Tothein nel is securedv oppositel a. formed with verticais`lo s tachably connect the har to the base of the- .formed which are projected through the door and .hear with their lower ends on the side pieces 'of the truck-frames, so that the floor may be adjusted vertically and maintained in properposition.v On the floor are secured plates 7, running lengthwise of the floor and extending over the extension 5, and between the inner edges of these plates is a dovetail channel -or groove 8, wherein is slidably arranged a coincidentally-shaped rack-bar 9, providedy with a perforated. lug 10 at one end to de spar. Mounted on the plates 7 at a suitable point are'oppositely-arranged standards 11 12, with bearings th rough them, wherein is journaled a shaft 13, having mounted thereon between the standards a pinion 14, which engages the teeth' of the rack 9 and serves to move the rack in either direction. The shaft, with the pinion, is operated by a crank-handle 15, which may be connected to either end of the shaft, or a crank maybe used at both ends, if desired. To the front end of the floor or platform, is hinged orjointed a plate 16, adapted to turn down into horizontal position, as seen Fiffs. 2 and 1i int-o alineinent with the face i D ci' the platform, er te he turned up and inciined back, as seen in Fig. 1 of the drawings,

in which latter position it constitutes a sup-- port for the drivers seat or seats 17, which consist of bottom, pieces provided with arms of any suitable style. In the back face of the plate 7 is formed a groove or channel 18 in alineinf' t wif, the groove 8, so that the rack-bar ,ty in. its movements extendinto the groove 18 and he held in proper relation 'for its entire length. Midway of the length of the floor is made an opening 19, bounded by the severed .ends of the floor-plates 7 and by side plates 20, and in the opening thus formed is posited a table 21, formed with a central opening 22, through which a turningplug projects andextends, vertically through the base of the spar when that element is brought into alinement therewith, as hereinafter stated. The table 21'is formed with c entral laterally-extending trunnions 23, journaled in bearings in the side plates 20, and centrally and 4len,f.,1fthwise of the table is a groove, groove in or between the floor-'plates and through which the rack-bar 9 travels. It will heseen that the table has a limted'tilting, movement, sothat the spar when standingl thereon may be inclined yin either' direction, as shown in Fig. 2 0f the drawings by the dotted lines.,` `.'llogn'event thev table' from be#- ingstilted except as `may .bedesired or ireasshown, which alines'with the quired, catches24are provided, which engage under the floor and hold the table in alinement with the face of the platform. To the under side of the table is secured a plate 25,

constituting a housing wherein is journaled a short vertical shaft 26, on which is iixedly mounted agear-wheel 27. The portion of the shaft 26 which extends above the wheel 27 is made angular, as shown, and has litt-ed to slide thereon a turning-sleeve 28, also having an angular-.exterior conformation adapted to (it in an angular opening in the lower end of the revolublesection of the spar and turn it on its axis. The sleeve 28 and the wheel 27, with its shaft, and the turning-sleeve 28 are turned by means of a worm 29 on a shaft 30, journaled in hangers 31, rigidly secured to the under side of the table, as shown, the shaft being provided with .a crank-handle to operate it. In order that the ,turning-sleeve 28 may be withdrawn from engagement with the spar or be depressed to prevent interruption of the progressof the rack-bar 9, I

provide levers to move the sleeve. These levers consist of a bar 32, pivotally mounted under the platform and preferablyvarranged in transverse direction thereto., 'The inner end of this bar 32 has loose connection with the second lever`33,pivotally supported from lthe platform and having its inner end slidingiy disposed through a loop 34 on the end of a lever 35, fulcrumed to the under side of the table 21. The inner end of the lever 35 is forked, as at 36, the forks engaging in an annular groeve 37 ina collar on the turning-sleeve 28 and depressing it against the force of the spring 28x. It will be perceived that when the outer end of the bar or lever 32 is moved in upward direction vvits inner arm will move the lever 33to actuate lever 35 to draw the turning-sleeve 28 down either from engagement with the spar or so that it will not impede or stop the movement of the rackbar 9.

36 designates a plate hinged to the base of the relatively stationary section ofthe spar and formed with ,connecting-lugs 37' to detachably engage with the lug '10 on the end of the rack-bar 9. The plate 36 has an opening 38,through which the .tu ming-sleeve 28V passes -into the opening in-thebottom of thespar,

andjis also formed' with a longitudinal rib 39 on vits under face to slidingl'y engage in .the groove 8 of theplatform- "Ihe' base of the lowermost section 40 of the spar is formed with a base-piece 4&1- coincident in shape to the plate 36'and -iS joint ito'said plate.'l The.) .wermost section of the extensible'sp'ar is designated by the referetico-numeral 420, and consists of a cylindrical. shell of the required length and diam' eterto adaptit to the purposesl intended, and

because of itshiuged connection to the-base'- plateit may bev d ispos'edgin linclined posij tion, as seen in' the drawings, or itfcan be,

through the agency ofthe lrack-har, made to assume a vertical positiongas seen in Fig` 2 connected by the hinged IIO of the drawings. This section 40 is relatively stationary tothe other sections of' the spar, being neither rotatable nor extensible.-

Adjacent to the. upper end of the spar-section 40 is secured a collar 41, having laterallyprojecting and alining lugs or studs 42, on which are pivotally disposed strut-rods 43 44.

