Appliatin mea July 3, 192s. serai No. 64am?.

To all whom t may' concern:

-Be it known that l, LoUis FRANK, a citi- Zen of Russia, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cribs, of which the following is a specification.

The invention pertains to metal beds or cribs for the use of babiesorsmall children, and said invention comprises certain improvements, hereinafter pointed out, on the crib made the subject of Letters Patent of the United States No, 1,278,903, grantedto me September 17 1918. The crib has tall sides and ends surrounding the spring, with oneof said sides vertically slidable so that it may be lowered when desired and thereafter slid upwardly to its operative position. VThe cribs of the aforesaid Letters Patent have had a wide sale, but have possessed the disadvantage of not being, on the operation of theslidable side, noiseless. In the cribs as heretofore constructed, the apertured endsof the upper and lower rails of the slidable side, slid on vertical rods securedto the end frames of the crib, and while slidingv up and down said vertical rods created ascratchingnoise of a disagreeable nature and deemed to be objectionable, especially when a child, while asleep in the arms of .a nurse, is to be placedin the crib.

The object of thepresent invention is to so construct the slidable side of the crib and itsjcooperating parts that said side when in operation will be substantially noiseless, my invention relieving the metal surfaces or edges of the ends of the upper and lower rails of the slidable side of the crib from direct Contact with the surfaces of the metal guide-rods secured to the head and footframes and upon which theslidable side has its movements. The invention will be fully understood fromthe detailed description hereinafter presented, reference being had to the accompanying drawings, in which; Y

1 is a side elevation of a crib Iembodyingmyinvention, the slidable side of the crib` being shown in its .upper operative position byj solid lines andin lits lower positioii by dottedV lines, and in Fig. 1 the slidable side of the crib is formed o ftubular upperan'dlower herizontal rails and tubular vertical ,connecting-rods interposed between said rails;

Fig. 2 is a vertical section through a portion of the crib taken on the dotted line 2 2ofFig.-1;

Fig. 3 is a vertical section, on a larger scale, through'a portion of the crib, taken on the dotted line 3 3 of Fig. 2;

Fig. 4 is a perspective view, partly broken away, of one upper corner portion of the s lidable side ofthe crib and a felt apertured the slidable side of a crib, the guide-rod for one end thereof and the corner post, Fig 6 illustrating a modified form of the invention; F ig. 7 isa vertical section on a larger scale, through the same, taken on the dotted line 7-7 of Fig. 6;

Fig. 8 is a top view of theend of the upper rail member shown in Fig. 6, with the sound deadening vfeatures of my invention omitted; and

Fig 9 isa top view of a portion of the cribside shown in Figs. 6, 7 v and l8 and illustrates the manner of applying the felt disk to` itsreceiving cap secured on the end of theupper rail member of said side.

In Ithe drawings, 10 11 designate the head and foot frames of the crib,'12 denotes one ofthe usual side rails, and 13 the supporting spring for a mattress and bedding. The head and foot frames embody corner posts 14, 15, respectively, and between these posts at one side of the crib is the vertically Vmovable or slidable side 16 which is formed of upper and lower horizontal tubular rails 17, 18 and vertical tubular rods 19 interposed between and connecting said rails.

The corner posts 14, 15 are provided near their' upper and Vlower Iends with rigid brackets20 having horizontal members 2l, 22, respectively, in which are secured the Vertical guide rods 23, these bracketsand rodS being shown in my aforesaid Letters Patent.

.The ends ofthe upper and lower rails17,

18 of thejside 16 are vertically k z ipertured,

as at 24, Fig. l1, inline with the interior of the vertical end rods 19, and the rods 23 are extended through these openings or apertures 241 and said end rods 19 and thereby the slidable side 16 is connected With the crib and may be slid upivardly on said rods to its operative position, shown by solid lines in Figs. 1 and 2, or allowed to descend y on said rods to its inoperative position indicated by dotted lines in Fig. 1.

I provide pivoted locking dogs 25 for locking the side 16 in its upper position, these dogs being connected by a link 26 and adapted to engage brackets 27 depending from the lower rail 18 of said side 16. rlhe dogs 25 require no special description since they are shoivn in my aforesaid Letters Patent.

Inaccordance With my invention I provide the ends of the rails 17, 18 with corresponding means for preventing the meta-l at the edges of the apertures 24 from scratching against the rods 23 during the upward and downward movements of the side 16, said means being shoivn in detail in Figs. o and a and being applied to the upper surface of the ends of the rail 17 and to the lower surface of the ends of the rail 18. The means I prefer to use for preventing the metal of the side 16 from rubbing against the rods 23 consist, as shown in Figs. 3 and 1, for each aperture 241, of a felt disk 28 and a cap 29 securing said disk in position and concealing the same. rIhe disk 28 has a vertical hole 30 through it and is positioned concentrically with relation to the aperture 24, and as shown in Fig. 3, the hole 30 is smaller than the aperture 211 and snugly receives the rod 23 and thereby the edges of the aperture 24 are prevented from engaging or rubbing against said rod. The cap 29 is of metal and closely fitsk upon and conceals the disk 28, and said cap has in its top a hole 31 which is vertically above and about the same in size as the aperture 24, said hole 31 being less in size than the hole 30 in the disk 28 and its edges being prevented from engag ing or rubbing against the rod 23 by the disk 28, which is in effect a felt sleeve secured to the slidable side 16 to engage the rod 23 and keep the metal of said side out of engagement with said rod.

