To all whom 'it may concern:

Be it known that l, Lnwrs E. PADDACK, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented cer A further object of the invention is to provide in a planograph means for manipulating an ink well asso# ciated with the pen such manipulation being accomplished by actuating means adjacent the tracing point and convenient to the hand of the operator.

A further object of the invention is to provide improved means for accommodating a metallic strip provided with characters which are to be transferred to the drawing being made.

A further object of the invention is to provide a planograph of general and improved construction.

- A further object of the invention is to provide in a planograph an ink well mounted upon improved operating means adjacent the pen and in position to be swung beneath the pen to charge the pen with ink.

With these and other objects in view, the invention comprises certain other novel constructions, combinations and arrangements of parts, as will be hereinafter more fully described and claimed.

In the drawings :*Figure 1 is a perspective view of the planograph with portions broken away to more clearly illustrate the construction. Fig. 2 is an enlarged, de-

, ried and operated. Fig. 6 is a top plan view of the pen andiink well operating parts. Fig. 7 is a top plany view ofr the machine showing the cover plate and pivoted v arms removed and showing the means for maintain- Liftinzwwmtwawnaewwwwa ing the` matrix in parallelism. Fig. 8 is a detail view of a fragment of the camplate.

Like characters of reference designate corresponding parts throughout the several views.

The planograph forming the subject-matter of this application comprises a base plate 10 having a flange f 11 formed along the back of said plate and with portions 12 extending downwardly for a short distance along the ends. Rigidly secured to the back edge oi the base plate are frame pieces 13 and 14 disposed obliquely to the edge of the said plate and connected at the back to an integral or rigid frame strip 15, in parallelism with the base plate. The base plate 10 and frame strips 13, 14 and 15 form the frame work of' the device upon which is mounted the operating structure and the matrix. UponA the base plate is slidably -mounted the matrix carrier 16 having along one edge an inturned flange 17 and atits opposite end provided with a strip 18 corresponding substantially in thickness with the matrix 19 and forced against the edge of the said matrix by means of springs 20, lateral movement of the said strip being permitted by reason of slots 21 formed transversely in the said strips and engaging upon studs 22 rigid with the matrix carrier so that with the matrix in position with the carrier, as shown in Figs. 1 and 7, the strip 18 bears against one entire longitudinal edge of the matrix and holds the matrix in position `edge of the matrix carrier and by which the matrix carrier is held in parallelism with the base plate and movement in suoli parallelism permitted. Such transverse movement of the matrix carrier in parallelism is accomplished by means of a plate 30 provided with an inclined cam slot 3l engaging a pin 32 carried upon an ear 33 at the edge of the matrix carrier and rigid therewith, the said plate 30 being provided with a knob 34 extending through a slot 35 in the cover member 3G and by a rivet 37 through a similar slot 3S in the opposite end of the said cover member 36, the said slots 35 and 38 extending in alinement with each other and in longitudinal parallelism with the edges of the base plate and the matrix and matrix carrier, and whereby the plate 30 is moved longitudinally relative to the base plate and cover member 36, thereby moving the cam slot 3l in relation to the pin 32 to move ythe pin 32 and the matrix carrier laterally.

Upon the rear frame plate 15 adjacent its juncture with the side frame plate 13 is erected a spindle 39 by means oi an upright 40 rigid with the said frame and upon the said spindle- 39 are pivoted the extremities of arms 41 and 42, the arm 4l extending normally substantially parallel with the strip 15 and the'arm 42 extending normally substantially parallel with the frame piece 13. Upon the extremity of the arm 41 is pivoted an arm 43 which said arm 43 is maintained in movable parallelism with the arm 42 by means of a.

cross bar 44 movable longitudinally of the said arms 42 and 43 by means of sleeves 45 and 46, slidably mounted upon the said arms respectively and retained in'longitudinal adjustment by any approved means, as the thumb screws 47. The arms 42 and 43 are provided with scale marks, as indicated, to facilitate the proper adjustment of the sleeves and 46 upon the said arms, whereby the said arms are moved synchronously upon the movement of either one. The cross bar 44 is pivoted upon the sleeves 45 and 46, as by the studs 48 and 49, carried. by the said sleeves embraced by clips and 51 rigidly secured to the opposite extremities of the said cross bar 44. The arms 41 and 42 are supported against sagging by means of guy wires 50 and 51 connected at one end to swivels, as at 52, mounted upon the upper extremity of the spindle 39 and connected at their lower ends by means of tension screws 53 and 54 with the said arms 41 and 42, respectively, adjacent their extremities. -Upon the cross bar 44 is slidably mounted a sleeve 55 maintained in operative position upon the said bar in any approved manner, as by the thumb screw 56 inserted through the said sleeve and engaging the said bar and the position of the sleeve upon the bar being determined by means of graduations formed upon the said bar, as shown particularly in Fig. 1. Upon the sleeve 55 is rigidly secured a clip 57 through the bowed portion of which is inserted a pen barrel 58 being retained therein in any approved manner as by the thumb screw 59and carrying thepen stock 60, slidable therein. Rigid with the pen barrel 58 is an upright 61 having adjacent its upper end a pulley 62 over which is extended a cord 63 connected with the upperend of the pen stock 60, and by which the said pen stock and its associated pen 64 are raised. The cord 63, after passing over the pulley 62, passes thence under the pulley 65, mounted upon the upright 61 and about a pulley 66 upon the spindle 49. From the pulley 66the cord 63 passes over a pulley 67 carried upon an upright 68, adjacent the extremity of the arm 43 and passes thence downward through an opening 69 formed in the arm 43 and under a pulley 70 beneath the said arm and upwardly again through an opening 71.

