SPECIFICATION forming part of Letters Patent No. 547,758, dated October 8, 1895.
Application filed October 16, 1893. Serial No. 488,235. (No model.)
To aZZ whom, it may cancer-n.-
Be it known that I, SEMER G. WVELLS, a citizen of the United States of America, residing at Des Moines, in the county of Polk and State of Iowa, have invented a Printing-Press, of which the following is a specifioation.
My object is, first, to rotate a flat bed carrying a type-form in such a manner that it will engageaplaten at each revolution as required to print an impression upon paper from the form; second, to carry and rotate two or moro flat beds carrying an equal number of typeforms simultaneously in such a manner that they will be successively engaged by the' platen at each revolution of each form; third, to combine an independent inking device with each flat bed in such a manner that each form on each bed may be inked with a color differing from the colors applied to the other forms, as required in chromatic printing, or each form inked independently with colors alike; fourth, to combine paper-feeding mechanism with the rotating bed-carrier and the platen in such a manner that paper from a roll will be advanced between the platen and each form as required to print an impression by means of each form without requiring any intermittent motions of the rotary bed-carrier; fifth, to combine paper-cutting mechanism with the rotary bed-carrier and the paperfeeding mechanism in such a manner that it can be adjusted to cut oifpaper from a continuous roll or from fiat paper after each impression of the form or forms carried on each flat bed, or after any number of impressions have been made by different forms on difierent beds during each revolution of the rotatiug bed-earlier; sixth, to combine paper-cutting disks with the paper-feeding mechanism in such a manner that the roll-paper can be divided longitudinally and trimmed to suit the sizes of forms carried on the fiat beds; Seventh, to combine a feed-board with the paper-feeding and paper-cutting mechanism in such a manner that flat cut paper can be substituted for roll-paper in the operation of my invention; eighth, to provide mechanism for controlling the Operations of the paper-feeding mechanism in such a manner that the paper is retained stationary relative to the platen as required to make impressions thereon successively from different forms on different beds on the rotary bed-carrier; ninth, to combine stop mechanism with the paper feeding and cutting mechanisms in such a manner that the motion of the paper can be arrested, so that different lengths can be advanced successively as required to suit forms of difierent sizes upon the different beds carried by the rotary bed-carrier.
My invention consists in the construction, arrangement, and combination of a rotatable bed-carrier, flat beds adapted to support forms of type in position as they are carried around in a circle, inking mechanisms, paper-cutting mechanism for cutting od different lengths from a roll or a flat sheet, mechanism for dividing paper longitudinally, stop mechanism for regulating the lengths of paper cut off from a roll or a. flat sheet, and driving mechanism with a supporting-frame, as hereinafter set forth, pointed out in my claims, and
illustrated in the accompanying drawings, in
which- Figure 1 is a right-hand elevation of my press, showing the form of the end portion of the frame, which has a circular openingin the center, vand the edge of the circular opening broken away at one point to disclose the relative position of the toothed cirpular end of the bed-carrier fitted in the circular opening of the frame. One of the arms formed integral with the frame to support the axis of the rotatiug bed-Carrier is also partly broken away. Part of the top portion of the frame, where the cutting mechanism is located, is also broken away to disclose disk-cutters for splitting and trimming paper. Fig. 2 is a-n outside elevation of a portion of the left end'of the frame having a central circular opening corresponding with the opening in the righthand elevation shown in Fig. 1. The end of the rotating bed-carrier shown within the circular opening has a concentric groove in its face, within which a pin is adjustably fastened to engage and operate the paper-cutting mechanism, also shown in this view. Fig. 3

Fig. 13 shows a cam-groove for moving an inkingrollerlongitudinally. Figltisaview through the line y y of Fig. 9, showing the cam-groove that moves the roller-bearer Iaterally as 'requiredto move the ink-roller longitudinally. Fig. 15 is a side view, and Fig. 16 an edge view, of the same roller-bearer. Fig. 17 is an enlarged sectional view showing a device for imparting intermittent motions to the inking mechanism. Fig. 18 shows the form of a spring used to retain the clntch mechanism shown in Fig. 17 in an inpperative position. Figs. 19, 20, 21, 22, and 23 are face views of sections of 'a transformable cam-Wheel for operating paper-feeding mechanism and advancingditferent lengths at different times. Fig. 24 is a back view, and Fig. 25 and edge view, of one of the sections of the transform-- able cam-wheel, showing the integral device for fastening the section to a base. Fig. 26 is a Sectional view of a portion of one of the ends of the rotary bed-oarrier having an annular groove to admit and retain the fastening devices integral with the transformabie cam-wheel sections. Fig. 27 is a diagram showing how a continuous sheet of paper may be transferred from one press to another and turned over when the two presses are in right-angled positions to each other. Fig. 28 is an enlarged 'Sectional view showing the connection between the drive-shaft and the rotating bed-Carrier. Fig. 29 is a sectional view of a feed-board connectedwith the frame in place of a roller for supporting paper. Fig. 30 is an enlarged detail view showing the arrangement of tapes and rollers for carrying the paper between the platen and type-forms on the beds. Fig. 31 is an enlarged sectional view of Fig. 9, showing two wheels connected on a hollow hub.
