Similar reference characters refer to similar parts throughout the several views of the drawing.

This typewriter case. is of a. universal type which may be used with any make of portable typewriter and is provided with mechanism to securely connect any. typewriter to the case after making one simple adjustment-in the connecting mechanism, as will be pointed out'hereinafter. In general, the metal connecting mechanism includes a clamping plate, generally indicated at I2, which may be moved toward and from the front wall 14 of the base 10 of the case by moving lever l6 downwardly and upwardly. Plate I2 is parallel to the rear of the typewriter framework and is so adjusted with respect to the back of a typewriter that when lever l6 ismoved downwardly into locked position, as shown in Figure 5, the typewriter is clamped between clamping plate [2 (Figure l) and the rear surface of plate 58. Lever I6 is provided with a tongue Ilia which engages the framework on the front of the typewriter and holds it down in engagement with base It), all as will be fully described hereinafter.

In detail, referring to Figure l, the case includes base in and a cover, generally indicated at IS. The side walls of the base In are low to permit a typewriter to be used while it is mounted on the base. Cover l8 has side walls 2. of sufficient depth to accommodate. the height of any portable typewriter and is preferably detachably connected to base In by detachable hinges (not shown).

All of the mechanism for connecting a typewriter to the case is mounted upon base 'lfl; Clamping plate I2 is parallel to and is mounted for movement toward and from front wall I4. This plate includes a forwardly-extending por-'- tion [2a (Figure 2) having a longitudinal slot 22 therein. Portion l2a of clamping plate l2 is adjustably connected to a link 24 which also has a longitudinal slot 28 therein. The forward end of link 24 extends through a raised portion 28a of a bracket, generally indicated at 30. Bracket 30 is connected to the bottom 32 of base It] by means of

rivets

34 and 36.

Longitudinal slots

26 and 22 are aligned with respect to each other and are utilized in mounting link 24 and portion 12a on a guide 38 (Figures 9 and 10) which includes a portion 38a extending upwardly through

slots

22 and 26. Guide 38 is connected to the bottom 32 of base In by means of a rivet, generally'indicated at 40 (Figure 9), the head 40a of which extends over link 24. Thus, guide 38 and bracket 30 serve to guide link 24 and portion He or" clamping plate l2 as they are moved toward and from the front wall I4 of base [0.

Slots

22 and 26 also permit clamping plate [2 to be adjusted toward and from front wall Hi to accommodate typewriters of different sizes. To lock link 24 to portion IZa after an adjustment is made, the under surface of link 24 has transverse teeth 42 (Figure 10) formed thereon which engage transverse teeth 44 on theforward end of portion I2a of clamping plate I2. A screw 46 passing through slot 26 and threading into portion l2a (Figure 2) acts through its head to clamp link 24 to portion I2a and thus hold teeth 42 in engagement with teeth 44.. When it is desired to adjust link 24 with respect to clamping plate I2, screw I2a is loosened, teeth 42 and.

44 become disengaged, and at this time clamping plate I2 may be moved toward. or from link 25..

When clamping plate I2 is properly positioned, screw 46 is tightened, and from then on, clamping plate I2 moves as though itv were an integral portion of link 24.

Movement of clamping plate I2 toward and from front wall I4 is controlled by lever I6 (Figones. ]i, 4 and 5.1.. Lever I6 is operatively connected to. an actuating member, generally indicated at 50 (Figures 2, 3: and 6).. Actuatin member 50 includes. a. cam. portion 5001 which acts upon the forward end of link 24 tomove link 24 rearwardly and includes a raisedcam portion 50c which acts through lever 52 to move link 24 forwardly... Lever 52 is pivotally connected to bracket. 36 by means of a pivot pin 54 and is. pivotally connected to the forward end of link 24- by means of a pivot pin 56..

Actuating member 58' and. handle I6 are mounted on the case'by a supportim plate, generally indicated at 58. (Figures 2 and 4) which is. connected to forward wall I4 of base I; by means of rivets 6B: and. 621. The body of plate 5.8. isspaced' from and parallel to wall It. to form an enclosed space 50; within which actuating member a isv mounted. Actuatirrg member 58 is split. along its center portion (Figure 6) to form a section Silo. which. abuts against plate 53 (Figure 2) and a section 5022 which abuts against the rear surface of wall I;4.. lhe end portion 59c. of member 5.0 extends rsarwardly and abuts against the forward surface of supportin plate 58.. Sections 50d and 58b and end portion 5180 act as guides to: insure movement of member 55 in a vertical plane as. itmoves longitudinally of plate 58. Member 56 rests upon bottom 32 and is heldin position by lugs 6.4 and G6: stamped out of and extending-forwardly from plate. 59 (Figures 2 and. 4-).

