There are two big Lathrop T-Head engines for sale on the classifieds, located in Oregon.
Richard Durgee, you might want to contact him for the serial numbers if you haven't already... I just noticed that he has the serial numbers listed in the ad:
Four Cylinder S-40 NO.13579 40HP
Six Cylinder (1925) NO.6632 65HP
Also if someone has George King's (at Mystic Seaport) email (I can't find it at the moment) they might want to alert him to this...
See Antique inboard classified

LATHROP 40 HP ENGINE, C. 1926, AUXILIARY DRIVE?
Anyone know how this Lathrop 40-HP T-Head could be used to drive another device -- in addition to it's primary role of turning the prop? In particular, running a wire hawser winch, which is situated directly above the engine, on deck of a 77 foot schooner.
I am modeling (at 1:48 scale) the deck winch, which I am 'reconstructing' from partial photographic views -- and of course, the schooner herself, but the connection between the winch and the Lathrop is a mystery.
Suggestions most welcome.
The vessel is the Canadian schooner yacht CHANCE, c. 1926, which had a 40HP Lathrop powerplant.
PLEASE REPLY DIRECTLY TO MY EMAIL IN ADDITION TO THE POST.
THANKS! |

Randy, Lately i've been having trouble remembering things too!
last june 24 you asked this question and I posted a lathrop illustration of their 4 jaw hauling clutch. Since then I have found this even better
illustration, hope its helpful.
Been out of town for a week, lets see if
I can remember how to post the pictures??

Richard,
Many thanks, once again!
This is a great illustration.
It confirms my 'design' in that I have a chain drive from the knock-in clutch sprocket (now that I know what to call it) with said chain passing upward at an angle through an opening in the deck, and to another identically sized sprocket. That 'small' sprocket is in a gear box/clutch housing on the horizontally mounted drive shaft under the warping drum, with the aft end of that axle connected to a similar sized sprocket. That lower sprocket is attached by chain to a 'larger' sprocket above(about 24" diam) that shares an axle with the warping drum for the wire hawser. The winch/warping drum is oriented on the port side of the deck, again, just above the Lathrop in the engine room, and the wire hawser passes through a vertical fairleader as it comes on/off the drum and over/from the port side of the schooner.
From the partial on-deck photo I have (which shows only part of the large chain-drive sprocket, the warping drum with wire hawser on it, the vertical fairleader, and a long handle, I am concluding that the long handle is for a separate clutch actuation of the winch. In other words, to operate this thing, one would start the engine, engage the clutch for the auxiliary stuff in the hold, and then engage the winch to rotate using the separate clutch on deck.
I'm not an engineer, so I may have this all wrong, but it seems plausible...
Not expecting any kind of detailed reply, as no doubt you are busy, but thanks for the opportunity to think this through 'out loud'
Thanks again! |
