heads 5 and vSand the margin 7 areushort-y ened vertically. and" as tlllSilS .done without permitting any enlargement of the diameter of the parts, the surplus metal in thebea'ds is forced to flow, inward and thus producea tightseal of the cap to the .jartopcausing the portion9 toconform. tightly toatheout side of the jar surface even though there is a. considerable irregularity in the diameters: and shapes of diiferentljars, v essels .o-r-containers upon which the caps are. used.

In a factory where a lot ofpackingis en gag-ed in, it is desirable mim a machine that will do thiswork-rapidlyand safely and lwithf dental d amaging of the 'jarsand-"caps "and to this end I provide a* machine llrtYll'lQ," a: rather broadbase frame 11 'which supportsan' upright base part member 12 into which is mounted an operating shaft 13 arranged to be driven by a pulley 14 and having a companion loose pulley15 over which pulleys a driving belt 16 shown in Figs. 4 and 8 operates the machine by power at intermittent intervals'as desired by the operator who -sets in motion the sealing operation through the mediumof a foottreadle 17 hinged at 18 to a block on base 11 of the machine. This foot treadle sets in motion as desired the sealing mechanism through the medium of a pinion 19 on the shaft 13 which engages and constantly drives a gear 20 on "a shaft 21-thus the gear 20 revolves in continuous motion so long as the belt 16 is'driving the shaft13 and this gear 20 is engaged by a clutch under the influence of the said foottreadle which 'sets' in intermittent motion the shaft 21 a single revolution of whichbrings about the sealing of a cap on a jar. Thus the shaft 21 amounts towhat may be termed a shaftof a punch press'and.revolves'acrank 22 which is connected to the reciprocating cross-head 25 forming a part of the sealing mechanism. On

' The 1 to be sealed at any given revolu} tion of the machine-is placedupon a floating table 29 provided witha registering block 30 adapted to seat the jar 1 in proper position on the table 29. This table 29 issupported on a plunger. 31, sliding in a hollow tubular post 32 in which there is a spring 33 providing for an elastlc connection in vertical arrangement'between the table 29 and the hollow tubular post 32." The screw 34 prevents the escape of the I pl-unger'31 from the tubular post 32.

The purpose of this spring connection of the table with the'post is to accommodatethe movement-of the jar in the sea-line operation. The post is mounted toslide vertically in ways 35 .of-a block 36 screw-ed to the frame post 12 by screws 37 and the tube or block 32 with its table 29 is raised and lowcred'as desired in the ways 35 bythe block 38 secured by a locking pin39 to the said post 32 and in the side of this'block 38 there is a hinge pin 40 to which a link 41 is connected and this link 41 ishinged to a pin 42 of the lever 43 hinged 'pin50 which extends through and carries bjlock-?5 1,so that the block 51} and block 49 moveftogetherpinall 'oftheir movements through this connection of the pin 50. 2A tension spring 48 tends to return the mechanism to its normal position.

The block 51 is connected by a peculiar clutch mechanism to the operating rod 52 which is connected at 53 to the foot treadle 17.

' Thus the movement of the foot treadle 17 downward results in moving the table 29 with its jar 1 thereon up into the embrace of the sealing mechanism. The return movement is brought about by the spring 48 and a secondary spring 54 connected to the treadle lever 17 and to a block 55 on the aforementioned pin 44. This connection of the spring 54 to the block 55 is simply a means of convenience as the said connection might be to any fixed portion of the frame and function substantially the same.

1 Upon the foot treadle' 17 being pushed downward, it actuates a clutch mechanism substantially the same as is involved in punch press operation to revolve the shaft 21 a single revolution the difference being that in theordinary punch press clutch mechanism whenever the foot treadle 17 is helddown the press Willcontinue torepeat itsstrokes but this is desired to be prevented in the operation of this machine and a peculiarly constructed clutch isprovidedto make it necessary that the operator release the foot treadle 17 and again press it down for each sealing operation of the machine thus serving'to insure the removal and'replacement of the ar sealed by the machine and this pe culiar clutch construction may be made in any suitable manner, but I prefer tomake it as here shown namely I r The revolving gear 20 amounts to: the fly wheel of an ordinary simple punch press and in the hub of this gearI'provide the-pockets 56 which are the engaging seats for an ordinary clutch pin 57 shown in dotted lines in Figs. 15 and 16. Thisclutch pin 57 mounted and carried by a block 58. see Fig. 3, which serves a triple purpose and is securelv fixed by any suitable fastening means to the shaft 21v and revolvestherewithf The outside diameter of this block 58 acts as a brake member in conjunction with a'brake strap block 59 set for braking purpose by a bolt 60. This 'brake'strap block-59 is connected to the frame of the machine by a screw 61. passing through the lug 62 of the brake strap block and secured into a lug 63of the frame which prevents-the rotation of the brake strap block '59. A suitable lining material 64 is provided for this brake.

Theright edge of'thisblock 58 is cbam fered olf atione spot as shown bv the dotted lines, Figures '3, 15 and 16 furnishing a flat cam surface 65 of a narrow width at the right side of the block looking in thedirection of iFig. 3; the purpose of which will be described later. 1 i J A- short shaft 66* is supported in bracket pieces 67 on the frame members carries an n which is engaged by a cam wheel 76 providedis connected.

arm 68 which withdraws the boltor clutch pin 57 at each revolution of the shaft-21- as; controlled bythe mechanism which connects-f the arm 68 with the foot treadle '17. 7 Mount ed also on the shaft 66 there is a bellcr'anlc lever 69 which. is connected by pin 70 into the slot 71 of the link 72 connected by a pin; 7 8 to the aforementioned arm'68,thuson the movement of the bell cranklever69beyond the limits of the slot 71 the arm 68 move's with the bell crank lever 69.

