PRINTING MACHINE.

Application led April 2, 1927.

This invention relates to printing machines of a character in which the type are set iii a torni or way with which the inachine is provided which form is supported in a head pivoted to swing on a hor'moniial axis from the printing to non-printing position as is set forth and described in our pending application for Letters Patent of the United States, Serial No. 149,335.

The object of this invention is to provide a new and improved type impression indicator brought to position over the sheet to be printed when the head has been moved to non-printing position tor the setting of the type and thus automatically indicate toi the operator while setting the type the position that the subsequent type impression will occupy on the sl'ieet.

A feature ot this invention is iii the, provision of a pair ot slides movable on a part ot the type carrier andv to engage opposite ends ot a set line of type and carrying arms practically in alignment with the opposite ends ot the line ot' type and' the provision ot' threads or cords extending` between the arms in parallel relationv which in conjunction with the arms indicate the space the type impression will occupy on the sheet.

Another feature ot the invention is in the provision ot cords and movable arms in such an arrangement and relationship that the arms may be moved to any position longitudinally ot the type holder or way with the cords running freely through the arm ends and eliminating necessity of changing of the cords or length of the cord for the various distances apart the arms may be placed.

These objects and the various novel features ot the invention are hereinafter more fully described: and the preferred form of' construction of a printing machine embodying our invention is shown in the accompanying drawings in which- Fig. 1 is an elevation of a part of the machine showing our improved indicator arms and cords.

Fig. 2 is an end view ot our improved printing machine partly broken away showing the type holder and swinging head in position to make a type impression.

Fig. 3 is a similai- View with the head turned to position for the setting' of the type with the indicator in position over the bed or platen of the machine.

Serial No. 180,393.

Fig. 4 is a detail ot' a clutch device tor releasably holding the slides in position.

Fig. 5 is an elevation partly in section taken from the lett side of Fig. 2.

The machine consists ot' a bed or platen 1 at opposite ends ot' which are standards 2. Between the standards is pivotally mounted a liead 3 permitting the head to swing from printing position in Fig. 2 to non-printing position shown in Fig. 3. The liead 3 includes a way 4 for type and a springpressed member 6 is provided which engages against the type to hold the same when the parts are in the position shown in Fig. 2 as is fully described in our pending application Serial No. 149,335. This type way includes not only the part 4 but also a bar 7 extending along the back of the casting 4 providing therewith a way the walls of which are at a right angle one to the other. On this bar 7 are mounted the slides 8 and 9 which, as wili be understood from Figs. 1 and 2, have a base or body preferably of sheet metal that engages over the upper and lower edges of the bar 7 and slidable thereon. Each slide is provided with a finger 10 lying in the type space against the respective ends of the set line of type. On the back ot' each member 8 and 9 is a latch device 11 which consists of a stationary portion 12 and a member 13 pivoted on a rod 14 connected with the stationary member. On this rod is a coiled spring 15 which turns the member 13, when it is released. The forward end ot the member 13 extends through a slot in the member 9 to engagement with the bar 7 trictionally holding the member 9 in place but readily releasable by the operator grasping` the saine between the thumb and finger and sliding the member 9 to any desired position. Any approved means may be provided, however, to releasably hold the members 8 and 9 in place. On the back ot' the members 8 and 9. will be understood from F ig. l, an outwardly projecting rib or iiange 15 and 17 respectively to which are fastened standards 18 and 19 respectively which extend upwardly along the back of the machine.

In Fig. 1 shown a set line of type as it appears from the rear of the machine, with the parts 8 and 9 in position thereon. It will be understood from Figs. 1 and 2 that the fingers 10 engage the end type of the line. Such lingers are on the opposite side llt) of the member 7 in looking at Fig. 1 and the dotted lines in Fig. 1 show the position the bars 18 and 19 may assume when a shorter line of type is in the type way. lt is also to be ul'lderstood that these two members 8 and 9 and arms 18 and 19 attached thereto may be moved in any spaced relation to any position along the said bar 7 depending upon the position the impression is to be made on the sheet not here shown but to be understood as being supported upon the bed 1. Thus, it will be evident that the bars 18 and 19 are spaced a distance apart approximately equal to the length of the line of set type.

