Application September '10, 1934, Serial No. 743,378

12 Claims.

This invention relates to a reproducing apparatus and has special reference to a construction of the pantographic type for reproducing patterns of a template on a desired surface in an enlarged or reduced state or in some translated form thereof.

More particularly this invention relates to reproducing apparatus comprising a base slidable over a surface having a pattern-carrying template mounted thereon and a pantograph including a fixed bearing on the base and linkage mechanism supported thereby and extending therefrom, the linkage mechanism carrying a tracing point for moving over the pattern-carrying template and another tracing point controlled by the first mentioned tracing point for making a copy of the pattern on the surface over which the base slides.

The present invention contemplates the pro- Vision of a reproducing apparatus in which all of the elements necessary for completing the reproduction of the pattern are contained in a single unit or are mounted in a unitary manner on a single base. The base is slidabl'e over a surface and is preferably hel-d in a given plane by a straight edge against which an edge of the base may rest, the pantographic mechanism mounted on the base marking a copy of the pattern on the surface from a template likewise mounted on the base. It is usual, insofar as applicant is aware, to provide templates which are separate and apart from the pantographic mechanism and which, besides being relatively cumersome and awkward to manipulate, are more costly than that construction contemplated by the present invention.

The present construction is compact in form and simple to operate and is capable of reproducing any pattern in an extended or condensed condition or inclined in either direction with but simple adjustments of the pantographic mechanism.

One of the objects of the present invention is to provide a reproducing apparatus of the character indicated above which is simple in operation and construction, is comparatively inexpensive to manufacture and is durable.

Another object of this invention is to provide a'reproducing apparatus of the type above noted vin'which all of the elements entering into the construction for the complete reproduction of a desired pattern form a unitary device.

A further object of this invention is to provide a reproducing apparatus as hereinbefore pointed out whereby the reproduction may be extended or condensed or may be inclined or reproduced in some translated form.

Other objects and advantages will hereinafter be more particularly pointed out, and for a more complete understanding of the characteristic features of this invention reference may now be had to the following description when read together with the `accompanying drawings, in which latter- Figure l is a plan View of an apparatus'embodying the features of this invention;

Fig. 2 is a view similar to Fig. 1 with the template and a tracing point thereof removed;

Fig. 3 is a side elevational view of Fig. 2;

Fig. 4 is a central, vertical sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a diagrammatic view similar to Fig. 2 showing an initial position of the elements in full lines and a changed position thereof in dotted lines;

Fig. 6 isa view similar to Fig. 5 with the elements thereof changed to extend the reproduction and to incline the same in a different direction from that shown in Fig. 5, the elements being shown in an initial position in full lines and in a changed position in dotted lines; and

Fig. 7 is a view illustrative of the character of some of the reproductions possible from the apparatus embodying the features of this invention.

Referring now more particularly to the drawings, the device of this invention is shown as being embodied in a base I0 preferably formed of sheet metal of channel cross section when viewed from one end thereof, the legs Illa and I0b of the channel member providing bearing surfaces on which the plate rides in its movement over the surface upon which the pattern is to be reproduced. The base is indicated as being made of sheet metal, although of course it is to be understood that any substantially rigid material may be so employed consistent with the purposes for which it is intended.

The base is provided with a template Il, for carrying the pattern which, in the present instance, is shown as the letters of the alphabet together with the necessary numerals disposed in contiguous zones. The characters of the template are preferably cut into the face thereof, and the grooves thus formed are of sufiicient width to permit a stylus or other like instrument to slidably engage therewith. It is, of course, to be understood that various patterns may be cut into the pattern-carrying template Il and that this invention is not to be connedfto its use in reproducing the characters specifically shown. 'I'he template II is held in a fixed relation to the face and is spaced therefrom, the plate being held in such spaced relation by the vertically extending posts I2. It is desirable to have the template I I removable so that it may be replaced by a template carrying a different pattern.

