MARK F. B ENNAN, or SCRANTON, PENNSYLVANIA, ASSIGNOR TO INTERNATIONAL 1 "rnx'rnoox COMPANY; or SCRANTON, PENNSYLVANIA, A CORPORATION or PENNSYLVANIA STOCK FEEDING-MAGAZINE FOR PRINTING TRESSES Application filed Mlarch 25, 1931. Serial No. 525,270.

and in which means is provided for enabling the replenishingof stock being fed as often as may be necessary and without stopping the press or in any way interfering with its The invention has particular reference to, and is addressed to the improvement of feed ing magazines and presses of the type disclosed and referred to in UnitedStates Lettors Patents issued to Kluge et a1. 1,621,546

r and 1,621,547, March 22, 1 927, and 1,6594%,015, Dec. 4, 1928. In feeding magazinesof the type exemplified in the Kluge Patent 1,694,- 015 only a limited amount of stock can be stored and thus it is necessary that constant attention be given to the press, in order that the used stock may be replenished in time.

Therefore, in its more detailed nature, the invention seeks to provide an improved stock feeding magazine in which is provided two cooperating and yet independent stock followers each capable of imparting feeding movement to the stock and which are independently movable to enable one to continue the feeding function while the other is moved back to receive a replenishing stock to be thereafter fed with the now partially exhausted previously supplied stock.

The invention further resides in the novel construction of the followers and the driving means-therefor. 1 i

The invention further resides in the novel construction and arrangement of the stock supporting and guiding devices.

1 With these and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by following the description, the ap- In the accompanying drawings which illustrate one embodiment of the invention,

Like reference numerals designate corresponding parts throughout the several figures of the drawings.

In the drawings, I have shown only so much of a printing press of the platen type as is necessary to illustrate the application and operation of my improved stock feeding magazine. In the drawings, 1 designates the platen of the printing press on which the stock is to be printed and over which the stock delivering or translating devices operate,'said devices being in the nature of pneumatic cups 2 and 3 which come forward, grip thefprinted stock and remove it from the platen and deposit it upon the receiving shelf 4. See Figure 1. These translating devices are constructed and operated in a well known manner disclosed in U. S. Patents 1,621,546 and 1,621,547 hereinbefore referred to. As these devices form no part g of my present invention, further detailed description thereof is thought to be unnecessary. l

A table or bed-plate 5 is supported at one side upon standards 6 resting upon a part of the press frame and at its opposite side as at 7 upon a supporting column. The devices 6 and 7 afford an adjustable mounting for the table which mounting may be understood by reference to U. S. Patent 1,694,- 015 hereinbefore referred to. As in the patent referred to, by bed-plate 5 also supports the frame members 8 and 9 which are mounted in parallel spaced relation as shown in Figures 1 and These frame members serve to support the cross shafts or rods 10, 11 and 12 of which more will be said later.

In carrying out the invention, I provide two main conduits or conveyors generally designated 13 arranged in parallel spaced relation and each including a pair of angle irons 14 disposed in parallel spaced relation and secured at opposite faces to the bar or inverted channel 15 in the manner illustrated in Figures 3, 5 and 6 of the drawings. It will be observed that the channel bar 15 is shallower than the connected angle iron flanges so as to provide a conduit trough or runway for guiding the upper flights of conveyor chains which will be referred to in detail hereinafter.

The conduits 13 are supported at their front or discharge ends upon a cross rod 16 which is in turn supported as at 17 upon the bed-plate 5, the vertical flanges of the angle irons 14 being apertured as at 18 to receive said rod. The horizontal flanges of the angle irons 14 which are positioned upwardly so as to be presented toward the stock being fed, are bent at their delivery ends as at 19 to deposit smoothly and directly upon the inclined bed-plate.

At the rear or loading ends the conduits 13 are secured together by a cross head 20 and are supported by a cross rod 21 attached as at 22 to one conduit and which is in turn supported upon a column 23.

As pointed out hereinbefore, each conduit 13 is constructed to provide a groove or runway to accommodate the upper flight of a conveyor chain 24, the depth of the runways and the width of the chains being such that the chains project approximately onesixteenth of an inch above the upper faces of the angle irons 14. The purpose of this arrangement will be described later.

At the rear ends of the conduit the chains 24 engage idler sprockets 25 mounted on stub shafts 26 supported in bearings 27 secured to the conduits and at the front or delivery ends of the conduits said chains pass over sprockets 28 secured upon a cross shaft 29 which is rotatable in bearings 30 supported by the conduits and in an additional bearing 31 secured upon the bed-plate 5. The cross shaft 29 has secured thereon an additional sprocket 32, which is driven by a chain 33, and a sprocket 34 secured on the shaft 11.

