UNITED. sTAr s OSCAR WOODWARD, OF MONTCLAIR,

NEW JERSEY,- AssIeNo BY MESNE Assume MENTS, TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPO- RA TION OF NEW YORK.

To all whom it may concern Be it known that I, Oscar; \VOQDWARI), citizen of the United States, and resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Type-'Writing Machines, of which the following is a specification.

My invention relates to supporting feet for-writing machines and theprincipal object of said invention is to provide improved devices of the character specified.

To the above and other ends my inven-' tion consists in the features of construction, combinations of devices and arrangements of parts hereinafter describedand particularly pointed out in the claim.

In the.accompanying drawings, Figure 1 is a fragmentary side el'evation',:partly in section, showing part of the machine frame and one'of the supporting feet attached thereto, the view showing the inner-side of the forward left-hand portion of the base tional-view', taken on a plane represented by the line m;'c of Fig. 1 and lookmgjm the direction of the arrows at sa1d,.lme.

Fig. 3 is a vertical longitudinal section of the foot proper and its associate sleeve. Fig.

showing a modified construction.

Referring first to Figs. 1 to 5' of the draw-.

ings, 1 indicates the base frame of a typewriting machine, such, for example, as the No. 10 Remington typewriter. The side of the base is formed with a vertical semi-circular groove or depression 2. As shown in Fig. 2 the lower end of the groove is flared or tapered, as indicated at 3, to provide a socket portion. Secured to the side of the base as by rivets 4 is a foot bracket 5 of ing the groove 2 and being rounded or curved as indicated at 6, thus providing together with the lower flaring portion 3 of the groove 2 a foot receiving socket, the socket portion 6 complementing the socket TYPE-WRITING MACHINE.

portion 3. As is clear from F the .portion 6 is pressed or otherwise formed with corrugations to provide a series of grooves or depress ons 7 on the inner face.

My new. and improved supporting foot.

comprises a foot proper 8 of rubber or rubber composition or other suitable resilient -and. expansiblematerial, said foot consisting of a cylindrical base portion 9 audit tapered neck or socket-engaging portion 10,"

said 'neckflbeing'adapted to fit readily into the socket 3, 6 in: the machine frame. The foot proper isfOrmed with'ap vertical hole or bore 11, and the lower end of the bore '11 is enlarged or counterbored at v The bore [11 receives a lining in the form of 'a metal halves or-portions 14, as shown in Figs. 2, 3 and The diameter of the sleeve is such sleeve enmay readilybe slipped into the bore. The

but is of greater diameter than the sleeve, so that said head engages. directly with the lower end of the sleeve. The body of the screw is of such diameter that it passes freely through the sleeve but has no side play therein, the sleeve serving to center the screw and maintain the head thereof in en 'gagement with the lowerendof said sleeve.

The upper'end' portion of the screw '16 is reduced in diameter and threaded to coopcrate with the conical nut 17, which when screwed down, seats itself in the bevel 15 at the upper end of said sleeve. The outer surface of 'the nut is knurled, corrugated or roughened, as shown at 17*, Fig. 4, so that the corrugations or knurls act as projections provided with a head 18 which is adapted to pass freely through the counterbore 12 75 tube orsleeve 13 which may comprisetwo.

which it will catch on the corners of the sec-- ticnal sleeve or split tube 13, thus preventing the nut from rotating when the screw 16v driver;

of the is rotated by a screw Prior to the insertion foot in the machine the screw 16 and nut 17 soloosely engage the sleeve or tube l3'that the latter the tube 13 and the expanding devices 16.

