Specification of Letters Patent.

Patented Sept. '15, 1914.

Application filed October 8, 1909. .pSerial No. 521,766.

To all w/zom 4it may concern: l

lie it known that I, Josi-nii F. MoiiAN, a

citizen-of the United States,- residing at.,

Park Ridge, in the count)7 of Bergen and State of New Jersey, have invented certain new and useful Improvements in Can-Open ing Machines, of which thelfollowing is a specification.

This invention relates to iml'irove'ments in can opening machines and the obiect of my A invention is to provide a simple, inexpensive.

and highly efficient device arranged'toxcut the head of a can at onestroke of a lever.

The mechanism for carrying ont my invention comprises a can holder, a knife carrier in which the knife 'is at. all times heldy and concealed so .as not to injui'e'tlie hands of a user adjusting a can therebeneatli, means for adjusting the can, means for causing the knife to penetrate thel can as -it' makes its cycle, and means for actuating the knife as the level' is moved in a vertical pla-ne. l

Yith the above and other objects in view my invention consists inthe combination, arrangement, and details of construction shown in the .accompanying drawings and then more particularlypointed out in 'the appended claims. Similar reference characters designate similar parts throughout the respective views, whei'ein- Figure 1 isa side elevation `of my invention Fier. 2- is a cross-sectional view vof the knife. depressing mechanism t0 be described,

" shown in detail, Fig. is an exaggerated top planof'the can table, Fig. 4 is a cross sectional view`of the table and adjusting means therefor, Fig. 5 is a fragmental detail view partly in section of the rotary screw for actuating the can cutter, Fig. 6 is a fragmental detail view of: the knife depressing mechanism showing the knife depressed`to engage a can, Fig. 7 is a detail view inperspective of the screw cylinder and loose shaft engaged thereby and, Fig. S is a top plan view of the screw mechanism and frame therefor. .f l l YReference being made to the drawings which are merely illustrative of my vinvention', 1 designates a suitable frame fastened to a suitable support, said frame formed witlntlie `outwardly-extciidingarms 2. 3 and 4 respectively designed to support the parts of my device. Fulcruiiied upon a pivot 4 fixed upon the arm 4 is a lever 18' having a handle 1S, said lever being movably connected to the vertical shaft 16 so as to rotatably lift and depress the saine vvertically, by any suitable means, such as the radius link l? pivoted to lever 18and to a block 27 in which may swivel shaft 16.' The arm 2 is formed lwith a bifurcatedportion 5, the free end of each offset of which 'is formed with a sleeve through which passes a vertical screw 6 upon which screws a hand wheel' 7 disposed between the offsets of the arm 5, the screw 6 being of suflioient length can holding table. Said table is composed ofa bottom or base 8 secured rigidly to the screw 6 and moving therewith, and mounted' upon said base are the Yopositely-arranged rack bars 9, and 10 witi which the p'awl members 11 are arranged to have engagement, each pawl member being secured upon a cam member 13" which cams are disposed at diametrically opposite points andare arranged to ride against studs 13 formed underneath dogs 12 and mounted `upon the rectangular lguiding blocks' 42 by any suitable means The dogs 12 are of arranged to slide over the top 44 of the table which is spaced from and suitably secured to the fioor or base S by any suitable means such as posts 45. The forward end of each dog is formed with a can engaging part 46.

The cam members 13 carry their pawls at 'their ends, and are integrallyor otherwise formed upon the' inwardly or horizontally disposed iange 12 formed upon a ring 8 formed upon the base 8 upon which the flange 12 rests, said flange being held against displacement by thev top 44 of the be seen that when lthe blocks 42 are disposed centrally of said openings, the cam members the pawls carried by said cam members will engage said racks also. The cam surfaces are so formed that when the wheel handle 15 formed aroundthe ring 8 is revolved to move the cams the st uds will simultaneously move toward or"froin the axis of the screw 6.

to allow for the vertical adjustment of the.

- working in elongated openings 43 formed in alineinent upon the top of the table,saidv blocks being integial with said dogs arid-l held against displacement in said openingsgreater width than said openings and are embracing in sliding relation the ring 47V table. Reference being had to Fig. 3 it willk will engage the studs at central points and 11o il verse hars 20 which at their ends are rig-l idlyeonnected hy the bolts Said posts andhars form a. frame `which rests upon the cam head 3S and is held rigidly in upright position, so that the 'pin 2i may at all times fit the spiral grooves 25, by means or' the tie holt nearest the frame l which passes through the enlargement 49 formed upon arm which :s arranged to supymrt the horizon l cam head the usual nuts heiug interposed so as. to properly position said tie holts.