The letter A, Wherever shown in the various figures, designates an end piece of the main frame, and A2 are cross-pieces that connect the two mating end pieces A.
A3 are the arms formed on or fixed to the outside faces of the end pieces A to support bearings for the axis of the rotating bed-carrier in a concentric position with the circular openings in the central portions of the pieces A.
A4 are the circular end pieces of the rotating type-bed carrier fitted in the circular openings of the end pieces A. V
A5 is the annular groove in the outside face of one of the pieces A4,-as clearly shown in Figs. 1 and 26, to admit the fastening devices of the transformable cam-wheel A6. It is obvious that the piece A4 is thus made to serve as a base upon which to fix the cam-wheel A6 in such a manner that the sections thereof can be detachably and interchangeably fastened, as required to transform the cam-surface on its'periphery, by increasing and diminishing the lengths of spaces between the inclines that govern the operation of the paperfeeding mechanism, so that different lengths of paper can be advanced at different times to suit type-forms difiering in size.
Figs. 19 to 26, inclusive, illustrate the con- IOO struction and application of the interchangeable sections composing the transformable cam-wheel A6. It is obvious that the width and length and shapes at their outerends vary as required to produce a wheel that has a variable cam-surface on its periphery. All the sections excepting one,zNo. 25, are provided with a fixed stud adapted to enter and traverse the groove A5, as shown in Fig. 26, to be collectively keyed fast by means of a section that is provided With a bolt, ,as shown Fig. 25. In order to fasten all the sections securely, one of them is provided with a detachable bolt A7, that has a head adapted to be turned in the groove A5, and the section then placed upon the bolt and secured in its place by means of a nut, as shown in Fig. 25.
A8 is the axle of the rotating bed-carrier to which the endpieces A4 are fixed.
A9 is the driving-shaft shown in Figs. 4, 8, and 28.
One of theend pieces A4 has cpgs on its periphery and is engaged by a gear-wheel B on the drive-shaft A9, as required to be rotated thereby.
B2 is a fiat platen that has projections B3 on its ends adapted to slide in bearings B4, formed in the end piecesAon the frame, as shown in Fig. 5.
Eli is a gear-.wheel that meehes with the drive-wheel B and transmiteV motion to the zoV platen in its bearings B4 by means of cranks ll, formed in the shaft B7, to which the gearwheel B5 is fixed.
B8 are bridles projecting upward from the ends of the platen through which the crankpins ll'J are extended from the arms B6, as clearly shown in Fig. 7, in such a manner that a rectilincar reciprocating motion will be iinparted to the platen at each revolution of the .sli-att 137 as the gang of bedsV carried by the bed-carrier are successively brought in position to present type-forms against the platen, as shown in Fig. 5, and as required to print an impression upon paper between the typeferiu and the plaften. The type-form on the bed and the platen move in the same direction and at the same rate of speed at the instant the impression is made and during suf` ficient time before. and after the impression to allow the parts to clear and prevent slurring, the platen moving in astraight line and the type and bed in a circle, and it is therefore obvious that the impression is made when the centers of the moving platen and the moving type-bed are inline with the axis Aof the bed-carrier and the axis of the shaft B7 that operates the platen.
O is a device for throwing the paper-feeding mechanism in and out of gear at intervals by means of the transformable cam-wheel A5. It is of triangular form, as shown in Fig. 1, and supported in a hearing O2, fi'xed to the face of the frame-'piece A in such a manner that an antifriction-'roller at its bottom will rest upon the periphery of the wheel and rise and fall upon the variable cams.
