A fan or blo-wer 2O is mounted at ythe forward end of t-he frame 10. The intake or suction pipe 2l of the blower-20 extends vertically upwardly, in the manner clearly shownin Fig. land has a plurality of flex: ible conduits or. hoseconnected into it at its upper. end. lThe hose22 areadapted to be operated ormanipulatedwby attendants in the manner hereinafter described. These hose 22may be. rubber or iexible metallic hose and may be of various lengths to suittheparticular circumstances under which the machine is to be operated. In the -particular construction shown in `the drawings two hose connect into the front of the suction pipe. and one hose connects into each' side. of the 'suction'pipe The hose 22 which j connect-into they sides' of the suction pipe may be'supported by a horizontal cross arm l24.

The suction pipe 21 isadjustable or extensiblefbeing formed of two sections 25 and 25EL one slidable within the other. lhe section 25a is the lowermosti and is connected directly to the blower 20, while the section 25 is uppermost and is adapted to slidably fit within the lower section 25a. The fitting of the upper section into the lower one prevents cotton being4 caught at the' joint between the two sections asit` passes downwardly to .the fan. yThe `joint between .the two sections 25 Vand 25a is sealed by ai band 27, preferably leather, or. the like, which is arranged around it in the manner shown in'Fig. 4. A split clamping ring 28 is arranged around the band 27 andA is formed with flanges 23 which carry bolts 29. The bolts 29 may be tightened so thaty the two sections 25 and 25.a are solidly held or clamped against relative movement or they may be tightened so thaty the two sections may-'be moved or adjusted by hand. In practice it may be found desirable to ,adjust the suctionpipe to the. proper height for the particular circumstancesunder which the machine is to operate and4 thenl solidly and securely clamp it in that position.` It will be understood howthe suctionv pipe' maybe adjusted to a heightwhere lthe cotton willl be drawn through the rhose 22. in the most effective manner and with the leastamount vof resistance, vThe details of Vthe connection betweeny the sections 25 and 25a,L are clearly shown in Figs. 3 and 4 ofthe drawings. It will be noted in the drawings that the'upper part of the bland 27-is considerably thicker than the lower part thus permitting of the splity ringbemgt of `unfermdiameter and yet causing the section 25 andthe section 25a to be gripped uniformly when the clamping bolts 29 are tightened.- 'Ihis particular portion of the machine is believed to be particularly noteworthy in that it provides a novel, simple means for adjusting the length of the suction pipe and thereby adjusting the hose to the most desirable and advantageous height. The particular construction at this part of the machine is noteworthy in that it provides a conveniently adjustable structure which is simple and inexpensive to manufacture and which does not interfere with the operation ofthe machine in any way. c

f, The blower 20 comprises generally a suitable casing into which extends a shaft 40.

A plurality of paddles 39 yare carried within the casing on arms 38 which extend from a hub 88a mounted on the shaft40. InV the preferredl form of construction a disk `38b is carried on the shaft 40 in the manner shown in Fig. 6 to support or brace the'paddles 39. In they particular form of construction herein set forth the casing comprises a central vmember 42 `which extends around ythe paddles 39 and is secured or carried between two plates 44. The member 42 and plates 44 may be advantageously connected by angle irons 43 in the manner clearly shown in Fig. 6. A bracketV or casting 45 is bolted to one of the plates 44 and is formed with a bearing 45a in which is carried the shaft 405y and is formed withV a foot 48 adapted to be. bolted to the frame lO. A bracket or casting 46 isbolted to the other plate 44 and is formed with a neck part 47 which carries the section 25a of the suction pipe and connects the section 25L with the interior of the fan casing, `and is formed with a foot V49 adapted to be bolted to` theframe l0. The vfan is driven'from shaft 16 by a belt 50 carried on pulleys 51 and 52 mounted on shafts 16 and f4() respec tively. The shaft 16 being a constantly operating member the fan is operated at all times even when 'the machine is `not being moved. It will be readily understood how the particular arrangement and construc- Y tion just set forth is simple and inexpensive and how it permits of the fan being easily and quickly taken apart for cleaning7 etc.

-The discharge pipe 54 of the fan is-connected with a V-shaped,:or forked, distributing pipe 56 by a vflexible Apipe 55. The distributing pipe is mounted on the upwardly and rearwardly extending `member 141'01C thehandle 14 to be near the cross bar 14 and to have one of 'its sideportions 57 on each side of the member 14a, as clearly shown in the drawings.l "The outer end portion of each side portion preferably turns ,downf wardlyso that. the cotton ywill be discharged dpwnwardly. A valve is arranged Vin the distributing ',ppeatthe junction 'of the 'eide portions 57. The valve is carried on a stem 6() which has an operating lever 61 mounted on it at the exterior of the pipe. From inspection of the drawings, particularly of Fig. 5 of the drawings, it will be understood how the valve can be operated to close off either one of the side portions and cause all of the cotton to discharge through the other side portion, and how it can be operated to allow both of the side portions to be open so that the cotton will discharge through both of them. When the valve is thrown to either side, that is so as to close either one of the side portions, it will remain in that posit-ion until positively operated or moved by the lever 61.

Two bags are carried by the handle 14 to receive the cotton from the distributing pipe 56. Each bag is carried by hooks 66, mounted on the member 14 and cross arm 14h, so that its top is open and so the one of the side portions 57 extends slightly into it. The bags being carried by the hooks can be easily arranged in place and removed from the machine.

ln the preferred form of construction a guard or shield 8O is arranged around the machine so that it can be passed between the rows of cotton plants without injuring or catching them.

In the operation of machine the engine 16 is constantly operated causing the fan to be constantly operated and permitting of the machine being moved whenever desired. The outer end of each hose is placed by an attendant at or near ripe bolls of cotton so that the cotton is drawn into the hose by the sucking action of the fan. It will be understood how the cotton from the several hose enters the suction pipe 21, passes through the fan, passes through the discharge pipe 54 and the conduct 55, and finally through the distributing pipe 56 from whence it is discharged into the bags 65. Anwoperator manipulates the clutch mechanisms to move the machine as the cotton is gathered, and removes the bags from the hooks as they are filled and replaces them by the empty ones. It is obvious how the operator can manipulate the valve 58 so that one bag is being lled while a full bag is being removed and an empty one put in its place. This manner of operation is continuous and makes for quick efficient picking of cotton. When a machine is constructed with four hose as shown in the drawings two rows of cotton can be picked at a time. Two attendants can pass between the rows of cotton between which the machine is moved and can each pick ythe cotton on the inner side of one of the rows. Two other attendants can pass along the outer side of the rows and can each pick the cotton on the outer side of one of the rows.

We claim- In a cotton picking machine of the character described, supporting wheels, power means supported by the wheels, a releasable driving connection between the power means and supporting wheels, a blo-wer, a driving connection between the power means and the blower, a hose in connection with the intake of the blower, a handle in connection with t-he parts supported by the wheels by which the machine may be guided, control means for the iirst mentioned driving connection and extending to the handle so that said driving connection can be controlled by a person operating the handle, a conduit in connection with the discharge of the blower and extending to thehandle, and a bag detachably carried at the handle to receive cotton from said conduit. y

Tn witness that we claim the foregoing we have hereunto subscribed our names this 30th day of September, 1920.