the

and 17 may be readily, arranged in place,

- tapered neck or-socket portion being forcing the halves or Fig. 2 wherein Q outward or radially;

more evenly j the outward easily inserted from the bottom upward in the flaringisocket 3, 6. Thereafter the screw 16 is rotated by a screw driver, the rotation of the screw operating to draw. down the conical'nut into'the sleeve or tube, parts of the sleeve apartfat their upper ends as illustrated in the sleeve sections are shown from the bottom upward, thus diverging 1 causing \l-shaped openings or spaces 14"" between the sleeve sections." The relative movement of the sleeve parts operates in turn to expand the rubber,'forcing it outward andcausing it to press'tightly against the inner walls of the foot socket; and also to fill the depressions 7,1thu's rendering'more difficult the accidental removal or displace 'mentof the foot. Thus it will be notedthat the head of'the bolt or screw bears at'one end of'the sleeve and the nut at the opposite end, and when the bolt is turned, the head and-nut act compressively endwise on the sleeve and at the same time the upper part of the sleeveis expanded to force the rubber laterally so as socket. It will be observed that the screw and nut, instead of co-acting directly with the rubber foot proper, co'dperate instead indirectly therewith through the interposing the sleeve between the expansi ble foot and the expanding devices the expansive force of the latter is transmitted sleeve this force would in large measure be transmitted upward and downward axially of the screw and would tend to -com-.

press the rubber in an up and down direction rather than expand it outwardly. Furthermore, the sleeve operates to transmit pressure or expansive force tothe neck 10 than would be the caseif the expanding devices operated directly on the foot proper.

The foot as an entirety may be removed b turning, the screw backward, which ordi narily will cause its head to move downward away from the tube or sleeve without forcing the conical nut upward. After the screw has been given a few left-hand turns it may be pushed in until its head rests against the lower end of the sleeve 6, forcing the expanding nut out of the tube and to interlock with the sleeve 13. By

whereas. without the permitting the foot to contract so that it may be easily foot socket. Various departing from v the scope of my invention.

For example, the expansible sleeve or tube, instead of being made in two-independent drawn downward out of the changes may be- ,made without from the top at a number 21. 7 Fig. 7"shows a one-piece tubeor sleeve '22 which as indicated at 23',-is split throughout its entirelength; while Fig. 8 shows a .sleeve 24' composed of three sections '25. I

In Fig. 9.; is illustrated a modified construction' of receptacle or socket for the foot.

In the Fig. 9 construction the 'bracketlfi of the Fig.1 form is replaced by a bracket which instead of a wide,

or bridging portion'6 has a narrower, plain, strap-'likebridging portion 26. This" strap portionis slightly inclined toward the tapered socket portion 3 on the f-ramefproper, thus providing a plain of less height than the corresponding socket of the first described constructionl The supporting foot as a whole comprising the foot-proper 8, the sleeve sections 14, the screw 16 and the nut 17 may be introduced into the socket 3, 26 from the bottom upward as before, but in this case the upper end of the-neck: 10' will project abovethe top of thejsocket portion 26. The consev quence will be that when the screw and nut are contracted by drawing down the nut to expand the neck, the portion thereof contiguous to the ,strap 26 will be. forced or pressed outward very tightly against said. strap while the part of the neck above the strap will bulge over the top of the strap as indicated at 10*. It will be apparent that the-bulge will edectually lock the foot in place and, will prevent accidental withdrawalthereof from its socket or receptacle.

-Other changes in constructionwill readily suggest themselves to those skilled in the art. I

It will be understood that while have shown and described one supporting foot the machine is provided with a plurality of these feet, four being the number ordinarily employed.

It will be seen that I provide a foot which may be readily inserted in place in the machine and" as readily removed therefrom; that said foot, after it has been arranged in place,"may be expanded so as practically corrugated curved tapered socket 3, 26

to prevent accidental removal or displace ment; that removal is prevented both by the abnormal friction between the foot and its socket and also by the locking action exerted in the Fig. 1 construction by the rubber Such which fills'the depressions 7 and in the Fig.

construction by the bulge or overlapping portion 10*; and that in both instances what may be termed-the locking portions of the foot are expanded or pressed outward radially beyond the interior wall of the socket. prevention has been a result long I sought, the dropping out or accidental pullmg or forcing out of the rubber foot being 10' of different diameters, the bottom heretoforeone of the commonest and most annoying defects in typewriting machines. y improved. foot, it will be observed, is
