IMPROVEMENTV iN STEAM-PRESSURE REGULATORS.
Specification forming part of Letters Patent No. 136.202, dated February 25, 1373.
Object of the I mention.
When pressure-regulators are used in regulating the pressure of steam in drying-cylinders, such as are used in paper-machines, slashers, Src., itis desirable that, when the machine is stopped afterhaving been started, the pressure of steam in the cylinders should be instantly reduced; otherwise the paper or yarn, being manufactured becomes too dry, and vice versa, when ,the machine is again started to run, so that simultaneously therewith the required pressure shall be brought back to the cylinders. My invention consists vin a new and peculiar arrangement and combination of devices, by means of which, when the machine is stopped, the valve in the pressure-regulator is closed, or nearly so 5 and 'when the machine is again started the valve is allowed to be controlled by the regulator, and the steam instantly brought back to the required pressure4 in such a manner that the goods being manufactured will be dried with perfect uniformity.
Description of the# Accompanying Drawing.
yFigure 1 is an elevation, and is designed to represent a pressure-regulator and the driving-shaft and pulleys of a Slasher; also the shippers, levers, andother devices embodied in my invention.
vpiston resting on the diaphragm. 1c is the pipe to convey steam or water to the diaphragm. f'isthe weighted lever; g, theweight to regulate the pressure on the diaphragm. z' is a connecting-rod connecting lever f to valve-'lever' b, all of which, except rod i, are
constructed in theusual form ot' pressure-regulators. mis the driving-pulley on Slasher; n, the loose pulley; o, the Shipper-rod that ships the belt from the driving `to the loose pulley, and is connected to handle p which is used to start and stop the machine in the usual manner. r is a lever hanging loosely on thel hub or stem of valve c, and having an arm, t, extending out from it at nearly right angles, and so formed that when lever p is thrown forward the arm is brought in contact with valve-lever b, as is shown-by dotted line. c is a rod connecting lever r to shipper-handie p. is a spiral spring connecting valvelever b to lever f, as shown. It will be seen .that in rod li there is a slot from pivot s to end of rod7 and that sprin g a', drawing upon levers b and f, holds the upper end of the slot o in rod i, through which the free end of lever j' passes down upon the upper edge of the latter, and the sidefof guide-slot u against pivot s; or the upper end of Slot u may be termi- -nated at pivot .s' in Fig. 2 and made the bearing-pointofrod on lever f, instead of slot o, as Shown in the dra-wing; but when shipper pis drawn over so as to ship the belt upon the loose pulley n, arm tis thrown up against valve-lever b and closes the valve, while the weighted 1evei'fdropsdownin consequence of the reduced pressure of steam on the diaphragm, these motions of the levers b and f in opposite directions being allowed by the slots in the lower end ofthe rod i. In this connection also itis proper to state that the rod lo, which connects the ship'per-handle p to the lever T, should, as a rule, .be made long enough not to entirely close the valve a, so as to allow steam enough to pass to keep the cylinder warm.
" Fig. 2 represents a partial vertical section, the better to illustrate some of the working parts of the regulator.
Corresponding letters indicate the same parts in each view.
The operation is, then, asfollows: Shipperhandle p being thrown forward to start the machine, valve a is opened by the force of' spring fr, and sufficient Steam passes into the cylinder to dry the goods by the time the ma chine starts; then the valve is controlled by the diaphragm, and a uniform dryness is maintained. When the machine again Stops the valve closes, as before. Thus it will be seen that, with the Weight gland rod v properly adjusted, though the machine is frequently stopped and started, the goods manufactured may be evenly dried to any degree of heat desired.
. Claims. Having described my invention, whatI claim 1. The combination, substantially 'as described, of the slotted rod i and spring a: with the leversb and f, for the purposes described.
2. The lever 1), connecting-rod c, lever i, and arm t, in, combination-With lever Vba of 'valve a, as and for vthe purpose 'set forth.
3. The combination of the shipper-roda and its actuating-lever with the adjustable pressure-leverf and valve-lever b of an automatic pressure-regulator, the Whole operatingin the manner and by means of devices substantially as described, for the purpose set forth.
