Definitions
- This invention relates generally to high speed printing mechanisms employing rotary type carriers operating to produce a line of print within a cycle of rotation, the invention relating more particularly to the type carrier and means for mountingsame in various orientations relative to a line of type hammers so as to render-the mechanism adaptable for both parallel and serial readout modes of operation.
- Printing mechanisms of the sort hereinabove referred to have customarily been designed with hardware components, particularly the type carrier, designed for either one or the other of the two basic modes of operation, i.e. parallel read-out or serial read-out.
- parallel read-out is intended to denote that mode of operation wherein the control information'is made available for all print columns simultaneously so that, for example, if the entire print line were to consist of the" same character, all type hammers would be fired simultaneously.
- serial read-out is intended to denote that mode of operation wherein the control information is made available to the respective print columns serially so that, for the same example, the successively disposed type hammers arranged across the printing line will be controlled to fire one after the other with no two print hammers firing at exactly the same time. It will of course be evident that a basic distinction in the design of equipment for the respective modes of operation lies in the different orientation of a row of type faces extending across the type carrier in relation to the row of respective type hammers associated therewith.
- type carriers for use solely in accordance with one or the other of these separate modes of operation.
- the type carriers are" designed with rows of type faces extending across the carrier in a line parallel with the carrier axis.
- type carriers For serial read-out systems, type carriers have been designed with type faces extending in rows following a slightly spiralled configuration so as to provide the required delay, from one column of type faces to the next, in the time that the type faces of the respective columns are registered with their respective type hammers. It will of course be apparent that the necessity for designing the type carrier specifically for one form of operation or the other increases the cost of manufacturing equipment of this class over what would be the cost if the same type carrier could be utilized in both modes of read out.
- the present invention overcomes this difficulty by providing means whereby the same type carrier may, by simple adjusting procedures, be adapted to operate either in a parallel read-out or a serial read-out system.
- This adaptability is achieved by making provision for adjusting the type carrier supports at each end thereof so as to enable the orientation of the carrier axis to be varied relative to the line of type hammers depending upon which mode of operation is desired.
- the adjustable support for the type carrier enables the axis of the carrier to be tilted or skewed in either of two possible directions, i.e. perpendicular or parallel to the plane in which the type hammers are fired, either direction of adjustment serving to achieve the same result.

and Orland F. Bergere, Fairfield, Conn., assignors to Sperry Rmd Corporation, New York, N.Y., a corporation of Deiaware Filed Sept. 10, 1962, Ser. No. 222,342 9 Claims. (Cl. 101-93) This invention relates generally to high speed printing mechanisms employing rotary type carriers operating to produce a line of print within a cycle of rotation, the invention relating more particularly to the type carrier and means for mountingsame in various orientations relative to a line of type hammers so as to render-the mechanism adaptable for both parallel and serial readout modes of operation.
Printing mechanisms of the sort hereinabove referred to have customarily been designed with hardware components, particularly the type carrier, designed for either one or the other of the two basic modes of operation, i.e. parallel read-out or serial read-out. The term parallel read-out is intended to denote that mode of operation wherein the control information'is made available for all print columns simultaneously so that, for example, if the entire print line were to consist of the" same character, all type hammers would be fired simultaneously. The term serial read-out is intended to denote that mode of operation wherein the control information is made available to the respective print columns serially so that, for the same example, the successively disposed type hammers arranged across the printing line will be controlled to fire one after the other with no two print hammers firing at exactly the same time. It will of course be evident that a basic distinction in the design of equipment for the respective modes of operation lies in the different orientation of a row of type faces extending across the type carrier in relation to the row of respective type hammers associated therewith.
Heretofore, it has been necessary to design type carriers for use solely in accordance with one or the other of these separate modes of operation. For parallel read-out systems, the type carriers are" designed with rows of type faces extending across the carrier in a line parallel with the carrier axis. For serial read-out systems, type carriers have been designed with type faces extending in rows following a slightly spiralled configuration so as to provide the required delay, from one column of type faces to the next, in the time that the type faces of the respective columns are registered with their respective type hammers. It will of course be apparent that the necessity for designing the type carrier specifically for one form of operation or the other increases the cost of manufacturing equipment of this class over what would be the cost if the same type carrier could be utilized in both modes of read out.
read-out control of the type. hammers.
The present invention overcomes this difficulty by providing means whereby the same type carrier may, by simple adjusting procedures, be adapted to operate either in a parallel read-out or a serial read-out system. This adaptability is achieved by making provision for adjusting the type carrier supports at each end thereof so as to enable the orientation of the carrier axis to be varied relative to the line of type hammers depending upon which mode of operation is desired. The adjustable support for the type carrier enables the axis of the carrier to be tilted or skewed in either of two possible directions, i.e. perpendicular or parallel to the plane in which the type hammers are fired, either direction of adjustment serving to achieve the same result. By providing means for effecting such an adjustment, the cost "Ice of manufacturing equipment which is capable of operation in both. parallel and serial read-out systems is considerably reduced.
It is therefore the principal object of this invention ably orienting the axis of the type carier r elative to the associated type hammersso as to adapt the mechanism for either parallel or serial modes of operation.
Further objects of the invention together with the features contributing thereto and the advantages accruing therefrom will be apparent from the following description when read in conjunction with the drawing wherein: FIG. 1 is a left. hand sectional view of the type drum and associated type hammer mechanism of a'high speed printer embodying the present invention.
FIG. 2 is a'view of the type drum mounting meanson theright hand side.
FIG. 3'is a view ,of the type drum mounting means i on the left hand side. 7
PEG. 4 is a front view, taken along line 44 of FIG. 1, of the type drum shown as mounted'for parallel FIG. 5.is a plan view, taken along line 5-5 of FIG. 1, of the drum shown as mounted for paralell'readout. 7
FIG. 6 is a front view, similar to FIG. 4, of the drum shown as mounted in accordance with one manner of ad-" justment for serial read-out control of the type hammers. 1 FIG. 7 is .a plan view, similar to-FIG. 5, of the drum shown as mounted in accordance withanother mannerof adjustment for serial hammers.
With reference-to FIG. 1, the mechanisms by which printing is effected includse a type carrier in-the form of a drum 10 suitablekeyed to a continuously rotating shaft 11, the shaft rotating in a counter-clockwise direction in the present instance so as to serially advance type faces arranged columnarlyaround the pe-v riphery of the drum into print position in registration wih an associated type hammer 12. A print receiving medium 13, which may be paper or other suitable material, is disposed between the head of the type hammer and the type drum, the said medium being supported and fed' line spacing direction by any suitable means, not shown. Disposed and suitably fed between the print receiving medium and the type drum is a marking transfer medium 15 in web form, which may be impregnated either with ink, carbon,'or the like, for transferring the image of each character type face to the surface of the print re- 5 ceiving medium when a type hammer 12 is actuated .to impact the print receiving medium and the marking transcharacter type face to be transferred through the mark- 7 ing medium 15 and reproduced on the print receiving medium 13. The type hammers are slideably supported for firing movement by a transverse hammer guide bar 25 which extends across the machine from one side to another a distance at least the length of the drum and is read-out control of the type there is one shown in FIG. 1, are supported by the bar '25 in a row extending horizontally across the machine with the heads of the type bars aligned along a horizontal line which will hereinafter be referred to as the firing line. It will also be seen that the firing stroke of all the type hammers from the firing line into printing impact with the type drum is guided along a substantially horizontal trajectory lying within a plane which is common to all.
the type hammers and which will hereinafter be referred to as the firing plane.
As can be seen by reference to FIGS. 2, 4 and 5, the right hand end of the type drum drive shaft 11 is rotatably mounted in bearings 31 which are of the self-aligning type to allow a limited amount of shaft deflection relative thereto. The bearings, along with a cooperating thrust-absorbing spring 34, are fitted into a suitably recessed circular housing formed in a shaft support cap or block 32 which serves as a journal box for the shaft.
for reasons which will be hereinafter more fully explained. The set screw 37, which is threaded into the casting 36 at the bottom of the U-shaped opening or seat, supports the bottom edge of the block 3?. and is effective for adjusting the block in a substantially vertical plane perpendicular to the type hammer firing plane heretofore defined. The set screw 38 is threaded into the frame casting at the side wall of the seat 35 so as to bear against the side of the block thereby being effective for adjusting the position of block 32 within said seat in a} substantially horizontal plane parallel to the type hammer firing plane aforesaid.
'The block 32 is secured in its adjusted position by means of bolts 39 fitted in oversized bores 49 formed in the side flanges 33 which overlap the side walls of the seat, said bolts 'being threaded into the frame casting to firmly retain the plate Within the seat.
As shown in FIGS. 3, 4 and 5, the left hand end of the type drum drive shaft 11 is supported in a manner similar to that just described for the right hand end by means which includes self-aligning bearings/t1 fitted into a circular recess in an open support block 42 formed with position of the block 42 in a plane parallel to the type hammer firing plane. Clamping bolts 49, engaging in overslzed bores 59 formed in the outer overlapping flanges 43 of the block 42 and threaded into the frame casting 46, serve to securely retain the block in its adjusted position 7 within the seat 45 formed in theframe casting 46.
To adapt the type drum for use in parallel readout systerns, the set screws 37, 38 and 47, 48 are setso as to orient the axis of the carrier i.e. shaft 11, parallel to the type hammer firing line. The type drum may be adapted for use in serial read-out systems in either of two ways. One way of adapting the drum for serial read-out is by adjusting the set screws 37, 47 so as to elevate one end of the drum and lower the other end of the drum which has the effect of skewing the axis of the drum relative to the type hammer firing line within a plane perpendicular to the firing plane. 'Another way of adapting the type drumfor a serial read-out system is by adjustment of the set screws 38, 48 so as to dispose one end of the drum closer to the firing line and the other end of the drum more removed from the firing line thereby, in effect, skewing the axis of the drum relative to the firing line withina plane parallel to the firing plane.
