The box-like cover in which a so-called portable typewriter is enclosed is separate from the same use, and one can imagine easily how troublesome such an arrangement may be to anyone who has to work in the train or at the hotel or on a desk.

It should also be considered that in the future the typewriter of the portable type will not merely be a machine especially designed for travellers but also, by virtue of its compactness and low cost, it will constitute a popular instrument that,

`provided it is at least designed rationally, will nd its place at home just the same as any other Vmodern machine that contributes to comfortablelness and agreeableness.

Here again, only a low typewriter that cannot be operated if not coupled with its cover win be suitable, since it can be arranged most easily in .a piece of furniture, e; g. in the drawer of a table,

Figure 3 is also a side elevational view showing the typewriter as it is taken out of its case or placed back into it.

Figure 4 is a plan view of the typewriter carrying handle.

Figure 5 is a side View of the typewriter in its working position.

Figure 6 shows details of the base-plate lid in its closed position.

Figure 7 is a vertical sectional view of the baseplate and the lid thereof in the open position of the latter.

Figure 8 is a side elevational View of the completely open typewriter as carried by a pair of side parallelograms.

' Figures 9 and 10 are fragmentary front elevational views of the typewriter in its working and closed positions respectively, the case being shown in sectional view; in this embodiment ,the enclosing is obtained with the aid of parallelograms.

Figures 1.1 vand 12 are views similar to Figs.

4 Claims. (Cl. 197-186) 9 and l0 and relate to a modication in which the closing is obtained simply by hand operation.

Figure 13 is a sectional view taken on line B--B in Fig. 3 and shows the connection of the baseplate with a side-plate and the case.

Fig. 1 shows that while in a highly depressed typewriter the space is still available vertically to accommodate the printing keyboard in its inoperative position, it would be impossible to depress the longer key levers completely withoutttheir being stopped by the typewriter basepla e.

On the other hand, it has been mentioned precedingly that a typewriter which could not be operated unless it has its cover attached thereto would afford considerable conveniences in its use. Up to the present it has been found suiicient to secure the typewriter on the bottom of a case,

which bottom most frequently provides the baseplate that carries the typewriter, and to cap the latter with a simple enclosing cover which becomes wholly useless and highly cumbrous in worktime.

According to this invention, the machine is mounted immovably on a part 21 of the case which provides the bottom or baseplate thereof. Said bottom 21 carries a movable lid 28 (Figs. 1, 5, 6, '1, 9) which is shut when the typewriter is not in use and which opens automatically when any one of the keys is depressed.

It will be seen in Fig. 1 that when lid 28 is open printing can be performed normally, the bars Sbeing able to operate unhindered.

The typewriter secured on its base-plate 21 is enclosed in a cover or case 19 which protects the same from shocks and dust. Said case has less breadth than the base plate, so that a bearing margin is left between the same and the edge of the base-plate all around the typewriter which is useful for seating the latter in both its enclosed and its operative positions. Fig, 13 shows the cover or case 19, the base-plate 21, and the left side-plate 29 on which the eye |66 serves for the pivoting of the links |61, |62 of the parallelogram |56, |51, |6I, |62 by means of pin |63 (Figs. 2, 5, 8). If the typewriter were enclosed in its base-plate and case it could not be operated as described hereinbefore unless the lid 28 were open (Fig. 7), since the key levers S tend to project below the base-plate. Consequently, for enabling said lid 28 to open, space must bc provided for the same further below; such space can be secured with the aid of retractable legs or of any other suitable props.

However, since portable typewriters must be provided with a cover, it is congruous to use the latter both for enclosing the typewriter after its use and for transporting it as well as for supporting it .when inuse, whereby a twofold advantage 'is secured, in that on one. hand the space necessary for the opening of the lid is provided and on the other hand it is not possible to operate the typewriter unless its cover is attached thereto.

This leads to making the lid unremosabl'e from4 the typewriter.

The closing and openingbi the.case can ,be performed in two ways, viz.: lst, by means ci a pair of deformable parallelograms, 2nd, by simply overturning the typewriter by hand upon or into its case.

Both ci these arrangements will be described.

