Application May '7, 1949, Serial No. 915966- "This invention relates to improvements in brackets or supports by means-of which copyholders may be moun'ted-on typewriter platforms or similar supports.

"Secretarial :desks are commonly provided with platforms constituting extensions .of the desks and to which typewriters or similar machines may the secured. When the typewriter is .not in use, such platform with the typewriter mounted thereon may lbe swung or otherwise shifted into ipositionwithinaipedestal of the desk. Since it: is frequentlysdesirable to use copyholders in connection with theitypewriter'platforms of desks of :this type, :difiicultyhas heretofore been encountered in mounting these copyholders on'the platforms for the reason that the platforms are necessarily limited in their width, and furthermore, the copyholders .as now commonly used are too :large to be swungwith the typewriter and its supporting platform into an inoperative position within the pedestal of the desk.

(One of theobjects of this invention is to provide aibracket by means of which 'a copyholder may readily be supported on a -typewriter platform of a .desk in such a manner that a copyholder together with .a partof the. bracket can be quick- 1y :andeasily secured 'to or detached from the platform. Another object .is to provide brackets of improved construction which comprises two members, one of which may be permanently secured to the platform .andthe other of which has the copyholder secured thereto rand is .releasably secured to the 'first lbracketrmember. .A further object of this invention is to provide brackets 'of strong and..-rigid construction which support the copyholder beyond :an edge of the platform. .Another object to provide --acopyholdersupporting bracket with apivotal mounting for the usual lever which :is usedfor vertically moving a part ,of the copyholder. It is also an objectof this invention .to provide brackets'of this type which can be used without interfering with the usualpedestal door .of a .desk.

Other objects and advantages :will .be apparent from .the followingdescriptionofi one embodiment of the invention and the novel features will .be particularly pointed out hereinafter in connection with the appendedolaims.

:In the accompanying drawings:

In 1,8 represents a portion of .a pedestal desk which is provided witha platform it =mounted-on the desk in such a manner that it can be swung into operative position as shown .in Fig. 1, and into an inoperative position in which the platform together .witha typewriter .or other .machineinounted thereon may be inserted 'intoand housed within the pedestal of the desk. The width-of these platforms is .SllCh that when a typewriter'is secured there-to, there .is usually not sufiicient'room to support a copyholder l 0 .on the platform. 1! represents the usual door which closes the. pedestal of the :desk when the plat- -form at with .a .machine mounted thereon is housed within the pedestal.

1 .In order tosupport a CQDYholder on the platform-911 provide a ,pair of brackets t2 and I4 whichuare preferably made in two parts or members which are readily separable. One .of these parts of each bracket is a base member l5 to which the other part or member of the 'bracket may be quicklyattachedor removed. The base members may be of :any suitable construction, those shown being of Z-shaped cross section, each including a flange iii which may be suitably secured to the platform 9 in any suitable manner, for example, by means of bolts l! or other fastening means. Each of these base members also includes an upwardly extending flange or leg .l-Bterminating at its upper edge in a substantially horizontally extending flange it to which flange the other member of the bracket may be releasablysecuredin any desired manner.

The other or removable members of the brackets are preferably-made of sheet .metal bent or formed to include substantially flat horizontal portions .21 and 22. The portion 2! .of each bracket is formed vto lie face to face upon the horizontalfiange l-Q of the base member of the bracket. .The other portion 522 of the removable member of-the bracket-extends beyond theouter edgeof the platform 9 and the .base or foot portions 23 of a copyholder may be suitably secured to the horizontal portions 2.2 of the removable bracket members in any suitable manner, for example, by means of bolts 24 or other fastening means which extend through apertures in the foot portions of the copyholder and in the horizontal parts 22 of the brackets. Consequently, the copyholder may be more or less permanently secured to the removable parts or members of the brackets |2 and I4.

In order to firmly support the copyholder, the removable members of the brackets are reinforced to render them rigid, and for this purpose, in the particular construction illustrated, each removable member is provided between the portions 2| and 22 thereof with a reinforcing part 25, which in the construction shown is of channel or inverted U-shape. The portions 2|, 22 and 25 may be formed of a single piece of sheet metal bent into the desired shape, or this part of the removable member may be made of sep- I arate pieces secured together, for example, by welding.

In some types of desks the door II for the desk pedestal extends at a considerable distance above the upper surface of the platform 9, and by making the reinforcing portion of channel shape, this reinforcing portion serves the further purpose of receiving or straddling the upper portion of a pedestal door of this type, as shown in Figs. 4 and 5. In the particular construction shown in Fig. 1, a door is shown which does not extend materially above the upper flanges H! of the fixed bracket members, and this door, therefore, does not extend into the reinforcing channel portions 25 of the brackets, and when used in connection with desks having doors of this type, the channels 25 may be replaced with reinforcing members of othe shapes or forms. In order to prevent rattling and damage to the finish of the upper portions of the doors, the inner surfaces of the channel portions 25 are preferably lined with a suitable felt or other cushioning material 21.

