FEEDING-MACHINE AND PRINTING-PRESS CONTROLLING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 765,414, dated July 19, 1904. Application filed September 29, 1902. Serial No. 125,314. (No model.)
To all whom, it nuty concern:
Be it known that I, TALBOT O. DEXTER, a citizen of the United States, residing at Pearl River,'in the county of Rockland, State of New York, have invented certain new and useful Improvements in Feeding-Machine and Printing-Press Controlling Mechanism, of which the following is a specification.
The object of the present invention is to improve the general construction and operation of mechanism for controlling automatic feeders and printing-presses with a view to reducing to a minimum the wear and tear upon the machinery, the loss of time in printing, and the waste of paper.
In the machine of my present invention the transfer-tapes are driven from the main camshaft of the feeding-machine, which is in turn driven from a shaft operated by the printingpress, a suitable caliper-controlled clutch being interposed between the driving-shaft and cam-shaft of the feeder, so as to arrest the operation of the feeding-machine and transfertapes independently of the operation of the printing-press. I also employ side-register gages and suitable sheet-detecting devices at the front gages of the printing-press adapted to throw out the press when a sheet fails to reach registered position.
My invention consists of the general ,arrangement and combination of parts for producing the desired results, and in order that my invention may be fully understood I will first describe the same with reference to the accompanying drawings and afterward point out the novelty more particularly in the annexed claims.
In said drawings, Figure 1 is a general side elevation of parts of a printing-press and parts of an automatic paper-feeding machine arranged to feed sheets to the press and controlling devices for said machines. Fig. 2 is a detail front elevation of part of the feedingmaehine, showing particularly the calipercontrolled clutch for arresting the operation of the feeding-machine and transfer-tapes. Fig. 3 is a detail view illustrating the feederdriving mechanism. Fig. 4. is a detail elevation of one side of the forward part of the paper-feeding machine. Fig. 5 is a detail vertical longitudinal sectional view of the sheetcalipering mechanism and the feeder throwout clutch. Fig. 6 is a similar view showing the tripped position of the caliper-controlled clutch. Fig. 7 is a detail of a part of the clutch mechanism.
1 represents the frame of a printing-press in which is mounted the impression-cylinder 2 and the reciprocating bed or form 3. The impression-cylinder 2 is mounted in verticallymovable bearings 5, from which depend the rods 6, connected to a yoke 7 adjacent to their lower ends. Heavy spiral springs 8 surround the rod 6 and tend to hold the impression cylinder 2 in printing position. The yoke 7 is connected with a stationary part 9 of the press-frame by means of the toggle-links 10, to the knuckle of which is pivoted a reciprocating controller-bar 11 ,formed with a notched recess 12, in which engages a rock-arm 13, extending from a rock-shaft 14L, journaled in the press-frame. This shaft 1 1 is constantly rocked during the operation of the press for alternately moving the impression-cylinder into and out of printing position. A rockshaft 15, journaled in the machine-frame, carries a rock-arm 16, which rests directly beneath the front end of the controller-bar'll for raising said bar out of engagement with the rock-arm 13. This shaft 15 has a depending arm17, pivoted to the end of a spring-actuated rod 18, which passes through a guide 19, journaled upon the machine-frame, and carries an expansion-spring 20, confined by the adjustable collar 21. This spring-actuated rod 18 is pivoted at 25 to the throw-out disk 26, journaled to the machinerframe at 27.
This mechanism as far as described is similar in construction and operation to that shown in my Patent No. 665,072, dated January 1, 1901. Other forms of impression-cylinder throw-out mechanism may be employed.
A latch or hook 30, journaled at 31, engages a pin or lug 32, carried by the throwout disk 26, for holding the impression-cylinder tl1I'0\ -out mechanism in normal position to allow the operation of the press.
35 is a trip-rod journaled to the hook 30 at 36 and provided at its upper end with a step 37.
4:0 is a feed-board of ordinary construction suitably mounted in proper relation to the impression-cylinder 2 of the printingpress.
