HINGE CONSTRUCTION Application led November 27, 1928. Serial No. 322,113.

In the design of public and semi-public buildings7 such as churches, it is quite common to provide for heavy outside doors hung on hinges which are supported directly 1n the masonry. In such cases it is customary for one half (known as the pintle) to be set when the building is being erected, although the doors may not be hung until many months afterward. Frequently on such doors ornamental strap hinges are used, which must be placed in an exact predetermined position on the door. Obviously it is impossible to set the pintles in the masonry with such accuracy v that they will all bear equally against their respective hinges, with the result that the door tends to hang unevenly, which makes for excessive wear or diiiiculty of operation. The present invention relates` to a form of pintle primarily intended for use in the field above described but which may be adapted for other similar uses, and which is designed to overcome the foregoing diiiiculties.

This invention may be readily understood by reference to the accompanying drawings which show an illustrative example of the same. In these drawings, Fig. 1 is a sectional View through a hinge in place in a wall; Fig. 2 is a face View thereof, and Fig. 3 is-a section on line 3 3 of Fig. 1.

The pintle bracket 10 here illustrated has two legs provided with serrations to lock in the masonry as shown in Fig. 3. In the front end of the pintle 10 is formed a threaded opening to receive a threaded bushing 12. The top of this bushing is enlarged and is here shown as provided with four apertures or notches 14. A pintle pin 16 has a lower portion 18 of reduced size which fits in the bushing 14, and the lower part of portion 18 is threaded to receive a locknut 20. The hinge proper is here shown as a broad strap hinge 22 formed to fit around the pintle pin 16.

As the masonry is being erected, the pintle brackets 10 alone need be supplied to the masons who will set them in place as accurately as possible. When the time comes to hang the doors, the bushings 14 are screwed down substantially all the way and the pins 16 put in place. The nuts 20 may be screwed on a littlel ways but should not be tightened up. Washers 23 may be slipped over the pins 16, and then the doors are hung and blocked up to their desired position. The bushings 14 are now screwed up until all of them press equally against their respective hinges 22. This may be done by the use of a Spanner wrench, or by inserting a blunt instrument in the openings 14.

It is desirable that the pins 18 should be readily removable, for frequently these heavy doors are taken down in the summer time and therefore the pins 16 should not it too tightly in bushings 14. With a strap hinge such as shown there are severe strains tending to tip the pins 16, thus putting considerable strain on the portion 18 of the pins. According to the present invention this strain is further distributed to the pintle bracket 10 by cut-y ting away the upper portion of the locknut 20 about the pin 18, so that the marginal portions will bear against the pintle bracket 10.

Cutting away this portion of the nut 2O has the further advantage that avrecess is provided into which bushing 14 may be screwed when it is in its bottom position and yet have the full number of threads available for engagement when the bushing is elevated a substantial distance. Tightening up the nutv20 locks the bushing 14 against and at the same time stiffens the pin 16 as has just been described.

It is to be understood that various metals further rotation,

may be used for making the parts described as circumstances may require and that this arrangement may be modiiied for use with other forms of hinges and with other types of pintle setting.

What I claim is: 1. In combination, a pintle bracket having a threaded ho1ea threaded bushing screwed in such hole, a pintle pin having a portion adapted to ft in such bushing and a locknut on the pintle pin adapted to engage with the pintle bracket to hold the pintle pin in place in the bushing and to lock the bushing against undesired turning. Y

2. A combination as speciied in claim l, in

Y Which the threaded portion of the bushing is longer than the thickness of the corresponding threaded portion of the pintle bracket, and the locknut is provided With an opening to receive the endl of the bushing When the saine is screwedall the Way into the pintie' bracket:`f
