EGG-TURNING nnvicn.

Application filedjian uary 6, 1926. Serial No. 79,537.

My invention relates to means for hatchfiling poultry, and has for its object to pro vide a new, rapml and efficient device for turning theeggs in an incubator. I

5 A further object is to'proVide a case wherein more eggs may be placed and hatched within a predetermined sized incubato-rthan has heretofore been done on a self turning device, and in which the chicks may be hatched and kept until they are ready to be placed in the brooder.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this applica-' tion and as pointed out in the appended claims.

In the drawings in which I have shown the most preferred manner of carrying out my invention, Figure l is a plan View of the base or bottom of the apparatus. Figure2 is-a longitudinal section on line 2-2 of Figure 1. Figure 3 is a plan view of the turning rack. Figure 4 is a longitudinal section on line t-4 of Figure 3, and Figure 5 is a side elevation of an apparatus assembled within an incubator, with dotted lines to show the length of movement of the turning rack.

It is the required and common practice to turn eggs in the incubator two or three times each day during incubation, and to turn each egg by hand requires the removal of the trays, the turning of the eggs by hand and the replacement of the trays holding the hand turned eggs to the incubator, and with my apparatus I am enabled to turn 40 every egg, without removing the trays from the incubator, and in very much less time than has heretofore been done.

My apparatus consists of a wooden frame "A, preferable rectangular in form and of size to fit the incubator within which any number of them may be used. The bottom for said frame is of closed meshed wire screen B. Between opposite sides of said frame A, I secure spaced apart strips of friction material C shaped as'a segment of a cylinder, and with the arc sides of earh bearing against the screen bottom B. A turning rack D is superimposed on each of said frames and the sides of the incubator or other adjacent racks keep the racks in vertical alinement with their coaeting frames A. I The said racks are given the same shape and width as the frames A but are one section shorter, and eaeh'raeltcoir sists of a metal frame 1 with the lower edges inwart ly flanged, as at I provide parallel wire cross pieces 3 which are spaced apart the same distance as the segment cylinders C and normally said cross wires are positioned vertically over said segment member C and are spaced above said segments. The

said cross wlres 3 are made by bending a single wire at the required length to reach from side to side of said metal frame. 1. with short lengths bentvat right angles thereto to space the longer lengths the required distances apart and back and forth across the frame. The wire frame thus constructed is soldered to and rests upon the flange 2 of the metal frame 1 which construction gives a rigid, light weight, and easily cleaned rack D. There are one less cross wires 3 than the segments cylinders C to allow the rackD to slide lengthwise.

The cross wires 3 are spaced far enough toallow an egg to be placed on the wire screen with its shell touching the adjacent friction strips G and two of the cross wires 3. The eggs may be placed on their ends or sides and closely positioned as to each other. To turn the eggs the rack D is moved longitudinally endwise, which movement will roll the eggs'over one of said frictional strips into the trough formed by the spaced apart wires and the adjacent friction strip, and at the next turning, which is effected by sliding the rack in the opposite direction the eggs will assume a different position but will be returned to the trough .in which they first rested. The chicks may be hatched on the frames with the screens'providing a floor on which they may stand. or sit.

Having thus described my invention I desire to secure by Letters Patent and claim 1. In an egg tray for use in incubators the combination of a base, having a screen bottom thereto; transversely disposed semicylindrical strips, secured thereon: a turning rack superimposed over said base, having transversely disposed cross wires thereon, adapted to carry eggs between themand to force the eggs over the said semicylindrical strips on said base when saidturning rack is moved longitudinally on said base, to turn the eggs over.

2. In an egg turning tray the combination of, a base; having side walls thereon;

ios

a wire screen secured in the bottom of said base: transversely disposed semicylindrical strips on said wire and secured between the walls of said base; a turning rack resting on the edges of said side walls and adapted to be moved longitudinally along said walls; of said base; cross wires secured transverse- 1y across said turning rack adapted to hold rows of eggs between wires and to turn said eggs when said rack is moved longitudinally on said base.

3. In an egg tray for use in incubators the combination of a rectangular frame; wire screen secured on the. bottom of said frame; semicylindrieal friction strips -semicylindrical side of said strips upward;

a similar frame superimposed on said first mentioned frame butshortcr than said first mention frame; cross wires secured in said second mentioned frame to hold eggs therebetween in asemiuprightposition; and to turn said eggs when said frame is moved longitudinally upon said first mentioned frame.

In testimony whereof I have aflixed my signature.

GEORGE M; vTURPIN.
