the drawings, referring to Patented Aug. 4, 1931 PATENT OFFICE RALPH T. SALSBURY, OF OAKLAND, CALIFORNIA BOTTLE CAPPER Application filed April 29,

This invention relates to improvements in bottle cappers and more particularly to machines for crimping crown caps on bottle necks. 7 Among the objects of the invention is to provide a simple, sturdy and effective capper.

Another object is to provide a capper easily adjustable to various sizes of bottles.

A further object is to. provide a uniform capping stroke and application of power regardless of the height of the bottle. Other objects will appear as the description progresses.

In this specification and the accompanying drawings, the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this form because it may be embodied in other forms. It is also to be understood that in and by the claims following the description it is desired to cover the invention in whatsoever form it may be embodied.

In the one sheet of drawings:

Fig. 1 is a side elevation of a bottle capper constructed in accordance with this invention.

Fig. 2 is an enlarged detail of the rack and pinion mechanism partly in vertical section on the line IIII, Fig. 1.

Fig. 3 is a similar view of the same taken on the line III-III, Fig. 2.

In detail the construction illustrated in Fig. 1, comprises the base 1, having the upright standard 2 fixed therein. This base is adapted to be fastened to a bench, if required, and is preferably supplied with a resilient rubber pad 3 upon which the bottle X sits.

The upper portion of the standard 2 has the rack teeth 4 milled transversely therein, from below the head 5 downward a sufficient distance to accommodate the smaller sizes of bottles. This standard may be a length of cold rolled rod.

The capping unit comprises a traveler A, preferably an integral casting, having the annular guides 6, 7 encircling the standard This traveler has the transverse hubs 8,

9, see Fig. 2. The hub 9 is bored to receive 1930. Serial No. 448,225.

the diameter of the shaft 10, of the pinion l1 milled into the body thereof. The diameter of the shaft is turned down to form the stem 12 fitting the bore in the hub 8, against which the end of the pinion 11 abuts.

The stem 12 has a transverse hole therein,

' adjacent its rounded end 13, to receive the bent end 14 of the expansion spring 15 encircling the stem 12. The opposite bent end 16 of this spring engages a socket hole in the hub 8 at 16.

This spring 15 of expansion to seated against performs the dual function keep the pinion 11 laterally the hub 8, and the additional function of torsion to restore the pinion to the inoperative position, after it has been rotated by means of the operating lever 17 extending through the head 10, and provided with the comfortable handle 17 The torsion of the -spring 15 holds the lever 17 normally against the pin 18 projecting from the side of the traveler. The opposite end 17 of the lever protruding through the head is adapted to stop against the pin 18 to prevent undue strain on the spring 15, such as would unseat either of its ends 14, 16 from their respective sockets.

The pinion 11 is held in mesh with the rack teeth 4; by the expansion of the spring 15. Raising and lowering the lever 17 rotates the pinion to raise and lower the traveler on the standard.

The operating level of the traveler is readily adjustable by grasping the traveler in the left hand with the end 13 of the stem against the palm. A slight pressure inward overcomes the tension of the spring 15, disengages the pinion from the rack, permitting the traveler to be raised and lowered at will, with respect to the height of the bottle X. When the pressure is released the spring snaps the pinion 11 back into mesh with the rack 4: at the selected level. The pin 18 should be long enough to retain the lever 17 in upright position during the lateral shifting of the pinion to disengage it from the rack.

The crimping ferrule 19 is screwed onto the threaded stud 20 fixed in the traveler.

The edge of this ferrule is flanged outwardly lower edge of the ferrule clears to engage the fluted edge X of the crown cap X, to compress the cap about the bead forming the mouth of the bottle, in the conventional manner.

If the teeth in the rack A and the pinion 11 are closely fitted and the straps 6, 7 snugly engage the standard 4,110 of the traveler A is requirec. If, however, the workmanship is inferior, it may be desirable to mill the slot 21 in. the back of the standard to guide the stud'22 fixed in the strap 6 to prevent lateral play of the .traveler A on the standard.

' The machine operates substantially as fol lows: The filled bottle X is placed upon the pad 3, the traveler A is lowered until the g the cap X resting upon the top of the bottle. The handle 18 is then pulled down, which causes the pinion 11 to travel down the rack 4L and coinpress the edge X of the cap within the ferrule, as'describe'd. When the handle 1'8 is released;:th-e spring 15 restores it to the position shown in dotted lines Fig.1 leaving both hands :of the operator free to handle the bottles and repeat theopera-tion.

Having thus described this invention, what I claim and desire to secure by Letters Patent is: V

1. A bottle capper comprising a lease; a standard fixed to said base and' having :a toothed rack thereon; a traveler guided :on said standard; a transverse shaftprotruc'ling through said traveler and having int'e gral pinion teeth engaging saidrack; means for rotating said shaft; a torsion spring en'- g-aging said shaft and traveler and expandingbe tween said traveler and the end of said shaft.

2. A bottle cap-per comprising a base; a

standard fixed to said base and having a toothed rack thereon; a traveler guided on said standard; a transverse shaft protruding through said traveler; a pinion on said shaft engaging said rack; a lever fixed in one end of said shaft, and a spring encircling said shaft having its opposite ends engaging sai'd shaft and traveler respectively;

A bottle capper comprising a standard having rack teeth therein; a traveler guided on said standard and having capping means thereon; a transverse shaft protruding through said traveler-and having pinion teeth engaging said rack teeth; a lev'er'on said shaft; a stop on said traveler engaging said lever; a torsion spring engaging said shaft and traveler and expanding between said traveler and the end of said shaft. 7

4. A bottle capper comprising a reund standard having. rack teeth therein; a tr-av eler encircling said standard and having capping means thereon; av transverse shaft having. a reduced stem and protruding through said traveler and having pinion teeth engaging said rack teeth;'a stop pin further g n projecting from said traveler; a lever extending through said shaft and adapted to engage both sides of said stop pin respectively; a torsion spring encircling said stem and having its ends engaging said stem and traveler respectively and expanding bet-ween said traveler and the end of said stem.

A bottle capper comprising a round standard having rack teeth therein and a longitudinal slot therein; a traveler encircling said standard and having capping means thereon; a transverse shaft having a said traveler; a lever extending through said traveler and having pinion teeth engaging said rack teeth; a stop pin projecting from said'trave lerg; 'a lever extending through said shaft and adapted to engage both sides of said stoop pin respectively; torsion spring encircling said stem and having its ends engaging said stem and travelerrespectively and expanding between said traveler and the end of said stem, and a stud on said traveler engaging said slot the standard.

In testimony whereof I have hereunto set my hand this 2 1th day of April 71:93.0,a

RALPH T. SALS'BURY.
