UNITED STATES AUGUST M. AUGENSEN,
OF GRAND JUNCTION, COLORADO.
CAN-CAP-SEAIVIING APPARATUS FOR VARNISH CANS, ETC.
Application filed April 22, 1920.
T all whom it may concern:
Be it known that I, AUGUST M. Anon):- snN, a citizen of the United States, and a resident of Grand Junction, in the county of Mesa and State of Colorado,have invented certain new and useful Improve: ments in Can-Capfieaming Apparatus for Varnish Cans, Etc, of which the following is a full, clear, and exact specification.
My invention is concerned with can cap seaming machinery for varnish cans, etc, and is designed to produce a novel power operated device of the class described which is at all times under the control of the operator, so that it can be more certainly Inanipulated than can theprior poweroperated devices with which I am familiar, and thus be employed in capping cans of shapes which could not readily be handled by ordinary means.
To these ends, it consists of the novel struc ture hereinafter fully described and particularly pointed out in the claims.
To illustrate my invention I annex hereto two sheets of drawings in which the same reference characters are used to designate identical parts in all the figures of which Figure 1 is a view partly in central longitudinal section showing a part of my invention as applied to a hand tool;
Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig. 3 is a vertical section through a can and cap of the character for which my invention is designed, before the cap has been secured in place;
Fig. 4 is a similar view after the cap has been secured in place;
F ig. 5 is a side elevation of my invention in its preferred form applied to a power operated machine; and
Fig. 6 is an enlarged detail of the same.
Some forms of cans, such for instance as varnish cans, have a generally square or rectangular body 10 with a funnel 11 secured in one corner thereof through which the can is filled, and after it is filled, a cap 12 is placed over the open upper end of the funnel with the downwardly projecting flange 13. To seal the same, the flange 13 must be turned in, as seen in Fig. 4: and the object of my invention is toproduce an apparatus which will readily perform this function.
In Figs. 1 and 2, I have shown a hand tool adapted for this purpose, which consists pri- Serial No. 375,680.
marilyof a supporting shaft 1 1, which has are fulcrumed the levers 17 upon the fulcrum pins 18. These levers have the seaming rolls 19 journaled on their lower ends, and preferably held in place by having the flange 20 on their upper end resting in all positions of the apparatus upon the upper edge of the flange 21 of the clamping chuck 22, which consists of a rotary member circular in its horizontal cross section and having the under surface 23 of the proper shape to fit snugly in the top of the particular cap 12 for which it is designed. The upper end 2 1 is reduced and fits in a correspondingly shaped circular recess 25 in the under side of the head 15, and is preferably provided with an annular groove 26, semicircular in cross section, with which groove cooperate one or more pins 27 driven into the head 15 so as to engage said groove 26 and hold the chuck in place while not interfering with its rotation in the head. In order to diminish the friction resulting from any relative rotation of the head 15 and the chuck 22, I preferably interpose a set of ball bearings 28 between the groove bearing rings 29 and 30 seated respectively in the under side of the head 15 and on the upper side of the chuck 22. For hand use, the shaft let has the handle 31 secured on the reduced upper end 32 thereof, as by the screw 83, while a sleeve 34: having the flaring conical end 35 terminates the lower end thereof in position so that as the sleeve is raised by pullingon the handle 36 secured on the upper end thereof, the cone 35 will force the upper ends of the levers l7 outward bringing the seaming rolls 19 into the proper position to crimp the flange 13 to the position shown in Fig. 4 when the shaft 14: is turned. A helically coiled expanding spring 37 is interposed about the shaft 14 between the handles 31 and 36 so as to keep the sleeve down in position where the chuck 22 can be readily placed on the top of the cap 12. When this is done, the operator presses down on the handle 31 at the same time with his fingers drawing up the handle 36 so as to force the crimping rolls 19 inward, and then turns the handles and thereby. the shaft 14:- The pressure of the chuck 22 on the cap holds it from turning, and the rolls l9 consequently roll around on the that side of the head 63.
