SWIVEL-SUPPORT FOR GRAlN-SPOUTSf SPECIFICATION forming part of Letters Patent No. 512,394, dated January 9, 1894. Application filed September 27, 1892. Serial No. 447,027. (No model.)

To all whom it may concern:

Be it known that I, DIGHTON A. ROBINSON,

of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Swivel-Supports for Grain-spouts, of which the following is a specification.

My invention relates to means for pivotally supporting the upper end of a grain spout, and in particular to such ,a support arranged in connection with a track from which the same depends.

The object which I have in view, is to prevent the binding of one part of the spout upon the other, or its support whereby its movement is rendered easy.

The simplification of the swivel joint is a further object.

To this end my invention consists in general in the construction and combination hereinafter described and particularly pointed out in the claims, and will be more readily understood by reference to the accompanying drawings, in' which Figure 1 is a side elevation of adevice em bodying my invention, in which the track is shown in section. Fig. 2 is a vertical section on the line 00-00 of Fig. 1. Fig. 3 is a sectional view showing a modification.

As shown in the drawings, 2 represents a section of a circular, oblong or straight track upon which the lower part of the grain spout is to be supported. For this purpose I provide the loop hanger having the flat part 3,

to which the grooved rollers 4 are secured by the bolts 5. These rollers are prevented from jumping the rail by the stud bolts 6, projecting from the sides of the loop underneath the rail. From this point down the ends of the strap are turned at right angles to the upper part thereof and the ends split into the outwardly curved legs 7, which firmly hold the ring 8 to which they are fastened by the short bolts 9. At quarters on this ring are thestud bolts 10 projecting through the same to receive the anti-friction rollers 11, which rollers project up into the annular groove 12 on the overhanging part of the cast iron hop per end or cap 13 of the main spout 14, fastenedto the lower end of the cap by rivets and the rings 15. The expanded hopper top of this head is adapted to receive the lower end of the upper section of the grain spout and from its conical shape to make a tight joint therewith to prevent the scattering of grain or dust at this point.

A modification of the above design is shown in Fig. 3 in which the ring 8 has a somewhat different form from the groove 16. The overhanging part of the head 13 has a similar groove 17 and within their walls are a number of balls '18, making up a ball bearing in place of the rollers shown in Figs. 1 and 2. I thus provide a joint in which there is but little friction and which owing to its cone hopper is adapted for use with any of the ordinary sizes of grain spouts.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the track, of the loop hanger, with the rollers mounted thereon to run on said track, the split ends of said loop, a ring attached thereto, the spout, the head thereof provided with the overhanging part, and anti-friction bearings provided between said part and said ring, substantially as described.

2. The combination, with the track, of the loop hanger having its upper part parallel with the track, the grooved rollers 4. mounted on said hanger to run on said track, the ring 8 secured upon the ends of said loop, the stud bolts arranged in said ring, the rollers 12 arranged on said bolts within the ring, the hopper cap or head 13 having the annular grooved shoulder to engage said rollers, and the sheet metal portion of the spout attached to said cap or head, substantially as described.

3. The combination with the elevated track, of the loop hanger having its upper portion parallel with said track, grooved rollers arranged upon said upper portion, the studs 6 projecting from the lower portions of said pipe extending downwardly from said head,- loop beneath said track to prevent saidpulsubstantially as described. 10 leys from rising thereon, the split lower ends In testimony whereof I have hereunto set of said loop, the ring secured between the my hand this 19th day of September, 1892.

same, the anti-friction devices arranged upon DIGHTON A. ROBINSON. said ring, the spout head 13 having the out- In presence ofwardly projecting annular shoulder, adapted F; S. LYON,

to rest upon said antifriction' device and the C. G. HAWLEY.
