" l' 'COMPACTIBLE mnwRIrrNG-MACHINE Application med July 2,- i917. serial No. 178,253.

To-aZZ whom t may con/0cm:

Be it known that I, STANLEY R. DE PUE, a citizenof the United States of America, and a resident of the city' ofv Washington, Districtof Columbia, have invented certain new and useful Im rovements in Compactible'Typewritingachines, ofwhich the followingis a full and clear specification.

The Object of this invention is to so construct the machine that it may be compacted for convenience in transportation and storage, as more fully'hereinafter set forth.

In the drawing is vrepresented a vertical, longitudinal, sectional view illustrating so much of a typewriting'machine as is neces-l to illustrate my present improvement. eferring vto the drawing annexed by numerals, 10 designates the mainv frame, on which are mounted injany suitable manner the key-bars 11, each key-bar being provided Sal vwith adepending ear 12 which is provided with a pin 13 in its lower end, which engages the radialslot 14 in arm 15 journaled on a rock shaft l'16 affixed to the lower edges of the side-bars of the frame# Each of the arms 15 is provided with an upstanding larm 17 which is connected by a rearwardly-- extendinv link 18l to the heel of the typebar 18 o the usual construction. The typebars are pivotally mounted in the usual manner in the type-bar Asegment 19. This manner of connecting 'the key-bars to theA type-bars is advantageous in that it enables the type-bar segment to be brought well forward vin the machine in order to provide space enough between the type-bar segment and the rear wall of the frame to receive the platen carriage and connected parts when the machine is compacted, as more Afully hereinafter set forth.

At each side of the main frame is pro- 4 vided a pair of vertical guide ribs 20 which are engaged by channeled legs 21 of a top plate or frame 22 which carries the-usual platen carriage 23. This frame or plate 22 is thus vmade vertically slidable, and it is held in its adjusted positions in'any suitable manner, vpreferably vby spring-actuated latches 24, one of which'is mounted in each of the legs 21 and'is adapted to engage notches 25 in the guide ribs 20, the en age-l ment ofthe latches with the notches eing preferably a frictional one, s o that the movable frame may be raised or lowered -by aplie behin 'plying a little effort thereto land also in order that, whether the frame be lifted or lowered, it will automatically lock at the desired height. The'lower notches 25 are so located that `when they are engaged by the latches, the rear portion of the movable frame together with the platen carriage will anism carried by the movable yframe will have been lowered to al point approximately on a level with 'the upper ends of the guides 20, thus compacting the machine to the eX- tent of movement of. the frame upon the guides. The foregoin construction is more ullyillustrated and,- escribed in my application filedvk herewith, serially numbered 178,252. j

Depending centrally in the type-bar segment isa universal bar 26 which is adapted to be centrally struck by a projection 27 on each of the type-bars. Pivotally mounted on the depending hanger 28 carried by the platen carriage supporting frame '22 is an escapement lever 29 which normally bears against the universalv bar 26 and controls the escapement wheelv 30 in the usual.manner, the shaft of this escapement wheel being supported from the frame 22 and being provided with a pinion- 31 which engages the feed-rack 32 on the carriage. The usual spring, not shown, is provided for moving the carria e, and any suitable ribbon-feeding and vi rating means, operable from the universal bar 26, may be mounted on the supplemental frame, so as to be vertically adjustable therewith. `It will be observed that all the carriage-feeding devices are mounted on the supplemental frame, so that Awhen this frameis dropped down into the lIt will be observed further that by pivotingthe rocking members 15 on an axis below the key-levers, `I am enabled to bring the the type segment while the mech Specification of Letters Patent. v i Patented Oct, 26, 1920.-

type-bars closer to thev key-levers and thus obtain desirable compactness in a verticall direction.

It will be understood that the case shift may be obtained either by shifting the supplemental frame up and down in addition to the shifting this frame receives in compacting and extending the machine, or the case shift may be obtained by vertically shifting the type-bar segment; I preferl the latter, as fully disclosed in my co-pendingapplication filed herewith.

It will be observed that by continuing the pull upwardly on the supplemental frame 22, this frame together with all the parts connected thereto may be entirely separated from the base-frame; the advantage in this is that it will give ready access to all the mechanisms carried by both the base-frame and the supplemental frame, to thereby greatly convenience the matter of cleaning and repairingA the parts.

