@and the principal ubject 'iof the invention is vto facilitate converiientxand iexpeditious =transportationzof relatively r'large "and ibulky articles such as stoves; refrigerators, etc'.,.:-as well ts groups of relatively smalleriarticles such asiboxes,fcans,fand the like.

This object :is rachieved :byt'he" provision of "the instant apparatus consisting of a pairio'fiframes which are radapted to fib'e clampedagainst oppositex endsrof ahe articl'e whirihis to ibetransported and which aretproui'ded with ground engaging wheels' zor rollers, together with-means for araising the :article "to 'anuelevated position whereupon the: entire unit, that .is,; the frames and the article therebetween; may be easily rolled along theground.

The primary featureiof ithesinvention resides, therefore; in the particular istructuralwarrangement of the aforementioned frames, while other features lie-in 'thexmeans' which are employed for clamping :the- "frames against the article' and a means for elevating the sarticle' -af'ter itherframes have been appliedthereto;

some of the advantagesnof the-invention reside in its simplicity of iconstruction inits convenient operation, andits" adaptability to economical manufacture.

With the :a-b'ov'e'more important objects an features in view and such other objects and features as may become apparent asthis specification procee'darthe invention consists essentially of the arrangement and construction of parts as illustrated inthe accompanying. .drawings, in which:

' Ei'gur e'S is-"a' tOp plan'viewcfTthe subjeot shown Bike characters of reference are employed "to designate like parts in the specification :an'd \throug hout the several views.

Referring now to the accompanying "drawings detail, "the invention consists of an article transporting "apparatus designated generally by the reference character ll lL th'e same embodying in its construction apairor vertically elongated "frames designated generally by the reference character n, these loeing identical in construction sothat a descr iption of 'one will suffic'e' for both.

The "frames in aref of an inverted U=shaped configuration affor' g' a pairrof spaced uprights l 4 *'and-a ting bightportion l'fi at the uper endiof the prignts, the lower end portions of the uprights being provided "with suitable brackets IB in which is "rotatably mounted a ground-engagingrifller at.

An article carrying member designate'd gen-- erally by the reference chajracte'r 22" is slidable vertically on the' u rignts lt, tliismember "con- 'sis'tin'g or a pair of sleeves "2n which are "slidably positioned on theflipriglits M and are rigidly connected t'dgethr by a'1i6r inta1 angle ba Ir ZG and by an additional cross-piece 28 which is spaced upward-ly fromtheangleioar, as shown.

Substantially tubiilar spacers -30 are secured to lower end portions of the sleeve's 24 andgare provided 'with eldngatedeyes 32, and it should be explained-that when the "invention is placed in use, the two frame assemblies 12 are placed against opposite ends' ofthe article which is to be carriemsuch as for example; a stove '34, so that the-"lower cdges'o'f th e article rest upon the angles 26 while the cross-pieces 28 abut the end surfaces of the article, "as is best shown Figure 1 Ti desired; suitable resilient pads 36 may be interposed betweenthearticle and the sleeves 24 so as to maintain the lower end portions of the sleeves at 'afd'ils'tance from the "article toprevent possible scratchingtor-marring or the latter. The frame assemblies 12' are clamped against the opposite ends of the article 34 by a flexible element in the form of a belt or strap 38 which is simply threaded through the eyes 32 and the ends thereof are connected together by a suitable buckle 40, so that the frame assemblies together with the article being transported assume the form of an integrally movable unit.

