PETER W. JACOBY, OF YORK, PENNSYLVANIA.
LENS AND STRAP GAGE.
Specification of Letters Patent.
Patented Dec. 26, 1916.
Application filed January 22, 1916. Serial No. 73, 745.
To all whom it may concern:
Be it known that I, PETER W. JACOBY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Lens and Strap Gages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to new and useful improvements in lens and strap gages and the principal object of the invention is to provide a device by which lenses may be tested as to their thickness in order that the straps for holding the same may be properly adjusted.
Another object of the invention is to provide a device which is particularly simple in construction and which is adapted to be folded to occupy a minimum amount of space.
Still another object of the invention is to provide a device adapted for testing the proper set of the strap without removing the screw therefrom.
With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a view illustrating the gage in use. Fig. 2 is an end elevation of the gage showing the same in its folded position, and Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 1.
Referring to the drawings, the numeral 1 designates the pivot pins of the various leaves of the gage which are designated generally by the numeral 2. Each of these leaves comprises a body 3 having formed near one end an opening for the reception of the pivot pin, while the opposite end is curved as at 4. A gage slot 5 is formed in each of the leaves and is of a thickness equal to the thickness of the leaf so that the thick ness of the lens when slipped in the slot may be readily determined. A suitable guide slot 6 is formed in each of the gage leaves and these slots 6 are adapted for the accommodation of the screw in the strap which holds the lens. The slots 5 and 6 extend inwardly from one edge of each leaf as clearly shown in Fig. 1 so as to readily accommodate the lens and screw.
v strap by the lens and the As illustrated in Fig. 2 the gage leaves vary in thickness as do the openings or slots 5 and it will thus be seen that when a lens is slipped into one of the slots its thickness will be indicated by the thickness of the leaf. In order that the strap may be adjusted to the proper thickness for the reception of the lens the same is slipped over the end of the leaf as shown in Fig. 1 so that the screw thereof passes into the slot 6 and it will thus be seen that the length of thestrap may be pressed inwardly or sprung outwardly ac cording to the thickness of the leaf. In this way it will be seen that the strap may be properly prepared for the reception of the lens and thus the necessity of setting the risk of breaking the lens due to such an operation is eliminated.
WVhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.
What is claimed is 1. A lens and strap gage comprising a plurality of leaves of various thicknesses each leaf being provided with slots in one edge of a width equal to its thickness.
2. A lens and strap gage comprising a plurality of leaves of various thicknesses, each leaf being provided in one edge with a slot of a width equal to the thickness of the leaf and means pivotally securing the leaves at one end.
3. A lens and strap gage comprising a plurality of leaves of various thicknesses, each leaf having a gage slot in one edge, of a width equal to the thickness of the leaf, said leaf also having a guide slot intermediate the gage slot and the end, a curved end on each leaf and means pivotally holding the leaves together near the end opposite the curved end.
In testimony whereof I affix my signature in presence of two witnesses.
PETER W. JACOBY.

PETER M. BECKER, CLARENoE E. KOHLER.
