29 Claims.

The invention relates to printing machines for printing variable areas simultaneously.

The present invention differs from my former Patents 2,060,385 and 2,085,126 by devising a I mechanism which will automatically print two different designs'of. variable area simultaneously on the same article, whereas in the aforesaid patents, and in all other patents with which I am familiar, only a singie design is applied to the 10 article at one time. I accomplish this feature by providing a mechanism on the printing machine which imparts a difierential rate of movement to the printing members which carry different areas in the design to be printed.

u Selecting, but not limiting myself to a bottle, for example, it has been the custom to print a design on the body of the bottle, and then in a separate operation print a design on the neck of the bottle. The difliculty in printing on the body 20 and neck of the bottle results from the fact that the periphery of the body of the bottle rotates at a greater rate of speed than the periphery of the neck. The circumference of the body of the average beer bottle is approximately eight inches,

25 and the circumference of the neck is about four and one-half inches. This means that in order to simultaneously print on the body and neck of the bottle, the stencil or printing screen for the neck of the bottle should travel only four and 30 one-half inches while the screen or stencil for printing thebody of the bottle travels eight inches. In my present invention, I print on the larger and smaller area of the same article, in

a very efllcient, satisfactory and economical.

35 manner.

Another feature of the present invention is to devise a mechanism which performs all these functions automatically.

A further object of the invention is to print bands, marks, designs, objects, letters, or numerals in series or otherwise, or combinations of two or more of the foregoing elements in color on the bodies and reduced portions of bodies, such as bottles, which may be made of materials penetrable or impenetrable to the coloring materials.

With the foregoing and other objects in view, the invention consists of a novel combination, assembly, construction and arrangement of parts 0 as will be hereinafter more particularly described and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to without departing from the invention in the claims.

Fig. 12 is a diagrammatic view. showing the position of the chuck pins with relation to the cam on the work carrying member in theprinting, discharge and charge position. 4,0

Fig. 13 is a fragmentary perspective view of the chuck pin engaged in the cam.

Referring to the drawings, it will be seen that the parts of the machine are mounted on a stationary support A composed of a pair of parallel inclinedside beams l6, 11 secured to a pair of legs l8 near the middle, and another pair of legs 19 at the lower end of the beams. On each side of the support is a longitudinal brace '20 extending between the corresponding legs I8, IQ of each pair of legs. Depending from the ends of side beams are a pair of transversely spaced brackets 22 in the ends of which are journalled a shaft 23 towhich is fixed the pair or idle sprocket wheels 24. About these sprocket wheels I are trained one end of the pair of transversely spaced endless chains 25 which form the upper or discharge conveyor on which the articles are dropped, or deposited, from the work carrying member B to be later described in detail. The inner ends of the chains 25 are trained about driving sprockets 26 fixed on the drive shaft 21, which shaft turns the work carrying member B, and the drive shaft is Journalled in bearings 23, one bearing being anchored to each of the pair of supporting legs I 3.

The inner ends of a pair of outwardly extending arms 23 are secured to the legs l3, andlin the outer free ends of the arms are Journalled the charging conveyor drive shaft 30. On intermediate portions of shaft 30, are a pair of spaced sprocket wheels 3| about which are trained respectively, one of a pair of spaced endless chains 32 which form the charging conveyor. On the pairs of

conveyor chains

25 and 32 are V-shaped flexible prongs 33 fixed to the links. The members 33 on one chain of the pairs, align with the members 33 on the other chain to form a transverse pocket or saddle to receive the articles to be printed, which articles are shown in the drawings as bottles 34. Where articles other than bottles are to be printed, the prongs may be of various shapes to accommodate the shape of the article, and the space between the chains of each pair may be regulated accordingly by adjusting the respective sprocket wheels for the respective pairs of chains by means of the set screws 35, as is more clearly shown in Figure 6. It will be seen that the drive shaft 30 is drivenby a chain 36, one end of which is trained about the sprocket 31 on theend of the shaft, and the other end is trained about a sprocket 38 fixed on the outside of another sprocket 39. The sprocket 39 idles on a spindle 40 secured at its inner end to .the outside of the support A on one of the longitudinal braces .20. of the charging conveyor is trained about a pair of spaced sprockets 4-l fixed to shaft 42 that is journalled in the legs l9.

