Application fiIed Mar ch 10,1923. Serial No. 624,159.

To all whom it may 00 m. 8'

The object of this invention is to provide i a device whi ch is adaptable'to stop theldoor at predetermined points throughout'f'its swinging movement, and ;to provide means in combination therewith whereby the" door point. A furtherobject is that the door is free to be moved open at all times, but can not be" closedbeyond said predetermined point without special manipulation of said device. y v

Other objects will be apparent from the following description, taken in connection with the accompanying drawing, forming a part hereof, and in which similar numerals refer to similar parts throughout the several views.

Fig. 1 is a front elevation of a device repwhere the bracket end 14 contacts with the same. i

Thelever 12 in effect forms a stop to limit 7 resenting one form of my invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a plan view showing the door partially open.

Fig. 4 is a sectional view taken on line 44 of Fig. 3.

With reference to the drawing, 3 is a bracket fixed to the door frame4, and carries the pin 5 through the bosses 6 and 7. Fixed to the door 8 through the screws 9 is a bracket 10. Carried by the pin 5 are levers 11 and 12, adapted to contact with the end 14 of the bracket 10 as shown.

Surrounding the pin 5 and interposed between the lever 11 and collar 26, is a spring 15, and is adapted to normally move the lever 11 in the direction indicated by arrow 16, thereby normally closing the door. The

collar 26 is fixed to the pin 5 through the wing head screw 27, and by releasing this screw and rotating said collar on the pin 5, the tension of the spring 15 may be regulated. I

The lever 12 is fixed to the pin 5 through the key pin 17; said lever also carries a flange 18 which is provided with a series of holes 19. A casing 20 forms part of the boss 7 and carries the stop pin 21. A spring the stop pin 21 inengagement with anyyof the-several holes .19.

It is apparent that the stop pin be disengaged with. any hole 19 by pulling the ring 23 or. the cord 24, and when so disengaged this device has no effect in closingwthe door; the leversfll and 12'theniinove with the door as the pin 5 freely turns in the bosses 6 and 7. I

With :the stop pin- 21 engaged with the hole as shown in the drawing (full lines, Fig. 2), the normal action of'sp'ring 15,

through the lever 11 and bracket 10, will completely close the door. 8; the pin 5.1mder this condition is not; freeto turn because the same is fixed to the lever 12 through key pin 17 ,"anduponI-opening the door 8 the lever 12 remains stationary, and as the lever 11 turns on the pin 5 it is counteracted by vthe normal action of. the springfll5. -Under these same conditions the door 8 will always close under theinfluence of spring 15, until the end 14 of the bracket 10 contacts with the lever 12.. Therefore if the lever 12.is fixed in the position shown in light broken lines Fig. 2, and full lines Fig. 8, the

door cannot be closed beyond the point the closing position of the door, and the position of this lever may be altered by engaging the stop pin 21 with any of the several holes 19. The lever 11 in effect serves as a closing means for the door, and always moves with the door. If the lever 12 is looked through the stop pin 21, the lever 11 can move only against the action of the spring 15'; but if the lever 12 is not locked, both levers 11 and 12 moves with the door.

To render this device ineffective for an indefinite eriod it is only necessary to engage the rlng 23 with a hook or nail fixed to the door frame in a manner whereby the stop pin is released from the holes 19'.

To relieve the strain on the stop pin 21 when the bracket end 14 contacts with the lever 12 through the closing operation of the door 8, the lever 12 is preferably constructed of a flat spring steel strip 28, which is sufficiently yielding to ease the shock applied thereto when the door closes at high speed.

On certain occasions it may be undesirable that the door automatically closes, but

22 is provided and adapted 'to normally hold 7 desirable to retain that particular feature wherein the door is held in a fixed partially open position. In this event it is necessary to release all tension on the spring 15 by opening the wing head screw 27, and allow the lever 11 to position itself as it will, or as shown in Fig. 3; it is then ineffective in closing the door 8. Then the lever 12 should be fixed to limit the closing movement of the door in the usual manner, then to fix the door 8 so that it cannot open through anomalous causes I provide a latch 29 which is carried by the bracket 10 and pivoted thereto through the pin 30. A spring 31 is provided to normally hold said latch in the position shown in Fig. 4. Reference is here made to my copending application on door retainer, Serial No. (321,162 filed March 10, 1923.

The beveled end 32 of the latch 29 is adapted to contact with the rear side of the spring strip 28 and to cause the latch 29 to move downward against the action of the spring 31 when suflicient pressure is brought against the door 8 in the direction indicated by the arrow 33. This device permits of freely opening the door at will, but holds the same against such movement which might be caused by slight air draughts.

When the door is being closed, or in other Words being brought back to the limited closed position, the spring strip 28 will ride on the surface 3 1 of the latch 29, pressing the same down against the action of the spring 31 until it again latches between the bracket end 14 and end 32 of latch 29.

the combination with a bracket, of a lever pivoted on said bracket, locking means arranged to hold said lever at various positions relative to said bracket, a second lever pivoted on said bracket, a spring arranged to normally move said second lever angularly in a direction towards the first said lever, and a shock absorber arranged to relieve the strain on said locking means.

In testimony whereof I afiix my signature.

JOHN J. REINHOLD.