Cais a duplex rackthat has a slding connection with'the top edge of the device O.
O4 is a bar thathas a vertically-sliding connectionuwith the end of rack CSi and a bridle C5 at its other end, through which is extended a crank-pin C6 from the face of a disk C7, fixed to the shaft B7. As the disk C7 is rotated the rack Ca will be reciprocated, andwhen it engages the pinion C8 motion Iwill thereby be imparted to the feed-roller C9, (shown in Fig.
- 5,) as required to actuate the paper-roller 01 contiguous thereto, between which two rollers paper is advanced to the type-forms on the beds as they are brought into position relative to the 'platen.
D is a roller located on the delivery side of the press and connected with the roller C9 by means of an endless tape D4, and D2 and Ds are guide-rollers that direct the tape.
D5 is a roller connected with the roller (11 by means of 'a tape D6, and D7 andB are directing-rollers that engage the tape D.
D represents a roll of paper and D1o (shown in Fig. 29) a feed-board. Paper advanced from the paper-roll or the said feed-board passes between Ahe rol-lers C9 and CH and the carrying tapes D4 and D6, and by means of said tapes the paper is carriedaad guided between the platen and type-form, where it receives an impression, and then onward to and between the rollers D' and D5.
F is a roller carryingcutting-disks, and F' is a mating roller, and as the paper is advanced from between the rollers D and D5 and between F and F' it is split -longitudinally into widths as desired.
F2 (shown in Fig. 2), is a belt connected with a pulley Faon the end of the shaft B7 and the roller F', as required to actuate the papersplitting rollers F and Fp'. v
F4 is a knife and F5 a knife-carrier fnd FG a shear-edge, and as the paper passes between the cutters F and F' and is split and trimmed the desired widths it is advanced past the shear-edge F6 and cut the desired lengths by the descent of the knife F4.
F7 is a lever pivoted to the frame-piece A and connected with the knife-carrier yF5 by means of a bent bar F8 or in any suitable way, so that the knife will be actuated by the vibration of the lever F'l, as required to cut off the length of paper desired to fall upon the receiving-table F9.
' H is a spring that in its normal position retains the knife F4 elevated.
H' is a groove in the face of the left-hand end piece A4, and H2 is a pin adjustably clamped fast in said-groove, as shown in Fig. 3, to engage the free end of the lever F7, as required to vibrate the said lever. It is obvious any number of pins may be thus attached to successively engage and vibrate the said lever as the bed-carrier is rotated, and as required to cut off dierent lengths of paper at different intervals.
113 is an inclined groove that extends in- Ward from the edge of the circular end piece A4 and intersects the groove H' in such` a manner that the heads of pins Hgcan be readily passed from the outside of the piece A4 into the groove l-I', and vice versa.
It is obvious from above description that as the gear-wheel B, which meshes with the end piece A4, having cogs on its periphery, is rotated the bed-carrieris rotated and the gang of beds carried thereby are successively brought in contact with the platen B2. It is also obvious that one or more beds may be carried by the bed-carrier,or when more than one is carried one or more of them may be carried empty while one or more carry typeforms. It is also obvious that the ratio of revolutions of the shaft B7 and the shaft A8 must be in the proportion of one to the total number of type-beds carried.
J are the flat beds for carrying type-forms, connected with the bed-carriers in such a manner that they will move in the same orbit and successively pass the platen B2, as required to make an impression upon the`paper as it passes the platen B2.
J' (shown in Fig. 5) is a pivot in the end of the bed J, connected with the bed-carrier A4.
J2 is a chase carried on the bed J as shown in Figs. 5 and 10, as required to retain the type-form Ja, as shown in Fig. 5.
with a fiange at its top, as shown in Figs. O, 10, and 17; Jii, a spring. (Shown iu Figs. 9, 17 and 115;.)
.17 and .'JS are integral pinions, and Ji' is a roller, all assembled on a shaft J, that is fixed to the type-bed J, as shown in Figs. l, 9, and 17.
The sprocket-wheels J* have lamber-faces K, and the hubs of the integral pinions J7and J have corresponding ratchet-faces K' to engage the ratchet-faces K of the sprocket-wheels J* and serve asaclutch by means of which motion imparted at intervals from the pinions .17 and .lE to the sprocket-Wheels J'l. The spring Jf' is placed on the hub of the pinions JT and JH, which extends through the plate J5 and rests against the face of the pinion .17, as shown in Fig. 17, in such a manner that it will hold said pinions disengaged from the sprocket-wheels Jet.
