The fixed support, which may be constructed in any desired manner, preferably consists of a 75,

s ngle bar of metal bent at opposite sides 01 the center, as shown in Fig. l, to form the transverse portion and the parallel sides, the transvverse portion 5 being localed at the upper faceo'f the sides ei. and formmgstops for llnuting the outward movement of the exteigsible section a. The extensible section 6, which is substantially rectangular. preferably consists of a single bar of metal bentat opposite sides of the center in the same manne as. the iiii'ed 5 support and provided at the inner'ends of its sides 8 with pro i etin, lugs 9. The sides 8 slide on the lower or front faces of the sides 4, and the flanges extend around the outer edges of the sides 4 and are arranged on the 9 upper or rear faces thereof, whereby the e."

tensihle section 6 is slidahly eoimeetedwitlr 'lhe extensible section 15 placed in a verticalposition.' When the truelg is arranged in a vertical position and 1s subjected to..,the weight'ot' a load, ltwilla'eniain firmly in such position, and as the'wheels 10 l clear or the ground of the truck will 'he'l'if r Fig. 6 is an enlarged 55 or other supporting-surface a rigid base is aflorded, and there is no liability of the truck accidentally slipping. The extensible section is adapted to be moved inward .to'arrange it compactly, as shown in Fig. 2 of the drawings, and in this position the transverse.con-- nectingrbar'of the extensible section will lie above and fit snugly within the upper or rear face of the transverse connecting portion 5 of the fixed support. The'wheels'of the truck are of the ordinary construction and are 2to provide openings or spaces for rotary tween which the braces are located.

screws 16, which have reduced ends 17 and which are journaled in suitable bearings of the front and rear transverse bars of the truck-frame. The longitudinal bars are connected by suitable braces 18, having their terminals bent at right angles and secured to. the inner side edges of the said bars 15, b}?- T 0 space between thelongitudinal bars 15'is to form a casing for the gearing hereinafterexplained, and this casing is ofiset from the upper edges 21 of theside bars 2 to provide a space for folding the hoisting mechanism when it is desired to use the truck as an ordinary hand-truck, as hereinafter explained.

The rotary screws, 16, which, are located at,

opposite sides of the truck-flame, engage traveling

nuts

22 and 23 of a vertically-mov.

able carrier 24', which is provided with 'a fold" able support 25, adapted to extend from the frame of the truck, as clearly illustrated in Fig. l of the drawings, to receive the goods to be raised or lowered. The carrier, which slides longitudi nally of the truck-frame, is provided at opposite sides with bars 26, which are connected by an upper cross-bar 27 and by a lower rod 28, forming a pintle for hinging the foldable .support 25 to thecarrier;

. The pintle-rod 28 pierces the side bars 26 and the sides "of the hinged support 25, which consistsof an approximately rectangular frame.

The frame of the hinged support consists of g a bar bent at opposite sides of the center at right angles to form two sides and a transverse connecting portion. The sides, which are also,

gmnected by a brace 29, are reinforced at ieir inner portions by bars 24 and are provided at their inner ends with'heels 30 for engaging the side bars 26 ofthe carrier. The

vide openings to receive the side bars 26 when the hinged support is folded. The inner ends of the reinforcing-bars are connected with the heels 30, and the outer'ends of the reinforcing-bars are angularly bent and secured to the sides of the support 25 in any suitable manner. The lower ends of the side bars 26 Ofthe carrier are recessed to provide curved edges and shoulders 30 for engagement with the heels 30 of the hinged support. The

hfnged support may be locked in its folded;

position by catches 25", mounted on the sides of the support 25 'and each comprising a beveled pin or bolt and a spring for actuating the same. The bolt or pin, which is adapted to engage an opening 26of the adjacent side bar 26, is. secured to the spring at one end there I of, and the spring is fastened at its other end to the side of the support 25; The spring projects slightly beyond .the pin to enable it ,bent at right angles and secured to the sides i of the same; The carrier is' provided with a pair ofhinged guards 31, arranged to slide on the front plate 19 of the casing ofthe handled from-coming in contact with the said plate 19, 'These guards, which consist of bars, extend beneath the connecting-bar 27 and. are .provided at their lower ends with 'eyes 32 for the reception of the pintle-rod,

