casein-can TOP.

' Specification of Letters Patent.

- Patented Oct. 3, 1916,

To all whom it may concern:

- Be it known that we, WILLIAM L. CASH and IoN B. CRoWE, citizens of the United States, and residents of Graham, in the county of Muhlenberg and State of Kentucky, have made an Improvement in Carbid-Can Tops, of which the following is a specification.

Our present invention is an improvement upon the carbid can for which we havereceived Letters Patent, No. 1,164,465, dated Dec. 14, 1915.

The improvement pertains particularly to i the means for locking the top or discharge spout of the can to the body of the latter detachably.

The details of construction, combination, and operation of the invention are as hereinafter described, and illustrated in the. accompanying drawing, in which- Figure 1 is a vertical section of the canv and holder. Fig. 2 is a partial section at right angles to Fig. 1 and taken substantially on the line 2-2 of the said figure, the locking devices being engaged with the flange of the can body. Fig. 3 is a perspective view of the cover looking from below, the locking devices being shown disengaged. Fig. 4 is a similar view of one of the looking' members.

The cylindrical body 1 of the carbid' holder is pivoted between the vertical arms or supports 2 which are secured upon a flat base 3 as described and illustrated in our aforesaid patent. The body of the top or cover 4 has substantially the form of a truncated cone. The nozzle or spout 5 has a cap 6 as in our original invention. Two (2) spring locking devices are applied to the conical cover 4; The chief element of these is represented detached in Fig. 4, the same being a rod 7 having a cross handle 8 at its upper end and a lateral prong or arm 9 at its lower end. This device is held rotatably in a vertical, tubular guide 10, which is fixed in an annular bracket 11 that projects through the conical cover .and is soldered in place. tubular guide is cut away on the side adj acent to the pendent flange 12 of the cover. The portion thus cut awayprovides space forthe rotationof the arm 9 of the locking The lower end of the device. The pendent portion 13 of the tubular guide is notched at its end as shown in Fig. 8. A spiral spring 14' encircles the portion of the rod of the locking device that projects above the tubular guide 10.

The operation of the locking devices will now be understood. Asshown in Fig. 2, the

two sets of locking devices are arrangedon opposite sides of the top or cover; The said top 4 has a horizontaljflange l5 and a vertical flange 12 is pendent from the latter. In applying the can top tothe can body its vertical flange abuts the annular flange 16 of the body and the horizontal flange 15 of the cover rests upon the body flange 16. Before the can cover can be thus applied the locking devices must be adjusted in the position represented in Fig. 2; that is to say, the rods 7 are pushed down against the tension of the springs 14 and .at the same time rotated so that their lateral arms 9 will" be turned under the downwardly projecting ends 13 of the tubular guides and engage in the notches with which the latter are provided. In this position, that is to say, when the horizontal arms of the lockingdevices are turned inward and locked. with the tubular guides, it is obvious they do not interfere with the insertion or removal of the cover 4; but when the cover has been set in place, as indicated in Fig. 2, the locking devices 7 are disengaged from the notches of the tubular guides and turned half way around, by which they assume the position indicated in Figs. 2 and 8. The springs 14 are attached .at their respective ends to the rod 7, and, consequently, when the rods are pressed down to-clear the notches 13 of the pendent guides, the springs 14 will automatically rotate the locking devices half way around, or in other words throw them into the position shown in Fig. 2; so that the arms 9 project under the flange 16 of the body and thus efl'ectively lock the cover of the can to the body. The springs are so attached that they will hold the locking devices in this position, unless rotated manually with sufficient force to -overcome the tension of the springs. It is apparent that the expansion ofthe springs draws the arms body, '55 that the cover is held tightly in place, unless the locking devices be manually. manipulated to effect their disengagement, as will be readily understood from the foregoing description.

To provide for more effective engagement of the locking device with the pendent notched end of the tubular guides, a flat shoulder 17 is formed (see Fig. 4) at the' junction of the rod 7 with its lateral arm 9. A piece of sheet metallS (see Fig. 3) is soldered or otherwise attached to the inner side of the cover adjacent to its rim and projects laterally as shown. This device serves to" prevent carbid particles from lodging in the angle between the top and inslde wall of the head of the can, and the device is arranged midway between the locking devices so that the outward passage or discharge of carbid is not interferred with by the portions of the locking device that 'project'belowthe can cover.

We claim v A carbid can having a flanged head, a detachable cover, the latter provided with ver tical tubular guides which extend below the cover and are cut away on the outer side adjacent to. the rim of the cover, hookshaped' devices which are slidable and rotatable in said guides, spiral expansion springs applied to the upper ends of the lockingdevices exterior to the cover, the locking"devices being thus held engaged with the head of the can when rotated to the outer position, and in engagement with the tubular guides when rotated to the inner or outer posititon, as described.
