ANTICHATTEBING DEVICE.

Application filed m a,

This invention relates to an anti-chattering device foruse with pressure gauges and the like, and more particularly to a device of this character which may be readily inserted in the pressure line without resorting to any changes in the construction thereof.

a A further and more specific object of the invention is to provide a member for insertion in the pressure line leading to a pressure gauge or regulator from a source of pressure having means for reducing the effective size of the bore of the line, so that sudden slight variations of pressure are relatively slowly transmitted to the gauge or vregulator, whereby vibration or chattering of the hinge is prevented.

A still further object of the invention is to provide a device of this character wherein a relatively long reduced passage is provided for the purpose above described while employing a relatively short body for the anti-chattering device;

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation showing a pressure gauge, the pressure line of which includes an anti-chattering device constructed in accordance with my invention;

Figure 2 is an enlarged'vertical sectional view through the anti-chattering device;

Figure 3 is a section on the line 33 of Figure 2.

Referring now more particularly to the drawings, the numeral 10 generally designates the ressure gauge or regulator and 11 a conduit eading to the gauge from a source of pressure. In accordance with my inven- ,tion, I insert in this conduit 11 a tubular body 12 tlae ends of which are exteriorly threade as'at' 13, for the reception of re- 'ducer caps 14 which in turn are provided with a reduced threaded bore 15 for the reception of the conduit. The caps provide a sealing connection between the tubular body and the adjacent ends of the sections of the conduit 11;

Disposed within the bore 16 of the tubular body is a rod or tpllunger 17 of slightly great.- er length than c tubular body, so that its ends projecttherebeyond. Suitable means, pins; 18, are provided for holding 1926. Serial No. 121,247.

the rod in position with its ends projected beyond the ends of the tubular body. The periphery of this rod is formed with a spirally extendin groove 19 extending from end to end of t e rod. Through this groove pressure transmitted to the gauge must pass and accordingly since the groove reduces the efl'ective size of the bore of the gauge conduit, the speed at which the gauge will respond to sudden variations of pressure is reduced. The groove may be constructed in accordance with the articular'needs of the gauge with which it is to be employed.

tively rapidly, the spiral may be more closely formed and the groove reduced in size. In order to. further increase the resistance to sudden impulses, the groove is preferably formed in sections, a jacent ends of the sections being cireumferentially oflset axnd connected by circumferentially extending grooves 20. The sudden change in direction thus provided efiectually checksany tendency to sudden motion.

It will be obvious that a device of this character may be readily inserted in the gauge or regulator line without any manner altering the line other than by removing therefrom a section of a len h equal to the length of the device. In a dition to being readi y installed, the device may be readily cleaned as the rod or plunger may be removed at an time and any obstructing accumulation c eaned from the groove.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the s irit of the invention, I do not-limit myse f to such specific structure except as hereinafter claimed.

I claim In an anti-chattering device and in combination with a pressure responsive element, a. line leading from a source of pressure thereto, a member adapted for insertion in said line increasing the efiective length of the line a distance greater than its own length and reducing the bore of the line tubular body whereby it is held with its ends comprising a tubular body adapted at its extended beyond opposite ends of the tubuends for connection with the pressure line ler body, said groove being extended to such 10 and a rod fitting the body and having a. ends. I

5 spiral groovein the periphery thereof, said In testimony whereof I hereunto aflix my rodbeing of greater length than the tubular signature. body and having means coacting with the DOC GILFORD TAYLOR.
