\ TRUNDLING DEVICE.

Application filed February 3, 1925. Serial No. 6,657.

To all whom it may concern:

Be it known that we, HAROLD L. CALD- WELL and BENTON F. STITT, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Trundling Devices, of which the following is a specification.

The invention has been designed more particularly for trundlingly supporting a baby crib but is not limited to such use.

The object of the invention is to provide an improved mounting for such a wheel or caster whereby it can be readily adjust ed and fixed to occupy various positions with respect to the object it supports so as, for example, to support the object in an elevated or lowered position or with its axis below the object supported or beyond the side of such object or with itsaxis either fixed or capable of swinging with reference to the object and as'will be hereinafter more particularly set forth. A further important object of the invention is to promote cont pactness when such wheels are used in folding cribs. Other objects will appear from the disclosure.

The invention is embodied in the ex-' ample herein shown and described the features of novelty being finally claimed.

In the accompanying drawing Figs; 1, 2 and 3 are side elevations of the wheel and its mounting affixed to the corner of a screened crib, the wheel being indicated in three ofits possible different positions.

Fig. 4 is an end view, as regards the wheel mounting, illustrating in broken lines the position occupied by the wheel as shown in Fig. 3 and in full lines its appearance as shown in Fig. 4. v

Fig. 5 is anend view of the bracket or mounting with the wheel removed.

Fig. 6 is a horizontal section of the bracket on the line VIVI Fig. 4: looking up with the wheel carrying spindle in its outermost locked position. 1

Fig. 7 is a detail of the adjustable spindl alone removed.

In the views 10 designates a fraction of one corner of the crib or other object to be supported. 11 designates the wheel, it being journaled at its axis in a fork 12. The shank of the fork 12 is swiveled in a cylindrical boss 13 formed on the lower side of rotation of the spindle.

crib at a corner thereof. Said bracket 18 is bored longitudinally to receive the spindle lat; and extending transversely through the bracket is a pin 19 having a reduced portion 19, said pin having a limited longitudinal movement and pressed by a spring .20 to normally engage any one of the annular grooves 15, 16 or 17 and thereby lock said spindle from longitudinal movement in the bracket. The pin 19 is adapted to be pressed by the finger of a hand and when it is pressed sui'liciently inward to release the spindle 1 1 the latter is free for longitudinal movement in or removal from the bracket. Inv operation the spring 20, when relieved of the aforesaid spindle-releasing pressure, automatically causes the intercepting and locking of the spindle when one of the grooves 15, 16 or 17 is brought into alinement with the pin.

The bracket 18 is provided with a downward projection 21 against which the fork abuts when the spindle is shoved to its innermost, position, that is with the pin 19 engaged with the groove 17, thereby preventing the wheel from swinging at its swivel connection withthe head of the spindle. In

this position also the square head engages a notch 22 in the projection 21 that prevents When the wheel with its fork is drawn outward fro-m the projection 21 or so that the locking pin 19 is engaged with the groove 16 or the groove 15 the wheel is free to turn on its swivel. The first of these two positions can be termed the narrow gage swivel position because the two wheels at that end of the crib are closer together.

The outer end of the bracket 18 is made with a downwardly extended transverse wall 26 flanked by flanges 23, 28, said transverse wall being formed with a guide-way or seat having square corners 24 for the rectangular head of the spindle adapted to prevent rotation of the spindle on its axis. The said transverse wall 26 is also provided in its outer face with a vertical notch or groove 25 into which the inner end of the rectangular head can be shoved when first sufiiciently drawn outward and given. a quarter turn. The position occupied by the wheel when adjusted as just described is indicated in Fig. 3 and by broken lines in Fig. l. lVhen the two wheels at an end of the object supported are to occupy a broad gage relation, that is with each wheel standing in a plane beyond the side of the supported object and with the object in elevated position, or as in Fig. 4-, the spindle and rectangular head are drawn out to the position shown in Fig. 6. To make the change just referred to from the position shown in Fig. 3 the spindle l-it is released and the rectangular head withdrawn from the notch 25 when after a quarter turn of the spindle it is shoved in to engage the corners In each of these positions the locking pin 19 is engaged with the groove 17 of the spindle 1%. I

It will be understood, of course, that ordinarily one of these wheels and its de: scribed mounting will be applied to each of the four corners of the article to be supported but it is obvious that three wheels can be applied if desired.

lVhen these wheels are applied to a folding crib and the wheels turned to the posi- 'tion shown in Fig. 3 the article is very greatly compacted for shipment or storage or for rolling under a bed when not needed for use.

It will be understood, of course, that where we use the expression, standing at right angles in a claim we mean substantially that and not necessarily the geometrical connotation thereof.

The term wheel as used in our claims includes a caster or any other form of rolling member adapted to effect the result by whatever name called; and the forms of any of the parts can be changed without departing from the gist of the invention as claimed.

hat we claim is:

1. In combination with an article of furniture or the like, a trundling device therefor comprising a wheel, aframe in which the wheel is carried, a spindle connected with said frame and extending at right angles to the vertical diamater of the wheel, a bracket secured to the lower side of the article to be trundled to receive said spindle and in which said spindle can be rocked, said spindle being longitudinally adjustable in said bracket to cause the wheel to stand either in a vertical plane beyond the side of the article or under the article and means for latching said spindle with the wheel in raised position beyond the side of the article.

2. In combination with an article of furniture or the hke, a trundhng device therefor-comprising a wheel, a frame in whlch the wheel is carried, a spindle connected with said frame and standing at right angles to the vertical diameter of the wheel, a bracket secured to the lower side of the article to be trundled to receive said spindle and in which said spindle can be rocked, said spindle being longitudinally adjustable in said bracket to cause the wheel to stand either in a vertical plane beyond the side of the article or under the article and means for latching said spindle with the wheel in raised or lowered position beyond the side of the article.

3. A trundling device comprising, in combination, a wheel, a frame in which the wheel is journaled, a spindle standing at right angles to the vertical diameter of the wheel and in which said frame is swiveled, and a bracket to receive said spindle and in which said spindle is longitudinally adjustable and spring actuated means for latching said spindle in the position to which adjusted.

i. A. triuidling device comprising, in combination, a wheel, a frame in which the wheel is journaled, a spindle standing at right angles to the vertical diameter of the wheel and to which said frame is swiveled, a bracket to receive said spindle, means whereby sa'd spindle may be fixed in different positions in said bracket and a stop on said bracket to prevent horizontal oscillation of the wheel carrying frame when the spindle is at the innermost of its positions.

5. A trundling device comprising, in com bination, a wheel, a frame in which the wheel is journaled, a spindle standing at right angles to the vertical diameter of the wheel and to which said frame is swiveled, a bracket to receive said spindle and in which the spindle can be adjusted longitudinally and rockedon its axis, means for ii ing the spindle in adjusted position, and means for locking said spindle from rocking on its axis whereby said wheel may occupy a raised or lowered position.

6. A trundling device comprising, in combination, a wheel, a frame in which the wheel is j ournaled, a spindle'standing at right angles to the vertical diameter of the wheel and to which said frame is swiveled, a bracket to receive said spindle and in which the spindle can be adjusted longitudinally and rocked on its axis, means for fixingthe spindle in adjusted position, means for preventing thehorizontal oscillation of the wheel carrying frame at an inner position and means forlocking said spindle from rock ing on its axis at an outer position whereby said wheel may occupy a raised or lowered position.
