Specification of Letters Patent.

Patented Nov. '7, 1911..

Application filed March 2 6, 1907. Serial No. 364,602.

To all whom cit-may concern:

Be it known that I, FREDERICK Rnorrr, a citizen of the United States of America, and a resident of the borough of Brooklyin-in the city of New York, county of Kings, and. State of New York, have invented certain new and usefuliflmprovements in Machines for Applying Caps tp Bottles, of which the following is a specification.

- This invention relates to machines for applying sealing caps to the mouths of bottles.

The machine illustrated is intended especially for the application of a metallic sealing cap or bottle seal which is provided with a compressible or elastic sealing medium, as a disk of cork, and means for locking the cap to the bottle, and more particularly for the application of the-form of cap set'forth in Letters Patent of the United States No. 646,627 granted to me April 3, 1900, and an improvement thereon set forth in Letters Patent of the United States No. 796,354, granted August 1, 1905, on my application.

' This form of cap is provided with a, locking each revolution of the machine.

wire which has a loop pendant from the edge of the cap. By reason of this form conditions are imposed in the automatic handling which do not arise with a form of sealing ca without such a pendant wire loop. Suc caps are conveniently supplied by the manufacturer arranged in pasteboard containers consisting of tubes which have been slitted lengthwise so that the sheefimetal portions of the'caps with the sealing disks maybe stacked within the tube while the wires extend through the slot and the loops lie'outside the tube as illustrated in a plicatio'n for Letters Patent'of theiUnited tates filed by me January 13, 1906, Serial No. 295,864.

One object of the inventionds to provide a machine in which caps such a'shave been above defined are fed automatically, it being necessary merely to set a container with caps in proper position in the machine and the caps will be fed therefrom and brought into position for applying to a bottle at Such caps can, I find, be most. satisfactorily applied by means of a specially constructed head or chuck which receives the cap and through which pressure is applied in the direction of, the bottle axis by relative movement of the I head and support for the bottle to efl'ect sealing contact between the cap and bottle and-their locking together, such a chuck be- "ing set forth 111 application-[for Letters Patent ofthe United States filed by me September2, 1904, Ser. No. 223,088. The axial pressure requisite is considerable and the power expended is proportionate to, the dis-.

tance through which the moving parts are required to travel while the pressure is sustained. Such distanoe,with power-driven mechanism wherein parts of the transmitting mechanism.-have fixed distances of travel, can be reduced to a minimum by close adjustment of the nearness of approach of the supportfor. the bottle and the pressure-ape plying head according to the height of the. bittle tobe capped. Where there is variation in the heights of bottles for which individual gagingand manual adjustment is impracticable,.such adjustment is made for the shortest bottle of the lot, and heretofore when longer bottles are placed. in the machine, the pressure is applied at an earlier oint in the movement and sustained for a onger time with consequent waste of power, excessive pressure, danger of breaka e, and curtailment of the time of the machine which can be allotted to the operations of bringingthe caps into position and removal of the capped bottles.

A further object of the invention is to pro vide means by which the application of the heavy sealing pressure is held back or delayed in the case of the longer bottles being capped, and applied only toward the end of each stroke of the machine and at the same point in the stroke measured from its completion irrespective of the height of the bottle, whereby the pressure is sustained only through the required distance and no more with all heights of bottles within the capacity of the machine with a given manual adjustment.

Further objects of the invention relate to 0 devices for safeguarding the operation of the machine.

In the accompanying seven sheets of drawings which form a partof this application is illustrated a power capping machine embodying myjnvention in which,

Figure 1 is a front elevation of the lower portion of the machine, showing the driving pulley, starting mechanism, crank and cam shaft and transmission mechanism to the support for the bottle. Fig. 2 is a side elevation of the lower portion, omitting the pulley. Fig. 3 is a vertical section of the lower portion on the line IIIIII of Fig. 1. Fig. 4 is a front elevation of the upper portion of the machine showing the holder for cap containers in section, the pressureapplying turret-head with chucks for holdingthe caps, cap-feeding mechanism and actuating mechanism. Fig. 5 is a side elevation of the upper portion. Fig. 6 is a vertical section of-the upper portion on the line VI of Fig. 5 Fig. 7 is a vertical section of the upper portion on the line VII of Fig. 5. Fig, 8 is a section at one end of the crank shaft on the line VIII-VIII of Fig. 1, showing the clutch mechanism. Fig. 9 is .a plan of the end of theslide for ejecting caps from the tubes. I

The machine is power driven by. a belt on a pulley or fly wheel 1. This pulley runs loosely on a crank and cam shaft 2, and a. collar 3keyed to the shaft carries a bolt 4 engaging with the pulley. A knob on the bolt is engaged by a pivoted'wedge 5 at each revolution of the machine and the bolt thereby. withdrawn from engagement with the pulley. The pivoted wedge connects through an arm 6 and latch 7 with a treadle 8 by which'the machine is started. A stud 9 throws oil the latchwhen the treadle is depressed, thereby permitting the wedge to return to engaging position if the treadle is held down, and'the pivoted Wedge also has an arm 10 which is engaged by a cam 11 and the pivoted wedge positively returned into position to engage with thebolt and stop the machine at the completion of a. revolution, thereby necessitatingthe depressing of the treadle for each revolution.

