This invention appertains to improvements in log writing or graphing machines. The machine is designed to graph colored or symbolized logs on a straight graph at predetermined intervals so as to illustrate graphically various materials, strata and the like,'as may come within the adaptation of the machine.
The primary object of this invention is to provide a machine that will record both color and character symbols in such manner that statistics may be comparatively graphed on a linear record.
Another object of the invention is to provide a machine that will locate mechanically a point on a record strip placed upon a drum and imprint thereon a character or color symbol or a combination of the two for a determined distance.
Another object of this invention is to provide a machine that has numeral keys that coordinate with a rotatable drum so as to bring the desired point into register with an imprinting mechamsm.
Yet another object of this invention is to provide a mechanism that will imprint a variety of colors upon a log record strip.
Still another object of this invention is to provide a spacing and resetting mechanism so as to permit each successive color or symbol to be joined on the record to the preceding color or symbol without a break.
A still further object of this invention is to provide a grilled shield that may be printed therethrough for the purpose of indicating certain desired effects.
Another object of this invention is to provide independent inking means for each printing face.
A further object of this invention is to provide a shield that may be reset to cover the exact amount of color imprinted so as to prevent overlapping with the succeeding imprint.
While, for the purpose of simplicity and clarity in describing the mechanism and function of this machine, a specific useis described, it is to be understood that the machine is adaptable to many industrial andcommercial fields and it is not to be construed that the use of the invention is to be limited to any particular field. For the purpose aforesaid, the machine is described for use in graphing geological strata and formations, it may be used with equal efiicacy ingraphing logs of imports and exports of various commodities, population, data for various races and countries, for graphing production of agricultural commodities for comparison as to locality and kinds. The above suggestions make it apparent that 65 the use of the machine is applicable to practically every kind of graphic comparison utilizing statistics.
With the foregoing objects in view together with others that will become apparent as the description proceeds, reference is to be had to the drawings which illustrate a preferred embodiment of the invention, but it is to be understood that in adapting same to meet specific needs and requirements, the design may be varied and changes in the minor details of construction resorted to within the scope of the invention as claimed without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof reference is to be had to the following description and to the drawings in which like reference characters designate like parts in the several views.
The numeral 2| designates the frame or housing of the machine which encloses an accumulator mechanism and an imprinting mechanism. The housing 2| preferably is mounted on resilient feet 12. The housing 2| is divided into accumulator and printing compartments by a wall 2|a.
The accumulator mechanism has tiers 2) with index keys 22 slidably mounted therein, to accumulate and index spaces by unit divisions, each tier having the keys thereon numbered from one to nine respectively. The machine as shown emperspective view of the 35 bodies four tiers of index keys which gives the maximum of 9,999 units of indexing capacity, however, by slight alteration or addition of similar mechanism, the machine can be made to any desired capacity. The index keys 22 are normally pressed upward by springs 22a thereon and are provided with stops 23 that vary in normal spacing from tier 2|b, according to the respective keys, along each tier, as shown in Fig. 3, that is, a stop for a key carrying the numeral one allows the key to be depressed sufficiently to permit coacting pawls 25 and 25a to engage one notch in accumulator racks 24; likewise keys carrying the numeral nine. for instance, may be depressed nine times as far as keys carrying the numeral one, so that the racks 24 will permit the pawls to engage the ninth notches in the racks 24.
The index keys 22 engage and bear against the upper sides of accumulative actuating plates 26 which are pivoted on rods 28 extending transversely in the housing 2|, which permits an arouate movement of the plates 26 and pawls 25a carried thereby upon depression of a key. Each accumulative actuating plate 26 has a rack 24 pivotally suspended from an end thereof, and it also has a pawl 25a fixed near the pivot rod 28 in position to engage the rack of the next superposed plate 26. The pawl 25 is adjustably fixed to wall 2 la of the housing for accurate adjustment to less than one unit, as shown in Fig. 5. Each accumulative actuating plate 26 extends the width of each bank of keys and has a coacting spring 21 that is attached at one end to the accumulative actuating plate 26 and at the other end to the accumulative rack 24 to keep the rack in engagement with the respective pawl 25 or 25a. Adjustable stops 69 are provided above the accumulative actuating plates 26 to limit the upward movement thereof.
