Description
March 7,1936. H. w. LAME SHOW CARD MACHINE 3 SheetsSheet 2 INVENTOR. %aC
Filed June 7, 1934 Patented Mai. 17, 1936 9 Claims.
This invention relates to printing mechamsm, and has for its object an improved organization of parts adapted especially for the printing of display or advertising cards from rubber or rubber faced type.
In contrast with the ordinary printing operations, wherein metal type is used and where humdreds or perhaps thousands of copies of comparatively closely printed text are to be struck off, the printing of show or advertising cards, preferably from rubber or rubber-faced type, presents problems far removed from the ordinary printing operations just mentioned. Not only are comparatively few cards of any particular design or wording needed, as for example, for the display of particularly advertised bargains in various sections of a department store, but in addition, for the sake of attracting customers attention, often fantastic designs both in letters and figures are needed, and when they have served their purpose for the particular display desired, are in many cases of no further use.
Ihe preparation of such type in metal is so far more expensive than similar outlinings in rubber that considerations cf expense, because of the temporary and limited use of the cards involved, dictate the use of rubber or rubber-faced type.
If such character of type were to be used in a direct impression press, that is, where the plane 30 of the type-supporting bed as well as of the printing surface of the type approaches and recedes from the sheet to be printed in a substantially perpendicular direction, or at least where the impact of the type against the sheet is simultaneous throughout the set-up design or wording, the distortion of the ruboer faces of the type form and chosen design would be of negligible consequence, if indeed it occurred at all. However, tonsiderations cf cheapness of apparatus and rapidity of production, and of quick substitution of one design for another, point to the traveling roller pressure method as the most feasible for effecting the imprinting of the design upon the sheet or card.
Here again difficulties are encountered as regarde the use of rubber-faced type as contrasted with other type, in that the travel of the compression roller, whether hand-operated or in case the roller be a correlated part of the mechanism in that as the roller precedes from one end of the sheet to the other, whether directly resting thereupon or upon an interposed blanket, the net applied pressure as transmitted to the sheet and type surfaces is in a. direction generally acutely angled to the planes thereof, and consequently there is a tendency for the relatively yielding rubber type surface to spread or be distorted from its truc position in the direction in which the roller is traveling instead of truly perpendicularly. This is true whether the letters or figures appearing in the design be circular, as for example an 0 or whether they be straight-lined, as for example an N; in either case those sectiens of the letters in which there are'intermediate vertical portionsassuming the roller to be traveling from one side of a sheet to the ctherare pushed out of alignment, so that in addition to the intended design of the letter or figure, there is an undesired cloud or shading present at the side of the letter contours in question. Furthermore, it often happens when rubber type is being used that despite the utmost care, the first impression upon the paper due to the applied pressure thereon is not sufficiently uniform tocompletely transfer the design to the paper or card, and a second impression is nocessary. Provision must therefore be made for permitting the inspection of a card thus supposedly thoroughly printed upon before its removal from its registering position with respect to the type, which has already made a partial impression, in case it becomes necessary to indulge in a second pressure operation.
To obviate the objections to such conditions,
While taking full advantage of the opportunities 0 cf economical operation and rapid production and substitution of the designs which it is desired shall appear upon the display cards, I have devised the apriaratus forming the subject matter of this disclosure; its structure and working principles are illustrated in the accompanying drawings, in which Figure 1 is a perspective of one form of my improved construction, showing a card in position With respect to the other operative parts, and With the type arranged in desired relation for the printing of the design desired.
Figure 2 is a lengthwise sectional elevation, showing the relation of the various operative parts to one another, being taken along the line 2-2 of Figure 1 and looking in the direction of the arrows there shown.
Figure 3 is a fragmentary elevational view, partly in section, of a complete apparatus, varying from Figure 1 in that it suggests the possibility of using a hand roller, instead of the correlated roller members shown therein.
