UNITED STATES PATENT EETCE,

DIAPHRAGIVI FOR PRESSURE-REGULATORS.
,EDEICIFICATION forming part of Letters Patent No. 335,033, dated January 26, 1886. Application filed December 17, 1885. Serial No. 185,918. (No model) To @ZZ whom t may concern,.-
Be it known vthat I, N ATHANIEL C. LooKE, a citizen ofthe United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Diaphragms for Pressure-Regulators, of which the following is a specification.
These diaphragms, shown and described in my application No. 92,755, have the extended edge or margin clasped between fianges and the centrall part inverted so as to form adeep annular corrugation or fold. Heretofore these diaphragms have been made in the form of a plane cylinder with one end closed and a laterally-extended flange around the open end. The closed end being inverted and forced into the open end, necessitates its reduction to the diameter of the interior of that portion into which it is forced, causing a puckering and crowding which sometimes prevents its free and easy action in use. It will be observed that any heavy rubber fabric containing layers of cloth cannot beforced from its natural shape and form Without more or less straining the canvas, and especially would this be the case when subjected to severe pressure.
The object of my invention is to prevent this wrinkling and provide a diaphragm thatshall allow the piston to move with more freedoilili 3o when under great pressure; and it consists in forming its upper and inner part smaller thanl the lower and outer portion. (t
Figures 1 and 2 are vertical sections.
In Fig. l is shown a diaphragm as it comes from the molds, having its upper portion contracted, as shown at at, to nearly the diameter of the interior of the base.
Fig. 2shows the diaphragm in working position, with laterally-extended edge a5 clasped between anges a and a2, having piston a3, located Within the upper portion, c, which is made to occupy the interior of the lower portion from at to the base.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, iS
A diaphragm constructed substantially as herein shown and described, having that por' tion from c? to a6 made smaller in diameter 5o than the base portion and adapted to be folded in upon itself, as shown.
NATHANIEL C. LOCKE.
