3 Claims. (Cl. 282-12) This invention relates to registering apparatus for continuous stationery particularly for use in hand writing machines or autographic registers. Each set of forms into which the continuous stationery is divided by transverse line of perforations are registered in position on the writing plate by means or retractable pegs or pins on the machine which engage registering holes in the forms of the stationery, After the forms have been filled in, the continuous stationery is advanced to bring the next set of forms into register with the pegs or pins and the used form-s are torn oif along the superposed lines of perforations. Carbon paper is interleaved and arranged to pass transversely across the writing table. This invention has for its object to ensure that the sets of forms will not be torn or damaged at the punch holes. By this invention, a definite clamping grip is applied to the stationery, so that pressure of the edge of the registering holes on the pegs is relieved whilst sections are torn oir.

Figure 9 is a face View on the inside of the box showing the means for mounting the registering pegs and the clamping means and Figure 10 shows a portion of superimposed sheets of continuous stationery, and Figure 1l is an enlarged view of the clamping device shown by Figure 7.

According to a convenient embodiment of this invention, the superposed continuous sheets of stationery 1 (indicated by the broken line on Figure 3) are guided over a writing plate 2 and under the cover plate 3 having an opening 4 through which the writing on the stationery takes place and guided in lateral guides 9. The continuous stationery is housed in the body of the box 5 and passes up through the opening 6 at the back of the writing plate 2. At t-he front of the Writing plate 2 the stationery passes between plates 7 and 8, the plate 7 being xed to the top of the box 5 level with the writing plate 2 and the plate 8 being fixed to the underside of the cover plate 3. The edges of the continuous stationery pass under the curled over edges or guides 9 of the plate 7. The lower plate hastwo holes 10 ICC therein, and lbelow this plate a pivoted arm or spring pressed retractable member 11 carries two registering pins 17, the arm 11 being mounted on a bracket-12 xed to the wall of the box 5. The pivoted arm has a coiled spring 13 on its pivot pin 14 which normally urges such member into position with the registering lpins 17 projecting through the said perforations 10 in the bottorn plate 7 for engaging registering holes A punched in the continuous sheets 1 and in this position the pins pass through holes 15a and enter recesses 15 in the cover plate 3 lying over the stationery. In the registering ,position as shown by Figure 3, the pins incline forward Islightly and substantially tangential to the arc of movement about the pivot pin r14. Mounted on the pivoted member forward of the pins and adjacent thereto aretwo sheet gripping or clamping jaws, conveniently in the form of toothed plates 16 which, when the pins 17 are in the registering position pass through slots 18 in the bottom plate 7 and press against the continuous sheets 1, the top plate 8 having recesses 19 opposite the toothed plates to ensure a good grip. The front edges ofsaid top and bottom plates 7 and 8 have notches 20 therein, so that the front of the continuous stationery can be gripped 'by the ringer and thumb to pull the stationery through the machine. The pivoted arm 11 carrying the pins 17 and grippers 16 is depressed by a tongue 'or -iin'ger operated means 21 thereon which normally lies under the notches, whereby the tongue 21 must rst be depressed before the nger and thumb can grip the stationery and the tongue is depressed by the hand gripping the stationery. As the stationery is being pulled out the hand slides oi the tongue 21 and the registering pins 17 move back and bear on the underside of .the stationery to automatically ride into the next set of perforations. The friction caused by the pins 17 bearing on the stationery 1 and pressing such stationery against the plate 8 ensures that the stationery can be pulled out steadily. The diameter of the punch holes in the stationery are larger than the diameter of the pins 17, so that pins 17 snap into engagement with the punch holes in the stationery and form a dead stop. The pins are rounded at the top and the height of the toothed plates or jaws 16 is less than thatof the pins so that they are free from the stationery until the pins enter the punch holes in the stationery. The transverse lines of perforations 3 dividing the forms are in register with the outer edge of the top plate 8 when the stationery is registered by the pins 17, so that the set of forms can be torn off along the edge of the plate 8. As the pointed ends of the gripping jaws 16 rmly grip the stationery adjacent the pins 17, Whilst a set of forms are being severed, the punch holes in the stationery are not damaged and registration of the forms is maintained.

