I stumbled upon similar problem. Here is my solution. Hope this will be helpful to someone out there

wss = []
class wsHandler(tornado.websocket.WebSocketHandler):
    def open(self):
        print 'Online'
        if self not in wss:
            wss.append(self)

    def on_close(self):
        print 'Offline'
        if self in wss:
            wss.remove(self)

def wsSend(message):
    for ws in wss:
        ws.write_message(message)

To send message to your websockets simply use this:

wsSend(message)

wsSend update

I've been getting exceptions with wsSend once in a while. In order to fix it I've modified code a bit to following:

def wsSend(message):
    for ws in wss:
        if not ws.ws_connection.stream.socket:
            print "Web socket does not exist anymore!!!"
            wss.remove(ws)
        else:
            ws.write_message(message)
