Welcome

Thank you for stopping by at Geararium, a museum dedicated to history of gears and toothed wheels. Gear - is a toothed machine part, such as a wheel, cylinder, or section of a shaft that meshes with another toothed part to transmit motion or to change speed or direction. Rium - is a Latin word for a place. Early gears, also called cogs, sprockets, ratchets and interesting objects with exposed toothed wheels have been gathered here. They became parts of a time machine which is able to take back in the age of mechanics. Geararium is an ongoing non-profit museum project originated in Surrey, BC, Canada. At this time museum has an on-line status, but soon it might become a travelling exhibition or a permanent place open to visitors.

Hopefully through this museum these reminders of mechanical past will be re-discovered again and become a source of inspiration for designers, engineers, Steampunk enthusiasts, visual artists, historians and everybody else who might be passioned about art and technology. Please, scroll down to see some objects from the museum's collection. If you have any questions or suggestions, you are welcome to contact Roma, a museum curator:

 

"Occupational CDV photo of engineers and a pattern of a gear"
Origin: United States, 1865-1880
Size: W=54 mm, H= 89 mm
Note: An occupational photograph, CDV or Carte De Visite depicting workers, millwrights or engineers taking measurements of a gear pattern in a studio. Notice a carpet on a floor and missing teeth on the pattern. It is possible that this pattern was intended for casting a wallover, a toothed wheel for a windmill. Early pattern is a wooden prototype of a part, in our example it is a gear, that is going to be cast out of iron. A pattern is skilfully crafted out of multiple pieces of wood by a pattern maker. It is then goes to hands of foundry worker. The pattern is placed inside a box filled with special sand to leave a cavity. Hot metal is poured then into a cavity creating a metal copy, a perfect cast iron gear widely used in early industrial machiniery.

 

"Casting pattern of a gear with curved reinforcements of spokes"
Origin: United Kingdom, 1850-1880
Material: Wood
Size: D=910 mm
Note: This early pattern of a gear features a very unusual curved design of reinforsement plates between
the spokes. Such design could have a decorative purpose to enhance the appearance of an exposed gear or a functional purpose, to reduce the stress on freshly cast metal during cooling period.

 

"Commemorative plaque of Foundry in a name of J.Piat, an engineer"
Origin: France, 1853
Material: Cast iron
Size: D=230 mm
Note: This interesting plaque features a big spur type gear and a small bevel type gear that were cast
separately and then attached to a main composition.

 

"Antique occupational CDV photo of an engineer and a pattern of a gear segment"
Origin: United States, 1865-1875
Size: W=54 mm, H= 89 mm
Note: It is possible that Thomas Hick, a gentleman on this photograph could be a Civil War engineer. He is holding a hammer resting it on a wooden segment of a gear. Such a segment would be cast multiple times and then assembled together to make a bigger size of a gear.

 

"Casting pattern of a gear with curved spokes"
Origin: United States of America, 1890-1900
Material: Wood
Size: D=700 mm
Note: This pattern has an interesting starfish-like design of the spokes. Such curved design not only adds pleasant apperance to the cast gear but also reduces the stress on spokes.

Notice the two openings on each side of a pinion (gear) designed for oiling the model.

 

"Wooden pattern of a gear with a square center and modified hub"
Origin: Saxton, PA, United States, early 1850-1870
Material: Wood
Size: D=620 mm
Note: This early example of a pattern of a gear has been covered with a layer of shellac. Pattern makers of the past were using such material to protect the pattern from wood borers and also prevent it from drying and shrinking. Notice the silhouette of a square hub at the center. It has been replaced with a small round hub possibly due to modifications in machinery.

Material: Cast iron
Size: D=300 mm

 

"Casting pattern of a gear Squiers & Rich"

Unfortunatelly, the two front wheels and guiding level have been lost. Notice an interesting gear train that includes three gears (cog wheels). It is possible that this velocipede, pre-bicycle or four-wheeler has never been put into production. It would be interesting to make a real-size prototype and to try Ackerman's version of a geared velocipede.

Coming soon! A new museum project Flying Boiler is dedicated to early fascination of steam engines. Objects in the collection include Victorian era scratch built models of horizontal and vertical steam engines with decorative features, interesting photographs of model makers and their creations, patent models related to steam, and many other items that represent early Steampunk movement. Here, steam is a form of art.
