Patented Jan. 27, 1931 ABCHIE CARL COOPER, OF HURON, SOUTH DAKTA Doon HOLDER Application led November 4, 1927. Serial No. 231,071.
which will appear as the description pro-A ceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understoodl that changes in the precise embodiment of the invention -herein disclosed, may be -made within the scope o what is claimed, without departing from the spirit of the invention.
Figure 1 shows in elevation, a device constructed-in accordance with the invention, mounted on a building which appears for the most part in section;
Figure 2 is a section on Figure 1;
the line 2-2 of Figure 3 is a section' on theline 3-3 of Figure 1, the door being open;
Figure 4 is a section ysimilar to Figure 2, the door being open;
The numeral 1 marks the franie' of a garage to which a door 2 is hinged at 3. An angle bracket 4 is secured to the inner surface ofthe door 2 and the horizontal lange'of the angle bracket has an upstanding stop 5. One
Figure 3, the
end of a link 6 is pivoted at 7 to the borizontal flange of the angle bracket 4. A ,carrying plate 8 is secured to the underside of the lintel 9 of the door frame. A lever 10 1s connected at one end, by means of a fulcrum'member 11, to the carrying plate 8. The numeral 12 marks a retractile spring.
`One end of the spring 12 is joined by ananchor 14 to the carrying plate 8, and the spring can swing on the anchor 14. A con- 11ection15 joins the opposite end of the spring 66 12l with the intermediate portion of thelever 10. The link 6 is oil'set as shown at 16, to accommodate the spring 12. A pivot element 17 joins one end of the lever 410 to the interlnediate portion of the link 6. VThe link 6 is provided at itsend with anupstanding detent pin 18 adapted to be received in a seat or notch 19 formed in one edge of the lever 10. A connection 20, such as an angle bracket, is pivoted at 21 to the link 6. A flexible element 22 is joined at one, end to the connection 20. The flexible element 22 is passed through a pulley block 23 mounted on one of the door posts of the frame 1, or elsewhere,
the exible element 22 being extended downwardly from the pulley block 23 within reach of an operator. When the door 2 is closed, the lever 10 is disposed above the link 6 in substantial alinement, vertically, with the link, the link being drawn over against. the stop 5, by the action of the spring 12. If the flexible element 22 be drawn upon, the lever 10 will -be swung, and after the connection 15 is carried past a line extended through the fulcrum member 11 and the anchor 14, the spring 12 will tend to open the door, motion being transmitted ,to the door by `way of the link 6. When the door 2 is open, as shown in Figure 3, the detent pin 18 'on the link-6 is received in the notch 19 of the lever 10, :90
the link 6 and the stop 5. Owing to this last described engagement (between the members 6 and 5) the door 2 will be stopped in a closed i position without using stop strips or other abutments on the door frame. Moreover, owing to the engagement between the parts .6 and 5, the lever 10 and the link 6 project 5 from the door 2 in a position at right angles i thereto, when the door is closed, and if desired, the device may be operated to open or close the door, by taking hold of the end 24 of the link 6. The flexible element 22, therefore, may be omitted in some cases, depending upon the particular structure wherewith t e device is assembled.
What is claimed is In a device of the class described, -a frame, a closure hinged to the frame, a link pivoted to the closure, a lever pivoted to the link,' means for ulcruming the lever on the frame, said means including a pivot on which the lever swings, interengaging elements on the link and on the lever, cooperating to hold the link and the lever unfolded and in 4approximate alignment to form a rigid brace which holds the closure positively in an open position until the folding of the lever and the link is'begun, the lever and the link being foldable into approximate alignment and into a position approximately at ri ht angles to the closed closure, and into suc relation with respect to the pivot element as to hold so the closure closed positively until the unfold-l in of the link and the lever is begun.
n testimony that I claim the foregoing as my own, I have hereto alxed m si ature.
