I This invention relates to typewriter de'sks,

the primary object of the inventionb'eing to provide a typewriter deskin which the typ'ewriter supporting platform" when lowered andin enclosedi pos'itionis in the-rear po'rtion of the desk structure so that ample knee space and "legroom 'is pr'ovidedjunder the "Ajfur ther object ist'o'fprovide a desk? 7 I ushown at 9. The pivotal connection/9 is great fault with desks long in common useis that the typewriter supporting plat form'when'in its lowered position'islocated' so that very 'sm all spa'ce' is allowed for the legs. of the i'iser of;the desk, and this not )nly results inid'isc omfort to the user but reconstant'contacttherewith;

which enables the" desk-to be easily [and quickly manipulated securely held either of its extreme positions of-mampula- 1 pear;

the latter is in its closed or horizoritalpost tion, as clearly lndicated in Figure 1.

theparts as willfmore'fully hereinaftertap- I h The angle brackets 7. also function as supports for .thermovable' covereS *when'."

Thelonger ends of the links 8, are con-- nected to brackets 10 secured to the under face and forward portion iof'thelm ovable cover 3. The shorter ends ofthe links 8 are. piv.otally*connected by short links 11 with.

the forward portion of platform 5, "theconnection being preferably at theedges'ofthe 3 I i platform,'as indicated.

I The platform'h is also connected icy links 12 with fixed brackets 13 rigidly secured-to the fined portions of the desk 1.. These links 12 also connect to the side edges/of platform V 5 and near the rear or inner; end of said platform: Links 14 pivotally connect brackets '15 on the under face of movable cover 3 w1th-p1vots16 connected to bars "17 ,or

other fixed parts of the desk 1.

I would call particular attention tofthe construction of the links 8 and 11. he noted that the shorter'end of link 8ex- It will I tends beyond the pivotal connection 9 between said link'8a nd thelink-ll, and that i this endof the link 8 is provided with. a laterally projecting pin or hip; 18 which is when said links are moved into substantial ahnement, as ndica'ted in Figure 4,' and limit adapte-dtorengage in arecess 19 in link 11 r horizontal position, as shown in Figure 4:,'

there will be no tendency to the downward movement of said platform.

"Figure 4. It is of course to be understood The operation is as follows: Figure 2 illustrates the cover 3 in horizontal position so that it constitutes a part of the desk top. This view also illustrates the platform 5 in its enclosed position, and it will be noted'that when in this position the ",tance'from the front of the desk 1 so that platform 5 is disposed an appreciable disthere is ample leg room for the user of the desk. TlllSPOSltlOlllHg of the platform is due to the arrangement .of linkage which has been described and theoperation of which will now be explained] To bring the plat form 5 from the position shown in Figure 2 to that shown in Figure 4c, the operation is as follows: The front end of the :cover 3 is forced upwardly and rearwardly. This rection or path of this movement of the platform 5 is controlled'iby the swinging movement of the links 12. Toreturn the pat-form 5' to its lowered and inwardposition the cover 3 is drawn upwardly, impartin movement to the links 8 and ll-to swin b b theplatform 5 to the position shown in that the several links are arranged in dif ferent planes so that they do not engage each other 1n a manner which would lnterfere with the operation above described, and

this is illustratedin Figure-3 of the drawing..

ario'us slight changes and alterations might bem-ade-in the general form of the parts described without departing from the invention and hence I'd'o not limit myself to the precise details set forth but consider myself {at liberty to make such slight changes and alterations asefairly fall within the spirit and scope of the appended claim;

I claim: r a

The -.com.bination' with a'desk having an opening in its top, a cover normally located in said opening and a typewriter supporting platform normally below the cover, of levers pivotally connected between their ends to fixed partsof the desk, and at their upper ends pivotally connected to the forward portions of the cover, said levers at their lower ends connected links with the forw-ard portions of the platform, links connecting the rear portions of the vplatform with fixed parts of the desk below the normal position of the platform, and other links connecting the rear portions of the cover with fired portions of the desk below the normal position of the platform.
