Claims.
The invention relates to improvements in ma chine supports, and has for its principal object to provide an improved, simple and inexpensive supporting means of the cushion foot type for ma- 5 chines, and particularly for portable typewriting machines, for reducing operation noises, absorbing shocks, and preventing sliding of the machine upon a desk top or other supporting surface. The invention provides a simple, inexpensive and effective assembly of machine frameand rubber supporting feet, and one wherein high cushioning efficiency is attained with substantially no tendency of the machine to wobble laterally while in operation.
To the foregoing and other ends which will hereinafter appear, the invention consists in the features of construction, arrangements of parts, and combinations of devices hereinafter described and particularly pointed out in the appended claims.
In the drawing illustrating, in connection with a portable typewriting machine, the preferred embodiment of the invention,
Fig. 1 is a fragmentary top plan view of the rear end of the machine showing two rubber feet and their mountings located at opposite sides of the machine; I 1
Fig. 2 is a vertical transverse sectional view on the line 2-.2 of Fig. 1';
Fig. 3 is a vertical transverse sectional view on the line 33 of Fig. 1;
Fig. 4 is a detail top plan view showing the left hand corner of the base plate of the machine and a bracket welded thereto; and
Fig. 5 is a perspective view showing, on an enlarged scale, one of the rubber supporting feet.
Only so much of the machine as is necessary to an understanding of the present invention is shown in the drawing and will be described.
The rear end portions of the two vertical sheet metal side walls or side plates of the main frame of the portable typewriting machine are designated II] in the drawing, each said side Wall portion being formed with an integral horizontal flange H extending inward from the lower edge thereof. Beneath the main frame is a thin sheet metal base plate l2 formed around its outer edge with a low upstanding flange l3. The main frame and base plate are detachably connected in vertically and slightly spaced relation. The two connections shown at the rear of the machine each comprises a sheet metal angle bracket l4 having a vertical portion detachably held to the outer face of the adjacent wall portion ill by suitable fastening means such as screws l5, and having a horizontal portion extending outward from said wall portion l0 and spot welded at It to the upper face of base plate I2.
The assembled main frame and base plate are supported at the rear of the machine by two rubber feet I! molded of soft live rubber. These feet are of very small size and very low height, the several parts hereinbefore described being shown full size in Figs. 1 to 4 of the drawing, and one 1 of the feet beingshown on an enlarged scale in Fig. 5. 1
Each rubber foot ll is a solid body or mass of the softlive rubber, that is, the foot is not formed with a bore therethrough nor is it formed with a l5 central cavity in its lower face. Each foot consist of a lower stem portion iii of cylindrical cross section and an integral upper head portion I9 of cylindrical cross section and of larger diameterv than the stem portion. The stem portion is of greater height than the thickness of the thin sheet metal base plate l2, preferably about three times as high as the thickness of said plate. The small vertical spacing of flanges I i above plate 12 is preferably substantially less than the height of foot stem portion is, and the height of the head portion l9 preferably equals the said small vertical spacing.
Beneath each flange H of the main frame the plate 12 is formed with a circular aperture 20 the diameter of which corresponds with the diameter of the foot stem portion I8. The stems of the rubber. feet are passed downwardly through apertures 20, and the machine frame and base plate are fastened together by screws l5 with the flanges ll seated on the heads IQ of the rubber feet H and with said heads confined between flanges H and base plate l2.
It will be observed that the construction described permits lateral expansion of the foot, under downward shocks, substantially from top to bottom of the foot, and that the foot takes the load at the upper face of the foot, thereby utilizing the full length of the foot as a cushion substantially free from end to end to expand place by the assembled machine frame and the base plate, thus saving provision of special foot securing means.
What I claim is:
1. In a portable typewriting machine, in combination, a main frame, a sheet metal base plate underlying said frame and formed with an aperture near one side edge, an upstanding flange carried by the base near its side edge and adjacent said aperture, an upstanding flange at the side of the main frame and adapted to contact the inner side of the upstanding flange on the base plate to position the main frame on the base, an inwardly extending horizontal flange on the main frame overlying the aperture in said base plate, a soft rubber supporting foot for said aperture, having a head portion confined between the horizontal flange on the main frame and the base plate and a reduced stem portion extending through the aperture in said base plate and forming a yielding friction gripping foot to support the machine, the said horizontal flange being seated on the said head portion, and means detachably securing the upstanding flange of the base plate to the upstanding flange of the main frame to lock the foot in the apertures in the base plate.