Upon depressing index keys 22 on the various tiers of keys, the various accumulative actuating plates 26 are depressed. The uppermost index key 22 will move only the uppermost plate 26, but the lowermost key or any intermediate key will move all of the plates above it, through the racks and pawls. Coacting accumulative racks 24 move with the plates and engage pawls 25 and 25a to hold the accumulative plates to which said racks are attached, against upward movement until the racks are released by the pawls. A ratio of 1 to 9 exists between the accumulative racks and accumulative actuating plates in the form of the invention as shown; however, other ratios may be used when desired to meet specific needs. In the case of graphing oilfield logs, the last accumulative rack and the coacting accumulative actuating plate would bear the same ratio as to the tier of keys having the highest numerical order. That is, if a log to be graphed was for a well not to exceed 4,999 feet instead of for a well not to exceed 9.999 feet, the upper rack 24 would carry five notches instead of ten, and the ratio of the accumulative actuating plate pivot to the pawl would be a ratio of 1 to 4 instead of l to 9.
Upon depressing an index key on the lower tier of keys it will act proportionately, through the rack and pawl connections to the other accumulative actuating plates to pull all accumulative actuating plates down a proportionate amount. The top accumulative actuating plate is moved downward in proportion to the depression of the various index keys thereof.
The uppermost plate 26 carries an arm 29 having a rack segment 36 formed thereon for transmitting the motion from the keys and plates. Rack segment 36 meshes with a gear segment 3| which is fixed by a set screw 10 to a shaft 32, extending transversely in one side of the housing 2|. A gear segment 33 of the desired ratio is also attached to the shaft 32 and meshes with a pinion 34 which is secured to a shaft 35 extending transversely in the other side of the housing 2|.
A totalizing drum 36 is secured on the shaft 35 and is rotated by the shafts 32 and 35, and the gearing 30-3| and 33-34, an amount corresponding with the depression of the respective index keys. The set screw 10 permits adjustment of the gearing to coordinate the drum with the index keys 22. A suitably divided calibrated log or record strip 31 is detachably secured to the drum 36 as by hooks 58 at one end and by a clip 38 at the other (Fig. 2). A cover ll hinged to this part of th housing permits access to the interior thereof for removal or replacement of a record strip on the drum 36. A torsion spring 55 has one end attached to a side of the drum 36 and the other end attached to a side wall of the housing 2| in a relation to return the drum to its initial position upon release of the racks 24 by the pawls.
A spacer-reset bar 39 (Figs. 1 and 5) is used to set the machine in zero position by the complete depression thereof. The bar 39 is spring supported on prongs 39a slidable in the housing 2|, and the lower end of one of these prongs 39a has a pin and slot connection with a lever 46 (Fig. 5). A slidable linkage 40 is attached to the lever 46 and forms a lost-motion connection between spacer-reset bar 39 andan accumulator rackrelease-plate 4| which is slidably mounted upon screws 42 on the wall 2|a of the housing 2|. Accumulator rack-release-elements 43 are attached to plate 4| in positions to engage the lower ends of racks 24 upon forward movement of the plate 4|, to cause the disengagement of the racks 24 from pawls 25 and 25a. A spring 44 acts on the plate 4| normally to hold the accumulator release elements out of engagement with accumulative racks 24.
A rod 45 is connected also with the lever 46, and extends therefrom to a lever 48 which is attached to a shaft 49 (see Fig. '7), on which shaft 49, cam 50 is secured.
