Stationary Baler: Engineering and Evidence
Our friend, Mark Schwarzburg came by the office with an old wooden box he inherited from his great great great grandfather, Henry Schwarzburg. In it is a lovely, very old working wooden model of the stationary baler Henry helped to invent. Also were found, on old oil-skin paper, beautiful original engineer’s drawings for patent registry; and a brochure for the actual resulting manufactured implement. I just knew some of you would get as excited as I did seeing this material and feeling the history of it all. Thanks to Mark’s sharing we can enjoy and wonder… LRM
DESCRIPTION OF THE NOXALL No. 1
This is a full circle, double-stroke perpetual baling chamber; it is mounted on four wooden wheels thirty inches high (except the hind wheels under the all-steel press, which are thirty-six inches high). Its workings are simple and durable; no platform for the team to climb over; no chains or cable, not even a link. The power is composed of a variable S-shaped gear, and is constructed that it gives the plunger two strokes to the round of the team. There is not a spring, trip-dog or unshipping point about it. The power gears and connection with the compound levers are so arranged that the power moves fast at the beginning of each stroke, when the material us loose, but as the density of the charge increase the power compounds proportionately until the center is reached.
The sweep is twelve feet long, and in passing over the center there is no jerk whatever on the team; therefore it needs neither tongue nor neck yoke to prevent the sweep from crowing the team. It is fed from the top with a fork, and has no doors to open and shut. The pressing chamber is fitted with retainer hooks to prevent the hay from springing back into the pressing chamber.
Owing to the particular shaped gears, it has five points where the power is increased, which equalizes the draft and makes it light on the team. It is easily set for operation, or put in shape for moving. Three men and a team are required to do the work; the team is tied to the lead pole, which they will follow round in a circle – usually without a driver – but a seat is furnished with each press, in case a boy should be needed to drive.
IT HAS A POSITIVE MOTION FOR DRAWING THE BEATER BACK
Any one who has operated a press that depended on the expansion of the material, springs, weights or other devices to bring the beater back, need not be told how uncertain they are. We will admit that they will bring it back the majority of times; but it is the times that they fail which causes so much annoyance and delay. With the Noxall the operator will not be annoyed by the beater not coming back, for it is pulled back by the team, and so long as they travel the beater must make regular back and forward motions, whether there is hay in the press or not. This makes it very convenient to prime the press, and also enables the operator to make a loose pressed bale. It is only in case it does not rebound that it is pulled back by the team.
