SPECIFICATION forming part 0f Letters Patent N0. 528,068, dated October 23, 1894.

Application filed April 28, 183

To @ZZ whom t may concern.-

Be it known that I, GORDON W. BEGOLE, a citizen of the United States, residing at Stony Creek, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Spectacle-Cases, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in spectacle cases and it consists in the construction and arrangement of parts as hereinafter described and definitely pointed out in the claims. t

In the drawings, Figures 1 and 2 show the blank in different stages of formation. Fig. 3 shows the saw cutting the longitudinalkerf or slot in the blank. Fig. 4t shows the shaping saw for shaping the interior of the case. Figs. 5 and 6 are cross sections through the blank after the operations by the machines shown in Figs. 3 and 4 respectively. Fig. 7 is a perspective of the case ready for finishing. Figs. 8 and 9 are cross sections through the finished case. Fig. 10 is aperspective of a finished case. Fig. 11 is an elevation showing a slightly modied form. Fig. 12 is a cross section similar to Figs. 8 and 9 showing a slight modication in interior finish. Fig. 13 is a plan view of a blank showing a slightly `modified form of cutter for shaping the blank.

In the manufacture of tlie case I preferably start the blank, substantially as shown in Figs. 1 or 2, the blank A, shown in Fig. 1 simply having rounded edges, while the blank B, shown in Fig. 2 is shaped to the shape of the desired finished article. The shaping of the blank Or case may be done before the interior of the case is cut out or after. I preferably do it before cutting out the interior as there is less danger of breaking the case, than if it is done after. Taking the blank thus describedI rst cut init a longitudinal groove C which extends from one end to near the other end of the blank. This maybe done by means of a circular saw D as shown in Fig. 3, E being the guide block beside which the work is moved. This groove is of such a depth as to leave at the bottom thereof a thickness of material, as shown at F, substan tially the thickness that I desire to form the Serial No. 472,151. (No model.)

case, and is of a width as great or greater than the mandrel of the saw which I use in cutting out the interior. The blank thus formed, shown in Fig. 5, is next brought to the saw, as shown in Fig. 4, being guided by the guide bar G, the mandrel of the saw passing through the slot or groove C on the blank and the saw cutting the material on both sides of such groove, entering the wood a dis- 6o tance below the top sufficient toleave the casing entirely round and forming the blank as `shown in Fig. 6. This leaves a blank substantially as shown in Fig. 7 with the longitudinal kerf or slot extending from one end to near the other. This kerf I fill up either b v means of a beveled strip H, as shown in Fig. 9, gluing the same in, or by means of a bridge strip I, as shown in Fig. 8, leaving a recess .I for the bows of the spectacles. This 7o bridge strip I preferably make with a reinforcing rib K to strengthen the case.

Instead of making two steps of cutting the kerf and sawing out the interior I may do this in one operation, as shown in Fig. 13, by ar- `ranging cutters L on the mandrel of the saw,

so that a path or groove will be cut in addition to that made by said cutters.

What I claim as my invention is- 1. A case for spectacles consisting of a fiat 8o non-yielding integral block, having a cut out fiat chamber in its center,'open` at one end and closed at the opposite end, a relatively narrow groove in one of its sides, of a length less than the length of the chamber, and a narrow closing strip for the groove formed separate from the block, secured to the case,

substantially as described.

2. As a new article of manufacture, a spectacle case formed of a single piece of wood 9o having a chamber and a longitudinal groove therein, and a closing strip for the groove secured to the case and formed with a dat under and arched upper face, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
