hhd d dhd DRAW TABLE.

Application filed March 13, 1922 Serial No. 543,180.

This invention relates to improvements in draw I tables.

The objects of the invention are:

First, to provide an improved draw table in which the parts of the top are effectively maintained in separated relation while the leaves are being withdrawn or pushed in.

Second, to provide an improved sliding means for such structure.

Third, to provide an improved lock means for the parts.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devicesand means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention isclearly illustrated in the accompanying drawings, forming a part of this specification, in which:

Fig; I is a sideelevation view of the upper part of a draw table embodying the features of my invention.

Fig. 11 is an end view of the same.

Fig. III is a side elevation view of the right hand portion of the table appearing in Fig. 1 showing the leaves and slide. partially withdrawn and indicating by dotted lines the relation of the parts when the table is extended.

Fig. IV is a detail longitudinal vertical central sectional elevation view taken on a line corresponding to line H of Figs. V and X. a

Fig. V is a detail plan view of the right hand portion of the table appearing in Fig. I with the leaves drawn out, the left-hand portion being broken away and the table top being partially broken away and removed to show details of construct-ion.

Fig. V1 is an enlarged detail sectional view on a line 6-6 of Fig. V showing particularly details of the slide and its auto matic top support extension with the leaf and slide in extended position.

Fig. VII is a similar sectionalview show ing the relation of the parts when the table is in closed position.

Fig. VIII is an enlarg d de ail s tional view taken on a line 8+8 of' Fi-gs. I, IV, V, VI, V I, IX d showing the retai "12g means for the top.

Fig. is an enlarged d tail sle' tiqna i View taken on. a'linecrrep pendi-ligt line 9 9' of Figs. v. and VIII. and X, showing the said top retaining means.

Fig. X is a detail inverted reduced plan view of the table topshowing the position of the slide contact buttons and the top retaining and locking means- In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of thesection lines.

The numbered parts of the drawing will he considered by their numerals; are the side rails of the table. 2 are the corner posts. 3 are the end rails. 4 is the central cross bar between the side rails being notched at 5 near each end as seeninFig. VII.

6 is the table top. 7. is the central cross supporting cleat of the said tabletop. 8 are the fastening means for retaining the table top in central position. Each is provided with a downwardly extending arm 9 just within the corresponding side rail 1 having the longitudinal keyhole slot 10 through which extends the bolt 11 provided with a retaining nut 11" on its inner end as seen in detail in Figs. VIII and IX. A dowel pin 12 is secured to the top cross cleat near each end and projects down from the under side of the said cross cleat 'Z and engages a'djustably in' the hole 13 for partial withdrawal therefromin the side rail 1. These parts co-operate.. The dowel alone cannot be efiectively retained and the slotted arm with pin in slot will not play freely if made a close fit to guide the parts.

' 1'4: and 15 are the extension draw leaves disposed under the ends of the table top 6 when the table is in closed position as indicated in Figsl and IV. 16 and 17 are the cross cleats und'er the outer ends of the leaves 14 and 15 respectively. 18 and 19 are oppositely disposed pairs of slides which i are secured to the under sides of their respective. leaves 14 and '15 and travel in notches 18 and '19 in the end rails, the same r ding 1111 .11 h bot m f the S d notches- The' undersidesofthese/slides are inclined so that as the slides are drawn out the rerecti e e vesle and .1 ar ie h e y ilt' e grad a ly ais d' o the p i ndicated by t dotte l n s n g- 11- T innelre'nd of ch slid i 1 11 n a a 1 8 and '19" to receive the cross cleat 7 h n the lea es a e d a n out The inner ends are provided ith st re 2.0 ha ing adown into place.

gaging-hooks, 21 to pass under the central bar a and engage in the notches 5 of the cross bar 4, the said stops being retained in place by screws 22; j

An automatic slidable support block 23 for the table top is disposed and slides in the recess 25 inthe upper side of each slide as seen in Figs VI and VII. 'This auxiliary slide block 23 is rounded at 24 on its inner end. A stop pin 27 is disposed to limit the inward movement of each block. A stop block 23 limits the outward movement.

A pin 230 in slot 231 in the block 23 guides and retains the same in the slot 25. A plunger 232 comprising a wire nail with a large head reacts against spring 233 disposed in the bore or socket 234 in the block 23 and shoots the auxiliary slide 23 out against the stop 27 whenever it is disengaged from the sliding parts.

Slide contact buttons 28 suitably rounded on their contact surfaces are placed on the under side of the cross cleat 7 in position to contact with the upper sides of the slides and support the table top out of contact with the leaves, while the same are being moved out and in. This prevents injury to the tops of the draw leaves. /Vhen the slides are pulled out to the limit as indicated in Fig. VII these buttons drop into recesses 29 formed in the tops of the slides, which per: mits the top 6 to drop down directly into contact with the draw leaves when same are pushed in. The contact buttons 28 rest upon the top of the slide 23 when the draw leaf is being drawn out and contacts with the extension block 23, thus supportingthe table top entirely out of contact with the leaf until it is entirely withdrawn from beneath the top. When the leaf reaches its outermost position the weight of the top on the rounded portion 24; causes block 23 to move automatically from beneath the contactbuttons 28 and permits the top to drop Slight clearance is provided for and the leaves can then be closed up to the top. When the draw leaves are being pushed in, the table top is, of course, raised. The slide block 23 is carried out to place by the spring 233 and the antition with the table framework of a to with i central cross cleat thereunder, downwardly projecting contact buttons disposed upon the under side of the central cross oleat in position to ride upon the upper. sides of the draw leaf slides, a cross bar in the center mosses of the table, draw leaves adapted to be disposed underneath each end of the said table top, slides with inclined surfaces riding i notches in the table ends and secured to the,

said draw leaves, having cutaway portions on their upper sides at the inner ends to accommodate the central cleat and provided with longitudinal ways in their upper surfaces at the beginning of the cutaway part and notches on their upper sides in proXimity to the draw leaves to receive said contact buttons, a horizontally movable slideextension, having rounded inner upperv end, disposed in the way in the top of each slide in proximity to the cutaway portion adapted 89 to automatically retract when the leaves are fully drawn to permit the central cleat and table top to drop to position when the leaves are withdrawn, spring means to hold said extension slide yieldingly in position, and 55 hooked stops at the inner ends of said slides 'to engage said cross bar, coacting as specified. p
