Dooncnncx.
sppucatiqnlmed Aprile@ 1923'. `serial No. caress. i
E State of TeXas, have invented a new and a specification. 4 c ,c
This invention. relates to `a door-check, one of its objects beingto provide acheck whichwill allow a door to swingy rapidly for a portion of its distance of travel after which it will be automatically retarded until the door nearly reaches its closed position at which time the door is` released automatically and is allowed to close tightly against the jamb. i y, Another object is to provide novel friction means for retardingv the movement ofthe door, there being meansfor automatically coupling the door toand uncoupling it from the friction lmeans during the movementjof thedoor toward its closedposition-; A further object is to provide a door check which is simple and compact, canl be applied readily, and has means whereby it can be easily adjusted to varyJits resistance kto the actuationy of the door.`
With the foregoing and view which will appear .as ythe description proceeds, the invention consists of certain novel details of construction and combination of parts which will be hereinafter more fullyA described and pointed out inr the claims, it being kunderstoodthatv .various changes may be made in the construction and arrangement of the parts without departing from the spirit of the-invention as claimed. In the accompanying drawing the preferred forms of the invention have l been shown. f Tn said drawings: Figure 1 is an elevation ofthe check, a portion of the door and Ajamb being shown in elevation and section respectively.`
Figure 2 is an elevation of the parts, the door being shown open. c v
Figure 3 is a plan view showing the door closed as in Figure 1.
Figure 4 is a plan view showing the door open as in Figure 2. l i v c Figure 5 isa section on line 5-5 Figure 2. Figure 6 is a plan view showing a *modified construction. y
Referring to the figures by characters of reference A designates a portionqof a door useful Doorcheck, of which the following is other objects in jamb and B designates a portion of a door connected to the jamb c by lone or more hingesC.` y
y.The check` includes superposed attaching plates l and 2 adapted to be fastened to the jambAHby screws 3 or the like extending through `slots `4 whereby the plates can be adjusted toward or ,from each other. .Each platehas a `wing` extending at right angles therefrom,-the two` wings being `of the same contour `and ysupporting a central clamping bolt 6 engaged by nuts I one of, which bears downwardly on the upper wing 5 `while the other .bears upwardlyV against the lower wing 5.,y yThe greater kportion ofthe .pes ripheries ofthewings are concentric ywith the bolt` .63 but atintermediate `points `these `peripheries are out away as shown at `8 to provide recesses.
Mounted for rotationy on the bolt 6 and between the wings `5 is a ratchet disk 9 the cessively withinvthe recess-8.` Those teeth not exposed in theyrecess are positioned inwardly from the peripheriesA ofthe wings as will be apparent by referring 15o/Figures 33nd4hc r i'. i
An arm 10 havingajforkedend 11 straddles kthe wings 5 and frictionally engages the exposedy surfaces ofthe respective wings. 8
The arms of the forked portion 11 are offset as shown at 12v so as tobridge the nuts 7 and pivotally engage bolt 6. Thatr end of the arm remote from the fork is `connected by ,toggleflinks 13 toa bracket Mattached to the doorfB. LA light springl is` connected tothe bracket 14 andl bears against `tion 17 on, plate 1 and this spring is def signed to pull the doorto closed position when -a hingevspring or other closing means is not used. This spring is adapted to eni gage a sleeve or roller 18 carried by one end portion ofthe bolt 6. i
It is to be understood that the wings 5 engage the disk 9 with sui'icient pressure to frictionally retard the rotation thereof. This disk is adapted to be actuated by` a spring .pressed dog 19 mounted `within the forked portion of thearm 10 andfnormally pressing against the peripheries of the wings 5. Vhen `the door is fully open and the part-s are posillO tioned as shown in Figure l1 the dog 19 bears against the peripheries of the wings and is held thereby out of contact with the frictionally held disk 9. At this time the spring 16 is under tension or, if `spring 16 isnot used, the spring of the hinge is under tension. Thus when the open door is released the spring will swing it toward closed position. During the greater portion of this movement the dog will `slide freely along the peripheries of the wings `but as the door continues to move, dog 19 will move into `the recesses 8 and engagey one of the, exposed teeth of the disk. The dog will thus thrust against the disk and rotate it and as thedisk is held frictionally between the wings the movement of the door will be retarded.: This retarded movement will continue untilV the door is almost closed at which time the dog will be deiiectedby the walls ofthe recesses 8 so as to pass outof engagement with the disk. As the door is thusrelieved from the retarding action of the ydisk its actuating spring will move the door the short remaining distance so that said door will fit snugly against the jamb without slamming.
Spring 1.6 is not always used but it isa desirable portion of the structure because of its action while ,closingthe door. t When the dooriscompletely open the spring exerts a direct pull from one end to the other and this pull continues until the spring comes yagani'st the 1sleeve or roller 18. At `this time the spring'bends and acts as a cushion lto retard the closing of the door by reducing the power exerted, thus rendering thefriction wings and disk more efficient. A
Under some conditions it is desirable to have the arm of the check detached from the door. t' Such a structure has been illusytrated in Figure `6. When this structure is used a roller 20 can be carried by the arm Yfor engagement with the door and a spring 21 can be connected to the armvand to the plate 1 for the purposevof'holding the roller constantly pressed against the door. Y
It is to be understood that the spring 16 need not be used if the door is provided with spring hinges.
