To all 'whom it may concern:

Be it known that l, lViLLIAM F. BUTLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Applying Cement to Gan-Caps, of which the following is a specification.

In the use of cans or packages of a certain type, a liquid or viscouscement is placed between a portion of the main body of the can or package and a portion of the cover before the cover is arranged in final position.

The object of my invention is to produce an efficient apparatus to automatically ap: ply such cement or sealing material.

The accompanying drawings illustrate my invention. 1

Figure 1 is a plan of a machine embodying my invention; Fig. 2 an elevation in partial vertical section; i0'. 3 a section on line 3-3 of Fig. 2; Fig. 4 a detail section on line 4-4 of Fig. 2; Fig. 5a similar section on line 5 5 of Fig. 2; Fig. 6 an enlarged sectional detail of an effective form of delivering means for the cement; Fig. 7 a similar section at right angles to Fig. 6; Fig. 8 a detail ofa part of the cap feeder; Fig. 9 a section of a' can or package ofthe character referred to, and Fig. V10 an elevation, in partial vertical section, of a modified form of machine embodying my invention.

In the drawings, Figs. 1 to 8 inclusive, 10 indicates a suitable main frame comprising a feed table 11, inwhich, between Suitable guides 12, is arranged a feed slide 13. Journaled in frame 10 -is a main drive shaft 14 provided with a crank 15 connected to the feed slide by a link 16. Arrangedin 2the' delivery end of table 11 is a rotary table 17 carried at the upper end of a shaft 18 connected by a pinion 19 and a gear 20 with shaft 14, the gears being so proportioned that table 17 Will be turned comparatively rapidly and preferably at least three com.-.

plete rotations each actuation, for a purpose which will appear. The upper face of the table 17 is even withthe face of table 11 and is provided with several concentric grooves 17 iso-facilitate the centering of caps 21- of different sizes each of said caps having an annular groove 22A for the reception of a thin layer of cement 100.

Arranged above tablel? is a cement delive ering spout, 25 which may be adjusted toward and from the axis of table 17 So as to aline with the cement-receiving grooves of caps of various sizes, lsuch adjustment being accomplished, in the present machine, by

,bolt 26 passed through slot 2T .of the supporting arm 28. Spout 25 is carried vby a' pump body 29 having a chamber '30 communicating with the interior of the spout. Intersecting chamber 3() is a passage protected at each end by a packing gland 31, and' in which yis mounted a valve 32 having a passage 83 adapted to aline with chamber 30. Mounted in the pump body 29, and alined with chamber 30, is a pump piston 34 connected by a link 35 with a block-36 adjustablymounted Ona lever 37 parallel with d the lineof adjustment of the spout 25. Lever 37 is connected by a link 38 with a lever 39 actuated in both directions by a cam 40 carried by a shaft 41 connected by a 75 suitable driving-chain 42 with shaft 14, so as to be rotated in unison with shaft 14. u

Leading into the side of the passage in which valve 32 is mounted is, an inlet passage 44 which communicates with a cement reservoir 45 through a tube 46 the arrangement being such that cement may flow freely from the reservoir into the pump cylinder. Reservoir 45 is mounted suitable ways 47 so that it may partake` of the adjustment of the spout and4 pump and, in order to keep the cement in good. condition, I provide a stirrer 4S carried by a shaft 49 having a crown-friction wheel 49 on its lower end adapted tobe engaged by a cylindrical friction wheel 50 carried by shaft 14.

In order toprevent waste of cement, and to keep table 17 clean, when no cap is in proper position to receive the cement I provide, centrally above table 17, a plunger or= holder 51 normally urged'downward toward the table 17 by means of a spring 52. Connected to plunger 51 is a lever 53 by means; of which the plunger may be lifted against the action 'of spring v52, the said lever having one endy arranged .in the path of moveli'nent of a cam l54 carried by shaft 41. Valve andbrixig the L-shaped passage 58 of the.

- cam 69 valve into alinement with the pump cylinder and the inlet 44 (Fig. 7 1When the valve is in the position just mentioned, a notch 59, in the outer end of valve 32 lies in alinemeut with a locking bar 60 connected by alink 61 with the upper end of plunger 51.

