Adjustable Wall and Column Radiator Brackets (Patents Pending) THE bracket on the right, Fig. 190, is designed to support a single tier of wall radiation. A similar bracket, No. 191, is designed to support a double tier, one in front of the other. The bracket on the left, Fig. 189, is designed to support the legless type of column radiation. IIII Only one bolt is necessary to securely fasten these brackets to the wall. This means low installation cost and it cuts drilling holes down to a minimum. Cost of installation can be further I** reduced by spacing these hangers farther apart than ordinary type of weaker construction, especially where Fig. No. 169 hook bolts are set in the wall. When hook bolt is used, it can be set without extremely accurate measurements, due to the liberal range of vertical and horizontal adjustment, and as only three points of the bracket touch the wall, the difficulty so often experienced with rough brickwork is practically eliminated. Adjustable Wall Coil Hangers (Patented May 20, 1913) THE Adjustable Wall Coil Hanger can be furnished with four separate brackets--two for single coils and two for double coils. The brackets locate the center of the coils 2K or 0M in. from back of bracket. Where double coils are used the second hangs 3% in. in front of the first. Besides the adjustable advantages of these hangers which permit the hanger plate to be raised or lowered to secure perfect pipe alignment, it is only necessary to fasten the individual bracket in place by two bolts. This saves labor. No. 160 Saddle Hangers-- Standard Type Fig. No. 169 GRINNELL . Saddle Hangers ' are unique inasmuch as the hanger bar is. of steel in stead ' of cast iron. This feature not only reduces the height of the hanger but also re duces its cost. Hex-nuts at bottom of rods support the hanger and allow liberal adjust ment. These Saddle Hangers are excep tionally strong and will not sag. Labor cost of installation is considerably less than with Branch Rolls and Rods. The Saddle Hanger is used in connection with in. rods andiiex-nuts on 2 to 8 branch hangers --Yg in. rods and hex-nuts on 9,to 12 branch hangers--and with Expansion Cases, Grin nell Hanger Flanges, or with Side I-Beam Clamps to steel work, for supporting overhead coils. 516 Grinnell Company, Inc.

No. 174 Adjustable Swivel Pipe Roll (Patented October 4,1921) r 11HE Adjustable Swivel Pipe Roll supplies the need for any ad justable type of pipe roll hanger with single hanger rod. It is unique inasmuch as vertical adjustment can be made by use of the Swivel Shank at the top of the hanger. As in the Swivel Pipe Ring, Fig. No. 101, the Swivel Shank automatically locks, preventing loosening due to vibration in the pipe line. Branch Pipe Rolls /^JRINNELL Pipe Rolls are especially designed to take care of expansion and con traction. The rolls are made hollow so that only a small surface is in contact with the rod whereas the surface in contact with the pipe is made as large as possible. This allows the roll to take care of expan sion and contraction properly. Through a specially designed socket, vertical adjustment is allowed at the bottom of each vertical rod as-well as at the Ceiling Flange. Furthermore, the nut at the bottom of the hanger rod fits into a recess of the socket preventing loosening or turning from vibra tion. Fig. No. 17B Fig. No..199 Adjustable Pipe Stand--Anchor Chair-- Pipe. Seat--used with Welded Steel ' No. 196 Bracket YIELDED Steel Bracket Fig. No. 199 is light in weight ' ' as compared with the usual cast iron brackets. It was designed primarily for use with the Grinnell Adjustable Pipe Stand Fig. No. 196, Anchor Chair Fig. No. 197 and Pipe Seat Fig. No. 198, here illustrated. These combine the strongest type of brackets and pipe sup ports procurable. The Adjustable Pipe Stand as used with the Steel Bracket has excellent adjustment features,, it being possible to obtain vertical adjustment by simply ad justing bolts on the roll stand. A lateral adjustment or movement is possible with the Adjustable Pipe Stand and Pipe Seat by sliding the Stand or Seat on the bracket. With the Anchor Chair, lateral adjustment is also possible if Chair is moved before the nuts on the anchor yoke are tightened. V Fig. No. 197 517 Fig. No. 198 s
