UNITED STATES PATENT OFFICE.
GEORGE P. BERTRAND, OE EAsToN, PENNSYLVANIA.
IMPROVED MlRROR FOR ATTACHMENT TO WINDOWS.
Specification forming part of Letters Patent No. 35,917, dated July 2:2, 1862.
.To all whom it may concern:
Be it known that l, GEORGE P. BERTRAND, of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and Improved Street Mirror; and I do hereby declare that the following is a full, clear, and
exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in Which- Figure l 'represents an inside view of a window provided with one of my improved mirrors. Fig. 2 is a horizontal section of the same. Fig. 3 is a detached transverse vertical section of a portion of the universal joint which serves to adjust the mirror in the desired position, the plane of section being indicated by the line x w, Fig. 2, and looking in the direction of the arrows marked opposite to that line.
Similailetters of reference in the three figu res indicate corresponding parts.
To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings.
rlhe mirror A is suspended by means of a loop, a, from a rod, B, which is provided with an arm, b, fitting said loop, so that the mirror can easily be taken Oft' or replaced Whenever desired. The inner end of the rod B is formed into a plug, o, which ts nicely into a socket in the head d of a vertical plug, d, which rotates freely in a corresponding socket, e, that is attached to the outer end of a bracket, C, which is firmly secured to the side of the window-frame D, outside the window, as clearly shown in Figs. 1 and 2 ofthe drawings.
The plug c is secured in its socketin a horizontal direction, and it is prevented from Working out spontaneously by a nut, f, which also serves to fasten the plug c, and with it the rod B and mirror, from' turning. A collar, g, which is secured to the rod B, prevents the plug c being drawn into its socket beyond the desired joint, and this collar is provided with a segmental recess, h, (see Fig. 3,) which catches over a stop, t', projecting from the side of the head d in such a manner that by this recess and stop the rotary motion of the rod B is confined between certain limits. \Vith out this precaution, on releasing the nut j' at the end of the plug c, the rod B, impelled by the weight of the mirror, would be liable to turn round to such a position that the mirror would be liable to slide ott` from the arm b and to drop down and get smashed.
The plug d is secured in the socket e in a vertical direction or at right angles to the plug c, and it is fastened in the desired posi tion by a nut, j. at its lower end. By the arrangement of the plug d the rod B, with the mirror, can be rotated in a horizontal plane, and the plug c allows of turning the same in a vertical plane within the limits prescribed by the recess h and stop i. By the combined action of the plugs c d, therefore, the mirror can be adjusted with very little trouble in any desired position, and it is obvious that by increasing the lengths of the rod B the sweep of the mirror can be increased at pleasure.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
A revolving mirror, A, hung upon a rod, B, with plugs c d, nutsfj, and stops t', as and for the purpose shown and described.
