6 Claims. 1

The invention relates to devices for holding ice cream cans in fixed relation within refrigeratin cabinets, to facilitate scooping oi the ice -.crea-m therefrom, and it aims to provide a simple, inexpensive and efiective device which may he engaged with the cans and removed therefrom with unusualease. I

Figure 1 of the accompanying drawings is a top plan view showing the device resting upon the upper ends of two cans, in readiness for clamping engagement therewith.

Fig. .2 is a side elevation looking in the direction indicated by the arrow 2 of Fig. 1.

Fig. 3 is an end elevation as indicated .by the arrow 3 of Fig. 1.

Fig. 4 is a bottom plan view.

Fig. -5 is an enlarged detail vertical section on line 55 of Fig. 1 showing the manner of mounting each clamp-operating lever and its eccentric stud.

Fig. 6 is a bottom plan view showing the levermounting disk, its lower hub, and the eccentric stud of said h-u-b.

Fig. 7 .is a fragmentary disassembled perspective view showing one of the sections of the bridge and the associated clamping member in juxtaposition.

A preferred construction has been illustrated in the drawings and will be specifically described, with the understanding, however, that minor variations may be made within the scope of the invention as claimed.

A horizontal bridge 8 .is provided, to extend-between the upper ends of two upwardly open cans 9, said bridge preferably comprising two sli-dably overlapped halves l0 adjustably connected by holt-and-slot-connections ll, permitting the length of said bridge to be varied according .to the distance between the cans 9. The two halves [6 are also spaced apart somewhat :by means of washers 12 in order that the lowermost of these sections will clear the clamping member mounted on the other section, as will hereinafter appear.

The longitudinal edges H of the .bridge 8 are preferably longitudinally concave as shown, said edges being provided with integral downwardly bent flanges M, the outer ends of which are adapted to abut the outer sides of the two can walls. These outer ends of the flanges I4 preferably project beyond the end edges 15 ofthe [bridge 8, and these edges l5 may well be shaped as shown.

Two movable clamping members l6 underlie the end portions of the bridge 8 and are preferably in the form of crescent-shaped plates, each of which is provided with two integral downward- 1y bent fingers [1 adjacent its ends, said fingers being adapted to lie against the inner sides of the can walls. Two hand levers l8 are mounted on the end portions of the bridge 8, and said ledisk being provided -at its outer or vers have eccentric connections with the clampingmcmbers i6, whereby swinging movement of said levers in either direction item the positions slaw/n in the drawings, will move said clamping members it inwardly, thus causing tight clamping of the can walls between the fingers H and the flanges or abutments .14.. It will thus be seen that the device may he quickly and easily engaged with the cans, and disconnected therefrom with equal speed and lease.

The manner of providing the levers 18 with the eccentrics, and mounting said levers, .and connecting their eccentrics with the clamping members L6, isv mostclearly shown .in Figs. 5 and 6, for one end of the device, and the structure .is the same at the other end. From Fig. 5, it will be observed that the plate or bridge section 10 is formed with a relatively large opening 1:9,, which opening is of circular outline. It will also be seen that the underlying clamping member of plate 16 is termed with a comparatively small opening '25 eccentric .to the opening .19, said open- .20 :being also .of circular outline. A disk 12.! contacts with the upper side of plate Ill, said upper side with :a hub 22 and being provided on its inner or lower side with another central hub 23. These two hubs are integral with the disk 21 andare coaxial with i and the lower or inner hub 23 provided with an integral eccentrically positioned stud (24. The hub 23 .is rotatably received in the opening [9 of the plate M], and the stud 24 is similarly received in the opening 2-0 of the plate It. The inner end of the lever l8 rests upon the upper or outer side of the disk 21 and is formed with an opening .25 which tightly receives the outer hub 22, and .a rivet .26 passes through the elements 18, 22, .21, and 24 to secure lever L8 to disk ii. The head 27 of this rivet is large enough to project beyond :the stud 24 at the outer or lower side of the plate I6, holding the latter engaged with said stud .24. It will thus be .seen thatswinging of the lever i=8 causes the hub .23 to rotate in the opening 19, causes rotation of the stud .24 in opening 2.0, and hodily-moves the plate l6 inwardly oroutwardly, according to the direction in which said lever is swung. It will .be noted that the eccentric studs 24 also serve .as pivots for .the clamp plates 16 and hence the fingers .L'! of the latter are permitted to shift slightly with respect to the flanges l4 so that the cans whether of paper or metal will be effectively gripped and held.

In the manufacture of the device, there of course no such conspicuously visible clearance between parts, as that shown in Fig. 5, for illustrat'ive purposes, the various elements being in fact in light contact with each other, wherever clearance is shown in the drawings.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that novel and advantageous provision has been made for attaining the desired end, and while preferences have been disclosed, attention is again invited to the possibility of making variations within the scope of the invention as claimed.

I claim:

1. A clamp for holding spaced ice cream cans comprising a bridge to extend horizontally between the upper ends of two upwardly open cans, said bridge having longitudinal edges provided with integral, downwardly-bent and horizontally spaced flanges to abut the outer sides of the can walls, two horizontal clamping plates contacting slidably and swingably with the lower side of said bridge and disposed at the ends of said bridge respectively, said clamping plates having integral, downwardly-bent and horizontally spaced fingers to lie against the inner sides of the can walls at points adjacent said spaced flanges, two vertically extending circular hubs rotatable in the central portions of the ends of the bridge, eccentric studs on'the lower ends of said hubs and on which the central portions of said plates are pivotally supported, and handle means on the upper ends of said hubs for rotating the latter.
