Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed June 8, 1908. Serial No. 437,302.

To all whom it may concern Be it known that I, WILLIAM A. Sons, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Printing-Press, of which the following is a specification.

. invention relates to improvements in printing presses and more particularly to that class employing an ink transferring medium between the type and cotiperating pressure element. A machine of this type is essentially useful for duplicating type written work and can be operated in business ofiices by inexperienced persons.

Among other advantages in. my invention are simple and inexpensive construction, adjustability of the parts, uniformity of impression by the type, and greater speed with reduced power and effectiveness in'operatlon than with machines of its class heretofore in use.

In the accompanying drawings forming part of this specification, Figure 1, is a plan view of my invention; Fig. 2, is a side vlew;

Fig. 3, is another side View taken in the opposite direction from that in which Fig. 2 is taken; Fig. 4, is a longitudinal section taken on the line X-X of Fig. 1; Fig. 5, is

a transverse section taken on the line YY of Fig. 1; Fig. 6, is a'detail side view illustrating the inking ribbon feed mechanism; Fig. 7, is a longitudinal section through the center of the impression roller; Fig. 8, is a longitudinal side view of the bed and the construction of what I have chosen to term the auxiliary guiding mechanism for the impression element; and Fig. 9, is a detail View partly-in section of one of the adjustable springs which assists in depressing the pressure or guide bars.

In the drawings A represents a substantially horizontal, rigid bed which is secured by brackets 2, to longitudinal sides 3 and 4 which form a stand. The surface of the bed is finished in a true plane for the typeform B to rest upon and has a pair of longitudinal ribs 5 which serve to reinforce the strength of the bed. At the forward and delivery ends of the machine are two

transverse shafts

6 and 7 upon which are secured at enial distances

apartsprocket wheels

8, 9, l and ll. pair of

parallel link bolts

12 and 13 travel at the same surface speed. Between these'belts l pon these sprocket wheels a sion roller is thereby caused to impinge against the type 15 in the type form during each cycle of the belts. The shaft 7 as shown is driven by a transverse shaft 16 and a drive pulley 17 thereon. The transverse shaft 16 is operatively connected withthe shaft 7 by means of intermediate worm.

gearing 18, said shaft-and worm gearing being suitably journaled in the casing 19 whichis secured on the side 3- of the stand by bolts 20. One end of theshaft 7 projects through the casing 19 so that a hand crank (not shown) may be attached to the machine for operating it when desired.

The impression roller C consists of a shell 25 having on its surface a thin jacket of resilient material such as vulcanized rubber and through which shell the shaft 14: extends longitudinallyfl The roller is freely journaled upon the shaft 14 by means of ball bearings 27 and 28 of ordinaryconstruct-ion which are located intermediate of the ends and within the casing of the roller, the bearing places being situated so that pressure upon'the surface of the roller is equally distributed and a uniform impression always made. I have found in practice this construction of roller particularly effective, for shoulder slight bend occur in the shaft or a narrow form of type be used the bearings cause the shell to run true while with prior art devices a slight inequality in the turning of the roller under such circumstances has resulted in producing a poor quality of work or in the printing press becoming wholly inoperative. In all other machines the line of travel of the impres-' sion roller is determined by its journal bearings while on this machine the perimeter of the roller travels over the type conforming to any inequalities thereof. The ends of the shaft 14 arefreely journaled in flanges 29 on a pair of the links of the belts. Immediately adjoining" each end of the roller, guide wheels 30 are rigidly-journaled upon the shaft 14. On one end of the shell 25 is a metal wear ring 31 and near each end of the jacket 26 is a circular space 32.

