y is particularly adapted for the transportation of heavy objects, especially ashcans, up-and down flights of stairs.

. vided with means,

More specifically my invention resides in a handtruck which is so constructed as to operate on level surfaces in the same manner as an ordinary handtruck and which is pronormally so arranged as to provide no impediment to the normal operation of the truck, for coacting with the tread of a flight of stairs for lifting or lowering the truck with its load, such means being of a nature to relieve the operator of the my device;

. stud 5 (shown in Fig. 2 as the upper labor normally encountered in this operation. This lifting and lowering means can, of course, be so designed as to still further relieve the operator.

The object of my invention is to improve the truck shown in my Patent No. 1,839,317. The nature of these improvements and the further objects and advantages of my invention will appear more fully from the following detailed discussion of the accompanying drawing in which:

Fig. 1 is a front elevation of my device with the lifting means out of operative position;

Fig. 2 is a detail of part of the frame of Fig. 3'is a plan view of my device in the position shown in Fig. 1; i

Fig. 4 is a side elevation of my device at the beginning ofthe lifting operation; and

Fig. 5 is a side elevation of my device at the end of the lifting operation. Referring to the drawing in detail 1 represents the frame which is made of a metal rod or tube of any cross sectional shape which is i bent to form the nose 2'and cradle 3 of the truck. This bending is done in such a way as to leave one of the free ends of the rod or tube longer than the other. At the upper end of the cradle the free ends of the rod or r tube are arranged in juxtaposition to each other, the long free end being bent to form a handle 4. The free ends meet below said handle and overlap in such a manner that either of them can be turned-up to forrfn a ree invention relates to a handtruck which 1532. Seria1 n. 5 8,10

When secured by the stud the lifting rod is held tightly in position by reason of the fact that the' spring 9 must be slightly extended in order to permit the engagement of the stud by the rod 8.

The operator can then kick the rod 8 into reengagement with the stud 12 and proceed without impediment along the level surface. This construction offers the important ad vantage over the construction shown in my aforesaid patent that when the lifting rod is out of operation it is not necessary to keep the spring under full tension whereby the life of the spring 7 Whereas in my prior construction I secured the lifting rod out of position with a sepa rate locking member, I secure the lifting rod in my present construction out of operating position by a slight tension of the spring itself. oreover, my present construction eliminates the need for brackets arranged on the body of the truck to prevent the free end is considerably prolonged.

In testimony whereof I have hereunto set my hand.

of the lifting rod from swinging when said rod is out of operative position.

Having thus described the nature and objects of my invention and illustrated a specific embodiment of the same what I claim as new and desire to secure by Letters Patent is:

1. In a handtruck having a frame with an axle at its lower end, a pair of wheels mounted 011 the axle, a lever connected to the upper part of the frame and a lifting rod having one end connected to the lever and the other end adapted to coact with the tread of a stair way, means for imparting a lifting force to said frame comprising a spring having one end attached to said lifting rod and the other end attached to the body of said truck, and means for securing the said lifting rod out of operating position comprising a stud ar ranged on the bodyof said truck and adapted to coact with said rod in such a manner that when the rod is placed in engagement with said stud it is held in that position by the tension of said spring.

2. In a handtruck having a frame with an axle at its lower end, a pair of wheels mounted on the axle, a lever connected to the upper part of the frame and a lifting rod having one end connected to the lever and the other end adapted to coact with the tread of a stairway, a spring having one end attached to a predetermined point on said rod and the other end attached to the frame of said truck near its axle and a stud projecting from the body of said truck at such apoint that when the lifting rod is swung into the body of said truck out of operating position it can be placed in engagement with said stud only by placing said spring under a slight tension suflicient to hold said rod in engagement with said stud.

8. In a handtruck, in combination, a frame constructed of a single rod bent to form the nose of the truck, the cradle and the handle, the free ends of said rod meeting at a point below the handle of said truck and one of said
