IMPROVEMENT IN PINTLE OF BUTT-HINGE.

The Schedule referrec'ito in these Letters Patent and making part: of the ,ac-une.

To all whom t may concern:

Be it known that we, LORENZ MAseHAUEu and WiL- LIAM FRANKFURTH, of Milwaukee, inthe county oi' Milwaukee, and State of Wisconsin, have invented a new and useful Improvement in Butt-Hinges; and we do hereby declare that'the ibllowing is a full, clear, and exact description tl1ereof,wl1ich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this speciiieation, in which the drawing represents aview of aVbutt-hinge in an open state, partly' in section, and constructed in accordance with our invention.

Similar letters of reference indicate likeparts.

This invention relates to a new and useful improvement in the construction of the pintle and eyes ofthe leaves of butt-hinges, whereby a door, shutter, or gate may be unhung without unscrewing either leat` of the butts. v

lhe invention consists ina peculiarconstruction of the pintle and eyes ofthe leaves of the butt, whereby the pintle cannot be wholly withdrawn from the butt, and lost or mislaid,.but still drawn out su'liciently far to admit of one leaf of the butt being detached from the other.

A A represent the leaves of a butt-hinge, 011e leaf, A, being provided with two eyes, a, a', at its inner edge, and the other leaf, A', provided with an eye, b, at its inner edge, to lit between the eyes a a', this arrangement being precisely the same as that of an ordinary butt-hinge.

B is the pintle, which passes through the three eyes, a, a, and b. This pintle is formed in a peculiar manner,

its lower end, c, being expanded or made larger in diameter than themain portion, d, the latter being of equal diameter throughout.

The internal diameter of the eye, b, of the leaf A', and the lower eye, a', or" the leaf A, are equal and sufiicientlyvlarge to admit of the enlarged end, c, of the pintle being drawn through them; but the internal diameter of the eye a oi' leaf A is made tapering, the diameter of its.upper part being equal to that of the main part, b, ofthe pintle, and the lower part is recessed out, so that c maybe drawn within a, when the pintle is fully raised, but not allowed to pass through it, the internal chamber of the upper part of a being too small to admit of that.

The pintle is passed through the several eyes from the bottom of the butt upward, and a head, C, is seelued on the upper end of the pintle, to prevent it from dropping out ofthe eyes.

By thisA arrangement, the pintle may be raised, in order to disconnect, the two leaves, A A', ofthe butt, and at the same time the pintle cannot be fully withf drawn from the butt, and consequently cannot be lost or mislaidl Having thus described my invention, l

I claim asA new, and desire to secure by Letters Patent- The pintle B, made of uniform diameter in its middle and upper part, and Aprovided with a tapering expanded lower end, c, in combination with the tapering internal diameter of the upper eye, (l, substantially as v and for the piu'pose set forth.

LORENZ MASCHAUER.