Figure 4 is a fragmentary and partly sectioned view similar to Figure 3, but intendedly diagrammatic, in that it is designed to bring outthe normally acting directions of the roller-applied force upon subjacent cover and sheet and type members.
Figure 5 is a plan view of the device shown in Figure 1, the cover being lowered, and some of the parts them subjacent thereto being shown in dotted lines.
Figure 6 makes use of the letters spelling the word NOW to show, in the two representations embodied in this figure, the normal or unclouded impression which is desired, and the blurred or distorted impressions due to the warping of the type under roller-applied pressure.
Figure '7 is ;a detail view taken from Figure 1 and looking in the direction of the arrow thereon, showing the preferred form of spring catch for holding the sheet-supporting clips in holding position on the under face of the cover.
Figure 8 is a fragmentary perspective on an enlarged scale showing a preferred form of demountable hinge or trunnion support for the pivoted lateral edge of the sheet-supporting cover.
Figure 9 is a detail elevational view, largely in section, taken along the line 99 of Figure 8 and looking in the direction of the arrows there shown.
A represents a supporting base or frame, and B the bed plate of my improved printing mechanism. Along either side of the bed plate are positioned spring rails C urged upwardly at their center portions by the leaf springs D, along which the ends of the top roller E are designed to travel. In the form shown in Figure 1 the top roller E is rotatably supported in a frame N, which spans the breadth of the frame A and extends sufficiently therebeneath for the lower rollers F to engage against the corresponding under surface of the frame, so that, subject to the adjustment of the top roller by means of the eccentrically operating catch G which works upon the ratchet face H of the frame, the desired degree of compression can be exerted upon the bed plate B and its supported type, sheet or card and cover members hereinafter to be discussed, as the roller-supporting frame is moved lengthwise of the frame B by manual draw upon the handle I.
The top surface of the bed plate is preferably provided with a waxy or sticky surfacing B and if desired, with an arrangement of intersecting guide lines B for facilitating the positioning of the type. A pure or unvulcanized rubber surface may also be employed for this purpose. This surface is of such stickiness or adherent character that once the type is placed thereon it is reliably held in position but removable by intentional manually applied pressure. on its top surface are arranged the several type blocks J; generally some of them are large, as for example the display of a price for an article named in comparatively small letters; these are positioned on the bed plate to form in reverse the design desired to be imprinted, but in any event they are of such size as compared with the supporting blocks J that the rubber or similarly flexible printing surfaces J are very appreciably spaced from one another, so that, as brought out in Figure 2 there are alternated elevations due to the depressions where there is no inking surface present, which make the yielding of the edges of the rubber letters under roller pressure almost inevitable as regards any presently known apparatus for counteracting this tendency.
Along one lateral edge of the bed plate is hingedly supported a cover member K, which is provided with clips L for temporarily holding a sheet or card M in position on the under surface of the cover when the latter is lowered over and into contact with the type surfaces. Bearing in mind the unreliability of securing a complete imprint from rubber type, especially if a relatively thick card is to be imprinted, and the resultant necessity of perhaps securing two impressions from the same type set-up, which of course must register, it Will be obvious that this cover efficiently serves this purpose, in that when raised up to inspection position of its supported sheet and then again lowered against the type surfaces, the already printed or partly printed design on the card will be returned to true registry with the arranged type design.
