DRAWER-SUPPORT FOR FILING-CASES.

` Patented March-24l, 190B.

Application ma umh 1e, 1905. serial No. 250,348.

Be it known that I, PHILIP H.}YAWMAN, of Rochester, in the county of Monroe and\ State of New York, have invented certain new and useful Improvements in Drawer- Supports for Filing-Cases; and I do hereby declare the following to bea full,clear, and of the same, reference being had to the accompanying drawings, forming a partV of this specification, and to marked thereon.

My present invention relates to im rove-v ments in cases for filing documents andp otherpapers of various descriptions in drawers of comparatively large capacities, and it is the purpose of my invention to provide su porting devices for these drawers which wi l pos sess am le strength with the-least weight of materia and which will enable the drawers to be easily withdrawn and returned `to the filing case althoughthey may be heavily loaded with papers or documents, and which will prevent the drawers from binding excessively and sticking within the case from warping or other causes which would prevent or render diiiicult ythe manipulation of the drawer.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more ully explained, the novel features being pointed out .in the claims at the end of the specification. V

In the drawing: Figure 1 is a vertical sectional view of a portion of a ling case showing extensible supportsconstructed in accordance with my invention applied thereto, the upper drawer being shown in closed position and the lower drawer being shown withdrawn from the case; Fig. 2 is a sec tional view on the line 2-2 of Fig. 1, showing the supports and their ways in transe verse section; Fig. 3 is a .perspective view of one of the supports removed from the case illustrating in dotted lines the manner of inserting and removing the drawer rollers from the upper ways of the support, and Figs. 4 and 5 represent in side elevation, and transverse section respectively, a modied form of support which may be similarly applied to the case for supporting the drawers thereof. v

The purpose of my invention is to provideextensible supports of this kind which may be applied to filing cases or other furniture -comparatively light in site sides, the intermediate flange 8 an of a similar nature for guidingland supporta minimum amount of friction to enable the latter to be ing the -drawers thereof wit readily and easil handled even though they may be heavily oaded or weighted with papers, the particular construction of the su ports or ways being such that they may fi) interposed between the drawers and the adjacent walls of the casing with a minimum amount of clearance, and as they are preferably constructedl their peculiar formation will insure .ample strength to prevent sagging of the drawers, whl e the parts may be weight and cheaply manufactured.

In Pigs. 1, 2 and 3 I have shown onesform of my invention applied to the ordinary wooden filing cases, the vertical walls 1 thereof between which the drawers areA adapted to fit being provided with the horizontally-extending vstri s 2 preferably of sheet metal and securedp in any desired way to the opposite walls of the drawer opening at the same level, and on each of these strips are journaled a series of. rollers 3, 4 and 5 which are mounted to ,rotate in a vertical plane. The upper bearing surfaces of each series of rollers are arranged in the same horizontal plane, but the rearmost roller 5 is of smaller diameter than that of the intermediate roller 4 and the `forward roller 3. The particular form of supports which I prefer to em loy in connectlon with these supporting rdllers are each made of substantial i the

channel bars

6 and 7 arranged edgewise and 'having their channel openings at o plpt e upper flange 9 with its overhanging ed e .10 forming horizontal ways at the top o' lthe su thIe) ower flange 11 with its upturned edge 12 forming separate ways in the lower portion of the support. In the lower ways formed between the horizontal flanges 8 and 11 are adapted to rest the rollers 3, 4 and 5 which are relatively fixed upon the case and vlocated therein is a stop 13 formed in the present instance by extending a pin from the upturned edge 12 inthe lower portion of the ways transversely across the path of the larger rollers 3 and 4, the position of this stop being such as to permit it-to ass the smaller roller 5 and cooperate with t e intermediate roller 4 to arrest the rearward motion of the movable supports. In the upper ways the ort, and the intermediate portion 8 vand 95 rollers 14 anfd 1,5 'ournaled at'e'ach side of the drawer 16 are a a ted to run, an abutment 17 being provide at the rear ends of the u per ways to engage the rearmost rollers 15 of) the drawer t0 act as stops between the latter and the support when the drawer is moving rearwardly, and at the forward ends of the upper ways are provided the roections 18 which act as stops to l1m1t t e orward motion of the drawer relatively to the supports, the intermediate section of the ways being of sufficient length to enable the re uisite motion of the drawer. he upper flanges 9 of the upper ways are preferab cut away for a sufficient dlstance rearwardy of the projections 18 to enable the rollers 14 and 15 of the drawer to pass longi udinally into and out of the ways after being lifted o ver the stops 18 for the purpose of removing the drawer, the downwardlyextending edge 10 of the upper flange 9 bereferably extended forwardly to form a 1 e which coperates with the inner sides of the rollers to 1nsure their proper insertion Within the ways.

