CARD-FILE.

SPECIFICATION forming part of Letters Patent No. 580,632, dated April 13, 1897. Application filed February 3, 1896. Serial No. 577,815. (No model.)

To all whom it may concern.-

Be it known that I, HENRY C.YEISER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Card-Files, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates, primarily, to files for index-cards for use in libraries, offices, and other places where cards are used for purposes of indexing or reference; and it has for its object the improved construction of such files whereby their case of manipulation, security, and efficiency are increased.

The novelty of my invention will be herei inafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a card-file embodying my invention and partly filled with cards. Fig. 2 isalongitudinal central sectional view of Fig. 1 in side elevation. Fig. 3 is a transverse sectional view in detail on the dotted line 00 w of Fig. 1. Fig. 4 is an enlarged elevation in detail of the lock mechanism for the filing-rod. Fig. 5 is an enlarged sectional detail of the follower-support and associated parts. Fig. 6 is an enlarged inside elevation of the spring mechanism for the filing-rod.

The same letters of reference are used to indicate identical parts in all the figures.

In its preferred form of construction the file is a drawer with bottom A, side walls B, and front and rear walls C and D, respectively. The interior width of these drawers, which are fitted and slide in a protecting case or cabinet made for the purpose, is just su fficient to receive the cards E, which stand on edge transversely of the drawer and are separated by other higher cards F, having numerals, letters, or other index matter on their projecting ends to properly space and classify the cards E. All of the cards are normally held in place in the drawer by a filing-rod G, extending through perforations near the bottom of the cards and through the front wall C of the drawer, where its projecting end is provided with an operating button or thumbpiece a. When the filing-rod is pushed entirely in, its rear end is confined in any suitable bearing-socket b in the rear wall D, as seen in Fig. 2. On the front wall C is a springcasing H, Figs. 2 and 6, with an elongated aperture 0 for thepassage of a flattened portion of the rod with exterior shoulders, which, when the rod is pushed entirely in, is partially turned by the action of the springs e to bring said shoulders against theinner wall of the casing H to hold the rod locked against accidental withdrawal, substantially as in prior patent to Dom, No. 525,947, of September 11, 1894. However, to hold the rod enti rely locked, so that no one but the custodian of the drawer can withdraw it, I provide in the front wall of the drawer a look I, Figs. 2 and 4, having a removable key f, which actuatesa bolt g, having a slot h in its end, which, when projected, straddles the rod G in a circumferential groove 2 in the same, and secu rely holds the rod from withdrawal, as will be readily understood. Upon withdrawing the bolt by turning the key the rod can be partially turned and withdrawn in the usual manner for the purpose of removing cards or inserting new ones.

The lock maybe of any well-known or suitable construction, and the only essential to this feature of my invention is that its bolt shall engage the filing-rod when properly inserted in such manner as to prevent the withdrawal of the latter.

The remaining feature of my invention relates to the card-follower for holding the cards upright and compressed in the case. The follower is a block J, preferably wedge-shaped and fitted transversely within the drawer and having a slightly-enlarged aperture through which the filing-rod G passes, said enlarged aperture allowin the block J to have aslight vertical or rocking movement on the rod G to permit the shifting of said block or follower to its various positions. Its bottom edge rests on the bottom of the drawer, as shown, and it has secured upon its rear face a metal strip j, whose lower end extends down into a slot is in the bottom of the drawer, which slot is preferably directly under the filing-rod and extends the whole length of the drawer. In this slot is a rod K parallel to the rod G and whose ends are permanently secured to the front and rear ends of the drawer in any suitable manner. This rod K passes snugly through a perforation Z in a downward extension of the strip j, and a spring m, Fig. 3, of any suitable construction, carried by the follower at a point somewhat removed from the strip j, bears against the bottom A in such manner as to tip the follower sufiiciently to cause the edges of the perforation Z to bind or pinch upon the rod K sufficiently to lock the follower in any of its adjusted positions. To move the follower either forward or back, it is only necessary to press it down, as shown by the solid lines, Fig. 5, when the spring in will be compressed and the edges of the perforationl will cease to bind 0n the rod K, thus permitting the follower to be slid back or forward on the filing-rod to any point desired, when, upon removing the pressure, the s rin will tip the follower and cause it to be locked to the rod K, as will be readily understood. It is to be observed that while the follower is normally locked to the rod K it is never'locked to the filing-rod G, and that the latter can be withdrawn or inserted without unlocking the follower from the rod K.

Having thus fully described my invention, I claim 1. In a card-file, the combination of the longitudinally-removable filing-rod, a follower free to slide thereon and having a limited vertical movement on said filing-rod, a second rod parallel with the filing-rod and engaged by a perforated lug or projection on the follower, whereby the latter when tipped is gripped to said last-named rod,.substantially as described.

2. In a card-file, the combination of the longitudinally-removable filing-rod, a follower free to slide thereon, a second rod parallel with the filing-rod and confined in a slot in the base of the file, a perforated lug carried by the follower and embracing the second rod, and a spring carried by the follower and bearing against the base of the file, whereby the follower is held normally locked to the second rod in any of its adjusted posit-ions, substantially as described.
