The Continsouza (Delco) two cap two spark distributor of a Hispano-Suiza 6H (1919-33). It is using two Delco 14940 distributor caps, as used on 1921-22 Model 116 Single Six Packards.

Layden B Posted January 18 Share Posted January 18 Thank you Peter for the pictures. Many many years ago I was at a West Coast of US swap meet. A vender had a large array of New Old Stock Delco parts. I purchased a NOS strange 6 cylinder unit because it was interesting, unknown application to either of us, and cheap! After a couple of years of unsuccessful head scratching I walked into a restoration shop that was doing some engine work on a Hisso. Quite enlightening to learn about Delco products being used on European cars. Had no problem finding a buyer for a then identified distributor unit.

Peter R. Posted January 18 Share Posted January 18 Layden, the distributor would be worth a little fortune today….🙂🙃 While discussing two cap two spark distributors, did you ever come across one of these…? 6 cyl. two cap two spark with four points, Delco 5229.

alsfarms Posted January 18 Author Share Posted January 18 Very interesting! I didn't even know that Hall Scott produced a four cylinder aircraft engine. Do you have any particulars, bore, stroke, CID, I imagine water cooled. What type of plane was it used in? Al Link to comment Share on other sites More sharing options...
Peter R. Posted January 19 Share Posted January 19 Al, I can only tell what I found in the Delco books and that‘s not much. But I found a picture of a Hall-Scott engine in an aircraft book that shows a distributor similar to mine. I‘m not sure if it shows a 5229 as there are some more distributors that Delco made for 4 cyl. and 6 cyl. Hall-Scott aircraft and marine engines; 5191 (4 cyl.), 5217 (4 cyl.), 5227 (marine), 5230 (6 cyl.) etc. 5229 is a 6 cyl. distributor. No clue what aircraft the engine was used on.

Peter R. Posted January 19 Share Posted January 19 The Delco two cap two spark distributor service parts list incl. distributor application index for your reference. Distributors 5186, 5196 and 5213 are furnished with twist'n'lock type distributor caps, all others use clip secured caps. I can gladly look up the performance data if someone wants me to. 1 2 Link to comment Share on other sites More sharing options...

Al For Pierce autos, 1924 is shown in the books for single-cap but I've seen very original 1924s with Dual Delco. Perhaps an early/late? 1 Link to comment Share on other sites More sharing options...
alsfarms Posted January 20 Author Share Posted January 20 I must admit, I like the looks of the two cap version better but I would almost think that the later single cap version was likely less trouble and a technological advanced improvement. Al Link to comment Share on other sites More sharing options...
Peter R. Posted January 23 Share Posted January 23 When comparing the two distributors I can‘t make out any technological improvements on the single cap version. I think it was just cheaper in production as it only had one vertical shaft. So it consisted of less parts than the two cap version. But as an advantage I see the use of jump spark caps and rotors from around 1926 on (sliding contact caps and rotors wear out faster than jump spark ones). Therefore I think the single cap version was more reliable. 1 Link to comment Share on other sites More sharing options...
alsfarms Posted January 23 Author Share Posted January 23 Peter, Your assessment of the differences between the two cap and single cap versions is the thinking as I have. That said, I like the looks of the two cap unit. and if kept in good serviceable condition the two cap make a T head engine run very good and with a high degree of reliability. I have a single cap unit but have not run it yet for comparison. Al Link to comment Share on other sites More sharing options...

Peter R. Posted January 23 Share Posted January 23 BTW, unlike the two cap two spark Delco distributors, only Pierce-Arrow used the single cap two spark distributors. So they‘re Pierce only (although I put them ALF‘s 🙃). 5265 was used on all 1924-27 Series 33 Pierce-Arrows (the application index above is dated 1925). Note that the jump spark distributor cap and rotor is listed for 5265 in the service parts catalog below (1931). The pictures above show the earlier sliding contact caps and rotors. 1 Link to comment Share on other sites More sharing options...
alsfarms Posted January 23 Author Share Posted January 23 Hello Peter, Do have in your Delco parts the jump spark distributor cap and rotor for the #5265 six cylinder unit? It would be nice to make this unit complete again. Al Link to comment Share on other sites More sharing options...

Watercooled, it was apparently used in training planes. 1 Link to comment Share on other sites More sharing options...

Since the caps are hard to find and not cheap, I slightly modify the distributor housing so I can use a 1839166 cap, which is much easier to find. 1 Link to comment Share on other sites More sharing options...