A tracing point I3 is slidably mounted over the face of the template, the tracing point carrying a plurality of apertures I4 for registration with the grooves of the pattern to be reproduced. In the present instance there is one aperture for each of the numerals or letters to be reproduced, each of the apertures having suicient movement to be capable of outlining its respective character or zone. The tracing point is preferably formed of sheet metal and is cut out in such a manner as to disclose therethrough the characters of pattern for reproduction, although, of course, it is to be understood that the same function may be performed by various types of tracing points which in some cases may need be no more than a single pin.

An arm I5 is mounted on the base for slidable movement sidewise thereof, the arm having an enlarged head portion I6 and a reduced shank portion I'I. Opposite sides of the enlarged head portion are preferably guided in a sidewise direction by guide rollers I8, which in the present instance are rotatably mounted on the upright posts I2, the guide rollers preferably having circumferential grooves in which the sides of the enlarged head portion ride in a spaced relation from the base.

The enlarged head portion I6 is provided with a shouldered recess I9 for receiving a circular disc 20, the circular disc having a finger-piece 2| extending from a circumferential portion radially of the disc for purposes of manual adjustment. The disc 20 is preferably removably held in position on the shoulder of the recess I9 by a cover plate 22 which is secured to the top of the slidable arm I5 by screws or other similar means, the securing plate 22 being preferably of spring material to permit a rotatable movement of the disc 20 against the tension of the spring plate 22.

The circular disc 20 is provided with an elongated slot 23 extending through the disc radially thereof. The position of the radially extending slot 23 concerns the inclination of the reproduction and will be explained in greater detail hereinafter. In order to predetermine the inclination of the reproduction it is preferable to employ a graduation about the periphery of the shouldered recess so that the disc 20 may be set prior to the completion of the reproduction. 'Ihe slot 23 in the present instance is shown as being straight although the location and character of slot may be changed in accordance with the character of translation desired. An arcuate, tortuous or other slot may give a novel appearance to the reproduction of any pattern so that the present disc 2D may be replaced by another disc having a preferred form of slot.

The shank end I I of the movable arm I5 is pivotally connected to an arm 24, the latter arm being pivotally connected at one end thereof to a post 25 xedly mounted on the base III. The arm 24 is one of a pair of cooperating arms extending in a substantially forwardly and rearwardly direction, the other arm of which is indicated by the numeral 26. One end of the arm 26 is pivotally connected to the base by a rivet 2'I or other securing means in a fixed position on the base, and the inner free ends of the arms 24 and 26 are slidably connected by means of a connector 28 having movement along the arm 24 to any fixed adjusted position thereon by the thumb nut 29. The connector 28 is provided with a roller 30 pivoted to an ear extending therefrom, which roller engages a track formed by the arm 26 of channel cross section. Movement of the connector 28 in either direction will lengthen or shorten the pivotal movement of the cooperating arms 24 and 26 to determine the amount of sidewise movement of the arm I5, as will hereinafter be more fully pointed out.

The free end of the arm 26 is pivotally connected to the end of an arm 3| which extends sidewise of the base, the other end of the arm 3| being pivotally connected to an arm 32 extending substantially parallel with the arm 26 and being preferably of the same length. The arm 32 is pivoted at its other end to the base I0 by a rivet 33 or other securing means. The arm 3I is provided preferably with an integrally formed arm portion 34 extending in a forwardly and rearwardly direction upon the end of which is pivoted an arm 35 extending in a direction across the Width of the apparatus. An arm 36 cooperating with arm 35 is pivoted on the arm 3I and extends in the same direction and preferably parallel with the arm 35, the pivotal points for the arms lying in the same plane and having threaded pins 37 at the opposite free ends for pivotal connection with the tracing point I3. The plate forming the tracing point I3 is provided with extensions on each side thereof for receiving the pins 3?, and the plate is suitably held in position by the threaded caps 38. The arms 35 and 36 are tied together for equal and simultaneous movement by means of an arm 39 extending to be pivotally connected adjacent the outer free ends thereof, the arms therefore being capable of universal movement in a single plane since they are pivotally mounted to move forwardly and rearwardly on an arm which is slidable in a sidewise direction.

