Be it.l nown that I, JAMES H. OSGOOD, Jr., of' Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Window-Frames and Sashes, of which the following is a full, clear, and exact description, reference being-had to the accompanying drawing, making a part of this specification, and which represents a perspective View of a window-fra me and sash embodying my improvements, a portion being broken away to show certain details of construction.

My invention consists in attaching friction-rollers of suitable material to the sashes in such it manner as to cause the sash to bear firmly against the frame-t0 hold it when open, and prevent it from rattling or admitting dust and air when closed. 7

Referring to the drawing, areprescnt-s the window-frame, of any suitable construction, and'b c the upper and lower 'snshesrespcctively. I To the upper ends of each sash, at the sides, are attached, by means of books and eyes or staples it h, the cords gg, which pass over pulleys arranged in the frame or above. the sash, so that the sashes are made to counterbalance each other. By attaching the cords to the hooks, as shown, and securing them to the sashes, the 'lzitter may readily be disengaged from the cords when necessary to remove them for repairs or cleaning. Whenever it is desirable to open the lower sash only, the upper one may be fastened in position, and the lower one may be supported at any height by any suitable device in use. A portion of the sash on each side may be cut away or grooved, as shown at Z, in the upper end of the upper saslnand lower end of the lower one, and on thoinner side of the frame are attached friction-rollers, of India rubber or other suitable material, mounted on fixed bearings, and which fit within the grooves or portions of the sash which are cut away. W'hcri grooves are used, they are-formed in an unbroken vertical line parallel with the sides of the frame to a certain distance, where they then.' gradually turn outwardly with a. gentle curve. The rollers are of .such a diameter as to be smaller than the depth of the main part of the grooves, and scarcely come in contact therewith until they reach the curved part thereof. The grooves extend only so far on the sash that when the latter is closed, the rollers will rise out of the groove and. press against the sash in such a manner as to force it more closely againstthe parting hand e, and thus insure a tight fit to the sash within the frame, and when the sash is opened above or heloW,.the roller' willenter the groovee-nd allow the sash to move freely up and down without binding. The said friction-rollers may be attached tothc sash,'and run in grooves formed in the frame instead of as above described. F represents a portion of thest'rip that confines thes'ash in the frame asthinged, so-as to allow it to be opened to enable the sashto beremoved for cleaning or repuirs. The whole portion may be so arranged as to open from top to bottom, if desirnble, thus enabling any person in the house to remove the sash Without the'necessity of 'sending' for a workman to unscrew the side-piece, as it is ordinarilyf'astencd. The said 1 piece may be hinged or pivoted inIany suitable manner, and confined in position by a button or catch of any convenient form.

In the method of hanging sashes as commonly adopted, the cord that sustains the weight ispermanently secured to thesash, and ntense the cord becomes detached-from the sash, or broken, it becomes necessary to remove a portion of the'frauie to repuir the damage, a process thatrcq'uires labor and skill. By attaching the cord, by means of a hook and'eye, to the sash, the latter nuy at time be ensily detached. This method of attachment may he also veryreadly applied to sashes which are already hung in the usual manner. and count-en, balanced by weights. I 7

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the'sash or frame respectively, of grooves-d constructed as described, and the rollers 12, mounted on fixed-bearings, and. operating together as and for the'purpose herein described. 7

In testimony whereofll have signed my name to this'specification in the presence of two subscribing witnesses.
