SPECIFICATION forming part of Letters Patent No. 617,404, dated d'anuary 10, 1895.

Application filed August 11, 1897. Serial No. 647,786. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. MONUTT, of Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Feeders for Printing- Presses; and I do hereby declare the following to be a full, clear, and exact description- The object of the invention is to providemechanism for successively feeding separate articles, especially paper bags, to a printing press. This I accomplish by so mounting a pile or stack of bags that a carrier moving back and forth beneath such stack can be made to grasp the lowermost bag and, after withdrawing first one end from the elevated rest or support, feed the bag forward to a printing-press or the like, whereupon the carrier releases the bag and is withdrawn, so as to engage the next bag of the stack now at the bottom of the latter. A flap of the lowermost bag is freed or separated, so as to be easily engaged by means of a jet of air ejected by a pneumatic attachment.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my improved feeder. Fig. 2 is a side elevation showing the position of the gripper immediately before engaging a bag. Fig. 3 is a similar view showing the gripper in engagement with the bag. Fig. 4: is also a side elevation showing the position of the gripper as the bag is engaged by the feed-rolls. Fig. 5 is a side elevation similar to Fig. 2 from the opposite side of the feeder. Fig. 6 is an enlarged view in perspective of the carrier and gripper. Fig. 7 is an enlarged view with parts broken away of the links by which the necessary movements are imparted to the carrier. Fig. 8 is an enlarged perspective view of the rear end of the main operating-pitman. Figs. 9 and 10 are details. Fig. 11 is a side view of the gripper. Fig. 12 is a bottom plan view thereof. Fig.

13 is an enlarged view of portion of the ear rier, showing the mechanism for operating the gripper. Fig. 14 is a front edge view thereof. Fig. 15 is an enlarged detail of said mechanism. Fig. 16 is a viewin perspective of a portion of the support for the stack of bags. Fig. 17 is an inverted view in perspective of the folded end or bottom of a bag.

Referring to the drawings, A designates a portion of the frame of a printing-press, a a the type-carrying and impression cylinders, and a the feed-rollers bywhich the stock is fed to the press after the manner shown and described in Letters Patent of the United States Nos. 577,299 and 577,381, both issued February 16, 1897, on'applications of Charles G. Harris.

B is a supplemental frame attached to pressframe A and having a central outwardly-extended arm I), a lateral arm b and a side arm I). Thislatter arm and arm I) support a shaft 1), whereon is keyed av wheel (1 having a segmental toothed portion 17 which meshes with an upper rack-bar b of a yoke 12 carried by a pitman b. This yoke has a longitudinal opening b in its two parallel sides, through which extends the shaft 1), the latter forming a guide and support for the yoke. The other end of the pitman h is connected to a wheel b keyed on one of the journals of the impression-cylinder'a'. On the extreme outer end of shaft 1) is a crank-arm b, which is given a back-and-forth swinging movement by the engagement of the rack-bar and toothed segment of wheel The arm I) is elongated upwardly and sustains the outer end of therest or support for a pile or stack of bags, all of which have their bottom ends folded (see Fig. 17) and resting one upon the other in such manner that one flap of this folded end will always be presented rearward away from the press. The extended arm 1) supports a rodl, to the ends of which are secured the outer ends of two parallel arms .2, the inner ends thereof supporting a transverse rod 3. The extreme top of arm I) is grooved to accommodate a horizontally-adjustable plate 4, having a longitudinal slot 5, through which extends a screw 6; With the inner end of this plate 4 is formed a perpendicular grooved plate 7, in the groove 7 of which is fitted a vertically-disposed plate 8. This plate can be adjusted on plate 7 and is held in place by any suitable means, such as a screw 8. At its lower end plate 8 supports two horizontal rods 9, forming a rest for the open ends of the bags piled or stacked in position. These rods are capable of sliding adjustment, being secured to plate 8 by a lower horizontal plate g, held by screws g. A small roller 9 is located between and supported by rods 9. This latter roller enables the body portions of the bags to be easily drawn from their support. To a cross-rod 10, supported by plate 7, are adjustably secured arms 11, which carry upright rods 12, forming guides for holding the pile or stack of bags in position. A vertically-adj ustable plate 13 is held by a block 1st, mounted centrally on rod 3. To the lower end of this plate is secured a horizontal plate 149, which supports the folded ends of the bags. Au intervening space is left between the ends of rods 9 and plate 14. The extreme ends of this plate 14: are formed into downwardlyinclined tongues 15, which serve to direct the travel of the folded ends of the bags (after being grasped by the gripper) downward toward the feed-rolls a The bags are additionally supported and guided by longitudinally-bowed plates 16, attached to blocks 17, secured on the lower ends of upright rods 18, carried by arms 19, adj ustably secured on rod 3. Blocks 17 have grooves to accommodate the rods 18, (see Fig. 9,) so that a smooth inner surface will be presented. By bowing or curving each plate 16 longitudinally of the length thereof a guide or support is provided for any depending portion of a bag, and at the same time the latter is not crowded to an extent to interfere with the feeding thereof to a press or the like.

