cation for Letters Patent Serial No. 179,021, filed December 9, 1937, now matured into Letters Patent'No. 2,309,656.

The expansion and contraction of paper strips employed for record purposes, especially when the strips are of considerable width, as used in tabulating and computing machines, addressegraph and other imprinting apparatus, presents a troublesome problem. Prior to printing and punching, the material is kept in tightly wound stock rolls in a. comparatively dry condition as it comes from the mills. While in the stock rolls it pands to such degree that it will no longer fit the spaced pin feed devices for which it was originally intended, unless allowance has been made for such expansion. Inasmuch as the degree of expansion varies with changing atmospheric conditions and some grades of material are more susceptible than others to absorption of moisture and consequent expansion, it is diificult indeed to anticipate such dimensional variations. The present floating pin feed construction wherein the feeding pins may automatically change their plane of travel'to coincide with that of the apertures to be engaged, solves this problem and renders the feeding devices universally adaptable to varying conditions.

In the present feeding unit there are contemplated floating or laterally movable feeding pins or teeth which will automatically accommodate themselves to relative displacement or unalignment of successive feeding apertures in the rec- I 2 0rd strip, and which may be economically manufactured at low costs with minimum machine operations wherein the pins or teeth are individually and automatically adjustable laterally one relative to another.

The object of the invention is to improve the construction, as well as the means and mode of operation, of pin type strip feeding devices whereby they may not only be economically manufactured, but will be more efiicient in use, automatic in operation, uniform in action, of simple construction and unlikely to get out of repair.-

A further object of the invention is to provide apin type feeding device which will automatically adjust itself laterally to compensate for expanslon andv contraction of the record strips being fed .and inequalities in the relation of successive apertures therein engaged by the feeding pins or teeth, by automatically adjusting their position to the changed position of the feed holes.

A further object of the invention is to provide a pin type feeding unit wherein the feeding pins or teeth'are individually laterally adjustable one relative to another.

A further object of the invention is to provide a, pin type feeding device for use with apertured record material having the advantageous structural features, and meritorious characteristics herein mentioned.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Fig. 10 is a detail perspective view of one of the ing machines including typewriters, tabulating and billing machines, addressograph mechanisms, check writers and analogous apparatus wherein a strip of record material is progressively advanced past a writing position at which it receives a succession of longitudinally spaced inscriptions or recorded data. The present floating type of pin wheel or sprocket construction is also applicable to purposes other than feeding of continuous form stationery.

Referring to the autographic register illustrated in Figs. 1 and 2, i indicates the case or housing having in its top an opening 2, beneath which is the writing tablet 8, over which continuous' strip stationery 4 is advanced from a supply compartment within the housing into writing positionupon the tablet 3. The stationery strips 4, of which a packet is shown in Fig, 8, are provided with marginal longitudinally spaced apertures 5 for engagement of pin type feeding means, which in the present instance comprises the pin wheel unit forming the subject matter hereof.

In the particular type of autographic register illustrated, a pair of pin wheel feeding devices are rotatively mounted in the forward portion of the case or housing beneath the writing tablet, which is provided with slots 6 through which the feeding pins or teeth project into feeding engagement in the marginal apertures 5 of the strips 4.

'In lieu of the conventional round tapered feeding pins having a fixed plane of rotation in which they engage in round holes in the record material substantially larger than the pins, the

present feeding pins are flat and beveled or tapered. They are loosely mounted for to and fro lateral adjustment to automatically accommodate themselves to variations of position of the marginal apertures 5 due either to expansion or contraction of the material or to inequalities in the manufacture of the stationery.

It has heretofore been proposed to accomplish a somewhat analogous purpose by providing rigidly mounted feeding pins upon a pin wheel body or carrier, and mounting the body or carrier for to and fro axial movement. However, inasmuch as the movement must be eflected by the camming or lateral pressure of the margins of the apertures in the record strips against theen-' gaging pins, such complete pin wheel assembly is found too heavy and its inertia too great to be overcome by the edgewise pressure of the margin of the strip aperture. As a result, the

margin of the strip aperture may yield or bend, or indeed be torn. However, by rendering the feeding pins individually adjustable independently of their mount, the record strip is not required to overcome the inertiaof the entire Din wheel, but only one pin at a time. The pins oflering much less resistance than the entire assembly are readily adjusted by the aperture edge pressure thereon, without distortion of the strip.

