Writing a javascript library - object

Question

I want to write a JS library and handle it like this:
var c1 = Module.Class();
c1.init();
var c1 = Module.Class();
c2.init();
And of course, c1 and c2 can not share the same variables.
I think I know how to do this with objects, it would be:
var Module = {
Class = {
init = function(){
...
}
}
}
But the problem is I can't have multiple instances of Class if I write in this way.
So I'm trying to achieve the same with function, but I don't think I'm doing it right.
(function() {
var Module;
window.Module = Module = {};
function Class( i ) {
//How can "this" refer to Class instead of Module?
this.initial = i;
}
Class.prototype.execute = function() {
...
}
//Public
Module.Class = Class;
})();
I don't have a clue if it's even possible, but I accept suggestions of other way to create this module.
I don't know if it's relevant also, but I'm using jQuery inside this library.

Usage:
var c1 = Module.Class("c");
var c2 = Module.Class("a");
var n = c1.initial(); // equals 'c'
c1.initial("s");
n = c1.initial(); // equals 's'
Module Code:
(function(window) {
var Module = window.Module = {};
var Class = Module.Class = function(initial)
{
return new Module.Class.fn.init(initial);
};
Class.fn = Class.prototype = {
init: function(initial) {
this._initial = initial;
},
initial: function(v){
if (v !== undefined) {
this._initial = v;
return this;
}
return this._initial;
}
};
Class.fn.init.prototype = Class.fn;
})(window || this);
This is using the JavaScript "Module" Design Pattern; which is the same design pattern used by JavaScript libraries such as jQuery.
Here's a nice tutorial on the "Module" pattern:
