This invention relates to a hand operable printing or multigraphing machine, and has for its object an improved organization of parts whereby any manuscript, design, or printed message may be rapidly produced in multiple and at a minimum of expense, being thus particularly useful for the rapid and cheap production of notices of meetings to be sent out to members of an organization, reports, or notices which are to be distributed among the members of a factory group, or even cheaply fabricable hand bills. The preferred organization of parts here disclosed occupies but relatively small space when not in use, and can be produced very cheaply, and its parts are of such simplicity as not to be easily thrown into a state of disrepair.
In the drawings:
Figure 1 is a perspective of my improved machine, with the message impressing member shown in raised position over the base.
Figure 2 is a large scale cross-sectional View taken along the line 22 of Figure 1 and looking in the direction of the arrows there shown.
Figure 3 is a similar enlarged sectional view thereof, centrally and fragmentarily taken along the line 3-3 of Figure 1 and looking in the direction of the arrows there shown.
Figure 4 is a side elevational view showing in full lines the lowered position of the imprinting member and in dotted lines its raised and rocked position.
Figure 5 is an end elevational view of that end of the base plate and its associated parts Whereon the frame for the support of the printing member is positioned.
Figure 6 is a large scale sectional elevational view of the imprinting member disassociated from the other parts.
A indicates a base plate, preferably provided with foot pieces A, and whose lateral edges are upturned and overbent, as at A to form a guiding runway wherein the sheet-supporting plate B is positioned; if desired, special roller or ball bearings may be employed, as illustrated in Figure 3, to facilitate the easy lengthwise movement of the sheet supporting plate B relatively to the base plate A, though ordinarily lubrication of the engaging edges of the sheet-supporting plate and of the overbent edges of the base plate would be sufiicient. On the under face of the base plate A and lengthwise thereof is positioned a curvedly bent protective strip C wherein is located a helical spring C, which is anchored at one end to the base plate and the other end of which is attached to the remote end of the sheet-supporting plate 3, thus yieldingly holding the same in the relative position to the base plate shown in full lines in Figures 1 and 4. The spring-drawn travel of the sheet-supporting plate B relatively to the base plate toward that end of the machine,
shown at the lower left in Figure 1, and at the left end of Figure 4, is limited by the presence of the base strap E of the supporting frame, which will be hereinafter referred to further.
On the top of the sheet-supporting plate B a 5 pile of paper sheets, as B, is adapted to be rested, and these are held in stacked alignment by the bordering guard pieces B The unguarded end and side of the stack of sheets makes their successive removal after printing very convenient. 10 The exact positioning of the bordering guard B on the sheet-supporting plate B may be adjusted by loosening and subsequent tightening of the milled nuts B which pass through a cutaway frame or extension piece B which is connected 15 with the bordering side guards B already referred to.
Rising from each end of the base of the frame piece E is a supporting upright E, in which is journaled a shaft F whereon is mounted the spring G. One end of this latter is anchored in the adjacent frame upright, and the other in the mass or body of the shaft, so that the shaft F and its supported arm pieces H are held in the raised position shown in Figures 1 and 4, the latter in dotted lines. Connecting the freely swinging ends of these arms H is a shaft J, on which is rockably mounted the curved or segmental piece K, and the rocking of this part K may be effected manually through the medium of the handle or grip L; but the degree of rocking thereof is preferably limited by the stops M and M on two of the corners of the triangular plate M, whose third corner is traversed by the shaft J.
This impression segment K has drawn over its curved sheet metal surface a porous cloth, as 0, such as organdy or the like, over which is drawn a carbon stencil or platen N on which the message display or advertisement desired has previously been prepared either by writing or printing. This platen is held in tightly drawn position over the curved surface of the member K by any suitable or appropriate means, as for example the cleats P and Q, into which the cardboard-reinforced ends N and N of the platen are slipped, and one of which, as for example, N is provided with a small crank throw N for effecting the sufficiently tight drawing of the platen over the curved surface.
