Specification of Letters Patent.

Patented Apr. 30, 12312.

Application filed June 9, 1911. Serial H0. 632,123.

To all whom it may concern:

Be it known that I, Fnnnmucn Scrum)- CALL, a citizen of the United States, and a resident of Cincinnati, Hamilton county,

State of Ohio, have invented certain new and useful Improvements in DoonLocking Means; and I do declare the following to be a clear, full, and exact description of the invention, attention called i0 the drawing, which accompanles this application and forms a part thereof.

This invention relates to new and useful improvements in door-locking means, particularly intended for use on doors for re' frigeratozs and cooling rooms. Doors of this kind are usually provided with beveled edges which are fitted to seal: against a correspondingly shaped jamb, the object being to obtain a closure as near air-fight as is possible. To seat such a door properly, requires a certain amount of pressure and it also requires a certain effort to releasesuch a door when closely fitted from its seat for the purpose of opening it.

My invention consists of a construction wheneby in addition to the mere locking device, manipulating means are provided which permit the door to be tightly forced into closing position and whereby it may also be quickly released for opening.

In the following specification and particularly pointed out in the claims at the end thereof will be found a full description of my invention, together with its operation. parts and construction, which latter is also illustrated in the accompanying drawing, in which:

Figure I. shows a innit-view of a door whirl: may be the door of a calling room, sealed and hold in closed [)(blllflll by [he means provided by nu lint-"lion.

. mg means and as they appear in Fig. l, the

of the door only being shown. Fig. 3, 1s a a vertical sec-lion on line 8 -8 of Fig. 5 and ilhislnilcs means for door.

In the drawing 10 Indicates a door of positively locking the l a '2, i l'fllfill sa'lion of this door. Fig. 3, 5 is an enlarged horizontal section of the 0105- the kind here in view secured by hings 11 and fitted with its beveled edge 12 against a complementary jamb 13.

A is a keeper secured adjacent to the free edge of the door and B is a latch 0 tin inconjunction therewith. This late is ivotallv mounted in a housing C attach to the door opposite the keeper. It is maniculated by an angle-lever D, also mount in housing C by means of a pivot 14. At one of its ends it carries a pin 15, which occupies a slot 16 in the latch-and atits other end is a handle 17 for manipulation. That art of thelateh which projects beyond the musing is shaped to form two fingers 18 and 19 which co-aet with the keeper, one for chsing and one for opening of the door. If handle 17 is moved as shown in Fi 3, finger 18 bears against the inner side 0 the keeper and latch B becomes a lever and b means of its pivot and through housing re-acts against the door and forces the same hlpme to It; mt. filnfgethe handle is movedthns s ownin i .4, rIQbearsagainst e outer side 0? the keeper and by analogous re-action of the latch on the door pulls the same from its seat. In either case handle 17 may be used in the further manipulation of the door, that is to open itto the full extent required or to move it the other way. In order to hold the handle rigid on the door during (his time there is a locking pin 21 carried on an arm :22 and pivotally supported in an extension 0 of the housing and which pin drops into a socket 23 properly lo ated on the latch when the latter movs into the xsition shown in Fig. 4. The latch is thereby held immovable so that. finger 19 remains in a position in which it may again readily ro-act with the keeper when the door is being closed. This pin may drop into position by more action of gravity, or a spring may be added adapted to act upon arm '13 to urrvh-raie the action if found necessary. This aforesaid umction requirm a release of the lah-h from this lockin -pin, so that the former may resp nd to manlpu lalion of handle iii For such purpose the end of a rm 2'2 caused [0 pass over the inclined snrfure of a stationary can! ll which for mnn'cnienvc sake is provided at the upper end of-lhe hee x-r Fig. 6.) Manipulation from the other side of the door is made possible by means of a supplementary handle .25, connected to lover I) which it reaches through an openin 3G in the door.

For such purpose it; is slidahly fitted into a housing 27 which is flanged for attachment adjacent to the door. A screw 28 is provided in longitudinally fixed position within this housing upon which the keeper is sated. The outer end of this screw is accessible for manipulation by an implelnent,'so that the keeper may be correctly positioned for proper co-action with t e latch.
