MANIFOLDING MACHINE.

.Application led September 19, 1927. Serial No. 220,359.

My invention relates to paper guiding and tensioning racks vfor use with certain types ofI manifolding machines in which the paper webs are drawn along by hand over the platen of the machine and then dropped over studs or pins at the end of the platen, said studs engaging in holes formed in the paper webs. In such machines the paper is usually printed into forms which are alike for any given operation, and the primary requisite of such machines is that the various blanks in the forms should be brought into correct alignment with each other where the paper is to be written upon. The paper is brought from a point of storage up and across the writing machine platen, or autographie writing support, as the case may be,

and carbon paper or other means is interleaved with the and transverse the said webs.

- The feature which is provided for `by my present mechanism results in bringing the paper webs to true alignment over the studs or pins which are hooked into the several forms on the platen by pulling back on the webs after they are hooked over the pins. Such a device is known as a tensioning`de vice, and there are several types on the market.

In illustrating my invention I have shown it as applied to a flat bed manifolding typewriter machine which I have selected as typical of the typewriting manifolders, but it will be just as applicable to any kind of a mechanism where there are pins located at the endof the platen, and a tensioning device is required to pull the Webs of paper transferring several webs back toward the storage, after they havebeen dropped over the pins.

I accomplish my objects by that certain construction and arrangement of parts of which I show and describe two forms typical of others which are possible, and the novelty of which will be set forth in the appended claims.

In the drawings Figure 1 is a side elevation of a manifolding typewriter machine.

Figure 2 is a perspective detail showing the mounting of theslat frame and the roller frame with relation to each other, in my first form of structure.

Figure 3 is a perspective view of the roller frame and roller assembly.

'Figure 4 is a perspective of the slat frame and slat assembly.

Figure 5 is a detail plan view partly in section showing the mounting of the slat frame on the roller frame.

Figure G is a detail side elevation showing the slat frame and rollerpfrai'iie of my second form in displaced relation.

Figure 7 is a like View showing said parts in working relation.

Figure 8 is a perspective of the slat frame of my second form of structure.

Figure 9 is a perspective of the roller frame of my second type of structure.

I have illustrated a frame 1 on which is mounted a typewriting machine 2 which moves to and fro laterally and also forward and back on the frame. The platen of the machine is located beneath the path of movement of the typewriting machine, and the studs or pins (not shown) are at the end of the machine away from the'paper storage. The paper la is shown as being stored in a large Vcompound roll E22L which contains a series of webs differentially wound so as to feed oft' in such a Way as to bring the printed forms thereon into alignment over the platen, and maintain sufiicient paper between the roll and the aligning pins to permit of preservation of the alignment.

The flat bed manifolding typewriter machine is provided withside bars to which one or the other of the frames forming part ofmy invention are attached. These bars are illustrated at 3 in Figure l, and the rack upon which the line spacing mechanism of the typewriter operates is secured to these side bars. y Referring to the rst of the two forms of device illustrated, I have shown a frame 4, which may be rectangular in shape, in which are rigidly mounted a series of bars 5. There will be one bar for each web of paper that is to be employed. The bars have fast thereon, or slidable thereon the slotted plates 6. These plates have their slots depending at a slant, and rollers 7, which act by gravity in the slots, are provlded with spindles 7 which lie within the slots.

The slat framefS is also rectangular to fit the roller frame, and is provided with a series of slanting slats 9 extending across them so arranged that thegravity rollers will rest on and roll up and down on the slats.

When the two frames are mounted together, aswill be described, the paper webs are brought up, one over each Slat, then down over the slat and back up over the roller which lies on the slat from whence it is fed across the platen of the machine.

When a section of all webs is pulled forward and set over the aligning pins, the gravity rollers will ride up during the advance, and as soon as the paper is released, Will ride down along the slats, thus pulling back on the paper slightly, and aligning it by means of the aligning pin engagement.

`My invention becomes of importance when it comes to the insertion `ot a new set of forms in the machine, in which case I rovide for some kind of a separation of the slat frame and the roller frame, which leaves the space clear for the operator to work, and still retains the'two frames so that when they are set back into operating. position, the paper will belcorrectly engaged.

Referring again to the first form of the device, I have provided a series of studs 10 in the roller frame, which are placed in bayonet slots l1 in the slat frame. The slat frame will b e just enough smaller than the roller frame that it will slide up into the roller frame from beneath, and the bayonet slots are such that when the studs 10 lie in the tops of the slots, the slat frame will have moved down Asuiiciently to clear the rollers in their lowermost position and permit easy threading through of paper webs. `When the slat frame is raised, and the studs are set in the notch in the lower endof the bayonet slots, then the slats are brought up into position of contact with the rollers.

It `would be practical to hinge the frames at one end, or latchk them in some kind of a way into two positions, all of which would to an extent accomplish my object.

In my second form, however, I have shown another arrangement in which the slat frame and the roller frame are spaced from each other in parallelism.

Thus I have shown in Figure 8 a slat frame 20 having slats 21, said slat frame being mounted fast in the side bars of the machine. The roller frame 22 is just alittle smaller than the slat frame, and is intended to be seated therein.

In the roller frame there are the fixed cross bars 23 on which are mounted the spaced slotted pieces 24, which in this case extend upwardly at a slant. The roller 25 rides in the slo The lower edge of the side frame pieces of the roller frame are provided with notches to engage over the slats in the slat frame, thus positioning the roller frame in correct relation to the slats. Thus I have shown the notches 26 along each side of the frame, said notches having the intermediate notch tongues 27.

When in operating relation the roller frame .is set into the slat frame so that the slats 11e in the upper ends of the notches.

lVhen it is desiredv to charge a new set of forms the roller frame is lifted, which can be done by sliding it forwardly of the machine, so that it rides up along` the notch walls. lVhcn the frame has passed to a position where the tongues 2T will engage over the tops of the slats the roller frame will rest in this position. The rollers will be thus all lifted away from the slats. and the operator will have space to charge in the new set of forms, whereupon the roller frame is lifted slightly and slid back into place for regular operation.

It will be understood that by referring to slats and a slatframe, that I intend to include any type of cross member such as bars,- large rolls, curved strips or the like. The term Slat is used for convenience as referring to a cross member in a structure of the type noted.

Having thus described typical structures embodying my invention, what I claim as new and desire to secure by Letters Patent, 1s:-

1. In a paper pull back device for manifolders, a roller frame having means thereon for retaining a series of gravity rollers so as to move in a slating plane, a slat frame having a series of slats across the same on Which said rollers ride, and means for mounting said two frames with relation to each other on the manifolder, so that they will have a position in regular operative relation to each other, and a second position with the frames spaced from each other to space the slats away from the rollers, thus permitting easy charging with paper.

2. In a paper pull back device for manifolders, a frame having a series of slats therein, another frame having a series of rollers therein arranged to co-operate with said slats in acting on manifolding paper, and means for mounting said two frames with relation to each other on the manifolder, so that they will have a position in which the rollers co-operate with the slats and another in which the rollers will be substantially widely spaced from the slats.

3. In a paper pull back device for manifolders, a frame having a series of slats therein, another frame having a series of rollers therein, and the rollers being so mounted and controlled as to have a path of movement along said slats, and means for so mounting said two frames with relation to each other on the manifoldcr, so that they will have a position in regular operative relation to each other, and a second position with the frames spaced from each other to space the slats away from the rollers, thus permitting easy charging with paper.
