Specification of Letters Patent.

Patented June s, 1909.

Application ied'Juiy 1e, 190s. seal No. 443,780.

To all whom it may concern:

Be it known that I, CAsiMievoN IHiLr, a citizen of the United States, and a resident of the borough of Brooklyn,county of Kings, f

city and State' of New York, have invented `certain new and useful Improvements' in Feeding Mechanism, of which the following is a speciiication accompanied by drawings. This invention relates to special printing presses' printing on a continuous web .of

paper, and the objects of the invention are to improve -upon the construction of the feeding mechanism for such presses, enable close register with high speed to be obtained, and prevent backward movement of the feed drum as the drum is brought to rest interinittently. Further objects of the invention will hereinafter appear, andthe invention embodies the features of construction,,combinations of elements, and arrangement of parts substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which- Figure l is a front end elevation of the feeding mechanism; Fig. 2 is a rear end elevation; Fig. 3 is a plan view; Fig. 4 is a transveA ie sectional elevation on the line m,

of Fig. 3, looking in the direction of they arrows; Fig. 5 is an enlarged detail Aview of the ratchet and pawl device; and Fig. 6 is a side elevation o f a portion of the machine embodying the feeding mechanism, and the means for feeding the separating sheets between the printed sheets.

In the general assembly view, Fig. 6,' A represents the frame of the press, and rB is the feeding` head or mechanism forming the subject matter of this invention. C is a heavy punching head, D is a light punching yhead or shear, which may be inthe form of a. perforating head. E is a multi cutting off 'extending transversely and supported in suitable bearings in the` device. F are auxiliary feed rolls, and G is the slip sheeting device. The parts C, D and E are merely shown diagrammatically, as they form no part of the present invention. The feed head B is longitudinally movable on the frame A or bed of the m'achine, and power is transmitted to said head through the shaft I and bevel gears J and K. Bevel gear K is carried on the shaft L of the feeding head frame O of said head. On thefother end of the shaft L is a crank disk P connected to intermittently actuate the feed drum Q. The

' of the shaft, R is actuated from the feed drums through suitable gearing, and the pressure rollsS coperate with said drum. The feed-,

h lg head is also provided with suitable devices for treating the paper, as the rulingrolls T, perforating rolls U, creasing rolls V, and slitters W connected to be actuated by suitable trains of mechanisms. The web of paper is fed along the paper line in the direction indicated by the arrow on said line. The disk P is crank pin a adapted to be moved radially by means of the screw b. The rod c connects the pin a with the pin a'- on a vertically movable rack e which is thereby vertically reciprocated Mesliing with the rack is a inloosely on the trunnion g o the Connected to the pinion f is ion f turnin feed drum an arm L, and a ratchet wheel z is keyed to the trunnion g. At the other side of the provided with the adjustable A ratchet wheel is an arm j turning loosely on i the hub of the wheel.

to coperate with the ratchet wheel z' and carry said ratchet wheel forward on the up;

Pivoted to the arms. /1- and y' 1s a. spring pressed pawl l.: adapted.

positively retarding the feed drum at the end of each intermittent and this brake is automatically released at intermediate intervals. Secured to the trunnion o of the feed drum Q is a brake pulley p provided with a divided brake shoe Q bolted together by means of the bolt r and having one section secured to the frame of the feeding head by the pin s. The sections brake shoe are normally pressed toward each other by the spring t on the bolt a, but held apart by the squared portion v of the pin w shoe. the pin w by means of the bolt y to enable the throw of the lever to be varied and thus vary the brake pressure. The lever 1s provided with a roller .a at its outer end bearing Aupon the cam 2 when the roller a is on the high portion of the cam 2, the squared portion@ of the pin fw is carried into such position that the shoe is inserted between the ends of thc` A levert@ is adjustably clamped toforward rotation,

adjustably secured i to the shaft L by means of the adjustingbe changed, inorder with this construction,

loosened on the brake pulley p. As soon, however,

as the roller .e drops to the low por- 'tion of the cam 2, the squared portion of the and retard the feed drum at the exact point desired. The brake is then released as the roller e rises on the high portion of the cam 2. lThe intermittent motion of the feed drum and the operation of thebrake are so timed that the feed drum isretarded automatically at the end of each forward movement.

Atoothed ,feeding devicesL is pivoted on thepin-fa to the'frame of the feeding head and' connected-to be actuated at its lower end by means of the stop 5 on the eccentric rod 6 carried by the eccentric strap 7 connected to the eccentric 8 on the shaft L. Between the fixed nut 9 and loose nut 10, is a spring 11, which. tends to press the lower end of the toothed stop 4 in a direction to bring the toothed end 12 of the device into engagement with the teeth of the disk 13 fixed to the trunnion 0 of the feed drum, thereby positively feeding and stopping the `drum at the end of each intermittent for- @wardmovement As the eccentric 8 revolves, *the stop. 5 carries the lower end of the .vt othed device upwardly to release the disk 1 The `peculiar construction of the teeth ltlefdisk 13y and the teeth 15 of. toothed device 12 is designed to prevent any slight backward'movement of the drum at the instant that it is stopped.

As shown, the teeth 14 slope in one direction only, thatis, backward or in the oppositedirection to th movement of the disk 13. The teeth 15 correspond to the teeth 14., so that the disk 13 is always moved forward as the toothed feeding device 12 moves into engagement with the disk 13. Y

ln the operation of the feeding mechanism, the brake and the toothed feeding device are normally disengaged. At the end of the stroke, the brake is first brought into action to retard the motion of the drum and bring it to a stop and the operation is so.

timed that the toothed feeding device 12 then enga es the disk 13 and finishes the final smal feeding movement of the stroke. The toothed feeding device and the brake are both disengaged before the neXt stroke.

Connected to the trunnion o of the feed drum Q is a gear 16 meshing with a pinion. 17 on shaft R for driving I the pressure wheels S. The shaft R is carried in adjustable bearings 18, having springs19 and ad- .justing screws 20.

The ruling, perforating, creasing and slitting devices are actuated from the gear 21 these shafts are supported on adjustableV bearings having the adjustable screws 26.

I claim and desire to obtain by Letters f Patent the following:

1. In a feeding head, the combination of a feed drum, means for intermittently rotating the same, a toothed wheel connected to said drum having teeth inclined in the opposite direction to the direction of movementof the wheel, Vand a toothed feeding device having teeth cooperating with those 'on the wheel,'whereby engagement of the feeding device with the wheel will always tend to move the wheel and drum in the direction of rotation. i l

2. In a feeding' head, the combination of a frame, a feed drum mounted therein, means connected to the drum for imparting an inY termittent rotation to the same, a brake pulley connected to the drum, a brake shoe comprising two members, one member being connected to the frame, a pin having a squared head mounted between the ends of said members, a rocking Alever adjustably connected to rotate said pin, and an adjustable cam controlling said lever. l

3. ln a feeding head, the combination of a frame, a feed drum mounted therein, means t connected to the drum for imparting an intermittent rotation to the same, a brake pulley connected to the drum, a brake slice comprising two members, one member being connected to the frame, a pin having a squared head mounted between the ends of said members, a rocking lever adjustably connected to rotate vsaid pin, and an adjustable cam controlling said lever.

fi. In a feeding head, the combination of a feed drum, means for intermittently rotating the same, a brake for the drum, means for automatically applying the brake at the end of the stroke of the drum and releasing the brake thereafter, a positive feeding device for the drinn, and means for automatically applying the feeding` device at the end of the stroke of the drum and releasing the feeding device thereafter.

In testimony whereof I have signed this 'specification in the presence of two subscribing witnesses, July l0, 1908.
