United States Patent Ofiice 2,849,534 Patented Aug. 26, 1958 SERVING TRAY SUPPORT FOR DRIVE-IN RESTAURANTS William Stoner Doyle, Fort Lauderdalc, Fla. Application December 1, 1955, Serial No. 550,355 4 Claims. (Cl. 1'791) This invention relates to a food or serving tray and utility support adapted for use in the well known drive-in restaurants and whereby food and drinks are served to the customers in the vehicle.

The invention consists generally in a supporting structure that is carried by a fixed ground standard or other support whereby the supporting structure may be swung in a horizontal plane toward and from the window of a vehicle that is disposed within a predetermined driving lane and whereby the supporting structure is capable of swinging away from the vehicle after use and thereby to permit the free and unobstructed movement of the vehicle to and from the driving lane.

The invention further contemplates a support for a tray that is swingable toward and from a vehicle whereby to move the device in close proximity to a window opening of the vehicle and with means being provided whereby the device may be easily adjustable vertically to accommodate itself to overlying relation to the sill of the vehicle window for convenient reach of the occupants of the vehicle.

The invention further contemplates a novel tray support having a rigid base plate that is swingable upon extension arms carried by a fixed standard and with the base plate supporting an overlying housing that comprises a flat bed surface for the resting support of a food 01' a food carrying tray and with the housing being provided with accessory cabinets and an audible speaker cabinet whereby the conventional napkins are housed against the weather and whereby the various condiments are likewise housed against the weather to be readily accessible to the occupants of the vehicle and with the audible speaker cabinet providing audible transmission of music whereby the occupants of the vehicle may be entertained during the use of the device, and wherein the device is adapted to be provided with a Z'Way well known communication system.

The invention further contemplates a novel panel carried by the housing whereon is disposed a signal switch and indicator and a volume control switch and whereby the occupants of the vehicle may indicate to the restaurant the desirability for service or the like and with the housing having its panel provided with a site opening wherein is displayed indicia corresponding to remotely reproduced musical compositions or the like.

A further novel feature of construction resides in a latch plate that is disposed at the forward end of the device and whereby the occupants of the vehicle may easily and quickly control the vertical movement of the support to accommodate it to the window opening.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being bad to the accompanying drawings wherein has been illustrated the preferred embodiments of the invention and wherein like characters of reference are employed to denote like parts throughout the several figures.

Figure 7 is a traverse section taken substantially on line 77 of Figure 1.

Referring specifically to the drawings, the numeral 5 designates a tray support as a whole, embodying a rectangular base plate 6 having its marginal edges bent to form a U-shaped channel '7. The marginal edges of the base plate is provided with a flexible strip 8 and with the strip 8 preferably being formed of rubber or the like whereby to protect the sill finish of a vehicle window opening when the device is engaged thereover. The base plate 6 is preferably formed of sheet metal and is reinforced against flexing around its marginal edges by the formation of the U-shaped channel. The base plate is further reinforced against flexing by a pair of rearwardly converging angle irons 9, that are preferably spot welded to the upper su face of the plate. Welded or otherwise connected tothe base plate 5 at its rear end and intermediate its width is a relatively thick block 10. The block lltl is apertured at ill for the support of a pivotal stud 12 that constitutes the point of swivel movement whereby the base plate and associated elements are shifted in a horizontal plane. The angle irons 9 at their rear ends are also preferably welded to the block lull, providing a very rigid means whereby the device is supported from a rearward pivotal point and maintained in substantially a horizontal plane. A channel member 13 is welded or otherwise rigidly connected to the base plate 6 and extends longitudinally of the base plate 6 centrally thereof and provides the mounting support for a trip lever in, that is pivotally supported intermediate its length as at 15, upon ears preferably struck upwardly from the member 13. The lever 14 at its forward end is provided with a lip 6 that overlies the tail end 17 of a latch plate The latch plate 18 is pivotally supported at it? upon the side walls of the channel member 13, as shown. The latch 18 is provided with an upstanding exposed head portion 20 that is provided with suitable indicia, such as press and that indicates to the user the object thereof.

