TYPEWRITING-MACHINE SUPPORT.
Application filed September 15, 1921, Serial No. 500,853. Renewed July 7, 1925.
This invention relates to means for supporting typewriters and more particularly to drop-leaf typewriter-supports for use in, connection with desks.
In. the application of Cornelius B. Cor coran, Serial No. 875,491, filed April 21., 1920 (now Patent No. 1,418,701, dated June 6, 1922), it is proposed to use a drop-leaf or support in the form of an open frame for the purpose of reducing the weight of the removable parts and of avoiding the noise, due to resonance, of a solid base or support which would act as a resonator and increase the noise of operation.
The main object of the present invention is to provide improved typewriter-supporting means open beneath the machine so that undue noise due to resonance will be avoided, and protecting means to extend across said opening, said protecting means being light in weight, so as not to counteract the decrease in weight of the supporting means, and being easily removable for cleaning purposes.
According to the embodiment of the invention herein disclosed, the typewriter is placed. on a rectangular open frame and secured thereto by suitable means, such as screws. The typewriter with the open frame attached may then be slid into position in a support which may be in the form of a dropleaf for a typewriter desk. The support comprises an open base portion on which the I open frame mayrest on side guides at sufficient distance apart to receive the open frame. the side guides being provided with inward extensions or flanges to overlie the sides of the open frame when the latter is slid into position on the base, the sliding movement of the open frame being limited by suitable means at the rear of the leaf or support. The leaf may be pivoted on opposite sides to the end sections 'of the desk and may be connected in any suitable manner with the cover, so that when the cover is shifted to open positionthe typewriter will be in position for use, and when the cover is brought to closed position the typewriter will be'in lowered position beneath the cover.
Itwill be evident that, although the dropleaf has been rendered lighter than usual and noise due to resonance has been avoidedbyuse of the open'structure, the typewriter willbe exposed'to dust from beneath and be slidably mounted on the lower side of the support or leaf so that it may be easily placed in position or withdrawn for the purpose of cleaning.
Other features and advantages will hereinafter appear.
In the accon'ipanying drawings,
Figure l is a diagrammatic side View, partly in section, showing my invention in connection with an Underwood standard typewriter.
Figure 2 is a front view, partly 111 section, of the lower part of the structure shown in Figure 1.
Figure 3 is a perspective view of the open frame to which the typewriter is normally attached, the position of the typewriter thereon being indicated in broken lines.
Figure a is a perspective view, showing the drop-leaf with the protector applied thereto. I
A typewriter comprising keys 11, a platen 12, a traveling carriage 18, a frame 14 and feet 15 is placed on an open frame or base 16 so that the feet 15 rest onthe sides 17. The typewriter frame 14 is provided with internally threaded lugs 18, and the frame 16 is provided with openings 19 immediately beneath the lugs, so that screws'20, inserted through the openings 19, may be screwed 1 into the threaded openings in the lugs 18 to hold the typewriter in position onthe frame 16. The openings may be countersunkat their lower ends. so as to receive the heads of the screws 20', and the screws 20 may be locked in position by means of lock-nuts 21 placed on the screws before the latter were screwed into the lugs 18.
To support the frame 16, provision may be made of a drop-leaf 22, pivotally mounted at 23 on the ends or drawer-sections of a desk 24, and the leaf 22 maybe connected with a cover 25, so that, when the cover 25 is shifted to the position shown'in Figure 4, the leaf 22 will be in substantially horizontal position, but when the cover is lifted and swung to position to close the opening in the top of the desk the leaf 22jwill'beI swung downwardly, so as to carry the"ma-" chine mounted thereon. beneath the cover 25. The leaf comprises an open base 26 to receive the frame 16,'side members or guides 27 mounted on the base 26 at a suitable distance apart to receive the frame 16, and a cross-bar28 at the rear to limit the movement of the frame 16 rearwardly. Secured to the guides 27 by suitable means, such as screws 29. are angle irons 30, flanges 31 of which extend inwardly from the guides 27 so as to overlie the side edges of the fran'ie 16 when the latter is slid into position on the base 26. As shown in Figure 1, the different parts of the leaf 22 are so positioned with reference to each other that, when the frame 16 moved rearwardly into contact with bar 28. its front edge will lie flush with the front edge of the base portion 26. It will be evident that when the typewriter-(with the open frame 16 attached thereto, is placed in position on the leaf or frame 22, thetypewriter will be held firmly in position when the leaf is swung downwardly by the upward movement of the cover 25.
'Although the leaf 22 and the frame 16 have both been made lighter by construction in open form, and the resonance which would re'sultfro'm a solid support has been avoided. it will be evident that the stri'icture just described will have the disadvantages of permitting access of dust from beneath. and also :permit dust and detritus resulting from ensures and other causes to drop on the clothes of the operator and soil them. To avoid such disadvantages provision may be made of a protector 32 in form of an open frame 33 having stretched thereacross a fabric 34: of any suitable material. such as cheese cloth, and the leaf 22 may be provided on its lower face with angle irons secured thereto by any suitable means. such as screws 36. and having inwardly extendin flanges 37 so spaced from the lower surface of the leaf that the sides of the fr: me 3-3 may be introduced between the same and the lower surface of the leaf A flange or projection extending downwardly from the base 26 of the leaf limits the rearward movement of protector it will be obvious that any waste matter dropping through the machine will be caught by the protector 32 and that when it is desired. to clean the latter: it may readily be lQlIlQVQCl' and cleaned. 7
