Specifications Referring to Fig. 1, the numeral indicates the container housing the entire spring-wound mechanism 21,'the latter consisting primary of three supporting frames 22, 23 and 24 held together by means of supporting and spacing frame studs 20a, 20b, 20c and 20d. The entire spring mechanism 21 is secured to the container 20 by means of the fastening screws Me [and a-pair of flanges-20g both extending beyond the frame 24. A hinged cover 25 encloses the mechanism 21 within its container 20.

Referring more particularly to the supporting frame 24, it has a circular opening 26 fitted with a solid bearing 27 which is in perfect alignment with an opening in the supporting frame 23 which is fitted with a bearing 28. A spring winding shaft 29 is mounted in the bearings 26 and 27 with one end 29 secured to a winding handle or knob 30 and the other end fastened to the inner and 31a of the spring 31. The spring 31 is housed in a container 32 with its outer end 31b riveted to the latters rim. The operation upon the knob 30 winds the spring within its container 32 and places the latter under tension.

A spur gear 310 is securely held to the outer surface of the container32, its teeth being in mesh with the teeth of a stud gear 34 that is mounted upon a shaft 35 and secured to a larger spur gear 36. In turn the gear 36 is in mesh with a stud gear 37 mounted upon a shaft 38 that is secured to a larger spur gear 39 with the latter in mesh with a stud gear 40 that is mounted onto'a shaft 41 and secured to a larger spur gear 42. The teeth of the spur gear 42 mesh with the teeth of the stud gear 43 that is mounted to a shaft 44 and is secured to a larger gear 45, while the latter is being in mesh with the teeth of the stud gear 46 being held upon the shaft 47.

The end 48 of the shaft 47 has a fly governor 49 that in the main consists of a pair of governor shoes 50 being hinged to the shaft 47 at 50a and 50b. The operation of the governor will be described later.

The governor shoes 50 are being enclosed within a tapered shell 51 which may be moved laterally by means of the threaded shaft 52 which rotates within the threaded portion 54 in the frame 24 and ope-rates by the exterior knob 53. p

The shaft 38 extends beyond the rear portion of the container 20 and serves as a support for a bushing member 55 which is fitted with a knob-screw 56 to make tight the rear end of the spit (S) which is fitted into a square opening or hole 57in the bushing member 55 and is held securely by means of the knob-screw 56. The bushing member 55 serves in this case as a coupling to holdthe spit (S), to the spring-wound mechanism.

Referring to Figs. 6, 7 and 8, the rotisserie racks in the main consist of an upright hollow member support 58 hens 7 tion of the sliding member 59, is likewise equipped with a similar spit ear 61. At the lower end 62 thesupportSS is provided with a bushing fitted with a set screw 63-which serves to hold in place the sliding member '59 within the hollow of the tubular member 58.

A sliding ring or bushing 64 is fitted with a' plurality of mountings (in this case four or three) 65 servingas supports or bearings for the legs 66 of the rotisserie racks.- The legs in question are secured and hinge to the mount; ings 65 by means of the mounting pins or studs 67.

Referring more particularly to Fig. 9, it shows in per spective the 'ca'rrying'c'ase' which in the main includes the housing (H) the cover for the housing (C) and the carrying handle (HC'). In Figs. 4 and 5 it is shown 'how the rotisserie is used for roasting meats over an open outdoor hearth fire. lt-is understood that the same rotisserie may be used 'in an indoor hearth.

In Fig. 4, the spring wound mechanism 721 ismop-med directly within the carrying case (H) the latter taking the place of one of the rotisserie racks (11). In Big. 5, two similar racks (R) are used with the spring-wo pd mechanism 21 being rigidly secured to one of the rotisserie racks (R) by means of a clamp and screw arrangement (X).

