18 Claims. This invention pertains to pin type feeding means for writing and imprinting machines, progressively engageable in longitudinally spaced 1 holes in continuous strips of record material for advancing it past a writing position, and more particularly to a traveling series of feeding pins which are automatically extended and retracted into andoutoifthe longitudinally spaced holes in the strip while the latter is being advanced through a relatively straight path of travel, as originallydisclosed and claimed in copending application Serial No. 16,008, filed April 12, 1935,

which resulted in' Patent No. 2,112,833 and of which the present application is a division, and to which cross reference is made.

The object of the invention is to improve the construction as well as the means and mode of operation of .pin type feeding devices for wrlt-' ing and imprinting machines, whereby they will not only be more eilicient in use but will be automatic in operation, uniform in action, having relatively few operating parts and unlikely to get out of repair.

A further object of the invention is to provide a pin type device having relatively loose engagement in longitudinally spaced holes in the record material, wherein the pins are advanced througha' relatively straight path of travel whil in" engagement with the record ma- :terial;

A further object of the invention is to provide a traveling carrier having extendible and retractable feeding p n to be progressively automatically projected into engagement with the material and withdrawn therefrom at predetermined points in't'heir path of travel.

A further object of the invention is to provide a pin type feeding means having the advantageous structural features and meritorious characteristics herein disclosed.

- 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 ins are shown in retracted inoperative relation.

, Fig.- 4 is'a longitudinal sectional view of the construction shown in Figs. 1, 2 and 3. I Fig. 5 illustrates a a portion of its path of travel disposed in a straight line substantially parallel to the path of travel of the record mafeeding. pins having terial into and out of the longitudinally spaced holes of which the pins are extendible and retractable, to which form of embodiment of the invention this divisional application is particularly directed.

Fig. 6 is a fragmentary view of a portion of record material having therein a special T-shaped shown in Fig. 6.

form of feed hole.

Fig. '7 is a detail perspective view of one of the feeding pin elements illustrated in Figs. 1, 2 and 3 for use with the T-shaped feed holes Fig. 8 is a sectional view similar to Figs. 2 and 3 illustrating the use of feeding pins devoid of the paper retaining heads or cross arms shown in preceding figures.

Fig.1 9 is a detail view of the straight type of feeding pins as shown in Fig. 8, to lie-employed in lieu of the headed t p pins shown'in-other figures, and which is equally applicable to the endless chain type feeding device shown in Fig. 5.

Like parts are indicated by similar characters of reference throughout the several views.

The purpose of the herein disclosed pin type" feeding device is duo-functional. It not only serves to uniformly advance superposed strips of record material toward the writing or imprinting position of a typewriter, tabulating. computing or billing machine, or other imprinting apparatus, but by progressive engagement of the feeding pins simultaneously in registering longitudinally spaced holes or apertures in the superposed strips of record material it assures and maintains registration of prescribed writing or impression receiving areas thereof as they pass the writing or imprinting position.

There are herein illustrated two forms of apparatus, mom of which the extendible and retractable feeding pins are mounted directly on a platen roll of a writing or imprinting apparatus and actuated into and out of feeding engagement with the record material by the rotation of such platen roll, which construction forms the subject matter of the parent application. In the other form of apparatus .to which the present divisional application pertains, the feeding pins are adiustably mounted on an end-.

lesstraveling .chain or belt, and are carried over.

. an elongated cam or track by which they are circuitous carrier for the Gil automatically projected through the holes in the recordmateriaLand at the limit of which they are automatically retracted therefrom.

The construction disclosedand claimed in the parent application briefly described, comprises a platen roll ill for use in a writing or imprinting machine having at each end thereof pin wheel units 20 which form continuations of the platen roll. Extending axially through the platen roll i0 and pin wheelunits 20 is a shaft I! on which 1 the platen roll is mounted for unison rotation spaced relation for oscillatory motion upon trunnions 26 are annular series of oscillatory elbow levers, comprising outer arms 28 which form feeding pins for engagement in longitudinally spaced holes in the record material to be fed, and inner arms 32 which control the extension and retraction of the pins 28. The strip engaging feeding pins 28 may be straight, and are preferably tapered to a blunt or rounded point as shown in Figs. 8 and 9, or may be provided with enlarged heads or cross arms 38, as illustrated in detail in Fig. 7 and as shown in Figs. 1 to 4.

