f invention relates to supporting feet, of the general type used for supporting a light and delicate machine asthe same rests upona desk or table. a

' 1 More particularly stated, I seek. to produce i a supporting foot suitable for genera-l use in :therelation ust mentioned, but specifically ,adapte'dfor supporting a typing machine.

Inthis connection it may be statedthat a \msupporting foot for a typing machine .or

analogous mechanism should be so constructed and arranged as to ameliorate as far a as practicable theeffects of incessant pounding of the-human fingers upon the keyboard J of the machine, and also to take up any lost motion as betweenthe frame of the machine and thedesk or table upon which it is supported, and further to provide against scratching or other disfiguration of the desk a Ktop orthelikeupon which the machlne may be placed. a V a p I endeavor to obtain the advantages Just mentioned, bymeans of a supportlng foot of such form as to be cheap to manufacture, rel

a able in action, easily removed andreplaced,

andcomposed of parts readily standardized and, in every way suitable e for, quantity production, and adapted for use as separate feet wifor awide range ofdifferent articles including not only typing andlike mach nes but other articles for instance telephones, desk trays andfboxes of various kinds, and radio cabinets etc/.3 a, s i a 1 I endeavor further to provldea supporting foot which may if desiredbe made up in a part of a member which extendsscommon to amultipleof feet, said member for instance being suitable to V constitute the bottom 'wall of a cabinet or box andthe footstructures being formed thereonat spaced nointssuitablefor properly supporting the cabinet or Xbox. I h I Otherobjectsand aims {of the invention,

A5 more or less specific than those fre ferredlto above, ywillbe impart obvious and inpart pointed out in the course of the following description of the elements, combinations,

arrrangements of parts and applications of principles, constituting the invention and the scope of protection contemplated will be indicated in the appended claims,

Inthe accompanying drawing which isjto be taken as apart of this specification, and in WlllCh I have shown merely a preferredfform fie V of embodiment of=the invention Figure l is a substantially vertical section through one form of my improved supporting foot, and shows the same as ,mounte'd upon a typing machine frame. a 6, Figure 2 is a substantially central section through another formof supporting foot made in accordance with my inventiom but somewhat simpler than the form, shown ,in

Figure 1. v e A Figure 8 is a perspeotiveview of a sheet metal plate having a plurality of footlstjrnctures provided thereon, and

Fig. 4 is'a sectional view taken substaritially upon the plane of line VI-VIofFig- Z ure 5 and showing the'plate as it {would ,a'p-

pear in use forming. the bottom wallof a radio cabinet. y a

A portion of the frame of a typingemachine isshown at 5, and is provided with a'l 'basemember 6 integral therewith, this {base member havinga threaded. opening ,7.

A screw 8 is fittedinto the threaded opening 7, and is thus detachably carried bytlie a; base member 6. .This screw is providedzwitlrfi a eonvex head 9, which has a slot 10, to facilitate its engagement by an Ordinary screw driver. a

A metallic eyelet is shown at, 11 and is, providedwitha

pair ofannularfianges

12,13, ma-$ tegral-with it and each of substantially mushroom form.

The eyelet 11 extends through a circular washer 14 made of soft andresil-ient material, preferablytelt, and provided withlarcentral-i-wi? openingilti. a a

a The washer leis sandwiched between .an

, outer meta-llicshell 16:.and anjin ner metaillic shell 17 each shell having the priox imate form of a don1e,the outer, shell 1 6 having-aA longer cross diameter than the inner shell 17.

By virtue of theido nerlike form of each of

thetwo shells

16, 17, the feltwvasher lt, is

given a general cup-like The felt Wa r is Pr vided wi a annular po tio 9 18 which is substantially angular in cross section at its lower edge, as may be understood from Figure 1.

The weight of the frame 5 and part carried thereby rests directly upon the annular edge 18, which in practice flattens out a little, to fit upon a table or desk.

In the form shown in Figure 2 the felt washer 14 and the outer dome 16 each have a form like that shown in Figure 1 and above v described.

However, the inner dome shown in Figure 2 has the form indicated at 19 in that figure, and is provided with a neck-portion integral with it and terminating in an annular flange 21. The annular flange 21 extends slightly over and engages an annular portion 22 of the outer dome 16. Thus the neck portion 20 serves essentially as an eyelet, in much the same manner as the eyelet 11 above described with reference to'Figure 1. The chief difference between the form of my device shown in Figure 1 and the form shown in Figure 2 is, that in Figure 2 there are only two metallic members connected permanently with the washer 14, whereas in Figure 1 there are three metallic members so connected.

f I have found in practice that each form of my inventionis remarkably efficient, in the relation here contemplated.

By the use of my improved supporting foot the Weight of the supporting frame'and mechanism carried thereby is distributed equally, or substantially so, as between the several feet employed, of which there are usually four. 7

The washer 14 is preferably formed originally as a simple flat disk of sheet felt, with a hole at its centre, and it'is given the efficient cup or dome-like shape, as shown, by reason of the fact that it is clamped between two opposing cupped or dome-like members. This disposes the annular edge portion of the disk projecting downwardly at an outflaring angle and condenses and ruflies said edge portion so that it constitutes a desirably firm cushion for engagement with a polished table top or the like.

Because of the softness and resilience of the washer 14, due to the material of which it is made and the manner in which it is formed up, there is little or no lost motion as between the supporting feet and the desk or table upon which the same may rest. Since the annular edge 18 flattens out in consequence of the weight resting upon it, the supporting foot is to some extent automatically formed or shaped to rest upon the supporting surface which it engages.

Where the mechanism supported is subjected to incessant pounding, as by the action of human fingers upon a keyboard, the jar and shock is greatly ameliorated, both as to the fingers and the machine, by the use of my device. The machine is also protected from extrinsic vibrations.

In each form of my invention the structure is relatively simple. The various parts may be readily standardized and adapted for quantity production.

In .the form of my device appearing in Figures 5 and 6 it is contemplated that the outer shell member as 84 thereof, corresponding -With the shell 16 of Figures 1 and 2, shall be A felt washer 14 is fitted into the dome-like cavity provided by each of the projections and is held in its dome-like form by an inner shell and separate eyelet as in Figure 1, or by a combined inner shell and eyelet as in Figure 2. As illustrated the structure corresponds with that shown in Figure 2, and

while the plate 35 may be attached to the bottom of the radio cabinet or the like, as

36, by any appropriate means it is contemplated that screws or rivets extending through the centres of the foot structures may continue into engagement with portions of the cabinet for this purpose.

In instances where the cabinet contains some element, as forexample the so-called chassis as 37 of a radio set, the screws may engage such chassis to serve the double purpose of clamping the chassis against suitable stops as 38 within the cabinet and at the same time clamping the plate 35, with its improved cupped feet, in position as the bottom of the cabinet.

As many changes could be made in this construction without departing from the scope of the invention as defined in the following claims, it is intended that all matter contained in the above description, or shown in the accompanying drawing, shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention, what 'I'claim' as new and desire to secure by Letters Patent is I 1.
