T N am FRANK LEWIS HARRISON, or cooenn; nnw soU'rHweLns nnstrnenie' :onor-nown TABLE on SEAT Application filed. January 7, 1931, Serial .No. 507,090, andin Australia I Femmary-20," 1930.

The invention relates to the class of tables,

seats, and articles of similar character which -whereby-it passes into-the recessesin the W brackets. t i

; E. Pivot pintis fixed in bracket 6 andtu-rns 55 when not required foruse may be turned from a horizontal to a vertlcal pos1t1on.

According to my invention the board used as a table or the like is pivoted upon pivot; pins passing through brackets which are located one at each side of one end of the 3 board and fixed to a support.

When the board is out of'use it hangs approximately vertically from the pivot pins.

When turned upwardly to bring it into use the board moves laterally under influence of a spring and its respective corners pass into recesses in the sides of the brackets by which it is maintained in horizontal position.

The springreferred to is of the spiral coil type, and is sleeved upon one of the pivot it coincides withthe angleof an enlarged portion ofthe recess shown in Fig. 2. It will 70 then clearthestop and whenreturned'to th pins and received in a recess in the board. The board is notched at one cornerto permit it to move laterally in one direction;

A stop projecting from one bracket prevents accidental lateral movement of the;

board which may also be locked in the bracket by a thumb screw.

I will now describe my invention in detail by reference to. the accompanying drawing wherein Fig. 1 is a perspective view.

Fig. 2 a fractional end elevation and Fig. 3 a corresponding fractional'plan. Fig. 4 a fractional plan illustrating a modification.

The board 1 has metal reinforcing strips 2-2 upon each side and when out of use is suspended (as indicatedin dotted lines Fig. 2) from pivot pins 3 and 4 passing through and projecting beyond the respective brack- 4 ets 5 and 6 which are fixed to a support.

bracket 5 and permit of lateral movement of the board.

In the corresponding faces of each bracket is a recess 8 and the board is maintained in its horizontal position by passing it laterally into these recesses.

Pivot pin 3 passes into a groove 9 in the board and has sleeved upon it a spiral spring 10 which, being compressed between adjusting nuts 1112 upon the end ofthe pin and must first be 7 stop.

The board is notched out at 7 to receive 1 the inner faoe'ofthe-bi'acket, moves the boai'd laterally when in its horizontalposition in 35 11016 in theedge of the board.-,

' A cover plate 13 fixed'by screws lit-to the board'covers groove 9 in which pin3-is 10- cated and gives access 'tothe adjusting nuts 11-12,by-which pressureof the spring is 7 out of the recesses astop 15=-projects from bracket 5 acrossthe'path' of the board,and

to enable the board to ,clearthis stop when beingraised to its horizontal position itis first turned a little above the horizontal until horizontal will pass into. the recesses.

. Before the board can be moved laterally it turned upwardly; to clear the As an additional'precautiona set pin 16' can be screwed through bracket 5 upon the top of the board to lock it in position.

In themodification shownin Fig. 4, the

spring is located upon the right-handside 0t the board and being sleeved upon trunnionpin 4 is compressed between adjusting nuts 17 and the face of bracket 6.: j I i it The bracket has a cylindrical projection 18 encasing the trunnion pin and spring- The action in this case, is similar to that? previously described the spring moving the board laterally when it is horizontal and causing it to enter recesses in the brackets. I claim: s 1. For the purpose indicated in combina' tion a board, pins upon whichthe board is pivoted, brackets carrying the pivot pins and each recessed to receive the board when moved laterally, spring means tending to move the board laterally intothe recesses and a stop upon. one bracket projecting over an gnfarged part of the recess therein as,speci--' e'. Y I a.

2. For the purpose indicated in combina 100 bracket upon Which theboard is pivoted and tion, aboard adapted to serve as a table or the like, brackets located at opposite corners of the inner edge thereof, a pin fixed in each slidable, the brackets each having a recess adapted to receive one of thecorners of the board when it ismovedlaterallmdhe board being notched'at one corner to permit the lat eral movement, and a spiral compression spring sleeved upon one of the pins tending to move the board laterally, "as specified.

3. For the purpose indicated ,-in.combination a board adapted to serveas a table or the like, brackets .-locate.d one ateach corner of p theinner-edge thereof, a pin fixed in each bracket upon which theiboard is pivotedand slidablm the :brackets each having-a"-1recess to an. angle above the 'horlzontal, spring I on-e lo-racket adapted to lo'ear'npon the top of the bo ard to lockit in position,-as" specified.

4. For the purpose indicated in "combinationjaFboard a-dapted to serve-as "a table-or the like', brackets located one at eachcornerof j the-inneredge thereof,-a pin fixed in *each' bracket-upon Whichthe b'oard i's pivoted and w' slidab'le, the brackets 'eachhav ing a recess adapted to receive *a corner of the 'board,
