Application filed August 24, 1909. Serial No. 514,401.

To all whom it may concern:

Be it known that I, JosnPH GREGAN, of"

enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in door checks and closers,the object of the invention being to rovide sim le means which will enable a oor to be he (1 open to any desired extent and to so construct said means that the same will operate automaticall to temporarily hold the door in open posltion but. which will yield upon the lapplication of comparatively moderate pres sure against the door to permit the closing of the latter.

A further object is to provide means on a door check for holding the door open and to so construct said means that the same can be readily adjustedaccording to the extent it may be desired to temporarily hold the door open.

. A further object is to rovide means on a door check for temporarily holding a door open to any desired extent, said means being so constructed and arranged that they can be thrown out of action and the device permitted to operate in the usual manner to close the door.

With these objects in view the invention consists in certain novel f atures of construction and combination's of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a: door check and closer showinthe aplplication of my improvements t ereto. ig. 2 is a plan view. Fig. 3 is a view partly in elevation and partly in section on the line m-w of Fig. 2. B igs. 4, 5, 6, 7 and 8 are views illustrating modifications.

1 represents the casing'of a door check and closer and 2 the spindle of the same, to which the lever arm 3 is secured,said lever arm being adapted for cooperation with the mechanism of the device and for connection with a door in the usual manner.

For the urpose of holding the lever arm 3 at any esired position and thus retainnow tobe described will be employed: The

cap or cover 5 of the casing 1 is provided with a lug. 6 which may be secured thereto or made inte a1 therewith and serve as a stop with. w ich a spring-pressed dog 7 carried by the lever armcooperates. The dog 7 in the form of the invention shown in Fig. 3, consists of a vertically movable plunger mounted in a boss or enlargement 8 on the lever arm and rovided at its lower end with two beveled aces 9, 9. A spring 10 is-secured at one end to the lever arm by means of a screw 11 and at its other end said spring is connected with the upper end of the dog or plunger 7 so as to normally press the latter downwardly so that its lower.

screw 12 passesfreely through a ho e in the lever arm and engages the sprin 10 intermediate the ends of the latter an the h of this screw serves as a stop to limit the upward movement of the spring.

From the construction and arrangement of parts above described, it will be seen that when the door with which the lever arm is connected is opened, the lower end. of the dog or plunger 7 will engage one end of the lug or stop.6 and will be forced upwardly and then ride over the top face of said do or stop. When the lever arm has move suflieiently to permit the dog or plunger to pass the lug or stop, 'said dog or plunger will be pressed downwardly. and become disposed behind the rear end of the lug or.

stop and thus the door will be held in open position. By applying comparatively moderate pressure to the door, the engagement of the beveled face of the dog or plunger 7 with the lug or stop 6, the'said dog or plunger will be caused to riseagainst the resistance of the spring 10'and to ride over the lug or stop. The device is now free to operate to close the door in the usual manner.

In order that the door can be tem oraril y stopped at any desired position, it is necessary that provision shal be made to adjust the lug or stop 6. Such adjustment can be readily effected by turning the cap or cover of the casing and for the purpose of retainbig the cap or. cover 1n any position to l which it may be adjusted, I provide av dog '13 carried by one end of a spring 14 secured to the rim of the'cap or cover,said dog passing freely through a hole in the rim of 'the cap or cover and adapted to ent'er any one of a series of perforations 15 around the upper end of the casing 1. I d

When it is desired that the door check and closer shall be operated in the usual manner without being temporarily held open, the dog or plunger 7 may be thrown out 0t action so as not to cooperate-with the lug or stop 6 on the cap, by loosening the.

screw 11 which connects the spring 10 with the lever arm.

Insteadof making the lockingdogin the form of a plunger as above described and locating the spring which operates the'dog, on top of the lever arm,'-said s ring may be secured to the under face 0 the lever arm, as shown at-16 Fig. 4 and the free end of this springprovided with a dog 17 to co- 0 eratewith the lug or stop on the cover of t e casing. V a Other means than those above described for efl'ecting adjustment of the stop or lug 6 may be employed. Thus in Fig. 5 the cap or ,cover is provided in its flanged poror cast integral with tion with a series of notches 18vwith any one of which a locking dog 19 attached to the casing 1 may be made to engage.

