TRUCK ATTAOIIlvZEIIT FOR SHOEBACKS.

Application filed. March 17, 1922.

To all whom, it may concern:

Be it known that I, Fawn H. Linn, citizen of the United States, residing at South Braintree, in the county of N or folk and State of Massachusetts, have invented new and useful Improvements in Truck Attachments for Shoe Racks, of which the following is a specification.

This invention relates to racks used in shoe factories to support a plurality of partially completed shoes, and transport the same to the different locations where successive operations are performed on the shoes.

The f *ame of a shoe rack includes spaced apart longitudinal members connected by transverse members to form a. rectangular frame base, and shoe-supporting shelves or rack elements located at different heights above the base, there being an open space bounded by the base below the lowest shelf. The base is provided at its four corners with casters, adapted to roll on a floor. The wheels of these casters are necessarily of such small diameter that they do not roll easily when the rack is heavily loaded. Moreover, the wheels are liable to be clogged by dirt taken up by them from the floor.

My invention is embodied in an attachment which includes a pair of angle bars, adapted to be bolted to the said longitudinal frame members, and stiffen or reinforce the latter, one of the webs of each angle bar projecting downwardly below the frame memher to which it is attached, a transverse axle engaged with the downwardly projecting webs, and auxiliary wheels mounted on said axle between the angle bars, the diameter of the auxiliary wheels being such that they are adapted to roll easily on the floor and support the casters above the floor, so that the rack may be supported wholly by the auxiliary wheels when it is being transported, the auxiliary wheels being arranged to enter the space between the longitudinal frame members, so that the said wheels may be made of relatively large diameter, without objection ably elevating the rack, or in other words, without objectionably inclining the rack when it is at rest, and supported by two of the casters and the auxiliary wheels.

Of the accompanying drawings forming a part of this specification,

Figure l is a side elevation of a portion of a shoe rack provided with an attachment embodying the invention.

Serial No. 54,605.

igure 2 is a section on line 22 of Figure 1.

Figure 3 tachment.

The same reference characters indicate the same parts in all of the figures.

In the drawings, 12, 12 represent the longitudinal frame members of a shoe rack, the same being spaced aiart and connected by transverse members not shown, the longitudinal and transverse members co: tituting a rectangular frame base which bounds a space below the lowest shelf or racl: member 13. There are usually three or more of the members 13, these being supported by uprights 14:, secured to the base members of the frame in any suitable manner.

The raclris provided with the usual casters 15, located at the corners of the frame base.

A rac includ ng the parts above described is common and well known. Each of the members 13 is adapted to support a plurality of shoes and lasts associated therewith, in a well known manner.

My improved attachment includes a pair of straight angle bars, each composed of an upper web 16, seated on the under side of alongitudinal frame member 12, and secured thereto by bolts 17, and a lower web 18, projecting below the upper web, and provided with a bearing 19, for a transverse axle 20, the bearing being provided by forming an orifice in the lower web.

Mounted and laterally confined on the axle is a perspective view of the at- 20, are two auxiliary wheels 21, arranged to project into the space between the frame members 12. This arrangement enables the wheels 21 to be made of relatively large dianieter, so that they may roll easily on a floor, and support the rack with the casters '15 raised above the floor, as shown by Figure 1, so that when the rack is being transported, it is supported wholly by the auxiliary wheels. The axle 20 is preferably prevented from longitudinal movement by cotter-pins 22, inserted in their end portions, and hearing on the outer sides of the webs 18. The wheels 21 are preferably confined laterally on the axle by the contact of their hubs with the webs 18, and with the ends of aloose sleeve 23 placed on the axle between the wheels.

It will be seen that by arranging the auxiliary wheels 21 so that their upper portions may project into the space between the longitudinal frame bars 12, I am enabledto make the wheels of such large diameter that they are adapted to roll easily on the floor, without objectionably raising the rack above the floor, and without causing an excessive longitudinal inclination of the rack when it is at rest and supported by the auxiliary wheels, and by the two casters at one end of the rack.

-The angle bars are sufiiciently elongated to stiffen and reinforce the frame members 12, and prevent the ends of the rack from sagging under the weight of the load, when the rack is being transported, and is wholly supported by the auxiliary wheels.

The rack requires no adaptation other than the boring of holes in the members 12 for the reception of the bolts 17, the angle bars be- .ing provided with bolt holes 24c to receive said bolts.

I claim: a A shoe rack comprising a base portion, including spaced apart longitudinal frame members, and having casters at its opposite ends, a pair of straight angle-barscomposed w apart, the diameter of the wheels being such that they project upward into the space between the longitudinal franie members, and downward to support the rack with its casters raised above a floor, the length of the an glebars being such that they reinforce the longitudinal frame members, and prevent the rack from sagging at its end portions, when supported wholly by the wheels. c

In testimony whereof I have aifixed my signature.

FRANK HLLINK.
