BED-MOTION FOR CYLINDER PRINTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 549,262, dated November 5, 1895.
Application filed April l2, 1895. Serial No. 545,463. (No model.)
To @ZZ whom, it may concern.-
Be it known that I, EDWARD P. SHELDON, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented cert-ain new and useful Improvements in Bed-Motions for Cylinder Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention relates to means for imparting rectilinear reciprocations to the beds of cylinder printing-machines; and it consists in an improved means for performing the reversing operations of the type-bed, which consists of a crank-reciprocated head provided with a coupling-pin and means automatically operated to connect said pin with and disconnect it from the bed during each of the strokes of its reciprocation. By these means the bed may be moved at a high rate of speed throughout its major movements of reciprocation and be stopped and reversed ,at each end of its stroke by a crank movement which avoids jar to the machine and undue strain of the parts in arresting the momentum of the bed or in overcoming its inertia.
The invention includes various constructions and combinations of parts fully hereinafter described and explained, and finally set out in the claims.
A practical embodiment of this invention is shown in the accompanying drawings as applied in an ordinary single-cylinder printing-machine; but the invention is equally applicable to many classes of cylinder printingmachines and to other machines which include a reciprocating member, as is fully set forth in Patent No. 47 7 ,045.
In said drawings, Figure 1 is a side elevation of so much of a cylinder printing-ma-v chine as is necessary to illustrate this invention, the nearest side frame being removed to expose interior parts. Fig. 2 is a similar side elevation with some of the interior mechanisms removed in order to more completely expose others. Fig. 3 is an end elevation partly in section. Fig. 4L is a plan view of the central portion of said printing-machine, the upper section of the machine from a point just beneath the bed being removed. Fig. 5
vis a detail of the structure of the sliding coupling-pin. Fig. 6 is a sectional plan, and Fig. 7 an elevation, of the bed-moving mechanisms in vthe positions they have at the beginning of the reversing operation of the bed after its non-printing run. Figs. 8 and 9 are like illustrations showing said reversing operation half completed. Figs. 10 and 11 are similar illustrations showing said reversing 6o operations fully completed. Figs. 12 and 13 are similar illustrations showing the positions of the part-s at the beginning of the reversing operation of the bed after its printing run.
Figs. 14 and 15 are similar illustrations show- 6 5 ing said reversing operation half completed. Figs. 16 and 17 are similar illustrations showing said reversing operation fully completed.
The principal mechanism of the printingmachine is the reciprocating bed B, which 7o supports the form F and co-operates with an impression-cylinder C. This cylinder rotates in bearings provided in the side frames, being driven by a toothed wheel 50 through an intermediate 51, which gears with a wheel 59 75 on the driving-shaft 60. This driving-shaft 60 carries on its inner end a toothed wheel 52, of the same size as wheel 59, which meshes with the bed-driving pinion 53, said pinion 53 being doubly wide and arranged to slide side- 8o wise, so that it may be alternately geared with the rack 21 and the rack 22 to drive the bed B in opposite directions, its width being sufficient to enable it to be moved into gear with one or the other rack while constantly meshed with its driver 52. This pinion is mounted to turn freely upon a short shaft 23, projecting from a suitable interior frame, and is provided with a collar 24:, fast on one end,
which collar is embraced by pins projecting 9o from the bifurcated end of a rocking lever 25, fast to a horizontal rock-shaft, which is provided with a rock-arm 26, that receives its motion from a cam 27 on counter-shaft 2S,
which counter-shaft 28 isdriven by a wheel 95 wheel 11, of the same size as the pinion 52, 10o
and it is driven turn for turn from the latter and in the same direction by means of an intermediate 12 on a short shaft 13, which carries at its other end an intermediate 14, gearing directly with the wheel 11.
The crank 10 has a connecting-rod 15, at the outer end of which is carried a guiding-head or journal-bearing 32, in which is mounted a coupling-pin 16, capable of sliding therein,
which pin is provided at one end with a rightangular projection or toe 6, that travels longitudinally in a guideway 17, cut in the upper face of an oscillating frame 13. This frame 1S is mounted fast upon a rock-shaft, to which is attached a rock-arm 19, that enters the slot of a cam-wheel 20, which cam-wheel is mounted fast upon a shaft 29, that is driven at an appropriate speed by means of a pinion 30, meshed with a wheel 31 on the shaft 28. The guiding-head or bearing 32 of the connectingrod 15, in which the coupling-pin 16 slides, is carried in a box 33, that slides in a longitudinal way provided in a iixed frame 3i.
The bed B has depending from it a hanger 35, which has near its opposite extremity holes 36 37, into which the coupling-pin 16 is entered and remains to drive the bed during the reversing operation at each end of the movement of the bed, it then being withdrawn as the pinion 53 meshes with the appropriate rack to drive the bed during the major parts of its opposite strokes of reciprocation, as will more particularly be explained in connection with the operation of the parts.
The operation of the various mechanisms in causing the movement of the bed and its reversal at each end of its stroke will be understood by a consideration of Figs. 6 to 13, inclusive, in connection with the following description In Fig. 7 the mechanisms are shown in the positions which they have attained when the bed, having completed the major part of its outward or non-printing movement, (in the direction of the arrow,) driven by the pinion 53, While engaged with rack 22, requires to be reversed by being gradually slowed down from its highest speed and brought to a state of rest, then started in the opposite direction, be accelerated to its highest speed, and thereafter driven at that speed during the major part of its run in the printing direction, (that of the arrow,) as in Fig. 11, bythe pinion 53, engaged with the rack 21, and then be again reversed by being slowed down to a state of rest, as in Fig. 15, and started and accelerated in the contrary or non-printing direction, as in Fig. 17, when the pinion 53, automatically shifted laterally to perform this movement, is again engaged with the rack 22.
