Specification of Letters Patent.
DOOR.
Patented J an. id, i911.
Application filed April 14, 1909. Serial No. 489,904.
To all whom it may concern:
Be it known that we, JOHN BRUNZWICK, a citizen of the Austro-Hungarian Empire, and T'TERMAN C. Err-mans, a citizen of the United States of America, both residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Doors, of which the following is a specification.
"Our invention relates to improvements in doors.
One of its objects is to provide improved means to close the joint between the door and the floor frame or floor at the bottom of the door.
Another object is to provide improved, simple, and efiicient mechanism whereby this result can be accomplished.
It further consists in certain details of form, combination and arrangement, all of which will be more fully set forth in the description of the accompanying drawings in which:
Figure 1 is a plan view of the front of an ice-box showing a door in the closed position and provided with our improvements. Fig. 2 is an enlarged detail view showing our improvements in end elevation with the door in the closed position. Fig. 3 is a view similar to Fig. 2 showing the position of the parts when the door is partly open. Figs. i, 5, and 6 are detail perspective views of parts of our improved mechanism.
In the construction of ice-boxes and other rooms and compartments of a similar nature in which it is desired to introduce and remove articles by means of trucks, it is desirable to have a smooth and level floor at the entrance, unobstructed by a threshold or weather strip. It is also desirable when the door is closed to have the jointat the bottom of the door tightly closed to avoid an air passage beneath the door.
As illustrated in the accompanying drawings A represents an ice-box or cold-storage room.
13 represents the door giving access thereto, said door being hinged at Z) and latched at Z). A level floor G is preferably extended from outside to inside the box beneath the door.
D represents a vertically movable section suspended across the lower portion of the door by means of parallel links E which insure that both ends of section D shall move toward and from the floor in equal ratio.
F represents one or more guides which permit the section D to move vertically to a limited extent, and serve to hold section D against the face of the door B.
On the side of the door frame which carries the latch, or to and from which the door swings we provide or attach a bracket: G having a cam slot 9 formed between two projecting arms or lugs f. This cam slot is engaged as the door is closed by the crossbar or T-head 7a of a bracket H carried on the end of the section D which serves to force the section D downwardly and finally when the door is fully closed brings the lower edge of section D firmly into contact with the floor, thus completely closing the joint between the bottom of the door and the floor.
K represents a latch member which is hinged at 7;: to a bracket L attacl'ied to the door The lower end of member K divided into two arms k 7;? which span the shank of the bracket H, with the curved or hooked portion of said arms 71 in position to engage the cross-bar or head it of bracket H, and thereby to hold the section D in the raised position whenever the door B is in the open position. The weight in the latch member K is preferably so distributed that said member normally tends to assume a position to engage and hold the cross-bar h. The hook 76 is longer than hook 7.3 to insure engagement with the head 77, as it leaves the slot 9'.
As the door is being closed and the bar 7L enters the cam slot 9, the lower end of one of the arms 70 or 70 of the latch K engages the lug g which tilts the member K to disengage the bar it from the arms 70 70 as indicated in Fig. 2, and the latch member K remains in the tilted position until the door is again opened when the section 'D is raised by the action of the slot 9 on the bar it, and as the bar it emerges from the slot g it is caught by. the arms 70 70 and held in the raised position until the door is again closed.
e preferably secure a piece of rubber (Z or similar yielding material to the lower edge of section D to be pressed by said section into contact with the floor to compensate for any inequalities in the floor. The several components of our improved mechanism are so shaped as to be applied either right or left hand.
The mechanism herein illustrated and described is capable of considerable modification without departing from the principle of our invention.
Having described our invention what we claim is:
1. In a mechanism of the character indicated, a door frame, a door hinged thereto, a movable section carried by and supported relative to said door by links pivotally attached respectively to said door and movable section, a stud carried by said movable section, a bracket having a downwardly inclined slot carried by said door frame and adapted when the door is closed to engage said stud to press said movable section into contact with the floor, and a latch carried by said door and adapted when the door is opened to engage said stud as it leaves said slotted bracket, and to hold said movable section out of contact with the floor until the door is again closed.
2. In a mechanism of the character indicated, a door frame, a door, a movable section carried by said door and supported relative to said door by links connecting said section to said door, a latch member carried by the door to engage and hold said movable sect-ion in the retracted position when the door is in the open position, and means carried by the door frame to disengage said movable section from said latch and to move said movable sect-ion to an extended position when the door is closed.
8. In a mechanism of the character indicated, a door, a door frame, a movable section carried by and movable relative to said door, a latch member adapted to engage and hold said movable section in its retracted position when the door is open, and means stationarily located, adapted to engage said latch member to release its engagement with said movable section and to shift said movable sect-ion to its extended posit-ion when the door is closed.
4. In a mechanism of the character indicated, a door a movable section carried by said door, substantially parallel links connecting said movable section to said door, a latch member adapted to engage and hold said movable section in its retracted position when the door is open, and mechanism to disengage said movable section from said latch member and to shift said movable section to its extended position when the door is closed, and to reengage said movable section with said latch member when the door is again opened.
In testimony whereof we have afhxed our signatures in presence of two witnesses.