Referring to Figs. and 11, the spit (S) consists in the main of a square (or round) vspitmember 69 and 70. The member 70 has on one end thereof a sharp point 70a while at the other end 70b an elongated slot 7 1. The member 69 has one end 69a bifurcated with a pin 72 extending across the arms of the bifurcation and loosely engaging in the slot 71 of the member 70. In addition,

the end 7% of the member 70 has an extension 73 and the end 69a ofthe member '69 has ahole 74. When the spit members 69 and 70 are extended to -their"full length, the extension 73 is fitted into the opening 74 to permit both members to remain in a straight alignment. To fold the members into two halves, the extension 7 3 'is disengaged from the opening 74 until the members are free to hinge my means of the pin 72 in the slot 71.

Fig. 12, shows a perspective view of another modification as shown and illustrated in Figs. 1 to 11 inclusive. In this case the housing (H) serves as a complete rotisserie including the driving mechanism and spit support racks. Numerals 75 and 76 indicate a pair of hinged arms held upon the lower portion 77 of the housing (H). A secondary pair of arms 73 and 79 hinged at 78a and 79a to the arms 75 and 76-respectively are provided to'serve as a secondary upright rotisserie support. The arms 78 and 79 are provided with holes 80 into which is fitted the sharp end 70a of'the spit (S), when said arms 78 and 79 are swung upwardly to the positions as better shown by Fig. 12 of'the drawings, where the arms cross each other withselectedholes 80 in alignment. To change the height of the roast over the hearth fire, the spit '(S) is lowered by lowering the entire springwound mechanism within the housing (H) and also by relocating the sharp end 70a of the spit (S within another pair of holes 80 on the members 78 and 79 as shown in dotted lines in Fig. 12.

Fig. 13,, shows the mannerin which the spit.(S) may be mounted to the spring-wound mechanism separately and independently of its train of gears. In this case the spit (S) has a separate handle a and a gear 81 which is placed over the stud gear 34 and is in mesh with its teeth. The spit can be removed from the rotisserie proper by simply lifting it from a slot 82 cut into the wall of the housing (H).

Fig. 14 shows the application of the spring-wound mechanism'shown in'Figs. .l to 13 inclusivet o outdoor wheeled rotisseries. In this casetthe outdoor rotisserie is equipped with a frame (F) fitted witha set of wheels.(W and a handle (h) to wheel it about. ,The spit (S) is mounted over the charcoalhearth (c) and is operated by a spring-wound mechanism 20a located at the side 21a of the frame 211) of the wheeled rotisserie. The spit (S) can be removed from the wheeled rotisserie without interfering with the mechanism 20a by means of the handle 3111).

Referring to Figs. 15 and 116 the rotisserie is shown provided with a charcoal tray 8 3 and the rotisserie housing (H) secured thereto by means of the hinges 83a. A pair of brackets 84 is also provided to hold the rotisserie (H) in an upright position while the tray 83 is held upon a pair of folding leg supports 86 and 87 hinged to extensions 86:; and 87a under the tray 83. When the rotisserie shown in Fig. ;l5, is not in use'it may be folded into'a compact unit as shown inFig. 1'6,

Operation To operate the rotisserie shown in Figs. 1 to 11 inclusive, the various parts of the unit are removedfrom its portable carrying case (H) and are assembled over an open hearth outdoors. When the rotisserie racks are used (two in number), the racks are placed on either side of the open hearth and their individual height over the fire is adjusted by means of the screwknobs 63 and 65a. The spring-wound mechanism 21 is secured to one of the rotisserie racks (R) by rneansof the clamp (X); one end of the square-shaped spit (S) then is fitted into the square opening or hole ,of the bushing or coupling and by means of the knob screw 56 it is made tight, while the other end of the spit (the sharp end) is inserted into the spit ear (see Fig. 5). The poultry or meat to be roasted is subsequently speared onto the sharp spit end and is secured to the spit proper by means of the sliding adjustable prong carrying plates (P), the latter being fitted with a'plurality of sharp pins 2) which are forced into the poultry or the meat to be roasted to hold it securely upon the spit while it rotates to roast the meat evenly around all sides.