whereby they are connectedwith. the ,carrier. Also the guards are adapted to extend above the transverse bar- 14 to provide a back support for the goods when the carrier is raised to or near the limit of its upward move- In order to enable the carrier to move freely,

it is provided at the front of the truck with a pair of a'ntifriction rollers or wheels 33, arranged on the pintle-rod and adapted to run on the front plate. The )intlerod also receives spacing-sleeves 34 an i 35, arranged, re-' spectively, between the two guards and between the antifriction rollers or wheels and the sidesof the foldable support. The nuts 22 and 23 are arranged in pairs, and the up truck-,fgame and adapted to prevent the goods covered-byfront and back plates 19'and 20 i its rier holds the rear antifriction devices in con-- cred.

rier to be raised and lowered with a minimum amount of friction. ing the truck in a horizontal position are spaced from the inner side faces of the side bars 2- to enable the rear antifriction devices to pass them; but they may be mounted on the frame of the truck in any other desired manner, as will be readily understood.

The rotary screws 16 are provided at their lower ends with miter-gears 39, which mesh with similar miter-gears of short transverse shafts 41, journaled in suitable bearings of the longitudinal bars 15, and in bearings of a bracket 42, which is secured to the front transverse bar 13. The inner ends of the short transverse shafts are also provided with miter-gears 4E3, which mesh witha miter-gear as} of a central longitudinal shaft 45, journaledin suitable bearings of the brace 18. The inner or upper end of the central longitudinal shaft this provided with a beveled pinionfi, 'which meshes with a beveled gearwheel N, keyed or otherwise secured to a iort shaft 4C8, which is journaledin suitable bearings of the front and rear plates 19 and 20 of the casing of the truck. The rear end of the casing is preferably reinforced. by a transverse plate 49, or any other suitable means may be employed for providing rigid bearings for the gearing. The shaft 48 which -constitutes an. operating-shaft, 18 ex- -te nded rearward and provided with a polygonal portion 50, which carries a spur-pinion 51, which meshes with a large gear-wheel 52 of a second operating-shaft 53, which is journaled in suitable bearings of the front and rear plates 19 and 20 and the re1nforcing- The second operating-shaft has'anplate 4:9. extended polygonal portionfor the reception of a cranl -hand1e 54, which is adapted to be placed on either of the pperating-shafts and which when not in use is held at the baelcby a spring clip or clamp 55, as illustrated i-n Fig. *2 of the drawings. The upper or first operatirig-shaft .33 is adapted to be .enn'iloyed when handling light loads,and it will enable the 'vertically-movable carrier to be rapidly raised and lowered. The second or loweroperatingshaft is employedfor handling heavy loads, the gearing will afford great power and will enable heavy leads to be easily raised and low W hen either of the shafts is rotated, motion is communicated tln'ougl'i the gearing to the longitudinal screws, which are rotated for causing the traveling nuts of thecarrier to move upward or downward, according to the direction in which the screws are rotated. i'l' hen the hoist not in use, the hinged support'or member of the carrier is adapted to be folded upward or baclnvard to the position illustrated in full lines in Fig. 2 of the draw: lugs, and wh n in its folded position it lies between the sidebars 2 of thetruck, between the casing and the front edges of the side bars,land

is arrangell wholl; withinjthe said space,

The legs 38 for supportwhat I claim as-new, and desire to whereby the truck is adapted to be employed as an ordinary hand-truck When folded, the movable support is located entirely out of contact with the goods handled by the truck and thereis noliabilityof the hoistinterferingwith such goods or being injured by the same.

Any other form ofgearing may be employed for transmitting motion from the operating device to, the rotary screws, and the'lat-e ter may be constructed of any desired length to enable the goods to be raised or lowered the desired distance.
