UNITED STATES PATENT OEEICE- ABRAHAM E. PRICE, OF IVAYNESBOROUGH, PENNSYLVANIA, ASSIGNOR TO THE GEISER MANUFACTURING COMPANY, OF SAME PLACE.

DEFLECTOR-PIPE FOR PNEUMATIC- STRAW-STACKERS.

SPECIFICATION forming part of Letters Patent No. 557,020, dated March 24, 1896.

Application filed August 9, 1895. Serial No. 558,709. (No model.)

To all whom it may concern:

Be it known that I, ABRAHAM E. PRICE, a citizen of the United States, residing at Vtaynesborough, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Deflector-Pipes for Pneumatic Straw-Stackers; 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.

This invention relates to deflectors such as used on the discharge-pipes of pneumatic straw-stackers; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the deflector-pipe. Fig. 2 is a plan view of the same. Fig. 3 is an end view of the deflector-pipe. Fig. et is a section taken on the line o0 o; in Fig. 2.

A is a portion of the discharge-pipe of a pneumatic straw-stacker of any approved construction.

B is a deflector or deflector-pipe connected to the discharge-pipe and operating to direct the straw onto the stack. ,This deflector is formed of articulated conical segments b pivotally connected together at opposite sides by the pins h'.

C are eyes secured to the segments, and c is an endless llexible connection, such as a cord or chain, which passes through the said eyes and is provided with buttons c or is otherwise operatively connected to the eyes on the end segment. The lower part of the cord c is supported and kept taut by any approved devices for that purpose. In the drawings a sheave C is shown supported from the lower part of the discharge-pipe for thatpurpose. The deiiector is operated by pulling the cord c or by revolving the sheave C or other similar device which carries the cord. Thisdeflector is specially intended for use on strawstackers which have telescopic dischargepipes; but it may also be used on dischargepipes which are not telescopic. Vhen used on a telescopic discharge-pipe, the cord c is preferably supported and actuated as fully shown and described in my application for Letters Patent, Serial No. 546,512, filed April 2o, 1895.

Vhen the discharge-pipe A is telescopic, it cannot be revolved upon' its axis except by expensive and complicated mechanism, and as the deiiector-pipe moves in a vertical plane only when secured to the discharge-pipe the straw cannot be discharged sidewise at an angle when the discharge-pipe is not revoluble. In order to overcome this difficulty Vthe deflector-pipe is made revoluble upon the axis of the discharge-pipe, and the discharge-pipe is not revoluble. The deflector-pipe is revolubly connected to the discharge-pipe in any approved manner. An angle-shaped ring a is secured to the discharge-pipe and an angleshaped ring a is secured to the deflector-pipe. D are hook-shaped clips secured to the ring a and engaging with the flanges of the two said rings.

E are two guide-sheaves carried by abracket e, which is secured to the ring a. These sheaves are preferably arranged at the top of the discharge-pipe and a little to one side of its center.

F are two guide-sheaves carried by brackets f, which are secured to the ring a and are preferably arranged one upon each side of the deflector-pipe.

The operating-cord c passes over the sheaves E and F, as shown in the drawings.

G is a friction catch or brake of approved construction for preventing the deflector-pipe from revolving too freely. This catch preferably consists of a spring-pressed bolt g provided with a conical head and carried in a socket g on the ring a. lhe head of this bolt engages with a conical hole hin the face of the ring a and prevents the deiiector-pipe from revolving unless suficient force is used to retract the bolt. As many similar holes h as desired may be formed in the ring a.

The drawings show the deflector-pipe in its normal position on the discharge-pipe. The straw can be discharged at any desired angle in a vertical plane by pulling the cord c. When it is desired to discharge the straw sidewise at an angle, the deflector-pipe is rst bent around to its full extent and the IOO cord c is pulled upon with increased force. This causes the defleotor-pipe to revolve on the axis of the discharge-pipe against the resistance of the friction catch or brake G. Vhen the deeetor-pipe has been revolved to the desired position the cord c can be pulled in the reverse direction to operate the segments of the deleetor-pipe the saine as if they were movable in a vertical plane.

The deeetor-pipe can be revolved for nearly a full revolution and is revolved in the reverse direction to restore it to its original position. The sheaves E prevent the deieetor-pipe from being revolved for a full revolution, but as these sheaves are on top of the pipe and it is not often requisite to discharge the straw in an upward direction it :is practically of no consequence that the straw cannot be thrown upward Where the said sheaves are located.

l. The combination, With a non-revoluble discharge-pipe, of a revoluble and iiexible deflector at the upper end of the said pipe, and a single operating devicesuch as a cord running on guidesheaves-affording a means both for bending and revolving the said de- 'lector, substantially as set forth.

2. The combination, with adischarge-pipe, of a revoluble delector formed of articulated segments connected by pivots at their sides, and a single operating device, such as a ilexible connection, attached to the deflector between the said pivots and operating to bend and revolve it, substantially as set forth.

3. The combination, With adiseharge-pipe, and guide-sheaves supported at its upper end; of a revoluble deiiector formed of articulated segments, guide-sheaves carried by the said deiiector at its sides, and a flexible connection passing over the said guidesheaves and operating to bend and revolve the deiiector, substantially as set forth.

4. The combination, with a discharge-pipe, and a revoluble deector; of a spring-actuated bolt carried by one of the vsaid parts and engaging with conical holes formed in the other said part, said bolt operating as a friction-brake to prevent the deflector from revolving until sui'iieient force has been exerted to retract the bolt, substantially as set forth.

5. The combination, with a 11on-revoluble discharge-pipe, and an angle-shaped ring secured on its upper end portion; of a revoluble deiiectonpipe provided with an angleshaped ring bearing against the aforesaid ring, and means for supporting the defieetor and permitting it to revolve upon the aXis of the discharge-pipe, substantiallyas set forth.

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