Application December 17, 1934, Serial No. 757,799 y 6 Claims.

My present invention relates to improvements in door closures, and has particular'reference to door closures attached to the bottom or top of a swinging door or window.

The particular object'I of my invention is to improve the construction of door closures so as to reduce to the very minimum air space between the various parts of the mechanism, which has een an objection to door closures made and marketed up to the present time, in which latter construction there is substantial air passing up and around the closure mechanism itself.

A further object of my present invention is to produce a construction in which leaf springs and the like, which are relatively soon distorted 'and become inoperative, are dispensed with, and to produce a door closure in which none of the parts are required to be replaced.

This' and other objects will be seen by an inspection of the drawings in the light of the speciiication.

In the drawings,

Fig. l represents an elevational view of a lower part of a door showing the door closure in closed operative position, partsof the said door closure being broken away;

Fig, 2 represents a longitudinal sectional view, with parts of the mechanism not shown;

Fig. 3 represents a cross section taken on the lines 3 3 of Fig. 2;

Fig. 4 is a cross sectional View taken on the lines 4 4 of Fig. 2;

Fig. 5 represents a cross sectional view on the lines 5 5 of Fig. 2`;

Fig. 6 represents an enlarged View of the spring mechanism for returning the door closure in raised position; if

Fig. '7 represents an enlarged'view of the lever mechanism;

Fig. 8 representsva plan view of the actuating means taken on the line 8 8 of Fig. 2;

Fig. 9 represents a cross sectional View taken on the line 9 9 of Fig, 2;

Fig. 10 represents an end view of the lower part of the door and the improved door closure inserted within said door; and

Fig. ll represents an end view of the lower part of the opposite edge of the door showing the hinged connection in cross section.

Similar reference characters are applied to the relative parts in the various figures shown, in which I represents the door casing, 2 the door itself, 3 the door-sill, 4 the adustable rod, 5 the lpivoted connection of said rod to the lever 8, 'I a cross bar which is welded or otherwise attached to a U-shaped casing 8, said cross bar being pivoted to the lever 6 at 9, Ill represents a roller pivoted at II to the lever 6, I2 is a metal plate von which said roller I0 makes contact when the lever is in the depressed condition, said plate being connected at I3 to the longitudinal extending felt retaining member I4. I5 represents the pin connection of the coil spring I6, which spring is connected through a hole Il in the lever I8, said ievei` being journalled to the cross bar 8 by the pin I9, said lever I8 having a recess 28 for cooperation with the pin 2|, which pin extends transversely Aacross the felt retaining member I4, said felt retaining member I4 being braced by means of a series of pins 22, extending from side to side of said felt. retaining member I4. 23 represents a screw inserted in the door casing, 24 represents a metalplate through which the end of the rod 4 projects at 25 in alignment and for-making contact with the screw 23. 26 represents the felt or other compressible member. 21 represents a stem for reinforcing the connection betweenthe threaded portion 28 of the

rod

4, 29 the place at which said rod 4 enters the bifurcated arm 38. 3l represents the hinge of the door, 32 the end plate for the door closure and 33 and 33A the screws for attaching the plates to the door. 34 are the screws passing through the U-shaped casing 8 by which the door lclosure is attached to the door. Any other suitable means, however, may be used for permanently aflixing the door closure to the door, such as inserting U-shaped lugs in the

metal plates

24 and 32 toserve as a support for the vertical part of the U-shaped casing 8.

The rod 4', threaded as shown at 28, passes thru a threaded opening in the bifurcated arm which arm makes the connection with the pin 5. The stem 27 serves to reinforce the connection between the threaded part 28 of the rod 4 and the bifurcated arm 30, and vto lessen the tension on I the threaded part 28 as pressure is applied to the end of the rod 25 upon opening and closing the door or window. Said end 25 is recessed to permit said rod to be turned so as to adjust the depth to which the lever 6 will extend upon the rod 4 being pressed inwardly. To carry out this adjustment most eifectually the pin 5, when the lever 6 is in raised position, is located, as to vertical alinement, nearer the rod 4 than the pin 9 as clearly shown in the drawings.

Figures 1 and 2 show the structure in operative position, i. e. with the felt pressing against the lower part of the door-sill, the door being in closed position. When the door is closed the rod 4, pressing against the screw 23, is forced forward, thus forcing the lever 6 downward against the plate I2 and thereby forcing the felt retaining member I4 downward and thus closing the aperture between the doorA and the door-sill. This lever 6 functions only for the purpose of thus depressing said felt retaining member. When the door is openedand the friction between the rod 24 and the screw 23 is removed the lever I8, being actuated by the spring I6, raises the said felt retaining member I4 to which it is pivotally connected by means of the pin 2|, said lever I8 thus functions only to return the felt retaining member in raised position. To reduce friction either one or two rollers-on each side of said lever 6 may be used. Both of said levers 6 and I8 pivotally mounted on the cross bar l are situated within the contour of the felt retaining member I4, said felt retaining member thus being in longitudinal alinement and in close proximityv with the sides of the U-shaped casing 8.

There has been a serious objection to the structures heretofore marketed by reason of the fact that parts of the actuatingV mechanism have been attached to the outside of the felt retaining mem,

ber, with the result that a considerable air space resulted between the U-shaped casing and the felt retaining member and thus the efficiency of the door closure has been seriously impaired. With my improved construction this air space is eliminated and the retaining member is throughout the longitudinal length of the door closure in as close proximity to the lll-shaped casing as is possible without friction between the two members.

Also in structuresthat are at the present time on the market, the structure necessitated the use of one or moreleaf springs, which soon become inoperative by use and even by the initial insertion of the weather strip in the door, and frequently have to b'e replaced. With the construction herein shown this serious objection is obviated.

As will be observed by an inspection of the drawings, particularly theslot 2l), the felt retaining member is removable from the remaining portion of the device, which is an added advantage of applicants structure; vfor when the felt retaining member must be replaced, it is not necessary to remove theentire casing from the door but only the retaining member maybe removed, a new felt may be inserted in the retaining member and thereupon the same may be reinserted in the casing.

While I haveshown my improved invention inserted in a wooden door yet itis perfectly obvious that the invention. may be enclosed in a metal housing and attached to either the front or back Y of a Vmetal door without any change of structure y or function.
