Reconstruction
On October 26, 1852, the United States granted Francis Wolle Patent No. 9,355 for a “Machine for Making Bags of Paper.” The patent identifies Wolle as a resident of Bethlehem, Pennsylvania—not Springfield, Massachusetts—and protects machinery rather than the paper bag as an object. Paper had already served as wrapping material, but Wolle proposed coordinating the operations needed to turn a roll of paper into completed bags with much less manual handling.
The patent drawings and specification provide unusually detailed direct evidence. Intermittently moving cylinders drew a measured length from a paper roll. Shears cut the sheet and removed a section that left material for an overlapping seam. Mechanical creasers and folders shaped the sheet, while rotating paste applicators supplied adhesive to its side and bottom laps. Aprons and rollers carried several bags through successive stages. Wolle asserted that every revolution of the main shaft completed one bag and that operation at thirty revolutions per minute could produce 1,800 bags per hour. That figure is the inventor’s stated capacity, not an independently verified factory measurement.
For food sellers, the importance of such machinery lay in repeatable, lightweight containers for dry goods. Nineteenth-century grocers commonly weighed products such as flour, sugar, grain, tea, coffee, salt, feed, and dried fruit from bulk supplies. Archival records show that later bag manufacturers served millers and vendors of flour, buckwheat, salt, and animal feed. It is therefore reasonable to connect mechanized bag production with the expanding trade in measured retail portions, although Wolle’s patent itself names no particular food and does not prove immediate adoption by grocers.
Wolle’s bags were not yet the familiar self-standing grocery sacks of the twentieth century. Their folded construction was closer to an envelope-style bag. Later inventors refined bag-making machinery, most famously Margaret E. Knight, whose 1871 patent formed flat or “satchel” bottoms from a continuous paper tube. Her subsequent improvements helped establish the square-bottomed form that could stand open while being filled and was better suited to bulky groceries.
The 1852 patent nevertheless marks an important step in transferring packaging work from hand labor to coordinated machinery. Standardized bags could be produced rapidly, transported empty with little weight, filled at retail, and discarded after use. Paper remained unsuitable as a complete barrier against moisture, grease, oxygen, or pests, so later food packages added coatings, liners, multiple plies, and sealed inner wrappers. Modern flour and sugar sacks, takeaway bags, and paper grocery carriers belong to this longer history of inexpensive fiber-based packaging, though their materials and construction differ substantially from Wolle’s design.
Historical context
The United States was growing rapidly: the 1850 census counted 23,191,876 residents in 30 states, an increase of 35.9 percent since 1840. Most Americans still lived outside large cities, but railroads, canals, mechanized mills, and expanding urban markets were moving greater quantities of flour, sugar, grain, and other staples through commercial distribution. Grocers generally sold many dry foods from bulk containers rather than in sealed branded packages. Wolle’s machinery appeared during this transition from craft production and local provisioning toward standardized industrial goods and increasingly elaborate retail networks.
Evidence
Written sources
StrongUnited States Patent No. 9,355 directly records the inventor, patent date, residence, claimed mechanisms, drawings, and operating description.
Dating
StrongThe patent specification is explicitly dated October 26, 1852.
Geographic attribution
StrongThe patent identifies Francis Wolle as being of Bethlehem, Northampton County, Pennsylvania. Springfield, Massachusetts, is not the documented location of this 1852 patent.
Preparation method
StrongThe specification directly describes feeding paper from a roll, cutting, folding, pasting, lapping, and mechanically advancing bags through successive production stages.
Food identification
LimitedThe patent does not identify foods placed in the bags. Connections to flour, sugar, salt, feed, and other dry groceries come from broader packaging history and later commercial archives.
Historical interpretation
ModerateThe patent securely documents mechanization, but its immediate economic effect, production volume, adoption rate, and reduction in retail packaging costs are not established by the patent alone.
Visual reconstruction
ProbableA reconstruction can follow the patent drawings, but colors, factory surroundings, operators, finished-bag appearance, and food use would remain interpretive unless supported by additional period evidence.

Limitations
- majorcoordinates
The supplied Springfield, Massachusetts, location conflicts with the 1852 patent, which identifies Francis Wolle as being of Bethlehem, Pennsylvania. Springfield is associated with Margaret Knight's later paper-bag work, not Wolle's 1852 patent.
- moderatetitle
The title implies that the paper bag itself was patented. Patent No. 9,355 specifically covered Wolle's machine and combinations of mechanisms for manufacturing paper bags.
- moderatedescription
The patent does not name flour, sugar, or retail groceries and does not independently demonstrate reduced packaging prices. Those uses and economic effects are reasonable broader historical interpretations, not direct patent evidence.
- moderateevidence classification
The event is directly supported by a surviving written patent and technical drawings. No archaeological evidence is necessary or identified in the supplied card, so describing its basis as archaeological synthesis is potentially misleading.
