MULTIPLE MIRROR..

Speccaton of Letters Patent.

Patented Dec. 18, 1906.

Application led December 6, 1905. Serial No. 290,528.

To all whom it may concern,.-

Be it known that I, JOHN II. PnTRosKEY, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Multiple Mirrors, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to improvements in multiple mirrors; and its object is to provide certain improvements in the construction of the supporting-frame whereby a very strong, light, and durable construction is secured, and which is so made that it may be taken apart for close packing and may be quickly and easily assembled.

It is also an object of the invention to so construct the vertical side posts of the supporting-frame that the connecting-tube to which the laterally-extending supportingarms ior each side mirror are secured to hold said arms in alinement may be placed within said posts to turn therein, thus giving a rigid supporting frame having stationary side posts and permitting the use of thin tubing for said posts, which may also be of comparatively small diameter.

A further obj ect of the invention is to provide a device having the several advantages of the particular construction, arrangement, and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in which- Figure l is a perspective view ot a device embodying the invention. Fig. 2 is an enlarged detail of one of the side posts of the supporting-trame, showing the same in vertical section with the legs and supportingarms attached 5 and Fig. 3 is a transverse section or' the same on the line of Fig. 2.

As shown in the drawings, 1 is a rectangular supporting-frame consisting of tubular vertical side posts 2, connected at their upper ends by an ornamental cast connecting bar or bracket 3, provided at each end with a socket 4 to receive the ends of said posts, which are secured therein by set-screws 5 and connected at their lower ends by an ornamental cast connecting bottom bracket 6. Intermediate their ends these connecting members or brackets are each provided with a socket to receive the pivot-pins 7 -on the upper and lower ends of the frame of a center mirror 8, which is of a width to just permit of its swinging horizontally on said pivots within the supporting-frame.

A casting 9, provided with an open socket or sleeve bearing 10 to receive the extreme lower end of the tubular post 2, is secured to each post by a screw 11 to prevent the turning thereon, and this casting is formed with an olset 12 and a pintle or stem 13, extending downwardly from the lower end of said oii'set in axial line with its bearing. The ends of the bottom connecting member or bracket 6 of the frame and ornamentallydesigned supporting-legs 14 are secured to these downwardly-extending stems by forming each leg and bracket end with a sleevesegment 15, which segments together form tubular clamping-sleeves to embrace these stems and are secured together and clamped rigidly to the same by screws or bolts extending through openings in ears 16 on said seg-4 ments. Each leg is thus formed with onethird of a clamping-sleeve, the part on one end of the bracket forming the other third, and thus, where the three parts or segments are drawn together by the clamping-screws, said connecting-bracket and two legs are firmly secured to each post 2 in such a manner that they may be quickly detached or assembled. To further secure these parts to the pintles, screws 17 may be tapped through the sleeves into the pintles,

Within each post 2 is a rod or tube 18, which is longer than the post, projecting therefrom a s ort distance at its upper end and at its lower end extending across the oliset of the casting 9 into engagement with a shoulder or seat 19 therefor formed on the casting at the lower end of the open side of the offset. Secured to this lower end of each tube is a laterally-extending supporting-arm 20, having a bearing or sleeve 21, which is of a length to just fit in between the lower end of the sleeve-bearing 10 and the shoulder 19 and is detachably secured to the tube by a set-screw 22. 'A similar arm 23 is secured to the upper projecting end of each inner tube in a like manner, and a iinishing cap or IOO knob 24jis secured to the upper end of each ,of said tubes by being provided with a stud to project into the same. Between the outer free ends of these arms are pivoted the side or wing mirror frames 25, which may be turned to any desired position on these pivots, as the arms are of sufficient length to allow the frames to swing past the posts 2, and the position of the mirrors may be changed by swinging the arms forward or back. v"The arms are held in alinement when swung, thus holding themirror-frames in their perpendicular position by being firmly secured to lthe inner tubes, which turn with said arms.

The connecting brackets and posts with their end castings and the supporting-legs form a very rigid supporting-frame, all members of which are firmly and rigidly held against turning, and by providing each post with'the offset so'that the arms may be secured to a tube or rod rotatable within said posts light tubing of small diameter may be used, as the outer tubing forming the posts will be of a diameter to give suiiicient rigidity and strength to the frame when made of thin tubing and the inner tubes or rods turning within. the posts are strengthened thereby so that they may be of small diameter. The parts are so secured together that they may be quickly 'and easily put together an inexperienced person, thus permitting ofthe device being shipped in the knockdown, and the manner of forming the legs and bottom bracket permits the separation of the legs, so that the device may be packed in a small space, and but few screws or bolts are necessary to secure all firmly in place.

y Having thus fully described my invention, what I claim isl. Ina multiple mirror, the combination of a supporting-frame consisting of tubular side posts open at each end, a top bracket connecting the upper ends of said posts and secured thereto, members secured to the lower ends of said posts and extending downwardly and laterally therefrom, a bottom bracket connecting said members, legs attached to said members, a tube rotatable within each post and projecting `from the ends thereof, laterally-projecting arms secured to the projecting ends of said tubes, and mirror-framespivoted between the free ends of said arms.

2.'.In a multiple mirror, the combination of a supporting-frame consisting of tubular side posts open at each end, atop bracket connecting the upper ends of said posts and secured thereto, a casting secured to the lower end of each post and formed with an offset, a

lbottom connecting-bracket and legs secured the projecting ends of the tubes, and mirrorframes pivotally attached to the outer ends of said arms.

3. In a multiple mirror, the combination of a supporting-frame consisting of tubular side posts open at each end, a connectingbracket secured to the upper ends of said posts, castings each formed with an open bearing to receive the lower ends of the posts which are secured therein and with an offset portion having a stem on its lower end extending downward in axial alinement with the post, a bottom bracket secured at its ends to the stems, legs secured to the stems, tubes rotatable in the posts and projecting from the ends thereof, arms secured to the projecting ends of the tubes, and mirrorframes pivoted between the free ends of said arms.
