No. 12655.—29th May, 1900.—GEORGE CROCKER SMITH, of 57, Odessa Street, St. Kilda, Victoria, Mechanist. New or improved grip or fastening-apparatus for the windows and louvres of railway-carriages, tram-cars, and other vehicles, and also applicable to drawers, gates, and the like.

Claims.—(1.) In combination, a segmental gripper as L, a shaft on which said gripper is mounted as K, a screw-threaded shaft as D and corresponding bearing for the screw to work in, means for operating the shafts so as to partly revolve and allow them the forward-and-backward movement, and a pressure spring, the whole being mounted upon suitable lugged plate as A, substantially as and for the purposes set forth. (2.) In combination, a slotted metal plate as A, upon which are mounted bearings as B and C, a multiple-screw shaft as D, a handle as E, a slot in the plate A as H, means for securing the handle to the shaft D, substantially as and for the purposes set forth. (3.) In combination, a shaft as K, bearing as M, expansion spring as N, and a segmental gripper as L, a chamber as S in which L is arranged to work mounted upon said shaft K, means for securing K to operating-mechanism, substantially as and for the purposes set forth. (4.) In combination, two shafts as D, D1, placed in line, bearings as B, B, and C, C, springs as J, J, operating-handle as E, a shank E1 arranged to operate said shafts, substantially as and for the purposes set forth. (5.) In combination, a window-sash having a chamber as S cut therein to permit a segmental grip as L to work in spring as N, bearing as M, and shaft as K, substantially as and for the purposes set forth. (6.) In combination, a shaft as D having at one end thereof a male-screw thread engaging with female-screw-thread bearing as B, and being cylindrical and smooth and revolving in a plain parallel bearing as C at the other end, means for operating such shaft so as to cause it to partly revolve, and spring as J, the whole forming an actuating-mechanism for securing or releasing the gripping- or locking-appliance substantially as and for the purposes set forth. (7.) In combination, a shaft as D, one end of which carries means for forming an articulation with another shaft as K, a multiple-screw thread mounted upon one portion of said shaft as D, and corresponding multiple-female-screw bearing as B, a slotted metal plate as A carrying the screw bearing B and smooth parallel bearing as C, means for moving D backward and forward in its respective bearings, a gripper or locking-shaft as K provided with a gripping-device at its end, substantially as and for the purposes set forth. (8.) In combination, a slotted plate as A, operating-shank as E1, shaft as D, and locking-bar as R, and means for operating the said bar R so as to block the movement of the shank E1, substantially as and for the purposes set forth. (9.) In combination, an exterior handle E4, shank E5 operating through a slot as X, interior handle E3, shank E1, and shaft as D, and its bearings, the whole arranged to actuate a shaft as K upon or to which a gripping-device is attached, substantially as

and for the purposes set forth. (10.) In combination, a frame as T, having at one side a pressure plate O, and upon the other side a gripper operated by shafts as K and D, means for rotating or partially rotating said shafts so as to cause a counter-pressure between said plate O and the gripper, and thus cause the frame to be firmly held in position, substantially as and for the purposes set forth. (11.) The general combination and arrangement of the several parts set forth in Figs. 1 to 6, inclusive, on the drawings, forming a complete gripping- or fastening-apparatus, substantially as and for the purposes set forth.

No. 12656.—29th May, 1900.—GEORGE WESTINGHOUSE, of Westinghouse Building, Pittsburg, Pennsylvania, United States of America, Engineer. Improvements in draught appliances and couplings for railroad-cars.

Claims.—(1.) The combination, with a car-frame, of a pressed-metal channel-casing, secured to the central frame-members, and having abutments within it upon which draught and buffing strains are received, and through which they are transmitted to the car-frame, substantially as and for the purposes described. (2.) The arrangement on a car-frame of coupler-heads adapted to be coupled either to automatic or link couplings, and buffer-blocks adapted at will to be readily connected to or disconnected from the buffer-beams, substantially as and for the purposes described. (3.) In a car-coupling, the combination of a coupler-head, a knuckle pivoted thereto, a shank fixed thereto and having a vertical socket adjacent to its inner end, a draught strap or yoke having its outer end bar fitted freely in said socket, and a removable section connected to the draw-bar shank and maintaining the draught-strap in connection therewith, substantially as described. (4.) In a car-coupling, the combination of a coupler-head, a knuckle pivoted thereto, a draught strap or yoke pivotally connected to the coupler-head, springs bearing on the shank of the coupler-head and normally maintaining it in the longitudinal central plane of the car, and stops rigidly connected to the draught-strap and limiting the lateral movement of the draw-bar, substantially as described. (5.) In a car-coupling, the combination of a coupler-head, a knuckle pivoted therein, a spring-pressed pressure-block fitting in a lateral guide-socket in one side of the coupler-head, and a vertical abutment on the opposite side of the coupler-head, and a coupling-hook pivoted horizontally thereto, substantially as and for the purposes described.