Forthe present purposeeither form may be employed, but the form shown in Figs. 8 and 9 is preferred, since this form does not necessitate specially shaped feed holes as shown in Fig. 6

for reception of the headed style of pins, but is usable with stationery having relatively spaced round holes such as is now extensively used for manifolding purposes.

The inner unaligned arms 32 of the feeding pins 28 engage with a cam 34 stationarily supported within the platen on the tubular sleeve 24 as the platen rotates thereabout. During the greater portion of their circular path of travel about the cams, the feeding pins are held 'retracted, as shown at A in the several views, by individual retractile sp gs 56. When, however, the innerarms 32 of the feeding pins engage the high point of the cam 34, they are progressively oscillated about their pivotal connections 26 against the tension of the springs 56 into extended position as shown at B. The periphery of the pin wheel unit is provided with slots or "openings corresponding approximately to the ings in the peripheries of the pin wheel units comprise T-shaped slots, as shown in Fig. 1, thus permitting the cross heads to be swung from the in position A to the out position B, as clearly shown in Figs. 2 and 4. The straight pin s 28 illustrated in Fig. 9 necessitate only short straight slots extending peripherally of the pin feed the stationery in a substantially straight path of travel, either in its approach toward or its departure from the writing or imprinting position. To this end, pins of either the form shown in Fig. 7 or Fig. 9 may be mounted upon endless traveling chains or belts relative'to which the feeding pins are movable into engagement in holes in the record material and retracted. therefrom incident to their travel movement at l predetermined points in their paths or travel.

Referring to this form of pin type feeding means disclosed in Fig. 5, the same type pins shown in Figs. 1, 2, 3, 4 and 7 have been shown mounted on a continuous chain trained over relatively spaced sprockets 62 and B4. The feeding pins 29 are projected to the out position by their travel movement over a cam 66 underlying a portion of the chain '60 during which the pins are projected into engagement with the record material to feed the same in a straight path. The feedin pins 29 are pivotally mounted in the chain for oscillatory motion into and out of record material engaging relation. The engagement of their arms.32 with the cam 66 serves to oscillate the pins 29 to erect position and to so hold them while the pins traverse the length of the cam 66.

When the feeding pins pass beyondthe cam 60, springs 68 similar. to the springs 56 illustrated in Fig. 4 retract the pins out of engagement with the record material. Feeding pins of eitherjthe type shown in Fig. 7 or Fig. 9 may be employed,- in the circuitous chain belt type of feeding dvice shown in Fig. 5. In Fig. 9, a record material feeding arm 10 of straight construction tapering to a blunt or rounded end without the extensions 30 is shown. The arm 32 thereof by its engagement with either the cam 34 or the cam 66, according to the type of device, 'controlsthe extension and retraction of the feeding pins into and out of engagement in the longitudinally spaced holes in the record material. Such type of feeding pin may be used with record materialv having either round or oblong apertures. 4

The endless belt or chain pin type feeding device may be located parallel to the path of travel of the record material to engage therewith either in advance or beyond the imprinting position.

The feeding pins are progressively extended and retracted into and out of longitudinally spaced holes in the record strip while advancing it in a relatively straight path of travel. 3' From the above description it will be apparent that there is thus provided a device of the character describedpossessing the particular features of advantage before enumerated as desirable-but.

which obviously is susceptible of modification in 1ts form, proportions, detail construction and .51 arrangement of parts without departing fIOlIirjL-i means is employed, the rock sleeve 24 is so adjusted that the pins are projected at an inoperative position slightly rearwardly of the top of the platen roll, as shown in Fig. 3.

Such projection of the feeding pins in opera-"' tive or inoperative position at the will of the operator is shown and described in Letters Patthe principle involved or sacrificing any of itsi 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 'toi tion with the path of travel of the belt governing the extension and retraction of the pins.

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 scopeof the appended claims.
