EDWIN BARN EY, OF NEW ROCHELLEiNEW YORK. ASSIGNOR T REMINGTON TYPE- 'WRITER COMPANY, 0F ILION, (NEW YORK, A CORPORATION OF NEW YORK.

TYPEWBITING MACHINE.

To all 'whom t may concern.'

Be it known that I, EDWIN E. BARNEY, citizen of the United States, and resident of New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in 'Iypewriting Machines, of which the following is a specification.`

My invention relates to typewriting machines, and more particularly to a small, compact, portable machine intended to be transported or carried in its carrying case, such a machine, for example, as the Remington portable machine.

In portable machines it is desirable to confine the length vof the platen as unich as possible, consistent with the requirements for writing on aper of standard widths, and to according y confine the length ofthe carriage in order not to, exceed the necessary widthwise dimensions of the machine. One difficulty, however, that presents itself in thus restricting the machine to taking paper of approximately standard widths, is that work sheets of reater widths, and more particularly standard large sized envelopes cannot be introduced into the machine without folding them, which is undesirable.

One object of my invention is to provide a construction which overcomes this dilliculty and enables compara-tively wide work sheets, or standard large sized envelopes, to lee-introduced in unfolded condition into and be properly fed through the machine, and in which it is unnecessary to increase the length of the platen or the carriage, to attain the results.

Another object of my invention is to provide a novel construction and arrangement of parts, including a finger piece for turning the platen which may be moved from an expanded position for use to a compact position where it enables the machine to be enclosed within its carrying case.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the different views,

I have shown my invention in the present instance embodied in a Remington portable machine, but have illustrated only so much of said machine as is necessary to disclose my invention in its inclusion therein. The invention may be readily employed in such a. machine without material modification of its existing structural features except by the substitution of parts, as will hereinafter more clearly appear. It should be understood, however, that. the invention is not restricted to its employment in such machines.

In the Remington portable machine, as at present marketed, and as disclosed in the application of Joseph B. Holden Serial No. 533,945, filed February 3, 1922, a platen 8% inches long is employed, which enables a full written line to be produced on standard sized sheets, which do not exceed 8 inches in width. However, such machines do not enable a large sized standard envelope of 9g inches to be used in the machinewithout folding such envelope. By my present invention, a work sheet or envelope of 9% inches in width may be used without folding it, and without increasing the length of the platen or carriage, so that the machine may bel received within the same carrying case that is now in use, and without eliminating any of the advantages which accrue to the said machine as it is now employed.

-In the Remington portable machine, a carriage support 8 is mounted at its rear end for, fore-and-aft case shifting movement on parallel arms 9. These arms are fixed on a rock shaft 10, pivoted at its reduced ends 11 in the frame 12 of the machine. The upper ends of the arms 9 are pivoted at 13 to lugs 14 on the carriage support. 'lhe shiftable support carries a carriage comprising a main carriage bed 15 mounted in the usual manner on bearing rollers (comprising rollers 16) to travel along the. support 8. The carriage and assoc-iated parts remain substantially as they formerly were except at the right-hand end of the carriage. At. this end the usual car? riage end plate has substituted therefor a member, preferably formed as a combined end plate and bracket arm, designated as a Whole by the reference numeral 17, and shown detached and in detail in Fig. 6. This member is preferably made of sheet metal and comprises a foot piece 18-secured by screws 19 to the carriage bed 15. Projecting upwardly from this foot piece is a carriage end plate 20, preferably formed as shown, with all parts thereof arranged outside of lines coincident with the cylindrical surface of the platen, so as not to extend into the path of a Work sheet a that may overlap the right-hand end of the platen, as will be understood from a consideration of Figs. 3 and 4. Projecting outwardly and horizontally from the foot piece 18 for a considerable distance beyond the end plate 20, and beyond the right-hand end 21 of the carriage bed, is a bracket arm 22. Projecting upwardly from this arm 22 at the outer end thereof is a support or bracket arm provided with a central opening 24 concentric with the platen 25. This opening in the present instance is of slightly less diameter than the platen, and the Walls 26 thereof form a bearing, as will hereinafter appear.