The said bottom plate 7 having the openings for the pins and grippers is mounted on the bracket 12 carrying the pivoted arm 11 to facilitate building machines having different widths of forms.

With the aforedescribed construction, the spring retracta'ble member must be released so that the pins 17 are free to engage the next set of punch holes A in the continuous sheets 1, and as the pins 17 have a hooked engagement with the punch holes in the sheets, there is no liability of the punch holes jumping over the pins 17 by quick withdrawal movement of the continuous stationery.

The construction shown 'by Figures 6 to 9 is similar to the construction shown by Figures l to 5 except that a modified construction of clamping means are incorporated. The retractable member on which the registering pegs 17a are mounted comprises an arm 22 whichis pivotally mounted on a support 23 which itself is pivotally mounted on the bracket 12a mounted on the body of the box 5. The arm 22 is spring pressed upwardly by means of helical springs 29 and the pivoted support 23 is spring pressed inwardly against the wall 0f the bracket 12a by helical springs 3d. The clamping jaws comprise knife edged plates 24 which are pivotally mounted on the wall of the bracket 12a and a rod 25 on the underside of the arm 22 extends through slots 26 in `the 'walls A27 ot' the bracket 12a and engage slots 28 in side lugs 23a on the plates or arms 24. When therefore the arm 22 .is depressed by pressure on. the tongue 421a the registering pegs 17a are retracted from engage ment with the registering or punch holes A in the continuous stationery or sheets it and at the same time the clamping plates or jaws 2d are pivoted in a direction away from the clamping position. When the registering pegs are engaged through the punch or registering holes in the stationery, the plates 2d are raised. into the position shown `by full lines Figure 7, but the clamping edge of each plate does not clamp on the stationery which passes under the turned over end 9a of the plate 7a. The clamping edge of each plate 24 passes through a slot 28d in the plate 7a. A set of forms of the stationery having been written on, the stationery is pulled through the machine until the pegs 17a enter the next succeeding holes A in the lstationery and the pressure of the edge of such holes on the pegs 17a moves the arm 22. `forwardly as it is pivotally mounted on the member 23 and the rod 2S raises the clamping plates 241 into position (shown by dotted line Figure 7) gripping the stationery again-st the underside of the turned over ends 9a, such ends having slots 9b therein opposite the gripping edges of the plates 24 to assist the gripping action. rihe stationery moved forward can then be torn oi along a line of perforations B and the pull on the stationery during act of tearing nolds the plates 24 vin the gripping position and thus avoids the liability of tearing the stationery at the punch holes A engaged by the registering pegs. in this construction, the superposed layers of stationery are automatically pulled into exact register as they are pulled against the pegs before the clamping is effected and the upwards pressure of the springs 29 holds the plates 24 in the clamping position until the nger piece 21a is depressed for the next feed forward of the sheets.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A writing machine incorporating registering apparatus for continuous stationery having registering holes at intervals along the stationery, comprising a support over which the continuous stationery travels, a retractable device having a pivotaily mounted arm with registering pegsvthereon, spring means for pressing the arm in a direction towards said support to engage said pegs in said registering holes inthe stationery lying over said support and finger means for retracting the arm to disengage said pegstfrom said holes, a member xed inrelation to said support between which member and support the stationery lies, and a clamping device for clamping said stationery against said member to prevent movement of the stationery whilst a section is being torn off and with the pegs in engagement with registering holes in the stationery, means for mounting said arm of the retractabie device with the registering pegs thereon so that such pegs are forwardly movable whilst in engagement with the registering holes by a pull on the stationery and means operated :by the forward movement of the said pegs for moving the clamping device into the clamping position.