A spacer shield 5|, has a hub 52 movably mounted upon the shaft 35 (Fig. 1), and is held in frictional engagement with a corresponding hub 53 of the drum 36 by a compression spring 54 sleeved upon the shaft 35. Upon normal turning of the drum 36, as by means of the index mechanism above described, the shield 5| will remain in constant relation to the drum due to the frictional engagement between the hubs 52 and 53. After a printing operation, which is always at the same point with respect to the drum, the initial depression of spacer'reset bar 39, causes the cam 50 to move spacer shield 5| into the position indicated by dotted lines at 5|a in Fig. 7, in which position this spacer shield 5| exactly covers the previously printed color on the record strip 31 until the drum 36 is advanced the length of the printing face, but the shield 5| moves one step with the drum, until depressed again by the cam 50. This movement of the cam 50 takes effect through the initial movement of bar 39; further movement of the spacer-reset bar 39 will cause loose linkage 40 (Fig. 5) to engage the lug 41 on the accumulator rack-release-mechanism 4| to release the racks 24 and permitting the spring 55 to turn the drum back to zero position, ready for the succeeding indexing by keys 22.
The drum 36 has a normal tendency, under torsional tension of the spring 55 to return to a zero position if not restrained by the engagement of the accumulative racks 23 with the pawls 25, 25a. Therefore, a constant tension is held by the spring on the accumulator index mechanism and by the slightest movement of any of the index keys 22 the movement is transmitted, without loss of motion, to the drum 36 which rotates a corresponding amount. The drum 36 rotates the number of spaces that correspond with the number on the depressed keys, thus placing the drum in position for imprinting of a character or color symbol from a selected printing face 56 (Figs. 7, 11) on the calibrated record strip 37. There are a plurality of printing faces 56, one or rrore for each symbol or color to be printed. The printing faces 56 may be of any suitable material, such as rubber or metal. as the nature of the work demands. These printing faces are amxed to type bars 51 pivoted in the housing it, so that upon contact with the drum 36 the selected printing face will be in .vertical alignment with the record strip 37 that is attached to the drum 36. The type bars 57 are actuated by keys 59 which are connected therewith by connecting links 60. Springs 6i normally hold the keys 59 upwardly tending to cause type'bars 57 to remain in horizontal positions. An individual inking pad 62 is provided for each printing face 58 and is mounted upon a pivoted angular member 83 that has a coacting spring 64 bearing ,against the angular member 83 in such position/as to tend to hold the inking pad either firmly on the printing face in a horizontal position or in a vertical position away from the printing face. which movement is accomplished by the shifting of the spring M from one side to the other of the pivoted center by the swinging movement of the an ular member 63. Set screws 641a adjust the tension of the springs $6. The normal upward swinging movement of a type bar 51 causes the inking pad 62 to move to the position shown in Figure 9 and upon return of type bar 57, a trigger finger 65 trips the inking device to the position shown in Figure '7. In this manner each printing face is individually inked with the desired color upon each stroke of the respective key 59.
In certain types of graphing, such as graphing broken formations on geological graphs, it is desirable to impr nt symbols or colors through a grill or screen to obtain specific efiects. This may be accomplished by depressing a bar 68 (Figs. 1 and 7) that is connected through a rod 6? with a grilled shield 58 pivotally mounted in the housing 2! beside the drum 36. This movement will cause the grilled shield to swing into position between the drum and the respective printing face. The grilling on this shield is made of very fine wire or other suitable material such as will not impair printing on the record strip and yet will present a grilled appearance thereto.
In graphing logs of geological formation, as is encountered in drilling oil wells, after the drum 3B is rotated to the desired positionby the index mechanism above described, any of the various keys 59, representing various formations, are depressed. Two keys of each formation may be provided if desired and any key upon the upper tier may be struck at the same time as any key on the lower tier, each key being designed to cover only one-half of the strip and thus give a dual formation symbol side by side, or each key may represent a different formation and may print successively a single width of formation symbols upon a strip.
Various adjustments are provided to keep the various mechanisms coordinated with exacting accuracy.
