of any diameter to bottles, jars or other eontainer and it is my object toproduce a machine in which the pressure, while sufficient to accomplish the not rise high enough to break the result, will container, which can be adjusted to cap containers of different heights, which willcompensate for countered variations of the containers enin commercial operation an which will cap a container although the same may have been positioned 'on the table in such manner as to lnltially receive pressure on but a portion of the cap. In the drawing Fig. 1 is a my machine; Fig. 2

front view of a side view thereof and Fig. 3 a sectional view of the feed table on the line 3'3 of Fig. 1.

. The machine, comprises supporting a table frame 2 which may be raised or lowered by loosening the bolt 3 and turning the screw feed 4:. This adjustment is used principally to aline the table .with the filling machine.

This table frame carries a plurality (5f rollers 5 and drums 6" 6 at either end thereof, the upper surfaces of the drums and rollers all nin g.

belt 7 passes over the rollers and drums, a tensioning' device 8 being provided to keep it taut.

Located over the table and on themain frame is a pressure applying head block 9 vertically adjustable by a This block carries a pair and 12, each of which has a gear 14) secured thereto of gears feed screw 10. of crank disks 11 13 (and and also carries a train 15'which transmit motion from one crank disk to the other.

Suspended from disks are a pair of the pins on the crank links 16 and 17 whose lower ends are rigidly secured to a plate 18.

A presser plate 19 the plate 18 by pairs of cured to the plate the plate 18 with spring between the plates.

is yieldingly secured to studs 20 and 21, se- 19 and passing through s 22, 23 interposed ThlS permits the plate 19 to yield upwardly with respect to the plate'18.

To revolve the crank disks 11 and 12 a main drive shaft 24 is journalled onthe mawith a'bevel gear 26 which is journalled on the frame. A sp lined shaft 27 passes through the gear 26 and is free to slide therein but revolves passing through a therewith, the lower end bearing 28 on the bee u to machines for apd or lowered without a "main frame'l containers pass under the sealing block '9 and carries abevel gear 29 which disk 12. a

As the shaft 24 is revolved it will revolve the shaft 27 and revolve the crank disks with their gear train transmitting the motion from one disk to the other.-

shaft 27 permits the head block tobe raised transmission of power.

To drive the feed table belt a gear 3l,secured to the gear 26 meshes with a gear32 also joilrnalled on the main frame. A splined shaft 33 passes slidably through the gear 32 and has its lower end in a bearing 34 on the table frame 2. A gear 35 on the shaft'33 meshes with a gear 36 on the drum 6. As

the shaft 33 is revolved the drum 6 will drive the belt 7 and cause it to travel under the presser head and over the supporting rollers 5. y

The speeds of the shafts 27 and 33 are so calculated that when the plate 19 is in its lowest position and in contact with a cap on a container it will be travelling laterally at the same speed as the belt 7.

The operation of the machine is as follows :-The table is set level with the filling machine to receive the filled containers. The sealinghead is adjusted up or down so that the plate 19 will exert a driving, sealing pressure on the caps, which are loosely laid on the containers, as the capped containers pass under the head. As the loosely capped head which is moving up and down'and laterally: due to the crank motion, the plate 19 forces the closures tightly onto the containers. The

the plate 19 to yield under'pressure and prevent breakage of the containers. They also act as compensator-s for containers of slightly varying heights.

"If a container is placed on the belt at such time as the plate '19 will not press on the entire surface of the closure the next stroke of the sealing head will engage the entire closuie because the plate 19 is of sufficient length, and the speedof the belt is such that .each closure must receive a full area pressure stroke before it has travelled from one side of themachine to the other. I claim 2- 1'. A machine for aflixing closures to cond tainers comprising a frame, a pair of drums,

The slidingsplined connection between the gear 26 and interfering with the said belt, a pair of crank diskson said head,

' -crank pins thereon, links suspended from Said pins, a presser plate rigidly secured to the lower ends of said links, me ns for moving said presser head vertically, a drive shaft journalled on said frame, a gear journalled on said frame, a shaft passing through said gear and splined'thereto, a gear on the lower end of the shaft engaging the drum gear, means for driving said jofirnalled frame gear from the drive shaft and for rotating the crank disks in synchronism with the splined shaft whereby the belt and presser plate will travel laterally at the same speed when the plate is" in contact with a closure.

2. A machineffor afiixing closures to containers comprising a frame, a drive shaft and a gear thereon on said frame; gears journelled to said frame one of which engages the drive shaft gear, a head block mounted on said frame, a pair of crank disks on said block, a gear on one of said disks, means for transmitting motion from one disk to the other, a shaft splined to the journalled gear engaging the shaft gear, agear on the lower end of said shaft engaging the disk gear,

the lower end of the second shaft engaging the drum gear whereby the belt and presser plate are synchronously driven so that their lateral travel is the same while the presser plate is in contact with a closure.

In testimony whereof I have affixed my signature.
