Letters Patent No. 103,859, dated Ju e 7, 1370.
IMPROVEMENT m noon-enemas.
The Schedule referred to in these Letters Patent and making part of the same- I, JOHN T. Fo wnLL, of Camden, in the county of Camden and State of New Jersey, have invented certain Improvements in Door-Hinges, of which the following is a specification. Y
The nature of my invention consists in a hinge,
provided with double inclined ways, upon which the lower end of a vertical rod traverses back and forth, to admit of the door swinging either way, within the range of a half circle, the said rod being forced down by means of a spring as it traverses the inclined planes. The hinge and'the inclined planes are connected, and the doorconsequently preserves anniform height as it is caused to swing around.
To enable others skilled iii the art to which my improvement appertains, to make and use my invention, I will now give a detailed description thereof.
g In the accompanying drawing, which makes a pair of this specification- Figure 1 is a face viewof a door, A, hung in the frame B, with the improved hinges.
Figure 2 is a cross-section at the line a: roof-fig. 1.
Like letters'in all the figures indicate the same parts.
A is a door, and
B, a'frame, in which it is hung.
O O are hinges, constructed on the improved plan.
The hinges have double inclined ways a at their lower ends, upon which the lower ends of the rod 71 in the sockets d are pressed by. the wire springs c, to incline the door to its position in .the frame, the spring permitting the rods to rise on the inclined planes as the door is swuiig open either way.
The stationary part f of the hinge, and the double inclined ways a, are in a single piece, and hence thedoor, as it is swung open, remains at the same height as when closed.
Ordinarily, when double inclined ways are used to bring a door or gate back to its closed position, the hinge is separate from the said ways, and conse-,
quently the door changes its altitudinal position'as a projecting device from its lower edge traverses the inclined ways; hence will be seen the advantage resulting from the use of the improved hinge, whereby the door or gate remains at aregular height, and consequently requires less force to open it.
The hinge is also susceptible of being made in the usual manner, except the additional part-s necessary in completing the improvement.
The fly part f is represented with double flanges, seen clearly in fig. 2, which are sunk into the'dcor-A, and confined by means of screws.
I do not confine myself to this mode, as other forms of construction might be used and answer the \Vhat I claim as new, and desire to secure by Letters Patent, is-
The combination and arrangement of the double inclined ways a ,-with the stationary part f of the hinge O, and the spring rod 1), with the-fly part f, substantially in the manner and for the purpose set forth. 7
In testimony that the above is my invention, 1 have hereunto set my hand and aflixed my seal this 26th day of March, 1870. r
