STAPLE-BINDING DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 615,255, dated December 6, 1898.

Application filed December 31, 1897. Serial No. 665,167. (No model.)

To all whom, it may concern:

Be it known that I, LUTHER O. OROWELL, a citizen of the United States, residing at New York, (Brooklyn) county of Kings, and State of New York, have invented certain new and useful Improvements in Staple-Binding Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present improvements relate in a general sense to that class of stapling mechanisms especially adapted for attachment to a web-printing machine to form a part of the delivery mechanism thereof, whereby the plicated material in the form of'webs or sheets may be bound together in packs on the line Of ultimate folding thereof by means'of staples made and set therein during the onward progress of the said plicated packs for final delivery, and thus form a completed product, such as a pamphlet or newspaper,whose leaves are bound together in the form of a book-like product. In a general sense the type of such machines is comprehended in Patent No. 510,528, and more specifically the improved machine is of the class in which the staple forming, presenting, and inserting mechan isms are contained within the confines of a rotary carrier supporting them, which carrier also supports the wire length supplying means delivering material to form the staple, which class has its type disclosed in Patent No. 510,843.

In the drawings annexed hereto and forming a part Of this specification, Figure 1 is a sectional view of the stapling and folding cylinders, showing the parts of the left-hand stapling mechanism of Fig. 4 in the position in which they are just before the stapling operation. Fig. 2 is a similar view of the same parts at the moment of driving the staple. Fig. 3 is a plan view of a stapling mechanism carried by the carrier B, the line of sight being that of the arrow 3 in Fig. 2. Fig. 4 is a section on the line 4 4 of Fig. 1, the line of sight being in the direction of the arrow 4 in Fig. 1 and the cutting mechanism being Omitted for perspicuity. Fig. 5 is a view of a portion of the parts shown in Fig. 1, the position,

however, being that in which the staple is about midway between the point at which it 'is formed and the point at whichit is set. Fig. 6 is an end view of the carrier. Fig. 7 is a plan view, on an enlarged scale, partly in section, on the line 7 7 of Fig. 6, the point of view being in the direction of the arrow 7, the stapling mechanism being that shown on the right in Fig. 4. Fig. 8 is aview, partlyin section, of the mechanism shown in Fig. 7, the line of sight being indicated by the arrow 8.

Fig. 9 is a section on the line 9 9 of Fig. 7.

Fig. 10 is a detail view of the staple bending and lifting disks shown separately, the stapling mechanism being that shown in the left in Fig. 4, the View being'inverted from that shown inFig. 4. Fig. 11 is a side view of one of the anvil-carrying arms and the plate to which it is'attached, the point of view being between the arms 1 and 2 on the right-hand side of Fig. 4. Fig. 12 is a plan view of the same detached from the cylinder. Fig. 13 shows two perspective'views of one of the guide-blocks, and Fig. 14 shows the stapleleg-clenching anvil-block and the adjustable plate upon which it is mounted.

The stapling mechanisms on the right and left hand ends of the carrier are substantially alike and the parts of each are symmetrically placed with reference to each other. A description of one will therefore suffice for both.

Referring to said drawings, the web or webs of paperA are led to the staplingmechanism from any appropriate printing and folding or associating mechanism between the carriers B C, which support the stapling mechanism and which may also carry cutting and folding mechanisms, although, of course, if preferred, the cutting and folding operations may be performed by other means. The staple-forming mechanism consists of two arms 1 2,which are carried by the plates 3, fixed to the cylinder-shell, these arms being provided with shoulders or abutments 4, which together form an anvil, against which the wire is bent to form the staple. The wire is fed from spools 5 5, mounted upon the end of the cylinder between guide-rollers and feeding-disks 6 7, and into guiding-slot 8,which latter conducts the wire to a position where it lies against the anvil'shoulders 4. The feeding-disks 6 7 are in the construction shown cut away, so as to make the feed intermittent; but, if desired, the feeding-disks may be made continuous, the parts being so arranged in that case as to give the wire clearance for move ment as it is fed forward.

The staples are bent by a bender consisting of two forming-disks 9 10, mounted upon a shaft 11, journaled in the cylinder, these disks 9 10 being placed one on either side of the arms 1 2 and having shoulders or dies 12 13, which cooperate with the anvil-shoulders at to bend the staple, as best shown in Fig. 7. Shoulder 12 also serves as a knife to sever the staple-forming length of wire. Space is left between the arms 1 2 and the disks 9 10 for the reception of the staple-legs when bent.

Mounted on the shaft 11 between the disks 9 10 and also between the arms 1 2 is athird disk 14. The disk 14 may be provided with a cam-like surface or a rise 15, which acts to lift the middle portion of the staple after it has been bent over the anvil-shoulders a and into the position shown in Fig. 5. The disks 9 10 are also provided with similar rises 16 17 for the purpose of lifting at thesame time the legs of the staple, so that the staple as a.

whole shall lie tangentially to the circumference of the disks 9 and 10. The disk 14: is also provided immediately behind the rise 15 with a shoulder 18, which engages with the central portion of the staple and carries it forward when it is lifted above the anvilshoulders, as shown in Fig. 5. The staple is retained in this position by a curved spring or metal strip 19, attached to the framework of the carrier by a bracket 20. The three disks 9 10 It may be made separate and fixed to the shaft, or they may be made in one piece.

At the point where the circumference of the disks 9 1 comes nearest to the circumference of the carrier 13 are mounted two guide-blocks 21 22, which are dovetailed into block 23, fixed to the plate 3, and sliding in the said block radially to the carrier. These guide-blocks are placed opposite to each other in the direction of the length of the cylinder and with the space between them equal to the width of the staple and are provided upon their inner surfaces with grooves 22L 24!,which are curved outwardly from a direction tangential to the circumference of the disks 9 10 to a direction radial thereof, as shown in Fig. 5. These blocks are provided with lugs 26, against which bear springs 27, pressing them outward, and their outward movement is limited by the contact of lugs 28 with the surface 29 of recesses in blocks 23.

In the normal position of the guide-blocks 21 22 when the same are pressed outward by the springs 27 the guiding-slots 24 24: register with the space between the strip or spring 19 and the disks 9 and 10, so that as the shoulder 1S revolves it will push the staple into the slots, as shown in Fig. As the guideblocks come to the staple-setting point they are pushed in by the surface of carrier B against the pressure of springs 27 to the position shown in Fig. 2, the disks 9 10 being provided with the recesses 31 to permit this inward movement. The disk 14 is provided just back of the shoulder 18 with a gradually-elevated portion 32, which serves to lift the staple by hearing against-its crown after the staple has passed into the guiding-slots 2i 2%, as shown in Fig. 2, the rear portion of which acts as a setting-bed for the staple. The rear part of this projection 32 is made with side flanges 33, giving the bearing-surface a width equal to the total width of the staple, so that the whole of the central portion of the staple will be supported while it is being set. The plates 3 are recessed, as shown in Figs. 11 and 12, to permit these flanges to pass as they rotate.

The staple-legclenching anvil-block 34, Fig. 14, is mounted upon a plate 35, which is held to the carrier by set-screws 36 37 and is adjusted by loosening these screws and turning the eccentric screw-bolt 38.
