Figure 7.—Babcock butterfat tester, about 1895. (Catalog No. 68.)
[68.] Babcock Butterfat Tester, about 1895. USNM 173353; 1946. A machine used in determining the amount of butterfat in milk or cream. The Vermont Farm Machine Company of Bellows Falls, Vermont, made the centrifuge, which mixed sulphuric acid with the milk in order to produce a reading of the amount of butterfat tested. The Brighton Farm at Patuxent River, Montgomery County, Maryland, used this machine around 1895. Stephen M. Babcock developed this tester in 1890 and released it to the public, without patent, in 1891. The device had far-reaching effects in the dairy industry, because for the first time it allowed accurate payment to farmers for the actual amount of butterfat in their milk; also, it allowed farmers to test their cows to discover which ones produced the most butterfat. Gift of Sidney S. Stabler, Hyattsville, Maryland.
[69.] Buggy Rake, 1840. USNM 175393; 1947. The buggy rake harvested grain after it had been cut with a cradle. The rake has handles and a wheel, like a wheelbarrow, with long wooden tines in front to scoop up the grain. When the binder stepped on a bar at the back of the buggy the tines would move up and allow the grain to slide back against the uprights in a convenient position for binding. Although it undoubtedly reduced the physical labor of binding, this rake would not have been very efficient and would have allowed the reaper to get far ahead of the binder. Gift of F. B. Day, Owosso, Michigan.