In operation the swinging frame H with its supported impression member is lowered over the topmost one of the pile of sheets until its outermost end, as for example, that carrying the cranked platen clip N is located, is in contact with the surface of the topmost paper sheet relatively remote from the supporting frame and strut member E. It is then rocked manually, so that first its right hand end, then its intermediate portion and latterly its left hand portion (as shown in Figures 1 and l) are successively brought into imprinting contact with the paper. Since the position of the impression member relatively to the base plate is held unchangeable because of the shaft J, the described rocking movement of the impression member K results in drawing the entire pile of paper sheets, and with it the sheet-supporting plate B, away from the frame end E of the base plate against the pull of the spring C. As soon, however, as the impression has been completed, the lifting of the impression member and its supporting arms H enables the draw of the spring C to restore the sheet-supporting plate to its initial position, after which the then imprinted top sheet is removed, and the apparatus is ready for a repetition of the described movements of the parts against the next adjacent sheet in the pile. If, however, before the impression member has been lifted from contact with the first printed sheet, it is discovered that there has been a faulty or insufficient impression upon the sheet, the impression member K may be re-rocked over the sheet to produce a stronger impression, with the assurance that whatever impression is then made will be in registry with a comparatively slight one which may have been made previously, because the last acting end of the printing surface is still in contact with the paper sheet, and will consequently maintain the registry of the impressions intact.
Whenever a new or substitute message or display is desired, it is only necessary to remove the platen or stencil sheet N from its position on the impression member and over the porous cloth pad 0, and to substitute therefor a new impression sheet with the variant message or display which may have been selected.
What I claim is:
l. A printing machine, comprising, in combination with a base plate, a pivotally supported frame positioned at one end thereof and adapted to be lowered thereover, a sheet-supporting plate slidably positioned above the top surface of said base plate, means for yieldably opposing the lengthwise movement of said sheet-supporting plate relatively to said base plate, and a curvedly surfaced impression member rockably supported from the overengaging free end of said frame, adapted, when the latter is lowered over the base plate and the sheet-supporting plate, to be rockingly impressed against the exposed topmost sheet, thereby effecting the lengthwise movement of the sheet-supporting plate relatively to the base plate against the draw of the yielding opposing means connected therewith.
2. In a printing machine, in combination with a base plate and a sheet-supporting plate limitedly movable thereover, a swinging frame supported from one end portion of the base plate in position to be lowered thereover and over said sheet-supporting plate, a curvedly-surfaced impression member supported from the free end of said frame in position to be rockingly impressed against a sheet positioned upon said sheet-supporting plate, thereby effecting the travel of both lengthwise of said frame and spring means for yieldingly opposing the induced travel of said sheet-supporting plate lengthwise of the base plate due to the action of said impression member upon its supported sheet and for returning said sheet-supporting plate to its initial position at the end of each sheet-impressing movement of said impression member.
3. A printing machine, having in combination a base plate, a sheet-supporting plate capable of limited relative movement with respect thereto, a rockable frame member supported at one end from a position adjacent one end of said base plate, adapted to be lowered thereover and over said sheet-supporting plate, and an impression member having a curved surface, pivotally supported from the free end of said frame member in position to be rocked in frictional engagement with a sheet positioned on said sheet-supporting plate, thereby effecting a sliding movement thereof relatively to said base plate, and spring means for automatically effecting the return movement of said sheet-supporting plate to its initial position at the end of each sheet-impressing movement.
4. In combination with a base plate, and a sheet-supporting plate slidably positioned thereon, spring means for effecting the return of said sheet-supporting plate to its normal position relatively to said base plate after the operative travel thereof, a swinging frame member supported from an end portion of the base plate in position to be lowered over said sheet-supporting plate,
and an impression member having a curved surface, rockably carried on the free end of said frame member in position to be brought into engagement with a sheet on said sheet-supporting member, thereby displacing the same from its normal position against the draw of its connected spring coincidentally with the transferring of an impression from its curved operative surface upon the sheet.
5. In .a printing machine, in combination with a base. plate and a sheet-supporting plate positioned thereover and capable of limited movement in its own plane relatively thereto, means for automatically returning said last-mentioned plate to its normal position with respect to said base plate, a swinging frame positioned at one end of said base plate, and an impression member. carried by said swinging frame. adapted to be loweredby the downward movement thereof into impressing contact with a sheet positioned on said sheet-supporting plate for rocking engagement therewith, thereby temporarily moving the same against the draw of its automatic returning means.
6. In a printing machine, the combination, with a base plate, of a sheet-supporting plate limitedly slidable above the top surface thereof, means for yieldingly opposing the induced movement of said sheet-supporting plate in one direction and for automatically returning it to its initial position relatively to said base plate at the termination of each cycle of operative activity, a, frame member swingably supported near one end of said base plate in position to be lowered thereover and over said sheet-supporting plate, and a curvedly surfaced impression member supported by said frame member and adapted to be rocked over the exposed surface of a sheet positioned on said sheet-supporting plate, thereby effecting the lengthwise movement of both of the latter lengthwise of the frame member and against the action of the yielding opposing means contemporaneously with the imprinting action of its curved surface upon the inserted sheet.
