text: as illustrated in fig1 the automatic kebab turner according to the invention comprises a support 1 for kebab skewers 2 and a mechanism for driving the kebab skewers . the support 1 has a front panel 1a provided with a plurality of slots 3 on its upper edge , and a rear panel 1b , also provided with a plurality of slots 4 on its upper edge . the slots 3 and 4 are open toward the top and are associated with one another in pairs with a view to supporting the two end parts of the kebab skewers 2 . to simplify the drawings , just one kebab skewer is represented in fig1 . the front panel 1a and rear panel 1b are substantially parallel and vertical and are joined together by two lateral panels 5 to form a rectangular frame , the bottom 6 of which may be open to be placed over a hearth or closed by a plate or metal grating on which a heat source is placed for cooking the kebabs . behind the front panel 1a there is a vertical partition 1c of the same length as the front panel 1a and parallel thereto with a view to forming with the front panel 1a a front compartment 1d in which a worm 7 is mounted , the ends of which worm are supported by the two lateral panels 5 of the support 1 . one end of the worm 7 is rotationally coupled by means of a driving square to the shaft of an electric motor 8 which is mounted on one of the lateral panels 5 of the support . the electric motor 8 may be driven by batteries or connected to a source of electrical energy by means of an electric lead which has not been represented . the motor 8 drives the worm 7 in rotation itself . each kebab skewer 2 is equipped at one end with a handle 9 which has a connecting part 10 made of a metallic material in the form of a piece of cylindrical overall shape provided with a cog wheel 10a intended to be meshed with the worm 7 . fig2 shows in more detail the structure of the handle 9 as well as the mechanism for rotationally driving the kebab skewer 2 by means of its handle 9 . the handle 9 comprises a part 9a for holding which may be made of wood or plastic which is a poor conductor of heat , and a connecting part 10 consisting of a metallic cylindrical piece . the cylindrical metallic piece 10 has one end 10b securely fastened to the part 9a for holding and followed by a peripheral circular groove 10c intended for positioning and keeping the handle 9 in a slot 3 of the front panel la of the support 1 . the cylindrical piece 10 has a central axial opening 10d to accommodate one end of a kebab skewer 2 . the kebab skewer 2 may be fixed permanently to the metallic piece 10 or advantageously fixed removably to this metallic piece 10 , it then being possible for fixing to be by means of a clip 11 housed in a peripheral groove 10e and locking the end part of the kebab skewer 2 in the central axial opening 10d of the cylindrical connecting piece 10 . in this way , the removable handles 9 may be associated with different types of kebab skewer . the worm 7 in the front compartment 1d behind the front panel 1a meshes with the teeth of the cog wheel 10a of the connecting piece 10 of the handle 9 . the teeth of the cog wheel 10a are advantageously curved so as to increase the surface area for contact with the thread of the worm 7 and improve the mechanical transmission between the worm 7 and the cog wheel 10a . when the kebab turner is in operation , the electric motor 8 rotationally drives the worm 7 which in turn rotationally drives the cog wheel 10a of the handle 9 . the kebab skewer 2 associated with the handle 9 is therefore rotationally driven to allow the foodstuffs threaded onto this skewer to be cooked . the rotational speed of the kebab skewer 2 is controlled by the electric motor 8 . in general , a certain number of kebab skewers 2 are placed on the support 1 . it sometimes happens that the rotation of one of the kebab skewers 2 becomes locked up in an untimely fashion , something which may occur for example when the kebab turner is exposed to inclement weather which causes seizure of the metallic piece 10 for connecting the handle 9 and the worm 7 and / or the slot 3 of the front panel of the support . the same phenomenon may occur in the event of a great deal of friction between foodstuffs which have been poorly threaded onto skewers or poorly cut to size on two or more adjacent kebab skewers . in this case , the invention makes it possible to avoid the locking - up of the kebab turner and allows the other kebab skewers 2 to continue to turn despite the fact that one of them has locked up . fig3 a to 3d illustrate this mechanism for automatically disengaging the kebab skewer which has locked up from the driving worm with the operational states illustrated . fig3 a represents the normal state of operation of the kebab turner with the cog wheel 10a of the handle 9 meshed completely in the screw thread of the driving worm 7 . the slot 3 on the front panel 1a displays an elbowed profile , the opening of which points upward vertically and the elbowed part of which points substantially horizontally , the external profile of the elbow being rounded . the lower edge 3a of the elbowed part is slightly inclined toward the bottom of the slot 3 which exhibits a semicircular profile for accommodating the bottom of the annular groove 10c of the connecting piece 10 of the handle . the screw thread , together with the direction of rotation of the worm 7 are selected so that the cog wheel 10a is driven in rotation in the direction indicated by the arrow 12 , which direction of rotation tends to press the bottom of the annular groove 10c of the handle into the bottom of the slot 3 on the front panel 1a as indicated by the arrow f . the elbowed part of the slot 3 has an upper edge 3b which prevents the upward movement of the handle , in order hence to ensure a perfect meshing of the cog wheel 10a with the worm 7 . fig3 b and 3c diagrammatically illustrate the disengagement of the cog wheel 10a , the rotation of which has locked up , from the worm 7 . the rotation of the worm 7 