JOHN H. BARR, OF NZEW-YORK, N. Y., ASSIGNOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, YORK, A CORPORATION v OF NEW YORI K.

TYPEWRITING MACHINE.

Application filed May 8,

To'aZZ whom it may concern:

Be .it known that I, JOHN H. BARR, citizen of the United States, and resident of the borough of Manhattan, citv of New York,

in the county of New York and State of larly to so-called portablemachines, wherein it is desirable to make the parts as light in weight as .is consistent with the rigidity and strength required to withstand the strains to which the machine may be subjected in use and during transportation,

One of the main objects of my invention is to provide a simple, strong, light and effective frame for the machine, which aids materially in accomplishing the above men'- tioned results, and yet presents a pleasing outline and appearance; all unsightly parts being covered.

A further object of my invention is to provide a machine frame of the character specified which comprises a double frame or two sections detachably but fixedly united, and in which all of the working parts of the machine may be supported by the inner "frame or section, and the latter, together with said parts, may then be introduced as a single unit into the outer enclosing frame or section, and. be enclosed thereby and the sections firmly secured together.

This enables the working parts of the machine to be assembled and mounted on the inner frame with facility, since the various parts of the machine are readily accessible wh n it is not enclosed in the outer frame. Moreover, there is no danger of marring the finish of the outer frame since it is unnecessary to handl'e it until the machine is completely assembled and adjusted and ready to be introduced as a unit into the outer frame and thus delivered as a marketable machine.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and par- 1922. Serial No. 559,119.

It should be understood howevm', that the invention may be embodied in other styles of machines.

I have represented in the drawings only so much of the Remington portable machine as is necessary to arrive at an understanding of my invention in its embodiment therein.

The frame of the machine comprises, in the main, what may be referred to as two members or sections, one of which is shown in detail in Fig. 4, and which may be termed the inner frame or section which supports all of the working parts of the machine, as will hereinafter appear. The other member may be called the outer secobscuring a view. of the, inner tion or frame, and. is shown in detail in Fig. 1. ,This outer frame encloses the inner' frame and is detachably fixed thereto, frame and many of the working parts of the machine, and impartin a neat and finished appearance to the'ma'c ine as a'whole, A

top plate, shown in detail in Figs. Sand 6,

surmounts the outer and inner frames and is detachably secured in place thereon.

The. inner frame is designated as a whole by the reference numeral 1, and "comprises two sheet metal side plates 2, and a hollow sheet metal cross bar, 3 fixed at its ends on studs that project from plates 4, which in turn are secured at 5 to the side plates 2.-

The side plates 2 may be further connected by a front comb plate 6, secured by screws ,7 to inwardly extending ears 8 which project from the side plates2. An angular sheet metal keeper bar 5 may also be employed to connect the side plates; the upper screws 7 being employed to connect the keeper bar therewith. Forming a further firm connec tion between the side plates 2 is a casting,

designated as a whole by the reference numeral 9. This casting isformed with two bracket arms 10 each of which terminates in a foot piece 11. Each foot piece has an outwardly extending horizontally disposed rib or lug 12 that is seated in a horizontal milled slot;13 in the companion side plate 2, of the frame. The outer contact face 14 of each foot piece bears against a side plate 2, and the casting is firmly secured to the side plates by headed screws 15 received at their" threaded ends in the foot pieces 11 of the brackets '10. This casting includes a slotted type bar segment 16-and an integral slotted segment 17 for the sub-levers of the type actions. In Fig. 4 I have shown onlyi a few of the slots 18 and 19 in the two segments 16 and 17 respectively; the remaining slots being omitted to simplify the showing. It will be understood that aside from other connections, the casting 9 constitutes a firm and rigid connection between the side plates .2 near the rear of the frame, whereas'the cross bar 3 forms a further rigid connection between the side plates near the front of the frame. i

Various openings are provided in the s de plates 2, as shown, for forming bearings for different working parts of the machine, for mounting pivot pins on the side plates, for affordingpassage of the stems of. connecting screws through the plates, and for various other purposes, but it willbe unnecessary to describe these openings in detail or the pur pose of each. I

