Application led December 20, 1915. Serial No. 67,944.

To all whom z't may concern.'

Be it known that I, JACK ZA'rzKiN, a

citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Bed- Frames, of which the following is a specication.

This invention relates to improvements in childrens c'ribs, particularly those having metallic frames, and its principal object is to provide means whereby either or both side guard frames may be automatically locked and firmly held in a raised position or lowered by the release of the locking means from a single point.

Such object is attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this specification-,fand in which Figure l is a perspective view of a metal framed crib illustrating the application of the invention.

F ig.A 2 is an enlarged fragmental, partial side elevation and sectional view showing the construction and manner of attachment of the invention, and` Fig. 3 is a fractional, sectional view showing a modified form of locking means.

In the drawing, the numeral 10 designates the posts of the crib, the saine resting pref erabl on casters l1 in order that the crib ma e readily and easily moved about.

rnamental knobs 12 are usually supplied at the tops of the posts, having bars 14 rigidly extending between the end posts, which are also connected 'by lower bars 15.

Vertical bars 16 are engaged at their ends with the horizontal bars forming in effect stiifening elements which also operate as guards to prevent the occupant from falling over the edge of the bed and the injury consequent thereto. y

One of the sides of the crib may have permanent guards consisting of apair of horizontal bars 18 -attached to the side posts and having between them a plurality of vertical bars 19, as shown 'on the far side of the crib indicated in Fig. l, which is thus far of well known construction.

The improvement consists in rigidly affixing a pair of brackets 2O and 21, respectively upper and lower, to the side, posts 10, near the top and bottom thereof, and in such manner that the brackets extend toward the opposite end facing each other.

In these brackets are rigidly secured vertical rails 22, tubes being preferably used, arranged to stand parallel and prevented from turning by the inserted plugs 24, as shown in Fig. 2, or other equivalent means, so that the holes 25 may always be presented open toward the opposite end.

Freely slidable on the rails 22 are yokes 26 having sleeves 27 in which are rigidly engaged hollow bars 28, extending between opposite pairs, the bars being connected by a plurality of vertical bars 29 corresponding to'ghe bars 19 on the opposite side of the cri In the upper bar 28 are two slidable plugs 32 having grips 33 rigidly inserted therein and extending outward through slots 34 formed in the wall of the hollow bar 28.

Between the plugs 32, so as to normally press them apart, and opposing the grips 33, is a coiled push s ring 35, and secured in the 'outer ends of t e plugs are thin slidable rods 36, the same extending -through the' sleeves 27, in which they are guided so that the ends of the rods may register with the holes 25, in the rails 22, when the side frame is raised to its full height, engaging therein by reason of the spring 35, thus locking the frame in positionuntil released by pressing the grips 33 toward each other.

In order to prevent a child occupying the Y perforated, as at 40, in the upper front ends v in place of at the sides.

The yoke and sleeve construction remain substantially the same, as docs the tubular bars 42 extendingA therebetween. At the center of the upper bar is secured a plug 43, by the screw 44, and passing through the pl is a wire rod 45 to which is attached the inner end of the conically coiled torsion.

spring 46, the outer end of whichv is secured by the screw 44.

The ends 47'- of the rod 45 are bent at av right angle and yscrew threaded to ,receive collars 48, after which they pass out of the tube throu h slots 4:9 formed therein and engage wit handles 50 by means of which they may be rotated to an extent limited by the length of the slot.

Arms 52, extend laterall from the operating handles 50 and are 'ormed to extend so that ins 53 set therein may engage with the per orations 40 when in a locked condi tion.

ln operation, when the lard frame is in a lowered position, and it 1s desired to raise and secure the same, it is only :necessaryv to lift the frame, whereupon, when the pins 53 reach the level of the perforation they will be forced in by the action of the torsion spring 46;

ln releasing or unlocking the frame, either of the handles 50 may be raised, clearing the pin of the perforation and allowing the trame to be lowered.

As the handles extend normally downyward they are not easily accessible to the crib occupant but very convenient for op# eration by one outside the crib.

Thus it is possible for a person to operate the locking device with .one hand by a perfectly easy motion, as is also the case with the device previously described, and so far as known this cannot be done with any of the arrangements in present use.

Having .thus described my invention, what naaaeee l claim as new and desire to secure by Letters Patent, is

1. In a device of the class described, the combination with a pair of vertical rails having perforations through their walls at the outer side near the top thereor'a frame slidably engaging said rails, a tubular element in said frame, a rod rotatably held in said tubular element, said rod having bent ends extending outwardly through said element, operating handles on said rod, arms carried by said handles, said arms having means `for engagementgwith the mentioned perforations and means for exerting a torsional e'ect upon said rod, handle and arms whereby the latter are normally pressed against said rails.

2. ln a device of the class described, a pair of spaced vertical rails, a frame slidable thereon, said 'frame having an upper hollow element, of a plug rigid in said element, a rod revoluble in said plug, means combined with the ends of said rod adapted to engage in perforations in said rails, an operating means therefor and a torsion spring adapted to normally cause engagemeit between said engaging means and said rai s.

ln testimony whereof l have signed my name to this specification.

JACK aarznrn.
