Il 31 luglio 1841 William Ward Andrews brevettò a Londra questa splendida apparecchiatura per ottenere un caffè più corposo.
Sollevando lo stantuffo si aspirava l'acqua obbligandola a passare a forza attraverso il filtro contenente il caffè macinato.
Premendo sullo stantuffo si forzava il caffè a ripassare attraverso il fitro.
Con una ventina di pompate ritengo potevate essere soddisfatti.
Almeno all'epoca...
Sul libro del sig. Bramah la potrete ammirare in tutto il suo splendore!

Macchina a pressione con il vuoto.
Bella recuperazione del sig Ward!

grazie Andrea!
RispondiEliminaWell, I think the very first french patent for this type of coffee-pot is not from Tiesset but from John WHITEHEAD from Brougton (near London), deposited on 22/03/1840, delivered 18/06/840.
RispondiEliminaAnyway, the very first to propose this principle was Elard RÖMERSHAUSEN in 1818.
Cheers,
Thank you so much!
EliminaAnd I forgot to thank you Lucio for your marvelous source of information !
RispondiEliminaA pleasure...
Just to be precise... now that I realize that I was misled by the first comment and that I'm not fluent in italian ;-) :
RispondiEliminathe pump in the Andrews coffee pot is used to directly push the water through the coffee whereas is Römershausen, Whitehead and Tiesset inventions, the pump is used to create a vacuum that force the water to pass through the grounded coffee. That's not exactly the same principle, my appologies.
This considered, Römershausen seems to be the first to porpose this principle also (on a large-scale machine), in 1821.
Hello
RispondiElimina1816 The first was "Comte Réal" for depression and the pressure of a water column . The beginning of the pharmacy ...
Römershausen, Rabaut Loysel,Caliman etc. .. are not creative inventors of a new application is assemblers / perfectionneurs and filing patents away from the original inventor country.
Ciao
Andrea
lucky french friends... your patent office works! I wish, one day in Italy... will be the same.
EliminaNo chance that will ever happen, dear Lucio! I hate the word "Never" but in this occasion, i am afraid... What do we learn? Our knowledge is restricted by the documents we can find, and extrapolation is misguiding. Is the patent owner, the inventor? (see R.Radaelli - P- Buffa) Did it get patented (or not) because that person could afford it (or not)? The first inventor... until we find an earlier patent. I am much more careful now that i was 4 years ago. If someone registers an invention abroad doesn't automatically means they were enemies, it could also mean the 2 patent holders were business partners... and with patent procedures lasting longer than others in the different countries... it would be a mistake to think that one was "first". How much was the access/knowledge of a patent holder regarding former inventions? Also, Maybe different inventors had the same idea in different countries, maybe a week, a year, a decade later. We have internet now. We can see patents online. How was it in 1816??? Anyway, i like to think they are millions and millions of different greys... and only one white and one black. Ciao Lucio!!!
Eliminathanks Miki! :-)
EliminaCiao Mike e Lucio
RispondiEliminaImagjnate un mondo sconosciuto e dunque nessuna informazione e visibile. Chi vuole altra cosa che la logica tradizionale per avere la fede di credere a l'impossibile e andare lo cerca...
Apri la porta di una stanza dove chi sta quatro muri nudi (le limite de la nostra logica propria )e la reflexione sul la metoda di andare cerca l'informazione "tout azimut"ti puole porta molto lontano e le informazione arivano di fonte molte diverse.
.Non solo brevetti che informono e puo essere molte piu vie d'informazione précise che il "extrapolation" dietro il silenzo de le date,nome di un scan di brevetto ,Ma...l'humano e capabile di acetta un altra logica oltre di quello che conosce?

