FILING MECHANISM FOR LETTER-FILES.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed July 8, 1915. Serial No. 38,811.

mechanisms for letter files and the like which are provided with a perforating attachment, operated by the lever of the said filing mechanism.

Vith the hitherto disclosed filing mechanisms of this kind the perforating attachment is disposed similar to the known perforators independently between the stems of the filing pins, and is operated by lifting the lever of the filing mechanism, whereupon the letter, sheet of paper or the like may be introduced into the 'perforator; then the said lever is again depressed and thereby the paper is perforated. For removing the papers from the perforator and for filing them in the file it is necessary to each time throw the said lever up and down. Filing mechanisms which are constructed on this principle do not afford in their operation any advantages over the common filing mechanisms used together with the common perforators, that is to say, when the perforating and the filing are performed as two separate operations, as they require separate manipulations for each operation. lVith the object of improving on filing mechanisms combined with perforators in this direction, the perforating attachment according to the present invention is attached in such a manner to the filing mechanisms and of such a design, that the perforation is performed simultaneously with the filing of the papers. For both operations,

therefore, only one single manipulation of I the lever of the filing mechanism by throwing it up and down is required, so that no sepa ate operation is necessary for the perforation, as the perforation is periormed by the work of filing.

For obtaining the object known perforating sleeves are displaceably arranged on the stems of the filing mechanism and said sleeves are operatively coupled in such a manner with the lever ofthe filing mechanism that when the latter is closed the said sleeves will perforate the papers placed on the said stems, so that they are immediately filed, without requiring any further operation. For insuring an even filing of the papers a stop is provided between said stems on the level of the point at which the perforation is performed, so that the papers may be laid against said stop during the perforation.

The coupling between the perforating sleeves and the filing mechanism is effected by means of a lever which may by means of two dogs fitted to the lever of the filing mechanism lee-engaged with or disengaged from the perforating sleeve. The arrangement is such, that the dog operating said lever when the filing mechanism 1s being closed, can come into action only when the bridges of the filing mechanism have already reached the upper ends of the straight filing stems, so that the paper is steadily held during the perforating operation.

In another embodiment of the file the stop is movable, so that it may not obstruct the manipulations in filing and pressing down the papersyand it is coupled in such a manner with the closing and perforating mechanisms that when the mechanism is closed and the papers therein are perforated, it will be automatically moved away from its operative position, and when the mechanism is again operated, it is again automatically moved back into operative position.

In the accompanying drawings two embodiments of the present invention are exemplified. i

Figure 1. is a front elevation of the closed 'iechanism. Fig. 2 is the same view of the open mechanism. Figs. 3 and 4: are similar side elevationsand Fig. 5 isa plan view of the mechanism. Figs. 6-8 illustrate another embodiment, Fig. 6 being the. front elevation of the file opened with the perforating attachment under tension, and Fig. 7

a similarvlew of the two mechanisms at the opposite terminal position. Fig. 8 is a front ele ation of Fig. 7 showing the operative position of the stop in dotted lines.

The filing mechanism which is fitted in known manner 'in a letter file or the like, consists, as usual, of the base plate 0., the straight filing stems Z) and the swiveling bridges c with the lever (Z. The bridges c normally held out of alinement with the stems b by means of a spring 2, Figs. '3 and 4;. which is mounted on the base plate a. By means of lever, (Z, the bridges are rocked to and fro in the known manner, for opening and. closing the filing mechanism, re spectively. l

According to the present invention perforating sleeves 0 are slidably fitted on the filing stems b. The said sleeves 0 are connected to each other at their lower end by means of a plate 39. Under this plate is disposed a flat spring 2' or the like, which tends to hold the said sleeves 0 in the raised position shown in Fig. 1. To a plate or the like attached to lever (Z is linked a dog 6, which has below a beveled pressing edge. At both sides of this dog 6 the pins 7 and g are fitted to the lever (Z in such a manner, that when the lever is lifted the pin 9 and when the lever is pressed down the pin 7 will strike against dog 6 and move the same in the one or the other direction, respectively.

Between the stems of the filing mechanism is disposed the stop or abutment frame h, which allows of perforating papers at a constant distance from their rear edge.

The operation of the filing mechanism is as follows: Vhen the lever (Z is lifted, that is to say, when the mechanism is opened the dog 6 is pressed forward by pin 9 and with its lower edge it rides on the plate 72 press ing same downward, and with it the perforating sleeves 0 against the action of spring 2. Thereby also the bridges c are swung back in the usual manner, so that the filing mechanism is opened (Figs. 2 and at). Now he paper, letter or the like, to be filed is inserted until it bears with its rear edge against or enters into the upper part of the abutment frame h. hen, now, the lever (l is pressed down, the bridges c are again swung forward in the known manner and meet the stems'b, whereupon the pin f bears against the dog 6 moving the same backward so that the plate 79 is released and is forcibly pressed upward together with the perforating sleeves Q by the action of spring 2'. The sleeves 0 perforate the paper so that the latter may simply he slipped down and filed.

In the embodiment shown in the drawing the dog 6 is provided with a cut-away portion or a slot, in which the pin 7 engages during the downward throw of the le er (Z un il the filing mechanism has been closed, that is to say. until the bridges 0 have met the stems b. The same obiect might also be o tained by suitably arranging a pin f or by.

other means.

In the embodiment shown in Figs. 6-8 the stop or abutment frame consists of a straight grooved bar 7' which is attached to two supports 20. These supports are pivotally fitted to the baseplate of the mechanism and provided with arms 00, which are hinged to the connecting plate 79 of the two perforating sleeves 0. A pluralit of springs 3 are interposed between the plate 7?. and base plate a for normally forcing the sleeves upwardly on the stems 0.

When the mechanism is opened, and the plate 72 is in its lowest position, the springs are thus under tension (Fig. 7), and the stop has the operative position shown by dotted lines in Fig. 8. l Vhen the mechanism is closed, the plate 2) is released and moved upward by the action of the springs, so that the arms 00 of the supports w linked thereto are carried upward and the stop is moved back into the position indicated by full lines in Fig. 8. The stop is again automati cally moved back into its operative position when the mechanism is opened, as will'be clearly evident from the drawing.
