Application filed August 20, 1921. Serial No. 493,786.

To all whom it may concern: I

Be it known that I, JOHN TALDHEIM, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specifica-t-ion.

' This invention relates to sound-deadening cases or hoods for typewrit-ing machines of the continuous billing variety, one form of which machine is shown in lVernery & Smith, No. 1,132,055, granted March 16, 1915. The sound-deadening casing or hood is of the general type disclosed in my prior application, Serial No. 466,820, May 4:, 1921 (now Patent No. 1,519,645, dated December 16, 1924;)

In the Underwood continuous billing or fan-fold machine, the usual letter-feeding carriage has a rearward extension, upon which a carbon-sheet carriage may move forwardly and rearwardly. Plies of work-webs, fed in from the rear of the machine, are interleaved with the carbon-sheets attached to said carbon-carriage, and the webs and carbon-sheets are drawn forwardly around the platen to the printing point. The webs usually comprise a succession of similar printed forms, and, when a form has been typed, the platen is swung upwardly and forwardly in a swing-frame mounted on the carriage, to permit the sheets to be straightened out so that the carbon-sheets may be more easily retracted to co-operate with a fresh portion of the worlrwebs. The typed forms are then ga-ged against a gage carried by the platenswing-frame and severed by a knife carried by said frame adjacent the platen.

The present invention provides a hood or casing which deadens the noises arising in the typing operation, while permitting easy access to and operation of the machine. For this purpose, the casing comprises a bodypart and a cover-part or cover hinged at the rear tosaid body-part, said body-part being provided with a large front opening to permit passage of the machine therein, and be ing sufliciently large to receive the entire machine with the exception of the banks of keys which project forwardly from the bodypart. A cover-plate is mounted at the front f the bodppart to close th front opening the patent to front door therein. The cover-part encloses the machine at the top and terminates at the front a short distance above the cover-plate, to form a slot through which various operating handles on the earriage'may pass to project outside of the casing; sound-deadening means being provided to close the slot. To permit easy access to the typewriter-carriage and to the carriageextension, upon which is mounted the carbon-carriage and over which pass the worlcwebs, and to enable the platenswing-fraine to be swung upwardly and forwardly, the cover-part is hinged near the extreme rear of the body-part, so that, when said cover-part is raised, the entire carriage and carriage-extension will be exposed. lVith the cover-part inraised position, the platen-frame may be swung upwardly and forwardly to permit the work-webs to be straightened under the platen in the usual manner and for the usual purpose. At cer-,

tain times it is desired merely to have access to the platen and its associated mechanism, as for the adjusting the work-webs around the platen. It is therefore a feature of this invention to provide the cover-part with an auxiliary or cover which may be raised or lowered independently of the main coverpart to permit access to the mechanism at the front of the machine. Said front cover is preferably provided with a wiiidowto permit the machine in the interior of the casing to be viewed. a Another feature of this invention is the provision of means whereby work-webs may be fed continuously throughsaid casing to the machine, without removing any part of the casing or forming an outlet for sounds.

Still another feature of the invention relates to means for releasing and lifting the cover by a single finger-piece. 7

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a side view, vertically sectioned, of the sound-deadening casing or hood applied to an Underwood continuous billing or fan-fold machine. 7

Figure 2 is a detail of a latch for holding the cover-part in position and means for simultaneously releasing the latch and raising the cover-part.

purpose of making erasures, or for and mountedin a platen-frame 17. Said platenframe forms part of a'carriage mounted for letter-feecing movementnpon a front railiZl andia rear rail 22 on the main frame 10. Said carriage is provided with a rear ward extension 95 support-ed at its rear upon a rail 26 on a rearward extension 27 of the. main frame 10, said carriage-extension-having side rails 2% upon which is mounted for forward and r arward movementan auxiliary carbon-carriage 25 having stepped side pieces 30 upon which are positioned clip-bars 31 for fastening carbon-sheets 32 to said carbon-carriage.

Plies of work-webs are led over a guide-barBG on the rear of the extension 25 between side gages 37 and interleaved with the carbon sheets 32. and carbon-sheets are their led forwardly beneaththe platen to the printing point. T he worlnwebs usually have printed thereon a series of simil risuccessive it'orm's, each of which is typedand torn air-before the next form is in position to be typed. When a form has been fullytyped; the platen 16 is swung upwardly and forwardly by means of-a swinging frame 39 in which said platen is journaled, said swinging frame being pivotally mounted inthe end walls of the platen-frame 17. The platen being thus swung upwardly and forward] enables the WO'll Wl)S and carbon-sheets to be straightened out, so that little resistance is offered when the carbon-sheets are retracted-to cooperate with a fresh portion of the webs by pushing"rearwardly a. handle fixed to the carbon-carriage 29, the rearward movement of said carboircarriage being limited by a stop ll. The type-d work-webs are then {raged against a gage =12 carried by the swinging frame 39, and are severed by a front knife 43 carried by said frame. To effect rotation of the platen, the end of the platen-shaft 45, by which said platen is journaled in said swinging frame, is provided with a gear-wheel lli in mesh with geanwheel t7, the axis of said gear-wheel 4:? being the axis al'iont which the piaten-frame is rotated, '50 that said and the to cause types 15 carried by said type bars to print against a platen 16' The work-websgcar-wheel :6 will be in mesh with said gear-wheel 1-7 at all times. To rotate said gear-wheel 47. there is provided a gearwheel 48 tired to a shaft d9, journaled in the end walls of the platen-frame 17 and operated by a knob or finger-wheel 50, or by suitable line-spacing mechanism, not shown.