On the one side brace 20 is anchored the prime mover, such as an electric motor 43, the drive shaft 44 of which is connected to the transmission gears mounted in gear casing 45, and extending from the gear casing is the drive shaft 46. One

sprocket wheel 41 fixed to the drive shaft 46 on the inside, drives the sprocket 41 on the outer end of the crank shaft 48 by means of chain 49. Another sprocket wheel 50 on the outside, and fixed to the shaft 46, drives the work carrying member B by an endless chain trained about the Geneva gear C on the outer end of shaft 21. The chain 5| passes over the spring pressed sprocket 52, and about idler sprocket 39 from which sprocket 39, on the lower or charging conveyor receives its driving power as heretofore described.

The crank shaft 48 is journalled in the ends of the side beams |6--l'l, and in the centeris made with a bifurcated crank 53 between the arms of which the bearing collar 54 on the outer end of connecting rod 55 is journalled on the bolt 56 secured to the crank arms 53. The bolt 56 is slidable in slots in the arms 53 to adjust the throw of rod 55. On the terminal of crank shaft 48, outside of sprocket 41, is fixed a second crank arm 51 having a slot 53 which accommodates the adjustment of a bolt or crank pin 59 on which is mounted a ring bearing 60 on the connecting rod 6|. As will presently appear, the difference in throw in

cranks

53 and 51, with other ex- The other end of the chains 32 two printing members D and E, with which are associated respectively a scraping member F and G. As will presently appear, the printing members vibrate or oscillate in a normally rectilinear path and the scraping members sweep coloring material over the printing surface on both the outward and return stroke of each vibration or oscillation. The coloring material passes through the parts of the printing surface that are pervious to the coloring material and the coloring material passing through the pervious parts is transferred to the articles brought into contact or coincidence with the path of the oscillating printing surface by the work carrying member B. It will also be clear, as the description proceeds, that suitable mechanism is provided to move the printing members D and E toward and away from the normal vibratory or oscillatory path at the end of the stroke in one direction, and at the end of the return or backward stroke. The scraping members F and G are likewise moved toward andaway from the path of the printing members at the time the printing members are moved out of their normal path. The movement of the printing members and the scraping members out of their normalpath of oscillation prevents smearing the printing after it has been transferred to the articles.

The main printing member D is arranged to move over the body, and the auxiliary printing member E is arranged to move over the neck of the bottle 34, carried in the work carrying member B. The main printing member D includes a carriage made up of two rectangularframes disposed one above the other, the upper one of which is indicated at 62 and the lower one being indicated at'63. Both frames normally vibrate or oscillate simultaneously and continuously in a rectilinear path, but the upper frame that carries the main printing box to be presently described, moves toward and away from the normal path of oscillation at the end of the stroke in one direction, and also at the end of the return stroke in the opposite direction. The end rail 63a of lower frame 63 has a pair of bearing ears 64. Between the ears on the pin 65, secured in the ears, the sleeve bearing 66 on the inner end of connecting rod 55 is journalled. Crank shaft 48 imparts the vibratory or oscillatory movement to the main printing member D through the connecting rod 55 and the

frames

63 and 62.

The side rails 63b of the lower frame 63 have laterally projecting ribs 61 which slide in channels 68 on the side beams l6, I! of the support A and this provides for the oscillatory movement of main printing member D. The upper frame 62 of the carriage is supported on the lower frame 63 by means of four upright trip pins 69 located near' the comer of the frames. The heads of these pins 69 are fixed, as by riveting, to the side rails 62a of frame 62. The shanks of these pins 69 slide in openings in the side rails 63b. A trip rod H is slidable in a longitudinal bore 72, one in each side rail 63b, and the trip rod has a V-shaped cam notch 13 cut therein, one for each pin. The inner end of the pins 69 normally rest in the lowermost part, or trough of the cam notches 13.

The outer ends of the trip rods ll extend free of the ends of the lower frame and on each projecting end there is a spring 14, one end of which bears on the frame 63, while the other end of the spring bears against nuts 15 threaded on the terminals of the trip rods. Brackets I6, one at each end of each of the trip rods 1|, are bolted to the side beams I8, ll of support A, and in each bracket is an adjustable abutment, eachof which consists of aheaded bolt", the threaded shank of which extends through openings in the bracket. The heads on the bolts are in alignment with ends of trip rods II. The threaded shanks of bolts I! carry nuts I8 one on each side of the bracket; 'By tightening the nuts, the bolt is held fast, and when they are loose the bolt may be adjusted longitudinally of the bracket.

