underside of the top. It is insulated with <strong>on</strong>e inch of pressed pure <strong>cork</strong>-<br />

board, and a nickel silver bottom, binding the entire cover together, is<br />

sprung into a groove in the n<strong>on</strong>-c<strong>on</strong>ductor frame. The fr<strong>on</strong>t and rear<br />

half are each provided with rubber tipped knobs, doing away with the old<br />

thumb nip, thus eliminating the slight opening, and providing additi<strong>on</strong>al<br />

precauti<strong>on</strong> against refrigerati<strong>on</strong> loss, at the same time making the operati<strong>on</strong><br />

of these covers easy and noiseless. The illustrati<strong>on</strong> shows clearly that all<br />

metal to metal c<strong>on</strong>tact is broken practically eliminating all refrigerati<strong>on</strong><br />

loss.<br />

FIG. 197.—INSULATED SYRUP UNIT.<br />

Syrup Unit.<br />

Frame.—The usual unbeatable Louisiana red cypress is used in the<br />

c<strong>on</strong>structi<strong>on</strong> of the syrup unit frame. The bottom is 5-ply, ^-inch Haske-<br />

lite panel board, which gives the necessary strength to insure that quality<br />

of endurance.<br />

N<strong>on</strong>-C<strong>on</strong>ductor.—Wherever it has been necessary Guaranty soda<br />

fountains are equipped with special n<strong>on</strong>-c<strong>on</strong>ductor to practically eliminate<br />

all refrigerati<strong>on</strong> loss. The syrup unit is so c<strong>on</strong>structed, and special n<strong>on</strong>-<br />

c<strong>on</strong>ductor strips, <str<strong>on</strong>g>complete</str<strong>on</strong>g>ly breaking all metal-to-metal c<strong>on</strong>tact with the<br />

outside, are provided in the c<strong>on</strong>.slructi<strong>on</strong>, as shown by the accompanying<br />

illustrati<strong>on</strong>.<br />

Drain for Draft Arm Spillage.—All Guaranty interiors are c<strong>on</strong>structed<br />

with an open drain, leading from the drip pan to the creamer outlet. This<br />

is attached to the rear syrup unit wall, a c<strong>on</strong>venient and out of the way<br />

locati<strong>on</strong>. No spillage resulting from mixing drinks at draft arms reaches<br />

the syrup jar enclosure bottom, making it easy to keep dry and clean.<br />

Lining.— 16-ounce pure cold rolled tinned copper forms the lining,<br />

made of <strong>on</strong>e piece with ends double seamed and soldered.<br />

Capping.—The fr<strong>on</strong>t rail and top capping are heavy Grade A 18%<br />

nickel silver.
