PN EU IVIATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 601,356, dated March 29, 1898. Application led .Tuly l, 1897. Serial No. 643,173. (No model.)

To all whom it may concern.-

' States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Pneumatic Stacker, of which the following is a specification.

Our invention relates to improvements in pneumatic straw-stackers.

The objects of our invention are to produce, first, an improved telescoping portion for the stacker; second, improved means for chang- .ing the angular position of the stacker-tubes third, an improved hood construction; fourth, improved driving mechanism and means for automatically controlling the oscillation 4of the stacker-tube; iifth, an improved bearing for the fan-shaft; sixth, improved means for introducing the straw into the fan-casing, and, seventh, to provide various improvements in the details of the construction shown in Letters Patent No. 556,776, issued to A. A. Russell March 24, 1396. Y

The accompanying drawings illustrateour invention.

Figure 1 is a view in perspective of the entire stacker. Fig. 2 is a central vertical section thereof. Fig. 3 is a detail of the hoodoperating means. Fig. 4 is a detail of the fan-shaft bearing. Fig. 5 is a detail of the gear-reversing lever. Fig. 6 is a plan of the adjustable hood. Fig. 7 is an end view thereof. Fig. 8 is a perspective of the adjustable hood.

In the drawings, 6 indicates the fan-casing, in which is mounted a fan 7 of the usual form.

Leading from casing 6 is a discharge-conduit 8. Mounted at the upper end of conduit 8, and revoluble upon a vertical axis thereover, is a pipe 9, to the lower end of which is secured a gear 10, the said gear being mounted in any suitable bearings. near the lower end thereof, is a band 11,'provided with a pair of extending arms 12. Pivoted to the outer ends of arms 12 at 12" are the Vouter ends of a similar pair of arms 13, carried by a band 14, which is secured to a pipe 15. The upper end of pipe 9 and the cooperating end of pipe 15 are bent into arcs of a circle struck from the pivotal point 12", and pipe 15 telescopes over pipe 9. Secured to band 11 and extending upward therefrom are Secured to pipe 9,

two standards 16, between which is mounted a reel 17. Secured to the shaft of reel 17 is a worm-gear 18, which coperates'with a worm 19, provided with a hand-wheel 2O or other operating means. For the purpose of swinging pipe -15 around pivot 12 one end of a wire rope 21 is secured to reel 17, the other end being passed over and around a pulley 22, carried at the upper side of band 14, and then secured to the upper ends of standards 16. It has heretofore been thoughtnecessary to attach the outer end of the lifting cable or rope at some point near the outer end of the stacker-tube, and in such case a'derrick is erected over which the rope is drawn as shown in the patent mentioned above. In the present construction the derrick is removed and reel 17 is placed near the upper ends of the supporting-standards, so that the direction of pull from the reel to the pulley 22 is at all times 'substantially in line with the direction of movement, so that the stacker-tube may be easily lifted;

Mounted so as to telescope over the outer end of pipe 15 is a pipe 23. It is desirable that these two telescoping pipes be so arranged that when brought together theymay occupy a minimum amount of space. For thispurpose We secure to the upper side of band 14 one end of a bar 24, the arrangement being such that the inner end of pipe 23 may pass" Mounted at theouter andunder the bar. inner ends, respectively,of bar 24 are sprocket- Wheels 25 and '26, over whichis passed an endless chain 27, which is fastened at one point to theinner end of pipe 23. By this means pipe ,23 may pass under bar 24 and the inner end thereof may be brought back to the sprocket-wheel 26, thus providing for a considerable extension of the telescoping parts, at the same time allowing the parts to be so contracted as to occupy avery short space. Sprocket 26 is carried bya shaft 28, supported in suitable bearings in band 14. Secured to the outer end of shaft 28 is a hand-wheel 29,

.provided on its inner face with a series of teeth 30, which are adapted to coperate with a similar series of teeth 31, carried by a reel 32, which is loosely mounted on the shaft. Reel 32 is normally held in engagement with the hand-wheel 29 by means of a spring 33.

For the purpose of deliecting the straw downward as it issues from the outer end of pipe-section 65, hereinafter described,we provide a hood of the following construction: A portion of the bottom of the outer end of pipe 65 is cut away, and to the outer end of the pipe is secured a hollow spherical segment 34. Pivoted at 34" to segment 34, at the ends thereof, is a similar segment 35. Pivoted to segment 35 is a similar segment 36, and pivoted to segment 36 is a segment 37, any desired number of segments being introduced, so as to form an adjustable elbow of the desired angle. segment 37 have secured to it at its outer edge a segment 38, which forms a part thereof. The vari-ous pivoted segments are prevented from spreading too far apart by means of a short length of chain which passes from segment 34 to segment 38 and is secured at intermediate points to the intervening segments.' In order to maintain the hood in its open position, as shown in Fig. 1, a spring 39 is mounted at each side of the hood, one end of said spring being secured to pipe 65 and the other end secured to segment 37, the arrangement being such that the action of the spring is such as to resist the bringing together of the segments. For the purpose of adjusting the hood a cord 40 is secured at one end to the outer segment of the hood and at the other end is secured to reel 32. Reel 32 is of substantially the same diameter as sprocket 26 and is held normally `in engagement with the hand-wheel and shaft which' operate said sprocket. The arrangement is such, therefore, that when the pipe 23 is moved in either direction upon pipe 15 the cord 40 is l Wound upon or unwound from reel 32 at substantially the same rate, so that the length of the stacker-tube maybe adjusted without in any manner interfering with the adjustment of the hood.

