Be-it known that'I, THOMAS J. LEVEY, a citizen of the United States of America, residing at Washington, District of Columbia, have invented certain new-and useful Improvements in Bottle-Capping Machines, of

drawing:

This invention relates tov bottle cappin the construction and to increase the eifi- 'ith this and other objects in. view, the invention consists n certain, novel features.

scribed and then'specifically pointed out in the claims.

In the drawingsemployed for illustrating an embodiment of the invention, Figure 1 represents a side elevation, partly in section, of the improved apparatus,'Fig. 2 is a front elevation of the improved a aratus with the operating lever in section, Fig. 3 is a transverse section on the line 3-3 of Fig. 1, Fig. 4 is an enlarged sectional detail of the main 0 crating ortion of the device, Fig. 5 is a (l tached etail view enlarged, of the weighted of the tubular capping member, Fig. 7 is a bottom plan view of the tubular capping the plunger rod of the capping mechanism detached.

The improved device is designed tobe em-' ployed for attaching metal caps to bottles and like receptacles, more particularly to bottles and like receptacles containing efiervescentliquids or liquids under pressure, and for the purpose of illustration, the device is shown arranged for applying caps of this character to the conventional form of bottle, a portion of one of which is shown in conncction with F ig. 4. p

The improved device comprises a supporting standard 10, preferably ribbed as represented in Fig. 3, to secure the requisite strength without adding undue weight, and with alaterally extending base or foot. 11. Webs 12 are arranged between the vertical portion 10 and the base portion 11, and be- Specification of Letters Patent.

fill:v upon which the bottle to capped is posed. The block 13 is arranged with its rear edge spaced away from the front of the standard portion 10, to leave a cavity 14 into which fragments of glass or other material which may be accidentally broken off from the bottles will find their way, and thus avoid Disposed upon block 13 are two stop blocks 15-16, having their contiguous faces reversely inclined and against which the bottle bears as indicated by the dotted circle in F ig. 3, the two members 1516, thus iositioning the bottle accurately beneath the capping mechanism.

Thebase member 11 is provided with numerous apertures 17 to receive holding bolts or screws to enable the base with its standard 10 to be secured to a suitable foundation, when it is desired to so support the device, and the standard 10 is provided with lateral wings 18 provided with bolt or screw receiving apertures, to enable the device to be attached to a vertical wall or other su'p ort if desired. Opposite the lower pair of t e lat- -'t is means the device may 'be used in any desired manner.

' Extending forwardly of the standard 10 intermediate its ends is a web 20 to the outer end of which is secured an integral sleeve 21,

said sleeve receiving and formin a working barrel for a plunger 22." The p unger 22 is reduced at its lower end to receive a-tubular capping member 23, the capping memberlte ing secured .in tending throug reduced ortion of the shown in i s. 1 and 4.

plunger as clearly The tubular, ca ping member 23 isforined place byv transverse pins'24 exthe cap member and into the with. two interna annular ribs 255- 26,. the

rib 26 being slightly larger than the rib 25, or with the inner diameter of the rib 25 sli 'htly larger than the inner diameter of the rib 26, the ribs being connected by inclined faces or ortions, as shown more clearly in Fig. 4. y this arrangement the inner surface 0" the incline for a relatively'sh'ort distance, then inclinedoutwardly at a longer lncllne, and

2 tubular capping member 23'at the 0 en end is first inclined inwardly at a relat ve ysharp inclinedinwardly again at a still longer incline, terminating at the upperedge of the rib 26 and thenceextending 'orlzontally. to

'the main inner face of the tubular member. .For the'purpose of clearness-in the description of-the o eration, the lower inclined portionfof the r1 25 is designated 27, the upper end of the inclined portion 25 is designated 28,. the longer inclined portionof the rib 26 is designated 29, while the square or lateral shoulder of the rib 26 is designated 30. The

lower lportion of the tubular capping member 23 inc uding the ribs 25 -3.6 is-formed with a plurality of clefts represented at 31, and extendinglongitudinal y of the tubular capping member from its lower end for approximately one-half its length, so that the cleft lower ,portion of the member 23 may be'distended lon itudinal under-pressure during th? capping operation, as. hereafter explained.

The plun er 22 is formed with an internal aperture, and slidably disposed in tins aperture is a rod 32, the lower end of the rod isthreaded as at 33 to receive a capping head .34, the outer annular surface of the lower ortion of the head 34 being cylindrical anr the upper portion inclined inwardly and conformingsubstantially to the inclined surfaces'28, 29 of the member 23,

but of less diameter than the same. The cylindricalportion ol' the head 34 is preferably connected rod 32 yieldably in their lower position. 'lheupper end of the rod 32 above the plunger 22 18 formed with a T-head 39, and pivoted at 40 to thisT'head is a lever 41, bifurcated at its inner end to bear upon opposite-sides of the T-head-Bf) and with a weight 42 at its free outer end. The lever 41 is formed with cam fares 4-3 upon its bifurcated portion adapted to bear upon the upper face of the plunger 22, the lever 41 being also provided with an elongated slot 44, the

object to be hereafter explained.

Pivotod at 45 in the uppi 1' end of the. standard 10 is an operating lever-'46, and the plunger 22 is provided with an upwardly extending shank or stem 47 coupled by a link to the lever 46 by pins 49--5(). By this arrangement it will be obvious that the vertical movement of the lever 46 will 0 erate the plunger 22. Depending from the ever 46 is a rod 51, the rod extending through the slot 44 of the lever 41 and with an enlarged head 52 at its lower end, the head preventing the rod 51 from being disengaged from the slot in the lever 41. The lever 46 extends rearwardly of the standard 10 for a short distance and is formed with a terminal hook 53 to receive one end of a spring 54, the lower end of the spring'connected to a threaded rod 55 provided with a wing nut 56 bearing beneath a bracket 57 attached as by a bolt 58 to the standard 10. 'l he spring 4 operates to return the lever 46 and the plunger 22 to their normal elevated positions, and the threaded rod 55 and its nut 56 enable the tension of-the spring to be regulated as reuired.

With a device thus constructed the o eration is as follows: 'i he metal caps (J, \v iioh are to be attached to the bottle neck B are provided in blank, either as flat disks, or as ,block 13 and against the blocks 15--16 ith its upper end beneath the lower edge-of the slittedorrleft member 23, the parts b ing in the position shown in Fig. 1. is shown in Fig. l. oft-he drawings, the parts are in the position they assume when the tubular capping mcmberQB has engagedthe capi, and the head 34 is resting upon said 'cap. In this position, the operating lever 46 has been moved downwardly from the incline at which it normally rests when in the inactive position, to a position substantially horizontal as shown in said high 1. 'lhis downward move.- mcnt ol' the operating lever 46 has moved the capping memberpartly over the cap C, the cap being permitted to enter the capping member on ing to the beveled or inclined iace 27 provided at the lower end ofsaid capping member. The head 34 is permitted to move down to this position, owing to sulhcicnt clearance being provided for such movement by the beveledorinclinedportion282!l provided n the. capping member 23. l pon l'urt-her downward-movcment of the lever 46,

the capping member extends over the cap,

the rlefts in the capping member permitting the latter to expand slightly, yet at the same tii'ne maintaining a strong inward pressure upon the cap. Upon this further downward movement of the capping member 23, the head 34 with its rod remains stationary, while the weightcd'end 42 of the lever 41 follows the downward movement of the plunger and capping member, until, when the extreme. lower position of the capping member is reached, the lever has assunu-d the position shown in Fig. 4 of the drawings, aud, bearing by its-cam surfaces 43 constantly upon the upper face of the plunger, the parts are in the loc 'ed position. In this position of the parts the capping of the bottle has been completed, the capping member having crimpcd the edges of the car around the bottle neck. porting frame havingaplungerguide,aplun- Whenthe capping operation is completed, and pressure on the operating lever 46 is relieved, the. spring 54 acts toreturn the operating lever to its elevated position, and during the upward movement of said lever 46, the head 52 of the rod 51 coming in engagement with lever 41, lifts this lever and returns it along with the lever 46, to the elevated position, releasing the compression on spring 38, and allowing this spring to act to force the head 34 downward to the position shown in Fig. l, the capping member moves ofl' the capped bottle, the parts have been restored to their normal position and are ready for the capping of another bottle. v

- Disposed within the tubular member 23 and between the tubular member and the extension 37 of the head member 34 is a stop sleeve 58, which is supported-on the lateral houlder 30 of the inclined portion 29, thes spring 38 being disposed between this stop s cave and the stem 32, as shown in Fig. 4.. The stop sleeve thus serves to )revent lateral movement of the arts un er. the severe strains to which devices of this character are liable to bejs'ubjected.
