To all "w/wmc't may concern.

Be it known that 1, Sr. ELMO BATEMAN, a citizen of the United States, residing at Los Angeles, in the county of Los-Angeles and State, ofv California, have invented certain. new and useful Improvements in Fumigating Apparatus, of which the followingTis aspecification.

. This invention relates to means for raising andlowering canopies, tents and the like, and the primary object of the in vention is to provide an improved means for quickly and easily placing and removing canopies over citrus trees and the like, during the treating thereofi'by fumigating gas for scale and other pests that damage the trees. 1

Another object of the invention is'to provide an improved apparatus embodying a. pair. of wheel trucks. arranged to support an overhead frame, the frame having an improved means. associated therewith for permitting a canopy or the like to be quickly raised or lowered overa tree to be treated. A further object of the invention ,is. to providean improved apparatus for aiding in fumigating of fruit trees-and the like which is of such a construction that the samecan be readily moved between the rows of trees in anorchard and when in one posi-. tioncan effectively reach four different trees, so that the canopy can be readily placed over or removed from the same with out necessitating the repositioning of the apparatus for each tree; I A further object of. the invention is to provide an improved apparatus for use in treating of trees in which the frame is ad justable within certain limits and so arranged that trees spaced various distances. I

apart can be effectively reached by the apparatus without necessitating the reposi tioning thereof, the adjustable frame" also permitting the effective treating of trees of various heights and circumferences.

A further object of. the invention is to provide an improved means for detachably associating the hoisting cables of the apparatus with the canopy so as to permit the hoisting cables to be readily attached to or detached from the canopy.

A further object of the invention is to provide an improved canopy which has associated therewith in a novel manner a pair of spaced canopy. ropes, slida-bly Specification of Letters Patentf Patented Au 22,. 1922. 1920. Seria1-No. 399,649.

Referring'* to the drawings, in? detail,

wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indi cates the improved apparatus and B one of the improved enclosing canopies.

The improved apparatus A includes a main truck C and a forward truck I), a supporting bridging frame E carried by the trucks and the lifting cables F.

.The main truck 0 includes a platform or bed plate 5 the opposite ends of which carry suitable supporting axles 6 on which are rotatably mounted the forward and rear wheels 7, which may be provided with suitable tires 8, which may be of the pneumatic variety if so desired.

The central portion of the truck is provided with an upstanding bearing 9, the upper surface of which is semi-spherically shaped for a purpose which will be hereinafter more fully described. The bearing 9 is adapted to receive the upstanding vertical hollow post 10 the lower end of which is shaped to conform to the configuration of the bearing, and it can be seen that the post is free to swing in said bearing. The upper end of the post 10 is provided with a collar 11, which supports a plurality of right angularly positioned radially extending eyes 12 which have pivotally connected thereto the depending guy rods 13. The guy rods 13 have interposed therein suitable turn buckles 14 whereby their lengths may be adjusted. Two of the guy rods 13 are arranged at the longitudinal center of the truck C while the other two guy rods 13 are arranged at the transverse center of the truck. The two rods 13 which are arranged at the longitudinal center of the truck are connected by a flexible sprocket chain 14, while the other two rods are connected by a flexible sprocket chain 15. Suitable guide wheels 16 are carried by the sides of the truck for receiving the sprocket chains and it can be seen that the sprocket chains pass entirely under. the supporting platform 5. The platform 5 supports on its lower surface a longitudinally extending shaftl?- which has keyed or otherwise secured thereto a sprocket wheel 18 which is adapted to engage the sprocket chain 15. The shaft 1'? is provided with a suitable crank wheel 19 whereby the same can be rotated. it can be seen that by rotating the crank wheel 19 the sprocket chain 15 will be moved transversely of the truck, and thereby swing the post 10 at an angle to the vertical longitudinal center of the truck. The lower surface of the platform 5 also rotatably supports a transversely extending shaft 21, the outer end of which is provided with a crank wheel 22 for permitting the rotation thereof. The inner end of the shaft 21 is provided with a sprocket wheel 23 which engages the longitudinally extending chain i l andjit can be seen that by turning the crank wheel pendicular position. This is easily accom-' plished by the manipulation of the crank wheels 19 and 22. Suitable releasable locks 24; and 25 are provided for engaging the sprocket wheels 18 and 23 respectively and these releasable locks each include a pivoted lever 26, the free end of which is adapted to engage in the teeth of the sprocket wheels. The opposite end of the pivoted lever is connected to a link 28 which is pivotally connected to the inner end of an operating foot pedal 29. l/Vhenit is de-' sired to operate the shafts for adjustingthe position of the post 10, it is merely necessary to depress the foot pedals 29 and rotate the cranks 19 and 22.

The supporting post 10 slidably receives a standard 30 which is adapted to be attached to the overhead frame E which will befhereinafter more fully described. The

standard 30 is adapted to be held in any adjusted position by means of a removable pin 31,. which is adapted to be placed in any one of a plurality of apertures 32 formed therein. By adjusting the standard 80 the height of the overhead frame E may be regulated in relation to the truck and to a tree which is to be treated.

The forward truck .1) embodies an axle 32 which is rotatably mounted in a suitable bearing sleeve and this bearing sleeve is provided with a pair of upstanding spaced ears 34 between which is positioned the lower flattened end 35 of a sup porting post 86. The opposite ends of the axle 32 support wheels 37' which may be provided with tires 38 of the pneumatic type. A draft tongue 39 isprovided for the forward truck so as to permit drawing of the apparatus to the trees which are to be treated and this draft tongue includes downwardly extending right angularly disposed feet 40 which are adapted to dig into the ground to prevent accidental movement of the truck D when the frame E is posi tioned for lifting or lowering one of the canopies B over a tree to be treated. The tongue 39 also supports an angular extending arm ll which extends in an opposite direction to the feet 40 and this arm is provided with a substantially circular collar 42 which is adapted to rotatably engage the bearing 33. When the truck Dhas been placed in an adjusted position the tongue 39 is swung downwardly as clearly shown in Figure 11 of the drawings which will throw the feet 40 into engagement with -the like.

suitable guy rods 52Wl'll0l1 extend .longitu- V dinally of the frame and are connectedmesses the ground andraise thewheels 37 olf of the ground. The forwardendof'the tongue 39 engages theupper surface, of the ground asv Will the feet 40 and thus'it can be seen that a relatively large bearing surface, is providedv for the forward truck so as to hold the same against movement. The

lowerfiattened end 35 of the supporting post 36'is pivotally connected to-the ears 34: by av pivot pin 43 and thus it can be seen that the supporting post 36 is' also free toswingin relation to. the forward truck D. Thisv permits the standard 36 to swing in relation :tothe post 10. The post 36 is of hollow formation and slidably receives a standard la-Which is held in its adjusted position by a suitable removable pin 4C5 which is extended through any oneof a plurality of openings 46 formed therein.

The upper-bridging supporting frame E I includes a palr'of spacedlongltudinally extending side bars 47 and end bars 4-8 and 49. The end bar 48 has arranged adjacent theretoa pair of spaced parallel bars and 51 Which extend transversely across the frame. The bars 47, l8, 49:, 50 and 51 may benformed. of any preferred material but the same is preferably formed of piping or The frame, E is also'braced by thereto at the central portion thereof by means of relatively short, vertically extendingrods 53. The upper ends of the standards 30 and 44: carry transversely extending semi-cylindrical rods 5% which are adapted to engage the transversely extend.

in end bars or cross rods of the frame.

The terminals of the. semi-cylindrical rods swung on the upper frame When the trees;

are positioned at various. distances from each other and it can be seen by swinging back the clips 56 the upper frame can be I entirely detached from the standards when 47, and these feet are held in place by. suitdesired. The upper frame has also arranged thereon transversely extending hollow pipes. 59, one of WlllCllr is arranged relatively nearer the end ofthe frame than the other. These hollow rods 59 carry suitable depending feet 60, which areadapted to embrace the longitudinally extendingside bars able retaining bolts 61.. Each of the hollow rods. 59 has slidably mounted therein the oppositely extendingsupporting arms 62,

-73 of the hoisting cables '72.

the outer ends of which arebent angularlya as at 63. [The upper terminals of the angular ends of the rods v62 support guide.

pulleys see around which are adaptedtobe trained the hoisting cables-forjthe canopy The inner ends of the sli'dingarms. 62

.carry upstanding plates 65 whichprotrude.

throughgrooves 66 formed in the hollow rods 59. These plates 65. formguides for; Y

the arms and prevent rotary movement thereof n the'hollow. rods. are also braced by 'fdiagonally extending guy rods 66-Wlil0h have. the terminals connected respectively to, theupperen'ds of the angular terminals 63 "of the arms and the, plates 65.

of, base plates 66f, whichhave outwardly extending arms 6?, which support rollers 68. hese rollers'68 also form guides for the hoisting apparatus. The end barsy l8 and suitable guide pulleys 70 which also are adapted to re'ceivethe hoisting. apparatus;

The hoisting. apparatus F includes a longitudinally extending cable 71, the terminals of Which hang over the sides ofthey frame and formthe pulling ropes. This long1tudinally extending rope is trainedaround the pulleys 70. Each'of the-pulleys 6.4 have trained therearoundv the hoisting cables 72 andthe inner. ends. of the cables 72 are trained around the guide; pulleys68 and;

are connected to the longitudinally extendingrope 71. The'lower terminals of the hoisting cable 72 carryfsuitahle snap hooks or locks 73, which are adapted to engage the canopy B. Thusit can be seen that When either end of the pulling cable'is'artuated the hoisting .cables 72 Will be raised.