The springs I4 normally support the trip rod H in the position where the inner end of cam pins 69 rest in cam notches 13. When the trip rods 'II strike the abutments embodied in the bolts 11, at either end of the stroke of the printing members, the springs I4 at the end where the striking occurs, as shown in Fig. 1, are compressed as the trip rod moves. Whenthe trip rod moves, the cam pins 69 raise out of the cam notches 1 3, and the upper frame 62 movesat right angles to the normal path of oscillation. Since it will appear later that both printing members D and E move with the upper frame 62, then they are likewise moved into and out of their normal oscillatory paths by the same movement.

The rectangular printing box of the main printing member D is composed of side andend rails I9, 88 respectively, which form upstanding sides to the box for the purpose of confining the coloring material within the box. The printing box for the main printing member D is adjustable in three directions, that is, longitudinally and transversely of the machine, and also up and down. To accomplish this function, a pair of right angled arms at each end of the printing box have the legs 8I slotted at 82 to receive the shanks of bolts 83 which slide in the slots 84 in the end rails 62b of the upper frame 62. The upright legs 85 of the arms are slotted at 86 to receive the shank of bolts 81 anchored to the end rails 88. By loosening the wing nuts on the respective bolts 83 and 87, the main printing box may be adjusted, and by tightening the nuts, the boxes are secured in adjusted position on the upper frame 62.

The auxiliary printing member E includes a separate and distinct carriage member, shown particularly in Fig. 7, which imparts a differential oscillating movement to the auxiliary printing member with respect to the main printing member D. The carriage is composed of a pair of bearing blocks 88 slidable in a guide slot 89 in the one side beam I! of support A. Secured to and extending from the outer one of blocks 86 is a pin 98 connected to the inner end of connecting rod 6 I from which the auxiliary printing member E obtains its normal continuous and oscillating motion in a rectilinear path. From the inside one of the pair of blocks 88 projects a lug 9I, fixed thereto in any suitable manner. A second connecting rod 92 is connected at its outer end to this lug 9i by nut 93 threaded on the rod and bearing, one on each side, against the lug. The inner end-of connecting rod 92 is connected as at 94 to the confronting end of the bearing block 95 which slides in a guide channel 96 on the adjacent side rail 63b of the lower frame 63 of the carriage for the main printing member D. Connecting rod 92 extends through a slot 91 in end rail 63a of frame 63. It will thus be seen that the carriage for the .respective printing boxes.

panels H8 are the same in both the main and auxiliary printing member E may normally oscillate independently of, and at a differential rate of speed from the main printing member D so that a smaller printed area may be printed on the neck of a bottle at the sametime a larger area is being printed on the body of the bottle.

It is necessary to provide a structure capable of moving the auxiliary printing member E toward and away from its normal path of oscillation so that the printed matter will not smear, and also to provide for printing on both the outward and return stroke.v To do this, I mount a U-shaped member sidewise to slide on a pair of upright pins 98-that extend through the legs 99 of the member and across the outwardly opening channel I88 thereof. There are heads IN on the lower ends of the pins 98 which bear against the bottom face of one leg 99 and support the member. A portion of bearing block 95 extends into the channel I88 of the member, and on this portion the shanks of the pins 98 slide up and down. There are springs I82 under the portion of the bearing block 95 that extend into thechannel, encircling the pins 99, and bearing against the lower leg 99 so as to normally urge the U-shaped member downwardly. The upper end of pins 98 extend through a. guide slot I83 in a bar I84 to permit longitudinal movement of the pins. The ends of bar. I84 are fixed to the end rails 62b of the upper frame 62 and extend across the upper frame. There are nuts or bearing heads I85 threaded on the upper ends of the pins 98 which slide onthe upper face of the bar I84. Between the lower face of the bar I84, and the upper leg 99 of the U-shaped member, there are springs I86 embracing the pins 98, which hold the U-shaped member down on the projecting portion of bearing block 95, but'when the upper frame 82 is raised, as heretofore described, the bar I84; raises and moves the auxiliary printing member E with it.

, The printing box of the auxiliary printing member E is rectangular in shape and smaller than the printing box for the main printing member D. The auxiliaryprinting box has upstanding side and end rails I81, I88 respectively to confine the coloring material within the box.

