JOHN M. HOTI-IERSALL, OF BROOKLYN, NEW YORK, AS'SIGNOR TO AMERICAN CAN COMPANY, OF NEW- YORK, N. Y., A CORPORATION OF NEW JERSEY.

CAN-CAP-LINING APPARATUS.

Application filed March 5, 1923. Serial No. 622,732.

To all whom it may concern:

Be it known that. 1. JOHN M. l-lo'rHnnsALL, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of N cw York, have invented a new and useful Improvement in Can-Cap-Lining Apparatus, of whiclr-the following is a specification.

M y invention relates to apparatus for lining can covers, or the like, with a gasket material such as combined paper or felt and tin foil. In the type of container which is closed by a. screw closure and adapted to contain oil or other liquid contents, it is necessary' that the closure be lined with a material of this character which ordinarily is applied in the form of a disk seated in the top of the closure and adapted to be brought down upon the neck of the can to prevent leakage when the latter is closed. My invention .contemplates the provision of apparatus for not only forming strips of the desired combination of materials, but also for cutting out disks or liners from the formed strip and applying them to the covers.

It is also an object of the invention to provide means for controlling the'feeding of the liner materialso that no liner is cut therefrom when there is no cover advanced to position to be lined.

Another object is the provision of a machine unit adapted to perform the several operations necessary to form and apply liners of this character in fully automatic and eflicient manner and by the utilization of-a single source of power.

Other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a 1 preferred embodiment thereof. Referring to the drawings, A Figure 1 is a general .side elevation of the apparatus inwhich my invention is embodied; Fig. 2 is a side elevation showing more in detail the construction of the strip feeding i and liner applying machine; Fig. 3 is a front elevation of said machine;

Fig. 11 is a section taken substantially on the line. 1111 in Fig. 4.

. The apparatus as illustrated comprises 7 two main units, namely the feed and punch press 11 and a gluing machine 12. The latter consists of a supporting frame 13, in the lower part of which there is mounted a drum 14 upon which is wound a supply of .7

paper, felt, or other suitable material which is adapted to be directed upwardly over a roller 15 and between

rollers

16 and 17, the former being mounted to pass through a glue receptacle, 18 as it revolves. Said drum 1 1 is secured upon a. transverse shaft 19 rotatably supported'in bearing brackets 21 on the frame 13. The roller 15 has bearings in a bracket 22 on the frame 13 and a second roller 23 is mounted in the upper part of said bracket. The roller 16 is su ported upon point bearings 24 provided 1n upstanding brackets 25 at the sides of the receptacle 18, and a scraper 26 is positioned upon a cross piece 27 (Figs. 8 and 9) in such manner that the roller 16 passes between side fingers 28 on said scraper. An upper.- guide 29 is provided above the scraper and serves to direct a strip 31 onto the roller 16. Said scraper is adjustably secured in place by means of a screw 32 and serves to control the amount, of glue adhering to said roller 16. as the latterturns having turned out of the glue receptacle 18 applies glue to the strip 31. The roller 17 is mounted in side brackets 33 and is provided with a groove 34 in which the strip 31 is held as the glue is applied thereto by theroller 16. Thestrip 31, with glue applied thereto, is directed over the roller '23. and

between feed rolls 35 and 36' (Fig. 5) in the press 11. A drain pipe 40 may be'proi and is normally closed by a cap 40 or in any suit-able manner.

Said press 11 is supported on a base 37 by means of a frame 38, which latter is adjustably secured in said base by means of bolts 39 taking through slots 41. A drum 42, mounted in brackets 43 in the upper part of the frame 38, contains a supply of tin foil, or the like, which is fed between the rollers and 36, the tin foil strip 44 being directed between said rollers above against the side of the paper or felt strip 31 to p which the glue has been applied. In this manner, the strips are glued together and the resulting duplex strip advanced-t0 the gasket punching and applying station.

Said feed rolls 35 and 36 are operated from a rock shaft 45 by'mechanism to be now described. The roller 35 is carried on a shaft 46 .which is rotated by means of a 'ratchet device 47 connected by a rod 48 '51 without turning the shaft 46.

The rock shaft 45 is driven from a main power. shaft 54 by means of a crank 55 and pitman 56, which latter is connected to an arm 57 mounted on the shaft 45. The power shaft 54 is provided with tight and loose pulleys 58'and 59, which latter may be driven from any suitable source of power. A brake 60 is provided on the said shaft 54, to positively stop each press stroke, when desired,-

and prevent overthrow, this being a common construction on all presses.

