I am getting a new old boat ( late 1930's) and I want to install a Kitchen rudder. In searching the net for info I found there is a USA patent ( no. 4895093) for a modern version of the Kitchen rudder.
My challenge is that I cannot open the image on the USA Patent Office web site. I'va asked others to try to open the Image page - to no avail. Can anyone out these open the Image?

Miro,
Yes... I have opened the images on the USA patent site... post the full url of the patent you are trying to get and I will try to open it and then save the image and email it to you.
Also... there is a full chapter on "The Kitchen Rudder" in Weston Farmer's book FROM MY OLD BOATSHOP. It has some stetches of it, but they are not dimensioned... not suitable for construction.
Regards,
Andrew |

Here's a link to the patent. Unfortunately, one cannot print it since the UPTO makes its living charging for copies. 8^(

I couldn't get to it from the link Bob provided above... that link might include a session number that timed out... but I went to the search page:
http://patft.uspto.gov/netahtml/srchnum.htm
... and entered the number: 4895093 and it worked fine.
If yours doesn't load Miro it is probably due the "QuickTime" plug-in. You could try downloading the latest one.
Interesting patent, very recent, 1990.
Regards,
Andrew |

Yes the problem was the plug in . I was able to download it from the USAPTO web site and was able to open the drawings. I wonder if these things work?

Miro, I have driven a 33ft survey launch with a "Kitchin" rudder, they give very precise control as needed for surveying around wharves and jetties |

Hi Raymond,
Do you have any photos of your launch that you could post, particularly ones showing the Kitchen Rudder?

Try Google patents- it is on the home page. You can then do a save-as on images of pages. I used to use quicktime then went to this- give it a try.

I have 1967 Luhrs 32 sedan. When I Ran it the first time backig out from the slip I realized that to make a right hand turn I would have to do 270 to the left.the stern walked to the right (left hand prop) and that was that. I installed a kitchen rudder and now I can back with complete control and also I can partial close for slow trolling. I use a 12 volt hydraulic actuator and cylinder to open and close. |

Kitchen rudder photo 1 - rudder head - lowest bracket is a horizontal vee shape and is where it would have bolted to transom so would be fixed. Whole assembly rotates above this bracket. You cannot see the vee in this shot as camera is horizontally level with the bracket
phot0 taken at Basildon Motor Boat Museum, Essex, England, sept 09.

This photo shows the same area ( tiller ) as photo one but now you are looking vertically up to the ceiling, along the main vertical axis of the assembly.
You can see the arms attached to the 2 concentric rudder shafts, which run down inside the bronze tiller casting.
you can see the actuating links, and the method of fixing to the acme thread.
Remember there is no 'boat' it rotted away a long time ago. |

TILLER AREA - thread and plaque
The plaque is the maker's plate - it says:
KITCHEN'S REVERSING RUDDER CO
LIVERPOOL
No 904
You can see the acme thread on the shaft protected by a sheath or cover with a slot in it otherwise the arms would twist.
I must admit I am not sure if there is only one continuous thread or if there are 2 threads , one left hand, one right hand.And is there one collar on the thread or two - moving in opposite directions ? I tried to operate the machanism but without the wheel on the end of the shaft I couldn't move it. I did use one of these a few times when I was in the British Royal Navy - 1975. |

Here you can see the bronze skeg, and the bottom joint of the two fabricated (riveted) sheet steel/iron buckets, both hard over to port and in the nearly full astern position, i.e closed together.
The propellor itself, and the prop shaft is missing, otherwise you would have been able to see at least part of a prop blade in this shot.
You can see the how the bottom bearing works . |

This shot shows both buckets, the skeg and the red remains of the wooden keel and hull, as well as the prop shaft aperture.
If you look closely on the right hand bucket, the horizontal white line is in fact one of the two riveted joints - the lower one.
Each bucket is made of 3 pieces, 2 curves and a straight.
If you now look closely at the left hand bucket you can see the corresponding 'step' where the joint is on that one. You can also see the top joint in this left hand bucket..all very simple - a 3 piece riveted fabrication.
I dont think the buckets will nest in each other, I think they probably but up againt each other in the fully astern ( as in photo ) or fully ahead position.
Unfortunately I did not get a very good shot of the crucial top mounting, but there is a gland, and then each bucket is on its own shaft or tube, all mounted concentrically...so you have 3 nesting layers of tube.
There is not alot to see externally, you have to guess at the workings.
The retaining nut is missing, but obviously fitted on the threaded part of the shaft where the dab of red paint is.
Again - its not clear how the middle shaft is fixed to its bucket, must be some sort of flange I think |

