7 Claims.

This invention relates'to autographic registers and more particularly to an improved feeding, aligning, and re-folding mechanism for continuous-form stationery used therein.

The primary object of the invention is to Drovide aligning means, such as register pins for engaging perforations in each form length of the stationery to register the same over the platen and to provide mechanism for disengaging the i stationery from each alternate form length of the stationery record strip which is projected into a record compartment. Thus it will be understood that the pins will allow one form length to be projected to the rear of the compartment and will i carry the next form downwardly so as to insure its proper re-folding beneath the feed mechanism.

Heretofore re-folding of this nature has been accomplished by providing a register perforation `in alternate form lengths and providing a yieldingly urged pin to engage said` perforation when it is presented to the feed mechanism. In the present invention no special perforations are provided.

The invention is illustrated in the preferred embodiment in the accompanying drawings, in which- Fig. 1 is a broken longitudinal sectional View of an autographic register embodying the invention taken as indicated at line I--I of Fig. 5; Fig. 2, a fragmentary longitudinal sectional view taken as indicated at line 2-2 of Fig. 5, and showing the differential cam mechanism for retracting the pins; Fig. 3, a broken longitudinal sectional View similar to Fig. 1 showing the pins being retracted at the beginning of a revolution to permit the record strip to be projected to the rear end of the compartment; Fig. 4, a view similar to Fig. 3 showing the mechanism after making about one and one-fourth turns from the position shown in Fig. 3 with thepins carrying the form to be refolded toward the front of the machine; and Fig. 5, a transverse sectional view taken as indicated at line 5 5 of Fig. 1".

In the embodiment illustrated, A designates an autographic register having a supply compartment A1 and a record compartment A2; B, feed mechanism for continuous-form stationery advanced from the supply compartment A1 to the record compartment A2; and C, differential cam mechanism for initially positioning the stationery` 1936, Serial No. 76,241

compartment and forming a support for the mechanisms B and C.

The supply compartment A1 is provided with a forwardly swinging door IIJ which is pivoted to the casing at II, to permit access to the compartment for loading, and is normally held in its closed position by means of a skeleton cover I2 which partially encloses the platen 8 and is pivotally mounted on the upper central portion of the casing. The supply compartment is provided with a guide roll I3 which is journaled in a pair of slots I4.

The record compartment A2 is provided with an upwardly movable cover I5 which is pivotally mounted on the casing at I6 and permits access to the record forms which are projected into the compartment by the feed mechanism. The upper front portion of the casing is provided with a divider'plate Il which serves to separate the record strip of stationery from the original copy which is dispensed by the machine.

The feed mechanism B comprises a crank shaft I8 journaled in the walls of the casing, carrying a pair of lower feed rolls I9 and equipped at its outer end with a hand crank 2l); and upper feed rolls 2| mounted on a shaft 22 journaled in a housing 23 provided at` the rear end of the skeleton cover l2. The crank shaft I8 is provided with a ratchet wheel 24 which is actedupon by a pawl (not shown) to prevent rearward rotation of the shaft. The outer wall of the casing is provided with a leaf spring 25 adapted to lock the crank 2i) when it is rotated to the position against the spring pressed plunger 26. Thus it will be understood, to operate the machine the plunger 25 is depressed and the crank will then be free to make one complete revolution whereupon it will again be locked by the spring 25.

The aligning and re-folding mechanism C has a pair of register pins 2T which are slidably mounted in holes provided in the lower feed rolls I9. The side walls of the wheels are provided with slots 23 which are impaled by pins 29 projecting laterally from the pin shanks to permit limited movement of the pins in the sockets. 'I'he pins are urged outwardly by compression springs 30. A pair of fixed cams 3l. are mounted on the transverse wall 9 by means of cap screws 32 and project rearwardly into the path of the pins 29 so that the pins will automatically be retracted from engagement with the stationery during a portion of each revolution of the crank shaft I8. The latter cams insure the retraction of the pins from the stationery when they reach the position shown in Fig. 4. This happens during every revolution of the lower feed rolls. In order to retract the pins at the beginning of each alternate revolution of the feed roll a jack shaft 33 is provided and has an actuating arm 34. The shaft is further provided with a pair of arms 35 which may be swung downwardly into the path of the pins 29 to retract the register pins 21. The crank shaft i8 is provided with a gear 36 which is in mesh with a cam gear 31 journaled on a forward extension of the wall 9 by means of a cap screw 38. The gear 31 has twice as many teeth as the gear 36 so that it makes but one revolution for each two revolutions of the crank shaft. The cam gear has a cam lug 39 which serves to operate the arm 34 to retract the register pins. As shown in Fig. 5, the jack shaft is provided with a torsion spring 40 which urges the arms 35 upwardly and the arm 34 into engagement with the cam lug 39.

When the crank 20 is in its normal locked position shown in Figs. 1 and 5, the register pins 21 extend upwardly above the platen 8 and facilitate initial positioning of the continuousform stationery 4| which is led from the compartment A over the platen into the bight of the feed mechanism. The upper strip 42 is directed above the divider plate l1 while the record strip 43 extends beneath said plate. The skeleton cover I2 may then be closed to the position shown in Fig. 1 and the device is ready for operation. After a set of forms have been filled in the plunger 26 is compressed and the crank 2B given one revolution to turn out one form length. As shown in Figs. 2, 3 and 4, the lower feed rolls have a flattened or out away portion 44 so that the pressure between the rolls is momentarily released while the perforations in the stationery are engaged by the pins 21. This enables the 40; pins to 'perform part of the feeding operation while free from the rolls and permit the forms to be brought into perfect register. After the rotationthe original form 42 may be severed by drawing upwardly against the tear-off edge 45 provided at the rear end of the skeleton cover I2. Assuming that the cam gear was so positioned during the first revolution of the crank that it did not operate to retract the pins, the pins will carry the record strip forwardly to the position Yshown in Fig. 4 where they will be retracted from the stationery by means of the fixed cams 3|. On the next revolution the cam gear will cause the arms 35 to retract the pins at the beginning of the feeding stroke and this will permit the next record form to be projected rearwardly in the compartment A2 as shown in Fig. 3.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:
