CENTERING OR IOSITIONING MECHANISM FOR TYPE CASTING A ND GOMPOSING MAGEINES.

To all whom it may concern:

Be it known that we, JOH-N SELLERS BAN- oRorT and MAURITZ C INDAHL, citizens of the United States, and residents of Philadelphia, in the county of Philadelphia and State of Pennsylvanla, have invented certain new and useful Improvements in Centering or Positioning Mechanism for Type Casting and Composing Machines; and we do hereby declare the followingto bea full, clear, and exact description of thesame, reference being bad to the accompanying drawings, forming ,part of'this specification, and to the figures and letters of reference marked thereon.

This invention relates to the class of-automatic type casting and composing machines.

in which a plurality of spaced .matricesrepresenting different characters are operated;

upon by a centering or positioning mechanism to selectively present individual Inatrices opposite a mold-and in-register therewith. In commercial machines ,of this val-1 riety twosuch centeringmechanisms are.usu-- ally employed for controlling motions in;

relatively transverse directions, and each is equipped with a signal responsive gage whose pitch or measure corresponds with or isproportionalto the spacing-of themati'ices in the direction. of motion controlledthereby,- the arrangement being such that-the diecaseorother performing member is operated on what is sometimes designated :the point-topoint system, owingl-to the fact that the ad-.

justed member is s ifteddirectly from one of a series of stations to any other in said series, withoutihaving to be returned each,

time to a zero or initial position. Accuracy,

speed and capacityare prime factors in the success of such machlnes and inertia the.

stumbling block, and in the compromise effected between these vantagonistlc .elements the weight and dimensions of the die case with its containcd matrices is reduced to a minimum consistent with the requirements of the machine. Hence it is that the commercial machine, being specially designed to deal with the more popular or commonly used type sizes-twelve point and under has its e case proportioned to accommodate a maximum of two hundred and twenty-five matrices arranged in fifteen parallel rows of fifteenmatrices each. Thematrices are uni- Specificatiomof Letters Patent.

formly spaced in each direction 1011a scale of two tenth inch, thus limiting vtheareaavailable for any given character toasquare two tenths inch on-each side. llheseedimensions ,are inadequate for the larger size characters pertaining .to :fonts of fourteen point and over, to accommodate which either the capacity of the die case for numbers must ;be

greatly reduced, or special machines or equipments based upon the new measure must be provided. An example of such acto Work in harmony with both the normal and abnormal-matrices. It so happens,.however, that this unit 1s inexcess, ofthe require mentsof some. ofthe .larger pointsizes, hence unnecessarily diminishes the capacity. ofthe die case and itis ,the;purpose ofthe present invention to overcome in a measure this defeet by increasing the capacity of the machine inlthis respect without in any degree interferin with the action of .the machine in the per ormancev of its normal functionsin dealing Withmatrices of normal or' standard dimensions.

To these ends the invention consists ;in providing the centering mechanism with a supplemental or auxiliary gaging means whose pitch-ormea-sure differs from yetharmonizes with the signal controlled gaging devices so thatthe latter may be employed foridesignating either normal or abnormal matrices and centering them opposite the mold.

The invention also includesminorfeatures of construction and arrangement the particulars whereof are point-ed out in the claims.

In the accompanying drawings illustrating a preferred form of embodiment of said invention,'I*igure 1 -is a top plan view of a type casting and composing machine with the improvements applied thereto, the paper metal injecting and galley mechamsms being omitted for clearness. Fig. 2

is a partial horizontal section of the machine showing the additions and cooperati'ng parts. Fig. 3 is a vertical section through the right hand adjusting mechanism of Fig. 1. Fig. 4 is a similar view, the parts being in a difl'erent position. Fig. 5 is a partial side elevation of the machine with the improvement shown applied thereto. Fig. 6 is a horizontal sectional view of the Valve mechanism on the line ww, Fig. 5. Fig. 7 is a vertical sectional view of one of the valve chambers with the actuating lever in elevation.

Like letters-ofreference in the several figures indicate the same parts.

The invention is illustrated in connection with the type casting and composing machine of Patent No. 625,998 dated May 30, 1899, with the improvements of Patent No. 749,149, dated Jan. 12, 1904 applied thereto.

