DEHYDRATOR Filed July 29, 1929 fIEIl 1 l6 zz 15 gwuentov Patented Jan. 5, 1932 UNITED STATES PATENT OFFICE FRANKLIN G. SLAGEL, OF BUFFALO, NEW YORK, ASSIGNOR TO FEDDERS MANUI'ACTUB- ING COMPANY, INC., OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK DEHYDRATOB Application filed July 29, 1829. Serial No. 381,977.
This invention relates to refrigerating systems and more particularly to dehydrators. An object of the invention is to rovide a unit structure which can be readi y associated in the circuit of a refrigerating system for absorbing water from the refrigerant in its cyclic travel therethrough. 1
Another object of the invention is to provide a unit structure which can be readily 1 associated with and detached from the circuit of a refrigerating system for filtering the refrigerant in its cyclic travel therethrough.
A further object of the invention is to pro- 15 vide a dehydrator for refrigerating systems which is formed of sections which are removably secured together so that a filter and calcium chloride can be removed and renewed.
Other objects of the invention will be apa parent as the description of the invention progresses.
In the accompanyin drawings, Fig. 1 is an elevation of one en of a de ydrator incorporating the invention; Fig. 2 is a longitudinal medial sectional view of the dehgdrator; and Fig. 3 is an end elevation of t e other end of the dehydrator.
Referring now to the drawings by characters of reference represents the body of 39 the deb drator which preferably formed as a cy indrical casin having an end wall 11 having an internal y threaded inwardly extending circular flan e 12.
A filtering unit pro ects through and is secured in the end opening formed by the threaded flange. Such unit includes a hollow supporting member 13 having a circular open portion .14 threaded externally and adapted to screw into the threaded flange of the housing. The supporting member has a shoulder 15 for limiting the insertion thereof into the end of the housing, and the portion 16, adjacent the shoulder, is formed in hexagonal shape for the application of a wrench when the unit is to be applied to or removed from the housing. The outer end 17 of the supporting member is flared and threaded so that a conduit in the refrigerant circuit of a refrigerating system can be readily attached 50 thereto.
The supporting member 13 carries filtering means, and to this end a perforated anchor plate is soldered within the hexagonal portion 16. A cylindrical screen 19 havin a cloth cover 20 is seated within the threaded end 14 of the housing and a cap 21 is arranged to cover the other end of the screen. A rod 22 is soldered to the central portion of the anchor plate and the other threaded end thereof projects throu h the cap 21, a nut 23 being screwed on t e end of the rod to clam the screen with the su porting member. he screen is filled by t e spon e 24. It will be seen that by removing t e nut, the cap and screen and its cover can be removed from the supporting member so that the sponge can be cleaned or removed. The unit is soldered to the end of the casing, as indicated at 25, and the solder is of a slight amount so that the joint can be broken by unscrewing of the supporting member.
The other end of the casing supports andis closed by another combined filter and union. A cap 26 is provided with a threaded flan e 27 which is screwed upon the open end of t e casing member 10, a portion 28 of such cap being hexagonal for the reception of wrench. The end 29 of the cap is formed as a threaded nipple for attachment in thecircuit of the refrigerating circuit. The end of the casing is turned inwardly forming a flange 30 which is threaded, and a portion 31 of the cap is threaded so that a soft metal washer 32 will lie adjacent it and the threaded flange of the casing. As the cap is screwed'on the end of the casing, the washer will be clam d between such adjacent threaded portlons to form a leak proof joint. A cu member 33 projects into the end of the b0 y and has a flange 34 overlying the flange 30 and held in position by the sponge 35 which fills the space between the cap and the cup member, the major portion of the inner wall 36 is open and a removable screen 37 seated within the cup member covers the opening.
By unscrewing the cap member 26, the sponge can be removed and cleaned or replenished, and if desired the cup member and screen can also be removed. The space in the cylindrical body unoccupied by the filtering devices is filled with calcium chloride, and by removing either one or both of the filtering devices the calcium chloride can be removed from the body and a new supply added. Refrigerant flows through the filtering dcviccs and the calcium chloride when the structure described is inserted in the circuit of a refrigerating system in which refrigerant travels in cycle, water being ab sorbed therefrom by the calcium chloride and foreign particles being removed from flowing in the circuit by the filters.
Various changes can be made in the details of the structure described without departing from the spirit of my invention and the scope of the claims.
What I claim is:
1. In a purifier for a refrigerating system, a calcium chloride container, a pair of means for connecting the container in the refrigerant circuit of the s stem, and refrigerant filter means in each 0 said connecting means.
2. In a purifierfor a refrigerating system, a container adapted to be filled with water absorbing material, removable inlet and outlet members connecting the container in the refrigerant circuit of the system, and filter means carried by each of the connecting members, said filter means being removable from the container.
3. In a refrigerant purifier adapted to form part of a conduit for refrigeratmg systems, a cylindrical container having an end wall and adapted to contain a water absorbing material; and a unitary filtering unit extending through the end wall of the container, said unit comprising a hollow supporting member screwed into the container end wall and having a conduit receiving exterior end, a screen partially telescoping the inner end of the supporting member, anchor means engaging the inner end of the screen detachably securing the screen to the supporting member, and a sponge filling the interior of the screen.
4. In a refrigerant purifier adapted to form part of a conduit for refrigerating systems, a cylindrical container ada ted to contain a water absorbing materia said container having an apertured end wall; a hollow supporting member screwed into the container end wall and having an exterior end adapted to be secured to a conduit, and filtering means associated with the end of the supporting member and extending into the container, said filtering means being removable from the container with the supporting member and detachably carried by the supporting member.
5. In a refrigerant purifier adapted to form part of a conduit for refrigeratmg systems, a cylinder adapted to contain a water absorbing material, and a pair of removable filter containing outlet members connecting the ends of the cylinder in the system, one of said members comprising a tubular supporting member screwed into the end of the cylinder, a rod fixed to and extending axially through the inner end of the supporting member, a. tubular screen telescoping the portion of the rod projecting from the end of the supporting member, a cap on the pro jecting end of the rod, and removable means associated with the rod to secure the cap against the screen, said cap holding the screen against the inner end of the supporting member.
In testimony whereof, I have hereunto signed my name this 16th day of July, 1929.
FRANKLIN G. SLAGEL.
