16 Claims.

ing. It is necessary, in this case, that the design transferred should exactly cover the surface of the roller so that the two ends of the design will 15 combine and not mismatch or leave a blank space therebetween. In accordance with this invention, provision is made for causing the roller to travel bodily a distance equal to the length of the design during one rotation of the roller.

20 Among the objects of this invention are the provisions of improved mechanism for controlling the roller on to which a design is to be transferred to travel in the direction of the length of the design a distance equal to the length of the design 25 as the roller is given one rotation.

Other objects of the invention consist in the provision of a rugged construction providing means for causing the roller to travel over the plate from which the design is to be transferred 30 in such a way that the axis of the roller will always remain parallel to a given line, so that its speed of travel across the design will always bear the desired relation to the peripheral velocity of the roller.

35 Other objects include means for adjusting the translatory speed of the roller with respect to its constant peripheral speed so that the relation of the speeds will be such as to cause the roller to travel over the design to be transferred as it 40 makes one complete rotation.

Other objects of the invention consists in improved means for conditioning the mechanism for transferring designs from fiat plates of different lengths on to different sized rollers.

45, Still another object of the invention consists in the improved means for adjusting the mechanism for causing the roller to travel the length of the design in exactly the time required for a rotation of the roller.

50 Another object of the invention consists in the use of an improved plate in connection with a transfer roller which is controlled so as to vary its translatory speed with its peripheral speed.

The frame of the machine preferably comprises The pairs of legs are preferably rigidly spaced by means of spacer bars it which may be secured thereto in any manner. The legs may also be provided with extensions 55 either integral therewith or secured thereto, to which are secured carriage rails to and H by any suitable means.

The upper surfaces of the rails IS and I! are provided with tracks upon which carriage supporting rollers travel. These tracks may be of the same shape and each one may include inclined or beveled side portions H! with which. co-

operate rollers l9 arranged in pairs at each end of the carriage member 29. These rollers support the carriage member for movement in a horizontal direction and hold this member properly aligned to travel in the direction of the carriage rails. The other carriage member 2|, at the left of Fig. 2, may be provided with pairs of rollers 22 which roll on the top face of the rail l6 as lateral movement of the carriage member 2| is prevented by the rollers l9 and track I! through a connecting plate 23 secured to the members 20 and, 2|, as indicated in Figs. 2 and 3.

Each of the rails I6 and I1 is preferably hollow or U-shaped, as shown in Fig. 3, and within which are secured racks 24 and 25 with which cooperate gears 25 and 21 carried by a shaft 28 supported on the cross member 23 in bearings 29 and 351. This construction is provided for the purpose of causing the carriage to travel in a straight line direction, as is well understood.

The main carriage 20, 2|, and 23 is preferably driven by a threaded rod 3| suitably supported on the stationary frame and rotatable in a nut 32 suitably supported on the main carriage. The rod may be rotated by a crank 33.

For the purpose of communicating rotational movement to the transfer roller 59, the shaft 28 carries a gear 35. The gear is splined to the shaft for movement axially on the shaft for gear changing purposes. The hub of this gear is mounted between collars 3G and 3'! on a casting 38 which is slidably and pivotally supported on the shaft 28, and by means of which the gear may be shifted on the shaft 28. The casting also carries an arm 39 constituting a bearing for idler gear 4|] which continuously meshes with the gear 35, and which may be moved to mesh with any one of the various gears 45 keyed to a shaft 42 supported by brackets 43 and 44 on the cross plate 23 connecting the carriage members 20 and 2|, and which together with the carriage members constitute the main carriage. For the purpose of facilitating shifting the idle gear into mesh with any of the gears 4|, the casting 38 is provided with a hollow cylindrical upwardly extending portion 45 for receiving a spring-pressed locking pin 46 which may be operated by means of a head 47, by means of which also the casting may be shifted after the locking pin 46 has been withdrawn from a cooperating hole in a bracket 48 suitably secured to the cross member 23 of the carriage. As shown in Fig. 2, the bracket 48 is provided with a series of holes for locking the casting 38 and gears 35 and 40 in any position of adjustment. This gear mechanism, comprising gears 35, 49, and 4|, is so designed that it will cause the transfer rollers of different sizes to normally travel at the same peripheral speed as the speed of the main carriage.

