COLLECTING Am) STAPLING MECHANISM.

Specification of Letters Patent. Pate'nted June 15, 1920.

Application filed August 16, 1919. Serial No. 317,877.

To all whom it may concern:

Be it known that I, EDWARD P. SHELDON, a citizen of the United States, residing at New York city, county of lxings, and State of New York, have invented certain new and useful Improvements in Collecting and Stapling Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

- This inventio relates to certain improvements in collec ing and stapling or stitching mechanism, and has been designed particularly for use with printing machines.

In certain classes of printing machines as heretofore constructed, provision is made for running a web or sheet through without collecting, or cutting and collecting sheets cut from a web and stapling the collected product, or running through such cut sheets without collecting. Where such collected product was to be stapled, however, a special stapling mechanism, usually a cylinder, had to be added to the machine. Vhere sheets were cut from a web and collected this stapling cylinder had to be located below the cutting and collecting cylinders, and this position made it difiicult to get at the stapling cylinder to adjust the wire feed and for other purposes, and where this stapling cylinder was installed in a machine not especially designed for it, certain other mechanisms of the machine had to be moved to accommodate the cylinder, and the stapling cylinder was difficult to install.

It is the especial object of the present invention to produce an easily accessible mechanism in which a collecting and stapling or stitching mechanism are supported in a common carrier. so that a web or sheet may be run through the machine without stapling or sheets may be collected and stapled without any change in the mechanism other than silencing the stapling or the collecting mechanism when desired. It is a further object of the invention to produce such mechanism in which the carrier which supports the collecting and stapling mechanism may also carry a cutting mechanism by which sheets may be cut from a web and, if desired, collected and stapled, or run through straight or collected without stapling.

\Vith these and other objects not specifically referred to, in view, the invention consists in novel parts and combinations which will be described in connection with the accompanying drawings, in which 2- Figure 1 is a side view partly broken away and partly in section of a carrier for supporting both the collecting and stitching adjusted to collect and staple a product.

Fig. 7 is a detail view partly broken away and partly in section on line 7--7 of Fig. 2, showing the operating mechanism in noncollecting position.

Fig. 8 is a detail sectional view partly broken away showing the operation of the stapler in taking a staple length.

Fig. 9 is a plan view of the staple former.

Figs. 10, 11, and 12 are detail sectional views illustrating the operation of clenching a staple.

Machines constructed in accordance with the invention will include a support or carrier capacitated to support both a mechanism for collecting sheets and a mechanism for stapling or stitching the collected product,

and the support or carrier embodying the invention in its best form will be capacitated to support cutting devices for cutting the sheets which are to be collected and stapled from a web, and these mechanisms will be of such character that any or all of them may be silenced or operated as desired, or removed from the carrier if not wanted, depending on the particular product which it is desired to produce.

The particular mechanisms employed may be varied within wide limits, but in the best constructions, the collecting, cutting and stapling devices will be carried on a rotary carrier, such carrier being employed to effect high speed production. In the particular construction illustrated, there is provided a rotary carrier in the form of a cylinder 1, mounted on a shaft 2 suitabl supported in bearings 3, on a frame 4 0 any usual or desired construction. This cylinder 1, in

the construction illustrated, is capacitated to support collecting, cutting and stapling mechanisms which may be of any usual 01' desired character. In the particular construction illustrated, a collecting mechanism is shown supported on the cylinder the sheet taking devices of which are shown as pins 5. These pins are provided in sufficient number along the cylinder to effectively take and hold the sheets, and as they are similar in construction and operation but one will be described. These pins work in guide slots 6, formed in the cylinder wall, the shank of the pin passing through a bar 7, and the pins are normally held in retracted or non-taking position by springs 8 taking against a projection 9 on the pin and the wall 10 of a recess formed at the inner end of the slot 6. Beyond the bar 7 the pins are formed with a slotted head 11, in which takes an actuating pin or stud 12 whichis operated to throw the pin into sheet taking position at the proper time, this slotted head providing a lost motion for purposes hereinafter referred to. This pin or stud 12 is carried on an arm 13 on a cam shaft 14 extending across the cylinder and (see Fig. 2) having a cam roll 15 which takes in the groove 16 of an operating cam 17, which is mounted loosely on the carrier shaft 2, this cam being driven through connections hereinafter referred to.

Machines constructed in accordance with the invention will be capacitated to support a mechanism for securing together the plies of a collected product where such a product is desired. While this securing meansmay be of various characters, it w1ll be carried by and operated from the cylinder 1, which carries the collecting pins. In the particular construction illustrated, these securing devices are a stapling mechanism adapted to form and insert wire staples in the collected product at the points desired, and these staplers may be of an 'usual construction, and any desired num er, two such being .illustrated arranged along the cylinder to manner.

staple the product at two points in line with each other. These staplers are of the same construction and are operated in the same As shown each includes a staple forming plunger 18 which takes a wire length cut off by a suitable mechanism, not illustrated and which cooperates with a'staple forming horn 19 eccentric to the carrier 'to form the legs of ithe staple in the usual manner. 7 I

