In Shermans Patents, Numbers 2,000,649 and 2,000,651, issued May '7, 1935, a pin wheelfeeding the modifidevice has been shown wherein the pins enter the 25 record material along theradius of curvature of the material being fed so' as to prevent the tearing and mutilation thereof. In the embodiment shown herein the feeding pins in addition to having longitudinal movement along the radius 30v of curvature of the record material while advancing into and being withdrawn therefrom, also have movement laterally to accurately align the record material. The feeding pin, after having engaged andadvanced'the record material and 35 immediately prior to being withdrawn, may have a slight lateral movement rearwardly so as to permit the pin to be retractedfrom its aperture in the record, material without touching the edges bounding the aperture. r 40 Referring to Fig. 1 of the drawings the reference character Ill indicates a platen provided with a shaft l2 suitably iournaled in a writing machine carriage. As best seen in Fig. 4; a collar ll,

suitably attached to the shaft 12, carries the end frame or disc l6 supporting a cylindrical member II which is provided with a plurality of apertures 2| for receiving feeding pins 22. Member i8 is provided with a wall 24, carrying a plurality of studs I, two for each pin 22. A groove 28 extending spirally or in *askew relation in one side of the pin 22 receives the studs 28. The twostuds II for each pin 22 causes the pin to travel laterally a predetermined amount.

For the purpose of advancing and retracting 70 I portion 58, in that this portion is seated in the time the pins 22, an oval shaped cam 2| is provided The pins are held in contact with cams Q2 and ,with a flange 32 seated ina notch 88 found in each pin 22, the notch being oppositely disposed on each ,pin 22 with respect to the groove 28. Thus, it will be-se'en that as the platen is rotated the pins 22 will travel inan oval path so that the pins project beyond the platen during a portion of the revolution and are wholly contained within the platen during the remainder of the revolution. As the pins are advanced outwardly by the. cam flange 32, the pins are givena slight advance impulse in a forward direction due'to the studs 28 being disposed in the spirally arranged slot 28. This slight advance impulse in a forward direction causes the pinsto engage the forward edge of the apertures in the superposed sheets of record material as the pins move toward their full projected position, thus accurately aligning the sheets of record material. As thepins are withdrawn out ofengagement with the record material, or retracted, the studs 28 cause the pins to move laterally rearwardly as they move downwardly longitudinally, thereby moving away from the forward edges of the apertures in the superposed sheets of record material as the pins are retracted.

Referring to Fig. 4, the cam "is mounted upon the tubularsleeve lll'whichmay be oscillated from the position shown in Fig. 2 to the position shown in Fig. 3, so as to throw the pins from operative to inoperative position, in whichevent the record material may be fed past writing position by the friction feeding rolls 2 and 44 found on the conventional typewriters. The sleeve is freely rotatable upon the shaft l2 and independently of the platen l and may be locked in position by a suitable mechanism, one such fully shown and described in Sherman's Patent No. 2,000,649. j

In the modification disclosed in Figs. 7 t0.13 inelusive, the shaft l2 has fixedly attached thereto the collar Hi, rigidly supporting the disc I8, driving the cylindrical member 58, which forms a platen and is provided with a plurality of apertures 52.

The apertures are preferably oblong so as to permit a slight circumferential movement of the feeding pins 54 mounted in the apertures, which will be more fully described later..

By referring to Fig. 13, the feeding pin 84 cartion 58- parallel toshank 80, extending longitudinally to the platen and parallel to the shaft i2. The portion 58 rides upon a cam 82 having a tubular sleeve 84 fixedly attached to the tubular sleeve 66 mounted upon the shaft 12. Cam 8! governs the relative position of the pin 84 with respect to the periphery of the platen. Adjacent to the cam 62 is a disc 10, provided with oblong slots 12 which receive the portion 58.01! the extension 56. i 5

Another cam 14 supports the shank 88. The shape of the cam surface of cam 14' is not the same as that of cam 82. The cam 14 is provided with an off-set 18 which causes a slight rotation of the pin about the portion 58 of the pin when the shank 80 advances over the off-set I8, so as to give the pin an advance impulse forwardly, advancing the pin into engagement with the leading edge of the aperture of the record material. It is necessaryfor the pin 54 to rotate about the slot 12, which permits radial movement of the pin .with respect to'the platen; but does not permit circumferential movement of .portion 88 with respect to the platen.

ll by a spring 80, best shown in Figs. 7 and 9, which'is mounted outwardly of the pin shanks 88 adjacent to the slot of disc 10. Thus, it may be seen that the pins maybe advanced out Then,

the pin intothe leading edge of the apertures of the superposed sheets of material to accurately align the several sheets. At the end of the feeding operation, the pin is rotated 'outof engage.- ment with the leading edge of the record material, at which time it. is ready to be retracted without contacting the record material, the pin being retracted along a path substantially coincident with the radius of curvature of the record material.

The tubularsleeve'iB together with the cams 82 and I4 and the disc 10 may be rotated from operative to inoperative position and vice versa much the same as disclosed in the modification shown in Figs. 1 to 6 inclusive and the same as shown in 'Shermans Patent No. 2,000,649.

Referring to the modification disclosed in Figs.

14 to 17 inclusive, the end 8| of the platen 82 ably mounted upon the shaft l2to shift the pins from o'prativeto inoperative position and vice versa, much the same as shown in the previous modification. The shank 80 follows a cam groove 83 in cam 88 also fixedly carried upon the tubularsleeve 82.

The slot 81 in member 8| guides the extension 88 radially with respect to the platen. The shape of the cam grooves 83 and 98 are such as-to cause the pin 84 to advance into and be retracted from the record material substantially along the radius of curvature.

impulse, so as toadvance the pin into the leading edge of the aperture of the several strips of the record material to correctly align these and feed the record material in registry.

Just prior to the retraction of they pin from the record material, the cam grooves cause the pin to be retarded with respect to the advancement of the record material, to permit the pin to'be retracted without engaging the leading edge of the aperture, thereby preventing mutilation of the record material which is provided with aper-- tures somewhat larger than the feeding pins to An off-set I00 found in the cam groove 83 causes. the pin tohave an advancing permit the impulse movement of the feeding pins.

From the above'description it will be apparent that there is'thus provided'a device of the character described possessing the particular features but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages; In its broadest sense,-the invention consists in the provision of means for producing a lateral movement of the pins as such pins are being projected or retracted.