Above the roller (when on the upper lap of the belts) is pressure or guiding mecha- 52 in the ends of the spring bars 48.

nism which serves to press the impression roller downwardly toward the type in the form during each stroke of the impression roller. This pressure mechanism has apair of longitudinal and parallel pressure or guide

bars

35 and 36 below the lower edges of which the guide wheels 30 impinge and cause the roller to run over the surface of the type in the form on the bed of the machine. These pressure bars are carried by means of

transverse supports

37 and 38 which are rigidly secured upon brackets 39 on the sides of the stand by means of the bolts 40. The ends of the pressure bars rest upon inclined upwardly extending draw shoulders 41 which are formed on the upper surfaces of shift bars 42 when the pressure bars are in superior position. The corresponding ends of the shift bars at one side of the machine are notched at 43 and a pair of crank arms 44 have their power ends 45 working in said notches and their work ends rigidly secured upon a longitudinal shaft 46 which is journaled in two of the brackets 39. A handle 47 is secured to the shaft 46 and by swinging it backward and forward said shaft is turned and the shift bars 42 moved. lVhen the handle 47 is operated the shoulders 41 either raise the pressure bars into superior position or allow them to recede. Above'the shift bars 42 are a pair of spring bars 48 the ends of which rest across the ends of the pressure bars. These spring bars are secured to the transverse supports 37 and 38 by vertical screws 49 passing through said spring bars substantially midwaybetween their ends. The ends of the pressure bars are held in place by their shoulders 50, and pins 51 passing freely through shits T e ends of the spring bars 48 are held down under spring pressure below deep seated cups 53 in which are held helical expansion springs 54 through which vertical bolts-extend and pass through the ends of spring bars 48 into the transverse supports 37 and 38. The downward pressureexerted against the ends of the spring bars 48 and in consequence upon the ends of the pressure bars can be varied by adjusting the

vertical bolts

22 or 49. Below the end of each pressurebar is a stop 55 which is secured to the transverse supports 37 and 38 by means of screws 56 passing through slots 57. These stops have inclined shoulders 58 which limit the downward movement of the pressure bars by their ends resting thereon. By

loosening the screws 56, moving the stops and setting said screws, the inclined shoulders 58 can be changed in position to limit the downward movement of the pressure bars. All of the inclined shoulders on the stops 55 and shift bars 42 taper in the same general direction. As the belts travel around the bed, the wheels 30 impinge and run upon the lower edges of the pressure bars and cause the roller to press down toward the type in the form. The wheels 30 thus act as anti-friction devices and leave the impression roller to revolve upon its shaft freely. The wheels 30 on the roller do not come into contact with the longitudinal support bars 60 in the operation of the machine.

.The auxiliary guiding mechanism, which is primarily for preventing the impression roller from coming into contact witlrthe form on the bed and the inking ribbon during the entire movement of the impression roller when the pressure bars are in superior position and for revolving the roller forwardly at the same surface speed as that of the belts when the pressure bars are down, is provided with a pair of longitudinal track or guide bars 65 which are located below each end of the impression roller casing. Each of these track bars 65 is mounted upon a pair of vertical stud bolts 66 to the lower ends of which are secured lock nuts 67 which permit but limit vertical movement of said track bars. Helical springs around said vertical bolts are interposed between the track bars and the bed, having sufficient expansive strength to cause the roller to ride upon said track bars when the pressure bars are in superior position but are depressed when said pressure bars are down. The ends of the track bars are rounded off at 68 so that the roller is adapted to run freely on and off of the same. It is thus evident that the roller shell is re-. volved at. equal surface speed as the advance movement of the belt and is adapted there'- by to make an even impression in cooperation with the type and other parts when printing and does. not disturb the transfer inking medium or the material being printed upon.

