ADJUSTING OR CENTERING MECHANISM FOR TYPE-MACHINES..-

SPECIFIGA'IION forming part of Letters Patent No. 782,536, dated February 14, 1905.

I Application filed July 11, 1904. Serial No. 216,163.

To all whom, it may concern:

Be it known that 1, JOHN SELLERS BANcRorr, of Philadelphia, in the county of- Philadelphia and State of Pennsy tain new and usefuling chines; and I do hereby lvania, have invented cer- Improvements in Ad ustor Centering Mechanisms for Type-Madeclare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming a part of this specifi: cation, and to the figures of reference marked thereon.

This invention relates to improvements in ad usting or centering mechanisms for typecasting and other machines wherein the positioning of a movable case, its carrier, the

element-such as the diemold-adjusting device, -or

other translatable memberis governed by perforations in arecord-strip and effected by a direct movement from one position to another after the manner disclosed in Patents Nos. 625,998, 674,37 6, and 749,149.

As heretofore constructed machines of the class mentioned have been equipped with a primary gage in th e form of a plurality of stop-pins serially arranged, a primary positioning mechanism in the form of oppositelymovable jaws, of which latte-r one contacted with the selected ,pin of the primary gage to determine the closed position of thejaws, a

secondary gage mov ed to position by the jaws of the primary positioning mechanism and there looked, a secondary positioning mechanism,including opp ositely-movablejaws,con-

sive positions for and a control system intermediate the member to be adjusted,

the governing element and the primary gage for sepathe primary gage.

action the members of Each position or station in the series of movements provided for was represented by a separate pm in the primary gage, and each pin,

with the exception of the are represented by a last inthe series, was provided with a separate control mechanism or line'of communi- 5 cation with a section 'of the record-strip, so that a perforation occurring in that section would bring into action the corresponding pin of the primary gage. To each positioning perforation was assigned a section of the rec- 5 5 ord-strip, and the width of the latter was dependent upon the number of individual control elements of the primary gage. Thus the centering mechanism for the die-case for positioning the latter by a two-way movement of 6 fifteen degrees in each direction involved the use of twenty-eight movable gaging members or stop-pins, fourteen for each direction, with separate control devices and a governing perforation for each member. This required that the record-strip should be of such dimensions as to contain at least twenty-eight sections for receiving the positioning signals or perforations and that the punching-machineshould be equipped with a like number of punches for producing the signals.

Now the principal ob ect of the present invention is to effect a material reduction in the dimensions of the record-strip and incidentally to simplify the construction of the primary gagmg and control mechanisms by the employment of a signal and control system wherein the various positions of adjustment instead of being represented by a correspond ing series of differently-located perforations limited number of such perforations employed singly and in various combinatlons to represent successive or different positions.

To this end the invention consists in the con- 8 5 struction and use of a composite gaging mechanism, including a plurality of gaging m'em-.

bers of difierent capacities arranged and adapted for separate or conjoint action, each gage member being provided with a control means governed by a perforation in the record-strip,

so that any one or more of said gage memhere may be actuated and the gage thus set to correspond with the position represented by the dimension or capacity of any individual member or by the sum of the capacities of any two or more members, all as hereinafter fully described, the novel features being set forth in the appended claims.

In the accompanying drawings, illustrating tioning mechanism. Fig. 3 is a top plan view of the gaging mechanism. Fig. 4 is a trans verse and Fig. 5 is avertical longitudinal sec tion through the gage.

Thesame numerals desigate like parts in the several figures.

The invention is illustrated as adapted to the die-case centering and mold -adjusting mechanisms of the type casting and composing machine of Patent No. 625,998, wherein it supplants the primary gage in each of the two adjusting or positioning mechanisms. It will suffice for present purposes to designate certain of theprominent elements of said machine, reference being had to the patentmentioned for a more detailed description. These are the paper-feed mechanism, controlling the movements of the perforated record-strip l, and its application to the ports 1", leading to the control devices, the die-case 2 and its carrier 3, arranged for independent adjustment on intersecting lines and operated upon by the two positioning mechanisms to center the matrices above the mold by a direct movement from one to another, the secondary positioning mechanisms (represented by jaws 4) for shifting the die-case and its carrier and the mold-adjusting devices, the secondary gages 5 for determiningthe closed position of jaws at, and the primary positioning mechanisms (represented by the oppositely-movable jaws 6) for shifting the secondary gages and depositing them at any of a series of predetermined stations. The stations assigned to the secondary gages correspond to the different positions of adjustment permitted the diecase or other adjusted member, and it is the special function of the primary gage to designate the successive positions of adjustment effected by the members of the centering on positioning system. The new controlling or gaging system is illustrated in a preferred form of embodiment as applied to each of the two positioning systems, whereit supplants the series of stop-pins and control devices of the prior machine; but as the mechanisms so applied are substantially duplicates a description of one set will su'ffi'ce for both.

To thetop plane of the casting-machine .is detachably secured a supplemental frame 7 provided with guides or ways 8 to receive and sustain the oppositelyrmovable jaws of the primary positioning mechanism. One of said with a contact jaws is furnished surface 9,-located to oneside of,

preferably latter,

or gaging below, the plane of movement of the opposite jaw and in line with a fixed contact-surface or abutment 10, carried by frame 7. This fixed abutment, preferably in the form of a screw or equivalent means for initial adjustment, corresponds in position with the fixed stoppin of the prior primary gage and, like the serves to define one extreme of the series of-stations or positions of adjustment to which the system is adapted. In the example given the system corresponds with that of the prior patent-that is, it embraces a series of fifteen equally-spaced stations, of which the abutment represents the last or fifteenth and serves as a datum-line for locating the other stations.

