1 Claizn.

The present invention relates to new and useful improvements in hand trucks and more particularly to a device of this character adapted for handling milk cans for the purpose of transporting the can from place to place without subjecting a person to the strain of lifting and carrying the can.

An important object of the present invention is to provide a hand truck of this Character embodying a yoke for engaging and supporting the neck of a milk can and pivotally carried by the truck to support the can in a suspended perpendicular position while the truck is being moved from place to place.

A further object of the inventon is to provide a can neck supporting yoke of this character arranged to engage and support the neck of a milk can by a tilting movement of the truck and to lift the can in its supported position without requiring the lifting of the can bodily by a person.

A still further object of the invention is to provide a hand truck of this character of simple and practical construction, which is strong and durable, efiicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a side elevational view showing a milk can supported in position on the truck.

Figure 2 is a simliar View showing the truck tilted in position for engaging and lifting a milk can into a position for supporting the Vcan on the truck.

Figure 3 is a horizontal sectional view taken on a line 3-3 of Figure 1.

Figure 4 is a similar View Figure 1.

Figure 5 is a fragmentary front elevational view of the upper portion of the truck frame and with parts shown in section.

Figure 6 is a fragmentary Vertical sectional view of the adjustable foot for the truck taken on a line 6-6 of Figure '7.

Figure 7 is a sectional 1-1 of Figure 6, and

Figure 8 is a sectional View of one of the bumpers for the can taken on a line 8-8 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed taken on a line 4-4 of view taken on a line Ll O a preferred embodiment of the invention, the numeral 5 designates an inverted U-shaped truck. frame, preferably constructed of tubular material having T-fittings 5 secured at its lower ends by rivets or the like l, and in the lower ends of which are threadedly received adjustable extensions or feet 8 having bearing blocks 9 welded or otherwise suitably secured to the lower ends thereof and on which Wheels w are journalled, the Wheels preferably being of a rubber tired construction.

A semi-circular frame I likewise of tubular construction has its ends connected to the T-fittings 6 and extends horizontally from the rear of the frame 5.

A tubular socket |2 is welded or otherwise suitably secured to the rear edge of the frame I and reinforced by webs |3 welded to the frame and to the socket I'2.

A handle |4 of tubular construction is inserted through the socket |2 and welded in position thereto, the lower end of the handle extending below the socket to form a prop 15 to normally support the frame 5 in approximately perpendicular position, the upper end of the handle being curved rearwardly and provided with a hand grip IG.

T-iittings I'I are secured to the upper portion of the frame 5 at each side thereof by means of rivets or the like I 8, the fittings I'l having one end portion projecting horizontally inwardly to form tubular bearings 19 for trunnions 20 projecting outwardly at the opposite sides of a U-shaped yoke 2|, the trunnions providing a pivotal mounting for the yoke at the upper portion of the frame 5.

The yoke 2! has its curved bight portion projecting rearwardly and the trunnions 20 are positioned to off-balance the rear portion of the yoke so as to normally cause the rear portion of the yoke to tilt downwardly. 'Stops 22 are positioned between the bearings 19 and the trunnions 20 to limit the downward tilting movement of the rear portion of the yoke.

The weight of the handle Ill and frame II norz mally causes the prop |5 to rest upon the ground so as to support the frame 5 in a slightly rearwardly inclined position when the truck is not in use.

When it is desired to place a milk can '23 on the truck the handle |4 is raised upwardly and the frame 5 tilted forwardly as shown in Figure 2 of the drawings and the yoke 2| moves into position to engage the neck of a can.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the coni Wheels on the lower ends of the frame, a yokeV secured to the lower endrof the frame, a handle connected to the yoke, and a U-shaped lifting yoke in the upper part of said frame for straddling a mlk can neck to lift the can by the neck and suspend the same, said lifting yoke being pivoted in said frame and overbalanced on its pivots to normally assume an angular position relative to the frame, said frame being tiltable forwardly by said handle about the axis of the Wheels to lower said lifting yoke in the normal position of the same and dispose the lifting yoke in horizontal position for straddling the neck of the milk can and whereby, upon tilting of said frame rearwardly, said can will be lifted and suspended by said lifting yoke, the yoke at the lower end of said frame straddling the lower end of the can and preventing undue swinging of the can when the frame is tilted rearwardly.