At the front end of the platform are secured op-l sitely-placed benches .45, provided with suitable bearings, whereinis pivotally supported a plate 46, formed with sleeves at each side, wherein lare slidingly disposed the strut-rods 43 44. across-bar 47 is rigidly secured to-the strutrods, and secured to the cross-barista rackbar 48, which extends frontward under the plate-46 and is engaged by a pinion-*49 on a shaft 50, mounted inbearings fixed to the under side of the plate. A crank-handle 51 is provided to turn the .shaft 50. Ratchetwheels 52 53 are mounted on the shaft, which are engaged by suitable pawls 54 to prevent back movement of the strut-rods and to hold them ,in such position as they may be moved longitudinally. c i

It will be perceived that when the base of the spar is drawn toward the front end of the platform the movement operates to elevate it in the direction of verticality, because of the pivotal connection ofthe stru t-rods,which serve as a point on which the sparswings. When the spar has been-raised to vertical position, it is held in such position by the strut-rods; but if it be necessary to tilt the spar to the left, as shown in dotted lines in Fig. 2 of the drawings, the strutrods-are drawn toward 'the front end of the platform, in which movement the plate at the base of the spar tilts on its hinge connection; lout shouldit be required totilt the spar to the right, as shown in dottedy lines in Fig. 2 ofv the-drawings, then the catches or locks of the table are released, the table being then free to be tilted on its bearings. Then by extending the stru t-rods the spar will be correspondingly tilted.

ATo the plate 46 are pivotally secured hooks 55, which engage in eyes or staples 56 in the hingedseat plate or piece and hold itin position when occupied as a seat bythe driver.

Erected on the platform is a frame constituting a support on which the spar Arests and is held when posited in inclined position, as,

shown in the drawings in Figs. l and v3. This supporting frame comprises, oppositelyplaced standards 57.58`of such heightas may be required/ and having their upper ends united by a strong. cross-piece 59, on which are mounted cushiontsprings a, which carry a bolster-piece b, formed with a curved Vre- -cess 60, wherein the spar rests. l On the upper end of the spar-section 40 is loosely and revolublyfsecured a collar 6l, which is formed with diametrically opposite recesses 62 to take in bearing-lugsS, projecting from the second section of the spar. To the lugs 42 of the collarl arepivotallyf At a point in advance ofthe plate 46 f hung arms or linksA 64, to which are secured the upper ends of 4guy-ropes 65, which may be secured at their lower portions to staples 66 at lthe sidespof the platform, and' thus stay the spar against lateral displacement,

lIn the spar-section .40 isplaced the secondA spar-section 67, which extends to the bottom of the section 40 and Iis revoluble but not ex-jA In thebottom of the: section 67 is an angular opening 68, in whichf tensible in its position.

thel turningvplug or sleeve 28 engages and. v

serves toturn the section 67 on its axis. Onthe Spar-,section 40 are formed collarsK y 8o 69 70, rigid therewith, the collar 70 being provided with radial notches'Zl, wherein a lock-1 horizontally, forming endvba'rs 75, formedl with bearings posited-in alinement withl the bearings in the sleeve 73, and the frame end bars Vare carried inward and upward, as at 76, and have their ends fixed to the sleeve.

At the angle of each of the end bars 75 and brace-bars l7 6 is formed a bearing 77, wherein is journaled the winding-shaftl78. Between each end lbar and the bearing in the sleeve is mounted a shaft 79, whereon isa windingdrum SO, at the inner end of which is secured a toothed wheel 8l, which is engaged by a pinion 82 on the shaft 78. This shaft'78 also has bearing in` bearing-ears 83 84, secured to the sleeve 7 3,-substantiallyas seen in the drawings. On the sleeve 73 is hung the lockinglug 72, which engages by gravityin any one of the notches 7l in the cbllar 70 to hold the' sleeve locked against rotation on the lowermost sect-ion of the spar, as heretofore mentioned.. 'The shaft 78 isy provided with a crankhandle 85, by which it is rotated Ratchet- .I OO

over which lifting cords or cables 90 are arf 'Y ranged. The cords 90 have their lower ends secured to the drums 8O and thenceare car- -vried ,up-over the pulleys 89, thence through apertures in the spar-section`67, and from thenceare carried down'and have their ends inside the spar-sectionA secured to the lower end of the `rst extensible spar-section 91, as

