Fig. 5 is a partial transverse sectional view of the clutch on the line afiar Fig. 4:. Fig. 6 is a detail of part of the controlling means, to be described; and Fig. 7 is perspective detail of the releasing mechanism for the clutch.
Referring to Fig. 1, two scoring mechanisms A and B, of usual construction, having scoring knives or cutters to cooperate with bed-rolls A and B, are shown as located at right angles to each other, a feed-table A supporting the work to be fed by an attendant sheet by sheet to the primary scoring mechanism A. The main driving-shaft A to which the bed-roll A is secured, has usual fast and loose pulleys A A and a bevel-gear a in mesh with a like gear I), fast on the shaft B of the secondary bed-roll B, to thereby rotate the bed-rolls. A suitable downhold a presses the leading edge of the sheet upon the table A as it is fed to the primary scorer, while an apron o. of usual construction directs the scored sheet to suitably-operated feed-rolls U11 whence the sheet is delivered to an intermediate table or support B and upon which it lies inert until positively fed to the secondary scorer.
Referring to Fig. 1, suitably-supported rods 2 2 above the table B support a downhold D, preferably flexible, as shown in another application, Serial No. 602,038, filed August 7, 1896, by us, and another, a third rod 3, being secured at the outer side of the table substantially parallel to the primary scorer. Upon this rod is mounted an adjustable collarl, to which is secured a stop-gage carrier 5, from which depends a stop-gage D, held in adjusted posit-ion on the rod or carrier 5 by a suitable set-screw (5,to engage the leading edge of and stop the sheet passed through the primary scorer A. As in said application the table D is grooved at Z) to receive a reciprocable cross-head b to which the cross-feed gage C is suitably secured, the cross-head having a short stroke sul'iicient to enable the feed-gage to engage one side of the scored sheet and feed it forward to the secondary scorer B.
The feed-gage C passes beneath the downhold D and is adjustable on the cross-head for sheets of different widths, and said gage is normally at rest in retracted position, as shown in Fig. 1.
A connecting rod or pitman c is pivoted at c to ears b (see dotted lines, Fig. 2) on the cross-head and depending throughthe slotted bottom of the groove 7), the other end of the rod 0 being pivotally mounted on a wrist or crank pin 0 011 a hub c, fast on a rotatable shaft O mounted in suitable bearings and 12 of the main frame.
Around the hub c we have shown a suitable adjustable friction band-brake c to hold the shaft and attached parts from accidental movement when not in operation.
Secured to the shaft B agear B is in mesh with and continuously rotates a gear 0', loose on the shaft O and forming one member of a clutch of suitable construction, the member C" having, as herein shown, an annular flange or rib on its inner face, Figs. 5 and (5, to be straddled by two lugs or projections 15 10 on a clutch-dog (I, mounted to rock in a recess (7 of the cooperating clutch member D fast on the shaft C A spring 3 normally tends to throw the dog 7) into non-radial position, Figs. 3 and 4, to lock the clutch members together and thereby effect rotation of the shaft C and consequent reciprocation of the cross-feed gage (l, but when the dog is moved into radial position against the action of the spring the lugs 15 16 release the flange 0" and disconnect the cl ntch members.
The clutch mechanism herein described is not of our invention, and no claim is herein made thereto, and if desirable other suitable clutch mechanism may be substituted therefor without departing from our invention.
Upon the main frame F is pivoted at (Z a controlling-detent (Z for the clutch, preferably having a notched end, as shown, movable into the path of and to engage the dogrl to release the clutch members and positively stop the rotative movement of the shaft C at a predetermined point, the movement of the detent being such as to allow one complete rotation of the shaft at each operation to thereby move the feed-gage C toward the secondary scorer l3 and back again to normal position. A strong spring S, fixed at one end, is secured at the other end to the detent (I to disengage it from the clutch-dog (l at the proper time, and a depending slide-rod (Z is pivoted at (7 on the detent, sliding in a bearing 0, Fig. 2. This rod, as best shown in Fig. 6, is cutaway at one side to form a shoulder (1, preferably having a slight downward incline or bevel to be engaged, when the rod is depressed as in the drawings, by a trigger f, the trigger and slide-rod being preferably made of hardened steel and polished to reduce friction. hen the trigger is set, the detent (7 is securely held in the pat-h of the dog (1 against the tension of the releasingspring S, the downward movement of the slide-rod into locking position being effected by a pin or projection on the side of the clutch member D said pin in the rotation of said member engaging a strut (1 on the slide-rod, as shown in Fig. 5. The pin reaches its lowest position after the dog (lhas passed beyond the detent (P, so that the latter is locked when the clutch has made about onehalf of a revolution.
