I 1,e1"7,03z 'PATENT OFFICE.

OF DAYTON, OHIO.

Auroenarnrc nners'rna Application flled January 13, 1921. Serial No. 437,047.,

two pin Wheels are used there sometimes,

arises difliculty due to the improper spacing of the rows 'of alignment holes on the two'edges of the paper, or to the slight inaccuracy of the setting of the pin Wheels themselves, causing a tearing of the paper around the holes and a consequent misfeed. Where but a single pin wheel is employed, however, particularly where this pin wheel is located to one side of the machine, there is a likelihood of the paper at the start of the feed pulling sidewi'se and leaving the pins. Also abuse of the mechanism by the jerking at the feed handle, or holding back on the paper would be more likely to result in tearing out the holes where one set of pins are used than where there are more than one. I

It is accordingly the object of my invention to provide auxiliary means for feeding. the paper' at the start of the feed, so that a full free feed is given at the start independent of the pin wheel, and also means for holding lthe paper at a. oint between the storagerolls and the writing table, to prevent undue shifting of the webs on each other while being written upon.

These objects and other advantages of. use

not only in this particular type of machinev but in .autographic registers generally 'I' 40 accomplish by that certain construction and arrangement pf parts to be hereinafter .more specifically pointed out and claimed.

In the drawings, Figure 1 is a detail end elevation of the device.

Figure 2 is a detail side elevation thereof.

Figure' 3 is a side elevation of an autographic register embodying the features of my invention.

While I have shown a single pin wheel feed, as the only feed except the auxiliary feed used in the register, I do not wish to 'exclude from the invention a^use of two different kinds ofpin Wheels, one on one side of the machine and one onpthe other,

each acting, so far as the webs with which it is in engagement, as a single pin wheel feed. This Will be readil understood without additional views, an the usefulness of the invention for a feeding of different 'lengthed strips at one and the same'operaltion will be 'evident without further discussion. Thus without other modification of the structure, a pin wheel like the one shown, but with a desired number of pins left off, could readily be mounted on the free' end of the shaft, and the pressure roller I extended to take care of this..

Such 'a register on a difl'erent princi le is shown in my coending application 'Serial No. 309,353, file July 8, 1919, same having ripened into Patent. No. 1,394,447, dated October 18, 1921.

Reverting to the structure shown in the drawings, it will be noted that a register is provided having a casing 1 and a writing table 2, over which pass a plurality of webs of paper 3, drawn from storage .rolls 4 mounted within the casing.

At4 the delivery end of the machine is mounted the feed shaft 5, same being under control of a feed handle 6. The handle isy provided with a depresible stop 7, which engages and holds it in locked' position at 'the end of each complete revolution of the .feed shaft.

` The usual pressure roll 8 is provided, and

as usual will be resiliently pressed toward the feed shaft.

Mounted on the feed shaft are a pair of segments or the like 9, which are set so that the peripheries of both have just come in contact with the roll 8 when the feed` 'i handle is in locked`position During tearing-ofl, the segments thusi serve as an effective cIamp. V

There are two disks 10 on the ends of the feed shaft, one of them incorporated with the pin wheel, which said disks are vof less radius than thesevments 9, but greater than the lbody of the pin wheel so that they will permit the roll 8 to rest upon the segments during their movement beneath it and maintain the saidroll away from frictional engagement during the pin feed.

The feed pin wheel is illustrated at 12, having the pins 13. arranged in spacing to correspond with the interspaced registering holes in the paper (not shown).

The pressure roll 8 in the instance illustrated is mounted on arms 14, 14,- which are spring-pressed toward the feed shaft and have noses 14a at their pivot ends, which may be engaged by a latch 15, when desired. For. a spring pressed pressure roll see the patent of T. F. Schirmer No. 940,481, dated November 16, 1909.

As so constructed, the operation |is as follows: The user first brings the paper up over the writing tablefand thence between the pressure roll and that part of the table or other stripper, 15a which in accordance with ordinary practice will be employed, between the pressure roll and the feed devices. To lift up the pressure roll requires a raising of the arms that support it, until engaged by the latch described.

After adjusting the forms printed on the webs with relation to each other, they are set over the pins, which together with the segments will protrude through the stripper element, whereupon the pressure roll is lowered, and the feed may be begun.

The unlatching of the handle followed by revolution thereof, will first result in a full and positive feed of the various webs of paper, by the two segments pressing upward against the roll 8 together with the action of the pin wheel. Once the paper is started, the segments cease to form any contact and the feed pins carry on the feeding, maintaining alignment, and drawing the exactly proper length strips of paper over the writing table and issuing them from the machine.

Relieved from the overeoming of the resistance incident to starting the feed, I have found that a single pin wheel will readily take care of the alignment feed as well as two pin Wheels. p

As soon as the operator has completed one full operation of the feed handle, the segments will preferably be just starting in to feed frictionally against' the pressure roll, when the handle comes to its stop or latch. This friction will hold the paper during.

. tearing of and prevent dislodgment thereof from the pins at the delivery' end of the machine.

In order to avoid any dislodgment of the paper on the feed pins during the operation of writing on the webs, I desire to provide means for holding it at the enteringend of the writing table as well as the issuing end.

The clamp bar 16 is accordingly provided, having arms 17, 17, pivoted to the casing of the Vmachine at 18, said bar straddling the writing table at the entering end thereof. Another pair of levers 19, or a single lever 19, on one side of the machine-only, if desired, are pivoted at 20 to th'e casing and also connected at their ends to the arms 17. A pivot pin 20ab mounted in the end of one 'lever arm is retained in a slot 20b in the other arm thereby permitting the necessaryV motion for the combined lever action of the rev/,08a

arms. 21 on their ends, which ride on cams 22 positioned on the feed shaft, said cams having notches therein which register with the ro'llvers at the exact point wherein the feed handle is in locked position.

Springs 23 act to hold the clamp bar down against the paper on the writing table, and the roller or rollers in position against the cams 22. The notch in the cams is such that the moment the feed shaft is started up, the

rollers 21 will be lifted, and hence the clamp plication of parts is all that is necessary to provide for this. The use of an elevating device on one side only would serve to tip the clamp bar, instead of raising it.

Having thus described my invention, what I claim as new and desireV to secure by Letters Patent` is: I