Supported in position to be, interposed between the relatively movable gaging-surfaces 9 and 10 is what is herein termed a differential permutation-gagethat is, one comprising a plurality of individual gages or interponents of relatively difl'erent dimensions or capacities adapted to be interposed separately or serially in combinations of two or more between said gaging-surfaces to admeasure their relative positions.- In the preferred form of embodiment herein illustrated the gaging members or interponents of this composite gaging mechanism are represented by four gage-blocks 11 of one, two, four, and eight units capacity, the unit in this case being the'interval between adjacent stations in the series. It is of course understood that the dimension of the unit and relative sizes of the individual gages may be varied to suit the particular system employed and that the capacity of the gage as a whole can be increased or diminished by the addition or omission of individual gages; but as applied to the present system it will be found that with four differential gages of the dimensions given all of the stations designated by the fourteen movable stop-pinsof the prior machine can be accurately and positively gaged. Thus the fourteenth station, one unit removed from the fixed abutment, can be located by the interposition of the one-unit gage between the abutment and movable jaw 6. The thirteenth station can be located by the interposition of the two-unit gage, the twelfth by the one and two unit gages in combination, the eleventh by the four-unit gage, the tenth by the one and four unit gages, the ninth by the two and four unit gages, the eighth by the one, two, and four unit gages, the seventh by the eightunit gage, the sixth by the one and eight unit gages, the fifth by the two and eight unit gages, the fourth by the one, two, and eight unit gages, the third by the four and eight unit gages, the second by the one, four, and eight unit gages, and the first by the two, four, and eight unit gages. The significance and advantages of such a system wherein gages of: different dimensions are adapted for use singly and serially in combinations of two or- I jaw 6, carrying contact-surface 9, in order that it may be moved into contact with the fixed abutment or an intermediate gage to.

measure the movement of said'jaw and arrest 1t 1n designated position, to whlch end said gages are carried on arms 12, disposed in dif-1 ferent planes and each provided with a sleeve 13 or equivalent support engaging one of a series of parallel guides or rods 14. Each rod 14 is provided with a limiting-stop 15 for positioning its gage when retracted, at which. time the several gages are supported in alme- 'ment and below the plane of movement of contact-surface 9 by restingupon the face of frame 7. To effect and insure the return of the gages to initial position after having been elevated into alinement with the jaw and moved by the latter toward the fixed abut: ment, the two, four, and eight unit gages '11 are each provided with a shoulder 16in a po-.

sition to be engaged by one of a series of shoulders 17 on a rod'18, attached to andcarried by the movable jaw 6. The shoulders 16 and 17 for the respective gages are located in different planes, so that as the aw advances toward the fixed abutment the shoulderson' rod 18 will clear any of the gages that may happen to be elevated and upon the return of the jaw each shoulder 17 will engage and draw to initial position the corresponding gage.

Each gage 11 is provided with control means whereby it can be moved into gaging positionthat is, in the present instance into alinement with movable contact-surface 9 and the fixed abutment and with any other gage so moved into alinement. For this purpose a piston 19, provided with aretracting-spring 20 and working in a cylinder 21, is located beneath each gage in position to elevate the latter into the planeof contact-surface 9 when pressure is admitted to the cylinder, a shoulder 22 on the piston-rod serving to limit the advance of the latter and prevent contact with the jaws. The first or one-unit gage 11 may be attached to and guided by its piston; but the others merely rest upon the ends of their piston-rods, so that they are free to move thereon when engaged by contact-surface 9. The pistons as applied to these movable gages are preferablylocated beneath the ends thereon nearest the fixed abutment, in order that each may remain in contact with and support its gage when the latter is moved to an extreme position in either direction, to which end the gages are disposed in sequence in; the

to cover all the required stations, but would be permitted a movement of seven units, if

vused alone, andthus be carried beyond its 1 control-piston unless additional or other means were employed to'prevent such action.

Each cylinder 21 is connected, through a passage 23, with one of the induction-ports of the paper-feed mechanism, through which i their action is governed by the perforations in the record-strip.

From the foregoing description it is apparent that the composite gaging mechanism, with its fixedvabutment or datum-line and separate gages of difierent dimensions adapted for separate and conjoint use in various combinations, is entirely competent to measure or designate each of the fifteen stations required for positioning the die-case or other movable part in one direction and that but four control devices are required for setting the gage for any position within its capacity, which means, as applied tothe machine illustrated, that but eight induction-ports and corresponding, perforations in the record-strip are required to compass the thirty adjustments previously effected through the medium of twenty-eight ports and perforations, thus reducing thearea of the recordstrip assigned to these adjustments to less than one-third that required by the primary gages of the prior machine.

The new gaging system is admirably adapted for expansion to cover 'a larger range of stations or positions than is required in the machine illustrated as, for example, in the mold-dimensioning system ofapplication Serial No. 191,382the number of possible com-i binations being greatly increased by the .addition of each gaging member with its single control means and governing perforations.

Not only does the improved gaging systemoperate to materially diminish the size of the record-strip w-ithouta corresponding change in its-capacity; but it contributes to a simplification of the r.ecord-stripperforating mech-- anism by reducing the number of punchesrequired for forming the designating perforations orv signals.