As indicated in FIGS. 4 and 5, character type faces 51 are disposed over the surface of the type drum in a pattern of intersecting rows and columns, each row containing a typeface for the same character and extending longitudinally of the drum along a line parallel to the drum axis. Each column of type faces includes one for each of the several characters which may be printed by the mechanism and extends circumferentially around the drum along a line perpendicular to the drum axis. The
arrangement shown is the checkerboard design wherein each row contains a type facefor every other column with the type faces for each'separate character being contained in two adjacent rows relatively offset one column from the other. .It will be understood, however, that this checkerboard array of type faces is shown by way of an example and is not essential for carrying out the inventive concept herein disclosed. It will also be understood that a separate type hammer l'2 is provided for each column oftype faces 51 on the drum 10.
FIGS. 4 and 5 illustrate the orientation of the drum 10 relative to the type hammers 12 when the drum mounting meansheretofore described are adjusted so as to adapt the drum for use with parallel read-out control of the type hammers 12. In this adjustment, the drum axis is disposed so as to be parallel with the type hammer firing line. When thus adjusted, the type drum as it rotates, as best seen in FIG. 4, operates to carry all type faces within a row simultaneously into registration, at print position, with the print hammers 12.. When the axis of the type drum is disposed parallel to thefiring line, the surface of the drum, as can be seen in the plan View of FIG. 5, along its entire length is equidistant from the several type hammers 12 so that the distance required for a type hammer to move from the firing line into printing impact, i.e.' the length of the firing stroke, is the same for all type hammers. Thus, it will be apparent that, when the type drum axis is oriented parallel to the firing line, the simultaneous firing at uniform velocity of selected type hammers in accordance with parallel read-out techniques will drive the selected type hammers into printing impact at the same instant since they all travel the same distance from the firingline. It will of course be understood that the firing of the selected type hammers is timed to make allowance for the travel time of the type hammers into printing impact so as to cause the selected hammers to simultaneously impact their respective type faces at the instant the row of type faces is carried into printing position.
FIG. 6 is a front view similar to FIG. 4, but illustrating an adjusted orientation of the type drum, in accordance with one form of adjustment, for adapting the type drum p the axis of the type drum relative to the type hammer firing line within a plane parallel to the firing plane of the type hammers 12. When in the position as shown in FIG. 6, it will be apparent that, as. the type drum rotates, the type faces 51 of a row will be carried into registration, at print position, one after the other, serially,
starting with the left hand columns. The degree of skewing depends upon the velocity of the type drum and the read-out rate and is calculated so as to synchronizethe serial registration of type faces within a row at print position with the serial read-out rate controlling the type ham: mers so that the firing of any type hammer along the row will cause it to impact the type face at the instant the.
type face is registered at print position. It will of course be understood that the sequential order in which the several type hammers are controlled during the serial readout proceeds from left to right across the row of type hammers so as to thereby correspond to the order in which the type faces of a row are carried into printing position.
The plan view of FIG. 7 illustrates another manner of orienting the type drum relative to the type hammers 12 for adapting the type drum to serial read-out systems. In this case the set screws 38, 48 are adjusted so as to deflect or skew the axis of the type drum within a plane parallel to the firing plane of the type hammers. This has the effect, as shown in FIG. 7, of disposing the right hand end of the type drum closer to the row of type hammers and the left hand of the drum farther away from the row of type hammers. This adjustment results in varying the length of the firing stroke for the several type hammers in the row with the firing stroke for the hammers on the left hand side being increased in. length and gradually iminishing in length in left to right order along the row of type hammers. It will of course be evident that if the several type hammers are fired with uniform velocity, which is the case, those which are required to travel the greater distance from'the firing line into printing impact, i.e. have the longer firing stroke, will take a correspondingly longer time interval from the moment of firing until they reach printing impact, This time differential between the firing stroke time of the several type hammers compensates for thetime lag in the read-out rate so that as a row of type faces is carried simultaneously into print position all of the type hammers which are sequentially fired to print the corresponding character will impact the respective type faces of the row simultaneously. The degree of skew of the carrier axis is calculated so to to provide a time differential between the firing stroke time of adjacenttype hammers which is equal to the time lag between successive columnar control intervals in the read-out cycle.
From the foregoing it Willbe apparent that the invention provides means which by simple adjustment procedures enables a type carrier to be adapted for both parallel and serial read-out systems. While the invention has been shown and described in what is considered to be a preferred embodiment, it will of course be understood that changes in form could be made without departing from the spirit of the invention, and it is therefore intended that the invention be not limited to the exact form herein shown and described nor to anything less than the whole of the invention. as hereinabove set forth and as hereinafter clm'med.