In Fig. 6 the lug or stop'is located on aplate 20 which is mounted upon the cap or cover of the casing and adjustably secured thereto by means of a pin 21.

In the form of the invention shown in" 7 the cap or cover of the casing is provi ed with a number of notches 22, into any one of which the dog or plunger carried by the lever arm may engage and thus hold the door at any desired open position, and in Fig. v8 I have reversed the-- construction shown in the other figures, that is to say I have secured the spring arm 10 to the underside of cap 5, with the spring pressed dog 7 carried on the free end of the spring and projecting upwardly through a hole in the cap to engage a In or stop 6* fixed to ie underside of the lever arm.

It is evident thatchanges in the constructionjand relative arrangement of the several parts might be made without avoidingamy invention and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but,-

Having fully described my invention what -I claim as 'new and desire to secure by Let- Y ters-Patent, is,

1'. In a door closer, the combination with a casing,'and alever arm, of a yielding device including a dog carried by one of said parts and engaging a shoulder on the other part whereby the door may be yieldingly held in its open position, and means for adjusting the tension of said yielding device hol .stop to temporarily lock the lever arm the whereby the pressure required to close the door may be adjusted and regulated.

2. In a door closer the combination with a casing and a lever arm, of a yielding device including a dog carried by one of said parts and engaging a shoulder on the other part for yieldingly holding the door open, and means for changing or adjusting the position of the shoulder with relation to the yielding: device, the construction of the shoulder and yielding device being such that a sufiicient pressure applied to the door will cause the yielding device to ride over the shoulder and thus permit the door tobe closed. a

3. In a door closer, the combination with a casin having a stop, a rotatable device and a ever arm connected with said rota table device, of a spring armsecured at one end to said lever arm, with itsfree end adjacent the casing, and a stop carried by the free end of said spring arm and cooperating wit the stop on the casing for yieldingly the door in open position.

4. T e combination with the caslng and lover armof a door check, of 9. lug or stop carried by the cover of the casing, means J for adjusting said cover to adjust the lug or stop, a spring pressed dog carried by the lever arm and cooperating with said lug or and hold the dooropen. I

5.' The combination with the casing and lever arm of a door check, said casing having a movable cover and-the casing having a series of perforations within the flange of said cover, of a lug or stop on the cover, a spring pressed dog carried by the flange of the cover and adapted to.engage any one of the perforations in the casing, and a spring pressed dog carried by the lever arm and cooperating with said lug or stop to temporarily lock the lever arm and hold the door open. a

6. In a dooricloser, the combination with the casing and a lever arm, of a yielding stop device carried by oneof said parts and enga 'ng a shoulder on the other whereby oor may be yieldingly held in open position, but may be closed by pressure applied to the door, and means for rendering the yielding locking device inoperative.

7. In a combined door closer and stop, a closer case, a spindle rotatable therein, a lever arm carried thereby, a stop adjustably mounted on said case and'arranged to be shifted to different positions angular-1y around the axis of said spindle, means for holding said stop in various positions of adjustment, and a cooperating stop-engaging member carried by said lever arm, one of said parts being yielding.

8. In a door closer, in combination, a case having a cap ortion, a rotatable spindle passing central y throughsa'id cap portion,

a lever arm mounted to-swing concentrically with the axis of the spindle, a stop adjustably mounted on the casing andarranged to be shifted to diiferent positions angularly around the axi sof said spindle, means for holding the stop in various positions of adjustment, and a cooperatin stop engaging member carried by the fiver am, one of said stop elements being spring pressed and ieldlng.

9. In a cor closer, in combination, a case having a cap portion, a rotatable spindle passing centrally through said cap portion, a lever arm mounted to swing concentrically with the axis of the spindle, a stop adjustably mounted on the casing and arranged .to be shifted to difierent positions angularly around theaxis of said spindle, means for holding the stop in various positions of adjustment, and a cooperating stop-engaging membercarried by thelever arm, a spring carried by the lever arm for impelling the stop engaging member also carried thereby.
