lUNITED 4,LrS'TAT-'ES PATENT OFFICE WATERPROOF DOOR HINGE VPhilip C. Helz, Milwaukee, Wis.

Application June 17, 1949, Serial No. 99,659

i claim. l

My invention refers to door hinges, especially adapted for use in heavy doors, for refrigerator rooms of packing houses and meat markets, and said hinges may obviously be used on doors of various other commodities.

The primary object of my invention is to provide a simple, durable and adjustable waterproof set of hinges, and the door load is supported upon anti-friction balls, encased in shouldered hollow pintles, and adjusted to take up wear or sag of the door, the hollow pintles being supported in anchor strips secured tothe frame 'wall about said door. The anchorV strips @carry waterproof hollow caps, encasing the'fopen ends of the hollow pintles and also carry lugs', having adjustable bolts therein, engaging the load supporting balls.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combina- I'tion and arrangement of parts, substantially as hereinafter described, and more particularly dened by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed vinvention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 representsl a face View of a hinged door embodying the features of my invention.

Figure 2 is a fragmentary face view of one of the waterproof hinges.

Figure 3 is a longitudinal sectional view of said hinge, the section being indicated by line 3, 3 of Figure 2.

Figure 4 is an enlarged cross section of the hinge and door structure, the section being indicated byline 4, 4 of Figure 1; and

Figure 5 is an enlarged detail horizontal sectional view, taken on the line 5-5 of Figure 2, looking in the direction of the arrows.

Referring by characters to the drawings, A indicates a door frame and B the door seated therein. Secured to the door frame is a longitudinally disposed strap I extending approximately the length of said door.

Secured to the upper and lower portion of the strap I is a pair of hollow caps 2, having anged bases 2', which bases are secured by bolts to the strap I.

Also extending from the strap I is a pair of integral lugs 3, the same being aligned and spaced kfrom the caps 2.

.Each pair of caps and lugs have tted therebetween a hollow hinge pintle barrel 4. The upper end of each pintle is reduced in diameter and shouldered for the reception of a bearing 5, which is interposed between the end portion of the hollow pintle barrel 4 and the waterproof hollow cap 2.

As best indicated in Figure 3 of the drawings, the bore of the hollow pintle barrel 4 is provided with an interior shoulder 4 adjacent to its upper end, which end is provided with an oil channel 6 that extends from the shouldered portion 4' of the pintle barrel to its end.

The strap lug 3 is in threaded engagement with ,a pintle bolt 'I having a reduced portion 'I'I the end of which is concaved to serve as a seat for an antifriction ball 8, which ball is caged between the end of the pintle bolt and the shoulder 4 of the hollow pintle barrel, whereby the door load is sustained.

The reduced portion of the bolt has fitted thereto a roller bearing 5', the same being nested within the hollow pintle barrel.

The Waterproof cap 2 is provided with a centrally disposed oil port 8', which oil port has tted therein a threaded plug 8, whereby said port is closed after the introduction of oil into the hinge, whereby the cap is rendered waterproof and will thus shed all moisture from the hinge assemblage. In order to insure proper alignment of the pair of hinge pintle barrels 4, the same are connected by an offset strap I', which strap is secured to the outer face of the door, as best shown in Figure l of the drawings.

When it is desired to adjust the door against.

sagging in its wall opening, the pintle bolts-f1 are rotated within their lug seats 3 upwardlyu whereby the pintle barrels 4 are raised and their' upper oil port ends will telescopically move within the hollow waterproof caps 2 to thus raise thev door for clearance, due to a load strain that willresult in sagging. It is also understood that the,V

and an adjustable pntle bolt in threaded engagement with the lug and received Within the pintle barrel, a bearing ball mounted between the upper end of the bolt and the interior shoulder of the pintle barrel, said pintle barrel having a reduced upper end received within the cap, a bearing between said reduced upper end and the cap, and a. bearing between the pintle bolt and the pintle barrel.
