ADJUSTABLE MIRROR.

Specification ofLetters Patent. Patgnted D 4 1917 Application filed July 3, 1917. Serial No. 178,409.

of which the following is aspecification.

This invention relates to adjustable mirrors-and more particularly to a means for retaining the same in one of'a number of positions, whereby the user may adjust the 7 after having same to the best advantage for the purpose in View.

Another object of the invention is the provision of a simple and eflicient means of inducing the necessary friction to hold the mirror in its adjusted positions without resorting to the use of screws or other fastening devices of this character, said means being automatic thus relievingthe user of the necessity of operating any locking device positioned the mirror at the angle desired.

Another object of the invention is the provision of a device of the class described which issimple in construction, thoroughly reliable and efficient in operation and inexpensive to manufacture.

Other Objects and advantages will be readily apparent as the nature, purpose and operation of the device are better understood from the following description and claims taken in connection with the accompanying drawings, of which:

Figure 1, is a side elevation. Fig. 2, 1s a. similar vlew w1th parts in 7 section.

Fig. 3, is a detail fragmentary section on the line 3--3, of Fig. 1, and

Fig. 4, is a detail perspective view plate.

Referring to the drawings by numerals, 10, designates a suitable base from which rises a standard 11, having an offset portion 12. The mirror 13, is of any suitable construcof the tion and has secured to the rear face thereof an arm 14, which projects outwardly and is provided with an opening 15, in its free ex tremity. A disk 16, having a downwardly extending stem 17, is secured to the ofl'set portion 12, of the standard 11, by any-suitable means. The disk 16, is vertically slotted as at 18, and is provided with a concentrio opening which receives a pivot 19, said p vot also bemg received by the aperture 15,

in the extremity of the arm 14, whereby the arm is mounted for pivotal movement. A cylindrical plate 20, is slidably mounted on the arm 14, and receives the latter in the centrally arranged opening 21, said arm being preferably rectangular and the opening of like configuration. The plate is provided at its free extremities with the notches 22, the latter serving to embrace the stem 17, and act as stops for the plate when swung into engagement with the stem. A coiled expansible spring 23, surrounds the arm 14, and is disposed between the mirror and the plate 20, in order to normally force the inner periphery of the latter into frictional contact with the outer periphery of the disk, whereby the arm 14, is held against casual rotation on its pivot.

iVliile I have shown and described a means for retaining the arm as applied to a mirror, I wish it understood that the same may be adapted for other uses such as desk lamps and other articles of this character. I also wish it understood that changes and alterationsthat fall within the scope of the appenged claims may be resorted to when desire Having thus described my invention what I claim is:

1. In a friction device of the character described comprising, a standard, a vertically slotted disk, an arm concentrically pivoted in said slotted portion of the disk, a semi-cylindrical plate slidably mounted on said arm, an object secured to the free extremity of the arm and means for normally forcing the plate against the disk to retain the arm in its adjusted positions.

2. An adjustable mirror comprising, a vertical standard. a vertically slotted disk, a stem extended downwardly from the disk and secured to the standard, an arm concentrically pivoted in the slotted portion of the disk, a semi-cylindrical plate slidably mounted on said arm, notches in the opposite extremities of the plate adapted for engagement with the stem, a mirror carried by the free end of the arm and an expansible spring 3. In combination with a standard and a pivoted mirror, of a means for retaining the of the arm, a semi-cylindrical plate slidably latter in its adjusted positions, said means mounted on the arm and means for forcing including a Vertically slotted disk secured the inner periphery of the plate against the 10 to said standard, an arm secured to the mirouter-"periphery of the disk.
