WINDOW, PANEL, OR OTHER SLIDING` FRAME.
SEECIFICATION forming' part of Letters PatentNo. 692,039, dated January 28, 1902. Application filed July l, 1901. Serial No. 68,245. (No model.)A
dated January 30, 1901,) of which the following is a specification. This invention relates to windows, panels, and other sliding frames, its object being to provide means for holding the window or panel in any position without the use ofstraps, stops, cord, pulleys, or weights, such as are generally used for this purpose.
Although the invention is specially designed for use in a carriage-window and is hereinafter described as so applied, it is to be understood that it is equally applicable to all windows, panels, or frames which are opened and shut by a sliding motion. u
In the accompanying drawings, Figure lis an elevation of acarriagewindow fitted to a door and constructed according to this invention, some ofthe door-panels being removed for the sake of clearness. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a section on the line 3 3 of Fig. l. ,y
Like letters indicate like parts throughout the drawings.
The door A is fitted with a window B in its` frame B', adapted to slide in grooves A',
Vformed in the side frames A2 of theqdo'or A.
Aspring-controlled lever or arm C is" pivcted at C on each side of the sash, both levers having an operative connection with the window-frame B'. In the preferred construction thelevers C are slotted at C2, and a pin B2, carried on a downward extension B3 of the frame B', engages the slots in both levers. The pivot-spindles C' of the levers C are carried in boxes D, secured to the side frames A2 of the door. The boxes D each contain a coiled spring D', one end of which is secured to the box or other fixed part,` the other end being fastened to the pivot-spindle C' or to the lever C. The springs D' may be arranged to act upon the levers in various ways-for instance, one spring may tend to move its lever upward, while the other is oppositely ar ranged. In this case the strength of the spring tending to move its lever upward would be at least sufficient to counterbalance the sum of the forces exerted by the weight of i the window and by the other spring. Again, both springs may be arranged so as to tend to move their levers upward, the combined strength of the springs being sufficient to hold `the window in any position.
A handle or the like E is secured toa suitable part of the window-frame B' on the inside, whereby the window may be raised or l shown, or may be tapered to allow the win-` dow to be locked in the ordinary manner, a draft and dust excluder beingpreferably provided of any desired construction. In the former case any convenient catch may be provided for locking the window in its closed position. Such a catch would conveniently be capable of being operated from both ,the inside and outside.
`iVhat I claim as my invention, and desire to secure by Letters Patent, is4
l. The combination of asupport, a sliding frame therein, two levers pivoted at one end to the support at opposite sides, an operative connection between the frame and the other end of the levers and springs acting on the levers for the purpose set forth.
2. The combinationof a support, a sliding frame, therein, twoslotted levers pivoted to the support, a pin on the frame engaging the `slots in the levers and springs acting on the levers for the purpose set forth.
3. The combination of a support, a sliding window therein, two spindles on the support,
'a slotted lever on each spindle, a pin on the window engaging the slots in the levers and a coiled spring acting on each of the spindles to operate the levers substantially as set forth. In testimony `whereof I have signed my name to this specification 4in the presence of two subscribing witnesses. v
