7 Claims, (Cl. 197-133) My invention relates to feeding and aligning devices for continuous forms as they pass through a writing machine and, more particularly, to such devices which'maybe embodied in the platen of an ordinary typewriter or tabulator and including pins arranged to be projected from the platen surface into successive engagement with the marginal portions of the form contiguous to each of a longitudinally extending series of punched holes.

In devices of this type it is necessary, if the superposed parts of the form are to be maintained in proper alignment and registry as they are passed through the writing machine, that the pins engagethe forward side of the punched holes 50 that, as the platen is rotated, the parts of the form will be moved evenly and simultaneously without any jogging or twisting which would tend to carry the various parts out of predetermined superposed position, particularly when a comparatively-large number of parts are included in a single form.

The objects of my invention are to provide a pin type aligning device which may be embodied in the platen of a writing machine with efficacy; to provide such a device which will operate efficiently to move continuous 'forms through the machine and maintain the various parts thereof in proper alignment and registry; to provide a device which will be cheap to manufacture and easy to operate; and to provide a device of this kind'which will have many points of superiority over those heretofore used.

In the accompanying drawings, wherein similar characters are used to designate similar parts, several different embodiments of devices including my invention have been shown. In these drawings: Fig. 1 is a plan. view of a typewriter with the pin type feeding device as a component part of the platen; Fig. 2 is a section along the line 2-2 in Fig. 1; Fig. 3 is an enlarged view of the platen and its included device and witha continuous form threaded therearound, all as shown in Fig. 1; Fig. 4 is a staggered section taken generally along the line 4-4 in Fig. 3;

- projection'and withdrawal of the pins comprises Fig. 5 is a side view of one of the parts, as will be fully explained below; Fig. 6 is a view, similar to Fig. 2, of a modified embodiment of the device; Fig. 7 is a section along the line 1 in Fig. 6; Figs. 8 and 9 show details of the construction of this embodiment; Figs. 10 and 11 show details of a third embodiment; and Fig. 12 shows a variation of the embodiment of Figs. 10 and 11 wherein the feeding and aligning pins have been changed somewhat in shape.

by the knurled hand knobs 4.

Referring to the figures, and particularly to Figs. 1 which my new and improved device is mounted has the usual carriage 2 for. the platen 3 rotated different embodiments shown and described in this application, my invention has been included in the platen of a typewriter, it should be understood that it may be adapted readily and easily for use with any kind of writing machine, such as tabulators, billers, or others having a platen around which passes a continuous form or other paper to receive written indicia.

In this instance, however, the continuous multipart form 5 is threaded around the platenv 3 in the-manner shown in Figs. 2- and 4v and has at each marginal edge thereof a longitudinally extending series of punched holes 6 which are "elongated and, preferably, are otherwise shaped as illustrated in-Figs. 1 and 3. At each end of the platen 3 is included an aligning unit 1 having an orbitally disposed and moving series of pins 8 adapted, when the platen is rotated, tov enter successively into the holes 6 of a series and engage the forward or leading side of each hole to move the form 5 with the platens surface.

-. As clearly shown in Figs. 2 and 4, the outer ends of the pins 8 throughout most of their orbital movement lie .within the circumference of the platen 3 but for a portion of their orbit these pins are projected outwardly from the platens circumference so as to enter the holes 6, .as described. The mechanism forcausing this the'followingparts: Each of the pins 8, preferably, as-shown, is shaped like a bell-crank and has one end pivotally mounted on a stud 9 carried by a plate l0 secured to an end of the platen ,move in and engage the side walls of a cam race or channel l3 formed in the plate I mounted, as on a hub l5 carried by the platen shaft l6, to remain stationary relative to the platen 3 as it rotates. That is, the plate l4 remains stationary relative to the fixed writing point of the machine. Obviously, when the platen is rotated the pins 8 will move orbitally and when the knobs l2 movein-the portionof to 5, inclusive, the typewriter l upon While, in the the channel l3 having the smaller radius the free ends of the pins will remain in withdrawn position below or within the circumference of the platen. However, when the knobs l2 move into the comparatively short portion of the channel having the greater radius, the pins 8 will be rocked outwardly to cause the free ends thereof to project beyond the circumference of the platen and to swing into the elongated holes 6 in'the continuous form 5 threaded around the platen. As shown in Figs. 2 and 4, the free ends of the feeding and aligning pins do not move radially outwardly but, as just described, swing into projected position and the leading edges of the pins do not contact the forward side of the holes 6 until the leading edges have assumed a radial position in which they engage simultaneously the contiguous edges of the registering holes in the various parts of the form. This manner of engagement is very important and is a step forward since it obviates the tendency, created by the other pin feeds heretofore used, to draw one or more of the superposed parts of the continuous form ahead of the other parts and, thereby, to carry the parts out of registry as the form moves around the curved platen.

Sometimes it may be desired to vary the relative point in the platens circumference at which the pins 8 are projected therefrom and, of course, such variations may be effected by rotating the plate l4 and its included cam channel l3 in relation to the platen. The means for maintaining the plate M in such adjusted position may include the spring impelled detent I! carried by and extending through the flange 29 fixed to the plate M. The lower end of this detent is adapted to extend into one of a series of holes 2| in the cylindrical portion of the part I8 which has a bifurcated arm engaging the tie rod IQ of the typewriter and through such engagement is prevented from rotating about the platen shaft Hi.

It will be evident, that when the detent I! is lifted out of one of the holes 2| the plate I4 may be moved relative to the part l8 and to the platen 3 so that the portion of the cam channel having the larger radius will be moved to cause the pins 8 to be projected outwardly at the desired relative point on the platens circumference as it is rotated. When the adjustment has been effected the detent is released and the spring thereon will cause the lower end thereof to enter the adjacent hole 2! in the cylindrical portion 20 of the part I8 and further movement of the plate l4 about the platen shaft will be prevented, as the device is operated.

