WILLIAM LOVETTE, OF MARINER HARBOR, NEW YORK.
SPECIFICATION forming part of Letters Patent N0. 770,595, dated September 20, 1904.
Application filed March 5, 1904- Serial No. 196,753. (No model.)
T0 all whom it muy concern.:
Be it known that I, WILLIAM LOVETTE, a citizen of the United States, residing at Mariner Harbor, county of Richmond, and State of New York, have invented a certain new and useful Improvement in Hinges, of which the following is a specification.
My invention relates to a new and useful irnprovernent in hinges, and has for its object to provide a hinge in which the pintle of the hinge may be solid with one leaf of the same and the two parts of the hinge may be placed together by the simple insertion of the pintle horizontally into the bearings.
With these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, `the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure l is an elevation of the top and bottom hinges of a door, the two leaves of the hinge being separated and the door being shown in position at right angles to the doorjanib; Fig. 2, a section taken on the line 2 2 of Fig. l, the two parts of the hinge being together and in a position to be separated; Fig. 3, a section taken on the line 3 3 of Fig. l, the two parts of the hinge being together and in position to be separated.
A represents the upper hinge, and B the lower hinge, of a door.
O represents the leaf of the upper hinge secured to the door, and D the leaf of the upper hinge secured to the door-jamb.
E represents the leaf of the lower hinge secured to the door, and F represents the leaf of the lower hinge secured to the door-jamb, as will be seen in Fig. l. The pintle of the hinge is formed with the leaf O of the upper hinge secured to the door, and the pintle of the lower hinge is formed with the leaf F secured to the door-jamb. The leaves O and F of the upper and lower hinges, respectively, have formed upon their outer ends the cylindrical portions G, which cylindrical portions are cut away at the points G', and across these cut-awayportions extend the pintles H, formed integral with the hinge. Each of these sections of pintles within the cut-away portions G are formed cylindrical throughout a portion or portions of their lengths, the balance of the pintles being iiattened, as represented at I. The leaves D and E of the upper and lower hinges, respectively, have secured to them the bearings J, said bearings being formed with a vertical bore the same diameter as the cylindrical part of the pintles H. Each of the bearings J is cut away or slotted from the central bore outward, as represented at J, to allow the cylindrical and fiattened portion of the pintles H to enter within the bearings; but that portion of the slot in the bearings through which the flattened portion I of the pintles pass is of such a width that the flattened portion of the pintles can only pass through the slot edgewise. Therefore after the pintles have passed within the bearings they can only be removed from said bearings by bringing the flattened portion of the pintles in exact alinement with the slots J of the bearings. Therefore in order to hang a door it is only necessary to hold the door in such a position that the flattened portions of the pintles will pass through the slots J' into the bearings, and then by forcing the pintles into the bearings the door is hung.
As will be seen by Fig. l, the pintles are secured to that leaf of the hinge fastened to the door in the upper hinge and formed with that leaf of the hinge secured to the door-jamb of the lower hinge. Therefore in order to remove the door from its hinges the door must be moved in the direction of the arrow No. lin Fig. 2 of the upper hinge and in the opposite direction or in the direction of the arrow No. 1 in Fig. 3 of the lower hinge, and there will be no danger of the door being accidentally removed from its hinges even though the door should stand ajar with the flattened portion of the pintles in proper' alinement with the slots, for the tendency always of a properly-hung door is for the upper portion of the door to tend to fall in the direction of arrow No. 2 in Fig. 2 at the up- IOO per hinge, and the tendency of the lower end of the door is to move in the direction of the arrow No. 2 in Fig. 3. Therefore as the direction of these tendencies of movement upon the part of the door is directly opposite to the direction in which the door shall be moved to remove it from its hinges it would not be possible for the door to be accidentally removed from its hinges in the ordinary opening and closing of the door.
Of course I do not wish to be limited to the eXact construction here shown, as slight modifications could be made without departing from the spirit of my invention.
Having ythus fully described my invention, what I claim as new and useful is- In door-hinges, the combination with a door and its jamb, of an upper hinge comprisingv in its construction two leaves, the pintle of the hinge being formed integral with the leaf secured to the door, bearings formed with the other leaf, and a lower hinge comprising in its construction two leaves, the pintle of this hinge being formed integral with the leaf secured to the door-jamb, bearings formed with y the -other leaf secured to the door, a portion of each ofthe pintles being formed cylindrical and a portion flattened, each of the bearing being provided with acentral bore of a diam- In testimony whereof I have hereunto affixed my signature in the presence of two subscrIbIng witnesses.