In order to support the copyholder in such a manner that it is mounted rigidly on the platform 9, it is also desirable to provide a reinforcing member extending crosswise of the member or portion 25. For this purpose, the horizontal portion 2| of each of the removable parts of the brackets is provided with an upwardly extending flange 28, preferably formed integral therewith, and a truss member an is also provided on each bracket which straddles the reinforcing or channel member 25 thereof. This truss member is rigidly secured to the upright flange 28, for example, by welding, and the outer portion of the truss member is also rigidly secured to the horizontal supporting part 22, for example, by means of a flange 3| integral with the truss member 30, which may be welded or otherwise secured to the horizontal supporting part 22. If desired, the inner end of the truss member may also be provided with a flange o integral part 32 which may be welded or secured to the portion 2| of the removable member of the bracket.

By means of the construction described, the truss member and the parts associated therewith resist flexing of the removable member of the bracket in one direction, and the reinforcing member or chanel portion 25 resists flexing in a direction transversely thereof, so that a strong and rigid bracket results which can be made of relatively light gage sheet metal. Consequently, the removable bracket member does not add materially to the weight of the copyholder to which it is secured.

Any suitable or desired quickly detachable connection may be provided between the two parts or members of each bracket. In the construction illustrated, this is accomplished by means of a locking bolt 35 provided at one end thereof with a web or wing 36 for turning the bolt, and at the other end thereof a locking pin 31. The bolt 35 extends loosely through a hole in the horizontal portion 2| of the removable bracket and the pin 31 is of such length as to prevent removal of the bolt through the hole in the part 2|. This pin 31, when the bolt 35 is turned in one direction, cooperates with a suitable cam member, generally designated as 40, secured to the lower surface of the horizontal flange |9 of the fixed member of the bracket for pressing the portion 2| into tight engagement with the horizontal flange I3. Fastening devices of this type are well known and are, therefore, not herein described in detail. Any other suitable quickly releasable fastening device may be provided if desired.

When it is desired to connect the removable member of the bracket to the fixed member, it is merely necessary to insert the end of the bolt 35 carrying the pin 31 through an opening in the flange I9 into position to engage the cam member 40. By turning the bolt 35 by means of its handle portion 36 through slightly less than half a revolution, the pin 31 will engage the cam faces to draw the bolt 35 downwardly and thus press the part 2| into engagement with the flange |3. Similarly somewhat less than a half turn in the opposite direction will release the bolt so that the removable member of a bracket may be quickly detached from the flange 9 of the fixed bracket member.

The two removable bracket members are similar in construction except that the portion 22 of the left hand bracket i2 is longer in the direction of the adjacent edge of the platform than the portion 22 of the right hand bracket l4, and consequently, the channel 25 of the bracket I2 is also considerably longer than the channel of the bracket M. This enables the brackets to be readily adapted for use with typewriter housings or bases of various widths, since the base members of the brackets are secured to the platform in such manner that the rear portion of the base or frame of the typewriter may extend between the base members of the brackets. For this purpose, the portion 22 of the left hand bracket is provided with additional pairs of apertures, as clearly shown in Fig. 3, through which the bolts 24 may pass when the brackets are spaced farther apart to accommodate typewriters of greater widths.

The bracket part M on the right-hand side of the copyholder is preferably provided with'a pair of upwardly extendin spaced ears or lugs 42 which may be secured to or formed integral with the upstanding reinforcing flange 28. These two ears or lugs are spaced apart to receive a lever 43 such as commonly used in connection with a copyholder to raise and lower the copy supporting part 44 thereof, and this lever 43 may, consequently, be connected with the lugs 42 by means of a pivot pin or bolt 46. By means of this construction, the copyholder lever, being mounted on a removable bracket member which in turn is secured to the copyholder, will remain in correct relation to the copyholder when the same is removed from the desk platform.

The brackets described have the advantage that they rigidly support the copyholder on the plat-' form of the desk, and furthermore, support the same beyond the outer edge of the platform so as to leave ample room on the platform for the typeegaogasv writer or other machine. The 'fixed bracket parts :are ofsuch sizeas not to-interferewith the'movement of the platform 9 with the machine mounted thereon'into the desk pedestal.

It'will'be understood that various changes in theldetails, materials-and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention, may-be made by those skilled in the art within theprinciple and scope of the invention, as ex pressed in the appended claims.