Adjoining the auxiliary guiding mechanism are devices which are adapted to raise the roller in exact alinement to work in a horizontalplane upon the type without disturbing the latter when the pressure bars are down. These devices have a pair of longitudinal and parallel bars 70 from which stud bolts 71 depend through the bed. Helical expansion springs 73 surround the stud bolts 71 and impinge against the lower surface of the bed and lock nuts 72 on the lower ends of said bolts thus tending to draw the bars 70 toward the bed. For the purpose of raising and lowering eachbar 70 a pair of wedge blocks 74 is provided each block being placed with its inwardly tapering end sliding over the bed and impinging against one of the ridges 75, which are near the ends of the bars 70. The wedge blocks 74 are driven below the bar 70 and withdrawn by an adjusting screw in the form of a stud bolt 76 projecting from the bed and. provided with a threaded collar 77 running in a groove 7 8 in the lower surface of the block. Upon the upper edge of each bar 70 is a pair of skids 80 which are adapted to rest in the path of the'roller when the pressure bars are down. These skids are in the form of blocks having inclined shoulders 81 up and down which the impression roller is adapted to run and longitudinal slots 82 through which set screws 85 pass into the bar 70 and hold the skids longitudinally adjusted .thereon. The springs 73 on the stud bolts 71 referred to permit the skid bar 7 0 to be raised by the wedges 74. The skids raise the impression guides for causing the impression roller or element to cooperate with the type in the form; and the resiliently supported guide bars 65 serve to revolve the impression roller when said bars 35 and 36 are down HIIClftO' guide the impresion element out of cooperation with the type holding elementwhen the pressure bars are in superior position.. It will be noted that the lower edges of the pressure bars incline slightly down toward the inner portion of the machine at 83 so that the impression roller will be gradually guided with its surface in cooperative alinement with the type in the form.

. Running transversely across the bed and above the type form is a ribbon D of suitable transfer material. In practiced have used a ribbon or web of material similar to that employed in typewriting machines and a ribbon of thin paper or parchmenteeated withink thelatter producing better results for some classes of work than that which is possible for a transfer web to'produee. This machine being capable of minute ad ustment of the parts and smooth cooperation between the impression and the type holding 'elenients causes little Wear upon the ribbon and permits the use of thin inked parchment While with machines of the class of this invent-ion heretofore used itis necessary to employ a strong web. This machine being adapted to run the lines of type longitudinally with the travel of the impression ele ment also permits the'use of a transfer material made of paper or equivalent material.

The ribbon D passes horizontally across and" around longitudinal anti-friction roll-.

ers 90 above the bed ..thence downttlniough slots 91 in the bed, around anti-friction rollers 92 below the surface of the bed, to magawith the teeth of the ratchet wheel.

zine spools 93 and 94 upon which the ribbon is adapted to be wound. The

anti-friction rollers

90 and 92 are journaled in the bed.

The spools 93 and 94 are mounted upon

longitudinal shafts

95 and 96 which are journaled on magazine frames 97. These frames are formed on the sides 3 and 4 of the stand and are closed byhingeddoors 98 which are locked by spring snaps 99. The

shafts

95 and 96 are of the usual construction for supporting magazine spools of the characterdescribed and each is provided on one end with a beveled gear 100. Adjoining the ends of the

shafts

95 and 96 upon which said beveled gears are mounted is a transverse shaft 101 journaled and free to slide in the sides of the stand and upon which are mounted beveled pinio-ns 102. By

moving the shaft forward or backwardfirst one or the other of said beveled pinions is adapted to be thrown into mesh Withone of the beveled gears 100 thus causing one of the spools to Wind the ribbon and the other to pay it out or vice versa. By running the ribbon across the lines of ty'pe'instead of with the lines as i' other machines the edges of the ribbon do I ot curl. A handle 103 on the end of. the shaft 101 is for the purpose of operating the spools by hand to move the ribbon across the type holding element. The shaft 101 is turned a step forward each time the impression roller passes over the bed of the machine by said roller impinging against a dog E as ill11st1' %l. in- FigJG' of the drawings. The dog E consists of a bell crank lever pivoted at its angle by means of a pin 105 upon one of the track bars 60 near its overhanging end and having one arm 106 curved upwardly in the path of the Wear ring 31 on the impression roller. The other arm 107 of the bell crank lever is connected to a. rocker arm 108 by'means of a rod 109, said rocker arm-being rigidly secured .toaro'ck shaft 110 whichis pivoted "in the forward end of the track bars 60.

