DOUBLE-ACTING FLOORHINGE.

`provided with automatic closing means, may

be held aj ar by a draft acting upon one side or the other of the door.

The object of my invention is to provide a closing device consisting of independently acting members operating upon the opposite sides of the door respectively, each of said members being adjustable so that the pressure exerted by either member may be varied to counteract the effect of a draft uponv the door.

With this object in view, the invention consists in the construction and relative arrangement of parts, a preferred embodiment i ofwhich is shown in the accompanying drawings, in which- Figure 1 is a plan view of the device with the cover plate removed, certain portions being in section and other portions broken away to more clearly illustrate the mechanism. Fig. 2 is a sectional view on the line 2 2, Fig. 1, parts of the mechanism being broken away for clear illustration. Fig. 3 is a plan view of one of the pressure levers Fig. 4 is a side elevation of said lever, partly in section. Fig. 5 comprises a plan and side elevation respectively, of a link member used with the pressure levers. Fig. 6 is a side view of a combined pinion and worm gear employed yin the device. Fig. 7 is a perspective view of one of the adjustable pivots and its adjustin rack used with the pressure levers.

In t e embodiment of my invention herein selected for illustration, 1 indicates acasing, which may beV embedded in the Hoor and is provided with a cover plate 2 inclosing the mechanism.

3 is a hinge pintle journaled in the casing having a cover plate with a preferably rec Specication of Letters Patent.

tangular head 4 to lit the usual socketed plate 4 in thebottom of the door.

5 indicates a boss on the cover plate 2, which forms a bearing for the door.

The pintle 3 carries a substantially heartshaped cam 6 engaged by anti-friction rolls 7 carried by the pressure levers 8. As the pressure levers and their operating parts are similar, a description of one will suice for both. The pressure lever 8 is provided with a longitudinal slot or recess 9, more clearly indicated in Fig. 4, which receives the adjustable pivot 10, Fig. 7, with which is connected an adjusting rack 11, the pivot and rack being adapted to slide upon the base of the casing. Engaging the rack is a pinion 12, with which is combined a worm gear 13, said parts being pivoted upon a stud 14 secured to the side of the casing 1. Adjacent the worm gear is mounted a worm 15 having an angular head 16 adapted to receive an adjusting key or wrench. Between the ends of the pressure levers opposite the hinge pintle 3, a powerful spring 17 is mounted upon the stud 18 on the casing, the ends of said spring engaging lugs 19 on the under sides of the pressure levers, said spring tending normally to separate the adjacent ends of the levers and thereby cause the opposite ends to exert pressure upon the heart-shaped cam 6 to restore the same to the normal position shown in Fig. 1 in closing the door. In case the door is held ajar by a draft from one side or the other, the eective action of the pressure lever upon the side upon which the draft comes may be varied by adjusting the position of its pivot 10 by means of the worm 15 and worm gear 13.

As will be seen from an inspection of Fig. 1, unless some preventive means is provided, the action of the cam on the pressure lever 8 will simply tend to push the lever bodily toward the opposite end of the casing, by reason of the position of the slot 9, which receives the pivot 8. To obviate this ditliculty, I provide each pressure lever with a link member consisting of an arm 20 pivoted to the lever at 21 and carrying at its opposite end a stud 22 which is pivoted in the cover plate 2, as indicated at 23, Fig. 2. By this construction, the pressure lever is effectually held against longitudinal movement, whatever the position of its pivot 10 in the slot 9. The length, and connection of the link member 20 with the lever S, are so proportioned that said link member will not interfere with the swinging movement of the pressure lever on its'pivot.

The above described construction provides an effectual double-acting closing means for the door, and at the same time, by reason of the operative independence of the pressure levers, the varying of the effective action of one has no effect upon the action of the other. Vhen the swinging of the door causes the cam to act upon either of the pressure levers, the opposite lever merely presses upon the heart-shaped edge at the inner side of the pintle, so that the position of the inactive pressure lever is not disturbed.

While I have herein described a particular embodiment of my invention, it is to be understood that the same may be altered in detail and relative arrangement of parts without departing from the spirit and scope of the appended claims.

What I claim is:

1. In a double-acting Ycloser for hinges, a hinge pintle, a pair of oppositely and independently acting pressure members, means interposed between said pintle and said pressure members whereby said pressure members may maintain said pintle in normally closed position of the'door, and means for independently varying the effective action of either of said pressure members to counteract unbalanced pressure on the door.

2. In a double-acting closer for a hinge, a hinge pintle, a pair of oppositely and independently acting pressure members, means interposed between said pintle and said members whereby said pint-le may be maintained in normally closed position of the door by said members, means for independently varying the effective action of said pressure members on said pintle to counteract unbalanced pressures on opposite sides of the door, and means for preventing displacement of said pressure members by movement of said pintle.

3. In a double-acting spring hinge, a hinge pintle oppositely acting pressurelevers therefor, means interposed between said pintle and said levers whereby said pintle may be maintained normally in closed position of the door by said members, means for shift-ing the pivots of said levers to vary the operative pressure thereof on said pintle.

4:. In a double-acting spring hinge, a hinge pintle, a pair of oppositely and independently acting pressure levers, a cam on said pintle engaging the ends of said levers adjacent thereto, a spring interposed between the oppo-site ends of said levers, adjustable pivots for said levers and means for manually adjusting said pivots to vary the pressure of said levers-on said pintle.

5. In a doubleacting spring hinge, a hinge pintle, a cam member carried thereby, a pair of oppositely and independently acting spring actuated levers coperating .withV fulcra, a link member for each of said levers having one end pivoted to its lever and the opposite end pivoted at a fixed point to prevent longitudinal movement of said levers.

7. In a doubleacting spring hinge', a hinge pintle, a cam member carried thereby, a pair of oppositely and independently acting spring actuated members, coperating with said cam member, an adjustable fulcrum for each of said levers, a rack engaging each of said fulcra, a combined pinion and worm gear for operating said rack, and a manually operable worm for actuating said worm gear, whereby the effect-ive pressure of said levers respectively may be independently varied.

8. In a double-acting spring hinge, a case 'a hinge pintle, a cam member carried thereby, a pair of o-ppositely and independently acting spring actuated levers, having said cam member between the ends adjacent thereto, a spring located between the opposite ends of said levers, adjustable fulcra for said levers, a linkV member for each of said levers pivoted to the lever intermediate of its length, the opposite end of said link member being pivoted to said case.

9. In a double-acting spring hinge, a casing, a cover plate therefor, a hinge pintle mounted in said casing and having a bearing in the base thereof and in said cover plate, a cam member carried by said pintle, a pair of oppositely and independently acting pressure members mounted in said casing, adjustable pivots for said levers, and means operable from the exterior of said casing for independently adjusting said pivots.

10. In a double-acting spring hinge, a casing, a cover plate therefor, a hinge pintle having a bearing in said casing and cover respectively, a cam member carried bysaid pintle, a pair of oppositely and independently acting spring actuated members cooperating with said cam member, and mounted in said casing, pivots for said members adjusting means for said pivots operable from the exterior of said casing, a link member for each of said levers comprising an arm pivoted to each lever intermediete of its length, said arm being pivoted also at a fixed point upon said casing to prevent longitudinal movement of said lever.

11. In a double-acting closer for hinges, a pintle, a number of oppositely positioned independently acting pressure members, pivots therefor, means interposed between said pintle and one end of each of said pressure members whereby the latter will main Copies of this patent may be obtained for tain said pintle in a normal door closing po- 10 siton, a spring between the other ends of said pressure members, and means for independently varying the pivot point for each of said pressure members.
