JOHN Q. SHERMAN, F DAYTON, OHIO.

FLAT-BED MANIFOLDING MACHINE.

Application filed April 19, 1921.

To all whom it may concern:

Be it known that I, JOHN Q. SHERMAN, a citizen of the United States,and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements 1n Flat-Bed Manifolding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to manifolding machines particularly those employing a typewriter for making impressions on the sheets 1 of paper used, and those employing a fiat bed on which the writing is done.

It is the object of my invention to provide a pin wheel feed for paper, in such a device, andparticularly to drive said pin wheel device by a motor, said feed being coupled up with a device for withdrawing the webs of paper from a storage cabinet at the same time,

In connection with the withdrawing device, I provide as part of my invention, a movable feeding and aligning devicev for the webs of paper, which may be individual for each web, but in any case is so synchronized as to the amount fed that ample will be present at all times, for the main feed, and all webs aligned both longitudinally and transversely so that all the main feed needs to do is to correct mis-alignment arising between the withdrawing device and the said as main feed.

The movement of the feeding device is to permit of ready alignment of the various webs with relation to each other, and. then moving them in a body to a position sub stantially parallel with. the fiat bed, so that no webs have more strain on them than the others.

I acomplish my object and other advantages to be noted, by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a side elevation of a device made according to my invention.

Serial No. 462,677.

Figure 2 is a detail elevation, at right angles to Figure 1, showing the carbon paper feed, with its change speed mechanism.

Figure 3 is a detail side elevation of one of the carbon paper feed spindles.

In a co-pending application, Serial No. 37 0,839, filed in my name and that of Albert W. Metzner, there is described an electric operating device for driving a sprocket or pin Wheel feed for "manifolding register paper, having marginal holes therein. In the present application, the motor drive is the same as in that of the said application for patent, and the novelty residing in the use of said device herein resides only in its combination with other features not present in said earlier application.

The pin wheel feeding device for the main feed is substantially that of the patent to Schirmer, No. 940,481 to which reference is hereby made. i

The interleafing device, which is employed for the individualizing of the various webs of paper, and preventing fracture of the edges of the interleaved carbon paper is that i I of the Sherman and Metzner application Serial No. 391,499 and. reference is hereby made to said application for the details of this structure Referring to the machine in general, the writing bed or platen is indicated at 1, and frame at 2, and the storage cabinet at 3. The typewriter 4 moves over the platen in the usual manner, and the paper webs 5 are mounted in the storage cabinet in rolls 6, from which they may be withdrawn without excessive friction or hold back.

In a channel or roove 7 in the storage frame are set the series of bars 8, which carry the carbon paper protecting sheets or strips 9, each strip being of double structure so as to overlie the edges of the various webs of carbon paper 10, and protect them from fracture due to the movement of the webs of paper therebetween.

Mounted on shafts 11 on the upper portion of the storage cabinet 3, are a series of pin wheels 13, of like nature. Pivoted at 14 to the frame of the storage cabinet is a frame made up of side bars 12 suitably we braced together and in this frame is mounted a series of idler rollers 14;", one roller between each pair of pin wheels to guide and hold the paper on the pin wheels.

As shown, each one of the shafts 11 has a sprocket 15, and a chain 16 inter-connects all sprockets, and thus all shafts, and holds them in a fixed mutual relation.

The frame has two positions, one (Figure 1) elevated at an angle to the horizontal, where it is held by a bell crank latch 17 en gaging over a lu or catch 18 on the storage frame and the ot er lowered to a horizontal positionwith the lug 19 resting on the stop 20 on the storage frame.

The latches and stops may be duplicated or but a single set employed.

In loadin the machine, the frame is let down to its orizontal position and the webs of paper drawn from the rolls, and set over the pin in such a way that the proper point on each web has its apertures set over the proper pin of each piniwheel. This can be readily determined by observation, and as in all types of pin wheel feed machine, the holes will normally be arranged uniformly alon one or both margins of the webs.

A ter the webs are arranged over the balance of the machine the o rator raises the frame to its elevated positlon, so as to bring the idler rollers into proper position to guide and hold the respective webs of paper on their respective wheels. In driving the pin wheels, the revolution of any one of the set will impart revolution to the others through the sprockets and chain above noted.

I do not desire to be limited to the use of an individual pin wheel for each web, as experience has shown that several Websmay be fed by means of a single pin wheel. I will ordinarily employ two pin wheels for each shaft, but this also is optional, as a single pin wheel for each web or webs will suffice As noted above, the carbon paper protecting devic as more particularly described in another application, is arranged vertically and the webs pass from it to the platen of the machine.

At the issuing end of the platen, there is mounted a main feed shaft 30, on which are mounted one or more pin wheels 31, and suitable pressure roll lifting cams, for which see the Schirmer patent above referred to. The pressure roll, varying from the Schirmer patent, is shown at 32, and is mounted on a pair of arms 33, set fixedly on a shaft 34. This is under the influence of a spring 35, which acts to keep the roll in place on the cams above noted.

