DOORCHECK Filed March l, 1928 @www `l l @VCA Patented Qct. 8, 1929 ELIZABETH BANNER, 0F ST. LOUIS, MISSOURI DOOBCHECK Application Med Iarch l, 1928. Serial No. 858,413.
The invention aims to provide an exceptionally simple and inexpensive, yet an eiicient check which may be easily inserted in a drilled opening in the hinged edgeof a door, and will serve to advantageousl cushion the final closing of said door, whic is particularly advantageous when spring means or other means are employed to effect the door-closing operation.
With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.-
Fig. 1 is a side elevation partly broken away and in section, showing the invention ap lied.
ig. 2 is an enlar ed horizontal sectional view on line 2-2 o Fig. 1, the door being only partially closed.
Iiig. 3 is la duplicate of Fig. 2 with the exception that it shows the door completely closed. i
The form of construction selected for illustration in the present application, may be considered as preferred on account .of its extreme simplicity, inexpensive nature and ease of application, and this construction will be herein specifically described, with the understanding that variations may be made within the scope of the invention as claimed. rllhe improved check embodies4 an outer, one-piece, metal tube 4 whichis of uniform diameter from 'end to end, said tube being open at one end but having a closure 5 at its other end. The numeral 6 denotes an inner, one-piece, metal tube which is of uniform diameter from end to end, is provided with one open end, and is closed at its other end by an integral closure 7 which is preferably considerably thicker than the tube Wall, the external face of the closure 7 being convex. This closure is formed with a central, air-escape port 8 from its inner to its outer side.
The two tubes 4 6 -are telescoped with each other and disposed in sliding contact to rovide anV elongated, hollow, cylindrical arrel which isof7 nature, said barrel being extensible under extensible and retractiblet-he influence of a coiled, compression spring 9 disposed within it, the ends of the spring belng positioned against the closures 5 7.
The cylindrical barrel above described, is ada ted for reception in an opening 10 dril ed into the hinged edge 11 of a door l2, the outer tube 4 being frictionally held in said opening while the inner tube 6 is free to slide. When the door stands open, this mner tube is projected beyond the hinged edge of the door under the influence of the spring 9. Asthe door nears closed position however, the closed outer end 7 of the tube 6 comes in contact with the door frame 13, arresting its movement, so that the outer tube 4 must slide toward the door frame as the door closes. This sliding movement is lresisted by the spring 9. Moreover, as the door nears its final closed position, the door frame gradually closes the air escape port 8, preventing rapid escape of the aircompressed in the hollow barrel incident to door closing. This air however can slowly .escape and ermit final closing of the door. By providmg a door check which thus depends not only upon the action of theI spring 9 but upon a pneumatic action, the final closing movement of the door is effectively cushioned and slamming prevented, even though a spring-actuated or other closing device be provided for the door. Such a device is diagrammatically illustrated at D in Fig. 1. v l
As the closure 7 moves from the position at which it initially contacts with the frame, to the position which it occupies when the door is completely closed, it must slide transversely to some extent upon said frame.. The convexedly curved formation. of the outer side of 'this closure greatly facilitates this sliding operat-ion and prevents any possibility of either binding the door against correct closing, or binding the' tube 6 in the tube 10 instead of permitting free relative sliding of these tubes. i
Preferably, I secure a wear-plate 14 to the frame 13 for engagement with the closure 7. This wear-plate is preferably inset in the frame and secured in place by screws 15,
but nothing except friction is necessary to anchor the tube 4 in the opening 10.
I claimz- A door check comprising an outer onepiece tube of uniform diameter from end to end, closed at one en d and open at its other end; un inner one-piece tube of uniform diemeter from end to end, closed at one end and open at its other end; the closed end-of said inner tube being externally convex, inherently rigid and having a central air escape port from its inner to its outer side; said tubes being telescoped in sliding contact with each other to provide a hollow extensible and retractable barrel adapted for insetting in a drilled hole in the edge of a door, :md spring means in said barrel for extending said inner tube beyond the above-named drilled hole, said convex end of the inner tube being adapted to rock u n the door frame a's the door closes, there y gradually closing said air escape port as the door nears closed position.
In testimony whereof fixed my signature.
