Lewis D Bunce Patent

Monday, 30 May 2011 | by Mark Tucker

I recently learned from my cousin, Carol, that  my 2nd Great Grandfather, Lewis DeMott Bunce (1827-1894), received a patent for improvements to the butter churn.


Inventor: Lewis D Bunce

Invention: Churn (improvements)

Patent No.: 337, 238

Patented: Mar. 2, 1886

Short extract from the patent:

My invention relates to the improvement in churns, the object of the same being to provide a churn in which the dasher and dasher-operating mechanism, either or both, can be readily removed from the churn body when it is desired to cleanse the parts or remove the butter.

A further object is to provide a churn in which the motion of the cream while being agitated will be steady and regular, which will permit a section of the cover to be left off while churning without danger of throwing a portion of cream out of the churn.

A further object is to provide a churn with side wings and dasher adapted to be adjusted vertically to accommodate them to varying quantities of cream in the churn.


It is exciting to see that one of my ancestors was an inventor.

Let me know if you have an ancestor that was an inventor or received a patent.

  2. My ancestor Peter Hoogerzeil (1841 – 1908) had over a dozen patents. I’ve blogged about him twice at and at I think that researching his different patents and inventions has helped me to see him more as a real person, and not just another name with dates.
