OPERA-GLASS HOLDER.

SPECIFICATION forming part of Letters Patent No. 477,643, dated June 28, 1892.

Application filed January 11, 1892. Serial No. 417,654 (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH W. BUGHBIND- ER, Jr., a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Opera Glass Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in opera-glass holders; and it consists in the peculiar construction of a folded or hinged holder with a suitable handle designer]. to be permanently attached to the frame of the opera-glass and so constructed that it may be folded into such shapethat it may be readily inserted into an ordinary opera-glass case.

The invention further consists in the peculiar construction, arrangement, and combina tion of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is a longitudinal section of an opera-glass, showing my improved opera-glass holder partly in elevation and partly in section with the handle extended. Fig. 2 is a cross-section through the opera-glass with the handle folded, the whole being placed in the ordinary case. Fig. 3 is a detached perspective view of the hinged joint and the connecting plate or bracket. Fig. 4 is a vertical central section therethrough.

A is an ordinary opera-glass; B, the ad justing-screw thereof, and C the central cross-bar of the frame, to Which,in this instance, I have shown my holder attached. It may, however, be attached to the other cross-bars of the frame or to other parts of the opera-glass Without in any Way changing theinvention; but the glass is better balanced and the device may be more readily attached and folded when applied to the cross-bar O.

D is a bifurcated yoke adapted to embrace the cross-bar O and to be secured thereto by means of screws E, passing through eyes F, formed in said yoke. In place of having this bifurcated yoke, it may be simply a plate or any other construction which may be conveniently secured to the opera-glass and to the frame thereof. Secured to this yoke is a hinged section consisting of the two parts G and H, preferably cylindrical, the part G having a slot I in one side of the lower end and the part H having a rib J, adapted to engage in said slot, a pin K forming the pintle of a hinged joint between the two.

L is a handle made in telescopic sections, the upper end section M of which is adapted to receive the part H of the hinged section, and is formed with an interior rib or stop N, against which a corresponding collar or rib O on the section H is adapted to engage to prevent the disengagement of such part from the handle and not allow of a movement of such part into the handle.

The parts being thus constructed, they are intended to operate as follows: By withdrawing the handle away from the hinged section until the collar 0 strikes the collar N the hinge is free to act and the parts may he turned in the position shown in Fig. 2, the handle being closed and fitted .between the two body portions of the opera-glass and allowing of its insertion into the case.

To use the holder to support the glass, the telescopic sections are extended, and then the operator, taking hold of the upper section M,

slides such section over the hinged joint, preventing its turning. The parts being then in the position shown in Fig. 1, this will rigidly hold the glass upon the handle and allow of its use Without danger of disengagement, suitable friction being provided between the parts in this position to hold them against accidental displacement.

While I have shown this specific construction and consider this the most advantageous form in which to construct my invention, it is evident that many modifications may be applied embodying my invention, which I consider, broadly, to embrace any construction in which a hinged section is attached to the opera-glass, with means for locking the hinge when the handle is extended.

What I claim as my invention is 1.
