to easily. remove it therefrom, and to firmly hold it thereon;y they require repairs quite frequently as the parts becomeworn.

The present invention aims to provide a copy holder apparatus which overcomes the defects found in former holders, which has incorporated therein not only all appliances or conveniences necessary for the purposes of such` an apparatus, vbut also the necessary means to vtake up wear without any auxiliary tools; thereby saving considerable time in the operation of the'apparatus as well as eliminating practically all repairs.

I attain these Vobjects and these advantages by the mechanism illustrated in the accompanying drawing in which:

Fig. 1 isa front elevation of a copy holder apparatus embodying the features of my invention. 1

Fig. 2 is a section, taken on a 'vertical plane indicated bythe line 2-2 in Fig. 1, showing the. structural detailsmore clearly.

Fig. 3 is a section, taken on a horizontal plane indicated by the line 3-.-3 in Fig. 2, showing the relations between the support plate and the indicator means more clearly.

Fig. 4 is a section, taken on a horizontal plane indicated by the line 1 -4L in Fig. 2, rshowing the hinge joints between the base and the support plate and between the sup.- port plate and the indicator means, and also the frictionl means of these joints more clearly. j

Fig. 5 is a section, onv a larger scale, taken on a horizontal plane indicated by the line 5 5 in Fig. 2, showing the joint and friction means between members of the indicator means more clearly.

Fig. 6 is a section, on a larger scale, typical of the various joints of the apparatus, as on line 6-6 of Figs. l and 3 for instance.

Similar reference characters refer to similar parts throughout the views.

The apparatus shown in the accompanying drawing comprises, principally, the base A, the copy support plate B, the copy clip C, the indicator bracket D, the indicator bar E, and the vtelescopic arm F.

' The base A is made suiiiciently heavy to provide a substantial support for the other parts of the 'apparatus and'is, preferably,

formed substantially triangular to provide a good surface on the bottom thereof to prevent tipping` over of the apparatus.

It is observed that the bottom of the base A is provided with three annular rest pads 10, of rubber or otherwise, one at each apex of the triangular` base, and that these pads project below the bottom of the main body of the base., This arrangement provides a three point rest for the apparatus to permit the same to be set upon une-ven surfaces and to rest securely under practically all conditions. This feature is important in an apparatus of the kind under contemplation.

The lug 11 projects upward from the top of the base A, above or opposite one of the pads 10, preferably with the longitudinal axis thereof inward of the longitudinal axis of this pad, to provide a good support for the structure mounted on the base and to aid in preventing the apparatus from tipping over. In other words: the lug 11 is disposed on the top of the base, within the three pads located on the bottom of the base, and closer to one of these pads than to the other two.

The copy support plate B is made of thin material to keep the same as light in weight as possible and is formed with the rib 12 to stiffen the same.

A pair of ears 13 and 14 are bent down from the lower end of the support plate B, on cach side of the rib, and straddle the lug 11.

The bolt 15 passes through both of these ears and through the lug and forms a hinge pin to permit the plate B to swivel on the base A.

The head 16 of the bolt 15 rests against the ear 13 and the wing nut 17, threaded to the bolt l5, bears against the ear 14.

Since the ears 18 and 14 are made of thin material they are flexible to some extent and can be manipulated by the nut 17 to increase or decrease the friction between these ears and the lug. For instance, after this swivel joint wears and becomes too loose to retain the plate B in adjusted or desired position, the nut 17 may be tightened, thereby forcing the ears toward each other and against the sides of the lug l1; this tightening can be adjusted to a point where sufficient friction is created between the ears and the lug to retain the plate B in adjusted position but permit the same to be swiveled on the bolt 15 without further manipulation of the nut 17 or without further auxiliary to'ols. A

A pair of ears 18 and 19 are bent up ward from the lower end of the pla-te B near the sides thereof.

The indicator bracket 'D has the ends thereof bent down to form the ears 20 and 21 disposed between the ears 18 and 19 vrespectively as clearly seen 'in Fig, 4l,

The tubular rivets 22, shown on a larger scale in Fig. 6, may be employed on the bracket as a swivel or hinge pin. Such tubular rivet is light in weight, is easily installed, and is easily tightened either by the heads thereof as is well known in the art or by expanding the same through the hole therein.

The indicator bar E is made very light in weight and is provided with the handle 23 to conveniently permit of taking hold thereof for the purpose of manipulating the bar E to shift the same up or down to desired lines or positions on the copy or toward or away from the plate B to 'accommodate different thicknesses of copy.

The telescopic arm F, also very light in weight, is composed of the members 2a4 and 25. The outer end of the upper of the members 24C is hinged to the bar E while the outer end of the lower of the members 24 is provided with the pin 26 which is guided in the slot 27 provided in the bracket D for that purpose.

The outer end of the upper of the members is provided with the pin 28 which is guided in the slot 29 provided in the bar E for that purpose, while the outer end of the lower of these members 25 is hinged to the bracket D.

The remaining ends of the members 24 are hinged to each other while the remaining ends of the members 25 are also hinged to each other.

The members 24 and 25 cross each other and are hinged to each other at these crossings. The tubular rivet 22 is also employed at these hinge joints to provide light Weight structure and adaptability for adjustment as previously set forth.

At the crossing of the middle members 2% and 25, the hinge joint is formed as shown on a larger scale in Fig. 5. This joint comprises the bolt 30 passing through both of the members, the washer 31 between the head of the bolt and the member 25, the washer 32 adjacent to the member 24, and the wing nut threaded to the bolt 3() and bearing against the washer 32.

Upon manipulation of the wing nut 33, any desired frictional engagement between the members 2stand 25 may be attained to permit the arm F to be lengthened or shortened readily to permit the bar E to be moved up or down readily and tol retain this-bar in any desired position without any auxiliary instrument. j

The guide feature of the arm F is provided to permit the bar E to be moved up or dow-n; the free ends of the outer members 2a and 25 slide in and are guided in the slots 27 and 29 respectively for the purpose of always retaining the bar E, in a horizontal position irrespective of what vertical position it is moved into.Y

The copy clip C is mounted near the upper end of the support plate B and is journaled in the brackets 34 which are secured to the back of the plate B.

The clip C itself comprises the horizontal clip bar 35 disposed just inside of the upper edge of the plate B, the downwardly eX- tending side members 36, and the journal members 37 substantially parallel with the clip bar 1 The bar is disposed on the front of the plate B while the members 37 are journaled in the brackets 34 on the back of the plate B.

The coil springs 38 are disposedover the respective ournal members 87, each having the end 39 thereof engaging one of the membersr 36 and the end 40 thereof resting against the back of the plate B. The springs 38 are so wound and mounted that the tension thereof always tends to move the clip bar 35 toward the plate B to normally hold the copy thereon.

Then it is desired to place a copy on the plate B, the bar 35 is moved forward, away from the plate, B, the copy is then placed en the plate and," upon releasing the bar 35, the springs 38 will rotate the clip C in its journal and force the bar 35 toward the plate B and thereby hold the copy thereon.

It is observed that the clip bar 35 of the clip C lies across the plate B at the eX- treme upper edge thereof, that the members 36 are disposed some distance on each side of the plate B to permit the copy to extend therebetween, and that the members 37 are disposed on the back of the4 plate B so that they will not interfere with the copy.

By disposing the members of the clip C as set forth, the indicator bar can move up to the to a of the plate B and the copy G can readily liang over the upper edge of the plate as indicated in dotted lines in Fig. 2,

liloditications may be made within the scope of the appended claims; therefore, without limiting myself to the precise construction and arrangements of elements shown and described,
