Specification of Letters Patent' watentedaritdhlth.
Application filed March 15, 1909. Serial No. 493,578.
To all whom it may concern:
Be it known that ll, HENRY-F. BEGHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements 1n Stereotype-Plate Boring and Cutting Ma chines; and I hereby declare that the rjollowing is a full, clear, and exact description thereof, reference being had to the accomfiled March 15, 1909." Such plates are sub stantially tubular in form and are preferabl but one page in width and one pagein ength and are adapted to substantially surround the entire circumference of the plate cylinder in the press, which cylinders are of very small diameter. It is necessary that such single page tubular plates should fit accurately upon such plate cylinders, and should be trimmed to exact length; andthe objects of the present invention are to bore such plate, or dress it internally, to the exact diameter. requisite to cause it to fit snugly on the plate cylinder; to cut oil the I head of metal formed on one end of the plate in the casting operation; and to trim such end of the plate accurately so that when the plate is put on the cylinder it can be readily securedin correct position, and will print uniformly on the web. I
The present invention therefor embodies novel. means for holding and rotating the plate while'being bored and trimmed; novel tit means for operating the boring tools; and novel means 'for'cutting thesurplus metal head oil of the plate, and for trimmingand beveling its. end.
In the accompanying drawings T have illustrated a machine embodyingthese features, and-the description of such machine will impart a clear understanding of the in vention, and the claims summarize the invention and featuresthereof for which protection is desired.
Tn said drawingsl igure 1 is a front elevation of the machine showing a plate: in
position for trimming. Fig. 2 is a plan view-of Fig. 1. 'Fig. 3 is a transverse section on line 3-3, Fig. 2. 4 is a longitudinal section on line 4-4;, ig'.'2, transverse section on line 5-5, lfig. 2. Fig. dis a detail view of one of the clutch memhere. Fig. 7 is a transverse section on line 7,7, .Fi'g. 2. h Fig. 8 is a plan view of the longitudinal rib'detached. Figs. 9 and 10 65,
areldetail views of the cutting and trimming too V Mounted on a supporting frame or table 1 of any suitable. form are a pair of axiallyalined bearings 2, in which is rotatably 1ournaled a hollow cylinder, or tubular plate holder 3,. whose internal diameter is exactly equal to the external diameter of the finishedtubular stereotype plate, when fitted on the cylinder, andv whose length is slightly less than the length of such plate. The bearings 2- may conveniently be cast integral with a base plate 2 so that they can be readily fastened to the frame 1.
On one end of the cylinder or plate-holder 3 is a gear 3 which meshes with a pinion 4: on a shaft 4:- journaled in a, bracket 1 attached to the frame 1, the shaft 4 lying at one side of theaxis of thesleeve and parallel therewith; and pinion 4 on shaft 4 in turnmeshes with a pinion 5 on a shaft 5 journaled. in a bracket l attached to the frame 1; shaft 5 lying parallel with the plate-holder 3, at one side 01'' thebearings 2. Shaft 5 is provided'with a pulley 5 which can be'belted to any suitable driver. In this manner the plate-holder 3 can be rotated in the bearings 2.
The plate-holder 3 is provided with a longitudinal rib 3 on its inner face,- said rib forming an abutment for one edge of a tubular plate P when the latter is inserted in. the plate-holder, as shown. This plate P as will be seen by reference to Fig. 3 is tubular, but has a narrow longitudinal slot 7) .at one side which equals the distance between consecutive impressions to be made on the Web. When a plate P is placed in the cylinder-its slot 79 registers with the rib 3".
lPivoted on tl1e plate-h0lder 3 interme- 103 diate the bearings 2, are two plate clamps, which as shown are preferably shaped like bell-crank levers, whose short arms 3 projectthrough slots in the sleeve and lie in n tches in the bar 3",- While their outer arms Fig. 5 is a 60 arms 3 and lie close the plate-holder. These clamps havetrunnioiis fl fwhich are confinedin slots in the plate-holder by means of straps 3. Through the outer ends of arms 3 are tapped thumbscrews 3 which bear against the surface of the plate holdemjand these arms 3 are engagedaiid normally held down by 3* attached to the exterior' oftheplateholder. Whenthe serewsifl are; loosened springs 3 rock the clamps on their pivots 3 and hold armsfi 'retracted into the notches intheba'r 3"; but-if the" screws 3? are turned inward the clamps can berocked so asto project arms 3' beyond the edge of the bar 3", (see Fig. 3.) ,Before'a plate P is slipped into the plate-holder 3 the screws 3 are loosened,and arms 3are retracted as described; then the plate P can be slipped into the plate-holder, the bar 3 occupying the slot 79 in the plate ;then the screws 3 are turned inward causing arms 3 to engage the plate atone edge of the slot ,2), and tend to turn the plate in the plate-holder, but this rotary movement of the plate is prevented by the engagement of the other edge of the slot 7) with the opposite side of the bar 3', consequently the plate P will be expanded within and against the inner surface of the plate-holder 3, and will be securely clamped in this expanded position; and while the plate is so held the plateholder is rotated, thereby rotating the plate, and during such rotation the boring and trimming operations are effected as hereinafter explained.
