STATIONERY ATTACHMENT.

Application filed January 6.1921. Serial No; 435,414.

I 0 all whom it may concern:

Be it known that I, EDGAR lV. Ur'ro, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Stationery Attaclnnent, of Which the following is a specification.

This invention relates to devices for binding or holding looseleat books or folders.

One of the objects of this invention is to provide paper fastening or holding members which can be actuated for the opening or closing operations by positive movements.

inother object is to provide an actuating member which by certain movements will cause and produce certain and positive actions and movements of the paper holding members.

Another object is to provide a suitable number of paper holding and fastening members disposed. "for tilting movements in the back of a folder, and having an actuating member in positive engagement With the holding and fastening members so that by a movement of the actuating member in one direction the fastening and holding members are opened While by a movement of the actuating member in the opposite direction the same holding and fastening members are closed.

Other objects will appear from the following description. and appended claims as well as from the accompanying drawing in 'which Fig. 1. is a general cross section through a folder with my device in proper position.

Fig. 2 is a fragmentary detail plan view of the actuating member seen from the underside.

Fig 3 is View of the a fragmentary detail edgewise actuating member.

Fig. l is a fragmentary detail top plan "view ol. a paper-fastening and holding member.

Fig. 5 is a fragmentary detail underside plan view oil? the end portion of the actuating member.

6 is an edgewise view of the illustrated portion in Fig. 5.

l ig. 7 is a cross section through the 210- tuating member on line 7'. of Fig. 2.

Fig. 8 is a cross section through the actuating member on line 8-8 of Fig. 2.

Fig. 9 is a cross section through the actual;- ing member on line 9-9 oi Fig. 2.

Fig. 10 is a cross section through the incasing bars or members in slightly modified form.

The numerals 11, 12 and 13, in Fig. 1, designate the several members of a folder or book all parts being considered edge or endwise. The plate or bar let is normally secured tothe folder or book, forming the base of the fastening or holding device. In the particular construction of Fig. l, the base member is provided With rolled-in edges 15, but it Will easily be understood that this may be varied without material ditl erence in the Whole device. In Fig. 10, for instance a slightly modified form of a base is illustrated, in which the base member 16 is provided with the rolled-in edges 17 reaching over the Whole edges of the cover plate 18. The cover plate 19, on the other hand, is provided with an extra ridge 20, rolled over outwardly, as illustrated in Fl x 1, to engage Withthe proportionally small rolled-in edge 15 of the base plate 1%. From this it will easily be understood that the cover plate 11) may be rolled in or out or otherwise shaped to engage with the base plate 1.4:, no matter how accomplished, as long as the cover plate ll) can be engaged with the base plate fl-fl. The cover plate 19 is preferably rolled in as indicated at 21, to form the bearing "for portions of the paperfastening and holding members. The portions 22 of the paper fastening and holding member, illustrated in Fig. at, are normally engaged Within the rolled-in edge 21. lhe actuating member 23 is provided with bent edges 24, as indicated in Figs. 2, 3, 7 and 9. The actuating member 23 is so disposed within the space between the base plate 1d and the cover plate 19 that the portions oi the several paper-fastening and holding members become located between the bent edges 24. of the actuating member 28 and the rolled-in edges 21 of the cover plate 1!), as best illustrated in Fig. 1.

Each paper-fastening member is provided on one or both ends with a jaw-like member 25, extending through the cover plate 19 so that opposite members meet when so disposed in the device, that is in their closed position as indicated in dotted lines at Each paper-fastening and holding member is furthermore provided with at least one bent portion 27, extending centrally between the cover plate 19 and the base plate 14, this bent portion being the actuating lever of the paper-fastening and holding members. In opened position, this lever 27 is in its uppermost position close to the cover plate, as illustrated in Fig. 1.

The actuating member 23 is provided with cut-outs and suitably shaped surfaces and portions to engage a suitable number of such levers 27 of the paper-fastening and holding members for operating and actuating the levers 27 so as to cause an opening or closing of the paper-fastening and holding members in a positive and certain manner. The bent edges 24; are cut out for suitable portions, as indicated at 28 in Fig. 3. The lips 29, see Figs. 2 and 3 are provided to engage under the lever portion 27 for holding the paper-fastening and holding members in open position, as also illustrated in Fig. l. IVhen the actuating member is shifted in the direction of the arrow 30, in Fig. 3, the lever 27 naturally comes to a position, indicated at 31 in Fig. 2. The front edges 32 of the lips are shaped to a rather sharp point. The opposite approaching edges 38 are also shaped to a rather sharp point, but arranged in alignment with the front edges ofthe bent edges 24, while the edges 32 are practically near the back of the U-shaped actuating member. This actuating member can in this form. preferably be made of sheet metal and pressed so as to form the edges 32 in the back while other portions of the-back of the U-shaped member are pressed through to come into alignment with the front edges of the bent edges 24L. The actl'lating member is inserted into the device so that the back 34 comes to rest on the base plate 1 1, while the bent edges project upwardly. To reduce the friction between the actuating member and the base plate, an impression is made in the back of the member 23 at a point close to the lips 29 to form the point 35 so that only this small point really rests on the base plate 14; at the very point where the lips are to press the levers 27 against the cover plate 19 to hold the paper-fastening and holding members in open position. The pressed portions 36 naturally tend to engage the levers 27 for closing the paper-fastening and holding, members, as will especially be understood from the illustrations in F 2 and 3. While the lips 25) are to engage under the levers 27, the portions 36 are naturally to engage over the levers 26 when so shifted, comparing the Figs. 1, 2, 3, 7 and 8.

Providing the actuating member 23 with a suitable number of such cutouts 2S and 31, and with a corresponding number of lips 29 and counteracting portions 36, means naturally that a corresponding number of paperi'iastening and holding members may be used in one device of this type. Such actuating member with the corresponding number of paper-fastening and holding members are then disposed in a common cover plate 19, and the cover plate is engaged to the base plate wherever used, so that only the front hook-shaped end 37, see Figs. 5 and 6, porjects outwardly as a handle.

Having thus described my invention, I claim:
