IMPROVEMENT IN. BUTT-HINGES.

Spcci'lcatiou'forming part of Letters Patent No..36,883, dated November 4, 1862; Reissue N0. I,3-96, dated 'l February 3, 1863.

.To all whom it may concern: Y l

Be it known that JOHN F. TOWNSENI'), of West-field, in the countyof Chautauqua and State of New York, did invent certain new and useful Improvements in Right and Left Butt-H in ges, forwhich Letters Patent of the United States were granted himself and PAS- OAL P. PRATT, of Bualo, New' York, on the 4th dayof November 1862; and we do hereby declare that the ollowing is a full and exact description thereof', reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a perspective view of our improved hinge, with its two parts separated; Fig. 2, a view of the same as applied to alefthand door,la portion of the door and jamb being show in elevation; Fig, 3, a similar view showing the hinge as applied to a right-hand door; Fig. 4, a horizontal cross-section of the base. or jamb portion of the hinge through one of the screw-holes.

Like I etters ofrcference indicate corresponding parts in all the ligures.

Ordinary loose-jointed butt-hinges are made up of two parts-a base or supporting portion secured rigidly to the jamb, and a movable portio11,connectcd with it, secured to the door. The former consist of a knuckle or round supporting a pin or axis, and provided with a leaf by which it is secured to the wood, and the latter of a -socket fitting over the pin of the jamb-piece and a leaf vof similar shape. In both parts the leaf projects tangentially from the knuckle orsocket; or, in other words the latter is situated laterally or on one side of the plane of the leaf, so that when the two parts are united they will fold together in contact without diiculty. It is manifest that a hinge constructed in this way can be used on only one side ot'v a door, for if removed to the other side the knuckle of the base orjambi portion willproject on the wron g side of the theright side the pin or axis will be inverted.-

Our invention consists, rst, in ladapting the base or jamb piece to use on either side of the. door, by a peculiar construction, hereinafter dcscribed; and, secondly, in the use, in connection therewith, of a movable piece, -which is Y,adapted to use on either side by being inverted, thereby producing a reversible or right and left hand hinge. l

To accomplish the result desired, the base or jamb piece A, Fig. 1`, has a knuckle or round,

e, of the usual size and shape, and extending upward a suitable height-say about half the lheight of the hinge, more or less-and to this knuckle is secured thepin or axis f, which forms the bearing of the hinge in the usual manner. The leaf. h, instead of projecting tangentially, or from one side of the knuckle, as in the coinmon device, projects radially or centrally, as clearly represented, reception of the screws, insteadof being countersunk on only one side, as ordinarily dono,

are countersunk on both sides, as indicated most clearly in Fig. 4. This portion of thehinge thus formed is perfectly adaptable to use on either the right or left handy side, es `will presently be described.

The movable portion B of the hinge, or that rportion which is secured to the door, issubstantially of the shape represented at the top in Fig. 1, and does not diii'er very essentially from the corresponding piece of the ordinary hinge-that is, it has the ordinary socket,.g, of suitable size and height, from which projects tangentially, or from one side, the ordinary leaf, k, and its screw-holes are countersunk on only one side.. We prefer to make of the hinge longer the leaf of this portion than that of the other, but proportionably lighter, as it admits of more screws and of placing them farther apart,'so that a stronger fastening is obtained, and the door'is less liable to sag or work` loose on the hinges. This, hwever, is not absolutely required, ard this leaf may, if desired, be made of equal size as' or even smaller than the other, the relative size and proportion not a'ecting the principle of its construction. .'Ihus arranged, there is no diiculty` in applying the hinge for right or left hand use. applied on the left, and in Fg.,3 on the right, the jai'nb being indicated by y of the door by C. To change from one to the other, itis only necessary to reverse the basepiece A, or place it the other side out, the change making no dilerence with the relative` and the holes iifor the 1n Fig.. 2. it is represented as D, and the edge perfect right and left hinge.

2 V l .A Lese position of its knuckle and pin, which are in al radial line with the leaf, and'then invert the movable piece B, so as to change the position of its leaf relatively to that of A. Thus, by making the basepieee .A with its leaf pro- Y jecting on a central plane, and countersinking its screw-holes on both sides, so as to be placed either side out, itis perfectly adapted to the purpose desired, and can beused'with the or dinary tangential socket-piece, B, to form a of this special construction of the base-piece Aare apparent-without it the perfect device cannot be produced.

This hinge thus produced is as simple, cheap, and effective as othe ordinary butt-hinge, with the additional advantage of its twofold` use. Itis put together in the same manner, and is as little limited in the extent of its turning motion. projecting ont laterally from the plane ofthe leaf, allows the door to close and iit closely in its seat in the frame, the two parts of the hinge being sunk ush into the wood-work, as

usual, and thus presenting a neat appearance.

We are aware that screw-holes countersunk on both sides have before been employed in The advantages The socket of the movable piece, by

other relations, but such we do not claim sepa` l rately; but A 4 v.

What we claim as the invention of the said J oHN F. ToWNsENn is-` 1. The base or sustaining portion A of the hinge, consisting of the leaf h, projecting-radially or centrally from the knuckle e and pin f, and having-screw holes i1 eountersunk on veach side thereof, the whole arranged and operating substantially as described, and for the purpose herein set forth.

2. In combination with the base-piece A' thus formed, the, movablek piece B,l with its leaf projecting tangentially from the 'socket in such a manner that by inverti-ng it it is adapted to right/and left use, as herein specified.

In witness whereof we have lhereunto set our'hands this 8th day of December, 1862.:
