UNITED' STATES ATENT OFFICE 2,525,002 noon LOOKING MEANS Harvey J. Smith, Greensboro, N. 0.

Application December 22, 1947, Serial No. 793,116

closed in'and covered by my U. S. Letters Patent No. 2,320,159, issued May 25, 1943, No. 2,343,248, issued March 7, 1944, and No. 2,432,455, issued December 9, 1947and that disclosed in my patent No. 2,443,837, issued-June 22, 1949.

The present invention has for its bject to provide an improved cover construction for the can stacks and a simplified locking mechanism-for the same and for the door which-closes the can and tool entrances on the front wall.

To the attainment of the aforesaid objects and ends invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully. de-. scribed in the following detailed description, and then .be particularly pointed out in the appended claims, referencebeing had to the accompanying drawing in which: V

Fig. 1 is a side elevational view of my improved rack, looking from left to right in Fig. 2.

Fig. 2 is a front elevation of the same.

Fig. 3 is a detail horizontal section on an'enlarged scale, taken on the line 3--3 of Fig. 2.

Fig. 4 is a detail elevation of the cam disc, a portion of one of the locking levers being indicated in dot and dash lines to show its relation to the cam disc in the locked position.

7 Fig.5 is an enlarged detail vertical section on the line 5-5 of Fig. 2. l

Fig. 6 is anenlarged detail horizontal section on the line 66 of Fig. 2.

In the drawings in which like numeral-sand letter of, reference indicate-like parts in all the figures, I is the base, 2 the front wall, 3 the back bent back as at 2 to clamp over the sides 1 of My invention relates to racks of the kind dis- 1 4 Claims. (Cl. 312-193) said but differ from the samein that the closures 6 are formed of sheet metal and are provided with in the wall portions 2* and hook over the wall portions at the lower ends of the slots 5. The

top ends of the covers 6 are closed as at 6 the tops 6 inclining downwardly outwardly from beneath the top 3-! t drain rain water.

At both top and bottom the covers are provided with rubber bumpers I0 approximately U-shape in plan View, the bumpers having heels Ill to fit over the folded back edges 6, see Fig. 6. To put a cover in place one sets thedogs 8 into the slots l and lifts the cover until hooks 9 pass intoslots 5. The cover is then let down until it is supported by the hooks in a position to be locked as will later fully appear.

the side walls 4. Each wall 4 is preferably formed of a single piece of sheet metal, the sides 4 of which project outwardly at right angles to the wall proper. The metal is further bent over and back on itself at intervals to form the intermediate partition 4 between which projections 4 4 cans may be stacked. The back wall plate 3 is bent similarly to the front wall plate 2 to provide corresponding portions 3*, 3 and 3.

The front, side and back walls, base and top when assembled are formed into a rigid structure in any suitable way as by spot welding, for example.

The closures or covers for the can racks are similar to those disclosed in my application afore- The can passing opening I l and the tool passing opening i2 are closable by a single door 13 hinged at l 4 and provided with a releasable sprin latch l5 of known construction. The door l3 also has a knob It on its front, while latch I5 is mounted on the back face of the door I3.. 011 the back of the door and in line with opening [2 are locking bar element receiving straps I! between'which and the door a foot 35 of locking levers 35 may enter, 7

Below opening 12 'is a can collecting receptacle 7 passing. opening I8 which, is closableby a door [9 whose upper end is deeply channelled as at 20 (Fig. 5) and whose lower end is provided with a shallow channel 2|. A handle 22 is provided on the front or outer face of the door l9 and a locking bar guide 23 is secured to the back or inner face of the door.

A wall portion 2 has a slot 36 in line with the guide 23 to permit passing a locking bar 24 into the guide 23 with its ends extended beyond the sides of the door (Figs. 2 and 5.) The bar 24 has an end piece 25 that liesat right angles to the plane of the bar and acts as a stop.

The locking mechanism for the two side covers 6 and thedoor I3 include a locking knob 26 tumably mounted on the front wall 2 by a mounting base 2'! held in place by a washer 28and nut 29. The locking knob 26 has a squared shank 30 on which fits the cam disc 3|, a squared opening 32 being provided for the purpose. The disc 3| has two eccentric slots 32, of which the

ends

32 and 32 however, are concentric with the disc and with one another.

Locking levers 35 are pivoted on lugs 34 secured to the back of the front wall 2, and are provided with cross bars at their ends. Each cross bar includes a locking portion 35 and a portion 35 The portion 35 at the upper end of the locking bar carried a stud 35 which rides in a slot 32 in the cam 3| as best indicated in Figs. 2 and 4.

When lock 26 is unlocked by the usual key and turned counterclockwise levers 35 will be moved to withdraw upper portion 35 from engagement with the tops of latch hooks 9 and will withdraw lower portions 35 from engagement with the door straps H to release the covers 6 and door 13. To lock the covers 6 and door [3 closed knob 26 is turned in a clockwise direction to force the upper ends of lever 35 into holding engagement with hooks 9 and into loops 23. Relocking knob 26 by the key will in turn lock covers 6 and door; I3 as will be clear to those skilled in the art.

It will be seen by reference to Figs. 2 and 4 that the axes of the studs 35 lie in a horizontal plane that is located above the axis of the cam disc 3| so that when the cam disc is in the fully locked position the studs 35 will lie in the concentric ends 32' ofthe slots 32.

33 indicates cotter pins used to hold parts in place. 38 indicates the can chute, 39 a can retarding spring, 40 a can deflector, M an oil drip receiver, 42 a tool shelf and 43 a can collecting receptacle, all of which parts 38 to 43 inclusive are of known construction and are not claimed hereinbut see my patents aforesaid. g

From the foregoing description, taken in connection withthe accompanying drawings, it is thought that the construction,,operation and advantages of the invention will readily appear to those skilled in the art.

2. In apparatus of the class described, a chambered body having side walls that are each provided with a set of stacked-can-receiving recesses and having a second Wall that is provided with a can-receiving opening, a door for closing said opening, covers for covering said recesses, looking bars pivoted to said second wall, said looking bars having rigid means to cooperatively engage said door and said covers to hold them in place, and a cam-carrying locking knob mounted on said second wall and being operatively connected to said locking bars.

3. In apparatus of the class described, a chambered body having side walls that are each provided with a set of stacked-can-receiving recesses and having a second wall that is provided with a can-receiving opening, a door for closing said opening, covers for covering said recesses, locking bars pivoted to said second wall, said looking bars having rigid means to cooperatively engage said door and said covers to hold them in place, and a cam-carrying locking knob mounted on said second wall and being operatively connected to said locking bars, the cam of said camcarrying locking knob having eccentric slots with concentric ends and said locking bars having studs engaging in said slots.

4. In apparatus of the class described, a charmbered body having side walls each provided with a set of can'stacking recesses, and a cover for each set, said covers being of approximately U- shape in cross section and having locking dogs at their bottom ends, said chambered body having openings to receive said dogs, locking hooks secured to the sides of said cover at a suitable locatiton above said dogs, said chambered bodyhaving slots to receive said hooks, and hold said cover in place, and means cooperating with said hooks for locking said cover in place, said means including locking bars pivoted to said chambered body and having rigid feet to engage said hooks, and means to rock said locking bar on its pivot from one position to another.
