Many many moons ago, I bought a skid-stear loader and backhoe. The backhoe was removable from four heavy tabs on the body frame of the power unit. The loader bucket was suspended overhead while the backhoe was attached. While discussing the machinery options, i asked if the backhoe could be mounted into the loader bucket tho, not only give more versatility, but to be safer for the operator. "That has never been done" and "that sounds sort of crazy (probably meaning I was crazy)" and other such remarks either said or unsaid.
I got the machine home and called my fabricator/repairer/welder of damaged parts about my idea. He stopped by my house on his way home or to anther job and we discussed my idea. One of the things i liked about my friend, beyond his total knowledge of his trade and willingness to come out in any weather to get me back on the road ASAP, was his honesty. I was forever coming up with ideas to expand the use of any piece of machinery i had bought. He always shook his head and went into a series of remarks about my sanity, or more to the point, my lack thereof. By the time he finished his tirade, he would have taken all the measurements he needed, transferred the information to a scrap of metal from tieback of his truck or on a fender or anything he found that he knew would still be with him by time he got back home.
Withing a couple of days, he called me back with the info that he had something constructed and I should bring it to his shop. His shop was and empty spot in his back yard with room to park a machine that he might be in process of putting back together. I towed my machine down to him the next morning. I was expecting (foolish expectation) to leave my loader/backhoe with him to make fiinal measurements and fabrications. But no, we hooked up his invention/my idea to the frame of the power unit and I was off and ready to work. The whole thing went together perfectly with the first try. My friend was uncanny in the way he could design in air and with a few hours of work come up with pieces that would fit perfectly. I told him he should get patent. He was like me in that his designs were always in a large blueprint rolled out inside of his head. He told me he would not waste his time with any patent as somebody, as soon as they saw what he had done would come yup with something better any how. Within six months, a competitor to my machine came out with a backhoe mounted on the boom arms of the loader with a quick hitch arrangement far superior to what i had. Now every body who is building skids tears are mounting backhoes and all sorts of equipment on the loader arms of their machines.
I tried to show a pic, but no luck. I'm late as it is so don't have time to fiddle it out.