K2 is an endless chain extended over the sprocket-wheels J4, as shown in Figs. 4, 5, and lt).
K5 are composition inking-rollers journaled to the chains K2 in any suitable way, in such a manner that they will be supported and carried thereby, as required to traverse the typeforms on the beds J.
K4 and K5 are metal rollers journaled to the metal plates J5, to be carried therewlth.
K5 is a composition roller that engages the surface of the roller K5. It is journaled to brackets K7, as shown in Figs. yi, 9, and 10.
K8 is a cam-groove on the end ofthe roller K4, as shown in Fig. 13, and K is an arm placed on the said grooved journal, as shown in Fig. fl, in such a manner that the arm will move back and forth on said journal as the roller is rotated. This movement of the arm is caused by the pin K1, fixed in the arm to extend into the cam-groove, as clearly shown in Fig. l-lz. The shaft of the roller K5 is extended through the brackets K7 and through the movable arm K and secured thereto by means of collars, or in any suitable way, so that the motions of the arm will carry the roller back and forth endwise.
L are spring-actuated levers pivoted to the plate J5 by means of a rod L2 to carry a composition roller L5 'tt their` inner ends in such a manner that the roller Will, in its normal condition, be in engagement with the roller K4, as shown in Figs. lO, and 12.
L1 is a curved sheet-metal plate extended between the levei-s and hinged at its top edge to the rod IF.
1.5 are end pieces of the plate L* that adapt it to retain printeris ink.
1.5 is an eccentric roller journaled to the plates .15 in such a manner and position relative to the plate L4 that it will retain the free edge of the plate in contact with the roller K5, as shown in Fig. IO.
It is obvious that the flow of ink from the plate 1;* to the roller K5 can be readily regulated by simply turning the eccentrie roller.
LT is a gear-Wheel journaled on the end of tne roller K5, that extends through the-plate J5 and is located on the inside of said plate. If is a corresponding wheel on the outside of the plate J5 and fixed to the wheel L7, so that they will rotate jointly ou the shaft of the roller K5.
It is obvious that the bored hub of one of the wheels is extended through a bearing in plate J5 and the other wheel then fixed to the extended hub and the shaft of the roller K5 extended through the same hub to rotate therein.
L is a gear-wheel fixed to the roller K1 and meshes with and is actuated by the gear Li.
M is a pin-wheel fixed on the opposite end of the roller K5 from the gear-wheel L7.
M2 is a pin projecting from the face of the frame A, as shown in Fig. 5, and actuates the pin-wheel every time a bed J and the plates J5 are carried past the pin, as required to impart motion to the roller K5.
M3 (shown in Fig 5) is a cam fixed to the frame A in such a manner that it will engage and actuate the lever L .every time the lever is-brought in contact therewith, as required to depress the roller L3 to bring it in contact with the roller K5 to take ink therefrom and to be rotated thereby at the same time the roller K5 is being actuated by the pinwheel M, passing over the pin M.
N are concave racks fixed to the inside face of the frame A, as shown in Fig. 5 and indicated in Fig. 8.
K5 are convex racks fixed to the end piece A4 of the rotating bed-Carrier, as shown in Figs. 5 and 6. As the bed-carrier is rotated, the wheels .15 engage the concave racks N and the wheels JT the convex racks N2,successively, and are actuated by said racks, as required to operate the sprocket-wheels J4 to carry the inking-rollers K3 around the bed J, and at the same time to retain the bed in a parallel position relative to the platen D2.
Figs. 1 and 5 are drawn ou a scale of onefourth (l) inch to the inch. The disk CT is four and a half (4%) inches in diameter. pin (J6 is a half (fl) inch in diameter. The slot in the bridle C5 is four (4) inches in diameter. This gives the pin C6 a motion of three inches and a half (3%) in the bridle C5, both going and coming, which is equal to the motion given to the platen B2 (see Fig. 5) by the cran kpin BT, working on the arm B5, and the pin B9, working in the bridle B5, which are all of the same relative proportions to each other. A motion of three and a half (3%) inches is rimparted to the platen B2 and to the rack C3, both going and coming, making a total motion of seven (7) inches to each impression when all the beds are carrying forms. Therefore it is obvious that the extreme limit of paper that can be used on a form When there is a form ou each bed is seven (7) inches, or when there is a form on every alternate bed fourteen (14) inches of paper can be used, and when there are two forms on two successive beds one form can use seven (7) inches of paper and The.