Projecting forwardly from. the inner end of the feed-board L0 are the usual under-guide fingers 41, which will be hereinafter more fully referred to. A series of transfer conveyer bands or tapes 15, passing over a roller 46, suitably journaled above the upper face of the feed-board 40, are arranged to convey successive sheets of paper from the automatic feeding-machine to the printing-press. These bands or tapes deposit the sheet upon the feed-board with its forward edge in contact with the printing-press front guides in readiness for the operation of the side-registering mechanism. This latter mechanism will now be described.
tering mechanism forms no part of the present invention, and any suitable side-registermg mechanism may be employed in combination with the other devices hereinafter re For the purpose of illustrating ferred to. the invention I have shown in the drawings and will now describe in a general way the side-registering mechanism covered by my Patent No. 669,72 granted March 12, 1901, for improvements in sheet-conveyer frames.
The mechanism set forth in this patent comprises two laterally-operating paper-shifting ing devices. is one of the reciprocating transverse bars, having a spring for moving:
it inwardly and supported in suitable guides on the brackets D. The outward movement of the bar 2' is effected by means of a longitudinally-movable cam-platej, mounted in suitable guides on the bracket D. The camplate j is adapted to engage a roller (not shown) carried by the bar 5 for moving the bar 4) outwardly. A rod R is connected with the cam-plate j and reciprocated by any suitable cam mechanism, which may be operated from the feeding-machine, as hereinafter explained. The gripper-fingerfnot shown) is fastened to a transverse shaft N, suitably journaled in brackets mounted upon the bar To the other end of the-shaft N is rigidly secured a radially-projecting lug m, and in front and rear of said portion of said shaft are posts on, projecting up from the face of the cam-plate j, to which are adjustably connected studs or tappets m disposed to strike the lug m alternately upon opposite sides dur-. ing the reciprocating movement of the camplate 1'. The operation of this side-registering mechanism will be clearly understood 211T. ter referring to the above-named Patent No. ($69,724:, the corresponding parts of the structure being indicated in the present case by the same reference characters that are used in said patent.
is a controller rock-shaft suitably journaled in the machine-frame and carrying a rock-arm 61, which is connected, through a down wardly-projecting link 62, with the hook or latch 30 of the impression-cylinder throwout mechanism above described.
is the main switch-lever pivoted at 66 and controlling the contacts (indicated at 67) which are included in the electric circuit which supplies current to the motor which operates the printing-press. In place of the switch-lever 65 a belt-shifting lever may be used when the press is operated by steam. The specific construction of the side-regis-,
A rock-arm 70 depends from the rock-shaft 60 just behind the switch-lever 65, so as to open the switch when shaft 60 is rocked.
The specific form of the controlling mechanism just described is immaterial to the present invention, and, in fact, it is not essential whether the controlling mechanism is electrical or mechanical.
A rock-arm projects upwardly from the rock-shaft 60 and has pivoted at its upper end 76a link 7 7 which is pivotally connected at 78 to a rock-arm 79, journaled at 80 to the bracket D. Projecting forwardly from the rock-arm 79 is a rod 85, which is journaled to the rock-arm at 86 and carries an adj ustable block or tappet 87, formed with a rear curved or cam face 87 and secured in the desired adjusted position upon the rod by any suitable means, such as a set-screw 88.
The rod 85 is controlled by the mechanism presently to be described. When the rod is in its lowermost position and the cam-plate y' is moved rearwardly, a part 90, projecting from the forward post 122/, will engage the tappet 87, forcing the rock-arm 79 rearwardly to operate the controller-shaft 60 and cause it to break the electric circuit and actuate the impression cylinder throw out mechanism. If, on the other hand, the rod 85 is in its raised position, the tappet 87 will not be engaged by the part 90, and the controlling mechanism will therefore not be operated. A stud 95 is adjustably mounted on a stationary part of the frame to one side of the line of travel of part 90 and in the path of tappet 87. WVhen the tappet 87, engaged by part 90, is forced rearwardly for operating the throw-out mechanism, the cam-face 87 engages stud and lifts the tappet 87 out of engagement with the part 90, thereby stopping the movement of rod 85 and allowing cam-plate j to complete its stroke.
is a rock-shaft journaled in a bracket 101 and carrying a finger 102, which rests directly beneath the forward portion of the rod 85. The rock-shaft 100 also carries an arm 103, formed with a lateral slot 104, in which is adjustably mounted a pin 105, carried by a link 106. The pin 105 can be clamped in any desired adjusted position upon arm 103.