The supports shown in Figs. 1, 2 and 3 may be readily formed of sheet metal possessing sufficientstrenglth and stiffness, for it will be understood t at the sides of the upper and

lower ways

6 and 7 may be readily roled or otherwise bent so as to extend on opposite sides and at right angles to the intermediate flange 8, and the edges of the ends thus formed ma be again bent at right angles, or paralle to the lntermediate flange 8, and in opposite directions to form the upper and lower flanges 9 and 11, the edges of these flanges being turned inwardly or toward the intermediate flange 8 to form the substantially arallel edges 10 and 12 respectively Whicli are offset at opposite sides of the support. In this way theupper and lower ways which extend longitudinally of the support arein substantia ly the same lane, but are arranged at opposite sides oft e intermediate flange 8, and the latter acts as a track on which the rollers 3, 4 and 5 of the case, and 14 and 15 of the drawer, `are adapted to run. The sto 17 at the rear ends of the upper ways in t 's form are referably made by bending a portion o the lmaterial composing the support laterally so as 'to extend' transversely of these ways, and it is preferable to fit a band of rubber or other resihent material 19 over this sto which may act as a yielding buffer to re uce the shock that might be caused by contact between it and the rollers 15 of the drawer. The forward stop 18 may be formed in a similar way by bending a forwardly-extend- 4 ing portion of the sheet material in a direction transversely of the u er ways, an ear 18' thereon being preferallslp flan e 8 to renforce the s ot, and the forwar extension of the edge 10 of the upper secured to the flange 9 may be produced by4 removing a' portion of the upper flange 9 to provide the aperture for the passage of the drawer rollers and leaving a portion of the edge 10 to form this guide.

Instead of manufacturing the guide Ways o r supports each of one single piece of mate'- r1al, 1t may be preferable in some instances to form them of'two or more similar sections suitably united, and in Figs. 4 and 5 I have shown a modified form of support which is made up of similar sections`20 and 21 secured together by the rivets or other fastening devices 22. Each of these sections' comprises the

channel bars

23 and 24 of suitable len th, and each of these channel bars has one o its longitudinal edges turned or bent over to form a semi-circular track or

guide

25 and 26, the opposite longitudinal edge of each section bein curved laterally in an arc of approximate y a uarter of a circle as at 27 and 28, Aand is t ence bent substantially arallel to the body portion of the section to orm the attaching portions 20a and 21a and the edges of these attaching portions are bent or curved laterally to form the

sides

29 and 30 of the up er and lower ways. The similar sections t us formed arebrought together so that their attaching portions 20a and 21a are in proper relation and are then secured by the rivets or securing devices 22, thus forming a support having the upper and lower tracks or channels at the opposite sides thereof. The forward end of the u per section isl lrovided with a stop 31 whic is preferably ormed by bending the correspondin edge of the material laterall so as to exten transversely acrossv the trac and at the rear end of the same section a similar stop 32 is rovided, preferably in the same way. Be- 'nd the stop 31 at the forward end of the section the up er flange or guide 25 is cut vaway for a su cient distance to permit the rollers of the drawer to pass into and out of the up er track or ways, and at the rear and in the ottom of the lower section is provided a suitable stop 33 which may be formed in any desired way, and is of sufficient height to engage the rollers 3 and 4 of larger diameter on the casing to arrest the forward motion of the supports andV to permit the passage of the smaller rollers 5 in a manner s1milar to that described in connection with the stop 13, which is used on that form of support illustrated in Figs. 1, 2 and 3. When supports of this kind are employed wherein the tracks are curved in cross section, correspondinglyformed rollers 34 are employed which may be made of fiber or other composition, and

other places where a minimum clearance bctwecn the drawer and the wall ofthe casing is obtainable, and by forming the tracks with a curved cross section, the rollers will be so guided as to insure the proper action of the drawer withoutibindingagainst thcl walls of the casing.

Drawer su orts of the kind described may be readlii;r formed of sheet material either in one integral piece, or-made up of sections suitably united, and in cach case the weight of the parts will be inconsideralle while the maximum strength is secured, for it will be observed that each of the supports is made up substantially of two oppositelyarranged channel bars placed edgewise, and therefore theweight of the drawer, when it has been withdrawn from the case, will be easily sustained without sagging or bending the supports, and at the same time lateral -motion of the drawer cai'lsed by bending of the supports laterally will also be prevented. Moreover, by using the rollers inconnection with the guide ways of the supports and so arranging the latter that theyl may move freely relatively to the drawer and the case, drawers of considerable weight may be easily handled with a minimum friction, and the operation of the arts is practically noiseless and secure from erangement while the wear of the parts is' insi nilicant, and for this.

reason, the top of t e drawer will always register closely with the casing which forms the top of the drawer opening, and the s ace which usually develops during the use o the yordinary drawer on account of the wearing away of the co erating parts of the latter and the casing r oes not occur in the use of drawer supporting devices constructed in accordance with my invention.

Although it is preferable to employ the `supporting rollers to operate in the ways of the extensible supports for the reason that friction and wear of the parts is reduced to a minimum, it will be understood that su porting devices of any suitable form may e employed instead of the rollers and the ways of the extensible supports may be correspondingly formed to accommodate the artlcular form of supporting `devices whic it is desirable to employ.

'In carrying my invention into practiceit is preferable to so form the extensible supports that the rollers or other supporting deg vlces arranged on the casing and the drawer will be provided with stops to limit their vertical motion while they occupy any posi- 1 tion on their respective ways, and in both forms of my invention herein shown, each ofthe ways are formed between up er and lower tracks or guides, so that wliien the drawer and the supports are withdrawn from ythe casino', the forward lrollers 14 of the drawer will rest upon the lower guide of the upper ways while the rearmost rollers 15 will bear against the upper guide thereof, and in a similar way, the forward rollers 3 of the liling case will bear against ,the upper guide of the lower ways while the rollers 4 will bear against the lower guide thereof, and therefore it will be obvious that sagging or tilting of the drawer and the supports at their forward portions is eectually prevented, and as these rollers or supporting devices are closely confined by these guides in a vertical plane, the motion of the drawer while being withdrawn and replaced within the casing will be in a straight line, and will not be deflected downwardly toward the forward part of its motion, and these results are secured with supports that are extremely compact, requiring very little space betweenv the drawer and casing.
