As the 19th Century progressed larger farms were being built. Below is an example of one such farm. David Lyman lived in Conn. and had this barn built. I've included what the author of the Barn Plans and Outbuildings author wrote.
THE BARN" OF MR. DAVID LYMAN.
By means of a hay fork and a number of travellers, the hay is taken from the loads and dropped in any part of the immense bays. The forks are worked by one horse, attached to a hoisting machine, of which there are two, placed near the great doors during the haying season, as indicated by the letters marked H, P, in the plan, figure 2.
The Feeding Floor is entered by several doors. Two double doors open upon a spacious floor in the rear of the horse stalls, which extends through the middle of the main barn. The northwest corner, figure 3, is occupied by a large harness and tool room, with a chimney and a stove. On the right of the front entrance is the carriage room, which is closed by a sliding door, or partition. There is room on the open part of this floor, behind the horse stalls, and adjacent, to drive in three wagons at a time, and let the horses stand hitched. Between the ox stalls in the south wing, is a ten-foot passage way through which carts with roots or green feed may be driven, the stairs in the middle being hinged at the ceiling and fastened up. The stalls are seven feet wide, and arranged to tie up two cattle in each. A gutter to conduct off the urine runs along behind each range of stalls, and there are well secured traps, one in about every fifteen feet, through which the manure is dropped to the cellar. The letter C, wherever it occurs in figure 3, indicates a trap door of a- manure drop. The letter D is placed wherever there are doors which, in the engraving, might be taken for windows.
The cattle pass to the yards through doors in the ends of the wings. The south yard is nearly upon a level with the floor, sloping gradually away toward the south and east; but the large barn yard is on the level of the manure cellar, and an inclined way gives access to the yard on the east side, from the cow stalls. Three roomy, loose boxes are provided, one for horses, and two as lying-in stables for cows. Near the points marked W, and F, stands the hydrant for flowing water, and the trough for mixing feed, and here, too, the shutes for grain and cut feed discharge from the floor above.
Ventilation And Light.—Four immense ventilating trunks, four feet square, rise from the feeding floor straight to the roof. These are capped by good ventilators of the largest size, and cause a constant change of air in the stables, the draft being ordinarily sufficient to be felt like a fresh breeze, by holding the hand anywhere within a few feet of the openings. This keeps the air in the whole establishment sweeter and purer than in most dwellings. The windows on all sides of this floor are of large size, with double sashes, hung with weights.
Size Of Bars'.—The building covers more than onefifth of an acre of land, and thus there is over three-fifths of an acre under a roof. The main barn is fifty-five by eighty feet. The wings are each fifty-six feet long, the south one being thirty-five wide, and the east wing thirtyone and one-half feet wide. The four leading points sought for and obtained were: first, economy of room under a given roof, second, plenty of light, third, plenty of air, and ventilation which would draw off all deleterious gas as fast as generated, and fourth, convenience to save labor. Saving of manure, and many other things were of course included. The windows are all hung with pulleys, and are lowered in warm days in winter, and closed in cold days. This is important.