In order to feed the caps to the table 17 and remove the .same therefrom after the cement has'been applied, I provide the following mechanism. p' Slide 13 is provided with a capreceiving notch 65 at its forward end, to which the caps may be successively fed through the common feed chute (not shown) .and the stroke of theslide is siiiii'- cient to carry eachcap from such chiite to the table 17. In lorder to prevent'tilting of the caps l deem it advisable to displace ,a treated cap by means Nother than the oncoming ycaps and for this purpose provide slide 13 with a forwardly extending arm 66 which', at its forward end carries a pivoted usher finger 67 adapted to lie projected into the'path of movement of the oncoming caps or tolie retracted-therefrom. Finger 67 carries a piny68 adapted to engagea stationary cam or "guide 69 arranged aloiigits path of movement. At the forward end of is a pivoted spring-pressed guide finger 70 and at the rear end of said cam is a guide finger 71 similar to finger 70 but reversely positioned. i v i With the parts inthe positions shown in the drawings one. rotation of shaft l14 in fthe direction indicated in Fig. 3 will cause three complete rotations of table 17 and a down-stroke of piston 34 so as to force a stream of cement into the groove 22 of cap 21. Piston 34 and plunger 51 then move upward and slide 13 moves forward bringing inger 67 into engagement with the cap on table 17 and carrying it over into the discharge chiite 72,v a newcap being, at the same time, driven forward byslide 13 and deposited on the table 17 where it is readily` centered by the appropriate groove 17 Cam 54v now permits plunger 51 to descend Aupon the freshly placed cap on table 17 and said plunger, resting on the cap, prevents the loclr-bar v from descending low enough to enter notch 59, valve 32 being at this moment held in the position shown in Fig. 7, by cam 57 but quickly returned to the position shown in Fig. 6. Slide 13 thereupon returns and, pin 68 engaging iinger 71, the finger 67 is swung into line with arm 66'(see Fig. 8) 'so as not to engage or interfere with the newly placed cap on table Y 17. At the same time table 17 is rotated by gears 19 and 20, vand pump plunger 34 driven downward by'cam 40 so as to deliver k.a stream of cement into the channel 22 of thecap. yBy rotating table 17 several'revolutions during the time of deliveryof the cement an adequate distribution of the cement is insured. When slide 13 reaches the cap should be end of its return movement pin G8 Vof finger 67 has passed fingervO so that, at the bevginning of the next forward movement of the slide, finger 67 is thrown into cap-engaging'position. If, by any chance, no

51 will descend far enoughv to permit the locking bar 60 to enter notch 59 of valve 32 and hold the valve in the position shown in Fig. 7 until'aftci the pump piston has descended. ln this position communication betweenv the pump and nozzle 25 is cut off by valve and the passage 5S forms a coin- `munication between the pump and tube 41' so 4thatany cement in the pump above valve 32 may pass freely back into tube 4&3, thus preventing any material pressure' iii 'the pump which might tend to 4canse the iinprisoned cement to be forced out through the various packing glands or to cause a straining of the pump-actuating pai-ts.`

By connecting the reservoir 45 with the pump body 29 and providing the 'cylinderand-crown friction drive 4950 for the stirrer 48 only a single fastening is necessary for enabling proper adjustment of all` the cement delivering mechanism.

In the form shown in Fig. 10, the rotary table 17 is driven from a main shaft 80, the can caps being placed on the table 17 in the, same manner asin the other machine, and held thereon by a plunger 81, normally urged downward by a spring 8 2. Connectedto plunger 81 is a lever 83 having a notch 84 adapted to engage one arm of a belldelivered to table 17, plunger crank-lever 85 whenever plunger 81 descends as low as is possibley when no cap is on the table. Lever 85 is actuated in one directionby a cam 86 and in the other by a spring S7. Connected to lever 85, by a link S8, is a valve 89 which controls outiiow from a nozzle 90 like nozzle 25. Nozzle 90 is the outlet-of a pump 91 connected to the cement reservoir 92 and provided with a piston 93 connected to'a lever 94 actuated by a camrod 95 and cam 96.