The right-hand platen'head 27 is apertured at 28 (Fig. 6) to receivescrews 29 that are. threaded into the Wooden core 30 of the platen, and thus firmly secure the platen head to the platen. Extending outwardly from and preferably integral with the platen head, is a cylindrical extension 31 arranged concentrically With the platen, and preferably having a diameter about equal to that of the platen. This extension is provided With side openings 32 through which the operators fingers may pass to gain access to the finger piece or Wheel 33. The outer edge 34 of the extension constitutes an abutment which bears against the inner face of the bracket arm 23; the latter acting as a thrust bearing to prevent a longitudinal displacement of the platen to the right,

or to the left as the parts are viewed in Fig. 2. Y j

The platen head 27 as'usual, contains a central bore 35 into which extends a spline projection 36 fixed on the head. A spindle 37 extends through the bore 35 and projects at all times out beyond the right-hand endv of the platen. This spindle preferably ex tends throughout the length of the platen, and is seated at its left-hand end in a bearing carried by the left-hand end plate o`f the carriage., and forms a support for the platen at such end. The spindle 37 is provided with a s-pline groove 38 that receives the spline projections 36; causing the spindle and platen to turn together but permitting a limited longitudinal movement of the spindle relatively to the platen. A pin 39 is fastened to the spindle and projects into the spline groove 38 at one end thereof. This pin eoacts with the spline projections 36 on the platen head to limit the outward movement of the spindle, as shown in Fig. 2.

Referring more particularly to Figs. 1 and 2, it will be seen that the finger wheel 33 in the present instance is constructed of two rigidly united parts` One part is a hard rubber grip 40, which has a metal bushing 41 fixedly secured thereto; corrugations 42 on the periphery of the bushing aiding in securing the bushing and grip to turn together. One end of the bushing is provided with an integral diskor flange 43 that has a central bore to receive the spindle 37. A spline projection 44 extends from one side of this bore into the spline groove 38, to connect the finger Wheel and spindle to turn together but permit the finger Wheel to receive a sliding movement on the spindle. A screw 45 is threaded into a tapped opening in the right-hand end of the spindle, so as to act as a stop to limit the outward movement of the finger wheel on the spindle. It will be observed that the diameter of the disk 43 corresponds to the diameter of the grip 40, and that both diameters correspond to the inner diameter of the cylindrical extension 31, and to the bearing opening 24 in the bracket arm 23. It Will be seen, moreover, that the finger wheel 33, Whether in the contracted position shown in full lilies in Fig. 1, or in the expanded posi-l tion indicated in Fig. 2, receives a support inthe bearing in the bracket arm 23, and thus supports the platen at this end thereof. In the expanded position the periphery of the metal disk 43 of the finger Wheel is seated in the bearing opening in the bracket arm 23 and provides an effective support and bearing for the platen at this time when the platen and the machine are conditioned for use. I prefer to employ a cap or screw 46 that vis received in a tapped opening in the bore of the bushing 41 of the finger Wheel, thus closing the outer end of said riage support 8. p In the bore. The inner end of the screw i6-also constitutes a contact which coacts with the screw '45, to cause the spindle 37 to be moved in after the fin er wheel` recelves a rellminary limited te escoping movement into thev received and adapted to move longitudi nall and to turn in a bearing member 47 in t e left-hand end plate 48 of the carriage in the usual manner. As is vusual (in the Remington portable machine, and as is disclosed in the application of Joseph B. Holdemserial No. 547,128, filed March 27, 1922, a member 49 is ivoted at 50 on the left-hand end plate o the carriage.- This member 49 is provided with a locking finger 51 that is received in a transverse slot 52 in the bearing member 47, and is ada tedt extend across the bearing opening t erein, as shown in Fig. '5. The member 49 is also provided with ade ending'locking member or projection 53, a apted to be received 1n a recess 54 (see Fig. 1) of a sprin locking latch 55, secured at one end to t e carresent instance this locking latch is secure to the carriage support 8 about of an inch further to the left than ordinarily.

