SPECIFLCATION forming part of Letters Patenty No. 699,913, dated May 13, 1902.
Application filed May 23, 1901. Serial No. 61.488. (No model.)
This invention relates to the class of devices appliedA toprintifng-presses for automatically arresting the actionl of said presses in case of defect in the feeding; of the paper to the press; and the .invention pertains more particularly to the Aautor'naticv controller for printing-presses shown in my Letters Patent No. 665,072, dated Januaryll, `1901.
The object ofmypresent 4invention is to simplify the construetiouof the mechanism of the automatic controller and at the vsame time obtain greater convenience and efficiencyV of operation; and to that end the invention consists in the improved construction and combination of parts hereinafter described, and summed upyinthe claims. n
In the annexed drawings, Figures l and 2 are side elevations of a printing-pressand feeding-machine equipped with my invention shown in its different operative positions. Fig.- 3 is a plan view of the same. Fig. et is au enlarged side view of the stop mechanism. Fig. 5 is an enlarged section on line x in Fig. 2. Figs. 6 and 7 are side views of a modification of the stop mechanism shown in different operative positions. Fig. 8 is a plan view of said modification. Fig. 9 is a vertical section on line y yin Fig. 8. Fig. lO is an enlarged side view ofthe cast-off mechanism. Fig. 11 is a transverse section on line ,z a' in Fig. 10, and Figs. 12 and 13 are detached side views of the two disks forming part of the cast-offmechanism.
ySimilar letters of reference indicate correspondingparts. v
A represents the printing-press of the class termed two-revolution presses.
B represents an automatic paper-supplier or paper-feeding machine which may be of any suitable and well-known construction.
C denotes the feed-board, uponwhich the paper is cond cted from the feeding-machine tothe printing-press.
l) and D represent the loose pulley and tight pulley, mountedon the driving-shaft, from which'motion istransmitted to the press mechanism by meansof suitable gears in the usual manner and as indicated by dotted lines in Figs. l and 2 of the drawings.
F is the driving-belt, and F' is the lever by means of which said belt can be shifted from one to the other of said pulleys for starting or stopping the press.
G represents the ily-wheel, which is fastened to the shaft ofthe aforesaid pulleys.
I and I are shafts supported in suitable bearings a a and a o.' on the frame H and H of the press and feeding-machine. By means ofmiter-gears on said shafts and suitable gears oufthe press and feeding-machine said machineis caused to operate in unison with `the press.
'transverse shaft o', pivotally connected at its ends to the toggle-'levers cwhieh are arranged at opposite sides of the press, to lift the impression-cylinder of the two-revolution press at ,regular intervals of time in the usual and well-known manner. (See Figs. 4 and 5 of the drawings.) Said rod receives motion from a rock-arm d, engaging a notch d in the under side of the rod. Said notch allows the rod to be 'lifted out of engagement with the rockarm when desired to trip the impressioncylinder from its operative position. The lifting of the rod cis usually effected by a treadle e, securedto the upper end` of a vertical stem e' and in a convenient position to be operated by the foot of the pressman standing on the usual footboard L on the side of the pressframe. ally connected to the ou ter end of a lever fulcrumed ou the press -frame and extending with its inner end under the rod c. ver, however, is dispensed with by my pres- The lower end of said stem is usup This le- ICO said lifting of the rod c, as Well as the shifting of the belt F to the loose pulley, said invention consisting, essentially, in the combination, with a printing-press and its actuating meehanism,of stop mechanism actuated to automatically arrest the action of the press, a movable detent normally disposed to restrain said stop mechanism, a east-od mechanism for throwing said detent from its normal position, a guard movable to and from a position to restrain said cast-off mechanism, and a feeler actuated by the paper in transit to the press and controlling said guard.
