3 Claims.

My invention relates to hand trucks and particularly to hand trucks of the horizontal multiple shelf type each adapted for supporting and transporting a plurality of tray or rack units in relatively lixed relation to each other, and to the truck, in a, manner permitting independent removal of any one of the trays from the truck without disturbing trays above, below, or at either side thereof.

Some of the objects of the invention are, to provide a truck of this type which is simple in construction, rugged, and particularly adapted to save time and facilitate the transportation and handling of yarn packages and racks therefory in connection with the operation of braiding machinery.

With these and other objects in view, which will become apparent from the following detailed description of an illustrative embodiment of my 20 invention shown in the accompanying drawings, the invention resides in a truck having therein the novel elements, features of construction and arrangement of parts in cooperative relationship as more particularly pointed out in the claims.

In the accompanying drawings:

Fig. 1 is a side elevation of the truck;

Fig. 2 is an enlarged sectional plan view taken on the line 2-2, Fig. 1;

Fig. 3 is a transverse section taken on the line 3-3, Fig. l; and

Fig. 4 is a perspective view of a detail of the invention.

The truck, as illustrated in the drawings, is particularly adaptable for carrying yarn package, bobbin or spool racks or trays of the type disclosed in the applicants United States Letters Patent No. 1,966,247 granted July 10, 1934, which comprises a substantially fiat rectangular skeleton frame I, provided with a plurality of rows of laterally spaced posts 2 adapted to enter center openings in yarn packages 3 for respectively supporting the yarn packages, spools, or bobbins 3, in vertical positions on the trays I.

The truck comprises, in the present instance, a substantially rectangular horizontal base I0 in the form of an open framework including longitudinal side beams II, II and transverse end beams I2, I2, preferably constructed of wood, which are secured together at the corners of the 50 base lo.

Extending vertically from the four corners of the rectangular base IU are upright shelf-supporting posts I3, I3 and I4, I4 respectively, of relatively heavy wood; and extending vertically from each of the side beams II, II, intermediate the rear uprights I3 and the front uprights I4, are relatively thin metallic uprights I5 which are provided with footing elements I6 resting on .and secured to the side .beams II, I! respectively.

Secured to the inner transversely extending faces of each of the corresponding pairs of end uprights I3 and I4, and to the oppositely disposed transversely extending faces of the pair of intermediate uprights I5, is a series of transversely extending vertically spaced bars Il, Il, the vertical spacings of which are similar in each instance, and thereby positioning the bars I1 in horizontally aligned series, respectively disposed in vertically spaced horizontal planes.

Secured to each bar of each of the horizontally aligned series of transversely extending bars I'l, Il, at each side of the truck, is a longitudinally extending bar I8, in the present instance in the form of an inverted channel bar having its weo I9 secured to the under sides of the bars Il and its flanges 2D, 20 projecting downwardly therefrom.

Secured to the longitudinal bars I8, I8, and extending transversely of the truck between the end and intermediate uprights I3, I5, I4, are transverse bars 2I, 2|, which, together with the bars I'I, Il and I8, I8 constitute a plurality of vertically spaced horizontal shelves 22, 22 each adapted to support a plurality of trays I, I.

The transverse bars I 1 and 2| provide tracks or rails for supporting the trays I, I, the bars I'I each having a single horizontal flange or traysupporting rail I'Ia. The intermediate bars 2I are each provided with a pair of horizontal traysupporting flanges or rails 2Ia, 2 Ia.

Extending vertically from the tray-supporting rails I'Ia of the bars I1, and from, and between the oppositely disposed tray-supporting rails 2 Ia., 2Ia of each of the intermediate bars 2l, are guide rails Ilb and 2I'b respectively, which guide the trays into and out of the truck, transversely thereof, and which separate and hold the trays against relative movement with respect to each other and with respect to the truck longitudinally of the truck.

At the opposite ends of each of the cooperating tray-supporting rails I 1a, I'Ib and 2Ia, 2IlJ` of the bars I1 and 2 I, respectively, are stop flanges or bumpers I'Ic and 2I'c, respectively, which ex.- tend transversely of the bars and prevent longitudinal movement of the trays I laterally of the truck.

As shown in Figs. 1 and 4, the guide rails I'Ib and 2 Ib project above the top edges of the stops Ilc and 2 Ic for guiding the tray into the pockets transverse axle 3I carried by bearings or brack' ets 32 secured to the side beams II, II. Y The truck is provided, at the front end, with a pair of wheels 35, 35, mounted in castor frames" 35, 3S, which are swiveled in bearings 31, 31 secured to the base I 0 in the angles between the side beams II, II and end beams I2, I2 thereof,

respectively.

The front end of the truck, in the present instance, is provided with a transversely extending handle bar 4U carried at its opposite ends in bearings 4I, 4I secured to the uprights I4, I4 respectively.

Of course, the truck specifically shown and described can be changed and modied in various ways without departing from the invention herein disclosed and hereinafter claimed.

I claim:

1. In a rack adapted to support bobbin spindle trays of the type having a base providing with its end members, handle means within the confines of each of said trays at each end thereof, the combination of a series of shelves, four uprights mounted for mobility within which said shelves are built, said shelves comprising a plurality of longitudinally extending vertically spaced horizontal bars, a series of transversely extending horizontal cross bars mounted on said longitudinal extending bars, said last named bars together providing pockets for the reception of bobbin trays, and undercut means at each end of the transversely extending bars facilitating initial guiding of bobbin trays to the pockets, said transversely extending bars providing means shelves, of mobile mounting means therefor,

means for initially and finally guiding and forming ypockets for said bobbin spindle trays comprising cross bars adapted to be mounted in spaced relation on said longitudinally extending bars and provided with supporting means and guiding means positioned vertically with respect to said supporting means, end members located vat each end of said bars and having a height less than the height of said guiding means thus providing an additional initial guiding means for receiving said bobbin spindle trays.

3. In a rack adapted to support bobbin spindle trays and the like of the type having a base provided with openings adjacent its end members which facilitates grasping of the end members as handles, the combination of a series of shelves comprising a plurality of horizontally arranged inverted channel bars extending longitudinally of the rack, a plurality of uprights for supporting said shelves, a plurality of cross bars mounted 0n said longitudinally extending bars in such relation that their ends overhang at least some of the outermost longitudinally extending bars, thereby providing open spaces between said cross bars to facilitate grasping of the handles provided by the end members of the bobbin spindle trays, said cross bars also being provided with guide rails and end stops for said trays at both end of said rails of a height less than said guide rails, for effecting initial guid ing of the trays upon insertion thereof to the pockets formed by said cross bars.

HENRY JANSSEN.
