To a/ZZ whom it may concern: j

Be it known that I,. HARRY W. STEELE, a citizen of. `the United States, residing at Shelby, Ohio, have'invented certain new and useful Improvements in Spring-Hinges, of which the followin is a specification.

My invention re ates to improvements in double-acting spring-hinges.

One of the objects of my -invention is` to provide a simple and compact form of spring which can be easily applied to a rabbet or recess in the lower corner of the door without detracting from the` appearance or finish thereof. i

vAnother object is to p rovide a spring-hinge which. shall possess all the advantages of a floor-hinge,v (or hinge located in al recess in the floor,) while by its location all danger of moisture getting into the mechanism of the hinge is avoided.

OtherI objects are to simplify the constructionrender it more durable and certain in operation, reduce friction and Wear, and make theparts more readily adjustable to vary the tension on the hinge. y y

With these and' other objects in view the invention includes the. features of construction and yarrangement and combination of arts hereinafter described, and particuarly set forth inthe appended claims.

The invention is illustrated in the accom-v panying drawings, in which- Figure 1 is a sectional. elevation of a portion ofl ak door and its frame, disclosing the hinged construction embodying my invention as applied thereto. Fig. 2 isahoriz'ontal section on line 2 2 of'Fig. 1. Fig.3 is a sectional detail' of certain features of the hinge construction, and Fig. 4 is a detail view inelevation of the adjusting-rin As disclosed in the drawings, the hinge comprises in its construction two members, one of which is fixed and the other movable thereon. The movable member is'secured to the door andy includes the spring-actuat' ing mechanism, while the other or fixed member, which includes the pivotpost, is secured to the floor or door-sill, and it is the movement of the movable member uponthe fixed member which causes the eccentric portions of the head of the post to move the bolt. and increasethe tension on the spring. Referrin by reference characters tothe drawings,t e numeral 1 designates the door,

and 2 the floor, to which is secured a floor- 55 l plate by Which the pivot-post 3 is rigidly carried. The

j ections 4a and an intermediate rounded por.- tion 4b.

(post 3' carries at its upper end ay cross-hea 4, having rounded ears or prov The Operative parts ofthe spring-hinge are llocatedin a rabbet or recess 1iL in the'lower end 5b of the plate 5 in a suitable manner, as 7o l by screw 6b, while its other angular end 6 is detachably connected to the horizontal portion ofthe plate 5, preferably by having a projection 6d seated in a recess 6e in the plate. The sprin and coperating parts are 7 5 located between t ese two members 5 and 6 l vbeing pivoted to allow this.

Which thus constitute a frame therefor, or What I have hereinbefore termed a movable member. v l

Near the outer or swinging` end o fy the 8o frame is located a pivotedplate 7, which may conveniently be supported by havin integral. projections or trunnions 7a seate in recesses 7b in the members 5 and 6, and in an opening '7c in this plate is guided one end of a 85 rodor bolt 8, so as to be freely movable therein in a longitudinal direction, the bolt having a. certain amount` of lateral swinging movement as the door swings and the plate 7 At the oppo- 9o sitel end the boltl is provided withahead 9, which is slidingly supported upon the plate 3at and Whichvhas in its face a centralcurved recess 9b, correspondingto the rounded por, tion 4b ofthe headk of the post, and side re- 95 cesses 9a, corresponding to the roundedprojections 4a of the post-head. An adjustingring 10 is rotatably mounted on the rod or bolt 8 and has a plurality of inclines 10a, each of which is flattened at intervals, asinroo dicated at 10b. The rod or bolt -8 is provided with lateral projections corresponding to these inclines. Square recesses 10c are cut in the oppositeface of the adjusting-ring, and it will be readily seen that by inserting a suit- 105 able instrument having a square end inthese notches the ring may be turned so as to cause t the inclines to act .upon the projections of the bolt or rod, thus forcing the collar outwardly to the pivot, will cause the bolt 8 to be moved outwardly, carrying with it the collar 10 and compressing the spring, thus resisting the tendency of the door to open. The compression on the spring will be increased the further the door is opened until the door has reached a position at right angles to its closed position. A slight further opening movement of the door carries it past the dead-center, so that the spring tends to open it wider, and in order that it may not be opened too wide, but may be held automatically in its open position, I provide shoulders 4c on the head of the post against which the corners on the head of the bolt project, thus limiting the swinging movement of the door. By the use of these rounded projections and corresponding recesses on the post and bolt heads arranged in the manner shown the lateral swinging of the bolt 8 is practically eliminated, and I am therefore enabled to dispense with the use of any link or pitman connection, thereby greatly simplifying the construction, reducing the cost, and making the device more durable. Further, the coacting rounded faces of the bolt and post heads afford bearing-surfaces of sufficient extent to reduce the wear to a minimum, and being packed in grease the friction is almost entirely eliminated.

l find it desirable also to support the door upon a ball-bearing, the balls 12 being located in a raceway formedv in an enlargement at the foot of the pivot-post 4 and in the part 5 of the movable hinge-frame between the plate 13, rigidly secured to the floor and the plate 3a.

In order to provide a neat finish, the sides vof the rabbet are covered by ornamental plates 13a, preferably of the shape shown, which may be conveniently secured in place by set-screws 14, engaging a cross member 15, carried by the upper bar.

Having thus described my invention, what I claim is- 1. A spring-hinge comprising a movable part, a rigid post about which the movable part pivots, a bolt slidably carried by the movable part, said bolt and said post each having a head, one of said heads having a rounded projection on each side of the center and the other head having corresponding recesses and a spring encircling the bolt between relatively fixed and movable abutments, substantially as described.
