JAMES D. MoCOY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPE-WRITING MACHINE.

Application filed February 21, 1913.

In a?! whom it may concern:

Be it known that I, JAMES D. MCCOY, a citizen of the United States, residing in Boston, in the county of Suii'olk and State of Massachusetts, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates to typewriting machines, and is herein disclosed as applied to an Underwood typewriting machine. Such machines are being used for purposes of bookkeeping, even in small oilices where the machine is only used for part of the time for this purpose, and in such methods of bookkeeping it has hitherto been customary to make the ledger-sheet in the form of a carbon copy of the original statement or bill. Under some conditions, especially in small businesses, where the ledger-sheet is likely to remain only partly filled for a very long time, so that the carbon impressions thereon might become smudged from handling, it has been found desirable to make the ledger-shect an original while the statement is in the form of a carbon copy. Since the ledger-sheet is usually wider than the statement-sheet, the ledger-sheet, when being adjusted, will often completely conceal the statement-sheet on which the carbon copy is to be written, thus rendering it difiieult to aline or register the statement and the ledger-sheet. v

To overcome such difiiculties of collation or alincment, and also to overcome certain other analogous diflicultics, I provide a frontcollating table on which a statement-sheet may be adjusted and alined against the end gage and then held in such position of alinement while a ledger-sheet is being adjusted in front thereof.

To secure the necessary accuracy of adjustment of the statement-sheet, the table may be provided with both an. end and a side gage and also a device adapted to hold the sheet against either the end or the side gage, or both, while another sheet is being adjusted in front of the statement-sheet. Since the end gage is useful not oniy in writing statements but also may be useful in alining letters and other work-sheets, such as are frequently used when the machine is not being used for bookkeeping, the end gage is made adjustable so that it may serve for the Specification of Letters Ratent.

various kinds of work-sheets which the machine is likely to be used for.

According to my invention, the holdingdevice for keeping the statementsheet in posltion may be swung clear of the statement-sheet and clear of the ledger-sheet, after the ledger-sheet has been clamped in position by the usual feed-rolls. Then the usual feed-rolls will feed the ledger-sheet and the statement-sheet around together.

In order to obtain a structure for filling the above requirements, it might be supposed that the added wei ht of the necessary structures on the typewriter carriage would seriously interfere with the ease and quietness of the operation of the machine. I have found it, possible, however, to provide that the adjusting table, such as has been shown in prior applications, may carry an adjustable-feed-roll at each side which forms the holding device. and which may be thrown around to incfl'cctive position at any time. The upper end of the adjusting table may have its ends extended into the form of bentover cars, which adapted to support rods on which the end gage may be adjustable. Thus, the structure that carries the mechanism for adjusting the end gage is both light and out of sight and entirely out of the way of any work-sheets, but it maybe easily reached if the typist puts his fingers around the end of the adjusting table.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective front view, showing my device as applied to the carriage of an Underwood typcwriting machine.

Fig. 2 is a sectional side view of the same.

Fig. 3 is a fragmentary rear perspective, showing the mounting of the end gage.

The usual platen 10 of the Underwood typewriting machine is mounted on an axle ll, which is journaled in the end plates 12 and 13, and provided at its outer ends with knobs 14 by which it may be turned. In addition to this, it is provided with the usual line-space lever 15 variably effective by the usual connections on the usual line-space wheel 16.

A statement-sheet 17 may be inserted from the rear over the usual paper table 18 after casting off the usual feed-rolls .19 by the handle 20. The statement-sheet then may side-gage 21 until guirpose desired in this be ushed around up at the front of the mac ine with its edge against a right-hand its end strikes an endgage 22 which is adjustably mounted on a collating or adjusting table 23. The statement-sheet may be then clamped in place by swinging the holding device (shown in the form of a roll 24) around the rod 25 until the device bears against the statement sheet 17 and holds said sheet in lace. The table 23, as shown, is supported aibove thefront of the platen 10, and slopes rearwardly so that sheets lie thereon at a convenient angle for adjustment. It is supported in this position by brackets 26 to which it is firmly held by screws 27 which are screwed into cars 28 of the brackets and engage the surface of the table 23 at depressed portions 29, large enough and deep enough to accommodate the heads of the. screws 27, with the result that a work-sheet will slip, clear of the screw heads, smoothly over the table formed by the surface 23.

