" by a keyI operated lthe case cover removed `Jarbidge, inthe county of Elko and State'of Nevada, havejinvented a new Noiseless Case for Noisy Machines.' of which l the following is aspecification.'V i' My invention' relates to 'the' 'absolute' rechi'nes as computing machines and typention 1s thatI remove the noisy medium, r',from'around,the machine by incasing 1t a suitable case, having means/for operati'ng the inclosed machine fromA without, and

when closed, toa vacuum chamber which removes the air. In this way I retain all the advantages of the present' high standard computing machines and typewriters,J but absolutely. remove all noise, such as' the impact .oftthe keys or :the noise caused by any '.dther noise making movements connected' with :the inclosedpmachine. 1 attain these "objects by use of a vacuum chamber and the mechanism illustrated in. the accom-y panying drawing, which shows vthe adaptation for' typewriters, in which'- Figure 1 is a plan of the vacuum case with sary parts of a typewriter. Fig. is an enlarged section taken through A-A, Fg. 1.

Fig. '3. is a front elevation of the case with coverin place. There .is also shown at the right hand side, a section taken through Fig. L.Lis an enlarged section taken through the vacuum `two way valve shown at C of Fig. 3.. Fig. 5-is a side elevation and sections combined of the case and necessary parts of a typewriter. The

section of thecase is taken through D-D of Fig. l1, except A hinge which are taken through Gr-G and 143-.- 4 respectively. .Fig 6l is a side eleva- 'tion of an auxiliary plate used for operating typewriters which are run by electricity.

ySimilar letters refer tosimilar parts throughjthe several views.

To explain the operation of the machine 'we will assume that the case is closed and that vthe operator wishesto open it. He presses the key marked f Case release, Fig. l. This raisesthe wedge a, see section Fig.

i .3, through the slot b in the latch c which presses bac the spring d of this latch.

The essential` novelty of my linvalve connect the case,`

showing the neces.

the release mechanism and vcarriage at b and to the bar m at y.

below the valve l1., or f, which is stronger than the spring above,l or g, quickly shoves thebalaxiced valve h'up till it is stopped by the projecting ring 7:. This shutsoff the vacuum chamber opening and opens the interior of the case to the atmosphere through Wb, the air coming in, in the direction of theA arrows, as shown. The vacuum -being broken in thecase, the springs in the hinges shown at n, Fig. 5, raise the top of the case to the -position shown by the broken lines atV p, Fig. 5. To close the case the operator presses thekey marked Case lock, Fig. l,

which operates a valve at the base of the hinged'cylinder q, Fig. 5, thus connecting" `the, .baseof the cylinder with the vacuum chamber 'through the pipe 7', Figs. 5 and 1,

which causes the piston to suclrdown due to joint around the rubber gasket s around the edge of the case. The bar e is alwayslocked by the latch c laii'ter the top of the case moves away far enough so the spring f cannot depress the weaker spring g through the valve 71.. Having'the case closed and 'wishing to shift the carriage at the'cnd of a line, the

operator presses the bar marked Carriage shiftfiFig. 1, which operates the little two way valve shown at C, Fig. 3, see detail Fig. 4:, and connects the end of the cylinder u with the vacuum chamber through the pipe r. The. cylinder u is always connected to the atmosphere by the opening fu, Fig. 3, and

the atmospheric pressure drives `the piston A w', Fig. 1, to the left ,which motion is communicated. to the piston fw, through the bar a', which in turn communicates an opposite motion to the carriage of the typewriter through the flexible cable. e which runs around the pulleys a and is attached to lthe Q leasing the carriage shift key the valve C connects the end of the cylinder u with the atmosphere and the air pressure being equalized the carriage performs its usual motion to the left in spacing. .lt is easily possible to construct the valve C so that it will remain connected with the vacuum chamber until the carriage has reached the end of its travel to the right, but this might cause the operatorto Write -While the .car-

. cushions upon nage was moving to the right and possibly throw the keys-out of alinement, so it 'was thought best to compel the operator to hold:

do'wn the carriage.l shift until the carriage had completedits travel to the right.

F rom Fig. 5 it will be lseen thatv the case touchesthe inclosed machine in the rubber which the typewriter g; Where the keys communicate motion, or lo, and Where ,the platen" turning-bar g passes into the platen. llhe universal joint at e"is of strong rubber, Fig. l, the key c, Fig. 5, communicates motion to the typeivrite'r key through the rubber cushion e, so no vibra-tion can -be transmitted to the -case from the machine.

.In Fig. 5, F is an adjustable plate having1 at its ltoppart the spring hinge and spring n for raising the case cover. The adjustment is made by placing the cover on the case properand connecting With the vacuum chamber. 'The pressure of the atmosphere on the gasket s ygives the proper fit, after which the lock nuts p arel securely screwed up. The stud bolts as-shoivn are part of 5 'trically operated kind, the gasketed plate the case.

Incase the typewritery is one of the elec shownv in Fig.,6 is4 screWedover the holes inthe case, thus making an air tight joint.

The Wires'are pulled through the key holes-f There is also a gasketedplate for the bottom as shown ata Fig. 5..-

On the frontof the case is a gasketed plate inthe shape of a segment, Fig. 3, held to the case by thumb screws.

pose of this plateis to ena-ble the .to get at the typebars for cleaning.

To turn the platen Whenthe case 1s. closed,

operator there is provided the auxiliary Wheel c.

of the feather shown' at Fig. 1,'Which turns the( platen through the joint e by means CZ Fig. 2, extendn strong rubber universal ing on the shaftg raised feather engages a slot in the platen rather loosely, so the platen is free to slide back andforth, along the said bar 'orshaft g. .'The use 'of the universal joint is to permit thecarriage to move vertically when r the shift key for capitals is used.

there is provided the glass cover l, lined or edged With metal 2X for strength. i