Each of the bars 18 and 19 has a pair of arms 20 and 21 pivotally supported thereon and the specific character of this pivotal member is not material. Preferably, however, the pivotal member is formed by a headed pin 22 having a washer 23 thereon and extending through an aperture in the end of the bar and on the opposite side provided with an eye 24. This is the construction at each of the joints and. on the parts being assembled, pivot pin is drawn sufficiently tight to hold the arms in any position to which they may be turned by hand. In addition to the eyes for each of the pivot pins of the arms 21 and 22 there are also provided eyes 25 and 26 on the fixed arms 18 and 19. Also to each end of the member 7 is secured a bar 27 which, as is shown in Fig. 2. extends to the rear of the member 7 and has an upturned end 28 in alignment longitudinally with the eyes 25 and 26 at the lower end of the upright fixed arms 18 and 19.

A pair of cords 29 and 30 have one end fixedly secured to one member 28 and the opposite ends secured to the other member 28 at opposite end of the bar 7. These two cords each extend upwardly through the respective eyes 25 and 26 and the cord 29 only extends through the eye for the arm 20 on each of the members 18 and 19 and the cord 30 extends through the upper eye on each of the members 18 and 19. These arms 2() and 21, of which there are a pair on each member 18 and 19 have apertures at their ends through which their respective cords 29 and 30 pass as will be understood from Fig. 1. These cords lie in parallel relation between the pairs of arms 2() and 21 and when the printing head is turned to the position shown in Fig. 3. the movable arms 20 and 21 lie close to the surface of the sheet to be printed which is supported on the base 1. The two cords extending between the two movable arms of the members 18 and 19 define the upper and lower line of type impression while the ends of the arms themselves serve to generally define the opposite ends of the impression of the line of type. This, as will be understood from the foregoing, results from the fact that the niembers 8 and 9 which carry the arms 18 and 19 respectively also carry the fingers 10 which engage the end type of the line and the movable arms 2t) and 21 are practically in alignment with these fingers which extend forwardly into the type space from the members 8 and 9 in about the same plane as the flanges 16 and 17 of the members 8 and 9 shown in Fig'. 1.

It is also to be noted that, by making the members 8 and 9 slidablc on the bar 7 defining one wall of the type way, they may be made to occupy any position on the said member 7 so that the type may be set in any desired position longitudinally of the way and with the arms defining that position. As shown by dotted lines in Fig. 3 it is evident that the movable arms 2O and 21 may be turned on their' pivots as previously described to greater or less distance apart so that the cords extending between the ends of the movable arms may be spaced to correspond to the width of the type from which the impression is to be made.

From the foregoing description it will be understood that the casting 4 with which the type holder is associated is reciprocatable in the head 3 in order to make a type impression when the holder has been brought to vertical position shown in Fig. 2. To secure this reciprocatable movement of the member 4. I provide a pair of eccentrics one of which is indicated at 40 in Fig. 5 as being attached to the shaft 41. An eccentric band 42 engages the eccentric which is housed in a portion 43 of the frame member. There are two such housings, the other of which is indicated at 44 and in which there is a similar eccentric and band to each of which an arm 45 is connected and pivoted at its lower end to the casting 4. The shaft 41 and like shaft for the eccentric in the housing 44 are respectively connected to levers 46 and 47, and these levers are connected b v the rod 48. The lever 46 includes a handheld 49 and, by turning the handle from the position shown in full lines in Fig. 5 to the position shown by dotted lines, the shafts for the eccentric are turned thus raising the casting 4 and the type holder from the impression position to a position permitting the head 3 to be turned on its pivot as indicated in Fig. 3 for the removal and the resetting of the type in the holder. After the return of the head to the position shown the lever 49 is turned to the position shown by full lines in Fig. 5 causing the type 5 to make an impression upon the paper supported by the bed. These operating levers and eceentrics are not shown in 2 and 3 butl are to be understood as riding in the slot indicated at 50 in the said figures.

It is evident from the foregoing descrip- 'tion that this device for indica-ting the space on'the sheet which the type impression will occupy functions particulariy with that type of printing machine in which the printing head is moved from printing to lion-printing position for the setting et the type and thus the operator in setting the type has clearly betere him the space on the sheet that thc type impression will anbsequently bemade and thus the labor ot the operator is facilitated.

