In making requisitions upon the Purchasing Agent, the Storekeeper must take into consideration the length of time necessary to obtain the article wanted. Wire nails, wood screws, and such articles can usually be obtained in 24 hours, while brass tubing may take three weeks. Iron castings can be had in two days, while steel castings will frequently require six weeks.
When articles are received in stores, the date and quantity will be entered under the heading Received, and other quantities added to these as received. Articles issued will be charged under the heading Issued, giving the date and amount. The quantity on hand may be quickly ascertained by adding the quantities received and the quantities issued, and subtracting the sum of the issues from the sum of the receipts.
Fig. 24. Form of Invoice.
Entries are made by means of carbon paper, duplicating those made on the Requisition form, Fig. 23.
As most articles are purchased in considerable quantities and issued in small lots, there will be few entries of receipts and a large number of entries of issues; therefore the greater portion of the card is devoted to records of issues. The card is printed with the same form on both sides; and when the spaces on the first side are filled, the account is balanced, and the results carried to the opposite side.
These cards are kept in filing drawers, where they are located in alphabetical order by the names of the articles they represent.
A foreman, on receipt of a regularly numbered and authorized production order or sub-production order, is thereby authorized to make requisition for such stock and material as may be necessary to use in the execution of the order. This he will do by the use of the Requisition shown in Fig. 23, entering the order number and date, and specifying the quantities and descriptions of the articles required. Ordinarily each requisition will contain but one article or class of articles. At the bottom of the requisition, the foreman will enter the name of his department and his own signature.
These requisition blanks are made up in pads (the form shown in Fig. 23), of white paper alternating with tinted paper on which is the Invoice form shown in Fig. 24. This latter form has its ruling and other principal features identical with the form of the requisition, so that by the use of carbon paper the foreman makes a duplicate on the Invoice blank, of the order number and date, the articles required, the name of his department, and his own signature.