The shaft 42 through a universal extensible connection drives a shaft 55 journaled in the carriage member 2| at the same speed. This shaft carries a gear 51 meshing with a gear 58 on the transfer roller supporting shaft 59 which may be provided, for purposes later described, with a crank 60, as shown in Fig. 1. Upon movement of the main carriage, comprising the carriage members 20 and 2|, and the cross member 23, along the tracks l6 and H, the shaft 59 is rotated at a speed determined by the position of by the main carriage with the gear 40 in a given position. The gear may be shifted and meshed with another gear 4| to change the rotational and translatory speeds of the shaft 59 and transfer roller on constant speeds of the travel of the main carriage.

The shaft 59 is supported in suitable bearings carried by complementary carriage members 10 and H, such members being preferably constructed as shown in Figs. 8 and 9, and which may comprise pairs of roller bearings 5|, Fig. 4, carried by the carriage frame member, and another pair of roller bearings 62 carried by the member 63 which is pivoted to the carriage frame member and which may be locked in position by a locking nut 64 on a pivoted bolt which is of well known construction. By this means the shaft and roller may be readily removed.

The supplemental carriages l0 and T I, are provided with rollers 72 which are mounted on inclined studs and cooperate with convergent faces 13 and 14 which are inclined to the vertical, and which are formed on controlling slides 15 and 76 provided with outer convergent faces H and 18 which move over rollers 19 on the carriage members 20 and 2|. By moving the members i5 and I6 downwardly, as shown in Fig. 9, the member 10 is moved toward the left, and by raising the controlling members 15 and 16 the complementary carriages 76 and 1| are moved toward the right. By means of this mechanism the transfer roller may be moved to the left or right, as viewed in Fig. 9, by means of which the transfer roller may be caused to travel horizontally over the table either slower or faster than the travel of the main carriage comprising members 29, 2| and 23.

For the purpose of controlling the rate of travel of the roller, with respect to the main carriage, automatically during the operation of the carriage the slides 15 and 16 are provided with rollers 80 and 8| which operate in slots 82 and 83 in members 84 and 85 keyed to a shaft 86 for uniform movement of the members. These members may be rocked, as indicated in these figures, and for purposes of facilitating adjustment scale marks may be provided on the member 84 which cooperate with scale marks on a slotted bracket 81 secured to one of the legs ID of the frame member. The member 8'! is slotted to receive a locking bolt 88 carried by the member 84 for the purpose of locking the member 84 in adjusted position.

By adjusting the members 84 and 85, the slots 82 and 83 in said members may be orientated in such a position as to cause the slides 15 and 16 to either move upwardly or downwardly as the main carriage is moved from the left to the right in Fig. 9. If the adjustment is made to cause the slides 15 and '15 to move downwardly during the travel of the roller from the left to the right, Fig. 9, then the horizontal distance traveled by the roller is less than the distance traveled by the main carriage 29, 2 I, and 23. When the parts are adjusted so as to cause the slides 15 and 16 to move upwardl as the main carriage is moved from the left to the right, Fig. 9, then the horizontal distance traveled by the roller shaft is longer than the distance traveled by the main carriage.

The plate from which the design is transferred to the roller is indicated at 90. Any suitable means may be used for holding this plate in proper position on the table l2.

The roller supporting shaft 59 may be raised from the table by means of cams 9| and 92 which and 2 I.

bear on the roller carried by the controlling slide and the roller carried by the shaft 56, Fig. 3. These cams are secured to a shaft 93 mounted in bearings 94 and 95 in the carriage members The shaft may be operated by worm gear 96 driven by a worm 97 on a shaft 98 mounted in the carriage frame member 20 which may be operated by a handle 99 shown in Fig. 4.

The movement of the crank 69 and roller carrying shaft 59 may be limited to one complete rotation by means of a stop pin I00, Fig. 10, which is pivotally supported on angle pieces on the carriage member 2i in order that it may be thrown into and out of operative position. Cooperating with this pin is an arm IBI on the shaft 42, before referred to. The shaft 42 makes one rotation for each rotation of the roller supporting shaft 59. When it is desired to limit the rotation of the roller to one complete rotation, the

. crank is turned until the arm IOI engages the pin I00. The pin I00 is then swung to the side and the shaft 42 is rotated and before it compietes the rotation the pin I00 is swung back into operating position, after which the shaft is further rotated until the arm l0l engages the pin I00.

