HINGE-JOINT.

Specification of Letters Patent.

Patented June 2a, reis.

Application filed March 11, 1914. Serial No. 823,869.

To all whom t may concern Be it known that I,'FRrrz ARTHUR AN- DEnsoN, a subject of the King of Sweden, and a resident of Milton, county of Rock, and State of Wisconsin, have invented certain new and useful Improvements in Hinge- Joints, of which the following is a speciication.

This invention relates to hinge-joints, and more particularly to that class in which the joint comprises a pair of relatively movable hinge members, each having a rollportion one concentric within the other, andwhich does not require a pintle proper.

The main objects of this invention are to provide an improved form ofhinge-joint j rwhich shall be substantially frictionless in operation; which shall be adapted to serve as a dust-tight and light-tight joint; which shall be adapted for being formed mainly from sheet metal; which shall be' convenient to assemble, and which shall be adapted to swing through a broad angular range.

An illustrative -embodiment of this invention isl shown in the accompanying drawings, in which:

Figure 1 is an` end view with the hinge members turned to an angle of 90o from each other. Fig. 2 is a similar view with the hinge members turned into alinement 180D apart. Fig. 3 is a similar view, with the hinge members turned to lie fiat against each other. Fig. 4 is a side elevation with the front of the roll portions of the joint broken away at one end along the line .Al-A of Fig. 2- to show the end thrust bearings,

" lthe screw for the end block being removed.

Fig. 5 is a side view of the leftv hinge member shown in Fig. 4. Fig. 6 is a side view of the right hinge member shown in Fig. 4. Fig-7 1s an axial section of the hinge along the' line B-B of Fig. 2. Fig. 8 is a sectional view similar to Fig. 7 but Lshowing a modification in which thev anti-friction members'are omitted. Fig. 9 is a sectional view similar to Fig. 7 but showing both ends of a long hinge with the middle portion brokenawayj'and illustrating a further modification in which a single unitarystopmember is provided at each end. Fig. 10 isa side view of a long narrow hinge adaptedto eX- tend continuously along the edge of a door lid. or other hinged object. In the 4constructionshown in Figs. l-to 7, the hinge 1 comprises a pair of relatively means 6 are provided comprising a pair of blocks 7 and 8 disposed side by side coaxially Within the rolls and having circular runways 9 in their opposing faces for bearing balls 10 disposed therein. The inner roll 5 (see Fig. 3) A which may be designated as the pintle-roll, is of semicylindrical shape with its free edge or flange 14 turned diametrically inward for coaction against the inner surface of the outer roll 4, which may be designated as the knuckle-roll. The roll 4 is of substantially cylindrical shape and is formed with a medial longitudinal offset 15 opposite from the shank portion 17 of the same hinge member, whereby the part of the roll adjacent to the edge 14 is inwardly set somewhat from thev opposite part and whereby oppositely facing inner and outer shoulders 19 and 20 are provided, which are adapted to serve as stops for the opposite edges 21 and 22 respectively of the pintle roll 5 in opening and closing the hinge. The free edge 25 of the knuckle-roll 1s turned inward medially of its length and provides an end thrust shoulder 28 which serves as a stop for the inner stop block 7, which atl times may have rotative sliding Contact therewith. The edge-flange 14 1s somewhat shorter than the hinge and the inner block 7 is carried rigidly thereby, a slot 30 being provided in said block for receiving an end 31 of the ange 14. The outer block 8 is secured within the knuckle roll by any suitable means as a screw 35. When thus assembled the parts are securely held in place with the bearing balls between the stop members. In the form shown the members2 and 3 have their Shanks 17 and 17 formed flat. It will be understood that the said Shanks may constitute the walls of a box or the like as illustrated in Fig. 10, or may be of any desired form.

. In theconstruction shown in Fig. 8 the stop blocks 46 and 47 are mounted 1n the same way respectively as blocks 7 and 8 and are similar thereto except that no ball-races or balls are provided. For some purposes this form will answer all practical requirements substantiallyA as well as the anti-fric-l tion `form having ball bearings.

'. In the construction shown in Fig. 9 the one at `each end similar to each other and to the blocks 47 shown in Fig. 8, no inner blocks being used. In this instance the ends ofthe inwardly turned flanges 14 and 25 are both adapted at their ends for rotative contact with the blocks 47, and the inwardly turned flange 25 on the knuckle roll may be omitted, its presence not being required as the end blocks 47 and the flange 14 on the pintle roll serve to prevent longitudinal movement. means at both ends is especially desirable where the hinge joint is very long, as in case it is used to provide a continuous hingejoint for extending along the whole length of the edge of a door or lid for rendering the same light and dust tight. Moreover, the end stops impart a neat and finished appearance by closure of the openings at-the ends of the rolls.

Concentric alinement of the rolls throughout their length is maintained by the overlapping of the rolls 4 and 5 and the cooperative action of the flange 14.

The hinge parts may be assembled as follows: The block 7 is placed upon the end of the ange 14. The hinge rolls are then telescoped together and the outer block 8 inserted into the knuckle roll with the bearing balls in place, `and is secured by means of the screw 35.

The operation of the hinge is as follows:

When the members are opened from the closed position shown in Fig. V3 the rolls slide concentrically past each other and the free edge'of the flange 14 slides over the in ner surface of the knuckle roll 4, thereby assisting to hold the pintle roll in place. When the hinge is opened to its full extent,

the shank edge of the pintle roll is arrested by the stop shoulder 20. When the hinge is closed as shown in Fig. 3 the free edge of the pintle roll contacts with the inner shoulder 19 and the shank 17lies against the shank 17.

` Referring to Fig. 4, when the shank 17 is secured to a rigid support as for instance a door frame, and the shank 17 has a load attached thereto, as for instance a door, the vertical load will be carried on the ball bearin s.

gAlthough a preferred specific embodiment of this invention is herein shown together with certain modified forms, it v vlll be .understood that the invention is not l1mited to the precise. construction shown, and that some of the details may be altered or omitted without departing from the spirit of this invention;
