Grinriell Company, Inc. Heating and Piping Systems The Grinnell Equiflo Valve for types of Power Plant and Indus forced hot water heating accom trial Piping including Automatic plishes: Sprinkler Systems, piping for Acids, 1. More perfect equalization of flow to Alkalis, etc., Compressed Air every radiator than has ever been practical by even the most careful calculation of pipe sizes. Size or location makes no difference. 2. The introduction of sufficient fric tional resistance to completely over Cleaning Systems, Humidifying Systems. A contract placed with Grinnell Company is carried out to the satisfaction of all concerned. Materials of the highest quality are come that trouble so pronounced in most forced hot water heating sys tems which is due to the well-known war between pump head (a constant) and the gravity on temperature head (a variable). This insures absolutely equalized circulation at all tem peratures. 3. Lower pumping costs. The Grinnell Equiflo Valve: 1. Serves as the regular shut-off valve for each radiator. It is of the pack less type. used. Grinnell Adjustable Hangers and Grinnell Fittings, for instance, save work in installation and make for cleaner, more satisfactory fin ished jobs and lower maintenance costs.

Grinnell Adjustable Hangers ONE of the chief advantages of Grinnell Adjustable Hangers is that they permit adjustment of pipe lines after installation, thus obviating the necessity of turn buckles or the removal of hangers. And their time and trouble-saving qualities during installation are equally exceptional. On this and the two following pages are shown a few Grinnell Hangers of particular interest to heating engineers. The Grinnell Hanger Blue Book, however, illustrates and describes the complete line and carries mechanical drawings and dimensional tables on practically every hanger shown. This feature alone makes the Grinnell Hanger Blue Book invaluable to Engineers, Architects and Draftsmen. As many copies as you require will be sent on request. Adjustable Swivel Ring--Solid Ring Type (Patented October 4, 1921) THIS Malleable Iron Adjustable Swivel Ring can be used with Coach Screw Rod or Machine Threaded Rod in connection with practically any type of Ceiling Flange, Expansion Case, Insert, etc. . The unusual feature of this ring is the Swivel Shank. An adjustment of at least 1^ in* is secured by simply turning the nut on the shank. No temporary support of the pipe line is necessary while making adjustments. By means of a unique locking device the Swivel Shank automatically locks, preventing loosening due to vibration in the pipe line. Fig. No. 104 Adjustable Swivel Ring--Split Ring Type (Patented October 4, 1921) THE Split Ring Type of the Adjustable Swivel Ring was also designed for use with Coach Screw Rod or with Machine Threaded Rod. The Swivel Shank allows the same adjustment as in Fig. No. 101, either before or after the hinged section is bolted in place. The off-center hinging of the Ring provides sufficient seating to hold the pipe before closing the Ring. By means of the same locking device as in Fig. No. 101, the Swivel Shank is automatically locked, preventing loosening due to vibration in the pipe line. Fig. No. 85 Universal Side I-Beam Clamp (Patented April 6. 1915) ADAPTABLE to many uses, this Side I-Beam Clamp has ample strength for hanging % to 12 in. pipe from I-Beams. This Clamp in different sizes will fit all sizes of Standard and Bethlehem I-Beams, and most sizes of Bethlehem Girder Beams. Under conditions requiring vertical adjustment of the pipe line, this Side I-Beam Clamp is used with an Extension Piece or an Extension Eye Bolt. Fig. No. 86 Universal Channel Clamp (Patented April 6, 1915) DUE to the adjustability of the Grinnell Channel Clamp, three sizes of these clamps, with varying lengths of clamp rods, will meet most of the conditions encountered' in practical installation work in connection with'channels. We know, of nothing else on the market which will obviate,,the necessity for the making of specials for Channel Iron work. 515
