LAUNDRY RACK.

Application filed June 16, 1927. Serial No. 199,283.

My invention relatesto new and useful improvements in laundry 'acks, and has foran object to provide a rack thatwill be efficient in service, cheapto construct, and simple to assemble.

As is well known to those skilled in the art, diiicrent forms of revolving racks are used in commercial laundriesyso that the clothes may be placed in bagsornets and placed on the racks, there gencrallybeing a small card with indiciathereontodesignate the contents or ownership of the different bags or nets of clothes, these different cards being placed with the respective bags on cer- It is desirable to have theracks revolve so that time may be saved when placing the dillerent bundles on the rack, as "if the rack did not revolve, it would be necessary for the operators to keep encircling these racks or supports.

The racks, as a rule, are rather large in ci rcun'iference, often being six feet in diame ter, and it is desirable, therefore, to have a rack that may freely revolve and atthe same time bestrong enough to support the weight of the great number ofbags that will be placed thereon.

One of the principal objects, therefore, is to provide a relativelystrong rack, which may bc'made up of a plurality of simple castings and a number of small. bars together with one circular sheet of metal, all of the parts being relatively cheap to manufacture and easily assembled by an ordinary/19incchanic. 8 1

With these and other objectsin view,the invention 1 consists in certain new and novel arrangements and combination ofgpartsas will be hereinafter more fully described and pointed out in the claims,

Referring to the drawings,

Fig. l. is a vertical sectional view;

F 2 is atop plan of the rack;

Fig. 3 is a vertical. sectional view showing a slight modification; and

Fig. l is a top plan view of theconstruction.

Referring now more in detail to the drawings, and to Figs. 1, 2 and l in particular, there is shown a tripod formed of three separate legs 1, which may be castings ormay be of pressed metal, and are bolted to a small casting 2 whiclr forms a bearing or support forthe metal shaft 3, which is supposed to tightly fit within this base 2.

About this central shaft are positioned two wheels 4 and 20, audit is the simple construction of these rack wheels that forms one of the principal parts oflthe present invention.

As heretofore mentioned, these rack wheels are relatively large, and it isdesirable to have them as strong as possible, and at the same time as inexpensive as possible, to meet with theordinary business competition.

Referring now toFigs. l and 2,1't will be seen that the rack wheelconsis'ts of a lower circular hub 5, which is preferablynan iron or steel casting, while extending radially therefrom are the integral lugs 6, which lugs also extend at an angle to the body of the hub. As may be seen in these Figures 1 and 2, they are upwardly inclined so that the brace bars or compression members 7 may be riveted or bolted thereto. These hubs willbe made up in large quantities, as there will be two of them foreach complete rack.

This hub 5 has its counterpart or upper hub 8, but in this instance, the hub 8 is provided with radial lugs 9 extending at right angles to the body of the hub, so that spokes 10 may be bolted 0r riveted at their inner ends to the lugs 9, and extend in a horizontal. plane.

The rack wheel 4 also consists of a rim formed of a circlillar band of steel 11 which is from 6 to Sinches in height, and riveted about its inner periphery are the small castings 12, having a vertical portion 13, the right angular lug 14 and the tangential lower lug 15; the angle of this lug 15 corresponding to thenngle of the lug 6 of the lower hub. After these castings are riveted to the steel band, the brace rod 7 will be riveted or bolted to the respectivelugs 6 and 15 of the hub 5 and castings 12. These brace rods form the compression members to rigidly support the rotatable wheel 4.

The spokes or tension members 10 are riveted at their inner end, as heretofore mentioned to the lugs 9 of the upper hub 8, while their outer ends are riveted to the lugs or flanges 14 of the castings 12, to thus complete the formation of the wheel proper.

Secured to the outer periphery of the band 11,"which is 'actually'the rim of the wheel, there is shown a pluralityof hooks or arms 16 which may be bolted to the rim 11 or may be fitted with bayonet lugs to fit within bayonet slots (not shown) withinthe rim so that the hooks may be quickly removed if desired. Above the lower wheel 4 on theshaft 3 is secured an adjustable collar 17 so that the second wheel 20 may be assembled like the previous wheel, and slipped over the shaft or central support 3, so that this wheel in turn may be revolved by the operator when hooking the different bags on the hooks.

A hub cap 18 may then be placed on the upper threaded portion of the shaft 3.

As far as the specification hasproceeded, it will be seen that besides the central shaft 7 and its legs, there are two wheels, each of which consists of simply a circular band, an upper and lower'hub, a plurality of small castings, andthe compression and tension members, all of which parts may be quickly I which there is fitted the thrust ball bearing '30,. so that the supporting shaft 31 may rest therein and revolve freely within the hub 27 of the casting 26.

In the first form described, it will be remembered the shaft 3 is tobe fixed, and the two wheels 4 and 20 were adapted to be rotated about the shaft. In the form now being described, the shaft 31 is to be rotatably mounted and the two rack wheels 32 and 33 are to be provided with set screws 34 so that the two wheels may be revolved in unison with'the shaft 31, or if these set screws are loosened, either wheel is free to rotate thereon.

The wheels 32 and 3.3 with the exception of the-set screwsinthe lower respective hubs are identical with the wheels 4 and 20 of the rack shown in Fig. 1. r

The only major difference, therefore, is the construction of the housing at the bottom of the rack, so that the shaft 31 may be free to tension members, and the inner em s rotate and thus permit the wheels to rotate in unison or the set screws may be loosened so that the wheels may be revolved inde pendently of the central shaft.

From the foregoing it will be seen that I have designed a large rack capable of supporting the heavy load that will be placed upon it and at the same time, I have provided a rack wherein the assembly consists of simply riveting or bolting the tension and compression members to small castings that are in turn secured to a rim, and further providing an upper and lower hub with certain lugs thereon to which lugs are secured respectively the inner ends of the s okes or i of the compression members.

I am aware that there are many difl'erent forms of wheels, but the present racks are exceedingly simple to assemble and necessitate but few parts to be bolted or riveted together by an'ordinary mechanic.

Many slight changes might be made with outin any way departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A laundry rack comprising a base, a central shaft rotatably mounted in the base, two wheel racks rotatably mounted on said shaft and means for locking each of them to said shaft, each of said wheel racks comprising a relatively wide flat metal rim, a plurality of castings secured to the inner periphery of the rim and said castings extending across the inner face of the rim and said castings provided with horizontal upper lugs and inclined lower lugs, an upper and lower hub for'each wheel, the upper hub having horizontal lugs and the lower lug having 11 )ward- 1y inclined lugs, spokes fastened to the lugs on the upper hub and to the lugs on the castings, compression members secured to the lower lugs of the casting and to the similarly inclined lugs of the lower hub and the rim adapted to receive supporting hooks.

2. A laundry rack comprising in part a wheel formed of a circular fiat metal band, an upper hub, a plurality of arms fastened on the inner periphery of the band and each arm provided with a horizontal lug and a downwardly inclined lug, an upper hub having lugs extending in the same plane as the upper lugs on said arm and a lower hub having lugs inclined similarly to the inclination of the lower lugs on the said arms, compression and tension members respectively bolted to the upper hub and the upper lugs on the arms and the compression members extending from the lugs on the lower hub to the lower lugs of the said arms and bolted thereto, and the rim adapted to have hooks bolted thereto.

3. A fabricated metal laundry rack compositioned rim, means in the form of tie arms boltcdto the inner surface of the rim, said 1 compression and tension members also bolted to said means and the rim adapted to have supporting hooks bolted thereto.

In testimony whereof I a'fiix my signature.