The nature and scope of the invention having been thus indicated and its preerred embodiment having been specifically described, what is claimed as new is:

l. In a collapsible typewriter, a baseframe carrying the printing instrumentalities, a supplemental-frame carrying the platen carriage and escapement mechanism, and means whereby this supplemental-:trarne together with said escapement mechanism the combination of a base frame, a type seg,

and platencarriage may be, as an entirety, slidably separated from the base frame.

2. In a collapsible typewriting machine, the combination vof a base frame, a typel bar action mounted on the base frame, a universal bar mounted on the base frame and op-v erable by the type bars, a platen carriage, a carriage support, connections between said support and the base frame whereby said support 'may be shifted relatively to the base frame to place the carriage in a lower upright position at the rear of the type bar action to reduce the height of the machine when not in use, and carriage feeding mechanism operable by the universal bar and movable as an entirety with thecarriage and carriage support relatively to the universal bar 4to a lower position out of coi operative relation with the universal bar when the machine is collapsed.

3. In a collaps1ble typewriting machine,

mentl mounted on the base frame, type bars pivotally mounted on said segment, lrey` levers mountedon the base frame and operatively connected to actuate the type bars, a universal'bar supported on the type segment within the are of the segment and operable by the type bars, a platen carriage, a carriage support, .connections between said support and the base frame whereby said supportv may be shifted relatively to the base frame to place the carriage in a lower upright position at the rear of the type segment to reduce the height of the machine when not in use, and carriage feeding mech- Leaders anism operable by the universal bar and movable as a unit in its entirety with the carriage and support to a lower position out of coperative relation with the universal bar when the machine is collapsed.

4. In a collapsible typewriting machine, the combination of a base frame, a supplemental frame, sliding connections between said frames whereby the supplemental frame may be moved vertically up and down on the base frame to collapse and extend the machine, a vuniversal bar, a type bar action mounted on the base frame, a platen carriage mounted on the supplemental frame, and carriage-feeding mechanism operable by the universal bar and movable in its` entirety with the carriage and supplemental frame to a lower position out of cooperative relation with the universal bar,

5. In a collapsible typewriting machine, the combination of a base frame, a supplemental frame, sliding connections between said frames whereby the supplemental lframe may be moved vertically up and down on the base frame to collapse and extend the machine, a type bar action mounted on the base frame, a universal bar operable by the type bars and supported within the base frame independently of the supplemental frame, a platend carriage mounted on the supplemental frame to move therewith in a vertical plane at the rear of the type bars and universal bar, and carriage-feeding mechanism locatedbelow the carriage and mounted lto move in its entirety vertically 100 with the carriage and supplemental frame into and out of coperative relation with the universal bar. v

6. rIhe combination' with a base-frame carrying printing instrumentalities and an 105 upright universa bar, of a supplementalframe rectilinearly slidable to a point behind said universal bar for compactness, said supplemental-frame carrying a platen' carriage and a complete escapement mecha- 11C nism, the construction beingsuch that when the supplemental-frame is slid up to operative position the operating elements-.of the escapement mechanism will be -moved into position to be operated by the universal bar. 11E

7. Ina collapsible typewriter, a baseframe carr ing the type-bars and the. operating mec anism thereof, and a supplemental frame carrying the platen carriage and the carriage-feed mechanism, said sup- 12( plemental frame being vertically slidable upon the base-frame and readily detachable therefrom as`an entirety and by a vertical sliding action. l

8.' The combination of a base-trame car- 12! rying printing instrumentalities, including an. upright segment carrying a depending universal bar, a supplementalframe carrying the complete escapement mechanism and the platen carriage, means whereby this supple- 13 mental-frame is sldable rectilinearly dovvn behind'the universal bar to. obtain compactness.

9. The' combination with a base-frame 5 carrying printing instrumentalities, including a segment and a universal bar, of a supplemental-frame slidable rectilinearly down behind the segment for compactness, said supplemental-frame carrying a platen carriage and a complete escapement mechanism, the latter depending from the supplemental-frame to bring its operating elements into operative relation with the universal lbar when the supplemental-frame 'is in its. extended or loperative position.
