Of the construction, but the sash are being made of small galvanized iron frames. We certainly think this the Ideal construction for the short span. high eave style with iron gutters and posts. Heems Floral Co. Portsmouth, O. Combination Check and Globe Valve. The accompanying Illustration shows the details of a new valve upon which W. B. Davis, of Aurora, 111., of the firm of W. B. Davis & Co., has secured a patent. The valve is intended for use on steam heating pipes to take the place of two valves, viz., a check and globe or gate valve, where these are now used. Besides the expense of two valves the room taken up is often an Important consideration. Those ac- acquainted with steam fitting know how important it is to keep water from other radiators or pipes from backing up into a set not in use, also to prevent water from the boiler back- ing up into city water pipes or returns on steam runs, all of which is pre- vented by the use of this new valve, in addition to its use as a gate valve. In repairing broken pipes or taking pipes apart the ordinary check valve is not to be depended on. If not in perfect working order the steamfltter is liable to get a bad scalding from steam and water forced back through the Inoperative check valve. In the present valve the disc or plunger can be screwed down hard and there is no fear of anything of the kind hap- pening, while when left open it acts. simply as a check valve. A stub projects from the lower end of the valve stem and when the stem Is turned this stub strikes one of the upper guides of the plunger, caus- ing the plunger to turn also, thus pre- venting it from striking shut when the stem is raised, also causing it to grind out any dirt or scale that might collect on the se^t so that it always closes perfectly tight. The advan- tages of this valve are many. In the first
