Referring in detailto theydrawivngs, the improved bar row therein shown comprises an elongated substantially rectangular open frame' 10 made up of 'twin"si`d'e, pieces 11 which at one end of the frame, have deected end portions which afford, wheelbarrow-like handle ymembers 12. Said twin side pieces 1,1. are shown in Fig,` 21 as i Y tubes, square in cross section. At the end thereof. op'-A One object of this. invention isy .to provide a type of n barrow ory truck so` constructed that a pair. of them can have a trunk or like article strapped into` place between them, so that, when carried upor down stairs by two persons in tandem fashion, the uppermostv person; can grasp the handle means of one barrowv and the person inthe rear can support. with-v both vshoulders and hands,

the handle means of the other barrow, and thusI con'- veniently transport a trunk or other largearticle, for example a refrigerator, up or down a flight of stairs.

A more specic object is tov provide an' improved latch ingv means for maintaining the aforesaid-- shoulder supportable handles in a retract-ed, position, when not in use; and to provide for adjustingv the.y latter handles at various distances apart to accommodate, between them, the different sized necks of persons usingthe device.

Still anothery object is to provide improved combined mounting and latching meansY for swingably attachingand holding retracted certain. ofl the handle members of the barrow and at the Sametime enhancing the accessibilityv thereof. Y

Yet a further object of the invention is to provide means for adjusting the shoulder supportable handles at Various inclinations with regard to the hand graspable handles to accommodate the stature of different individuals wherein the weight of the article. being carried can be more evenly distributed between the shoulders and the hands of the person carrying the greater-portion of the load.

This application is a continuation in .part of my copending application tiled December i4, 1951*, Serial? No. 261,700, now abandoned. l

Other objects, advantages and features of invention will hereinafter appear.

Referring tothe accompanying drawings, illustrative of a preferred, reduced to practice. embodiment of the invention,

Fig. 1 is a front elevation of the device.

Fig. 2 is a fragmentary, rear perspectiveview on a larger scale of the twinA handle carrying and locking means.' l

Fig. 3 is a side elevation of the device with its upper pair of handles in a folded or retracted condition, and its lower pair of handles in their outswung, extended position, in which position they are in use to maintain the device in an upst'anding position, ready to be loaded.

Fig. 4 is a side elevation of the device similar to Fig;

posite .to said wheelbarrow-like handle members said frame is providedA with a horizontal basal 'member 13 which is of an inverted T in. cross section thus provid.- ing it. with fan attaching 'ange. 14 and shelfj anges. 1.5J and 15a, the latter ilange affording` a baggage support.

In its midlength portion the frame 10 Carries a channel shaped crosspiece 17 which unites and braces its side pieces 1.1. This crosspiece, viewing the barrow in its operative position, hasy its4 flange portions 1.8 and 19 directed rearwardly from, its web 20.. A. shaft 2.1 (see Fig, 2), located between and extending parallelto said flange portions, bridges. the space. between the aforesaid tubular side pieces, 11a. The midlength port-ion of said shaft 21 is contained friction tight within a sleeve 23 which; is secured to the web. 20 by aweld 2311-1 'The general structure. of the4 frame. 10.A is` completed by atrans.` verse, brace bar 22 which is located between the, aforesaid crosspiece 17 and. the. handle4 carrying endof the A medial handle,v forming bar 25 is slidably andfswingably connectedwith each end. portion. of the. aforesaid shaft 21,I said handle forming barsswinging. between two.k positions, in one of which they are directed toward the basal end of the barrow and in the other. of which they project at substantially a right-angle. to the length of the barrow. The swing of said handles 25` toward` the basal end of the barrow is. limited by` the. innerend portions `of said. handles coming intol contact with. the web 20 of the crosspiece 1,7, saidA handles,- are furnished with stop lugs 26 which engage the outer edge. ofthe flange 18 to limit the swing of said; handles` away from their basal directed position.

The preferred way: of swingably and.A slidably mounting said handles 25 is well shown in Fig. 2 where each handle is shown carried by thev outer end of asleeve 27 slidably and turnably carried by the shaft, 21. A spring 28, coiled around each end portion ofy said shaft,

opposes outward movement ofrtheadjacent sleevev whew ever the adjacent handle 25 is moved outwardlyfar enough to be swung beyond an arcuate lock-ing shoulder 29 (see- `Eig. 2), provided for it in the adjacent, coped out, end portion of the ange i9, said spring therefore functioning yieldably to hold said-'handle in its inswun-g position, there being an arcuate seat 29aV inwardiy of said shoulder, in which saidhandle 25 seats when4 in its inswung position.

As well shown in Fig. 5, the aforesaidv handle members 25 are at times shoulder supportable. in order better to adapt them for thus functioning the aforesaid crosspiece flange 1S. is provided with. a Series. of rectangular cut outs or recesses 31y which are progressively cut Varying depths. into the outer edge of said flange, one series near each side of the barrow frame.. 10. These recesses are sufficiently deep to allow the. handle. form@ ing bars 25 to swing outwardly to a completely/rightangular position, as well as varyingl inclinations therebe? yond, when their lugs 26 Contact the bottom of said recesses, The aforesaid sleeve 23 limits. the sliding movements of the sleeves 27 toward the midwidth of the frame v The already mentioned basal member 13 of the frame carries, in an underlying, attached relation to each end portion of its shelf anges 15, 15a, a mounting plate 35 which swingably carries a conventional castor wheel 36.

Describing in further detail the horizontal basal member 13, the attaching flange 14 is coped out adjacent itsj top edge at each corner to provide for rearwardly bending between the side pieces 11 a flange 3S to co-operate with the shelf flange 15 to provide an enclosure in which to retractedly mount the handA grippable handles 39 and 40.

For the purpose of swingably mounting said handles 3 and 40, widely spaced apart pivot pins 41 and 42 are respectively provided each having one end secured to the ange 38 and the other end secured to the shelf flange 15, so that said pins bridge the space between said flanges. Handle 39 is attached toa sleeve 43 surrounding the pin 41 with a working tit and filling in the vertical distance between the ilange 3S and the flange 15. Handle 40 also is attached to a sleeve 44 but does not completely till inthe vertical distance between the flange 38 and the tlange'lS. The portion of the sleeve 4d between the upper side of the handle 40 and flange 3S is reduced to form a stub sleeve portion 45 in order that when said handle 4t) is extended its entire sleeved portion may be slid upwardly until the top of the stub sleeve portion 45 abuts the under side of the ange 38. When this is done the pair of handles 39 and 40 lie in the same horizontal plane.

A latching means 46 is welded to the attaching flange 14 and extends rearwardly therefrom at a right angle, said latching means having depressions in its upper and lower side edges into which said handles are nested when in their inswung positions, there being sufficient clearance between the sleeves of the handles and the pins on which they are pivotally mounted to provide for a slight rocking so that each handle can override the locking shoulders carried by the outer end of the latch 46 incident to their seating in the aforesaid depressions.

Fig. illustrates the use of two of the barrow frames 10 as a means for enabling two persons conveniently to carry a heavy piece of baggage up a stairway. This baggage is shown interposed between the front sides of two of the barrow frames with cushioned sides of said frames clamped thereagainst by an upper cinch strap 46b and a lower cinch strap 47, the outswung shoulder supportable handle of each barrow being directed outwardly with those in the left hand portion of the view resting upon the shoulders of the person at the rear and the outswung handles of the other barrow grasped by the hands of the foremost of the two persons shown. The frame is shown provided with ripper loops 46a for said strap 4611, and the lower loops 47a for the strap 47.
