IMPROVEMENT IN SPRING-HINGES,

Specieation forming part'of Letters Patent No. 29,212, dated July 17, 1860; reissue No. 5,932; dated June 23, 1874; application tiled June 1, 1874.

To all whom it may concern:

Beit known that I, AEEAMACKER, of Paterson, in the county of Passaicand State of New Jersey, have invented an Improvement in SpringHinge or Butt, of' which the following is a specification:

The object of my invention is set forth in the claims annexed to this specification.

Figure 1 represents a diametrical section through the eyes of the hinge, showing the parts contained therein and the connection of the spring with the head and foot caps. Fig. 2 is a top view of a complete hinge. Fig. 3 shows the helical spring and the head and foot caps in detail. one of the leaves and eye of the hinge, and that portion to which the head-cap is attached by a peculiar-shaped ring, shown in Fig. 5 in a perspective view.

Similar letters of reference indicate correspondin g parts in all the figures.

This invention is an improvement in that class of hinges commonly called butt-hinges, whereby the leaves of the hinge, and consequently the door, shutter, or gate to which they are applied, are acted upon b y aspring thtt is inclosed within the eyes ofthe hinge, and the spring is capable of being adjusted so as to act with greater or less force upon the leaves, either to keep them open or closed by its recoil. The hinge is so constructed, with a view to j these ojeets, that the adjustments may be ei'- fected with the hinge attached to a door, gate, or shutter with very little labor or loss of' time, and without danger of the displacement ordislocation ot' the parts of the hinge with reference to each other,while, at the same time,the parts can be made durable, and not liable to get deranged under Very hard usage.

Butt-hinges provided with more or less of the 'following parts, viz., eyes somewhat larger than are used on ordinary hinges, having a sleevejoint to keep them in their proper relation, a coiled spring introduced therein, each end of 'which is secured permanently to a cap, and a center rod riveted or otherwise secured at each end and holding all the parts together, were lmou'njnfevioils to the date of my invention. As previously made, they could not, ex-

Fig. 4t is a perspective view of could they be adjusted in any ease by the immediate and sole instrumentality of an adjustable cap, without disturbing the pintle, open ating directly upon the spring and directly attachable to one leaf of the hinge by a detent. In my\ invention a xed cap, provided with a lug projecting into the coil of the spring, interloclrs with the eye of' one leaf of the hinge at the bottom, and into it one end ot' the spring is inserted. At the top I place an adjustable cap, in which one end of the spring takes. It is free to move horizontally, but not vertically, in the act of adjustment, or in a plane parallel to that in which the eyes of the hinge turn- ;while it is detained and held attached tothe spring, and capable of detent attachment to the hinge when adjusted. This cap has holes on its upper sides for the adjusting-lever, a Vwrench-seat or an octagonal or nut form below 'to receive a detentring of corresponding form provided with an arm made V-shaped, to engage a corresponding part of the leaf, and it also hasalug projecting down inside thespring to support it. Arod or pintle passes through both caps and the axis of the spring. It is screwed in to the lower cap, but has an enlarged or conical head seated in the cap, which detains while permitting independent rotary motion of the ripper' cap in a horizontal plane, the pintle itself remaining stationary.

To enable others skilled in the art to fully understand my invention, I will proceed to describe its construction and operation.

In the drawings, A A represent the leaves ot' the hinge, and B B are the eyes of the same, cast quite large in diameter, with male and female portions on their abutting' ends, as shown in Fig. 1, which serve to keep their ends'in their proper place during the movements of the portions A B. The bore of the tubular eyes B B is made of sufficient diameter to admit a strong helical spring, C, the ends of the wire of which are bent out straight and pass into holes in the top and bottom caps or portions D E, respectively, and' connect the spring C with each of these portions D E. The cap D is cast with a short neekand two lugs, a' a, which latter lit into corresj'ionding recesses cast in the bottom of the eye B', and prevents the cap D, and consequently the spring C, from turning at this point. The top portion E is intended to turn, it being furnished only with. a short neck that lits into the end of eye B, for the purpose of keeping it steady and in. place on the eye. ThisY top of the leaf. The spring is attached to the cap E, which is itself attached to the swinging leaf B by the removable ring G. H is the pintle that passes down through the center of eap E, through the helical spring C, and screws into the cap D, and secures the two partsAA together, and the caps D E to the top and bottom of the eyes. J J are lugs that project respectively from the inner ends of the two caps D E a suitable distance into the ends of the spring C, and they serve a very important purpose, in that they give increased stiii'ness to the entire spring by preventing` the ends from collapsing, and by distributing the applied power over its whole length. The use ot' these lugs is, therefore, deemed very important, as it is desirable to have the eyes ef the hinge as small in diameter as possible.

From. this description it will be seen that,`

by removing the ring-piece G or detaehing it from the leafV A, the hinge will move freely, and operate like any ordinary hinge, the bear-4 ing being upon the necks of the caps D E.

Now, by introducing into one of the perfora-` tions in the cylindrical portion of the cap E a pin which will serve for la lever, and turning it round as many times as may be desired, thus winding up the spring C, and, While the spring is held in this state, dropping the ring G on the nut and passingthe1 tenon h into the V- groove, a lock will be formed between the spring and swinging leat1 of thehinge, and the spring may thus be made to act directly on this leaf to close the door, gate,vor shutter to which the hinges may be applied. Then, by raising the ring G from the nut portion and reversing the movement of the cap E, and then dropping the ring iu place again, the spring may be made to operate to keep the ldoor in an open state; or, by disen gaging the V- groove from its tenon, it will be seen that the door will swing open or shut as freely as with the ordinary butt-hinge. The top end ofthe eye B is made to receive a port-ion of the ring G, so that said ring will rest snugly and keep in its proper place when in use. The nut or cap E is Octag- .onal in part, and the inside of the rin g is made to tit this angular portion. Thus, at every eighth turn ot' the cap E the ring may be set in place, giving a gradually-increased force ot' the spring upon the leaf A, and enabling any one to increase or diminish this force at pleas ure, with great facility, and while the hinges are in use, and applied to adoor, gate, or anything else.

I claim as my inventionl. The adjustable cap E, arranged to turn, during adjustment, in a horizontal plane Without vertical movement, and independent of the y pintle, in combination with the spring C.

2. The projecting lugs on the caps D and E, in colnbination with a coiled spring, as and for the purpose set forth.

3. The combination ofthe adjustable cap E, having horizontal Without vertical movement 'in the act of adjustment, and the engaged spring U, with the tubular eyes B B of the hinge-leaves A A', the fixed cap l), the locking-ring G, or any equivalent ddetent devices, and a retaining-Iuntle.
