AUTOMOBILE TABLE Filed Nov. 13, 1931 2 Sheets-Sheet 2 I I W ATTORNEY Patented Feb. 14, 1933 UNITED STATES PATENT F'FFCE BERNARD I. BAUS, F \VACO, TEXAS AUTOIVIOBILE TABLE This invention relates to automobile tables and aims, among other objects, to provide an improved table of this type which may readily be adjusted as to length and height and which may be folded when not in use.

In the drawings showing a preferred embodiment of the invention:

Fig. 1 is a side elevation of the improved table shown supported on the doors of an automobile;

Fig. 2 is a top plan of the same but showing one of the doors partially open;

Fig. 3 is a bottom plan view of the table in folded position;

Fig. 4 is a sectional view taken on line 4t of Fig. 3 and shown on alarger scale;

Fig. 5 is an end elevation of the table in open position and shown on the same scale as Fig. -l; a

Fig. 6 is a vertical longitudinal section 0 one end of the table in open position; and

Fig. 7 is a view similar to Fi 6 but showing the table in folded position.

Referring particularly to the drawings, the improved table is there shown constructed and arranged to be supported on the window ledges of automobile doors or windows and is especially adapted for use in connection with sandwich shops having curb service. Various tables have been heretofore proposed for open car use but such tables could readily not be used with closed cars, especially in in clement weather when the car windows are closed. In the present car, the table may be placed in position in a closed car by an attendant while the door is open and the door may then be closed with the table supported thereon. The invention also has other advantages as will appear later.

Referring to Figs. 1, 2 and 3, the improved table is there shown as comprising a rectangular tray portion 10 conveniently made of wood and having a marginal rim 11 to prevent dishes and tumblers from slipping off the edge. A relatively wide and shallow channel 12 (Fig. 4) is formed longitudinally of the tray in the bottom thereof and guard members 13 are secured to the bottom and overhang the channel to form a trackway for extension members 1d slidably mounted in the channel. The inner ends of the extension or slide members 1e abut when the table is folded, as shown in Fig. 3, and their combined length is less than the length of the tray so that portions of supporting members to be described may be located in the channel 12 at its ends when the table is folded. The outer end of the slides 14 are bifurcated to receive the hubs 15 of supporting members 16 which are journalled on transverse pivot pins 17. Hanger members 18 are connected to the outer ends of the supporting members and are adapted to engage the window ledges or the side edges of a car to support the tray in horizontal position (see Figs. 5 and 6).

The supporting members 16 are adjustable in length so that the table may be accommodated to the car, and are each shown as comprising a non-circular post 19 telescoped within a non-circular tube 20 which is rigidly secured at its lower end to an extension 21 on the hub member 15. See Figs. 6 and 7. The post 19 is adjustably secured to the tube 20 by means of a button or projection 22 on the free end of a flat spring 23 projecting through one of a plurality of apertures 24 in one wall of the tube. The other end of spring 23 is removably secured in a slot 23 in the post near its lower end. To provide room for the spring to be depressed to disengage the button from an aperture, the post is recessed, as shown at 25. To facilitate adjustment of the post, an expansile coiled spring 26 is interposed between the lower end of the post and the extension 21, so that when the button 22 is depressed, the spring 26 expands and moves the post outwardly so that it may then be grasped with i the same hand and moved to the next position. Otherwise, two hands would he needed to adjust each post, one to push the button and the other to move the post.

The hangers 18 are shown as being substantially U-shaped, each comprising spaced arms 27, connected at their rear ends by a cross bar 28 which normally extends parallel to the pivot pin 17. The arms 27, which are adapted to rest on the window ledge, have depending tongues 27 formed on the front ends adapted to extend downwardly into the space The outer end of each post "19has a circular portion 29 and" the intermediate portion 0 each crossbar is enlarged to form afhub 30 havinga bore to receive the circular portion 29. .The hangers are each-held innormai po sition relative tothe posts bymeansof a pin 31 extending transversely through the circular portion 29 v and engaging a 5 notch 32 formed at-the apex of cam surfaces-33 M the lower end'of the hub 30.- lhe notch is held in engagement with the pin byanexp'a'nsile coiled spring 34=surroundmg a reducedpor- -y s v p'os-1t1on,-the door at either side may be opened tion' 35 on, the post and extending between hQ hub BQ and 1 a nutf36 on? thegportion 35. B'y this arrangement the "hangers may. be

partially rotateclon thejposts, but the springs forcingthecamfisurfaces against the pins,

will restore them tonormalposition. V

' To holdnthe supports- 20 at substantially right, angles to the slides when in open position so that they will in} effect "be rigid on the extensions lyeach hub. member 15 is provided with a depending tail piece or extension :37,- adapted 1 tobe engaged at its lowerbeveled end by a flat spring 38 having a-be'nt outier, end providing a shoulder 39 which limitsthe swinging movement of the support to 90; .The inner. end of the spring is rigidly securedtothe 'bottom of the slide and a lug LO- on the spring near the shoulder39lengages the rear of thetail piece endsof the springslare depressech'and the tail pieces 37, are swung inwardly and rip-,-

. 37. to. prevent the support fromnfolding aceidentally. i z

When the tableiis to be vfolded, the outer to accommodate the tailpieces and wings 42 formedon' the tail piecesengage in recesses A3 [on opposite sides ofthe slot 41 to hold thelposts in substantially "hOIlZOHtEIl alinementwith the slides when theyare folded. When: the posts have been folded, the slides and posts may be pushed beneath the tray until proj ections 44, formed on the; cross bars '28 engage the ends of the tray. Flat springs viisecured to the bottom of the tray at the end frictionall-y engage the pro1ections 44 whenthe table is folded'to prevent outward movement of the slides until isis desired to unfold thetable. l .7 s

{In order that the slides may bemoved freely, their inner ends are provided with rollers 46 which engage the bottom ofthe channel. and the, guardi nembersor tracks 13. other rollers At? carried by'the ends of 48 at therear ends of the slides prevent them from being pulledout of the channelby strikingf against 1 stop shoulders $9 on ;the tracks When thetableis to-'be-.open'ed, .the cross bars 28 are grasped andz pulled outwardly until the hubs 15 are clear of the ends of thetray}; The posts may then be swung upward ly until the shoulders 39 engage the endsof door and thehanger on the opposite end of theltable may be engaged with the window ledge ofthe adjacent closed door. The slide on the near end of the tableis' then pulled out-Vandthe hanger rotated on the post un tilit isparallel with the open door andit may, then'be engaged with the window ledge and the door closed.
