Here's another classic stick, the Grover. Similar in many ways to the Rouse Job Stick, the Grover used a clamp that operated in the same way as the Job Stick. However, the knee did not have teeth fitting into holes in the rail - the clamp simply used friction to hold the knee in place.
This particular version of the Grover was made by the Golding Company in Boston. According to Speckter, the stick was invented by Oliver S. Grover in 1855. The knee has a strap of steel attached to it that wraps around the knee and under the body of the stick. The knee does not have a brace of any kind. This stick is 10 inches long with a depth of 13 picas. The shape of the clamp differs somewhat from the original Grover stick, this one more closely resembling the later Rouse clamp. This stick was originally nickel-plated, although much of the plating has worn off. There is a patent date on the body of the stick - it is very hard to read, but looks like 1888, although one or both of the 8s may be a 6. In any case, the Grover was a very popular style of stick, and was made by a number of different manufacturers. I do have some with the original style of clamp, and I will post a photograph of this clamp in some future posting.
