BLOWER-PIPE FOR GRAlN-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 718,522, dated January 13, 1903.

Application filed August 9 1901. erial No. 71,464. (No modeLl To all whom, it may concern:

Be it known that I, JOSEPH RIESTER, a citizen of the United States, residing at Newtown, in the county of Fountain and State of Indiana, have invented certain new and useful Improvements in Blower-Pipes for Grain-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates 'to blower-pipes for grain-separators. Its object is to provide a telescoping blower-pipe which may be quickly operated with small power and simple transmitting-gear.

To this end it comprises, essentially, telescoping tubes, guides for cables, a drum, and a cable or cables connecting the several parts and applying the power.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a part of a blower-pipe; and Fig. 2 is a plan, partly in section.

In the drawings, 1 represents the larger or female member of the pipe, and 2 the smaller or male member. Fixed to the part 2 is a ring 3, and connected to this ring by a rod 4; is another stationary ring 5. The ring 5 forms at the top, in effect, a stanchion, to which is secured a beam 7, preferably of wood, having a cable-guide channel 8 and secured at the 0pposite end to the ring-stanchion 9. In the ring-stanchion 3 is journaled a drum 10, forming, with the handle 11,a Windlass. Journaled in the separated arms of the stanchion 9 is a pulley 12. A cable-13 passes from the drum 10 over the pulley 1 2 and back again to the drum. To follow out the cable more particularly, one end is secured at 14 and passes in the drawings to the right and over the pulley, thence through the cable-guide 8 to the drum 10, to which it is secured at 15. Another cable is shown in the drawings, though the two may be a single cable fastened at dif ferent points to the drum. The second cable is secured to the member 1 at 16 and passes directly to the drum 10, to which it is secured at 17.

18 illustrates braces for the stanchion 9. Thus it will be seen that the cable, considered as a single cable, has its opposite ends secured to the member 1 and its intermediate or working portion secured to the drum of the Windlass, or the cable may be considered as divided, with one having one end fastened to the member 1 and passing over the pulley 12 t0 the Windlass, the other fastened to the member '1 and leading directly to the windlass.

If the indlass be turned to wind up the cable attached at the point 15, it will draw the cable over the pulley l2 and pull out the female member 1 to the right, as shown in the drawings. 7 If the handle 11 be turned in the opposite direction, it will unwind the cable atached at 15 and wind up the cable attached at 17, which in the previous operation has been unwound. The'effect' of this second action will be to directly draw back the member 1.

I have thus combined in the simplest possible form an efficient mechanism for rapidly and certainly operating atelescoping pipe.

Having fully described my invention, what I claim is I 1. The combination of two telescoping pipesections, a cable, a power device carrying the cable and an opposed guide, the opposite ends of the cable crossing and attached to one of the pipe-sections at the limits of the reach of the cable.

2. The combination of telescoping pipe-sections, a standard attached to one section and bearing a Windlass, a standard attached to the other section and bearinga guide-pulley, a cable attached at one end to the movable pipe-section, passing to the Windlass, thence back to the guide-pulley, and thence back to the inner end of the movable section.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH RIESTER.
