It was Montgomery [Alabama] that was hell, so I was in Montgomery in 1950. I was fifteen, and I was in Montgomery; I remember Montgomery--pretty rough place, but anyway (laughter).$$Okay. Did you have--was that the first time you'd been down south like that, in Montgomery, in those days?$$No. At first I was a little kid; I, I used to go with my mother [Fannie Scott Knott] and my two sisters [Patricia Knott and Sylvia Knott Simmons]; we'd go visit my [maternal] grandmother [Lula Allen Scott] in the summertime, so that was interesting. We'd get--we--my father [A. Paul Knott, Sr.] put us on a train in Pittsburgh [Pennsylvania], and we'd go to Cincinnati [Ohio], then we'd get on a train in Cincinnati, and the train would go across the Ohio River, and it would stop halfway over on the Ohio River going across into Kentucky, because all the black people had to go to the black car, which was not air conditioned, and I can remember that ride in that car. It was terribly hot in the summertime--no air conditioning, nothing, and they'd have the windows open and dust would be flying in there. And what my mother used to do is always pack us lunches in shoe boxes, and so we'd eat and--because she refused that we--that she was subjected to eating in the dining car, because in the dining car, they had a green cloth where blacks would sit in the corner, and they'd pull this green curtain around 'em. I don't know you ever heard of that, but I, I mean I even remember the color of it; it was green. They'd pull a green curtain. Have you heard, have you heard of that (simultaneous)?$$(Simultaneous) And you'd be separated. I've, I've heard similar things, yeah.$$Yes, and pull that little green curtain around you (laughter). And my mother would never go for that, and then we'd be so thirsty because in those days, you didn't have cans of Coke [Coca-Cola], or a bottle of Coke, or something that you could carry with you, and there was no ice. So, the, the guys on the train that would serve us sandwiches and drinks, they were called butcher boys, and the butcher boys would get on one stop, and then get off on the other, and they'd bring their stuff. And the butcher boys--it was like, I don't know, I guess equivalent to Kool Aid nowadays; it was this red punch they'd mix up, but they'd mix it in the sink in the bathroom (laughter).$$In a train (laughter)?$$Yeah (laughter), 'cause we'd be sitting across from the bathroom, and we'd watch--'cause I--when you're kids, we want something to drink. My mother would say no. She'd have a thermos bottle, you know, but that wouldn't last very long and--'cause you had thermos bottles in those days, but then the butcher boy would be mixing stuff up in the sink and then dip it out into us, to us, then they go throughout the car selling to the black people (laughter).$$In the bathroom sink.$$In the bathroom sink, yeah. Now, I, I remember that's--that happened. But see, I don't know how many times we traveled to Chattanooga [Tennessee], but it's been far more than one time in the summertime since, you know, I was five, six--four, five, six years old going down there.$Well, tell us about your invention. You invented a--well, this is one invention I know about; there may be more, but the Knott Lock.$$Well, it may seem kind of funny (laughter). I've always just done a lot of things, and one of the, one of the things I, I would say, I'm a pretty good mechanic, well, working on these boats at all times, and I'm a good diesel mechanic and a good mechanic, and I've had several cars stolen so I just thought of this and--this lock, and also working with some fellows that had developed--did various kinds of locks, then I developed this one and got a patent on it. Which, it's just a brick-locking device and also there's a starter-interrupt switch, so when you turn the key to lock the, lock the brakes, it interrupts the starter so you can't start it. If you can't start it, you can't move it; you can't move it anyways because the brakes are locked.$$Right.$$Only thing you do is lift it up.$$That's unusual that most of these devices lock the steering wheel now, right?$$Yeah.$$I've seen--we've seen The Club that they advertise.$$Well, yeah, well this, this beat The Club. I mean The Club, The Club--most of--you can't show me a Club I can't get off. So whether you manipulate--either that or you cut it, or cut the steering wheel, so The Club is no big deal. The Knott Lock, as I call it, you can get it off, but it's so time consuming and hard and you need a blowtorch and--to really get it off. People would pass up on it and go to something else that's easier to steal. But why it wasn't a success--actually, outside of the country--you got it into Australia and Germany. It was pretty successful over there because--but here in the United States, everybody was already tuned into the, the chirp like when you--electronically you would lock your doors and you hear that beep, beep, beep, beep, and everybody was--every housewife--everybody was tuned into that, so that's what killed us there. That, that just made it very difficult to--and the price we had to sell it to make any profit out of it, it was difficult to do it here because of the, the competition of an electronic device which was nowhere near and protecting your car that the--that our lock would.$$Did you still some of 'em available? Are they--$$Yeah.$$Do you still sell any of 'em?$$No, no, no.$$Okay, all right.$$We have some available, yeah.$$Okay.$$Yeah, I got some in storage, yeah.$$Okay.$$It's the kind of thing, you say, "Well, maybe someday." Oh, I, I tried to sell it and we went to car manufacturers and all, but the truth of the matter, what I found out, believe it or not, they didn't want anything like that because you couldn't steal a car, and that would help their sales and also help their repair--I mean getting, getting their cars repaired and restored afterwards, yeah, so--no (simultaneous)--$$(Simultaneous) Sounds like the Tucker situation or something, you know.$$Yeah, like the Tucker car [Tucker 48], yeah, same thing, yeah. That's big business--United States, and that's big business; that's the way things work. So, they, they didn't want--I mean even to incorporate--they could have very inexpensively incorporated it into their cars--in the manufacturing (simultaneous)--$$(Simultaneous) As a design for the--yeah.$$Yeah, yeah in, in terms of when they manufacture it, because the key chips and everything today that you have, they could be defeated. Any of these electronic locks I can show you how to defeat in less than a minute.$$Okay. So, that venture lasted from the early '90s [1990s] until--$$Yeah, that was several years--around, around 1990, yeah.$$Okay. Do you have any other--have you invented anything else?$$Yeah, I never got a patent on it. I'm just thinking. One was--back in the early '60s [1960s], which they do it a lot now, and somebody else, I'm sure, has got the patent on it 'cause they do it a lot now, was putting--taking an electrocardiogram in back of the heart by putting electrode down into the esophagus--esophageal electrode. I was the first to do that; that was back in the early '60s [1960s]. I published that. But no, I'd say I've only got one patent.$$Okay (simultaneous).$$(Simultaneous) And this other stuff, just creative stuff. I was always the kind of guy that always just liked to do a lot of things; I mean a lot of different kind of things, not satisfied to do one thing.
