` J. J. REINHOLQ DOOR RETAINER Filaarch 10. 1923 ATTORNEY Patented Sept. 22, 1925i.

UNITED STATES PATENT OFFICE.

Doon RETAINER.

To all whom it may concern:

Be it known that I, JOHN J. REINHOLD, a citizen of the United States, and a resident of Marietta, county of Lancaster, State of Pennsylvania, have invented certain new and useful Improvements in Door Retainers, of which the following is a specification.

This invention relates to door retainers for holding swinging doors in certain positions against movement from anomalous causes.

The object of this invention is to provide a door retainer which can be conveniently adjusted to hold the door in various positions. This door retainer has no dependence whatever upon the floor of the room for its operation; and the door may be moved in either direction by simply applying` a slight excess pressure against it.

A further object is to provide adjustable means for limiting the movement of the latching lever so that the same cannot in advertently get to a position where it would be inconvenient to make adjustments.

This invention will be more fully understood and other objects will be apparent from the following description, talraen 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 my door retainer and represents one form of my invention.

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

F ig. 8, is a sectional view of Fig. 1, taken on line SW3.

Vith reference to the drawing, l is a bracket fixed to the door frame 3, through the screws 6. Forming part of the bracket eiare bosses 7 and 8 which carries the pin 5. The lever 10 is fixed to the pin 5 through the key pin 27. The flange 26 forms part of the lever 10 and is provided with a series of holes 11. Forming part of the boss 7 is a casing 9 which carries the stop pin 12. The stop pin 12 is normally held in engagement with one of the series of holes 11, through the spring 14e, and thereby locks the lever 10 against movement. The free end of the lever 10 is provided with a groove 15 which is adapted to receive the plunger 16. The plunger 16 is carried by the bracket 17 which is fixed to the door 18 through the screws 19. The plunger 16 carries a stem 20 which protrudes through the bracket Application filed March 10, 1923. Serial No. 624,162.

r17 to this stem is fined a set collar 21 which limits the upward movement of the plunger.

The spring 22 normally holds the plunger 16 in the uppermost position.

The manipulation of this device consists `0f pulling momentarily on the `ring 23 or cord 24, thereby withdrawing the stop pin 12 and again engaging it with any hole of the series 11, and consequently locking the lever 10 at the proper position for retaining the door 18 in the desired position; one of these positions being shown in light broken lines, Fig. 2. The door will then be held in this positionl against movement from anomalous causes so long 'as the plunger 16 is in engagement with the groove 15. kThe spring 22 resists inward movement of the plunger 16 sufficiently to produce this result. "The spring 22 however should be yieldingto such extent whereby the plunger16 will disengage with the groove `15 when ordinary pressure is applied to the door by a person passing through the same in the ordinary manner. The edges of the lever 10 are turned upward as shown at 25 to per mit easy entrance of the plunger 16 into the groove 15.

To render this device inoperative for an indefinite period it is only necessary to en gage the ring 23 with a nail or hook fixed to the door frame in a manner whereby the stop pin 12 is withdrawn and held fromV engaging any of the holes 11. This may be done when the plunger 16 is engaged with the groove 15, in which event the lever 10 will move with any movement of the door; or if the plunger 16 is not engaged with the groove 15 the lever 10 may rest in any posi tion, but preferably at the eXtreme open position of the door.

There may be certain times when the door cannot be opened to the full extent, for instance, on account of there being a piece of furniture located against the wall along side the doo-r, as shown at 26 in light broken lines; this piece of furniture would limit the opening movement of the door, but not the movement of the lever 10. Under such circumstances if the lever 10 should inadvertently get beyond the opening limit of the door, it would be inconvenient to adjust the lever, because ordinarily it is beyond the reach of the average person unless they stand on something in the nature of a chair or step-ladder. Therefore to avoid a condition of this kind means are provided to Cil limit the movement of the lever l0 in this direction, as itollovvs The boss 7 is provided With an Xtension 29, around which fits a collar 30. lIlorming-part of the-'collar 30 is a lug 3l, adapted to engage with the lug 32 forming part of the pin 5." A Wing `yvhe're Vthelng 82 contacts with the lug 3l,

and'it is obvious that this point may be altered by turning the collar 30 on the eX- tension 29. y

Since tlieidoor 1'8 sivinc's around a dif- `ferent centralpoint from that of the lever l0 is )vill-be thatvthe plunger 16 Will' have a"sliding action in the groove 15,

"if the same is permitted to remain therein While the stoppin 12 is Withdrawn and the door is in motion.' y'Therefore the groove l5 must beor suficient length to accommodate tothe -full eXteiit v,the sliding movement produced-When the door yis fully opened, and

also fork tlliepurpo'se of assuring that there Twill be a groove present to engage with the plunger I6 regardlessv of the position in Which thellever 1Q mightbe locked.

Having thus 'described my invention, what .I claim and desire' toy secure by Lettersy Patent is as Jfollows: y

l. In a door retainer comprisinga bracket,

a lever pivotally secured to said bracket, means for locking said lever in various positions to said bracket, and a latching device for connecting'the end of said lever to the door, said latcliing device being spring pressed and yielding to permit disconnection of said door from said lever end when a marked 'effort is applied in moving said door.

2. In a door retainer comprising a bracket, a lever pivotally securedto said bracket, means for'locking said lever in various positions to saidbracket, means whereby the end of said lever may b-e latched to the door .and hold the same against movement from ordinary anomalous causes, and means for limiting the movement of said leverin a direction 'to correspond to the opening movenient of the door.

In a' door retainer con'iprising a bracket, i
