I

As herein exemplified,the invention is embodied 1n a mach ne where n the stereotype plate is slid or placed freely within the cylinder with its straightedgesresting on horizontallyv disposed ftracks or guidei ways, the cylinder thereuponbeing calledinto rotation byifhan'ds operated means.

the 'cylinder begins to rotate, the mechanism looks or clamps theg plate firmly within the "cylinder and .so holds the plate 'as it passes near the center of FigLl- (and looking at.

the trimming and shaving'fdevices, The trimmingand shavlng. are completed on a "single revolution ofthe cylinder, and as the cyl nder comes to 'rest on the Icompletion'of such revolution, the; stereotype plate isu-nlocked or unclamped;preferablyby alltOf maticallyoperating devices, preparatory, to its removal from the machine, -either hand or by mechanical means. -It1will be understood, however, that in certain of its" features or aspects the invention isapplica- ,ble 'to other forms of machines than the "embodiment. V

one briefly described above and hereinafter described in detail as the present preferred 4 Referring now indetail to the exemplifiestion of the accompanyingdrawings, the irvention is shown applied to and constituting a partof a stereotype plate trimming niachine, in which machine the cast plate is re from the casting machine ceived with the tail or riser attaclied'thereto,

plate sliding upon its straight edges-upon tracks or guides located longitudinally and i very nearly centrally within the cylinder. its the plate runs or slides in upon the guides, it fits loosely within thec cylinder, the convex or printing surface on the ex- ".erior of the plate being thus, and thereby out of contact with the inner surface or the cylindrical body of the machine. 1 r

the machine, passing out in the sainejdirection but at the opposite end from i which'it. came in. The plate is usually conveyed out Preparatory to starting the machine on th trimming operation, the stereotype plate a" is raised from the guides and is clamped i firmly and closely against the inner surface of the cylinder; After the plate so clamped, the cylinder makes a rotation, and during such rotation the two ends of the plate are carried past rotating saws, located atj-either end of the cylindrical body of the inachin'e,and the head of the plate is there-. by'trimmed and the tail thereof is severed from the plate, and that end of the plate also properly trimmed. Atfthe same time, the concave back of the plate is carried past one or more fiXed shaving knives, which shave the surface of' the concave ribs on the back of the plate in a wall known manner.

The plate is then'unclamped, and'as so finished or perfected drops to and rests on its straight-edges upon the tracks or guideways within tliemachine body. It is then slid along the tracks or guideways out of of the trimming'machine proper, as justdescribed, by automatically operating lllGCllanisin, but such mechanism is not shown or described in thepresent case, as any form'. of withdrawing means may be employed so far as the present invention is concerned.

p The present invention as applied to such a machine, relates primarily to novel means operating automatically to clamp the stereotype plate, as already. described, prepai'a tory to trimmingor fiI11Sl1111g,tlI1Cl secondari- 1y to means cooperating therewith for effecting other functions, such as automatic means forunlocking the'plate after it has been trimmed or finished and means for 'eflectin b and controlling the rotation of the cylinder, 7 together with the other niechanisms herein ferred'to. r a I 7 Referring now to thedetails of construction of the embodiment illustrated in the ac 'companying drawings, a plate carryingcyl- 1nder 1 is arranged preferably horizontally,

and is supported in a pair of annularfranies or bearings 'Qa'ndfi, within which frames the cylinder is rotatable. I The annularbeain frames 2 and 3 ai'e'mounted upon a suite h t. l L

able machine base 4, inc traekways or centrally and longitudinally of the interior wall "or the cylinder l, very nearly asemi' circumference apart, so that as the plate 00 is slid into the machine, its straight edges will rest u on and slide alon the 'uides o ly positioned in front of the machine to aid in this operation;

The embodied form of means for trinimingthe head and'cutting oifthe tail of the plate w comprises rotarysaws 10 and 11, T

at the opposite ends of the cylindrical body 1 of the machine.- The saws 10 and 11 are guides Sand? ai'eai'ranged within and near ator, a suit-abletable or support beingusuat 9 in our ,copend fixed upon a shaft 12 mounted in bearings 13 and i l carried upon the machine base The sawslO and 11 iiiay beprotected by casings 10 and 11 respectivelysecured to the bearings 1st and 13.: The shaft 12 is driven in anysuitable manner, as by gear 15 driven byfiany suitabledevices, not shown I The shaving of the'concave inner ribs of the stereotype plates s effected by one or more shaving knives or blades 16, indicated conventionally in the drawing; 7

A machine of the general type so far described is shown and described in Patent No; 1,126,741 to Wm. Evensen dated Feb.

2, 1915. In t e present the stereotype plate holdii'ig'and clamping means, is designed and constructed to 013 preferred embodiment of crate inconjunctionwith the machine start!v r 'ing and machine stopping devicesor mechanisms, that is the devices for starting and stopp ng the rotation of the cylinder 1 to effect the finishing of the plate and thereafter to leave. it in position to be withdrawn or discharged upon the completion of the llnlslllllg operation. In the embodied and exemplified form V of 7 means for rotating the cyl nder 1, a gear a 11mm I 7 ring 26 encircles the cylinder 1, and has 'tion f the cylinder 1 from the gear as will be later described.

, The gear ring is loose onthe cylinder and i p is driven by suitablemeansnot shown The unclamp the plate afterthe completion of plate clampingidevice comprises a cam 615' gear ring 26 is comiectable to and discon- 'n'ectable from the cylinder 1,to eifectthej rotation of the cylindertogether-with effecting certain otherfunctions, as will hereinafter appear.

Referring now to the embodied form of plate clampingmeans, mechanism is pro,-

vi-ded adapted to engage with-one of the straight edges of the plate, to lift it'ofl' [the guide 6 or 7 andto press the 'platefirmly and solidly, and yet Without toofmucl1 -pres-' sure, against the interior ofthe cylinder 1.

In theembodied form, this means is p osir' tively acting, but this is non essentialsofar asconce' rns nany features of the present n: I

vention.

ated clamping blocks 4:5 are. provided mounted on the cylinderll and located breaks or interruptions in the guideway or track 6 or7,;jand are slidable to and fro to. clamp and to uncla'mp the plate. The

clamping block asshown has its upper surface even with or .just below-the top of the track 7 while'the plate is being fed in, and is pressedupwardly by mechanism set. in motion by the operator instarting the machine. In its upward movement it lifts the, plate, fromtrack 7 (as shown in Fig. 2) and presses the plate against the interiorof cylinder 1, preparatory to the'finishingoperationj. Block 45 is moved downwardly automatically by the machine to. free or the finishing operation, permitting its f straight edgeto rest upon the track orgiiide 'way7, preparatory to the feeding outlor discharge of the finished plate.

As embod'ed', the clamping block is fixed to "afslid-e 46, and fixed to. the slide 46 is afblock 47,,with which block the actuating means for the clamping device cooperates. Suitable supporting and guiding meansfor I the members 45,4;5- an'cl t'i arerprovided, and
