UNITED STATES PATENT OFFICE.
GUSTAV W. EHRHARDT AND MERRIAN SCHIAVON, OF CHICAGO, ILLINOIS.
HEATED PRESS-PLATE FOR EMBOSSING.
Application filed January 15, 1914.
To all whom it may concern Be it known that we, GUSTAV W. Enn- HARDT and Mnnnun SCI-IIAVON, citizens of the United States, and residents of the city of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in Heated Press-Plates for Embossing; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon,which form a part of this specification.
In most embossing processes it is necessary to use a heated die member in order to permit deformation of the paper or other material employed without the same being torn. The machines for the purpose have been exceedingly large and cumbersome, requiring a great deal of space and usually only adapted for embossing work.
This invention relates to a heated press plate to receive an embossing die thereon, permitting the same to be used upon an ordinary printing press.
It is an object of this invention to provide an electrically heated press plate adapted to receive an embossing die clamped thereon to receive heat from the plate, thus permitting embossed work to be performed by an ordinary printing press.
It is also an object of this invention to provide an electrically heated press plate having a number of compartments thereon, each containing a heating coil, and with a fireproof lining on the interior of each compartment to protect the same in event of accident to the coil, and further to insure a more even distribution of the heat to the upper supporting plate on which the die memher is clamped.
It is furthermore an object of this invention to provide in combination with a selfcontained heating press plate for embossing dies, clamping members mounted thereon to clamp a die in any desired position.
It is finally an object of this invention to construct a simple device requiring little space and capable of withstanding great crushing stress and of being used with an ordinary printing press, to support and heat an embossing die.
The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.
On the drawings: Figure 1 is a central Specification of Letters Patent.
Patented Feb. 23, 1915.
Serial No. 812,201.
vertical section taken transversely through a conventional type of printing press. Fig. 2 is a top plan view of a printing frame with a device embodying the principles of our invention locked therein and supporting a die member. Fig. 3 is a top plan view of the heating press plate with the top plate removed. Fig. 4 is a section on line Jr-l of Fig. 3. Fig. 5 is a section on line 55 of Fig. 3.
As shown in the drawings: The printing press, which may be of any usual type, is denoted as a whole by the reference numeral 1. A printing frame 2, in which the forms are ordinarily locked up, has mounted therein a heating press plate, the top plate of which is denoted by the reference numeral 3, and quoins 4, and blocks 5, serve to hold the heating member securely in place. Adjustable clamping members 6, are provided near the edges of each of the four sides upon the upper plate 3, of the heating member, with the inner beveled edges of the clamps engaging the beveled edges of an embossing die 7, to hold the same properly spaced and in close contact with the top plate 3, of the heating member.
The heating plate or member comprises longitudinal side members 8, and transverse end members 9, all of which are rigidly secured to one another, and laid loosely and extending transversely between said side members 8, are heavy partition bars 10, which, with the top plate 3, and bottom plate 11, serve to aiiord a series of compartments within said heating plate member. The purpose of the heavy partition bars 10, is to permit the large compressive stresses to which the device is subjected to be transmitted without danger of deforming the top or bottom plates of the device. The compartments are lined with a fire-proofing material 12, such as asbestos, and laid within said compartments are electrical heating coils for the top plate 3. Said coils comprise an insulating member such as pipe clay or other heat resisting material 13, which extends immovably from end to end within said compartment, and has wound therearound, coils of wire 14:. Each of said partition members 10, at one of its ends, is cut away and is provided with an insulating bushing 15, so that the wire on each of the respective heating coils may be passed therethrough to connect the coils in series with one another, as clearly shown in Fig. 3.'
One end of the wire, denoted by the reference numeral 16, is connected into aremovable plug 17 and the other end of the wire, denoted by the reference numeral 18, is grounded upon the end member 9, of the heating plate frame. Another removable plug 19, engages in said printing frame with the contact of the lead wire therein grounded also upon said frame, so that when the respective lead wires from said plugs 17 and 19, are connected to a source of electrical energy, the current will enter through the Wire 16, and flow through the coils, and thence grounded upon the heating plate frame, return to the plug 19.
The upper plate 3, is preferably a plate of high heat conductivity, so that the heat from the various coils may be easily transmitted to the embossing die member 7, lying closely thereon. Also the bottom plate 11, is preferably a poor conductor of heat, so as to prevent loss of energy through radiation. lhe asbestos or other fire-proof lining 12, within the respective heating coil compartments, serves to distribute the heat more evenly, and especially to the plate 3, so that the em bossing die member is thus evenly heated.
We are aware that various details of construction may be varied through a wide range without departing from the principles of this invention. Vi e therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
We claim as our invention:
1. A press plate support for an embossing die embracing a frame, top and bottom plates thereon, heavy removable partitions at their ends interfitting in recesses in said bers, top and bottom plates secured to said side and end members of said frame, and each contacting said heavy partition members, and a plurality of heating coils laid in said frame between said top and bottom plates intermediate said partition members.
3. In adevice of the class described a frame, removable partitions therein, top and bottom cover plates detachably connected thereto affording compartments within the device, a plurality of connected heating coils laid one within each of said compartments, one terminal thereof grounded to the frame, and the other end connected to' a plug, and slotted clamping bars adjustably mounted upon said top cover plate adapted to hold an embossing die in place thereon.
In testimony whereof we have hereunto subscribed our names in the presence of two subscribing witnesses.