Such pin wheel or sprocket units are ordinarily usedin pairs. If so, it is not necessary that both sprockets or pin wheels shall be of the free floating type. However, when two relatively spaced pin wheels or sprockets are simultaneously engageable in apertures in the opposite margins of the strips 4, as is the usual construction, one of the units is preferably of rigid form while the other is provided with teeth of adjustable or floating type as are herein illustrated.

The application of floating or laterally adiust- I able feeding pins to a pin type platen roll for a writing or imprinting machine is illustrated in Figs. 3, 4 and 5. The construction is of the type described and claimed in Patent No. 2,000,649, of May 7, 1935, wherein a series of radially disposed feeding'pins are progressively extended and retracted within circumferentially spaced holes in the platen roll by rotation of the latter. This is effected by providing within the platen roll 8 a temporarily stationary cam 9 about which the radially adjustable feeding pins ID are caused to travel as the roll rotates.

In the present construction, the feeding pins lll are flat and the circumferentially spaced holes l'l, within which the pins are mounted for reciprocation, are somewhat wider than the thickness of the pins to permit to and fro lateral motion within the limits of the holes. The pins l0 which may be stamped from sheet material are formed with a slotted wing l2 within the slot of which the lateral flange of the cam 8 engages. As the pins travel about the stationary cam 9 they are reciprocated into and out of the platen roll and are free for lateral adjustment additional to their reciprocatory motion. The slot in the wing 12 and cam flange engaging therein are of suflicient depth to retain operative interengageme'nt throughout the full range of lateral movement of the pins permitted by the size of the holes H.

The pins 'iiiare free for individual lateral movement each relative to the others.

A further variation of the individually adjustable pins is that illustrated in Figs. 6 and '7, wherein two discs l3 fixedly connected with each other have in their contiguous faces registering radial slots I4, which at their inner ends communicate with spherical sockets IS. The pins l8 flattened at their outer ends I! are formed with spherical heads i8 at their inner ends engageable in the sockets Him to and fro swinging or wobble movement within the limits of the registering slots i4. Each pin i6 is capable of a limited individual to and fro adjustment independently of the other pins. Such movement influenced by the relative positions of succeeding apertures in the strips enables automatic accommodation of the pin wheel to different locationsv of the apertures incldent to expansion or contraction and imperfections of manufacture of the stationery.

As shown in Figs. 8 and 9 the marginally punched stationery is provided with a succession of longitudinally spaced elongated apertures or slots 5. Such slots being relatively narrow may be located closely adjacent to the lateral margin of the strip where they will occupy materially less portion oi. the strip than the usual round holes and such narrow slot like apertures are much less conspicuous.

Whether the record material is expanded or contracted by varying weather conditions or the apertures are misplaced due to imperfections in manufacture, there will be no decided or abrupt oflset of succeeding apertures and points of the pins will readily find the succeeding apertures, and by lateral pressure upon the side of the aperture slot will shift laterally into a common plane with the aperture. The lateral adjustment of the feeding pins or teeth, whether affected individually or collectively, is due to the camming influence of the engaging pin or tooth on the side of the aperture. Due to such lateral pressure of the record material and feeding pin one against the other, the pin will yield laterally until it assumesa plane of travel coincident with the marginal apertures.

While for the reasons stated flat feeding pins cooperating with slotted apertures in the record material are quite desirable, the present invention is not limited thereto, but the floating pin construction herein described may embody conventional round tapered pins engageable ln'round longitudinally spaced holes in the record material. Since such round tapered pins and round holes are well known in this art, and their illustration in the present yielding or floating pin feed construction would necessitate substantial duplication of the present drawings, such specific illustration has been omitted, but the use of such floating round pins is deemed to be within the scope of the invention as expressed in the claims hereof.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangementof parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
