To all whom it may concern:

Be it known that I, GEORGE J. NETH, a citizen of the United States, residing at Dayton, in the county of Montgomeryvand State 5 of Ohio, have invented certain new and useful Improvements in -.Paper-Feeding Devices for Autographic Registers, of which the following 1s a specification, reference being had therein to the accompanying draw- 'Ihis invention relates to paper feeding devices for autographic registers and the like and more particularly to that type of feed- 'a ing device in which p1n wheels enter rowsof 'l5 perforations in webs of paper to advance the same. -In forming the rows of perforations in the websof paper diiiculty is frequently experienced in maintaining the rows of per- -V forations atuniform distancesone from the other throughout the lengthof the web. Where there is a variation in the distance between the rows of perforations and the pin wheels are fixed relativel one to the other, the pins will engage the e ges of the perforations and tearthe paper, or if the variation is suiiiciently reat the willleave the perforations entire y, thus interrupting the feeding of the paper and/destroying the aline- .ment between the superimposed webs.

It is the object of my invention to provide means for driving or actuatin one or more sheets of paper positively an at the same time permit the paper to ad'ust the position of the driving means in or er to accommodate the elements of the driving means to the varying dimensions of the pa er due to atmospheric conditions and the l' e.

` It is a further object ofmy invention to provide such driving means which may be accommodatedl by the aperaceording to its lateral dimensions and) will hold the paper positively at a predetermined position while the sheets are bein worked upon or torn off.- -1 It isa still furterobject to provide such a holding means accommodating itself tothe dimensions of the paper to prevent'the paper slipping od yof the holding meansvor tearlng the paper and which will also revent movement of the paper and the therefor `in either direction.

. One object ofthe present invention is to provide a feeding device in which the dis# may be auto-v tance between the pi'n wheels riving means.

similar feeding device.

matically adjusted to accommodate the variatlons 1n thedistances between the rows of perforations in the' webs of paper.

A further object 4of the inventionv is to provide such a feeding devicev in which a pin wheel is mounted for free axial movement `so that it can follow the perforations in the web.

A further object of the invention is to provide such a device which will be very slmple 1n its construction and operation and which can be constructed and applied `to the machine at alow cost.

Another object of the invention is to pro-` vide a feeding mechanism with a detent pawl to engage one of the operating gears therefor to hold the same against reverse movement, said pawl being so constructed. and arranged that it will operatively engage ars of various diameters without change 1n the construction or mounting of the pawl, thereby avoiding the necessity of providing a special pawl for each diameter of gear, or of mounting the pawl on an adjustable suport so that it can be adjusted to accommof ate it to the gears of different diameters.

Other objects of the invention will appear as the device is described in detail.

In the accompanying drawings Fig.r 1 is a plan view of a portion of an autographic register, partly roken away toA show the feedin mechanism applied thereto; Fig. 2 is a si e elevation of a portion of such an autographic register;' Fig... 3 is a transverse section taken on the line-3 3 of Fig. l Fig.

y4. is a Ylongitudinal section taken on the line 4--4 of Fig. 1, looking in the direction of the arrows; Fig; 5 is a section taken on the line 5-5 of Fig. 1, looking in the direction of the arrows' and Fig. 6 1s a detail view of the adjusta lle guide bar.

In these drawin I havey illustrated one embodiment of my invention and have shown it as` applied to an authographic register of a known construction, but it will be understood that 'not only may the invention itself take yarious forms but that it may be ap lied to autographic registers of A various inds or to ot er mechanisms embodying a In.v that form of the invention here illustrated the autographic register comprises a. main frame, or casing,i 1 in which is l mounte mounted a feeding mechanism. comprising a shaft 2 journaled in the side walls of the main frame and having mounted thereon pinwheels 3 and 4 adapted to engage rows of perforations 5 formed in actuating elements 6 which are to be advanced by the feeding device. These actuating elements may be of paper or any desiredA material. The Shaft may be rotated in any suitable manner, but, as here shown, it has secured thereto a gear 6 which is connected by means of an idle gear 7 with a driving gear 8 mounted on a shaft 9 journaled in one of the side members of the main frame and having connected therewith a crank or operating handle 10.

