This invention relates to that kind of relief valve designed. to rem ve the water of condensation from radiators, steam coils or other parts of a steam heatingsystein in which a low pressure or partial vacuum is maintained in the return end in Whicha lioat is used to automatically control the discharge of water withoutv Wasting any steam.. Such relief valves, more specifically calledsteam traps, become frequently vinoperative inostly from no other cause than from an accumulation 'of ,scale or rust in the systeni which when it happens with the steam traps in present use necessitates the taking dit' of the cover and changing the parts Uy hand.
The/ object of my invention is to provide simple and efficient means for cleaning out 'the valve without the necessity ofdismounting any )art thereof all as more fully here.`
inafter escribed and shown in the accompa 'ying drawings, in which l igure `l is a vvertical central section [through a relief valve embodying my ln vention and showing the parts in operative position. Fig. 2 is a detached and enlarged Reference being had to the drawings by iufn/ierals, 1 `indicates the casing inclosing the float 2, 3 is the steam inlet and 4 the ontlet for the water of condensation. The float is vertically guided inthe casing by means of an open ended hollow ,guide stein 5 secured in the outlet'opening and forming yat (3 a `shoulder on which the lloat is adapted 7 through which the interior of thev casing communicatesl with the outlet under the control of the float. rl`he float is provided with a seat 8` and, with a guide bearing `8 adapted to guide ythe float upon the stern 5.
` 'l`lie'l parts above described form a.` relief `valve of' known construction and Operation and serve merely to illustrate the use of my invention which `consists in providing the Speccation of VLetters Patent. Application f iied August 13, 1909. sensi No. 512,644.
Voutside in a handle l2.
upon its seat, the guide stem `the friction of the rod in the 'Patented Feb. il
float with. a twopart lifting rod 9 and lt) the part 9 of which is rigidly secured to .the top of the 4rfloat-and the Other'part 10of whichslidingly passes through a stuffing" bony l'lon top of the casing and terminating and. 1.0 are connected inside the casing by a sliding Joint formed in any suitable manlhe two parts 9' ner to accomplish tliedesired object. 4 As shown in the drawing the'part 9 is tubular and is connected to the top part 10 by a pin 13 which freely limited length formed in the part 10.
` The parts being arranged as shown and described it will readily .be seen that by .means of the lifting 'rod the'oat can be variously ,manipulated by handI from the outside without dismounting any part, thus byipulling: it up the openings T can be fully uncovered `and the steam given full chance and by repeat-` to blow ont any obstruction edly jigging it up and down and turning it and valve seat caw-be freed of any sediment interfering with lthe operation of the float. lf the rod is pushed down as far as it will go the float can be firmly seated upon Ithe shoulder 6 and stufling box w1ll. ir'mly hold 1tdown, it thus acts as a 'very convenient shut oli' in cases of repair oi"(.'.hangcs in the system of for the purpose of accumulating a greater amount of water in the system for blowing out purposes. To permit the float to seat itself freely upon the shoulder the connection between the parts 9 'and 10is made as shown vto afford some `freedom for lateral' play. k
lVhat I claim as my invention is zln a. steam trap, th`e combination with the elsing and iioat inclosed therein, of a twopart Alifting rod having its` lower portion secured tothe lioat and extending within the easing and an upper portion slidingly snpportcd @n thecasing and extending without the same, th-Jtwo parts `being connected together within the casing by a lost. motion connection. i
ln testimony` whereof I allix my signature in presence of two witnesses.
