And the farther the bin is from the window, the shallower the angle for the shute. Get it too shallow and the coal will back up in the shute and overflow onto the floor and/or outside on the ground !
And allow enough depth below the window for the top of where you want the coal mound to finish up for the amount of coal you wish to store. The coal piles up in a mound under the end of the shute and once that mound top reaches the coal shute, the coal doesn't flow down the sides of the mound. Then it backs up in the shute unless someone is down at the bin pushing/raking it into the corners (which I have to do now).
For instance, if you want a bin that holds say 6 tons and is chute fed through a basement window, . . a bin 5 feet wide, 8 feet long, and 6 feet deep will hold that. But, if the bottom of the window is at 6 feet, you can't fill that bin with 6 tons from a shute.
You'd need a window about 8 feet off the floor to shute 6 tons into that size bin. So, build the bin wider (which I'm doing this summer) so that there's at least two feet below the end of the shute for the cubed volume of coal. An 8 x8 bin only needs to be 3-3/4 feet high to fit 6 tons and that gives more than a 2 foot drop for the coal to flow into a mound ending at 6 feet under the shute.
I'm widening my bin by removing a couple of boards from the right side wall, then adding another 6 feet width of bin space to that side. That will give me a total bin space of 8 x 11 x 6 feet high, with that lowered right wall dividing the new bin into two, connected bins so that I can use up one bin to clean out the fines as I work from the other half.
And, by angling the shute as it comes through the window so that it's end is above the lowered right side wall, it will fill both sides. Or, by shifting the angle of the shute, I can put nut coal on one side and stove coal on the other. Both can be delivered through the same window.
