Today in 1860, US Patent 29666 A was issued, an invention of Robert D. Bryce, for his “Attachment of Covers to Glass Vessels,” or “Pitcher Cover.” There’s no Abstract, although in the description it includes these claims:
I have invented a new and useful Improvement in the Mode of Attaching Metallic Covers to Mugs, &o.; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being’ had to the accompanying drawings, forming part of this specication, in which Figure l is a perspective representation of a glass mug, with a metallic cover attached thereto on my improved plan. Fig. 2 is a side view of the metallic cover, detached from the mug showing a vertical section of the hinge piece, and the handle of the mug in the same plane. Fig. 3 is a View of the cover and part of t-he handle of a mug similar to Fig. 2, showing a slight modification of the mode of attachment.
In the several figures, like letters of reference denote similar parts.
There are several articles of domestic use, which it is convenient to furnish with metallic covers, to open readily with a hinge, such as lager-beer mugs, cream-pitchers, molasses-pitchers, and other vessels. These metallic covers are made with a. hinge usually placed near the handle, the hinge piece being in two pieces, united by a pin or pivot, the upper hinge piece being united to, and forming part of the cover, and the lower hinge piece being attached to the vessel and thereby securing the cover to the vessel. It has been found difficult, however, to limit the lower hinge piece of the cover to the vessel, so as to form a neat and workmanlike job, without casting it on to the handle of the mug, pitcher, but this is expensive in itself, and is very apt to break the vessel, if it be made of glassware.
My improvement consists in attaching the upper hinge piece of the cover immediately to the handle, or to a projection on or near the rim of the vessel, so as to dispense with the lower hinge piece of metal.
