At my first job, the lady who did all the money used an ''adding machine'', that you would pull down a handle to give you the total!!!
I guess calculators were not on the market? Of course that was over 40 years ago.
Also every home would have 'carpet sweeper'', a little box, with wheels on the underneath, that had also bristles and you could get up crumbs, or the like.
It would have a long handle, to move around the room.
