Application filed December-17,1909. Serial No. 533,621.

,Toall 'whom may concern:

Be it known that I, CHARLES J. MAGKERni,

a chief machinists mate, U. S. Navy, citizen of the United States7 residing at Newport News, in the county of lVaiwick and State of Virginia, have invented certain new and useful Improvements in Valves for- Steam-Traps and the Like, of which the following is a specification. I

My invent-ion relates to certain new and 4 useful improvement in steam traps, and the object of my :invention is to provide a trap of this character which will be simple` in construction, positive and accurate in its operation, composed of but fewpaits and not likely to get Aout of order.

lVith these and other object-s in View my invention consists in certainconstructions, combinations and arrangements of parts the preferred form of which will be first described in connection with tli'e accompanying drawings and then the invention particularly pointed out in the appended claims.

Referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a central longitudinal section of the trap constructed in accordance with my invention, showing the parts in the position they assume when the draw oil valve is closed; Fig.'2 is a similar view showing however the draw oi' valve open.

Itis desirable in steam traps of the type in which my invention is embodied that a certain amount of water be retained in the trap 'at all times, and that as soon as the water passes a predetermined level it be drawn ofi' until said level is again obtained.

3 designates a casing for the trap which is closed at its upper end by the head 4.

5 designates a pipe which extends from any main oi' other vapor carrying part from which the condensed liquidl is to be trapped. This pipe is shown asfbeing provided with a valve 6 and extends into-the top of` the head 4.

7 is a draw off pipe which extends through the head 4 down near the bottom of the casing 3. This pipe at its lower end is provided with any desired form of valve structure 8, that 'shown for the sake of illustration being the same as illustrated in my pending application No. 512,722, filed August 13, 1909, it only being necessary that this valve be of such a type that it can be opened and closed by the oscillation of an arm 9 pivoted Vagain niovefth'e parts to the position shown at .one end to a standard A10 formed on the f valve ;8. Asshown thevalve is provided.

`with a reeiprocatin'ggate or plate 11 which is connecte to the rod 9, so that when the ,rod Ais raised the plate will be' raised and the valve o cned, and when the rod isloweredthe v ve will .be closed 12. designates an open top rece tacle which v is smaller than the casing 3. nnected to this receptacle is a rod l'which, in the rticular construction shown, isconneeted to the bottom of the rece taele by a nut 14 clamping the bottom 0, the receptaclebef tween it and a collar 15 formed at the lower `end of the rod.

Tlie'rod extends out through the'stuing box 16 inthe head 4 of the'casing, and is connected by a link 17 to one end of'aflever 18 pivoted at 19 to a standard 20, projecting' from the cover 4, said lever also carrying the adjustable weight 21 which can be slid along `i the lever andv securedin position'b sired means as a set screw 22. Tli tacle `12, as will be seen from the drawings, receives all liquid through the pipe 5.

' 23 is a rod pivotally connected at its lower end by means o f a pin 24 passing into -a slotf '25 formedadjacent the end of the lever 9.

This rod at its upper end passes through a flowing into the Atrap stuffing box 26 formed in thehead tand pipe 5 is received in the receptacle 12, which is held in the position shown in Fi'g. 1 until the accumulation of water therein counter# 'is connected 4by meansof a link 27`to the lever 18 on the opposite side of the pivot 19 balances the weight `21', whereuponthe receptacle will move down, pulling down the,

lever 18 which will pullup on the rod 2 3 and through the lever 9 open the' valve, permitting the accumulation of water in. the

trap to pass out through the ipe 7. As soon as the weight of-water in t e receptacle is insuflicient to counterbalance'the weight-21 the parts will be returned to theiroriginal-- osition, as shown Fig. luapd willreri'i'ain 1n such position until there isa suflicient accumulation of water in the `,receptacle to in Fig. 2, opening the valve 8. A

4I realize that considerable variation .1s possible in the details of construction and arrangement of parts without de arting from the spirit of my invention, 'an I therefore do not intend to limit myself to the specific form shown anddescribed.

What I claim 'as new and desire to seoure by Letters Patent is:

1. In' a, steam trap, the combination with a closed casing, of a receptacle-within the easing and separated therefrom, a gated valve within the reoeptacle and out. of 0011-' I tot therewith, a lever within the receptacle and connected tothe gate of said valve for operating it, an overflow pipe leadingifrln said valve, a lever exterior to the casing, a. rod connectin receptacle, an a second rod connecting the -ie'xterior lever with the valve lever.

2. In 'zt steam trap, ,the combination with l e closed casing, of ereceptacle within said .casing and separated therefrom,` a `valve within said receptacle and out-of contact Y.

therewith, lan overlowppe leading from said valve, a'. 1ever 1n ounted on th outside ,level-Q Ae rod connect-in the exterior lever with the weight adiustably mounted on said lever.

to oper'atethe same', and'a second rod conof the' casini, a rod extending from the i receptacle an 'securedto the lever a second 25' lever connected to the .valve and adapted nect-lngzsaid lever outside the casing with said'valve operating lever, and a ,counter-f weight onsaid lever outside the cas'ing.

, Y 3. IIn a tralp, the combinationwith a; 'closed casing,lof'e receptacle within the casing and sepa-retedxtherefrom, af valve within the. receptacle and out of 4Contact therewith," means -for operatingy said valve, an overow pipe ,leading fromaid valve, e said lever with the :receptacle and, a ,seoon rod connecting said -lever with said' operating-.meansL-nnd -u
