KNITED STATES PATnner Orrcn JOHN STEVENSOF WAKEFIELD, MASSACHUSETTS.
iMPRovEM'ENT IN Do'oR-cLosERs.'
Specification forming part of Letters Patent No. 174,165, dated February 29, 1876 application tiled J annary 29, 1876.
or door-casings, and are unsightly, and for that reason people of taste will not employ1 them; and then, too, the ordinary doorsprings work with an unequal force, not steadily, and the doors close with a slam, which is very objectionable to the majority ot' people. i
In my device, the door is closed by the action ot' a Weight raised by opening the door the weight is concealed, and when the door is closed none of the closing devices' arevisible; and when the door is opened only the cord connecting the weight and door edge is visible; and when opening the door the force to be overcome is an.equal one, and the force can be regulated to a degree just sufficient to close the door slowly but surely when released.
Figure l represents an open door provided with my improvement. Fig. 2 represents the weight and pulley and pulley-frame removed. Fig. 3 represents the slotted attaching-plate andFig. et a vertical section thereof on lines o: x; and Fig. 5 is a modification.
The door a is hung by means of hinges to the door-casing b, in any well-known manner, and within the casing b is a space to contain the weight c, its sustaining cord or connection d, and to receive the frame e and pulleys fg, only the plate g of the frame being visible when the door is opened. The connection ol isA provided with a knob, c', or knot, or hook, or equivalent, adapted to enter the opening j, in the slotted attaching-plate k, and pass downward therein, the width ot' the slot being contracted to hold the knob and prevent it drawing out from the slot of the plate. The plate at the lower end of the slot is recessed at front, as at l, andthe knob or knot rests on the projecting portions m ot' the plate.
the knob in che slitof the plate. The small pulley g prevents friction of theconnection d on the frame. When the door is completely open, having turned a little beyond one hundred and eighty degrees, the weight and connection then act to hold the door open. The
Weight will preferably be just sufficient to close the' door gently.
I am aware that it is not new to close a door by means of a weight,' but l am not aware that a concealed weight has ever been connected by a cord passed through the doorcasing at the jam andconnected with the edge of the door.
In Fig. 5 I show a hook, a, attached to the end ofthe connector d, and adapted to operate as the knob, but to insert or remove the hook its end 1 must be elevated.
'I claiml. The attaching-plate 7c, adapted to be connect-ed with the edge of the door, as described, in combination with the frame-pulleys f g mounted thereon, and with concealed weight and connection, adapted to be applied to the casing opposite the attaching-plate, all substantially as described.
' 2. The slotted attaching-plate k, provided with recess l, in combination with the connection d and knob z', to permit the door to be closed when the knob is removed from its connection with the plate of the door, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
