Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
309 words
A device for producing a stream of air with or without vapor therein, comprising a duct for directing a stream of air in a given direction and electrical blower means communicating with said duct for blowing a stream of air therethrough, said duct being formed with an opening, vapor-generating means located next to said duct and communicating through said opening thereof with the interior of said duct for generating vapor to be carried in the air stream which flows through said duct, said vaporgenerating means having an electrical heater means, and electrical circuit means electrically connected with said electrical heater means and with said electrical blower means and including a pair of switch means accessible to the operator for selectively turning said heater means and blower means on and off, respectively, whereby said heater means and blower means may be operated separately from each other or simultaneously, said vapor-generating means including a container for liquid to be converted into a vapor by said heater means, said container having a top filling opening normally registering with said duct opening for directing vapor therethrough into a stream of air in said duct, and mounting means mounting said container of said vapor-generating means at said duct with said filling opening registering with said duct opening, said mounting means carrying a pair of circuit contacts of said electrical circuit means and said heater means including a pair of heater contacts normally engaging said circuit contacts, respectively, for connecting said heater means into said electrical circuit means, said mounting means mounting said container of said vapor-generating means at said duct in a manner compelling said heater contacts to be separated from said circuit contacts when said container is displaced away from said duct to render said filling opening accessible for introducing into said container liquid to be converted into vapor by said heater means.
Claim 2
Independent Claim
309 words
A device for producing a stream of air with or without vapor therein, comprising a duct for directing a stream of air in a given direction and electrical blower means communicating with said duct for blowing a stream of air therethrough, said duct being formed with an opening, vapor-generating means located next to said duct and communicating through said opening thereof with the interior of said duct for generating vapor to be carried in the air stream which flows through said duct, said vaporgenerating means having an electrical heater means, and electrical circuit means electrically connected with said electrical heater means and with said electrical blower means and including a pair of switch means accessible to the operator for selectively turning said heater means and blower means on and off, respectively, whereby said heater means and blower means may be operated separately from each other or simultaneously, said vapor-generating means including a container for liquid to be converted into a vapor by said heater means, said container having a top filling opening normally registering with said duct opening for directing vapor therethrough into a stream of air in said duct, and mounting means mounting said container of said vapor-generating means at said duct with said filling opening registering with said duct opening, said mounting means carrying a pair of circuit contacts of said electrical circuit means and said heater means including a pair of heater contacts normally engaging said circuit contacts, respectively, for connecting said heater means into said electrical circuit means, said mounting means mounting said container of said vapor-generating means at said duct in a manner compelling said heater contacts to be separated from said circuit contacts when said container is displaced away from said duct to render said filling opening accessible for introducing into said container liquid to be converted into vapor by said heater means.
Claim 3
Dependent Claim
27 words
The combination of claim 1 and wherein said heater contacts are in the form of substantially U-shaped springy metallic elements which normally press against said circuit contacts.
Claim 4
Dependent Claim
29 words
The combination of claim 1 and wherein said heater contacts are in the form of prongs while said circuit contacts form part of a plug which receives said prongs.
Claim 5
Dependent Claim
55 words
The combination of claim 1 and wherein said mounting means includes a support component fixed to said duct and hingedly connected to said container for compelling the latter to be turned away from said support component to render said filling opening accessible while at the same time separating said heater contacts from said circuit contacts.
Claim 6
Dependent Claim
53 words
The combination of claim 1 and wherein said mounting means includes a bracket carrying said circuit contacts and supporting said container in a manner compelling the latter To be shifted away from said bracket to render said filling opening accessible while simultaneously compelling said heater contacts to be separated from said circuit contacts.
