FEED STRIP SEVERING DEVICE Augustus J. Richards, Lakewood, Ohio, assignor to Bonnar-Vawter, Incorporated, Cleveland, Ohio, is corporation Application September 23, 1952, Serial No. 311,123

7 Claims. (Cl. 164-60) This invention relates to a feed strip severing device, the same being particularly suitable for incorporation as an attachment in various business machines.

The advantage of such a device will be readily understood when it is explained that such business machines are those which use a continuous manifolded. business form, the same being. comprised of record sheets interleaved with transfer sheets, and fastened together at. their edges, or one edge as the case may be, one of those edges or both being provided with feed holes or perforations formed in a strip. adjacent the edge of the manifolded form, which feed strip also serves to fasten the various forms in position, and likewise maintain the transfer strip in location for carrying out its function.

As is well-known, continuous forms which are to be inserted in a typewriter or billing machine, are generally provided with the feed holes or perforations above referred to, which feed holes are adapted to be engaged with pins carried by the platen of the machine, whereby the manifolded forms as a group are fed through the machine as the Operations. are performed thereon, such as preparing an invoice or other material which requires the use of such manifolded forms.

The manifolded forms involve usually several copies or record sheets, thus are rather bulky in thickness, and it is necessary that they be fastened together by the means as. above mentioned, but after the usual typing or billing operation is carried out thereon, separation of the forms is required. Thus, the feed strip. is itself no longer necessary and it is advantageous to remove this strip as the form is delivered frorn'the machine without the necessity for manipulation by hand.

It is therefore a principal object of this invention to provide an attachment of the nature generally referred to, which may be arranged on a machine of the nature involved, so as to effect rapid and complete removal of the, strip in which the feedholes are located, and at the same time effect a separation of the manifolded forms.

It is a further object of this invention to provide a novel unit in which a cutter is mounted, which cutter may preferably be a rotatingtype and driven by a small motor, suitable adjustment being provided for the cutter.

It is a further object of thisiinvention. to provide a unit, including a rotating cutter which unit may be mounted upon suitable provisions made therefor in connection with the machine, and adjusted therein, so as to accommodate various sizes of forms or widths, the units being generally furnished in pairs in such machines.

It is a still further object of thisinvention, to provide a novel unit ofthe class described, which includes a mounting bracket, the mounting bracket having, fastening and, adjusting means therefor, together with a small motor pivotally supported on the bracket by means of a suitable stud engaged with the motor, the stud. in turn having at its outer end a cutter guard to prevent injury to the operator of the machine; the motor being further nited States Patent 2,779,41 l Patented'Jan. 29, 1957 adjustably maintained in its pivoted position on the bracket by suitable fastening means therefor.

It is a still further object of this invention, to provide a unit including a mounting bracket, which mounting bracket is provided with a suitable table fastened thereto, and the motor is mounted pivotally on the bracket and adjustably fastened thereto, and the cutter guard is fixed so as to move with the motor and substantially enclose the cutter, and in addition a suitable hold-down arm is furnished so as to maintain the forms being severed in proper position for continuous operation.

Other and further objects of this invention will be understood from a consideration of the specification appended hereto, and illustrated in the drawing wherein:

Figure 1 is a top plan view of the unit, including the motor, the table, the cutter, the guard and the holddown arm.

Figure 2 is a view in end elevation of Figure 1, still I further illustrating the various elements above referred to and further showing the form of mounting for the bracket provided.

Figure 3 is a sectional elevation view taken about on the line 3-3 of Figure 1, looking in the direction of the arrows illustrating the relationship between the bracket and the motor mounted thereon.

Figure 4 is a fragmentary sectional view taken about on the line 4-4 of Figure 2, looking in the direction of a the arrows, illustrating the clamping means for mounting the bracket upon instrumentalities provided in the machine for which the unit is adapted to be used.

