Application filed June 5,

To @ZZ whom t may concern:

Be it known that I, CHARLES W. WAL- srRoM, a citizen of the United States, resident of Minneapolis, county of Hennepin, State ol Minnesota, have invented certain new and useful Improvements in Cribs, of which the following is a specification.

My invention relates to that class of cribs in which one side is arranged to move vertically, being lowered for convenience in making upthe bed or placing a child therein, and raised when the crib is in use to prevent the child from accidentally falling out.

A further and particular object is to provide a supporting means for the side of the crib which will permit it to be easily and quickly raised'or lowered without the use of bolts, latches or spring-actuated devices of any kind.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a perspective view of a childs crib embodying my invention,

Figure 2 is a detail view, showing the side of the crib, raised or lowered position being indicated by dotted lines,

Figure 3 is a similar view taken on a line at right angles substantially to the view- 4 4 of Figure 2.

Figure 4C is a sectional view on the line M of Figure 2,

In the drawing, 2 represents the end rails of the crib, 3 the posts or legs supported by suitable casters, 4 the fixed side of the crib and 5 and 6 the. top and bottom rails of a movable side connected by spindles 7. The legs 3 on that side of the crib have upright rods 8 secured thereto, the lower ends of the rods being bent at an angle, as indicated at 9, and inserted into the legs a suitable distance, providing a space between the rods and the surface of the leg.

At the top the rods are bent to form a loop 10 substantially U-shaped, one arm of the U having its end inserted into a socket in the post at 11, thereby supporting the upper end of the rod and holding it in its proper position with respect to the leg. The

1922. Serial No. 566,025.

rods are bent outwardly, as shown in Figure 3, from their middle portion toward their top, so that the end of the loop will be in the middle of the leg in alignment substantially with the lower end so that when the side of the crib is raised to its supporting position, the two sides will be in the same relative position with respect to the ends of the crib and present a neat symmetrical appearance.

The rails 5 and 6 have longitudinal sockets 12 in their end portions and bolts 18 fit loosely within these sockets and have eyes 14 to receive the rods 8 and slide vertically thereon.

Near the middle of the rods I prefer to provide a stop 15 preferably of rubber, which forms a rest for the eye-bolt of the upper rail and at this point a suitable connection 16 is provided between the rods and the legs and thereby the middle` portions of the rods will be braced and supported.

When the side of the crib is in its lowered position, the upper bolts will rest on these stops, as indicated in Figure 1, and when the side of the crib is raised, the upper eye-bolts will pass over the loops in the upper ends of the rods, the bolts turning in their sockets to permit this movement and when the bolts have passed over the U-shaped loops, they will rest upon the ends inserted into the legs at that point and thereby the side of the crib will be held in its raised position and it will be imposible for it to become loosened and fall unless the side is first raised so that the upper bolts will pass over the U-loops, and this raising movement can not possibly be done by a child in the crib and there will, therefore, be no danger of the crib side becoming accidentally loosened and falling and permitting injury to the child.

It will be noted from an examination of Figure l that a relative longitudinal movement of the eye-bolt shank and the crib side is permitted and this is essential to the successful operation of the device, for it allows the eye-bolt to follow the curves of the guide rod without any danger of binding or cramping thereon. Furthermore, should the rod at any time become slightly distorted or bent out of its proper position, the eye-bolts will still be free to follow the rod without interfering in any way with Lmaking of the crib bed.

I am able with this arrangement to eliminate all spring latches or other devices which arel unreliable and may easily get out of order. i

I claim as -my invention:

1. The combinationwith a crib, of vguideI rods mounted thereon and having loops Y formed therein, a crib side having sockets,

eye-bolts mounted to slide on said rods and having Shanks to enter said sockets, said cribside and said shanks having a Vrelative i longitudinal movement to allow said bolts to follow said guide rods without binding or cramping thereon.

2. The combination with a crib, of guide rods mounted thereon and having loops formed therein, a crib side having upper and lower rails and longitudinal sockets in the ends thereof, bolts having eyes to slide on said rods and Shanks fittingloosely within the sockets of said rails,l said rails and said shanks having a relative Ylongitudinal movement to prevent binding or cramping of said bolts on said guide rods.VY

3. The combination with a crib, of guide rods mountedY thereon and having loops -ormed therein, a crib side, eyebolts mounted to slide on said rods and having Shanks mounted in said crib side for relative'long tudinal movement with respect thereto whereby binding or cramping of said bolts onsaid guide rods is prevented. Y Y Y In witness whereof, I have hereunto set my hand this .31st day o May, 1922.
