This invention relates to incubators and has special relation to egg tray racks and has special reference to means for supporting and simultaneously tilting a series of egg tray racks. v

One important object of the invention is to provide an improved and novel arrangement of egg tray racks whereby eggs held in trays supported in said racks may be quickly and l0 easily turned through at least a quarter circle.

A second important object of the invention is to provide a novel arrangement of operating mechanism for such racks whereby the may be shifted between positions in whic they are tilted 45 degrees in one direction to positions in which they are tilted 45 degrees in the opposite directions.

A third important object of the invention is the provision of means whereby such racks nay be simultaneously shifted'.

A fourth important object of the invention is to so arrange the racks and tilting mechanism that` the racks may be held in horizontal position for the insertion and removal of the egg trays.

A fifth important object of the invention is to provide a simple str'ucture for this purpose which will constitutea unit capable of insertion in or removal from an incubating chamber.

A sixth important object of the invention is to so arrange the tilting mechanism that it may be operated from the exterior of the incubating chamber.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter more fully described, illustrated in the accompanying drawings and claimed.

,In the drawings Figure 1 is a front view of the device showing the racks in horizontal position;

Figure 2 is a front view showing the racks tilted in one direction;

Figure 3 is a rear view with the racks horizontal;

Figure 4 is a rear view with the racks tilted oppositely to Figure 2;'

Figure 5 is a view from the right hand side of Flgure 4;

Figure 6 is a horizontal sectional view of the device;`

Figure 7 is a detail perspective view of 55 certain parts of t-he operating mechanism;

, Figure 8 is a detail perspective view of a corner of one of the racks;

Figure 9 is a detail elevation of such a corner from the rear of Figure8;

In the construction of the invention, there is provided a rectangular supporting frame having angle iron uprights 10 at each corner, these uprights being provided with feet 11 and connected in pairs at the front and rear of the device by cross members 12. Diagonal braces 13 connect the members 12 and other diagonal braces 14 connect the front and back uprlghts 10. Also, the front and rear frames are connected by cross members 15 at the top 70 and bot-tom.

The front and rear frames each have the legs 10 connected by vertically spaced bars 16 A and these bars may be braced at their middle points by auxiliary legs 17. The frame thus arranged is intended to accommodate a plurality of stacks of tray racks. Each of these tray racks consists of a pair of angle bars having a horizontal leg 18 and an upstanding leg 19. The ends of the horizontal legs are turned down as at 20 and the turned down ends of one angle bar of the rack are connected to the turned down ends of the other by side bars 21, the angle bars constituting the front and rear ends of the rack and the up- 35" turned flanges 19 forming stops to prevent the tra s (not shown) from sliding olf upon the rac being tilted. Each rack has its side bars 21 provided with outwardly offset portions 22 secured to the respective bars 16 by 9 pivots 23 so that each rack is freely tiltable on said pivots.

For simultaneously tilting all the racks and for holding them inparallel position there is provided, at the rear of the device, an inverted. U-shaped yoke having vertical legs 24 ivoted to the frames 'of the respective stac by pivots 25, the legs 24 beingconnected at their upper ends by a cross member 26.

Mounted on the rear members 16 is a vertical 10 `journalled and at its end this shaft is provided with a Worm wheel 34 wherewith meshes a worm 35 fixed on a shaft 36 journalled in the bearing 33. The shaft 36 extends parallel to one side of the frame and is supported at its opposite end by a bearing 37. On its forward end the shaft 36 carries a crank 38 and this crank may obviously be located outside the incubating chamber simply by giving the shaft 36 the necessary length.

. It is to be noted that the corners of the racks are braced by the braces 39.

In operation the crank is rotated until the racks are brought to horizontal position and in this position they are loaded with the trays full of eggs. The crank is now turned until the racks assume a position of substantially 45 degrees from the horizontal and thereafter, until incubation is complete, the crank is manipulated to alternately shift the racks between their initial inclined Vor tilted positions to positions -at right angles thereto. Finally, upon completion of incubation, the racks are brought to horizontal position and the trays removed.

There has thus been provided a simple and eicient device of the kind described and for the purpose specified.

It is obvious that changes may be made in theform and construction of the invention" without departing from the principles thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described but it is desired to include all such as come within the scope claimed.

`Having thus described the invention what is claimed is -1. In an egg tray supporting device, a frame, a plurality of series of tray racks spaced one above the other and having their sides pivoted to said frame, a vertical tie bar for each of said series of racks to which the racks of the respective series are all pivoted in spaced relation to the pivoted axes on I frame, a plurality of series of tray racks which they tilt, a cross bar connecting said tie bars for simultaneous vertical movement, and means to raise and lower said cross bar.

for vertical sliding movement, a connecting rod connecting the rack bar and cross bar, a gear meshing with the rack bar, a shaft supporting said gear, and means to rotate said shaft in either direction.

3. In an egg tray supporting device, a frame, a plurality of series of tray racks spaced one above the other and having their sides pivoted to said frame, a vertical tie bar for each of said series of racks to which the racks of the respective series are all pivoted in spaced relation to the pivoted axes on which they tilt, a cross bar connecting said tie bars for simultaneous vertical movement, a rack bar mounted on the rear of said frames for vertical sliding movement, a connecting rod connecting the rack bar and cross bar, a gear meshing with the rack bar, a shaft supporting said gear, a second shaft extending from rear to front of said frame, gearing connecting the first shaft and the rear end of the second shaft, and any operating crank on the front end of the second shaft.

In testimony whereofI aiiix my signature. CLAUDE M. LOWER.

2. In an egg tray supporting device, a

spaced one above the other and having their sides pivoted to said frame, a vertical tie bar for each of said series of racks to which the` racks of the respective series are all pivoted 1n spaced relation to the pivoted axes on which they tilt, a cross bar connecting said tie bars for simultaneous vertical movement, a rack bar mounted on therear of said frames
