THE SUPPLY SECTION includes all supplies except storage batteries, other power equipment, and protection and cross-connecting equipment. This equipment is shown under "Power" in the Apparatus Section. THE PIECE PART SECTION includes piece parts which are regularly supplied and which can be replaced by operating companies. HOW TO ORDER All orders should include both the code number and the name of the article or product ordered. In general, both the code number and the name are necessary to properly identify the apparatus. Piece parts should be ordered by piece part number. Where itemized drawings are shown in the Piece Part Section the associated code number should be determined from the accompanying listing of piece part numbers. TCI Library: www.telephonecollectors.info CUSTOMER INFORMATION Guarantee Goods properly used are fully guaranteed for one year against any defect in material or workmanship and are subject to replacement. Always notify a Kellogg office before making any return shipments. This will help to make the proper adjustment without delay. Terms All invoices to companies whose credit has been approved are payable net, within 30 days from date thereof, except those covering some items of construction material which carry a discount for cash within 10 days from date of invoice or those whose terms were specified in quotations, proposals or contracts. We invite the opening of charge accounts. New customers who ordinarily are not rated by commercial agencies can help assure prompt service by sending in credit information such as their latest balance sheet and profit and loss statement, bank or other references, with initial orders. Sight draft or C.O.D. orders receive the same attention as those covered by established charge accounts. Orders To avoid errors or delays, catalog numbers as well as the name of each article should appear on the order. Possibilities of delay are decreased when complete information is given in the order. Telephone or telegraph orders should be confirmed by mail immediately so that if a mistake is made in transmission of the order it can be checked and corrected. However, confirming orders should be marked "Confirming" to avoid the possibility of duplication. Changes and Cancellations A reasonable charge is made for changes or cancellation of orders when engineering, special assembly or adjustment is involved. These charges are only sufficient to compensate for the actual loss in time or material. Shipments Always specify whether goods are to be shipped via freight, express or parcel post. When shipment is desired by freight specify the routing. In the absence of instructions Kellogg will select routes which will assure the best service. Claims for Shortage, Breakage or Non-Delivery All claims for breakage, damages and non-delivery should be made at once to the transportation company handling the shipment. Kellogg will gladly assist in presenting these claims. Receipts from the transportation company specify that shipments are received in good condition, therefore shipments must be checked as they are received. Always have the agent of the transportation company make a notation on the bill of lading specifying any damage or shortage. If packages or cases are in apparent good order, but contents are found to be damaged upon opening, call the freight agent or adjuster and have him mark the freight bill to show the concealed damage. Claims for damage or non-delivery of parcel post shipments should be made to Kellogg as Kellogg insures this material and makes all adjustments. Returning Goods Please notify Kellogg before making any return shipments. This will help to make the proper adjustment without delay. The liability of the Kellogg Company is limited in all cases to the value of the goods claimed to be defective. Marine or Parcel Post Insurance Unless otherwise directed, Kellogg will insure against non-delivery all shipments made by steamer or parcel post. A charge will b&! made to cover this cost.

KELLOGG SWITCHBOARD AND SUPPLY COMPANY-CHICAGO TCI Library: www.telephonecollectors.info 7 C Cable APPARATUS SECTION BRAID AND LEAD COVERED CABLE Kellogg switchboard cable is manufactured from the best grades of selected raw materials by specially designed machinery and is furnished in several types and sizes. The copper conductors are either tinned or tinned and enameled, depending upon the type of cable. All conductors, except rubber covered conductors used on certain power cable, are insulated with two servings of cellulose acetate yarn followed by a cotton wrap or braid. The twisted pairs are formed into a cable, covered with several wraps of insulating paper, and impregnated with a special high grade moisture proofing wax compound. Available in round or flat types. On braid covered cable the standard over-all covering is braided cotton, saturated with a grey flameproof paint. For all types of cable the over-all covering is listed with other descriptive matter in the charts shown below. A standard color code is used in Kellogg cable so each pair of conductors can be identified. With the code number of each cable is listed a reference to the color code for that cable. The color coding of any cable can thus be determined by referring to the color scheme charts. Short lengths of cable will be shipped in boxes. Longer lengths will be shipped on suitable reels. When reels are furnished they will be charged for. Full credit will be allowed for their return, in good condition, prepaid to the Kellogg factory.
