Fig. 21 is-a perspective of the extension member 95.. shown in Fig. 15; and v Fig. 2 2 is a side elevation of the table shownin Fig. 15 in collapsed position.

In each of the embodiments herein shown for the purpose of illustration the table comprises 1.00 atop 26. two pairsv of legs 33-33 and 34-34, which may be pivotally secured to each otherintermediate their ends, as at 35, one of the pairs of legs 33-33 being pivotally secured to the table top, as at- 36. The table may beprovi'ded with a shelf 37. and if desired a drawer 32.

Such a table may be erected with the table top in horizontal position by placing. the upper ends of the legs 34-34 behind the abutment member 38. asshown in Fig. 1. The legs may be 111) locked in such position by means of the latch member 41 and the eye member 42. By providing a second abutment member 39 and a second eye member 43, the elevation of the table top may be raised, the table top still remaining in horizontal position. To increase the elevation, the upper ends of the legs 34-34 may be placed behind the abutment member 39, and the latch member 41 may be engaged with the eye member 43.

A table so constructed may be compactly col-' lapsed so that the legs and shelf lie substantially parallel to the top, as shown in Figs. 5, 12 and 22. In collapsing the table the legs 34-34 are swung about the pivot 35 in the direction of the large arrow in Fig. 1. The construction of such a table is described in detail in United States Letters Patent No. 1,961,241, dated June 5, 1934, and to which reference may be had for more specific instructions concerning construction of such a table.

The particular embodiment shown for the purposes of illustration in Figs. 1 to 5 inclusive, comprises an extension member 44 which is pivotally secured, as at 45-45, to the upper ends of the pair of legs 34-34, this pair being unconnected to the table top. Such a pivotal connection may be obtained by any suitable means such as a crosspiece 46, but there are other means which 30 will be apparent to persons skilled in the art of obtaining such a pivotal connection, and I do not limit my invention to the means disclosed.

, The extension member 44 comprises two or more members47-47 which may be reinforced by the crosspiece 48. It is necessary to provide member about the pivots 45-45 when the table is in erected tilted position.

For this purpose I provide a pair of spaced abutments 38 and 39, and a latch member 49. The front face of the abutment 39 cooperates with the rear face of the abutment 38 to prevent inward revolution of the extension member. The rear face of the abutment 38 cooperates with the latch member 49 to prevent outward revolution of the extension member. The latch member 49 may be placed upon the crosspiece 48 and may be operated to engage the eye member 50, or a latch member may be placed upon the under surface of the table top engaging either the crosspiece 48 or means upon the members 47-47.

By providing other pairs of spaced abutments, such as 40-39, and other eye members, such as 51, the angle or elevation of the table top may be increased at the desire of the user.

Other means for locking the extension member in extended position may be provided, such as the releasable means shown as the pins 52-52 illustrated in Figs. 8 to 14 inclusive. By providing holes 58-58 through the legs 34-34 and corresponding holes 53-53 in the members 47-47 to receive pins such as 52-52, the pins may be inserted in such holes to prevent rotation of the members 47-47 about their pivots 45-45 in either direction as shown in Fig. 4.

By providing additional holes, such as 54-54 in the members 47-47, the members may be releasably locked in a position adjacent the respective legs 84 when the members are retracted or when the table is in collapsed position.

The function of the abutment members 38, 39, 40 etc., may be accomplished by recesses in the under side of the table top, and I do not limit my invention to the specific means which I have disclosed. The crosspiece 48 may be eliminated, since the members 47-47 may function independently of said crosspiece.

By providing releasable locking means, such as pins 52 and corresponding holes (see Fig. 4), the latch member may be eliminated and only one abutment, such as 38, is necessary to prevent outward rotation of the legs 34-34 about the pivots 35-35. Releasable locking means may be used in combination with a latch member, since the latch member may function to prevent rotation of the legs 34-34 about the pivots 35-35, thus eliminating the necessity of any abutments. A latch member may be used alone with neither abutments nor releasable locking means.

The particular embodiment of my tilting device'illustrated in Figs. 8 to 14 inclusive, comprises extension members 55-55 which are pivotally secured to the lower ends of the respective legs of the pair of legs 34-34. I have obtained such a pivotal connection by means of the crosspiece 56, but. there are other means apparent to persons skilled in the art, of obtaining such a pivotal connection. Although I have shown no crosspiece between the outer ends of the extension members 55-55, a crosspiece may be used for reinforcement similar to the crosspiece 48 shown in Fig. 4.

It is necessary to provide releasable means for looking or firmly holding theextension member or members in extended position i. e. to restrain both outward and inward revolution of the members about the pivots 57-57 when the table is in erected tilted position. For this purpose I provide such releasable means for looking as the pins 52-52. By providing holes 58-58 through the legs 34-34, and corresponding holes 53-53 in the members 55-55, the pins 52-52 may be inserted in said holes to prevent rotation of the extension members in either direction.

By providing additional holes in the extension members, such as 59 and 60, the extension members may be locked in a plurality of extended positions, as shown by the dot and the dot-dash positions in Fig. 10, thereby permitting variation of the angle from horizontal at which the table top may be tilted.

By providing the additional holes 54-54 in the extension members, the members may be releasably locked in a position adjacent the respective legs 34-34 when the extension members are not in use, or when the table is collapsed, as shown in Figs. 8, 9 and 12.

The pins 52-52 may be attached to the legs 34-34 by means of chains 62-62 or other devices, to prevent loss of the pins.

The particular embodiment of my tilting device shown for the purpose of illustration in Figs. 15 to 22 inclusive, comprises an extension member 63 which may be made of strong wire. The arms 64-64 of the extension member must be sufiiciently resilient to resume a substantially parallel position after they have been moved inwardly towards each other a short distance.