It may be also explained at this point that in 3 order to facilitate lowering of the article carrying members 22 to a sufficient extent to permit the angles 26 to be inserted under the lower edges of the article 34, lower end portions of the sleeves 24 may be provided with upwardly extendin slots 42 (see Figures 4, 5 and 6) whereby the sleeves 24 may slide downwardly on the uprights I4 beyond the upper edges of the brackets I8. I I p Means are provided for sliding the article carrying member 22 on the associated uprights 14, these means consisting of a pair of lovers 44 which are pivoted to upper end portions ofgether for simultaneous swinging movement by a cross bar 48, the levers 44 being equipped "with a plurality of upstanding pins -56- which are adapted to be engaged by suitable eyes 52'pr'ovided at one end of a pair of flexible elements or chains 54. The remaining ends of the chains 54 are suitably'anchoredjto the angle-bar 26 as at 56, it being apparent from the foregoing that when the levers 44. are'swung upwardlyas atv 58, the carrying member 22 will be slid upwardly ontheuprights 14, thus raising the article 34 therewith. Needless to say, by engaging the eyes 52 of the chains 54 withthe differentpins 50,

the mechanical advantage of the levers 44 may bevaried so as to suit articles of different weight.

In addition,means are provided for locking the carrier members 22 in their elevated position, these means involving the provision of locking pins 60 which are insertable in apertures 62 provided in the sleeves 24 and are selectively receivable in vertically spaced apertures or bores 64 with which the uprights l4 are equipped, so that when the carrier member 22 is raised to an appropriate height, the locking pins 66 may be inserted inappropriate apertures or bores for the purposeof supporting the carrier in its elevated position. If desired, the looking pins 66 may be provided with suitable cords 66 anchored as at 68 to the sleeves 24 so as to prevent their loss. I r In 'anyevent, it is to be noted that after the carrying members 22 and the article 34 have been raised to an elevated position, the entire apparatus, together with the article, may be easily rolled along the ground until a destination is reached, after which the lockin pins 60 may be withdrawn and the levers 44 actuated to lower the members 22 and the article 34 to the ground. It is to be also observed that while the transportation is being effected, the levers 44 will function as effective handles for pushing, pulling, steering and guiding the entire apparatus.

Moreover, when the handles are in their upwardly swungv positions, the entire device may be lifted thereby from the, ground and conveniently carried.

It may also be explained that the primaryfunction, of the spacers 30 is to provide clearance for the chains 54 without interfering with the belt orstrap 38. 1 V i The-foregoing disclosure describes the invention as used for transporting relatively large, bulky objects, such as stoves, refrigerators, etc" the uprights 14 as at 46 and are connected to-;

4 but attention is now directed to the accompanying Figures 7 and 8 which illustrate the invention being used for the transportation of groups of relatively small objects such as cans, boxes, etc. In such instances, a platform 10 is simply positioned on the angle bars 26 of the frame assemblies [2 while a tie rod 12, provided at the ends thereof with suitable clamps 14, is attached to the bight portions l6 of the frames,

Sso that the frame assembliesi'are maintained in a spaced relation and'are clamped against the opposite ends of the platform 10 by the strap or belt 38.

v; In this-instance, the platform 10, in eifect,

constitutesa portion of the load which is to be A transported and which is positioned on the plat- 3 form, as will be clearly apparent.

It is believed that the advantages and use of the invention will be readily understood from the foregoing disclosure and accordingly, further descr'iption-thereofr-at-this point is deemed unnecessary. r

While in the'foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the, details of construction, combination' and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as-new is:

In an article transportingapparatus, an inverted' substantially U'-shaped frame affording a pair of uprights and a connecting bight portion at the upper. ends thereof, a ground engaging roller rotatably mountedat the lower end of each of said uprights,'anarticle carrying member including a pair of spaced sleeves slidable on said uprights and an article engaging crosspiece rigidly secured to and between said sleeves,

means onsaid sleeves for' clamping said member against'one end of an article to be transported, means on said frame for sliding said member relativethereto, further means for locking the member in an elevated "position on the frame, said means for slidingsaid member including a vertically swingable lever pivoted on the frame adjacent to the bight portion'of said frame, and a flexible element operatively connecting said lever to said cross-piece, said lever extending horizontally from one side of the frame and comprising a handle'when the lever is in the position assumed when said member is raised.
