CAN OPENER.

Applicatieniled January 22, 1927. Serial No. 162,914.

"My invention relatesto improvements-in can openers'be1ng more particularly concerned with the provision of a can opener A'suitable for use in hotels, factories, ctc. v yl1ere it is d esired toopen' a great many cansex-v peditiouslyand with a minimum'elort.

One ofthe objects of my invention is the provision of vsuoli a canv opener capable of Iholding and severing the tops of cans of val rions sizes with a minimum of physical effort.

Another object of my invention is the provision of such a. can opener having means to gauge the height o-f any can within the usual range of sizes to'adjust the cuttmg element at proper height 'for said can, and-means to move the cutting Aelement into and out of operating position for opening a plurality of cans of `the same size without changing vsaid adjustment.

AAnother object of my invention is theprovision of'such a can opener having' means for holding such a movable cutting element in operating posit-ion and' means to hold the same in proper position for the insertion of a can y Other objects and advantages of my invention will appear more fully from the following description and from the accompanying drawings in which similar characters of reference indicate .similar parts throughout-the several views..

. View of my canopener showing a canin po' 4 0 opener;

vIn thedrawin'gs Fig-1 a side elevational i Vlegs 11 and an'upWardIy extending rearward Jflange y12 for. a purposeful-ther to be' exf plained., The base- 10 ,is preferably constructed of cast iron and may beef anyshape or conformation .other than that shown in' the planfviewbut the 'shape shown provides' 'sutiicient flat upper surface to accomplishthe purposes of the yinvention without unduly increasing its' size and weight.

The base 10 is preferably yprovided with a slot 13 extending inward from one side of the base and having substantially parallel edges 1 4 to form a guide. The base 10 is also provided With an aperture 15 of substantially the 6o same length a's the slot 13 and having parallel edges 1'6. The aperture 15 is preferablyprovldeeb'with anenlarged portion 17 at its inner end for the purpose of permitting the-insertion of the' slider 18 further'to be described. 65

The baselO is provided with a downwardly extending lug 19 having a bore 20which isV adapted to journal a shaft 21 which is pro-. vided with aleft-hand threaded portion 22 J and the right-hand threaded portion 23. The 79 shaft 21"1s preferably provided with. a I'educed end thereby providing 'an annular shoulder 24 which serves as ja thrust bearing against the lug 19 and the shaft 21 is alsov provided with a crank 2 5 havinga sleeve26, 75 which may be keyed or pinned to the shaft 2l-as at 27 and which isv adapted to rotate the shaft21 byfmeans of the 'handle 28. The' i shaft 21 is provided with a slider 18' having an aperture 30 provided with complementary right-handed'thre'ads, and having a pair of horizontally projecting lugs 31 and 32 which areadapted to slide upon the' lower surface 'of thebase 10 when the shaft 21 is journaled in the lug 19. The slider 18'is alsoprovidedwith an upwardly extending lug 33 projecting through the aperture 15 in the base and extending above said base. The lug 33 lis .pro-

vided with a clampingshoe v34 comprising a cast metal member having a substantially flat 99 lower surface, and a vpair of diagonally pro-v v jecting'anms35and 36 having-a side surfacev 39. The shoe34'may be' ixedly supported upon the lug 33 by a screw bolt 40.

The shaft 21 is'also provided at its right-Iv 9.5 'i

handthreaded portion 23 withya'second ider 41 having a similar `threaded'. aperture 42 with complementary right-hand. threads,-

With similar horizontal projecting shoulders to-slde on the lower surface of thebase 10,

an upwardlyprojectin lug 44 extending through theslot 13 an supporting-by, the

screw bolt 45 the clampingshoe46. The shoe 46 may be of similar construction tothe 105 shoe 34 having diagonally projecting arms 35 and- 36 with a serrated side surface 39.

The method of assembly of the foregoing 'partis as follows:

The slider may be threaded-.upon @ell-10g bther end of the shaft 21. Both sliders should posed serrated surfaces 09, it will be obvious preferably be somewhere near the inner limit of their ranve of movement upon the threaded portions 22 and 23 and the slider 18 should be so located that when the upper end of the slider is ipassed bodily through the aperture 18 the end 0f the shaft 21 may clear the inner` side of the lug 19 for insertion into the journal 20. The crank 25 may then be permanently attached to the shaft 21 and the shoes 34 and 46 ixed to the lugs 33 and 44. It'will thus be observed that the shaft is not only supported by the journal 20, but the lower surface of the shoe 46 sliding on Ythe base 1() supports the other end of the shaft 21, while the projecting lugs 43 and 32upon the sliders cooperate with the opposed surface of the shoes 34 and 46 toretain the sliders within the guides formed by theedjacent edges of the base 10. As the shoes 34 and 46 are provided with the diagonally disthat rotation of the crank 25 by means of the handle 28 may cause'the shoes 34 and 46 to move toward each other to clamp the base of a can Vof any of the usual sizes, or to move away from each other to release the same.

In order to reenforce the base 10 it may be A provided with a plurality of rearwardly eX- tending reenforcing flanges 47 and a pair of transverse reenforcing Hanges 48 along the sides of the slot 13 and aperture 15. 'Y The base may also be provided Awith a plurality of countersunk holes 49 for the insertion of screws to fasten the same to a table or work bench. Y

The base 10 may support by means of the lug 11 and flange 12 an upright standard 50, which may consist of a substantially rectangular plate of metal, preferably steel .having a substantiallySrectangular slot 51 eut in each edge. The standard 'may be attached to thebase by means of a plurality `of screw bolts 52 and it may also be provided with a plurality 'f counter-sunk apertures 53 .Y for the purpose of Vfixing `the same to a ver.-

tical Wall 54 by screws 55 when so desired.

The standard 5 0 supports for sliding movement a plurality of sliders 56 comprisingsub-f sta-ntially Hat members of angle iron having inwardly turned flanges 57 which are adapt- 'ed to be lreceived in the grooves 5 1 to slide therein. The sliders 56 are each provided with a pair of apertures 58 to receive the parallel bolts 59 and 60. The bolts 59 and 60 are turned down at their ends as at 61 to provide annularV shoulders 62 against which the sliders 56 may be clamped by thel nut 63 to hold ther same in fixed relation without bind-A ing in the slots 5l. The bolt '60 supports for 'pivotal movement a lever 64' havinga down: ward and rearwardly projecting legl 6 5, a

horizontal leg 66,'a verticalbore 67, a goose neck 68, andfapair ofrhorizvontal bones69 and`70 for a-purpose further to be described.

lThe leg 65 may be provided with a bore 71 adapted to receive the bolt 60v and a projectgear 74 may be provided with the usual ani' nular boss 77 on its lower side and the boss 77 supports by means of the screw bolts 78 and 7 9, a guide plate 8O which may be of substantially square metal plate having a rectangular groove 81 in its'upper surface and'-l a pair of counter-boredapertures to receive the Screw bolts 78 'and 79 with their heads.

The guide plate 80 is also provided with al .central aperture 82 counter-bored within the groove`81 and which is adapted to receive the screw bolt 83 with itsr countersunk head. screw bolt 83 is ground to a conical pointand in order to support the saine firmly inl the guide plate 8() and to cover the screw bolts The 78 and 79 a washer-85 may be passed over the point 84 and a nut 86 screwed thereon'to firmly clamp the screw bolt 83l in the guide plate 80 andto'retain the said washer in place.

The guideV plate 80 is adapted to receive a substantially rectangular bar 87 in the,

groove 81 for sliding movement and in order to fix the bar 87 in any adjusted position a set screwv 88A may be threaded in the guide plate 80. The bar or cutting arm 87 may be f provided at one end with an aperture 89 which is adapted to receive a bolt 90 to clamp lun the flange 91 of a cutter 92. Inorder to sup-` Y port the cutter' 92 fixedly Without pivot-al stirrup 93adapted to closely tit the arm 87 on both sides and to receive the bolt 90 through its yoke. By makingthe cutter flange 91 of substantially the same'width as the arm 87 the cutter is adapted to be 'clamped between the stirrup 93 'and the bar 87 by the bolt 90 and isfirmly held against the pivotal movement by the upwardly projecting legs of 'the -U-shaped stirrup 93. The cutter 92 is preferably of substantially triangular shape as shown in Fig. 3 ,with a sharp upwardly slopl movement I provide a substantially U-shapcd ingeutting edge on each side so that it is adapted to pierce the top of the can by its.

point and ,to cut the top of the can by being moved -in the direction of either cutting edge,

.the slope of the cutting edge aiding the cutter in making av slashing cut. The point 84and cutter 92 are preferably made of the vbest tool steel so that Ithe piercing and cutting parts may withstand long and continuous service. It will thus be observed that by the means of the set screw 88 and the sliding bar 87 my cutter may be .adjusted to sever the top of any ordinary sized can or to cut out the to as closely to the side walls of the cam as is esirable..

In order to actuatethe Ibevel gear7 4 and the cutter 92 I'provide a horizontal shaft 9 4 whichpmay be journaled in the bores 69 and and the shaft 94 supports 'a second bevel gear which is keyed or splinedto move with said shaft. The shaft 94 may be actuated by a crank96 which has a sleeve 97 kyed or pinned to the shaft 94 and a handle 9 The shaft 94 is retained within its journals by means of the bevel gear 95 which is pinned to thel shaft as at 99.

In orderto more easily move my cutting mechanism into and out of the operating position, I provide a second lever 100 having a substantially straight lower portion 101 and an upwardly benthandle 102 which may extend over the goose neck 68. The lever has a bore 103 which is adapted to receive the bolt 59 by which thelever is pivotally supported and the horizontal portion 101 is pivotallyconnected to the leg 66 of lthe cutter supporting lever bv means of a link 104 and a plurality of bolts 105 and 106.- The arrangement and shape of the legs 65 and 66 of the lower lever and the portion 101 of the upper lever should preferably be such that when the cutter arm 87 is in horizontal position the centers of thel bolts 59, and 106 are in substantial alignment, the links 101 and104 forming a toggle which substantially locks the levers in position where upt ward force upon the cutter 92cannot change the position of this linkage.

