To all-@hom it may concern: y

'Be it known that ll, AmNzo iB. Enr, a citizen of the United States of America', anda resident of Groton, county of Tompkins, and State of New York, have invented certain-new and useful llmprovementsI in .Cushioning Devices (Case No. 173)', of which,

the following is a full and clear specificav tion.

This invention relates to improvements in cushioning devices and means for connecting the same with a support.

The invention has for one of its objects thev provision of a cushioning device and supporting means theretorso constructed that the cushioning device may be readily connected with and disconnected from the support.

Another object of the invention is to provide a cushioning device and supporting means therefor so constructed thatthe cushionin device may be securelyconnected with lts support without employing extraneous fastening devices.

Another object of the invention is to provide a cushioning device and support having af quick detachable interlocking slip connection. v

A further object of the invention is to provide a duplex reversible cushioning device.

Stillanother object of 'the invention is to provide a reversible resilient cushioning device having oppositely disposed dished portions forming` suction gripping heads.

Tn the accompanying drawing,

Figure l is a .bottom plan View illustrating one embodiment of lthe invention, in

which the cushioning device serves as a cushionor foot for the main frame of a typewriting machine;

-orm of duplex or reversible per or cushion' and supporting means thereforg adapted for use as. alsupporting toot for typewriters or other'devices, .oras abumper for moving parts out ty ewriting machines,

evices.

Referring to lt1`igs'..l,.2 and 3 of the drawings b numerals, the cushioning device is forme able or resilient material and has two oppositely :disposed cushioning portions. or-

heads 1 connected by a reduced -cy'lindrica'tl portion 2. The top and bottom faces of the ycushion `are dished or cupped, as shown at` of rubber or other suitable yield- Y 3, to adapt either of the heads 1 to serve l l as a suction cup as well as a resilient cushion. The sides ot each head1 preferably curve inwardly, as shown, from the edge of the dished face thereof` to the contracted portion 2 to increase the eticiencyo 'the grippino` action of the suction cups thus formed.

T e duplex cushion may be connected to -variousarticles or machine frames such, for

example, as the main frame of a typewriting machine. TnllF-igs. l tor 3, T have shown the plate-like member or support l to which the cushion is attached as an integral en' tension of a horizontal flange 5 formed on the preed steel main frame 6 of a Corona or other typewriting machine, one corner f portion only of the frame-being shown.

lfVhile-T have shown the supportfl. as being formed integrally withthe machine trame, it will be obvious thaty the support may' comprise a separate plate fastened to the l frame in any suitable manner.

The'support 4r is formed with a circular aperture 7 of the same, or substantially the same, diameter `as 'the cylindrical shank portion 2 of the cushion, and said support is also formed with al throat or slot extending from one side ofthe aperture to the.

outer edge ot' the support. The inner end of the throat at its point ofconnection with the aperture 7 is of less width than the diameter of the aperture and 'the edlges 8 of the throat flare outwardly awayfrom each other toward the outer edge of the support, the outer end of the throat being preferably as wide-as the diameter of the aperture 7.

Tt will be obviousy that/the Icushion. may be readily-connected to vand disconnected from the machine frame by forcingthe con-- tracted shank portion 2.- laterally throu h slot' 8 into and out of aperture 7. T el inclined edges' 8 ot the throat serve. to gradually compress the contracted portion 2 of the cushion and thus-increase the easel with which the cushion may be attached. As soon as the contracted portion of the cushion enters the aperture 7 it will expandA to its original form, lfilling said aperture, and thus be securely held to the frame Without the necessity of employing screws, locking plates, or other extraneous fastening devices. lf one head of the cushion becomes Worn or damaged, thev cushion may be readily. detached and re-connected in re'-v versed position. l

lin Fig. 4 a cushion or suction foot is shown, having a dished or cupped portion 9, similar to the heads 1 of the duplex cushion above described, connected by a cylindrical contracted shank portion 10- with a cylindrical portion or Vhead 11 having a flat outer face. l

In Fig. 5 a support 12, having an aperture and throat similar to the aperture 7 and throat 8 in the supportv 4, is shown. This support 12 may be a part of a machine frame, as shown in Figs. 41,2 and 3, or may be attached' to or formed on various articles or machines', or parts of machine frames, to

' adapt the cushion carried thereby to serve asta supporting foot, a bumper for a moving machine element, or the like. The duplex lreversible bumper shown in this embodiment `of the invention has two cylindrical heads 13 connected by a reduced cylindrical shank portion 14 adapted to be forced through the ythroat and expand in the aperture `in the. support.

While I have shown the heads of the cushioning device, and the reduced portion vor shank connecting said heads, as circular in cross sect1on, it will be obvious ythat the shape of either the heads or shank in crosssection may bevaried and that the shape of the aperture 7 may be varied to conform with the shank portion 2. It will be obvious that the plate-like member to Which the cushion, suction, foot, orbumper is attached maybe of vaious shapes and may be formed on or connec ed in various Ways to machine frames and articles of yvarious kinds. The aperture and throat in the plate-like member form, in edect, a slot open at one end and closed at the other end and having a contracted' portion intermediate its ends. It will be observed also that the plate-like member and the cushion, foot or bumper are so constructed as to have a quick detachable, interlocking, slip connection that permits attachment ofthe foot, bumper, or cushion toI to the plate with either head thereof at one side of .the plate.

What ll claim is: i i

1. The' combination with the frame of a t pewritin machine, of a plate-like member t ereon a jacent the base of the frame formed with a slot open at one end'only and having a contracted portion intermediate its ends, and -a cushion of resilient material having a redured portion intermediate its ends of V,greater width than the contracted `portionl of said slot adapted te be forced therethrough and expand in the portion of the slot intermediate said conti-acted portion and the closed end of the slot.