The aforesaid stop mechanism consists of a pivoted tripper which is suitably connected to the actuating mechanism to control the same and may be either of the form of disks T and T', pivoted at their centers to a stud s, projecting horizontally from the side of the press-frame, as shown in Figs. 4 and 5 of the drawings, or of the form of an approximately horizontal lever T2, pivoted intermediate its ends on the aforesaid stud, as represented in Figs. G and 7 of the drawings. Vhen of the form of a disk, as aforesaid, the connection with the actuating mechanism is made by means of a rodf, which is connected at one end eccentric to the disk and has its opposite end connected by a chain f3 to one of the arms of a hell-crank f, pivoted to a suitable stationary support. The other arm of said bell-crank is connected to a horizontal eXtension F2 of the foot of the belt-shifting lever F'. A chain or rod f' is connected at one end to the rod f and at the opposite end to a lever f2, pivoted at one end to a suitable stationary bracket and carrying on its free end the brake b. A spring-actuated push-rod 7L is suitably supported at one end on the pressframe and connected at the opposite end to the disk T at a point approximately diametrically opposite the attachment of the rod f. Said rod 7L forces the disk to turn in a direction which causes the rodf to draw the belt F onto the loose pulley by means of the bell-crank g and at the same time actuates the lever]C2 to apply the brake b to the fly-wheel G. When the aforesaid tripper is of the form of the lever T2, as shown in Figs. 6 and 7 of the drawings, the shorter end of saidlever is connected by either a chain or a rod f' to one of the arms of a bell-crank h2, whose other arm is connected to the rod f. A weight V, connected to the opposite end of the lever T2, causes said lever to draw the rodf in the requisite direction to shift the belt and apply the brake, as aforesaid. The movable detent, which is normally disposed to restrain said stop mechanism, I prefer to form of a latch i, which is pivoted at one end to the side of the press-frame or to a plate P, attached to said frame. The free end of said latch is formed with a vertical offset or shoulder by which it engages a lug t" on the disk T or an arm i2 on the lever T2, according to the shape of the aforesaid tripper. The aforesaid engagement of the detent or latch i restrains the tripper T or T2 from shift-ing the belt F onto the loose pulley.
For automatically tripping the impressioncylinder of a two-revolution press I mount on the stud s a second revoluble disk T', as shown in Fig. 5 of the drawings, or a second lever T3, as represented in Fig. 8. Said disk or lever is actuated by a spring-actuated rod j or a weighty" and is restrained from acting by a detent or latch l7'2 iu substantially the same manner as the disk T and lever T2, hereinbefore described.
To automatically lift the press-tripping rod o by means of the disk T', I Vmount in suitable bearings on the press-frame a horizontal transverse shaft 7o, to which I attach an arm 7c', provided on its free end with a roller by which it bears on the under side of the rod c. To the outer end of the shaft I fasten an arm 7a2, the free end of which is connectedby a rod k3 to a stud k1, projecting from the side of the disk T'. When this disk is released from the detentj2 and turned by force of the spring-actuated rod, the rod k3 is caused to turn the shaft 7a by means of the arm 7a2. Said movement of the shaft causes the other arm 7;' to lift the press-tripping rod c, and thus trip the impression cylinder. Vhen said tripping is to be effected by means of the lever T3, as shown in Figs. 8 and 9 of the drawings, I connect said lever by a rod N to the free end of an arm N', fastened to a transverse shaft N2, to the inner end of which is attached a second arm O, provided on its free end with a roller which bears on the under side of the press-tripping rod c.
The east-off mechanism for throwing ,the detents e' and y2 from their normal position or out of engagement with the 'tripper-disks T T' or tripper-levers T2 T3 consists of two disks H', pivoted on a stud-pin Z2, projecting horizontally from a plate Z3, fastened to the side of the upper part of the press-frame, preferably in proximity to the feed-board. To the side of the disk Z, at a point eccentric to the pivot thereof, is connected the upper end of a chain m or other suitable coupling, the lower end of which has extending from it two branches 'm' m', which are connected to the free ends of the latches fi andj. disk Z is provided with a notch or shoulder n,
IOO
The periphery of the suitably shaped to allow it to be engaged by a pawl n', pivoted to the end of a lever o, which is mounted at or near the center of its length on the stud-pin Z2 and has its' opposite end connected to the end of a rod o', Whose opposite end is connected to one end of a lever p, which is pivoted intermediateits ends to a suitable bearing on the frame of the feedingmachine B and is provided on its opposite end with a roller, which rides on the face of a rotary cam p', supported on the aforesaid frame. Said cam receives motion from the actuating mechanism of the feeding-machine by any suitable means. (Not necessary to be shown.) A spring-actuated rod p2, connected to the leverp, maintainssaid leverin Contact with the cam p, which imparts oscillatory motion to the lever p. The rod'o transmits said motion to the lever o, which by the en-l gagement