LYHAN. A. WHEAT, OF BATTLE CREEK, MICHIGAN srmomr. on nmc'rno'rrrn .crnmnna son rnmrmeennssiis.
Application filed April 8, 1909. Serial No. 487,674.
To all whom it may concern:
Be it known that I, LYM N A. WHEAT, a citizen of the United States, residing at the cit of Battle Creek, Calhoun county, State of ichigan, have invented certain new and useful'lm rovements in Stereoty or Electrotype ylinders for Printingesses, of
which the following is a specification.
This invention relates toimprovements in stereotype or electrotype cylindrical plates forrmting presses.
TEE objects of this invention are: First,
to provide a stereotype or electrotype cylindricglfiplate or printlng cylinder which can be r.
ily' adjusted in a press. Secend, to provide a cylindrical printing plate which can be readily "manufactured with out the necessity of ,t-rimmingfor boring.
Third, to provide means supporting an electrotype' or stereotype cylindrical printing plate in a rotary press. Fourth to provi e an improved construction wherein the metal of a stereotype or electrot pe cylindrical printingplate is reinforce to better withstand the strain of hspeed.
Further objects, and o jects relating to details of construction will .appear from the detailed description to follow.
I accomplish the objects of my inventionby the devices and means descr bed in the following specification,
The invention is clearly defined and point ed out in the claims.
. panying drawing, forming a part of this.
. A structure embod ing the features of my invention is clearlyi ustrated'in the accomlines taken on a. ine corresponding to line porting means showin 11 of Fig. 3, the dovetail being omitted. Fig. 2 is a=detail lo itudinal sectional view showing details 0 construction of the method of su porting the cylindrical printing plates. llg. 3 is a transverse sectional view on line 3-3 of "Fig. 2.. Fig. 4 is a detail view similar to Fig. 1 the dovetail detail omitted) of a modified arm of the supwhich may be require in certain instances to add to the stability of the structure.
lates and its supporting a continuous shaft In the drawing, similar numerals of reference refer to similar pal ts throughout the several views.
Considering'the-numb ared parts of the drawing, thesides of the ress 1, 2 are of the usual form and the stereo .ype or electrotype printing plate 3 is in cylindrical form being a continuous cylinder as appears from reference to Fig. 3. The ends are shaped either in casting or by bo] in afterward and receive the dividedmand re 4, 5 which are provided with shoulders 4' ,5. This mandrel is driven by the gear 6- tnd the outer end of the shaft issupported l @y a brack'et- 7 containing a suitab e bearii lg. A bushing 9 surrounds the shaft 8 01 the mandrel and permits of its adjustment back and forth,
which is accompllshed by the hand wheel 13, which controls the so] cw 10. which is in the bracket 11. 'A" lock-1 nut l2'is' provided for retaining the same securel 1n place. The arts ofthe mandre. 4 an 5 are provide with shoulders 4' a 1d 5', respectively, to engage the ends of the printing cylinder.
The metal is preferab cast on a steel shell.wh-ich is cut" with ovetail.. ways as clearly appears in Figs. 5 .andB, such -dove- -Eail-14 Sand 15 clearly app :aring in these two res, the said steel shel. bei a reinforce. T e dovetail cuts are :traig t across .on chords of the circle forn ing the inner surface in the forni of an o atagon.
Type metal is not adh :sive and doesnot unite with other metals u uless there is some special preparation as a f ux, and in this device where it isdesired tr cast the printing surface, it is not fiuxing means as it would cause the metal to adhere to the matrix an 11 would spoil the print' surface. The type metal must be retaine in place by wha- I choose tocall a clench or clenching means, the same as plaster adheres to metal or wooden lath on the wall of a dwelling. This is what I mean by the expression clenching in the claims. 1
Where it is desired to' provide extra suport for the cylinder, tl [S is accomplished y a shaftlfi, which fits into a hole in the.
ssible ;0 make use of any produced by a stereotype or by an electro-- type process or. in any equivalent way from type metal.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a printing press, the combination of a printing cylinder, in the form of a continuous metal shell; a divided mandrel, the sections thereof being formed for insertion into the opposite ends of said printing cylinder with shoulders to engage the said opposite ends; independent supports for the separate sections of the said mandrel; and means for clamping the mandrel sections into en agement with the opposite ends of said cyllndrical shell, coacting substantially as described and for the purpose specified.
2. In a printing machine, the combination of a divided mandrel, the parts of which are supported on suitable journal bearings;
means for driving the same; a shaft extending between the sections of said mandrel screw-threaded at its inner end to couple the same together; a shoulder on the said shaft for clamping the parts into engagement with the rinting cylinder, and a second shoulder or use in driving the mandrel-sections apart; and a printing cylinder to be engaged and carried between the parts of'said mandrel, coacting for the purpose specified.
3. In a printing machine, the combination of a' divided mandrel, the parts of which .are supgorted on suitable journal bearings;
means or driving the same a' shaft extend ing between the sections of said mandrel screw-threaded at its inner end to couple the same together; a shoulder on the said shaft for clamping the parts into engagement with the printing cylinder; and a printing cylinder to be engaged and carried between t e parts of said mandrel, coacting for the purpose specified.
4. In a printing machine, a printing cylinder conslsting of a shellof strong reinforce metal, having straight transverse dovetail grooves therein on chords of the surface of said cylinder, with aprinting face of type metal cast upon the same in a continuous cylinder and clenched into the dovetails of said reinforce metal.
In witness whereof, I havehereunto set my hand and 'seal in the presence of two wltnesses. 4
