,ROLLER FOR CONVEYEB$.

Application filed Ju1y 1'5, 1926. Serial No. 122,653.

: This invention relates to conveyers such as are used for carrying articles from one place in a building to another and which comprises a runway of free rotating rollers and it consists of means self contained with each roller for retarding the momentum of the roller and preventing idle spinning or rotating thereof.

The invention consists in the novel features and in the combinations and constructions hereinafter set fort-hand claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. a

Figure 1 is a fragmentary perspective view of a conveyer embodying my invention.

Figure 2 is an elevation, partly broken away, and partly in section, of one of the rollers.

Figure 3 is a cross sectional view through one of the rollers.

Figure 4 is a perspective view of a modified form of a conveyer embodying my invention.

Figure 5 is a view similar to Figure 2 of a form of a roller shown in Figure 4.

Figure 6 is a detail view of the means for stopping the momentum of the roller shown in Figure 5.

As is well known to those skilled in the art, I

in carriers embodying rollers, the rollers after an article has passed over them continue to roll or rotate so that the succeeding articles are passed along faster than and collide with the articles in front, and this happens whether or not the carrier is inclined or some of the roller-s are power driven.

In some conveyers, attempts have been overcome to prevent the acceleration ofthe movement of the articles by connecting up rollers at intervals with power or by putting various forms of friction brakes. on the V rollers.

Neither of the foregoing ways of retarding the momentum of the rollers is entirely satisfactory. v.

\ My invention consists of which the rollers have self contained means for retarding their momentum.

a conveyer in In the drawings, 1 designates the frame of the general type of conveyer embodying my invention, and 2 is the seriesof rollers, the v rollers being here shown as mounted on axles 3 supported in the frame 1. The axles are stationary and anti-friction bearings are interposed between the heads at opposite ends of the rollersand the axles 3. The axles arehere shown as mounted'in slots 5 in the frame 1 and hence capable of a sliding move ment lengthwise of the conveyer.

.The means for preventing or retarding the momentum of the roller comprises an eccentric weight fixed wi being designated 7and preferably extending the length of the roller. Obviously, the weight inside of the roller will always tend to hold the roller so that the weight is below the axes of the roller and hence to retard the momentum or stop the rotation of the roller after the article being conveyed has passed over the roller, article causes the roller to rotate.

In Figures 4, 5 and 6, a modified form of such momentum retarding means is shown" in which the weight 8 for retarding the momentum of the roller is carried by an arm 9 mounted on the axle 10, the axle 10 and the roller '11 being rotatable as a unit.

In this form of my invention, anti-friction bearings 12 are interposed between the axle" 10-and the frame 13 of'the conveyer. Also,

In testimony whereof, I have hereunto signed my name, at Syracuse, 1n the county thin the roller, this weight it being understood that such 7 of Onondaga, and State of New Yorln this j 1st day of May, 1926.