The printing box for the auxiliary printing member E is'adjustable transversely and longitudinally, and is also adjustable up and down on angle brackets, one at each end rail I88. One leg I89 of each bracket is slotted at II8 to receive a shank of a bolt I I I anchored in the center of each end rail I88. Nuts on thebolts III secure the box to the leg I89. The upright leg II2 of the brackets is slotted at H3 to receive the shank of a bolt II4 having a head II5 on the inner end thereof slidable in a channel II6 on the web II'I of the U-shaped member. Wing nuts on bolts II4 hold the brackets to the U-shaped member.

The printing surface'for the printing boxes for the main printing member D and the auxiliary printing member E consists of a panel II8 one for each printing box, and this panel is secured to the lower edges of the side and end rails of the Except for size, the

auxiliary printing members D and E. The panels II8 may be made of a customary. metal stencil or a regulation cloth or silk screen. The panels form the surface to support a gob of coloring material which forms the design printed on the article 34 and they are impervious to the coloring material, except for the part II9 carrying the design, and this part II9 is pervious to the when it is brought into coincidence with the path of oscillation of the printing members by the workcarrying member B. The coloring material may be in powder, liquid, or plastic form customarily used in this character of printing.

In printing with my machine, the coloring material is swept back and forth over the panels iIB-by the scraping members, F indicating the scraping member for the main printing member D, and G indicating the scraping member for the auxiliary printing member E. As the scraping members sweep the coloring material back and fortli'over the panels,-a part of it passes through the pervious parts H9 and is transferred to the article, or bottle 34 on the work carrying member B.

Each of the scraping members F and G consists of a rigid metal or wooden shoe having a shank I20 provided with slots I2I. On the lower end of the shoes are flexible squeegee blades I22, preferably made of rubber, which are in wiping engagement with the panels I I8, and these blades scrape and sweep the gob of coloring material over the panels. The shoes of each scraping blade have their shanks I20 adjustably connected to a cross head I23, which extends across the machine. The cross head has a slot I24 extending through its thickness, and also extending across the major portion of its length, and bolts I25 in loose condition are slidable in these slots. The shanks of the bolts I25 passthrough the slots I2I in the shanks I20 of the shoes, and have wing nuts on their ends whereby the bolts may be tightened to hold the shoes in fixed relation to the cross head I23 for the scraping members F and G in any desired adjusted position. It will be seen that-the adjustment is'transversely of the machine, and also up and down.

It is necessary to provide mechanism to make the scraping members step from one side to the other of the gob of coloring material at the end of the outward stroke and also at the end of the inward or return stroke of the printing members so that printing may be done in both directions of the oscillating path like in my copending application Ser. No. 204,653, filed April 27, 1938. Toward this end, I provide sleeves I26 at each end of the cross head which slide up and down on the posts I21, there being one post the upper face, near each end of the side rails are pairs of cams I30, I30a respectively, th'e'pair at one end being staggered with respect to the "pair atthe other end. Adjacent the ends of the cross head are pairs oi fingers I3I, I3Ia mounted side by side in brackets I32 fastened to the cross head and these fingers rock in one direction, but are rigid to movement in the opposite direction. With the parts in the position shown in Fig. 1, fingers I3Ia have raised the cross head over cams I 30a, and will swing loosely in the bracket on the return stroke, at the end of which, fingers I3I are rigid when they contact cams I30, and swing freely on the return stroke. This movement causes the blades I22 to step from one side and come to rest on the other side of the gob of coloring material ready to sweep the coloring material in the opposite direction when the printing members D and E make the return stroke in their oscillatory path. v

The work carrying member 0 includes a. pair of disks I33 mounted concentrically on the shaft 21 in axial spaced relation, The disks turn simultaneously with the shaft 21. The one disk I33, at the left, as shown in Fig. 6 is adjustable to accommodate different lengths in bottles.

The hub- I330, has a channel that supports half of a key I33c which slides in a keyway I33d. Keyway I33d extends throughout three-quarters of the length of shaft 21 and a set screw I33b on the hub I33a bearing on the key I33c locks the said one disk in any desired adjusted position.

