Description
G. W. NEWMAN BINDER BAR AND HINGE LUG THEREFOR Filed March 30, 1954 Patented May l9, 1936 PATENT OFFICE BINDER BAR AND HINGE LUG THEREFOR George W. Newman, St. Louis, Mo., assignor to Loose Leaf Metals Company, a corporation of Missouri Application March 30, 1934, Serial No. 718,111
4 Claims. (Cl. 129-12) The invention relates to binder bars for loose leaf binders of the post type, and to hinge lugs therefor. V
The objects of the invention are to provide a bar having apertures for engagement by the feet of a hinge lug, and a one-piece hinge lug havin integral feet adapted to enter such apertures and be clinched therewithin.
In the accompanying drawing showing the preferred form of the device and the manner of attaching the hinge lug to the bar,
Fig. 1 is a view in perspective of a pressure bar of a loose leaf binder equipped with the improved hinge lugs;
'15 Fig. 2 is a view in perspective of the lug and a portion of the bar, the parts being shown separately; and
Fig. 3 is a sectional view on the line 3--3 of Fig. l.
The binder bar I0 is of ordinary construction, being made of sheet metal folded to form a flattened tube, its side margins being brought into contact with each other but without being secured together except by means of the improved hinge lug. The hinge lug is formed of a piece of sheet metal approximately rectangular in shape, its middle portion being bent to form a tube l I, providing a hinge pin socket [2, the two side portions of the sheet being continued radially and in contact to form a shank portion l3 of suitable length, and then spread laterally, as at M, and then bent toward each other to form attaching feet 15, the intermediate portion of 35 the side margins of the plate being cut away.
To provide for the attachment of the hinge lug to the tubular bar ID, the latter is apertured, as shown at I6, to receive the feet l5. These apertures flare slightly at the inner face of the 40 tube wall, as shown at ll. The feet [5 having been inserted through the apertures l6, are bent toward-each other, as shown at I8, and by means of a suitable tool are compressed by a swaging action into the flaring inner ends ll of the apertures l6, filling them and fixedly securing the lug to the bar. The swaging operation tends to draw together the edges of the sheet of which the bar [0 is formed, and the two hinge lugs 5 stiffen and. strengthen the bar.
While the hinge lugs are shown as attached at the seam edge of the bar, they may, if desired, be attached at the closed edge, the stiffening and strengthening advantage referred to be- 1 ing sacrificed.
I claim as my invention 1. A hinge lug formed of a piece of sheet metal folded along a median line to form a pintle eye, the side portions of the sheet being extended radially and in juxtaposed relation to form a suitable shank, and then spread apart and rebent near their margins to form approximately parallel feet, the side margins of the sheet being notched to provide a plurality of feet.
2. In combination, a binder bar of sheet metal having the form of a flattened tube, the margins of the sheet meeting at one edge of the tube and 7 being slotted, the inner ends of the slots flaring, and a hinge lug formed of sheet metal and having integral feet projecting through the named slots and swaged to fill such slots.
3. In combination, a binder bar of sheet metal having the form of a flattened tube, the margins of the sheet meeting at one edge of the tube and being slotted, the inner ends of the slots flaring, and a hinge lug formed of sheet metal and having integral feet projecting through the named slots and having their inner ends bent toward the tube seam and being swaged to fill such slots.
4. In combination, a binder bar formed. of a sheet of metal bent to form a flattened tube having an open seam and companion apertures on opposite sides of the seam, and a one-piece hinge lug having feet projecting through the apertures and clinched against the inner face of the tube.
GEORGE W. NEWMAN.
