UNITED STATES PATENT OFFICE.

DANIEL W. HALLOCK, 0F ROCKY POINT, NEw YORK;

LOOSELEAF BINDER.

To all whom it may concern:

Be it known that I, DANIEL W. HALLOCK, of Rocky Point, in the county of Suffolk, in the State of New York, have invented new and useful Improvements in Loose-Leaf Binders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in loose leaf binders involving the use of flexibly connected side pieces, one of which is provided with a set of angular studs rigidly secured and projecting inwardly at substantially right angles thereto and adapted to pass through correspondingly formed apertures in the sheets which are to be bound between the side pieces. The free ends of the studs are provided with laterally swinging arms of substantially the same form as the cross sectional form of studs to which they are pivoted and adapted to swing laterally into and out of registration with said studs so that when registered the sheets may be readily placed upon and removed from the studs and when thrownout of registration they serve to hold the sheets against removal.

The invention also embodies means coacting with the swinging arms for holding them in their open or binding positions.

I am aware that it is common to provide flexibly connected side pieces with one or more studs of angular cross sect-ion adapted to pass through correspondingly formed apertures in the sheets but so far as I am aware it is customary to employ a sliding member for interlocking engagement with the free ends of the studs to hold the sheets thereon which requires considerable accuracy in fitting the parts for coaction in order that they may properly register one with the other in the operation of binding the loose sheets between the side pieces.

The main obj ect, therefore, of my present invention is to produce a loose leaf binder in which the studs which enter the apertures in the leaves are more effectively maintained in their proper relative positions with less liability of being accidentally bent or deflected and at the same time carry the means by which the sheets are held against removal from the studs.

Another object is to provide means for locking the sheet retaining members in their binding positions and at the same time operatively connecting the side pieces to hold Specification of Letters Patent.

them in fixed relation andpermit the covers 1 to be opened and closed in the usual manner for opening and closing the covers of books.

Other objects and uses will be brought out in the following description:-

In the drawingsFigure 1 is a top plan 1 of a portion of my improved loose leaf binder in position for retaining a series of loose leaves, one of the side pieces being removed to show the locking device. Fig. 2 is a perspective view of portions of the side pieces and their flexible connections sho-wstiffening bars 3 are incorporated in a flexible sheathing 4C forming a flexible back -5- connecting the side pieces. These side pieces form a part of and are flexibly connected by webs 6 to suitable covers 7 for receiving between them a series of loose leaves a-.

A pair or set of studs 8 of angular cross section and preferably of metal are rigidly secured at one end by riveting or otherwise to the side bar -1- and project inwardly at substantially right angles thereto and are adapted to be passed through correspondingly formed apertures in the sheets -afor retaining said sheets between the side pieces or between the covers 7.

Pivotally mounted upon the inner or free ends of the studs 8 are laterally swinging arms 9 of substantially the same form as the cross sectional form of their the adjacent portions of the sheets and there- 1 by hold them against endwise displacement from the studs. This manner of retaining the loose sheets in the binder allows the opposite cover to be thrown backwardly leav-- ing the entire area of the uppermost sheet exposed and permits the superposed leaves to be more easily raised for inspection of the reference matter on any one of the underlying leaves. It is customary, however, to provide means for locking the opposite side pieces of the covers together to form a book containing the loose leaves to be filed away and referred to whenever necessary and for this purpose I provide the side piece -2 with a pair or set of inwardly projecting studs -l0 and an additional or somewhat smaller set of studs -11-, all of which are rigidly secured by riveting or otherwise to the bar -2.

The studs -10- are relatively positioned so as to interlock with the rock arms 9 when the covers are folded one over the other and for this purpose are provided in one side with recesses 12 for receiving the free ends of the arms 9 as best seen in Figs. 1 and 4, said arms being held in interlocking engagement with the studs -10 by means of a spring rod or bar -13 also shown in Fig. 1 as having its intermediate portions resting against the front faces of the arms 9 and its ends engaged in recesses --1lin the rear sides of the studs --11.

The rod or bar l3- is of slightly greater length than the distance between the studs 11- and is adapted to be placed in operative position and removed by hand, its primary function being to hold the locking members 9 in interlocking engagement in the recesses 12 of the studs 10, thereby holding these portions of the covers in fixed relation to each other and permitting the main bodies of the covers to be rocked backwardly on the flexing connections 6 for inspection of the reference matter on the loose sheets.

The studs -8 and apertures ain the sheets for receiving said studs are elongated in rearwardly converging lines as best seen in Fig. 1 and are somewhat tapering or wedge-shape, thus permitting the sheets to be interchanged or reversed either side up with the assurance that their apertures will register with the studs 8-. v

The laterally swinging locking members or arms 9- are of the same form in top plan as the cross sectional form of the studs 8 of which they form a part and when placing the sheets upon or removing them from the studs, these rock arms are adjusted to coincide with the main bodies of the studs but in binding the sheets between the covers, they are rocked laterally to the position shown in the drawings so as to extend laterally some distance beyond or outwardly from the main bodies of the studs and their corresponding openings in the sheets. The adjacent cover -7 is then folded over substantially parallel with the opposite cover to bring the studs -l0- into interlocking engagement with the laterally projecting portions of the arms --9 which enter the recesses 12. The locking bar or rod 13 is then placed against the front faces of the arms 9 and its opposite ends are sprung in behind the studs -ll so as to enter the recesses l l therein, thereby holding the arms -9 in interlocking engagement with the studs 10 and also holding the rear portions of the covers in fixed relation to each other.

\Vhen it is desired to remove or replace any of the loose sheets, it is simply necessary to withdraw the bar -13- endwise until disengaged from the studs 11, whereupon the arms 9 may be rocked out of engagement with the studs 10, thus permitting the adjacent cover to be thrown backwardly upon its flexing connection 5- leaving the inner sheets and studs 8- exposed so that the arms 9 may be moved into registration with said studs to permit the removal or replacement of the sheets.

hat I claim is:

1. In a loose-leaf binder, opposite side pieces and flexing connections between them, studs secured to and projecting at substantially right angles from one of the side pieces and provided at their free ends with laterally swinging arms pivoted thereto and movable into and out of registration therewith.

2. In a loose-leaf binder, opposite side pieces and flexing connections between them, studs of angular cross section secured to and projecting inwardly from one of the side pieces and having their outer ends provided with laterally swinging arms of substantially the same cross sectional form as their respective studs and pivoted thereto.

3. In a loose-leaf binder, opposite side pieces flexibly connected to each other, studs rigidly secured to and projecting at substantially right angles from one of the side pieces and provided with laterally swinging sections forming locking arms, additional studs on the opposite side piece having recesses for receiving the free ends of said arms for locking the last named side piece to the first named studs.

4. In a loose-leaf binder, opposite side pieces flexibly connected to each other, studs rigidly secured to and projecting at substantially right angles from one of the side pieces and provided with laterally swinging sections forming locking arms, additional studs on the opposite side piece having recesses for receiving the free ends of said arms for locking the last named side piece to the first named studs, and means for holding the arms in the recesses.

5. In a loose-leaf binder, opposite side pieces flexibly connected to each other, studs rigidly secured to and projecting at substantially right angles from one of the side pieces and provided with laterally swinging sections forming looking arms, studs on the opposite side piece having recesses for receiving the free ends of said arms for locking the last named side piece to the first named studs, additional studs on the second named side piece, and a locking bar having its ends engaged with the rear faces of the additional studs and its intermediate portion engaged with arms to hold the latter in locking engagement with the second named studs.

In witness whereof I have hereunto set my hand on this third day of May 1911.

DANIEL W. HALLOCK.
