' SLIDING cLosURE Filed Dec. '7, 1949 Patented Oct. 27, 1953 UNITED STATES PATENT OFFICE` SLIDING CLOSURE sigma P. xjellgren, Rockford, n1. Application December 7, 1949, Serial No. 131,577

This invention relates to a new and improved sewing cabinet, and has for its principal object the provision of a drum type table that is specially constructed in the top portion to house the sewing facilities, so that they are quickly and easily accessible when needed `but are completely concealed otherwise, the table retaining the external .appearance of a standard drum type table when the doors provided for the sewing compartment immediately belowthetop thereof are closed, so,` thatthe .table will befappropriate for use in a living room or wherever desired.

In the sewing cabinet of my invention, a circular tray `that is of slightly smaller diameter than the inside of the circular sewing compartment in the top portion of the drum type table is rotatably mounted on a slide guided in said compartment for lineal movement diametrically thereof and is arranged to `be pulled out about half way so that-everything kept in the tray is easily accessible bya slight turn of the tray.

VThere are two arcuate doors closing the front half of the sewing compartment, and these doors .areslidably guided in opposite directions in arcuate grooves provided in the top and bottom walls of said compartment, so as to move into the space between the periphery of the trayand the arcuate back wall enclosing the rear half of the compartment, each door being guided in its grooves by coaxially arranged combinationpivot and guide pins at the middle thereof and at least one other pair of coaxially arranged guide pins at the rear end thereof, the latter being movable from communicating grooves inwardly into the arcuate grooves when the front end of the door is pulled out slightly at the commencement of the opening operation as the doorpivots about its middle pins. coaxially arranged guide pins are preferably provided on each door between the other two pairs of pins, so that there will be two pairs of pins guiding the door when it is nearly half way open, thus insuring smooth sliding action of the door and avoiding the likelihood of the combination pivot and guide pins running outwardly into the communicating 'grooves previously mentioned and causing the outer surface of the door to be scuifed by sliding contact with the back wall of the compartment. The usual bullet type detents are preferably provided on the front end portions of the two doors arrangedto ride into the usual receptacles in the top or bottom wall of the sewing compartment.` i.

VThe invention isillustrated in the accompanying drawing, in which- Y l An additional pair of 4 Claims. (Cl. 312--307) Fig. 1 is a horizontal section through the sewing compartment in the top portion of a drum type table made in accordance with my invention, the section being on the line l--I of Fig, 2, and

Fig. 2 is a view partly in front elevation and partly in vertical cross-section on the line 2-2 of Fig. 1. 1

The same reference numerals are applied to corresponding parts in these two views.

Referring to the drawing, the reference numeral 3 designates a drum type table, which, in accordance with my invention, has a circular sewing compartment 4 provided `in the top portion thereof between the circular table top 5 and a circular bottom wall E, the top 5 and bottom E being joined together in fixed spaced relation by an arcuate wall 'I which encloses the rear half of the compartment. Depending from the bottom 6 is a circular ornamental apron 8 of any suitable or preferred design, and a supporting base of any suitable or preferred design is provided joined to the bottom 6 within this apron, a portion of one leg of this base being indicated at 9, for example. Two arcuate doors Il)` and I I, each extending through 90, are provided to close, theopen front half I2 of the sewing compartment il.V Each'of these doors has lan operating knob I 3 extending radially outwardly from the front end portion thereof. Arcuate grooves I4 are provided in the top and

bottom walls

5 and 6 of the sewing compartment, and each door has three pairs of guide pins I5, I6, and I1 extending from the top and bottom edges thereof and arranged to slide in these grooves I4 toguide the door through approximately 90 of move- .ment from `the fully closed position to a fully opened position. The door I0 is indicatedin the fully closedposition and the door II in the fully opened position in Fig. 1. The pins of eachpalr are coaxially arranged, and thepins I5 are at the middle of each doorand serve as combination pivot and guide pins, the door being arranged to pivot about these pins as an axis as the front end ofthe door is pulled outwardly by means of the knob I3 at the commencement of the opening movement, at which time the pins Il, which` are provided at the rear end portion of the door, move inwardly in communicating grooves I8 into the arcuate grooves I4, the door being thereafter guided by pins,` I5 and II for sliding movement rearwardly in the sewing compartment in the space 4 between the back'wall "I and the circular tray I 9 that contains the sewing facilities.` The adjoining edges of the back wall 'I and the doors vIIJ and II are out on an. acute it is obvious that the finished outer sides of the' doors would be apt to get scurfed by"` rubbing contact with the back wall 1, and, for that reason, I have provided the intermediate"pairpf guide pins I6 spaced far enough rearwardly infrelation to the pins I to cooperate with pins I1 in guidin the socket by the disk 33 and extends freely through a center hole in the disk and through a registering bearing hole 36 in the bottom of the tray and has a working t in a blind bearing hole 3l provided in a wooden spool 38 that is preferably cemented to the top of the tray bottom. A hook-shaped pull member 39 is fastened to the front end of slide 30 and extends upwardly in .rontpf the.. tray where.it.can be. taken hold of J-ff easily 'to pullrout'i the tray 'when 'the fdoors I 0I l are opened, unless, of course, the operator prefers to take hold of the tray itself and pull the slide and tray assembly out that way. Any suit- `:fableor preferred means may be provided for .limiting the outward and inward movement of A"'slide 130, "as," for example, upwardly projecting ing the doors in the grooves I4, so that noos'cillation of the doors in relation to the grooves is -^pos`sible `at anywpointflinthewcourse. of .the-"formva'frd or rrearward?. sliding movement of/thefdoors. #Smooth sliding 1 operation 10i" the' doors throughhout itheirtravel 'invboth directionsfis-thereby positively assured The -pins iFI 6' necessitate Vthe :provision-cf only: small 'notches S2 I1 .in -.the outer side of grooves I4 near the front ends thereof, fasi shown in 'Figi 1L*13o-accommodate'these: pins in the closed fpo'sitionof the fdoors.