The amount of, stroke given to the rod 48 is variable by means of a set screw 61 provided in a projection 62 on a. sleeve 63 and when said sleeve is connected to the shaft 45, by means to be hereinafter described, the rod 48 is actuated to operate the feed rolls .35 and 36, in manner which will be apparent on viewing Fig. 5. These rolls advance the duplex strip across a support 64 and through a guide 65 arranged above a. channel 66 through which caps 67 to be lined are fed (see Figs. '3, 5 and 6). A punch 68 is operated by means of a crosshead 69 operable by the shaft 54. Said punch is yieldingly mounted in a sleeve 71 under the tension of a spring 72 and is adapted to be projected by an arm 73, (Fig. 3) one end of which engages a stop 73 on the frame 38 on the downward stroke of the crosshead 69. The caps 67 (Fig; 6) are fed through a chute 74 into the channel 66 and are advanced therein by means of a slide 75 having dogs '7 6 mounted therein and normally held in upper position by springs 77. Said slide is operated from the shaft 45 by means of a cam 78 acting upon a roller 79 carried on an arm 81, the latter being secured to the upper end of a short .vert-ical shaft 82 having bearings in a bracket 83 on the main frame and having secured thereto at its lower end a second arm 84 which is connected by a rod 85 with said slide 75. that covers are advanced on the forward movement of the slide 75 and it is noted that they are held in advanced position by means of

pawls

86 and 87, which latter are held under the tension of springs 8'7, the dogs 76 being allowed to be depressed to position ben'eaththe top of the slide onthe return stroke. At the proper time, the punch 68 descends, cutting out a disk from the duplex strip which is designated by the reference character 88 (Fig. 6), said diskbeing also seated by the punch in the cap which is in position beneath an aperture 89 through which the punch operates. Upon the next forward movement of the slide '75, the lined cover is advanced and a new cover positioned to be lined, the punching operation being so timed with reference to the feeding of the caps that a gasket or liner is punched out and applied to each cover as presented. -The lined covers are ejected from the channel66 into any suitable receptacle.

An important feature of the apparatus consists of a device for controlling the feed- It will be manifesting of the liner material so that the strip is not advanced in-the absence of a cap in position to be lined, thus preventing the wastage which would otherwise result. A bar 91 is arranged transversely of'the channel 66, being supported upon rods 92 secured at their lower ends to a plate 93 (Fig. 5) which is connected b 95 to a shaft-.96. aid link 94 is pivoted at 97 and 98 to the plate 93 and the arm 95, respectively. Springs 99 are provided on the rods 92 extending from the plate 93 into sockets 101 in the frame. It will be manifest that said springs tend to draw the rods 92 and the plate 91 downwardly in the chana link 94and an arm nel 66. An arm 102 is mounted on the shaft 96 and connects at its oppositeend with a rod 103. Said rod is secured atits opposite end in an arm 104, which is pivoted at 105 to a frame bracket 106 and carries a cam roller 107 in an intermediate projection 108.

Said roller is adapted to ride upon a cam- 67 be present beneath said bar, which it will. be noted is positioned at the station immediately preceding the liner applying station, said bar rests thereon and the rod 103 is not permitted to move an appreciable distance.

Referring now to Figs. 5 and 10, it will be observed that the rear end 112 of the rod 103 engages a tail part 113 of a pawl 114, which latter engages a ratchet 115 on the shaft 45. The pawl 114 is pivoted on av part 117 and is normally held in engagement with the ratchet 115 bymeans of a spring-pressed pin 116 engaging the part 113. If no cover be present, the rod 103 is moved rearwardly, disengaging the pawl 114 from-the ratchet. If, however, an end be present, said pawl remains in engagement with said ratch and acts upon a part 117 which is rigid with the sleeve 63, causing the latter to turn in clockwise direction, viewing Fig. 10. This lifts the rod 48, which, on the return stroke rotates the roller to advance the strip of liner material. Said roller 35 is connected by gearing 118 with the lower roller 36 so that these rollers cooperate on the return stroke of the rod 48 to feed the strip. In this connection, it will be noted that the part 117 has a shoulder 119 engaging the ratchet wheel 115, so that the rocking of the shaft in counter-clockwise direction actuates the sleeve 63 and therewith the rod 48. It will thus be manifest that the feeding is accomplished only when a cap is advancing to the lining station and that the feeding of the liner material and of the caps to be lined is so related that liners may be cut and applied as the successive caps come to rest beneath the punch 68.

The cam 109 is fixed on the shaft 45 so that the recess 111 passes back and forth under the roller 107 this operation being caused by the rod 56. When thereis a normal feed of covers, however, the roller cannot be pressed by the springs 99 into said.

recess because the bar 91 will be sustained by a cover in proper place; but when a cover is not so present the roller will enter the recess and the rod 103 will displace the pawl 114 so that it will not move the part 117 or the sleeve 63 or the rod 48, and no feeding. of the lining material 88 will occur, because there is no actuating connection.between the sleeve 63 and the shaft 45.

The shaft 45 is mounted in bearings 121- and 122 in

frame brackets

106 and 124 and a brake 125, illustrated in detail inFig. 11, is provided between the bearing 122 and the sleeve 63 to prevent overthrow by momen tum. Said brake is attached by a bolt126 to a depending lug 127 on the bearing 122 and consists of clamping

jaws

128 and 129 hinged at 131 and adapted to be tightened by means of a spring bolt 132. a

my machine a gasket strip composed of more than two materials could easily be produced and I do not wish to limit myself to a duplex strip and I intend the word duplex as used by me to comprehend a plurality of layers of material.