The rock shaft 110 carriers a lever 111 which is operatively connected to a ratchet dog carrier 112 by means of a reach rod 113. The ratchet dog carrier is freely mounted upon the shaft 101 adjoining a ratchet wheel 114 which is rigidly secured upon said shaft. A dog 115 is pivoted at 116 upon the carrier 112 and is adapted to engage the teeth of the ratchet wheel when the carrier is moved in one direction andto sweep over said teeth when the carrier is reversed. A spring connected by one end to an arm on the dog and by its other end to an arm on the carrier tends to hold the dog in engagement 118 secured to the bed engages the teeth 0% the ratchet wheel and prevents the shaft 101 reversing when the carrier moves its dog 115 back. It is thus evident that each time the impression roller moves over the bed and immediately after ithas cooperated with the type holding element it impinges against the lever arm 106 and depresses it as shown in Fig. 6 and thereby turns the shaft 101 forward and moves the transfer ribbon a step across thet-ype holding element thus presenting a fresh transfer surface to the type. A spring 119flsecured to the bed and to the arm 109 returns the parts of the ribbonfeeding mechanism described into normal position as shown in Fig. 4. By changing the lever to one of the pivot openings 129 the feed-may be varied to a greater or less extent as desired.

A system of paper guides is employed to receive the paper to be printed upon and by its use it is possible to register the paper both quickly and accurately. Cooperating with this system of paper guides is provided, means for automatically removing the paper, after it has been printed upon, from the machine. The paper guides consist of a longitudinal and vertical plate F which rests normally upon the ribbon above the type form on the bed and is secured to a bifurcated support 125 through which a transverse rod 126 supported on the side of one of the pressure bars 35 passes freely. A collar 127 through which the rod 126 also passes is secured between the bifurcations of the support 125 by means of the set screw 128. By loosening this set screw the longitudinal guide can'be set in any desired position transversely. Supported upon the rock shaft 110 are a pair of transverse guides 130 for the paper. These guides 130 can also be set in any desiredposition transversely by means of the set screws 131. The transverse guides 130 consist each of a, pair of upper and lower jaws 104 which are secured through longitudinal slots 132 to a longitudinal arm 133 by means of a screw 134. By loosening the screws in the transverse paper uides'thmjawmi said guides can be extent ed to adjust said giii'des longitudinally. The lower jaw of each trans verse guide carriesa stop 135 against which Each time the impression roller cooperates with the type holding element it impinges against the arm 106 of the ribbon feed mechanism and tilt-s the rock shaft 110 lifting the transverse paper guides intothe position indicated in Fig. 6 and the rearward edge of the sheet of paper which has been previously printed upon. At this point the mechanism for removing the paper from the machine cooperates with the guides by engaging the rearward edge of the sheet of paper which has been lifted by the guides and sliding the sheet of paper off the bed. Secured between the link belts by rigid connections with two of their links a transverse shaft 136 and upon which are 65 rigidly secured a pair of jaws 137. At

the delivery end of the machine is a carrier brush 138 which is mounted upon a transverse shaft 139.. This shaft is journaled in bearings 140 upon the sides 'of chine after it-has been printed upon. The

carrier brush operating at an accelerated speed causes the carrier mechanism to work efficiently and effectively to the end desired. Suitable guard plates 145 secured to the sides of the stand protectv the mechanism from dust and the operator from danger'by coming into contact with the working parts. As the belts travel the guide F sweeps over the impression roller and the carrier shaft 136'. The grooves 32 in the impression roller" permit the roller to operate out of contact with the ribbon guide rollers 90. v

In operation the sheets of paper to be printed upon are placed by hand one. at a time against the guides upon the form with their forward edges projecting between the jaws 104 of the transverse guides. As the belts are driven forward the impression roller and carrier upon the belts pass freely above the type holding element and out of contact with the paper to be printed upon. \Vhen the handle 47 is thrown forward and the pressure or guide bars 35 and-36 lowered the impression roller cooperates with the type holding element and causes the type to print upon the sheet of paper in the machine. As the impression roller advances from and after it has left the type holding element it'depresses the dog E and causes the ribbon feed mechanism to move the transfer material a stepforwar'd across the 110 type 'n element Mgr same action lifts the transverse guides into sltion shown 1n Fig. 6 thus raising the rearwar a transverse edge of the paper impinges.

edge of the sheet of paper above the face of the type form. The jaws 137 following the impression roller on the belts thereupon, engage the forward edge of the sheet of paper and push said sheet over the carrier plate 143 and onto the carrier brush 138, the latter ejecting the paper quickly from 12 the machine. Thecarriers carry the paper (substantially) without contact with the ribbon.