of its pawl ln turns the disk Z part way on its pivot. The turning of this disk causes the detents or latches U2 to be lifted out of engagement with the tripper-disks or tripper-levers by means of the chain m. This release of said disks or levers allows them to automatically shift thebelt to the loose pnlley and also trip the impression-cylinder. To automatically control this stop mechanism, I employ a rock-shaft r, which extends across the feed-board adjacent to the impression-cylinder and is mounted at its ends inI suitable brackets r', secured to the feed-board or to a sheet-conveyer frame resting on the feedboard. To said rock-shaft are fastened forwardly-projecting arms r2, directly under the free ends of which are feelers Z, pivoted on a transverse rod 1V, which is supported at its ends on arms formed on the brackets r. Said feelers normally rest with their lower ends on tongues w, which project from the end of the feed-board. The' feelers are thus in position to be tilted by the paper in transit from the feeding machine to the press. When the feelers are in said position, the arms r2 of the rock-shaft#l come in contact with the tops of the feelers, and thereby arrest the action of said rock-shaft. To the end of this shaft is attached an arm c, the free endV of which is connected by a rod u to a stud-pin fu', projecting from the side of the disk Z', pivotally supported on the stud-pin Z2, as hereinbefore described. This disk receives oscillatory motion from a rotary cam R,disposed at the side of the cam p on the feeding-machine and imparting oscillatory motion to a leverR, from whence motion is transmitted tothe disk Z by a connecting-rod u. The motion of said disk imparts rocking motion to the shaft r by means of the rod u. The periphery of the disk Z has projecting from it a guard of the form of a cam Z2, which during the oscillation of said disk is carried intermittently'to a position to pass under a projection on the pawl n', and thereby lift said pawl, so as to prevent it from engaging the notch or shoulder n on the disk Z, which is thus left in a dormant position and free to allow the detents orlatches i j to drop into engagement with the tripper-disks T T or tripper-levers T2 T3, and thereby prevent interruption of the action of the press. The aforesaid guard or cam Z3 is allowed to be carried into the position to prevent engagement of the pawl n with the notch or shoulder n so long as the paper passes to the press and tilts the feelers Z, so as to allow free movement of ythe rock-shaft r and guard-disk Z; but whenever either of the feelers fails to be actuatedby a sheet and is thus allowed to remain in normal position the motion of the rock-shaftvis arrested by the armo"2 coming incontact with the upper end of the dormant feeler. The rock-shaft is thereby retained in a position which causes the connecting-rod u to lock the guard-disk Z and prevent it from lifting the pawl 'n' out of engagementwith the notch or shoulder n on the disk Z, which is thus allowed to be turned by the lever o and in this movement lift the detents or latches j out of engagement with-the tripper disks or levers, which then automatically shift the belt onto `the loose pulley and trip the impression-cylinder. Hence the actuating mechanisms of the press are controlled automatically by the feelers actuated by the paper in transit to the press. The two cams R and p should be set in such position in relation to each other as to cause the guarddisk Z/ to turn forward slightlyi'n advance of the forward movement of the pawl n', and thus insure the lift of said pawl before its arrival at the shoulder n of the disk Z.
To allow the operator to again set the press in motion after it has been automatically arrested, as herein described, I employ the chain f3 or other suitable flexible connection between the tripper and belt-shifting lever to allow the brake to be removed from the ily-wheel without exerting any stress on the belt-shifting lever, which can then be operated by han'd to throw the belt onto the driving-pulley ywithout any restraint from the brake. The brake is thrown from the liy-wheel by the operator depressing the treadle e, the stem e of which is connected to the arms e2, fastened yto the sides of the tripper-disks TT', as more` clearly shown in Figs. 4 and 5 of the drawings. Said depressing of the treadle turns .the tripper-disks back to a position to allow the latches ij to rengage said disks and simultaneously pushes the brake from the'flywheel., When the aforesaid trippers consist :of levers T2 T3, I pivotally connect said treadle to the ends of the shorter arms of the said leyers, asshownjin Figs. 6, 7, 8, and 9 ofthe drawings. A pressure appliedtothe treadle 'e by thefoot of the pressman restores thetripper-levers to a position to allow the latches t' j to rengage said disks or levers, as aforesaid.
What I claim as my invention is- 1. In combination withaprinting-press and feeder, the automatic stop mechanism, a tripper controlling said stop'mechanism, and a detent movable to and from apposition to restrain the action of the tripper, two disks disposed side by side and oscillating independently of each other, means for transmitting motion yfrom one of said disks to the aforesaid detcnt, a guard carried on the other of said disks to and from a position to prevent transmission of motion to the detent, and a feeler actuated by the paper in transit to the press and controlling the motion of the guard-carrying disk.
