STEAMTRAP.

To all reliant it may concern Be it known that l. CHARLES J. h'Liclinnnr, a citizen of the l'nited States. residing at United States ship Illinois, Navy Yard, Philadelphia. in the county of Philadelphia and State of Penusvlvania, have invented certain new and useful Improvements in Steam-Traps, of which the following is a specification.

This invention relates to steam traps, and more Inu'ticularly to steam traps designed for use on moving bodies, such as boats, for collecting ccndenscd steam in a steam circulatory system from whence it may be re-introduced into the boiler.

)ne object of the present invention is to provide a simple and practical steam trap which will be cheap to manulzu-ture and install.

Another object is to provide a steam trap that will be highly efficient in operation and not likely to get out of order under unusual conditions.

A further object to provide a steam trap which will permit of convenient manipulation, adjustment and assembling of parts. I,

Other objects will be in part obvious and in part hereinafter printed out.

The present invention accm'dingly coir sists in the features of ccnstructicn, combination of elements and arrangements of Similar reference characters denote corresponding parts in the figures.

Referring now to the drawings in detail, denotes a collecting tank located in any convenient part of the circulatory system, provided at the top with a valved inlet 5 through which the steam and condensed vapor may enter, and at the side with an outlet 7. Between the inlet and outlet is a valve and valve controlling mechanism Specification of Letters Patent.

Application filed February 28, 1914.

adapted to permit the proper discharge of condensed steam under varying conditions.

The valve mechanism is located in a chamber secured to one side of the tank 6, and is provided with a sealed cover 9 which may be removed at will for replacing parts of the valve it' required. A valve seat 11 is located in the top oi. the cutht 7 and co-acts with a reciprocating valve 10. the stem 12 of which passes through a threaded plug 13. The upper pa t of the stem is threaded and carries a lower collar 15 and an upper c01- lar 1 L, adjustable as desired to regulate the time of actuation, while the top is provided with a head 16 engaged by the forked end 17 of the part 18 ot' the valve stem. This part 18 passes through stufling box 19 and is provided with an actuating hand wheel 20. Thus by turningthis wheel 20 the valve may be held in either open or closed position, or when in its intermediate position an automatic operation of the device is permitted as will be hereinafter described. A s ale 21 is provided on or adjacent the part 18 in order that its pcsiticn may be determined on inspection.

The valve actuating mechanism, a part of which is shown in Fig. 3, comprises a. bucket 52) carried at one end of a lever mechanism pivoted in a hollow casting 23 secured to the side wall of the tank and provided with a forked end 24 passing through an opening 23 into the valve chamber and engaging the valve stem 12 between the collars H and 171. This lever mechanism is made of hollow piping. the fulcrum 26 having an opening 27 comnumicating .with the hollow casting 23. Two pipes 28 connect the fulcrum with the ends of a T member 29, which in turn is connected with a siphon pipe 30, dipping down into the bucket. By having two pipes 28 connected in this manner there is less chance of binding at the fulcrum for example if the device is in use on a boat where rolling prevents the device from always occupying a normal position.

Communication is thus established from the bettcm of the bucket 22 through the pipe 30, T-member 29, arms 28, fulcrum 26, hollow casting Q3, thence through the opening to the valve chamber. The water or liquid will then pass through holes 31 in the pipe 7 and out therethrough when the valve is open as shown in Fig. 2.

The operation .of this device is substantially as follows: The condensed steam or vapor entering through the inlet 5 will gradually fill the tank and cause the bucket to rise, and the forked end '24; will bear down on the collar 14: and hold the valve 11 closed. When further upward movement of the bucket is prevented by engaging the top of the tank for example the water will flow over the top and till the bucket, thus causing it to sink. lhe forked end 24 will then co act with the upper collar 15 andraise the valve 11 and the steam pressure will force the water out of'the tank through the pipes and hollow connections as above described. As long as the pipes are filled with Water there can be no material escape of steam, and as soon as the bucket is substantially empty it will rise to the surface of the remaining water in the tank and automatically shut off the valve until the tank is again filled. By turning the valve wheel 20 the valve may be permanently closed as when making repairs, or permanently open as when blowing out the connections with steam. It will also be noted that the present construction permits of ready removal of the valve parts. The side of the tank 6 to which the mechanism is secured may be easily removed by loosening the connecting bolts 32 and the parts of the casting 23 may be separated by removal of bolts 3. In a similar manner the cover 9 may be removed and by loosening the plug 13' the valve and valve stem may be drawn out and replaced as desired.

It is thus seen the invention provides a simple and practical device adapted to accomplish among others all of the objects and advantages above set forth.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made, without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawing shall be in terpretcd as illiistrative and not in a limit in sense.

aving thus described my invention what nation, a receptacle having means outside of said chamber having lost nuance I claim as new and desire to secure by Let- 5o ters Patent is:

1. In a steam trap mechanism, in combination, a tank having an inlet, a separate valve chamber having an outlet, a valve in said chamber, means within the tank operative through the dividing partition for actuating said valve said actuating mechanism including a float adapted to fill with liquid when the tank is substantially full and a pair of pipes leading from the upper part of said tank adapted to prevent lateral movement thereof, said valve chamber having a removable side to permit access to and removal of the valve mechanism.

2. In a steam trap mechanism, in combination, a closed receptacle having an inlet, a separate valve chamber adjacent said rcceptacle, having an outlet therefrom, a valve in said chamber, valve actuating mechanism comprising a pair of pipes fulcrumed in the dividing wall between the receptacle and valve chamber carrying a second receptacle motion connection with said valve, a cover for said valve chamber permitting access to the valve, said parts being positioned and arranged to permit removal of the valve from said open ended pipe without disturbing the means for manually operating said 1 valve.

In testimony whereof I affix my signature in presence of two witnesses. I