When the poultry is properly mountedthe spring-wound mechanism 21 is wound by means of the'handleor knob 30 and the speed of the rotation of-the spit is regulated. This task is accomplished by means of the governor knob 53 which is manipulated by hand. The governor has four designated speed positions; one position is for ofF with the spring-wound mechanism at standstill and the spit (S) not rotating; another position is for slow," another position for medium speed and a fourth position for high speed. There 'are many other speed positions availablein addition to these four'and by proper manipulation upon the regulating knob 53 they maybe had at will.

Whiletworack supports (R) maybe used, one may.be dispensed with and in its place may be used the carrying case (H) of the unit. Such an arrangement is shownin Fig. 4. In this latter case, the spring-wound mechanism 21 is fitted withinthecase itself and is adjusted as :to the proper height and position over the open fire of the hearth. When theroast needs be moved closertothe fire, the spit (S) may-be placed over the lower ears 61 ofthe racks (R) with the spring-wound mechanism 21 also appropriately moved lower. In this case the spring-wound mechanism is secured by the clamp (X) to the sliding member 62 of the rack (R) instead to the rackmember 58. To move the spring-wound-mechanism 2l within -the container (H) the latter-is provided witha sliding groove (g) which is machined in the side frameof the container (see Fig. 9).

The rotisserie may also be-provided with a musical clock (M) to measure and to report when-the time approaches to rewind the spring. Such-musical instrument may consist of a very simple music-box mechanism operated by means of-pins-secured to a-rotating drum operated by the rotation of'the gears in-the spring-wound mechanism 21. When-the rotation ofthegears in-the spring mechanism stops, the tune will be discontinued; an indication that it is time to rewind the mechanism.

In Fig. 12, which is a modification of the-mechanism shown in Figs. 1 to 11 inclusive,-the racks (R) are dispensed with and the entire unit is made compact'and portable. Inthis casethe housing (H) -is provided'with a. flanged bottom, its lower portion'77 carrying two hinged extension arms and'76 preferably made of flat stock. To these, at 73a and 79a are hinged two spit supporting arms 78and 79 which have a plurality of holes 80. To operate the rotisseries shown in 12, the extension arms 75 and 76 are hinged free from the bottom ofthe housing (H) until they lay fiat upon the'hearth, then the supporting arms 78 and 79 are hinged up until two of the'holes are in alignment. To adjust the 'heightof the spring-wound mechanism in the housing (H) the entire spring unit is moved until the sharp point 70a of the spit (S) is at the same height with the holes 80 in the arms 78 and 79, then the unit 21 is made tight by means of the screwknob 20e (see Fig. 1).

In the case of Fig. 12, the spit (S) is not secured to a coupling 55 as shown in Figs. 1 to 11 inclusive but is a separate unit consisting of the spit (S), a spit handle 30a and a spur gear (s) secured permanently to the spit. The housing (H) is provided with a slot 82 into which the spit with its gear is lowered until the gear (s) contacts the stud gear 34 of the spring unit 21. It can be seen that to remove the spit from the rotisserie shown in Fig. 12, only the spit (S) is lifted by means of the handle 30a and its gear (s), otherwise the entire unit of the springwound mechanism 21 remains within the housing (H), (see Fig. 13).

In Fig. 14, it is shown the application of the springwound mechanism shown in Figs. 1 to 13 inclusive to wheeled garden rotisseries. In the latter the hearth is portable and may consist of a carriage body (F) with a handle (h) and wheels (N) to be wheeled about. Upon the hearth (F) there are supports 21b to support the spit (S) which is similar in construction to the one shown in Fig. 13. The spring-wound mechanism 21a may be secured permanently to the supports 21b and may be provided with a winding handle or knob 30b. The springwound mechanism 21a is similar in construction to the one shown in Figs. 1 and 13. To remove the roast from the wheeled rotisserie, the entire spit unit including the spit (S), its gear (s) and the roast is raised off the rotisserie by means of the handle 30a.

When not in use, the rotisserie shown in Fig. 16 is in folded position. To unfold the device, the housing (H) containing the spring-wound mechanism 20 is hinged upwardly upon its hinges 83a until it stands upright held securely by the brackets 84. The spit (S) is supported upon the supporting arms 78 and 79 while the charcoal tray 83 is held above ground by the legs 86 and 87.
