ROBERT BUTLER. OF BOSTON, MASSACHUSETTS. CLEANING DEVICE FOR FITTINGS.

Specification of Letters Patent. Application filed Septemhe1'30,1905. Serial No. 230.774.

Patented Nov. 27, 1906.

To all whom it may concern:

Be it known that 1, ROBERT BUTLER, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Cleaning Devices for Fittings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to. a clean-out device or apparatus for passages containing fluid, and is es ecially designedand adapted for use on boi ers, pumps, and like apparatus containing fluid under pressure, and particularly in connection with gages, valves, crosses, Ts, and like fittings. For this purpose I through with fluid-tight joint will be described. I

The plunger-rod may and preferably will be made in two parts a sleeve adapted to be connected about the plunger-rod, as

is applied to the gage-cock of a boiler containing pressure such, for instance, as a steam-boiler-the valve-stem for the gagecock may be employed as the plunger-carrying sleeve, and the plunger may and preferably will be provided with an enlargement or head on its end constituting a valve, which cooperates with the sleeve and with the passage in the valve-fitting which communicates with the boiler, sothat when the plunger-rod is moved into its operative position the head or valve on the end of the rod fits the passage substantially close. The plun er-rod or stem is made of suflicient lengt to extend through the passage and into the boiler, so as to free the passage from any sediment which may have accumulated within the same or at its inlet-mouth. ,Provision may also be made for simultaneously operating both the upper and lower plungen rods cooperating with the upper and lower gage-cocks, so that in case the gage-glass should break the upper and lower passages in the upper and lower cocks may be practically closed substantially in an instant, whereby danger of scalding or otherwise injuring the engineer may be reduced to a minimum.

Theseand other features of this invention will be pointed out in the claims at the end of this specification.

employ a plunger orrod extended.

a fitting and means for rendering a hinged together for a purpose as will be described. When the clean-out device Figure 1 is a side elevation of a suflicient portion. of a boiler or videdwith steam-gages having my improved cleaning device attached thereto. Fig. 2 is an end elevation of the apparatus shown in Fig. 1 looking toward the right. Fig. 3 is a horizontal section on the line 3 3, Fig. 1, showing the plunger-rod in its withdrawn position,- Fig. 4:, a view similar to Fig. 3, showing the plunger-rod partially moved into the outlet-passage from the boiler; Fig. 5, a detail in side elevation, ger-rods in the position represented in Fig. 4. Fig. 6 is a horizontal section through one of the fittings, showing the plunger-rod as inserted through the passage and into the boiler. Fig. 7 shows the device applied to a modified form of steam-gage, and Fig. 8 a detail of the device shown in Fig. 7.

Referring to Fig. 1, (1 represents a steamboiler, pump, cle containing fluid, b an upper gage-fitting, c a lower gage, and d a glass connecting the gage-fittings b and c, all of which areof any usual or suitable construction. Each gagefitting b and c is provided with (see Fig. 3,) communicating with the boiler a, and is further provided with a valvef, having its stem 9 provided with screw-threads 7L and with the usual handle 2', by turning which the valve f may be brought to its seat, so as to close the passage 6.

In accordance with this invention the valve-stem g is made hollow and hasextended through it a plunger or rod 7', provided at its end with an enlargement or head 7c, which is of substantially the same size as the passage e, so as to permit the head 7c to pass freely through the passage 6, yet fit the same substantially tight to throttle or reduce the amount of steam or other fluid which might escape through the passage 6 in case the glass tube (1 should break. I c The hollow valve-stem g constitutes a plunger-carrying sleeve and is provided at its other apparatus proshowing the plunor other apparatus or receptaa passage e, V

outer end with screw-threads which are en- 'The'head 7c maybe to constitute turned up,

- rods y, and thereby In case it is desired to clean the passageie from sediment the member or part 13 is so as to bring it into line with the plunger-rod 7', and the latter is then forced into the passage 6 and through the same into the boiler, pump, or other structure, as represented in Fig. 6, thereby removing from the passage 6 and its inlet-mouth any sediment which would otherwise impede the flow of fluid through the said passage.

