' TRANSFER-FILE.

SPECIIEIUATION forming part of Letters Patent No. 720,975, dated February 1'7, 1903. Application filed November 25, 1901. fierial No. 83,669. (lilo model.)

To all whom 1 itm-cty concern:

Be it known that I, LABS G. SGHULT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

5 have invented certain new and useful Improvements in Transfer-Files, of which the following is a specification.

The object of this invention is to produce a transfer-file embodying the novel features hereinafter more fully shown and described.

In the accompanying drawings, Figure l is a perspective view of atransfer-file separated for the removal of some of its leaves. Fig. 2 is a longitudinal section showing the binder r5 mechanism. Fig. 3 is a transverse section showing the locking mechanism for the filecover. Fig. 4 is a top plan view of the binder mechanism, showing the means for, securing the top member thereof in position.

Like letters of reference indicate corresponding parts throughout the several views,

prongs of the opposite side bar of the binder,

to be next described.

O is the opposite side bar of the binder device, having the prongs O fixed thereto, as by riveting. plate 0 pivoted by the stud C upon its outer face andlying in close contact there- 0 with. At one end the plate 0 carries the stud O fixed to said plate, and at its opposite end has an elongated opening'C' through which the stud C secured rigidly to the side bar 0, projects. A straight spring 0 extends from the stud 0 around the pivotal stud G its outer end lying in contact with the stud C. Openings C for the reception of the prongs B extending through the side bar 0 and through the pivotal plate C at opposite sides of the center of the former, are

This bar is provided with arespectively coincident in the side bar 0 and the pivotal plate C when said plate is moved against the action of its spring 0 When the prongs B are placed in the openings C and the ends of the prongs G in the openings B in the side bar B, the spring-plate C is pushed aside against the action of the spring 0 and the prongs 13 enter their openings in the side bar 0. As soon as said prongs project through said plate the pivbe otal plate 0 by reason of its spring action engages the notches B in the upper ends of the prongs B.

A keeper D, somewhat of L shape, and therefore having the arms D and D is se- 6: cured, with the arm D in contact with the flexible connection A between the covers A and A. The other arm D of this keeper is provided with an opening D and the position of the keeper is such with relation to the holder mechanism that the opening D is adapted to engage with the upper end of the stud G upon which the pivotal plate 0 turns. 7 When the file is closed, the keeper is in engagement with said stud and holds the file firmly together. When it is desirable to open the file, the keeper D is raised from engagement with the stud G by the thumb of the operator and the cover A laid back from the holder mechanism. The spring-plate is So then turned upon its pivotal stud C and the side bar 0 removed. This leaves the binder in the position illustrated in Fig. 1, in which position the make-up of its contents may be changed. When the arrangement is complots, the sidebar 0 is put in place, the back A? brought up into its proper position, and the keeper D snapped over the top of the pivotal stud C It is clear that many slight changes may be made in the construction of this file without departing from the spirit and scope of my invention. Henceldesiretohaveitunderstood that I do not limit myself to the precise details of the embodiment herein shown and de- 5 scribed.

I claim as my invention- 1. In a file, in combination, a hinged cover; a binder device comprising a side fixed to said cover, and a removable side, each of said IOU sides being provided with holding-prongs; and a keeper secured to said cover, adapted to engage with said removableside.

2. In a file, in combination, a hinged cover; a binder device comprising a side fixed to said cover and provided with prongs, a removable side also provided With prongs, said removable side having openings therein for receiving the ends of the prongs of said fixed side, and means on said removable side for holding said side in releasable engagement with the prongs of said fixed side; and a keeper secured to said cover, adapted to engage with a portion of said binder device.

3. In a file, in combination, a hinged cover; a binder device comprising a side fixed to said cover and provided with prongs having notchesin their outer ends, a removable side also provided with prongs, said removable side having openings therein for receiving the outer ends of the prongs of said fixed side, and a pivoted plate on said removable side, adapted to engage the notched ends of the prongs of said fixed side, to hold said removable side in releasable engagement with the prongs of said fixed side; and a keeper secured to said cover, adapted to engage with a portion of said binder device.

4. In a file, in combination, a hinged cover;

a binder device comprising a side fixed to said cover and provided with prongs having notches in their outer ends, a removable side also provided with prongs, said removable side having openings therein for receiving the outer ends of the prongs of said fixed side, a pivoted plate on said removable side, and a spring adapted to hold said pivoted plate in releasable engagement with the notched ends of the prongs of said fixed bar; and a keeper secu red to said cover, adapted to engage with a portion of said binder device.

5. In a binder, in combination, a side bar provided with prongs; a second side bar having openings therein for'receiving the ends of the prongs of said first-mentioned bar, said second side bar also being provided with prongs; and means on said second side bar for holding said bar in releasable engagement with the prongs of said first-mentioned side bar.

6. In a binder, in combination, a side bar provided with prongs having notches in their outer ends; a second side bar having openings therein for receiving the outer ends of the prongs of said first-mentioned bar, said side bar also being provided with prongs; and a pivoted plate on said second bar adapted to engage the notched ends of the prongs of said first-mentioned bar, to hold said second bar in releasable engagement with said prongs.

7. In a binder, in combination, a side bar provided with prongs having notches in their outer ends; a second side bar having openings therein for receiving the outer ends of the prongs of said first-mentioned bar, said side bar also being provided with prongs; a pivoted plate on said second bar; and a spring adapted to'hold said pivot-ed plate in releas able engagement with the notched ends of the prongs of said first-mentioned bar.
