To all whom it may concern: s 1

Be it known that I, HENRY A. WISE WOOD,

T a citizen of the United States,residing at New York, in thecounty of New York and State of New York, have invented a new and useful Machine for Finishing and Cooling stereotype Plates, of which the following. is a specification.

This invention relates to machinesfor finishing stereotype printing plates, and par: ticularly to that type thereof 1n wh1ch the plates are fed along substantially in a straight path, and preferably. down an incline into position to be cooled. v,

v Whilethe featuresof this invention are capable of general use, it is herein presented more as an improvement on certain previous inventions on which I have filed the arch and be battered while being raised,

and to provide for allowing the edges to resume normal condition when in the arch; also to provide forproperly ad uSt ng'the distance'the plate israised on both sides;-

to provide for conveniently and eifectively lowering the plate out of the' arch; and generally, to improve and simplify the construction and operation of. stereotype plate shaving machine's.

Further objects and advantages of the in-' shaving out the inside of the plate.

When the .plate first 'rests on the rollers.

vention will appear hereinafter, I

Patented Apr. 191 5 tain parts omitted, showing certain parts in elevation. Fig. 6 is asimila-r'view' showing the left-hand side-with the parts in-another position; and Fig. 7 is a fragmentary view showing how one of the supportin rollers for the edge of the plate is operate ,Although this invention is not limited'to the gravity type of shaving machines, it is particularly adapted thereto, and is'shown' as applied to that type. The machine is illustrated as embodying a frame 10 hav ing an inclined top provided with ahorizontal receiving. table '11 at one end, and hav:- ing an inclined runway formed byrollers 12 arranged onan incline for receiving the edges of the plates from the table 11. L0-

cated between these rollers is a saddle 13 s over which the plates move, and at the end of which are located a set of cams on the longitudinal shaft .14 of the machine. Two

of v these cams numbered 15 and 16 will be described hereinafter. The third cam 17 operates a roller 18 shown in Fig., 4, which is connected with a sliding stop 19, normally pressed by aespring 20 111130 a position to prevent the passage of the plate. As the shaft 14 revolves this stop is drawn down and allows the plate to slide down the incline into the shaving arch 21, where it rests on rollers 22. In this arch is shown a stationarv member or saddle having aflat steel spring26 thereon for engaging the inner side of the plate and checking its down-f ward motion as it approaches the discharge end thereof, so as to prevent its striking a stop 27 at the lower end with too much force. The stop27 is operatedby a track cam .28 on the shaft 145, so as to come into proper position to stopthe plate as it reaches the bottom or discharge end of the shaving arch. It will be understood that a shaving blade 29 is mounted on the shaft l4= for 22 these are at their lowermost position, and

they are caused to carry the plate up into the arch, in proper position to be shavedby the following mechanism: The cam 151previously mentioned, operates a cam roller 30' vertically sliding rack 35 which carries a support 36 on one side of the machine on which one set of rollers 22 are mounted. In a similar way the cam 16 operates a rock shaft 37 on the other side of the machine which carries arms 38 connected by links 40 with a slidable member 410. A fixed member 41 carries adjustable rods 42, which, carry springs 43 that yieldingly force upwardly a support 44 on which are mounted the rolls 22 on the other side. It is to be observed that the limit of the rocking motion of the shafts 33 and 37 is capable of adjustment by means of studs 45 and pairs of set-screws 46 mounted on the two arms extending from the shafts and connected with the forked levers. The operation of the two rock shafts after the set screws are properly adjusted causes the plate resting on the two sets of rollers to be elevated the same distance on both sides, unless the plates differ in length, in which case the variation is taken up by the compression springs 43. Means is provided also whereby as the plate is raised, its lower edges are sprung inwardly so as to clear the sides of the arch to prevent the plate rubbing against the arch. The mechanism shown for accomplishing this result consists of levers 50 pivotally mounted on the supports 36 and 44. These levers are provided with springs 52 at the bottom which normally swing the lower ends inwardly and the upper ends outwardly. They are provided with cam rollers 53. adapted to engage stationary cams 54-56; the sides of the machine. These cams are iprovided with a :giit-out portion 55 at the bottom and ai s co'nd less pronounced cut-out portion 56 further up. Between these cut-out portions the cam has a rise 57. On the upper ends of the levers 50 are located inwardly projecting gripping edges or jaws 58. 'As-these parts are raised, the rollers 53 are forced inwardly by the cam 54 so as tocause ,the edges 58 to grip the edges of the plate outside the matter, and compress them toward each other. As the parts approach their uppermost position, the cam roller 53 drops into the top cut outs 56, thus allowing the edges of the plate to spring back to fit the arch tightly, the plate being held in this position by the rolls 22 during the shaving operation. As the shaft 14 continues its rotation the cams 15 and 16 operate to lower the rolls 22 in an obvious manner and allow the parts to drop by their own weight, assisted by the weight of the plate. An extension spring 60 is'provided connected with arms 61 extending from the two rock shafts, and having an ad justment 62 for the purpose of starting the parts downwardly if they stick or show any tendency to remain up. As the plate drops back the cams 54 cause the levers 50 to press the edges of the plate in so as to escape the sides of the arch and then release them, the plate being supported by the rollers all the time. The cam 28 is so timed that when the plate drops back to its lowermost position, the stop 27 will be withdrawn so that the plate can slide along down over it. As the plate hashad at the most only a preliminary cooling in the hollow arch, to and from which water flows through pipes 620, it is now fully cooled.

In order to prevent the wetting of the printing surface of the plate, and do away with the difiiculty of drying the face of the plates thoroughly, the improperperformance of which operation injures the rollers of the'press, the following mechanism is provided: Surrounding the shaft 14 is a hollow semi-cylindrical cooling saddle 63 connected-with a'source of water supply by means of a series of pipes 64. The outer convex surface of thissaddle is provided with perforations 65 and with a series of rifle grooves 66 running substantially horizontally, over which the water discharged from the inside runs in continuous unbroken streams, without producing a spray. The plate is cooled by said streams in an effective manner and no water is allowed to touch the printing surface. The water discharged from the cooling saddle passes down through the bottom of the machine where it is caught and-discharged through a pipe 67. On the driving shaft 68 is a worm 78 operating a worm wheel 79 on the shaft 14. This worm is located in an oil casing 69. The end of the shaft 14 is shown as provided with an internal gear 7 0 meshing with a gear 71 on a shaft 72 journaled to rotate in the frame and provided with brackets 73 thereon carrying a drying device 74 for the interior of the plate. The supporting rolls continue to the bottom of the frame, and the plate brings up against a stationary stop 7 5 and is removed from the machine by hand or, in the absence of the stop, may be discharged on a table or truck located at theend of the machine. It will be understood of course that various shaving, trimming and other finishing means will ordinarily be employed with this machine. They are not shown herein as they are now well-known in the art and they can be applied easily to this machine in several ways, as for example, as shown in both of my prior applications mentioned above.

I do not herein claim the features of the cooling mechanism, the combination thereof with the finishing mechanism, or the method of cooling because these matters constitute a part of the subject matter of my co-pending divisional application Serial No. 557,107, filed April 23, 1910, entitled Machine for cooling stereotype plates.