Formed miitraliy in the. screw-cylinder ZG earn her-.d 28. Said shalt 5i is polysided to i Correspond to the shape of the channel int-o which it lits so as to he rotated in unison with the screw' oylinder, and it is formed with a cylindrieal part projecting 'fentrally through the .cani head :2S and carrying;A spaced apart tin `from the knife carrier :H- at its bottom. The cam way 25) is Formed onthe peripl'ieryof the member QS preterahly less than a quarter oi its iene-th and the edge ol. said cam so Vformed that the roller 3l to he desorihed held normally against the edge of said @am may easily ride thereagainst and thereby run onto the no riphery of the member QS in'oper.l in which lastnamed portion it is shown in Fig. (3. Saidroller 31 is rotatahly mounted at the upper endof a member 3l" having' a springreceiving bore, the serevfthresided cnil oi" the knife member 39 screwing inte the transw '4 verse surface-of said channel-and heineA lim ited in its turning h V the shoulder Till formed upon said knife. The meiuhei Si telescoi'ies at the upper end of a socket niei'nher fl? having its bottom 54; dovetailed 'luto the meniher 34, the dovetailed portion heine; elongated and normally protruding at 3S) so as to he easily shilted and held in adjusted position, the memher 37 heing positioned near the peripherv of the men'iher 34 and said last-namedmemher will he of such a, diameter relatively of the cam head 28 that when it revolved the roller 31 may ride over the periphery of the cam head. 'The channel 86 3 in member 37 is formed with a reduced part tahle will ride against the depending studs 13,'

termimiting` in a relatively narrower part which is in registration with a vertical recess 33 .formed in member 34 into which the cutting surface oil the knife is held by means of the spring coiled around' said knife 70 and hearing at one end against 'shoulder 53 and-at the other against the shoulders formed by the narrow opening in member 37. Springs are seeuredlto the ends of the dogs and to the top of the talole respectively.

The can opener operates as follows;- By means of the screw Wheel 7 the user will raise the can table until the eau is brought alongside of hut at a slight distance apartl from the knife carrier 34;. To mount a can 80 in position upon the top 44 of the tahle the hand Wheel 15 will he revolved so as to advance the dogs i2 toward the center of thev By moving said wheel the cams 13 which forming'part of the blocks 42 will move them in their rectangular Openings 43 thereby imparting motion to the dogs 12 and causing them tomore forwardly or rearwardly. parvis 1i will ride over the teeth of the rack hars 9, and 10. Y[t will he understood that any suitable means may ne employed to r lease the pa-wls so as to retract the dogs in removing the can clamped thereby, no such S means being' shown in drawings, huiJ the provision of the means is Within the prov,- ince ot' those skilled in the art.

rifhe springs; are arranged to normally hold the dogs in engagement withl the pOr- 10u tion of narruu'est wiiilth of the cams so that they will he put under tension ywhen the cams are arranged to move them outof thelr nory mal position. i. o adjust the dogs so as to llp a can ot' any determinate width Vthe 1'05 wheel will he moved clockwise whereby the dogs will he moved toward the center, and il the ran resting at the center oi the table is oi" appropriate size the dogs will close against il. size that it is necessary to retract the dogs 1Q then the wheel lf2 can operate as follows: lefore placing the can on the table move said wheel cloelnvise amil the cams ride clear ol the dogs 12 and the pavsls il ride clearV of 115 the racks; .l and 10 uherenjwu,the springs will recoil aud restore the dogs to normal position. Continue lo rotate the wheel l5 until the broadest edge of each cam'is hrougfht info engagement u'it; 'the diamet- 12C Will then lm posilivclv .'iipiied. lVlien the 130 As the cams 13 move the 90 lf however, the can is ofsueh a is the c: vnis are moved 12V:

i opening mechanism may be; actuated`- Thev user will take hold ofthe handle of the lever downwardl can is 'thus gripped bv the dogs 12 and in the position clearly sioivn/ 1n F1g. 6 the"can 18 'and vill forcibly move it downwardly whereby shaft 16 guided in the collar i8 will in turn move downwardly and in consequence the screw-cylinder 2G will obey itsmovement and will move against the stud or pm 24m-ted. into the cam grooves Q3. The

lever will then lie-given a full stroke so that the topof cylinder 26 will move alongside the bar24 and owing to thc configuration of' the cam grooves and theposition of the pm .24 the screw cylinder Will rotate as it moves and will complete one ,revolution. It will be seen that said cylindeiI will move in telescoping relation Yagainst the polysided'upright shaft al and owing to the channel of said cylinder being polysided saidv shaft will rotate in common with said cylinder which will .also make 'a completev revolution. As said shaft 5l rotates the knife carrierA \vill obey its movement and roller 3l operatively mounted thereupon will ride off the edge of the cam way Q9 onto the periphery of the cam head 20, which head is stationary as aforesaid. iVhen this shall have been-done, the cutting edge ofthe knife Will have been caused to project through the openinor 33 in the knife carrier and Will penetrate Italle can and as said carrier completes its cycle of revolution, the knifewill cut the head of the can sufficiently to enable it to be bent back. "When the roller 3l is depressed as it engages the head of thecalu .vay, the member 3l' will move in the socket 'member 37 against the tension of the spring 35 thereby causing the knife 32 to advance against the head of the can to be eut. lYhen the cutting shall have been effected the lever 1 8 will move upwardly to its upper normal po` siton and as it is being restored the knife carrier will move to' occupy its first-named position, the roller 3l falling -into the cam way 29 and engaging `the edgethereof to lie adjacent the edge 30 of the cam head when the cylinder shall cease to rotate. This will have caused the spring to gradually recoil to lift the knife so as to hold it,out of projecting position. [t will.. he seen from the above construction that the operatorfcan .adjust the can against tbeknife carrier Without the hazard of injuring his fingers by means of' any projecting surface of theknife since the-latter is held concealed at all times until the lever is actuated. lThe knife carrier may or may not be in engagement with the 4can as .it rotates.

Numerous modifications may be resorted to in practice Without departing in .principle frmthe invention disclosed.