During the operation of the machine, the plate 90 from which the transfer is to be made is aligned and secured on the table I2 with the forward edge of the design on the plate approximately in line with-a mark on the gauge I02, Fig. 1, which is laterally adjustable in an opening in a member I03 which latter member is longitudinally adjustable in a member I04 which is carried by the supplemental carriage frame 10 and in which said member is also adjustable. Set screws are provided for locking the various members in adjusted position. The next step in the operation is to move the roller to the front end of the machine until the arm IllI engages the pin I00, after which the parts I02, I03, and I04 are adjusted as required to bring the mark on the member I02 over the front end of the design on the plate 90. The next step in the operation is to withdraw the stopping pin 00. The main carriage is then moved to rotate the transfer roller and carry the roller across the plate 90. The next step is to move the stop I00 back into operative position, and then to continue the rotation until the arm IcI is stopped by the pin E00. The mark on the member I 02 may either be directly above the rear edge of the design or in front thereof or to the rear thereof. 'If the mark on the member I02 is directly above the rear boundary line of the design then the machine is in proper'adjustment for transferring the design from the plate 90 to the roller 50.

If the mark on the member I02 is in front of the rear line of the design it shows that the design is longer than the circumference of the cylinder and that, therefore, the roller must be controlled to travel a greater distance across the table during a single rotation of the roller. This control is effected by rocking the levers 84 and 85 counterclockwise, as viewed in Figs. 8 and 9, toward the position indicated in Fig. 11. This is accomplished by unlocking the lock bolt 88, Fig. 9, and by rocking the lever 84 counterclockwise, and the amount by which this lever has to be rocked may be approximated fairly closely after many operations have been performed by the machine. The lever is then looked in position and another trial is made. If the mark on the member I02 at the second trial will be located to the rear line of the design on the plate 90 at the end of the rotation of the roller 50, it shows that the levers 84 and 85 were moved too far in a counterclockwise direction. In this instance, the levers will be adjusted clockwise, locked in position, and another trial made. These operations are continued until the line on the member I02 coincides with the rear line of the design at the end of rotation of the roller. During these operations the roller is held in raised position by the mechanism before referred to, so as to be out of contact with the plate 90. After the adjustment has been completed the roller is lowered into contact with the plate when the roller it as its extreme forward limited movement. The roller is then again given one rotation by means of the crank 60 which causes the design to be transferred toward the plate 90 to the roller 50 to completely cover the roller and to match the ends of the design and to meet without overlapping.

If desired, the rotation indication means shown in Fig. 12 may be substituted for the stop mechanism shown in Fig. 10. This indicator may comprise a relatively movable pointer and disk I05 and I06, provided with scale marks suitably referenced.

The plate 90 is preferably constructed as shown in Fig. 13 in which it is shown as comp-rising a metal backing such as zinc I01, a layer of rubber I00 firmly cemented to said back and an upper coating or thin film I09 of cellulose or other ink repellant material. The upper layer or film I09 is firmly secured or cemented at every point of its rear surface to the surface of the rubber layer I08. This film is made of substantially incompressible material but is made to yield readily so as not to interfere with the operation of the rubber layer. The construction provides a cushioned inextensible but readily yieldable design bearing surface. The pressure of the roller on the layer I09 does not spread the design, as in the case in which the design is carried by the surface of a rubber plate, and as the layer I09 is secured to the rubber there is substantially no horizontal shifting of the design with respect to the table as the roller is caused to travel horizontally either slower or faster than its peripheral speed.

If desired, the transfer roller 50 may be held against the plate 90 by springs, or the like, H0

stretched between the supplemental carriages l0 and II and brackets ill on the main carriage members 29 and 2I. These springs may be adjusted as indicated to any desired tension and as required by different sized rollers 50.

The crank handle 69 on the shaft 59 could be used as the operating means by omitting the main carriage operating means SI, 32, and 33. The crank is used in the organization disclosed for taking up the lost motion in the gear mechanism before the roller is moved across the table.
