DOOR-CLOSER.

Specification of Letters Patent. I Pate nt ed Oct. 30,1917.

Application filed March 21, 1916. Serial N 'o. 85,583.

To (ZZZ whom it may concern:

Be it known that I, ALBERT T. 'LOFTSGA AR DEN, citizen of the United States, residing at Powell, in the county of Park and State of Wyoming, have invented certain new and useful Improvements in Door-Closers, of which the following is a specification.

My present invention has to do" with sprang-actuated door-closing devices; and.

generic combination and specific" embodiments hereinafter described and definitely;

pointed out in the claims appended.

In the accompanying drawings which are hereby made a part hereof:

Figure 1 is a perspective of the preferred form of my invention.

Fig. 2 is a horizontal section through the door and door casing and showing the improved device in plan.

Fig. 3 is a transverse section taken on the line 33 of Fig. 2 and showing the pivotal connection between the swinging arms of the device.

Referring by numeral to the drawings:

1 is the side stile of a door frame, and 2, a door, hinged to the stile in the ordinary or any other suitable manner, as shown in Fig. 1.

In furtherance of my invention thestile 1 and door 2 are provided on their faces with brackets 4.

To the stile bracket 4 is hinged one end of the arcuate, horizontally-swinging arm 5.

The said arm 5 is provided adjacent to its middle with a loop-shaped outwardly-extending portion 6, and its free end 5" is arranged comparatively near the outer side or face of the door 2 as best shown in Fig. 2; the said free end being preferably provided with an upstanding apertured lug 7.

The bracket 4 on the face of the door 2 serves for the pivotal connection of a second horizontally-swinging arm 8. This arm 8 is also of general arcuate form, and is arranged with its free end 8 adjacent to'the tion of the arms each to the other.

face of the door- Near its middle the 8 is provided with an outwardly extending loop 9 which straddles theportion f the door arm 5 and is pivotally'connected thereto, preferably through the medium of a pintle 10 which enables each arm to swing onthe other; It willbe apparent that this arrangement disposes the I arm portions. 8" I and: 9 at the same sideof thedoor closer considered as a whole which is. desirable inasmuch as it promotes free working of the sprmg that will now be described; Itawill also be. apparent that the free end of the armportion 8" is" shaped as ahook, Fig. ,1, this'rbeing materially advantageous inasmuch as the spring: can be readily unhooked, thereby allowing the doorto be left open when desired;

Interposed between the free ends of the swinging arms 5 and Sand connected therewith is a retractile spring 11 equipped with means 12 for regulating the tension thereof. In the preferred arrangement, the spring 11 at one end is connected directly to the end 8 of the arm 8, and the opposite end of the spring is coiled back of a nut 13 which in combination with a bolt 14 forms the tension-regulating means for the spring.

The said bolt 14 extends through the aperture of the lug 7 and has a kerfed head back of said lug, and hence it will be understood that turning of the bolt will be attended by tightening or loosening of the spring according to the direction in which the bolt is turned.

Manifestly on opening of the door 2, the

free ends of the arms 5 and 8 will be moved away from each other, and the spring will be stretched or put under tension. Consequently when the'door is released and. the 9 spring contracts to its normal state, the spring will operate through the arms 5 and 8 to close the door, and this promptly and powerfully becauseof the considerable leverage the spring is enabled to exert.

It will be appreciated from the foregoing that the embodiment thus far specifically described is simple and strong, and is well adapted .to' withstand shocks and rough usage as well as exposure to the weather. I would also direct attention to the fact that in said embodiment the retractile spring is connected to the portion of one swinging arm that extends beyond the pivotal connechaving a free end disposed adjacent to the face of the door and also having an outwardly-extending loop-shaped portion adjaeentito its middle, an arcuate, horizontallyswinging armpivoted to the door bracket and having .a :free end adjacent to the face of thepdoiors and also having an outwardly extending loop straddling and pivotally con- ;nected'. to the outwardly-extending loop shapedportion of the firstnamed arm, and :a retractile: springextending between and 20 connectedwith'vthe free ends'of said arms. ,IniaLdoor-closmg device, the combinationof a door-frame, a doorlnnged thereto,

an arcuate, horizontally. swinging arm pivotan connected at one endw-ith theface'of the frame and having .afree endidispos ed 'adjace nt'to theface of the door, an. arcuate, horizontally swlnging arm pivotally connected with the face of the door and pivot- .I In testimony whereof I '111 presence-of two witnesses.

ally connected at an intermediate point of its length with the intermediate portion of the first-named arm and having a free end adjacent to the face of-the door, and a retractile spring extending between and connected with the free ends of said arms and inclosed between the arms and the face of the door in approximate parallel relation to the latter. I

A spring-actuated door closing device, comprising arms pivotally connected together adjacent .to theirmiddles, means at oneend of one arm for attaching thesame to a (lOOlf IfliLHlfi, means at one end of the and-the-face ofthe doorin approximate parallel relation to the latter.
