CAN-COVER.

' Application filed May 9,

To all whomitmay concern: v

Be it' known that I, JAMES R. PRATT, citizen of the United States, residin' at enison, in the county of Grayson and 1 late Texas, 1 i and liquids and refers more especially to vessels applied to the opening and removed rovidedwith stopping the filling constructed of metal screw or slip caps for orifice.

The chief objects of my invention are to I provide a can closure that can be readily thererom, such closure having retaining means or preventing its displacement or loss; and to furnish a connecting means adapted to secure the cap or stopper to the mam body of the vessel and at the same time permit a sufficiently free moveu'lent of the cover to prevent interference with the insertion of a cup having 1s specification andin which: Figure 1 1s a sectional view of showing a retaining inside the cap a can top, device located entirely Figs. 2 and 3show modifications of the attachment illustrated in Fig. 1

I ferring to .the drawing in, detail, the numeral 7 indicates the top of a can or nipple having threads formed therein. A cup 8 of the usual construction and furnished with a sealing disk 9 has threads 10 adapted Specification of Letters Patent.

to engage the threads of said nipple and is urnished with a lug 11' fixed in the center of the top of the cover. To this lug is piv- I otally attached a connectlng member 12 bent {at a right angle at the point 13 to form a. vertical portion 14 which passesfreely through holes in the flanges 15 of a bracket f 16 secured to the inside assembling the parts the lower free extremity I of the vertical arm 14 is bent into an I. formed with a simple angle 17 to prevent its ecoming disengaged from the bracket flanges.

It will be seen that the device is entirely the nipple 7 in engagement therewith. The Vertical portion 14 is made of suflicient length in all the. forms shown to allow the cap to beelevated high enough to permit it to clear the nipple atter which it can be swung upon the centers of motion quickly replaced upon its seat and is sufii ciently out of the way to allow the introduction of a funnel or tube into the orifice.

It will be readily understood that the conmeeting member has a pivotal connection with the cover center for the two fold pur 0% of permitting the necessary rotary motion to-be given to the said cover to engage and disengage it from its threaded scat upon 7 the nipple. In the modified form it may sometimes be considered desirable to remove the cap so as to be entirely displaced from the nipple and thus avoid any interference with a free opening. For this purpose I have designed the modifications illustrated in 3. In the former case the lug 11 is replaced by an L shaped rod or stem 18 projecting downward from the under surface of the heap 8, the-upright'memher 14 of the con necting link engaging a modified form of bracket '19 which of the can, which is to-encroach upon the opening of the nipple, an orifice 22 being formed for the passage of the liquid contents of the can. In the case thus illustrated the ca may be swung away f om the nipple after lieing 1121- Figs. 2 and to allow opening in said arm contracted to a round hole for the passage of the stern as in the other cases shown. A further advantage in this form lies in the fact that the vertical member 14 is shortened so that it does not extend below' the nipple and this formfof connection can thus he used'whether the to of the can body does or doesnot encronc upon the opening of'the nipple skirt, since it needs only the single point of support 19.

In all the modificationshereinbefore described the caps shown therewith have been provided with screw connection with the thinihle or nipple of the can. In Fig. 4 is illustrated an adaptation of the connecting device for use with a slip ca 23 which en} gages the external surface 0 an oil on 2a the stem 25 being located eccentricall in the top of thecap and extending interiorly thereto, being permanently attached to the cup by a clip 26 which perinitsfree play to said stem, the latter being of suiiicient length the cover or cap to he slipped free from its seat, when it can be rotated to the position shown in dotted lines.

While I have shown my improved can closure adapted tocertain forms of nipples and applied to the filling apertures it is evident that the device is equally applicable to containers of different design, and the discharge orificesas well, without departing from the spiritand scope-of the invention and I do not wisln'therefore, to be limited in its applicatiomnor to the precise details of construction and application set forth.

Having thus described my invention what I claim as new is l. In combination with a container having a suitable neck, a closure, consisting of ceases a ca adapted to fit said neck, perforated gui e secured to the inner surface of said neck, a bent arm pivotally connectedwith the inner surface of saidcap, and having a ide.

2. In combination with a container hav ing a threaded extension, a cap adapted to enga e said extension, a bent arm arranged within said extension, and pivota'iiy engag ing the center of said cap, a guide secured within said,container and having alined openings therein, and means connecting said arm and guide said means adapted to permit the cap to be turned on its vertical axis, to be raised and lowered relative to said container and to be swung toward and away from said extension, substantially as set forth. I I

3. In combination with a container having an extension with an opening therein,

a cap for saide'xtension, and means attaching said ,cap'to'said extension said means consisting of 'a'bearin'g arranged within said container, a rod slidably mounted in said beari and havin a stop thereon and means pivota y and slidiiblyconnecting said cap with said rod.

4. A device for securing a's'crew @ip to a conta ner, consisting of a bearing R18C6'887 cured to said: container, an arm pivotally mounted in said bearing and having anelongated eye formed therein, and means connecting said eye with the top of the cap, said means adapted to-limit the vertical movement of the cap relative to the container. v

'5. In means for securing a screw-cap to a container, a rod secured to the cap and depending therefrom within the container, means on said rod for limiting the vertical movement of said cap relative to-the container, and means connecting said rod with' said. container, and adapted to 'permit the rotation ofsaid cap on said container.
