Description

I *aosmnscp i, ori' r'onano; onto To allwhomit mayconcern.

Beit knownthat I, JosIA Soon, a citizen of the United States, and a resident of Toledo, in the county, of Lucas and State of Ohio, have invented a certain new and use ful Door-Check; and I do hereby-declare the following tojbe a full, clear,and exact' description of theinventiomqsuchas will one able others skilled in the art to which it appertains to make and use the same, refer;

ence being-had to the accompanying-draw; ings, and to the characters .of reference marked thereon, which form apart ofthis specification. v My-inve'ntlon relates to door checks and it particularly relateslto a means for preventing the noise and injury oflthe slamming ofdoorseither glass doors; wooden doors or screen doors-particularlyithose that are closed by the action ofa spring-p1 i I 3 Theobjectpf my invention isftoovercome the defect commonlyifo'und in, door 'checks,

namely, thata, cushionmeansfis usually pro-: vided which holds the door-from the door jamb, preventing therebytight closing ofthe door by the spring of the door. :Myairivention-1-provides aflzdoor check which :per-

- mits the'door-to betightly closed and whichmay' beclosed by ai spring merely f f ficjent Strength to swing the; door to the her of forms of constructions and used for cushioning devices of different character; I have selected a construction containing the invention as an example to show that the in vention is practical and may be incorporated in a useful ,structure. The structure selected is illustrated in the accompanying draw- IDES Figure 1 of the drawing illustrates broken sections of a door jamb and a door to which the construction embodying my invention is connected. Fig. 2illustrat'es an end view of the door check. Fig. 3 illustrates the position of thech'eck when the door is closed;

1 indicates the door'casing, 2 is the door jainb and 3 is the door which is shown as open in Fig. 1 and as closed in Fig. '3. The door check is secured to the jamb 2 and in position such that it may be acted upon by the door 3.. It is supported in a housing 5 which may be provided with a downwardly extending lip 6. t It is secured tothe by means of screws 7 which pass through the lip 6 of the housing 5.

vided With-twoside walls 8, each of which i a diagonal slot 9iscut.1 V The cushion mem ber 10, that is, the check'itself, is support;

ed by a cross bar v11 in'the slots Q-ofithe sidewalls 8: The slots?) are slightlylarger than the cross bar ll'so as t OZallow move- 7 ment of the, bar 11 within the slot 9iand con;

,sequently limited movements of the cushion member 10.;1'The lower end' of .theslot 9'is provided with-an'angular'portion 12 which a extends substantially; vertical when the check is secured to the door frame whereby isformed a hump or corner 13 inthe-angu-z larside edgesofz th'e two-portions of the slot. The edge oppositefthehump 13 in each H slot :may berounded. -.;Thehump orlcorner linepassing through the center ofthei'cross" slowinci-ts closing moveme'ntz 1 a o The cushion member 10 may be" formed of any suitable material: and the shape thereof may: vary; In the form of the construction shown I have found :that it is preferable to make the cushion member 11 of rubber-or t a V zrubbel compositiomor of-similar material. The invention may be contained in a'num It,*ho'wever, may be formed of wood, having, if desired, cushion-parts. If made of rubber one end of the cushion device will comparatively 'of theangle is located about in'a horizontal cling to the surface of the door when it is;

force or swiftness and also it will cling'to brought toward the jambwith' considerable. V v

the end wall 20 of the casing when the door' V strikes it with suflicientimpact' to force the cross bar 11 along the. inclined slots '9.

When, however, the door strikes it while- I movingrtoward the ja-mb slowly the door will turn the .cushion memberv 10 without lifting the cross bar 11 from the angular portions 12 of the slots 9. The cushion member may also be'provided cushion member 10 within the casing 5 and jamb by the action of its spring.

In the operation of the device the; door 1 when open will permit thercushion member 11 to assume the substantially horizontal position indicated in Fig. 1.1 hen, how- 5 is proever, the door is'allowed to slam towith with a cam, surface 21 which will operate to tilt the considerable speed it will knock the cross bar from the angular port-ions in the lower ends of the slots 9 and the" nose 22 will cling to the surface of the door 3, and also the corner or end 23 will cling to the rear wall 20 of the casing, which will bring the bar to a stop and will prevent it from striking against the jamb.

The dOOr will be thrown back by reason of the rebound from the cushion device 11 and will then return toward the jamb more slowly. Meantime the cross bar 11 will fall back into the angular portions 12 of the slots 9. The door pressing against the nose 20 will rock the cushion member 11 and be drawn to the jamb 2 by' the action of its spring. An adjustable stop is located inthe under wall or lip 31 for varying the tilt of the cushion member 10 when the door is open to make certain the engagement of the cushion member with the door to prevent the doorstriking the jamb when it is moving swiftly toward the jamb.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I V r L 1. In a door'check, a casing having'an angular slot, one portion of the slot extending substantially vertical and the other portion of the slot inclined away from the door, a door engaging. member having apivot pin located in the slot,,the vertical portion of the slot adapted to permit rotary movement of the door engaging member when the door is closed slowly and to'shift to the inclined portion of the slot to permit engagement with the wall of the casing and the door Copies of this patient may be obtained for vwhen the door is closed quickly and to cause the returnof the pin to the vertical portion of the slot.

2. In a door check, a casing having an angular slot, an engaging member having a, a transverse pivot pin supported in the slot at the end thereof, the vertex of theangle of the edge of the slot being located on the side of the pin away from the door to yieldingly resist the movement ofthe pin from one part of the slot to the other part of the slot.

3. In a door check, a casing having an angular slot, one portion of the slot being substantially vertical and the other portion of the slot extending rearwardly away from the 'd0or,an'd from-the upper end of the other portion of the slot, an engaging member, a pivot pin for supporting the engaging member and eXtending through the slot, the movements of the pin and member being resisted by the angular edge of the slotaway from the door.

4'. In adoor check a casing having an angular slot, a door engaging member extending'from the casing, a pin for supporting the door enga'gingmember and extending through the slot and adapted to rotate in one portionof the angular slot when the dooris slowly closed and to engage the rear wall of the casing and the door when the pin is moved into the other portion of the slot by'the rapid movement of the door, the movements of thepin in the slot being resisted by the angular edge of the slot.

In testimony whereof, I have hereunto JOSIAH scorn signed my name to thisspeoific'ation.
