M. M. LEFTWICH 5 METHOD OF SETTING RULES FOR PRINTING Filed April 7, 1950 INVENTOR ATTORNEY atented Apr. 19, 1932 MORRIS M. LE'ETWICH,
PATENT OFFICE OF TULSA, OKLAHOMA METHOD or snrrme RULES FOR PRINTING Application filed A ril 7,
This invention relates to printing plates for printing designs made of thinlines, and more specifically to printing straight lines either horizontal or vertical of the sheet, or
both.
The objects of this invention are to produce a printing plate for printing a line or a plurality thereof on a sheet whereof the usual form is that of a plurality of lines spatially related in both horizontal and vertical directions of the sheet, such as sheets for bills, financial statements, ledgers, and the like; which plates may be made of materials not now used for this purpose; which may ['5 be quickly made with the spaces between the lines of any predetermined value; which plates are made without the use of molds; in which the body of the plates is entirely nonmetallic, the only metal used being the 2 printing edges, which plates, therefore, re-
quire only thin metal strips for forming the line-printing elements; which avoid the necessity of melting metal parts or of applying temperatures in manufacture differing from normal room temperatures; which plates may be made more rapidly and with less manufacturing equipment than is now possible for production of plates which make similar imprints on sheets, and the production' of which plates is far less costly than that of any other type or character of plates for making similar imprints now known to applicant.
Other objects will appear as this description proceeds.
Briefly, this invention includes the use of thin strips, preferably of metal, one edge whereof has the exact thickness required for the thickness of the lines to be printed,- and the width of the strip being substantially equal to the thickness of the plate. These strips are set edgewise on a planar surface, being spaced as desired, and the plate is made by pouring in, around and between the strips some substance which is initially plastic and which later hardens or sets, thereby anchoring the strips in the desired position with their printing edges all in one plane and having the desired thickness. Vherever the printing strips cross each other, they are slot- 1930. Serial No. 442,233.
ted as is usual from opposite edges toward the middle of the strip width, which character of construction is well-known.
The plastic self-hardening substance which anchors the strips and with them makes the complete plate, must, of course, be thinner from the back to the front than the width of the strip, so that no portion of this hardened material may touch the paper and make an imprint thereon. Different methods may be used to limit the thickness of the hard material, as later set forth herein.
With the foregoing and other objects in view, the invention consists in the novel and useful formation, construction, interrelation and combination of parts, members and features, as well as mode and methods of use thereof, and steps and performances taken and had, all as hereinafter described, shown in the drawings, and finally pointed out in claims.
In the drawings 2- Fig. 1 shows an isometric perspective view of two line-printing strips notched for assembly in directions transverse to each other for making a printing plate having both horizontal and transverse lines.
Fig. 2 is a plan view showing the rear surfaces of a plurality of horizontal and vertical strips interlocked together and placed on a flat assembly support or plate.
' Fig. 3 is a fragmentary vertical cross-sectional view taken along line III-III of Fig; 2 and drawn'to an enlarged scale.
Fig. 4 shows a typical form illustrative of the character of the imprint made from the line-printing plates.
In Fig. 1 10 and 20 each designate a single strip having thin beveled printing edges 11 and 21 respectively and rear or butt edges 12 and 22 respectively. Slots or notches 13 are made in strip 10 from the printing edge toward the middle, while in strip 20 notches 23 are made from the butt edge toward the middle, as indicated. 95 Obviously, the notches in strip 10'interlock with those in strip 20, there being a strip similar to strip 10 for each of the notches 23 in strip 20 and there being a stri similar to 20 for each of the notches 13 strips lie against the assembly surface 15,
a plastic material may be poured in between the strips and around them and in an amount sufficient to nearly reach the top of the thin printing edges of the strips, but insufficient to project as high above the assembly surface 15 as the thickness of the strips, or the strips may be laid together with their printing edges downward against the assembly surface 15 and a thin layer of some easily removable and cheap material may be poured or placed be tween and around the strips against the surface 15 as indicated at 14 in Fig. 3. On top of this layer 14 of material first placed or poured on to surface 15, the plastic substance 16 which subsequently hardens is poured filling up the interstices between the several strips. When this second material l6 hardens, the entire unit is lifted from assembly surface 15 and the removable layer 14: is shaken or pulled out leaving the printing edges of the strips 10 and 20 piglecting beneath the surface of the plate There are, of course, many fillers to fulfil the purpose of 1a which is simply to prevent the hardened substance constituting the plate from reaching a thickness equal to the width of the strips or bars, such as sand, chalk, powdered charcoal, sawdust, or any finely divided substance which may be simply shaken out, or wax, parafline and the like which may be pulled out from the openings formed by the intersecting bars, or the limiting layer 14 may be entirely omitted, the hardening substance poured in, and the upper surface thereof merely spooned or scooped ofiwhile it is still soft. The substance of which the plate is made and indicated by the numeral 16 in Fig. 3, is preferabl an earthen substance which is cheap, lig t in weight, easily mixed, and preferably rapidly hardening and also has the characteristic of taking'a set or becoming hard at printingroom temperatures. Preferably it does not shrink when it hardens, but holds tightly to thestrips and anchors them in position. -As examples of such substances are artificial stone compositions, which are chiefly of cement or plaster of Paris, or'a mixture of the two, or other similar earthen self-hardening material. Obviously such materials are far less costly than metals, require no heat application at any time, either when mixing, placing or hardening, and weigh much less than metals, so that there is a considerable money saving in using such materials, as well as that of the cost of making molds for pouring metals, and the cost of melting and pouring as well as that required for equipment for melting and pouring metals, and when a number of such plates is stored away, the invest- .ment and the weight to be supported on shelves or in any other manner are both much 7 less than for'metal plates. Having described my invention in connection with illustrative embodiments, forms and arrangements of parts, it will be understood that many variants thereof are possible to those skilled in the art, and my invention, in its broader aspects, is not limited to the particular construction or application herein shown and described, as changes in size, proportions, configurations, arrangements, assemblage, interaction, juxtaposition and mechanical relations, as well as additions, omissions, substitutions, combinations and alter-a tions of forms, parts, members, features, and in the kind and order of operations and successive steps, may be made without departlast mentioned rules from their back edges 9 at the desired points; said depths of the notches in the two sets of rules totaling approximately the depth of the rules; placing the last mentioned rules in spaced parallel relationship with their printing edges upon a horizontal fiat surface; separating the other set of rules in spaced parallel relationship and at right angles to the first mentioned set of rules; the printing edges of the last mentioned rules being faced downwardlywhereby interlocking of the rules will occur; sprinkling a granular substance down into the interstices of the grid work of the rules; inserting hardening means aboveth granular substance; allowing the same to harden; and then lifting the grid of rules from its sup porting surface.
