as extending upwardly somewhat above the bed of the'truck. To'prevent sinking in soft ground the main supporting wheels 4 are provided with wide rims or tires, and

for facility in going up and down stairs these wheels are made relatively large in diameten Some usual and convenient form of axle 5 is provided for wheels preferably arranged back f'ronrthe heel'piece 2 so as to be beneath the center of gravity of a load of averagesize. The

frame or bed of the truck comprises side bars '6' between which are connected the carrying straps 7 slightly curved downwardly as is common toaccommodate loads of different shapes or sizes. In order to enable the truck to be used on walks. on paths.

which are narrower than the distance betweenthe two main wheels, and in order to facilitate movingthe loads up and down stairs or over bhtnpsfthe relatively small pilot wheel 8' is adjustably mounted beneath 1 the frame and behind the main wheels. For

purposes of adjusting-the pilot wheel to and from the frame and. the side wheel's its foreframe 9 is pivotal l'yattached at lO tothe underslung main wheel axle The rear supporting member 11 of the pilot wheel is adjustably connected with thencro'ss bar 12 {by means of a plurality of perforations 22 arranged in the member 11 for selective cooperationwith the 'pin 23 Thus it will be seen that by moving the pin 23 inthe cross member 12in the different perforations 22 of the member 11 the pilot wheel will be raised or lowered from the ground-about the pivot-"10.v g I V Pivotally secured tothe member 12 1817116 arm 13 provided at its outer end with the downwardly extendingprongs orhooks- I5 and 16 which are arranged onein front of the other longitudinally of the truck: Although the hooks have been described as being one in; front of the other it: will be mounting the handles 3 and adjustable prong l8.

understood that one of them may be placed at the side but still ahead of the other. Adjustably secured to the arm of 1.3 for movement along he me is the depending hook or priin'ig l? which is :n'iapted for cooperation with the tops of v rious sizes of loads to retain the same shown in Figure 3. A similar sort of ad iust' able hook or prong 18 is also movable along the arm 13 for purposes of retaining a second load in position should such be car-' 'attachinent to the cross bar 12 so as to lessen the tendency to any sidewise flenn re. The load to be carried by the truclr has been illustrated in the form of a cylindrical container or barrel 20 but it willbe understood that other forms of loads oroontainers are adapted to be carried by this truck. The widened end leof the arm 13 affords an appropriate rest for anotheror smaller container 21 which, as sl1ow11.inFig1ire 2, may bepositioned on the arm 18 between the Seoured by rivets 25 to the cross bar 12 is the sup. porting member 24. for the-rear supporting member ll of the pilot wheel as is illustrated in Figure 5. i y

Among the advantages of any device may be stated that the truck is adapted to load. and unload-containers without the necessity for lifting one edge or the entire body of the container or barrel directly by hand as is usual. Froml igurel it will be-seen that when the truck is wheeled upagainst the barrel to be loaded, the arm 13 may be moved down so that the upper edge of the barrel engages between the prongs l5 and 16 thus" enabling the arm 13 to be pushed to j tilt the barrel when, after one edgejthereof is raised, the heel pleee 2 may be nserted beneath the raised edge. If desired the handles nay be then lowered and the barrel carried in the p'ositionshown in Figure 2 by means. ofthe heel piece. and prongs l5 and 16 of the arm 13. Ifit isdesired. to carry the load in the manner indica ed: by Figure 3 the barrelQO. may be loadedin the conventional way,- or;

it may be brought to this positionjfromthe position indicatedin Figure 2 by lowering the handles, disengaging the arm. 13. from the top-of the barrel and allowing the same to fall back upon the carrying straps 7. Attention is directed to the fact that when large wheels with wide rims are selected, soft ground and steps may be transversed with greater facility Whentwo loads are on the, truck as.

carried as shown in Figure 2 it will be apparent that the wheels are substantially midway between these loads. Thus a good distribution of weight is secured at all times. whether the load be in the position shown in Figure 2; or in the position shown in Figure 2. The use of an adjustably mounted pilot wheel 8 helps movement of the truck over bumps and along a path'of less width than the distance between the main wheels. Probably the most noteworthy advantage of my truck is the ease of loading and unloading. i

The pilot wheel and. its mounting is an additional advantage in going up and down steps, when the same may be used as a pivot and lever. By having the handles extender curved upwardly as shown a rest or abut ment is formed for holding the second container in place on the pivot arm.

{ claim as myinvention:

1. The combination with a frame of a heel piece atone end thereof and anop'erating handle at the other end, a hook arm provid ed with. a plural-ity of prongs and plvotally secured to the frame, said hook being adapted to engage the upper edge of an object constituting the load between said prongs for retaining the same on the outer edge of the heel piece, and an upwardly extending prong adjustable along the hook arm to lit different sizes of loadswhichmay be carried .11 pon said arm between the operat inghandle and. the last mentioned prong.

52-..The combination with a frame of an operating handle therefor. heel piece at one end of said frame adapted to support an article. a pivotal hook arm secured to the frame adjacent the. operating handle, to maintain. said article upright and-adapted to itself support an additional article, and a pair of supportingwheels er. relatively large diameterlocated. substantially midway between the point .ofattaohment of the hook arm and the heel piece and adapted to assume aposition below and between the two articles carr ed when both are in uppos tions.

porting wheel and axle'by 'which said "frame in a truck the combination with a frame 'ofan operating handle therefor at one end ofthe frame, a relatively large supis carried, a smaller pilot wheel seturedfbiaeath. the frame and between the larger wheel" and the handle and having support- 1 member pivoted to theaxle v and means tor adpisting the pilot wheel on its pivotto regulate the height of-the pilot wheel from the frame and axle of the larger wheel.

I 4C: In a truck, the combination with a frame provided with an axle and main wheels and with an operating handle at one end, of a pilot wheel located between.the

aXleand handle and havinga pivoted supporting arm and anadj'usting armcon'n'ected to the pilot wheel and cooperating with the frame to swing it on its p vot and regulate its distance from the frame.

ing arm pivoted to the yoke of the axle, and

means for adjusting the supporting arm on its pivot to regulate the distance between the pilot wheel and frame.

6. In a hand truck, the combination with a pair of ground wheels and a frame pivoted thereon and having a heel at its lower end adapted to engage beneath the edge of a barrel at a point well forward of the wheel and to lift the barrel, of a yoke arm con nected to the frame above the wheel pivots and adapted at itsouter end to cooperate with the upper portion of the barrel to hold it upright and against tilting when raised by the heel, the inner arm being yoke shaped to suppert an additional load, and retainingmeans for holding an additional load on the yoke arm.

I. In a hand truck, the combination with a frame having a heel at its lower end adapted to engage beneath the edge of a barrel and a handle portion at its upper end, of means connected to the frame and adapted to cooperate with the upper portion of the barrel to hold it upright and against tilting when raised by the heel, said means itself constituting carrier for another object and being provided with means for confining such other obj eot between itself and the handle portion.
