TYIFEWRITING MACHINE.

Application filed May 12, 1926. Serial No. 108,495.

This invention relates to sound-deadening casings for typewriting machines, and is especially intended for use in connection with machines of the portable class.

The machine may be mounted upon a baseboard, and provided with a sheet-metal casing including a displaceable top having a glass panel. The keyboard of the machine protrudes to the exterior of the casing and is operated in the regular way. The-carriage is controlled from the outside of the casing by'means of a handle pivotally mounted in the casing, and effective by .mcans of a gear-sector and pinion to revolve a drum. A cord is wound around this drum and connected to the line-space lever of the machine to return the carriage and linespace the platen.

Another feature of the invention relates to novel means for releasing the carriage without necessitating the lifting of the cover, and this means includes a bar extending lengthwise within the casing and engageable with the carriage-release lever. The bar is pivotally mounted in the end walls of the casing, and is normally held free from the carriage-release lever by means of a spring. the bar being swingable into engagement with the lever upon the depression of a button provided on the outside of the casing.

Another feature of this invention relates to novel means for resiliently securing the machine to the base-board in a manner to further soften the noise arising fromthe operation thereof. To this end, there is provided a pad of sound-deadening material uponwhich the feet of the machine rest. At the rear thereof, the machine is secured to the board by means of a clip permanently secured to the board. Said clip has a hook designed to engage in a hole in the rear wall of the machine-frame. The front part of the machine is secured to the board by means of screws which are passed through brackets fast to the frame and screwed into threaded plugs driven into the board from the bottom thereof.

Other features and advantages will here inafter appear.

The Underwood portable machine is provided with a frame 10 having a front extension 11, which encloses a series of depressible keys 12 and a traveling carriage 13,

which is normally returnable by means of a line-space lever 14. The frame 10 is secured toa baseboard 15 by means of a clip 17 designed to engage in a hole 18 in the rear wall 19 of the frame, said base-board being provided with a felt covering 16. The clip is permanently fast to the base-board by means of screws 20, and the machine is .cushioned with a felt pad 21, mounted be tween the base-board and feet 22 fast to the frame, as shown in Figure 5. The front part of the machine is provided with angular plates 23. fast to the frame by means of screws 24:. The angular plates 23 are perforated to receive screws 25, which are threaded into metal plugs 26 driven into the board. To further cushion the machine, there may be provided rebound rubber washers or sleeves 27 under the heads of the screws 25.

In order todeaden the sound arising from the operation of the machine, there is provided a casing having a rearwall 28 and side walls 29. The rear and side walls may be made of a continuous piece of sheet metal, which may be further extended at the front thereof to provide a front wall 30. The front wall 30 has an opening 31, through which the keyboard-extension 11 protrudes to the exterior of the casing, thereby ren- The walls of the casing are fast to the base-board 15 by means of screws 32.

According to certain featuresof this invention,.there is provided a front-plate 33, which is shaped to conform with the front wall of the machine, as shown in Figire 2.

I Figure 6.

Said plate is lined with sound-deadening material 34, and has extensions or plates fast thereto'by means of rivets 36, the plates being provided with slots 37 designed to engage studs 38 fast to" the front wall of the casing. The plate 33 is secured to the front wall by means of winged nuts 39.

The carriage-return lever 14 is provided withan arm 40, secured thereto by means of a screw 41. Said arm carries at the end thereof a cord42wound around a drum 43 fast to a shaft 44. "Said shaft is journaled in a supporting bracket or base 45, and carries at the end thereofa beveled gear 46 designed to engage a gear-sector 47 pivotally mounted upon a shaft 48. The sector is normallyheld in the position shown in Figure 4'by means of a comparativelyolight spring-49, which is effective to take-up the slack of the cord and is wound around the shaft 48. The tension-of the spring may be riage is letter-spaced, the cord 42 will rotate the drum 43, and thereby lift the handle 51, which will reach its uppermost position when the carriage reaches its extreme lefthand'position. Then, in order to return the carriage, itis only necesary to depress the handle 51. The-l-drum 43.is provided with .aguard 54, to retain thecord 42in a groove 55. Said guard-isheld in place by means of a screw 56, which prevents the guard from-rotating.- The screw may be locked by means of anut 57. It will be seen'that the carriage-returning devices described are all carried on the base 45, and form therewith a unitwhich is'readily attachable to the base-board 15. A carriage-release lever. 58 is pivotally mounted on, a platen-shaft 59, and engages with an intermediate lever 60,'which carries a .rack 61 operatively connected to a linespacin'g mechanism 62. *Said lever 58 is die PrQSSIblQ; to thus free the carriage and perthemovement,thereof, by means of a git-oss ba-r 63, whichis journaled in holes 64 m the-end walls ofthe; casing. The cross 7 vliar: isoperatively connected, by means of an 'arm 65, toa finger-piece 66, carried by a rod '67,,sl1dab1ymounted in the front wall of the casing; The rod 67 is mounted by means of apin 68,0nthe arm-65, and is held in its i'nelfeotiveposition by means of a spring 69, actuating between the] arm and a supporting bracket 70, fast to'lthe base-board by means of one of the screws .32, as shown in In order to facilitate the positioning of the carriage without necessitating the displacement of the cover, there is provided a special scale 71, mounted upon the front wall of the casing by means of a frame 72, both the frame and the scale being secured to the casing by means of screws 7;. The face of the scale is graduated to correspond with the graduations on the regular scale on the carriage, which determine the position thereof, and is ourvated radially with the axis of the shaft 48. Since the purpose of this scale 71 is to indicate the position of the carriage relative to the printing point, there is provided an indicator or pointer 74, which may be secured to the lever 52 by means of rivets 7-5.

The noise ensuing from the operation of the machine is confined within the casing by providing a sound-deadening lining 76 and a cover 77. The latter is pivotally mounted upon a hinge 78, and is provided with a glass panel 79, which is secured to the cover by means of clips 80.

Since the unused portion of the work-sheet is confined within the casing, the trailing edge thereof is liable to drag along the felt lining and otherwise engage with some of the operating mechanism within the casing. To overcome this, there is provided a sheetmetal plate 81, which is curled at the bottom thereof to form a channel, as shown in Figure 4. The plate may be secured to the rear wall of the casing by means of screws 82.

,Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
