GeneraZDescr/@tion by Letter.
In the central cross piece or stile of the door A is` made a deep niortise or cavity, in which an elastic rubber spring, D, is placed, double or single, as may be required, one end of the spring being secured to the loop or staple E,lwhich is let in fiush into the jamb o f the door or casing B, the spring passing inl between two frictionlrollers f j, secured vertically in the edge stile of the door A.
The other end of thespring D is secured to a. windlass, g, placed centrally, or thereabouts, in the middle stile, it being so constructed that it may be turned to tighten up the spring, and held by a pawl or latch.
The portion of the rubber spring D that connects with the staple Ev -in the casirg', and bears upon the friction-rollersff, may and should be made thicker than the port-ion contained within the recess, which will give it more durability without making it mor rigid.
For large, heavy doors, it may be desirable to insert two or more of the rubber springs, the recess in the door being proportionably large to receive them.y
WhatI claim as my invent-ion, and desire to secure by Letters Patent, is-
The windlass g, or an equivalent device for tightening an elastic rubber door-spring, when 'both are in serted in the body of the door, and arranged to oper ate substantially in the manner as and for .the pur-
