Be it known that I, HENRY CHAMBRLAIN, of the town of Dayton, Waupacca county, State of'Wisconsin, havejnven'ted a new and useful Improvement, on Store-Windows, to wit, a revolving store-window; and I do Vhereby declare thatthe following is a full, clear-,and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specication,in vhich Figure 1 is a perspective view. Figure 2, inside view of window withshutters. Figure 3, side view. Figure 4,- springjrods, crossbars,vand springs, fastened to the side of the window-'frame Figure v5, upper section or head ofthe window. Figure 6, section ofthe window-sill. Figure 7, full view ofthe pivot and plates. Figure 9, transverse section of cross-bar and spring. Figure 10, shape of'spring.

To enable others skilled inthe art to make and use my invention, I will proceed to describe its construc- I tien and operation.

The store-window or bulk is constructed in common form, and revolves b'y means of a metal pivot, fie, 7, on drawings, fastened to the centre'of the sill of the window. This pivot consists of a round' metallicplate, with a one and one-half incl?. tube in its-centre, suiciently large to admit the'gas-pipe. This tube or pivotis about four inches in length, goes down through the llole'inthe under plate, Figu'reS of drawings. The lower plate is provided with a strong shoulder, tohe lit-ted into the sill of the windowframe A similar pivot is'alse arranged at 'the upper part'of the window, marked E, iig. 6 of drawings.' I y The window is kept to itsrplace by reason of a spring-bar or lever, marked A, fig. 2 of drawings, which bnr or lever is arranged with a joint `in the middle, marked a. l This is placed *across the sill of the window-frame.

The ends'of this lever pass through staples, fastencdat the side of the window-sill, markedb and c. The lever is fastened to the window-sill by means of screws, marked de on drawings. 0n the underside of one of those sections, iig. 9 of drawings, is placed a spring, marked A, so as to spring it back, and keep the -window in its 1 place. When the lever is pressed dow-n, it permits the window to revolve.

For the purpose of' makin-g the'sides ofthe window air-tight when shut, there are arranged on the side of the frame ifv. 4 offdratv'inffs two string-rods marked a Z1 and c r2. At each end of those rer endicular bers are 1 a n? l n i placed cross-bers, a c and d. At the' corners a, 5, c, and el are plnccd springs, in the inside, pressing thc'rods and cross-bars against the side of the window. Those bars are kept in their places by being let| into the sillvnnd top or head ofthe window-frame.V On the other side of the window is butone spring-rod, fastened in the same manner as theothers, with n, steel or brass-spring fasten-ed under each end: e

The shutters are fustonedin the'following manner: At the, head of the window, {igi ofdrawings, are placed two spring-bars, marked A and B, each provided with a metal spring at the under.ed ge,'marked e :ind b The ends of those bars are fastened to a bar lying across the. upper part or edge of the shutters C D, which, when the window is turned round, so as to bring the shutters on the outside, is fastcneddown'over the upper end s of same, and when the window is turned back', the shutters are brought on the inside, uy mcans'of the head of the windmr-frame being-made'rounded on the under side, about three inches from vthe rnn'ereilge, or suiicient to admit the spring-bar to rise, lifting the cross-bur lyingl across the shutters up, so ns .to clear the ends of the shutters. t

At the sill ofthe window, iig. 5 of drawings, is also placed :L similar spring-bnr, marked and B, fastened tothe bar C-D, which bar, when the shutters are put in, is prcsscd down, solas to ndmit"'them,rwhich is also eupplie'd'with metallic springs, causing `the bar to spring up-over the under edge of the shutters.

The object andutility of the revolving'store-window^are that. the shutters might befas'tened inthe inside of the store', end then revolved to the outside. Another advent-age is, that the glnssl maybe cleaned in the 'inside of' the store, and for the purpose of ventilation; also to cleanit in the inside in cold'nnd stormy weather.

I elaimvthecombination of thezspring-bar A, the perpendicular bars a,A 1J, 0 and d, the plate C andfD of a store-window, whenconstructed and operated 'substantially as described, and for the purposcscti'orrh.