When it is desired to adjust the hood, the operator separates reel 32 and hand-wheel 29 and then turns the said reel in the desired di-A rection. For the purpose of oscillating the stacker we provide the following mechanism: l Gear 10 is supported in suitable bearings carl ried by a framework which forms a part ofl or may be attached to a separator of any desired type. Supported in suitable bearings mesh with gear 10.

the clutch-teeth of the gears. tween gears 44 and'45 and intermeshing therewith is a bevel-gear 47, which is secured to one end of a shaft 48. Mounted upon shaft 48 and revoluble thereon is a gear 49, which It is preferable that the last may be engaged by a clutch 50, keyed to the shaft. Clutch 50 may be thrown out ofl engagement with gear 49 by means of a bellcrank lever 5l and rod 52. Gear 49 may be driven by any suitable means, such as worm 53 and pulley 54. Pivoted to the framework is a lever 55, arm 56 of which is adapted to engage clutch 46 and shift the same along shaft 41. Arm 57 of lever 55 projects over gear 10 in position to be engaged upon either side by one or the other of a pair of pins 58, which may be placed in any one of a series of holes 58, formed in gear l0, the arrangement being such that as the gear lO is rotated in either direction by the train of gears just described one of pins 5S will come into engagement with arm 57 of lever 55 and will swing the said lever upon its pivot and shift clutch 46,thus reversing the direction of movement of Worm 42 and gear l0. As gear lO is moved in the reverse direction the other pin 58 is brought into engagement with arm 57 and the direction of movement of the gear is again reversed. The angle of swing of gear l0 and the stacker-tubes carried thereby may be regulated by changing the positions of pins 58. In order tomaintain clutch 46 in engagement with either one of gears 44 and 45 and in order to throw the said clutch quickly out of engagement with one gear and into engagement with the other, arm 56 of lever 55 is provided with a forked end 59, which straddles the clutch and lies between a pair of collars which are sufficiently separated to allow the forked end 59 considerable longitudinal play. Mounted upon arm 57 of lever 55 and longitudinally movable in suitable bearings there* on is a catch 60, provided with a V-shape'd head 6l, adapted to engage a stationary pin 62. Catch 60 is yieldingly held in its normal position by means of a spring 63.

In operation when one of pins 58 comes into engagement with arm 57 of lever 55 the lever is swung upon its pivot, the forked end 59 of arm 56 thereof swinging freely between the collars of clutch 46. This movement of the lever forces the V-shaped head of catch 60 against pin 62 and thus forces the catch backward against the action of spring 63. As soon as head 61 passes the center of pin 62 spring 63 forces the said head forward, thus quickly bringing fork 59 into engagementl with one of the collars of clutch 46 and shifting the said clutch along the shaft out of engagement with one and into engagement with the other of gears 44 and 45.

It has heretofore been customary to place in the blast-fan casing a spreading cone, which operates to spread the straw after it has entered the casing. The great difiiculty has been to make the fan, the fan-casing, and the eye of the casing of such proportions that the straw would be properly removed from the casing with as small an expenditure of power as possible. made sufficiently large to easily admitall of the straw, then in order to create sufficient IOO If the eye of the casing is Y side of section 65. The opposite ends of cords draft the fan must be so large as to consume a large amount of power. In the present construction we place the spreading-cone 64 in the eye of the casing, but outside of the casing, the bottom of the cone being substantially inline with the top of the casing. By this meansthe eye of the casing is diminished in size; but the straw is separated and spread just at the point of entrance into the casing,

so that it easily enters into the eye and may be quickly disposed of by the fan. The cone may be supported upon the upper end of the fan-shaft, as shown in the drawings, or in any other desirable manner.

In'order to support the fan-shaft, we mount the lower end of said shaft within a socket or bearing 66, in the bottom of which is placed a disk or hardened bearing-plate 67. Between plate 67 and the end of the shaft is placed a series of balls 68. In order to adjust the bearing and to regulate the position of the fan within the casing, a set-screw 69 is placed to engage the lowerface of plate 67 and to support said plate at any desired point within the socket.

It is often desirable to be able to throw the threshed straw into a barn or mow. With the ordinary construction, in which the hood is mounted directly upon the outer end of the pipe 23, such disposition of the straw is practically impossible. W'e therefore mount upon the outer end of pipe 23 a short section of pipe 65, which may be rotated upon pipe 23, the section 65 being held in longitudinal position by means of bolts 70, which are secured to pipe`23 and passed through circumferentialslots 7l, formed through'section 65 near the inner end thereof. Secured to the outer end of section 65, in the'manner already described, is the adjustable hood, consisting of the Various segments 34 to 3S, inelusive.

Mounted near the outer end of pipe 23 are two pulleys 72 and 73, over which are passed cords 74 74, the outer ends of said cords being secured to a bolt 7 5, mounted on the under l. In a pneumatic stacker, the combination I with a pair of telescoping tubes, of a band secured to each tube, an arm carried by each band, the two arms being pivoted together, a standard carried by one of the bands, areel carried'bythe standard, means for operating the reel, a pulley carried by the other band,

land a cord secured at one end to the reel,

passed around the pulley, and secured at the other en'dto the standard, substantially as and for the purpose set forth.

2. In a pneumatic stacker, a hood for the outer end of the tube thereof, the said hood consisting of a series of hollow spherical segments each of said segments beingppivoted at each end to the adjacent `ends of the preceding segment only, and a spring, the ends of which are secured to the outer segments the arrangement being such that said spring will tend to spread or separate the segments.

3. In a pneumatic stacker, the combination with the fan-casing thereof, of `a spreadingcone mounted in the eye thereof, the said cone projecting above the easing.

4t.' In a pneumatic stacker, the combination l with the fan-casing thereof, of a spreadingcone l,mounted in the eye thereof, said cone projecting from the casing andthe bottom thereof being substantially in line with the top of the casing.
