Application lcd January 6, 1920. Serial No. 349,833.

T 0 NZZ whom if; may concern.

Be it known that I, drinn L. VENTZ, a citizen of the United States, residing at the city of Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful improvements in Conveyers, of which the following is a specification.

My invention relates to improvements in conveyers and the object of my invention is to provide a simple and convenient device of the character described.

I accomplish this object by the device illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the device Figure 2 is a side view of the device inverted, and i Figure 3 is a section of the device on the line 3-8 in Figure 1.

Similar characters refer to similar parts. throughout the several views.

In a frame comprising a plurality of longitudinal

flat bars

1, 2, 3, 1 arranged in parallel formation and a plurality of lateral spacing braces 5, 6, 7, connecting the same, l provide two parallel marginal rows of bearing rollers 8-8 of hardwood or other suitable material, and a central intermediate row of independent rollers 9, 9 of a smaller diameter than the

marginal rollers

8, 8. The rollers are preferably positioned closely adjacent each other to form a substantially continuous roller surface. The

rollers

8, 8 are mounted loosely on shafts 10 inserted through the longitudinal bars and positioned above their medial line so that the

rollers

8, 8 extend beyond the horizontal plane of the

longitudinal bars

1, 2, 3, 4 on one side, and are within the horizontal plane of said rollers on the other side to the end that the

rollers

8, 8 will form a roller bear.- ing surface for the device itself Awhen in its normal position and will serve as a roller bearing surface upon which objects may be moved when in an inverted position as shown in Figure 2. It will thus be appa-rent that when in its normal position the device may be used as a conveyer truck or movable platform and when inverted it will be stationary upon the floor and will serve as an anti-friction conveyor bearing for objects to be moved upon or over i-t.

I prefer to form the shafts 10 with a head 101 at one end to be seated against the outside face of the device and having an end section 11 projecting within the inner longitu- .for the reason that this facilitates proper lubrication and prevents friction between the shafts and the longitudinal bars. My device thus assembled will form a truck or conveyer by which objects may be readily moved and when inverted will form a roller surface with a medial longitudinal roller trough or valley extending from end to end of the device for the purpose of guiding toward the centre objects moved upon the de-v vice and to overcome the tendencyto roll toward the sides and by my improved con struction having separate roller sections in the medial trough or valley, 1 obviate the friction which would result from the use of a single cross roller of varying diameter.

The many uses and advantages of this device are obvious and require no further elucidation and modifications may be made without departing from the spirit of my invention, the novel features.v of which are more particularly set forth in the claims.

What claim is:

1. In a device of the character described the combination of a frame comprising a plurality of longitudinal bars arranged in pairs and a plurality of lateral spacing braces, spaced shafts seated in the longitudinal bars and having end sections projecting beyond the inner bar of each pair of bars, rollers mounted loosely on said shafts and a pin engaging a plurality of said shafts to prevent their rotation.

2. 1n a device of the character described the combination of a frame comprising a plurality of longitudinal bars arranged in pairs and a plurality of lateral spacing braces, spaced shafts seated in the longitudt nal bars and having end sections projecting beyond the inner bar of each pair of bars, rollers arranged in parallel rows and carried loosely on said shafts, a pin engaging a plurality of said shafts to prevent rotation thereof and rollers between the inner rows of parallel bars and mounted loosely upon llO the projecting.;` ends of the shafts and havingr a smaller diameter than that of the outer rows of rollers.

In a device of the character described, the combination of a plurality of rollers arranged in parallel rows, shafts upon Whichsaid rollers rotate and a pin inserted through a plurality of said shafts to look the same against rotation.

1L. In a device of the character described,

a frame, a marginal row of loose rollers at f the longitudinal sides of said frame, a medial row of loose independent rollers of smaller diameter, shafts carrying the marginal rollers and seated in the medial rollers and a pin inserted through a plurality of adjacent shafts to look the same against rotation.

In testimony 'whereof I affix my signature.
