T. N. STERRY. MAGNETIC ATTACHMENT FOR WINDOWS.

THOMAS N. STERRY, OF NORWICH, CONNECTICUT.

MAGNETIC ATTACHMENT FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 451,603, dated May 5, 1891.

Application filed uly 2,1890. Serial No. 357,568. (No model.)

To all whom, it may concern:

Beitknown that LTHOMASNSTERRY,acitizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented a certain new and useful Improvement in \Vindows, said improvement being fully set forth and described in the following specification, reference being had to the accompanying sheet of drawings,in which- Figure 1 is a view of a window having my improvement added thereto, and Fig. 2 is a perspective view, considerably enlarged, of a portion of the sash, showing also elementary features of which my said improvement consists.

My invention is applicable to all windows held in a surrounding frame and adapted to slide therein, and has for its object to prevent undue rattling of such windows and to make such close joints between sash and frame as to exclude dust and cold.

Said invention is particularly valuable when applied to the windows of cars and other vehicles in which the unavoidable jolting causes such windows to vibrate and rattle.

It is a common practice to fit car-windows snugly in theirframes, so snugly that unusual dampness serves to swell the sash and render it well-nigh impossible to raise such windows.

My invention seeks to overcome the existing difiiculty in a cheap and practical manner.

Referring to the drawings, a indicates the window-sash, and b the surrounding frame, both being precisely as now commonly used. The sash at each side is channeled to receive a bar-magnet 0, whose two poles c 0 project toward the face of the sash and are about flush therewith. Adjacent to said poles, and fixed rigidly in the frame I), are rods d, of iron, that form the keepers of the magnets. The rods cl project upward into the window-frame and are of such length that when the windowsash is raised both poles of the magnets remain in contact with said rods or keepers. It will now be understood that the magnets 0, being fixed in the sash, will act constantly to draw said sash into close engagement with the frame and thus insure at all times a close joint and also overcome any tendency to rattle. A sash so provided with a magnet does not require to fit snugly in its frame and may be raised or lowered readily. WVhile the magnets act with considerable power to draw themselves to the keepers, they do not interfere materially with the raising or lowering of the windows. It will be obvious that electro-magnets could be substituted for the permanent barmagnets illustrated, but are not deemed so practicable, as they would be attended with greater expense in fitting up and in maintaining a constant electric current, and I therefore prefer the simple form here illustrated.

Having described my invention, I claim- A window and sash, one bearing a magnet and the other a keeper, the said elements being combined substantially as and for the purpose specified.

THOMAS N. S'IERRY.
