Manufactured by Carroll Muzzle Co. - Caroll IA

A smooth wire muzzle attached to a leather strap is set up to swing up sufficiently to allow grazing and drinking, but drops over the front of the nose and mouth to prevent sucking when the head is raised. Advertising notes the smooth muzzle does not irritate or injure the udder which is the target of the attempted sucking. An 1892 write-up for Shaw's Calf Weaner names the manufacturer.

Manufactured by Whiting Manufacturing Co. - South Framingham MA
Assigned to Frederic Allen Whiting - Framingham MA

This screw-adjust nut wrench has the "fixed" jaw on a pivot with a spring holding the jaw. The jaw will spring partially open on "reverse" movement, allowing for ratchet type movment when using the wrench on square headed nuts. The swinging toggle on the jaw was to hold the wrench in place when driving vertical lag screws, or working on nuts on vertical bolts. Marketed as the Whiting Ratchet Action Wrench. A March 11, 1897 IRON AGE piece announced the formation of Whiting, Macomber & Whiting to manufacture this wrench. A July 1, 1897 IRON AGE notice lists four sizes -- 6 inch through 12 inch. Johnson later refined the idea of the swinging jaw -- see patent no. 622,486.

Manufactured by F. D. Kees - Beatrice NE

Heavy wires forming a halter-like frame, with connecting link, and twisted together at the front to form prongs. Circumstances of design, timing and location lead to the conclusion this was realized as the F.D. KEES (Beatrice, NE) "Surprise" weaner. An 1891 write-up for the weaner notes "developed by a practical farmer" and "a concave is attached to the prongs to stiffen them." It is one of six calf weaners shown in an 1891 HIBBARD, SPENCER, BARTLETT & Co. catalog.