The cleaning device for both gage-fittings b and c are the same, and in case the gageglass d should break the cleaning-rod may have the function of a throttle-valve and may be moved into the passage 6, so as to practically throttle the escape of fluid, or at least reduce'the volume of fluid escaping through the passage 6 to such extent as to enable the engineer to turn the valve-stem or sleeve 9 by means of'the hand-wheel j without danger of being s'calded.

Provision may be made for simultaneously moving the plunger-rods 1 into the passages e, so as to throttle the fluid escaping therefrom, and one form of device for accomplishing this purp'ose'is herein shown, the same consisting of two arms 20 and 21, fast on a vertically-arranged rod 22, mounted to turn in suitable brackets 23, attached to the fittings band 0, or it may be'any other suitable support.

The rod 22 is provided with a crank or arm 26, having attached to it a chain or cord 27, shown in the present instance as leading over a pulley 28 and having its lower end placed within convenient reach offthe engineer or other operator, 'so that the latter may by drawing down upon the cord 27 turn the rod 22 so as to cause the arms 20 and 21 to strike against the end of'the clean-out move them a sufficient distance to carry the head k into the passage 6 of the gage-fittings b and 0. Provision may also be made for retaining the cleaningrods in this position against the pressure of the fluid, and for this purpose the upper bracket 23 is provided with a sleeve 30,

\ through which the rod 22 extends, said sleeve having a stop or notch 31, with which the arm 20 cooperates when the said arms areturned to move-the clean-out rods into their throttling position, as representedin Fig. 5,the upright portion of the notch '31 acting as a back-stop to prevent backward movement of'the arm 20 and the rod 22,

tion to the particular invention in this respect, as the said device may also be applied to other forms of gagesas, for instance, as shown in Fig. 7, wherein the steam-gage 40 is connected with the boiler a by means of a pipe 41, having a cross connection 42, to one port of which, in line with the pipe 41, is attached the plunger-containings eeve g, provided withthe stuffing-box 10, the plunger part 13. I

So, also, I do not structures shown, as the plunger-containing'sleeve g, the plunger j therein, and the stuffing-box 10 may be utilized in conjunction with a straight pipe leading from the boiler or other apparatus containing fluid.

It will be noticed that'the plunger-rod ble'from outside thereof, so that it can be positively moved by the operator in opposite directions in the passage e, thereby enabling the said rod'to be worked or moved back and forth by hand in the passage and in this manner removing from said passage any sediment which may accumulate therein. It'will "also be noticed that the cleaning-rod is freely movable,"and as a result the passage 6 can be substantially closed in an instant to throttle the steam in case the glass d should its movement in one directlon by the head it and in the other by the thumb-piece or handle on the rod 13.

I claim 1. The; combination with'aboiler, gageflttings provided with passages communicating with said boiler, a gage-tube connecting said fittings, hollow valve-stems "extended into the said fittings and cooperating with passages leading to the boiler, plunger-rods movable in said hollow stems, arms cooperating with said plunger-rods, 'a support for said arms, and means tom'ove' said support to cause the said arms to operate the said plunger-rods substantially sim'ltaneously, for the purpose specified.

2. The combination with a fitting provided with a passage, a hollow stem or sleeve arranged in line with said passage, a rod eX- tended' through said sleeve and capable of being positively moved in both directions longitudinally in said sleeve 'or hollow stem and provided at one end with an enlargement or head of smaller diameter than said passage to permit said rod to be moved through said passage and to enable said sleeve and rod to be removed from thereby retaining the clean-out rods in their of the latter from the boiler, and means'at operativeposltion against the 'actlon ofthe the opposite end of said'rod to limit the inhaving the jointed desire to limit my invenbreak. Furthermore, the rod j'is limited in the fitting without removal 7 ward movement of the same in said sleeve, substantially as described.
