B. C. STICKNEY TYPEWRITING MACHINE Filed Nov. 5, 1921 Patented July 21, 1925.
UNITED STATES BUENHAM C. STICKNEY, OF ELIZABETH,
NEKV JERSEY, ASSIGNOR TO UNDERWOOD TYPEWRITER COMPANY, OF YORK, N. Y., A. CORPORATION OF DELAWARE.
TYPEVJRITING MACHINE.
Appplication filed November To all whom it may concern.-
Be it known that I, BURNHAM C. STICK- NEY, 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 specification.
The present invention relates to sounddeadening casings for typewriting machines and more particularly to the window thereof through which the printing is visible to the operator.
It has been found that artificial light or sunlight, striking the window or windowpane at certain angles, is objectionably reflected into the eyes of the operator. To di vert such objectionable reflection of light, recourse has been had to angular adjustment, forward and backward, of the window-pane in its frame. Such adjustment in one plane, within the limits prescribed by the casing structure, may not always be sufficient; or, to be sufficient, might require a window-frame of otherwise undesirable dimensions. 7
An object of the present invention is the provision of means whereby the windowpane may be adjustable universally; that is to say, laterally as well as forward and rearward, to any angle required for satisfactory diversion of the reflected light.
In attaining this object of the invent-ion, and in the preferred embodiment thereof, the window-pane is mounted, for angular adjustment in one plane, in a frame which is itself mounted for angular adjustment, in the wall of the casing, in another plane, preferably at right angles to the plane of the first adjustment. 7
Another object of the invention is the provision of means for effecting a lateral, as contradistinguished from a forward and rearward, angular, movement of the window-pane, whether or not accompanied by means for efl'ecting such forward and rearward angular adjustment.
Other features of the invention relate to the means by which one frame is pivotally mounted in the other, and to means for providing sound-deadening joints between the two frames and between the pane and, the. frame in which it is immediately mounted;
5, 1921. Serial No. 513,001.
and to means for releasably holding theadchine shown therein.
Figure 2 1s a top plan view of the casing:
Figure 3 is a view, in cross-section, taken on the line 3-3 of Figure 2.
Eeferrmg to the drawings, the casing body 10 is shown as having a cover 11 hinged thereto at 12. On the main frame 13 of the typewriting machine'within the casing, the carriage 14 has letter-feed and return movements on a rear rail 15 and a front rail (not shown). The platen 16 is mounted for rotary movement in a platenframe 17 011 the carriage. The line-space lever 18, 20, is pivoted to the carriage at 19.
The casting forming the cover-portion of the casing is shown as having a rectangular ribbing 27 which re enforces the same and serves as a frame for a window-pane 28. The ribbing 27 is of considerable depthand provides a flange 29 on the outside of the cover and a flange 30 on the inside of the cover. The interior flange 30 serves as an abutment for the sound-deadening lining31.
A second window-frame or sash 32, conforming to the shape of the frame 27 is set snugly within the latter, and has ears 33 (see Figure 3) by means of which :it is pivoted to the frame 27. Screws 34, passing through the ears 33 and into lugs 35 which, are cast on the interior flange 30 of.
the ribbing 27, serve as pivot-pins for the sash or frame 32. It is to be noted that in Figure 1 the abutting sides of the frames 32 and 27 are straight whereas, as shown in Figure 3, the abutting ends of the frames 32 and 27 are curved on arcs struck from the pivots 34. Strips 36 of felt, leather or other sound-proof material, are preferably attached to the interior end faces of the frame 27 to make the joints sound-proof at these places. These strips 36, against which the ends of the frame 32 press, also have the function of holdingthe frame 32 in any angular adjustment thereof. Upon loosening the screws 34, the frame 32. may be adjusted platforms'43of the brackets. As shown in,
Figure l, the inner faces of the front and rear cro'ss-pieces' of the frame 32 are curved on an arc struck from the pivots 38', and are also preferably lined wi'th'strips 44 of fel or leather, or'other yieldable sound-deadening material, to render sound-proof the joints formed by the front andrear edges of the window-pane and the front and" rear cross-pieces of the frame 32. The front and rear edges of the pane 2,8 are shown as rounded so that, when the window-pane is swung on. its pivots. 38, the edges thereof may, move over the strips 44 Without jamming or tearing the latter. Upon loosening the'screws '38, the pane may be tipped for ward or backward to any desired angle; after which the screws 38"are tightenedto assist the strips 44'i'n'holding the pane in adjusted position.
It will thus be seen that the pane may be tilted forward or backward to any desired adjusted position of-the frame 32, and that;
the frame32 itself maybe tilted laterally to any desired angular adjustment of the frame 27. The frames are of a depth suffici'ent'to permit of considerable amplitude of adjustment.
Certain features herein disclosed-are made the subject-matter of the application of John Waldheim, Serial No. 512,741, filed November 4, 1921'; but noneo-f-the claims herein could be made in said Wald-heim app-lication. Thisinvention is in the natureofan improvement upon the structure shown in said application and in the patent grant;
ed t'o'said John Waldheim, July 1 1 924,
No. 1,499,709. Said VValdheim inventions are. in the natureof improvements upon the; machine cci'eredby an application Serial No.381,25as, filed by me May-14, 1920; The present case contains no claim that could be made in said application No. 381,259.