It will suffice, for present purposes, to designate some of the principal elements of the prior patented machine, such as the die case 1, its carrier 2, and support 3; the centering pin lever 4 and the two centering mechanisms connected with and controlling the movements of the die case and its carrier, respectively, each of said mechanisms including a primary gage represented byfifteen serially arranged and equally spaced stop pins 5 or '5 of which each, save that at one end of the series, is separately controlled by a piston and an air duct leading to one of a series of ports in the tracker bar (not shown) of the paper tower; a primary positioning mechanism comprising oppositely movable jaws 6 or 6* one of which engages a stop pin whenprojected into its path and the other closes upon the engaged jaw; a secondary gage or stop bar 7 or 7 interposed between and brought to position by the closing jaws 6 or 6",Said stop bar being furnished with a series of teeth 8 or 8 spaced to correspond with the spacing of the matrices in the die-case and engaged by a locking bar 9 or 9", the latter engaged by one of two levers 10 or l0 acted on by one of a pair of springs 11 for advancing and by a cam controlled pusher 12 or 12 for retracting said bolt, and a secondary positioning mechanism represented by oppositely movable jaws 13 or 13", closing on stop bar 7 or 7" and upon a translating device 14 or 14*, the latter coupled with the performing member represented in this case by either the die case or its carrier. This is the normal equipment for dealing with a die-case containing fifteen rows of fifteen matrices 'each, the primary and secondary gages of the positioning or centering mechanisms each being equipped with admeasuring devices for fifteen equally spaced stations.

YVhatever the unit of this measure it is obvious the signal responsive members of the primary gage couldonly indicate stations separated in units or multiples thereof. As hereinbefore stated the unit of measure adopted for the commercial machines and the matrices therefor is two tenths of an inch, while that of the matrix can, according to Patentv No. 980,959, be increased to four tenths inch which is the next larger size matrix available.

For some of the larger fonts and under special circumstances less than a two unit increase in the size of the matrices in one or both directions will suflice to accommodate the character, and if a fractional increase can be made the capacity of the die case will be increased accordingly. Thus with the two unit abnormal matrices, but eight matrices can be associated in any one line or column, to wit, seven of two units and one of one unit, dimensions, whereas with a one half unitincrease, which is ample for some of the largerpoint sizes, ten matrices of one and a half units dimensions can be associated together in a line or column whose .normal measure, as indicated by the primary gage, is fifteen units in length.

In the example diagrammatically illustrated in Fig. 2, the die case is equipped with ten rows of matrices, whereof seven rows are arranged in fifteen equally spaced columns and the remaining. three rows in ten equally spaced columns; otherwise stated, the matrices are all one and one-half units inch) columnwise, those comprising each of seven rows, being one unit inch) in width, and those of each of the three remaining rows being one and one-half unit inch) wide.

It is obvious that the normal centering mechanism is incompetent to deal with such a die'case (other than for effecting the adjustments pertaining to the lines of fifteen matrices each which correspond with the pitch or. measure, of the signal responsive gage) owing to the fact that the pitch or measure differs from the normal established by the primary and secondary gages. The problem thus presented involves the utilization of the signal responsive gaging mechanism for selectively eifecting adjustments pertaining to two different series, the one normal to said gaging mechanism and the other varying therefrom in a predetermined degree; and the solution is found in the addition of an auxiliary positioning means. for automatically varying the adjustments effected through the normal centering mech-' secting-linesf Said auxiliary positioning means is in the form of a rack 15 or 15 formed on an extension of or otherwise suitably coupled with the corresponding stop bar or gage 7 or 7", and a positioning member or bolt 16 or 16 guided on the frame and adapted to engage the inclined teeth of the rack for shifting the latter by an amount equal to the diflerence, if any, between the position indicated in relation. to the normal matrices and that occupied by the abnormal matrix to which the same signal responsive member is assigned.

As shown the teeth 17 of racks 15 and 15 differ in pitch from'the normal locking teeth 8 or 8 in. the proportion of ten to fifteen thusdividing the movements of adjustment as affected by each stop bar into ten equal intervals as compared with the fifteen rep-- resented by the normal teeth 8 or 8*. It results from this arrangement that when either stop bar 7 or 7" is adjusted to the positions indicated by its signal responsive gage, teeth 17 of its rack 15 or 15 will be at times out of register with positioning member 16 or 16", and if when. so out of register the mem ber 16 or 16*, is advanced it will engage the inclined side of the nearest tooth 17 and operate thereon to shift and thus vary the position of the stop bar to accord with the station in the auxiliary system represented' by the interval between the engaged teeth. Thus with a layout such as indicated in Fig. 2 wherein the stations columnwise are equally spaced but abnormal and the stations linewise are normal for seven lines and abnormal for the remaining three lines, the auxiliary positioning mechanism will be utilized for effecting columnwise adjustments, the normal centering mechanismvfor seven lines and the auxiliary for the three remaining iines, the position of adjustment in either direction being primarily indicated and determined by the si nal responsive members of the gages. In t is instance, where the auxiliary positioning means is applied to the stop bar, it is required that the action of the normal. locking bar 9 or 9 should be suspended when said auxiliary is to be utilized for varying the position and that the action of the auxiliary positioning mechanism should likewise be suspended. when normal adjustments are to be effected. Mechanism for selectively efiecting these actions is shown. and will next be described.