A pair of horizontally extending cooperating arms 40 and 4I are disposed on the base, one end of the arm 4I being pivotally connected to the post 25, which latter is fixed to the base, and the other free end being pivotally connected to an arm 42 extending in a forwardly and rearwardly direction. The arm 40, in turn, is pivotally connected at its outer end to the base II] by means of the rivet 43, or an equivalent securing means, an inner portion of the arm 40 together with an inner portion of the arm 4I being slidably and adjustably connected together through a connector 44. The other end of arm 46 is pivotally connected to one end o-f a link 39a, the other end of link 35a being adjustably connected to arm 39 at a predetermined position thereof. 'Ihe connector 44 is preferably slidable on the arm 4I and may be fixed in any predetermined position thereon by means of the nut 45, the connector 44 having an ear extending therefrom upon which a roller 46 is `disposed for engaging a track or guideway formed by the channel cross section of the arm 46. An adjustment of the connector 44 will operate to determine the size of the reproduction as to the height thereof, a movement in one direction condensing or reducing the height of the reproduction and a movement in the other direction extending or enlarging the reproduction.

One end of the arm 42 is pivotally connected to the free end of the arm 4I, as hereinabove stated, the other end of the arm 42 carrying a reproducing point 41 for making the copy of the pattern on the surface. This tracing point may be of any ydesired character, either a colored lead or a container for ink or other marking fluid. Intermediate the ends of the arm 42 is positioned a pin 48 for engaging the slot 23 and extending therethrough to project beyond the bottom thereof.

The pin 48 depends from the arm through the slot 23 for engagement with the upper surface of a presser bar 49, the latter bar being fixed at oneV end andvbeing preferably formed of spring material normally bowed to extend in a spacedapart relation from the base at an intermediate portion engaged by the pin 48. However, in operating the reproducing apparatus to permit the reproducing point 4i toengage the surface, the presser bar is moved downwardly in a direction towardithe base preferably by the finger striking the presser bar at the end designated by the numeral 50, the pin 48 normally being held upwardly with the reproducing point 4i out of engagement with the surface before pressure is applied to the presser bar.

In the operation of the reproducing apparatus, the character or pattern to be reproduced is selected and the stylus or other operating instrument is inserted into the aperture corresponding to such character, the stylus passing through the aperture into the groove defining the Vcharacter and being guided thereby. The movement of the tracing point operates the cooperating arms 4Q and 4| during a movement thereof in a forward and rearward direction and operates the cooperating arms 24 and 2S during movement thereof in a sidewise direction. The arm 42 carrying the second tracing point is, in turn, operated by the forwardly, rearwardly and sidewise movements just recited to guide the movement of the tracing point over the surface receiving the reproduction.

The reproduction may be either extended or condensed or may be inclined as desired by reason of the adjustments hereinbefore noted. For example, a movement of the connector 23 in one direction may reduce the width of the character to be reproduced to an extent such that it may be substantially smaller than the character of the template, or if the ccnnectorjZS be moved in an opposite direction the reproduction may be greater in width substantially than the character of the template. Likewise should the connector 44 be moved in one direction the reproduction Vmay be considerably less in height than that of the original character of the template, or if the template be moved in the opposite direction the height of the character may be considerably greater than the character of the template. The range of reproduction may be substantially from a point to any desired heightand width consistent with convenience in use. Also by means of rotating the disc 20, the diametrically disposed slot 23 may translate the movement of the pantographic mechanism so that the characters or reproduction as a whole are inclined or otherwise formed with respect to the original of the template. The forms of reproduction are illustrated in Fig. 7, and the adjustment as to the height and width of the reproduction is illustrated in the diagrammatic showings in Figs. 5 and 6.

While but a single embodiment of this invention is herein shown and ydescribed it is to be understood that vario-us forms thereof may be apparent to those skilled in the art without departing-'from the spirit and scope of this invention, and therefore the claims hereof are to belimited solely by the prior art and the scope of the appended claims.