The pin wheels 3 and 4 may be of any suitable construction. As here shown they comprise disks mounted on the shaft 2 and each having a circumferential series of pins projecting radially therefrom, the pins being tapered at their outer ends to facilitate their entrance into the perforations in the webs of paper. To enable the pin wheels to accommodate themselves to varying distances between the rows of perforations in the webs they are so mounted that the distance between them will lbe automatically adjusted according tothe variation in the distance between the rows of perforations. This mav be accomplished in various ways but in the construc-tion here shown I have mounted one of the pin wheels, the wheel 4, for movement toward and from the other pin wheel, this movement being imparted to the pin wheel by the contact of the pins with the edges of the perforations. Where the two pin wheels are mounted on a common shaft, as here shown, I prefer that one pin wheel should be rigidly secured to the shaft and that the other should he-mounted for free sliding, or floating, movement on the shaft, but should be connected thereto in such a manner as to prevent the relative rotation of the pin wheel and the shaft. In the (present instance the pin wheel 4 is on the shaft for free slidin movement and is held against rotation re atively theretoby laterally extending pins 11 which are mounted in bearings, or guideways, in a member, such as a cross bar 12, rlgidly secured to the shaft. This construction not only plrevents relative rotation of the shaft and t e pin wheel but prevents an tilting movement on the p'art of the pin W eel and retains the same in a plane at right angles to the axis of the shaft. It will be .apparent, therefore, that if the distance between the rows of perforations 5 andthe webs of paper vary the contact of the ins of the pin wheel 4 with the edges of t e perforations will impart lateral movement to the pin wheel on the driving shaft, thus maintaining the pin wheel always in line with the row of perforations. While, of course,

the second pin wheel may, if desired, be adjustably mounted this is not necessary as the web ofY paper will shift laterally Sulliciently t0 maintain the row of perforations in line with the pins of this second pin wheel, this lateral shifting of the web being permitted by the movement of the laterally movable pin wheel.

It is customary in pin wheel feeding de-l vices to provide the top plate of the machine which extends above the pin wheels, as shown at 13, with a. slotted guide bar, as shown at 14 in Figs. 3 and 5, these guide bars being so arranged that they will engage the uppermost web of paper and hold the same below the cuter ends of the uppermost pins of the pin wheel, thereby causing the pins to project through the openings and maintaining a firm operative connection between the pin wheels and the web. lWhere the pin wheels are fixed against axial movement the guide bars are ricidiy secured to, or formed integral with, the top plate 13, as shown. at 14. lWhen the pin wheel is mounted for axial adjustment it is preferable that the guide bar should also be adjustable. I have, therefore, shown the guide bar for the adjustable pin wheel as formed separately from the top plate, as shown at 15, and pivotally mounted thereon at a point removed a considerable distance from the pin Wheel so that the movement of the bar about its axis will not cause the slot to be placed at such an angle to the pin wheel as to interfere with its rotation. I also prefer to extend the bar some distance beyond its pivot, as shown at 16, so as to form a brace which will prevent the forward, or slotted, end of the bar from sagging or dropping away from the top plate. It will be apparent that inasmuch as the pins project into the slotv of the bar 15 that the axial movement of the pin wheel will also impart movement to the bar, thus maintaining the slotted portion thereof at all times in operative relation to the pin Wheel.-

A detent, or pawl, is'usually applied to one of the gears, preferably the gear S, of the feeding mechanism to prevent the reverse movement of the feeding mechanism. In different machines, or machines of different capacities, the diameter of the gear 8 will vary and to avoid the use of a dii'- ferent pawl for eac-h diameter of gear, it has `been customary to so mount the pawl on the main 'frame of the register that it can be adjusted to accommodate it to gears of different diameters. To accomplish this, however, requires a more or less complicated construction consisting of a number of parts and also requires that a'careful adjustment should be made in the assembling of the machine. In the present invention I have provided a single pawl which 1s so constructed and arranged that it can be mounted at th L c same oint on the side wall of any register and' will operatively engage the gear regardless of the diameter of the latter, thereby enabling a single part to be used where formerly several? arts were required and eliminating all a justment, which results in a material saving in manufacturing andV assembling costs, as well as preventing the possibility of the pawl being improperly adjusted or of the adjustable support slipping so as to render the pawl inoperative. As here shown, this pawl consists of an elongated body 17 pivotally mounted at 18 and having its outer end curved to extend about the gear and provided with a tooth or nose 19 to engage the teeth of the gear, the arrangement of the pawl being such that the tooth will engage one of the uppermost teeth in the gear. The intermediate portion of the pawl is increased in width, as shown at 20, to provide sufficient weight to ,hold the same in operative engagement with the gear, thereby eliminating the use of springs. It will be noted that the arrangement of the pawl is such that it moves substantially radially of the gear and that it will occupy an operative position to the gear regardless of the diameter of the latter.

While I lhave shown and described one embodiment of my invention I wish it to be understood'that I do not desire .to be limited .to the details thereof I as various modifications may occur to a person skilled .inthe art. y
