vice-adapted tob attached to a computing machine for preventing its roll of paper from p by said tensioning devmeex acquiring slack,

erting pressureon saidroll to lncrease the tension onvthe paper operation.

An object ofthe invention is tov provide 1.0 means adapted to be attached to a computing machine, to engage its'paper roll to prevent it'from unduly unwinding by inertia during the operation of the machine.

Another object of the lnve tion is toipro 21. 5 vide a tensioning'devi ce that may be readily:-

Another object of the invention is toprop c a 'crossshattd5; on whichpa roll of paper- 16 s i vide a tensioning device in which gravity controlled means is provided to automaticale ly engage theroll of paper.

Another ob'ect of the lnvention isto provide means on the tensioning device to prevent axial displacement of-the paper roll 2,2 thereon.

In general it is intended to provide a tensioning device adapted to be supplied as an ,accessory to, or standard equipment for a I computing machine, which is easily adjust- 6'35. able, adaptedto being mounted onamachine and arrangedfor gravity controlled adjust-j ment with the paper roll, to prevent the roll from unduly unwinding and forming aslack, as well as being arranged to prevent axialdis placement of the pap er roll with respect to its proper position onthezmachine.