I have found it desirable to provide four article work holding stations, although any number may be used. With this in view, I provide four circular chucks I34 on one disk and four circular chucks I35 on the other disk corresponding in position to the chucks I34. Chucks I34 grip the base of the ,bottle 34, and chucks I35 grip the neck about the mouth thereof with the bottle axis disposed transversely across the machine. The periphery of the chucks I34 contact a flexible strip I36 to be presently described, to impart a rolling motion to the bottle or article held by the chucks, equal to the rate of movement of the printing member D only. That is, if the printing member D moves 12 inches in three seconds, the circumference of the body of the bottle 34 will move an equal distance during the same time. Chucks I34 are free to rotate on the pins I31 anchored in the adjacent disk I33. The chucks I34 have a cavity I38 in inner face to receive the bottom of the article such as a bottle 34, and the chucks I35 have a corresponding cavity to fit the mouth of the bottle. The face of the chucks may be shaped about the periphery of these cavities to correct any error in timing the pick-up of the bottle, and also to center the bottle.

Chucks I35 are capable of axial movement which allows them to grip and release the neck end'of the bottle 34 automatically. With this in mind, I fix one end of the pins I39 to the chucks. The shanks of the pins I39 slide and rotate in openings in the corresponding disk I33 and project on the outside where a fiat head I40 is formed. Between the disk I33 and the confronting face of the chucks I35 are coil springs I, one embracing each of the four pins for the four chucks. One end of the spring bears against the disk and the other end against the corresponding chuck. Chucks I35 are normally urged inwardly by the action of the spring, but when the object or article is gripped, the heads I40 project outwardly of the outer face of the corresponding disk.

On the inside of the support A is anchored a semi-circular cam race I42 of channel-shape in cross section which has the inclination of such a pitch that the pins I39 are pulled outwardly in the position X in Fig. 12 of the draw- .ings sufliciently to release the bottle 34, at which position the bottle is deposited on the cradle made by. prongs on the discharge conveyor made up of chains 25. The'head I40 remains ,in the extended position during the rotation for another quadrant, and at the position indicated at Y in Fig. 12 of the drawings, the head I40 slips free of the cam I42. At the point Y, a bottle 34 on-the charging conveyor made up of chains 32, is in substantial alignment with the corresponding chucks I34 and I35, and when the chuck I35 snaps inwardly under the tension of spring I4I, the bottle is gripped between the chucks. From the Y position in Fig. 12, the bottle is moved to the printing position Z shown in Fig. 12 of the drawings, and the relation of the bottle 34, the one printing member D, the corresponding scraping member F, and the work carrying member B in the position corresponding to the position Z, is shown In Fig. 11 of the drawings.

The work carrying member B is timed to rotate a quadrant of a revolution while the printing members D and E are raised by the trip rod H at each end of their oscillating path. This movement also occurs while the scraping members F and G are raised. Thus one bottle 94, is moved into the path of the oscillating printing surface, while the bottle previously printed is moved away from'the path and released on the discharge conveyor 25. This timed movement is controlled by the Geneva gear similar to that shown in my aforesaid co-pending-application.

This Geneva gear comprises an inner disk I55 keyed or otherwise fixed to shaft 21, and fixed to the hub H56 of the inner disk by means of bolts I51 is the outer disk I56. Between the two disks is a third disk I59 which is free to rotate on shaft 21. The chain 5I bears on the periphery of disk Q59 and the disk is rotated continuously by the chain.

Spaced equidistantly on the chain 5! in predetermined positions are a number of lugs or cams I60, which are designed to engage and swing a locking pawl I6I pivoted to leg I8 of support A at I62. The a bill or extension I63 that engages a notch I64 in the flange of the inner disk I55. A number of these notches I64 are provided and they are spaced equidistantly around the flange of disk I55 to correspond with the number and position of the chucks I34-I35. On the side of pawl I6I is fixed a pin on which the roller I65 is mounted. The pawl I6I is normally held seated in one of the notches I64 on disk I55 by a spring I66 anchored at I61 to the leg I8 at one end and to a projection I58 on the pawl at the other end. As the chain' 5I travels over the idler disk I69 the pawl is engaged in one notch I64, and the shaft 21 is locked against movement. I

Extending outwardly and fixed to the chain 5I are a number of pins I69 spaced equidistantly on the chains so as not to interfere with the movement of the chainover the other sprockets about which the chain travels. Formed on the periphe y of each of the inner and outer disks I55. I58 respectively, are pairs of aligned cleats I10 which are spaced equidistantly about the disks and each cleat is fashioned with a straight trailing face H011 and a round leading face I101). The cleats I10 correspond in number and position with the chucks l94l35.

