i, To all 'whom it may concern:

.useful Improvements in Spring-Hinges, of

which the ollowing is a specification.

This inventionrelates to improvements in .spring hinges.

- the strain thereon is re uce to provi The' objects ofthis'invention are, first, t provide an imlproved spring hinge of the class esi ed to a ow the door to which it is applie to swing in either-direction and automatically close the door. Second, to provvide an improved spring hinge in which the spring is very effectivel sutpported so-that to a minimum and one in which'the s ring is' conveniently adjusted to secure t e desired tension.

`I`liirdto providey an improved spring hinge "which is 'capable of adjust l ment to bring the door into ,proper ositi'on Fourth, to provide-ina spring for' attaching the same to the door and for att/aching tothe floor or' door casing. Fifth,

is comparatively simple and economical in j structure, and at. the same time one in which 'the .wear on the parts is reduced to a mini- Further objects,'and objects-relating to structural details, will definitely appear from the detailed description to follow( I y I accomplish the objects of' my invention by the'devices and means described in the following. specification. i

l The invention is clearly defined and pointed out'in the claims.

A structure embodying the features of my inventionis clearly illustrated in the accompanyingdrawing, 'forming a part of this ,specification, in which,

. The movable member of my improved spring hinge or the member prefera ly at. tached to the door consists of a frame referably made up of a bottom iece 4 en a top piece 5. The forward en of the bottom piece 4 is turned upwardly at 4 and the ends of the top piece 5 are turned downwardly at 5. The end 4 of the bottom plecc and the forward end 5A of the top piece are preferably secured together by means of the screw S.

-The rear downturned end piece 5f is preferably provided with a tongue or tenon projecting into the bottom piece and secured Atherein by means of the screw 7 arranged through the top piece in front of'its down@ ward end. A pair of transverse pieces 6 are provided, the purpose of which will be rought Aout in detail as-the description proceeds. -The frame is preferably securedl to' the door at its lower edge by means of the slotted plate 9, which is secured by suitable screws as 9. The plate 9 is provided with a head of the T-shaped stud 1l on the frame, when presented longitudinally thereto. This stud is arranged through the slot 10 and 'longitudinal slot 10 adapted to receive the when the frame is swung into position it is l securely retained at its forward end. The bottom or base piece of the frame 4 is prefer'- ably provided wit-h an extension 26 through which the screw 27 .is arranged, thus effectively attaching the frame to the door.

A bolt-like reciprocating member 12 having a head 13 at its forward end is slidably supported by the transverse frame pieces In the rear piece 6 is a threaded sleeve 15 in `which the reciprocating member-12 is slidably mounted. O`n the reciprocating meinber is a` collar 14,'between which and the sleevej15 I arrange the coiled spring 16. by lthe adjustment ofthe sleeve 15 the tension of the spring is regulated, thev s ring tending to hold the reciprocating mein er normally forward.

- spring.

The hinge member or floor plate 23 is provided with a cylindrical socket 24 adapted to receive the disk-like cylindrical base'20 on the post 1Q. rThe base 20 is rotatably seatedv .in the socket and is provided with notches 21 in its periphery, which are engaged by the set screws 22, thereby adjustably securing the post in the socket. The post is provided with a head 17, 'provided with a pair of upwardly projecting studs 18, the studs being preferably )rovided with bearing rollers 18/.

The head of the reciprocating member 12 is adapted to bear against the bearing rollers of the head, which are eccentrically arranged relative to the center of the head.or post. The bottom piece of the frame is pivotally mounted on the post between the base and the head thereof, the post being provided with a suitable bearing 25 forthe frame, and the frame also bears on the top of the floor plate, orthe socket portion thereof and on the base of the post. .This effectively su ports the movable portion of the hinge on t e fixed portion. the door is swung, carrying the movable member with it, the head ofthe reciprocating member 12-bearing on the iXed rollers 24 is forced rearwardly, thereby contracting the As soon as the door is released, the spring returns the parts to their normal position. The bearing rollers relieve the parts of friction so thatthe wear is reduced to' a minimum. Also there is no danger ofthe parts catching. When the door is swung to one side until the reciprocating member is thrown beyond the center line, the spring holds the door in its open position.

In applying the hinge or hanging a door, or in the event ofthe parts becoming out of alinement by wear or the' like, the proper adjustment can `be secured by the adjustment of the posti This is accomplishedY through the set screws 22, it only being necessary to loosen one of the set screws and tighten the other to secure the adjustment.v This arrangement is also very convenient in assembling' the part-s, as the post is effectively sel cured bymeans of these set screws. This, in

. connection with the convenient means of the parts in hanging a door.

I have illustrated and describedV my im'- proved spring hinge indetail in the form preferred by me ,on account of structural simplicity. and economy. l am aware, however, that it is ca able of considerable variation in structure7 details without departing from my invention, and I desire to be under-- It will be obvious that-when,
