Description: |
| The patent title obfuscates what is being patented. From the specification: "It is well known that milk is a mixture or compound of oil, lymph, serum, and salt, the separation of which produces butter, cheese, and whey. The serous and oleaginous parts separate after standing some time, and rise to the top in the form of cream. From this cream, put into a churn, butter is produced, by the agitation and separation of its parts. The machine, which I have invented for this purpose, and which I call my agitating and separating machine for making butter, and for other purposes where agitation or separation is required, is represented in the annexed drawings." |