Thus when rotation is imparted to the shaft 11 that rotation will be transmitted to the chains 24 causing them to travel at like speeds. An adjustable chain tightening idler 35 may be provided and supported upon the bed-plate as illustrated in Figure 3.

Brackets 36 are secured to and depend from the conduits 13 and provide additional supports for the conduits as at 37 upon the cross rod 10.

In order to assure accurate feeding of the stock, I provide a long angle iron guide 38 supported on bracket rods 39 secured as at 40 on each of the shafts or cross rods 10 and 21 at the right hand side of the machine. A similar but shorter angle iron guide 41 is provided at the left hand side of the machine, being mounted upon a single bracket rod 42 and adjustably secured as at 43 upon the cross rod 10. The guide 41 may be moved along the rod 10 so as to vary the space between the guides 38 and 41 as desired.

Mounted on bracket rods 44 secured as at 45 upon the shafts or cross rods 10 and 21 is an auxiliary conduit comprising an angle iron 46 and a channel beam 47 secured upon the angle iron and forming a groove or runway for the upper flight of an auxiliary conveyor chain 48, which like the chains 24 projects approximately one-sixteenth of an inch above the runway.

At the respective ends of the auxiliary conduit, the conveyor chain 48 passes over idlersprockets 49 rotatable on stub shafts mounted in bearings 50 secured to the angle iron 46. The lower flight of the chain 48 passes over an additional supporting bracket 51 mounted as at 52 upon the angle iron 46 and over a driver sprocket 53 secured on the shaft 29 hereinbefore mentioned. It will be noted that the shaft 29, to which rotation is imparted from the shaft- 11, serves to impart stock feeding movement to both the main and auxiliary conveyor chains 24 and 48 (see Figures 3, 4 and 5).

A guide rod 54 is supported in brackets 55 secured to the auxiliary conduit angle iron 46 and bears parallel spaced relation to the conduit for a purpose that will be come apparent as this description progresses.

The main stock follower which is moved along the main conduits 13 by the chains 24, disclosed in detail in Figures 2, 3 and 10, includes a base 56 equipped with depending lugs 57 adapted for removable connection with the chains 24 as indicated in Figures 6 and 10. Mounted on the base 56 is a pair of upstanding lugs 58 to which the standards 59 are pivotally connected as at 60, said standards being connected by face plates 61 to provide a rigid followerback for engaging the stock pack. A kneejointed support 62 is provided and pivoted as at 63 to the base and as at 64 to the upper face plate 61, a clamp screw 65 being provided .at the joint so as to enable securing of the knee-joint to hold the follower-back 59, 61 at the desired inclination to the vertical. From the foregoing, it will be obvious that the main follower may be bodily removed from the chains and replaced thereon in different positions at will.

The auxiliary follower fully disclosed in Figures 2, 5, 7, 8 and 9 of the drawings,

includes a slide bearing head 66 slidably mounted on the guide rod 54 and equipped with a bracket arm 67 which is bifurcated to form a recess in which an end of the follower blade 68 is pivotally mounted as at 69. A face plate 70 is secured to the blade 68 and serves with that blade in providing means for engaging the stock being fed in a manner to be described in detail hereinafter. y. i p

The plate 70 carries a hold-down lug 71 positioned for engaging the upper edges of the stock in the manner illustrated in Figure 4 of the drawings, andthis lug is adjustably mounted at 7 2 so that its position may be varied to suit conditions of operation.

The blade 68 is extended a short distance beyond its pivotal mounting and provided With a stop lug 73 for engaging the bracket arms 67 when the blade is swung to the inoperative position illustrated in dotted lines in Figure 7. The slide head 66 is also provided with a lug 74 which will engagethe adjacent edge of the angle iron 46 when the auxiliary follower is swung to theposition illustrated in Figure 8. A chain engaging lug 75 is adjustably secured as at 76 upon the bracket 67 and projects downwardly for engagement with. the conveyor chain 48 when the parts are positioned operatively as indicated in full lines in Figure 7. When the auxiliary follower is swung to the position illustrated in Figure 8, the lug 7 5 will be moved out of engagement with the chain 1-8 so that movement will not be imparted by the chain to the auxiliary follower.

A retchet mechanism generally'designated 77, and to which movement is imparted by a vertical reciprocation of the rod 7 8, serves to impart rotation to the cross shaft 11 necessary to transmit feeding movement to the main and auxiliary chains 24 and 48. It should be understood that therod 78 is reciprocated in proper timed relation with the operation of the printing press but since this particular mechanism forms no part of my present IDVGIItIOIl, detalled description thereof is thought to be unnecessary. This ratchet driving mechanism is disclosed in detail in U. S.. Patent 1,69d,015 hereinbefore referred to. The gage arm 7 9 mounted on thecross shaft 12 is likewise describedin detail in thepatent. ust referred to and or. other manipulation of the machine.

since this gage performs the same function disclosed in that patent and in no way modities the feeding magazine combination disclosed herein, further detail description thereof is thought to be unnecessary.