Awheel A6 nearest its axis.
the other one twcnty-one (21) inches, or each form can be printed on the extreme ends of a sheet tWenty-eight (28) inches long, o'r by cutting in two can be made into 'two (2) jobs of fourteen (t4) inches length, or can be` printed in the middle of a job twenty-eight (28) inches long. \Vhen each alternate form is used each form can be given fourteen (t4) inches of paper, or a job can be printed twenty-eight inches long with each alternate page blank, or when forms are carried on all the beds, not duplicates of each other, a job may be printed twenty-eight (28) inches long, or of four (t) pages each seven (7) inches long. This shows the extreme length of paper that can be used in any job in the press herein described, and so the problem now arises how to get that length of that paper through the press at the proper speed so as not to slur ou the type or to tear the paper.
The toothed rack C3, attached to the slidingbar C4 and connected to the bridle C5, is driven by the crank-pin C6 at the same rate of speed as the platen B, as above described. The pinion Os on the shaft C9 in Fig. 1, has a diameter of one (l) inch -on its pitch-line. The roller on the shaft C9 and the roller Cm, Fig. 5, which co-operates with C9, are one inch in diameter and should be made scant enough so that when the tape is over them they will have the capacity of an inch-roller in moving paper. Each side of the toothed rackC3 is toothed for a distance ofI four (4) inches. VVhen the device O is in the position shown in'Fig. 1 the feed mechanism is inactive and the paper standing still. When the machine is started the bed-carrier rolls around until the antifriction-roller which carries the device O drops down to the periphery of the cam- If the different parts were so' assembled on their various shafts that the platen B2 and type-form were now in conjunclion and the rack C3 was in such a position that the pinion Oe was clear at one end of the rack C3, and assuming that we Want to print paper seven (7) inches to each form and a form on each type-bed, the cam-wheel A6 must be so constructed that the antifi'iction-roller which carries the device O will remain on the inner periphery until the disk CAT, carrying the pin C6, has made half a revolution and carried the rack C3 until the pinion reaches the opposite end of the rack. At this point the said antifriction-roller must be elevated to the periphery of the cam-wheel A8 most distant from the axis of said wheel, and then the press is conjunction with and at the time it is going away from the platen it is moving With the platen, so that there is no friction between the paper and the platen, and the platen and type-bed are moving together and all the parts working harmoniously without friction between the type and the paper or between the paper and the platen. Now, when it is desired to use less than seven 7) inches of paper, the cam-wheel A7 must be transformed so as to increase the length of time between the racks C3 going out of mesh on one side and in the mesh of the other side of the pinion CS. v time while the motion of the platen is being reversed, and may be increased down to a time when there is danger of slurring by the paper standing' still while the type-bed is near the platen.
It is obvious that at each revolution of the bed-carrier each bed will be carried around in the orbit of the oarrier without changing its parallel position relative to the platen, and that this is accomplished by means of the concave racks N, fixed to the statiouary frame of the press, and the smaller convex racks N2, fixed to the rotating carrier, and the gearwheels JB that travel in the concave racks N and the gear-wheels J 7 that travel on the smaller convex racks N2.