.The lower edge of each side plate 2 is formed with feet 20 by which they may receive a support on the outer frame, as will hereinafter appear. Projecting rearwardly from each side plate 2, near the lower portion thereof, is a horizontally disposed extension 21 which, with the rear edge 22 of the main body port-ion of the plate, forms substantially a right angle, so as to provide an .L-shaped recess in which the carriage support and carriage are received, and through which the carriage may travel, as will be understood. from an inspecti'on of Fig. 7. a

From a consideration of thelast mentioned figureit will be understoodthat every working part of the machine is mounted on or supported by the inner frame; suchparts being disclosed and described in detail in many of the hereinbefore mentioned patents and pending applications. Thus the collapsin'g type bars and type actions are disclosed i the Smith Patent N0.-1,342,513; the calriage, carriage mounting and case shifting mechanism in the llolrlen Patent No. 1,386,256; the escape-ment mechanism in the Seibapplication Sr. No. 529,415 and in the Holden application Sr. No. 558,951; the ribbon mechanism-in the Holden Patent No.

1397.166; the, back spacing mechanism in theBridgwater Patent No. 1,388,164; and

the line lock and margin stop mechanism is similar in many respects to the construction disclosed in the Holden Patent No. 1,381,994.

It is considered unnecessary therefore to describe in detail all of these-constructions, or so much of them as, are shown in Fig. 7, it being deemed sufficient to refer briefly to these various constructions and to indicate that they are carried by the inner frame 1, as shown in Fig. 7. This is especially true since such features are embodied in the Remington portable machine.

The key controlled type bars 23 are mounted in the slots 18 in the segment .16, whereas the sub-levers 24 are mounted in the slots 19 in the segment 17. The key levers 25 are pivoted at their rear ends on the pivot rod 26 supported by a guide comb 27 fixed to fore explained. The carriage support is pivoted on two upright'parallel arms 34 which project from a rock shaft 35, said shaft being mounted at its reduced ends in openings 36 (see Fig. 4) in the side plates 2 of the frame. The carriage support 28 is fixed to two sheet metal. plates 37 tlIl'iUlgt-Kl at opposite sides of the machine near the plates 2 and which,

with the carriage support, constitutes the case shift frame on which the carriage is supported for bodily movement therewith fore and aft of the machine. The forward end of each plate 37 is pivoted, as at 38, to a depending link 39, pivoted at its upper end on a pivot pin 40 that projects inwardly from the associated side plate 2 of the frame.

- In this manner thecase shift frame is supported at its forward end by the parallel links 39 and is supported at its rear end by the parallel arms 34.

Not only is the carriage shiftable with the case shift frame, but among other devices that are also shiftable with said frame are the feed rack 41, the margin and line-lock stops 42, the dog rocker 43, the universal bar 44, the frame to which the universal bar is connected, the ribbon vibrator 46, its actuating arm 46 the ribbon spools 47, the ribbon feed mechanism including the ratchet wheel 48, the ribbon feed pawl 49, its actuating arm 50, the actuating arm 51 for the dog rocker, the rack 52 for the back spacer, and the back spacer actuating rod 53.

The case shift frame may be shifted by any suitable means, those shown comprising a shifting lever 54 to which a link 55 is connected. The upper end of said link is pivoted to a bell crank lever 56, pivoted at 57 (see Fig. 4) on a stud projecting from the left-hand side plate 2 of the frame, and held in place thereon by a screw 58. A depending arm 59 on its bell crank lever co-acts with the projection on the shift frame to shift it rearwardly to the upper case position. position by asliift lock key 60 that controls a shift lock member 60 mounted on the front of the comb plate 6.

The space key 61 has its supporting levers 61 f-ulcrumedon the comb platefi and ex tending rearwardly and down therefrom and connecting at their lower ends with a squared crossbar 62. This bar carries an arm 63 operatively connected with a link 64 pivoted at its lower end to an actuating arm which forms part of the dog rocker.

It will be seen, therefore, thatevery working part of the machine is carried by the inner frame, and that the construction is such that all of said parts may be assembled,

mounted in place, and adjusted in said frame while it is detached from the outer frame. The inner frame with the parts mounted thereon may then be introduced into the outer frame as a single unit without dismantling any part of the machine, and without having had occasion to handle or mar the outer frame until the inner frame with the working parts thereon, is to be placed in position therein and the machine as a whole is ready to be delivered as a finished product.