1st (Figs. 2, 3, 5, 8). The typewriter being assembled with its baseplate 21 and casingia.

its position is secured during the time it is taken intocr out of the -case 52 by the pair of parole lelog-rams fulcro-med at les-fand |55 on saidcase and each oil which comprises a pair ci arms |51 coupled with .each otherby teeth 4compelling them to move by-,equal amounts in 'reverse directions and a pair of linksv |6l, |62 vpivoted atene end on said 'arms.|61,a.|6 andat the otherend at@ |63 .on the base-plate 21.

As shownrin Fig. 2 the typewriter is-enclosed in; its case. Thearmsof the parallelogram have opened andthe AVspring |60, tensioned over the pivots i@ and |55,A tends to lclose the parallelogram again, whereby the case is compelled to remainl on the piece of furniture forfthe'time the typewriter is being opened...

. By takingfholda of ,theztypewrit'er at .either end of. itsibase-plate 2:1 and pulling; it upv same will befraised clear. ofritsycase: |52 (Fig. 3)"and'this movement, assisted by the'tension'of spring |60, willproceed until the lstops |561. and: |511, by coming into: engagement with each other, put air-end to it (Fig. 8).v Atthat moment, while the two side f parallelograms Vare 'Y sustaining the typewriterin itsraisedposition', same willbe overturned about-.|63 as--shownby the arrow |64, whereafter, by a. slight pressure exerted there` upon, it will be sunk"` home-'vinto itsfoperating positionv (Figzf5l'.

Upon the work being nished, it is only necessary to proceed once again as described, whereafter, by upsetting the typewriter, the system will be again such as it is shownin Fig..2.v

The advantages and; conveniences in use brought about by such a combination will be appreciated easily.

Figs. 7, 9, 10, 11 and l2 show how the typewriter as ay whole is supported on the base-plate. Aplastic strip is secured inside the case at the edge thereof and provides the seat the typewriter is to rest ongwhether enclosed or displayed. Of course, saidstrip could be replaced by a strip of another suitable material.

2nd (Figs. 11 and'12). The process of taking thetypewriterinto. and out of its case may simply consist in taking-hold of the case or the typewriter and bringing them into relation with each other as shown in Fig. 11 where the typewriter is open and in use or in Fig. 12 where the typewriter isxenclosed in itsrcase.

In this type ofenclosing the upper-edgev |521 stands higher than-.the :strip `ofplastic material |65, so that va retaining angeisleft'for the typewriter, which preventsthe s latter from sliding sidewayson its cover inthe-,course of its operation.

The lid 28 shown in detail is Figs. 1, 6 and 'Tis as broad as necessary for.. the passagev of all the levers in the keyboard;- It is 'hinged at--28l to the base plate .21'. Itstravel is limited by-"a member |61pivoted on lid'28'.' Said member |61 is formed with two bevel notches; Apin |68 on the base-plate 21`is;received1 in the upper -notch in member |61' when thelidis open and in the lower notch when the li'dis closed.' A spring-|69 anchored to the lug on member |61"urges'the latter intopermanentl engagement withVV pin |68. When the lid is closed it remains in the'position in which it is secured by the ramp onY the lower notch; in order to-open said lid-it isonlyneces sary to press same downwards, whereby the ramp on the lower notch'is caused tov` drive member |61 aside to the left, whereafter1the-same-will snap back to the right while the pin |68 Yslips on the ramp in the upper notch inwhose bottom it comes to rest, thus'keeping-'thelidopen; the upper notch ends in a hook adapted to limit the travel in opening.

|53 designates buttonsmade of plasticmaterial and intended tox the typewriterfon the desk during its operation by their adhesion.

Figs. 3 vand 4 show a handlefforA carryingv the typewriter. Said handle, located at the front, is received in a recess |1| provided-inthe-base plate in the spacev left free 'by'A the keyboard in the enclosed position of the typewriter;

Said handle ilfis mounted-on aA pair of strips |13, |14'. journaled on |15 and each of which is formed or provided with aboss= 131; |141 respectively. When the typewriter is 'to be carried Vthe handle is pulled out of itsf-recessll, whereafter it is swung on the arc |16 (Fig.V 3). 11i-'order to restore thevhandlesame `is pushedfbackintothe position shown in chainlines;l where'it remains retained by the pressure of the pair' of bosses |131, |161 Y against-"the vside wallsV oirecess l1 The above-describedI arrangements are men*- tioned by way of example only, since theshapes,