I just would like to add this: to the knowledge i have, coffee travelled from east Africa, through north Africa, the Arab Peninsula, Turkey, Eastern Europe, central Europe to arrive to West Europe. I always hear of Germany, France, England. Has anyone checked the patent offices in Ethiopia, Yemen, Turkey, Bulgaria, Greece, Serbia, Hungary... etc. etc. etc. etc. etc. (and etc. i mean the czech republic, Moldavia, Poland ... all countries that didn't exist at the time) ? Please don't tell me you haven't.
EliminaI had started to formulate a long answer ... but i realised i must be a poor researcher, because i have problems to make a full puzzle with pieces given to me by the first generation (sons and/or daughters) that was born from the 6 original inventors/manufacturers. And you are writing a story that dates back to 8!!!!! generations!!! (without contacting the families i suppose). I heard MANY MANY times sentences from these sons and daughters that started with "i think i remember that my father told me" about facts that happened 10 years before their birth. To really grasp what i mean: Ask yourself what your father did 10 years before your came to this world! My point of view is that - and i say that because i lived it - it is better sometimes to be extra cautious, not fall into the trap of logic ;.) ... and to admit that some events don't really make sense, or don't reflect what really happened at the time... and that's completely alright.
RispondiEliminaImagine Robbiati is suing Tarditi (example)
RispondiEliminaCourt both inventors must produce evidence of the novelty of the invention relative to the date of patent inventions that were filed before to prove that their patent is a real novelty .
Imagine having the expert report of this time during the trial that explains that this invention is not new or is in providing evidence (giving also other information on other patents ..) )
Even if the expert of that time may be unaware that a Hungarian in his workshop first to invent this principle, this report gives you a snapshot of the legal time without lies in court.
Most important to profile a time not knowing that perhaps there is an inventor who creates the invention before another and so we do not speak of two because it can have a third or Moreover, if we do nothing and cry that the odds are too numerous .
The trap is to believe that we know all our personal logic ok , but to be negative about equally by the precautionary principle is the same.
It is the same for your great research Robbiati, Stern etc ... Even with all your work in the background of the background, I can tell everything is false because there are other inventors without providing the evidence and put you in a position to justify yourself again and again just as a precaution "maybee"i broken your bigest work?
Andrea
oh.. I have a dejavù.
EliminaAndrea, Mik , do you know each other? have you ever speak in french directly? this would help.
This is a "funny blog", where seriousness is not appreciate.
You have good ideas, and lot of experience, but different point of view of the same reality.
Next step is well known, but I would not to see it. No fight please, only kind opinions and love for what we would love to believe.
History is always far from reality, ask to your mother to describe facts you remember very well: 2 different stories.
Yes Lucio, we already wrote to each other in French. Maybe it would help if my Blog was written in french. I have nothing to prove. (so i don't know yet how you can tell me everything is false). I am just presenting the results of my research. This is it. Sometimes, facts do make sense (Mr. Robbiati and Mr Stern were business partners). Sometimes, they don't (Rights for the patent sold to Hungarians before the creation of Brevetti Robbiati, or Mr. Stern registering internationally the trademark "Atomic" in 1950)... and that's it. Sometimes they remain so for 4 years, until i find another document that brings light into the half-shadow. Sometimes, a relatives remembers something and that is fine too... sometimes it don't fit to the documents either. This is life. No worries Andrea, you can't break my biggest work... that's all the personal experiences i made on the way. You can judge it if you want, but you won't take it away. By the way, "Maybe" is not precaution, it's humility. It is admitting that i know nothing... Ciao!
EliminaBonjour Lucio
RispondiEliminaLe Français est une langue diplomatique pleine de subtilité ou se croisent les idées et les passions.
Entre les mots et phrases se glisse le plaisir d'apprécier la personne dans la discussion en face de toi:et cela Lucio pour le comprendre traduit en Anglais pour quelqu'un qui n'a pas notre culture,c'est impossible.
Pour le coté marrant de ton blog oui tu a raison et j'espère que tu va continuer à poster!!!
Andrea.
.
Tout à fait raison. Rien à redire! Allez Lucio, continue à nous faire rêver!
RispondiEliminaI love you guys!
