specification of Letters Patent.

Patented Oct. 10, 1916.

Application led September 3, 1915. Serial No. 48,759.

To all whom t may concern Be it known that we, ALLEN A. SMITH, a citizen of the United States, and resident of Great Notch, in the county of Passaic and State of New Jersey, and AUGUSTUS A. WEST, a citizen of the United States, and resident of South Ozone Park, county of Queens, State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

The device, the subject of this invention, is a hinge adapted for almost universal use. It has, howe-ver, certain features which make it especially well adapted for use as a door hinge, or as a hinge to be applied upon covers or doors of cabinets that are to be temporarily retained in a semi-opened condition and yet should close positively and firmly when allowed to do so.

This hinge is provided with self operating mechanisms and with a resilient device that will cause the hinge to urge a door or cover into a movement opposed to the opening movement. It is also provided with means for locking the part operated by the resilientk member in a plurality of positions and for retarding the operation of this part and thereby to obtain to a certain degree the effect of a door-check. All of these functions and the construction which makes them possible will be set forthas the specification progresses.

The following is what we consider the best means of carrying out this invention and the accompanying drawings form a part of the complete description, in which- Figure l shows a side elevation of a hinge with the shield removed. Fig. 2 is a front elevation of a complete assembled hinge. Fig. 3 is an elevation of the side opposite to that shown in Fig. 1. Fig. 4 is a central vertical section. Fig. 5 is a side elevation of one-half of the hinge removed. Fig. 6 is a side elevation of the other half of the hinge. Fig. 7 is a perspective. view ofthe movable block. Fig. 8 is a section on the line A-B of Fig. 4. Fig. 9 is a sectional view of a modified construction. Figs. 10, 11 and 12 are fractional views. Fig; l() shows a continuous slot. Fig. 11 a slot having a depression at each end. Fig. 12 a slot having a plurality of depressions and a raised or checking portion. Fig. 13 is an end View of the modification shown in Fig. 9.

Similar reference numerals indicate like parts in all of the figures where they appear.

In general appearance our hinge is not unlike an ordinary hinge but because of the fact that the operating mechanism is contained within the cylinder we may find it necessary or convenient to increase the diameter or even the length of the cylinder. At l and 2 in Fig. 2, we have shown what 1s sometimes called the leaves of a hinge. These leaves are of any size, shape, or design, and may be extended or decorated in any manner desired by the manufacturer. Each of these hinge leaves contains a pluralr4 ity of perforation by means of which the ears are secured in operable posit-ion.

Formed integral with the leaf 1 is a plurality of lugs 3 and 4 formed one adjacent to each end of the leaf. The upper lug 3 is recessed toreceive the end of a tubular member 5 which we pass into and through a perforation in the lower lug. This tubular member must be secured in position and we secure it by screw-threading the lower portion of the perforation in the lower lug and in placing in said screw-threaded portion a screw-threaded plug 6 which will force the member 5 into a firm frictional engagement with the lug 3.

Ity will be noted that we produce a plurality of angular disposed apertures in the tubular member 5. One of these apertures is shown at '7 in Fig. 6 and the other is directly opposite in the same tubular member.

Formed integral with the ear 2 is the cylindrical portion 8 of an external diameter about equal to that of the lugs 3 and 4 and having an internal diameter sufficiently large to allow it to receive and to be partially rotated upon the cylindrical member 5. The cylinder 8 is also provided with a plurality of apertures as indicated at 9 for a purpose that shall appear later.

When the parts are assembled in the relation indicated in Fig. 4, afresilient member or spring is placed within the cylinder 5.100

the hinge is operated, in opening a door, the action of the cylindrical'members 5 and 8 will cause the ends of the pin 12 to be forced upward in the apertures 7 and 9. The block 11 which will be carried upward by the pin 12, will compress the spring 10 and when the door is released the spring 10 will force the block 11 and pin 12 downward with sufficient force to partially rotate one of the cylinders upon the other, the rotation being caused by the movement of the pin 12 in adjacent apertures into which it projects.

Vhen it isdesired that the door remain open, it is forced open against the pressure of the spring until the ends of the pin 12 drop into or are engaged in the depressions 13 and 14 which are provided in the cylindrical members. The door will then remain open until sufficient force is brought to bear to snap the ends of the pin 12 out of the depressions, at which time the door will close by the action of the spring 10.

Ve may provide means for holdingthe door closed. This would be accomplished bv arranging a depression 15 at the lower end of each of the apertures.

We may also provide means for retaining the door at any one of a series of points. This would be accomplished by arranging a plurality of depressions 16, 17 and 18 in each of the apertures or slots.

We have discovered that where our hinge is to be used on very heavy doors it may be desirable to arrange a plurality of springs, such an arrangement as shown in Fig. 9, where the compression spring previously described is shown at 10. In this construction the cylindrical member is made longer and the block 11 does not approach so closely to the bottom of the cylinder 5. Sufficient space is allowed in the cylinder for the reception of an extension spring 19, the upper end 2O of which may be engaged through the block 11 and the lower end of which may be received into the pin 21, which passes through the central perforation in the block G and is retained therein by the nut 22.

lV e desire to call particular attention to the raised portion 28 shown in the slots. This raised portion serves as a means for retarding` the movement of the pin which projects into the slots causing a checking motion very similar kto the action of a door check. This construction is of utmost importance in conjunction with the spring or self closing hinges.

Further modifications may be made within the scope of the appended claims without departing from the principle or sacricing the advantages of the invention.

Having carefully and fully described our invention, vwhat -we claim and desire to secure by Letters Patent is:

1. A hinge having a plurality of cylindrical members each .provided with .an aperture, a block within said cylindrical members and supporting a projection entering said apertures and means for moving said block to obtain a relative motion of said cylindrical members as herein specified.

2. A hinge having a plurality of cylindrical members each provided with an angular disposed aperture, a pin extended into said apertures, a block carried by said pin, and a resilient means for operating said block in one direction to obtain a relative rotation of said cylindrical members as herein specified.

3. A hinge having a plurality of leaves, lugs, formed upon one said leaf, a cylinder formed upon another said leaf and provided with apertures, a second cylinder passing intoand through one said lug and the first said cylinder and secured between said lugs, said second cylinder being provided with apertures, and a movable member within said cylinders and adapted by its movement to produce a relative rotation of said cylinders and leaves as herein specified.

4. A hinge having a plurality of cylindrical members each provided with apertures, leaves operable therewith, a movable member and means for moving it arranged within said cylinders and adapted to rotate said cylinders and means for arresting the movement of said movable member as herein specified.

5. A hinge having va plurality of cylindrical members each provided with a plurality ot' apertures, leaves operable therewith, a movable member within said cylindrical members and adapted to impart a relative movement thereto, a spring for urging said movable member in one direction and means for arresting the force of said spring when said spring is compressed as herein specified.

6. A hinge having cylindrical members, each provided with apertures, a pin movable in said apertures, means for moving said pin and means for retarding the movement of said pin during a portion of its travel.

Signed at the city of New York, county and State of New York, this 26th day of August 1915, in the presence of two wit* nesses.
