HINGE.

Application filed November 18, 1925. Serial No. 89,869.

This invention relates to hinges and more particularly to a hinge, by means of which a shutter or similar closure may be mounted for swinging into and out of a closed position.

One object of the invention is to so form the hinge that when shutters or blinds mounted thereby are swung to an open-position they may be yieldably held in the open position and prevented from being blown shut by wind with the consequent danger of a window glass being broken.

Another object of the invention is to provide one leaf of the hinge with a cylindrical housing for frictional engagement by a spring member carried by the pivot pin which connects the two leaves and turns with the second leaf so that as the leaves are swung toward and away from each other frictional binding between the spring memher and the walls of the housing will yieldably resist movement of the leaves.

Another object of the invention is to prevent snow and ice from accumulating in the housing and preventing movement of the leaves during cold weather.

This invention is illustrated in the accompanying drawing, wherein- Figure 1 is a view showing the improved hinge in elevation with the leaves extending in pposite directions from the pivot pin;

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1;

3 is a vertical sectional view taken on the line 3-3 of Fig. 1, and

Fig. 4 is a fragmentary transverse sectional view taken on the line 44 of Fig. 1.

The hinge forming the subject-matter of this invention includes leaves 1 and 2 formed with openings 3 to receive fasteners by means of which the leaves will be secured, one to a window blind and the other to the 'side of the window frame in the usual manner. While it is stated that the hinge is used to mount a window blind, it will be understood that it may be employed to mount any closure which is to be swung into and out of a closing position. The leaf 1 has its inner end portion 4 reduced in depth to provide an extension which terminates in bearing sleeves 5 and 6 spaced vertically to fit above and below the bearing sleeve 7 at the free end of the tapered inner end portion 8 of the leaf 2. The sleeves 5 and 6 of the leaf 1 are circular in cross section, as shown in Fig. 2, but the sleeve 7 of the leaf 2 is formed with opposed flat sides, as shown in Fig. 4. Therefore, when the pivot pin 9 which conforms in cross section to the contour of the sleeve 7 is inserted, it may turn freely in the sleeves 5 and 6 but will be pre vented from having rotary movement independent of the sleeve 7.

A cylindrical housing 10 is disposed above the reduced inner end portion 4 of the leaf 1 concentric to the sleeve 5 and extends in overhanging relation to the tapered inner end portion 8 of the leaf 2. This housing is preferably formed from an elongated strip integral at one end with the upper end portion of the leaf 1, the strip being bent to assume an annular formation and having its other end anchored to the leaf 1 by being soldered, welded or otherwise firmly secure thereto. When the housing is formed in this manner, it will be understood that the leaves of the hinge are of sheet metal. It is obvious that if desired the two leaves could be formed of cast metal and the housing formed integral with the leaf 1 or as a separate element and suitably secured to the upper end portion of this leaf.

. The upper end portion 11 of the pivot pin 9 extends into the housing or casing 10 and terminates in a flat head 12. The extended upper end portion 11 of the pivot pin is of greater thickness than the portion thereof which fits into the sleeves 5, 6 and 7 and is rectangular in cross section so that it may fit snugly in a similarly shaped opening formed in the hub 13 of the spring member. The hub 13 of the spring member carries arms 14 which extend from the hub, as shown in Fig. 2, and are curved longitudinally so that their free end portions 14' will have contacting engagement with the inner face of the annular wall of the housing. The friction between the arms 14 and the wall of the housing will serve to resist turning of the pivot pin and, therefore, the two leaves of the hinge will be prevented from swinging freely toward and away from each other. A. pin 15 is passed transversely through the hub and enlarged upper end portion of the pivot pin to retain the spring member in proper position.

From an inspection of Fig. 2, it will be readily seen that if the interior of the housing should become filled with ice or snow movement of the arms 14 circumferentially of the housing would be interfered with. It is, therefore, necessary to prevent the accumuill provided if so desired.

lation of snow and ice in the housing and in order to do so there has been provided a cover or cap 16 which fits flat upon the upper edge of the housing, as shown in Fig. 3, and is provided with a depending circumferential flange 17. Arms 18 extend downwardly from the flange 17 at opposite sides of the housing and at their lower free ends are formed with inwardly extending hooks 19 which engage beneath the lower edge of the annular wall of the housing and serve to securely hold the cap or cover in place. While only two arms 18 have been illustrated, it will be obvious that others may be It will also be ob vious that the number of arms let may also be increased.

Having thus described the invention, we claim:

1. A hinge comprising companion leaves having bearing sleeves vertically alined, a pivot pin fitted into, said sleeves and held against rotation relative to one sleeve, a cylindrical housing rigid with one leaf and disposed over said sleeves concentric thereto,

the upper end portion of said pin projecting in to said housing, and a spring member in said housing engaged with the upper end portion of said pin and having a portion in frictional contact with the wall of said housing to yieldably prevent swinging of said leaves.

2. A hinge comprising companion leaves having bearing sleeves vertically alined, a pivot pin fitted into said sleeves and held against rotation relative to one sleeve, a cylindrical housing rigid with one leaf and disposed over said sleeves concentric thereto, the upper end portion of said pin projecting into said housing, a spring member in said housing including a hub fitted upon the upper end portion of said pin and held against rotation thereon, and a resilientarm extending from said hub and having fricgtional contact with the wall of said housing to yieldably prevent swinging of said leaves.

3. A hinge comprising companion leaves having bearing sleeves vertically alined, one having its sleeves non-circular in cross section and the other having its sleeve circular in cross section, a cylindrical housing rigid with one of said leaves and disposed above said sleeves and concentric thereto, a pivot pin fitted in said sleeves and in cross section conforming to the contour of the non-circular sleeve to prevent turning therein, said pin having its upper end projected upwardly into said housing, and a spring member in said housing engaged with the projected upper end portion of said pin and held against turning thereon and having a portion in frictional contact with the inner face of the wall of said housing to yieldably prevent swinging of the leaves towards and away from each other.

i. A hinge comprising companion leaves, one having upperand lower sleeves circular in cross section and the other having a sleeve disposed between the sleeves of the first leaf and non-circular in cross section, a pivot pin extending through said sleeves and .in cross section conforming to the sleeve of the second leaf for turning therewith, a portion of said pin being projected upwardly from the upper sleeve of the first leaf, a cylindrical housing rigid with the first leaf and disposed over its upper sleeve concentric there to, and a spring member held stationary upon the projected upper end portion of said pin and including resilient arms frictionally engaging the walls of said housing to yieldably prevent swinging of said leaves.

5. A hinge comprising companion leaves. one having spaced upper and lower b aring sleeves and. the other having a bearing sleeve fitted between the bearing sleeves of the first leaf, a pivot pin extending through said sleeves to connect said leaves for swinging movement towards and away from each other and having a portion extending above the upper sleeve of the first leaf and terminating in any enlarged head, the sleeves of the first leaf being circular in cross section and the sleeve of the second leaf having opposed fiat sides, the portion of said pin extending through said sleeves conforming in cross section to the sleeve of the second. leaf for turning therewith, a cylindrical housing rigid with the first leaf above the upcr sleeve thereof and concentric to the upper sleeve, and a spring member including a hub portion held stationary upon the enlarged portion of said pin above the upper sleeve of the first leaf, and resilient arms extending from said hub and curved longitudinally and having frictional contacting engagement with the walls of said-housing to eildabl )revent swin in of said leaves] In testimony whereof we affix our signatures.