The improved canopy QB ispreferably formed of canvas or, the like and is" substantially rectangular shaped with the cornersthereof cut diagonally as clearlyshown 3 in Figure 12 of the, drawings. -This forma tion allows the canopy to assume a substantially circular shape when in'kuseg, as shown in Figure '1 of the dratvings. Arranged longitudinally of the canopy, B is 'a pair of spacedcanopyi ropes 74E whichare .slidably mounted in a pair of. rows of guide eyes 75 secured to the outer surface of the The arms 62 The hollow rods 59 also have securedthereto at thecentral portionthere- LQ-havealso securedintermediate their ends canopy. The outer Tends of'these eyes 75 i are loosely secured tothe canopy by means of'ropes 76. Theterminals of the canopy. ropes 74; are provided with rings 77 Which are adapted to be engaged by the snap hooks H The rings 77 also prevent pulling of the canopy rope.

through the eyes 75. In Figure; 13 1s illus trated alayout of an orchard and it"can be seen that the trees are arranged'in spaced parallel rows which are substantially equidistant apart. The trees are generally planted 20, 22 or 24: feet apart; and the ims eff of the first tree.

proved apparatus is so constructed as to readily treat trees positioned these distances apart.

The improved apparatus A is moved be tween a pair of spaced rows of trees in the orchard and the main truck C is stopped at a point approximately equi-distant from four of the trees. The front truck 3) is then pulled around untilthe frame E is positioned over the first tree. This action is permitted owing to the fact that the standard SlO is ro tatably mounted in the post 10. When the front truck D reaches toe desired position the tongue 39 is swung downwardly until the feet 40 are forced into theground, which holds the front truck against movement. Prior to this, one of the canopies B is se-' cured to the hoisting cables 72 by means of the snap hooks 73, which engage in the rings 77. The pulling cables 71 are then operated which elevates the canopy above the trucks. When the forward truck D has been positioned in correct relation to a tree to be treated, the cables 71 are T leased which permits the canopy to be lowered over the tree. When the canopy has reached its correct position the snap hooks 7 3 are released from the rings 77. Another canopy is then at tached to the snap hooks and the forward truck D is then swung around so as to move the frame E over the adjacent tree in the outside row. This canopy is then lowered over the second tree, after which the apparatus is then moved. between the next four trees indicated by the cross mars and the main truck C is positioned equi-distant from these trees. The forward truck D is then moved so as to position the frame E over the tree of these four after which the truck is moved so as to position the frameover the second tree of these four in the first row. This operation is repeated until all of the trees of the first row are covered with the canopy. As toe time requiredto fumigate tree is thirty to fifty minutes, by the time the apparatus has reached the last tree in the first row the canopy from the first tree in the first row can be removed. The apparatus is then brought back to the starting point and the truck D is then moved so as to posi- C tion the frame E over the first tlee; The

snap hooks 73 are then placed in eng gement with the rings 77 and the canopy is lifted The truck D is then swung around over to the first tree in the second row which will. position the frame over the same. The canopy is then lowered over the first tree in the second row sitter which the forward. truck is swung around the second tree in the first row so as to permit the positioning of the frame thereover and the canopy is lifted of the same. After the canopy is lifted the truclr D is swung in front of the second tree in the second row and the canopy is then lowered trees in the orchard have been treated.-

If the trucks are positioned on a hillside the posts can be readily held and moved to a perpendicular position by operating the cranks 19 and 22 as herebefore described. Tf a relatively high tree is to be treated the standards 30 and 4A can be readily raised. For trees of a relatively large circumference, it is merely necessary to move the arms 62 outwardly until the desired adjustment has been reached. Where trees are spaced a relatively large distance from each other it is necessary to raise the frame E by moving the standards 30 and a4; on the posts 10 and 36, and the standards are then swung outwardly on the clips 56. It also can be seen the connection of the canopy ropes 74L it can be seen that when the hoisting cables 72 are raised the lower ends of the canopy will be elevated first. After they have been elevated a certain distance the other parts of the canopy will be raised. j i

From the foregoing description it can be seen that an improved canopy or apparatus been provided for use in fumigating fruit trees and the like. f

Changes in details may be made without departing from the spirit or scope of the in rention; but,