On this feed shaft 30 is also a sprocket 36, from which a .chain 37 runs to. an idler sprocket 38 on the side of the machine. This sprocket carries another sprocket 39, which is connected by a' chain 40 with the sprocket 41 on the first of the shafts in the frame over back from the main feed in loading the device the ro er apertures must be selected to provi e a ignment for all'copies at the mam feed, while'at the same time providing the same looseness for each web between the two feeding points.

1 have thus provided this storage unwinding feed to operate -as a unit with the main feed inorder to obtain a sufficient looseness of the paper webs between the two feeds in order to obviate the heavy pull or drag which would result if the main feed had to do all the work. In this way the main feed can function more properly in feeding the forms across the platen and in maintaining alignment at this point.

he machine shown has a motor operation, for which I have referred above to a pending application for the details. There is here shown a motor 42 of the type which will automatically switch itself off upon extra heavy load being applied to it. This motor has a starting button 43 and a gear 44, which meshes with another gear on the feed shaft. A suitable stop located on the main feed shaft comes in contact with a latch 45 at the end of each rotation of the shaft and this will also cause the motor to stop. When it is desired to start the feed, the latch isreleased and the starting button pressed.

Other details of the motor drivel have not described, as they are amply taken up in the said application.

The carbon paper feeding devices in this invention are of special type, so as to permit of an adjustable feed of paper, and also a feed which varies between the uppermost and lowermost of the strips of paper used. This carbon paper device, Figures 2 and 3, is on the opposite. side of the machine from that shown in Figure 1 and it will be understood that on the side shown, the carbon paper is mounted on a pair of ordinary rolls 50, and thence drawn up and across the platen, being there interleaved between the webs of paper to be written upon.

I prefer to employ, say two rolls of the paper, one having more strips than the other, and the one having the fewer strips set so as to have its strips come uppermost on the platen, and thus receive the greatest amount of wear. As will be noted, these sheets are renewed more rapidly than those below them.

0n the other side of the machine from that shown in Figure 1, the feed shaft is extended as at 51, and supplied at its outer end with a support in the side of the carbon paper trough 52. The carbon trough is also provided with a rigid plate 53, having a series of holes 54 therein.

I ngaging over the shaft extension 51, is a sleeve 56 which sleeve carries a fixed handle 57 thereon, said handle havinga pin at its end which slides under spring tension as at 58, to engage in one of the series of holes 54. The sleeve also carries a pinion 59 thereon and the handle carries a pinion 60 which meshes with the pinion 59 and is planetary'thereto. The pinion 59, while carried by the sleeve has a key disk 61 on its outer end for engaging in the key-way 62 in the shaft portion 51.

This construction enables the operator to shift the pinion 59 along the shaft, and hold it in a number of positions and keep the pinion 60 in mesh therewith at all positions.

he handle does not turn with the shaft, but the pinion 59 does and will drive the small pinion 60.

There are two carbon paper spindles, in

this instance as shown at 63 and 64, both of which will have cores 65 set thereover,

with the cores having starting clamps or rods 66 of-familiar construction and operation'.. 1 On the spindle mounting stud 63, set in the bracket 63 is a loose worm gear 67, and on the spindle mounting stud 64: also mounted in said bracket is a loose worm gear 68 of larger size than the gear 67. A shaft 67* mounted to revolve in the sides of the trough is shown as extended across both. of the worm gears and carries worms 69 and 70, which mesh with the two worms, and drives one faster than the other, as will be evident.

The worm gears are loose on the spindle mounting studs, and carry pins 71, which enter holes 72 in the ends of the cores on the spindles so that the cores and spindles may be withdrawn without disturbing the action of the worms.

The shaft 67 a has mounted fixedly thereon,

a set of gears 73 to form a cone gear, which will provide different speeds of drive by the positioning of the pinion mechanism on the feed shaft extension 51. A handle 74 may be used for revolving the shaft 67, for starting carbon paper-on the spindles, at which operation the shiftable gear device on the shaft portion 51 will be moved entirely out of meshing position with the gears at 73.

By this construction now described, it is evident, when the strips of carbon paper are brought over the platen, and secured to the spindle cores 65, that the operation of the feed willdraw a small portion of the carbon paper over the platen at each feeding operation, The lowermost sheets will be drawn more slowly than the uppermost ones, and the speed of both types may be varied.

One of the chief items of upkeep of large manifolding machines of this character is carbon paper, since heavy blows must be struck tomake six or more impressions, and this will deteriorate the carbon paper rapidly. Also the carbon paper will stick to the paper written upon and cause the feed to operate improperly, so that some small amount must be fed at each operation to break up adhesions.

Grades of carbon paper vary quite widely, and the operator would not require such a frequent renewal for good paper as for bad, and will always require a more. rapid renewal of upper sheets than lower sheets.

Mymechanism takes care of all of these features and makes the machine much more economical of carbon paper than one which makes no such provision.

I do not desire my failure to mention equivalent structures in the above description, to

be construed as a limitation of the claims that follow, as I have merely shown and described a structure which is preferred by me for most accurate operation and permanence of repair.
