INVALID-TABLE To all whom it may concern Be it known that I, J OHN- PERRON,- a 01131- zen ofthe United States,- residing at Salem;

in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in- Invalid-Tables, of which the following is a specification.

My invention relates to table constructions and has particularly to do with that type of table generally known as an invalid table or bed table.

The object of my invention is to provide a novel arrangement whereby the folding legs of the table may be positively locked in extendedand folded positions, and thetable itself as well, as its extension leaf may be adjusted to any angle desired. It is'an additional object of my invention to provide a meansforsupporting the leaf of the table in adjusted position, the adjustment being controlled by a means convenientlylocated at the front of the table within reach of the patient.

.These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to' be hereinafter specifically described and claimed. Reference will now be had to the accompanyingdrawings forming a part of this specification, wherein:

Figure 1 is a perspective view of my table. Fig.2 is an end elevation, the dotted lines showing the leaf support and. the leaf in horizontal adjustment.

Fig.3 .is a front elevation. Fig. 4 is a bottom view of the table in folded position. v Fig. 5 is a detailed view of the leg extension means.

' Throughout the following detailed description and on theseveral figures of the .drawings, similar parts are referred to by like reference characters:

The table proper is represented by the letter A and comprises the usual fiat bed. Hingeably connected to the under side of the bed arelegs 6. 7

Intermediate said legs 6 which diverge,

the back members being inclined outwardly for purposes to become apparent hereafter is a cross member 7. The legs are arranged to fold lnwardly I and cleats-8 pivotally connected to the unl Specification of Letters Patent. :I 3fi; 3 1 1 Dee, 27,1921 Application filed January s1, 192,1. --Scrial No: 441,376.

derside-of the table' 'bed are arranged a swing over the folded legs to hold themi11 folded position;- When extended the freeend of said cleats-8 engage the supports- '7 whereby the leg members are rigidly locked;

Upon theba'ck legs are arranged extension members 9 bestshown'in -Fig.--5.- These members comprise fiat'pieces pivotally con-,- nected at 10 to the table legs.6,-unequally distant from the opposite ends of the memher 9. Equi-distant, and upon opposite sides of the pivotal connection--10 the extension members are apertured as indicated-by'the ordinal 11.; A projecting pin12 is carried bythelegs 6 and arranged so that when the member 9 is either in extended position-or in folded position it will engageiin one ofthe apertures 11 to hold ment. For the urpose ofi' expediting ;a change from folc ed: to extended-position or vice versa', the ends ofthe extension member 9 are lVhether the extension members are metal or wood is immaterial but the connective it against displace preferably curved outwardly,

means 10 should hold said member in fricjusted posltion. 1

It willbenoted that when the legs are in tional engagement with the leg when'in adfolded position-the free end of the back legs Each of the book holders 14 shown maybe positioned at any convenient points upon the leaf and may comprise spring members pivotally connected at one end and having their free ends leaf. I I

The hinge connections of the leaf admit of the latter being folded over and upon-the in frictional engagement with the table bed when not in use.- A. leaf supporting member 15 comprising an armpivotally connected at 16 to the rear legs 6 of thetable will support the tableleaf B in horizontal alinementto the table bed when thelonger end of said leaf supporting member 15 engages the under side of the table bed, as best shown in the dotted lines in Fig. 2.-

this

means the upper flat surface of the table bed may be increased to include the entire surface of the leaf B. 7

Anumber of notches 17 are arranged upon the front leg 6 of the table so that when the longer end of the support 15, which end may for purposes of convenience project beyond the edge of the table, is pushed downwardly, it will engage therewith and be held against upward displacement. The other end of the support 15 which engages the under side of the leaf D will of course be moved upwardly causing the leaf B to be inclined with respect to the table bed, the limit of the inclination being controlled by the number of notches 17. To release the leaf or to return the leaf 17 to horizontal position or to a less sharply inclined position the free end of the member 16 is lifted outwardly and raised to the desired adjustment. The weight of the leaf B of course will cause it to follow and keep in engagement with the other end of the suport 15. Under no condition, however, can the leaf be inclined below the horizontal because of the engagement of the longer end of .15 with the under side of the table bed when such adjustment is reached. While only one leaf supporting member is shown, another could be arranged at the other end of the table.

- When the table is folded the leaf support member 15 being carried thereby is folded therewith and protected from damage, as is shown in Fig. 4:, because its movements are limited by its engagement with the oppositely disposed rear table leg 6.

The table may be provided as shown in several views with a clamping member 18 for holding papers and other objects against displacement. The outward inclination of the rear table leg lends greater support and particularly when weights are carried by the leaf in horizontal adjustment to the table top. 7 o

In operation the table is placed over the body of the patient and upon top of the covers, thus not interfering in any way with their protection. T he position of the table is to be regulated by the patients wishes and whether reclined or in sitting posture. lVhether the leaf B will be in horizontal adjustment or inclined at an angle to the t ble bed is for the patient to determine and is controlled by his manipulation of the support 15. If it is desirable to tilt the table bed proper the leg extension members 9 are swung from folded position into extended position and there held by engagement of one of theapertures 11 with the pin 12.

' While I have thus described and illustrated an embodiment of my invention, there is no intention to be limited thereto as modifications, changes and alterations within the scope of the claims hereinafter hereto appended are to be resorted to when desired.

What I claim as new and desire to secure by Letters Patent of the United States is- 1. In a table structure, a body, and foldable legs, said legs being adapted to fold into engagement with each other to form complemental handle members whereby to provide handle means for carrying said table.

' 2. In a table structure, a body and foldable legs, said leg-s being inclined outwardly from an edge of the body when in folded position to intersect and provide carrying means for the table 3. A table comprising a body, legs at 0pposite ends of the body, a leaf at one side thereof, and an adjustable leaf support pivoted intermediate its length on one leg, one end thereof being engageable with the leaf, and means with which the other end is adjustably engageable for maintaining the support in adjusted position. 7

4. A table comprising a body, legs at opposite ends of the body, a leaf at one side thereof, and an adjustable leaf support carried by one leg and in engagement with another of said legs for maintaining the support in adjusted position.

5. A leaf support for a table having a top and legs, comprising a movable member connected to one of said legs and having an extension arm engageable with the top of the table to hold the leaf in one position, said arm engaging with the second of the table legs to holdthe leaf in another position.

6. A folding table comprising a body, folding end members comprising legs and an intermediate cross piece, and a leaf foldable over said body, one of said end members being provided with a leaf support upon one end of which said leaf rests, the other end thereof engaging along the under surface of the body to delimit movement of the leaf.

7. A folding table comprising a body, end members comprising pairs of hinged and diverging legs and an intermediate cross piece, a leaf foldable over said body, and an adjustable leaf support carried by one of the legs of said members, said support comprising a leaf engaging portion and an extension arm engageable with the other leg of said member to prevent inclination of the leaf beyond a predetermined angle.

8. Ar folding table comprising a body, hinged legs at opposite ends of the body and foldable thereunder, the legs at one side being inclined outwardly and arranged to cooperate with one anotherfto form table carrying means, a leaf foldable' over said body, an adjustable support for said leaf disposed at one endthereof and carried by one of the table legs, means carried by another of said legs to releasably lock said horizontal, and independent and oppositely gagement with the leaf, the other end of disposed pivoted brace means engaging said said support resting upon said bed when 10 legs when in extended position, said brace said leaf is in one position, and means for means being shiftable to form positive lockreleasably locking the support to hold the 5 ing means for the legs when in folded posileaf in other positions.