The lever 1d at its rear extremity is provided with an adjustable threaded screw 21 that extends downwardly through an opening in the base plate for engagement with a trip ring 22, to be described. The stud 12 has threaded engagement within a cylindrical boss 23 carried by a rectangular housing The housing 24 is chambered at 25 for the reception of the ends of a pair of parallel bracket arms 26 and 27, that are pivotally supported within the chamber 25 through the medium of pins 28 The arm 26 at its forward end is provided with a plurality of ratchet teeth St for latching engagement with a dog Ell that is pivotally supported within the chamber 25 as at 32. The dog 31 is biased in a direction toward the teeth 3:) by a spring 31a and whereby the dog will be constantly urged into a ratchet engagement with the teeth The ring 22 is pivotally supported upon the head 24, as at 33 for vertical swinging movement and with the ring 22 being centrally apertured to fioatingly engage over the boss 23. The housing 24 is further apertured at 34 for the freely sliding reception of a release pin 35 that underlies the ring 22 at its upper end and has resting engagement at its lower end upon a shoulder 36 carried by the dog 31. Thus, when the lever 14 is rocked by the latch plate 18, the screw 21 will engage the upper surface of the ring 22, pressing the ring downwardly, forcing the pin 35 downwardly to rock the dog 31 upon its pin 32 and whereby to release the dog from the teeth 30, to thereby permit the raising and lowering of the base plate and associated elements in any degree of pivotal movement thereof. It will be apparent, that the use of arms 26 and 27, serves to maintain the tray support horizontal throughout its vertical adjustment. The bracket arms 26 and 2'7 at the opposite ends are pivotally connected as at 37 and 33 within a recess 39 formed within a swivel head The head 46 is bifurcated to engage a pin 41 carried by the forward end of a bracket arm 42. The bracket arm 42 is hingedly connected at 43 upon a fixed standard or other support 44 that is positioned adjacent a driving lane that denotes the position of parking for the vehicles to be serviced. The arms 26 and 27 are connected together by a spring 45 whereby to bias the arms and the head 42 and associated elements in an upward direction and whereby to counterbalance the weight of the support and a tray supported thereon. The base plate 6 and the associated mechanism including the head 24 are thus shiftable in a vertical plane through the medium of the arms 26 and 27 and the dog 31. it will thus be apparent, that with the device being in an uppermost position, pressure may be exerted upon its upper surface, causing the arms 26 and 27 to swing downwardly when the latch mechanism actuates the dog to a release position. Movement to an upper position merely requires that the operator lift upon the outer end of the base, causing the dog to ratchet over the teeth 30 where the mechanism Will be held against further downward movement by the dog. ing across the rear end of the base 6 is a relatively heavy upstanding plate 39. The plate 39 imparts additional rigidity to any lateral twisting of the base and provides a connecting means for a structure, to be described.

