Application filed February 24,1914. Serial No. 820,460.

To'aZZ whom it may concern:

Be it known that I, CHARLES VALLONE,.3. citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Antirattling Devices for Sliding-Side Cribs, of which the following is a specification.

This invention relates more particularly to anti-rattling devices for childrens metal cribsof that kind having sides or side ,railings arranged to slide up and down on vertical guide rods which are fixed to the end frames of the crib and passthrough guide holes or loops on the horizontal railsof the sliding side.

The object of the invention is to provide a practical and desirable device of siinple and inexpensive construction and which is inconspicuous, for preventing the slidingside from rattling on its guide rods in the use of the crib.

In the accompanying drawings: Figure l is a fragmentary broken side elevation of a crib provided with anti-rattling devices embodying the invention. Fig. 2 is a sectional plan View thereof on an enlarged scale on line 22, Fig. 1. Fig. 3 is a sectional elevation thereof on line 83, Fig. 2.

Like reference characters refer to like parts in the several figures.

A represents the upright end frames, and B one of the sliding sides or side railings of a metal crib of ordinary construction. The side B shown consists, as usual, of horizontal upper and lower rails 72 I) connected by uprights 12 and is arranged to slide on vertical uide rods O which are fixed to the end frames and pass through guide holes 0 in the ends of the upper rail and through guide holes or loops 0 at the ends of the lower rail of the side B.

As the distance between the guide rods or between the guide holes or loops atthe ends of the sliding side are apt to vary somewhat in the manufacture of the cribs, the guide holes or loops are ordinarily made sufliciently larger than the cross-section of the guide rods to enable the parts to be readily assembled and insure the free sliding of the side on the guide rods. There is, therefore, frequently suflicient play of the holes or loops on the guide rods to cause objectionable noise or rattling in the use of the cribs. This play and rattling is prevented by the following described means: D represents anti-rattling devices or springs secured to the lower rail of the sliding side and pressmg yieldingly against the guide rods C for preventing the play and rattlin g of the lower portionof the side against the guide rods. Each ofthe springs shown consists of a strip of spring metal having a broad attaching end (Z (Figs. 2 and 3) which extends along andis preferably curved to conform to the cylindrical surface of the lower rail adjacent to the loop 0 and isriveted or otherwise rigidly secured thereto. Preferably the lower rail has an integral rivet stud cl which passes througha holein the spring strip and is headed over. The spring extends from its attachedend toward the guide rod C and its free end curves 0r bends down-v wardly into the loop or hole 0' and bears yieldingly against'the inner side of the guide rod, thereby drawing the end. of the loop against the outer side of the rod and preventing the loop from rattling against the guide rod. As the spring strip lies flat upon the rail 6 and its free end enters and is practically hidden from view by the loop 0, the device is very inconspicuous and does not detract from the neat appearance of the crib. Furthermore, the free end of the spring is confined between the sides of the loop and is thus prevented from lateral displacement from the guide rod and it is practically impossible for the spring to be accidentally knocked out of position against the guide rod or broken, as would be liable to happen to a spring projecting upwardly or away from the rail. The spring can thus be securely fastened in place by a single rivet and cannot get out of place even if itshould become loose on the rivet. The device described is, therefore, exceedingly simple and inexpensive to apply to the cribs and is reliable in use and durable. The spring exerts suflicient pressure against the guide rod to prevent the loop rattling-on the rod but it is adapted to slide along the rod and not interfere with the raising or lowering of the side on its guides.

Anti-rattling devices similar to those on the lower rail can, if desired, be applied to the upper rail 1) also, to prevent the rattling of the upper portion of the side on the guide rods, but in the crib illustrated the upper rail is provided with clutches E engaging the guide rods for holding the sliding side in any position to which it-inay be raised, and as these clutches prevent play and rattling of the upper portion of the. side on the guides it is not necessary to use the antirattling springs D on the top rail. The clutches E shown consist of pivoted levers which are caused to grip the guide rods by hidden springs and they are adapted to be released to permit the lowering. of the side by pressing upwardly the inner ends of the levers. v I

I claim as my invention: v 1 l. The combination with'the' sliding side of a crib having a horizontal rail, and a guide rod on which said rail is arranged to slide, of a spring strip which is secured to and extends lengthwise of said rail and has a bent free end which bears yieldingly against said guide rod and is adapted to slide thereon.

2. The combination with the sliding side of a crib; and a'guide rod which passes through a guide hole in said side, of a spring strip secured to said'side and having a free end which extends into said hole and bears yieldingly against said guide rod and is adapted to slide thereon.

3. The combination'with the sliding side i of a cribhaving a horizontal rail; and a guide rod which passes through a guide hole strip being held'from lateral displacement by the walls of said hole.

4. The combination with the sliding sideof a crib having a horizontal rail, and a guide rod whlch passes through a gulde hole in said rail, of a spring strip having an .at-

taching portion-which lies fiat against said rail and 1s secured thereto by a smgle rivet and a bent free end which extends into said hole and bears yieldingly against said guide rod and is adapted to slide thereon, the free end of said spring strip being held from lateral displacement by the walls of said hole."
