Application December 23, 1944,"Sei'ia1No.56'9,564
An object of the invention resides in providing a door closer in which the operating parts are protected and in which injury .to the user is entirelylprevented.
Another object of the invention resides in constructing said lever U-shaped in form and channel-shaped in cross section to provide spaced flanges with a web connecting said flanges and situated at the outermost portion of the lever.
Astill further object of the invention resides in providing a door closer in which an opening is formed in the web-of the lever, said opening leaving asportion atthe-end of the web intact to provide a cross bar to which a spring anchored to the case may be attached.
.A feature of the invention resides in arranging the spring to operate in the opening in the lever.
Another object of the invention resides in constructing :theoutermost edges of the flanges at the locality of the opening in said web with notches adapted to engage studs extending inwardly from the side walls of the case and in further arranging said cross bar so that the spring, in addition to urging the closing arm K into closingposition, holds the lever in engagement with said studs.
Another object of the invention resides in-constructing the case with a tongue disposed at the open end thereof through which the lever extends, said tongue being disposed within the opening in said lever.
A feature of the invention resides in constructing said tongue arcuate in form and concentric with the pivot of said lever and in disposing said In the drawings:
Fig. '1 'is an levational view of a portion of a door frame and doordisposed in closed position together with a door closer with a portion ofthe same cut away and illustrating an embodiment of rny invention.
Fig .2 is a plan sectional view taken on line 2-2of Fig.1. I
Fig, 3 is a view similar to Fig. 2 showing the door partly opened and the closer in fullyopened position.
Since the construction and operation of swing ing doors is well known in the artya complete door-and frame have not'been shown in the draw- I ings, but only so much thereof as is necessary to illustrate the application-of my invention thereto. For this purpose, 1. have shown'a door frame It comprising'a jamb i l and a casing I2 connected thereto and offset with relation to the jamb to form arabbet ii. A door I 4 hingedly connected to the fiam'b I at a locality which would be to the right of the portion of the 'jamb illustrated in Figs. 1, 2=and 3. 'This door is adapted to move into and .out of the rabbet 1'3 and when in closed position, is' situated substantially-as shown in Fig. 2. The door is shown :in partly open position in Fig. 3.
*The door closer proper is indicated in its entirety by the reference numeral i5 and consists of a case 20 and a'lever '30'piv0ted to said case and operating to engage the door to close the' 'These'parts will now be described in vdesame.
tail. 7 I
The case 20 is constructed of sheet metal having two sides l6 and I1 and'a back 53 connected therewith. 'These parts arebent in the form of a -U, the case being-open'at the forward and end portions of the same. The walls it, H and 18 have ears 1-53, 22 and 23 projecting outwardly 29 is sdisposed'at the outermost portion of the lever '50 was to assist in concealing the interior.
operating parts of :the deviceand to prevent the formation of aconstruction bywhich the fingers of theoperator ;might be caught and injured.
The :flanges .21 and. 28 extend throughout both 3 of the arms 25 and 26 and are spaced from one another throughout their extent. Between the flanges 21 and 28 of the arm 26 is disposed a roller 3| which is rotatably mounted on a pintle 32 extending through and secured to said flanges. In like manner, a roller 33 is disposed between the flanges 21 and 28 of arm 25 and is rotatably mounted on a pintle 34 extending through and secured to the said flanges. The roller 33 serves as a trip roller for moving the lever 26 into operating position, while the roller 3| serves as a closing roller for engaging the door and moving the same into closing position as will be presently described in detail.
In the web 29 of lever 33 is formed an opening 35 which extends up to the flanges 21 and 23, leaving the outermost edges 36 of the flanges exposed. The said opening falls short of the end of the flange at the arm 35, leaving a portion 31 of said flange intact, which is bent inwardly to form a cross-bar disposed substantially at the interior edges of the flanges 21 and 28. In the flanges 21 and 28 are formed notches 38 which are adapted to engage studs 39 attached to and extending inwardly from the inner surfaces of the walls It and H of case 20. These notches extend through the edges 36 of the flanges 21 and 28 and permit of application of the lever to the studs 39 by movement of the lever inwardly into the case through the open forward portion of the same.
The lever 30 is held in engagement with the studs 39 by means of a tension coil spring 4| which is formed at its ends with hooks 42 and 43. The hook 43 is hooked over the cross bar 31, while the hook 42 is hooked through an eye 40 formed on the end wall l8 of the case, which are extends inwardly into the case. The spring 4| is at all positions of the lever 30 tensioned so that the lever 30 is maintained in engagement with the studs 39. The eye 40 and the cross bar 31 are so located that the spring passes over the center of the studs 39 when the lever moves from one extreme position to the other. In its closing position, the lever is situated as shown in Fig. 2, while in its open position, the said lever, is situated as shown in Fig. 3. In either position, the spring 4| tends to hold the lever in such position.
Issuing from the end wall I 8 of case 20 is a tongue 44. This tongue is spaced from the side walls [6 and I! to leave narrow slots 45 therebetween. The said tongue is concentric with the axis of the studs 39. Tongue 44 extends through the opening 35 in lever 30, as likewise does the spring 4|. It will be noted that the two flanges 21 and 28 of the said lever are situated within the slots 45. By means of this construction, the spring 4|, the studs 39 and the interior mechanism of the device is closed by the tongue 44, while the lever is free to swing from one position to the other.
The operation of the invention is as follows: When the closer is in open position, the flanges 27 and 28 of lever 30 engage the upper end of the end wall l8 within the slots 45. This limits the movement produced by the spring 4| and positions the lever 30 so that the trip roller 33 is in the path of movement of the door l4. When the door is swung toward closing position, the door engages this roller and swings the lever 30 in a clockwise direction, causing the said roller to recede within the case 20. As the leverswings, the closing roller 3| is brought into engagement with the door. When the spring 4| passes dead center, the said spring urges the closing lever into closing position, which, likewise, forces the door into 4 its closing position. When the door is opened, the reverse movement of the lever takes place.
The advantages of my invention are manifest. The device is extremely simple in construction and may be manufactured at a nominal cost. Certain of the operating parts are enclosed, whereby the same are protected. The spring is guarded so that injury to the user can not occur. The device is neat and attractive in appearance.
Changes in the specific form of my invention, as herein described, may :be made within the scope of what is claimed without departing from the spirit of my invention.