The printed stock translating devices generally indicated at 2 and 3 in Figure 1 of the drawings, come forward each time the printing of a stock unit is completed, are lowered onto the printed stock to grip the same, and are again lifted and drawn rearwardly to deposit the printed stock onto the shelf 4. These translating devices are carried by a slide 80 slidable along guides 81 to the lower one of which a block 82 is secured. The necessary lifting and lowering of the translating devices is imparted through the block 82 by the lift rod 83 which is connected to a pin 8% passing 4- t J- l L111 ough a slot in the side wall or the block and attached to a head secured on the end of the upper guide 81 as will be evident by reference to Figures 1 and 11 of the drawings, The sliding or fore and aft movement of the translating devices is imparted by arm and linkconnections 85.

le lifting and lowering and fore and aft movement of the translating devices 2 and 3 is effected by mechanism disclosed in U. S. Patents 1,621,546 and 1,621,547 hereinbefore referred to and as the specific features form no part of the present invention disclosure of the details of the opera ing devices is thought to be unnecessary herein. The parts disclosed herein are disclosed because their movement is employed to actuate devices forming a part of my invention and which serve to facilitate the feeding of the stock from the magazine proper onto the platen 1.

A rock shaft 86 is mounted in bearings 87 depending from the bed plate and so cured on this rock shaft is a pair of stock delivery guiding arms 88 which serve to effectively guide the stock as it travels from the magazine proper onto the platen 1 to prevent interference of portions of the stock with parts of the mechanism. The stock is translated from the delivery end of the mag:

azine proper to the platen 1 by the pneua handle 90 by. which it may be manually rocked from its operative position illustrated in Figure 1 of the drawings to an elevated position clear of the translating devices 2 and 3 thus facilitating adjustment addition to this manual means for moving the guides 88, I provide mechanically operated devices which serve to lift the guides 88 out of the way of the translating devices 2 during each operative movement of said translating devices.

In order to accomplish this purpose, I provide the rock shaft 86 with an additional crank 91 which is connected by a link 92 with the pin 84 as illustrated in Figures 1 and l of tne drawings. Thus each time the member 83 operates to lift and lower the translating devices 2 and 3 preparatory to fore and aft movement thereof, the connections 91 and 92 will be actuated to rock the shaft 86 and thus move the guides 88 out of the way of the translating devices.

In operation the main follower is mounted in suitable position upon the conveyor chains 24 and the auxiliary follower 68, 7 O is moved to the position illustrated in Figure 8 and then slid along the guide rod 54 so as to lie against the main follower as illustrated in full lines in Figure l, thus providing a composite or 2part follower. It will be obvious that the bracket 67 is so inclined relatively to the slide head 66 as to bear substantially parallel relation to the active face of the main follower. As the present operation proceeds, the rotation imparted to the shaft 11 will be transmitted to the chains 2% and 48 as hereinbefore described, serving to move the composite follower and the stock pack forwardly along the conduits 13 to be fed one by one out of he front or delivery end of the magazine by the pneumatic translating devices 89 in the manner hereinbefore referred to. The parts continue to operate with the composite follower 68, and 61 positioned relatively as just above described until the pack of stock becomes almost exhausted and needs replenishing At this time, the main follower 56, 61 is lifted bodily from the chains 24 and moved back to a suitable position upon the chains 24 (see dotted lines in Figure 4) so that a pack of stock may be positioned in advance thereof for replenishing the stock being fed. By now lifting the chain engaging lugs 57 clear of contact with the chains 24, the main follower may be slid along the conduits 13 to force the stock replenishing pack against the rear face of the auxiliary follower 68, '70 which has been carrying on the stock feeding function. This accomplished the auxiliary follower 68, 70 may be swung to the position illustrated in Figure 8, slid rearwardly along the guide rod 5 4: and again swung down behind the pack of stock immediately in advance of the main follower as indicated in Figure 4.

The operation above described may be repeated as often as necessary to complete a particular job or jobs and thus it is never necessary to stop or interfere with the op eration of the press for the purpose of replenishing the stock being fed thereto. It will be obvious that with this equipment it is possible for a single operator to look after several machines whereas heretofore this has been impossible.

It is of course to be understood that the details of structure and arrangements of parts may be variously changed and modifled without departing from the spirit and scope of my invention.
