"This invention relates to can flattening tools and machines, and in particular a manually actuated can flattening device having a manually actuated: lever pivotally mounted at one side of a'crushing table with cutting means for removing the ends of the can whereby, with the ends removed','the cans are placed upon the tableand flattened,.or crushed by the lever.

The purpose of this invention is to provide means for flattening cans to facilitate disposal of cans particularly as used as containers for various types of products. In'the conventional type of can in which numerous types of household products are provided and which also are used for paints, oils or other products, it is difficult to dispose of the can Land where cans are buried or sold asjunk it is desirable to flatten the cans. In crushing or flattening cans it has been found that with the heads or ends removed the cylindrical body of the cannot only flattens more readily but occupies comparatively smaller space when flattened. With this thought in mind this invention contemplates a can flattening machine including means for first. removing the ends from the cans and then means for crushing or flattening the body of the can whereby the final product occupies comparatively The object of this invention is, therefore, to provide a can flattening tool in which an operator may first remove the ends from the can and then,

remaining in substantially the same position, flatten the body of the can. l v

Another object of the invention is to provide a can flattening device that may be used for cans of different sizes. 7 A further object of the invention. is to provide a can flattening'machine which is of a comparatively simple and economical construction.

With theseand other objects and advantages ally mounted on a base with a flattening table carried by the turntable, a lever pivotally mounted 3 at the upper end of the flattening table and positioned to crush objects on the flattening table,

a knife carried by the turntable and positioned on the opposite side of the pivotal mounting of the lever and a block carried by the lever for forcing cans over the knife.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view showing the can flattening tool.

Figure 2 is an end elevational view of the tool inview the invention embodies a turntable pivot- 5 Claims. (01. 153-405) looking toward the knife for removing ends'from the can.

Figure 5 is a sectional plan part of the can flattening tool showing thecircular knife and flattening table in section. Figure 6 is a cross section taken on of Figure 4 showing the manually actuated lever. with the can forcing block onone side thereof.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved can flattening tool of this invention includes a turntable l0 pivotally mounted by a I2 with a flattening table 13 lik 0 pin II on a base carried by the turntable, a circular cutter carried by the turntable andag hand leverl5 pivotally mounted by a hinge 16 on the flattening table and having a block I! with a sloping face I8 mounted on one side and positioned to coact with the cutter M for removing ends from cans,

and in which the sloping face [8 1 :arovidesmeans for compensating for-can of different heights.

The turntable I!) is formed of a substantially; flat panel and the lower surfacether'eofis -spaced from the upper surface of thebase I2 by a spacing washer IS. The pin I I extends upwardly through" the base [2, and the washer l9 and through an Iii. As illustratedin opening 20 in the turntable v Figure 4 the pin H is provided with a head 2| that is positioned ina recess 22 in the under surface of the base l2.

The circular cutter I4 is provided with a beveled. upper outting edge 23*and a slot 24 is provided atone side so that the entire end is not cut from I the can. This provides a hinge whereby, the end,

may be bent into the can so that the cans maybe folded with the ends on the inside thereon The cutter I4 is mounted upon a panel 25. and the:

panel is mounted on the turntable Ill by

pins

26, and 21 which provide means for readilyremoving the cutter so that cutters of different sizes may be used to accommodate cans of different diameters.

The cutter I4 will cut ends of cans within the average range of sizes however for comparatively small cans and also for comparatively large cans it is desirable to use small or large cutters :0 correspond with the size of the can being fiatened.

through the lower.

line 6-56 The lever I5 is provided with the block 11 and with the face of the block inclined cans of different lengths may be cut as the can may be ripped at different points along the face l8 of the block.

The hand lever l 5 is hinged to the base or flattening table structure by the hinge I6, one plate, 28 of which is positioned between the rear wall 29 of the flattening table and an upright panel 30 of the: turntable whereby the hingeisrigidly held, and'the upper plate of the hinge which is indicated by the numeral 3| is secured to the lever l5, by welding or other suitable means.

With the parts arranged in this manner the can, as indicated by the dotted line 32 is first positioned upon the cutter l4 and hydra-wing the lever l5 downwardly theblock |1-forces the can over the cutter substantially removing one end. The inclination of the sloping face lii'wil'l' raise the extreme lower portions of the lever during the cutting operations, so that the lever I 5 will not strike the support for the base of the de--- vice when the device isacting. on cans of small height. Thepositiorp of the can is then reversed and the operation repeatedwhereby the opposite endiof the: can. iST substantially removed. The

ends "are folded into the canf and. the can placed in the positionshown in: Fig; 41' wherebydownlward movement of the levenflattens the can againstthe' table -I 31 It willl be understood; that-the tool may be provided with cutters of different sizes. and dif-- ferent 'sizes 'of tool'smay'be: provided for different types ofcansa- Itwillal'so be understood that the position of the hinge may be adjusted: in relation to" thebase" to compensate for 1 extra'larget or smallencans;