In Fig. 7 the bed B is shown as wholly within the control of the pinion 53, which pinion, engaged with the rack 22, has driven the bed throughout the major part of its non-printing run at the high surface speed of its driving-wheel 52 and is about to run out of the rack 22. At this time the coupling-pin 16 and the bed-hanger 35 will be traveling in the saine direction and at like surface speed,
and the coupling-pin 16 being exactly coincident with the hole 36 in said hanger the oscillating frame is moved by the cam 2() to slide said pin 16 longitudinally in the carrying-head 3, so as to protrude the same therefrom into engagement with the said hole 36, whereby the said crankdriven pin 16 becomes coupled with the hanger of the bed, which latter must consequently there after partake of the movements of said crank driven coupling-pin. As the crank-pin 16 moves from its upper position (shown in Fig. 7) to its central position, (shown in Fig. 9,) the crank 1() will, through the crankdriven pin 16, operate to gradually slow down the movement of the bed or, in` other words, gradually retard the rectilinear movement of the carrying-head 32 and with it that of the bed B until a state of rest is secured, as in Fig. 9, and while said crank moves from the position. shown in Fig. 9 to that shown in Fig. 11, at which time the bed will be traveling in the direction of the arrow in Fig. 11, the crank will gradually start and. accelerate the bed to the high speed which it has when driven by the pinion 53 or, in other words, start and accelerate the rectilinear movement of the carrying-head and with it that of the bed B until said high speed is reached, and during this half-rotation of the crank 10 the cam 27 will have acted to shift the pinion 53 from engagement with the rack 22, as in Fig. 6, into engagement with the rack 21, as in Fig. 10, and the arm 2O will have rocked the oscillating frame 18 so as to withdraw the pin 16 from the hole 36 in the hanger 35, as in Fig. 10, so that as the crank-pin 16 is closely approaching and passing its lowermost position and about simultaneously with ihe actual meshing of the pinion 53 with the rack 21 said pin 16 will have been uncoupled from the bed, so that the major part of the printing movement of said bed may be accomplished by the driving action of the pinion 53 and rack 21. Vhen the pinion 53 has reached the outer end of the rack 21 and is about to run out of the same, as in Fig. 13, the crank will be in its lowermost position, as in Fig. 13, at which time the guiding-head and the coupling-pin 16 will coincide with the hole 37 in the bed-hanger 35, said head, pinion, and bed then traveling at the same surface speed, thus enabling the coupling-pin to be moved by the oscillating frame 13 to be entered into said hole 37, thus coupling the bed to the crank. Now while the crank-pin is moving from its lowermost position (shown in Fig. 13) toits central position (shown in Fig. 15) the crank 10 will, through the crankdriven pin 16, operate to gradually slow down the movement of the bedthat is, progressively retard the rectilinear movement of t-he carrying -head 32 and with it that of bed the B until a state of rest is secured, as in Fig. 15and while said crank moves from the position shown in Fig. l5 to that shown in Fig. 17, at which time the bed will be IOO IIO
IIS
traveling in the direction of the arroW in Fig. 17, the crank Will gradually start and accelerate the bed to the high speed which it has When driven by the pinion 53 or, in other Words, start and accelerate the rectilinear movement of the carrying-head 32 and With it that of the bed B until said high speed is reached, and during this half-rotation of the crank 10 the cam 27 Will have acted to shift the pinion 53 from engagement With the rack 21, as in Fig. 14, into engagement With the rack 22, as in Fig. 16, and the cam 20 Will have rocked the oscillating frame 18 so as to Withdraw the pin 16 from the hole 37 in the hanger 35, as in Fig. 14, so that as the crankpin 16 is closely approaching and passing its highest position and about simultaneously with the actual meshing of the pinion 53 With the rack 22 said pin 16 Will have been uncoupled from the bed, so that the major part of the printing movement of said bed may be accomplished by the driving action of the pinion 53 and rack 22. When the pinion 53 has reached the outer end of the rack 22 and is about to run out of the same, as in Fig. 6, the first-described positions of the parts will have been reached.
1. The combination With a moving bed having a hanger provided at one end with an engaging hole, of a crank reciprocated head carrying a sliding bolt, and means for entering the bolt in said hole to control the reversing operation of the bed, substantially as described.
2. The combination with a reciprocating bed having a hanger provided with an engaging hole at each end thereof, of a crank reciprocated head carrying a sliding bolt, and means for entering the'bolt alternately in said holes in reversing the bed at the end of its opposite strokes of reciprocation, substantially as described.
3. The combination With a bed having a hanger provided With an engaging hole at one end thereof and With tWo racks, of a pinion for driving the same,7a crank reciprocated head carrying a sliding bolt, and means for coupling said bolt With the hanger as the pinion leaves one rack and nncoupling said bed and hanger as the pinion engages the other rack in the reversing operation of the bed, substantially as described.
4. The combination With a reciprocating bed having a hanger provided With an engaging hole at each end thereof and with two racks, of a pinion for driving the same, a crank reciprocated head carrying a sliding bolt, and means for coupling said bolt With the hanger as the pinion leaves one rack and nncoupling said bed and hanger as the pinion engages the other rack in the reversing operations of the bed, substantially as described. Y
5. The combination with a bed, as B, provided with ahanger having an engaging hole, as 36, and With a crank reciprocatedhead, as 32, guided in a horizontal Way and carrying a sliding bolt 16, of an oscillating frame 18 operating to reciprocate said bolt, to couple it With and uncouple it from said head in the bed reversing operations, substantially as described.
