JOHN MAXHEIMER, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN BIRD-CAGES.

Specification forming part of Letters Patent No. 15?,998, dated December 22, 1874; application filed November 14, 1874.

To all whom it may concern Be it known that I, JOHN MAXHEIMER, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Bird-Cage, of which the following is a specification:

Figure 1 is a side view, partly in section, of my improved bird-cage. Fig. 2 is a detail transverse section of the same, and Fig. 3 a top view of the bottom of the cage.

Similar letters of reference indicate corresponding parts in all the figures.

The object of this invention is to produce a convenient mode of attaching the body of a cage to the bottom of the same, in such a manner that the two parts cannot be spontaneously disconnected; and. my invention consists in forming on the body of the cage a series of downwardly-projecting loops, and on the bottom of the cage, in a groove or depression thereof, an equal number of horizontal pins or hooks, so that the loops aforementioned may be brought to embrace such pins, and to thereby connect the bottom to the I body of the cage.

In combination with this mode of connection I use the sliding door of the cage for looking the parts together, said door having a loop or eye, which, when the door is closed, embraces an upwardly-projecting pin of the cage bottom, as hereinafter more fully described.

In the accompanying drawing, the letter A represents the bottom of the cage, made of sheet metal or other suitable material, of circular or other convenient form. B is the cage body, made of wire or other material, in suitable form. C is the door of the cage, arranged, by preference, to slide up and down in suitable guides.v The body B has three, more or less, downwardly-proj ectin g loops or eyes, a a, formed on it, of Wire or other material. The bottom A has a trough, depression, or groove, b, formed in it, so that when the body B is placed upon it the several loops or eyes a will enter such groove or trough. This trough or depression is to prevent the lower part of the body B from being raised by the loops a too high above the bottom. In this depression I; of the bottom are secured as many horizontal pins or hooks d d as there are loops a on the body. Every such pin or hook is secured at one end to the bottom A, while its other end is free, as shown in Fig. 1. When the cage B is to be secured to the bottom A the cage is turned on the bottom until the several loops on embrace their corresponding pins d. The requisite connection is then established.

It is evident that a return motion of the cage may readily disengage it from'the bottom A. To prevent this from taking place spontaneously I have arranged an upwardly-projecting pin, e, on the bottom A, and a projecting loop, f, on the door 0. Said door is let down after the body B has been properly applied to the bottom A, and causes thereupon the pin 0 to enter the loop f. The body B is thereby prevented from further turning on the bottom A, and consequently the conmotion of parts becomes absolute.

Now, in case it is desired to separate the parts A B it is only necessary to raise the door 0, and liberate the cage-body thereby from the pin 0. The cage-body can then be turned to disengage its loops from the pins (1.

Instead of having the projecting loop f on the door 0 and the projecting pin 0 on the body A, I may have a downwardly-projectin g pin on the door, entering a loop or perforation of the bottom; and also, instead of having the loops at on the body B and the pins d on the bottom A, the pins may be applied to the body and the loops to the bottom.

' I claim as my invention The combination of the body B of a birdcagewith the bottom A, loops a, pins or hooks d, and .the sliding door 0, which serves as a lock for the connections, substantially as specified. y

The above description of my invention signed by me this 13th day of November, 1874.
