Accordingly,` the arm'26 with the disc 47 'attached'thereto can be adjusted relative to thediscH 46 and the bracket'arm 20. The s'pring'31 on theshaft 27 biasingly retains the balls in the opposingdepressions of the'disc's. Ac# cordingly, thepad 36 can be lifted and lowered'withoutA any need for releasing any of the parts. I At times, it is desired that the bracket arm, which is of'. channel section, be mounted on the top side oftheinstru# ment board rather than from underneath. Forthilspilrpose, abracket arm 20 having a slot'21' throughiwhich the same spring loadedscrew 22 is extended andtightened upon the top of the instrument board. 'This channelbracket arm is turned up with its vchannel flanges extending upwardly and adisc 24 is welded to the opposite side ange of the channel arm. Thisdisc 24 wil'lhave the same depressions and is engaged by theball 34 of `the'disc 32. The adjustment of thepad 36 and thebracket 26 upon theshaft 27 and bracket 20' is effectedrin the same manner as above described. v

Attimes it is desired that the pad be made separable from the bracket so as to render it quickly portable. For this purpose and as a rnodied form of the invention thearm 26 is replaced by anarm 53 that has atapered keyway 54 in its upper face thereof. Thepad 36 Vwill be replaced by apad 51 that has akey projection 52 adapted toslidably t thekeyway 54. Aclamp 55 is secured upon apivot pin 56 by itsprojections 57. The pin is supported` on thepad 51 by the;projections 58. Thekey projection 52 is also tapered so that' itfts from only one side of thekeyway 54 but when wedged therein a tight rigid coni nection is effected therebetween.

On the underside of the pad there is provided atray 60 that is attached by itsflanges 61 as by welding to the underface of thepad 36. This tray has lighteningrholes 62 and aside opening 63 through which paper sheets can be' inserted or removed from the tray. In order that these sheets can be more readily graspedand drawn frornthe tray the side edge of the tray is cut away at one location thereon at 64. This tray is adapt-ed to containpaper heets, such as bills or invoices as indicated at: 65 Vin ig. 3. Apencil 67 is connected to asleeve 68 from which extends a wire orchain 69 that is attached to a hole opening 70 in the upper end of the pad. Thispencil 67 can be extended into apencil holder'sleeve 71 that is fixed byanges 71 to the writing surface close to one side edge`thereof.

Running longitudinally through thepencil sleeve holdery 71 is awire spring 72 that is xed at one'end 73 tothe pad surface and over which thepencil 67 can be extended to depress the spring through anelongated slot 74 in thepad 36 under thesleeve 71 and itsprojection 72 be made to extend downwardly through theopening 63 of the tray to provide a stop beside the paper sheets and prevent their removal therefrom either accidentally or purposely until thepencil 67 has been removed from thelpencil sleeve holder 71.
