FREDERICK HACHMANN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HACHMANN SPECIALTY COMPANY, A CORPORATION OF MISSOURI.

CONTAINER-CAP.

Speccaton of Letters Patent.

Patented May I, 1917.

Application led February 24, 1914, Serial No. 820,441. Renewed August 12, 1916. Serial No. 114,640.

To all whom t may concern:

Be it known that I, FREDERICK HACH- MANN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Container-Caps, of which the following is a specification.

This invention relates to container caps of the type employed for closing fruit jars or the like, and which embodies a clamping yoke carried by the cap and adapted for engagement with the container to retain the cap in place thereon.

The invention has among its objects to simplify the construction and reduce the cost of production of such devices, and to provide for the yoke being readily and securely, though detachably, engaged with the A further object of the invention is to provide a device of this character wherein the cap and its retaining yoke may be made separately, and thereafter conveniently assembled, and one in which the yoke may be disengaged from the cap at will to permit of the parts being readily and thoroughly cleansed, accidental disengagement of the yoke from the cap being, however, preeluded.

With the above and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter' described.

In the accompanying drawings:

Figure 1 is a top plan view of the cover portion of my improved cap.

Fig. 2 is a sectional view of the same.

Fig. 3 is a bottom plan view of the yoke.

Fig. 4 is a detail perspective view of one corner of the yoke showing the flattened portion by which the yoke is inserted into the slot of the cover.

Fig. 5 is a sectional view of thecover showing the yoke in inserted position.

Fig. 6 is a detail perspective view of the slotted portion of the cover, and the flattened portion of the yoke in an inserting position.

Fig. 7 is a side elevation of my complete cap in position on a container.

The invention in detail consists of a cap or covering 8 provided with a central projecting portion 9 having an elongated central slot 10, the ends of said slots being wider than the center portion, and through the ends l1 is inserted the horizontal or top portion 12 of the yoke; the object of this slot is to allow free movement for the insertion and operation of the yoke, the wide portions of said slot being approximately of the same width as the thickness of the yoke.

In this cap or cover is placed a liner 13 of suitable resilient material to make a per` fect connection between the cap and container top so as to prevent leakage.

The yoke consisting of a horizontal portion 12,1avhich engages and supports the cover, has two downwardly projecting portions 14 provided with loops 15, and terminating in two curved arms 16. One corner of the yoke is attened as indicated by the numeral 17; the object of this is to allow the crown portion 12 of the yoke to be readily inserted into the bearing opening in the cover, and in inserting the same the yoke is held in an inverted position as shown in Figs. 5 and 6 so that the flattened portion will readily pass throu `h the slot 10, allowing the portion 12 of t e yoke to pass into the bearing opening 11. After the yoke has been inserted through the slot and turned t0 its normal position it Yis an utter impossibility for it to become disconnected from the cap unless placed in the same position as indicated in F ig. 6.

In bending the yoke to form the arms 16, the loops 15 are, as seen in Fig. 3, so disposed as to bring the edge 17 of the loop past the center line so that the contacting surface 18 of the curved arms snugly fits around the curvature of the container, making a complete clamp, and bv this formation, when the yoke is clamped around the container, the loops will partially spread while passing over the center line of the container neck, and by means of the spring material of which the same is constructed will hug closely t0 the curvature of the container. By this clamping feature it will be utterly impossible to remove the cap and yoke from the container without exerting pressure against the edges 17 of the loops so as to bring the curved arms away from the container neck.

Having fully described my invention, what I claim is:

l. A container cap having a bearing opening provided with an entrance slot, a cap retaining yoke having a reduced portion formed' and disposed to pass through' said slot for permitting introduction of the yoke into said bearing opening, and means on the yoke for engagement with a container.

2. A container cap having a bearingopening provided with an entrance slot, and a cap retaining ,vokev comprising a crown' portion and depending container engaging arms, one or' said arms having a reduced portion adapted, When the yoke is inverted, to pass through said slot for permitting introduction of said crown portion endWise into said bearing opening.

3. A container Cap comprising a cover stamped ont of a single sheet of material,

its Center portion projecting and provided with an elongated slot, the ends thereof being Wider than the center, a yoke' `formed of a single Wire` suitably bent, the corner of said Wire being flattened for Apermitting the yoke to be inserted in the slot, the ends of said Wire formed into loops, and terminating in Curved arms, substantially as speeiied.

In testimony whereof, I have signed my name to this speoiiication, in presence of two subscribing witnesses. y v