4"Upon the extremity of arm 43 is rigidly mounted a sleeve 72 having a central bore 73, in which is slidably mounted a bar 74 provided at its lower end with a tracingpoint 75. The sleeve 72 is closed at its upper end by a plate 76 and the bar 74 is held adjacent the lower extremity of its movement by means of a spring 77 disposed within the opening 73 and bearing upon the upper end of the said bar, the said bar being somewhat cushioned by a weaker spring 78 disposed beneath the head 79 of the said bar and bearing against a shoulder 80, the tension of th e said springs being equalized when the spring 77 is considerably expanded and the spring 78 considerably contracted. About the sleeve 72 is disposed a tube 81 slidable upon the said sleeve by reason of a slot 82 engaging upon a screw 83 rigidly secured in the sleeve 72 and by another slot 84 embracing the angular shank 85, by which the sleeve 72 is secured to the arm 43. The tube 81 is provided at its upper end with an adjusting screw 86 from which a wire or other supporting means, as 87, extends downwardly through the plate'76, and bears upon the top of the spring 77. Y

Rigidly secured to the tube 81 is a collar provided at the rearward side with an adjusting device comprising a spool 89, upon which is wound the cord 63 and tension screws or nuts 90 and 91, by which rotary displacement of the vspool is prevented. At the side opposite the adjustment means a handle 92 .is pivotally secured to the sleeve 88, and by which the tube 8l is moved longitudinally upon the sleeve 72. Upon the sleeve 55 is also mounted a sleeve 93, through which extends a shaft 94 rotatable through a limited are and held yieldingly in position by means of a spring 95 engaging a pintle 96, carried by the said shaft 94, and extending through a slot in the sleeve 93. The shaft 94 carries at its lower end an arm 97, provided at its end with resilient fingers 98 adapted to embrace an ink pot 99 and to hold the same in operative position. The shaft 94 is also provided at its upper end with an arm 100 disposed at an angle relative to the arm 97 and engaged by a cord 101, extending about a pulley 102 carried upon the sleeve 55.' The cord 101, after passing about the pulley 102, extends to and passes about a pulley 103 carried upon the stud 49 and to and connected with a bell crank lever 104, pivoted, as at 105, adjacent the extremity of the arm 43, the other end of said bell crank lever beingv provided with a knob or' other approved finger engaging means106, adjacent the tracing point 75. Upon the lever 104 is mounted a cord adjusting device comprising a spool 107 about which the Acord 101 is wound and tension screws 108 and 109 by which rotary displacement of the said spool is prevented.

The extremity of thearm 43 is carried and supported by means of acaster 110, swiveled adjacent the end thereof, as upon the stud 111 and moving upon the plain surface of the base plate 10. The frame pieces 13 and 14 are provided with longitudinal slots 112 and 113 respectively, within which are mounted slides 114 and 115, respectively, carrying a guide strip 116 preferably transparent and in position to engage and hold a sheet of paper, as 117, upon which the device is being operated. The said strips are also preferably provided with lmobs, as 118 and 119, for lifting the device, the said device being substantially balanced at the point shown by the said knob. Adjacent they end of the base plate 10 is also preferably erected an upright 12,0 carrying an arm 121 provided at its extremity with resilient fingers 122 similar to the ngers 98 and for engaging and holding the sleeve 81 when the machine is hung upon the wall or similarly stored.

In operation a sheet of paper, as shown at 117 is placed and held in position by means of the guide strip 116, and a matrix 19 provided with the desired characters placed in the matrix carrier 16. The matrix, shown in the drawing, is provided with the letters of the alphabet, but it is to be understood that the said matrix may be and is in operation provided with any approved characters, symbols, words, designs, configurations or other desired characters, dependent upon the use to which the device is to be put at the time it is being operated. The matrix carrying the desired -and approved characters or configurations are slidably inserted in the matrix carrier 16 and held against acci-4 dental displacement by means of the strip 18 and springs 20.l The pen 64 is positioned at the point upon 4which it is desired to form the character and the matrix 'slidably moved so that the character to be transferred is in proper position for engagement by the tracing point l, The` handle 92 is then grasped and the tube 81 moved: downwardly by that meansuntil the tension of the spring 7'7 overcomes the tension of the weaker springy 78,whereupon the rod 74 is moved downwardly until the point 75 is engaging within the depressed charactersot` the matrix. The movement of the tube 81 downwardly moves also the spool upon which is carried the cord 63, which releases the tension upon the said cord and permits the pen stock 60 to move downwardly by gravity in the sleeve 58, until the pen 64 is in contact with the sheet. The tracing point 75 is then, while in contact with the character, moved about said character and the character is reproduced by the pen 64 in such proportion as has been predetermined by the position of the cross bar 44, upon thearms 42 and 43. When another character is to be formed the tube 81 is raised by the spring 77 upon the release oi the handle 92 and tension applied thereby to the cord 63 synchronously raises the pen stock 60 and pen 64 out oicontact with the paper 117. The matrix 19 is then moved until another character is brought in juxtaposition with the tracing point 75, whereupon the operation is repeated. Before lowering the pen into contact with the paper the pen is inked by moving the bell crank lever 104, thereby exerting tension upon the cord 101, and rotatably moving the shaft 93 to move the ink pot 99 beneath the pen 64. The pen, is then, by means of the handle 92 lowered into the ink pot 99, and charged, and after being so charged is raised and the ink pot moved by releasing the bell crank lever 104.

The matrix 19 will generally be provided with more than one row of characters and the several rows are brought into position for operation by sliding the plate 30 longitudinally oi the base plate 10 by means oi the knob 34, upon which move the cam slot 31 engaging the pin 32 moves the matrix carrier laterally and therewith the matrix 19 carried thereby.
