Description
July 27, 1948. c. E. GIBBS I STORM D OOR CHECK Filed Nov. 29, 1946 V 15: Gibbs 7 Charles Patented July 27, 1948 U IT D T E3" P TI NT FF QE sromvinooa canon 9 Charles'E. Gibbsjlvliddletown, Ohio I Application November 29, 1946, Serial No. 712,985 1 1 40mi s. (o1. 16-84) The present invention has todo with door ,checks; 'It is particularly designed for outer or storm door checks, but it will be understood that it may be used with any type of. door which itis desired to checkin itsclosing movements and avoid obj ectionable slamming.
Stated generally, the check comprises a piston cylinder, having, open and choked vents fixed to the door frame and having a piston and a piston rod. Securedto. one end of the cylinder is a bracket in which is mounted a rotatable shaft carrying a spring-actuated bell crank lever assembly, one arm of which lever engages the door and the other arm of which engages the piston rod., The bracket and cylinder are adjustable relative to each other, so as'to vary the leverage .ojf gthle' bellf.,;crank lever as may be desired. The piston rod extends completely through" the cylinder so as to ensure correct piston play and proper movement of the bell crank lever, and eliminate any tendency of the piston to jam in its reciprocations in the cylinder and interfere with the proper operation of the check.
In the drawings herewith is illustrated one physical embodiment of the invention, and in said drawings:
Figure 1 is a view in elevation of the upper portion of a door and door frame with the check in position, the door being in closed position.
Figure 2 is a view in top plan of the check on substantially the line 2--2 of Figure 1, looking in the direction of the arrows, the door being shown in partially open position in dotted lines.
Figure 3 is a longitudinal sectional view on substantially the line 3-3 of Figure 1, looking in the direction of the arrows, to show the bracket, bell crank, piston, and piston rod.
Figure 4 is a cross-sectional View on substantially the line 4-4, Figure 1, looking in the direction of the arrows.
Figure 5 is a detail view of the supporting bracket.
Figure 6 is a detail view of the bell crank lever shaft,
Referring to the drawings by numbers, the same numbers designating the same parts in the several views, a substantially U-shaped bracket I0 is provided, which bracket is adjustably mounted on a piston cylinder, as presently described. Mounted in slots l3 in the side wings of bracket [0 is a shaft having cylindrical portions M to permit it to rotate in the bracket. Said shaft is of non-cylindrical formation on either side of the cylindrical portions l4, shown shifting ofthe shaft. longitudinally in ,baajalih.
.One end of the squared portion 1 5 of the; shaft extends a considerable distance beyond, the ,side
wing of bracket in and receives the door contact lever 16 of the bell crank lever, which has a, square opening to engage the squaredend, l 5 of the-shaft,
so as to turn therewith, A 'tensioning spring 18 .outer, end the fork 20 has a stop. pin 23....which prevents arm ll from escaping from the are.
With this bell crank lever assembly it will be seen that the lever arms [6 and I1, tensioned by spring l8, will be held always in proper relation to the door and piston fork to respond to movements of the door.
At its inner end cylinder 24 is provided with an open vent 30, which permits piston 21 to move freely and without checking whenthe door is opened and the tensioning spring 18 moves the bell crank levers, piston rod, and piston toward here as squared portions l5, which prevents 66 under the impact of the closing door will be reand choked piston, will be retarded, slow down, movement of the door, and prevent slamming."
This checking action will be supplemented: to some extent by the tensioning spring which moves the bell crank lever to theirouter doorchecking position, but resists their return.
From the disclosure here made it will be seen that an effective door check is provided and one in which the parts may be readily made and "assembled; that the construction permits adjust- "ment-td meet varying needs, and when onceassembled, danger of derangement of the parts in use is minimized.
Such changes fromthe specific disclosure'hereinasamountonly to mechanical skill and fall within the terms of the'appended claims are to be regarded as Within'the range of the invention.
I claim:
1'. A' door' check comprising a piston cylinder "fiked tothe door; frame and having an "open vent at one end and a choked vent at the other end, I a bracket having'side' wings secured to'one end o 'saidcylinder, a shaft rotatably mounted in the 'sidefwings of said bracket, a'doorcontact lever mounted on said sh'aft, a compression lever mogmte tn saidfshaft between the bracket wings in'spaced'relation tos'aid contact le'ver; a ten- "signing spring tending to move said levers to door checking positions, a piston rod carrying a piston traversing said cylinder and engaging said compression lever, and a threaded sleeve on said rod adjustably to connect said bracket and said cylinder.
2. A door check comprising a piston cylinder fixed to the door frame and having an open vent at one end and a choked vent at the other end, a bracket havingsidewings secured to one 'endof; said cylinder, a shaft "rotatably' mounted in the side wings'of said bracket, a door contact lever mounted on said shaft, a compression lever "r'nounted on said shaft between the bracket wihgsin' spaced relation to said contact lever, a 15 "door checking positions, a piston rod carrying a pistontraversing said cylinder and engaging said tensioning spring tending to move said levers to compression lever, lugs on said bracket abutting "theend of said cylinder, and a threaded sleeve on said rod adjustably to connect said bracket lugs and said cylinder.
3. The inventionas defihed in eiaim- 1 urwhicn 'the side "wings of the bracket are slotted -tofireceive the rotatable shaft. z 4
4. The invention as defined in claim 2 in-"Which the cylinder abutting lugs 'project inwardly from the bracket wings in spaced apartjrelat-ion.
