ATTORNEY April 18, 1950 s. B. GOLDSTEIN 2,504,


ATTORNEY engages and which will be hereinafter more fully described. The said corner posts G2 are further securely held together, at opposite ends of the crib, by transverse members 2| (Fig. 3), each of which consists of a top rail 22, a bottom rail 23 and vertical bars 24 which are fastened to the said top and bottom rails 22 and 23 respectively. Below the said bottom rail 23 there is secured a panel 25 which is attached at its'ends to the adjoining posts if, to the said bottom rail 23 and to the upper side of the aforesaid frame I5.

A bracket and capping member 26 is attached to the upper end of each corner post i2 and is formed with a partial bore 21. A second bracket member 28 having a bore 29 therethrough is also secured to the corner posts (Fig. and a third bracket member 38 is secured to each of the said corner posts. The bracket 39 has a bore 31. The upper end of the said central shaft section 20 has a contracted end portion 32 which rotatably engages in the said bore 29 of the bracket 28 and is formed with a squared recess 53 within which a coinciding squared projection 54 formed upon the lower end of an upper shaft section engages. The upper end of said upper shaft section 35 has a contracted circular projection which fits into the said bore 2'! upon the bracket 25.

The contracted lower end of the said central shaft section 20 is also formed with a squared recess 36 within which a corresponding squared projection 3'! upon a shaft 38 is adapted to engage. The lower end of the said shaft 35 is con --tracted to form a circular projection 85 thereon .of said corner posts l2, have formed upon their outer peripheral surfaces helical grooves 46 and engage through bores 4! formed upon the four projecting corners 42 of a mattress supporting frame 43. The said bores 4| have internally formed helical ribs which are complementary to the said helical grooves upon the said shafts 25. It is obvious that when the shafts are rotated, in the proper direction, the said rotation will urge the said mattress supporting frame upwardly from its lowermost position or downwardly from its uppermost position, when the said shaft is rotated in the opposite direction.

The aforesaid side drop panels, one upon each side of the crib, are each formed with a top rail 44 and a bottom rail 45 connected by vertical members 56. The outer ends of the top rails of the said side drop panels are formed with boss or knob 4'! having a bore 48 (Fig. 5); which is formed with a helical rib conforming to and engaging with a helical groove 49 upon the peripheral surface of the aforesaid upper shaft section The bottom rails 45 of the said side drop panels are similarly formed with a boss or knob 15f! having a bore 5| and a helical shaped rib conforming with and engaging a helical groove 52 upon the said shaft 38. Thus when the shafts comprising the three sectional portions 29,

and 38 are rotated in the proper direction, the said mattress supporting frame 43 will move upwardly while the said side drop panels will move downwardly as indicated by the dot-dash lines 53 and 5 respectively (Fig. 5) and by the full lines --in Fig. 2.

v By reversing the direction of rotation of the said -shafts 2d, 35 and 38 the said mattress supporting :frame 43 and the said side drop panelswill move downwardly and upwardly respectively to resume the position shown by the full lines of Figs. 1 and 5.

With the said mattress supporting frame and said side drop panels in their respectively normal, lowered and raised positions, the said activating shafts may 'be rotated by manually depressing or raising the said side drop panels.

Upon the said side drop panels there are provided weight blocks 55 of sufficient weight to counteract and balance the weight of the said the said motivating shaft mattress supporting frame and the friction of the rotating shafts.

The said sectional rotating shafts are coupled by means of a transverse shaft 56 mounted at each end of the crib and upon the ends of which there is attached a bevel gear 51 coacting and meshing with a similar gear 58 upon the lower end of each lower section 38 of the said rotating shaft. Upon each of the said shafts 55 there is provided a locking wheel 59 which is notched to receive the fin end 60 of an arm Bl which is in turn mounted upon a shaft 62 extending longitudinally across the lower portion of the crib and rotatably mounted in the said cross rails 54 at each end of crib and centrally thereof upon a cross channel 53. From the said shaft 52 there is attached an extending arm 64. terminating at its outer end in a pivotal connection 65 at which point there is attached a foot pedal arm 53 (Figs. 1, 2, 3 and 4). A spring 61 is provided to normally keep the locking member 60 in engagement with the said locking wheel 59. When the said fin end 66 is in engagement with the said locking wheel 59, the said mattress supporting frame 43 and its coordinating parts are held immovable. However. by pressing the foot pedal down the said locking wheel 59 is released and the parts may be operated. It will be noted upon the drawings, Figs. 1, 2 and 3 that the pedal 66 passes through a slot 61 in a depending plate 68 and that the slot 61 is formed with a broadened lower cut out to form ledges 69 under which the said pedal may be moved to hold same down.

In Figs. 9 and 10 there is shown a crank handle 10 secured upon a squared section II formed upon the upper end of the shaft 35. The outer end of the said crank handle 10 is provided with a pivotally attached L-shaped portion comprising a hand hold or knob 12 and a finger 13 which is adapted to engage in a slot 14 formed upon the cap member 26. With the knob 12 in the up right position shown in Fig. 9, the handle may be used to raise or lower the said mattress supporting frame and the coacting side drop panels. By turning the said knob 12 about its pivotal connection the finger 13 may be brought into engagement with the slot '74 and lock the parts against movement. The aforesaid shafts 55 (one at each end of the crib) may be connected by means of a bevel gear 16 upon one end of a shaft H, having end bearings on the cross rails I4 and bearing 18 upon the channel member 63 and bevel gears similar to bevel gears 15 and 15 at the opposite end of the said crib.

In Fig. 4 a portion of a mattress 19 is shown resting upon a conventional spring mounted upon the said mattress supporting frame 43.

In the drawings Fig. 5, the helical grooves 45 in the central section 2!! of the three sectioned motivating shaft are cut in such manner that when is given clock-wise rotation, the said grooves 40, when considered as imparting a downward movement to its coordinating mattress supporting frame, will travel in a clock-wise direction while the helical grooves 49 in the upper section 35 and the helical grooves 52 in the lower section will at the same time travel in a counter clock-wise direction to raise the said side drop panels, or vice versa.


1. In a crib, an enclosure frame, comprising end panels, corner posts, connecting cross rails and side rails, a vertically adjustable mattress supporting frame, vertically adjustable side drop panels, threaded shafts each having oppositely threaded portions rotatably mounted upon said enclosure frame in close juxtaposition to said corner posts and engaging through threaded sockets in the said vertically adjustable mattress supporting frame and the said vertically adjustable side drop panels to simultaneously and vertically move in opposite directions, the said mattress supporting frame and said side drop panels when the said threaded shafts are rotated.

2. A crib as defined in claim 1 in which a looking means is provided to manually hold the parts immovable and a foot pedal actuating means to release the said locking means.

3. A crib as defined in claim 1, in which a crank handle is attached to one of the said threaded shafts to afford a means for manually rotating said threaded shaft.

weights are included upon the said side drop panels to counter balance the excessive weight of the said mattress supporting frame and overcome the friction of the said threaded shafts in the said threaded sockets.