Since, however, if the sheet or card be a thin one, and if the remarked-upon spaces between the surfaces of the type elements be quite large, even a sheet or card is often inadequate t0 prevent a laterally fiexing pressure upon the rubber type units as the roller passes over the sheet, or even over an ordinary printing blanket positioned over the sheet. This tendency is brought out in Figure 4, wherein the arrow X represents the horizontal direction of travel of the roller over the bed plate and its supporting parts, the arrow Y represents the type-distorting acuteangular pressure as received from the roller, While the arrow Z represents the truly perpendicular direction of received pressure which would not result in any lateral distortion of the type. If the material of which the cover is made be too thin or toc yielding, the resultant effect of the rollers traveling pressure thereover is undulatory, and this, not being absorbed by the sheet or card or even by a flexible blanket, is accordingly transmitted, even through the card or sheet, to the soft-surfaced type, whose margins on the far side of each letter from that initially feeling the rollers pressing influence are more than likely to be bulged or distorted, in the manner illustrated by the second one of the illustrative representations of NOW shown in Figure 6, which contrast very unfavorably with the regular and cleaneut Ietterings in the left-hand one of the representations of this word. The further the actual inked surfaces of the several type elements are 5 spacecl from one another, the worse this condition is likely to be, since for example the wide spaces desired between the quite large letterings on a sale or display card often leave valleys or spaces between them of such size that the roller would often tend to sink very appreciably beneath the plane of its normal and intended pressure level. And when its continued travel would bring it to the edge of the next type letter or figure encountered, the deforming impact upon the normal contours thereof as the roller rides over its near edge to resume its ordinary pressure level would additionally distort the rubber or other soft material of which its printing surface is formed.
It is also wcrthy of remark that this elimination of any transmitted acute-angular pressure contributes as Well to the maintenance of the type units in their desired and arranged position on the waxy top surface B of the bed plate. The use of this latter is advisable, in place of any locked-up form of type set-up, because of the small number of impressions of display cards of any particular design would render a resort to the latter prohibitivcly expensive, both in time and as to the apparatus needed.
I, therefore, exercise considerable care in the determination of the character of the cover, which may be of some stiffened fabric or wall board material, either of which is suficiently rigid, as compared with the pressure from the top roller, to translate any acuteangularly directed force into a truly perpendicular force before it reaches the distortable type surfaces, as well as to resist any tendency to an undulatory flexing of the cover. In either case only the truly perpendicular pressure components are transmitted tothe sheet and type surfaces, the acutely angular forces being absorbed within the body or mass of the cover. In this manner and by such means I have. found it possible to accurately and economically print display cards from the relatively cheap rubber type without the probability of encountering a distorted impression upon the card when supposedly finished.
I desire it to be understood that the specific method of assuring the swinging action of the cover member, so that its supported card Will reliably register With the type design, is comparatively immaterial; either a truehinge connection With the bed plate frame, or a pivotal or a .trunnion connection may be resorted to, without departure from the intended scope of this disclosure. Some such connection between the cover and the bed plate seems preferable and conducive to quick operation of the device.
The preferred form of operative connection between the sheet-supporting cover and the base plate is illustrated in a rather enlarged scale in Figures 8 and 9. Rising from the edge of the base plate near either end of the cover K are trough-like members or cradles P, in the base or central web of each of which is positioned a rather light helical spring Q, upon which the ends of the lateral bar R of the frame of the cover K rest, being accordingly pressed lightly upward. These bar ends R may be lifted from the cradles and inserted therein quite easily when the cover K is in uplifted or vertical position or nearly so; but long before the lowering of the cover over the type has been completed, the shoulders S on the covers frame, adjacent the bar ends R have engaged under the projections T on the cradles so that the bar ends R. are then held clown, against the upward thrust of their springs Q, and cannot be lifted out of the cradles until the cover member has again been raised. Thus an accurately locating hinge or pivoting construction is afforded for guiding the swing of the cover, no matter how many times it may be raised or 10W- ered. But if removability of the cover be a matter of minor importance, any suitable form of hinge or pivot connection between the cover and the bed plate may be resorted t0.
And in Figure 7 there is illustrated a desirable but by no means essential form of catch mechanism for locking the bar V, on or near the swinging edge of the cover K, in position over the outer or free ends of the sheet-holding clips L. The bar V which is slidably traversed by the cotter pin W in each of the cages W being yieldingly held in the depressed position shown by the action of the helical spring W When it is desired to release the ends cf the sheet-holding clips L, slight finger pressure upon the bai V in the direction of the extreme edge of the cover K suffices to overcome the pressure of the springs W so that the bar V as a whole is moved clear of engagement over the ends cf the clips L.
