UNITED STATES PATENT OFFICE.

JESSE A. B. SMITH, OF STAMFORD, CONNECTICUT. ASSIG-NOR TO UNDERW'OOD TYPE WRITER COMPANY, OF NEW YORK, N. YJ, A CORPORATION OF DELAWARE.

TYPEWRITING MACHINE.

Application filed March 31, 1921.

To all whom it may concern:

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States. residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to collating devices,

and is in the nature of an improvement on the patent to B. C. Stickney, et al., No. 1,295,383, granted February 25, 1919.

In Underwood standard typewriters, feed-rolls to co-operate with the platen are supported by arms or levers loosely mounted on a rod extending from end to end of the platen-frame, and provision is made of a cast-off shaft having flats thereon with which the supporting arms co-operate when the feed-rolls are in their effective positions. This shaft is provided with an arm, usually at its right-hand end, and a link connects the arm to the usual release-lever, actuation of which will rock the cast-0E shaft and withdraw the feed-rolls from the platen.

In carrying out the invention, provision may be made of a collating table extending upwardly and rearwardly from the delivery side of the platen and having a side-edge so gage at its left-hand edge. Clips may also be provided to hold work-sheets against the collating table near the side-edge gage, and

these clips may be yieldably held, as by springs, in either effective or ineffective position. The'clips, when in efiective position, may be restored to inefiective position by suitable means, such as a bail extending along the same.

The feed-rolls and clips maybe controlled.

40 by a single manually-operable member,

preferably in the form of a pivoted fingerpiece. To this end, the cast-ofi shaft may be provided, preferably at the end opposite to that connected to the cast-01f or releaselever, with an arm, and to this arm may be attached a link having a fiat or plate-like upper end, a straight edge of which is held in guiding relation with the pivot of the finger-piece by suitable means, such as a spring. Connection between the pivoted finger-piece and the link may be efiected by Serial No. 45 7,372.

means of a projection or stud on the former engaging in slots in the flat head of the link. In order to permit release of said cast-01f shaft without shifting the finger-piece, the upper end of the link is provided with a vertical slot so that, when the finger-piece is positioned with-its stud at the upper end of the slot, the feed-rolls may be cast off by the usual release-lever, the slotted link mov ing idly with reference to the finger-piece.

.To enable the feed-rolls to be cast off or released by the finger-piece, the flat end of the link is provided with a slot leading from the upper end of the first slot and in such a direction that, when the finger-piece is swung to carry the stud into the last-mentioned slot, the link will be lifted sufliciently to cast off the feed-rolls.

Upon the return of the finger-piece to its normal or neutral position with its'stud at the upper end of the vertical slot, the feedrolls will have been restored to their'eife'ctive position. It may then be desirable to actuate the bail to restore any effectively positioned clipto ineffective position. To this end, the flat upper end of the link is provided with a slot extending from the upper end of the vertical slot and extending in an arc of a circle about the pivot of the finger-piece so that the finger-piece may be shifted without shifting the link to engage a member connected with the bail and actuate the same. It will be seen'that, dur ing the movement of the stud through the last-mentioned slot, .the link and cast-off shaft will be locked against movement.

Other features and advantages will hereinafter appear.

Inthe accompanying drawings,

Figure 2 is a sectional view, taken from above, of the mechanism shown in Figure 1,

certain .parts being omitted.

Figure 3 is a detail view of certain parts shown in Figure 2, indicating the manner in which the clips are yieldably held in either efiective or ineffective position.

Figure 4 is a sectional-side view, showing all the parts in their normal positions.

Figure 5 is a view similar to Figure i, but with the teed-rolls cast of? and the clips in closed or effective position.

Figure 6 is a view similar to Figure 5, but showing a clip closed.

Figure 7 is a view similar to Figure 6, but with the controlling finger-piece shifted to its extreme forward position, to restore the feed-rolls to effective position relative to the platen, and to return all efiectively positioned clips to ineffective position.

A platen 1 is rerolubly supported by means of an axle 2, journaled in the ends of a platen-frame 3, and the platen 1 may be rotated either by a hand-knob lor by line-spacc mechanism, comprising a linespace wheel lVork-sheets may he gripped to the platen 1 by means of front and rear feed-rolls 6, the front feed-rolls 6 being carried on a shaft 8, supported by levers 7, which are rotatably mounted on a rod 9, connecting the ends of the platen-frame, and the rear teed-rolls 6 being carried by a shaft 10, supported in levers 11, rotatably mounted on said rod 9. The lovers 7 and 11 are provided with downwardlyextending arms 12 and 13, respectively, which normally lie adjacent fiat surfaces or flats on a rock-shaft 14-. The shaft 1% may be provided at one of its ends, preferably at the right, with an arm 16, which may be connected by a link 17 with the usual cast-off or release-lever 1S. Normally, the feed-rolls 6 are held in engagement with the platen. 1, as seen in Figure 4, by means of springs (not shown), and, when the cast-oif'lever 18 is depressed, by means of its finger-piece 19, the link 17 will be drawn upwardly and the rockshaft 1% turned to the position shown in Figure 5, thereby casting off the feed-rolls.