Each positioning member 16, 16 is provided with retracting means (represented by spring 18 or 18") and with projecting means (represented by piston 19 or 19*, working in a cylinder 20 or 20*)-the member 16 pertainin to the column 'or horizontal series of s'tations (Fig. 2) being connected directly. to its piston 19 and the other, as matter of accommodation, indirectly connected to its piston 19 through a lever 21.

bers 16 and 16 'sponsive means the form of a piston Opposite lever 10 of the locking bar 9, pertaining to the horizontal positioning mechanism, (Fig. 2) is a motor in the form of piston 22 Working in a cylinder 23; and connected through a link 24 and lever 25 with the locking bolt 9 of the vertical positioning mechanism is, a working in a cylinder 23*, the arrangement being such that when pressureis admitted to either cylinder it will overcome the propelling spring 11 of the corresponding looking bar 9 or 9 and hold the latter out of contact with its stop bar 7 or 7*.

Whenever a transfer from the normal to the auxiliary .positioning mechanism is required to be made it is only necessary to admit pressure to the cylinder 23 or 23* corresponding with the direction of movement to be controlled, thereby throwing locking dog 9 or 9* out of action, and, at the properv point in the cycle, admit pressure to the cylinder 20 or 20*, to advance the positioning member 16 or 16, and thereby shift the stop bar from the position directly indicated the signal responsive gage to that indicated by the auxiliary gage acting in conjunction therewith.

Inasmuch asthe adjustments or readjustmen-ts performed by the positioning memare supplemental or auxiliary to the adjustments directly'produced by the normal signal responsive devices, it is necessary. that they be performed in the interval between and the final seating of the selected matrix-upon the mold and when the spacing in either direction is not uni form "but irregular, being inpart normal and in part abnormal, as in the example illustrated herein, it is more convenient that automatic means be provided for effecting.

the transfer from the one system tothe other. This 'can readily be accomplished by various mechanism of which a preferred form is illustrated and will now be described.

In a frame 35 detachably. secured-to the main frame of the machine is formed a pressure chamber 36 communicating through a pipe 37 with a source of air pressure, said pipe containing a control cook 38; Opening toward and into chamber 36 are two valves 40, 40*,

The opposite arm .of lever 41 is arranged to I contact with the centering pin lever 4, and

is advanced to contact therewith, when in action, by a' pressure motor, preferably in der 4.4:, the latter communicating with the pressure supply, as by being connected to chamber 36, so that when the system is out out by means of cook 38 lever 4 will be relieved of the added pressure. Lever'42 carries a movable interponent 46 in the 'formof a rod 47 Working through a bearing in one similar piston 22 the action of said signal re-- the stems whereof are en 'gaged, respectively, by levers 41 and 42.

43 Working in a cylining such that as lever 4 is moved to elevate the centering pin, levers 41, .42 will be operated to unseat the valves or open the passages controlled thereby, this action taking place during the opening movement of jaws 6, 6", after locating stop bars 7 7", and before the closing movement of jaws 13, 13 on their stop bars, whereby theproper timing of the auxiliary positioning movement is insured.

. Cylinders 20 and 23 are connected through a pipe 49 with a chamber in rear of valve 40", and, but for the fact that the abnormal series of movements affected by the positioning member 16" pertaining to the vertical series of adjustments are uniform, a similar arrangement might be applied in connection with valve 40', but inasmuch as this series, although abnormal, is uniform and in consequence thereof is used, when at all, to the exclusion of the normal adjusting series, cylinder 23" is connected through pipe '50 with pressure chamber .36, while cylinder 20 is connected by pipe 49" on the other side of valve 40. By this means when the auxiliary positioning mechanism is connected-up for action the locking bolt 9 of the vertical adjusting mechanism, Fig. 2, will be locked out of action through pressure in cylinder 23 instead of being withdrawn at each advance of the associated positioning member 16".