After the statement-sheet 17 is adjusted in place, a ledger-sheet 30 may be adJusted in place by insertion in the usual manner over the rear paper table 18 up past the usual feed-rolls 19, and may be gagcd against either or both of the side-gages 21 by means of a scale plate 3'1 forming part of each. If desired, in addition, one or more work-sheets 32 may also be inserted for any form of bookkeeping.

etween these sheets are inserted the usual carbon sheets. The edge-gage 21 is long enough so that sheets may be accurately gaged sidewise thereagainst, eyen though they bend over the roll 24 and its mounting 32, and extend beyond the end-gage 22.

To enable this to be done, the roll 24 is placed at thelower extension of the boxframe 33 which forms a part Of ItS mounting, and the upper edge 34 of said frame is the only point of the frame which pro ects above the gage 21. The box-frame 33 is held steady by the arm 34, because said arm is extended downwardly as at 35, after it encircles the rod 25 at the point 36 and then is turned up again at 37 to embrace said rod; thus, the extension forms a bail embracing the rod 25 at each end.

In order to hold the roll 24 and its mounting in pro er position on the rod 25, there is provide a spring 38 which bears against the bail and the rod 25. This structure enables the roll 24 to lie beside the gage 21 a considerable distance below the piece 34, thus requiring very little curving of a worksheet to .pass over the piece 34.

When all the work-sheets have been adjusted, the usual feed rolls 19 are thrown on by the handle 20 and then the roll 24 is swung around to position above the worksheets, where it is shown in Fig. 1, clear of the Work-sheets, to enable them to be easily which support the plate forming the fed along over the paper table 23 by the usual line-space mechanism.

In order to enable the mechanism to be of as broad utility as possible, there is provided a roll 24 slidably mounted on a rod at each side of the paper table 23, so that any or all work-sheets can be adjusted against either the left-hand turned-up edge 21 or the right-hand turned-up edge 21.

In, order to enable statementsheets with varipus sized headings to be adjusted on this table 23, which is necessary in many kinds of business, the leadingfedge gage 22 is adjustably mounted, as above stated, and to enable this mounting to be made so light as not to materially add to the weight of the typewriter carriage, the table 23 is provided, at its upper end, with rcarwardly-turned cars 39* in which are mounted rods 40 tending behind the table 23 but parallel thereto, and on these rods is slidably mount ed a plate 39 which carries the gage 22 at its upper end. 7

To enable this gage to be easily adjusted and yet to be firmly held at any desired position, it is rovided with a wing 41, at each side thereo on which is fast a slide 42 having at its opposite ends two turned-up cars 43 embracing 42 also having a boss 44 in which is mounted a spring-pressed ball 45 adapted to bear against a slot 46 in the rod -l0, thereby gaining the required friction. Since each of the cars 43 embraces the rod 40, the plate 39 is compelled to move with its upper edge always parallel to itself.

Owing to the fact that the table 23 serves as the surface on which the work-sheets are adjusted. the plate 39 need not cover the whole of the opening across which the gage 22 moves. This enables the plate 39 to be made considerably smaller and thus lightens the structure.

For ease in assembling, the rods 40 are held in place at their upper ends by screws 47 which pass through the cars 39 and they are also held in place at their lower ends by screws 48 which pass through the lower cars 49, the latter being in the form of turned-up edges of plates 50 held by screws 51 entered into the plate 23. For convenience in alining, the machine includes the usual wing scales 52 adapted to show the line at which the type 53 will print. The brackets 26. table 23, may be mounted in one of the usual manners, for this purpose being fast on a transverse rod 54 which is fast in the shift frame.

In order to steady the brackets 26 they are formed at their upper ends at 58 to unibrace a rod 59 mounted in the bracket 55 which is hold in the shift frame by the usual screws 56 passing through the slots 57 in the brackets.

Variations may be resorted to within the the adjacent rod 40, said slide scope of the invention, and portions of the side gages, work-holdin -devices slidably improvements maybe used without others. mounted outside of saig side gages and aving thus described my invention, I adapted to b thrown to effective or inef- 55 claim: fective position around their slidable 1.