The link 106 is formed at its opposite end with an elongated slotted yoke 107, in the slot of which engages a pin or stud 108, mounted upon the rear post an of the cam-plate j.
110 is a forked or bifurcated arm mounted upon the rock-shaft 100 and straddling the rod for holding it against lateral displacement. Aspiral spring (not shown) surrounds the rock-shaft and tends to rotate shaft 100 to throw the finger 102 into engagement with rod 85 for raising the rod and holding the tappet 87 out of the path of the post m.
represents the front guides-of the printing-press, adjustably mounted upon the arms 121, which are secured upon a rock-shaft operated, as usual, by the press. Each front guide has projected from its sheet-engaging face a plate 125, formed with an upturned end This plate 125 rests above and parallel with the under guides 41 of the feed-board when the front guides are down in operative position for the purpose of confining the forward edge of the sheet between the under guide and the plate to prevent the sheet from buckling at its forward edge.
is a tripping-plate pivoted to the face of each front guide 120 and formed with a bifurcated lower end, the legs of which straddle the plate 125 and the under-guide finger 41.
Formed integral with and projecting rearwardly and laterally from the plate 130 is an arm or dog.131. A counterbalance-weight is attached to the rear face of the plate 130 for holding the plate 130 and attached arm 131 in normal operative position.
Rock-shaft 100 carries a depending rockarm 140, to the lower end of which is pivoted a reciprocatory rod 141, which rests and slides in a notch cut in the upper edge of the front guide 120. This rod 141 is formed on its lower face with a shoulder 143, which is adapted under certain circumstances to engage the arm or dog 131 of the sheet-actuated trippingplate 130.
When the sheet is fed to the press by the automatic feeding-machine, its forward edge comes in contact with the front guides of the press and is arrested in this position. After the sheet reaches the proper registered position against the front guides it will be clearthat the tripping-plates 130 will be pushed gripper laterally to register the sheet, and at the end of this stroke the stud 108 will engage the outer end of the slot in the yoke 107 I as of rod 106 to rock the shaft 100 against the action of its spring to depress the finger 102 and throw rearwardly the rod 141 in readiness for the operation upon a second sheet. If the sheet fails to reach the proper position against the front guides 120, the arms ordogs 131 will not be depressed, and upon the return of the cam-plate 7" one of said dogs 131 will engage shoulder 143 on the rod 141 and prevent the spring moving the shaft 100 back to raise the finger 102. The result of this will be that the rod 85 will remain in its lowered position and the tappet 87 will rest in the path of the part 90 on post m, so that when the'cam-plate returns to register the sheet laterally the rod 85 will be forced rearwardly, causing the arm 79 to rock upon its bearing and move the controller-shaft 60 upon its bearing, with the result that the circuit will be broken at contacts 67 and the machine will be thrown out of operation, as above explained.
A horizontal shaft-section is driven from a part of the printing-press through sprocket-wheels 151 152 and chain 153 and bevel-gears 154 155. This shaft-section 150 has a universal-joint connection with a central horizontally-extending shaft-section 165, which in turn is connected by universal joint 166 with a shaft-section 167, carrying a beveled gear 168, which meshes with the gear 169 on the vertically-extending feeder-operating shaft 170. The upper end of this shaft 170 carries a beveled gear 171, meshing with a similar gear 172, journaled on a stud 173 of hook 182, having a rearwardly-extending heel or finger 183, to which is pivoted a springactuated rod 184, which passes through a guide-nut mounted upon the disk 180.
The hook of the curved arm 182 normally engages a pin or lug 186, carried on an arm 187, which is keyed to the cam-shaft 176. The engagement of the hooked arm 182 with thelug 186 causes the shaft 176 to rotate with the disk 180. All of the parts of the feeding-machine are operated from shaft 17 6. The arm 182 also has a laterally-projecting pin or lug 190, which is adapted to engage the inclined face of a cam-block 195 when the latter is moved laterally into the path of said lug 190. This cam-block 195 slides in a suitable bracket 197 and has projecting from' it the pin 198, formed with a slot 199, in which engages the segment-cam 200, mounted on the rock-arm 201, keyed to the throw-out rockshaft 202.