To deaden the soundsa 'ising in the typing operation, there provided a. sounddeadening casing or hood having a bodypart indicated generally at 60, and a eover=- part indicated generally at 61 and hinged to said body-part on the rear thereof at 62, said body-part comprising a rear wall. til, side walls 65 and a. front wall in the form of two end portions-67, said end portions being spaced apart to permitv the insertion of the machine into the casing. The bodypart is provided with lateral extensions 66 over which the type-writ'er-carriage and ,its extension operate to the right and left, and with a rearward in which the rear of the carriagerextension operates. When the machineis positioned within the casing, the forward e2;- tcrsion or keyboard extension 12 extends forwardly from the casing to expose the banks of keys 13. To close all of the front opening not occupied by said forward. QX- ten ion '12, thereis provideda front coverplate 70, mounted upon said end portions 67 by nreans of turn-buttons Tl, having latches T2 fixed thereto, said latches passing through openings in said end portions and catchii'ig behind saidcndportions to llT-l the cover-plate in position. The body-part thus completely encloses the entire machine, with the exception of the forward extension 12, at the rear, sides, and front, said extension 2? of the carriage operating to the right and left over the lateralextensions (i6 and in said rearward extension (39.

To enclose the machine at the top, there is provided the cover-part 61, comprising a. forwardly-extending top wall or ceiling? and a. forwardly and dewnwa rdly extending front wall-T6, in whiohis positioned a. transparent plate '77 to permit themachine in the interior of the-casing to be viewed. The front wall 76 of the cover-part terminates above the upper edgeof cover-plate to form a spaceathtthefront through which various carriage-operating levers, such as the linespa ce handle 78, may extend. All of said slot not actually occupied ly the carriage operating levers is closed by a strip or cushion 79 of sound-deadening material, the two-ply edges of which are fixed upon the upper edge of the cover-plate. The coverpart may be normally pressed toward open position by means of spring 82 fixed at its forward end at 83 to the oody-part, and at its rearward end at St to an arm 85 fixed to the cover-part, so that said spring tends overhanging GXlZ'EZIlSlOIl 69 lit li o draw said armv forwardly, and hence rotate said cover-part upwardly about hinge 62. I

one end of 'a short shaft 92 rotatably mounted in aside Wall of the cover-part,

said latch being operable by a handle'87 fixed to the other vendof shaft 92 onthe' outside of said cover-part. if The latch engages a pin 88 on the body-part andis nor-r mally pressed into engagement with said pin by a spring 89. By properly rotating handle 87 against the action of spring 89, the latch 86 may be released, the handle 87 serving as a. means to assist in raising Ithe cover-part.

. In a continuous billing or fan-fold typewritingmachine, continuous webs 35 are fed to the machine, and this invention provides means whereby said webs may be fed to said machine from outside said casing without necessitating removal of any part of the casing, and-without providing an outlet through which sounds may pass. Said means comprises a slot 90 in the body-part, directly to the rear and beneath the guide-bar 36, through which the work-webs 35 may pass, the slot being closed by felt strips 91 fixed one to each side of the slot, so that the surfaces are in engagement with the surfaces of the work-webs, said strips thus closingall of the slot not occupied by said webs. The slot 90 extends completely across the casing, and, when the carriage and its extension move laterally from right to left, the work-webs will be carried between gages 37 to the right and left,.sliding in said slot 90 between said felt strips 91.

It will be apparent that the cover-part hinged at the rear at 62 to said body-part will, when opened, expose substantially the entire carriage and carriage-extension. Thus, in the position shown in Figure 5, the cover is raised to such a height as to permit the swinging frame 39 and the attached 42 to swing freely to its forward and upward position. The upward movement of the cover-part 61 may be limited by pin 101 on the body-part which engages the arm. 85 fixed to said cover-part. However, where it is not desired to have access to the carriage-extension, or where the swinging frame 39 is not to be operated forwardly, it is inconvenient Ito raise the entire coverpart. Thus, if erasures are to be made on the work-webs at the front of the platen, or where the webs are to be adjusted in position around the platen, it is suflicient to provide access merely to'the front of the machine. For this purpose, the front wall 76 of the cover-part 61 is constructed in the form of an auxiliary door or cover hinged at its upper end at 105 to the main coverpart, and swingahle upwardly .to expose the I i To maintain the cover-part in closed posi tion, there is provided a latch 86 fixed at front of the machine. The cover 76 is pro-v scope of the invention, and portions of the improvements may be used without others.
