' DOOR-CHECK.

Specification of Letters Patent. Patented Sept 28 1920 Application filed February 27, 1920. Serial No. 361,811.

T 0 all whom it may concern Be it known that we, MoGARvEY E. TAT and Bonner M. TATE, citizens of the United States, and residents of Somerset, in the county of Pulaski and State of Kentucky, have invented certain new and useful Improvements in Door-Checks, of which the following is a specification.

Our invention relates to an improvement in door checks, the object being to provide a cheap and simple device consisting of a minimum of working parts, and yet effective in preventing the and noise occasioned by the slamming of a door.

A further object of this device is to provide construction that is applicable to both right and l ft handed doors.

To this end our invention consists of a resilient bumper attached to that side of a door jamb toward which the door swings in closing and which is so suspended as to be forced into position such that the .door in closing will be temporarily checked by it, then to swing by gravity into an inoperative position thus allowing the door to close.

Our invention is particularly adapted to light constructions such as screen doors, but it should be understood that we do not limit the application to doors of this character.

In the accompanying drawings Figure 1 is a frontelevation of a portion a door and jamb showing the application our improved door check.

Fig. 2 is a side elevation of a portion of a door jamb showing the method of attaching our improved-device andthe relation between the component parts.

Fig. 3 is a horizontal sectional view on the line 2-2 of Fig. 2, showing the operation of the device in full and broken lines, and,

Fig. 4 is a perspective view showing the application of our improved door check.

The door check conslsts of a main bar 1, preferably constructed from a single piece of spring wire having attached to its lower end a resilient ball or bumper 3 and having an intermediate coiled portion 4 for the re:

ception of a screw or nail 5 for fastening the device to the door jamb. The main bar 1 has at its upper end a forwardly projecting shaft-like portion terminating in a loop or eye 7. Tightly coiled around this forwardly projecting shaft-like portion is a spring wire 2, which is so bent as to form a triangular loop or abutment 8, two sides of which lie normallyin the path of the door. The free end of this triangular loop 8 is formed into a hook-shaped portion which engages the loop 7 at the upper extremity of the wire 1 for fastening the abutment in position.

The depth of the intermediate coiled portion 4: is such as to prevent frictional en gagement between the ball or bumper 3 and the jamb 6 and fits loosely on the nail or screw 5 to act as a pivot for the main bar 1, which, with the weight 3 forms virtually a pendulum. Two li ht brads or nails 9 are driven into the frame at opposite sides of the wire 1 to limit the movement of the pendulum, and insure the proper interception of the ball 3 between the door 10 and jamb .6.

.Vhen, with the above described construction the door 10 is swung shut, the inner edge of the door will strike the near inclined side of the triangular loop or abutment 8, thus forcing the same to swing out of the path of the door and allowing the door to continue toward a closed position. This lateral movement of the abutment will cause the hard rubber ball or bumper 3 to be interposed between the door 10 and the jamb *6, as shown in dotted lines in Figs. 1 and 3, the ball orbumper thus taking the shock which would ordinarily be received by the door jamb. Thedoor is accordingly thrown back by the resiliency of the rubber ball or bumper 3. During this slight recoil the bumper 3 assumes its normal or pendent position, thus allowing the door 10 to quietly close. In opening the door the action of the door check is substantially the same, but due to the lightness of the device and a simplicity in construction and operation, the action above described causes no appreciable effect.

In the accompanying drawings the device is shown applied to a door that closes toward the right side of the door frame. lVhen it is desired to apply this device to a door that closes toward the left side of the door jamb, it is only necessary to disen age the hook end of the triangularloop 8 rom the inclosed loop 7, and turn wire 2to the opposite side, again engaging the hooked end of loop 8 into the inclosed loop -7 as shown in Fig. 3, when the same will be locked in its new position.

We claim 2-- 1. A door check, comprising a substantially vertical rod having a pivot between,

its ends, a bumper carried at the lower end of said vertical rod,'and means apart from the bumper for engagement by the door whereby the bumper is at all times positively operated by the movement of the door into the path of the door as the latter is moved into a closed position. h

2. A door check, comprising a-substantially vertical rod having a pivot between its ends an abutment at the upper end of said vertical rod, and a bumper at the lower end of said vertical rod which during the movement of the door in closing is at all times forced into a position between the door and jamb to receive the impact-of the door.

3. A door check comprising a main bar having a pivot between its ends, a bumper at its lower end, an abutment at its upper end and in the form of a triangle, two sides of which normally lie in the path of the door when the bumper is in its normal or pendent position, said abutment being adjustably connected to the main bar whereby it may be extended either to the right or left of the ball supporting portion of the device as and for the purpose set forth.

A door. check comprisinga suitable bumper support adapted to be pivotally mounted on a door jamb, said support having an intermediate coiled portion forming a fastening element and also a pivot for the swinging motion of the device, and at its lower end a bumper, an abutment adjustably secured to the upper end of said bumper support which lies normally in the path of the door, and means for limiting the swinging'movement' of the entire device about its pivot. 7

5. A door check comprising a main bar having a pivot between its ends and weighted at the lower end, and at its upper end an abutment having abutting surfaces inclined reversely whereby it may be operated by the door in closing, said abutment being adjustably connected with themain bar whereby it may be reversed side to side to adapt the device to right and left hand doors 6. A door check comprising a main bar adapted tov be pivotally mounted on a door jamb having at its lower end a bumper which in its normal position lies out of the path of the door, and having at its upper end'an abutment presenting an inclined surface which liesnormally within the path. of the door and against which the door strikes in closing.

7. A door'check comprising a main bar having a pivot between its ends and weightedat its lower end, and at its upper end a forwardly projecting shaft-like portion terr minatingin a loop or eye, and an abutment pivotally connected to said shaft-like por-\ tion and having a free end bent to engage in the said eye or loop whereby the abutment may be shifted from side toside and locked in either position.

8. A door check comprising a main bar adapted to be pivotally mounted on a door jamb, having at its lower end a bumper, and at its upper end an abutment in the form of a triangle two sides of which normally lie in the path of the door and which due to the inclined surface presented is forced by the closing movement of the door out of the path of the door thus moving the bumper between the door and jamb.

9. door check comprising a main bar having apivot between its ends and having at its lower end a bumper and. at its upper end a forwardly projecting shaft-like portion, and an abutment having a portion journaling on said shaft-like portion and having a free end engaging with the shaftlike portion to lock the abutment in different positions as and for the purpose set forth,

10. A door check adapted to be pivotally secured to a door jamb comprising a main bar having an intermediate coiled portion for the reception of a suitable fastening means which acts as a pivot for the swinging movement of the device, a bumper attached to the lower end of said bar which in its normal or pendent position lies without the path of the door but which is forced into the path of the door by the lateral movement of the abutment attached to the upper end of said main bar and against which the door strikes in closing, and which upon the slightest recoil of the door assumes its normal or pendent position, and means whereby the said abutment may be shifted from side to side, and locked in either position.

11. A door check, comprising a substantially vertical rod having a pivot between its ends adapted to be pivotally mounted on a door jamb, a bumper at the lower end said vertical rod which in its normal position lies out of the path of the door, and an abutment at the upper end of said vertical rod which normally lies within the path of the door, and against which the door strikes in closing then forcing the bumper at all movements of the door toward a closed position between the door and jamb to receive the impact of the door.
