Improved Saw Gummer
This engraving represents a new method of gumming circular saws, or, in other words, cutting out the throat of the tooth so that the dust will have a free opportunity to escape without clogging and binding the saw.
The tool is designed to be applied to the mandrel the saw itself works on, so that by merely removing it, and substituting the gummer, the operation can be performed without any other special fixtures.
The glimmer itself consists of a grindstone or emery wheel, A, made of vulcanized rubber and emery, in the shape of a ring. This ring is clamped between two iron plates, B, and firmly held by screws, so that it cannot shift or change its position. Thus constructed, it is applied to the saw mandrel and secured thereon, as the saw itself is, with a nut.
The saw, when operated on, is laid on the carriage or timbers of the mill—as shown in the engraving—which renders it easy of access during the job.
Many persons using this gummer speak highly of its qualities, and the proprietors are prepared to fill orders for them. It was patented on Nov. 15, 1864, by L. A. Dole. For further information address Dole, Silver & Deming, manufacturers, Salem, Ohio.
