Abstract: A one piece molded combination retaining housing and tee, and a one piece molded combination retaining housing and 90.degree. elbow, for new installations of lawn watering systems, and a separate retaining housing for use with conventional tees and 90.degree. elbows in existing or new installations of lawn watering systems, to eliminate foreign matter from entering into the underground water piping system when a pop-up head is removed for repair or replacement. Adapters, to increase the height of the retaining housings, and retaining housing caps to allow standardization of the retaining housings of these three parts are also a part of the invention. All parts would be made of PVC today, but the material would not be limited to PVC.

Abstract: An improved eating fork having a conventional handle, an extended flat body portion and a plurality of short conical tines each having a small smoothly rounded end. The short tines project along parallel axes from the forward end of the flat body portion extending from the fork's handle. The body portion has a width slightly greater than the distance across the bases of the plurality of tines. The flat body portion of the improved fork contains in its upper surface a generally rectangular depression. The tines have a length about one fifth the length of the fork's flat body portion. The surfaces which join the tines to the flat body portion are all curved and all surfaces of the fork are polished during manufacture of the fork.
