1894 Otto Engine at Brazil

[Spock]

This engine is a property of the School of Engineering of the UFRGS (Federal University of Rio Grande do Sul) by more than 100 years. 15 years ago, it was found abandoned in a bilge and was completely restored by engineering students and it is part today of the of the Museum of the Engine, kept for the students.

This engine was originally used to generate power for academic studies.

The 5 HP Otto in Brasil serial number 14239 was not manufactured until late 1912 or 1913. The confusion comes from the 1894 patent plate that is on most all Philadelphia Otto engines. I believe I had gotten an email from the university several years ago and replied to it but never had any more replies due to the language barrier. I would suggest that the picture of the testing room on the university website link shows the Otto when new working along side a Gray engine and another unidentified vertical. The picture caption suggests 1912 and that is probably accurate. Many Otto engines were shipped overseas to unnamed destinations just listed on the shipping papers as being delivered to a freight broker or ship in NYC. Serial # 16026 was the last engine made. About 1894 they were making engines in the 4000 serial number range. Otto engines in Philadelphia were built in lots or groups of 5 to 75 engines per size range with the average lot size being 25 engines. Serial numbers were served up in consecutive blocks and about 10 percent were either never used or sometimes an earlier engine was factory rebuilt and issued a new serial number.

5 O cavalo-força Otto no número de série 14239 de Brasil não era manufactured até 1912 ou 1913 atrasado. A confusão vem da placa de 1894 patentes que está em a maioria todos os de motores de Filadélfia Otto. Eu acredito que eu tinha começado um email da universidade diversos anos há e lhe tinha respondido mas nunca tive any.more respostas devido à barreira de língua. Eu sugeriria que o retrato do quarto testando na ligação do website da universidade mostra o Otto quando funcionamento novo ao longo do lado um motor cinzento e um outro vertical não identificado. O subtítulo do retrato sugere que 1912 e aquele são provavelmente exatos. Muitos motores de Otto foram enviados no ultramar aos destinos unnamed alistados apenas nos papéis do transporte como sendo entregado a um corretor ou a um navio do frete em NYC. De série # 16026 eram o último motor feito. Aproximadamente 1894 faziam os motores na escala do número 4000 de série. Os motores de Otto em Filadélfia foram construídos nos lotes ou nos grupos de 5 a 75 motores por a escala do tamanho com o tamanho médio do lote que é 25 motores. Os números de série foram servidos acima em blocos consecutivos e aproximadamente 10 por cento ou foram usados nunca ou às vezes um motor mais adiantado era fábrica reconstruída e emitia um número de série novo.

But there is another plate with many dates indicating the patents and a final date, in prominence: 11 of September of 1894.
There is registers of existence of this engine in the university before 1910.

I can send a pic of this plate for you.

On this site you can find a 1910's picture of Otto:

How we can determinate the exact date of construction for our Otto if the date of plate do not indicate the real date of manufacture?

thank you