imposes , by means of its screw thread , a movement of the handle which is locked up toward the opening of the slot 3 in the front panel 1a in the arrowed direction , moving away from the bottom of the slot 3 ( fig3 b ), the slight slope of the lower edge 3a of the elbowed part of the slot 3 favoring the movement of the cog wheel 10a away from the worm 7 . likewise , the rounded outer profile of the elbow in the slot 3 allows the locked - up cog wheel 10a to be disengaged from the worm 7 gently ( fig3 c ). thus , the locking - up of the rotation of one kebab skewer automatically leads to this skewer being disengaged from the drive mechanism which continues to operate in order to drive the other kebab skewers in rotation . it may happen that partial disengagement of the initially locked - up kebab skewer is enough to unjam it ( fig3 b ). the invention allows such semi - disengaged operation of the kebab skewer in question without complete disengagement ( fig3 c ) being necessary . fig3 d shows the mechanism for automatically engaging the cog wheel 10a of the handle of a kebab skewer laid down in the slot 3 in the front panel 1a , or just after disengagement of this skewer which was locked up . the direction of rotation and screw thread of the worm 7 rotationally drives the cog wheel 10a which is thereby pushed towards the bottom of the slot 3 as indicated by the arrow . the return of the cog wheel 10a towards the bottom of the slot 3 is favored by the slight inclination of the lower edge 3a of the slot 3 . engagement thus takes place automatically . the automatic engagement and disengagement mechanism which has just been described may be further improved by a specific cutting - out of the slots 4 in the rear panel 1b of the support 1 ( fig1 ). the profile of each slot 4 may be identical to the profile of the slots 3 of the front panel 1a of the support so that the kebab skewer 2 involved in engagement and disengagement is not shifted off axis with respect to the normal operating position . another possibility consists in providing an elbowed profile for the slots 4 in the rear panel 1b with a lower edge 4a of the elbowed part substantially parallel to the upper edge of the rear panel 1b and with the outer profile of the elbow at right angles . such a profile of the slot 4 favors the horizontal movement of the free end of the kebab skewer 2 during the engagement and disengagement mechanism sic ! and prevents this free end of the kebab skewer from coming out of the slot 4 during disengagement of the kebab skewer . the profile of the slot 4 combined with the profile of the slot 3 makes it possible to accommodate floating kebab skewers . what happens is that in the event of friction due to poor cutting to size of the foodstuffs threaded onto adjacent kebab skewers , the specific profiles of the slots 3 and 4 allow a right - to - left or left - to - right lateral movement of the kebab skewers . this lateral movement ensures correct positioning of the kebab skewers as a function of the size of the foodstuffs threaded on them , to allow correct rotation of the kebab skewers . by virtue of the invention , automatic kebab turners may be produced which are particularly reliable in operation , accidental locking - up of one of the kebab skewers automatically leading to the disengagement of the latter , without the driving of the other said kebabs being disrupted . fig4 to 7 show a few applications of the invention by way of examples . fig4 represents a conventional barbecue made with the aid of the invention , the support 1 being mounted on legs 13 . the bottom 6 of the support 1 serving as a support for the hearth sic !. fig5 shows a large dimension work surface for professional use , which can be set into a kitchen unit . fig6 shows a system in the form of a self - contained kit which can be fitted to other items of apparatus . the front panel 1a and rear panel 1b are joined together by two telescopic members 14 making it possible to adjust the separation between the two panels . the front panel 1a and rear panel 1b of the support may exhibit slideways 15 allowing the ends of the members 14 to slide with a view to adjusting the separation between the two members . fig7 diagrammatically represents a vertically mounted electric kebab turner . in this specific case , it is preferable for the slots 3 and 4 to exhibit the same profile , which emerges in the edge of the panels 1a and 1b of the kebab turner in a way which is slightly inclined upward . such a profile of the slots 3 and 4 makes it possible to avoid the kebab skewers 2 being able to leave the slots easily . a lid 16 in the form of a glazed door may close off the exposed face of the apparatus . the hearth here consists of an electric element 17 located in a vertical plane close to the bottom 6 of the support 1 . as emerges from the foregoing description , the invention makes it possible to produce an automatic kebab turner which exhibits numerous advantages . it is simple , reliable and inexpensive . it is not prone to seizure due to inclement weather and has no possible locking - up of the other kebabs in the event of one of them locking up , by virtue of the mechanism for automatic disengagement and automatic engagement of the handles associated with the kebab skewers . the kebabs float in the horizontal direction ( owing to the width of the elbowed parts of the slots 3 and 4 of the front and rear panels of the support allowing these , in the event that the foodstuffs threaded onto the skewers have been poorly cut to size and in the event of friction between the foodstuffs , to position themselves correctly so that they can continue to turn sic !. it requires no fixing of the kebab skewers in the support . the handle may be removable to accommodate any type of kebab skewer whatsoever available for sale commercially . it makes it possible to use a highly autonomous micromotor which runs on electric batteries , which therefore gives the kebab turner a high degree of mobility , etc .
