PINTLE-HINGE.

' Specification of Letters Patent.

Patented Dec. 2, 1919;

Application led October 24, 1917. Serial N o. 198,289.

T 0 all whom it may concern.'

Be it known that I, DONALD E. WILLARD, a citizen of the United States, residing at Decatur, in the county of Macon and State of illinois, have invented certain new and useful Improvements in Pintle-Hinges, of which the following is a specification.

My invention refers to hinges particularly to the type of hinge for use in swinging lirel doors and the like. Y

In installing swinging fire doors in masonry walls it has been customary to provide hinges 'extendingbeyond the f ace of the wall with which straps attached to the doors cooperate, the wall member being generally provided with a pin and the 'strap member with aneye for fitting over said pin, the wall memberbeing bolted in the wall. It will be understood that swinging fire doors for* the most part remain inV open lposition that is,- swung backagainst `the wall leaving the passageway freevand are closed only at night in some instances, or only when a fire occurs in the building which closing 1s brought about usually by automatic means. `When a door of the character described is allowed to remain in open position for some time, sagging occurs which sagging does no harm as long as the door is open but which prevents proper closing of the door when moved into the door opening, thus defeating one of the purposes of such doors in not making a tight closure. Various means have been devised to Overcome sagging but without success. ,U

The obJect of my Invention 1s to provide a novel means for supporting a swinging fire door so that sagging is prevented.

A still further object is to provide a novel pintle hinge for mounting swinging re doors so that the line of thrust against one pintle will be counterbalanced by the line of thrust against the other and thus movement of the pintles prevented.

These and other objects will be apparent from the drawings, wherein- Figure 1 represents an elevation of a swinging re door mounted on a brick wall, the door being in closed position, the doorway being indicated indotted lines.-

Fig. 2 is an enlarged view of the preferred embodiment of my invention. Y

Fig. 3 is a sectional view Online 3 3 of Fig. 2 and straps 8 and 9 engage.

Fig. 4; is a top plan view of the preferred form of my invention.

5 represents the usual brick wall having therein the doorway 6 forming a passageway through the wall. Y

provided this being of the usual well known construction made of metal Yadapted to prevent the passage of Vire thereby. lFirmly bolted to the door are upper and lower straps 8 and 9 forming portions of the hinges and having at their outer ends eyesv 10. IThe bracket orwall member which I V11 to a point slightly above the upper por' tion of the horizontal arm 12.` Mounted within the aperture 13 lat the outer end of member 12 is a pin 16 having a reduced por# tion 17 for entering said aperture 13, shoulder, 18 being formed at the upper portion u For closing said doorway in case of ire, `the fire door 7 1sYV ofthe reduced part 17 forming a bearing against the upper surface of the member 12. It is with the pin16 that the eyes 10 of the wall member to the wall, I prefer to employ a single bolt 19, over the head of which the slotted portion 15 of the bracket is slid with the hood embracing said head, the length of the slot 15 being` such as to position the wall flange 11 on the bolt so that the axis of the For attaching the bolt is coincident with the point where the pin 16 delivers to the bracket a turning thrust caused by the straps 8 and 9 thus bringing the turning thrust in actual alinement with this bolt, the result of which is that when such thrust is brought against the bracket no turning whatsoever will result as to the bolt' is so positioned with respect to the application of the turning thrust as to prevent any bodily displacement ofthe wall flange 11 through action on the pintle 16.

It will now be observed that the thrustto the left caused by the upper strap 8 and the thrust to the right caused by the lower strap 9 will be directly in line with the centers of the bolts, hence, nol turning of the p wall brackets will occur as the thrust is directly to the axes of the bolts. Swinging of the wall brackets about the bolts as centers is eliminated and consequently no sagging of the door occurs so that a perfect closing is made when the door is swung against the opening 6. If desired, two swinging doors may be mounted on each side of thc wall 5 in which lcase the bolts 19 would be long enough to fasten the oppositely disposed brackets to the wall. Y

Such modifications as are permissible in a device of the class described I consideras coming within the scope of my invention.

I claim :V

l. A hinge comprising in combination a wall member and a door member, the wall member having a plate of relatively substantial size, a projection therefrom adapted to support the doorv member, a bolt extending through the plate at the center thereof, and arranged to lie in the line of thrust of the turning force applied to said door member whereby the turning of said plate is prevented.

2. In a hinge of the class described a door member and a wall member, the combination oic a wall flange of relatively great area, a cover member integral with said wall flange adapted to receive a bolt, said wall ange being provided with a slot extending from the lower edge thereof to substantially mid position of said cover, a horizontally extending member projecting from said wall flange and vprovided at its outer end with a pin receiving aperture, the parts being arranged with the axis oi2 the bolt in substantial alinement with the line of thrust imparted to said pin by said door whereby said thrust is transmitted to lhe said wall ange at the axial line of said olt.

3. A hinge including in combination, a door member, and a wall member, the wall member having a vertically disposed wall plate with a slot extending from the lower edge upwardly, a hood overlying said slot, the parts being arranged to embrace the end of theV bolt, an arm extending outwardly of said plate and hood with an enlarged end portion, a plintle secured to said end portion for coperating with the door portion, .the whole being arranged so that the axis of the bolt includes thev center of turning movement imparted to said wall member by the door.

4. A hinge in combination with a door,

of a headed bolt secured in the wall, the hinge having a wall memberV with a vertically disposed slotted wall plate Jfor retention by said bolt, the wall member also having a hood for embracingthe head of the bolt, an arm extending outwardly from said plate and hood and having an apertured horizontally disposed end forming a bearing surface, a pintle secured'in said aperture, the length of the slot in the plate being such that the wall'member is retained in position on the wall with the axis of the bolt passing through lthe center of retative movement of the wall member which movement is iniparted to said pintle by the door, whereby relative movement of said wall member is prevented.

Signed at Danville, State of Illinois, this 16th day of October, A. D. 1917.