A collating table or front paper-table 20, having its lower edge. adjacent the platen and extending upwardly and rearwardly from the delivery side of the platen. may be supported. on the platen-frame in any suitable manner. The collating table is provided at its left-hand edge with a side-edge gage 21. in whichare notches 22, to receive suitably-shaped clips rotatably mounted on a rod 24. lying outside of the side-edge gage 21 and parallel thereto. the clips 23 being held in either effective or ineffective position by means of springs 25, secured to the back of the table 20 in position to engage fiat surfaces 26 and 27 on the hubs of the clips accordingly as the clips are in effective or ineffective position. The rod 2% is supported in brackets 28, secured. to the side-edge gage 21.

In practice. the feed-rolls 6 are in castofi' position while the sheets are being collated or adjusted on the table 20. and. the clips 23 are manipulated. in any manner desired. to assist in holding the collated sheets in position, but, when the feed-rolls are restored to the platen, to enable the collated sheets to be fed forward together, all of the clips should be released. In order to insure release of all the clips when the teed-rolls are restored to the platen, and to obtain co-ordination between the parts, provision may he made of a manually-operable member or handle 32, pirotally mounted. on a stud 3O projecting from a bracket 31 on the adjacent end of the platen-frame 3. and having a stud 33 thereon projecting into a three-part slot 3% in a flat portion or plate 3;) at the upper end of a link 36, which is connected at its lower end to a second arm it) at the left-hand end of the bait 11 The link 36 may be guided in ts reciprocating movement by means of a straight edge on the plate 35, which engages the stud 30, and is yield-ably held in contact therewith by means of a spring connected at one end to a pin on the plate and at the other end to a pin on the bracket- 31.

When the handle 82 is in its normal or neutral position (shown in Figure 4C)., it will lie at the upper end of a vertical slot 39, forming one branch of the three-part slot 3%, and, it the cast-oft lever 18 is operated, the link 36 will have an idle movement with reference to the stud 33, the front and rear feed-rolls 6 being cast of? in the usual manner. If, however, the handle 32 is depressed from theposition shown in Figure 4 to that shown in Figure 5. the stud 33 will move forwardly in a slot slsubstantially at right angles to slot 39, and the link 36 will be raised so as to cast oif the teed-rolls 6, as seen in Figure 5.

The handle 32 may also be used to restore to ineiiective position one or both of the clips 2 which may be effectively positioned to hold work-sheets against the lable 20. To this end, a bail -11 may be mounted on rod 21- and an arm 42 on the bail connected by a. link 43 with a bell crank-lever 4.4.. mounted on the stud 30, and having a pin i5 extending across the path of the handle 32. il hen one or both of the clips 23 is depressed, the bail will be shifted to its lowest position, the link 43 will be raised. and the bell-crank-lever 4 lshifted to the full-line position, shown in Figure 6. It. then. the handle 32 is restored from its Figure 6 to its Figure -l position, the Feed-rolls 6 will be restored to effective position with the platen. and. upon further movement ol the handle 32. the stud 2 will travel along a slot 46. forming part of the three-part slot 34;. the slot as being so shaped as to he concentric with the stud 30 when the link 36 is in its Figure l position, thereby permitting movement of the handle 32 without shifting the link. During this part of its movement,

the handle 32 will engage the pin 45 and move the bell-crank-lever 44: from the position shown in full lines in Figure 6 to that shown in Figure 7, thereby depressing the link 43 and rocking the bail 11 to insure the restoration of clips 23 to ineffective position.

In this connection, it will be seen that, as soon as the stud 33 enters the slot 46, the link 36 will be locked in its depressed position, and actuation of the shaft 14 by the. cast-off lever 18 will be. prevented. Furthermore, if the link 36 has been lifted due to the actuation of cast-off lever 18, the handle 32 will be locked against movement in the direction to engage pin f5 and restore the clips 23 to their ineifectiveposition. \Vhen link 36 has been lifted by means oflever 18 so that stud 33 lies in slot 39, any attempt to actuate handle 32 in a clockwise direction (Figure 4) will urge plate35 against the fixed stud 30. Although only two clips 23are disclosed, it is obvious that a larger number may be used if desired.

In practice, a record or proof sheet is kept in the machines and ledger and statement sheets are inserted and collated on the outside thereof when entries are to be made. During this operation, the feedrolls are in released or cast-off positions so as not to interfere with the relative shifting of the work-sheets, and the clips are shifted as desired to their effective position to hold the collated sheets in position on the collating table. Upon completion of the collating operation, the feed rolls are restored to the platen and the clips are shifted to ineffective or released position. In order that the work-sheets -may always be under control, the mechanism is so designed that handle 32 cannot be moved to a position to release the clips 23 until the feed-rolls 6 arerestored to positions to enable them to co-operate with the platen, irrespective of the casting off of the feedrolls 6 by handle 32 or finger-piece 19. That is to say, the handle 32 when used to cast-off the feed-rolls 6 must be moved to its neutral position to restore the feedrolls to their effective positions before it can be moved to release any of the clips which may be in effective position, and, if the feed-rolls 6 are cast-off by finger-piece 19, handle 32 will be locked against move ment to release the clips.

The work-sheets may be inserted at the front of the platen. In this case, the sheets are first placed upon the collating table and gaged under the clips, their lower ends being then slipped down at the front of the platen into the space between the platen and the feed-rolls.

It may be desirable not to place the top sheet, which is to have the ink ribbon impression, under the clipsl This sheet may then be held in position on the platen by hand until the feed-rolls, which have stood released during. the collating operation, have been restored.

Variations may be resorted to within the scope of the invention, and portions of the mprovements may be used without others.
