United States Patent PRESS FOR CLOSING THE RINGS 0F MECHANICAL BINDINGS Arthur F. Brook, Poughkeepsie, N. Y., assignor to Wire-0 Corporation, Poughkeepsie, N. Y., a corporation of New York Application September 16, 1953, Serial No. 380,437 1 Claim. (Cl. 140--93) The invention disclosed in this patent application is a press for closing the rings of mechanical bindings. These rings, after the perforated sheets have been engaged thereon, are of open C-shaped formation.

The present invention provides a means for closing the open C-shaped rings to substantially circular formation.

Particular objects of the invention are to provide a machine for the purpose which will be of a light, portable nature adapted to be used in an ofiice or like place where it might be desired from time to time to bind together sheets of records, reports or the like.

Special objects of the invention are to provide such a press in a simple mechanical structure, easily understood and readily operable without previous training or experience.

Further special objects are to provide a machine of the character indicated which may be quickly and easily adjusted to close the bindings to exactly circular ring formation and to adapt the machine to different size bindings.

Other desirable objects attained by the invention and the novel features of construction, combination and relation of parts constituting the invention are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part of the specification illustrate a present commercial embodiment of the invention. Structure, however, may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

Fig. 1 in the drawings is a top plan view of the machine in the open position, the operating handle shown broken away;

Fig. 2 is a front elevation;

Fig. 3 is an enlarged broken vertical sectional view on substantially the plane of line 3-3 of Fig. 1, and showing a mechanical binding in position for the ring closing operation;

Fig. 4 is a similar view showing the closing bar lowered and the rings closed to circular formation;

Fig. 5 is a broken vertical sectional view on substantially the plane of line 5-5 of Fig. 1, illustrating the closing bar adjustment means;

Fig. 6 is a broken horizontal sectional detail on substantially the plane of line 6-6 of Fig. 5;

Figs. 7 and 8 are broken detail views of the mechanical binding as it appears on opposite sides.

The base of the machine is shown in the form of a single casting having a bottom rest or support 10 for the binding 11 and sheets 12 and an upright gage or backstop 13 for positioning the open sides of the rings, as in Fig. 3.

A ring closing bar 14 is mounted to operate vertically over the face of the back gage, it being shown as slidingly confined at opposite ends in guideways 15 provided by the Lshaped cross section angle piece-s 16 secured by screws 17 over the face of the post extensions 18 at the opposite ends of the back gage.

The closing bar is raised "and lowered by a rock shaft 19 operating as an eccentric roller through the medium of eccentrically disposed pins or pintles 20 journaled in bearing blocks 21.

2,781,797 Patented F eb. 19, 1957 ice Hook shaped hangers 22 extending from the back of the closing bar up over the top of the roll shaft, confine the bar to the shaft so that it will be raised as well as lowered by rocking action of this eccentrically journaled shaft.

For purposes of adjustment the bearing blocks 21 are shown slidably disposed in the upper ends of the guideways 15 and as shifta-ble up or down through the medium of thumb-screws 23 engaged in the tops of the posts 18 and having extended fiat heads 24 entered in notches 25 in the backs of the blocks.

This construction provides quick, easy, independent up and down adjustment of the bearing blocks at opposite ends of the bar, enabling an operator to effect quick and accurate adjustment at either or both ends of the *bar, as may be required to fully open the machine to freely receive the bindings and to fully close the rings from the open C-shape shown in Fig. 3 to the substantially circular formation shown in Fig. 4.

These adjustments of the bearing blocks also provide for operating on different size bindings.

To assist in setting the machine for different size bindings, suitable gage marks may be provided on the front of the bearing blocks to register with the tops of the posts, substantially as indicated at 25, Fig. 2.

Suitable means are provided for rocking the eccentric roller shaft 19, such as an angularly projecting hand lever 27 engaged with the intermediate portion of the shaft.

The machine consists of but few parts, and these all of simple, rugged construction. Necessary adjustments are easily effected and the ring closing operation is simple and direct, it only being necessary to insert the sheets with the open side of the binder rings against the backstop, as shown in Fig. 3, and then to rock the handle forward so as to lower the closing bar far enough, as shown in Fig. 4, to transform the rings from the open C-formation to the circular shape shown in Fig. 4.

While particularly suited to closing the rings of the double strand wire bindings shown in Figs. 7 and 8, it will be clear that the invention may be used for operating on other forms of mechanical bindings.

I claim:

A press for closing the rings of mechanical bindings, comprising a base for supporting the bindings, said base having a back gage for positioning the bindings and upstanding posts at opposite ends of said gage, L-shaped angle bars secured over the front of said posts and forming with the front of said posts vertical guideways at the sides of the posts, bearing block's slidably engaged in the upper ends of said guideways, screws mounted in the posts and engaging said bearing blocks to eifect vertical adjustments of the same, an eccentric roll shaft having eccentrically disposed pins in opposite ends of the same journaled in said bearing blocks, an angularly projecting handle engaged with the intermediate portion of said shaft for rocking the same, a closing bar slidably engaged in the lower portions of said guideways and hang ers extending from said closing bar up over the top of said eccentric roll shaft and loosely confining said bar to the shaft.