The member 49 also has anarm 56 which carries a laterally bent finger piece 57, located in the rear of a carriage releasing arm 58 which terminates in a finger piece 59. This arm 58 is connected to a supporting plate 60, mounted on the carriage pivots 61 and carrying a feed rack 62, whicnormally engages the lowermost feed dog 63. to restrain the power driven carriage gainst movement in the direction of its eed.

It will be understood that the finger 51 normally extends into the path of the lefthand end of the spindle 37, as shown in Fig. 5', and prevents a longitudinal displacement of the spindle to the left. This prevents the finger wheel from being moved to the limit of lts movement within the cylindrical member 31, and prevents it from being moved in far enough to clear one of the side walls 64 of the cover of the carrying case for the v machine. Therefore, lin this condition, the

cover is prevented from being closed to enclosed the machine.

In order to condition the machine for enclosure within its carrying case, the operator, aside from contacting the type bars in the usual manner, presses forward on the finger piece 57, and then moves the finger wheel 33 to the limit of its movement to the left. The effect of actuating the finger piece 57 is to move the locking finger 51 out of the path of the spindle 37, move the locking projection 53 down into effective position and move' the carriage releasing arm 58 forward, thereby releasing the feed rack operator on the finger piece 5.7, the nger wheel 33 is moved in to the full line Fig. 1 position, as ex lained. 1 The first part of the movement o -This prevents a return movementl of the member 49 to normal position under the 62 tofreethecarriage. While the l*parts are thus maintained by'pressure exerted b the' the wheel 33 slides it on the spindle 37 until the ca screw 46 reaches' action of its spring 65, and thereby locks the 'i projection53 in efi'ective position and locks the feed rack free from the normally engaged feed dog. The carriage is then moved from its off-centered position in either direction, to a substantiallyY centered position in its line of travel, and when a substantially centered position is reached, the members 53 and 55 of `the center lock automatically coact to lock the carriage against travel in either direction from said centered posii tion. With the machine thus conditioned the cover may be closed and the machine enclosed within its carrying case.

To re-condition the machine for use it is .t merely necessary after removing the cover toexpand the type bars in the usual manner,- and then move the finger wheel 33- from the full to the dotted line position in Fig. 1.

The finger openings 32 in the cylindrical extension, which surrounds the wheel 33 at this time, gives ready access to the wheel for this purpose.l The first part of this outward movement of the finger wheel to the position of use, is effected independently of the spindle 37, and vuntil the bottom wall 66 in the bushing reaches the overlapping head of the screw 45, when the spindle will be picked up and moved tothe right with the fin er wheel to the Fig. v2 position. The eect of this is to withdraw the yleft-handend portion of the spindle out of the path of the finger 51. The spring 65 will then return the member 49 to the normal position shown in -Fi 5, thereby rendering the center lock ine ective, and returning the carriage to the restraint of its escapement mechanism by permitting the feed rack to return to normal tion of its springs 6 While I prefer to employ the finger wheel 33 in combination with the other features disclosed to control the center lock and carriage release, yet, from certain aspects 'of my invention, it is immaterial whether the finger wheel be employed in such a combination.

It will be understood that in the specific construction as disclosed in the present instance, -when a 9% inch envelope or work sheet a is in the machine and overlaps the right-hand end of the platen to the capacity position under the acof the machine, as shown in Fig. 4, the finger wheel when imposition for use extends outside of the arm 23 and beyond the range of the envelope or work sheet, where the finger wheel may be used effectively without interference from or interference with the envelol'ievor work sheet.

It will be seen, moreover, that the inner face of the bracket arm 23 acts as a side edge gage by which a. large envelope or work sheet a, that overlaps the righthand end of the platen may be properly' intnoduced, and not be interfered with in its feed movement through the machine between the paper apron G8 and the platen 25:

Various changes may be made 1n the con struct-ion shown and described. and parts thereof may be employed without others without departing from my invention as it is defined in the accompanyingl claims.