In constructions where the staple forming and inserting mechanism is carried on the collecting cylinder means are provided whereby after the staple has been formed, it may be withdrawn within the periphery of the carrier so that the staple will be out of the way of the sheet which is to be collected on the carrier. In the best constructions, furthermore, means will be provided to operate the stapling mechanism so that the staple is positively inserted in the product as distinguished from the ordinary staple insertion effected by rolling contact. In the particular construction illustrated, there s provided a hollow head or block 20 set lnto the cylinder wall, this block being provided Withways 21 (see particularly Fig. 9) in which is arranged to slide an anvil plate 22 which effects the positive insertion of the staple in the product at the proper time. This plate (see Fig. 8) is provided with ears 23 to which are connected an arm 24 pivoted to an arm 25 loosely mounted on a shaft 26 extending across the cylinder frame, the anvll being reciprocated so as to be drawn out of the way of the formed staple as it is drawn into the carrier by the staple formmg plunger to clear the carrier surface.

-The staple forming plunger is mounted and operated in any usual manner. In the partlcular construction illustrated, it works through guide slots 27 formed in the plate 22, before referred to. The inner end of the plunger is recessed (see Fig. 10) to form hooked lugs 28 in which work actuating pins 29 carried on each side of a lever arm 30 clamped to the shaft 26. This shaft 26 is operated to actuate the plunger through a cam (see Fig.2) arm 31 having a cam roll 32 which takes in a groove 33 of a cam 34 loosely mounted on the end of the'shaft 2 opposite the pin operating cam 17, before referred to. The parts are so arranged and proportioned that the plunger is forced outwardly beyond the carrier to take the wire length and after it is taken and the staple formed 1s withdrawn so that the face of the plunger and the ends of the legs of the staple carried by it are within the periphery The stapling mechanism may be silenced when no stapling is desired in any usual way, as for instance stopping the wire feed;

.or removing the stapling plungers.

In machines embodying the invention in its best form for convenience in construction, the cam for operating the'collecting pins will be utilized for operating the clenching anvil. While various constructions may be employed for this purpose, in the particular construction illustrated, the

' shaft 14 has positioned thereon an arm 37 to which is pivoted at 38 one end of a cross over link 39, the other end of this link being pivoted at 40 to the arm 25, before referred to, through which the anvil is operated. In order that the collecting pins and anvil may be operated independently of each other, a lost motion is provided both for the pins and anvil, the slotted head 11 of the pin, before referred to, being utilized for this purpose, and the guides 21 in which the anvil slides being sufiicientl long 'to permit the anvil to have a su cient idle movement therein.

Machines constructed in the best form of the invention will include cutting mechanism for severing sheets from a web, and in the best constructions this cutting mecha- Y nism will, be also carried on the carrier 1,

this cutting mechanism including the usual cutter knife 41, mounted in the carrier with which cooperates the usual spring seated cheeks 42, the c'iitter knife cooperating with a cooperating cutting wood 43 on the cylinder 36, before referred to.

Machines constructed in accordance with the invention will include means whereby the stapling mechanism may be operated to insert a staple at every revolution of the cylinder or carrier, where a collected prodnot is being sent through and no further collecting is to be done, or if collecting is to be done, at a number of revolutions, and the collecting pins being likewise operated, to produce different products. while this may be effected in various ways, the operating cams 17 and 34, before referred to, are arranged so that they may be stationary with respect to the cylinder, which arrangement is used where a product is to be stapled at each revolution, or they may be ,given a movement with the cylinder but at half the speed thereof, so as to effect the stapling and collecting function in the particular machine shown at every other revolution of the cylinder. .As the same construction is preferably employed for each of the cams 17 and 34, but one such construction will be described. In the particular construction illustrated, referring to Figs. 2 and 7, the cam 17 is secured to a gear 44, which meshes with a gear 45 on an eccentric shaft 46. This eccentric shaft carries a gear 47, which is adapted to be thrown into mesh with a gear 48 fast on the shaft 2 of the carrier, before referred to. In the construction shown in Fig. 2, the parts are shown in the position they occupy when a product is collected, and stapled at every other revolution of the carrier. while in Fig. 46 is shown rocked to throw the gears 45 and 47 out of mesh with gears 44 and 48, in which position the. stapler is operated to staple a productat every revolution of the carrier. The pin rods, of course, are likewise in this position operating at every 7 the eccentric shaft revolution of the carrier, and when no collecting is to be done the pin points are removed so as to keep them out of the'way of the sheet. I

When the parts are irn-the position shown in Fig. 7, owing to the fact that the cams 17 and 34 are loose on the shaft, means are provided for holdin these cams stationary which means may he of any suitable character, as a pair of sliding latches 49, 50, which have slotted ends, and are secured to the bearing blocks 3, before referred to, in any suitable manner as by bolts 51.

lVith the construction shown and described a very compact arrangement is provided, all the parts of which are readily accessible and by the use of which extra cylinders and other drivin connections are omitted, and a construction has been provided where if desired'a sheet may be cut, sheets collected or stapled, orany of these mechanisms may be silenced as desired.
