(Cli-2'14--85) '1 Claims; 1

This invention. relates generally to equipment for handling rugs and linoleum, and more particularly to a transfer car comprising an. elongated wheeled; frame: with. elongated: roller mechanisms mounted thereon and adapted to receive rolls, the car including means for facilitating the. loading of. the rolls thereon and specially designed bearings for the rolls.

A further object of this invention is to provide atransfer ca which may be conveniently used to transport rugs and linoleum, the device. being particularly adapted. for use by furnture dealers in transferring carpets, rugs and linoleumsto' and from wall racks or moving the same toward and a-Wy from a cutting table.

Another object of this invention is. to provide a transfer car of this character, by means of which one or two men may conveniently handle heavy rollsof material, a. special ramp structure being provided to facilitate the rolling of the rolls onto the frame, and the same ramp structure being adapted for pivoting one set of rolIs upwardly, whereafter the car may be pushed or pulled to move the material as desired. 7

Still. another object of this invention is to provide a device of this character which can'he con veniently stored, as under a cutting table.

Another object of this invention is to provide a car of this character which may he used" to transport rolls of lengths shorter and longer than the car per se.

A further object of this invention is to provide a novel bearing construction for the rollers}, this special bearing means being adapted to provide anti-frictional terminal support for" the rollers and to overcome end thrust of these" rollers in a very simple manner.

And a last object to be specifically mentioned is to provide a' device of this character which is relatively inexpensive and practicable to manufacture, extremely simple to use under varied conditions, and which will give generally efiici'ent and durable service. I

With these objects definitely in View, together with other objects which will appear as this? description proceeds, this invention resides inlcertain novel features of construction, combination and arrangement of. parts. and portions as. will. be hereinafter described. in detail. in the specificattion, particularly pointed out in the appended claims, and illustrated inv the accompanying drawings which. form a material part-of this application, and in which:

Figure 2 is a transverse cross-sectional view, taken on. the line 2'--2 in. Figure 1 and including an end elevational view of a wall rack, the figure also including a plurality of carpet rolls, one of which. is beingv unloaded from the car onto the wall rack;

Figure 3 is an end elevational: view of this transfer car, the; figure including. a carpet roll mounted on the car and. cablemeans used: to pull the car;

Figure. 4 is a; central transverse. vertical sec.- tizona'l view of the car with one of the roller assemblies in lowered position. as when. a carpet roll is being loaded: thereon, the figure showing newrigidlramp members are used for guiding the roll onto the car, the carpet roll being shown in lines partially loaded. position and the said roller assembly being shown: in: dash. lines in the: position assumed after such loading has been completed;

Figure 5 is an enlarged detailed fragmentary View showing a. front elevation of the car with one: of the ramps: in. place as when the car'is being loaded;. and a portion of one? of. the rollers being broken away and the underlying: parts being shown. in" section and? in elevation;

Figure 6 is a. perspective view of one of the ramp members;

cation and throughout the several views of the,"

drawings;

Referring. now" to the drawings in. detail, it will be: observed: that this inventionv is adapted to. be used with. an environment. including. a wall rack, generally indicated by" the? numeral HI and com"- priseda of uprights-z I2 with rollers; lz isupported in; suitable bearings, not showmand designed for operation bya crank it-, the:'wa1]; rack. being: designed to receive rolls of carpet, rugs and linoleum illustrated. at it, Figure: 2 illustrating how a; roll: is transferred from the car whichforms theisubiect. matter'of this? invention to one of the rollers. I4.

Thetransfer car includes a' frame constructed of. elongated side: members 20' and: end members 22, both of which are preferably constructed of angle: iron welded together atthe corners, as indicated at 24. This frame is provided with casters 26 so that the car may be conveniently pushed or pulled along the floor of the store or other establishment.

A pair of end plates 28 are rigidly secured, as by bolts 39, to the end frame members 22. The roller assemblies are pivotally secured to the plates 28 and each assembly includes a pair of similar arms 32 and SA, pivoted at one end to the plates 28 by bolts or rivets 36 and carrying rollers 38 and 40 terminally mounted thereon by means of special bearing members to be hereinafter described more fully. Each roller assembly also includes headed pin members 32 rigidly secured near the upper ends of the arms 32 and 34, these members s2 being adapted to be received in recesses M:- in the braces 36 which are pivotally secured to the end frame members 22, as indicated at 48. It will be readily understood-that-- these braces iii are used to support the roller .assemblies in the positions illustrated in Figure 1.

One of the pairs of arms, that indicated at 32, is provided with u-shaped brackets 5e and a pair of ramps 52 are insertable in these bracket members as, after a manner indicated in Figure 4, it being understood that these ramps 52 may be slid within the brackets, when it is desired to shorten the effective length thereof, or when it is desired to merely store the ramps in these brackets when the device is not being used. ,The outer ends of these ramps are curved downwardly to contact the floor, as indicated at 5 and it should be particularly noted that these ramps 52 also function as hand levers, whereby the arms 32 may be raised or pivoted about the pivot points 35, in order to lock a roll i8 in the car, that is, in order to raise the arms 32 sufficiently to allow the corresponding braces #16 to be inserted so as to support the said arms 32 in elevated positions.

The special bearings for the rollers, illustrated in Figures 5, '7 and 8, are illustrated as adapted for use with rollers 38 and it which are tubular.

Each bearing assembly includes an outer bear.- ing member as which is welded to the roller, as

indicated at 58, and an inner bearing member 60 carried by a bolt 62 which is rigidly secured to the arm 32 or 35. In the preferred form, the head of this bolt 8% is welded to the said inner bearing member 66, and a spacer $5 is provided between the inner bearing member 53' and the member 32 or 34, while a nut 68 is used to tighten the assembly on the said arm 32 or 34.

Finally, the plates 28 and the side frame members are supplied with eye members it, to facilitate the securement thereto of cables 12 whereby the car may be pulled in order to transport the rolls I8 as desired.

The operation of this invention will be clearly understood from the foregoing description of the mechanical details thereof, taken in connection with the recitation of the objects sought to be achieved by this invention. In recapitulation, it may be added that the special bearing construction has been found to provide maximum freedom of rotation for the rollers 38 and 40, while satisfactorily preventing binding of these rollers due to transverse movement of the arms 32 and 34 relative to the frame of the car, all without unduly complicating the structure of these bearings. The dual functions of the ramps 52 and the general simplicity of construction of the whole device will be now seen to be important features of this invention.

Many'minor variations may be made in the exact construction and proportionment of various parts of this invention and the accompanying drawings should be considered as illustrative rather than limiting when considered in connection with the specification. Accordingly, this invention should be limited only in accordance with a proper interpretation of the terminology of the appended claims.