Where, as in the present case, both series of adjustments-normal and abnormaL-are interchangeably employed, the shift from onerto the other can be automatically effected through the agency of the companion auxiliary positioning mechanism and it is for this purpose the movable interponent 46 is introduced. Rod 47 is connected to one arm of a lever 51 whose opposite arm-carries a pivoted angular link 52 One arm of link 52 carries a roller 53 adapted to ride npon stop bar 7 and the latter is recessed as at 54 to receive the toe of said link when the stop bar is adjusted to correspond with the lines of matrices of normal width. In the example illustrated, wherein the first seven lines of matrices are operated on by the normal positioning mechanism for horizontal adjustment .(Fig. 2.) the slot or recess 54 pertaining to the vertical system terminates lengthwise of the stop bar over the space covered by its movement for the first seven lines of matrices counting from the bottom in Fig. 2 and measured with relation to the toe of link'52. -Whenthe stop bar is 10- cated in any one of the seven stages or positions indicated,'roller 53 will ride on the surfaceof the step bar and the toe of said link will be projected into recess 54, which position will be maintained by a spring 55 acting on lever 51. Under these circumstances rod 47 will be shifted to clear shoulder 48 of lever 41 in consequence whereof lever 42 will not be engaged and valve 40 remaining seated the auxiliary positioning devices pertaining thereto will not be brought into action and the normal positioning devices for the horizontal movement will continue in action affording fifteen degrees of adjustment for the seven lines referred .to. When, however, the movement of the stop bar is increased to cover any of the three upper lines of matrices, Figs. 2

and 3, the right end of recess '54 engaging the toe of link 52 will elevate the latter to the level of the surface of the stop bar, thereby tilting lever 51 to project the interponent into the path of shoulder 48 so that upon the next movement of lever 4 valve 40" will be moved to admit pressure to cylinders 20, 23, and thus apply the auxiliary positioning mechanism in effecting horizontal adjustment of the die case in connection with either of the three upper lines of matrices indicated in Fig. 2. Upon the return' of stop bar 7 x to the territory covered by the first seven lines of matrices, link 52 will again enter recess 54 withdrawing interponent 46 and restoring the control of the normal centering devices.

In the example illustrated, wherein the ratio between the abnormal and normal units of measure is as one and a half to one the alternative admeasuring devices are so correlated as that when the performing 'member, a. e., the stop bar, is brought to the position indicated by the first or fixed pin of the primary gage to register the first in the normal series of fifteenunits, the positioning member 16 or 16" will stand midway between the first and second teeth 17--of rack 15 or 15" to establish the first of the .ten units of the abnormal or auxiliary system. As thus arranged when the auxiliary system is connected up and in action the second, fourth, fifth, seventh, eighth tenth, eleventh, thirteenth and fourteenth stop pins, counting the fixed pin as one, will 10- cate the stop bar in proper relation to positioning member 16 to caus it, when operating, to effect adjustments corresponding with the second, third, fourth and so on up to the tenth degree, respectively, in the abnormal or auxiliary system.

A brief summary will suifice to explain the operation.

When a die case containing only matrices of normal dimensions are employed control cock 38 is closed to cut out the auxiliary system and the machine operates in the usual well known manner. When a die case equipped with the abnormal sized matrices is applied to the machine cock 38 is opened with the result that the locking bar of the centering mechanism pertaining to the vertical series of positions, Fig. 2, is locked out of, action through the admission of pressure to cylinder 23*. The position of the die case necessary to bring any one of the matrices into position above the mold measureo on the scale of the abnormal systembeing indicated by a signal bringing into action, 2'. 0., projecting the appropriate stop pins, the stop bars are positioned accordingly, thereby effecting a preliminary location of said stop bars in such relation to the auxiliary positioning members 16 or 16 .asthat when the latter are projected, they will en ter between. the teeth 17 of the admeasuring racks 15 or 15 and, if necessary, shift the latter in one direction or the other in an amount corresponding to the difference between the station indicated by the stop pin and that indicated by the positioning member in its relation to the two adjacent teeth of rack 15 or 15 time being located. The projection of the positioning members is effected through the opening of valves 40, 40*, or either of themaccordingly as the auxiliary system is applied for effecting adjustments in one or the other or both directions.

vVhere both normal. and abnormal adjustments are applicable to the movement in one direction, for example, horizontally in Fig. 2, selection is effected through link 52 and interponent 36 and the timing through levers 41 and 42.

Although illustrated herein in connection with a point-to-point centering mechanism embodying both primary and secondary gaging and positioning mechanisms, according to Patent No. 625,998, the invention is not limited thereto, but is applicable to other forms of mechanism, such, for example, as that disclosed in our application Serial No. 7 09,468, filed July 15, 1912, wherein the secondary gage is replaced by a movable member connected directly to the performing member, such as the die case, its carrier, etc., and one of the positioning mechanisms herein shown, is entirely dispensed with.
