HENRY a. Bean, on CHICAGO, ILLINOIS, .assieiq a. so none nrnc rnorrrn corvrrnnx tens OF CHICAGO, ILLINQIS, A CORPQRATION 6F ELLINOISL WORKHOLDEB FOB CUTTING OB DRESSING MACHINES."
Application area ri -n1 i,
T 0 all whom it may concern.
Be it known that I, A. Heinz, a citizen ofthe United States, residing at Chicago, in the county of Cook and-State of 'lllinois, have invented certain new and useful lmproveinentsin lvorkholders'for Cutting or Dressing Machines, of which the following 1s a specification.
This invention relates to improvements in necessary to dress or plane down the back,
This is a very particular operation and must be done with accuracy so that the plate will set or fit correctly. 1 he dressing down has heretofore. been don first on what is known as a roughing machine which planes off the back but leaves the surface rough, after which the plate is olace'd in a planing or smoothing machine for the finishing op eration. f
These machines emhody a reciprocating knife or cutter and co-operating with the cutter, in proximity thereto, one or more steel or iron rollers have been employed, and which rollers are of a'length to extend enirely across the plate and rest upon the back thereof and roll with respect to the back during the cutting of the plate. Pressure is exerted upon the rollers'so as to force or hold the plate firmly against the bed of the machine.
Inasmuch as t iese rollers are of metal, the bodies thereof do not yield, with the result that in the event that the plate is provided with a high portion, the roller will be tilted or raised by such high portion which causes the roller to move out of engagement with other portions of the plate, and as the cutting proceeds. the plate will not be held firmly, with the result that the plate will slip or move causing considerable damage or injury to the plate and often times under these conditions the plate will be trimmed or planed to an uneven thickness, which is not desirable.
With this construction or'type of machine it heretofore been impossible to operate 1-922. Serial No. 548,574.
' upon, two plates at the same time which are of, uneven thicknesses, as; the thicker. plate will hold the roller or rollers elevated above the thinner plate and the latter will not be held atall by the rollers.
Toovercome these diificulties and objections and to provide an improvedroller attachment for machines of this. character, the
body portion or work engaging surface of which roller is adapted to yield to compensate the irregularities of the surface of the plate to be operated upon, whereby the roller will under all conditions exert its pressure upon the back of the plate throughout the entire len th or width of. the plate, is one. of the objects of the present invention.
ll. further object is to provide an improved roller of this character by means of the use of-which two or more plates of unequal tliicknessesmay be simultaneously dressed r planed and each of the plates will be firmly gripped or forced against the bed of the machine by the roller or rollers.
To theattainn'ient of these end sand the accomplishment of other new and useful objects as will appear, the invention consists in the features ofnovelty in substantially the construction, combination and arrange ment of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention and in which- Figure l is a perspective view of a portion of a shaving or dressing machine having a roller constructed in accordance with the principles of this invention applied thereto. a
l igure 2is a detail vertical sectional View taken online 22, Figure 1. V
igure 3 .is an enlarged detail view in vertical section showing the roller in position.
While this improved roller attachment will be described and claimed in connection with the dressing or smoothing of the back of electrotypes, it is to be understood that the same can be used with equal efliciency in the preparing of other forms of printing plates and therefore it is to be understood that this invention is not to be considered as being limited in its use withelectro types.