Referring now to Figure l in the drawing, the same illustrates a motor generally designated 1, the same being of very small size and a relatively high speed operating motor, a bracket generally designated 2, and a shelf or table 3 fastened to the bracket. As more clearly shown in Figure 2, the table 3 is fastened to the bracket 2 by means of suitable screws 4. The bracket 2 is further provided atits lower portion with a clamping. arrangement designated 5, which arrangement includes a clamping plate 6, and a substantially U-shaped member 7, together with a stud 8 threaded at 9 by means of which a knurled nut 10 is caused to engage the plate 6, and in turn clampingly support the bracket 2 upon mounting rods 11 which are only partially shown and are provided on the business machines to which this device is applied. It will be apparent that this arrangement provides for longitudinal adjustment of the device along the rods 11, since the same extend behind the platen of the machine, and are suitably engaged with the body of the machine, as will be readily understood.

In order to mount the motor 1 upon the bracket 2, a stud 12 is provided, the stud 12 being threadedly engaged at 13 in the frame of the motor, and having an enlarged portion 14. The threaded portion 13 passes through a suitable opening 15, in the bracket 2. It will be apparent that the motor may therefore be pivotally moved on the bracket with the stud 13 as. the pivot point therefor.

The motor shaft 16, shown in Figure 1, and also in Figure 3, extends from the central portion of the motor, in substantial parallelism with the stud 12 previously mentioned, and has an extension 17 thereon. At the outer end of the extension 17, is a round cutter 1S, fastened to the extension 17 by a suitable knurled nut 19. The bracket 2 is provided at its central portion as shown in Figure 3, with an enlarged opening 29 therein, so that when the motor is pivoted about the stud or pivot point 13, the shaft 16 may have free movement within limited range.

The stud 12 at its outer end, is provided with a cutter guard 21, same being formed as shown in Figiire 2,

with a mounting opening 22 whereby the same is supported on the stud 12, being maintained in its position on the stud by a suitable set screw 23. The guard 21 is formed so as to extend at 24, substantially around the cutter 18, and prevent injury as will be apparent. Spaced from the mounting hole 22 of the guard 21, on the outer end of the guard is a mounting opening 25, in which is seated a hold-down arm 26, the same being preferably of round wire or the like, bent as shown in Figure 2 so as to extend downwardly and thence forwardly above the table 3. The hold-down arm 26 is suitably maintained in adjusted position by a set screw 27.

It should be noted that the table 3 is provided with a slot 28 therein, into which the cutter 18 may pass under certain conditions for adjustment of the motor with respect to thebracket. The various adjusted positions of the motor with respect to the bracket, are maintained by a stud member 29, suitably fastened to the motor, and extending through a slot 30 in the bracket. The stud member 29 is threadedly engaged at its outer end with a knurled nut 31, so that appropriate adjustment of the nut 31 toward and from the bracket will maintain the motor in its adjusted position as will be apparent.

It should be understood that under many conditions, a pair of the above described devices may be preferably provided, where the manifolded forms generally indicated as A in Figure 1, are provided with feed holes or openings 32, at'opposite edges in a feed strip. However, further eference will not be made to the provision of a pair of devices, inasmuch as they would both be substantially the same, being of opposite hands-otherwise involving the same elements above specifically mentioned.

In operation therefore, it will be understood that as the manifold forms A come from the machine upon which the unit or devices are mounted, the feed strip designated B of the forms A, will be placed in alignment for severing with the cutter l8, and the motor may be energized appropriately so as to rotate the cutter. Since the forms A will be held against the table 3 by means of the holddown arm 26, feeding of the forms by the machine platen in which are provided the usual fingers for engaging the opening 32, will cause the forms as a unit to move through and between the respective devices. Since the cutter 13 is rotating, the strip B will be severed from the forms as illustrated in Figure 1, and thereafter the forms themselves will be separable, usually being provided with a cross perforation for individual forms if furnished.

Where there are a large number of forms, which will thus make a rather thick or bulky pack, it will be apparent that the cutter 18 may be adjusted suitably with respect to the table 3, or as the cutter is sharpened if required, further adjustment may be made so as to effectively sever the feed strip as will be understood.

There has thus been illustrated and described, a novel feed strip severing device, particularly adapted for use with manifold forms, which include a perforated or punched strip along the edge or edges of the forms, which strip is desired to be severed after typing or billing operations have been carried out upon the forms themselves.
