C A. SMiTHf DOOR CONTROLLER. APPLICATION HLED MAR- 22, I92].
Pdtentd Apr. 11, 1922;
TATiEfi QFFEQEO DOOR CONTROLLER.
mimic.
Application filed March 22, 1921.
To all whom it may concern:
Be it known that I, CrinLsin A. SMITH, a citizen of the United States, residin at Newark, in the county of Licking and btate of Ohio, have invented certain new and useful Improvements in Door Controllers, of which the following is a full, clear, conclse, and exact description.
An object of the invention is to provide a door having means whereby the same may be held in either open or closed position.
Another object of the invention is to provide such a device which will aid in opening and closing the door. This latter operation being performed by a spring whlch, after the door is partly opened or closed continues the operation until the door is brought to its final position.
Another object of the invention is to provide such a device which will firmly hold the door in either open or closed position and thereby prevent rattling of the door against the frame.
ther objects of the invention will be apparent from the following detailed description when taken in connection with the accompanying drawing in which;
Fig. '1 is a horizontal section through the door and frame, showing the controller in plan, the door being closed.
Fig. 2 is a similar view with the door open, and
Fig. 3 is a detail perspective View of a part of the operating mechanism.
Referring to the drawing more in detail, the numeral 1 designates a door frame and 2 the door. For the purpose of illustration the door and door frame of an automobile have been shown, the door being hinged as shown at 3.
Secured on the interior face of the door is the base member 4:. This member is rigidly held in place by means of the angular end members 5, which may be secured to the door by nails or screws. Tntegrally formed on the upper and lower edges of the base member are the ears 6, to which are pivoted the cam arms 7 and 8. The arms 7 and 8 are connected by the rod 9 which carries the roller 10. It will be noted that the arm 8 has an extension beyond the roller 10, and to this extension is pivotally secured the link 11 which is pivotally mounted at its other end on the door frame 1, as shown at 12.
A leaf spring 13 has a downturned end 14, which engages over the base member 4-. at one Specification of Letters Patent.
Patented Apr. 11, 1922.
Serial No. 454,542.
end thereof. The spring 13 is further secured to the base member by means of the bolt 15 and adjusting nut 16.
In operation, when suficient force is applied to the door the same may be opened against the pressure of the spring 13. In thus opening the door the link 11 will draw the cam arms and roller toward the left (Fig. 1) and thereby increase the tension in spring 13. After the cam arms have passed dead center the tension of the spring will force the door further open until it reaches the limit of its opening movement, and will then firmly hold the door in this position.
In closing the door a reversal of the above operation takes place. The link 11 forces the cam arms and roller in the opposite directlon against the tension of spring 13 until the dead center has been passed, when the spring will continue the closing operation and then hold the door tightly closed.
It is to be understood that while the present embodiment of the invention is shown as applied to an automobile door, this is to be construed as merely illustrative and not in a limiting sense.
While I have shown and described but a single embodiment of my invention, it will be apparent that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as defined in the appended claims, in which it is my intention to claim all novelty inherent in my invention.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A device of the class described including a hinged door, an arm pivoted thereon, a leaf spring engaging the free end of the arm, and a connection between the door frame and arm.
2. A. device of the class described including a hinged door, cam arms pivoted on the door, a roller journalled on the cam arms, a leaf spring engaging said roller, and a con nection between the door frame and cam arms.
3. A device of the class described including a hinged door, an arm pivoted thereon, a
.leaf spring engaging the free end of said arm, a connection between the door frame and arm, and means foradjusting the tension of said spring.
4. A device of the class described includ ing a hinged door, an elongated base member,
secured thereto, an arm pivoted on the base member a connection between the door frame and arm, a leaf spring engaging the free end of said arm, and means connected to said base member for adjusting the tension of said spring.
5. A device of the class described includ- 1 and means for adjusting the tension of said spring.