The cap 29 is secured to the end of the rail 17 by means of tongues 32 formed thereon and extended through slots 33 in the top of said rail and then bent laterally close under said top portion of the rail 17,

as shown in Fig. 3.

Each end of the topk rail 17 has at its upper side the aperture 24, apertured felt disk 28 land cap 29 shown `in Figs. 3 and 1, and each end of the bottom rail 18 has at its lower side the like aperture, apertured felt disk and cap to keep the rail 18 out of engagement with the rods 23.

The rods 23 are largely concealed by the end tubular rods 19 of the slidable side 16, and said rods 19 are of such proportions in cross-section that their' inner surfaces are Widely spaced from said rods.

It Will appear obviousy that the slidable side 16 will have a substantially noiseless operation When slid up and down, since vThe caps l29 are, at one side, each formed with an opening 190, and When the felt disk 28 .is squeezed on opposite sides so as to lessen its diameter, the disk may be slid through the opening 100 and into the cap 29, said disk When substantially Within the cap being pressed against at its outer end by the thumb or finger so as to round up the disk Within the cap and properly position the aperture of said disk. When the disk 28 shall have become unduly Worn by the friction of the rod 23, the disk may be removed from the cap through the opening 100 and be replaced by a new disk. I find it is important to apply the felt disks 28 to the caps 29 after the crib has been completed. When the disks are applied Within the caps and the caps secured in position on the rails of the crib-side before said side has been enameled and baked, the disks become coated or impregnated With the enamel and lose much of their eilieiency as sound deadeners. In accordance With my invention the crib side has the caps 29 secured thereto and is enameled and baked before the disks 28 are introduced into the caps 29, and hence thedisks retain all of their soft nature and act efficiently in the accomplishment of the purposes of this invention, and in addition, which is quite important, Whenever a disk becomes unduly Worn, it may be removed and replaced by a new disk.

In Figs. 6, 7 8, 9, I illustrate a modified form of slidable crib-side, and the same is numbered 35. The side 35 omits the vertical end tubular rods 19 of Fig. 3 and the ends of its horizontal rail members are iattened into disk outline, as at 36, and apertured at 37 to receive the vertical guide rods 38 secured to the corner-posts 39. Upon each disk end 36 is positioned a felt Washer or sleeve L.t0 having a vertical hole concentric with and less in diameter than the aperture l37, as shown in Fig. 7. The felt Washer 40 is held in position by a metal cap 41 which is apertured at 42' to permit the pas sage through it of the rod 38, and said cap is secured to the disk-end 36 by tongues 43 formed thereon and extended through recesses 44 in the edges of said disk end and bent under said end, as shown in Figs. 6 and 7. The construction shown in Figs. 6, 7, 8, 9 is in all essential particulars the same as the construction illustrated in Figs. 1, 2, 8 and 4 and accomplishes the same result of rendering the side noiseless when slid up and down. The side 35 differs in its own details from the side 16 and hence involves a. modification with respect to the application of the invention thereto. The caps 41 have openings 101 in one side to admit and permit the removal of the felt washes 40, as shown in Figs. 6 and 9, said openings 101 corresponding with and being provided for the same purposes as the openings 100 shown in Figs. 4 and 5 and hence requiring no further description.

What I cla-im as my invention and desire to secure by Letters Patent, is:

1. A crib of the character described having a vertically slidable side mounted on guide-rods secured to the end frames, said side having upper and lower rails apertured at their ends to receive said rods, apertured sleeves or washers of felt on said ends in line with the apertures therein and through which said rods pass and apertured caps on said sleeves or washers and substantially concealing them and having tongues bent laterally against portions of said ends and thereby securing said caps and washers in position, the apertures in said sleeves or Washers being 'of less diameter than the apertures in said ends and caps, whereby the metal portions of said side are kept from V contact with said rods and the operation of said side is rendered substantially noiseless.

2. A crib of the character described having a vertically slidable side mounted on guide-rods secured to the end frames, said side having upper and lower rails apertured at their ends to receive said rods, apertured sleeves or washers of non-metallic material on said ends in line with the apertures therein and through which said rods pass, the apertures in said sleeves or washers being of less diameter than the apertures in said ends, whereby the metal portions of said side are kept from contact with said rods and the operation of said side is rendered substantially noiseless, and metal caps litting upon said sleeves or washers and secured to the said ends of said rails and serving to secure said disks or washers in posit-ion, said caps having apertures through them to receive said rods and which apertures are greater in diameter than the apertures in said disks or washers, and said caps having openings in their sides through which said washers when laterally pressed on opposite sides may be Worked into said caps while the caps are in rigid position, thereby permitting the application of the washers after the crib-side has been otherwise completed and also the renewal of the washers when necessary.

Signed at Brooklyn, in the county of Kings and State of New York, this 28th day of June A. D. 1923.

LOUIS FRANK.
