Similar reference characters refer to similar parts throughout the several views of the drawmgs.

For purposes of illustration there is shown in the drawings a carrier adapted to carry two ice cream cans C and simultaneously. This carrierincludes a platform or base plate 10 to which is secured at its center the lower end of a lifting standard which is telescopically adjustable in height and extends upwardly therefrom higher than the cans C and C. This lifting standard includes a lower rod 1 which is secured to and extends upwardly from the base plate 16. On the upper end of rod 1 is slidably telescoped a tube ll having a spring latch finger Ila at its lower end biased toward and adapted to be re-' ceived in any one of a number of notches la provided in the rod 1 to receive the latch finger I la and hold the tube l l against sliding upwardly .or downwardly on the rod I. Thus the overall height of the lifting standard may be adjusted to accommodate cans or other containers of different heights. To the upper end of the tube H is secured a suitable carrying handle l2, as by being threaded thereon, as at i3, or otherwise secured thereto.

Portions of the base plate [0, on opposite sides of the lifting rod I, form laterally projecting container supporting ledges l4" upon which at least a portion of the bottom surface of a container or other article may rest; and the upper surface of each supporting ledge portion 14" is formed with an arcuate groove l4 shaped and positioned to receive therein a portion of the bottom flange l of an ice cream can, such as C and C, so that when these flanges of the cans are seated in these grooves the cans are supported on the platform in and are prevented from sliding off of the platform. Each of these grooves I4 is defined at its rear by an arcuate flange l4 extending upwardly from the platform and at its front by the ledge portion M" being thickened.

An ice cream can gripping device is slidably carried on the tube ll of the lifting standard, and includes a sleeve l6 slidably surrounding the tube II and having at its upper portion a pair 4 of arms I! diametrically extending therefrom and terminating in the cylinders 18 extending substantially parallel with the axis of the tube [6 so as to overlie the supporting ledge portions I4". Each of these cylinders supports and guides a spring pressed plunger l9 having on its lower end, exterior'of the cylinders i8, an article gripping element 2|] in the form of a disc 23 having its undersurface roughened to provide anti-slip teeth 21. The lower ends of the plungers 19, carrying the gripping members 20, are normally urged downwardly by compression springs 22- disposed within the confines of the cylinders 18 and between the hub 23 of the gripping element 20 and a plug 24 which is fitted into the top of the cylinder I8. The plug 24 has a central aperture through which the upper end of the plunger i9 extends and whereby the plunger is centered and guided in the cylinder; and a stop-nut 25 may be threaded on the upper end of plunger 19 to limit its downward movement.

The gripping device (i. e., parts I6, ll, 18 and 20) is urged to slide upwardly on the tube H of the lifting standard by means of a compression spring 26 within the sleeve i5 and encircling the tube H and having its lower end bearing against a stop abutment 2T fixed to the tube H, as by screws 28, and its upper end against an abutment sleeve 29 slidably encircling the tube H and bearing upwardly against a plate 30 of a latching mechanism. Thus, it will be seen that when one or two containers, container C and/or container C, are positioned on the ledge I l" the gripping device will overlie an opposite portion of the containers and may be pressed downward, against the tension of the spring 26, to bring the gripping elements 20 in contact with the upper surface of the containers to bind the containers between the ledge l4" and the overlying gripping member 20. The gripping device will be held in its depressed position by the latching mechanism now to be described.

The latching mechanism is mounted in an upper extension 39 of the sleeve it which has two opposite side wall portions cut away, as at 3 8, to house and accommodate friction latch plates 30 and 35. The latch plate 30 rests upon the bottom of the passage 38 and has one end 3| received in a slot formed by an overlying bridge portion 32 integral with the sleeve 16. This end 3| of the plate 30 is termed a. heel portion as the plate fulcrums on this end of the plate in the operation of the latch; the plate 30 having an aperture therein through which the tube Ii extends. Opposite the heel portion 3! of the plate 30, is an upwardly extending lip 33 upon which rests a heel portion 34 of a tiltable friction clamping plate 35 overlying the plate 30. The plate 35 has a central aperture 36 through which the tube il extends and the plate 35 is provided with a finger piece 31 on its end portion opposite its heel portion 34 and extending laterally beyond the extension 39. The aperture in the plate 35 is larger than the aperture in the plate 30 and permits a greater tilting movement of the plate 35 to move the edges of the aperture 36 into clamping engagement with the surface of the tube II, when pressure is placed upon the plate 30 by the spring 26-through its abutment tube 29. To hold the plates 30 and 35 in position, a flanged plug 40, apertured'to have the tube ll slidably pass therethrough, closes the top of extension 39 of the sleeve 16 and may be held in place by any suitable means, such as by screws, threads or the like (not shown). It

Thus, the arms-50 serve as means auxiliaryto the gripping elements 2-0 to hold zthe canspnthe carrier against, inadvertent and accidental,displacement therefrom even in the v t; ha he rip in nga e i ha f ping element has not been: brought intorfirm enough engagement witha ganto prevent the can from slipping-thereunder.

When the cans have-beenreleased from the g'carrier thetgrippingidevicethas been moved automatically .by the .action of nspring 2.6 .ainto its uppermost positioni.on-the; standard and consequently the carrier, when unloaded, normally will be in condition to be loaded with cans. To load the carrier the bottom flanges of the cans are seated in the grooves I4 of the platform l0 so that the cans will stand close to the lifting standard, and the height of the standard adjusted to the proper height for the cans. The operator then, by pushing down on the finger piece M of the gripping device pushes the gripping device down on the lifting standard against the tension of the spring 26 until the gripping elements 20 have been pushed into tight gripping engagement with the tops of the cans. The operator then removes his hand from the finger piece 4| and the gripping device will remain in tight gripping engagement with the can, being automatically held against upward movement on the lifting standard by the transom latch which includes the plates 30 and 35. The attempt by spring 26 to force the gripping device to move upwardly on the lifting standard wedges the edge of the plate where the tube H of the standard passes therethrough so tightly against the tube II as to prevent upward movement of the plate 35 on the tube II and consequently prevents movement of the gripping device upwardly on the tube H. The user may then conveniently lift and carry the cans from place to place by means of the handle l2 which has been provided for the purpose. Incidentally, the nut part 60 of the handle and whereby it is secured to the topof the -tube lil :may ,serve as :a stop abutment for the gripping :device -iwhen-zmoved upwardly on -the" tube 1 l by the spring. When it is desired tounload thegcarrier the operator need merely place :his finger underneath the finger portion 31- of the locking plate 3 5 and ;tilt theiplatedS toward horizontal-position, sByethis movement of locking plate 35 v the :plate becomes "comprisingmelatively few parts ,and is mostieasy and convenient to operate and to use. .Alsozas stated hereinbefore our invention is ..not limited tea-carrier suited *for use only with two :cans or other-containers; but the carrier maybe fashioned'lto'accommodate asingle can or container or toaaccommodatemore than two cans ori constandard secured to extend upwardly 1 from the -platform and having-a handleat its upperlend whereby the car riermay be transported misus- -pended position, a container gripping device slidably mounted on the standard and adapted =to "be manually --mov'ed toward the platform :into