A pitman 12 connects the crank of the crank shaft with the junction point of toggle members. The lower of the toggle members consists of two telescoping parts, an upper part'13 hinged at the junction point of the toggle members, and a lower part 14 hinged to suitable .abutments. The abutments are eye-bolts 15 15 held in place by heavy compression springs 16 16. The tension of these springs may be such that the eye-bolts do not move in the ordinary operation of the machine, and act as substantially rigid abutments. These springs serve as a. safeguard in event of the machine being operated with anything therein which is less elastic than a bottle and unused cap, as for example a bottle which has been capped, or a bottle without there being a cap in the opposing chuck. A light spring 17 keeps the telescoping parts normally extended. The upper toggle member 18 is hinged to a vertically sliding screwthreaded shank 19 which threads into a shank 20 of the table 21 which supports the avoidable in a lot of bottles which the machine may be called on to cap. The pressure is limited to the tension of this spring during the initial approach of the support for the bottle toward the pressure-applying head until the crank shaft reaches a certain definite point in its revolution and the toggle comes within a certain definite distance from straight. Then a toothed latch. pivoted to the lower of the telescoping parts of the lower toggle member is brought into engagement with teeth on the shank of the upper telescoping part and'the two rigidly connected. This engagement is efl'ected by contact of the back of the latch with a springpressed pad'23. Hooks 24 24 engage the lower of the telescoping parts of the lower toggle member through a bar attached thereto and make the engagement of the latch more secure. From this point in the movement and during the further straightening of the toggle the spring between the telescoping parts is thereby cut out of action, and as the pressure is no longer limited thereby, it will increase with further straightening of the toggle, depending upon .the resistance to compression by the packing in the cap, unless or until further limited by the yielding of the heavy springs through which the eye-bolts are hung. The hooks hold the latch in engagement .until the toggle returns to its initial bent condition, there by promptly lowering the table since the telescoping parts are thereby kept from extending while the toggle is flexing, and releasing the bottle to permit its removal, and to permit other operations of the machine to take place. When the toggle is fully bentthe ends of the hooks strike studs 25 25, the telescoping parts are unlatched thereby and return to their normal extended relation. A

\ clips. The caps fall from the pasteboard containers into the metal tubes and rest on the table, except that one tube overlies an ejector slide 32 which carries cap grippers 33 and slides in a groove in the table. .The grippers are drawn together by a spring 34. The

ejector slide is actuated from a cam 35,

through a rod 36, arm 37, rock-shaft 38, and arm 39. On the rock-shaft is also an arm 40 whichconnects throu h a link 41 with an oscillating ring 42. Tl'llS ring carries a pawl 43 which engages notches in the turret or rotatable carrier 44 to revolve the same with a step-by-step movement. The turret is mousse I 83 mounted on a horizontal stud 45 which projects from the head of the column of the machine. A. series of chucks or pressure-' applying sealing heads 46 46, suitably formed for holding the caps and applying the caps to the bottles are setin the convex periphery of the turret. Each one is brought in turn into sealing position over the table on which the bottles are supported, and constitutes a pressure applying head for applying a cap and eii'eoting the closure of the cap on the mouth of a bottle upon the application of pressure in the direction of the bottle axis through the rising of the table as detailed in 1 1y above mentioned application for Letters Patent of the United States Serial No. 223,088. Latches 4:? keep the cap from falling out. Each cap as ejected is held by the grippers over the uppermost chuck in the turret and under a punch 48. The punch it under control of a cam 49, rod 50, and connecting arm 51, and descends at the proper time, drives the cap through the grippers, and seats it in the chuck. A turret-bolt 52 positively locks the turret. The bolt is forced into locking position by a spring 53, and is retracted by a finger v54 which is carried by the oscillating ring. Behind the bolt is an angle lever 55 which connects through a rod 56 with an arm of the wedge through which the machine is stopped and started,

and prevents the starting of the machine if the turret is not in position with a chuck directly over the supporting table for the bottle.