0 is a shaft supported at its outer end by an upturned portion of arm b of frame 13, and at its inner end this shaft rests in a cylindrical bearing 0, a depending portion 0 of which is supported by frame-arm Z). (See Fig. 1.) The shaft is passed through an opening in an arm cl, extending perpendicularly from arm 11 On the outer end of this shaft is an arm d, to the upper end of which is pivotally connected one end of a link 61 and to the other end of the latter is connected one end of a second pitman cl, and also to this end of said link is connected the lower end of a second link cl. The pitman d is secured at its rear end to crank-arm 6 while the upper end of link (1" is jointed to pitman Z). The arm (Z is, as stated, perpendicular to its base and extends upwardly some distance. Against one side thereof is adj ustably held a block e, a bindingscrew 6 thereof extending through a slot 6 in said arm. This lug at one end is tapered or inclined, such taper being adjacent to the rear vertical edge of arm (Z. Against a slotted boss e of this arm, near the base thereof, is held a block E, which is capable of adjustment. This block supports a pivoted dog 0, which is normally held raised by a spring a said dog being located at about the vertical center of arm cl.

F is an arm which constitutes the carrier for feeding the bags. It is keyed at its lower end on shaft 0 and carries at its upper end a gripper designed to engage one bag at a time and feed the same forward to the feedrolls of the press. The upper end 1 of this arm is widened laterally and to the ends of said widened portion are secured parallel plates f.

The gripper is composed of an upper jaw f and a lower jaw f each being composed of two oar-blade-like plates. The plates of the upper jaw f at their inner ends are preferably integral with a hollow sleeve J, from the center of which projects an arm 1", having at its outer end trunnionsf, which loosely fit in holes in plates f. A small coil-spring f set down in a recess in arm F, presses upwardly against arm f tending to elevate the gripper. Through sleeve f' extends a shaft f on the projecting ends of which are keyed the hub ends f of the plates of the lower jaw. This shaft is capable of being partly rotated, so as to move the lower jaw toward or away from the upper jaw. To depending bosses f of the lower-jaw plates are pivotally connected rods f which are projected through openings in the lower ends of arms f, which are secured at their upper ends to the under sides of trunnions f Coil-springsf encircling these rods and bearings against armsf tend to hold the lower jaw closed against the upper jaw. From the hub end of oneof the lower-jaw plates extends a short arm f. To the outer end of this arm is pivotally connected the upper end of alink 1"", which at its lower end is connected to an arm f of a short shaft f which extends through and is supported by a hollow hub f of arm F. On the other end of this shaft is a second arm f which projects rearwardly and carries at its free end aroller f which is designed to engage the tapered end of block e. When this engagement occurs, the rocking of shaft f (as arm F is reaching the end of the forward stroke) will, through link f and arm f effect the lowering of the lower jaw away from the upper member, as against the tension of the spring f. The rod f being brought nearly into a straight line between the hinge of the lower jaw and the ends of arms f, the pressure is toward said hinge and the jaw is easily maintainedin its opened position. This avoids all binding of parts. As the lower jaw is opened by the rocking of shaft f 18 a short arm 9 on the latter is engaged by the upper shouldered end of a spring-held dog G, carried on a boss 9 of arm F, the lower end of said dog being in the form of a nose g As the arm F is moved rearward the nose 9 depresses the spring-held dog c without any other result; but as the arm F moves forward on its first short stroke the end of dog 6 being raised by its spring into the line of travel of the dog G the nose thereof will on gage said dog e and the dog G being turned on its pivot, as against its spring 9 will trip shaft f and allow the lower jaw of the gripper to close up against the upper member, grasping and holding the flap of a bag between them. In this short movement of arm F the roller f will not engage block e.

In the initial forward stroke of arm F (see Fig. 2) the upper gripper-jaw travels against the bottom of the stack of bags to a point beyond the free end of the disengaged flap of the lowermost bag or up tothe fold thereof, the spring f tending to elevate the gripper. At this point the gripper is closed, holding the flapbetween thejaws. (See Fig. This is effected by the tripping of shaft f. Then as the arm F is moved rearward a short distance the folded end or bottom of the bag is entirely disengaged from the plate 14 and in the full forward stroke of said arm as the folded end of the bag--that is, the flap thereof not engaged by the gripperspasses between and is taken up by the feed-rolls the gripper releases its hold, (see Fig. 4,) the lower jaw being opened by the 21.1'111f of shaft f engaging block 6. During this movement of the folded end of the bag and up to the time the same is securely grasped between the feedrolls the other end of said bag is supported by the rods 9, preventing it from dropping downward.

