Application filed October 7, 1914. Serial No. 865,416.

T 0 all whom it may concern:

Be it known that I, FRANK A. Moore, a citizen of the United States of America, residing at lVyandotte, in the county of lVayne and State of Michigan, have invented certain new and useful Improvementsin Trucks, of which the following is a specification, reference being had thereinto the accompanying drawings.

' This invention relates to lifting trucks of the type in use in warehouses, stores, docks or the like, and more particularly to means for lifting barrels,

sheet metal type, baskets, bags and the like, clear of the ground without the necessity of the opera-' tors removing his hands from the truekto tilt hacker to drag the article to be loaded onto the truck. The invention also includes means whereby the truckis adjustable to op erate regardless of their size. A further feature is an arrangement of the device whereby a stackof bags, crates or the like may be lifted from the ground without tilting the stack sufiiciently to displace the individual parts thereof. i

T he invention consists in the matters hereinafter set forth and more particularly pointed out'in the appended claims. 1

In the drawings, 7

Figure 1 is a viewin front elevation of a truck that embodies features of the invention; Fig. 2 is a viewin side elevation thereof; Fig. 3 is a plan view of the truck; Fig. e is a view in rear elevation of the truck; I

Fig. 5 is a view in perspective showing the method of picking up a standard barrel by the truck without the all of the operators hands; I r e Fig. 6 is a view in front elevation of a truck designed for underrunning and'lift-' ing a sheet metal package, or abag;

Fig. 9 is a View and in detail of truck jaw Figi lO-is a view in perspective showing a truck in position for loading and trundhngr a basket or the like.

Referring to the drawlngs a frame of standardconstruct on 18 formed in any preeither of the old standsuccessfully on articles of thisnature,

fixed or rotatable, as preferred, on a pair of suitable bearingwheels I A pair of oppositely disposed jaws 6 have upwardly extending, suitably proportioned arms 7 that are slidably mounted on a cross guide member 8 which may take the form of r atruss rod, so that the jaws may toward or from each other to embrace or under-run objects of different sizes. The jaws are disposed in a plane transverse to the plane of the main frame and close to the ground on wluchthe bearing wheels of the trucks rest in such position that when the handles are practically in Fig. 9- for example, the-jaws are substantially parallel to the ground. Furthermore they are preferably disposed to be very close thereto; Its a further feature of preferred the inner peripheriesi) of the jaws are curved to form a substantially true semi-circlewhen the jaws are closed, while the outer portions 10- thereof converge slightly beyond the center of'curvature A- member 11 is longitudinally reciprocable on the main frame near the lower en thereof, a clip 12 anda stud 13 that passes through a longitudinal slot 14 of: the member, acting as'guide's. A pair of divergent guide slots 15 on the member 11 are engaged by studs 16' each secured on a jaw arm 7, the

parts being so disposed that movement ofthe guide downward forces the aws together while the action of a retracting spring 17 in tension between the upper end portion of the member 11 and a suitable part of the mainframe, in drawing the memberll upward, tends to move the jaws Slapart. ily engaged by the foot of the user, as lndicated in Fig. 5, affords means for depress- 7 ing the member 11 and the jaws and a suitably arranged dog '19 that engages the notched margin of thereby contracting the adjacent portion of-the member ll locks the-latter in depressed position,

In either construction the arms are so disposed that if they underrun an, object, they engage it when the truck is tilted back. at a point. beyond the center. of gravity or depressing of the truck handles is to tilt back the object firmly on to the truck and thereby hold it; in position to be readily balanced and trundled without the necessity of other handling by the operator.
