5 Claims.

This invention relates toapparatus for feeding continuous manifold forms through a typewriter, and is particularly adapted for use in feeding continuous fanfolded forms, wherein a transfer sheet pack is intended to be used. A pack of such nature is illustrated, described and claimed in an application for Letters Patent of the United States, Serial No. 694,993 filed October 24, 1933' by Clarence M. Hepp. Briefly, the pack referred to includes a plurality of transfer sheets that are connected together so as to admit the forms therebetween and so as to shear the longitudinal folds, while the forms are being drawn through the machine with reference to the pack.

The apparatus of the present invention has for one of its objects the provision of mechanism by means of which the forms may be conveniently pulled through the machine with reference to the pack, and by means of which the pressure exerted on the form is evenly distributed during such operation. An additional object is to provide apparatus which can be readily attached to the carriage of a typewriter.

Referring now to the drawings, Fig. 1 is a perspective view of a typewriter having apparatus embodying my invention mounted thereon; Fig. 2 is a front view on an enlarged scale of the apparatus shown in Fig. 1; Fig. 3 is a section taken on the line 33 in Fig. 2; Fig. 4 is a section taken on the line 4-4 in Fig. 3; Fig. 5 is a section taken through the typewriter platen and illustrating the method of moving the forms with reference to the pack, and Fig. 6 is a top plan view of the pack; Fig. '1 is a section taken on the line 11 in Fig. 6; Fig. 8 is a section similar to that illustrated in Fig. 3 but showing a gripper with forms therein, and in a position illustrated in Fig. 5.

In Fig. 1, I have illustrated a typewriter I0, as having a carriage I I, in which a platen I2 is suitably mounted. The carriage supports a frame that is shown, as having a base member I3, 21 pair of guides I 4 and struts IS. The guides extend vertically adjacent the center of the platen and near the forward edges thereof, and provide a trackway for a slide l6 that operates to grip the forms during the pulling operation. The gripper illustrated comprises a lever 20 which is pivotally mounted at 2! on a bracket 22 that extends forwardly from the slide, as is shown in Fig. 3. The outer end of the lever has a push rod 23 pivotally connected thereto, as at 24, and the lower edge of such rod terminates in a ring 25 through which the finger of an operator may be inserted.

The function of the gripper is to pull the forms,

indicated at in Fig. 8, while the transverse strips 3| which form part of a pack 32 are held in stationary position. For purposes of illustration, the means for holding the pack stationary comprises fiexib-le strips 32, which extend from one end of the pack and are looped around the bar 33 that is movable with the typewriter carriage. Normally the weight of the push bar holds the gripper in the position shown in Fig. 3, but whenever the bar is pushed upwardly to the position shown in Fig. 8, the lever 20 will bind against the forms that are inserted between it and the backing plate 35, thus effecting an automatic grip during the upward motion of the bar. The pack 32 has cutting edges, such as celluloid strips 35, for slitting the longitudinal folds of the forms, and so it is necessary to obtain a uniform distribution of pressure during the pulling movement. This is obtained with my apparatus, for the gripper engages the center of the forms and substantially at a single point. The forms thus automatically center themselves with reference to it.

The operationof my invention is, as follows: The operator inserts the transfer pack into the first set of forms, after such set has been slit manually along the longitudinal edges. The pack is then threaded through the machine and the straps are fastened tothe bar 33. After the form is used, the friction grip on the platen is released and the forms, exclusive of the transfer sheets, are inserted beneath the gripping lever 20, and a finger of the operator is inserted in the ring 25. Thereupon, the operator pushes upwardly until the used set of forms passes the upper ends of the transfer sheets. The pack with the new set of forms is turned backwardly until the top is in position for typing. At such time, the used set is torn off on the customary perforated lines. Thereafter, the operation is continued until the forms are all used.

I claim:

1. A manifold form feeding device, comprising in combination a typewriter having a carriage and a platen, a guide, means for mounting it upon the carriage, the guide being extended upwardly from the platen, a slide movable along the guide and a gripping fingerpivoted to the slide, said finger having a push bar attached thereto which normally holds the finger away from the slide but which grips the form and raises the slide whenr ever upward pressure is applied to the push bar.

2. A manifold form feeding device, comprising in combination, a guide extending upwardly from a machine through which a form is to be fed, a form gripper operated by an extended arm movable along the guide, said gripper being normally held in released position, but being adapted automatically to engage and hold the form when the arm is pushed upwardly by an operator.

3. A device for feeding manifold forms through a machine that has a frame and a carriage movable with referenee to the frame, comprising a guide, means for attaching the frame to the carriage adjacent the midportion thereof and a form gripper movable along the guide, the gripper including an extended arm attached to a member that is adapted to engage and clamp the form whenever upward pressure is exerted upon the arm.

4. A device for feeding manifold forms through a machine that has a carriage associated therewith including a guide, means for mounting the guide adjacent the center of the carriage, a gripper movably mounted on the guide and includhaving a push bar with a finger engaging portion at the lower end thereof and being adapted to force the lever into gripping position and raise the slide whenever pressure is exerted upwardly on the push bar by an operator.

5. A device for feeding manifold forms through a machine that has a carriage through which the forms are adapted to be fed, comprising a frame that is carried by the carriage, a guide mounted on the frame adjacent the center of the carriage, a slide movable along. the guide, a form gripper pivotally mounted on the slide, and a handle attached to the gripper, the gripper being normally held out of gripping position, but being adapted to be moved automatically into gripping position and also raise the slide whenever upward pressure is exerted thereon by a finger of an operator.
