HAND-TRUCK.

Specification of Letters Patent.

Patented July 14, 1914.

a citizen of the United States, residin at Schenectady,- county of Schenectady, ,tate' of New York, have invented certaln new and useful Improvements in Hand-Trucks, of which the following is a specificatlon.

The present invention relates to handtrucks and more especially to. receptacles and trucks for containing and transporting masses of small metal articles from place to place in a manufacturing establishment.

One of the most uncertain and variable items of expense in practically all factories is the cost of porterage or transference of small parts about the plant in their ordinary evolution from rough castings or forgings to finished articles. In order to overcome or reduce in a practical manner this general expense, I have produced a receptacle designed to contain a substantial quantity of articles and a hand-truck whereby such receptacles may .be directly picked up, conveyed and discharged without speclal skill or great effort on the part of the laborer.

For a more complete understanding of. my

invention, reference may be had to the ac-.

companying drawing forming a part of this specification, in Which-- Figure 1 is a side elevation of my 1mproved hand-truck and receptacle; Fig. 2- 1s a plan View thereof; and Fig. 3 is a righthand end elevation with parts broken away.

The receptacle is in the form of an oblong box 1- of iron or other rigid material, with a tflat stiffening rib 2 about the upper edge and flat grip-plates 3, notched or ribbed at their lower edges 4, secured centrally of the longer sides thereof.

The truck consists of two flat side levers 5 centrally connected by diagonal cross-stays 6 and stiffened by a brace 7 connected by a rivet 8 to the stays 6 at their point of crossing and having its outer ends bent downwardly and riveted at 9 to the feet of V- shaped legs 10 riveted to the respective levers 5. All these parts are preferably of 11'01'1.

The rear ends of the levers 5 are reduced in width and curved downwardly and provided on opposite sides with rounded strips 11 of wood or metal held in place by through rivets to afford comfortable handholds or grips. The lower ends 12 of the levers 5 are bent up at an angle and each is provided at its end with a pair of spaced Application filed February 10,1913. Serial No. 7%,417.

knobs 13, to he referred to later. Each.

lever 5 is provided at or near its angle with an outwardly projecting stub shaft :14: on

fwhl'ch is journaled a wheel 15 held by suitable 'means such as a cotter pin 16. The

truck is constructed with the space between the levers 5 somewhat greater than the total widthof the receptacle to afford clearance and the outer ends of the bent up portions 12 bent inwardlysomewhat as indicated in Fig. 3 so that they will have a space between them greater than the lower portion of the receptacle and less than the total.

It will be observed that the lower portion of the truck is entirely unobstructed between the levers 5 and accordingly may be caused to approach the receptacle by either forward or backward movement. Upon lowering the handles when the ends 12 are about midway of the receptacle, the innerv knobs 13 will first engae recesses in the ribbed grip-plates 3 and y the turning of the levers 5 about their fulcrums, the stub shafts 14, the receptacle will be raised at the end nearest the truckman, and as the bandles' are forced farther'down the outer knobs 13 engage the grip-plates 3 and cause the receptacle to tilt therewith until the handles are lowered to about the inclination shown in Fig. 1 when the receptacle is positively supported in elevated position ready to be.

moved about. The grip-plates. 3 are provided with a number of ribs or notches so that in case a receptacle be not uniformly loaded the truck may be adjusted forward or back so that the center of gravity of the receptacle and contents shall fall between the front and rear knobs 13.

I do not desire to restrict myself to the particular form or arrangement of parts herein shown and described, since itis apparent they may be changed and modified without departing from my invention.

What I claim as new and desire to secure by Letters Patent of the United States, is,-

1. The combination of a receptacle provided with grip-members having series of notches therein, and a truck having bifurcated arms cooperating with a pair of notches in each of said grip-members to elevate and positively position said receptacle.

2. The combination of a receptacle provided on opposite sides near its upper edge with grip-members having series of notches in the lower surface thereof, and a handtruck comprising two angular levers having splayed out ends cooperating With-pairs of arms ofunequal length to cooperate with notches in said grip-members to elevate and said notched surfaces-to elevate and steady positively position said receptacle upon said receptacle upon lowering the long arrns forcing the free ends of said levers downof said levers. 6 wardly.