\Vhere my invention is applied to a power machine, I employ the base 38, which is preferably mounted on wheels or rollers 39 and has the central hollow standard 40. Secured to the side of the standard is the bracket arm 41 which has the vertical bearing sleeve 42 to accommodate the tube 43 mounted to slide up and down therein and having one end of the lever 44 pivoted to its lower end. This lever 44 is fulcrumed to the standard 40 at 45, and has the link 46 pivoted to its other end and extending down to a treadle 47 fulcrumed on the base 38 at 48; The supporting chuck 49, which preferably takes the form of a disk, flat on its upper surface, and with a flattened conical under side, issecured on the upper end of the rod 50 which has a plurality of apertures 51 therein through which a pin may be passed in connection with a pair of apertures in the tube 43 to regulate the position of the head of the supporting chuck 49.
A- motor 52 may be secured on the base 38 and has the spur gear inion 53 on its armature shaft meshing with the spur gear wheel 54 secured on the driving shaft 55 journaled in the bearings 56 projecting upward from the base 38. A belt pulley 57 secured on the other end of the shaft is connected by the belt 58 with a larger belt pulley 59 secured on the driving shaft 60 which is journaled in the bearings 61 and 62 formed on the upper end of the generally hollow head 63 secured on the top of the standard 40. The shaft 60 is preferably mounted so as to have a slight longitudinal movement in the bearings 61 and 62 so as to bring the beveled friction wheel 64 onto or ,out of engagement with the corresponding beveled friction wheel 65 secured on the upper end of the shaft 14*. This shaft 14 is jou'rnaled in the vertical bearing 66 formed in the bracket 67 projecting from The engaging surfaces of the friction wheels 64 and 65 are preferably covered with rawhide or some tion roller 71 which is engaged by the cam surface 72 on the bar 73 which is mounted to slide, as shown, in the bearings 74 and 75 formed in the sides'of the head 63. A short link 76 is pivoted at one end to the slide 73, while its other end is pivoted to the lever arm 7 7 on the hollow inside of the head 63, which arm 77 is secured to the rock shaft 78 journaled in said head and having one end extending outside thereof so that the operating handle 79 can be readily secured thereto. The shaft 14, instead of having the head 15 directly secured thereto, preferably has a tapering socket 80 in its lower end which is adapted to receive the tapered end 81 of the shaft 14 upon which slides cone 35 which has the annular channel 34 at its upper end adapted to receive the forked end 82 of the lever 83 which is fulcrumed at 84 between a pair of ears 85 extending downward from the under side of the head 63. A lever 86 is journaled on the same fulcrum and has an arm 87 extending under the lever 83 so that a setscrew 88 screwed through the arm 87 serves to regulate the position of the lever 83 to a. nicety. The lever 86 has the anti-friction roller 89 in its upper end adapted to co-operate with the cam surface 90 formed on the under side of the bar 73. The levers 17 are em-' ployed as before, but with the power operated head, a pair of these levers and crimping rolls 19 are sufficient, whereas 1 preferably employ four with the hand operated device. The clamping chuck 22 is the same as before and is secured to rotate in the head 15 as before, but I may place the ball bearings 28 between the top of the reduced portion 24 and the bottom of the socket 25.
The fundamental operation of the power operated device is the same as the hand operated device, only it will be understood that the can 10 is placed on the supporting chuck 49 after which the pedal 47 is depressed to raise the chuck 49 to bring the cap 12 in engagement with the clamping chuck 22 This being done by the foot lever while the can 10 is free to be manipulated by the hands, it is possible to position the clamping chuck accurately on the cap 12 in spite of the eccentric location of the funnel, a thing that would be very difiicult if not impossible to do if the movement of the supporting chuck was by power. WVhen the can is positioned and clamped between the chucks 22 and 49, the lever 79 is swung to pull the bar 73 downward, and. this move ment first causes the cam 72 to engage the roller 71 on the end of the lever 68, to bring the wheel 64 in operative engagement with the wheel 65 which starts. the head 15 to rotate. The further movement of the bar 73 causes the cam surface 90 to engage the roller 89 and swing the lever 86 to in turn llU invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable ofmodifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.
