To the stamp motives:
- 10 (Pfennig): "Bockdampfmaschine" from the firm ""Kamm- und Wollspinnerei Morand & Co.", Gera (Thuringia), 1833
Note:
Stationery "trestle steam engines" (trestle = "Bock-") were relatively widespread in the time of about 1830-1865.
At these the cylinder stands to level earth. The flywheel and the crankshaft will be carried in trestles (= "Böcke")
stored again by columns. The straight guidance of the piston rod occurs about a wide crosshead. The speed was often
regulated about a centrifugal force governor (= "Fliehkraftregler"). Moreover, a food water pump to the kettle supplied with fresh water.
- 85 (Pfennig) : "Balancier-Dampfmaschine" from Freiberg (Saxony), 1848
