Joseph Day was the English inventor / patent holder of the Three port 2 cycle engine. This is a December 1905 notice in Motor Boat Magazine as to the Companies that had bought the rights to mfgr engines with his three port design .

As I recall the US. Patent ran out in 1907. Didn't do Mr. Day much good in the US. As far as I know there is no connection between his Day family and mine. |

Thanks for the update Richard. I remembered reading that same article too many years ago so forgive my fuzzy date. It is curious that the Palmer Model Q came on stream in 1905 and in the 1907 catalog it shows the Q as a two port engine but titled as a 3 port. The change to a three port took place by changing the cylinder and using up the old two port bases by not providing the threaded boss for the check valve into the crankcase. I have one of those bases unfortunately badly abused by an amatuer welder I suspect. I also have a 1916 Q-1 where the boss is no longer present on the upper half of the crankcase. |

Richard,
Thanks for providing this information. After reading your post, I rushed to purchase a copy of US patent 544,210. As you already discovered, Frederic Cock was the inventor and obtained British patent 18513 in 1892. The US patent was assigned to Joseph Day. I suspect Day was a capitalist and entrepeneur.
The patent is just four pages, two pages text, and two drawings. It is difficult to compress these to less than the 50k threshold and attach to this post and maintain readability so if you wish I will email the PDF files to you, should you not already have a copy. Page 2 is less than one half page of text and contains the two claims. The claims are the most important part of the patent as they set out what the inventor believes was unique and not previously used by others. I am including page 2 with this post.
Note that both Cocks’ claims require that in addition to the usual and expected three port features, a separate air inlet port and gas inlet port are required. The drawings illustrate the two ports at equal vertical and horizontal dimension although this configuration is not included in the claims, only is the presence of separate ports.
I wonder whether there are examples of three port engines from the period prior to 1907 that make use of separate ports for air and fuel entry, particularly engines manufactured by the Companies listed in the December 1905 Notice in Motor Boat Magazine, who apparently accepted the patent terms.
Or perhaps Day was just a great salesman!!
I have also attempted to obtain a copy of the Schebler carburetor patent, as evidenced by the 1905 “cast in bronze” proclamation. Do you have a copy of this patent, or perhaps a patent number.
Regards
Barry

Welcome aboard !
My initial info on the history of the 3 port engine was in an Engish publication "The Gas and Oil Engine" by the prominent engineer, chemist, engine inventor,patent holder and writer Dugald Clerk. This was his 6th edition and was printed
in 1902. He refers to the Day engine so J. Day must have had a very early involvment in the developement of the engine from the original design ?
This is from the book
I would appreciate a copy of the original patent to compare with Clerks description.
Since reading of the patent in 1892 it has had my interest as to what was the earliest N.American
marine engine mfgr to use this design ?
It seems that several mfgrs were quietly mfgring the 3 port engs and others were gearing up to change over by 1905-06. Mfgs Catalogs in 1906 and later refered to their new improved 3 port designed engines.
Dick Day may have some early history of Palmer on the subject ?
An early 3 port in my collection is this 1898-1903 lackawanna Marine ( it was deaccessioned or sold off by the Ford Museum in the 1990's) one of the Companies that had been making 3 port engs long enough that J Day could probably prove in court had encroached his patent ? The other mentioned co.'s may have had the same problem ?
As to the early engs with 3 actual external ports
I'll have to look into that ? - Maybe some readers here can help ??
Schebler patent number I will look for !
Thanks for post ! |

Richard D,
Re you earlier question-I think Elmore Mfg. Ltd is the maker of the Elmore motor car. |

Thanks for post !
It interests me that Joseph Day had listed Elmore in with all other Marine eng mfgrs in a boating Magazine ad , makes me wonder if Elmore made a few Marine engs ?? |

After the May discussion above I found this article and another That Established the " Day INVENTIONS COMPANY" October 1905.
Joseph Day's partner Thomas Fleming Day was a first cousin, He was a noted sailor /Yachtsman, poet, writer and editor of The Rudder Magazine at the turn of the century. In 1912 he designed a double ended power boat and went from New York to St Petersburg Russia and came home to the U.S. and wrote a book of the adventure "THE VOYAGE OF THE DETROIT"
Would like to know if this Day Engine Co.
ever mfgd any engines ??
October 1905
