LOOSE-LINE sYs'rEM.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed August 30, 1915. Serial No. 47,948.

T 0 all whom it may concern:

Be it known that I, CHARLES P. FERRERO, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Loose-Line Systems, of which the following is a specification.

The object of my invention is to provide a system of keeping posted a mass of constantly changing data, which will be simple, cheap to manufacture, and quickly and easily operated to locate any of the data therein; possessing both the advantages of visibility, that is, presenting its reading matter to view at all times without handling the separate cards of which it is composed, and elasticity, that is, removable and adjustable in its separate parts to receive new and additional cards or to permit obsolete ones to be withdrawn.

In carrying out this object, I employ a shallow tray or holder to contain a plurality of cards arranged on their lateral edges, each of said cards being thick enough at its exposed face to receive writing, and received in the base of the tray, with its upper edge projecting above the sides thereof to permit ready access for removal, and held in place by a marginal cover carried by said tray; and a container or cabinet to receive a plurality of such trays.

One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawing. in which Figure 1 shows a front elevation of the assembled device.

Fig. 2 shows a plan view of one of the trays.

Fig. 3 is a longitudinal, vertical, sectional view of the tray.

Referring in detail to the form of my invention illustrated in the drawing, it will be seen to comprise a shallow tray or holder A, provided with a bottom 10 and sides 11, and hinged to the back of one of said sides is a cover frame B formed of downwardly projecting sides 12 and marginal upper; sides 13.

In the tray is arranged a cards 0, each of elongated rectangular shape, formed of a body portion 14 of tar, straw=board, wood, or other suitable material, covered over by a strip of thin writ plurality of ing paper 15, or coated with other suitable material. The thickness of thecards is preferably approximately that of a single line space; These cards are stood 1 on their lateral edges and completely fill the tray, with their upper portions projecting above the sides thereof so that an operator desiring to remove any individual card may do so without disturbing the others merely by engaging it with his fingers at the upper end corners. When the cover frame is down, its sides 12 inclose the projecting portions of the cards and overlap the sides of the tray.

A cabinet 16 is preferably provided, and has a number of spaces 17, each of a size to slidably receive a tray A. A device 18 is provided for each tray for pulling the same out of the cabinet.

In practical use, I find my new loose line system to be particularly suited for keeping a record of constantly changing data, such as is found in the real estate business. Therefore, as shown, I provide a heading 19, consisting of some such matter as List of city real estate for sale printed upon the edge of the upper card. Immediately beneath this is a card bearing column headlines 20, such as Kind of property, No. of rooms, Size of lot, etc., and below the head-lines all of the cards are ruled to agree with such heading, so that the whole gives the effect of a ruled ledger or journal page, with each item in its own column. Then when a certain property so listed is disposed of, the operator merely removes the card representing the same, sliding the others up to close the space, and inserting elsewhere a blank or newly filled out card to maintain the tray filled. \Vith all cards in position and filling the tray, the operator may easily write the desired date on any one of the cards, the face of such cards being preferably equal to the thickness of a typewritten line. When one side of a card has been used and the information thereon becomes obsolete, it may be reversed and its opposite side used.

For other uses than that already mentioned, it might be desirable to form the e cards of increased depth, utilizing the space at the sides thereof for detailed information, while the top or upper edge would constitute an index of what the card contained on its side. Thus in an account system, in looking for certain memo.-,- the top surface will disclose it at a glance Without the necessity of fingering the cards.

Other forms and uses of my card system may be employed Without departing from the spirit of my invention as disclosed in the appended claim.

Having thus described my invention, What I claim and desire to secure by Letters Patent is A card bookkeepi11g system including a tray, a series of cards in said tray set on edge therein, the top and bottom edges of the cards being of a thickness substantially equal to the Width of a line of typewriting,

the card at the top of the tray adapted to receive data indicating the tray contents, a cover frame fitted over the tray and comprising side members, and right angled upper flanges formed to engage over the ends of the upper edges of the cards to hold the same in position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