The outer frame is preferably made of thin sheet metal such as steel and is very The parts may be locked in shifted light since the strain on the machine is borne in the main by the inner frame. The main purpose of the outer frame is to cover many of the working parts and the unfinished inner frame, and impart to the machine a finished appearance and outline. Although the outer frame is light in weight, it adds, nevertheless, as a strengthening factor to the machine as a whole when secured in place with the top plate added. These parts tend to strengthen and render more rigid the inner frame, and the machine as a whole, as will hereinafter appear. The outer frame, which is shown in detail in Fig. 1 and designated as a'whole by the reference numeral 65, is made of two separate members welded together along the base at both sides and at the front, to form in effect one part. The lower member is formed from a single piece of metal of rectangular formation, as viewed from above, with an inwardly directed flange 66 joined to an upwardly extending surrounding wall 67. ach front, back and side wall of this member is therefore angular, or substantially L-shaped in cross section. The inwardly extending flange 66is apertured at its four corners to receive rubber feet 68, as fully disclosed in the hereinbefore mentioned application Sr. No. 469,458, and by which the machine is supported on its base board. The other member of the frame section is formed from a continuous piece of sheet metal with a front cross piece or wall 69 and side walls 70- The body port-ion of each side wall has a rearwardly extending portion 70 near its lower edge corresponding substantially to the projections 21 on the inner frame and, like the latter, forming an L-shaped or angular recess through which the carriage may travel. Beginning at the top edge 70*, and at or about the point where the comb plate 6 of the inner frame issituated when the parts are assembled, each side plate 70 slopes downwardly and forwardly at 71 to the front wall 69. An inte ral, inwardly turned flange, beading or rib 72 is formed on each inclined edge and continues along the upper edge of the wall 69. This flange gives a finish to the frame and strengthens and renders it more rigid. In order that the side walls of the outer frame may bear against the outer sides of the plates 2 of the inner frame at the points where the two frames are secured together, I prefer to form integral, inwardly extending bearing lugs'73 and 74 on the side walls 70 and 67, respectively, of the outer frame members, thus maintaining the side Walls of the inner and outer frame sections spaced apart except at the points where they are rigidly connected together, as indicated in Fig. 2.

The flange 66. where it extends across the machine at the front thereof, carries a sheet metal bracket 75, fixed thereto at 76. This the type bars.

bracket carries two felt pads 77 on the arms thereof, said pads co-acting with ,the space key 61 and with inwardly turned bracket arms 7 8 (see Fig. 7) to limitthe movement of the s ace key in both directions.

The eet 20 of the inner frame are supported on the side members of the flange 66 when the inner frame is introduced in position in the outer frame. Headed screws pass through openings 79, 80 and 81 m the sides of the outer frame and secure the two frame sections together. The screws WhlCh pass through the openings 81 also extend through registering openings 81 in the slde plates 2 of the inner frame, and are received in tapped openings in a crossbar 82. The screws which pass into the openings T9 are received in tapped openings 83 in the plates 2, Whereas the screws 84 (see Fig. 2) which pass throughthe openings 80, also pass through registering openings 85 in the plates 2 and are threaded in the tapped openings in depending lugs 86 on the top plate 87. These lugs are arranged between and support the plates 2 against inward movement. In this manner not only are the inner and outer frames firmly secured together, but the top plate 87 is detachably secured on the machine, thereby materially strengthening and rendering it more rigid.

The top plate may be of sheet metal but I prefer to make it of cast aluminum with depending strengthening ribs 88 formed thereon and a rearwardly and downwardly inclined curved portion.89 which may, if desired, be sheathed with a felt pad (not shown) to form a type rest for the ends of The top plate is also provided with a downwardly and forwardly inclined flange or apron 90 that aids in obscuring the parts of the machine.

The machine when complete presents a'- neat and finished appearance with: graceful outlines, and many of the working parts and the inner frame are covered by the outer frame and top plate.
