All my Schebler model D carburetors display the words PAT OCT 14 1902. I am only able to use the Google patent search feature by first entering the patent number.
I am interested in reading the original Schebler patent. Does anyone have knowledge of the patent number?
thanks

Barry,
This is the only patent I could find for your Schebler. (#711,005) Oct 14, 1902. I believe it's the same one JB is showing you.When you are at the google patent search click on the advanced search and you can search by date or what ever you want. Try spelling carburetor...carbureter and you will find a few more patents. |

John and J B,
Many thanks for the information. Patent 711,005 is the original Schebler patent and the one that interests me.
I have been using the US patent office at http://www.uspto.gov/main/patents.htm to search patents. I use this often as I find old patents a rich source of information and understanding. Patents issued prior to 1976 are very difficult to find without the patent number. Google solves this problem.
The new Google patent search engine for sure is much more effective to locate and review old patents. One limitation is only the patent drawings can be printed. I believe this is established by the US patent office to control the distribution of patents. However a full copy of a patent can be easily purchased on line from the US patent office at $3.00 through the above URL. The patent is then delivered as a pdf email attachment usually within an hour after ordering.
I have just purchased the Schebler patent as well as several Kingston patents from the same era that I found using the new Google patent search feature.
The Google patent search feature is not available to me using my Google.ca site. As I am in Canada, when I enter Google.com, I get Google.ca. Maybe others also experience this difficulty. However I am now able to get the Google patent search directly without going through Google.com at http://www.google.com/patents.
Again, many thanks for your replies and also to Paul Gray for finding the Google patent search engine and sharing this valuable discovery.

Barry,
You should be able once you have found the patent you are looking for go back to the US patent office type in number bring up patent then print it out. Thats what I do and it prints out the whole patent. This is on all the early patents. |

All my Schebler model D carburetors have the words PAT OCT 14 1902 cast into throttle plate housing. Several carbs are obviously knock offs. (As documented by Richard Day) Nevertheless the patent inscription remains although the patent expired in 1919. JB Castagnos and John Davis directed me to US Patent number 711005, the Oct 14 1902 issue.
I purchased a copy to satisfy my curiosity.
The spherical shape of the bowl is the substance of this patent as it establishes the nozzle at the same location relative to fuel in the bowl when the vehicle (or boat)
changes position due to road inequalities (or wave action).
I wonder how all the carburetors manufactured with square bowls dealt with this problem.

Is there any interest in a Gray Marine one lung engine. It has 1902 on the flywheel |