The other end: portion 5.911 of member 5:] is angularly positioned with respect. to wall Hi to form a. cam surface so that. when, member 5.!) is moved; upwardly; as viewed. in Figure 2, it engages a lug: 2m extending upwardly from the forward end of link 2%. and moves link 25,, and thus. plate I52, away from wall I l. as viewed in Figure 2. Member 53 also includes, an angularlyshaped portion 596 which forms a. cam. surface 63 engaging the singularly-shaped forward end 52a of? lever 52. Thus,whenever member 5c is moved downwardly, as viewed in Figure 2, lever 52 is turned in a counterclockwise direction about pivot 54.and acts through; its pivotal connection Eli to link 24'. to. move clamping plate I2 toward wall: I4.

Lever l6, which. moves member 53 transversely of the case, is pivotally connected to plate 58 by headed pivot pin I9 (Figures 2. and: 7). A pin "Ill. mounted" on member 59 extends intoa cam slot I2 (Figures 4; Stand 7) cut in the lower end of lever. It. Cam slot 12' is so shaped that when lever l6 ismoved downwardly from. the position it occupies in Figure 4 to the position it occupies in Figure 5, the slot acts upon pin I13: to move actuating: member 50: to the left. Furthermore, when lever I6 is. moved: from the position it occupies in Figure 5 to theposition it-occupiesin 4 Figure 4, cam slot I2 acts upon pin I4 to move member 50 to the right, as viewed in Figure 4.

As pointed out hereinabove, tongue I6a of lever I6 prevents the front end of the typewriter from movingupwardly with respect v to base II) when the typewriter is locked to base I0. To accomplish this, tongue ISa is pressed downwardly into engagement with the upper surface of the forward portion of the frame of a typewriter diagrammatically indicated by the dotted lines 86 (Figure I1). To hold lever I6 in a locked position, it is provided with a detent 82 (Figures '7 and 11) which 'coacts with teeth 84 formed on and extending forwardly from one edge of a recess 86 formed in plate 58 (Figures 4 and 11). Lever- I6 is so shapedthat detent 82 is normally resiliently pressed into engagement with teeth- 84. Thus, whenever lever I6 is, pressed down: ward-1y, detent 82 ratchets over teeth 84. until tongue I6a engages the framework of the? typewriter. r

As lever I6 is being moved into engagement with the framework of the typewriter, clamping plate I2 is being moved forwardly to. clamp the typewriter against the forward surface of plate 58. To improve the frictional grip of plate I2- upon the rear surface of the typewriter it preferably provided with a rubber pad 90 secured to plate I2 in any suitable manner. In operation, screw 46 is loosened (Figures l and 2), and the; portable typewriter to be mounted on the case is placedon bottom 32 with its forward end in engagement with plate 58. Plate I2 is then moved forwardly until pad 90 is spaced a slight: distance from the rear surface of the typewriters framework. The typewriter is then removed and screw 46. tightened. At the time this adjustment is made, handle I6 is in a raised position, as shown inFigures 1 and 4.

Next, the typewriter is placed in the case with its forward end abutting against plate 5.8 (Figure l) and handle I6 is pressed, downwardly until portion I5a engages the upper surface of the front portion of the framework 8Ilof the. typewriter (Figure 1-1). During the downward movement of lever I6, plate I2 is moved forwardly so that it engages the rear surface, of the typewriter and presses it tightly against. plate 58. Because .of pad 90, the rear portion of the typewriter is securely connected to basev I6, and the forward portion of the typewriter is held in position by tongue I60. of lever It. When itis desired to remove the typewriter from the. case, the user presses forwardly on fingerpiece IBb (Figures 7 and 11) to disengage detent 8.2 from teeth '84. Lever I6 may then be raised from the position it occupies in Figure 5 to-the position it occupies: in Figure 4. This moves plate I-;2 rearwardly, freeing the typewriter so that it may be removed from the case.

It will thus become: clear that plate I2 may be adjusted: tosuit any typewriter, no matter What its length, and lever I6 is also so constructedthat it will. engage the top surfaceof the forward portion of the framework of. all; portable typewriters and can be locked. in that position. In this connection, it might be noted. that cam slot 1.2 (Figure 4) is so shaped that plate I2 (Figure 2) is in typewriter holding position by the time detent 82 reaches the uppermost tooth of teeth 84. Thus, regardless ofthe height of the front of a typewriter, the typewriter will be just as securely mounted when the detent engages the uppermost tooth as when it engages the bottom tooth..- It will; thus be seen. thatza thoroughly practical and efficient typewriter case has been disclosed which is adjustable to carry portable typewriters of all makes. Furthermore. the connecting mechanism is such that it may be readily and quickly operated to mount a typewriter on or detach it from the case. Accordingly, it will be seen that the several objects hereinabove mentioned, as well as many others, have been successfully accomplished.

As many possible embodiments may be made of the above invention, and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinabove set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