Referring to Fig. 8, which represents the pitch-lines and the orbits traveled by the various moving parts when the center of a bed is at the point marked a, the two gears J8 are in mesh with the racks N and the gear-wheels .17 are in mesh with the racks N2, the gear-wheels 'J7 on the right-hand side of the bed just going out of mesh and the gears .17 on the left-hand side just going into mesh with the rack N,
-and as the bed-carrier moves forwardV for a short distance the gears on the left-hand side of the bed are both in mesh, JB with rack N and J7 with rack NZ. When the left-hand gearsget to the point b, J8 runs out of mesh. From thepoint b to the point c, J8 is in mesh with rack N on the right-hand side of thebed and .17 is in mesh with rack N2 on the lefthand side ot' the bed. The said racks and pinions are so proportioned that the pinions at the opposite ends of the beds will have the same rate of rotation. From c back to the point a the movements described are simply repeated, the work done by the left-hand gears coming from ato c now being done by the right-hand gears going from c to a. In other words, the right and left hand gears act alternately relative to the racks N and N2 during each revolution ot' the bed-carrier. v
\Vhile thegroove P2 is concentric With the axes of the beds it is obvious that they simply act as a. clearance for the rollers which travel i-n the grooves P and P2; but. when said rollers are inithe groove P which is u`ot concentric with the axes of the beds the This holds the paper still for a longer IOO llO
grooveP guides said rollers and maintains the beds in their horizontal positions during the entire revolution of the beds except at the point where all the axes of the gears J7 JS, the journals J', and the axis of the bedcarrier A8 are all in line. At this time the gears J7 and J8 are tied together by the sprocket-chains and both running in the same direction and same speed, being driven by the racks N and N2, both sidesV of the bed being carried forward at the same time and same rate of speed. Neither side of the bed can lag behind or get ahead without breaking the sprocket-chains, and as this forward motion is equal to the forward motion given to the bed by the bed-carrier`it is obvious that the type-bed cannot tip, for the reason that it is supported at three points-first, the journals J', to which power is applied by the bed-Carrier; second,by the gear J8 on one side, and, third, by the gear .JT on the other side.
1) are grooves in the inside face ot' the frame-piece A corresponding with the segment of the orbit of the gears J7and JS; which is outside of the boundary line of the end piece A4 of the bed-carrier.
P2 are grooves in the surface of the inside face of the end piece A4 of. the bed-carrier, and together with the motion of said bedcarrier completes the orbit traveled by the gears J7and JS. The rollers .19 on the ends of the shafts J10 traverse the grooves P and P2 successively and serve as guides and bearings for the gears JT and JS. When a typebed J is at or near the points marked a and c in Fig. 8, the rollers J9,traveling in the grooves P and P2, are suficient guides and support for the type-bed to keep it in its parallel position relative to the platen B2, and the gears J7 and JS are disconnected with the sprocket-Wheel J4 by the action of the spring Jfi, and the sprocket-chain K2 and the rollers K3 are at rest, said rollers K3 being in contact with the metal roller K4 and being actuated thereby, as shown in Fgs. 5 and 10.
The gear-wheel L8 mesheswith and is actuated by the convex rack N2 and runs loosely upon the shaft of the roller K5, connecting with and driving the gear L7, which meshes with and actuates the gear L9 and drives the roller K4, thereby transmitting ink from the receptacle L4 to the form-rollers K3 while at rest, as heretofore described,` and as shown in Figs. 4, 9, and 10. After the inipression is o made by the type-forms carried upon the bed J coming in contact with the platen B2 and the type-bed is advanced by the rotary motion of the end piece A4 to the end of lugs R and R2 (Which are projections on the faces, the framepiece A, and the end piece A4 of the bed-earrier, one set being shown in Fig. 5 and a corresponding set is provided on the opposite side) the ratchet-faces of the gears J7andl that means the bed is held in its parallel position relative to the platen J. The gears" then run off the lugs R and R2 and the sprockets, chaius, and form-rollers come to rest until the type-bed is carried to the opposite side of the frame, where corresponding lugs are reached and the gears thereby again locked to the Chains, as before stated, and the form-rollers carried over the remaining half of their trip. After passing off these lugs, the rollers, having finished their trip, come to rest again, as before described, in contact with the inking-roller K4. The type-form vthen passes in conjunction with the platen, 4as heretofore described.
It is obvious that as each bed and type form thereon has acomplete set of rollers and inking apparatus each form may be inked with a different color of ink. It is also obvious that as many colors may be printed upon a sheet as there are type-beds carried by the rotary bed-Carrier by adjusting the transformable cam-wheel so that the paper will be held in a stationary position relative to the platen until the desired numberof colors have been successively printed thereon.
If it is desired to print from colors, put a different color in each one of the four fountains, adjust the transformable cam-wheel so that the distance the paper will be advanced by the periphery nearest the axis of the bedcarrier plus the distance it will be advanced by the periphery farthest from the axis is.
equal to the size of the job required. This fixes the matter so far as the first form is concerned,and the balance of-that quarter of the cam-wheel should be filled with the sections making the middle-sized periphery for holding the feeding mechanism inactive. The other three quarters of the cam-wheelmust now be const'ructed so that the paper will be drawn back after each iinpression far enough to be ready to be carried forward with the bed and platen in making the succeeding impression.
S (shown in Fig. 29) represents a device for holding cut paper on the feed-board.