seen in Fig. 16 of the drawings. The sp'- section 91'" is thus-lifted vertically within the :revoluble section 67. The section 91 is made 'To the end Virinded to be p with' oppositely-arranged longitudinal-channels or grooves 92 93 to afford cord-space for the lifting-cords 90 to'l move in. About the upper end of the' section` 67 is secured a collar 94, formed with diametrically disposed perforated lugs 95. In the extensible section 91 is slidingly posited the second extensible spar-section i, having opposite channels to -aecommodate the'lifting-cords' by which it is extended. To the lugs 95 are fastened the ends oflifting-co'rds 97, which are carried np over grooved pulleys 98, mounted. at opposite sides of the section 91, thence through perforations in the section and carried down on the inner side thereof, and have their ends suit- .blysecured tothe base of the spar-section 96.

Within the spar-section 96 is slidingly and extensibly positedithe spar-section 99, having a'lifting-cord 100, attached to a collar 101 on the spar-section 96 and from thence carried rover a pu'lleyl02 adjacent the top of the spar-section, as shown in the drawings.

Within the spar-section last named is extensibly arranged the terminal spar-section 103, made U-shaped in cross-section, and in the groove orchannei 104 thus formed is pivotally supported an angular section 105, adapted to lie within thesaid channel andto swing pntward on its pivot 106, as shown in the drawings, .for the purpose of reaching laterally any object.

Within the hinged spar-section is slidingly disposed an ,extensible rod 107, which is in- 'iected longitudinally of the spar-section L, 'e on tension is accomplished by means of r or like cable 10E, secured to the outer end or said rod and carried over a sheave 109 on the end of the section, and from thence extends to a winding drum or reel 110, jonrnaled in a casing 111, mounted on -the platform.

of the extensible rod 107' is fixed a cord 112, which extends down and is secured to a windla-ss 113, whereby when the spar is extended toits limit or to the point desired it may be collapsed or telescoped by drawing downward on the cord 112. A 1 It will now be perceived that the various sections of the spar are simultaneously extended,with the exception of the terminal bar 107, and that they are collapsed in thereversed'order of their extension. To the topmost spar is connected one end of a stay rope or cable 113% the other end of which is fastened to the hinged section to stay it' and prevent it being carried out farther than intended.

' A cleat 114 is xed tol the sleeve on the base-section of the spar, to which the rope of the basket may be secured in a Well-known manner, and additional cleats may be provided, as 115, towhich the ropes of the top sections of the spar may be secured as desired. To the outer end of the extensible.

bar'posited in the hinged section is xed a grooved pulley 116, over which a cord' or cable 117 is arranged, to the one end of which is secured a basket or cage 118, the hand portion of the line or cord extending down to some convenient point for manipulation.

The respective ,functions of .the several parts a'nd their coacting arrangement and aggroupment have been vparticularly stated in the premises of the description, and the usesl and operation may now be stated generally,

' as follows: The apparatus is shown in static position in Fig. 1 of the drawings, ready to be drawn wheresoever required. When the location is reached Where its uses are required, the team fis detached and the seat-plate is turneddown into alinement with the door of the body or platform. The rack-bar connected to the base-plate of the spar is then actuated through vthe medium of the `pinion to draw the lower end of the spar toward the middle of the platform and onto the table into vertical position. During this movement the strut-rod mechanism is operated to assist in the elevation of the spar. When the base of the spar is drawn centrally onto the table and the opening in its base registers with the turning-sleeve, that element is moved upward by the. force of the spring into engagement with' the spar, which is then in vertical position. The guy-ropes may then be secured to keep the spar fromtilting sidewise and other braces applied to the trucks, as mentioned. The winding-drums on the sleeve at the base of the spar are then turned, which results in the extension of the telescopic sections to their limit, ii desired; and then the hinged section falls out of the channel in is' seated and carries with it the basket to present it where required. Should the distance at .which the basket is to be presented be greater than 'the now inclined hinged section reaches, the rod it contains is extended to supply the deficiency. If it is necessary to swing the basket around on the plane of its height, then the turning mechanism under -the platform is operated and accomplishesthe purpose. If it becomes necessary to tilt the spar in either direction in the longitudinal line of the platform, then the table is unlocked, which permits it to havealimited ro-` tary movement on its trunions, and then the strut-rods are shortened or lengthened, as the direction may require. When the work has been accomplished and the basket has descended and delivered its burdens, the winding mechanism on the spar is released and by turning in reverse of the movement which extended the spar the sections descend by gravity into original position. The turning plug or sleeve maythen be depressed to disengage it from the spar, and then the rack is operated. to move the lbase of the sp:l r to the point from which it was moved, and it again assumes-the inclined position.

It may be stated that when it is required to tilt the spar with the table the rack-har` is disconnected for the time being.
