PRESS-PLATE.
Specification of Letters Patent.
Patented Feb. 23, 1915.
Application filed June 24, 1913. Serial N0. 775,580.
T0 all whom t may concern:
Be it known that we, GUs'rAv W. EHR- HARDTl and MERRIAN SCHIAvoN, citizens of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improveprovements invpress plates adapted for use in connection with printing presses for embossing, and has for its object to so construct a plate of this type that the same can be easily handled.
A further object of the invention is to provide a pla-te of this type which is electrically heated, andone which is exceedingly simple in construction, durable and efficient in operation.
With these and othenobjects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which v:-
Figure 1 is a plan view of the device. Fig. 2 is a similar view with top plate removed. Fig. 3 is a sectional view on line 3-3 of Fig. 1. Fig. 4 is an end view of the device.
Referring to the drawing, the numeral l designates a metallic casing which is preferably rectangular in shape and consists of sides 2, ends 3 and top and bottom plates 4 and 5, respectively. Arranged transversely, and spaced apart is a plurality of porcelain tubes 6, said tubes having their ends engaging the sides 2. The sides 2, ends 3 and top and bottom plates 4 and 5 are lined with asbestos sheets 7, which prevent injury to the casing by heat from the coils.
Passing through the sides 2 of the casing 1 are screws 11, which serve to brace the casing.
i By employing the members 6 in tubular form and engaging their ends against the sides 2 so as to seal the same, we provide for dead air spaces therein, which because of their non-conducting quality will cause the heat generated in the coils 8 to radiate outivard and thus contribute to the more-effective operation of the device.
What is claimed is A press plate for printing presses, consisting of a casing comprising sides and ends, and top and bottom plates connected thereto, fa plurality of porcelain tubes arranged transversely of the casing and spaced apart with their ends engaged in and closed by the sides ofthe casing, a non-conducting lining for the casing, heating coils encircling said tubes and connected in series, said coils and tubes filling the space vertically in said casing, and a plug mounted in one end of the casing for receiving the terminals of the coils.
In testimony whereof, we aiiix our signatures in the presence of two witnesses.
GUSTAV W. EHRHARDT. MERRIAN SCHAVON. Witnesses:
JOHN W. KREPPEL, ANGELO DEPEDER.
