PatentedvrMay 5, 19131 Y forro s'rnrs Aralar FFicrEf ARTHUR M. FERRIN, OF RED ROCK, MONTANA Y' DOOR OR GATE CLOSER Appneation med september 11, 192e. serial No. 391,866.y

The present invention relates to door or gate closers and the primary yobject of the invention is to provide an improved door `closer of such construction as to remain operative for an indefinite period of time.

A further,v object of the'iiivention is to provide a door closer permitting of the door be? ing easily opened against tension of they closer and yet insuring closing of the door.

A further objectof'this invention is to providea door closer embodying a construction whereby the spring is only distended for a short distance and thus allowing the spring` rto retain its tension for an indefinite period of time.

provide an improved door closer of simple y construction, and one which will insure clos-r ing of .the door when swung to its fully opened position.

O ther objects and advantages oit the invention will be apparent during the course of the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification and in which drawings, y y

Figure 1 is a view looking at the inner side of a screen door equipped with the improved closer.

`Figure 2is a View showing the door in the fully open position.

Figure 3 is anenlarged horizontal section taken through the door casing and clearly illustrating the manner in which the closer is applied. l Figure 4 is a view showing a slightly modified formof closer.

Figure 5 is a view showing the door in its fully open'position, the door being provided with the form of closer shown in Figure 4.

Figure 6 is a ragme'ntary'horizontal section through the door casing and showing the form of closer illustrated in Figures 4 and 5.

above orfbelow the' staple15.

Referring to the drawings in details, and wherein similar reference characters designate corresponding parts throughout the several views, and with particular reference to Figures 1, 2 and 3, the letter A designates a door casing, B a'screen door hingedfto the casing A and C a closer for the door B.

The door B vmaybe of any construction kand inthe example shown includes'hingeand 'Avlatchjpstiles5 and respectively and a rail7. The doorB may be hinged by the stile 5 to the jamb kSof the casing A.

'Referring now to the speciiic construction of the jcloser C, the saine comprises a coil spring 10 having a hook provided at each end thereof, the hook at one end of the `spring being connected in the eye of a screw eye 11 threaded into the vrail 7, adjacent the' latch stile 6. Connected in the eyeatv the opposite end of the coil spring 10is a pulleyincluding ayoke 12 infwhich is mounted a sheave 13.

ber v14V which may consist of a cord',` chain or cable, one end 'of which is attached as by means of a stapleV 15'to the hinge stile 5. tached to the opposite end of the flexible meniber 14 is a leaf spring or flat spring strip 16 `having apertured ends, one end of whichis lintended. to carry ascreweye 17 for attachment'to the jamb 8 k'at an elevation slightly Thei'lat spring strip is cfa length greater thanthe width of the hinge stile 5 and veX- tends with one latiface confronting the inner surface ofthe'hinge stile. The ystrip y16 is` secured by the eye`17 in spaced relation from the stile 5 'and atan elevation on the jamb 8 Trained about the sheave 13 is a Vflexible inein- A below the staple 15 so-that when the door is Y y swung open theistrip 16will engage the hinge vstile below the staple 15. By observing Figure 3 it willbe seen that the tension of theV coil spring 10 will norniallyhold the door closed.

1Nhen the door B is swungto the position fas shown'in Figure 2, the coil spring 10v is dist-ended and the flat spring strip 16 is sprung about the corner edge of the hinge stile. The tendency of the spring strip to returnv to a straight Vposition will exert a lateral pull on the cord 14 away from the rail full open lil Which the closer is applied.'`

7 and impart -initial movement to the door, after which the coil spring 10 Will act to fully close the door. It Will be observed that the spring l0 is not bent around the edge of the hinge stile when the door is open, but is distended in a straight line along the rail 7. The Hat stripl engaging the hinge stile will have no tendency to mar the stile as in the case Wherethe coil springs are connected between the door and door casing jamb. Owing to the pulley being Vconnected.. to one end of the coil spring, the spring Will only be stretched for a very short distance and thus the spring will retain its tension for an indeiinite period of time. A

The tension of the coil spring 10 may be variedthrough lengthening thei'lexible cord Vor cable 14, and this simple means will permit of the closer being readily appliedto doors of Vvarious Widths. While 'the coilspring has been shown attached to the rail 7 it `Will readily be apparent the eye 11 may beV connected at any location alongvthe latch stileV 6. The closer may also be connected diagonallyacross the door iffso desired, so-that the closer Will also act Vas means for preventing sagging of the door.

Y In Figures 4, and 6 a closer has been shown Where a quicker closing ofthe .door is desired, and with this form of closer the flexible cord or cable 14 and the pulley are removed and one end ofthe fiat spring strip connected directly to' one end of. the coil Without departing from the spirit of the invention or the scope of the claims.

I claim:

l. The combination with a door and its casing, of a coil spring having one end attached to the door adjacent the free edge of the door, a sheave carried-by the free end of the spring, and a flexible pull cord trained over the sheave With one end attached to the door and having its opposite end connected with a .ja'mb .piece of said casing.

2. In a door closer the combination With a door including a hinge stile, and a casing for the door.. including a jamb piece, of a coil spring attached at' one end to the door adjacent the free edge of the door, va .pulley carried by the free end of the spring, a pull cord trained over the pulleyA and having one end attached to the hinge stile, a Hat spring strip connected at one end to the free end of the pull cord and extendingacross the hinge stile, and means connecting the opposite end of the strip to said jamb at a location below the point of attachment of .the pullcord to the hinge stile.

spring. In Figures 4, 5- and l6, 10 designates the coil spring connected" at one end to `the rail 7 and having the hook at its oppositeend connected With one end of the leaf spring. or flat spring strip 16', the opposite end ofthe strip being connected lby the screw eye 17 to the amb 8. Vith thisffoiin ofcloser the coil spring Will be distended for av greater length than thatof the spring shown in Figures l, 2 and 3, but Will be distendediin a straight line along the rail 7. The'strip -16 Will be sprung around the edge of the stile 5 and the normal tendency of the Y strip Yto straightenaoutwill impart initialclosing to the door.' l

In both illustrations of the invention it Will rb'e'lseenthat the springs arel distended in a straight line and that the spring strips are sprung `about the hinge stiler ofthe d'oorfor .initial closingnmovement of the door., Y

Froin'the foregoing-it- Ywill bejapparent that a novel and improved construction or-closers of this kind has been an operative condition for a long period of time. It Will ialsobe apparent that a `novel construction Yhas'been* disclosed permitting attachment to variousssizes of doors, and aconstruction Whichwill not marthe door to Changes-,in detail may be made to theiforms ot.- invention herein shown and described,

providedl which vwill be 'eliicient in Voperation and remain in iio