The arms 64-64 are provided with lateral projections 67-67 which freely in the holes 65-65 in the legs. The resiliency of the material of the arms of the extension member allows the arms 64-64 to be moved inwardly, and thus allows the projections 67-67 to be Withdrawn from the holes 65-65.

The holes 65-65 cooperate with the projections 67-67 to provide pivots about which the exten- .1 not in use.

lining 68 may be providedfor the'holes'toresist the wearing action of the projections in the holes and to insure a permanent fit.

A plurality of pairs of holes, such as ,85 and 66- 66, may be provided. to receive saidproje'ctions allowing the extension member to be selectively positioned beyond the end of the legs 34-34 and thus allowing the table top to be tilted in a corresponding plurality of angles from horizontal.

The arms 646 i of the extension member-may be provided with a pair ofdepressions, such as Gil-+69, which are adapted to snugly; engage the crosspiece 58 when the extension member. is in extended position. Thecrosspiece 56 cooperates with the pair of depressions to restrain the extension member from outward revolution about the pivots 65--65 when the table is in erected tilted position. The depressions such as 69-69 serve to distribute the pressure exerted by the crosspiece upon the outsidesurface of the arms 6445i, and to minimize the tendency of such pressure to bend the arms.

A plurality of pairs of depressions may be formed to' correspond with the additional pairs of holes, such as 66-66.

One or both of the legs 34 34 may be provided, with a clip adapted to releasably hold the extension'member in retracted position when The extension member may be provided with bends, such as 71-+7l, which tend to prevent sliding of the table upon the surface of the floor, and which have other functions apparent to persons; skilled in the art.

' In operation the extension member is released from the clip andrevolved in the direction of the arrow in Fig. ,15to; extended position. as shown in Figs. 17 and 18. In extended position the crosspiece 55 prevents outward rotation of 1 the extension member, andpressure upon. the

top of the table prevents inward rotation.

Means other than the crosspiece-56 may be used to engage the arms of the extension member,.and thereby prevent outward rotation. The

bends, such as 69 -69 and 717l may be eliminated entirely or altered without departing from my invention.

It is apparent that when the tilting operation.

is secured by raising the lower ends of one pair of legs. it may be accomplished by placing .an

extension member or members upon either pair of legs, and althoughl have illustrated extension members only upon he inner pair oflegs. 34 34,. my extension members may be utilized instead upon the other pair of legs 3333-if desired. On

the other hand, when the tilting operation issecured by extending the upper ends of one pair of legs, it must be accomplished by extending the pair of legs whichis not already secured-to the table top.

In a collapsible table similar to the one illustrated in the drawings I recommend placing; the

extension member or members upon the inner.

pair of legs corresponding to the legs-3434.- since by so positioning the extension member the table may be more completely collapsed.

' In a table which is adapted to be used with its top either in a horizontal position or in a tilted position, it is desirable to have a retaining'rail for the table top whichmay be used, desired, with the top in tilted position or otherwise. and which may be lowered to a position in which its upper edge is flush with or below the upper plane of the table top. a

The embodiment of my adjustable retaining rail shownior the purposes of illustration in Figs. 1 to 3 inclusive and Figs. 5 to 7 inclusive, comprisesa longitudinal member 25' which may be secured to; the table top. 26 with screws. 272 7, which, pass through the vertical slots 28-28 in the member 25.

. The outer face of the member 25. may be pro-.- tected from the heads of the screws 27-27 by the use of washers 29-29.

- The vertical slots 28.28 may have connecting therewith one or more pairs of horizontal chan:- nels, such as,3030 and 3l31.

The member 25 may be constructed of a width. greaterthan the thickness of the table top 26,

so that when the upper edge of the member 25 is flush with or below the upper surface of the table top, the lower edge of the member will extend below the top of the drawer 32 and act. as, a retaining stop for said drawer.

By providing the horizontal channels 30-30',

when the member 25 is moved upward to full raised position, as shown in the dash. position in Fig. 6, by sliding the member 25 to the right, the sections of the screws 2727 which are coincident with the slots 2828 will rest, in the horizontal channels 3030, and the member 25 will be releasably locked against vertical displacement in'full raisedposition, where it provides a retaining rail for the table top and. allows the drawer to be Withdrawn.

A second pair of horizontal channels. 31-31. may be provided so that when the member 25 is moved upward to an intermediate position, as shown by the dot double dash position in Fig. 6, by sliding the member 25 to the left, thesections of the screws which are coincident with the vertical slots will restin the horizontal, channels 31-31 and the member 25 will be locked against vertical displacement in intermedate. position, where it providesboth a retaining rail for the table top and a retaining stop for the drawer.

When the table top is tilted there is atendency for the drawer to slide open, and said interme-v diate position of the member 25 allows it to function to hold the drawer shut and to form a re- I- taining rail for the table top in the same position.

,One of the important functions of the member 25 in a collapsible table is holding the drawer against withdrawal by gravity, because when the table is in collapsed position the drawer will frequently be in a vertical position It should be understood that the member 25 will serve all of the functions above outlined without providing either or both of the channels 30--30 and 31-31,, and I do not limit my invention to the provision ofsuch channels. The channels 30-30 and 3131 may both be'placed on the same side of the vertical slots 28-28 or may be staggered on either side as I have shown them in the drawings. channels may be provided adjacent the top ofthe vertical slots 2828 to lock the member 25 in lowered position if desired.

An additional pair of A collapsible table or like device constructed in V when not in use as a retaining rail, or which may s function as both a retaiing rail and a drawer stop at the same time.

It should be understood that the present disclosure is for the purpose of illustration only, and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