To effect the lowering of the gripper after it has grasped the bag-flap and then maintain it in a lowered position, so that it will travel on a nearly horizontal path toward the feedrolls, I provide a pitman h, pivotally connected at its upper end to a short arm h, depending from the center of the sleeve f. This pitman at its lower end is connected to an arm of a crank-shaft k mounted on a stud 7L3 on one side of arm F. The other arm of this crank-shaft has a roller 7%, which is designed to be engaged by the inclined and shouldered end it of a cam it, loose on a boss of bearing C. This cam imparts to the shaft 71 the proper movements to insure the lowering of the gripper. To an arm h of this cam is connected an adjustable rod 777, the other end thereof being connected to an arm h loose on a cross-rod h supported by arms I) and ZJXX. With arm its is designed to engage a cam h fast on shaftb, said cam having a flat surface It and a rounded surface h. A spring h on rod 71 tends to hold arm it in its normal raised position. As the cam it strikes against the arm 71 in the forward rotation of shaft 1) said arm will be depressed and through rod 72/ cam 72 is turned on its hearing, so that the incline thereof will elevate the engaged end of crank-shaft 72,27 which through pitman it will draw the gripper downward. This occurs just as the fold of the bag is being withdrawn by the'closed gripper. This lowered position is maintained by the cam h acting on crank-shaft ]L2. The cam is held depressed by rod h during nearly the full rearward stroke of armF, but. fully resumes its normal position under the tension of spring h before the short or initial forward movement of said arm, the spring f elevating the gripper against the bottom of the stack during the latter part of the full rearward stroke. The roller h during the latter part of the full rearward stroke drops to the lower portion of cam-surface 72 and as the cam is moved forward or raised at the same time that arm F makes its short forward stroke the roll 72 does not engage the surface h until arm F makes short rearward stroke after a bag is gripped, at which time cam it is again depressed by cam h engaging arm h It will be noticed that the arm F, carrying the gripper, has the following movements im- Y parted to it through the agency of the segmental wheel, the rack-bar, the pitman d arm d, and the links d d -that is to say, a bag having been delivered to the feed-rolls and the gripper-jaws opened the arm F is started on its rearward stroke. As the gripper passes beyond or is free of the flap of the lowermost bag it is raised by spring J, the cam h allowing crank-shaft k to turn. raising of the gripper against the under side of the pile occurs as the arm F approaches the limit .of its full rearward stroke. The

arm F is then given a short initiatory forward free of the forward support of the rest. Thereupon the arm F is given its full forward stroke, presenting the folded end of the bag directly in'line between the two feed-rolls. As'this occurs the gripper is opened, releasing the bag, which is fed to the press, and as the arm F starts on its rearward stroke with the gripper opened the latter is held depressed until the arm approaches the full limit of its rearward stroke, when the gripper will be raised, as before, into engagement with the under side of the now lowermost bag, and the operation is repeated as before.

Thus it will be seen that the means described impart to the arm F an irregular forward movementthat is, the arm after being moved forward a short distance sufficient to sandwich the flap of a bag between the gripper-jaws is moved rearward a short distance and then forward to the full limit of the forward or delivery stroke.

To insure the free or unsupported flap of the lowermost bag being moved away from the body portion, so as to allow the upper gripper-jaw to pass between it and the body portion,- I provide apneumatic device I. (See Figs 1 and 5.) This comprises a cylinder 1', rigidly attached to cross-rod h, and a piston 2", fitted in said cylinder and normally held raised by a coihspring 2' To a lower outlet- This opening is connected one end of a hose or tubing i which is extended so that its discharge, when the piston is depressed, will be directly against the under side of the lowermost bag on line with the end of the disengaged flap. Thus the air will force said flap downward, and as the opened jaw-gripper approaches said flap the latter will be free to be engaged thereby. To avoid confusion in the other figures in the drawings, this tube is shown only in Fig. 5, in which figure I have indicated a support for the outer end of the tube. This support comprises a rod i supported by an arm i depending from red 1. The end of the tube is extended through a sleeve *6", adjustable on rod 2' and having an upwardly-extended handle-rod 77. The pis ton is depressed by a cam J, fast on shaft 1) and so positioned that air will be ejected just as the arm F reaches the limit of its rearward stroke and preparatory to the gripper engaging the flap of the lowermost bag. The upward movement of the piston is limited by a stop-barj.

From what has been said it will be seen that I have produced simple and highly efficient mechanism for feeding bags from a pile or stack thereof to a printing or other press, one bag being fed at a time.

It will of course be understood that I do not confine myself to the construction and arrangement of parts herein described.

Various changes may be made without departing from the scope of my invention, the essential feature of which is a carrier traveling back and forth beneath a pile or stack of bags or other articles, with the lowermost member of which such carrier is designed to engage, whereby one bag or other article at a time will be freed first at one end and then mechanically fed to the press.
