the novel mechanism for simple and easy operation.

A final, but nevertheless important object of my invention is to reduce the mechanism to extremely few parts, in order that the same may involve a small amount of labor and a minimum cost of materials.

\Vith the above objects in view and any others that maysuggest themselves from the specification and claims to follow, a better understanding of the invention maybe gained by reference to the accompanying drawing, in which s Figure 1 is a side elevation of a typical crib, illustrating my improvement;

Fig. 2 is an enlarged elevation of the parts immediately involved in the drop-side mechanism; and

' Fig. 3 is a section on the line 33 of l igure 2.

It is a familial fact that on cribs of the drop-side type, operating mechanisms, of a more or less involved nature have been employed, these mechanisms often comprehend- I ing delicate parts which get out oforder in a short time. Also, the costs of producing the structures have been high, and the medium of operations has inmany-cases required undue attention or effort. In cases of this nature,'the mechanism is more of an impediment than a benefit,especially when it is considered that the crib is an article of light furniture and the operator is usually a person without mechanical skill. It has therefore been myintention to eliminate the above Another object of my invention is to design .Byspecific reference to the drawing, 5 denotes the endposts, and ('3 the angle-iron bed' frameof a typical chilts crib. The end posts) are fitted with vertical guide rods 7 along' 'wh1cli operates,thedropside 8, the

latter actualy consisting ofthe upperand' lower ralls Sand mtermediate rods or other spacing'material 9. Y Full lines show the nor malgposition of the'i'lrop-side, and finely dotted lines in Figure 1 denote the loweredfposition thereof. 1 i

In order that thedrop-side may be suitably supported, I first attach by rivets 10' or other suitable means, the bases 11 of a'pair of angle brackets 11a upon the frontal section of the frame bar 6. Between .the brackets 11a I place a long bar 12, which has terminal reductious 12a whlch pass through slots'lll) cut in the respective wingslla. Tlie reductions 120$ are of arcuate crosssection, and the slots 11?) are of a similar curvature, clearly shown in Figure 3, so that the bar 12 is capa ble of being rocked or rolled byreason of its curved bearing, In proximity to each bracket 11a, aplate 13 is welded or otherwise a secured frontally upouthebar 12, this plate extending downwardly with a deflected por- :tion 130, whose direction is inwardly of the The vertical portion ofthe plate 13 is crib. cut with a vertically elongated slot 137), in which rests a pin let projected inwardly of the crib from a hanger-lawhose baselea' is horizontal. andjadapted to besecured to the under side. of the lowerdrop-side rail 8 by screws 16 or other means.

, Sincethe drop-sideis ofa free nature, except for its guidance along the lateral rods 7, it will be clear that it rests in the proper normal position by the support of the; pin 14 at the bottom of the slot 13]) in the plate 13, which itself has support in the brackets'lla.

However, if itisdesired that the drop-side be lowered all that is necessary istliat the dc; flected portionl3a of either plate l3 begiveni a light'lcick in a direction inward of tee crib; This will cause the plate'to swing in the direction of the arrow whereby to become disengaged from the pinl4, in which event the drop-sidelwill lose its supportand descend to lowered"position, as indicated by the'iinely dotted lines. Theshock of-this descent is erate at their best.

ating un1ts is such as to locate each of them usually'cushioned by suitable bufiers 17 at the'lower ends of the guide rods 7. v

" It will be seen that the relationof the bar reductions 12a and slots .116 performs the function of a hinge for the platesll3, but does not entail ,the complications of the typical hinge, The" peculiar construction I have devised enables the brackets 11a and the bar 12 to serve as supports and to embody be+ tween them a hinge relation withouttlie aid of a single extra part, so thatasimple and economical structure is the result. It is also significant that the slots ,llhmay be fashioned in a manner to perfectly control the strokes of the plates 13, so that these may op- The spacing of the opernear one end of thecrib, so that the attendant mayfind it justas handyxto operate the drop-side mechanism near one end of the crib as near the other. u Naturally it may be said thata single unitcould suiiice, since both units are identical however, where a crib is of considerable length, it'is advisable that a control be had near each=end.

It. is noted that the extensions 13a of the plates 13 are enlarged, this being toprovide sufficient surface for the application of the attendants toejwithout payingparticular attention at what point the toe is applied; The extensions are thus of ample width toenv able the attendant to actuate the mechanism Without especial attention.
