UNITED STATES PATENT OFFICE.
FREDERICK SCHMIDGALL AND HENRY KORNMANN, OF CINCINNATI, OHIO, ASSIGNORS TO THE CINCINNATI BUTCHERS SUPPLY COMPANY, OF CINCINNATI, OHIO, A COR- PORATION OF OHIO.
To all whom 'it may concern:
Be it known that we, FREDERICK SCHMID- GALL and HENRY KORNMANN, both citizens of the United States, and residents of Cincinnati, Hamilton count-y, State of Ohio, have invented a certain new and useful Auxiliary Refrigerator-Door; and we do declare the following to be a clear, full, and exact description of the invention, attention being called to the accompanying drawing, with the reference characters marked thereon, which forms also a part of this specification.
In slaughter and packing-houses and similar establishments, carcasses or parts (so called quarters or sides) of them, are moved from one part of an establishment to another and also in and out of refrigerators, cooling-rooms, cold-storage compartments, while suspended on trolleys which travel on overhead-tracks. These tracks are accordingly arranged and distributed throughout a plant, taking in also these cooling-rooms and cold-storage compartments so that carcasses may be run into them and out again while suspended. Openings are provided in the inclosures' of these compartments for access and to permit the suspended carcasses to pass through in either direction, which openings are extended upwardly at a certain point to admit also the overhead track, the extended part being of a size sufiicient to clear the tnolleys traveling thereon. Doors are fitted to these openings, there being also a smaller or auxiliary door for the extended part of this opening. his desirable, forobvious reasons, that both doors move together for opening, or closing, so that, when the larger door is opened to permit passing of a carcass, the smaller door opens also, to clear the trolleywhich carries the carcass, and when the larger door is closed, the smaller or auxiliary door closes likewise.
For this reason doors connected so as to move in the manner indicated, and mechanism to operate them accordingly, have been provided and our invention concerns improvements in such mechanism whereby this auxiliary door is automatically operated whenever the larger door is manipulated.
In the following specification and particularly pointed out in the claims at the end thereof, will be found a full description of our invention, together with its operation, parts and construction, which latter Specification of Letters Patent.

AUXILIARY REFRIGERATOR-DOOR.
Patented Dec. 19, 1911.
Serial No. 450,953.
is also illustrated in the accompanying drawing, in which Figure 1, shows in perspective view a portion of the outside of a wall which may form part of the inclosure of a refrigerator, cooling-room, or cold-storage compartment and is provided with an opening for access. Fig. 2, is an enlarged front-view of the auxiliary door showing it open. Fig. 3, shows the same closed. Figs. 1 and 5, are horizontal sections through the opening controlled by this door, this latter being shown in topview in both figures.
A may indicate part of one of the inclosing walls of a cold-storage, or cooling compartment. V
B is. an opening for access thereto, and through which the pieces of meat pass while suspended on a trolley C, which travels on an overhead track rail D. Opening B is extended as shown at to clear the rail D, and to permit also the trolleys which travel thereon to pass in and out-.
F is a door fitted to the large opening, conventional closing means G g, to be manipulated by hand, being provided to keep it shut. V
The door for the small opening E, consists of two wings or flaps H H, one on each side of track-rail D, at which they meet, the free edge of one or both being sufliciently cut out to clear the rail to permit these edges to come fully I together when the door is closing. Both wings are hingedly attached at opposite edges of opening E, and connected to each other in a manner that when one swings on its hinges, for opening or closing, the other is caused to follow. This connection of the wings to each other is suflici'ently above rail D to be out of the way of the trolleys which travel on this latter. It consists of an arm 8 rigidly attached to the inner side of one of the wings from which it projects, and of a link 9 which connects this arm to the other wing. The connection of the link at both of its ends is a jointed one, and where it connects to arm 8 it is also slidable, a slot 10 being provided in this arm.
The combined length of link andarmis such as to permit the wings to swing'apart sufliciently for the purpose, that is to permit a clear passage for the trolleys. See Figs. 1, 2 and 4. It is clear now, that if one of these wings is positively actuated by any means, the other wing shares in the effects of such actuation. e use door F as a means for this purpose and provide on the same, at or near its upper edge a projection 11, which is adapted to engage either one of two bars carried by the wings. When door F is being opened, this projection bears outwardly against a bar 12, and pulls the particular wing open. hen door F is being closed, the projection bears against a bar 13 and pushes the wing shut. By preference, both of these bars are combined in one structure, which may be a casting, and is provided with a flange 14 for its attachment to the particular wing.
Having described our invention, we claim as new:
1. In combination with the inclosure of a coolingroom having an access opening which is extended at a particular point, a door for this opening, an auxiliary door for its extension, which latter door consists of two, hingedly attached wings, means whereby these wings are connected to each other in a manner that when one is manipulated the other follows, and locking means to yieldingly hold one of the wings in open position.
2. In combination with the inclosure of a cooling-room having an access opening which is extended at a particular point, a door for this opening, an auxiliary door for its extension, which latter door consists of two, hingedly attached wings, means whereby these wings are connected to each other in a manner that when ("fine is manipulated the other follows, a device carried by the door first mentioned and adapted to actuate the wings accordingly, locking-means to hold one of the wings in open position and additional locking-means to lock one wing to the other.
3. In combination with the inclosure of a cooling-room having an access opening which is extended at a particular point, a door for this opening, an auxiliary door for its extension consisting of two wings which are operatively connected in a manner thatwhen one moves for opening or closing the other follows, two spaced bars carried by one of the wings, means provided on the door and adapted to interact with either one of these bars for the purpose of opening or closing the auxiliary door, and a spring-lock adapted to yieldingly occupy the space between the two bars mentioned when the wings are in open position to hold them so.
4. In combination with the inclosure of a cooling-room having an access opening which is extended at a particular point, a door for this opening, an auxiliary door for its extension consisting of two wingswhich are operatively connected in a manner that when one moves for opening or closing the other follows, a bar carried by one of the wings and adapted to extend over the other wing, to force the same to its seat at the end of the closing movement and means carried by the door first mentioned and adapted to actuate the wings. I
5. In combination with the inclosure of a cooling-room having an access opening which is extended at a particular point, a door for this opening, a hingedly attached auxiliary door for the extension of this opening, means whereby this auxiliary door is caused to open and close with the other door, and a closing-plate on this latter door adapted to lie across the auxiliary door when both doors move into their closing position.
6. In combination with the inclosure of a cooling-room having an access-opening which is extended at a particular point, a

door for this opening, an auxiliary door for its extension consisting of two wings, a slotted arm on one wing and a link pivoted to the other wing and slidingly engaged at its free end to the slotted arm and whereby the wings are operatively connected in a manner that when one moves for opening or closing, the other moves also, means carried by the door first mentioned and adapted to actuate the wings to open or close them and a pin on the slotted arm adapted to engage the free end of the link when the wings are open, thereby preventing the link from moving on the arm and holding the wings open.
