APPARATUS FOR PRESERVING EGGS.

SPECIFICATION forming part of Letters Patent No. 253,074, dated January 31, 1882,

Application tiled September 13, 1881.

To all whom it may concern:

Be it known that I, KELLOGG H. LooMts, of New York, in the county of New York, and in the Sta-te of New York, have invented certain new and useful Improvements in Apparatus for Preserving Eggs, and I do hereby declare that the following; is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specincation.

The nature of my invent-ion consists in the construction and arrangementof an apparatus for preserving eggs, and its object is to provide an economical and practical machine for carrying out this end.

It consists, tirst, in providing a means for effecting a thorough and equal instantaneous distribution ot'the preservingiluid orsubstance employed; secondly, in the construction of a tray or rack for securely supporting the articles under process of preservation, and retailiing them in the desired position against the contact of a displacing action caused by the sudden injection of the preserving-fluid into the reservoir; and, thirdly, in a cut-off cock or valve for opening and closing the communication between the reservoir and air or suction pumpin aquiek and positive manner. 'These ends Iaccomplish by the mechanism illustrated in the accompanying drawings, in which- A Figure l isa side elevation of my invention complete. Fig. 2 is a vertical sectional view ofthe same, showing its internal arrangement. Fig. 3 is a plan view thereof, and Fie. 4 is a detached plan view of a portion ot' my -improved tray or supporter.

TheletterA designates the supporting pieces orlegs employed for sustaining the body of my apparatus, to which they are suitably secured by bolts and nuts, or in any other convenient manner.

The letter B indicates the lower portion or section of the body or reservoir of my machine, and is constructed of cast metal. It is preferably of circular form, and is hollowed out, after the manner of a bowl. Atits upper edge I form an annular ledge or flange, B', somewhat below the extreme upper surface, which furnishes additional strength thereto, and pro- (No model.) o

jecting therefrom are lugs b, to which the supportinglegs above referred to are attached. Resting upon this lower section, B, and fitted thereto, is a similar section, (l, the ltottom edge whereof is provided with two annular flanges, C and c, the one fitting within the. section B, and the othercarryingarubberorothersuitahte packingring, l), located in the channel tin-med therein, the said packing-ring D being` interposed between the two sections and forming 6o an air-tightjoint. It will be observed that the upper head on the lower section, B, is slightly' roundingin its cross-section, the objectof which is that the same may the more readily take into and form acloserjoint u ith the packing-ring D.

At or near the center ot' the lower section, B, of my reservoir,is secured a stop-cock, F, which is used to open and close communication between the reservoir B O and the tank or vessel containingthe preserving-fluid. This 7o cock is provided with an upper extension, F', whichprojects upwardlyinto the tet-.tion B a short distance, where it is provided with a number of small apertures or pert'orations,j, the function of which latter will presently appear. Above these pert'orationsfthe said extension F is screw-tht Vxaded and carries two nuts, G and G', the upper of which is closed, forming a cap or covering for the extension, thus preventing an upward discharge ot' the 8o preserving-fluid.

Interposed between the nuts G and G and on the' extension F is a thindisk or circular plate, H, the diameter o1" which is regulated according to that ofthe lower section ot' theres- 85 ervoir, its periphery extending near the inner wall of such section, forming between the two surfaces a narrow annular way or space t'or the passage of the i'irescrving-tluid,the function of the said disk H beingto p1 event the preserving- 9o tluid from forcing its way directly upward into the reservoir, (which, on account of its high speed, would displace and damage the eggs,) and to spread the 'same in an even manner, allowing it to enter the egg-com partment only in a thin film or stream. Immediately above this disk H is suitably supported a tray or rack,I, for containing the eggs, which is formed ot' a convenientnumberot'concentricrings or bOODS, I, connected together by a series of smaller 10o rings, I, located in close succession between each concentric hoop. At the point of contact between each of the smaller rings and the latter with the concentric hoops I make a suitable connection by solder orotherwise. Atintervals around each ofthe smaller rings I attach thereto short pins or posts i, inclining inwardly or toward each other as they extend upward, fortning rests or supports for the eggs, between which the latter are held, and by which they are prevented from contact with the rings inclosing them,thus allowing substantiallytheir whole external surface to be acted upon bythe preserving-fluid during the process ot' sealing.

Ata suitablepoint,preferably near the center ot' the section C ofthe reservoir, I attach a twoway cock,J, the casing of which has two projections orextensions, J and K, tooneot' which, J', is secured ahose orsuction-pipe, L, the other, K, forming a communication between the cork proper and the external ait'. On one. end of this cock I attach rigidly a pulley-wheel, M, having a peripheral groove in which is tted and secured a spiral spring, N, the other extremity of which spring is connected by means of an interposed link, O, to a post or hook,P, on one side of the section C. To this pulley M is also secured a lever or actuating-arm, Q,by which the cock is put into communication with the reservoirand air-pump, and retained in that position until a vacuum has been formed in the reservoir, when the said lever is freed and the recoil of the spiral spring partially rotates the pulley M, which acts on the cock directly and instantly closes the communication thus established, and forms one between the air-pump attached to hose and the external air, the latter being the normal position of the cock. Near the said cock J is located on the section U a hand-cock, R, which isused for openv ing up a communication between the reservoir and the external air for the purpose of destroying` the vacuum which has been previously formed in the reservoir. At a suitable point on the said section C is also attached a vacuum-gage, which is employed to indicate the moment when the vacuum has been formed in the reservoir B C.

The operation of my machine will be readily understood from the following in connection with the foregoing: The section C being removed, tlle egg tray or rack is filled with eggs and the former then replaced. The cock J is then put in communication .with the reservoir and air-pump attached to one end of the hose L, and the pump put in motion and kept in operation until the air is exhausted from the reservoir. At that'nioment, as indicated by the vacuum-gage, the lever Q is released and the recoil of the'spring N then acts on the pulley M, giving ita partial rotation, which instantly closes the communication last referred to. The lower cock is then opened and a charge of silicate of soda (or other preserving or sealing duid) is admitted through the perforations in the pipe Ff, detlecting against the under side of the disk H, from which it radiates, and then passes upwardly into the reservoir until it is again deflected by the coucavity of the section C, from whence it descends in a spray-like form upon the eggs, completely coatingthem. This occupies but a moment of time. Then the handcock is opened and the vacuum destroyed,when the unconsumed sealing-fluid returns by its gravity to its proper receptacle. The section C is then removed and thepreserved or sealed eggs are taken out.

- It will be observed that while the process of preserving is in progress the air-pump and external air are in communication with each other, owing to the normal position ofthe twoway cock, thus relieving the exhaustion mechanism of the otherwise prolonged and continued strain.

In some instances I contemplate using a counterbalance-weight foroperating the pulley M instead ot' a spring, as above set forth.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

forated injecting-pipe, a deilecting-disk, and

an egg-receptacle, substantially as specified.

2. In an apparatus for preserving or sealing eggs, the combination of a detlecting-disk and an egg rack or tray, the latter consisting of a number of concentric rings or hoops, and a series of smaller rings located between the same, substantially as shown and described.

In testimony whereofI attix my signature, in presence of two witnesses, this 4th day ot' September, 1881.
