T. E. DAVIS AUTOMATIC WINDOWPCLOSER Filed Sept. 6, 1921 Patented May 25, 1926.
THOMAS E. DAVIS, OF GHAMBERBURG, PENNSYLVANIA. I
AUTOMATIC WINDOW CLOSER.
Application filed September 6, 1921. Serial No. 498,785.
vent the window from closing with too much force.
Still further objects of the invention and the features of novelty will be apparent from the following specification when taken in connection with the accompanyin drawings, which show one embodiment of the invention, and in whichz Figure 1 is a view in elevation of a window as seen from the inside of the room,
part of the side frames being broken away.
Figure 2 is a view in elevation similar to Fig. 1 showing the sash held in raised position.
Figure 3 is a vertical section of'the struc-.
ture' shown in Figure 2, and
Figure 4 is an enlarged view in detail shown a clamp used on the sash cord, as shown 1n the other figures.
As shown in the drawings, the window frame 11 is of the usual type and comprises boxes 12, in the side members of the frame, which/receive counterbalance weights 13, connected to the lowersash 14 by flexible cords or chains 15, which are guided over pulleys 16. The pulleys 16 are supported in the frame adjacent the top thereof, and openings 17 are formed in the side members of the frame, to permit the flexible members to enter the boxes 12.
The hook 18 is provided on the window sill, preferably adjacent the center thereof, and a similar hook 19 is provided on the lower member of the sash 14, preferably adjacent one side edge thereof. Another hook 20 is provided on the side frame member,
preferably above the top of the sash when the latter is in closed position. In order to hold the sash in raised position, a flexible member 21 is provided, which carries at its one end a ring 22 which may be readily engaged With'the hook 19, and which, at its other end, is provided with a hook 23. A
A clamp is provided for each flexible member 15, and may, as shown in Fig. 4, comprise plates26 adapted to be positioned on opposite sides of the member 15 and be clamped together by bolts 27 having nuts 28 threaded thereon.
In operation the clamps are positioned on the members 15 while the window is in.
closed position, as indicated in Fig. 1. When the window is partly raised, the clamps will engage the .window frame adjacent the opening 17. Further upward movement of the sash 14 will permit portions of the flexible members 15 to be slack as shown in Figures 2 and 3, and the weights 13 will be supported independently of the sash. The flexible member 21 is then attached to the hook 19, led over the hook 20 or the" pulley supported thereby, and its other end secured to the breakable member 24 which in turn is secured to the hook 18 on the window sill.
The breakable member 24 is preferably of such construction that it will break when weakened by moisture, in the event of a rain storm, or upon combustion, in'the case of a nearby fire.
When the parts are positioned as shown in Fig. 2, the member 21 and the member 24 are under tension, and if the member 24 should break, as described, the sash 14 will fall freely under the action of gravity until those portions of the flexible members 15 between the upper part of the sash and the clamps become taut, and will continue, by reason of the inertia so acquired, tomove on to closed position, the force of the fall being broken by reason of the fact that the sash is connected to the weights 13.
It will be apparent that if the flexible members 15 are sash cords, knots may be made therein instead of using clamps, but it is desirable that clamps be used to provide for ready adjustment on the members 15,
whereby the force with which the window will close may be easily regulated.
While .one embodiment of the invention has been shown and described it will be understood that various changes may be made in the details of the construction without departing from the spirit of the invention which is defined in the following claims.
The invention having been thus described,
what is claimed is t- '1. In a device of the class described, the combination of a window frame, a sash arranged for vertical movement therein, a counterbalance weight having a flexible connection with said sash, means for supporting said weight when the sash has been raised to one position, and means for supporting said sash when said sash has been raised to a higher position, comprising a breakable portion.
2. In a device of the class described, the combination of a window frame, a sash ar ranged for vertical movement therein. a counterbalance weight, a flexible member connecting said weight and said sash, means for supporting said weight independently of said sash when said sash is above a given position, and a flexible member for support- 111g said sash above said given position comprising a breakable portion and connected to the lower portion of said sash adjacent ranged for upward movement in said frame,
a counterbalance weight, a flexible member connecting said weight and said sash, means on said flexible member for supporting said weight independently of said sash to effect a lost motion connection between said sash and said weight when the sash is above a given position, and means comprising a breakable portion for supporting said sash above such position.
4. In a device of the class described, the combination of a window frame, a sash arranged for upward movement therein, means comprising a breakable portion for supporting said sash in a raised position, and a counterweight connected to said sash by a flexible member and operative when said sash has fallen to a lower position to counteract the momentum of the sash and lessen the effect of the force of gravity on the sash during further movement thereof.
In testimony whereofI afiix my signature.
THOMAS E. DAVIS.