The plate-holderB is preferably lined internally with a copper sheet, indicated at 3, the outer edge of such sheet being spun up against the end of the plate-holder; such copper lining reduces the friction and prevents scratching the surface'of the plate P while being slid in or out of orexpanded within, the plate-holder.
The plate trimming de'vz'ces.On the forward end of frame 1 is mounted a Slide 6 which is adapted to be moved transversely of frame 1, between suitable guides 1 attached to the frame. Said slide has an upstanding lug 6 which is perforated for the passage of a tool clamp 6 which holds a cutter and trimming tool 6. I This tool, see Figs. 2, 9 and 1 has a straight cutting chisel point 6 and a beveled cutting and trimming edge 6, in rear of the point. The plate 6 is also provided onits under side with a perforated internally threaded lug 6 which depends through a slot 1 in the top of the frame 1 and "is engaged by a threaded shaft 6, hearings in the frame 1 and is provided on its outer end with a handle 6" By turning this shaft the slide 6 can be moved transversely of frame, and the springs shown in which is supported in suitable cutter moved to and from the plate-holder. The tool 6 is so located relative to the plateholder that when a plate isproperly positioned in the plate-holder and the cutter is advanced, it will first cut the head off of the plate by means of point 6 the plate being rapidly rotated by and with the plateholder; and then by further advancing the tool 6 the beveled cutting edge (3 of the cutter will engage the edge of the plate and trim it down and bevel such edge as is desired to prepare it for engagement with the cylinder-plate clamps. The tool 6 can then be retractedfout of the way by properly manipulating th'eshaft 6 7 The boring dem'ces.-Arranged axially of the plate-holder 3 and pro ecting therethrough is a bar 7, which also extends through the bracket 1 and is thereby supported upon the frame 1, the bar 7 being located at one side of the bearing of the shaft 4. In the under side of bar 7 is a longitudinal groove in which is mounted a slid-able rack 8 which also passes through a slot in the bracket 1. The forward end of rack 8 is fastened to a tool-carrier 8 slidably mounted on the bar 7, and carrying adjustable trimming tools or cutters 8 which are secured thereto by bolts 8. The carrier 8 can be moved longitudinally on bar 7 by shifting the rack 8. To the rear of rack 8 is connected a strap or rope 8 which runs over a pulley 7 hung on the rear end of bar 7and has a weight 8 attached to its free end, said weight being sufiiciently heavy to normally draw the tool carrier 8 back against the bracket 1, thereby withdrav-ring trimmers 8 from operative position within the plate-holder 3.
The tool carrier 8 may be moved inward, when desired by the operator, b means of a pinion 8 meshing with rack )ar 8 and mounted on a transverse shaft 8 having hearings in brackets 1 attached to frame 1; said shaft extending to the shaft 4 and having a worm-gear 8 meshing with a worm 4 on shaft 4. The pinion 8' is loose on the shaft 8, but may be locked thereto, when desired, means of a suitable clutch. As
l igs. 5 and 6 gear 8 has a clutchface 9 on one face adapted to be engaged \by a sliding'clutch-membcr 9 splincd on shaft 8 and havin a groove engaged by a roller 9'" on a hand lever 9, which is pivoted at 9" on bracket '9 attached to bar 7. By properly shifting this lever 9, the clutch 9 can'be thrown into or out of engagement with the clutch 9, and consequently the gear 8' can be caused to rotate with the shaft 8 at will. Preferabl after the plate is trimmed as above escribed and the tool 6 retracted out of the way, the operator throws clutch 9' into engagement with the gear 8, and the latter causes rack 8" to move thetool carrier 8 forward on bar 7- until it lit til
ll. tli. but ,Wd? h il traverses the entire length ofthe late in holder 3. The-cutters-8 on the too carrier having been previouslyyproperly adjusted, operate toborefout or'trim the interior of the plate P, to-the exact diameter desired; and as the plate is. firmly expanded against theinterior of the'plate-holder thei late is truly and accuratelyboredso as-tot truly and snugly upon the--plate-cylinder of the press. When the carrier8 hastraversed through the plate the clutch 9"is thrown out of engagement with the'gear'8', and
thereupon the weight 8 draws the tool car.- rierbach to the initial position out of the way. Then the shaft 5 can be stopped-and the finished plate removed.
An indicator or'pointer 12- may be attached to one'ot-the bearings-Qadjacentthe cutting, devices to indicateto the operator the particular length of; the finished plate and assist him in properlyxpositioning the plate-in the plate holder.
