" "This invention relates to improvementsin slide structures for drawers, shelves andthelike.
The main obiectsoi this invention are:
(c1. 3il8 --6) culty has First, to provides slidestructure fordrawers,
shelves and the like which is easy in operation and at the same time f-ree' from vibration and rattling and' hence well adapted for use 'insup- -porting the doors of shelves in radio-phonograph combination machines and other relations where .such characteristics are desirable.
. second, to provide a slide structure having these advantages which is simple'and inegpen sive in its parts, the parts are easily assembled t been experienced in providing a suitably rigid structure andone v My present invention relates 'to a slide struc- ,'ture which is particularly well adapted for such uses but it will be apparent that it has many applications in other fields."- The structure of my invention while permitting free and easy manipulation and retraction of the slidably supported member, at the'same time prevents .rat-

my invention illustrated,
cabinet having. a door 2 for the radio receiver \and at the same' time durable and do not become loose even as the-result of longcontinued wear. Objects relating to details and economies of the invention will appear from compartment and'a compartment 3 provided with a door l for thephonograph mechanism shown conventionally at 5. ifhis phonograph mechathe description to follow. The inventon is defined and pointed out in the claims.
A preferred embodiment ofthe invention is illustrated in the accompanying drawing,. in
which:
Big. 1 is a fragmentary perspective view of a radio-phonograph combinationequipped with a slide 'struc ure embodyingmy-invention for slidably sup rting the phonograph instrument.
Fig: 2 is an enlarged fragmentary perspective viewtillustrating the slide rails and their relation' to each other and to the supported member. Fig. 3 is a, fragmentary plan view partially broken away and in horizontal section illustrating. further details of the slide structure and the videthe cabinets having at least one-half of.
the top thereof. hinged for opening .to expose the phonograph mechanism. This'opening of the nism is mounted onashelf or base 6 which is the supported member orelernent of my slide combination.
The slide structure in trated comprises the supporting rails I of channel section disposed in opposed inwardly facing relation' on opposite side walls of the compartrr int inwhich the supported element is housed or designed to receive the supported element or member 6 and whatever may be arranged there'- on.
being formed from suitable sheet metal stock having substantial spring quality, the legs 8 of the rails being-conformed to provide inwardly facing ball races, or ways 9, the ways or races I of opposed legs being in opposed relation, as
lid is unhandy and likewise prevents the cabinet being conveniently used as atable or stand or for papers, pictures, lamps, and the like. It has been proposed to provide drawer or shelf- J like slides for supporting the phonograph mechanism, leavingthe same to be pulled out for acclearly shown in Fig. 4. 'These races are of angular sided or'truncated V-outline for a purpose to be hereinafter described.
. The-slide bars l0 are also of channelsection and are disposed within the rails to face inward,- ly, these members being of such dimensions that they are entirely out of contact with the rails in their-operating relation. I
The web portions H of the railshave intumed ends l2 providing stops limiting the travel of the slide bars within the rails. K The legs H of the slide bars are provided with opposed. holes l4 therein receiving the anti-triction ball members l5. In forming the holes, I preferably strike ,up portions Hi at the edges thereof, as best shown in Fig. 6, to relievesomejter engagement of the balls with the slide bar andvice versa, the slide bar, inefiect, constituting a cage for the balls. These edges also pro-j vide a means to preload the balls 15 relative to cesa- So'far as the applicant is awar -much difli 88- the grooved races 9 of a rail 1, thus further elimifree fromvibrationsu I the embodiment illus-' These rails I are, as stated; of channel section,
what the frictionof the balls and provide a betnating vibration and rattling, The blank I! for one 01' the slidebars is illustrated in Fig. 5, the bending lines being indicated atslB.
'The supported member is provided with slides l8 and 20, these being also preferably formed of sheet stock. They are secured to the under side of the supported member 6 by meansof screws 2|. These slide members are disposed between i the balls l5 and slidably supported thereby, the
legs of the rails being under spring tension when the parts are assembled so that they constantly urge the assembled parts yieldingly together to eliminate friction. The portions of the members ii of the slide bars coacting with the balls serve to support the slide bars entirely out of contact with the rails.
The slide I 9 is conformed to provide a ball race or way 22, see Fig. 4, which serves as a lateral guide for the'supported member.
The slide is flat or at least its ball engaging portion is flat or plain so as to permit lateral movement thereof between the balls and thus prevent any bending and avoid the necessity for great accuracy in mounting the parts and'for center of the ball and its extreme periphery remote from the slide I9. Thus the ball rolls on the races 9 on a radius R while it rolls relative to the slide IS on a radius R which is substantially greater than radius R See Fig. 4. Hence the distance traveled by slide i9 and the supported member 8 on balls l5 bears a relation to the distance traveled by the balls and slide bars 10 on'the rails I which is expressed by the ratio This ratio is obviously I it follows that I am enabled to use rails l which are of relatively short length and still get a satisfactory great outward sliding movement of the supported member 6. For this reason, the structure is well adapted for use in comparagreater than unity, hence tively small cabinets having little depth. In addition a three point rolling contact is provided for the ball l5 which eliminates sidewise rolling clearance and afiords a more rigid, vibration free mounting.
At least one of the slides is provided with a stop 23 at its inner end limiting the outward movement of the slides and consequently the members supported or carried thereby. This stop 23 coacts with the inner end of the slide bar,
It will be noted that the slide l9 hasa downward offset 24 to compensate for the upward offset resulting from the forming of the ball way 22 in the slide and this arrangement permits the slide 20 being merely a piece of flat stock."
. I have illustrated and described my improvementsin a very practical embodiment thereof. It is believed that thiswill enable the application of my invention to a wide variety of uses particularly where free, easy operation is de" sired and that the structure should be free from vibration. I have not attempted to illustrate various other embodiments or adaptations which ways of said supporting rails adapt my improvements .as may I contemplate as I believe this disclosure will enable those skilled in the art to embody or I be desired.
Having thus described myinventiojn,- what I claim asnew and desire, to secure by Letters Patent, is: V