The bell crank lever'69 carries a pin7 l upon which there is mounted aijroller 75 with a cam notch 77 into which the roller 75' normally rests at the interval of rest of the sealing mechanism. Thebell' crankf-69 is providedwith an arm78 carrying the hinge pin which is connected to the 'blocksflS and 51 previously mentioned.

Mounted on the short shaft 66 there is a bell crank lever 79 having one end 80*operating on the'cam surface 0f thefblock 58 previously mentioned, and the other end 81' of this bell crank lever 79; shown'in dotted lines in'Figs. 15 and 16 and in full lines in Figs. 4 and 13, extends down and acts'asa detaching means for a clutch" devicein the said block 51 or rather a cylindrical extension thereof 82, see Figs. 13 and 14. Theblock 51 with its cylindrical extension 82 is" provided with a notch 83 which is engaged by the projection 84 of a lever 85,'hinged at" 86 to a block 87 towhich the treadlerod 52 scribed. 7

The arm 68is-iheld normally inipositien to engage the bolt or clutch pin 57 by inean sof a spring 91 connected at one end'to a fixed post 92 and at the other end to a"] 3i ]1-93,'in the said arm68, see Figs. 15 and 16. Thus'on the operation downward of th'ef'foot treadle 17 by the operator, the rod 52 being' engaged in the locked position of the clutch mecha; nism as illustrated in Figs. 13 and14, pullsdownward the pin 50 and carries with its block 49 and its connected parts and the bell crank lever 69 pulling the rollerf oeenom: positionof Fig5l5 tofathat of Fig. -l6, and simultaneously this movement through the link 72 disengages the arm 68 from the clutch pin 57 and allows the clutch pinto bee-11 gaged into a hole or pocket 56in thegear20z The movement of this pin 57- being brought about by a small spring 94sh'own' only-in dotted lines in Figs. 15 and 16( f Immediately 1 upon the release ofthe clutclilpin 57 the'shait 21 j with its connected mechanism,- a part of V WlllChjlS cam block-76,revolves-bringing the roller" 75;.then being'but' irom the cam-pocket,

[Underneath the flange 114 are provided fourdie or gripper blocks 115, held laterally by the side guides 116 of the flange 114 and supported vertically by a plate 117 underneath these dieblocks 115 and the plate 117 is held in place by screws 118 see Figs.

3 and 5. In the back end of these die blocks 115 there are notches 119 into which the cam blocks v112 are held laterally and the back side of the blocks 112 are sustained in align-.

ment by the cross blocks 120 which-check the backward thrust of the cam blocks-112 when their cam surfaces 113 engage theidie blocks 115 and push the said die blocks toward the center (see Fig.5) as the block 26 isr-aised by the cam 23 before described. The pins 121 secured intothe die blocks 115- extend upward through some slots 122 in the flange 114 and are engaged by plate springs 123 see Fig.- 12 which are held in place by the keepers 124 and screws 125. The result of these springs isto keep the dieblocks 115 always outward in contact with-the camsurfaces 113 of the cam blocks 112 so that on the downward movement of the block 26 the springs 123 act to reverse or throw outward the gripper or die blocks 115. 7 The gripper or die blocks 115 are provided with a cylindrical wall 126 and a shoulder or lip 127 and this shoulder where it joins'the wall 126 is undercut as indicated by 128.

In the operation of sealing the cap after the jar and cap to be sealed have been placed uponthe table 29a-s. is indicated by Fig. 3 the first movement broughta'bout is that of the foot treadle bringing the head of the jar with the cap upon it up into contact with thehead block 95 as is shown in dotted lines in Fig. 6, simultaneously the actionof the. foot treadle has set in motion the shaft 21"t hrough the.

clutch mechanisms'before described, thus revolving the cam 23 which results in. actuating the cam blocks 112 to move the die blocks ward toward. the jar bringing thefwalls 126 concentric-with the 'outsideyof the cap and jar and thegshoulders 127 underneath the margin 7 of the cap flange,v meantime'the.

pleting the ,seal of the cap upon the jar head. The work upon the flange of the .cap-

- On the completion of thestroke of the cross head 25 the machine againgoes .to rest in the normal position of Figs. 3 and 8 ready for admission of the next jar. I i

The wall 126 of thedie blocks 115 keeps the parts 4,' 5,6, and 7 of theflange of the cap from enlarging in diameter at all points save'at thepoint of the undercut 128 in the die blocks115 the purpose ofthis'being to allow the edge of the margin 7 of the cap to flow into this undercut 1 28 and prevent the curled over portion 8 from coming'in contact with the wallof the jar, thus keeping the outside metal or material ofthe cap from contact with the wall of the jar and allowing a, greater freedom of flow of the material of the cap to assemble'at the point 9 where the maximum seal contact is desired.

. The movement of thecap and iar from the position shown in Fig. 6 to that of Fig. 7'is permitted-by the spring 33 in the hollow post 32 as beforementioned. Y

Thus it will be seenthat jars having their caps previously applied, or applied to the jars by the operator as the machine .is. fed may be sealed substantially and rapidly as an operation maybe accomplished in simple ordinary punchpressiwork andthis with little or no danger of damage of glass jars or other receptacles which are desired to be sealed.
