To all whom it may concern:

Be it known that I ALBERT BEST, a citi-- zen of the United States, resid ng at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bushings for Radiators, of which the following is a specification.

This invention relates to bushings for radiators. I

The appliance is particularly adapted for in the hot water is introduced at one end of the radiator and passes out at the opposite end thereof.

One of the objects of the invention is to radiators.

Another object is to provide an improved bushing or intake coupling for hot. water radiators.

Another object is to provide a bushing or coupling which will increase the efficiency of a radiator and. protect the same when not in use.

Another object is to provide a bushing or. coupling which will direct hot water toward the top of a radiator, will drain the radiator when the same is turned off, and which will serve to keep cold water from flowing from the second loop of the radiatorintothe first loop thereof. I i I Another object is to provide a simple, in

expensive, efiicient fitting in form of a bush- Hot water radiators come to the user with T inlet and outlet openings larger than required for the stem of the valve to be inserted therein and a bushing is required to eilectively reduce the opening to accommodate the valve. Furthermore, radiators of this character, have communicating open-1' ings between the loops near their upper ends upwardly as well as similar openingsnear their bottom ends.

The device herein disclosed serves as a bushing forthe valve and to forcibly direct the incoming water upwardly through the first loop of the radiator from which pointv it is distributed laterally through the'horizontally extending upper openings and downwardly through the respective loops to the opposite end to the return pipe.

The fitting is provided with an angular flange 5, an outwardly threaded part6 for insertion in the first loop 'Zfof the radiator and an inner threaded part 8 to receive the valve used to control the flow of; water through the radiator. I e

The device extends inwardly ofthe loop 7 so that its rear wall9 is in substantial or partial contact with the short nipple 10 that joins the loops ,7 and 11 The wall 9. is curved as at 12 to cause the water to flow ,thru loop 7 and thru'the opening 13. y v

The fitting is. provided with a very small i hole or by-pass 14: inits bottom wall in the "same vertical planewith theopening 13 for permitting the water to drain out of the first leg of the radiatorto prevent freezing when otherparts of the radiator are drained of water. The hole is so small asnot to ma terially interfere with the general circulation of the wateras heretofore pointed out.

In the event that rear deflecting wall 9 does not tightly fit against the adjacent end of bushing 10, and ordinarily because of irregularities, etc., this is the case, it has been found in practicethat the by-pass 14L serves a to prevent the flow of cold water from the second to the first loops of the radiator. Thus the intermixture of cold and hotwater in the first loop of the radiator is lessened, I

and theefliciency is increased. i a i The flange 5 bears a mark 15 to indicate the position ofthe opening '13 when the de vice is screwed into a radiator.

Having described my invention, what I 7 claim as new and desire to secure by Letters Patent, is: i I l. A radiator bushing having a single pipe connecting passagetherethrough, a deflecting wall for interpositionbetween the first and second loops of the radiator and serving 1 to direct the incoming water upwardly in the first loop, and aby-pass interconnecting the.

"first and second loops.

and serving to direct the incoming water upwardly in the first loop and a icy-pass through the lower portion of the deflecting wall, sa-icl by-pass serving as "a drain, and to prevent cold water flowing from the second 10 loop to the first loop. 5 tween the first-and seconcl loops of a radiator In testimony whereof I hereunto subscribe my name.