Disposed in overlying relation to the base 6 is a housing, denoted generally by the numeral 46. The housing 46 is formed of sheet metal and comprises a relatively wide flat bed 47 that constitutes the support for a food containing tray. The housing is provided with fiat side walls 48 that are inwardly bent along their longitudinal edges as at 49 and with the edges overlying the channel 7 to be flush therewith. The bed 47 at its forward end is downwardly inclined to form a panel 50. The panel 50 is provided with a site opening 51, wherein is disposed a chart having indicia corresponding to musical recordings or the like. The panel 50 terminates in a horizontal lip portion 52 that terminates in flush overlying arrangements to the forward marginal end of the base 6. The lip 52 is provided with an elongated aperture 53 that engages over the latch head 20 and whereby the latch head projects above the lip for operative engagement by the finger of an operator. The housing 46 at its rear end is hingedly supported as at 54 whereby to permit the housing to be bodily elevated for exposing the mechanism supported upon the base plate. The housing 46 at its rear portion is also provided with a plurality of cabinets 55, 56 and 57. The cabinet is provided with a closure door 58 having a site opening 59 whereby to expose napkins or the like. The cabinet 56 is provided with a closure door. 60, preferably transparent and with the cabinet 56 supporting such elements as condiments or the like. The cabinet 57 is provided with a louvered front wall 61 and with the cabinet being provided with a conventional sound speaker, not shown. The speaker mechanism is of a conventional construction and prefer- Welded to the block 10 and extendably to be actuated by any well known coin device that is time controlled and the panel 50 may carry a volume control button 62 that is electrically connected with the speaker mechanism whereby to vary the volume of the sound. It is contemplated of course that the speaker shall be connected through suitable electrical conductors to a remote reproducing machine usually disposed within the main building of the drive-in restaurant and preferably embodies a 2-way communication system employing a speaker. Other signal means, such as a button 64 and visual signal 63 are preferably disposed upon the panel 50, whereby the button 64 may be electrically connected to suitable signal mechanism within the restaurant and whereby attention may be directed to the fact that service is desired at a particular vehicle. Various electrical circuits may be employed in connection with the support, all of which are conventional and well known and form no essential part of the structure herein recited. Suitable illuminating lamps will obviously be employed upon the base 6 whereby to illuminate the site openings 51 and 63. It is contemplated that all of the parts shall be constructed of a metal that is resistant to corrosion or rusting.

It becomes necessary that the housing 48 be locked against unauthorized elevation above the base 6, such being necessary in view of the fact that the speaker mechanism is coin controlled and that obviously there will be a coin receptacle below the cabinet 57. To provide for the locking of the parts together, there has been provided a rod 65 having one end threaded at 66 for threaded engagement within a lug 67 carried by the housing 46. The rod at its opposite end is provided with a key actuated lock mechanism 68. The lock mechanism 68 is connected to the rod 65 by a pin 70 and the rod may be released and wholly removed through the medium of a key device 71. The rod 65 extends transversely of the support and passes through apertures 72 formed in the angle arms 9. Thus with the rod in position, the housing 46 is securely held against unauthorized elevation.

in the use of the device, when a vehicle drives within the driving lane, the patron stops at a point adjacent a standard 44. He then reaches out and swings the support 5 toward the vehicle and if necessary elevates the support so as to permit it to partially engage over the sill of the window opening.

Since a menu is usually supplied with articles of this type, the operator proceeds to determine the particular service desired and then presses upon the button 64, causing a signal to be displayed within the restaurant. During the time necessary for consuming the food, the operator may insert a coin within the coin slot for the speaker and causing a circuit connection whereby the speaker will be placed in connection with a reproducing machine within the restaurant for a predetermined period of time. As before pointed out, napkins and condiments are readily available from the cabinets 55 and 56. Through the medium of the arms 26 and 27 and the rigid arm 42, the support may be easily adjusted to a most convenient position within the window opening. The use of the spring biased arms 26 and'27 permits of a quick and easy adjustment of the support in a vertical plane in order to accommodate it within window openings of varying heights. Now, when the operator has consumed the food, he signals again to the restaurant by pressing the button 64 at which time the entire device is shifted rearwardly away from the vehicle through the medium of the arms 26, 27 and 42, thus permitting the vehicle to be driven away without interference with the device. The bed 47 is of a size calculated to support a conventional tray whereupon is disposed the food products to be consumed.

It will be apparent from the foregoing, that a very novel tray support has been provided. The device provides an adequate area for supporting a tray and has the added features of providing and protecting the napkins and the condiments from the weather and provides an available support that readily accommodates itself as to height and extensive movement from its fixed support 44. The extension movement obviously is necessary in view of the fact that the distance of the vehicle from the support quite frequently varies. The device has the added desirable feature of a sound speaker that is coin operated and whereby the driver of the vehicle may, if he so desires to be entertained while he is eating. The parts are few and simple, are ornamental in appearance, are strong,

durable, economical to manufacture and most convenient as a service device for drive-in types of restaurants.

It is to be understood that while a preferred form of the device has been illustrated, changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the su'bjoined claims.
