Don't be fooled by the title but that was the name given to these Dinning Room pieces. Note the wheels on the bottom. These images and information come from The Furniture Gazette ©1884.
THE Dinner-waggon is a most useful adjunct to the dining-room, although it is not so much required now as it used to be, and for this reason, doubtless, that the modern sideboard is provided with more shelf-room, &c, than formerly; many of the modern designs form a sort of combination dinner-waggon and sideboard. In a small-sized room a piece of furniture of this description is found very convenient. When the dining-room is large enough to conveniently hold a dinner- waggon, space should certainly be spared for one. It should have a prominent position, so as to be seen to advantage. The details, should match the other articles in the room, and notably the sideboard, which latter is necessarily the most important piece of furniture in the apartment.