OK so I was lieing...here is a photo of the top of the rudder, so you now have 4 nested tubes...gland, rudder stock, one bucket, second bucket.
You can see the both buckets and the flanges joining the buckets to the shafts
the prop shaft gland is just visible lower down |

Up at the top of the rudder stock again.
View from directly astern.
Shows the 3 tubes, stock, outer bucket , inner bucket and the yokes and connecting rods - method of fixing.
And the lubricating holes - in fact this example is seized solid . |

This shows the actual tiller itself, ( the perspective is odd because it was way above me and teh camera) and the end of the screw thread spindle, where the operating wheel should be - think a small lathe type feed wheel here, with a finger sticking out as on a mill or lathe.
I have seen posted elsewhere that you needed 3 hands to operate these things - one on the tiiler handle to steer, one to wind the wheel and one to operate the throttle.
This is not the case, the engine is run at constant revs, when manouevering and all the acceleration/deceleration is done on the buckets.
if you slow the engine down when you want to stop or go astern , then you are missing the point, aswhat you are doing at all times is controlling the prop wash with the buckets - ahead, astern, neutral, and in between.
And the actual direction of the propwash is adjusted with the tiller. |

This shows the tiller itself disappearing off vertically out of the picture - it looks as if it is silver soldered on to the main casting.
...and the end of the screw thread spindle - minus it's operating wheel.
And the way in which the threaded spindle is inserted into the horizontal tiller casting and retained by a sort of gland arrangement. |

That is all the photos I have of the Kitchen rudder gear.
Please don't fall into the trap of referring to it as a KITCHENER Rudder, because its not - its named for and by the British Admiral Kitchen.
Here is a link to the website of the museum holding this exhibit, plenty of ic engines there especially outboards and 1920s-80s racing craft etc. Entry is free.

Thanks for posting this valuable stuff - I'm finally getting back to the restoration of a 1910 fantail launch ( 18ft) - you'll note my original post from many years ago - doesn't seem that long.
I like the idea of an electrically operated bucket position system, so that I only have to think about the rudder position.
I won't get this done till July / Aug next year, but this might just speed things up.
After that, maybe it would be great to take the boat to the LA bateaux-fest the following March - any excuse to get warm.
Thanks gain,

Try reading this website from a true expert, and on your side of the Atlantic too.....
http://www.proboat-digital.com/proboat/200608/?pg=63
The author of the article is David Gerr..and the web says this about him:
Dave Gerr founded Gerr Marine, Inc., in 1983. Based in New York City, the firm designs both yachts and commercial vessels, and probably works on a wider assortment of boat types than any other design office—sail and power, yacht and commercial, monohull and multihull.
In 1979, Gerr started as a naval architect at MacLear & Harris, Inc., where work concentrated on megayachts, power and sail, and where much pioneering design in large and small multihulls was done. Gerr also has built, repaired, and lofted a wide variety of boats, and has supervised FRP production on the shop floor.
In addition, Gerr performs specialized surveys for insurance companies and law offices. He has been an expert witness on a wide variety of cases, from marine-related homicides to routine insurance and damage suits.
Gerr is the author of Propeller Handbook, The Elements of Boat Strength, The Nature of Boats, and Boat Mechanical Systems Handbook, all published by International Marine/McGraw-Hill. He has written over 400 articles on boats and boat design that have appeared in almost every major boating magazine, and he has been a contributing editor for Yachting, Offshore, and Boatbuilder magazines.
A graduate of the Westlawn Institute of Marine Technology, Gerr studied physics at New York University and industrial design at Pratt Institute. A Fellow of the Royal Institution of Naval Architects (RINA), Gerr is also the director of the Westlawn Institute of Marine Technology. |

I have watched both these 'tlane0' videos - very impressive, especially the idea of having powered actuation, saves a lot of hand wheel turning at a time of maximum brain concentration. |