The pins I69 engage the straight faces of the corresponding pair of cleats I10, at the same time the cam I60 raises the locking pawl I6I and the shaft 21 is turned about a quadrant of a revolution. This position is shown in Fig. 8 of the drawings. When pawl I6I drops free of the cam I60, it rides on the flange of inner disk I55 until it drops into the succeeding notch I64 whereupon ,of the cleats no with which free end of pawl I6I has the disks are locked and the shaft 21 together with work carrying member Bis made stationary while the printing members 1) and E immediately thereafter begin another stroke. At about the same time the pawl I6I locks the disks I55I58,

the pins I69 will have traveled a quadrant of a circle around the disks and are ready to drop free they have been engaged. To provide a certain amount of pressure to cause a whip or backlash in chain H to insure the pins I69 will jump free of their engaged cleats in case the pawl momentarily locks before the pins I69 are free, .an arrangement is made to provide tension against the roller 52.

An intermediate part of plunger I1I slides in a sleeve bearing I12, and the bearing has ears I13 fastened to leg I8 by bolts I14. The outer end of the plunger extends outwardly of the bearing and is threaded to receive a nut I15. On the inner end of the plunger is a bearing for the spindle I16 on which the sprocket wheel 52 rotates. Between the spindle bearing and the inner end of the bearing I12 is a spring I11 which applies tension on thesprocket wheel 52, which tension may be regulated by screwing the nut I in or out on the end of the plunger I1I.

It will be seen that I obtain compound movement in the work carrying member B. The one component is the intermittent rotary motion obtained by the Geneva gear C, which moves the articles into and away from printing position in the vibratory or oscillatory path of the printing members D and E. The other component is the rolling motion produced when the periphery of that chuck which is in printing position, engages the friction strip I36 causing the article to rotate at the same rate of speed as the main printing member-D.

The endless chain 5I is rotated continuously by the sprocket 50, and the chain passes over Geneva gear C, the tension sprocket 52, and the sprocket 39. When neither of the pins I69 nor the cam I60 are engaged, the chain 5I travels about the center disk I59 which idles on the shaft 21. While this phase of operation is occurring, the printing members D and E are performing the printing operation. At the same time, pawi I6I is engaged in one of the notches I64 in the'disk I55, and the disks I33 are stationary, while the one chuck I34 that is in printing position is being turned by engagement with the friction strip I36 at the same rate of speed at which the printing panel I I8 on the main printing frame D is wiping over the body of the bottle that is in printing position. At the same time the panel III! on the auxiliary printing member E is wiping over the neck of the same bottle, at a slower rate of speed than the panel II8 on the main printing member D, since there is a smaller area to print on the neck than there is on the body. The differential movement between the main and auxiliary printing members is produced by the difference in throw of the

cranks

53 and 51 respectively, and

printed; then the one pair of pins I69 on chain 5I engages the corresponding pair of cleats I10 15 on the disks I55 and I53, and the corresponding cam I60 lifts the pawl I6I, all of which results in simultaneous release of shaft 21 and the turning thereof for about a quarter of a revolution. The turning of the shaft 9. quarter turn moves one bottle away from the printing position and places the succeeding bottle in printing position while the printing members and scraping members are in the raised position.

During the time interval the pins I59 have traveled over a quadrant of the disks I55I58 I59 that form the Geneva gear C, the printing members shallhave been raised from their'printing position. At the moment the pins I59 free themselves from the cleats I19, the pawl I5I drops into the succeeding notch I84 in disk I55, and this action locks the work carrying member B with the one bottle I34 in printing position. At the same time, both printing members D and E and the scraping members F and G .drop or return from their raised positions to their normal positions and continue on the printing stroke in the opposite direction ready to go through the sequence of steps just described at the end of the stroke.

It is necessary to adjust strip I36 to accommodate the adjustment of the one chuck I33 transversely of the machine. The strip I36 is fixed to the lower edge of a wooden plate I44 and the plate is secured to a block I45 by a pair of spaced bolts I46, the heads of which are anchored in the block. The threaded ends of the bolts exand have knurled nuts I52 on the projecting ends. The bar I 5| has a clamping Jaw I53 which extends laterally of the bar and seats in a groove I54 in side rail 63b of the lower frame 53. The lower bar is likewise formed with a clamping jaw I49a which seats in a groove corresponding with groove I54. It will thus be seen that by loosening nuts I52 the bars I5I and I49 together with block I may be moved transversely of the machine in any desired position within the limits of the width of the clampingjaws I53 and Him.

Across one end of support A, there is secured to the end legs I9, a sheet metal skirt I99 as a protection to the operator from the throw of crank 53.
