To @ZZ whom may concern.'

Be it known that I, ROBERT ADAMS, a subject of the Queen of Great Britain, residing at N o. 7 Great Dover Street, Southwark, in the county of Surrey, England, engineer, have invented certain new and useful improvements in means andapparatus for opening, adjusting, closing, and securing objects hung on hinges or centers, such as easements, fan- IO lights, louvers, ventilators, lanterns, and skylights an'd doors, of which the following is a specilication.

My invention relates to improvements in means for operating revolving window-sashes and other analogous devices; and it consists,

essentially/,in a bell-crank lever pivoted tothe window-easing and connected at one end bya link or arm to the sash to be revolved. The other arm of the bell-crank lever is connected 2O by means of a rod or arm to a vertically-moving the manner of operating the same.

able bar operated by a bell-crank lever, so that v designates the window frame or easing, and 2 the window-sash, which is centrally pivoted in said casing. n

3 designates a bell-crank lever, pivoted to the window-casing at 4. One arm of this 4o lever carries a pivoted link or arm, 5, which is secured to the window-sash. To the other or short arm of the lever 3 is secured an arm or bar, 6, which is also secured to a collar, 7, on the vertically-movable rod 8. This rod 8 moves in bearings or guides 9 9, secured to the wall of the building or other convenient.

support, and is provided with a eollar,10,

which limits its downward movement by abutting against the upper bearing, 9.

To the upper end of the rod 8 is connected, by an arm, 13, one arm of a bell-crank lever, 11, pivoted at 12, the other arnr of the lever being connected with the corresponding arm of a similar lever pivoted to aetuate the next adjoining sash frame. This connection is made by the rod 14, and the latter may be extended and connected to any required number of bell-cranks 11, whereby a series of sashframes may be opened or closed simultaneously, as in a railway-car having ventilators composed ot' hinged sashes. The other arm of the bell-crank 11 is connected by means of a link, 13, to a vertically-movable rod, 8, sliding in eyes 9% The lower end of said rod is threaded, and engages with a sleeve, 16, having a female thread and provided with a mitergear, 17, which meshes with a second drivingmiter, 18, having a squared bearing, 19, which receives a crank, 19. Both the

gears

17 and 18 have bearing within the casing 15, as shown in Fig. 3, and as the crank 19 is operated the sleeve 16 will revolve and draw the rod 8 down, or raise it.

In order to secure perfect fit and retain all the parts securely in place, I prefer to employ a tube, 20", the lower end of which is threaded and screwedinto an aperture in the easing 15.

The operation is as follows: VVhen the sash is in the position shown in Fig. 1, and it is 'desired to revolve the same, and thereby close the window, the rod Sis operated by revolving the crank 19a in the proper direction, thereby raising said rod 8 and the short arm or lever 3,which is connected to said rod. This movement also actuates the bell-crank 11 by means of the link 13, and communicates the action to the next window through rod 14, causing lever 3 to assume the position shown in Fig. 2, thereby revolving the sash and closing the Window.