In order to limit the downward movement of the lever 100 the link 104 may be provided with substantially U-shaped ends, the yoke 107 providing a limiting stop against which the lever 100 may bear to limit its downward movement. It will thus be observed that when the linkage is in full line position shown in Fig. 4 the rtoggle cannot be broken by pushing upward upon the handle 98 or other parts connected with the lower lever 64 butby pulling upward upon the handle 102 of thelever 100 the toggle will be broken, the pivot bolt 105 passing upward out of alignment and the link 104 pulling the lever 64 together with itsassociated mechanism and cutter upward out of contact with the cam. The relative positions of the toggle levers are then shown in the dotted lines- )f 4. If desired the stop 107 may be so arranged that the-center of the bolt. 105 will be slightly below the line of centers of the bolts. 59 and 106 thereby setting the toggle past dead center but it is suiiicient to have these centers in line so that the toggle is on dead center.

In order to support the sliders 56 in Xed relation upon' the standard 50 the bolt 59 may also pivotally support a cam 108 having a surface increasing in radius below the bolt` 59 as at 109 and having a projecting'bolt 110 for manual actuation. It will thus be.'v

observed that if the bolt 110 is pushed downwardly the increasing radius of the cam .108

ard 50 land cause the angese? to bind in 'their grooves as well as to clamp the part .ofthe upright 50 between the cam 108 and K the flange 57. The weight of the bolt 110 y and the slider 56 in a Aplurality of different' positions. The plate 11.2 is provided with a forwardly projecting arm 111 which performs the function of a gauge.l

The operation of my can openeris as follows:

` The gauge 111 lshould `preferably be setA by means of the nuts 114 at such position that the cutter 92 will project below the gauge a sufficient distance to penetrate well into the top of the can 114. This adjustment is a permanent one and need not be changed until the cutter has been considerably worn down by resharpening or otherwise. The 'cutting mechanism should first be moved to'its uppermost position by means of lifting the handle 102 to the linkage position shown in'Fig. 4. The shoes 34 and 46 may be moved to their outermost position by yrotating thecrank 25 in a counter-clockwise direction, the sliders 18 and 41 progressing outward upon the left and right hand screws 22 and 23. A can may then be placed upon the base 10 and slid backward to the position shown in 'dotted lines at 116 in Fig. 2 underneath the gauge 111. By releasing the bolt 110 the slider 56 bearing the entire cutting mechanism may be moved upwardor downward and adjusted to such position that the gauge 111 rests upon' the upper edge 117 of the camand the slider 56 may be clampedl in such position.

The can may then be placed between the in a clockwise direction, the jaws will be acwill'cause the cam to bear against the standthe cam 109 by means of 'jaws 34 and 46 and by rotating the crank 25 tuated by the left and right-hand screws 22 and 23 toward eachother to such distance as is necessary to clamp the base ofthe can between them,.the serrated surfaces 39 serving to effectively prevent rotative movement o fthe can. It should be noted that the relative positions ofthe vjaws 46 should be Isuch that when any can is clamped between them the can is accurately centered beneath the point 84 in the axis of the shaft 73:l For this purpose'it is suiiicient that the ysurfaces 39 be' By pulling forward andv downward on the 5 lever. 102 the mechanism can be brdught into the position shown in lFig. 1, the point '84 penetrating the center of the top ot' the can and the'cutter A92 penetrating the top of the can adjacent theouter wall of the same. The

1f*- adjustment of the slider 56 and the cutting arm 87 having been once made, a plurality of cans of the same size may have their tops re! moved and by simply clamping the 'can upon the base, piercing its top as just described, and

l5 rotating the crank 96 through a sufficientarc to causethe cutterto make one revolution.' The sloping edge of the cutter 92-Will then follow the inside'of 'the Wall ofthe can 115 A'severing the top therefrom while the point 84 will hold the top in proper position until the' top is completely severed. The handle 102 may then be lifted the can' unclamped' and removed, the cover removed from the point 84 and a second can put in place 'for the same operation.v Y Referring to Fig. 5 I have here" shown-a modified form of linkage in which the bolts 59 and 106 are connected bg a coil spring 118 thereby tensioning these parts toward each 3f other so that when the toggle formed" by the links 101 and 104* is in the position shown the spring positivelvpresses the link 104 against .a

-means for adjusting said gauge.l L

the leg 65, thereby providinga :more positivemeans of locking the.sarne. The spring also' '3? performs an additionall function when the linkage is in the dotted line position shown'in-V Fig.'4 since it may made of sufficient strength to support themechanisin' in the upper position without physical effort; 'It 40 vwill thus be observed that I'have'iiivented a can opener which is capable of efficiently and expeditiouslyseveri'ng the tops of cans of many diiferen'tisizes and which includes means for gauging the height of any can and setting the cutting 'mechanism'accordingly s o that'the cutter may be easily moved into and out ,of operating position without changing While I have illustratedand described the specific .form of myjinvention, many changes may be inadewithout departing,l ,from the Y spirit of the invention. and I do not wish to be limited to the precise details of construction ,setforthbut desire to avail myself of all' 5: changes within the scope of 'the appended claims. i Y