Although the operation of this embodiment of my new and improved feeding and aligning device should be understood from the above description, particularly when taken with the accompanying drawings, for the sake of clarity a brief statement of such method of use and opera tion will be given here. After each unit I has been adjusted through the detents IT, as just described, to cause the pins 8 to be projected at the proper points in the platens circumference. a multi-part continuous form 5 is threaded through the typewriter or other writing machine in. which'my device has been embodied and around the platen 3. A usual guard 22 may be provided to support the form as it approaches the platen, as shown in Figs. 2 and 4. At all times, of course, several of the pins 8 of each unit 1in this embodiment three of the pins will be projected from the circumference of the platen and, as the form 5 is threaded through the machine, the holes 8 at each marginal portion of, the form are registered with the projecting pins so that the forward side of each of the registering holes in each form part is engaged by the leading edge of a pin. When the form has been moved through the machine into proper position for writing, the desired indicia is typed thereon and then the knurled knobs 4 are manipulated to turn the platen to carry the form into the next writing position. When the platen is rotated the co-operating knobs l2 and cam channel I 3 will cause thepins 8 to swing outwardly to enter successive holes 6 in the marginal portions of the form and the form will be carried with the platen and the various parts thereof during such movement will be maintained in proper registry and alignment. As stated above, in this embodiment the pins 8 swing outwardly as they are projected from the platens surface and, therefore, the holes 8 must be elongated to accommodate the free ends of the pins during such swinging movement. It is desired to change the point on the circumference of the platen at which the pins 8 are projected, the detent I1 is lifted away from the cylindrical portion 20 of each unit 1 and the plate I4 is rotated relative to the fixed writing point of the machine to effect the wanted-adjustment. If the feeding and aligning device is included in a power driven platen of a writing machine of a different type the operation will be the same. It should be noted that in the embodiment of my device shown in Figs. 1 to 5, inclusive, the feed pins 8 are both projected into form engaging position and withdrawn by the action of the knobs l2 in the cam channel I3.

In the modified form of device shown in Figs. 6 to 9, inclusive, however, the pins 8a are projected into form engaging position and are withdrawn therefrom by a positive gear drive and the cam action only guides them after they have been projected or withdrawn. Each pin 811 has a knob |2a co-operating with a cam race or channel l3a formed in the adjustable plate Ila. As clearly shown in Fig. 9, this cam channel is widened at the connections between the portions of smaller and larger radius so that the knobs at these transition points in their paths of travel are not moved outwardly or inwardly by the channel as the platen isrotated. In this embodiment the outward and inward movement of the pins 811 is effected in the following manner: Each pin 8a has extending therefrom a pivoted link 23 connected at its other end to a finger 24 fixed to a face of a small gear 25 mounted on a stud 26 on the plate l0. Fixed to the adjustable plate I 4a at the outer periphery of the orbit of the pins 8a, is a rack 21 and at the inner periphery of the orbit is arack 28. These racks are arranged and positioned to engage and mesh with the gears 25 as the platen on which they are carried rotates relative to the plate Ma on which the racks are mounted. When the platenis rotated in the direction indicated by the arrow in Fig. 9 the rack 21 will mesh successively with the gears 25 and will turn or rock them to cause the finger 24 to move the-link 23 to swing the pins 8a into projected position, as shown in Fig. 8. Then, as rotation of the platen continues, the gears 25 will be carried successively into engagement with the rack 21 and the gears will be turned or rocked in a reverse direction to cause the pins 8a to be withdrawn. Complete rotation of the gears 25 in either direction is prevented by the knob |2a moving in the channel I3c. Except for this variation in the motivating mechanism for the feeding and aligning pins, the operation of the embodiment illustrated in Figs. 6 to 9, inclusive, is the same as that of the previously described embodiment.

In the embodiment shown in Figs. 10 and 11 each of the pins 8b has the form engaging shank thereof arranged at substantially a right angle to the shank pivoted to the plate l; each has the leading and rearward edges of the form engaging shank tapered to a blunt point; andeach knob I21) and the co-operating cam channel l3b formed in the plate Mb are arranged and positioned so that when a pin is swung into projected position the end thereof passes through an are including a round hole 6b in the multi-part form 5. In other words, with this embodiment of my invention it is not necessary to use elongated holes in the marginal portions of the form since the'pins swing so that the tapered free shank will pass through the round hole 6b, as shown in Fig. 11 where the progressive movement of a pin has been illustrated. However, as also shown in 'this figure, it should be noted that the leading edge of the free shank of each pin lb, even though it passes through a round hole Ob, does not engage the edges of the contiguous portions'of the multi-parts of the form at the forward side of a hole until the pin has been projected fully outwardly and the leading edge of the free shank is extending radially of the platen.

The variation of the device shown in Fig. 12 is the same as that just described except that the form engaging shank of each pin 80 is tapered from all directions so as to be cone shaped but, otherwise, the pins 80 andthe co-operation of the knobs I20 and the cam channel I30 in the 'plate Me is such that the free shank of the pin will swing outwardly into engaging position within the area of a round hole 6c formed in the. marginal portion of the continuous form 5, in the same manner as in the embodiment of Figs. and 11.

In the accompanying drawings, as stated hereinbefore. I have shown severalembodiments of feeding and aligning devices including my invention but, of course, I do not intend to limit myself to the embodiments shown herein. The shape of the pins, the method used for motivating them into projected and withdrawn positions, and the size, shape and arrangement of the other parts of the device may be varied within wide v ranges without deviating from the spirit of my invention as bounded by the ambit of the appended claims.