The triggerfis fast on a rock-shaft f, Figs. 2, 3, and 7, mounted in bearings on the main frame, a springs normally turning said rock-shaft to throw its trigger into engagement with the shoulder 01 as soon as the latter is brought into position, the pin 25 releasing the slide-rod when locked by the trigger. Obviously withdrawal of the trigger from its cooperating shoulder 61 will permit the spring S to withdraw the detent from the dog d, re,- leasing the clutch, which is thrown into operation by the spring 8 of the clutch-dog. Rocking of the shaft f to withdraw the trigger is effected by very simple and strong but eX- tremely sensitive means, and by an arrangement of levers the trigger can be operated by the lightest touch, either by a sheet of paper or by the finger of the operator.
A collarf (see Fig. 7) ismounted loosely on the rock-shaft f and a hardened-steel finger f having a preferably chisel-pointed tip f, is secured to said collar, the latter being slotted at f for a pin f in the shaft, connected bya spring 8 with the finger, the spring normally holding the finger in the position shown in Figs. 3 and 7 with the side 8 of the slot against the pin f A rock-shaft g, mounted in bearings, g Fig. 2, has fast thereon a finger 9 similar to and movable in the path of the finger f the finger '9 when swung to the right, Fig. 3, engaging finger f swinging it to rock the shaft f and withdraw the trigger f from the shoulder d As the finger g completes its swing it wipes past the finger f and the spring 8 immediately is free to return the rock-shaft f to normal position, and when the finger g swings back to the left, Fig. 3, it again wipes past finger f which, with its collar f yields to permit it, the spring 5 returning finger f to operative position. A short arm g on rockshaft 9 is pivotally connected to one end of a link 9 the other end of which is pivoted to a longer arm 9 on a rock-shaft 9 mounted to rock in a stand G below the feed-table A in front of the primary scorer A. The table is slotted at A Figs. 2 and 3, to permit the passage therethrough of a controlling-arm g fast at its lower end on the rock-shaft g and preferably curved to correspond to the curvature of the bed-roll A, the downhold a being cut away at a to permit the arm 9 to swing. A spring 8, Fig. 2, returns the said controller to the position shown when free to move, the spring acting upon and through the intermediate connections described to move the finger 9 into normal position.
The various lever-arms between the finger g and the controller g so increase the power that the lightest touch upon the said controller, whether by the finger of the attendant or by the leading edge of a sheet of material, is suffieient to swing the finger g against and to move the finger f resulting in the withdrawal of the trigger f from its shoulder and unlocking the clutch-detent, so that said arm 9 acts as a controller for the feed-gage-actuating mechanism.
WVhile the actuatin g-sprin g S for the detent is a strong one, holding the shoulder d firmly against the trigger, it really requires very little power to withdraw the latter, owing to the leverages, the slight friction between the trigger and shoulder, and the downward bevel of the latter.
The controller 9 is located in front of the primary scorer, so that if moved by a sheet being fed thereto it must be engaged thereby before such sheet is at all engaged by the scoring mechanism. As the sheet is moved forward it rocks the controller in the construction herein shown toward the bed-roll, releasing the crossfeed-actuating mechanism, and the gage is moved forward and back once, the sheet maintaining the controller more or less depressed while passing over it. It matters not, however, whether the sheet is long or short, nor how long the controller is depressed, the cross-feed gage will make but one forward stroke and its return stroke before coming to rest, for after the controlling means sets the gage -actuating mechanism into motion the latter continues to operate only through one complete cycle and is automatically brought to a stop at a fixed point. Consequently the cross-feed gage may be actuated once each time the controlling means is moved into abnormal position,whether such movement is effected by the feed of a sheet to the primary scorer or by direct movement by the attendant.
The connections between the cross feed gage and the continuously-rotated shaft B including the clutch, constitute actuating mechanism for the gage, which is governed as to its operation through the clutch-detent, its locking and releasing devices by the controller, movable either manually or by a sheet as it is fed toward the primary scorer.
Our invention is not restricted to the precise details or arrangement of construction herein shown and described, for various changes may be made therein without departing from the spirit and scope of our invention.
Having fully described our invention, what we claim, and desire to secure by Letters Patent, is
1. In a paper-scoring apparatus, primary and secondary scorers, a table between them, a movable feed-gage, to feed a sheet to the secondary scorer, actuating mechanism to reciprocate said feed-gage intermittingly, and controlling means for said mechanism, out of range of the sheet to be fed by said gage and automatically operated by the initial feed of another sheet, substantially as described.
2.