It is also evident that the device is ot simple character and that the vai-ions objects of the invention are secured by the censtruction shown.

Having thus brieiy described our inveii tion, what We claim and desire to secure by Letters Patent ot the United States is-- 1. In a printing machine, a bed on which a. sheet to be printed may be positioned. a head pivotally supported thercover to swing on a horizontal axis, a type holder, carried by the head, said holder incluiling a way in which type may be set, a bar providing one side of the said way, a pair of slidable ineinbci's on the said bar, said members including tingers extending into the way for the type and engaging the respective opposite ends of a set line of type positioning` the same longitudinally or" the way, a fixed arm extending from each of the said members. a pair of movable arms pivotally supported on each of the said fixed arms, a pair oi: cords having the opposite ends thereoic tixedly attached at opposite ends of the bar on which the said members slide. eyed members on the fixed arms through which the cords pass, one of the said cords extending through the terminal portions ot one ot the movable arms of each fixed arm and the other of the cords passing through the ends of the other pair of movable arms, the con struction iiiroviding that when the head is turned to non-printing position the cords and the terminal portions ot the movabie arms are brought close to the sheet outlining the space that the type impression will occupy thereon.

2. In a` printing machine, a bed on which a sheet to be printed may be positioned. a head tliercover and movable from 'i printing to a non-printing position, a way for the type including a bar, a pair ot members slidable on the bar, fingers on the said niembers extending into the way for the type and engaging opposite ends ot a set line ot type. a pair of arms for each of the said members and mo vable therewith` the arms being pivotally supported and trictionaliy held from turning on their pivots permitting manual positioning thereot, a pair ot cords having the opposite ends tixedly sccured relative to the respective ends ot the bar, each of the arms having eyed terminal portions, one of the cords extending through the eyes of one of each pair of arms and the other cord extending through the eyes oi the other of said movable arms, the arrangement permitting movement of llnl members longitudinally of the bar with the cords freely running through the eyes of the arms, the said arms and cords extending therebetween being brought over the sheet to be printed by turning the head t0 non-printing position.

3. ln a printing machine, a bed, a typo holding head supported thereon and adapted to swing from printing position over the siieet to non-printing position, a type way, shoes mounted relative to the way and having iingers extending tliereinto to engage opposite ends ot a line of set type, the said way being adapted to receive type of various widths, a tixed arm extending from each oit the said slides, a pair oi' arms pivotally suppiirtcd by each of the fixed arms and reirasably heid from turning, the terminal portion ot the movable arms having eyes, a pair ot cords one of which passes through the eyes ot one et the said movable arms on cach tixed arm and the other of which passes through the eyes of the other of the movable arms ot each iixed arm and with the arm ends outlining a rectangular space over the sheet when the head is turned to non-printj position and indicating the position of the type impression will be made thereon, i 'l cords extending along the said arms to slidable members and thence parallel ves ot the said movable arms in the posiioning of the sliding members relative to he type way.

ln a printing machine having a type carrying head movabie from non-printing position to printing position, a bed and an indicating device for visibly indicating to an operator. while the head is in non-printing position. the space on which a type iinpression will be made, said indicating device comprising two pairs ot' pivotally supported arms corresponding iii spacing to the length ot the iine of type set while the head iii non-printing position, a pair of cords exiei'iding in parallel relation between the tcrininai ends of the pairs of arms, the said arms being pivotally supported and frictienaiiy heid trein movement permitting the vaine to be manually turned to space the cords a distance apart corresponding to the width et the set type, the arms and cords therebetween being brought to close association with the sheet to be printed by ruiming the head to non-printing position and indiating the space on the sheet on which the type in ,sion wilt` be made when the head is brougn to printing position.

An imprese-ion indirator tor printing machines having` an impression surface and n type holder member adapted lo swing.: herefrom to a non-printine position, conuprisingin combination, a pair of arms slidably mounted in said press and having 5 meanet adapted to engage the ends of the line vif type as set` und other means controlled hereby to indieute on the impression suriziee the extent of the impression in one direction, a pair of cords for indicating the extent of thel impression in the other direction, amd means carried by Said arms for uflljustably supporting said cords, said last mentioned means being' adjustable in planes perpendicular lo the length of the line of type.

In testimony whereof we eign this epeeiieation.