210 is the throw-out controlling-cam of the caliper-controlled mechanism. This cam 210 is keyed to the main cam-shaft 176 of the feeder and is formed with a low portion 210, the purpose of which will presently appear.
A rock-arm 215 is keyed to'the rock-shaft 202 and carries adjacent to its forward end an antifriction-roller 216, which operates upon the periphery of the controlling-cam 210. This rock-arm 215 is also formed with a forwardly-projecting nose 217, which normally rests above the upper end of apendulum-lever 220, which is journaled to the machine-frame at 221. This pendulum-lever is operated by the sheet-calipering device, which will now be explained.
230 is a roller keyed to a constantly-driven shaft 231 on the feeding-machine.- This roller 230 constitutes the lower member of the sheetcalipering device.
235 is a rock-arm journaled to the machineframe at 236 and carrying the normally stationary rotatable calipering-wheel 237 which is journaled to said rock-arm at 238 and has projecting from one face a pin or lug 239. An arm 240 projects downwardly from the jour-- nal 221 of the pendulum-lever 220 and is connected with said pendulum-lever. Arm 2 10 rests behind the lug 239.
245 is an adjustable limiting-screw threaded through a lug 246 on rock-arm 235 and engaging a rigid lug 2&7 on the machine-frame. By adjusting the screw 2 15 the relation of the upper calipering member 237 to the lower calipering member 230 may be regulated to a nicety. A spring-actuated rod 250 is connected to the free end of the calipering supporting-arm 235 for holding it downwardly with a yielding pressure. If an extra thickness of sheets passes between the caliperingwheels 230 and 237, the wheel 237 will be rotated by rock-lever 220 to move it from beneath the nose 217 of rock-arm 215. This will remove the support for said rock-arm when the low portion 210 of cam 210 reaches the antifriction-roller 216, and hence the rockarm 215 will drop, causing the shaft 202 to be rocked for throwing out the clutch above de- 1 scribed. The disengagement of the clutch effects the disconnection of the feeding-machine from the driving-shaft operated by the printing-press.
The transfer-conveyer bands or tapes 45 are passed over the feed-board of the printingpress and are supported at their forward end upon the tape-roller 4:6 and supported at rear upon a driving tape-roller 275, having at one end a gear-wheel 27 6, which is driven through the intermediate gears 277 and 278 from the gear 279, keyed to the main cam-shaft 176 of the feeding-machine. It will be observed that the gear 279 is at the opposite end of shaft 176 from the driving-clutch above described. From this arrangement itwill be observed that the transfer-tapes being driven by the feeder cam-shaft will be under direct control of the feeder throw-out mechanism, so that the said tapes will stop when the feeding-machine stops.
The rod R, which operates the side registering mechanism above described, extends from the said mechanism to the adjacent end of the feeding-machine, where it is connected at 285 with the lower end of a lever 286, journaled to the feeding-machine frame at 287. The upper end of the lever 286 carries an antifriction-roller 289, which operates upon the periphery of a cam 290, which is adjustably secured to the face of the gear 175 above referred to.
When the machine is started, it will be observed that the automatic feeding-machine driven through the mechanism described will feed the successive sheets of paper to the transfer-tapes, which in turn carry the sheets down to the front guides of the printing-press. WVhen the sheet reaches the front guides of the press, it is registered in the manner already described. If the sheet-calipering device detects an extra thickness of sheets, as in the case of two sheets being fed forward from the feeding-machine, the feed-clutch will immediately bethrowuout to arrest the operation of the feeder and transfer-tapes. This will arrest the forward movement of any sheets which happen to be on the transfer-tapes on their way to the printing-press. The printing-press being under control of its independent sheet-actuated tripping devices will continue to operate upon any sheet which has reached the front guideor has gone part way throught-he press; but immediately after the passage of any sheet which has started through the printing-press themovement of the presswill be arrested. The im portance of this arrangement is the fact that the press is not stopped until the completion of an operation upon any sheet which happens to have reached the press, so that there is no danger of destroying any sheets of paper. It makes no difference whether the press throw-out mechanism fails to arrest the movement of the operating parts of the press instantly after it is tripped, since no more sheets can go intothe press and no harm can be done.
I would have it understood that the construction illustrated and described in my 1. The combination of a printing-press, a
