Letters Patent No. 110,020, dated December 13, 1870.
IMPROVEMENT iN' HINGES.
' The Schedule referred to in these Letters Patent and making part of thevvsame.
I, RUDOLF DRAHOTA, of Philadelphia, county `of 'Ihiladelphizg State of Pennsylvaniayhave linvented an Improvement in Hinges, of 'which the following is a specication.`
Nature and Object of the Intention.. My invention relates to an improvement in vwhat vare known as spiral hinges, and
-of which are openings for the passage of screws, by
which it may be secured in the usual manner, to a door or other object.
At the edge of one leaf are two lugs or projections, c c, recessed for the reception of the ends of a pin or rod, b, on whiclrisa spiral projection, a, adapted to a hollow spiral projection, a', on the edge of the opposite leaf.
The pin b is screwed into the hollow spiral projection a', and its ends4 are then introduced into the recessed lugs c c, and are there secured by solder or otherwise; the two leaves of the-hinge being thus connected together.
If the leaf A is secured to a. door-frame, and the leaf A' to the door, lthe hinge, on the door being opened, will assume the position shown in Iig. 1, so that, when the door is released, the leaf A will de'- scend, traversing the inclined or spiral edgeof the projection on the pin b, carrying with it the door, and thus closing the latter.
Spiral hinges have heretoforebeen made by casting o ne leaf upon a spiral project-ion 'formed on the opposite leaf; but a hingeof this character is so expensive to manufacture that it is not available for any ordinary purposes.
All the parts of the above-described hinge may be cast separately and with-out ditliculty, ,and may be quickly connected together; the cost of manufacturing the hinge being such that it-may be economically ein` ployed as a substitute. for ordinary hinges, while all the advantages of a combined hinge and door-spring are obtained.' j
The pin b may be cas ith the projection c upon the same, or the latter may be formed by winding a plate spirally round the pin.
